Description

Technical Field

[0001] The utility model relates to the technical field of building access control devices, and particularly relates to a building access control device with quick assembly. Background Art

[0002] As the core device for modern building security management, the building access control system generally adopts an embedded installation method to achieve a flat combination with the wall. In the prior art, the access control host is usually installed through the following steps: First, a metal or plastic frame is embedded in the wall groove, then the host is fixed in the frame by bolts, and finally a decorative cover is covered to hide the bolts and improve the aesthetics. Although this structure can achieve the embedded installation of the access control device, the following significant problems exist in the actual use and maintenance process:

[0003] Most of the existing covers adopt a single-sided snap connection design and are fixed to the host or the frame by plastic snaps. During long-term use, the snaps are prone to breakage due to frequent disassembly or material aging, resulting in the cover being unable to be reliably fixed. In addition, after the snap breaks, the entire cover needs to be replaced, increasing the maintenance cost.

[0004] Strong tool dependence: Disassembly of the host must rely on tools such as screwdrivers, resulting in low efficiency during emergency repairs.

[0005] Risk of rust and thread stripping: Bolts exposed to a humid environment are prone to rust, and repeated disassembly and assembly may cause the threads to strip, making it even impossible to disassemble. Content of the Utility Model

[0037] See Figures 1 - 5 , a quickly assembled building access control device, including a fixed frame 10. A main unit 20 is arranged inside the fixed frame 10. The main unit 20 moves back and forth relative to the fixed frame 10 to be embedded into the fixed frame 10 or detached from the fixed frame 10. It further includes a locking pin 410 and a decorative frame 310. The locking pin 410 is movably arranged relative to the fixed frame 10 and moves between a first position and a second position. When the locking pin 410 is in the second position, the locking pin 410 is coupled and locked with the main unit 20 to restrict the back-and-forth movement of the main unit 20 relative to the fixed frame 10. The decorative frame 310 is movably arranged back and forth relative to the fixed frame 10, and the decorative frame 310 is provided with a driving rod 320 that abuts and drives the locking pin 410. When the decorative frame 310 moves from front to back relative to the fixed frame 10, when it synchronously drives the driving rod 320 to move, it can push the locking pin 410 from the first position to the second position. Compared with the prior art, the decorative frame provided by the present invention not only plays a decorative role but also is used to drive the locking pin to lock the main unit to restrict the front-and-back position of the main unit.

[0038] See Figure 3The host 20 includes a host module 210, the front side of the host module 210 is connected to an operation panel 220, and the host module 210 can be embedded in the fixed frame 10. When in use, the line pre-buried in the wall is connected to the host module 210. The operation panel 220 is set in the decorative frame 310.

[0039] See also Figure 2 , the fixing frame 10 is provided with fixing brackets 120 at intervals in the upper and lower parts, and the host module 210 is fixed between the two fixing brackets 120. During assembly, the host module 210 is inserted into the fixing frame 10, and the left and right sides of the host module 210 are in contact with the inner walls of the left and right sides of the fixing frame 10; the upper and lower sides of the host module 210 are in contact with the fixing brackets 120. The fixing brackets 120 cooperate with the fixing frame 10 to effectively restrict the left and right and up and down movement of the host body 20.

[0040] Furthermore, the fixing bracket 120 is fixedly connected to the fixing frame 10 by using existing detachable connection methods such as bolts or buckles.

[0041] See also Figure 4 The host module 210 is provided with a locking hole 211; when the locking pin 410 moves from the first position to the second position, the locking pin 410 is inserted into the locking hole 211 to restrict the host 20 from moving forward and backward relative to the fixed frame 10. With the restraint of the fixing bracket 120 and the fixed frame 10, the host module 210 can be completely fixed, so that the host body 20 cannot move relative to the fixed frame 10.

[0042] See also Figure 2 and Figure 4 The fixing bracket 120 and the locking pin 410 are connected with an elastic element 430 , and the elastic element 430 is used to drive the locking pin 410 to remain in the first position. When the locking pin 410 is in the first position, the locking pin 410 is separated from the locking hole 211 .

[0043] The driving rod 320 is used to drive the locking pin 410 to move from the first position to the second position. Figure 4 As shown, when the locking pin 410 is located at the second position, the locking pin 410 is inserted into the locking hole 211 .

[0044] Furthermore, the locking pin 410 is provided with a limiting ring 420 . When the locking pin 410 is located at the first position, the limiting ring 420 abuts against the fixing bracket 120 .

[0045] See also Figure 5, guide grooves 110 are provided on the upper and lower wall surfaces of the fixed frame 10, a guiding element 330 is provided on the driving rod 320, and the guiding element 330 is movably inserted into the guide groove 110. This guiding is used to restrict the moving trajectories of the driving rod 320 and the decorative frame 310.

[0046] When the decorative frame 310 moves from front to back, the driving rod 320 first abuts against the locking pin 410. As the decorative frame 310 gradually moves backward, the driving rod 320 drives the locking pin 410 to gradually approach the locking hole 211 until the locking pin 410 is inserted into the locking hole 211. During this process, the elastic element 430 is compressed and stores energy. When the driving rod 320 is separated from the locking pin 410, the elastic element 430 drives the locking pin 410 to reset, that is, to disengage from the locking hole 211 to complete unlocking.

[0047] See Figure 5 , a fitting portion 440 is provided at one end of the locking pin 410 away from the locking hole 211, and the driving rod 320 is in contact with the fitting portion 440; a driving inclined surface 321 is provided at one end of the driving rod 320 facing the fitting portion 440; when the locking pin 410 is in the second position, the driving rod 320 and the fitting portion 440 are in mutual contact. The function of the driving inclined surface 321 is that when the driving rod 320 moves backward, under the guiding action of the inclined surface of the driving inclined surface 321, the fitting portion 440 is extruded to drive the locking pin 410 to move towards the locking hole 211.

[0048] See Figure 5 , a positioning groove 450 is provided on the fitting portion 440, and a positioning protrusion 340 that can be embedded in the positioning groove 450 is provided on the driving rod 320. When the locking pin 410 is in the second position, the positioning protrusion 340 is embedded in the positioning groove 450. The cooperation of the positioning groove 450 and the positioning protrusion 340 can restrict the front-back position of the driving rod 320 and prevent its random movement from causing a change in the position of the locking pin 410. When it is necessary to drive the locking pin 410 to unlock, the decorative frame 310 is pulled forcefully from back to front. During this process, the locking pin 410 moves downward, causing the positioning protrusion 340 to disengage from the positioning groove 450.

[0049] In the present utility model, the elastic element 430 is a spring, and the elastic element 430 is sleeved on the locking pin 410 between the fitting portion 440 and the fixed bracket 120.

[0050] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
