Description

Technical Field

[0001] This utility model relates to the field of access control, and in particular to a slow-opening and slow-closing access control system. Background Technology

[0002] Access control systems are a modern security management system and an effective measure to ensure security at the entrances and exits of important departments. Therefore, they are widely used in various places, such as personnel attendance, workplace security, and access control for residents in residential communities.

[0003] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: after the access control system identifies the user, the door can be opened. However, if the user uses a lot of force to open the door, the door will open quickly and may injure other people. When closing the door, if the user does not hold the door, the door will collide with the door frame, which will not only produce a loud impact sound, but also cause damage to the door if the door panel and the door frame collide for a long time. Therefore, a slow-opening and slow-closing access control system is proposed. Utility Model Content

[0004] To address the issues of excessive force required to open doors, which can lead to rapid opening and potential injury to others, and the impact of the door hitting the frame without user assistance, causing loud noise and potential damage due to prolonged impact, this invention provides a slow-opening and slow-closing access control system.

[0005] This utility model provides a soft-opening and soft-closing access control system, which adopts the following technical solution:

[0006] A soft-opening and soft-closing access control system includes a door frame and a door panel rotatably mounted on the door frame. A buffer housing is fixedly installed on one side of the door frame, and an L-plate is fixedly installed on one side of the door panel. A door suction ball adapted to the buffer housing is fixedly installed at one end of the L-plate.

[0007] A fixing block is fixedly installed on the inner wall of the buffer housing. A secondary spring is fixedly installed on one side of the fixing block. A moving block is fixedly installed on one end of the secondary spring. A first sliding component is provided on one side of the moving block. A support rod is hinged to the other side of the moving block. A buffer plate is hinged to the end of the support rod away from the moving block. A circular groove adapted to the door suction ball is opened on the outer side of the buffer plate. An installation groove is opened on one side of the buffer housing. A bottom plate is provided on the inner wall of the installation groove inside the buffer housing. A main buffer is in contact with the inner side of the bottom plate. The side of the main buffer away from the bottom plate is in contact with the buffer plate.

[0008] By adopting the above technical solution, when the door is closed, the door panel can drive the L-plate and the door suction ball to move. The door suction ball can first touch the buffer plate inside the buffer housing installed on the door frame. The buffer plate can squeeze the secondary spring and the main buffer to buffer the force received, thereby reducing the impact noise when the door panel and the door frame collide and the damage caused by prolonged impact between the door panel and the door frame. When the force used by the staff to open the door panel is too great, the door suction ball can drive the buffer plate to move outward under the action of the magnet. The buffer plate stretches the secondary spring and the main buffer. The main buffer and the secondary spring can buffer the force received by the buffer plate, thereby slowing down the opening speed and reducing the possibility of injury to others due to the fast opening speed.

[0009] Optionally, a telescopic spring is fixedly installed inside the base plate, and a locking block is fixedly installed at one end of the telescopic spring. A locking groove adapted to the locking block is opened inside the buffer housing.

[0010] By adopting the above technical solution, if the main buffer malfunctions during use, the staff can control the movement of the locking block, causing the locking block to push the telescopic spring to retract and separate from the locking groove on the buffer housing. Then the base plate can be quickly removed, and the main buffer inside the buffer housing can be taken out for replacement.

[0011] Optionally, limit blocks are fixedly installed on both sides of the main buffer, and limit grooves adapted to the limit blocks are opened inside the buffer plate and the base plate.

[0012] By adopting the above technical solutions, the limiting block and limiting groove can increase the contact area between the main buffer and the buffer plate and the base plate, making the connection between the main buffer and the buffer plate and the base plate more stable.

[0013] Optionally, a push rod is fixedly installed on the outer side of the card block, and an elongated sliding hole is opened on the outer side of the base plate, with the push rod disposed inside the elongated sliding hole.

[0014] By adopting the above technical solution, the push rod can be easily pushed by the staff to move the block.

