If the webbing is of normal thickness, the airflow will be dispersed by the webbing and cannot be blown directly into the ventilation hole 8 to trigger the reminder mechanism. If the webbing has a gap or is thin, the airflow will blow directly into the ventilation hole to trigger the reminder mechanism. This device is simple to operate and has a low manufacturing cost.

[0039] like Figure 3 As shown, an active cavity 17 is opened near the inner side of the side panel 2, the bottom of the active cavity 17 is connected with the driving groove 3, the active cavity 17 is connected with the slide cavity 9 through the connecting hole 18, the connecting rod 12 is arranged through the connecting hole 18, and the vertical tube 14 slides inside the active cavity 17.

[0040] like Fig.10 As shown, the driving mechanism includes a push rod cavity 19, which is opened at the top of the side of the connecting hole 18 away from the feeding end of the bottom plate 1, and a push rod 21 is slidably installed inside the push rod cavity 19 through a fourth spring 20. A limiting slide groove 22 is opened on the side of the push rod cavity 19, and a limiting slider 23 is fixedly installed on the end of the side of the push rod 21 away from the connecting hole 18, and the limiting slider 23 slides in the limiting slide groove 22.

[0041] like Figure 4 and Fig.10As shown, a vertical sliding cavity 24 is provided at the top of the connecting hole 18 near the push rod cavity 19, a blocking plate 26 is slidably installed inside the vertical sliding cavity 24 through a fifth spring 25, and the bottom end of the blocking plate 26 extends into the connecting hole 18. One end of the push rod cavity 19 away from the connecting hole 18 is connected to one end of the vertical sliding cavity 24 away from the connecting hole 18 through a first rope threading hole 27, and a first pull rope 28 is provided inside the first rope threading hole 27. The two ends of the first pull rope 28 are respectively connected to one end of the push rod 21 away from the connecting hole 18 and one end of the blocking plate 26 away from the connecting hole 18. The end of the push rod cavity 19 away from the connecting hole 18 is also connected to the slide plate cavity 9 through a second rope threading hole 29, and the end of the push rod 21 away from the connecting hole 18 is connected to the lifting slide plate The bottom end of 4 is connected by a second pull rope 30, and the second pull rope 30 is passed through the second rope threading hole 29; the lifting slide 4 rises and drives the connecting rod 12 to rise, pushing the blocking plate 26 to rise, wherein when the lifting slide 4 rises, the second pull rope 30 will be released, and the push rod 21 will be released. When the blocking plate 26 rises, the first pull rope 28 will be released, and the push rod 21 will be released. The push rod 21 is unlocked, but at this time the push rod 21 is blocked by the blocking plate 26 and cannot pop out. When the blocking plate 26 is pushed into the vertical sliding cavity 24 by the connecting rod 12, the push rod 21 pops out and shocks the connecting rod 12, wherein the elastic force of the second spring 13 is less than the elastic force of the fourth spring 20. When the lifting slide 4 descends, the push rod 21 will be pulled into the push rod cavity 19, and then the blocking plate 26 is pushed down by the fifth spring 25.

[0042] like Fig.10 As shown, a magnet 31 is embedded on the side of the connecting hole 18 away from the push rod cavity 19, and an iron plate 32 matching the magnet 31 is embedded on the side of the connecting rod 12 close to the magnet 31; after the connecting rod 12 is bounced off by the push rod 21, the connecting rod 12 squeezes the second spring 13 in the horizontal slide groove 11 to slide, and the iron plate 32 is attracted by the magnet 31. When the lifting slide plate 4 descends, the iron plate 32 slides on the magnet 31 until the iron plate 32 is separated from the magnet 31, and the connecting rod 12 begins to reset under the elastic force of the second spring 13.

[0043] like Figure 7 and Fig.10 As shown, a sensing sheet 33 is provided on the side of the connecting rod 12 away from the second spring 13, a sensing switch 34 is provided on the end of the push rod 21 close to the connecting hole 18, and a delay switch 35 is provided on the bottom end of the connecting hole 18 close to the push rod 21. Both the sensing switch 34 and the delay switch 35 are connected to the electric telescopic rod 10. By providing the sensing switch 34 and the delay switch 35 connected to the electric telescopic rod 10, when the lifting slide plate 4 rises, when the sensing sheet 33 is sensed by the sensing switch 34, the electric telescopic rod 10 starts to slowly descend. When the connecting rod 12 is reset under the action of the second spring 13, the delay switch 35 senses the sensing sheet 33. After a certain period of time, the electric telescopic rod 10 starts to drive the lifting slide plate 4 to rise. This setting can make the device run automatically and is easy to operate.

