[0048] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0049] Reference Figure 1-Figure 5 The connector includes: a clamping ring 11, a locking piece, a first fixing ring 12, and a second fixing ring 13.

[0050] The clamp ring 11 is provided with a plurality of continuous guide arc surfaces 14 , which prevent the safety belt from sliding easily when it is locked.

[0051] The first fixing ring 12 is fixedly connected to one end of the snap ring 11, and the second fixing ring 13 is fixedly connected to the other end of the snap ring 11. The first fixing ring 12 and the second fixing ring 13 have the same structure and are symmetrically arranged on both ends of the snap ring 11. A first clamping groove 25 is arranged on the inner wall of the first fixing ring 12, and a second clamping groove 24 is arranged on the inner wall of the second fixing ring 13. The second clamping groove 24 and the first clamping groove 25 are both annular clamping grooves, and the aperture of the second clamping groove 24 is the same as the aperture of the first clamping groove 25.

[0052] The locking member includes: a lock cylinder 15, a slide bar 21, and a stop ball 23. The lock cylinder 15 is inserted into the first fixing ring 12 and the second fixing ring 13 in sequence and the lock cylinder 15 is slidably connected to the first fixing ring 12 and the second fixing ring 13 respectively. A slide groove is provided in the lock cylinder 15, which passes through both ends of the lock cylinder 15, and a plurality of through holes 26 are provided on the side wall of the slide groove at equal intervals. One end of the slide bar 21 is slidably connected to the slide groove, and two grooves 22 are provided on the outer wall of the slide bar 21, and the grooves 22 are annular grooves. A plurality of stop balls 23 are provided and are respectively rollingly connected to each through hole 26.

[0053] In order to enable the slide rod 21 to be reset, a spring pressing member is further provided. The spring pressing member includes: a button cap 16 , a button 17 , a pressure plate 20 , and a reset spring 19 .

[0054] The button cap 16 is fixedly connected to one end of the lock cylinder 15, and a reset groove 18 is provided in the button cap 16. One end of the slide bar 21 extends into the reset groove 18 and passes through the button cap 16. The button 17 is slidably connected to the button cap 16 and fixedly connected to the slide bar 21. The button 17 passes through the button cap 16 and a part of the button 17 extends into the reset groove 18. One end of the slide bar 21 extending into the reset groove 18 is fixedly connected to the button 17, and the pressure plate 20 is fixedly connected to the button 17. The reset spring 19 is sleeved on one end of the slide bar 21 extending into the reset groove 18, and the two ends of the reset spring 19 are respectively in direct or indirect pressing contact with the pressure plate 20 and the end wall of the lock cylinder 15.

[0055] The ball diameter of the limiting ball 23 is D2, the aperture of the through hole 26 is D3, D2 is less than or equal to D3. The distance between the inner groove wall of the groove 22 and the outer wall of the lock cylinder 15 is D1, D1 is greater than or equal to D2.

[0056] Working or installation process:

[0057] Initial state: one end of the lock cylinder 15 is inserted into the first fixing ring 12, and a part of the limiting ball 23 extends out of the through hole 26, and the limiting ball 23 extending out of the through hole 26 is engaged in the first card groove 25, and the outer surface of the slide bar 21 is pressed and contacted with the limiting ball 23. At this time, the limiting ball 23 and the groove 22 are staggered (such as Figure 2 shown);

[0058] When the connector needs to be unlocked, the button 17 is pressed and held, and the button 17 drives the pressure plate 20 and drives the pressure plate 20 to move. The pressure plate 20 squeezes the return spring 19, and the button 17 pushes the slide bar 21 and makes the slide bar 21 move to the side close to the limiting ball 23. At this time, when the groove 22 moves to the same horizontal plane as the through hole 26, the limiting ball 23 rolls into the groove 22, and the limiting ball 23 moves to the side away from the first fixing ring 12. The limiting ball 23 completely enters the through hole 26, and the spherical surface of the limiting ball 23 contacts the inner groove wall of the groove 22. The groove wall of the first slot 25 no longer limits the limiting ball 23, and at this time, the button 17 is still pressed and the button cap 16 is pulled, so that the button cap 16 moves to the side away from the first fixing ring 12, and the button cap 16 drives the lock cylinder 15 to be pulled out of the first fixing ring 12 until a part of the through hole 26 is provided on the lock cylinder 15 The locking nut 24 is pressed against the locking ball 23, thereby causing the second locking ring 13 to limit the locking cylinder 15 and preventing the locking cylinder 15 from sliding.

[0059] When the connector needs to be locked again, the button 17 is kept pressed, and the button 17 pushes the slide bar 21, and the slide bar 21 drives the groove 22 to move to communicate with the second slot 24, and the slide bar 21 magnetically absorbs the limiting ball 23, and causes the limiting ball 23 to move to the side close to the slide bar 21, and causes the limiting ball 23 to move into the groove 22 and be absorbed in the groove 22 by the slide bar 21, at this time, the limiting ball 23 is no longer pressed and contacted with the second slot 24, and the button cap 16 is pushed, and the button cap 16 drives the lock cylinder 15 and the slide bar 21 to move into the first fixing ring 12, and the button cap 16 is close to the second fixing ring. The end wall of the ring 13 is pressed and contacted with the end wall of the second fixed ring 13. At this time, the limiting ball 23 moves to the position of the first slot 25. The button 17 is released, and the return spring 19 pops open the pressure plate 20 and the button 17 and makes the groove 22 move to the side close to the second fixed ring 13. The groove wall of the groove 22 presses and pushes the limiting ball 23, and a part of the limiting ball 23 passes through the through hole 26 until it extends into the first slot 25, so that the groove wall of the first slot 25 limits the limiting ball 23, and the groove wall of the slide rod 21 limits the limiting ball 23. At this time, the lock cylinder 15 is locked.
