Description

Technical Field

[0001] The utility model relates to the technical field of access control locks, and in particular to a bracket for installing an intelligent access control lock. Background Art

[0002] Magnetic locks used in access control systems are similar in design to electromagnets, operating on the principle of electromagnetism. When current flows through silicon steel sheets, the electromagnetic lock generates a strong suction force, firmly gripping the metal block attached to the door frame and locking the door. Once the access control system, which controls the electromagnetic lock's power supply, recognizes the correct person, it shuts off the power, allowing the electromagnetic lock to open, eliminating its suction.

[0003] When installing a magnetic lock, the lock body and the iron block used to adsorb the lock body need to be installed on the door body and door frame respectively. The iron block is generally fixed to the door frame using a special mounting bracket. When closing the door, the magnetic lock and the iron block will produce collision noise when they come into contact. However, the mounting bracket in the prior art lacks a mechanism that can eliminate the impact generated when closing the door. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The bracket installed on the smart access control lock realizes door rebound buffering by setting structures such as a buffer cylinder, a lock body, and a lock block. After the user enters the access control, the door will rotate toward the connection due to automatic rebound. When the door rotates to a certain position, the buffer head contacts the surface of the lock body, so that the buffer head is squeezed by the inertia from the door and the lock body, causing the buffer head to move quickly toward the inside of the buffer cylinder.

[0021] See also Figure 1-Figure 2 A lock core 21 is provided inside the lock block 2, and a functional block 22 is provided on one side of the lock core 21. A control groove is provided inside the lock block 2 at a position corresponding to the position of the functional block 22, and a control module is installed inside the control groove. An electromagnetic strip 23 is fixedly installed on one side of the lock core 21. There are three electromagnetic strips 23, and the width of the middle electromagnetic strip 23 is the sum of the widths of the upper and lower electromagnetic strips 23.

[0022] An iron block 31 is fixedly connected to one side of the top of the adapter block 3 close to the locking block 2. The iron block 31 and the electromagnetic bar 23 after power is energized are attracted to each other by opposite charges. A sliding sleeve 32 is fixedly installed on one side of the adapter block 31. A through groove is provided inside the adapter block 3 at the sliding sleeve 32. The sliding sleeve 32 is fixedly sleeved inside the through groove, and a groove is provided on the side of the sliding sleeve 32 away from the adapter block 3.

[0023] See also Figure 1-Figure 3 The bottom of the adapter block 3 is provided with a connecting hole, and the top of the fixed block 4 is provided with a hole groove adapted to the connecting hole. The position of the adapter block 3 and the fixed block 4 can be fixed by bolts, and the buffer cylinder 5 is fixedly installed on the other side of the adapter block 3.

[0024] See also Figure 1-Figure 5The interior of the buffer cylinder 5 is located at the inner ring of the sliding sleeve 32 and is slidingly sleeved with a buffer head 51. The buffer head 51 includes a sliding column 511 connected thereto. The sliding column 511 is fixedly connected to the side of the buffer head 51 close to the buffer cylinder 5. The other end of the sliding column 511 is located inside the buffer cylinder 5 and is fixedly connected to a slider 512. A protrusion is provided on the side of the buffer head 51 close to the buffer cylinder 5. The protrusion of the buffer head 51 is adapted to the groove of the sliding sleeve 32. A spring B52 is fixedly connected between the inner wall of the buffer cylinder 5 and the inner wall of the slider 512. A one-way valve 53 is provided throughout the interior of the buffer cylinder 5. The one-way valve 53 is set so that the outside of the buffer cylinder 5 can flow to the inside of the buffer cylinder 5, and the inside of the buffer cylinder 5 cannot flow to the outside of the buffer cylinder 5. A through hole 54 is provided inside the buffer cylinder 5 below the one-way valve 53.

[0025] When the electromagnetic strip 23 contacts the opposite poles of the iron block 31 and is attracted, the user can push open the door fixedly connected to the adapting block 3 and the fixing block 4, and the buffer head 51 is no longer squeezed by the adapting block 12. The spring B52 releases the elastic force to squeeze the buffer head 51 outward from the inside of the buffer cylinder 5. The inside of the buffer cylinder 5 inhales air from the one-way valve 53 and the through hole 54, so that the buffer head 51 is squeezed and released by the spring B52, and the inside of the buffer cylinder 5 is filled with air. When the user leaves, the door rotates toward the direction of the lock body 1 while closing. When it returns to a certain position, the surface of the buffer head 51 will When in contact with the surface of the lock body 1, the inertia generated by the closing of the door will drive the door to rapidly squeeze the buffer head 51. The buffer head 51 will shrink toward the inside of the buffer tube 5 due to the inertia of the door and the pressure from the surface of the lock body 1. The buffer head 51 drives the slider 512 to press the spring B52. Since the one-way valve 53 can only take in but not out, the air inside the buffer tube 5 is squeezed by the slider 512 and will flow out from the through hole 54. Since the diameter of the through hole 54 is too small, the air is output slowly, which plays a buffering role when the door is closed, preventing the door from colliding with the lock body 1 and the lock block 2 when closing.

[0026] Working principle: According to the provided installation holes and positions, the lock body 1 is fixedly installed on the inner side of the door frame, and the combination of the adapter block 3 and the fixing block 4 is fixedly installed on the top position of the door, so that the position of the iron block 31 corresponds to the electromagnetic strip 23. When the electromagnetic strip 23 is energized, it has magnetism and firmly adsorbs the iron block 31. When the user needs to open the door, he uses the corresponding key for identification, so that the electromagnetic strip 23 is temporarily de-energized and the door is pushed inward. After the door is pushed open, the buffer head 51 is no longer squeezed between the adapter block 3 and the adapter block 12, and the buffer head 51 is pushed out from the inside of the buffer cylinder 5 by the spring B52. The buffer cylinder 5 The outside air enters the buffer cylinder 5 through the one-way valve 53 and the through hole 54. When the user enters, the door will automatically rebound and rotate toward the connection. When the door rotates to a certain position, the buffer head 51 contacts the surface of the lock body 1, so that the buffer head 51 is squeezed by the inertia of the door and the lock body 1, causing the buffer head 51 to move quickly into the buffer cylinder 5. However, since the through hole 54 opened inside the buffer cylinder 5 has a small diameter, the air inside the buffer cylinder 5 can only be discharged slowly through the through hole 54, which reduces the inertia of the door closing, avoids the door from hitting the lock body 1 when closing, and extends the life of the access control lock.
