[0038] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0039] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer" and other terms used in this utility model to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device and components referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0040] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0041] like Figures 1 to 7 As shown, this utility model embodiment provides an access control switch 100, including a base 10, a micro switch 20, a button 30, and a first spring 40. The base 10 is provided with a first groove 11, and a second groove 12 is provided inside the first groove 11. The micro switch 20 is assembled in the second groove 12, and the button 30 is assembled in the first groove 11. The two ends of the first spring 40 abut against the first groove 11 and the button 30, respectively. The first groove 11 is also provided with a plurality of slots 13 surrounding the second groove 12. The button 30 is provided with a plurality of hooks 31, and each hook 31 is correspondingly engaged with each slot 13. The hooks 31 and slots 13 are connected by a snap-fit ​​connection.

[0042] Based on the above technical solution, during installation, the micro switch 20 is first assembled and secured in the second groove 12. Then, the first spring 40 is assembled in the first groove 11, and the button 30 is assembled in the first groove 11, with the first spring 40 abutting against the button 30. At this time, both ends of the first spring 40 abut against the first groove 11 and the button 30, respectively. Further, each hook 31 on the button 30 is correspondingly snapped into each slot 13 of the base 10, so that the hook 31 and the slot 13 form a snap-fit ​​connection, thereby completing the assembly and fixation of the button 30 on the base 10. In this embodiment, the snap-fit ​​connection between the hook 31 and the slot 13 makes the assembly process of the button 30 on the base 10 simple and convenient, facilitating user replacement of the button 30.

[0043] When installing the access control switch 100, the base 10 is mounted on the surface to be installed (such as a wall), with the button 30 exposed on the surface of the base 10. The user can input an opening command via the button 30. Specifically, pressing the button 30 applies a force to the first spring 40, causing it to compress and deform. The button 30 moves towards the base 10 and triggers the micro switch 20. The micro switch 20 outputs a corresponding command and sends it to the door lock control board, which then issues a corresponding opening command, thereby unlocking the door and opening the door. When the button 30 is released, under the elastic potential energy of the first spring 40, the button 30 moves away from the base 10, returning to its initial position. Furthermore, due to the latching action of the hook 31 and the latch 13, the button 30 will not detach from the base 10.

[0044] In some embodiments, such as Figures 2 to 4 as well as Figure 7 As shown, the access control switch 100 also includes a second spring 50; the button 30 has a receiving cavity 32 on the side facing the base 10, the first spring 40 is partially disposed in the receiving cavity 32, the receiving cavity 32 is provided with a positioning post 33 extending toward the micro switch 20, the first end of the second spring 50 is sleeved on the positioning post 33, and the second end of the second spring 50 abuts against the micro switch 20.

[0045] Specifically, one end of the first spring 40 is fitted into the receiving cavity 32 of the button 30, and the other end of the first spring 40 is adapted to the shape and size of the first groove 11 so that the first spring 40 is tightly fitted into the first groove 11, thereby preventing the first spring 40 from loosening during compression deformation.

[0046] In this embodiment, the first end of the second spring 50 is sleeved on the positioning post 33 to prevent the second spring 50 from becoming loose, and the second end of the second spring 50 abuts against the micro switch 20. When the button 30 is pressed, the button 30 moves towards the base 10, causing the second spring 50 to compress and deform. The second spring 50 then triggers the micro switch 20, causing the micro switch 20 to output a corresponding command. When the button 30 is released, both the first spring 40 and the second spring 50 return to their original shapes. The first spring 40 is a large spring, and the second spring 50 is a small spring; the first spring 40 is sleeved around the outer periphery of the second spring 50.

[0047] In some embodiments, such as Figures 2 to 4 As shown, the access control switch 100 also includes a spring retainer 60, and the second spring 50 is at least partially sleeved on the spring retainer 60, with the spring retainer 60 abutting against the micro switch 20.

[0048] Specifically, when button 30 is pressed, button 30 moves towards the base 10, the second spring 50 is compressed and deformed, and pushes the spring retainer 60 to abut against the micro switch 20, so that the spring retainer 60 touches the component on the micro switch 20. The spring retainer 60 is used to increase the elasticity and feel when button 30 is pressed, thereby improving the operating experience of the access control switch 100.

