Description

Technical Field

[0001] This utility model relates to the field of switch protection technology, and in particular to a protective device for preventing accidental touch control switches. Background Technology

[0002] With the rapid development of electronic information technology, touch switches have been widely used in many fields such as smart homes, industrial control, medical equipment, and consumer electronics due to their advantages such as convenient operation, rapid response, and simple appearance.

[0003] However, in practical applications, the problem of accidental touches on touch switches has become increasingly prominent, causing numerous inconveniences and even safety hazards for users. Because touch switches typically use capacitive or resistive sensing principles for triggering, their sensing areas are often exposed and easily affected by external factors. For example, in a home environment, children may touch wall-mounted touch switches out of curiosity, causing lights to suddenly turn on or off. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a protective device for preventing accidental touch of a touch switch, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a protective device for preventing accidental touch of a touch switch, including a protective housing. A resistive touch switch is fixedly connected to the center of one side of the inner wall of the protective housing. A blocking flange is fixedly connected to the inner wall of the protective housing near the edge of the opening. A pressure plate is slidably connected to the inner wall of the protective housing. The size of the pressure plate is larger than the size of the inner wall of the blocking flange. A connecting groove is formed at the center of the bottom surface of the pressure plate. A guide hole is formed at the center of the bottom of the inner wall of the connecting groove. A latch is formed on the side of the inner wall of the protective housing near the guide hole. The inner wall of the guide hole slides... A locking pin is connected, the diameter of which matches the diameter of the latch, and the position of the locking pin corresponds to the position of the latch. A thrust spring is provided between the end of the locking pin away from the latch and the end of the guide hole inner wall. A connecting strip is fixedly connected to the outside of the locking pin, and the connecting strip is slidably connected to the connecting groove. A push plate is fixedly connected to the outside of the connecting strip, and the push plate is in contact with the outer surface of the pressure plate. Support springs are fixedly connected to the four corners of the side of the pressure plate near the inner wall of the protective shell, and one end of the support spring is pressed against the inner wall of the protective shell. The side of the pressure plate near the inner wall of the protective shell is in contact with the surface of the resistive touch switch.

[0006] Preferably, in any of the above schemes, the length of the locking pin and the length of the thrust spring after full compression are less than the length of the guide hole, and the length by which the thrust spring pushes one end of the locking pin out of the guide hole after resetting is greater than the depth of the locking slot.

[0007] The technical effect achieved by adopting the above solution is that the thrust spring can press the locking pin into the guide hole, thereby improving the stability of the fixation.

[0008] Preferably, in any of the above solutions, the end of the guide hole away from the bayonet coincides with the top of the connecting groove, the length of the connecting groove is greater than the length of the connecting strip, and the top of the connecting strip coincides with the top of the locking pin.

[0009] The technical effect achieved by adopting the above solution is that the top of the connecting strip and the locking pin can slide synchronously and maintain the same sliding space.

[0010] Preferably, in any of the above solutions, the width of the push plate is greater than the vertical length of the connecting groove, the horizontal length of the push plate is adapted to the width of the pressure plate, and the push plate covers the connecting groove throughout the entire stroke of the locking pin when it is engaged or pulled out.

[0011] The technical effect achieved by adopting the above solution is that by using this solution, the push plate can cover the internal structure of the protective connection groove, preventing children's fingers from being inserted and improving safety.

[0012] Preferably, in any of the above schemes, the length of the support spring after reset is greater than the depth of the protective shell, and the four support springs are arranged symmetrically to each other.

[0013] The technical effect achieved by adopting the above solution is that the support spring can be pressed against the pressure plate, thus providing stable support.

[0014] This utility model has the following advantages:

[0015] 1. This anti-accidental touch switch protection device applies pressure to the resistive touch switch by pushing the pressure plate to achieve touch operation. However, when pressing, the push plate must be pushed up first to drive the locking pin out of the slot to unlock it. Only then can the pressure plate be pushed. This opening method can effectively prevent children from accidentally pressing and pushing the switch, thus improving the protection effect and avoiding damage caused by children repeatedly pressing the switch, thereby increasing its service life.

[0016] 2. This anti-accidental touch switch protection device opens and closes by pushing the push plate upwards and then pressing it, which conforms to the user's operating habits, reduces the impact of unlocking operations, improves opening and closing efficiency, makes the entire opening and closing operation smoother, and improves the ease of use.

