Description

Technical Field

[0001] This utility model relates to the field of wall switch technology, and more specifically to a wall switch mounting base structure. Background Technology

[0002] Currently, wall switches, electronic components installed inside walls to open circuits, interrupt current, or divert it to other circuits, are very common household items. With the continuous improvement of people's living standards and demands for better product usability, and with the increasing number of household appliances, the demand for and application of wall switches are becoming increasingly widespread.

[0003] However, the existing technology has some drawbacks. The existing wall switch base and top cover are connected by screws to the connecting posts inside the base. However, the connecting posts inside this connection method are relatively fragile. Over-tightening the screws may cause excessive internal stress, which can easily lead to breakage. If the connecting post breaks, the base needs to be replaced. During the use of the wall switch, replacing the base requires rewiring, which is very inconvenient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a wall switch mounting base structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing, the housing having a mounting cavity, and a pair of movable connecting devices symmetrically arranged within the mounting cavity. Each movable connecting device includes a movable block and a sliding groove. The movable block has a positioning protrusion that matches the sliding groove, and a threaded mounting hole is formed on the movable block. A limiting groove is provided near the end of the sliding groove, and a limiting piece is provided within the limiting groove. The limiting piece is provided with a locking device adapted to the mounting hole of the movable block.

[0006] The present invention is further configured such that: the locking device includes a plurality of locking plates in a ring array, the locking plates are provided with gaps and together form a horn-shaped structure adapted to the mounting hole, the locking plates can converge toward the center of the mounting hole when pressed; the locking plates are disposed near the back of the limiting plate.

[0007] The present invention is further configured such that: the limiting piece is provided with a bent limiting protrusion adapted to the limiting groove, and the limiting protrusion is located near the end face of the housing.

[0008] The present invention is further configured such that the positioning protrusion on the movable block adopts a T-shaped structure design.

[0009] The present invention is further configured such that: the bottom surface of the mounting cavity is provided with an inlet hole, and the bottom surface of the mounting cavity is provided with a plurality of fixing holes distributed in a circular pattern.

[0010] In summary, this utility model has the following beneficial effects: the sliding groove allows for easy and convenient replacement of the movable block when it is damaged; at the same time, the locking device prevents the screw from being over-tightened, thereby reducing the occurrence of thread stripping in the threaded hole, reducing the stress generated by the movable block due to over-tightening, and thus reducing damage to the movable block.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] This embodiment discloses a wall switch mounting bracket structure, such as... Figures 1 to 4As shown, the device includes a housing with a mounting cavity 1. A pair of movable connecting devices 11 are symmetrically arranged within the mounting cavity 1. Each movable connecting device 11 includes a movable block 3 and a sliding groove 2. The movable block 3 has a positioning protrusion 31 that matches the sliding groove 2. The engagement of the positioning protrusion 31 and the sliding groove 2 quickly guides the connecting block into the correct position, avoiding repeated adjustments during installation and effectively resisting lateral or rotational displacement, ensuring stable and reliable movement of the connecting block and preventing it from easily loosening. The movable block 3 has a threaded mounting hole 32. The housing also includes a mounting cover 5 adapted to the mounting cavity. The mounting cover 5 engages with the mounting hole 32 by rotating and tightening a screw 51, thus engaging with the mounting cavity 1. A limiting groove 21 is provided near the end of the sliding groove 2. A limiting piece 4 is provided within the limiting groove 21 to restrict the movement of the movable block 3, ensuring the movable block 3 is securely positioned within the sliding groove 2. The limiting piece 4 has a locking device 41 adapted to the mounting hole 32 of the movable block 3.

[0018] like Figures 2 to 4 As shown, the locking device 41 includes a plurality of locking plates 411 arranged in a ring array. The locking plates 411 have gaps between them and together form a horn-shaped structure adapted to the mounting hole 32. When pressed, the locking plates 411 converge towards the center of the mounting hole 32. The locking plates 411 are positioned near the back of the limiting plate 4. This back-mounting arrangement allows the movable block 3, which moves upward as the tightening screw 51 is tightened, to contact and press against the limiting plate 4. When the movable block 3 presses against the limiting plate 4, the inner diameter of the horn-shaped structure formed by the locking plates 411 contracts, thereby locking the tightening screw 51 and preventing it from being further screwed in, thus avoiding deformation of the movable block 3 under force.

[0019] To further improve the design, the limiting piece 4 is provided with a bent limiting protrusion 42 that is adapted to the limiting groove 21. The limiting protrusion 42 is located near the end face of the housing. The limiting protrusion 42 is a sheet-like bent protrusion. During installation, it passes through the limiting groove 21. Under the action of its own elasticity, the limiting protrusion 42 deforms and can smoothly enter the limiting groove 21. When it rebounds, it can be locked in the limiting groove 21 and set in the sliding groove 2. The opening of the sliding groove 2 allows the limiting protrusion 42 to be contacted and pressed, making it easy to disassemble.

[0020] To further improve the design, the positioning protrusion 31 on the movable block 3 adopts a T-shaped structure design. The positioning protrusion 31, through the cooperation of the T-shaped head and the sliding groove 2, achieves bidirectional constraint in both the axial and radial directions, which can effectively prevent accidental dislodgement. Compared with the fully enclosed design, the T-shaped structure design saves materials while maintaining strength, making it suitable for narrow spaces and providing better space efficiency.

[0021] To further improve the design, the bottom surface of the mounting cavity 1 is provided with a wire inlet hole 12. The wire inlet hole 12 allows the wire to enter from the bottom, preventing the wire from being exposed and improving safety. The bottom surface of the mounting cavity 1 is provided with a number of circumferentially distributed fixing holes 13, which are used to fix the housing to the wall.

[0022] Working principle of this utility model

[0023] During installation, the wires are passed through the inlet hole 12, and the housing is installed to the wall through the fixing hole 13. The movable block 3 is easily and quickly installed into the mounting cavity 1 through the sliding groove 2. The limiting piece 4 is gently pushed from the opening of the limiting groove 21, and the limiting piece 4 will be firmly set in the limiting groove 21. After completing the wiring of the wall switch body set on the mounting cover 5, the tightening screw 51 is passed through the mounting cover 5, and the locking device 41 that is adapted to the mounting hole 32 cooperates with the mounting hole 32, and the switch is rotated. Tightening screw 51 tightens the screw. When screw 51 is not yet tightened, movable block 3 moves upward along slide groove 2 as screw 51 rotates. When screw 51 is about to be tightened, movable block 3 presses against limit plate 4. Locking plate 411 provided on limit plate 4 deforms under pressure, causing the inner diameter of locking device 41 to shrink and lock screw 51. The locking force increases as screw 51 is tightened. When screw 51 is difficult to continue rotating, installation is complete.

[0024] When disassembling and replacing, reverse the tightening screw 51. As the movable block 3 moves down, the pressure between the movable block 3 and the limiting piece 4 decreases, which reduces the locking force of the locking device 41. The tightening screw 51 can be easily unscrewed, and the mounting cover 5 can be easily removed by simply pressing the limiting protrusion 42 with a screwdriver. The limiting piece 4 can be easily removed from the limiting groove 21, and the movable block 3 can also be easily removed and replaced through the sliding groove 2, which is very convenient.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
