Description

Technical Field

[0001] This utility model belongs to the field of lock cylinder structure technology, and in particular relates to a safety lock cylinder structure. Background Technology

[0002] To protect their privacy and personal safety and property, people install a security lock on their doors and use a key to lock or unlock them, thereby preventing criminals from entering to steal property or causing personal safety issues.

[0003] For example, Chinese patent CN216517380U discloses a lock cylinder structure, characterized by including a lock shell, a front lock cylinder, a rear lock cylinder, and a dial. The front and rear lock cylinders are rotatably connected within the lock shell and are coaxially arranged. The lock shell has a notch, and the dial is located within the notch and is rotatably connected to the front and rear lock cylinders. The lock shell is integrally formed from a steel or iron blank. The front and rear lock cylinders are made of copper, and the dial is made of iron. The outer wall of the lock shell is covered with a first electroplating layer, and the outer ends of the front and rear lock cylinders are covered with a second electroplating layer. The advantages are that the lock shell is integrally formed from a steel blank, which has good rigidity, and the overall outer wall of the lock cylinder is covered with an electroplating layer, which has a good anti-oxidation and anti-rust effect.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has some drawbacks in use, such as: dust may enter the lock cylinder during operation, and excessive dust accumulation may cause blockage, potentially leading to unlocking failure. Additionally, the device makes key insertion difficult, requiring lubricant to be applied to the key for easier insertion. Therefore, we propose a new secure lock cylinder structure. Utility Model Content

[0006] The purpose of this invention is to provide a security lock cylinder structure to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a security lock cylinder structure, comprising:

[0008] An entrance door has a limiting groove inside, a lock cylinder body is fixedly installed in the limiting groove, a rectangular plate is slidably installed in the limiting groove and on one side of the lock cylinder body, and several springs fixed to the inner wall of the limiting groove are fixedly installed at the bottom of the rectangular plate.

[0009] A drive assembly, located inside the entrance door, is used to drive the rectangular plate to slide.

[0010] A rotating groove is provided inside the entrance door and is connected to a limiting groove. A rotating disk is rotatably installed inside the rotating groove. A sliding groove is provided inside the rotating disk. Two sliding plates are slidably installed inside the sliding groove. Several springs are fixed to the inner wall of the sliding groove on the side of the two sliding plates that are far apart from each other. Solid lubricant is provided on the side of the two sliding plates that are close to each other, and the solid lubricant slides in cooperation with the sliding groove. A disc is inserted into the rotating disk.

[0011] A limiting component is located inside the disk and is used to limit the position of the disk.

[0012] In this technical solution, when unlocking is required, the set drive component can drive the rectangular plate to slide downwards. At the same time, several springs are compressed and contracted. When the rectangular plate slides to the appropriate position, the person can insert the key into the keyhole of the disc, the rotating disc and the lock cylinder body in sequence to unlock. After unlocking, under the action of the rebound force of several springs, the rectangular plate will slide upwards and block the keyhole of the lock cylinder body to prevent external dust from entering the keyhole of the lock cylinder body.

[0013] Simultaneously, when the key is inserted, it first enters the disc, then the rotating disc, and both sides of the key come into contact with two solid lubricants. The two solid lubricants lubricate the key, preventing it from getting stuck during insertion. At the same time, under the rebound force of several springs, the two sliding plates slide and move closer to each other. The two sliding plates push the two solid lubricants to slide and move closer to each other, ensuring that the two solid lubricants can always lubricate the key.

[0014] When the solid lubricant needs to be replaced, the operator can pull the disc outward using the set limiting component. Then, two solid lubricants can be replaced. After the solid lubricant is replaced, the operator inserts the disc into the rotating disc. The set limiting component can fix the position of the disc. At the same time, the rotation of the disc can drive the rotating disc to rotate, which facilitates the replacement of solid lubricant without the use of tools and is simple to operate.

[0015] In the above technical solution, the driving component further includes:

[0016] A rack is fixedly installed on one side of a rectangular plate, and a gear is meshed on one side of the rack. A gear is fixedly installed on one end of the gear, and a rack is meshed on the bottom of the gear. One end of the rack passes through a limiting groove and extends to the outside. Both the rack and the rack are slidably connected to the limiting groove, and both the gear and the gear are rotatably connected to the limiting groove.