[0015] Optionally, a magnet is fixedly installed on the inner wall of the circular groove inside the buffer plate, and the magnet can attract and fix the door suction ball.

[0016] By adopting the above technical solution, the magnet can attract the door suction ball during use, reducing the repeated rebound of the door suction ball during use.

[0017] Optionally, a first slider is fixedly installed on the inner side of the card block, and a first groove adapted to the first slider is opened inside the base plate.

[0018] By adopting the above technical solution, the first slider and the first groove can limit the movement range of the block, and at the same time make the block move more smoothly.

[0019] Optionally, the first sliding component includes a second slider, one side of which is fixedly connected to the moving block, and the interior of the buffer housing is provided with a second groove that is adapted to the second slider.

[0020] By adopting the above technical solution, the second slider and the second slide can limit the movement range of the moving block, and at the same time make the moving block move more smoothly.

[0021] Optionally, the end of the latch block away from the telescopic spring has a guide angle that is inclined toward the buffer housing.

[0022] By adopting the above technical solution, when installing the base plate, the buffer housing can push the locking block to move through the guide angle, so that the buffer housing can be quickly connected to the base plate.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. When the door is closed, the door panel can move the L-plate and the door suction ball. The door suction ball can first touch the buffer plate inside the buffer housing installed on the door frame. The buffer plate can squeeze the secondary spring and the main buffer to buffer the force received, thereby reducing the impact noise when the door panel and the door frame touch and the damage caused by long-term impact between the door panel and the door frame. When the force of the staff to open the door panel is too great, under the action of the magnet, the door suction ball can drive the buffer plate to move outward. The buffer plate stretches the secondary spring and the main buffer. The main buffer and the secondary spring can buffer the force received by the buffer plate, thereby slowing down the opening speed and reducing the possibility of injuring others due to the fast opening speed.

[0025] 2. In the use of this utility model, once the main buffer malfunctions, the operator can remove the buffer housing and push the push rod to move it. The push rod can drive the locking block to move, causing the locking block to push the telescopic spring to retract and separate from the locking groove on the buffer housing. Then the base plate can be quickly removed, and the main buffer inside the buffer housing can be taken out for replacement. The operation is simple and convenient. Attached Figure Description

A moving block 8 is fixedly installed on one end of the secondary spring 7. A support rod 10 is hinged to the other side of the moving block 8. A buffer plate 11 is hinged to the end of the support rod 10 away from the moving block 8. A circular groove adapted to the door suction ball 5 is opened on the outer side of the buffer plate 11. A magnet 18 is fixedly installed on the inner wall of the circular groove opened inside the buffer plate 11. The magnet 18 can attract and fix the door suction ball 5. When in use, the magnet 18 can attract the door suction ball 5, reducing the repeated rebound of the door suction ball 5 during use.

[0034] Please refer to Figure 2 A first sliding component 9 is provided on one side of the moving block 8. The first sliding component 9 includes a second slider 91. One side of the second slider 91 is fixedly connected to the moving block 8. A second sliding groove 92 adapted to the second slider 91 is provided inside the buffer housing 3. The second slider 91 and the second sliding groove can limit the movement range of the moving block 8 and make the moving block 8 move more smoothly.

[0035] Please refer to Figure 2A mounting groove is provided on one side of the buffer housing 3. A base plate 12 is provided on the inner wall of the mounting groove inside the buffer housing 3. The inner side of the base plate 12 contacts the main buffer 13. The side of the main buffer 13 away from the base plate 12 contacts the buffer plate 11. Limiting blocks 16 are fixedly installed on opposite sides of the main buffer 13. Limiting grooves adapted to the limiting blocks 16 are provided inside the buffer plate 11 and the base plate 12. The limiting blocks 16 and the limiting grooves can increase the contact area between the main buffer 13 and the buffer plate 11 and the base plate 12, making the connection between the main buffer 13 and the buffer plate 11 and the base plate 12 more stable. When in use, the buffer plate 11 is touched by the door suction ball 5, and the moving block 8 can be moved by the support rod 10. The moving block 8 can squeeze the secondary spring 7 with the cooperation of the second slider 91 and the second slide groove 92. When the buffer plate 11 moves, it can squeeze the main buffer 13 on the inner side of the buffer plate 11. The main buffer 13 and the secondary spring 7 can buffer the force on the buffer plate 11, thereby reducing the impact sound when the door panel 2 and the door frame 1 touch and the damage that may occur when the door panel 2 and the door frame 1 are impacted for a long time.

