[0021] Specific embodiment 1: Please refer to Figure 1-Figure 5 A quick elastic webbing buckle, the utility model provides a quick elastic webbing buckle, comprising a buckle seat 1, a cover 2 and a roller device.

[0022] The cover 2 is arranged on the buckle seat 1 through rivets 13, and the cover 2 and the two sides of the socket seat respectively form a left and right through accommodating cavity. After the buckle seat 1 and the cover 2 are buckled together, there are two upper and lower grooves, and the roller device is arranged in the upper groove.

[0023] The roller device includes an upper roller 3 and a lower roller, which are symmetrically arranged and detachably connected by screws. The roller device is arranged in a symmetrical split structure, which can provide convenience during installation and removal, and is also conducive to the installation and removal of subsequent parts.

[0024] Two ends of the roller device are respectively located in corresponding accommodating cavities.

[0025] Both end surfaces of the roller device are provided with a clamping groove 15 and a rotating groove 16 in sequence from outside to inside along the axial direction. The diameter of the clamping groove 15 is smaller than that of the rotating groove 16.

[0026] The accommodating chamber is provided with a switch device. A connector 14 is provided at one end of the switch device close to the roller device, and the connector 14 matches with the clamping groove 15 to form a plug-in connection with rotation in the fixed mode.

[0027] The diameter of the end of the switch device is smaller than the clamping groove 15, and the size of the joint 14 is smaller than the rotating groove 16, so as to form a movable self-rotating connection in the adjustment mode. The switch device directly or indirectly abuts against the inner wall of the accommodating cavity to limit the self-rotation.

[0028] The switch device includes a stop block 9 and a connecting rod 5; the connecting rod 5 is inserted into the stop block 9 to enable the connecting rod 5 to move toward and away from the roller device; the front and rear end faces of the stop block 9 are respectively abutted against the front and rear side faces of the accommodating cavity to achieve the stop of the switch device.

[0029] A spring 7 is arranged in the rotation groove 16; the spring 7 abuts against the side wall of the rotation groove 16 and the end of the joint 14. Spring 7 seats are arranged at both ends of the spring 7. The spring 7 seats can support the spring 7 and ensure that the spring 7 can be correctly placed in the predetermined position.

[0030] The receiving chamber formed by the buckle seat 1 and the cover 2 is provided with a sliding groove; a slider is slidably connected to the sliding groove; and the slider is fixedly connected to the switch device. The sliding groove and the slider can help the roller device to move in the up and down directions, and assist the use of the roller device.

[0031] The outer circumferential surface of the connecting rod 5 inserted into the stop block 9 is provided with a limiting groove; the stop block 9 is penetrated by a locking screw 1, and the locking screw 1 is located in the limiting groove to limit the movement range of the connecting rod 5.

[0032] A switch housing 11 is provided at the end of the switch device away from the roller device, and the outer end surface area of ​​the switch housing 11 is larger than the end surface area of ​​the switch device. A plurality of concave and convex stripes are provided on the switch housing 11. The concave and convex stripes provided on the switch housing 11 can increase the friction with the surface of the switch housing 11, and it is not easy to slip when pressed. The switch device and the switch housing 11 can be integrated, or they can be detachable by a set screw 2.

[0033] The joint 14 of the connecting rod 5 can adopt a spline structure or a hexagonal structure. The dimensions of the roller device and the front end clamping part of the connecting rod 5 match. The spline structure or the hexagonal structure is used to lock and release the roller device.

[0034] Working principle: When the roller device is in the fixed mode, the switch device is in a stationary state, the connector 14 is clamped in the clamping groove 15, and the roller device is stationary and does not rotate; in the adjustment mode, when the switch device is pressed in the direction of the roller device at the same time, the connector 14 is separated from the clamping groove 15 and enters the rotation groove 16, the roller device is released, and the roller device can rotate freely to achieve the rapid release of the webbing. The setting of the sliding groove and the slider helps the roller device to move up and down for adjustment, and the spring 7 helps the switch device to clamp and reset.

[0035] Specific embodiment 2: The difference from specific embodiment 1 is that the roller device is integrally formed.
