In this embodiment, the support base 104 and the door rod assembly 200 are arranged in pairs, the door rod assembly 200 can be lifted, the guard rail 201, the lower cross bar 202 and the connecting rod 203 are connected in a diamond shape, the vertical distance between the guard rail 201 and the lower cross bar 202 can be changed, and the position of the connecting rod 203 is changed accordingly, so that the door rod assembly 200 can be lifted. The connecting structure of the connecting rod 203, the guard rail 201 and the lower cross bar 202 is the prior art and is not described in detail.
The side surface of the supporting seat 104 is provided with a containing groove 101, the bottom of the containing groove 101 is provided with a driving chamber 102, and the containing groove 101 is communicated with the outside through a shaft hole 103;

the transmission shaft 201a is disposed in the shaft hole 103, the deceleration block 201b is disposed in the receiving groove 101, and the driving member 201c is fixedly disposed in the driving chamber 102.
The driving member 201c is a stepping motor, and is used to control the transmission shaft 201a and the guard rail 201 to rotate within a certain angle, that is, to realize the lifting and opening or the lowering and closing of the door rod assembly 200.
The fault-tolerant assembly 300 comprises a conversion disc 301 and ratchet teeth 302 arranged on the inner side wall of the accommodating groove 101, wherein the conversion disc 301 is sleeved on the transmission shaft 201a, and the conversion disc 301 is arranged in the accommodating groove 101.
A groove 301a is formed in the conversion disc 301, an arc-shaped limiting plate 101a is arranged on one side face of the accommodating groove 101, and the arc-shaped limiting plate 101a is embedded in the groove 301 a;
the arc-shaped limiting plate 101a is provided with a fan-shaped notch 101b, and the deceleration block 201b is arranged in the fan-shaped notch 101 b.
The circumferential wall of the inner side of the groove 301a is provided with a first reduction tooth 301b, the outer circumferential surface of the reduction block 201b is provided with a second reduction tooth 201d, and the first reduction tooth 301b is matched and connected with the second reduction tooth 201 d.
A first caulking groove 301c is formed in the outer circumferential surface of the conversion disc 301, a pawl 301d connected with a side wall shaft of the first caulking groove 301c is arranged in the first caulking groove 301c, and a first spring 301e connected with the pawl 301d is further arranged in the first caulking groove 301 c;
the pawl 301d is matingly connected to the ratchet teeth 302.
The pawl 301d is rotatable and the first spring 301e tends to push the pawl 301d out of the first nest 301c, bringing the pawl 301d into contact with the ratchet teeth 302.
The first spring 301e makes the pawl 301d at a position of contacting and engaging with the ratchet teeth 302, when the conversion disk 301 rotates clockwise as shown in fig. 4, the pawl 301d contacts with the ratchet teeth 302 and is pressed to rotate, the first spring 301e compresses, the pawl 301d is pressed into the first caulking groove 301c, and at this time, the conversion disk 301 can smoothly rotate relative to the ratchet teeth 302; when the switching disk 301 is rotated counterclockwise as shown in fig. 4, the pawls 301d engage with the ratchet teeth 302, and the switching disk 301 is restricted from rotating with respect to the ratchet teeth 302.
A second caulking groove 301f is formed in the bottom surface of the groove 301a, a clamping block 301g connected with a side wall shaft of the second caulking groove 301f is arranged in the second caulking groove 301f, and a second spring 301h connected with the clamping block 301g is arranged in the second caulking groove 301 f.
The latch 301g in the groove 301a is not pressed, and the end of the latch 301g is in the groove 301a in a natural state.
The latch 301g is rotatable with its end portion extending beyond the second indent 301f and also rotatable to be fully engaged in the second indent 301f, and the second spring 301h tends to cause the end portion of the latch 301g to extend beyond the second indent 301f, i.e., to cause the end portion of the latch 301g to be positioned in the recess 301 a.
It should be noted that the latch 301g is disposed near one end of the second insertion groove 301f, so that the latch 301g can be inserted into the second insertion groove 301f only from one direction. As shown in fig. 4, when the deceleration block 201B rotates counterclockwise in the sector notch 101B from the position B to the position a, the deceleration block 201B pushes the latch 301g to deform the second spring 301h, so as to press the latch 301g into the second slot 301f, and the deceleration block 201B rotates in the groove 301a relative to the switching disk 301.
When the latch 301g rotates clockwise in the fan-shaped notch 101B from the position a to the position B, the deceleration block 201B cannot press the latch 301g into the second slot 301f, and the deceleration block 201B is blocked by the latch 301g to push the latch 301g to drive the switching disc 301 to rotate together.
It should be noted that when the deceleration block 201B is located at a, it corresponds to the case where (1) the door lever assembly 200 in fig. 1 is closed when being lowered, and (2) the door lever assembly 200 in fig. 1 is opened when the deceleration block 201B is located at B when being lifted.
The teeth of the first and second decelerating teeth 301b and 201d are semi-cylindrical, and it should be noted that the first and second decelerating teeth 301b and 201d are in interference fit.
The second caulking grooves 301f are arranged at the bottom of the groove 301a along the circumferential array of the transmission shaft 201 a.
The invention can lead the protective guard 201 to slowly fall when falling under the condition of not being controlled by a motor, thereby avoiding the injury caused by smashing personnel.
Specifically, during the lifting process of the guard rail 201, that is, the motor drives the transmission shaft 201a to rotate, so that when the deceleration block 201B moves from a to B, the deceleration block 201B pushes the latch 301g to rotate the switching disc 301 together, and at this time, the pawl 301d on the outer side of the switching disc 301 is pressed into the first caulking groove 301c, and at this time, the switching disc 301 can smoothly rotate relative to the ratchet teeth 302 to realize the lifting, which is not hindered.
When a fault occurs, the protective guard 201 falls, that is, the deceleration block 201B rotates from the position B to the position a counterclockwise in the fan-shaped notch 101B, the conversion plate 301 cannot rotate relative to the ratchet teeth 302 under the clamping action of the pawls 301d and the ratchet teeth 302, and the deceleration block 201B pushes the fixture block 301g to deform the second spring 301h, so that the fixture block 301g is pressed into the second caulking groove 301f, and the deceleration block 201B rotates relative to the conversion plate 301 in the groove 301a, so that the protective guard 201 descends; in the process, the first decelerating teeth 301b and the second decelerating teeth 201d move relatively, and due to the matching effect between the first decelerating teeth 301b and the second decelerating teeth 201d, the second decelerating teeth 201d can be subjected to certain resistance relative to the rotation of the first decelerating teeth 301b, so that the protective guard 201 slowly descends under the action of self gravity, the risk of injury to people is avoided, and the door is kept closed in a protective state.