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figures 1 to 3 As shown, a protective device for preventing accidental touch of a touch switch includes a protective housing 1. A resistive touch switch 5 is fixedly connected to the center of one side of the inner wall of the protective housing 1. A blocking flange 12 is fixedly connected to the inner wall of the protective housing 1 near the edge of the opening. A pressure plate 3 is slidably connected to the inner wall of the protective housing 1. The size of the pressure plate 3 is larger than the size of the inner wall of the blocking flange 12. A connecting groove 9 is formed at the center of the bottom surface of the pressure plate 3. A guide hole 8 is formed at the center of the bottom of the inner wall of the connecting groove 9. A latch 7 is formed on the side of the inner wall of the protective housing 1 near the guide hole 8. A locking pin 14 is slidably connected to the inner wall of the guide hole 8. The diameter of the locking pin 14 is... The diameter of the bayonet 7 is matched, and the position of the locking pin 14 corresponds to the position of the bayonet 7. A thrust spring 11 is provided between the end of the locking pin 14 away from the bayonet 7 and the end of the inner wall of the guide hole 8. A connecting strip 10 is fixedly connected to the outside of the locking pin 14. The connecting strip 10 is slidably connected to the connecting groove 9. A push plate 4 is fixedly connected to the outside of the connecting strip 10. The push plate 4 is attached to the outer surface of the pressure plate 3. Support springs 13 are fixedly connected to the four corners of the side of the pressure plate 3 near the inner wall of the protective shell 1. One end of the support spring 13 is pressed against the inner wall of the protective shell 1. The side of the pressure plate 3 near the inner wall of the protective shell 1 is attached to the surface of the resistive touch switch 5.

[0023] As an optional technical solution of this utility model, the length of the locking pin 14 and the length of the thrust spring 11 after full compression are less than the length of the guide hole 8. After the thrust spring 11 is reset, the length of one end of the locking pin 14 pushed out of the guide hole 8 is greater than the depth of the bayonet 7, so that the thrust spring 11 can press the locking pin 14 into the interior of the guide hole 8, thereby improving the stability of the fixation.

[0024] As an optional technical solution of this utility model, the end of the guide hole 8 away from the bayonet 7 coincides with the top of the connecting groove 9. The length of the connecting groove 9 is greater than the length of the connecting strip 10. The top of the connecting strip 10 coincides with the top of the locking pin 14, so that the top of the connecting strip 10 and the locking pin 14 slide synchronously and maintain the same sliding space.

[0025] As an optional technical solution of this utility model, the width of the push plate 4 is greater than the vertical length of the connecting groove 9, and the horizontal length of the push plate 4 is adapted to the width of the pressure plate 3. The push plate 4 covers the connecting groove 9 throughout the entire stroke of the locking pin 14 when it is engaged or pulled out, thereby covering and protecting the internal structure of the connecting groove 9, preventing children's fingers from being inserted, and improving safety.

[0026] As an optional technical solution of this utility model, the length of the support spring 13 after reset is greater than the depth of the protective shell 1, and the four support springs 13 are arranged symmetrically to each other, so that the support springs 13 can press against the contact plate 3 and provide stable support.

[0027] The following steps are required when using this anti-accidental touch switch protection device:

[0028] 1) Touch operation is achieved by applying pressure to the resistive touch switch 5 by pushing the pressure plate 3;

[0029] 2) Before pressing, the push plate 4 needs to be pushed up first to drive the latch 14 out of the latch 7 to unlock it. Only then can the push plate 3 be pushed. This opening method can effectively prevent children from accidentally pressing the push plate and causing abnormal opening and closing.

[0030] 3) After the pressing is finished and the pressure is released, the support spring 13 pushes the pressure plate 3 to reset, so that the locking pin 14 is engaged in the slot 7, realizing automatic reset and locking.

[0031] In summary, by pushing the pressure plate 3 to apply pressure to the resistive touch switch 5, touch operation is achieved. However, when pressing, the push plate 4 must first be pushed up to disengage the latch 14 from the latch 7 to unlock it before the pressure plate 3 can be pushed. This opening method effectively prevents children from accidentally pressing the switch, thus avoiding abnormal opening and closing and improving the protection effect. It also avoids damage caused by children repeatedly pressing the switch, thus extending its service life. The operation of pushing the push plate 4 up and then pressing to open and close the switch conforms to the user's operating habits, reduces the impact of unlocking operations, improves opening and closing efficiency, and makes the entire opening and closing operation smoother and more convenient to use.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
