[0002] Among the various existing wall switches, the same structure exists under different appearances. Most of these structures are composed of two parts, namely, an inner and outer component, and are composed of a bottom box and a switch body. They have the advantages of simple structure and low cost. Before installation, the bottom box needs to be fixed on the wall. There are two plastic threaded holes on the bottom box for fixing the switch body. During installation, the wires are correctly connected to the switch body first, and the switch body is then threadedly engaged with the threaded holes on the bottom box through two screws of appropriate length, so that the switch body is fixedly installed on the bottom box, so that the switch as a whole will not shake, thereby ensuring people's normal use.

[0003] During the use of the switch, the switch body may be damaged due to aging, human factors or various other factors. When damaged, the switch body and the bottom box need to be disassembled for repair. However, when the switch body and the bottom box are disassembled and assembled many times, the internal threads inside the plastic threaded holes on the bottom box are easily damaged. However, the bottom box is fixed on the wall and cannot be replaced, resulting in the inability of the screws and the threaded holes to engage with each other, and then the switch body cannot be stably installed on the bottom box, which may cause the wires to be exposed, affecting the safety of people's use. Utility Model Content

[0004] The utility model aims to provide a wall-mounted switch that can be installed quickly and easily, so as to solve the problem in the prior art that the internal threads inside the plastic threaded holes on the base box are easily damaged, resulting in the inability of the screws and the threaded holes to threadably engage and stably install the switch body on the base box.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A quick-install wall-mounted switch comprises a box body and a switch seat detachably arranged inside the box body, the upper surface of the switch seat is snap-connected with a shell, movable grooves are respectively provided at opposite ends of the switch seat, a nut is fixedly provided in the movable groove near the bottom of the groove, a bolt threadedly connected to the nut is provided in the movable groove, and a transmission column is fixedly sleeved on the outer side of one end of the bolt away from the nut; a storage groove having the same length direction as the movable groove is provided on the outer side of the switch seat, and the storage groove is connected with the movable groove through a movable hole; an L-shaped fixing piece for fixing the switch seat inside the box body is provided in the movable groove, the fixing piece comprises a connecting end and a fixing end, the connecting end is placed in the movable groove through the movable hole, and is movably sleeved on the outer side of the bolt through the connecting hole, and the fixing end is placed in the storage groove.

[0007] A further technical solution is that rotating blocks are provided on both sides of the connection between the connecting end and the fixed end, and a rotating hole adapted to the rotating block is opened on the inner wall of the movable hole; when the connecting end is placed in the movable groove, the rotating blocks are rotatably connected to the rotating holes respectively.

[0008] A further technical solution is that the inner diameter of the movable hole is larger than the outer diameter of the bolt; and the inner diameter of the movable hole is smaller than the outer diameter of the transmission column.

[0009] A further technical solution is that the end of the fixed end is connected with a protrusion, and a concave hole is opened on the inner wall of the box body; when the fixed end slides up and out of the storage slot and contacts the inner wall of the box body, the protrusion slides into the concave hole.

[0010] A further technical solution is that a plurality of guide posts are arranged on the inner wall of the box body, and a plurality of guide grooves matching the guide posts are arranged on the side of the switch seat.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: by arranging fixings, bolts, nuts and transmission columns, the threaded engagement of the bolts and the nuts will drive the transmission column closer to the connecting end, so that the transmission column contacts and presses the connecting end, causing the end of the fixing end away from the connecting end to slide out of the storage groove and contact the inner wall of the box body, so that a mutual squeezing force is formed between the box body and the switch seat, thereby ensuring that the bottom of the switch seat can be stably fixed inside the box body, avoiding the internal thread inside the plastic threaded hole on the bottom box from being damaged, resulting in the switch body being unable to be stably installed on the bottom box.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Example:

