Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically a wall-mounted switch. Background Technology

[0002] The word "switch" is defined as turning on and off. It also refers to an electronic component that can open a circuit, interrupt current, or divert current to other circuits. As the most commonly used control switch in households, the wall-mounted switch has an extremely wide range of applications.

[0003] For example, a smart home wall-mounted switch with patent number 201821221099.8 includes a housing and a fan. The upper end of the housing has a pre-reserved mounting groove. Although it is convenient for quick installation and disassembly and has a hand drying function, during long-term use of the wall-mounted switch, the internal rotating part lacks lubrication during the rotation of the switch button. This can easily cause the switch button to stop halfway through the rotation, stopping between the two extreme positions, resulting in poor contact in the switch structure. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where the switch button easily stops halfway when rotated, stopping between the two extreme positions, causing poor contact in the switch structure, and to propose a wall-mounted switch.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a wall-mounted switch, including a switch housing and a switch button. A limit component is installed on the left end of the switch housing, a notch is machined at the center of the upper rear side of the switch housing, and a groove is machined on the inner wall of the left end of the switch button.

[0007] Preferably, the limiting component includes a slide rod located at the center of the front side of the switch housing. Both sides of the slide rod are fixedly connected to the switch housing via end plates. A sleeve is slidably connected to the upper outer wall of the slide rod. A crossbar is slidably connected to the center of the inner side of the sleeve. A round rod is fixedly connected to the inner wall of the left end of the crossbar. The outer wall of the round rod is slidably connected to a sliding groove. A spring is provided on the left side of the outer wall of the crossbar. Both sides of the spring are fixedly connected to the sleeve and the baffle, respectively.

[0008] Preferably, both outer ends of the end plate are fixedly connected to the switch housing by bolts.

[0009] Preferably, a switch button is installed on the inner front side of the switch housing.

[0010] Preferably, the rear wiring hole of the switch housing is equipped with multiple cables.

[0011] The wall-mounted switch proposed in this utility model has the following advantages:

[0012] Through the cooperation of the switch knob, slide, slide rod, sleeve, and round rod, when the switch button is pressed and rotated, the switch knob can drive the slide at its left end to rotate synchronously. During the rotation, the tilt direction of the slide is constantly changing. Once the switch knob has rotated past the center position, the slide can tilt significantly to the other side. At this time, the spring under compression can push the crossbar to extend to the left. Combined with the sliding property between the sleeve and the slide rod, the crossbar can slide through the round rod to the protruding position at the far left of the slide, thereby pushing the switch knob to the limit position. This effectively avoids the switch button from stopping halfway and stopping between the two limit positions, causing poor contact in the switch structure. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] See attached document Figure 1-3 In this embodiment, a wall-mounted switch includes a switch housing 1 and a switch button 2. A limit component 3 is installed on the left end of the switch housing 1. A notch 5 is machined at the center of the upper rear side of the switch housing 1. A groove 6 is machined on the inner wall of the left end of the switch button 2. The switch button 2 is installed on the front side of the inside of the switch housing 1. Multiple cables 4 are installed in the wiring hole at the rear end of the switch housing 1. The cables 4 are used to connect to external electrical appliances.

[0019] See attached document Figure 2-3 In this embodiment, the limiting component 3 includes a crossbar 3a1, a sleeve 3a2, a spring 3a3, a baffle 3a4, a round rod 3a5, an end plate 3a6, and a sliding rod 3a7.

[0020] The slide bar 3a7 is located at the center of the front side of the switch housing 1. Both sides of the slide bar 3a7 are fixedly connected to the switch housing 1 through the end plate 3a6. The upper part of the outer wall of the slide bar 3a7 is slidably connected to the sleeve 3a2. The center of the inner wall of the sleeve 3a2 is slidably connected to the crossbar 3a1. The inner wall of the left end of the crossbar 3a1 is fixedly connected to the round rod 3a5. The outer wall of the round rod 3a5 is slidably connected to the slide groove 6. A spring 3a3 is provided on the left side of the outer wall of the crossbar 3a1. The elastic coefficient of the spring 3a3 can be determined according to the specific application. Both sides of the spring 3a3 are fixedly connected to the sleeve 3a2 and the baffle 3a4 respectively. Both sides of the outer end of the end plate 3a6 are fixedly connected to the switch housing 1 through bolts.

[0021] Through the cooperation between the switch knob 2, the slide groove 6, the slide rod 3a7, the sleeve 3a2, and the round rod 3a5, when the switch button 2 is pressed and rotated, the switch knob 2 can drive the slide groove 6 at its left end to rotate synchronously. During the rotation, the tilt direction of the slide groove 6 is constantly changing. Once the switch knob 2 has rotated past the center position, the slide groove 6 can tilt significantly to the other side. At this time, the spring 3a3, which is under compression, can push the cross rod 3a1 to extend to the left. Combined with the sliding property between the sleeve 3a2 and the slide rod 3a7, the cross rod 3a1 can slide through the round rod 3a5 to the protruding position at the leftmost part of the slide groove 6, thereby pushing the switch knob 2 to the limit position. This effectively avoids the switch button 2 stopping midway and between the two limit positions, which would cause poor contact in the switch structure.

[0022] Working principle:

[0023] When this wall-mounted switch is needed, the user can first assemble the overall structure as shown in the diagram. After assembly, the entire structure is installed on the wall via the switch housing 1, and the cable 4 is pre-connected. In use, the user can press the switch button 2 to rotate it and control the opening and closing of the switch, thus controlling the electronic components connected to the cable 4. However, with prolonged use, the internal rotating part of the switch button 2 may lack lubrication during rotation, easily causing it to stop midway, between its two extreme positions, resulting in poor contact in the switch structure. Therefore, this design incorporates a limiting component 3 to prevent this during pressing. During the rotation of switch button 2, the switch knob 2 can drive the slide groove 6 at its left end to rotate synchronously. During the rotation, the tilt direction of slide groove 6 is constantly changing. Once switch knob 2 has rotated past the center position, slide groove 6 can tilt significantly to the other side. At this time, spring 3a3, which is under compression, can push crossbar 3a1 to extend to the left. Combined with the sliding between sleeve 3a2 and slide bar 3a7, crossbar 3a1 can slide through round bar 3a5 to the protruding position at the leftmost part of slide groove 6, thereby pushing switch knob 2 to the limit position. This effectively avoids the switch button 2 from stopping in the middle of the rotation and stopping between the two limit positions, which would cause poor contact in the switch structure.
