Description
Technical Field
[0001] The utility model relates to the technical field of solenoid valve locks, in particular to a solenoid valve lock with shock absorption and noise reduction effects. Background Technique
[0002] Solenoid valves have the advantages of high-precision control, stable operation, fast response, etc., and are favored by the door lock manufacturing industry. Doors controlled by solenoid valves have the advantage of being convenient for locking and unlocking. They can be locked or unlocked without manual operation, bringing convenience to people's lives.
[0003] However, in the prior art, when traditional solenoid valve locks are in use, there are problems such as too much noise when the solenoid valve controls the collision between the lock tongue and the metal card slot, no shock absorption, poor protection effect, and easy occurrence of tongue jamming. Often, due to tongue jamming, it is impossible to open the door, and the noise is too loud, which affects people's rest when someone opens or closes the door during rest. Content of the Utility Model

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A solenoid valve lock with shock absorption and noise reduction effects, including a lock body, a lock tongue, and a door frame. A lock core is embedded on the surface of the lock body, and a key is inserted into the lock core to open the door. A fixed plate is fixedly installed on the rear surface of the lock core. One side of the fixed plate is movably connected to a cylinder. An air pipe is fixedly installed on the top of the cylinder. A two-position five-way solenoid valve is fixedly installed on one side of the air pipe. The gas inside the two-position five-way solenoid valve is driven into the cylinder through the air pipe. A first spring is fixedly installed on the right surface of the cylinder. One side of the first spring is fixedly connected to a lead screw. The center of the lead screw is movably connected to a screw disk. A second spring is fixedly installed on one side of the screw disk.
[0006] The technical effect of adopting the above further scheme is: By driving the cylinder with the two-position five-way solenoid valve, while achieving the telescopic movement, the lock tongue can move slowly in the lock body.
[0007] As a preferred implementation manner, when the screw disk receives the pulling force brought by the first spring, the screw disk rotates and moves on the lead screw, thereby driving the second spring to tighten. When the pulling force brought by the first spring on the screw disk disappears, it rotates and moves to the left on the lead screw, thereby driving the second spring to relax.
[0008] The technical effects of adopting the above further scheme are as follows: When the locking tongue is tightened by the rotation of the screw disc, it will achieve a shock-absorbing effect on the movement of the locking tongue. When the locking tongue is relaxed, it will slowly return to the card slot inside the door frame, achieving the effect of reducing noise.
[0009] As a preferred embodiment, a disc is movably installed on the rear surface of the fixing plate, and a crank rocker is movably connected to the top of the disc. The rotation of the disc drives the crank rocker to rotate.
[0010] The technical effects of adopting the above further scheme are as follows: When unlocking, the rotation of the lock core drives the rotation of the disc, thereby driving the rotation of the crank rocker.
[0011] As a preferred embodiment, a connecting rod is fixedly connected to one side of the crank rocker, a crankshaft is fixedly connected to one side of the connecting rod. The connecting rod plays a connecting role between the crank rocker and the crankshaft, and a slider is connected to the lower surface of the crankshaft.
[0012] The technical effects of adopting the above further scheme are as follows: When the crank rocker and the disc rotate, they drive the connecting rod and the crankshaft on one side of the connecting rod to move together.
[0013] As a preferred embodiment, the slider moves left and right with the movement of the crankshaft, and a push rod is fixedly installed inside the slider.
[0014] The technical effects of adopting the above further scheme are as follows: The slider will move left and right due to the force brought by the crankshaft.
[0015] As a preferred embodiment, a round handle is fixedly installed on one side of the push rod, an oil barrel is fixedly installed on one side of the round handle, and the push of the push rod drives the round handle to push the oil barrel.
[0016] The technical effects of adopting the above further scheme are as follows: The movement of the slider drives the forward push of the push rod, so that the round handle squeezes the oil barrel.
[0017] As a preferred embodiment, a pipeline is fixedly installed on one side of the oil barrel, a nozzle is fixedly connected to one side of the pipeline. The liquid in the oil barrel is conveyed to the nozzle through the pipeline and flows onto the locking tongue, making the surface of the locking tongue fully saturated with the liquid.
