[0004] When the above equipment is used, the clamping member and the pressing handle are used to lock the safety rope in the elliptical cylinder body. The locking method is relatively single. If the locking effect decreases due to wear during the use of the seat belt or the operation is not standardized, resulting in a sudden situation where there is no stable locking, it is easy to directly cause an accident. The error tolerance rate during the use of the buckle is low, and it cannot cope with sudden situations. At the same time, the application range of the buckle is low, and it can only be used on the safety rope to lock the safety rope, and cannot be applied to the locking of other seat belts according to the use situation.

The engagement between the clamping member 2 and the safety rope can be made more stable through the tooth groove 11, making the installation of the connecting plate 5 more stable.

[0026] The threaded rod 3 includes a square rod 301, a top plate 302, a restricting member 303, and a magnet 304. The other end of the threaded rod 3 is provided with the square rod 301. The top of the square rod 301 is provided with the top plate 302. The restricting member 303 is arranged on the square rod 301, and magnets 304 are arranged on both sides of the restricting member 303.

[0027] The top plate 302 can prevent the restricting member 303 from detaching from the square rod 301.

[0028] In this embodiment, there are three groups of clamping members 2 in total. The clamping members 2 are adapted to the main body 1, and the threaded rod 3 passes through the threaded hole 10 and has a threaded connection with the threaded hole 10.

[0029] Specifically, the clamping member 2 can cooperate with the main body 1 to achieve the effect of clamping the safety rope, and can be used to clamp the connecting plate 5 when the buckle is used for the safety belt.

[0030] In this embodiment, the operating end 4 is fixedly installed at one end of the threaded rod 3. The width of the notch 12 is adapted to the diameter of the threaded rod 3, and the tooth 13 is adapted to the tooth groove 11.

[0031] Specifically, the operating end 4 facilitates the rotation of the threaded rod 3.

[0032] In this embodiment, the bearing 9 is fixedly embedded in the round hole 8, and the other end of the threaded rod 3 passes through and is fixed in the inner ring of the bearing 9.

[0033] Specifically, the round hole 8 facilitates the installation of the bearing 9.

[0034] In this embodiment, after the threaded rod 3 passes through the bearing 9, it is fixedly connected to the square rod 301. The square groove 7 is adapted to the restricting member 303, and the restricting member 303 is sleeved on the square rod 301.

[0035] Specifically, the square groove 7 can provide an installation environment for the restricting member 303.

[0036] In this embodiment, the top plate 302 is fixedly installed at the outer end of the square rod 301, and the top plate 302 is specifically made of magnetic metal.

[0037] Specifically, the square rod 301 can cooperate with the square groove 7 and the restricting member 303 to achieve the effect of restricting the rotation of the threaded rod 3.

[0038] In this embodiment, the magnets 304 are fixedly embedded on both sides of the restricting member 303. The three groups of clamping members 2 correspond to the three groups of threaded rods 3 and have the same installation structure.

[0039] Specifically, the magnet 304 can ensure the stability of the limiting member 303 in the square groove 7 .

[0040] Working principle and use process of the utility model: In actual use, if it is applied to the safety rope for locking, one end of the safety rope can be passed through the main body 1 from top to bottom, and the safety rope is bypassed in an S shape when passing through the three sets of threaded rods 3;

[0041] When the safety rope needs to be locked, first remove the connecting plate 5, then move the limiting piece 303 to be adsorbed on the top plate 302 through the magnet 304 on one side, then rotate the threaded rod 3 through the operating end 4, the threaded rod 3 rotates flexibly under the action of the bearing 9, the square rod 301 rotates in the square groove 7, and the clamping piece 2 threadedly connected with the threaded rod 3 will gradually approach the inside of the main body 1, and finally clamp the safety rope in the main body 1, and then move the limiting piece 303 to one side so that the limiting piece 303 enters the square groove 7 and generates magnetic adsorption with the bearing 9, and the square rod 301 rotates in the square groove 7. The rod 301 can restrict the threaded rod 3 to prevent it from rotating, so that the position of the clamping member 2 is fixed. Under the action of the tooth groove 11, the connection between the clamping member 2 and the safety rope can be more stable, and the anti-slip effect is better. If the safety rope slips due to improper locking operation or serious wear during use, since the installation structures and operating structures of the three groups of clamping members 2 are independent of each other, when the clamping effect of one group of clamping members 2 is reduced, the other two groups can continue to keep the locking of the safety rope stable, thereby improving the fault tolerance rate during use;

[0042] Insert the lower end of the connecting plate 5 between the main body 1 and the clamping member 2, and make the teeth 13 correspond to the tooth grooves 11, and rotate the threaded rod 3 in the same way as above so that the clamping member 2 clamps the connecting plate 5 between the main body 1 and the clamping member 2. At this time, the teeth 13 fit with the tooth grooves 11, and the connecting plate 5 is fixed. The ends of one set of safety belts are fixed in the connecting port 6. In this way, the ends of another set of safety belts can be connected to another set of connecting plates 5, so as to achieve the effect of connecting the safety belts. Whether to use the connecting plate 5 can be selected according to actual conditions. It can be suitable for locking the safety rope and locking the safety belt, thereby improving applicability.
