Abstract

The wall fastener for a wireless transmission module includes a supporting frame and a case. The supporting frame has a front face, a rear face, a first engagement portion and a slot. The case has a rear plate which has an outer face, an inner face, a second engagement portion and a stopper. The stopper partially projects out of the outer face. The first and second engagement portions mate and the stopper is received by the slot. The wireless transmission module and the supporting frame are tightly engaged and easily disengaged by a tool.

First claim

What is claimed is:

1. A wall fastener for a wireless transmission module comprising:
a supporting frame having a front face, a rear face, a first engagement portion and a slot; and
a case having a rear plate, the rear plate having an outer face, an inner face, a second engagement portion and a stopper partially projecting out of the outer face, and the case has a recess;
wherein the first and second engagement portions mate and the stopper is received by the slot, wherein the stopper has a flange, one end of the flange connects the rear plate, the other end of the flange is formed with a protruding portion, and the stopper has a pushing portion over and connected to the protruding portion,

wherein when a tool is inserted to the recess of the case, the tool abuts the pushing portion, the stopper is pushed inwardly toward the case, and the stopper is disengaged from the slot thereby.

2. The wall fastener for a wireless transmission module according to claim 1 , wherein a periphery of the case is formed with the recess for receiving the pushing portion.

3. The wall fastener for a wireless transmission module according to claim 1 , wherein the slot cuts through the front and rear faces.

4. The wall fastener for a wireless transmission module according to claim 1 , wherein the first engagement portion is a hook projecting out of the rear face, the second engagement portion is a slit cutting through the outer and the inner faces, and the hook is received by the slit.

5. The wall fastener for a wireless transmission module according to claim 4 , wherein the hook has an arm and a finger, one end of the arm connects the supporting frame, and another end of the arm extends to form the finger.

6. The wall fastener for a wireless transmission module according to claim 5 , wherein an upper edge of the arm abuts an upper wall of the slit, and the finger abuts the inner face of the rear plate.

7. The wall fastener for a wireless transmission module according to claim 5 , wherein sides of the arm abut an inner wall of the slit.

8. The wall fastener for a wireless transmission module according to claim 4 , wherein the hook is a plate, and the slit is a groove.

9. The wall fastener for a wireless transmission module according to claim 1 , wherein the first engagement portion is a slit cutting through the front and the rear faces, the second engagement portion is a hook projecting out of the outer face, and the hook is received by the slit.

10. The wall fastener for a wireless transmission module according to claim 1 , wherein the recess is at a first surface of the case, and the slot is at the second surface of the supporting frame, the first surface and the second surface are substantially perpendicular.
