Abstract
Description
Technical Field
[0001] This utility model relates to the field of door lock touch switch technology, specifically a bathroom door lock touch switch. Background Technology
[0002] In door lock systems with dual-panel linkage control, combining mechanical structures with circuit control to achieve door panel status monitoring and alert functions has become the mainstream design direction in the industry. Traditional designs typically use a combination of a bolt and a micro-switch; when the door is closed, the bolt slides to trigger the micro-switch, illuminating indicator lights and other functions.
[0003] However, in existing technologies, the springs used to transmit triggering force and reset within microswitches have significant defects. Because the springs are subjected to high-frequency elastic deformation over long periods, the metal material is highly susceptible to fatigue damage during repeated stretching and compression. With increased use, the springs may experience a decrease in elasticity, plastic deformation, or even breakage, leading to reduced switch triggering sensitivity, poor contact, and consequently, malfunctions such as indicator light flashing and false alarms. Utility Model Content
[0004] In view of this, the present invention provides a bathroom door lock touch switch, which aims to solve the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a bathroom door lock touch switch, comprising:
[0006] The first door panel is fixedly installed, and a second door panel that can be opened and closed is provided parallel to one side of the first door panel. A first lock box is fixedly installed on the first door panel, and a second lock box is fixedly installed on the second door panel. Through holes are provided on both sides of the first lock box and the second lock box.
[0007] The latch is horizontally slidably disposed in the second lock box. When the sliding component drives the latch to slide, the latch slides into or out of the first lock box through the two through holes.
[0008] A lifting block is slidably disposed in the first lock box. A micro-control switch is provided in the first lock box below the lifting block. A pressure plate is provided on the upper end of the micro-control switch. A trigger protrusion is provided on the micro-control switch below the pressure plate. A spring piece parallel to it is provided on the pressure plate. The first wedge-shaped surface on the lifting block is adapted to the second wedge-shaped surface at the end of the lock tongue.
[0009] The first link is rotatably located in the first lock box. Its first end is connected to the end of the spring piece through a connecting component. The second end of the first link is fixed with a counterweight. When the spring piece returns to its original position, the counterweight drives the spring piece to return to its original position through the connecting component.
[0010] A further improvement of this utility model is that the connecting assembly includes a connecting rod fixedly disposed at the end of the spring piece, and a guide post is fixedly disposed at the upper end of the connecting rod, and the guide post is slidably connected to the elongated slot hole on the first end of the first connecting rod.
[0011] A further improvement of this utility model is that the sliding assembly includes a first rotating shaft, which is mounted inside the second lock box. A first gear fixed at the first end of the first rotating shaft meshes with a rack horizontally fixed on the lock tongue. A rotating wheel is fixed at the second end of the first rotating shaft after passing through the second lock box.
[0012] A further improvement of this utility model is that an anti-rotation component is provided on the first rotating shaft, and a release component is provided on one side of the anti-rotation component.
[0013] A further improvement of this utility model is that the anti-rotation component includes:
[0014] A ratchet is fixedly mounted on the first rotating shaft;
[0015] The pawl is rotatably mounted in the second lock box. Its first end is adapted to the ratchet. A spring is provided on the lower surface of the second end of the pawl. The lower end of the spring is connected to the mounting plate in the second lock box.
[0016] A further improvement of this utility model is that the release component includes a screw, which is disposed on the second lock box. The upper end of the screw is threadedly connected to the top of the second lock box and a handwheel is fixed therethrough. The lower end of the screw is disposed opposite to the second end of the pawl.
[0017] A further improvement of this utility model is that a baffle is fixedly provided inside the first lock box, and the baffle is located above the side of the lifting block away from the through hole.
[0018] A further improvement of this utility model is that the micro-control switch is electrically connected to the signal transmitter, and a signal receiver is provided at the power supply of the indicator light, and the signal receiver is electrically connected to the indicator light power switch controller.
[0019] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:
[0020] This utility model provides a bathroom door lock touch switch. By setting a counterweight at the end of the first linkage and utilizing its linkage and reset mechanism with the spring, the burden on the spring's own elastic reset is reduced, and the risk of fatigue damage caused by high-frequency elastic deformation of the spring is lowered. Compared with the prior art, when the latch triggers the spring to move, the gravity of the counterweight can assist the spring to reset quickly and stably, avoiding the spring from being in a state of stress and deformation for a long time, thereby extending the service life of the spring and ensuring the long-term reliability of the micro-control switch trigger.
