As shown in fig. 3, the double-layer door 2 is formed by splicing a first layer plate 21 and a second layer plate 25, a cavity is formed inside the first layer plate 21 and the second layer plate 25, an anti-riot mechanism is assembled in the cavity, the anti-riot mechanism is composed of a thorn plate 23, a first reaction package 24, a second reaction package 26 and a second cone thorn 27, the first cone thorn and the first reaction package 24 are uniformly distributed on the thorn plate 23, the second reaction package 26 and the second cone thorn 27 are uniformly distributed on the inner wall of the second layer plate 25, the second reaction package 26 and the second cone thorn 27 are distributed in a staggered manner, the first cone thorn and the second reaction package 26 are opposite, the first reaction package 24 and the second reaction package 26 can be filled with irritant gas or anesthetic gas, etc., when the second layer plate 25 is violently impacted, the first cone thorn and the second cone thorn 27 can respectively pierce the first reaction package 24 and the second reaction package 26, reactants in the first reaction package 24 and the second reaction package 26 are respectively and discharged into the vent groove from the vent groove, the action monitoring chamber is reduced, the first reaction package 24 and the second reaction package 26 can penetrate the door frame 2, the side face of the door frame is shielded by the sealing strip 1, the sealing strip is prevented from leaking out, the door frame 1, and the door frame 1, the door frame is blocked by the sealing strip 1.

Further, as shown in fig. 2, one side that first plywood 21 deviates from second plywood 25 is embedded to have shrouding 22, and shrouding 22 passes through bolt and first plywood 21 fixed connection, and thorn board 23 fixes on shrouding 22, and shrouding 22 maintains the inside anti-riot mechanism of double-layer door 2 with the split type structural design of first plywood 21, the convenient dismouting.

As shown in fig. 3-5, the first core 3 is fixed between the first layer board 21 and the second layer board 25, a reverse self-locking mechanism 4 is disposed at one end of the first core 3 away from the double-layer door 2, the reverse self-locking mechanism 4 includes a sleeve 41, the sleeve 41 is fixed on an inner wall of the door frame 1, a bolt of the first core 3 can penetrate through the door frame 1 and be inserted into the sleeve 41, a push-pull block 42 is inserted into the sleeve 41, upper and lower ends of the push-pull block 42 are hinged to a push-pull rod 43 through a hinge shaft, connecting shafts 44 are fixed on two sides of a middle portion of the push-pull rod 43, the push-pull rod 43 is rotatably connected to the door frame 1 through the connecting shafts 44, a lock pin 45 is movably connected to one end of the push-pull block 43 away from the push-pull block 42 through a rotating shaft, the lock pin 45 penetrates through the inner wall of the door frame 1, a spring 46 is sleeved on an outer surface of the lock pin 45, lock slots are formed on the upper and lower sides of the first core 3, the two lock slots are respectively matched with the lock pin 45, when the bolt in the push-pull block 42 in the first core 3 pushes the push-pull block 43 to rotate around the center, the door frame, the lock pin 43, the lock bolt is inserted into the double-pull door frame 2, and the double-pull door frame, thereby forming a double-layer door, and a two-lock effect of the double-layer door 2.

Further, as shown in fig. 5, two ends of the push-pull rod 43 are both provided with a waist circular groove, a hinge shaft connecting the push-pull block 42 and the push-pull rod 43 is slidably connected with the first waist circular groove, and a rotating shaft connecting the push-pull rod 43 and the lock pin 45 is slidably connected with the second waist circular groove, so that when the push-pull rod 43 rotates, a moving space is formed between the hinge shaft and the rotating shaft connecting the push-pull block 43, the push-pull block 42 and the lock pin 45.

Further, as shown in fig. 3, a connecting block is uniformly fixed on the surface of the first layer plate 21 connected with the second layer plate 25, a connecting groove matched with the connecting block is formed in the surface of the second layer plate 25 connected with the first layer plate 21, the connecting block and the connecting groove are inserted and fixed, a bolt is inserted into the side surface of the second layer plate 25, the bolt penetrates through the connecting block and is connected with the second layer plate 25 through threads, and the first layer plate 21 and the second layer plate 25 are conveniently connected and assembled in a connecting mode.

The working principle is as follows: when the double-layer door 2 is closed on the door frame 1, the lock tongue in the first lock cylinder 3 can be inserted into the sleeve 41 to push the push-pull block 42, so that the push-pull block 42 pulls one end of the push-pull rod 43 to be far away from the double-layer door 2, and the other end of the push-pull rod 43 can push the lock pin 45 to be inserted into the lock groove on the side surface of the double-layer door 2, thereby forming bidirectional locking.

When the double-layer door 2 is opened, the lock tongue of the first lock core 3 is far away from the push-pull block 42, and the lock pin 45 is applied by the resilience force of the spring 46, so that the lock pin 45 can return back into the doorframe 1.

When a prisoner beats the second laminate 25 from the prison room and the force is applied to damage the double-layer door 2, the second laminate 25 is pressed to drive the second cone 27 and the second reaction bag 26 to extrude towards the thorn plate 23 and the first reaction bag 24 respectively, so that the first reaction bag 24 and the second reaction bag 26 are punctured, the ammonia gas and the hydrogen chloride in the first reaction bag 24 and the second reaction bag 26 respectively leak and react in a mixing way, and a large amount of smoke can be generated and discharged into the prison room from the vent groove to press the prisoner.

As shown in fig. 7-9, example two: the second embodiment is based on the first embodiment, and is different in that the surface of the lock pin 45 in the second embodiment does not have the spring 46, the spring 46 is sleeved on the push-pull block 42, two ends of the spring 46 respectively abut against the sleeve 41 and the push-pull block 42, the side surface of the push-pull block 42 abuts against the cam 6, a clamping groove matched with the top end of the cam 6 is formed in one side of the push-pull block 42 abutting against the cam 6, the second lock cylinder 5 is arranged in front of the cam 6, the second lock cylinder 5 is fixed on the door frame 1, the output end of the second lock cylinder 5 is connected with the bottom of the cam 6 through a ratchet wheel, when the key matched with the second lock cylinder 5 is used for clockwise screwing the second lock cylinder 5 until the second lock cylinder is screwed in place, the second lock cylinder 5 can drive the cam 6 to rotate clockwise through the ratchet wheel, when no key exists in the second lock cylinder 5, the ratchet wheel can rotate anticlockwise, so that the lock tongue does not affect the lock tongue to push-pull block 42 to drive the lock pin 45 to be inserted into the lock groove, when locking, the key is not needed, only when the unlocking, the convenience is achieved, and the safety is further improved.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
