DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and do not limit the utility model.

[0017] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0018] See also Figure 1 The utility model provides a flame retardant elastic band, the flame retardant elastic band comprising:

[0019] A first belt body 1 and a connecting sleeve 2, one end of the first belt body 1 is fixedly connected to the connecting sleeve 2, and the other end of the first belt body 1 is fixedly connected to a winding sleeve 3; a retracting mechanism 4 is installed on the winding sleeve 3, and a second belt body 5 is fixedly connected to the retracting mechanism 4, and the retracting mechanism 4 can be rotated to reel or release the second belt body 5, and the connecting sleeve 2 and the winding sleeve 3 are both provided with a through opening for the second belt body 5 to pass through; an extension mechanism 6, which is installed on the connecting sleeve 2, and is used to fix the second belt body 5 that passes through the through opening opened by the connecting sleeve 2 to extend the elastic band.

[0020] When using the flame-retardant elastic band, first, according to the required length of the elastic band, multiple second belt bodies 5 can be inserted into the adjacent connecting sleeves 2, and the control end of the extension mechanism 6 can be rotated so that the extension mechanism 6 can be inserted into the adjacent second belt bodies 5, thereby realizing the connection of multiple elastic bands. After the connection is completed, the elastic bands can be bundled. The bundled elastic bands are often loose. At this time, the control end of the retractable mechanism 4 can be rotated so that the retractable mechanism 4 can rewind the second belt bodies 5, thereby tightening the elastic bands.

[0021] like Figure 2 As shown, as a preferred embodiment of the utility model, the retracting mechanism 4 includes: a rotating column 41, both ends of which are rotatably connected to the inner wall of the winding sleeve 3, the rotating column 41 is fixedly connected to a turning handle 42 arranged outside the winding sleeve 3, a rotating drum 43 is fixedly arranged on the rotating column 41, the second belt body 5 and the rotating drum 43 are fixedly connected, and the rotating drum 43 can be rotated to reel or release the second belt body 5; a turntable 44, which is fixedly installed on the rotating column 41 and arranged on both sides of the rotating drum 43, and clamping openings are opened on the turntable 44 on both sides; a rotation limiting component 45, which is installed on the winding sleeve 3 and arranged on one side of the rotating drum 43, and the rotation limiting component 45 can enter the clamping opening opened by the turntable 44 to limit the rotation of the turntable 44 and the rotating column 41.

[0022] like Figure 3As shown, as a preferred embodiment of the utility model, the rotation limiting assembly 45 includes: a sleeve rod 451, one end of which is fixedly connected to the inner wall of the winding sleeve 3, and the other end of the sleeve rod 451 is sleeved with a sleeve 452, and a linkage rod 453 is fixedly connected between the sleeves 452 on both sides, and one side of the sleeve 452 is fixedly connected with a pull handle 454 extending to the outside of the winding sleeve 3; a clamping block 455, which is fixedly installed on the sleeve 452 and is arranged in coordination with the clamping port, and a push spring 456 for pushing the clamping block 455 into the clamping port is fixedly connected between the sleeve 452 and the inner wall of the winding sleeve 3.

[0023] In this embodiment, one side of the clamping block 455 is an inclined surface, so that the rotating disk 44 can overcome the forward rotation of the clamping block 455 but cannot rotate in the reverse direction.

[0024] When the second belt body 5 is to be wound up, the turning handle 42 is turned, and the turning handle 42 drives the rotating column 41 to rotate. The rotating column 41 can drive the turntable 44 to overcome the positive rotation of the clamping block 455. The rotation of the rotating column 41 can also drive the rotating drum 43 to rotate. The rotation of the rotating drum 43 can wind up the second belt body 5. When the second belt body 5 needs to be loosened, the pulling handle 454 is pulled to the left, and the pulling handle 454 can drive the sleeves 452, the linkage rod 453 and the clamping block 455 on both sides to slide along the sleeve rod 451 and compress the push spring 456, and the clamping block 455 can be disengaged from the clamping mouth. At this time, the rotation of the rotating drum 43 is no longer restricted, and the second belt body 5 can be loosened.

[0025] like Figure 4 As shown, as a preferred embodiment of the utility model, the extension mechanism 6 includes: a threaded barrel 61, which is rotatably installed in the connecting sleeve 2, the threaded barrel 61 is fixedly connected to a handle 62 arranged outside the connecting sleeve 2, the threaded barrel 61 is threadedly connected to a threaded column 63, and an insert plate 64 is fixedly arranged on the threaded column 63, and the insert plate 64 can be inserted into the second belt body 5 to fix the second belt body 5; a guide column 65, which is fixedly connected to the inner wall of the connecting sleeve 2 and distributed on both sides of the threaded barrel 61, and the guide columns 65 on both sides are provided with guide sleeves 66 fixedly connected to the insert plate 64.

[0026] When extending the elastic band, the second belt body 5 is inserted into the connecting sleeve 2, and the handle 62 is turned. The handle 62 drives the threaded tube 61 to rotate. The rotation of the threaded tube 61 can make the threaded column 63 drive the insertion plate 64 and the guide sleeve 66 to move downward along the guide column 65, and the insertion plate 64 can be inserted into the second belt body 5, thereby realizing the connection of multiple elastic bands.

[0027] like Figure 1 As shown, as a preferred embodiment of the utility model, the first belt body 1 and the second belt body 5 are both composed of a combination of flame-retardant yarn and spandex yarn, and the flame-retardant yarn is wrapped outside the spandex yarn.

[0028] At present, latex yarn wrapped polyester yarn is mainly used to make elastic bands. Because the latex yarn is thick and the yarn is thin, the flame retardant effect is not ideal. Now spandex yarn is used instead. The flame retardant yarn is wrapped with spandex thin yarn, and the flame retardant effect is very good. Firefighting, disaster relief, military uniforms and airplanes and high-speed trains must now use flame retardant elastic bands. This band will not catch fire and is widely used. It was developed by our factory and has been put on the market in large quantities.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
