Detailed ways
As shown in the figure, the retractor for easy unwinding and pulling out disclosed by the present utility model includes an installation frame 9, and the installation frame 9 is rotatably provided with a tape winding shaft 5, and both sides of the tape winding shaft 5 are connected with ratchets 6. A swinging member 8 is movably arranged on the mounting frame 9. The swinging member 8 is provided with a raised portion 7 that can cooperate with the ratchet 6 to be pressed tightly. A spring 17, the mounting frame 9 is hinged with a positioning clamping arm 12 below the lever 15, the positioning clamping arm 12 is provided with a slot 11 that cooperates with the lever 15, and the positioning clamping arm 12 is connected with the second spring 13 , so that the positioning clamping arm 12 abuts on the lever 15 , a push rod 14 is slidably arranged on the mounting frame 9 , and the push rod 14 can push the positioning clamping arm 12 to swing. Further, the mounting bracket 9 is arranged in the outer casing 25, the outer casing 25 has a flip 1, the flip 1 has a cylindrical plug 3, and the outer casing 25 is provided with a socket 10 for the cylindrical plug 3 to be inserted, ensuring that the flip 1 is inserted. For the stability of insertion after closing, the flip cover 1 is provided with a bar-shaped groove 2 through which the lever 15 passes. In addition, it also includes a pressing head 16, one end of the lever 15 is extended with a clamping head 24, an annular clamping groove 25 is opened at the clamping head 24, and a cavity 18 is opened at the bottom of the pressing head 16, and the cavity 18 A cylindrical connecting portion 22 is provided, the side wall of the pressing head 16 is provided with a through hole 23 passing through the cylindrical connecting portion 22, and the inner side wall of the cylindrical connecting portion 22 has a clamping block 20 that can be inserted into the annular groove 25. The side walls of the shaped connecting portion 22 are provided with disconnecting grooves 21 on both sides of the clamping block 20, and a baffle plate 19 that can be abutted against the clamping head 24 is arranged in the cavity 18. By setting the pressing head 16, it is more convenient for the user to press the dial Move the lever 15, when assembling the pressing head 16, the through hole 23 on the pressing head 16 can be aligned with the lever 15 and plugged together, the clamping head 24 of the clamping head 24 will first contact and squeeze the clamping block 20, so that the clamping The mounting block 20 can be snapped into the annular snap groove 25, and the snap-on head 24 is just held up by the baffle plate 19 at this time, thereby realizing the positioning and inserting of the pressing head 16 and the lever.
The retractor of the present invention drives the lever 15 to swing downward by pressing the pressing head 16, and then drives the swinging member 8 to swing away from the ratchet 6, so that the belt winding shaft can rotate smoothly to unwind the safety belt. Pull out, and when the lever 15 swings down to the slot 11 on the positioning arm 12, the positioning arm 12 will swing under the action of the second spring 13 and make the slot 11 clamp the lever to realize the For the positioning of the lower swing of the lever 15, when the seat belt is pulled out, the push rod 14 is squeezed to push the positioning arm 12 to swing back. At this time, the lever 15 is no longer positioned by the slot 11, and the first spring 17 It resets under the action of the pulley, and drives the swinging member 8 to swing back, and the ratchet wheel 6 is clamped again to limit the rotation of the winding shaft 5, so as to realize the locking of the retractor.
The utility model is simple in structure and reasonable in design, and can realize large-scale production; by setting the lever positioning device, when the lever is pressed down to drive the swing piece to separate from the ratchet, the lever can be positioned, so that the lever does not need to be pressed all the time. , it is more convenient to unwind and pull out the seat belt.
