Abstract
Description
Technical Field
[0001] This utility model relates to a construction safety belt, and more particularly to a retractable and portable construction safety belt. Background Technology
[0002] According to the Work Safety Law, safety belts must be worn when working at heights of 2 meters or more above the fall height reference plane. Currently, the safety belts used on construction sites are manually retractable safety ropes, which are inconvenient to carry. Some workers often forget or do not want to carry their safety belts for convenience, making this inconvenience a major drawback. Therefore, it is necessary to provide a retractable and convenient construction safety belt. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a retractable and convenient construction safety belt that is not only easy to carry and use at any time, but also can automatically adjust the length of the safety rope, so that the range of high-altitude operations is not restricted, and can better protect the safety of high-altitude workers.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a retractable and convenient construction safety belt, including a safety rope. The safety rope is disposed inside a retractor. One side of the retractor includes a pivot, a locking component, a driving component, and a limiting disc. The other side of the retractor is a telescopic spring vortex. The limiting disc and the telescopic spring vortex are pivotally connected to the pivot, and the limiting disc is provided with a limiting groove. The safety rope is a high-strength polyester safety rope, which is wound around the pivot. One side of the retractor is attached to a safety belt hook, and the other side of the retractor is hung on a sturdy component. The locking component accelerates its rotation during accelerated descent and locks into the limiting groove as the limiting disc rotates. When there is no falling force, the limiting disc rotates in the opposite direction under the action of the telescopic spring vortex to automatically retract the safety rope.
[0005] Furthermore, the high-strength polyester safety rope is wound four times around the pivot, with a maximum freely retractable distance of 1.7m.
[0006] Furthermore, the sturdy component is a scaffold hook.
[0007] Compared with the prior art, this utility model has the following advantages: The retractable and convenient construction safety belt provided by this utility model combines the technology of freely retractable car seat belts with the high-strength polyester safety rope used for hoisting goods. The retractor is similar to the working principle of car seat belts, and the safety rope is a high-strength polyester belt used for hoisting goods. It is not only convenient to carry and use at any time, but also can automatically adjust the length of the safety rope, so that the high-altitude operation range is not restricted, and can better protect the safety of high-altitude workers.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Figure 1 This is a schematic diagram of the retractable and portable construction safety belt of this utility model. Figure 2 This is a schematic diagram of the retractable and portable construction safety belt structure of this utility model. Figure 3 This is a schematic diagram of the back fixing of the retractable and convenient construction safety belt of this utility model.
[0020] Please see Figure 1 , Figure 2 and Figure 3The present invention provides a retractable and convenient construction safety belt, including a safety rope, wherein the safety rope is disposed within a retractor 1. The retractor 1 includes a pivot 15, a locking component 12, a driving component 11, a limiting disc 13, and a telescopic spring coil 16. The limiting disc 13 is pivotally connected to the pivot 15 and is provided with a limiting groove 14. The safety rope is a high-strength polyester safety rope 2, which is wound around the pivot 15. One side of the retractor 1 is attached to the safety belt hook buckle 4 via the safety belt hook 5, and the other side of the retractor 1 is hung on a sturdy component; the limiting disc 13 accelerates its rotation during the accelerated descent, and as the limiting disc 13 rotates, the driving component 11 moves outward under the action of centripetal force, with its front end locked on the round teeth of the locking component 12 and its rear end locked in the limiting groove 14. When there is no gravity during the descent, the limiting disc 13 rotates in the opposite direction under the action of the telescopic spring vortex 16 to automatically retract the safety rope.
[0021] This utility model modifies the safety rope of the safety belt to be retractable, and attaches a safety rope retractor to the safety belt buckle; that is, one side of the retractor 1 is attached to the safety belt hook buckle 4 for easy carrying by workers, and the other side is hung on a sturdy component such as the scaffold hook 3, which is safe and convenient.
[0022] When a worker dons a safety harness, and an emergency occurs resulting in accelerated descent, the limiting disc 13 inside the retractor 1 will rotate rapidly. Under the action of centripetal force, the braking element 11 will rotate with the limiting disc 13, its front end engaging the circular gear of the locking element 12, and its rear end engaging the limiting groove 14. At this time, under the action of the locking element 12 and the limiting groove 14, the limiting disc 13 stops rotating, and the safety rope stops extending. When there is no gravity for descent, the telescopic spring vortex 16 inside the retractor 1 retracts, the pivot rotates in the opposite direction, and the extra extended safety rope rotates in the opposite direction, at which point the safety rope will automatically retract. Preferably, the high-strength polyester safety rope 2 is wound around the pivot 15 four times, with a maximum free extension and retraction distance of 1.7m.
[0023] This utility model, through the function of the retractor 1, can automatically adjust the length of the safety rope, providing workers with a certain degree of convenience when working at heights, and also gradually and passively cultivating workers' awareness of wearing safety belts at heights, thereby achieving the purpose of enhancing worker safety protection.
[0024] The retractor of this invention is similar to the working principle of a car seat belt, and the safety rope is a high-strength polyester strip used for hoisting goods. By combining the freely retractable technology of a car seat belt with the high-strength polyester safety rope used for hoisting goods, this invention creates a more convenient and retractable construction safety belt, which also overcomes the disadvantage of the heavy steel wire rope used in the previous speed difference safety rope.
[0025] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