[0021] In this invention, the matching design of the first and second wedge surfaces allows the locking tongue to precisely and smoothly push the lifting block during sliding, thereby reliably triggering the micro-control switch. Compared to traditional structures where triggering failure may occur due to component wear, this solution, through the guidance and transmission of the wedge surfaces, ensures that the locking tongue can stably press the pressure plate and spring when sliding into or out of the first lock box, improving the sensitivity and stability of the switch triggering.

[0031] This utility model provides a bathroom door lock touch switch, as detailed in the attached instruction manual. Figure 1 To be continued Figure 5 It can be seen that a bathroom door lock touch switch mainly includes the following parts or components: first door panel 10, lock tongue 121, lifting block 131, and first connecting rod 14.
[0032] In this utility model, a first door panel 10 is fixedly installed, and a second door panel 11 that can be opened and closed is provided parallel to one side of the first door panel 10. A first lock box 12 is fixedly installed on the first door panel 10, and a second lock box 13 is fixedly installed on the second door panel 11. Through holes 111 are provided on both sides of the first lock box 12 and the second lock box 13. The lock tongue 121 is horizontally slidably installed in the second lock box 13. When the sliding component 30 drives the lock tongue 121 to slide, the lock tongue 121 slides into or out of the first lock box 12 through the two through holes 111. A lifting block 131 is slidably installed in the first lock box 12. A micro-control switch 132 is provided in the first lock box 12 below the lifting block 131. A pressure plate 134 is provided at the upper end of the locking mechanism 132. A trigger protrusion 133 is provided on the micro-control switch 132 below the pressure plate 134. A spring piece 135 parallel to the pressure plate 134 is provided on the pressure plate 134. The first wedge-shaped surface 123 on the lifting block 131 is adapted to the second wedge-shaped surface 122 at the end of the locking tongue 121. The middle part of the first connecting rod 14 is rotatably disposed in the first lock box 12. Its first end is connected to the end of the spring piece 135 through the connecting assembly 20. A counterweight 141 is fixedly provided at the second end of the first connecting rod 14. When the spring piece 135 returns to its original position, the counterweight 141 drives the spring piece 135 to return to its original position through the connecting assembly 20. The connecting assembly 20 includes a connecting rod 21, which is fixedly disposed at the end of the spring piece 135. A guide post 22 is fixedly provided at the upper end of the connecting rod 21. The guide post 22 is slidably connected to the elongated slot 142 on the first end of the first connecting rod 14.
[0033] When the second door panel 11 approaches and closes towards the first door panel 10, the sliding assembly 30 drives the latch 121 to slide horizontally within the second lock box 13. The latch 121 extends out from the through hole 111 of the second lock box 13, passes through the through hole 111 of the first lock box 12, and enters it. During this process, the second wedge-shaped surface 122 at the end of the latch 121 contacts the first wedge-shaped surface 123 on the lifting block 131. Due to the guiding effect of the first wedge-shaped surface 123 and the second wedge-shaped surface 122, the horizontal thrust of the latch 121... This pressure is converted into a vertical downward force on the lifting block 131, pushing it down into the first lock box 12. As the lifting block 131 slides down, its bottom gradually approaches and presses against the spring piece 135. The deformation of the spring piece 135 allows the pressure plate 134 to accurately press the trigger protrusion 133 on the micro-control switch 132, triggering the micro-control switch 132 to activate the circuit. When the spring piece 135 deforms, the first connecting rod 14, which is connected to the end of the spring piece 135 via the connecting assembly 20, begins to move. The connecting rod 21 in the connecting assembly 20 moves with the spring piece 135, and the guide post 22 at its upper end slides in the long slot 142 at the first end of the first connecting rod 14, causing the first connecting rod 14 to rotate around its middle fulcrum. The counterweight 141 at the second end is lifted, increasing the gravitational potential energy and accumulating force for the subsequent reset of the spring piece 135.
[0034] When the second door panel 11 needs to be opened, the sliding assembly 30 reverses the driving force of the latch 121, causing it to retract from the through hole 111 of the first lock box 12 into the second lock box 13. As the latch 121 retracts, the second wedge-shaped surface 122 at the end of the latch 121 disengages from the first wedge-shaped surface 123 of the lifting block 131, and the vertical pressure on the lifting block 131 disappears. At this time, under the gravity of the counterweight 141 at the second end of the first connecting rod 14, the first connecting rod 14 rotates in the opposite direction around the central fulcrum. Through the guide post 22 of the connecting assembly 20 and the long slot 142, the connecting rod 21 is pulled, which in turn drives the spring 135 to reset. Due to the stable driving force provided by the counterweight 141, the spring 135 can quickly and reliably return to its initial position, while driving the pressure plate 134 to move upward, so that the trigger protrusion 133 of the micro-control switch 132 is no longer pressed, and the circuit is disconnected. During the reset process of the spring 135, the spring 135 drives the lifting block 131 to slide upward and return to the initial position in the first lock box 12, preparing for the triggering when the door panel closes again.