[0044] like Figure 5 As shown, the reminder mechanism includes a fan blade 36, which is rotatably installed on the side of the ventilation hole 8 through a fan blade shaft 37, and part of the fan blade 36 extends into the ventilation hole 8; when the air flow passes through the weaker part or the notched position of the webbing and blows directly into the ventilation hole 8, it will blow the fan blade 36, causing the fan blade 36 and the fan blade shaft 37 to rotate.

[0045] like Figure 1 and Figure 5 As shown, a slider cavity 38 is opened inside the bottom plate 1, and the slider cavity 38 is connected with the blade shaft 37 through a third rope threading hole 39. A pulling slider 40 is slidably installed inside the slider cavity 38. A third pull rope 41 is fixedly installed on the end of the pulling slider 40 close to the blade shaft 37. The other end of the third pull rope 41 passes through the third rope threading hole 39 and is wound on the blade shaft 37. The end of the pulling slider 40 away from the third pull rope 41 is connected to the end of the slider cavity 38 away from the third pull rope 41 through a first spring 42. A first button 43 is provided at the end of the slider cavity 38 close to the blade shaft 37, and a buzzer is provided on the mounting plate 5. The device 44 is connected to the first button 43; by setting a pulling slider 40 connected to the fan blade shaft 37, and setting a first button 43 connected to the buzzer 44 in the slider cavity 38, when the airflow blows the fan blade 36 to rotate, the fan blade shaft 37 will wind the third pull rope 41, thereby pulling the pulling slider 40 to slide and squeeze the first button 43, so that the buzzer 44 alarms, which is convenient for discovering defective webbing. When the airflow entering the ventilation hole 8 disappears, the first spring 42 pulls the pulling slider 40 to reset. At this time, the fan blade shaft 37 will also reverse under the action of the third pull rope 41.

[0046] Working principle:

[0047] Before the equipment works, the two sides of the webbing are placed in the two driving grooves 3 respectively, and then the lifting slide 4 is controlled by the electric telescopic rod 10 to slide back and forth up and down. When the lifting slide 4 rises, it drives the connecting rod 12 to rise, and the connecting rod 12 pushes the blocking plate 26 to rise. When the lifting slide 4 rises, the second pull rope 30 will be released at the same time, and the push rod 21 will be released for the first time. When the blocking plate 26 is pushed up, the first pull rope 28 will be released, and the push rod 21 will be released again. The push rod 21 is completely unlocked, but at this time the push rod 21 is blocked by the blocking plate 26. The plug 26 cannot be ejected. When the plug 26 is pushed into the vertical sliding cavity 24 by the connecting rod 12, the push rod 21 pops out and shocks the connecting rod 12, so that the connecting rod 12 squeezes the second spring 13 and slides in the horizontal sliding groove 11 until the iron plate 32 is attracted by the magnet 31. When the induction sheet 33 on the connecting rod 12 is sensed by the induction switch 34, the electric telescopic rod 10 begins to slowly descend. When the lifting slide 4 descends, the iron plate 32 causes the connecting rod 12 to slide close to the magnet 31 under the attraction of the magnet 31. When the connecting rod 12 is connected After the inner slider 16 abuts against the webbing, the iron plate 32 follows the connecting rod 12 to slide out of the attraction range of the magnet 31, and the connecting rod 12 begins to reset under the elastic force of the second spring 13. While the connecting rod 12 resets, it drives the webbing to slide a certain distance through the inner slider 16. When the lifting slide plate 4 descends, the push rod 21 is pulled into the push rod cavity 19, and then the blocking plate 26 slides down under the abutment of the fifth spring 25. When the connecting rod 12 is reset under the action of the second spring 13, the delay switch 35 senses the induction sheet 33. After a certain delay, the electric telescopic rod 10 starts to drive the lifting slide 4 to rise, and the above steps are repeated to complete the detection of the entire webbing. After the connecting rod 12 is reset, the air outlet pipe 6 against the upper surface of the webbing starts to blow air onto the webbing. If the webbing is of normal thickness, the air flow will be dispersed by the webbing and cannot be blown directly into the ventilation hole 8 to trigger the reminder mechanism. If the webbing has a gap or is thin, the air flow will blow directly into the ventilation hole to trigger the reminder mechanism. When the delay time ends and the lifting slide 4 rises, the air outlet pipe 6 is cut off.