[0017] In this technical solution, when unlocking is required, the user first pulls rack two, which drives gear two, which in turn drives gear one, to rotate. Gear one then drives rack one, which in turn drives rack one, which in turn drives rack one, to slide downwards. Rack one then drives rectangular plate to slide downwards, while several springs one are compressed and contracted. When the rectangular plate slides to the appropriate position, the user can insert the key into the keyhole of the disc, rotating disc, and lock cylinder body in sequence to unlock. After unlocking, under the rebound force of several springs one, the rectangular plate will slide upwards and block the keyhole of the lock cylinder body, preventing external dust from entering the keyhole of the lock cylinder body.

[0018] In the above technical solution, the limiting component further includes:

[0019] Two sliding grooves are provided, both of which are located within the disc. Limiting blocks are slidably installed within each sliding groove. Several springs are fixedly installed at the ends of the two limiting blocks that are close to each other and are fixed to the inner walls of the corresponding sliding grooves. The ends of the two limiting blocks that are far apart from each other pass through the two sliding grooves and extend into the rotating disc. The ends of the two limiting blocks that are far apart from each other are inserted into the rotating disc. One side of each of the two limiting blocks passes through the two sliding grooves and extends to the outside.

[0020] In this technical solution, when the solid lubricant needs to be replaced, firstly, pull the two limiting blocks to slide closer to each other. At the same time, several springs are compressed and contracted. After one end of both limiting blocks is disengaged from the rotating disk, the operator can pull the two limiting blocks outward and remove the disc. Then, the two solid lubricants can be replaced. After the solid lubricant is replaced, the operator inserts the disc into the rotating disk and then releases the two limiting blocks. Under the rebound force of several springs, the two limiting blocks slide away from each other. After both limiting blocks are inserted into the rotating disk, the position of the disc can be fixed. At the same time, the rotation of the disc can drive the rotating disk to rotate, which facilitates the replacement of solid lubricant without the need for tools and is simple to operate.

[0021] In the above technical solution, a pull rod is further fixedly installed at one end of the rack two.

[0022] In this technical solution, the rack and pinion are easily pulled by the provided pull rod.

[0023] In the above technical solution, the circumferential sidewall of the disk is in close contact with the rotating disk.

[0024] In this technical solution, the stability of the disk's rotation within the rotating disk is ensured.

[0025] In the above technical solution, furthermore, the axes of gear one and gear two are located on the same horizontal line.

[0026] In this technical solution, it is ensured that the rotation of gear one can drive gear two to rotate stably.

[0027] In the above technical solution, furthermore, the two sides of the solid lubricant are in close contact with the inner wall of the sliding groove and the disk, respectively.

[0028] In this technical solution, it is ensured that the position of the solid lubricant will not shift during use.

[0029] The beneficial effects of this utility model are:

[0030] 1. In this safety lock cylinder structure, when unlocking is required, the drive component can drive the rectangular plate to slide downwards. At the same time, several springs are compressed and contracted. When the rectangular plate slides to the appropriate position, the person can insert the key into the keyhole of the disc, the rotating disc, and the lock cylinder body in sequence to unlock. After unlocking, under the rebound force of several springs, the rectangular plate will slide upwards and block the keyhole of the lock cylinder body to prevent external dust from entering the keyhole of the lock cylinder body.

[0031] 2. In this safety lock cylinder structure, when the key is inserted, it first enters the disc, then the rotating disc, and both sides of the key come into contact with two solid lubricants. The two solid lubricants lubricate the key, preventing it from getting stuck during insertion. At the same time, under the rebound force of several springs, two sliding plates slide and move closer to each other. The two sliding plates push the two solid lubricants to slide and move closer to each other, ensuring that the two solid lubricants can always lubricate the key, preventing it from getting stuck when unlocking.

[0032] 3. In this safety lock cylinder structure, when the solid lubricant needs to be replaced, the operator can pull the disc outward to remove it through the set limiting component. Then, two solid lubricants can be replaced. After the solid lubricant is replaced, the operator inserts the disc into the rotating disc. The set limiting component can fix the position of the disc. At the same time, the rotation of the disc can drive the rotating disc to rotate, which facilitates the replacement of solid lubricant without the need for tools and is simple to operate.

