[0039] See Figure 1 and Figure 2 The push-in rigid anti-theft door shown includes a fingerprint lock 3, a door frame system 1 and a steel door 2, the door frame system 1 includes a first door frame strip 101, a second door frame strip 102 and a door top plate 103, the door top plate 103 is fixedly installed between the first door frame strip 101 and the second door frame strip 102, the steel door 2 is matched between the first door frame strip 101 and the second door frame strip 102, a passive sliding device and an active driving device are matched between the second door frame strip 102 and the steel door 2, under the action of the passive sliding device and the active driving device, the steel door 2 slides translationally between the first door frame strip 101 and the second door frame strip 102, the steel door 2 is respectively matched with a connecting piece 21 between the passive sliding device and the active driving device, the fingerprint lock 3 is installed on the steel door 2, and the lock tongue of the fingerprint lock 3 matches the first door frame strip 101.

[0040] In the above technical solution, when the steel door 2 is pushed between the first door frame bar 101 and the second door frame bar 102, the first door frame bar 101 clamps the steel door 2, so that the steel door 2 cannot rotate along the hinge position, thereby playing an anti-theft role.

[0041] See Figure 3 As shown, the first door frame strip 101 is provided with a first right-angle groove 111 on the side opposite to the second door frame strip 102, and the second door frame strip 102 is provided with a second right-angle groove 112 on the side opposite to the first door frame strip 101. The steel door 2 is limited by the right-angle surfaces of the first right-angle groove 111 and the second right-angle groove 112. The right-angle surface of the first right-angle groove 111 forms a limit for the rotation of the steel door 2. A third right-angle groove 113 is provided in front of the first right-angle groove 111. When the steel door 2 is translated to the position of the third right-angle groove 113, the rotation restriction of the steel door 2 is released, and a lock hole for the lock tongue of the fingerprint lock 3 is processed on the groove wall of the first right-angle groove 111.

[0042] The first right-angle groove 111 and the second right-angle groove 112 cooperate to form a limit on the closed position of the steel door 2. Secondly, after closing, the steel door 2 is pushed into the first right-angle groove 111, and the groove wall of the first right-angle groove 111 clamps the steel door 2, making it impossible for the steel door 2 to be rotated open.

[0043] When opening the door normally, the steel door 2 is moved to the position of the third right-angle groove 113 and can be rotated and opened normally.

[0044] See Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 11 As shown, the active drive device includes a motor 41, which is built into the second door frame strip 102, and a drive shaft 42 is longitudinally inserted into the second door frame strip 102. A bearing 43 is provided between the drive shaft 42 and the second door frame strip 102, and the drive shaft 42 passes through the right-angle surface of the second right-angle groove 112. The part of the drive shaft 42 located in the second right-angle groove 112 is processed with a drive thread 44. A passive bevel gear 45 is fixedly installed at the position of the drive shaft 42 located in the second door frame strip 102, and an active bevel gear 46 is installed on the output shaft of the motor 41. The active bevel gear 46 is meshed with the passive bevel gear 45, and a first slider 47 is provided through the drive shaft 42. The first slider 47 has a matching The threaded hole 48 is matched with the driving thread 44, and the first threaded holes 49 are correspondingly processed at the upper and lower ends of the first slider 47. The connecting piece 21 is fixed to the steel door 2, and the end of the connecting piece 21 away from the steel door 2 is provided with two support arms 22, and the end of the support arm 22 is provided with a connecting sleeve 23. The first slider 47 is located between the two support arms 22, and the connecting sleeve 23 corresponds to the first threaded hole 49. A positioning shaft 410 is screwed into the upper and lower ends of the first slider 47, and the positioning shaft 410 has a threaded section 411 that matches the first threaded hole 49. The end of the positioning shaft 410 away from the threaded section 411 is provided with a limited end 412. The positioning shaft 410 is inserted into the connecting sleeve 23 and provides rotational support for the connecting sleeve 23.

[0045] In the above technical solution, the motor 41 is linked to the fingerprint lock 3. When the fingerprint lock 3 is unlocked, the motor 41 drives the drive shaft 42 to rotate. At this time, the first slider 47 moves forward, driving the door body 2 to move forward and disengage from the first right-angle groove 111. At this time, the steel door 2 can be pushed open.