[0019] See also Figures 1 to 4 The utility model shows a quick-install wall-mounted wall switch, comprising a box body 1 and a switch seat 2 detachably arranged inside the box body 1. The box body 1 is provided with a through hole for the wire to pass through the inside thereof. The switch seat 2 is provided with a power input interface and a switch body for electrically connecting with the wire. The power input interface and the switch body are both prior art and are not described in detail here. The upper surface of the switch seat 2 is snap-connected with a shell 3. The opposite two ends of the switch seat 2 are respectively provided with movable grooves 4. A nut 5 is fixedly provided near the bottom of the groove in the movable groove 4. A bolt 6 threadedly connected to the nut 5 is provided in the movable groove 4. A transmission column 7 is fixedly sleeved on the outer side of the end of the bolt 6 away from the nut 5; a storage groove 8 with the same length direction as the movable groove 4 is provided on the outer side of the switch seat 2, and the storage groove 8 is connected to the movable groove 4 through a movable hole 9; an L-shaped fixing member 10 for fixing the switch seat 2 inside the box body 1 is provided in the movable groove 4, and the fixing member 10 includes a connecting end 11 and The fixed end 12 and the connecting end 11 are placed in the movable groove 4 through the movable hole 9, and are movably sleeved on the outside of the bolt 6 through the connecting hole 19. The fixed end 12 is placed in the storage groove 8. In actual use, the box body 1 is first fixedly installed in the wall. The specific installation method is the existing technology and will not be repeated here. The wires are passed through the box body 1 and electrically connected to the power input interface on the switch seat 2. The wires are arranged, and then the bottom of the switch seat 2 is placed in the box body 1. By rotating the transmission column 7, the bolt 6 and the nut 5 are threadedly engaged. The threaded engagement of the bolt 6 and the nut 5 will drive the transmission column 7 to approach the connecting end 11, and finally the transmission column 7 contacts and presses the connecting end 11, causing the end of the fixed end 12 away from the connecting end 11 to slide out of the storage groove 8 and contact the inner wall of the box body 1, so that a mutual extrusion force is formed between the box body 1 and the switch seat 2, thereby ensuring that the switch seat 2 can be stably fixed in the box body 1.

[0020] See also Figure 2 , Figure 3As shown, rotating blocks 13 are provided on both sides of the connection between the connecting end 11 and the fixed end 12, and a rotating hole compatible with the rotating block 13 is opened on the inner wall of the movable hole 9; when the connecting end 11 is placed in the movable groove 4, the rotating blocks 13 are rotatably connected with the rotating holes respectively. In actual use, by setting the rotating block 13, the threaded engagement of the bolt 6 and the nut 5 will drive the transmission column 7 to approach the connecting end 11, and finally the transmission column 7 will contact and press the connecting end 11, so that the fixing piece 10 rotates along the rotating block 13, and then the end of the fixed end 12 is tilted and slid out of the storage slot 8 and contacts the inner wall of the box body 1, ensuring the stability of the end of the fixed end 12 sliding out, and at the same time ensuring that the end of the fixed end 12 will not slide when it contacts the inner wall of the box body 1.

[0021] The inner diameter of the movable hole 9 is larger than the outer diameter of the bolt 6; the inner diameter of the movable hole 9 is smaller than the outer diameter of the transmission column 7. By setting the inner diameter of the movable hole 9 to be larger than the outer diameter of the bolt 6, it is ensured that the bolt 6 will not affect the fixing part 10 when rotating, and at the same time, when the transmission column 7 presses the connecting end 11, a displacement difference can be formed between the movable hole 9 and the bolt 6, so that the end of the fixed end 12 can be tilted and slide out of the storage groove 8. By setting the inner diameter of the movable hole 9 to be smaller than the outer diameter of the transmission column 7, it is ensured that the transmission column 7 can smoothly press the connecting end 11, and the transmission column 7 is prevented from sliding in the connecting hole 19.

[0022] See also Figure 2 , Figure 3 As shown, the end of the fixed end 12 is connected with a protrusion 15, and a concave hole 16 is opened on the inner wall of the box body 1; when the fixed end 12 slides out of the storage slot 8 and conflicts with the inner wall of the box body 1, the protrusion 15 slides into the concave hole 16. By providing the concave hole 16 and the protrusion 15, the sliding phenomenon when the end of the fixed end 12 conflicts with the inner wall of the box body 1 can be avoided, and the stability of the switch seat 2 installed in the box body 1 is improved.

[0023] See also Figure 1 As shown, a plurality of guide posts 17 are provided on the inner wall of the box body 1, and a plurality of guide grooves 18 matching the guide posts 17 are provided on the side of the switch seat 2. By providing the guide posts 17 and the guide grooves 18, during installation, the guide grooves 18 on both sides of the switch seat 2 are aligned with the guide posts 17, and auxiliary positioning can be performed when the bottom of the switch seat 2 is placed inside the box body 1 to avoid the situation where the installation orientation is incorrect.
