DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0028] Please refer to Figures 1-5 The utility model provides a technical scheme: a secret room door structure with hidden locking structure, including door frame 1, rotating installation on door frame 1 door body 2, install on the free end of door body 2 door lock 201, install the rotating lock piece 202 of door lock 201 rear end and open in door frame 1 with rotating lock piece 202 corresponding first lock groove 101, door body 2 and door frame 1 between with door lock 201 between cooperation effect to promote the secret room door anti-theft effect of internal locking mechanism.
[0029] Specifically, as Figures 1-4 Indicated, internal locking mechanism includes rotating installation in the front end of door body 2 near door lock 201 position rotating disc 3, fixed in the rear end of rotating disc 3 and the locking state is the vertical distribution oval rotating block 302, open in the rear end of door body 2 and be located in the upper and lower sides of rotating disc 3 vertical sliding groove 204, movable installation in the inner side of vertical sliding groove 204 and the inner end with oval rotating block 302 abutment sliding lock block 4 and open in door frame 1 with sliding lock block 4 outer end and lock second lock groove 102.
[0030] A limiting block 5 is installed at the rear end of the door body 2, which passes through the sliding block 4. The sliding block 4 is provided with a limiting groove 401 for accommodating the limiting block 5. The setting of the limiting block 5 and the limiting groove 401 improves the stability of the sliding block 4 in the vertical sliding groove 204 and can reduce the occurrence of the sliding block 4 shifting, shaking and abnormal noise in the vertical sliding groove 204. A spiral compression spring 6 is installed between the limiting groove 401 and the limiting block 5. Under normal conditions, it applies an inward elastic compression force to the sliding block 4, so that the inner end of the sliding block 4 can always abut against the outer wall of the elliptical rotating block 302. Thus, by rotating and adjusting the elliptical rotating block 302, the position distribution of the two sliding blocks 4 can be adjusted to realize the locking or unlocking of the sliding block 4 and the second locking groove 102.
[0031] A secondary lock 203 is fixedly connected to one end of the rotary lock 202 facing the elliptical rotary block 302. The outer end of the secondary lock 203 can abut against the outer wall of the elliptical rotary block 302. When the rotary lock 202 is in a horizontal state, it can be locked in the first lock groove 101 of the door frame 1. At the same time, the secondary lock 203 can abut against the outer wall of the elliptical rotary block 302, thereby preventing the elliptical rotary block 302 from rotating, thus performing rotation locking on the rotary disc 3 and the handle 301.
[0032] The front end of the rotary disc 3 is fixedly connected to a handle 301 that is parallel to the elliptical rotary block 302, which facilitates the operator's gripping and rotation adjustment of the rotary disc 3. In actual manufacturing and protective use, a hidden handle 301 structure can be selected. When not in use, the handle 301 can be hidden and stored inside the rotary disc 3, so that the door 2 and the rotary disc 3 form a planar structure, which can improve the protection and anti-theft effect of the door 2. However, this hidden handle 301 structure will increase the workload and difficulty for the user to open the secret room door in actual operation.