[0049] During installation, first assemble and secure the micro switch 20 in the second slot 12, then attach the second spring 50 to the positioning post 33 of the button 30, then assemble the spring pressure piece 60 and apply a pressing force to the second spring 50, and then snap each of the hooks 31 on the button 30 into the corresponding slots 13 on the base 10 to complete the assembly and fixation of the button 30 on the base 10, thereby preventing the first spring 40 and the second spring 50 from coming off.

[0050] In some embodiments, such as Figure 8 As shown, the spring compression member 60 includes a limiting platform 61 and a limiting post 62 connected to the limiting platform 61. The limiting post 62 extends toward the positioning post 33. The second spring 50 is sleeved on the limiting post 62 and abuts against the limiting platform 61. The limiting platform 61 abuts against the micro switch 20.

[0051] Specifically, when the second spring 50 is compressed and pushes the spring pressure member 60, the second spring 50 pushes against the limiting platform 61 along the limiting post 62, so that the limiting platform 61 actuates the micro switch 20. The outer diameter of the limiting platform 61 is larger than the outer diameter of the limiting post 62. The limiting platform 61 limits the second spring 50 and prevents the second spring 50 from detaching from the limiting post 62.

[0052] In some embodiments, such as Figure 6 and Figure 7As shown, the first groove 11 has four slots 13, which are equally spaced around the outer periphery of the second groove 12; the button 30 has four hooks 31, which are equally spaced around the outer periphery of the button 30.

[0053] When installing button 30, press the four hooks 31 from the outer periphery of button 30 toward the center of button 30 so that the four hooks 31 are snapped into the four slots 13 one by one. Then, release the applied pressure and the four hooks 31 will return to their shape, thus forming a snap connection with the four slots 13.

[0054] When disassembling button 30, press the four latches 31 from the outer periphery of button 30 towards the center of button 30, and push the four latches 31 from the inside out to separate button 30 from base 10. This simple disassembly method can improve disassembly and assembly efficiency.

[0055] In some embodiments, such as Figure 4 and Figure 7 As shown, the hook 31 and the button 30 are integrally formed. For example, the hook 31 and the button 30 can be injection molded.

[0056] In some embodiments, such as Figure 4 , Figure 6 as well as Figure 9 As shown, the base 10 includes an upper shell 14 and a lower shell 15, which are assembled together to form a mounting cavity. A first groove 11 is disposed on the upper shell 14. A first side plate 16 and a second side plate 17 extending into the mounting cavity are provided on opposite sides of the second groove 12. A protrusion 18 is provided on the side of the first side plate 16 facing the second side plate 17 and the side of the second side plate 17 facing the first side plate 16. A groove 21 corresponding to each protrusion 18 is provided on the micro switch 20. Each protrusion 18 is embedded in each groove 21. The protrusion 18 can be deformed under external force to disengage from the groove 21.

[0057] Specifically, the upper shell 14 and the lower shell 15 can be assembled and fixed by means of detachable methods such as screws or clips, and this embodiment does not impose specific limitations. Among them, the lower shell 15 is a shell that is installed on the wall.

[0058] In this embodiment, the second groove 12 has a first side plate 16 and a second side plate 17 extending into the mounting cavity on opposite sides, and the first side plate 16 and the second side plate 17 together form the second groove 12. When the micro switch 20 is assembled in the second groove 12, the first side plate 16 and the second side plate 17 can lock the micro switch 20 in place. The protrusions 18 on the first side plate 16 and the second side plate 17 are embedded in the grooves 21 on the micro switch 20, forming a positioning and fixing function, preventing the micro switch 20 from displacing, loosening or falling out during the pushing process, and improving the reliability of the access control switch 100.

[0059] Furthermore, the protrusion 18 can deform under external force to disengage from the groove 21, thereby allowing the micro switch 20 to be pushed out of the second groove 12 under external force, so as to facilitate the disassembly or replacement of the micro switch 20.

[0060] In some embodiments, the first side plate 16 and the second side plate 17 may be moved away from each other under the action of external force, so that the protrusion 18 is disengaged from the groove 21, and the micro switch 20 may be pushed out of the second groove 12 under the action of external force, so as to facilitate the disassembly or replacement of the micro switch 20.

[0061] In some embodiments, such as Figure 4 As shown, the inner wall of the lower shell 15 is provided with reinforcing ribs 19, which are formed on the inner edge of the lower shell 15 to enhance the structural strength of the lower shell 15.

[0062] Specifically, the reinforcing rib 19 is integrally formed on the inner edge of the lower shell 15 to enhance the structural strength of the lower shell 15 and prevent deformation or damage when the base 10 is installed on the wall.
