[0016] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0017] like Figures 1 to 4The embodiment of the utility model presented preferably provides a building access control with high security, including an access control device body and a bracket 1, the access control device body includes a front shell 2 and a rear shell 3, the rear shell 3 is installed and connected to the front shell 2 by a first screw, and the end of the first screw faces and is located on the back side of the rear shell 3 relative to the front shell 2, the bracket 1 is installed on the wall by a second screw, and the back side of the access control device body is provided with a hanging part 4 that can be hung and cooperated with the bracket 1, when the hanging part 4 is hung on the bracket 1, the access control device body is covered and hidden on the second screw, the access control device body is provided with a lock core 5, the key hole end of the lock core 5 protrudes outward from the front side of the access control device body, one end of the lock core of the lock core 5 is located on the rear side of the access control device body and is connected to a limit block 6, the limit block 6 is staggered and arranged below the bracket 1 and can movably contact or detach from the lower side of the bracket 1.
[0018] Specifically, the installation connection screws of the front shell and the rear shell are concentrated on the back side of the rear shell, so that when the main body of the access control device is installed on the wall bracket, no screws are exposed on the outside of the main body of the access control device, and the main body of the access control device needs to be removed from the bracket as a whole before the outer shell can be disassembled and maintained; and the main body of the access control device and the bracket bracket are limited by the combination of the lock core, the limit block and the hanging part, and the user needs to use a matching key to remove the main body of the access control device from the bracket, thereby greatly improving the safety of the access control device and better avoiding the risk of illegal personnel destroying the internal electric control system by directly disassembling the shell. When the hanging part is hung on the bracket, the main body of the access control device covers the second screw of the bracket, thereby also avoiding the disadvantage of illegal personnel disassembling the main body of the access control device by disassembling the bracket.
[0019] Furthermore, a hanging part 7 is detachably connected to the back side of the rear shell 3, the hanging part 4 is formed at the lower end of the hanging part 7 by bending, and a cover plate 8 is extended from the upper end of the hanging part 7 toward the front shell 2. Specifically, the cover plate is used to protect the main shell of the access control device, thereby preventing the main shell of the access control device from being damaged and effectively preventing rain.
[0020] Furthermore, the front shell 2 and the rear shell 3 are assembled to form an installation cavity with an upper opening, and the cover plate 8 is placed on the open end of the installation cavity. Specifically, the opening of the installation cavity is closed and covered by the cover plate to effectively reduce the material of the upper end wall of the front shell or the rear shell.
[0021] Furthermore, the lock core 5 includes a lock shell 21 and a lock core 22 rotatably disposed in the lock shell 21, a pin mechanism is connected between the lock shell 21 and the lock core 22, and a key insertion hole and a limit block 6 are respectively disposed at both ends of the lock core 22. Specifically, the pin mechanism is a relatively mature prior art, which can refer to the first pin mechanism or the second pin mechanism in Chinese Patent Publication No. CN215369198U, and then the pin mechanism cooperates with the key to realize the rotational activity or locking fixation of the lock core relative to the lock shell, so as to realize the rotational activity and locking fixation of the limit block, and then when the limit block is in the locked fixed state, the limit block is in a connection state against the lower side of the hanger, at this time, a connection state of clamping the hanger is formed between the limit block and the hanging part, and when the limit block is in the rotational activity state, the limit block rotates to disengage from the interference with the hanger, and the limit block and the hanger are staggered, and then the main body of the access control device can be forced to move upward and disengage from the hanger with the hanging part, so as to realize disassembly.
[0022] Furthermore, the pendant 7 is annular in shape, and a plurality of wiring terminals 9 are arranged on the back side of the rear shell 3 in the inner ring area of the pendant 7 to facilitate subsequent wiring connection.
[0023] Furthermore, when the hanger 1 is installed on the wall, the width of the gap formed between the inner side thereof and the wall is 1 mm-10 mm.
[0024] Furthermore, an LED light area 10 is provided on the lower side of the cover plate 8, so as to facilitate the positioning of the access control device at night and facilitate its use.