[0018] The technical effects of adopting the above further scheme are as follows: When the oil barrel is squeezed, the lubricating oil emerging from the opening of the oil barrel is conveyed to the nozzle through the pipeline and sprayed onto the surface of the locking tongue to soak it.
[0019] As a preferred embodiment, a card slot is embedded inside the door frame, and a rubber strip is embedded on the inner surface of the card slot.
[0020] The technical effect of adopting the above further solution is that when the rubber strip moves with the arrival of the lock tongue, it fully alleviates the impact force brought by the lock tongue. When the lock tongue returns to the card slot, it is surrounded by the rubber strip, increasing the friction force and reducing the noise.
[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:
[0022] 1. In the present utility model, when the two-position five-way solenoid valve is opened and the key is inserted into the lock core, the lock core rotates to drive the rotation inside the fixed plate to apply a force to the inside of the cylinder. The two-position five-way solenoid valve drives the gas inside through the air pipe to the cylinder. The cylinder is pulled to the left by the gas to tighten the spring one. The spring one drives the screw rod to move to the left to tighten the lock tongue. At the same time, the spiral disc rotates on the screw rod when tightening, and a buffering and tightening effect is carried out by squeezing the spring two, achieving a shock-absorbing effect on the lock tongue and reducing noise.
[0023] 2. In the present utility model, when the lock core rotates, the lock core also drives the rotation of the disc. The rotation of the disc drives the crank rocker on its top and the connecting rod connecting the crank shaft. The rotational movement of the crank rocker is brought to the crank shaft to push the slider to move left and right. The slider applies a force to the push rod to the right, which is given to the round handle to push the oil barrel. The oil barrel is pushed, and the lubricating oil inside it comes out and is conveyed to the nozzle through the oil pipe to drip oil on the lock tongue, so as to prevent the situation of stuck tongue from occurring.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0031] Please refer to Figures 1-4 , the present invention provides a technical solution: a solenoid valve lock with shock absorption and noise reduction effects, including a lock body 1, a lock tongue 2, and a door frame 3. A lock core 101 is embedded on the surface of the lock body 1, and a key is inserted into the lock core 101 for door opening activities. A fixed plate 102 is fixedly installed on the rear surface of the lock core 101. One side of the fixed plate 102 is movably connected to a cylinder 201. An air pipe 202 is fixedly installed on the top of the cylinder 201. A two-position five-way solenoid valve 203 is fixedly installed on one side of the air pipe 202. The gas in the two-position five-way solenoid valve 203 is driven into the cylinder 201 through the air pipe 202. A spring 1 204 is fixedly installed on the right surface of the cylinder 201. One side of the spring 1 204 is fixedly connected to a screw rod 205. The center of the screw rod 205 is movably connected to a screw disc 206. A spring 2 207 is fixedly installed on one side of the screw disc 206. By driving the cylinder 201 through the two-position five-way solenoid valve 203, while achieving the telescopic movement, the lock tongue 2 can slowly move in the lock body 1.
[0032] As Figures 1-4 shown, the screw disc 206 receives the pulling force brought by the spring 1 204, and the screw disc 206 rotates and moves on the screw rod 205 to drive the spring 2 207 to tighten. When the pulling force brought by the spring 1 204 on the screw disc 206 disappears, it rotates and moves to the left on the screw rod 205 to drive the spring 2 207 to relax, so that the moving speed of the lock tongue 2 reaches a great buffering effect. When the lock tongue passes through the rotation of the screw disc 206 and tightens the lock tongue 2, it will achieve a shock absorption effect on the movement of the lock tongue 2. When the lock tongue 2 is relaxed, it will slowly return to the card slot 301 in the door frame 3 to achieve the effect of reducing noise.
[0033] As Figures 1-4 shown, a disc 103 is movably installed on the rear surface of the fixing plate 102. A crank rocker 104 is movably connected to the top of the disc 103. The rotation of the disc 103 drives the crank rocker 104 to rotate. When unlocking, the lock core 101 drives the rotation of the disc 103, thereby driving the rotation of the crank rocker 104.
