Description
Technical Field
[0001] This utility model relates to the field of electronic lock cylinder technology, and in particular to an electronic lock cylinder structure with a reset baffle. Background Technology
[0002] The lock cylinder is the core component of a lock, responsible for controlling its opening. It employs multiple anti-theft technologies, including various irregularly shaped anti-picking pins and precision numbered pin structures, providing high security against technical unlocking. With the development of technology, electronic locks have gradually become more widely used. An electronic lock is an electronic product that uses password input to control the operation of circuits or chips (access control system), thereby controlling the closing of mechanical switches to complete the unlocking and locking tasks. Similarly, the electronic lock cylinder is the core component of an electronic lock.
[0003] The inventors believe that the following defects often exist: when the lock cylinder body is installed into the door lock frame, the door lock frame is too tall, and there is a lot of space above and below after the lock cylinder body is put in, which makes it difficult for the lock cylinder body to fit properly, resulting in the problem of the lock cylinder body shaking and becoming unstable after long-term use; therefore, an electronic lock cylinder structure with a reset baffle is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the lock cylinder body is difficult to adapt in the existing technology, resulting in the lock cylinder body shaking and becoming unstable after long-term use. Therefore, an electronic lock cylinder structure with a reset baffle is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electronic lock cylinder structure with a reset baffle, comprising a lock cylinder body, a blocking plate installed on one side of the lock cylinder body, slots provided on both sides of the lock cylinder body, thickening devices provided on the surfaces of the two lock cylinder body slots, the thickening devices comprising two fixing blocks, the two fixing blocks being fixedly connected to the surfaces of the two lock cylinder body slots respectively, thickening blocks being slidably connected to the inner side of the fixing blocks, a fixing rod being fixedly connected to one side of the fixing blocks, an operating plate being slidably connected to the arc surface of the fixing rod, a plug rod being fixedly connected to one side of the operating plate, and a slot being provided on one side of the thickening blocks.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up the thickening device, the upper and lower sides of the lock cylinder body are thickened to fit different door lock frame sizes. This avoids the situation where, when the lock cylinder body is installed into the door lock frame, the door lock frame is too tall, and there is a lot of space at the top and bottom after the lock cylinder body is placed in, making it difficult for the lock cylinder body to fit properly. This can lead to the lock cylinder body shaking and becoming unstable after long-term use, thus improving the practicality of the device.
[0007] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the fixing block, and the size of the insertion rod is adapted to the size of the slot.
[0008] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls it.
[0009] Preferably, a first spring is fitted onto the arc surface of the fixing rod, and the two ends of the first spring are fixedly connected to the operating plate and the fixing block, respectively.
[0010] The effect achieved by the above components is that the first spring improves the stability of the insert rod when it limits the thickening block.
[0011] Preferably, an anti-slip pad is fixedly connected to the upper surface of the thickened block, and the surface of the anti-slip pad is provided with a plurality of anti-slip protrusions.
[0012] The effect achieved by the above components is to further increase the stability of the lock cylinder body within the door lock frame and improve the service life of the device.
[0013] Preferably, the surface of the barrier plate is provided with a protective device, the protective device including a protective chamber, the protective chamber being slidably connected to the surface of the barrier plate, a rotating groove being provided on one side of the protective chamber, a rotating rod being fixedly connected to the surface of the rotating groove of the protective chamber, a protective plate being rotatably connected to the arc surface of the rotating rod, and two torsion springs being sleeved on the arc surface of the rotating rod, the two ends of the torsion springs being fixedly connected to the rotating groove of the protective plate and the protective chamber, respectively.
[0014] The effect achieved by the above-mentioned components is that by setting up protective devices, the lock cylinder body passing through the blocking plate is protected, avoiding damage to the lock cylinder body caused by collisions during transportation or dust accumulation during long-term idleness, which would prevent the lock cylinder body from being used normally.
[0015] Preferably, a support plate is fixedly connected to the surface of the protective compartment, a drive rod is threaded into the support plate, one end of the drive rod is rotatably connected to a connecting block, and a U-shaped frame is fixedly connected to the surface of the protective plate, with the U-shaped frame and the connecting block being slidably connected.
[0016] The aforementioned components achieve the following effect: they limit the movement of the protective plate, preventing the protective plate from remaining closed due to the torsion spring when the worker places the protective compartment on the barrier, thus avoiding the situation where the worker has to use their fingers to continuously block the protective plate, which would affect the worker's work efficiency.
