[0030] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0031] Please see Figures 1-6 This utility model provides a security access control device, including an expansion tube 10, an access control housing 100 and a fastening device 01. Through the cooperation of fastening bolts 200, limit component 300, fastening component 400 and fastening component 500, the access control housing 100 is not easily loosened due to vibration.

[0032] An expansion tube 10 for securing the access control housing 100 is installed at the rear end. When installing the expansion tube 10, a cavity is first opened in the wall for placing the expansion tube 10, and then the expansion tube 10 is placed into the cavity.

[0033] The access control housing 100 is equipped with a fastening device 01 for further securing the access control housing 100 in conjunction with the expansion tube 10. The fastening device 01 includes a fastening bolt 200 for supporting the access control housing 100 in conjunction with the expansion tube 10, with one end of the fastening bolt 200 located in the middle of the expansion tube 10. The fastening bolt 200 includes a screw 210, with a threaded end 211 at the left end and a hexagonal groove 212 at the middle of the right end for rotating the screw 210 using an Allen wrench. Rotating the screw 210 with the Allen wrench causes it to move towards the left end of the expansion tube 10, thereby expanding the left end of the expansion tube 10 and tightening the fastening bolt 200. A slider 213 is fixedly installed at the right end of the screw 210, which controls the rotation of the fastening bolt 200 in conjunction with the fastening assembly 500, and the slider 213 slides within the groove of the threaded groove 511. When the expansion tube 10 is inserted into the hole in the wall, the fastening bolt 200 is inserted into the middle of the expansion tube 10, and the fastening bolt 200 is rotated by inserting an internal hexagonal bolt into the groove of the regular hexagonal slot 212, causing the screw 210 to move towards the left end of the expansion tube 10, thereby expanding the left end of the expansion tube 10 and supporting and fastening the access control housing 100.

[0034] The fastening device 01 includes a limiting component 300, which is installed inside the access control housing 100. The limiting component 300 is fixedly disposed in the middle of the fastening bolt 200 and sleeved on the outside of the fastening bolt 200, so that the screw 210 drives the limiting component 300 to move closer to the wall and cooperate with the wall to clamp the access control housing 100, ensuring the stability of the access control housing 100.

[0035] The limiting component 300 includes a limiting post 310, with a sliding groove 311 inside the limiting post 310. One end of the sliding groove 311 has a second sliding groove 312 for the fastening component 400 to slide into. The sliding groove 311 has a retaining groove 313 for limiting the fastening component 400. A spring 320 for controlling the rightward movement of the fastening component 400 is installed inside the groove of the sliding groove 311. When the fastening bolt 200 drives the limiting component 300 to press the access control housing 100 against the wall, the fastening component 400 can be... One end is installed inside the limiting component 300. When installing the fastening component 400, the slider 411 is slid from the groove of the groove 312 into the groove of the groove 311, and the spring 320 is squeezed. Then the limiting post 410 is rotated, so that the limiting post 410 drives the slider 411 to rotate to the left side of the slot 313. The fastening component 400 is released, and under the action of the spring 320, the limiting post 410 is moved to the right, so that the slider 411 is inserted into the groove of the slot 313, thereby locking the fastening component 400.

[0036] The limiting component 300 has a fastening component 400 installed inside, which is used to cooperate with the fastening component 500 to control the fastening bolt 200 to fasten the access control housing 100. The fastening component 400 includes a limiting post 410. The left end of the limiting post 410 is fixedly installed with a slider 411, which is used to limit the fastening component 400 by cooperating with the slot 313. The slider 411 slides from the sliding groove 312 into the cavity of the sliding groove 311 and into the cavity of the slot 313, thus completing the limitation of the fastening component 400. The limiting post 410 has a cavity 412 for the fastening assembly 500 to slide inside. The inner wall of the cavity 412 has a sliding groove 413 for limiting the fastening assembly 500, so that the fastening assembly 500 can slide left and right under the guidance of the sliding groove 413. A spring 420 for controlling the fastening assembly 500 to move to the left is installed at the right end of the cavity 412.

[0037] The fastening device 01 includes a second fastening component 500 for controlling the rotation of the fastening bolt 200. The second fastening component 500 includes a limiting tube 510, which is located inside the cavity 412. The limiting tube 510 has a threaded groove 511 for sliding the slider 213. When the second spring 420 moves the limiting tube 510 to the left, it causes the slider 213 to slide in the groove of the threaded groove 511, which in turn causes the screw 210 to rotate. If the access control housing 100 and the wall become loose due to vibration, the screw 210 will rotate under the guidance of the threaded groove 511, causing the first limiting component 300 to move to the left, thus clamping and securing the access control housing 100 with the wall.

[0038] A limiting block 512 is fixedly installed on the right end of the limiting tube 510. A slider 513 for sliding in the groove of the sliding groove 413 is fixedly installed on the outer wall of the limiting block 512. A connecting rod 514 is fixedly installed on the right end of the limiting block 512 to facilitate the disassembly of the fastening device 01 and the replacement of spring 1 320 and spring 2 420. When replacement is required, the connecting rod 514 is pulled, causing the limiting block 512 to compress spring 2 420, which in turn causes slider 1 213 to slide out of the thread. When the second limiting post 410 is pressed to the left, the second slider 411 slides out of the slot 313, releasing the lock on the second limiting post 410. Then, the first fastening component 400 is rotated so that the second slider 411 is at the left end of the second sliding groove 312. Then, the second limiting post 410 is moved to the right to facilitate the disassembly of the first fastening component 400, so that the first spring 320 can be replaced. Then, the second fastening component 500 can be taken out from the cavity 412 and the second spring 420 can be replaced.

[0039] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
