Abstract

A base structure is used for bearing a display. The base structure includes a support and a seat. The support is connected to a display at one end and detachably disposed on the seat at the other end. The support has a buckling member, and the seat has at least one slot. The buckling member is fitted on the end of the support disposed on the seat, and is rotatable between a release position and a clamping position relative to the support. The buckling member has at least one baffle. When the buckling member is at the release position, the support is detached from the seat by passing the baffle through the slot. When the buckling member is at the clamping position, the baffle and the slot form an angle, and the baffle and the seat have a retaining relationship so as to lock the support on the seat.

Claims

1. A base structure, for bearing a display, comprising:

a seat, including a locking hole and at least one slot extends from a periphery of the locking hole; and

a support, including a bearing portion, a joining portion, and a buckling member, wherein the bearing portion is connected to the display, the joining portion has a pivotal pillar that passes through the locking hole, the buckling member has a main body and at least one baffle, the baffle is disposed on a surface of the main body, and the main body is fitted on the pivotal pillar and is rotatable about the pivotal pillar between a clamping position and a release position,

wherein when the buckling member is at the release position, the support is detached from the seat by respectively passing the main body and the baffle through the locking hole and the slot; and

when the buckling member is at the clamping position, the baffle and the slot form an angle, so as to lock the support on the seat.

2. The base structure according to claim 1, wherein the seat further has a groove and a side wall, and the side wall is embedded in the groove.

3. The base structure according to claim 1, wherein the seat further has at least one positioning hole beside the locking hole, the support further has at least one fixing pillar, and the fixing pillar is inserted in the positioning hole.

4. The base structure according to claim 1, further having a limiting member disposed on the pivotal pillar of the support to limit detachment of the buckling member from the pivotal pillar.

5. The base structure according to claim 4, wherein the limiting member is a screw, the pivotal pillar has a screw hole, one end of the limiting member is locked in the screw hole, and the other end of the limiting member is pressed against the pivotal pillar and the buckling member.

6. The base structure according to claim 1, wherein the joining portion of the support further has a rib, the buckling member has a notch, the rib is located in the notch, and when the buckling member rotates relative to the pivotal pillar, two opposite sidewall surfaces of the buckling member adjacent to the notch are respectively pressed against the rib to limit the buckling member to rotate between the clamping position and the release position.

7. The base structure according to claim 1, wherein the joining portion of the support further has a stopper portion, the buckling member further has an urging portion, and the buckling member is temporarily fixed at the clamping position or the release position by pressing the urging portion against the stopper portion.

8. The base structure according to claim 7, wherein the urging portion has a first fastening portion and a second fastening portion, when the buckling member is at the clamping position, the first fastening portion is fastened to the stopper portion, and when the buckling member is at the release position, the second fastening portion is fastened to the stopper portion.

9. The base structure according to claim 1, further having at least one bump adjacent to the locking hole, and when the buckling member is at the clamping position, the baffle is pressed against the bump.

10. The base structure according to claim 9, further having a guide member disposed between the slot and the bump.

11. The base structure according to claim 10, wherein the guide member has an inclined surface obliquely disposed on the guide member from the slot towards the bump.

12. The base structure according to claim 1, wherein the seat further has an accommodation recess, and the buckling member is accommodated in the accommodation recess.

13. A liquid crystal display (LCD), comprising:

a display;

a seat, under the display, the seat including a locking hole and at least one slot extends from a periphery of the locking hole; and

a support, including a bearing portion, a joining portion, and a buckling member, wherein the bearing portion is connected to the display, the joining portion has a pivotal pillar that passes through the locking hole, the buckling member has a main body and at least one baffle, the baffle is disposed on a surface of the main body, and the main body is fitted on the pivotal pillar and is rotatable about the pivotal pillar between a clamping position and a release position,

wherein when the buckling member is at the release position, the support with the display is detached from the seat by respectively passing the main body and the baffle through the locking hole and the slot; and

when the buckling member is at the clamping position, the baffle and the slot form an angle, so as to lock the support with the display on the seat.

14. The LCD according to claim 13, wherein the seat further has a groove and a side wall, and the side wall is embedded in the groove.

15. The LCD according to claim 13, wherein the seat further has at least one positioning hole beside the locking hole, the support further has at least one fixing pillar, and the fixing pillar is inserted in the positioning hole.

16. The LCD according to claim 13, further having a limiting member disposed on the pivotal pillar of the support to limit detachment of the buckling member from the pivotal pillar.

17. The LCD according to claim 16, wherein the limiting member is a screw, the pivotal pillar has a screw hole, one end of the limiting member is locked in the screw hole, and the other end of the limiting member is pressed against the pivotal pillar and the buckling member.

18. The LCD according to claim 13, wherein the joining portion of the support further has a rib, the buckling member has a notch, the rib is located in the notch, and when the buckling member rotates relative to the pivotal pillar, two opposite sidewall surfaces of the buckling member adjacent to the notch are respectively pressed against the rib to limit the buckling member to rotate between the clamping position and the release position.

19. The LCD according to claim 13, wherein the joining portion of the support further has a stopper portion, the buckling member further has an urging portion, and the buckling member is temporarily fixed at the clamping position or the release position by pressing the urging portion against the stopper portion.

20. The LCD according to claim 19, wherein the urging portion has a first fastening portion and a second fastening portion, when the buckling member is at the clamping position, the first fastening portion is fastened to the stopper portion, and when the buckling member is at the release position, the second fastening portion is fastened to the stopper portion.

21. The LCD according to claim 13, further having at least one bump adjacent to the locking hole, and when the buckling member is at the clamping position, the baffle is pressed against the bump.
