[0029] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —5:

[0030] A housing structure for a circular lock switch includes an upper housing 1 and a lower housing 2. A limiting component 3 is provided on the inner side of the upper housing 1. The limiting component 3 includes a limiting part 31 for lowering a control plate 4 and a connecting part 32 connecting the limiting part 31 and the upper housing 1. A knob 8 is provided in the middle of the top plate 11, and a spring 9 is provided between the knob 8 and the control plate 4.

[0031] like Figure 1-5 As shown, this utility model provides a limiting component 3 on the inner side of the upper shell 1. The limiting part limits the control plate 4 at the bottom, which effectively prevents the control plate 4 from popping out due to the elastic force of the spring 9 during installation. This facilitates the installation of the upper shell 1 and the lower shell 2, effectively improves production efficiency, increases production capacity, and achieves efficient and stable shell locking. It also lays the foundation for future batch automated locking.

[0032] The structure of the limiting component 3 is as follows: Figure 1-4As shown, the upper shell 1 includes a top plate 11 and an outer peripheral wall 12. The connecting part 32 is a vertically arranged connecting plate, with the upper end of the connecting plate connected to the top plate 11. The limiting part 31 is a hook-shaped part provided at the lower end of the connecting plate. The structure is simple and has a good limiting effect.

[0033] To facilitate the insertion of the control board 4 into the hook-shaped part, such as Figure 2 , 4 As shown, the connecting plate is located on the side of the control plate 4, and the hook-shaped part is a right-angled triangle. The lower end of the connecting plate is connected to one of the right-angled sides of the hook-shaped part. The hypotenuse of the hook-shaped part slopes from bottom to top from the side away from the control plate 4 to the side closer to the control plate 4, guiding the control plate 4 to be inserted into the hook-shaped part.

[0034] To better limit the movement of control board 4 and further prevent it from popping out, such as... Figure 2-4 As shown, there are two or more limiting components 3. The control plate 4 has limiting components 3 on both sides of its long side and / or both sides of its short side. The connecting plate is made of elastic material. During the process of the control plate 4 engaging the hook-shaped part, the connecting plate undergoes elastic deformation; after the control plate 4 engages the hook-shaped part, the connecting plate returns to its original shape.

[0035] When installing the control board 4, tilt the control board 4 into place, with one side of the control board 4 engaging the hook-shaped part on one side. Then, pry open the connecting plate on the other side, causing the connecting plate to undergo elastic deformation. The other side of the control board 4 engages the hook-shaped part on the other side. After the control board 4 is installed, loosen the connecting plate, and the connecting plate will return to its original state.

[0036] In order to facilitate the elastic deformation of the connecting plate and ensure the connection strength between the effective connecting plate and the upper shell 1, the side of the connecting plate near the control plate 4 is recessed to form a groove 5, and the groove 5 is located at the lower end of the connecting plate.

[0037] Preferably, there are two limiting components 3, which are located on both sides of the long side of the control plate 4 and near two non-adjacent corners of the control plate 4. This provides a good limiting effect and reduces the number of limiting components 3, making it easier to install the control plate 4.

[0038] Preferably, the elastic material is rubber, elastic plastic, or metal. The elastic plastic is nylon, PE (polyethylene), or ABS plastic (acrylonitrile-butadiene-styrene plastic). In this embodiment, the connecting plate is made of ABS plastic (acrylonitrile-butadiene-styrene plastic).

[0039] To reduce assembly steps and ensure a firm and reliable connection, the connecting plate, hook-shaped part, and upper shell 1 are an integral structure.

[0040] The mounting structure of the upper shell 1 and the lower shell 2 is as follows: Figure 1-5As shown, the upper shell 1 has an upper limit mounting post 6 on its inner side. The upper limit mounting post 6 includes a large cylinder 61 and a small cylinder 62 located below the large cylinder 61. The control plate 4 has a through hole for the small cylinder 62 to pass through. The lower shell 2 has a lower limit mounting post 7 on its inner side. Screws pass through the lower limit mounting post 7 and are screwed to the upper limit mounting post 6. After the upper shell 1 and the lower shell 2 are assembled, the control plate 4 is limited between the large cylinder 61 and the lower limit mounting post 7.

[0041] Furthermore, after assembly, the lower surface of the control plate 4 is higher than the upper surface of the hook-shaped part.

[0042] Furthermore, the lower limit mounting post 7 is provided with mounting holes, which include an upper hole, a middle hole and a small hole arranged from top to bottom. The upper hole is adapted to the small cylinder 62, the middle hole is adapted to the shank of the screw, and the small hole is adapted to the head of the screw.

[0043] To ensure a secure connection between the upper shell 1 and the lower shell 2, four through holes are provided, located at the four corners of the control plate 4, and four upper limit mounting posts 6 and four lower limit mounting posts 7 are provided accordingly.

[0044] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
