DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figure 1-Figure 9 A switch bracket device on an electrical device includes a base plate 1, a mounting opening 2 is provided at the central position of the base plate 1, the base plate 1 is a platform that can be fixed on the electrical device and is used to install the switch. The mounting opening 2 matching the size and shape of the switch is provided on the base plate 1 to facilitate stable installation of the switch.

[0037] A switch is installed at the installation port 2 through an installation component, and the installation component includes a limit groove 3 opened in the base plate 1, and a bidirectional threaded rod 4 is rotatably connected in the limit groove 3. The rod body of the bidirectional threaded rod 4 is symmetrically slidably sleeved with two threaded sleeves 5. The limit groove 3 is square in shape, and the threaded sleeve 5 is slidably connected to the limit groove 3. The square limit groove 3 can limit the threaded sleeve 5, so that the rotation of the bidirectional threaded rod 4 can drive the threaded sleeve 5 to slide horizontally on the rod body of the bidirectional threaded rod 4.

[0038] The threaded sleeve 5 is threadedly matched with the bidirectional threaded rod 4. A handle 6 is coaxially fixed on the right end of the bidirectional threaded rod 4. The handle 6 includes a connecting shaft 61 connected to the bidirectional threaded rod 4. A rotating wheel 62 is connected to the right end of the bidirectional threaded rod 4 to facilitate the rotation of the bidirectional threaded rod 4.

[0039] A pin hole 63 is provided on the connecting shaft 61, and a locking assembly that is plugged into the pin hole 63 is also provided on the base plate 1. The locking assembly includes a fixed block 21 fixedly connected to the base plate 1, and the fixed block 21 is slidably connected with a pin shaft 22. A return spring 23 is connected between the pin shaft 22 and the fixed block 21. The pin shaft 22 is plugged into the pin hole 63 to prevent the bidirectional threaded rod 4 from reversing and causing the switch to fall off.

[0040] Two movable grooves 7 connected to the limiting groove 3 are provided in the base plate 1, and the width of the movable groove 7 is smaller than the width of the limiting groove 3. The lower ends of the two threaded sleeves 5 are fixedly connected with L-shaped connecting rods 8, and the L-shaped connecting rods 8 are arranged through the movable grooves 7. The L-shaped connecting rods 8 are composed of a horizontal rod and a vertical rod whose ends are vertically fixedly connected, and the upper end of the vertical rod is fixedly connected to the threaded sleeve 5. The opposite ends of the two horizontal rods are fixedly connected with clamping plates 9. The clamping plate 9 is a clamp located between the switch and the base plate 1, which is used to provide additional support and fix the switch.

[0041] A buffer assembly 10 is fixedly bonded to the opposite end of the two clamping plates 9. The buffer assembly 10 includes a sliding cavity 101 opened on the clamping plate 9. The sliding cavity 101 is slidably connected with a push plate 102. A plurality of buffer springs 103 are fixedly connected between the push plate 102 and the sliding cavity 101. When used in conjunction with the locking assembly, buffering can be provided to ensure that the switch is stably limited without affecting the plug-in fit between the pin shaft 22 and the pin hole 63.

[0042] A positioning component is also provided on the base plate 1. Specifically, the positioning component includes two mounting grooves 11 symmetrically opened on both sides of the base plate 1. The mounting grooves 11 are slidably connected to the positioning plates 13. The two positioning plates 13 are provided with a rough surface 131 at opposite ends. The rough surface 131 is provided at one end of the positioning plate 13 close to the electrical equipment. The positioning plate 13 contacts the electrical equipment through the rough surface 131, thereby increasing the static friction between the two, so that the base plate 1 is better fixed on the electrical equipment.

[0043] A tension spring 14 is fixedly connected between the positioning plate 13 and the mounting groove 11. The tension spring 14 is always in a stretched state and is not in an extreme stretched state. A guide rod 12 is also provided in the mounting groove 11. The tension spring 14 is always in a stretched state, ensuring that the two positioning plates 13 always have a tendency to move relative to each other, ensuring the stability of the positioning plate 13 fixing the base plate 1 on the electrical equipment.

[0044] The reason why the tension spring 14 is not in the state of ultimate tension is to avoid elastic fatigue of the tension spring 14, increase the service life of the tension spring 14, and reduce the maintenance cost of the bracket.

[0045] The guide rod 12 includes a thick rod 121 fixedly connected to the inner wall of the mounting groove 11, and a guide groove 122 is provided at the opposite ends of the two thick rods 121. The guide groove 122 is slidably connected with a thin rod 123, and the thin rod 123 is never separated from the guide groove 122. The thin rod 123 and the thick rod 121 are slidably matched to provide a guarantee for the horizontal movement of the positioning plate 13, thereby ensuring the stability of the positioning plate 13 in the horizontal direction.