[0047] Example 1:

[0048] Please see Figure 1 - Figure 7 As shown, this embodiment provides a security lock cylinder structure, including:

[0049] An entrance door 1 has a limiting groove 2 inside it. A lock cylinder body 3 is fixedly installed inside the limiting groove 2. A rectangular plate 4 is slidably installed inside the limiting groove 2 and on one side of the lock cylinder body 3. Several springs 5 ​​fixed to the inner wall of the limiting groove 2 are fixedly installed at the bottom of the rectangular plate 4.

[0050] A drive assembly is located inside the entrance door 1 and is used to drive the rectangular plate 4 to slide.

[0051] Rotating groove 11 is opened inside the entrance door 1 and is connected to limiting groove 2. Rotating disk 6 is rotatably installed in rotating groove 11. Sliding groove 7 is opened in rotating disk 6. Two sliding plates 8 are slidably installed in sliding groove 7. Several springs 9 fixed to the inner wall of sliding groove 7 are fixedly installed on the side of the two sliding plates 8 that are far apart from each other. Solid lubricant 10 is provided on the side of the two sliding plates 8 that are close to each other, and the solid lubricant 10 slides with sliding groove 7. A disc 12 is inserted into rotating disk 6.

[0052] A limiting component is located inside the disk 12 and is used to limit the position of the disk 12.

[0053] When unlocking is required, the drive component can drive the rectangular plate 4 to slide downwards, while several springs 5 ​​are compressed and contracted. When the rectangular plate 4 slides to the appropriate position, the person can insert the key into the keyhole of the disc 12, the rotating disc 6 and the lock cylinder body 3 in sequence to unlock. After unlocking, under the rebound force of several springs 5, the rectangular plate 4 will slide upwards and block the keyhole of the lock cylinder body 3 to prevent external dust from entering the keyhole of the lock cylinder body 3.

[0054] Simultaneously, when the key is inserted, it first enters the disc 12, and then enters the rotating disc 6. Both sides of the key come into contact with two solid lubricants 10, which lubricate the key and prevent it from getting stuck during insertion. At the same time, under the rebound force of several springs 9, the two sliding plates 8 slide and move closer to each other. The two sliding plates 8 push the two solid lubricants 10 to slide and move closer to each other, ensuring that the two solid lubricants 10 can always lubricate the key.

[0055] When the solid lubricant 10 needs to be replaced, the operator can pull the disc 12 outwards to remove it through the set limiting component. Then, two solid lubricants 10 can be replaced. After the solid lubricant 10 is replaced, the operator inserts the disc 12 into the rotating disk 6. The position of the disc 12 can be fixed by the set limiting component. At the same time, the rotation of the disc 12 can drive the rotating disk 6 to rotate, which makes it convenient to replace the solid lubricant 10 without the need for tools and is simple to operate.

[0056] In this embodiment, the driving component includes:

[0057] Rack 13 is fixedly installed on one side of rectangular plate 4, and gear 14 is meshed on one side of rack 13. Gear 2 15 is fixedly installed on one end of gear 14, and rack 2 16 is meshed on the bottom of gear 2 15. One end of rack 2 16 passes through the limiting groove 2 and extends to the outside. Rack 13 and rack 2 16 are slidably connected to the limiting groove 2, and gear 14 and gear 2 15 are rotatably connected to the limiting groove 2.

[0058] When unlocking is required, the user first pulls rack 2 16, which drives gear 2 15 to rotate. Gear 2 15 drives gear 1 14 to rotate, and gear 1 14 drives rack 1 13 to slide downward. Rack 1 13 drives rectangular plate 4 to slide downward. At the same time, several springs 1 5 are compressed and contracted. When rectangular plate 4 slides to the appropriate position, the user can insert the key into the keyhole of disc 12, rotating disc 6 and lock cylinder body 3 in sequence to unlock. After unlocking, under the rebound force of several springs 1 5, rectangular plate 4 will slide upward and block the keyhole of lock cylinder body 3 to prevent external dust from entering the keyhole of lock cylinder body 3.

