Abstract
Description
Technical Field
[0001] This utility model relates to the field of air shower door technology, and in particular to an electronic door lock control device. Background Technology
[0002] An air shower is a versatile local purification device installed between clean and non-clean areas. When people and goods need to enter the clean area, they must pass through the air shower. The clean air blown out removes dust carried by people and goods, effectively blocking or reducing dust sources from entering the clean area. The front and rear doors of the air shower and cargo shower are electronically interlocked, also functioning as an airlock to prevent unpurified air from entering the clean area.
[0003] As the pre-structure for opening the air shower room, the electronic door lock installed on the air shower door will become stiff after long-term use due to repeated key insertions. This will not only accelerate the wear of the lock pattern inside the keyhole, but also increase the speed of key deformation, thereby reducing the key unlocking speed.
[0004] Therefore, we designed an electronic door lock control device. Utility Model Content
[0005] The purpose of this invention is to address the problem that existing technologies become sluggish after prolonged use, and to propose an electronic door lock control device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An electronic door lock control device includes a door body, a lock body on the door body, a keyhole for key insertion on the lock body, and an anti-extension body inside the lock body to prevent the key from being extended into the door.
[0008] The lock body is provided with a limiting post for restricting key insertion, and the lock body is provided with an oil tank for storing lubricating oil, and the oil tank is provided with an oil pump pipe for discharging lubricating oil.
[0009] Preferably, the limiting post is fixedly connected to the inner wall of the lock body, and the anti-extension body is fixedly connected to the lock body.
[0010] Preferably, the lock body is provided with an extension rod for contacting the front end of the key, and the extension rod abuts against the lock body. One end of the extension rod is provided with a striker, and the striker is provided with a spring.
[0011] Preferably, the extension rod is rotatably connected to the oil tank via a rotating shaft, the rotating shaft is fixedly connected to the oil tank, and the extension rod is provided with a first transmission rod.
[0012] Preferably, the first transmission rod is fixedly connected to the oil tank via a second transmission rod, the second transmission rod is fixedly connected to the first transmission rod, and the other end is fixedly connected to the oil tank.
[0013] Preferably, the oil pump pipe is fixed inside the oil storage tank by a pressure pump, the side wall of the oil storage tank is provided with a stop button, and the stop button is fixedly connected to the pressure pump. The second transmission rod is provided with a stop rod, and the stop rod is adapted to the stop button. The oil storage tank is provided with a filling pipe for inputting lubricating oil, and the extension rod is provided with multiple spray pipes for spraying lubricating oil, and the spray pipes are fixedly connected to the oil pump pipe.
[0014] The beneficial effects of this utility model are as follows:
[0015] This invention, through the setting of a first transmission rod and a second transmission rod, enables the extension rod to drive the first transmission rod to rotate under the activation of the striker, thereby improving the impact efficiency of the striker and the strike button, and thus increasing the spray diameter of the lubricating oil in the oil injection pipe. This not only masks the stiffness of the key tip, but also improves the contact effect between the key and the inner wall of the keyhole, thereby preventing the key from deforming due to the stiffness of the keyhole, and thus improving the efficiency and speed of unlocking each time.
[0016] This invention, through the setting of the rotating shaft, allows the extension rod to rotate at a 45° angle under the influence of the striking pin, thereby effectively transmitting the generated force to the oil pump pipe in the oil reservoir. This not only absorbs the force brought by the key insertion, but also increases the amount of lubricating oil drawn into the oil pump pipe, thereby improving the efficiency of the oil injection pipe in spraying lubricating oil.

[0024] Reference Figures 1-6 The electronic door lock control device includes a door body 1, which is an air shower door in the prior art, and a lock body 2, which is an electronic door lock installed on the air shower door. Due to long-term use of electronic fingerprint or facial recognition, when the electronic door lock malfunctions and the physical key is used to open the door, the key hole 3 inside the lock body 2 will become rusty and stiff, which will cause the key to deform. The anti-extension body 5 is mainly used to prevent the key from being inserted too deeply and causing scratches to the inner wall of the key hole 3.
[0025] The lock body 2 is provided with a limiting post 4 for limiting key insertion. The limiting post 4 is mainly used to limit the depth of the key. It is long and narrow. The limiting post 4 is fixedly connected to the inner wall of the lock body 2 by welding. The anti-extension body 5 is fixedly connected to the lock body 2 by welding.
[0026] The lock body 2 is provided with an extension rod 6 for contacting the front end of the key. The extension rod 6 is the main structure and also the force transmission component. The extension rod 6 abuts against the lock body 2. Under normal circumstances, the side wall of the extension rod 6 is kept in a horizontal and tight state with the inner wall of the lock body 2. One end of the extension rod 6 is provided with a striker 7. The striker 7 is existing technology. It mainly contacts the front end of the key and transmits excess force to the extension rod 6. The striker 7 is provided with a spring. The spring can increase the reaction force of the striker 7 and prevent the striker 7 from deforming due to impact.
