Abstract
Description
Technical Field
[0001] This utility model belongs to the field of switch technology, and specifically relates to a switch. Background Technology
[0002] A switch is an electronic component that can open a circuit, interrupt current flow, or divert current to another circuit. The most common switches are electromechanical devices operated by humans, which have one or more electronic contacts. A "closed" contact means that the electronic contacts are conducting, allowing current to flow; an "open" switch means that the electronic contacts are not conducting, forming an open circuit, and preventing current from flowing.
[0003] Existing switch fixing structures mostly use direct bolt fastening or simple snap-fit designs. While these can achieve basic fixation, they suffer from low positioning accuracy and difficulty in adjustment. Bolt fastening is prone to localized stress concentration due to differences in installation torque, leading to loosening after long-term use. Snap-fit structures are also prone to wear due to frequent insertion and removal, reducing the reliability of the fixation. Therefore, a switch design is needed to help solve this problem.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This specific embodiment is a switch, such as... Figure 1-5 As shown, the switch includes a controller 1, which has an internal cavity. A mounting frame 2 protrudes from the top of the controller 1, corresponding to the outer edge of the cavity. A mounting plate 4 is snapped onto the mounting frame 2. A snap-fit block 5 protrudes from the inner side of the mounting frame 2. A snap-fit groove 6 is formed on the side of the mounting plate 4. The snap-fit block 5 and the snap-fit groove 6 engage with each other. The engagement of the snap-fit block 5 and the snap-fit groove 6 ensures convenient installation and enhances structural strength. It also facilitates the disassembly and replacement of the mounting plate 4 in subsequent work. The controller 1 has symmetrical mounting holes for bolt fastening. The mounting plate 4 has through holes corresponding to the mounting holes for bolts to pass through. Through the mounting holes and through holes, the controller 1 can be easily fixed in the corresponding position during operation.
[0018] The aforementioned mounting plate 4 has a protruding elastic fitting piece 7. A button 3 is installed directly below the elastic fitting piece 7 in the internal cavity of the controller 1. A switch panel 8 is installed at the top of the controller 1. A wire mounting cavity is opened at the bottom of the controller 1. A wiring assembly 15 is installed in the wire mounting cavity. The wiring assembly 15 includes a mounting base 16 installed in the wire mounting cavity. A fastening cavity for fastening the wire is installed inside the mounting base 16. A fastening bolt 17 is installed on the side of the mounting base 16. The mounting base 16 and the fastening bolt 17 are threaded together. One end of the fastening bolt 17 presses against the inside of the fastening cavity. Through the wiring assembly 15, the wiring assembly 15 presses against the wire through the fastening bolt 17. With the fastening cavity structure of the mounting base 16, the wire is firmly connected, preventing loosening and ensuring that the wire can be stably clamped and installed in the fastening cavity.
[0019] The controller 1 has a positioning cavity inside, and a positioning component 9 for positioning and fastening the controller 1 is installed in the positioning cavity. The positioning component 9 includes a top pressure block 10 symmetrically slidably disposed in the positioning cavity. A lead screw 11 is symmetrically installed through the positioning cavity. The top pressure block 10 and the lead screw 11 are threaded together. A worm gear 12 is sleeved and fixed at the middle section of the lead screw 11. An embedding knob 14 is rotatably embedded on the controller 1. A worm gear 13 is fixed at the bottom of the embedding knob 14. The worm gear 13 and the embedding knob 14 are threaded together. Limiting blocks 102 are symmetrically protruding on both sides of the top pressure block 10. A limiting groove for the sliding of the limiting blocks 102 is installed in the positioning cavity.
[0020] The positioning component 9, through the meshing transmission of the worm gear 12 and worm 13, combined with the threaded engagement of the lead screw 11 and the top pressure block 10, achieves precise top pressure fixation of the controller 1, preventing shaking during installation and testing. The controller contains a chip with a signal receiving device and a control module. The wireless control switch contains a transmitter, which connects to the controller via code and controls its on / off state. The wireless controller has a battery module for easy replacement and power supply. It can be installed in any location covered by the signal of the smart gateway control center through mounting holes or double-sided tape. The wireless controller has the advantages of long transmission distance, strong wall penetration, low power consumption, and low cost. With the controller, it can solve the problem of inconvenient installation location of old-fashioned home switches. The wireless control switch does not require re-drilling and wiring; simply replace the controller with the original switch and rewire it. The wireless control switch can be installed anywhere in the signal coverage area and fixed with traceless tape or mounting holes. If the installation location is not satisfactory, it can be changed at any time, which is convenient, quick, and causes very little damage to the wall. The controller can also be controlled by voice to turn on / off and partially open / close.
[0021] Furthermore, a support pad 101 is provided on the outer side of the top pressing block 10. Several support pads 101 are provided at equal intervals on the top pressing block 10. Through the provided support pads 101, the top pressing block 10 can be prevented from causing damage to the inner surface of the wall during the pressing process, and the overall friction can be reduced during support.
[0022] Working principle: When installing the controller 1, the controller 1 is installed in the corresponding cavity. Rotating the embedded knob 14 causes the worm gear 13 fixed at its bottom to rotate. Through meshing transmission with the worm wheel 12, the lead screw 11 is driven to rotate. The lead screw 11 is threadedly engaged with the two side pressure blocks 10. Under the action of the bidirectional thread, the two side pressure blocks 10 slide along the limiting groove in the positioning cavity and push outwards from the controller 1. The support pad 101 on the outside of the pressure block 10 is tightly attached to the inner surface of the cavity to form a stable fixation.
[0023] The wire is inserted into the fastening cavity of the mounting base 16. Rotating the fastening bolt 17 presses the end of the wire into the bolt for reliable fixation. During operation, pressing the elastic contact piece 7 on the mounting plate 4 triggers the button 3 below it to switch the circuit on and off. The mounting plate 4 engages with the snap-fit block 5 inside the mounting frame 2 via the snap-fit groove 6, allowing for quick assembly and disassembly. The bolts in the mounting holes and through holes ensure the overall structure is stable.
[0024] All technical features in this embodiment can be freely combined according to actual needs.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
