[0029] The anti-falling mechanism 300 includes a braking rod 310, a baffle 330, and an elastic member 350. The braking rod 310 is rotatably connected to the rotating rod 130. The baffle 330 is fixed to the upper end of the braking rod 310. One end of the baffle 330 abuts against the surface of the door panel transmission chain 170. The elastic member 350 is used to drive the braking rod 310 to rotate around the rotating rod 130. A rack 370 is fixed inside the slide rail 110. A braking block 390 is fixed to the lower end of the braking rod 310. The rack 370 is arranged corresponding to the braking block 390.

[0030] In an embodiment of the present invention, it further includes a door frame 190. There are two slide rails 110 arranged in parallel. The two slide rails 110 are symmetrically arranged on the two side walls of the door frame 190. The door panel 100 is arranged between the two slide rails 110. The two slide rails 110 are arranged in parallel and symmetrically installed on the two side walls of the door frame 190, providing horizontal support and guidance for the door panel 100. By smoothly sliding along the slide rail 110 through the pulley 150, it ensures the smooth opening and closing of the door panel 100, and at the same time increases the stability and safety of the door.

[0031] In an embodiment of the present invention, the rotating rods 130 are symmetrically arranged at both ends of the door panel 100. The door panel transmission chains 170 are arranged in one-to-one correspondence with the slide rails 110. The pulleys 150 are arranged in one-to-one correspondence with the rotating rods 130. The rotating rods 130 are arranged in one-to-one correspondence with the slide rails 110. There are multiple door panels 100. The door panel transmission chains 170 are arranged in one-to-one correspondence with the slide rails 110. Through the cooperation of the transmission chain and the slide rail 110, the smooth sliding of the door panel 100 is realized; the pulleys 150 are arranged in one-to-one correspondence with the rotating rods 130. The pulleys 150 rotate on the rotating rods 130, reducing friction and improving the operation efficiency of the door panel 100; at the same time, it ensures the correct positioning of the door panel 100 on the slide rail 110 and prevents deviation.

[0032] In an embodiment of the present invention, a driving mechanism for driving the two door panel transmission chains 170 to move up and down synchronously is installed at the upper end of the door frame 190. The rack 370 extends along the length direction of the slide rail 110. The door frame 190 is designed as the core support structure of the entire door system. A unique driving mechanism is installed on its upper part, which is specifically used to drive the transmission chains 170 on the door panel 100 to move up and down synchronously. The transmission chain 170 not only connects the door panel 100, but also realizes the opening and closing of the door through its movement. The design of the driving mechanism ensures the synchronization of both ends of the door panel 100 during the lifting process, avoiding the problems of jamming or non-synchronization when the door panel 100 is lifted and lowered. In addition, the slide rail 110 arranged along the length direction inside the door frame 190 provides the necessary guidance for the lifting of the door panel 100.

The torsion spring is closely sleeved on the outer surface of the rotating rod 130 and stores elastic potential energy. The first leg of the torsion spring directly abuts against the baffle 330, so that the torsion of the torsion spring drives the brake lever 310 to rotate around the rotating rod 130, and can drive the brake block 390 at the lower end of the brake lever 310 to be clamped with the rack 370 through its elasticity.

[0034] In an embodiment of the present utility model, a sliding sleeve 311 is fixed to the brake lever 310. The sliding sleeve 311 is slidably sleeved on the surface of the rotating rod 130. A clamping groove is formed on the surface of the rotating rod 130. One end of the sliding sleeve 311 is provided with a snap spring, and the snap spring is cooperatively clamped in the clamping groove.

[0035] In an embodiment of the present utility model, the baffle 330 is detachably fixed to the upper end of the brake lever 310, the brake block 390 is detachably fixed to the lower end of the brake lever 310, and the sliding sleeve 311 is arranged between the baffle 330 and the brake block 390; the friction during rotation is reduced by arranging the sliding sleeve 311.

[0036] In an embodiment of the present utility model, a groove for cooperatively inserting the lower end of the brake lever 310 is formed at the upper end of the brake block 390. A screw 391 is threadedly connected to the side wall of the brake block 390, and the other end of the screw 391 abuts against the surface of the brake lever 310. The brake block 390 is designed to cooperate with the brake lever 310 to achieve a fast and effective braking effect. A groove for cooperating with the lower end of the brake lever 310 is formed at the upper end of the brake block 390 to ensure that the two can be closely connected and prevent looseness during braking. In addition, a screw 391 is threadedly connected to the side wall of the brake block 390, and by tightening the screw 391, it is convenient to disassemble and replace the brake block 390.

[0037] In an embodiment of the present utility model, a positioning groove 312 is formed at the upper end of the brake lever 310. One end of the baffle 330 is fitted and inserted into the positioning groove 312. A positioning hole 313 penetrating the brake lever 310 is formed in the inner wall of the positioning groove 312. A limiting hole 331 is formed at one end of the baffle 330. A pin 314 is inserted into the positioning hole 313, and the lower end of the pin 314 is inserted into the limiting hole 331. The upper end of the brake lever 310 is designed with a positioning groove 312 for fixing the baffle 330. One end of the baffle 330 is inserted into the positioning groove 312 and fixed through the cooperation of the positioning hole 313 and the pin 314. The pin 314 passes through the positioning hole 313 and the limiting hole 331 to ensure the stable position of the baffle 330 on the brake lever 310. The connection strength between the brake lever 310 and the baffle 330 is improved, and the installation and disassembly are also facilitated. At the same time, the overall stability and safety of the braking device are ensured.

[0038] In an embodiment of the present utility model, a magnet is fixed at the bottom of the limiting hole 331, and the lower end of the pin 314 is made of a magnetic material or fixed with magnet pieces that attract each other.

[0039] Working principle: The brake lever 310 is rotatably connected to the rotating lever 130. The baffle 330 is fixed at the upper end of the brake lever 310, and one end thereof abuts against the surface of the door panel transmission chain 170 to limit the rotation of the brake lever 310 around the rotating lever 130. The elastic member 350 stores elastic potential energy for driving the brake lever 310 to rotate around the rotating lever 130. A rack 370 is fixed in the slide rail 110, and a brake block 390 is fixed at the lower end of the brake lever 310. The rack 370 and the brake block 390 are arranged corresponding to each other. When the chain breaks, the broken chain loses its binding force on the baffle 330, causing the brake lever 310 to rotate around the rotating lever 130. The brake block 390 at the lower end of the rotated brake lever 310 is clamped with the rack 370 to achieve automatic braking of the door panel 100. The device has a simple structure, a large braking force, and a fast response speed. It can effectively prevent the door panel 100 from falling after the chain breaks, stop the falling door panel 100, and improve the use safety.