[0017] Preferably, a positioning rod is fixedly connected to the side of the connecting block near the drive rod, and the arc surface of the positioning rod is slidably connected to the support plate.
[0018] The effect achieved by the above components is that the positioning rod restricts the connecting block from rotating with the drive rod, so that the workers can quickly and accurately insert the connecting block into the U-shaped frame.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting a thickening device, the upper and lower sides of the lock cylinder body are thickened to fit different door lock frame sizes. This avoids the situation where, when the lock cylinder body is installed into the door lock frame, the door lock frame is too tall, and there is a lot of space at the top and bottom after the lock cylinder body is placed in, making it difficult for the lock cylinder body to fit properly. This can lead to the lock cylinder body shaking and becoming unstable after long-term use, thus improving the practicality of the device.
[0021] 2. In this utility model, by setting a protective device, the lock cylinder body passing through the blocking plate is protected, avoiding damage to the lock cylinder body caused by collisions during transportation or dust accumulation during long-term idleness, thus preventing the lock cylinder body from being used normally.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: an electronic lock cylinder structure with a reset baffle, including a lock cylinder body 1, a baffle plate 2 installed on one side of the lock cylinder body 1, and slots on both sides of the lock cylinder body 1. Thickening devices 3 are provided on the surfaces of the slots of the two lock cylinder bodies 1. By setting the thickening devices 3, the upper and lower sides of the lock cylinder body 1 are thickened to accommodate different door lock frame sizes. This avoids the situation where, when the lock cylinder body 1 is installed into the door lock frame, the door lock frame is too large, resulting in a large amount of space at the top and bottom, making it difficult for the lock cylinder body 1 to fit properly. This can lead to instability and shaking of the lock cylinder body 1 after prolonged use, thus improving the practicality of the device. A protective device 4 is provided on the surface of the baffle plate 2. By setting the protective device 4, the lock cylinder body 1 passing through the baffle plate 2 is protected, preventing damage to the lock cylinder body 1 caused by collisions during transportation or dust accumulation during long-term idleness, thus preventing the lock cylinder body 1 from becoming unusable.
[0029] The specific setup and function of the thickening device 3 and the protective device 4 will be explained in detail below.
[0030] Reference Figure 2 and Figure 3 As shown in this embodiment: the thickening device 3 includes two fixing blocks 31, which are respectively fixedly connected to the surfaces of the slots of the two lock cylinder bodies 1. A thickening block 32 is slidably connected to the inner side of the fixing block 31. A fixing rod 33 is fixedly connected to one side of the fixing block 31. An operating plate 34 is slidably connected to the arc surface of the fixing rod 33. A insertion rod 35 is fixedly connected to one side of the operating plate 34. A slot 36 is provided on one side of the thickening block 32. A limiting plate 37 is fixedly connected to the end of the fixing rod 33 away from the fixing block 31. The size of the insertion rod 35 matches the size of the slot 36. When the operator pulls the operating plate 34, the operating plate 34 slides on the arc surface of the fixing rod 33. At this time, the limiting plate 37 achieves the effect of limiting the maximum sliding distance of the operating plate 34 on the arc surface of the fixing rod 33, thus preventing the operator from... When the operating plate 34 is pulled, if the pulling force is too great, the operating plate 34 may detach from the arc surface of the fixing rod 33. The arc surface of the fixing rod 33 is fitted with a first spring 38. The two ends of the first spring 38 are fixedly connected to the operating plate 34 and the fixing block 31, respectively. When the operator releases the operating plate 34, the rebound force of the first spring 38 causes the operating plate 34 to slide on the arc surface of the fixing rod 33. At the same time, the operating plate 34 drives the insertion rod 35 to move until the insertion rod 35 is inserted into the slot 36. At this time, the first spring 38 improves the stability of the insertion rod 35 when it limits the thickening block 32. The upper surface of the thickening block 32 is fixedly connected with an anti-slip pad 39. The surface of the anti-slip pad 39 is provided with several anti-slip protrusions, which further increases the stability of the lock cylinder body 1 in the door lock frame and improves the service life of the device.
