Abstract

A strip lamp made for easy assembly and disassembly contains a U-shaped groove body and a cover made for covering the groove body. The groove body and the cover are attached by a latch on the cover and a matching lock on the groove body on one side, and a pivot made by a V-shaped groove on the cover on the other side. Assembly can be conducted without the use of fasteners so that the strip lamp may be easily assembled.

Claims

1. A strip lamp, comprising:

a groove body,

a cover body covering the groove body,

at least one latching member disposed on the cover body,

the groove body includes a first side wall, and a second side wall, the first side wall includes a blocking portion extending toward the second side wall in a section perpendicular to an extending direction of the groove body, the second side wall includes a latching edge extending toward the first side wall, and the latching member includes a body,

a latching portion extending perpendicular to the body and engaging with the latching edge, and a V-shaped latching groove provided in cooperation with the blocking portion, the latching portion includes a connecting edge connected to the body, and

a right-angled triangular portion, a right-angled side of the right-angled triangular portion is connected to the connecting edge, an other right-angled side is engaged with the latching edge, the V-shaped latching groove is latched on the blocking portion and includes a first side connected to the body, and a second side connected to the first side, an angle between the first side and the body is an obtuse angle in a section perpendicular to the extending direction of the groove body, and the second side is spaced apart from the cover body.

2. The strip lamp as claimed in claim 1, wherein the connecting edge is perpendicular to the body.

3. The strip lamp as claimed in claim 1, wherein the first side wall further includes an abutting portion in a section perpendicular to the extending direction of the groove body, and a transition portion connecting the abutting portion and the blocking portion.

4. The strip lamp as claimed in claim 3, wherein the transition portion is an arc.

5. The strip lamp as claimed in claim 3, wherein an extending direction of the abutting portion is perpendicular to the extending direction of the blocking portion.

6. The strip lamp as claimed in claim 1, wherein a distance between the second side and the cover body is equivalent to a wall thickness of the blocking portion.

7. The strip lamp as claimed in claim 1, wherein a maximum distance of the blocking portion from the cover body is equivalent to a maximum distance of the latching portion from the cover body.

8. The strip lamp as claimed in claim 1, wherein the second side wall further includes at least one detaching hole, and a central axis of the detaching hole intersects a hypotenuse of the right-angled triangular portion in a section perpendicular to the extending direction of the groove body.

9. An assembly method of a strip lamp includes the following steps:

providing a groove body, the groove body including a first side wall, and a second side wall, in a section perpendicular to the extending direction of the groove body, the first side wall includes a blocking portion extending toward the second side wall, the second side wall includes a latching edge extending toward the first side wall;

providing a cover body;

providing a latching member disposed on the cover body, the latching member includes a body, and a latching portion extending perpendicular to the body and engaging with the latching edge, and a V-shaped latching groove disposed in cooperation with the blocking portion, the latching portion includes a connecting edge connected to the body, and a right-angled triangular portion, a right-angled side of the right-angled triangular portion is connected to the connecting edge, an other right-angled side is engaged with the latching edge, the V-shaped latching groove is latched on the blocking portion and includes a first side connected to the body, and a second side connected to the first side, an angle between the first side and the body is an obtuse angle in a section perpendicular to the extending direction of the groove body, and the second side is spaced apart from the cover body;

inserting the blocking portion into a gap between the second side of the V-shaped latching groove and the cover body;

rotating the cover body with a free side of the second side as a center, and the inclined surface of the right-angled triangular portion is in contact with the latching edge; and

pressing the cover body to insert the other right-angled side of the right-angled triangular portion on the latching edge to assemble the cover body onto the groove body to complete the assembly of the strip lamp.

10. A disassembling method of a strip lamp includes the following steps:

providing a strip lamp, the strip lamp includes a groove body, a cover body covering on the groove body, and at least one latching member disposed on the cover body, the groove body includes a first side wall, and a second side wall, the first side wall includes a blocking portion extending toward the second side wall in a section perpendicular to an extending direction of the groove body, the second side wall includes a latching edge extending toward the first side wall, and the latching member includes a body, a latching portion extending perpendicular to the body and engaging with the latching edge, and a V-shaped latching groove provided in cooperation with the blocking portion, the latching portion includes a connecting edge connected to the body, and a right-angled triangular portion, a right-angled side of the right-angled triangular portion is connected to the connecting edge, an other right-angled side is engaged with the latching edge, the V-shaped latching groove is latched on the blocking portion and includes a first side connected to the body, and a second side connected to the first side, an angle between the first side and the body is an obtuse angle in a section perpendicular to the extending direction of the groove body, and the second side is spaced apart from the cover body, the second side wall further includes at least one detaching hole, and a central axis of the detaching hole intersects a hypotenuse of the right-angled triangular portion in a section perpendicular to an extending direction of the groove body;

providing a lever having a diameter corresponding to a diameter of the detaching hole;

inserting the lever into the detaching hole, and an insertion direction of the lever intersects with the central axis of the detaching hole to abut a side wall of the lever at a free side of the right-angled triangular portion;

tilting the lever to disengage the right-angled triangular portion of the latching portion from the latching edge; and

rotating the cover body with a free side of the second side as a center to pry the cover body from the groove body.
