Abstract

A positioning stand is provided, which comprises: a support; a positioning base, engaged to the support and having an accommodating base at a lateral side thereof; a locking rod, disposed passing through the positioning base and the support and having a locking part in contact with the accommodating base; a knob, connected to an end portion of the locking rod protruding from the support; and a resilient element, disposed between the support and the knob; wherein the knob is capable of changing a position of the locking part through compression of the resilient element and a rotation motion and the support compresses the resilient element to adjust an angle of the support, and the positioning stand is combined with an electronic apparatus, so as to adjust a tilting angle of the electronic apparatus, thus enhancing a cooling effect of the electronic apparatus and increasing comforts of using the electronic apparatus.

Claims

1. A positioning stand, comprising:

a positioning base, having a gear type structure at a lateral side thereof and an accommodating base at the other lateral side, wherein the accommodating base has a first through hole passing through the positioning base;

a support, engaged to the gear type structure and having a second through hole corresponding to the first through hole;

a locking rod, protruding from the support through the first through hole and the second through hole, and having a locking part in contact with the accommodating base;

a knob, connected to an end portion of the locking rod protruding from the support; and

a resilient element, disposed between the support and the knob, so that the knob changes a position of the locking part through compression of the resilient element and a rotation motion and the support compresses the resilient element to adjust an angle of the support.

2. The positioning stand according to claim 1, wherein the accommodating base has a pair of intersecting grooves.

3. The positioning stand according to claim 1, wherein the locking part is a pair of convex bodies connected on two sides of the locking rod, the pair of convex bodies selects to be in contact with one groove through the rotation motion provided by the knob.

4. An electronic apparatus having positioning stands, comprising:

an electronic apparatus, having a slot on each sidewall at two sides respectively;

a pair of positioning stands, connected to the two sidewalls of the electronic apparatus respectively, wherein each positioning stand comprises;

a positioning base, having a gear type structure on a lateral side thereof and an accommodating base on the other lateral side, wherein the accommodating base is accommodated inside the slot on the corresponding sidewall, and has a first through hole passing through the positioning base;

a support, engaged to the gear type structure and having a second through hole corresponding to the first through hole;

a locking rod, protruding from the support through the first through hole and the second through hole, and having a locking part;

a knob, connected to an end portion of the locking rod protruding from the support; and

a resilient element, disposed between the support and the knob, so that the knob drives the locking part to select to be in contact with the accommodating base or in contact with the corresponding sidewall through compression of the resilient element and a rotation motion and the support compresses the resilient element to adjust an angle of the support.

5. The electronic apparatus having positioning stands according to claim 4, wherein the accommodating base has a pair of intersecting grooves.

6. The electronic apparatus having positioning stands according to claim 4, wherein the locking part is a pair of convex bodies connected on two sides of the locking rod, and the pair of convex bodies selects to be in contact with one groove through the rotation motion.

7. The electronic apparatus having positioning stands according to claim 4, wherein a flexible belt is further connected at two ends of the pair of supports.

8. The electronic apparatus having positioning stands according to claim 7, wherein a third through hole is provided at two ends of the flexible belt respectively, a buckle is sleeved in each third through hole, and the buckle is connected to an end portion of the corresponding support.

9. The electronic apparatus having positioning stands according to claim 4, wherein an end of each locking part is further extended with a convex rod.

10. The electronic apparatus having positioning stands according to claim 9, wherein the electronic apparatus has a strengthened structure at a side of an inner wall surface corresponding to the two sidewalls respectively, so as to support the convex rod.

11. An electronic apparatus having positioning stands, comprising:

an electronic apparatus, having a slot on each sidewall at two sides respectively;

a projection unit, disposed inside the electronic apparatus, for projecting an image; and

a pair of positioning stands, connected to two sidewalls of the electronic apparatus respectively, for adjusting a tilting angle of the electronic apparatus so as to adjust a projection angle of the projection unit, wherein each positioning stand comprises;

a positioning base, having a gear type structure on a lateral side thereof and an accommodating base on the other lateral side, wherein the accommodating base is accommodated inside the slot on the corresponding sidewall, and has a first through hole passing through the positioning base;

a support, engaged to the gear type structure and having a second through hole corresponding to the first through hole;

a locking rod, protruding from the support through the first through hole and the second through hole, and having a locking part;

a knob, connected to an end portion of the locking rod protruding from the support; and

a resilient element, disposed between the support and the knob, so that the knob drives the locking part to select to be in contact with the accommodating base or in contact with the corresponding sidewall through compression of the resilient element and a rotation motion and the support compresses the resilient element to adjust an angle of the support.

12. The electronic apparatus having positioning stands according to claim 11, wherein the accommodating base has a pair of intersecting grooves.

13. The electronic apparatus having positioning stands according to claim 11, wherein the locking part is a pair of convex bodies connected on two sides of the locking rod, the pair of convex bodies select to be in contact with one groove according to the rotation motion.

14. The electronic apparatus having positioning stands according to claim 11, wherein a flexible belt is further connected at two sides of the pair of supports respectively.

15. The electronic apparatus having positioning stands according to claim 14, wherein a third through hole is provided at two ends of the flexible belt respectively, a buckle is sleeved in each third through hole, and the buckle is connected to an end portion of the corresponding support.

16. The electronic apparatus having positioning stands according to claim 11, wherein an end of each locking part is extended with a convex rod, and the electronic apparatus has a strengthened structure at a side of an inner wall surface corresponding to the two sidewalls respectively, so as to support the convex rod.