[0059] In this embodiment, the limiting component includes:

[0060] Two sliding grooves 20 are formed inside the disc 12. Limiting blocks 18 are slidably installed inside the sliding grooves 20. Several springs 3 19 are fixedly installed at the ends of the two limiting blocks 18 that are close to each other and are fixed to the inner wall of the corresponding sliding grooves 20. The ends of the two limiting blocks 18 that are far apart from each other pass through the two sliding grooves 20 and extend into the rotating disc 6. The ends of the two limiting blocks 18 that are far apart from each other are inserted into the rotating disc 6. One side of the two limiting blocks 18 passes through the two sliding grooves 20 and extends to the outside.

[0061] When the solid lubricant 10 needs to be replaced, firstly, pull the two limiting blocks 18 to slide and move closer to each other. At the same time, several springs 19 are compressed and contracted. After one end of the two limiting blocks 18 is disengaged from the rotating disk 6, the operator can pull the two limiting blocks 18 outward and remove the disc 12. Then, the two solid lubricants 10 can be replaced. After the solid lubricant 10 is replaced, the operator inserts the disc 12 into the rotating disk 6 and then releases the two limiting blocks 18. Under the rebound force of the several springs 19, the two limiting blocks 18 slide and move away from each other. After both limiting blocks 18 are inserted into the rotating disk 6, the position of the disc 12 can be fixed. At the same time, the rotation of the disc 12 can drive the rotating disk 6 to rotate, which is convenient for replacing the solid lubricant 10 without the need for tools and is simple to operate.

[0070] Example 4:

[0071] This embodiment provides a security lock cylinder structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] In this embodiment, the axes of gear 14 and gear 2 15 are located on the same horizontal line.

[0073] Among them, it is ensured that the rotation of gear 14 can drive gear 2 15 to rotate stably.

[0074] Example 5:

[0075] This embodiment provides a security lock cylinder structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0076] In this embodiment, the two sides of the solid lubricant 10 are in close contact with the inner wall of the sliding groove 7 and the disk 12, respectively.

[0077] Among these measures, it is ensured that the position of the solid lubricant 10 does not shift during use.

[0078] Working principle: When unlocking is required, the user first pulls the lever 17, which drives the rack 16 to pull outward. The rack 16 drives the gear 15 meshing with it to rotate. The gear 15 drives the gear 14 to rotate. The gear 14 drives the rack 13 meshing with it to slide downward. The rack 13 drives the rectangular plate 4 to slide downward. At the same time, several springs 5 ​​are compressed and contracted. When the rectangular plate 4 slides to the appropriate position, the user can insert the key into the keyhole of the disc 12, the rotating disc 6 and the lock cylinder body 3 in sequence to unlock. After unlocking, under the rebound force of several springs 5, the rectangular plate 4 will slide upward and block the keyhole of the lock cylinder body 3 to prevent external dust from entering the keyhole of the lock cylinder body 3.

[0079] Simultaneously, when the key is inserted, it first enters the disc 12, and then enters the rotating disc 6. Both sides of the key come into contact with two solid lubricants 10, which lubricate the key and prevent it from getting stuck during insertion. At the same time, under the rebound force of several springs 9, the two sliding plates 8 slide and move closer to each other. The two sliding plates 8 push the two solid lubricants 10 to slide and move closer to each other, ensuring that the two solid lubricants 10 can always lubricate the key.

[0080] When the solid lubricant 10 needs to be replaced, first pull the two limiting blocks 18 to slide and move closer to each other. At the same time, several springs 19 are compressed and contracted. When one end of the two limiting blocks 18 is disengaged from the rotating disk 6, the operator can pull the two limiting blocks 18 outward and remove the disc 12. Then, the two solid lubricants 10 can be replaced. After the solid lubricant 10 is replaced, the operator inserts the disc 12 into the rotating disk 6 and then releases the two limiting blocks 18. Under the rebound force of the several springs 19, the two limiting blocks 18 slide and move away from each other. When both limiting blocks 18 are inserted into the rotating disk 6, the position of the disc 12 can be fixed. At the same time, the rotation of the disc 12 can drive the rotating disk 6 to rotate, which is convenient for replacing the solid lubricant 10 without the need for tools and is simple to operate.
