Description

Technical Field

[0001] This utility model relates to the field of prison door technology, and in particular to an anti-derailment electric sliding prison door. Background Technology

[0002] Electric sliding prison doors are widely used in judicial supervision facilities. They feature high-strength protection, with the door body typically made of galvanized steel plates thicker than 1.5mm and reinforced internally with 40×40×2mm galvanized square tubing. They also have high impact resistance, capable of withstanding human sabotage and impacts under extreme conditions.

[0003] The problems compared with existing technologies are as follows: Most existing sliding prison doors use rigid sliding connections for their moving structure. Under violent impact, the rollers and their supports are prone to deformation, which may cause the door to derail, affecting the safety of the prison door during use and making it impractical. To address these issues, we propose an anti-derailment electric sliding prison door. Utility Model Content

Multiple support rollers 560 are rotatably connected to the top of the mounting cross plate 550 via a pivot pin. A mounting slide rail 570 is rotatably connected to the outer side of the support rollers 560. The mounting slide rail 570 is fixedly connected to the door frame 100. An opening and closing mechanism is provided. The main door 220 is suspended by a suspension mechanism, and the main door 220 is driven to slide on the inner wall of the door frame 100 by a moving mechanism, realizing the automatic opening and closing of the main door 220. During the process, the bottom of the main door 220 is buffered and protected by the support mechanism to prevent the main door 220 from derailing, thereby improving the safety of the prison door during use and thus improving the practicality of the prison door.

[0032] Specifically, a sealing cover A111 is fixed to the top of the support base 110, and a sealing cover B130 is fixed to the top edge of the door frame 100. The sealing cover A111 can protect the top of the support mechanism from dust and debris, and the sealing cover B130 can protect the bottom of the suspension mechanism and the moving mechanism from dust and debris, thus ensuring the stability of the prison door.

[0033] Specifically, a handle 230 is fixed on one side of the main door body 220, and an electronic lock assembly 240 is provided on the inner wall of the main door body 220; the main door body 220 is locked by the electronic lock assembly 240, and the handle 230 facilitates pushing and pulling of the main door body 220.

[0034] Specifically, the suspension mechanism includes a mounting bracket A310, which is fixed to the top of the door frame 100 by bolts.

The sealing cover B130 protects the bottom of the suspension and moving mechanisms, ensuring stability. The mounting bracket A310 is suspended from the mounting rail A330 by the hanging rollers 320, allowing for the suspension of the main door body 220. The reduction motor 420 drives the drive shaft 421, which in turn drives the drive pulley 430. The drive pulley 430, via the transmission belt 431, drives the driven pulley 440. The driven pulley 440 is connected to the connecting shaft... 441 drives the drive gear 450 to rotate, and the drive gear 450 rolls on the rack 460, thereby driving the main door body 220 to slide on the inner wall of the door frame 100, realizing the opening and closing operation of the main door body 220. The main door body 220 is locked by the electronic lock assembly 240, and the main door body 220 can be pushed and pulled by the handle 230. During the process, the support roller 560 rolls on the mounting slide rail 570, and the limiting slide 530 is elastically telescopically connected to the sliding seat 520 through the damping rod 540. When the main door body 220 is impacted, the suspension mechanism resists the impact on the top of the main door body 220, and the damping rod 540 buffers the impact force, which can reduce the impact force on the mounting plate 550 and the support roller 560, and buffer and protect the mounting slide rail 570 and the bottom of the main door body 220 to prevent the main door body 220 from derailing.