[0031] Reference Figure 4 and Figure 5 As shown, specifically, the protective device 4 includes a protective chamber 41, which is slidably connected to the surface of the blocking plate 2. A rotating groove is provided on one side of the protective chamber 41. A rotating rod 42 is fixedly connected to the surface of the rotating groove of the protective chamber 41. A protective plate 43 is rotatably connected to the arc surface of the rotating rod 42. Two torsion springs 49 are sleeved on the arc surface of the rotating rod 42. The two ends of the torsion springs 49 are fixedly connected to the rotating groove of the protective plate 43 and the protective chamber 41, respectively. A support plate 44 is fixedly connected to the surface of the protective chamber 41. A drive rod 45 is threaded into the support plate 44. A connecting block 46 is rotatably connected to one end of the drive rod 45. A U-shaped frame 47 is fixedly connected to the surface of the protective plate 43, and the U-shaped frame 47 is slidably connected to the surface of the connecting block 46. When the operator needs to use the protective chamber 41 to protect the lock cylinder body 1, they pull the protective plate 43, causing it to rotate on the arc surface of the rotating rod 42 until it rotates ninety degrees, making the protective plate 43 parallel to the blocking plate 2. At this time, the drive rod 45 is rotated to... The drive rod 45 moves threadedly within the support plate 44, simultaneously driving the connecting block 46 to move until it inserts into the U-shaped frame 47. This achieves the effect of limiting the position of the protective plate 43, preventing the protective plate 43 from remaining closed due to the torsion spring 49 when the worker places the protective chamber 41 on the blocking plate 2. This would force the worker to use their fingers to continuously block the protective plate 43, thus affecting the worker's work efficiency. A positioning rod 48 is fixedly connected to the side of the connecting block 46 near the drive rod 45. The arc surface of the positioning rod 48 is slidably connected to the support plate 44. When the worker rotates the drive rod 45, it moves threadedly within the support plate 44, simultaneously driving the connecting block 46 to move. The connecting block 46 then drives the positioning rod 48 to slide within the support plate 44. At this point, the positioning rod 48 achieves the effect of limiting the connecting block 46 from rotating with the drive rod 45, allowing the worker to quickly and accurately insert the connecting block 46 into the U-shaped frame 47.
[0032] Working principle: When the operator needs to increase the thickness of the lock cylinder body 1 to fit different door lock frames, they pull the operating plate 34, causing it to slide on the arc surface of the fixed rod 33. The first spring 38 is stretched, and the operating plate 34 simultaneously drives the insertion rod 35 to move until the insertion rod 35 no longer obstructs the thickening block 32 from rising. At this point, the thickening block 32 is pulled out from the fixed block 31. After being pulled out, the operating plate 34 is released, and the rebound force of the first spring 38 causes the operating plate 34 to slide on the arc surface of the fixed rod 33. At the same time, the operating plate 34 drives the insertion rod 35 to move. The device moves until the insertion rod 35 is inserted into the slot 36. At this point, the thickened lock cylinder body 1 is placed into the door lock frame, and the anti-slip pad 39 fits snugly against the top and bottom of the door lock frame. This achieves the effect of thickening the top and bottom sides of the lock cylinder body 1 to accommodate different door lock frame sizes. This avoids the situation where, when the lock frame is too tall, there is too much space at the top and bottom after the lock cylinder body 1 is placed in, making it difficult for the lock cylinder body 1 to fit properly. This would result in the lock cylinder body 1 shaking and becoming unstable after long-term use, thus improving the practicality of the device.
[0033] When the operator needs to use the protective chamber 41 to protect the lock cylinder body 1, they pull the protective plate 43. The protective plate 43 rotates on the arc surface of the rotating rod 42 until it rotates 90 degrees, making the protective plate 43 parallel to the blocking plate 2. At this time, they rotate the drive rod 45, causing it to move threadedly within the support plate 44. Simultaneously, the drive rod 45 drives the connecting block 46 to move, and the connecting block 46 drives the positioning rod 48 to slide within the support plate 44 until the connecting block 46 inserts into the U-shaped bracket 47. Then, the protective chamber 41 is placed on the blocking plate 2 and pulled downwards until the protective chamber 41 completely covers the surface of the blocking plate 2. Then, rotate the drive rod 45 again, causing it to move threadedly within the support plate 44. Simultaneously, the drive rod 45 drives the connecting block 46 to move, and the connecting block 46 drives the positioning rod 48 to slide within the support plate 44 until the connecting block 46 disengages from the U-shaped frame 47. At this time, the torsion protection plate 43 of the torsion spring 49 rotates on the arc surface of the rotating rod 42 until the protection plate 43 is completely closed. This achieves the effect of protecting the lock cylinder body 1 that passes through the blocking plate 2, preventing damage to the lock cylinder body 1 caused by collisions during transportation or dust accumulation during long-term idleness, thus preventing the lock cylinder body 1 from being used normally.