[0034] As Figures 1-4 shown, a connecting rod 105 is fixedly connected to one side of the crank rocker 104. A crankshaft 106 is fixedly connected to one side of the connecting rod 105. The connecting rod 105 plays a connecting role between the crank rocker 104 and the crankshaft 106. The lower surface of the crankshaft 106 is connected to a slider 107. When the crank rocker 104 and the disc 103 rotate, they drive the connecting rod 105 and the crankshaft 106 on one side of the connecting rod 105 to move together.
[0035] As Figures 1-4 shown, the slider 107 moves left and right with the movement of the crankshaft 106. A push rod 108 is fixedly installed inside the slider 107. The slider 107 will move left and right due to the force brought by the crankshaft 106.
[0036] As Figures 1-4 shown, a round handle 109 is fixedly installed on one side of the push rod 108. An oil barrel 110 is fixedly installed on one side of the round handle 109. The push of the push rod 108 drives the round handle 109 to push the oil barrel 110. The movement of the slider 107 drives the forward push of the push rod 108, so that the round handle 109 squeezes the oil barrel 110.
[0037] As Figures 1-4 shown, a tubing 111 is fixedly installed on one side of the oil barrel 110. A nozzle 112 is fixedly connected to one side of the tubing 111. The liquid inside the oil barrel 110 is conveyed to the nozzle 112 through the tubing 111 and flows onto the lock tongue 2, making the surface of the lock tongue 2 fully saturated with the liquid. When the oil barrel 110 is squeezed, the lubricating oil emerging from the opening of the oil barrel 110 is conveyed into the nozzle 112 through the tubing 111 and sprayed onto the surface of the lock tongue 2 to soak it.
[0038] As Figures 1-4 shown, a card slot 301 is embedded inside the door frame 3. A rubber strip 302 is embedded on the inner surface of the card slot 301. When the lock tongue 2 moves, the rubber strip 302 fully alleviates the impact force brought by the lock tongue 2. When the lock tongue 2 returns into the card slot 301, it is surrounded by the rubber strip 302, increasing the friction force and reducing the noise.
[0039] Working principle: This device is a solenoid valve lock with shock absorption and noise reduction effects. When in use, the two-position five-way solenoid valve 203 is opened, and the key is inserted into the lock core 101. The lock core 101 rotates to drive the rotation inside the fixing plate 102 to apply a force inside the cylinder 201. The two-position five-way solenoid valve 203 drives the internal gas through the air pipe 202 into the cylinder 201. The cylinder 201 is pulled to the left by the gas to tighten the first spring 204. The first spring 204 drives the lead screw 205 to move to the left to tighten the lock tongue 2. At the same time, the spiral disc 206 rotates on the lead screw 205 during tightening, and a buffering and tightening effect is achieved by squeezing the second spring 207, so as to achieve the shock absorption effect on the lock tongue 2 and reduce noise. While the lock core 101 rotates, the lock core 101 also drives the rotation of the disc 103. The rotation of the disc 103 drives the crank rocker 104 fixedly installed on its top and the connecting rod 105 connecting the crankshaft 106. The rotational movement of the crank rocker 104 drives the crankshaft 106 to push the slider 107 to move left and right. The slider 107 pushes the push rod 108 to move to the right, giving the round handle 109 to push the oil barrel 110, so that the oil in the oil barrel 110 overflows. The overflowing lubricating oil is conveyed to the nozzle 112 through the oil pipe 111 to drip oil on the lock tongue 2, so that the lock tongue 2 will not cause the situation of stuck tongue. When the key is turned back to the original position of the lock tongue 2, all the devices change from pulling force to the right to relaxing to the left. At the same time, the lock tongue 2 rotates in the opposite direction of the spiral disc 206 and slowly returns to the card slot 301 on the lead screw 205, and the rebound noise is reduced by contacting the rubber strip 302. It solves the problems that when the traditional solenoid valve lock is in use, there is too much collision noise between the solenoid valve controlling the lock tongue of the door lock and the metal card slot 301, there is no shock absorption, the protection effect is poor, the situation of stuck tongue is likely to occur, and often the door cannot be opened due to the stuck tongue, the sound noise is too large, and when someone opens or closes the door during rest, it affects people's rest.
[0040] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