[0036] Please refer to Figure 2 and Figure 3 A telescopic spring 14 is fixedly installed inside the base plate 12, and a locking block 15 is fixedly installed at one end of the telescopic spring 14. A slot adapted to the locking block 15 is provided inside the buffer housing 3. During use, if the main buffer 13 malfunctions, the operator can control the locking block 15 to move, causing it to push the telescopic spring 14 to retract and separate from the slot on the buffer housing 3. Then, the base plate 12 can be quickly removed, and the main buffer 13 inside the buffer housing 3 can be replaced. A push rod 17 is fixedly installed on the outer side of the locking block 15. An elongated sliding hole is provided on the outer side of the base plate 12, and the push rod 17 is located inside the elongated sliding hole, allowing the operator to easily move the locking block 15.

[0037] Please refer to Figure 2 and Figure 3 A first slider 19 is fixedly installed on the inner side of the locking block 15. A first groove adapted to the first slider 19 is opened inside the base plate 12. The first slider 19 and the first groove can limit the movement range of the locking block 15 and make the locking block 15 move more smoothly. The end of the locking block 15 away from the telescopic spring 14 has a guide angle 20 inclined towards the buffer housing 3. When installing the base plate 12, the buffer housing 3 can push the locking block 15 to move through the guide angle 20, so that the buffer housing 3 can be quickly connected to the base plate 12, making the installation of the base plate 12 faster and more efficient.

[0038] The implementation principle of this utility model is as follows: When the door is closed, the door panel 2 can drive the L-plate 4 and the door suction ball 5 to move. The door suction ball 5 can first touch the buffer plate 11 inside the buffer housing 3 installed on the door frame 1. The magnet 18 on the buffer plate 11 can attract the door suction ball 5. At the same time, the buffer plate 11 being touched by the door suction ball 5 can push the moving block 8 to move through the support rod 10. The moving block 8 can squeeze the secondary spring 7 in cooperation with the second slider 91 and the second slide groove 92. When the buffer plate 11 moves, it can squeeze the main buffer 13 on the inner side of the buffer plate 11. The main buffer 13 and the secondary spring 7 can buffer the force on the buffer plate 11, thereby reducing the door's closing force. The impact sound when the door panel 2 and the door frame 1 touch, and the damage that may occur when the door panel 2 and the door frame 1 are impacted for a long time. When the force used by the staff to open the door panel 2 is too great, the door suction ball 5 can drive the buffer plate 11 to move outward under the action of the magnet 18. The buffer plate 11 can drive the moving block 8 to move through the support rod 10. The moving block 8 can stretch the auxiliary spring 7 with the cooperation of the second slider 91 and the second slide groove 92. When the buffer plate 11 moves outward, it can stretch the main buffer 13 on the inner side of the buffer plate 11. The main buffer 13 and the auxiliary spring 7 can buffer the force on the buffer plate 11, thereby slowing down the opening speed and reducing the possibility of injuring others due to the fast opening speed.

[0039] If the main buffer 13 malfunctions during use, the staff can remove the buffer housing 3 and push the push rod 17 to move it. The push rod 17 can drive the locking block 15 to move, causing the locking block 15 to push the telescopic spring 14 to retract and separate from the locking groove on the buffer housing 3. Then the base plate 12 can be quickly removed, and the main buffer 13 inside the buffer housing 3 can be taken out for replacement. The operation is simple and convenient.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