[0035] By setting a counterweight 141 at the end of the first link 14 and utilizing its linkage reset mechanism with the spring 135, the burden of the spring 135's own elastic reset is reduced, and the risk of fatigue damage caused by high-frequency elastic deformation of the spring 135 is reduced. Compared with the prior art, when the locking tongue 121 triggers the action of the spring 135, the gravity of the counterweight 141 can assist the spring 135 to reset quickly and stably, avoiding the spring 135 from being in a state of stress deformation for a long time, thereby extending the service life of the spring 135 and ensuring the long-term reliability of the micro-control switch 132 trigger.
[0036] Specifically, during long-term use, the pressure plate 134 may wear due to friction, leading to changes in the triggering force. The elasticity of the spring 135 can dynamically compensate for this wear, maintain the consistency of the switch triggering force, and extend the switch life.
[0037] As one embodiment, in conjunction with the appendix to the specification Figure 4 As can be seen, the sliding assembly 30 includes a first rotating shaft 31, which is mounted inside the second lock box 13. A first gear 32 fixed at the first end of the first rotating shaft 31 meshes with a rack 33 horizontally fixed on the latch 121. A rotating wheel (not shown in the figure) is fixed at the second end of the first rotating shaft 31 after passing through the second lock box 13. Rotating the rotating wheel can cause the first rotating shaft 31 to rotate, which drives the first gear 32 to rotate. The first gear 32 drives the rack 33 to move horizontally, and the rack 33 drives the latch 121 to slide into or out of the first lock box 12 through the two through holes 111.
[0038] As one embodiment, in conjunction with the appendix to the specification Figure 5 It is known that an anti-rotation component 40 is provided on the first rotating shaft 31, and a release component is provided on one side of the anti-rotation component 40. The anti-rotation component 40 includes a ratchet 41, which is fixed on the first rotating shaft 31; a pawl 42 is rotatably disposed in the middle of the second lock box 13, with its first end adapted to the ratchet 41, and a spring 421 provided on the lower surface of the second end of the pawl 42, the lower end of the spring 421 being connected to the mounting plate 422 inside the second lock box 13. The release component includes a screw 15, which is disposed on the second lock box 13, with the upper end of the screw 15 threadedly connected to the top of the second lock box 13 and a handwheel 151 fixed thereafter, and the lower end of the screw 15 being disposed opposite to the second end of the pawl 42.
[0039] After the door is closed, the rotating wheel is turned, which drives the first rotating shaft 31 to rotate. At the same time, the ratchet 41 is also rotating. After the first rotating wheel stops rotating, the pawl 42 is lifted by the action of the spring 421, and the locking tooth at its first end is engaged in the ratchet tooth gap of the ratchet 41 to form a one-way lock, thereby preventing the bolt 121 from being accidentally retracted due to collision, accidental contact, etc.
[0040] When the door needs to be opened, turn the handwheel 151. The handwheel 151 drives the screw 15 to rotate. The screw 15 descends and the lower end of the screw 15 presses down on the second end of the pawl 42. The second spring 421 contracts. At this time, the first end of the pawl 42 disengages from the ratchet 41, and the first rotating shaft 31 can be rotated. The first rotating shaft 31 can retract the latch 121 through the cooperation of the first gear 32 and the rack 33.
[0041] As one embodiment, in conjunction with the appendix to the specification Figure 2 It is known that a baffle 16 is fixedly installed inside the first lock box 12, and the baffle 16 is located above the side of the lifting block 131 away from the through hole 111.
[0042] Although the stop block is located above the lifting block 131, it does not interfere with the lifting block 131. The purpose of the stop block is to block the locking tongue 121. That is, after the locking tongue 121 has completely pressed down the lifting block 131, the locking tongue 121 will not move forward under the action of the stop block.
[0043] As one embodiment, in conjunction with the appendix to the specification Figure 2 It can be seen that the micro-control switch 132 is electrically connected to the signal transmitter 17, and a signal receiver (not shown in the figure) is provided at the power supply of the indicator light (not shown in the figure), and the signal receiver is electrically connected to the indicator light power switch controller (not shown in the figure).
[0044] When the micro switch is triggered, it sends a signal to the signal receiver via the signal transmitter 17, turning on the indicator light power switch controller and supplying power to the indicator light so that it lights up.
[0045] When the micro switch is turned off, the signal stops, the indicator light power switch controller turns off, and the indicator light turns off.
