Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figure 1-7 , the present utility model provides a technical solution: a quick-release tactile switch that is convenient for maintenance and replacement, including a tactile switch body 1, a back plate 2, a mounting bracket 3, a support block 4, a fixed pressing plate 5, a positioning pin 6, a protective frame 7, a sealing gasket 8, an anti-misoperation baffle 9, a fixing block 10, a connecting mechanism 11, a connecting block 12, a spring 13, a connecting rod 14, a locking rod 15, a movable sleeve 16, and a fixed pull rod 17.

[0035] When using this quick-release tactile switch that is convenient for maintenance and replacement, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, an installation bracket 3 is provided on the front side of the backplane 2, and support blocks 4 are provided on both the left and right sides above the installation bracket 3. At the same time, the support block 4 is hinged to the fixed pressing plate 5, and a first torsion spring is provided at the connection between the support block 4 and the fixed pressing plate 5. By flipping the fixed pressing plate 5, the fixed pressing plate 5 rotates with the support block 4, and at this time, the first torsion spring undergoes elastic deformation. Then, the card slot of the tactile switch body 1 is installed in the installation bracket 3, and then the fixed pressing plate 5 is directly released. At this time, the first torsion spring restores its elastic deformation, driving the fixed pressing plate 5 to flip, so that the fixed pressing plate 5 is attached to the upper end of the tactile switch body 1. Then, the positioning pin 6 is inserted into the fixed pressing plate 5 and the support block 4, which is convenient for locking between the fixed pressing plate 5 and the support block 4, completing the installation and fixation of the tactile switch body 1. The disassembly and assembly operations are relatively convenient, facilitating maintenance and replacement;

[0036] As Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in the figure, then the protection frame 7 is bolted to the backplane 2, and a gasket 8 is provided between the protection frame 7 and the backplane 2. Through the setting of the gasket 8, the sealing effect of the connection can be improved, which can play a waterproof role to a certain extent, preventing water stains from entering the connection and damaging the tactile switch body 1. At the same time, an anti-misoperation baffle 9 is attached to the front side of the protection frame 7. Through the settings of the protection frame 7 and the anti-misoperation baffle 9, it can prevent the tactile switch body 1 from being misoperated when not in use, and the protection effect is good. Moreover, in combination with the setting of the connection mechanism 11, the connection mechanism 11 is symmetrically arranged on both the left and right sides of the upper end of the protection frame 7. At the same time, the connection mechanism 11 includes connection blocks 12 fixedly connected to both the left and right sides of the upper end of the protection frame 7, springs 13 arranged inside the connection blocks 12, connecting rods 14 fixedly connected to the movable ends of the springs 13, locking rods 15 for limiting, movable sleeves 16 rotatably connected to the side of the connecting rod 14 close to the vertical central axis of the protection frame 7, and fixed pull rods 17 fixedly connected to the sides of the movable sleeves 16;

[0037] First, by pulling the fixed pull rod 17 upward, the fixed pull rod 17 drives the rotation between the movable sleeve 16 and the connecting rod 14. The second torsion spring at the connection between the movable sleeve 16 and the connecting rod 14 undergoes elastic deformation, and the connecting rod 14 drives the locking rod 15 to rotate, so that the locking rod 15 faces upward and aligns with the notch at the upper end of the anti-misoperation baffle 9, thereby releasing the locking between the connecting rod 14 and the anti-misoperation baffle 9. Then, pull the fixed pull rod 17 inward. The fixed pull rod 17 drives the connecting rod 14 to slide telescopically in the connecting block 12 through the movable sleeve 16. At this time, the connecting rod 14 squeezes the spring 13, causing the spring 13 to undergo elastic deformation. The connecting rod 14 moves toward the side close to the vertical central axis of the protection frame 7. The connecting rod 14 disengages from the anti-misoperation baffle 9, and the connecting rod 14 drives the locking rod 15 to move out of the notch at the upper end of the anti-misoperation baffle 9, thereby releasing the limit between the anti-misoperation baffle 9 and the protection frame 7. Then, slowly pull the anti-misoperation baffle 9 downward. The anti-misoperation baffle 9 slides with the fixed block 10, and the anti-misoperation baffle 9 is pulled open from the front side of the protection frame 7, showing a state as Figure 4 shown, and then the hand can be inserted into the protection frame 7 to operate the touch switch body 1.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
