Abstract

A detachable support is provided. The detachable support includes a first arm having a first connection portion, a second arm having a second connection portion, and a frame. The frame has a first end portion and a second end portion, which are respectively hinged to the first arm and the second arm. The first connection portion and the second connection portion are operable to be inserted and fixed into two grooves respectively, and the two grooves are defined in a housing to be mounted. The first arm has a hole, the housing to be mounted is provided with a spring loaded bolt, and the spring loaded bolt is operable to be inserted into the hole to lock the first arm. No tool is required throughout installation and removal processes of the detachable support according to the present disclosure, thereby improving the efficiency of the installation and removal processes.

Claims

1. A detachable support, comprising:

a first arm having a first connection portion;

a second arm having a second connection portion; and

a frame having a first end portion and a second end portion, which are respectively hinged to the first arm and the second arm;

wherein the first connection portion and the second connection portion are operable to be inserted and fixed into two grooves respectively, the two grooves being defined in a housing to be mounted; and

the first arm has a hole, the housing to be mounted is provided with a spring loaded bolt, and the spring loaded bolt is operable to be inserted into the hole to lock the first arm.

2. The detachable support of claim 1, wherein the first arm and the second arm are symmetrically arranged, the first arm includes a free end and a fixed end, the fixed end being hinged with the first end portion, and the first connection portion of the first arm being located close to the fixed end.

3. The detachable support of claim 2, wherein the width of the fixed end is less than that of the free end.

4. The detachable support of claim 1, further comprising a brake disk and a brake member, wherein the brake disk is fixed on the first arm, the brake member is connected with the frame, and the brake member presses the brake disk to prevent the first arm from rotating relative to the frame.

5. The detachable support of claim 1, wherein the frame comprises:

a U-shaped frame, the first end portion and the second end portion being formed on the U-shaped frame; and

two abutment rods rotatably connected to the U-shaped frame;

wherein each abutment rod is provided with a first abutment member, the U-shaped frame has a second abutment member, and the first abutment member is operable to be abutted with the second abutment member such that each abutment rod is stationary relative to the U-shaped frame.

6. The detachable support of claim 5, wherein the U-shaped frame further has a third abutment element, the first abutment member is operable to be abutted with the third abutment element such that the normal projection of each abutment rod is substantially fell into the normal projection of the U-shaped frame.

7. The detachable support of claim 1, wherein the hole is configured as a countersunk hole.

8. A luminaire, comprising a housing to be mounted and the detachable support of claim 1, wherein:

the housing to be mounted has the two grooves and the spring loaded bolt corresponding to the hole;

the first connection portion of the first arm and the second connection portion of the second arm are operable to be inserted and fixed into the two grooves respectively; and

the spring loaded bolt is operable to be inserted into the hole to lock the first arm.

9. The luminaire of claim 8, further comprising an abutment spring, the abutment spring is abutted between an inner wall of the groove and the first arm, such that the first arm is attached to the inner wall of the groove.

10. The luminaire of claim 8, wherein the length of each of the first arm and the second arm is half of the height of the housing to be mounted.

11. The luminaire of claim 8, wherein a hinge point between the first arm and the frame, a hinge point between the second arm and the frame, and the centroid of the housing to be mounted are collinear.