[0046] The tension spring 14 is located on the outside of the guide rod 12. By arranging the guide rod 12 on the inside of the tension spring 14, the spring 14 is prevented from easily undergoing elastic deformation, the service life of the tension spring 14 is increased, the maintenance cost of the bracket is reduced, and the stability of the bracket fixed on the electrical equipment is ensured.

[0047] The front end of the bottom plate 1 is provided with a plurality of limiting components. Specifically, the limiting components include a groove 15 opened at the front end of the bottom plate 1, and a fixing plate 16 is fixedly arranged in the groove 15. The switch is usually connected with a wire to achieve electrical connection with the electrical equipment. By opening the groove 15 on the bottom plate 1 and arranging the fixing plate 16 in the groove 15, instead of directly pressing the wire on the bottom 1 through the pressing plate 19 to limit the wire, the contact area of ​​the wire can be reduced and the clamping pressure on the wire can be increased, so that the limiting effect of the wire is better. When limiting the wire, the pressing plate 19 is pulled forward. The limit spring 18 is stretched, and the distance between the pressure plate 19 and the fixed plate 16 increases. The wires are led between the two fixed plates 16 and the pressure plate 19, and the wires are placed on the arc groove 161 opened on the fixed plate 16. The pressure plate 19 is relaxed. Under the elastic force of the limit spring 18, the pressure plate 19 moves toward the fixed plate 16, and the wires are limited by the contact between the protrusion 20 and the wires in the arc groove 161. By adding a limit component for the wires used to connect the switch, the connection between the wires and the switch is not easy to fall off when the wires are pulled, which brings convenience to use.

[0048] A sliding groove is provided at the front end of the base plate 1, and a sliding rod 17 is slidably connected to the sliding groove. A limiting spring 18 is fixedly connected between the sliding rod 17 and the sliding groove, and the sliding rod 17 is never separated from the sliding groove. A pressing plate 19 is fixedly connected to the front end of the sliding rod 17, and the limiting spring 18 is always in a stretched state and not in an extreme stretched state. The elastic force of the limiting spring 18 causes the pressing plate 19 to move backward and always maintains a tendency to move backward. On the one hand, the limiting effect of the pressing plate 19 on the wires can be ensured, and on the other hand, the pressing plate 19 can be prevented from causing crushing to the wires, thereby protecting the wires.

[0049] An arc groove 161 is provided at the front end of the fixed plate 16, and a protrusion 20 is fixedly provided at the rear end of the pressing plate 19, and the position of the protrusion 20 corresponds to that of the pressing plate 19. By providing the arc groove 161, the wires can be limited to prevent the wires from moving between the pressing plate 19 and the fixed plate 16. Then, by providing a protrusion 20 adapted to the arc groove 161 at the front end of the pressing plate 19, the protrusion 20 is abutted against the wires to ensure the limiting effect of the limiting component on the wires.

[0050] An elastic pad is fixedly bonded to the rear end of the protrusion 20. The protective pad is made of elastic material. The elastic contact between the protective pad and the wire can further protect the wire. On the other hand, the static friction force is increased to improve the limiting effect of the limiting component on the wire.

[0051] The working principle of the present invention is as follows:

[0052] When the bracket is fixed on the electrical device, the positioning plates 13 are pulled in opposite directions to increase the distance between the two positioning plates 13, the tension spring 14 is further stretched, and the two positioning plates 13 are placed on both sides of the electrical device. The positioning plates 13 are loosened, and the two positioning plates 13 move relative to each other and always maintain a tendency to move relative to each other. With the rough surface 131 set at the opposite ends of the two positioning plates 13, the two positioning plates 13 are firmly clamped on the electrical device, which is convenient for fixing and removing the bracket on the electrical device, and the operation is simple;

[0053] When installing the switch on the bracket, place the switch between the two clamping plates 9 at the mounting opening 2, and use the handle 6 to easily rotate the bidirectional threaded rod 4. The square limit groove 3 can limit the threaded sleeve 5, so that the rotation of the bidirectional threaded rod 4 can drive the two threaded sleeves 5 to slide horizontally relative to each other on the rod body of the bidirectional threaded rod 4 until the switch is tightly clamped by the two clamping plates 9;

[0054] When limiting the position of the wires, the pressure plate 19 is pulled forward, the limiting spring 18 is stretched, the distance between the pressure plate 19 and the fixed plate 16 is increased, the wires are led between the two fixed plates 16 and the pressure plate 19, and the wires are placed in the arc groove 161 opened on the fixed plate 16, and the pressure plate 19 is released. Under the elastic force of the limiting spring 18, the pressure plate 19 moves toward the fixed plate 16, and the wires are limited by the contact between the protrusion 20 and the wires in the arc groove 161. By adding a limiting component for the wires used to connect the switch, when the wires are pulled, the connection between the wires and the switch is not easy to fall off, which brings convenience to use.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