[0046] When the door needs to be closed, push the steel door 2 in the direction of closing. When it is pushed to the limit position, press the handle of the fingerprint lock 3. At this time, the motor 41 drives the first slider 47 to move backward, driving the steel door 2 to move horizontally into the first right-angle groove 111. After it is in place, release the handle of the fingerprint lock to close the door.

[0047] See Figure 4 、 Figure 8 、 Figure 9 and Figure 10 As shown, the passive sliding device includes a sliding shaft 51, which is parallel to the driving shaft 42. The sliding shaft 51 is fixed on the right-angle surface of the second right-angle groove 112, and a second slider 52 is matched with the sliding shaft 51. The second slider 52 has a sliding hole 53 passing through the sliding shaft 51, and the upper and lower ends of the second slider 52 are processed with coaxial second threaded holes 54. The connecting sleeve 23 corresponds to the second threaded hole 54, and the threaded section 411 cooperates with the second threaded hole 54; the side of the second slider 52 is provided with a limiting plate 520 for limiting the rotation of the connecting member 21, and a shock-absorbing pad 521 is provided on the plate surface of the limiting plate 520.

[0048] The above technical solution mainly supports the movement of the steel door 2 and reduces the load on the drive shaft 42.

[0049] See Figure 6 As shown, a stepped hole corresponding to the drive shaft 42 is processed at the rear end surface of the second door frame strip 102, and a cover plate 122 is detachably fitted in the stepped hole. A polygonal force-bearing hole 4442 is processed at the rear end of the drive shaft 42.

[0050] In the case that the motor 41 is damaged and the door cannot be opened from the outside, the cover plate 122 can be removed, and then a tool can be inserted into the force-bearing hole 4442, and the drive shaft 42 can be manually rotated to realize emergency door opening.

[0051] To be on the safe side, the stress-bearing hole 4442 can be designed into a special polygon.

[0052] See Figure 5 As shown, the steel door 2 includes a frame-shaped inner frame 201 and a door body 202 covered on the outside of the inner frame 201. Bolts 203 are provided between the inner frame 201 and the connecting member 21. The bolts 203 pass through the door body 202. The lock core of the fingerprint lock 3 is installed on the inner side of the inner frame 201, and the panel of the fingerprint lock 3 is installed through the door body 202.

[0053] In the above technical solution, the inner frame 201 is a steel frame with a welded structure, which increases the overall strength of the steel door.

[0054] See Figure 5 and Figure 6 As shown, a reinforcing steel plate 204 is welded on the inner side of the inner frame 201 , and a slot is cut in the reinforcing steel plate 204 at a position corresponding to the lock core of the fingerprint lock 3 .

[0055] The use of the reinforcing steel plate 204 can enhance the puncture-proof capability of the device.

[0056] See Figure 5 As shown, a reinforcing steel pipe 2231 is welded to the rear end of the reinforcing steel plate 204 , and the reinforcing steel pipe 2231 abuts against the inner wall of the door body 202 .

[0057] The provision of the reinforced steel pipe 2231 can increase the ability of the door body 202 to withstand external forces.

[0058] See Figure 1 and Figure 5 As shown, a frame-shaped water pipe 2232 is welded at the front end of the reinforcing steel plate 204, and the water pipe 2232 and the door body 202 are sealed with glue. A water spray hole 2233 is drilled at the front end surface of the door body 202, and the water spray hole 2233 is connected to the water pipe 2232. The water pipe 2232 is equipped with a water inlet pipe 2234, and the rear end of the water inlet pipe 2234 passes through the door body 202 and is equipped with a plug 2235.

[0059] When a fire occurs indoors, it takes time for firefighters to unlock the door. Therefore, emergency water injection can be carried out through the water inlet pipe 2234. Water is injected into the room through the water spray hole 2233 to form a fire protection area at the door body position, providing certain assistance to indoor occupants in escaping. Secondly, this method can reduce the temperature of the door body 2, making it easier to open the door.

[0060] See Figure 5 As shown, an outer frame 2323 is provided at the rear end of the door body 202 , and the outer frame 2323 is respectively attached to the first door frame strip 101 and the second door frame strip 102 .