[0027] The lock body 2 is equipped with an oil reservoir 8 for storing lubricating oil. The oil reservoir 8 is used to store metal lubricating oil and is in liquid form. The oil reservoir 8 is made entirely of aluminum alloy and is semi-open. It has an oil-repellent layer inside. The extension rod 6 is rotatably connected to the oil reservoir 8 via a rotating shaft 10. The rotating shaft 10 is an auxiliary component that allows the extension rod 6 to rotate at an angle of approximately 45° under the restriction of the rotating shaft 10. The rotating shaft 10 is fixedly connected to the oil reservoir 8. The side wall of the oil reservoir 8 has a groove adapted to the rotating shaft 10. The rotating shaft 10 is fixed to the side wall of the oil reservoir 8 via a through shaft. The two ends of the through shaft are fixedly welded to the groove on the side wall of the oil reservoir 8. The extension rod 6 is equipped with a first transmission rod 9. The first transmission rod 9 is strip-shaped and is fixedly connected to the side wall of the extension rod 6 by welding. When the extension rod 6 rotates, the extension rod 6 rotates synchronously.
[0028] The first transmission rod 9 is fixedly connected to the oil storage tank 8 via the second transmission rod 11. The second transmission rod 11 is made of telescopic stacked plates, and its length changes according to the movement of the first transmission rod 9. The second transmission rod 11 is fixedly connected to the first transmission rod 9, and its other end is fixedly connected to the oil storage tank 8. Both ends of the second transmission rod 11 are fixedly connected to the first transmission rod 9 and the oil storage tank 8 by welding.
[0029] The oil reservoir 8 is equipped with an oil pump pipe 14 for discharging lubricating oil. The oil pump pipe 14 is existing technology; it generates pressure through external pressure, drawing lubricating oil from the oil reservoir 8 into the pipe. The oil pump pipe 14 is fixed inside the oil reservoir 8 by a pressure pump, which is also existing technology. A stop button 12 is located on the side wall of the oil reservoir 8; the stop button 12 is the start button for the pressure pump and is fixedly connected to it. A strike rod 13 is located inside the second transmission rod 11. The strike rod 13 is made of a telescopic folding plate component, allowing the second transmission rod 11 to fold simultaneously. After the second transmission rod 11 is folded halfway, the strike rod 13 stops folding and strikes the stop button 12. The oil reservoir 8 is equipped with a lubricating oil filling pipe 15 for inputting lubricating oil. The filling pipe 15 is a prior art technology. Its bottom is fixedly connected to the oil reservoir 8, and its other end extends to the back of the lock body 2, which is convenient for the staff to add lubricating oil later. The extension rod 6 is equipped with multiple oil spray pipes 16 for spraying lubricating oil. There are a total of three oil spray pipes 16. The oil spray pipes 16 can also spray lubricating oil when the extension rod 6 is rotated, thereby enriching the lubricating oil spray path and increasing the coverage of the lubricating oil on the front end of the key. The oil spray pipes 16 are fixedly connected to the oil pump pipe 14. The oil spray pipes 16 are connected to the oil pump pipe 14 through an auxiliary connecting pipe and are fixedly connected.
[0030] The working principle of this utility model is as follows:
[0031] The user inserts the key into the keyhole 3. Due to the presence of the limiting post 4, the insertion depth of the key is restricted, preventing damage to the keyhole 3 due to excessive insertion. Simultaneously, the anti-extension body 5 also provides protection, ensuring the key is not over-inserted. When lubrication of the keyhole 3 is required, the pressure pump can be activated by operating the stop button 12 on the oil reservoir 8. The pressure pump generates pressure through the pump oil pipe 14, drawing lubricating oil from the oil reservoir 8 and delivering it to the oil injection pipe 16.
[0032] The oil spray pipe 16 sprays lubricating oil as the extension rod 6 rotates, enriching the oil spray path and increasing the coverage area of the key tip. This helps reduce friction between the key and the keyhole 3, extending the lock's lifespan. The striking pin 7 contacts the key tip and transfers excess force to the extension rod 6. The spring inside the striking pin 7 increases its reaction force, preventing deformation after impact. This design ensures smooth key insertion and removal while protecting the keyhole 3 from damage. If more lubricating oil is needed, it can be added via the oil filler pipe 15. The bottom of the oil filler pipe 15 is fixedly connected to the oil reservoir 8, while the other end extends to the back of the lock body 2 for easy operation.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
