[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] The utility model provides a cover structure of a timing switch.

[0026] In this embodiment, referring to Figure 1-6 The cover structure of the timing switch includes a bottom shell 1, a timing switch 2 and a switch cover body 3. The bottom shell includes a base body 4 and a base cover 5 covering the base body 4. The outer ring of the base cover 5 is provided with a covering step 6 for covering the switch cover body. One side of the covering step 6 is provided with an engaging groove 7, and the other side of the covering step is provided with a connecting plate 8. The top of the connecting plate 8 is rotatably connected to a rotating shaft 9, and a pressure plate 10 is connected to the rotating shaft 9. The side wall of the switch cover body is provided with an engaging step 11 that can be engaged with the engaging groove. The side wall on the other side of the switch cover body is provided with a connecting groove 12 for the connecting plate 8 to pass through. The outer side of the connecting groove 12 is provided with an open groove 13, and the step of the open groove 13 is provided with a pressure plate groove 14 adapted to the pressure plate.

[0027] In the above technical solution, by setting mutually interlocking interlocking grooves and interlocking steps and the design of connecting plates and pressure plates, the pressure plate and the connecting plate are rotated together. After the switch cover is closed, the pressure plate can be used to tighten it to ensure the connection stability of the cover, and the switch cover can be quickly and firmly installed and removed without tools. At the same time, it can prevent it from being easily opened by children.

[0028] The specific principle is as follows: when the switch cover needs to be closed, the fitting step of the switch cover is aligned with the fitting groove and inserted, and then the connecting plate is aligned with the connecting groove, and the switch cover is closed on the covering step. Then, the rotating pressure plate is pressed tightly into the pressure plate groove of the step of the opening groove to achieve a simple locking of the cover. After locking, it can prevent the switch cover from being easily opened. At the same time, it enhances the sealing and stability of the cover when closed, and prevents the cover from being accidentally opened due to vibration or external factors. When it needs to be opened, it only needs to rotate the pressure plate out of the pressure plate groove, which is also very convenient for disassembly and assembly.

[0029] Specifically, an introduction slope 15 is provided on one side of the connecting plate.

[0030] The beveled guide design allows the cover to close more smoothly, reducing jamming and improving assembly efficiency. Furthermore, the bevel helps guide the connecting plate precisely into the connecting groove, ensuring optimal locking every time it is closed.

[0031] Specifically, it also includes a compression spring 16. A rotation hole 17 is provided on the top of the connecting plate. The rotating shaft has a "T"-shaped head 18 that rotates with the rotating hole 17. The compression spring is arranged between the "T"-shaped head and the opening step of the rotating hole. The compression spring has an elastic force to pull the rotating shaft back into the rotating hole.

[0032] By adding a compression spring and utilizing the elastic force of the compression spring, the pressure plate can be stably pressed against the pressure plate groove, thereby improving the stability of the cover.

[0033] like Figure 5 As shown, the cross section of the rotating hole is a "T" structure adapted to the "T" head. At the same time, the rotating hole reserves a gap for upward and downward movement to ensure the retraction outflow space of the rotating shaft under the tension of the compression spring.

[0034] Specifically, lead sealing holes 19 are provided on the outer side walls of the connecting plate and the connecting groove.

[0035] Lead-sealed holes provide an additional security measure. Once the timer is properly installed and closed, these holes can be sealed by inserting lead seals, preventing unauthorized personnel from opening the cover and tampering. This is particularly important in applications where strict access control is required.

[0036] Specifically, a socket 20 for plugging and matching with the timer switch is integrally formed on one end of the base body.

[0037] The one-piece socket strengthens the connection between the base and the timer switch, reducing the risk of loosening that can occur in traditional split designs. This integrated design also helps reduce production costs and improve overall product consistency. Furthermore, it simplifies the number of parts, lowers assembly costs, and improves assembly quality.

[0038] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
