[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Alloy self-locking buckle, such as Figures 1 to 3 As shown, it includes a locking body 6 for installing ropes, and the locking body 6 has a rope-passing groove adapted to the rope. A pin is installed between the two sides of the locking body 6 by insertion, and a locking head 2 is sleeved on the outer wall of the pin. The locking head 2 has teeth integrally formed on its surface, and the same torsion spring 3 is fixed between the groove on the surface of the locking head 2 and the pin.

[0026] The end of the locking body 6 is a hook structure. The rope can pass through the rope groove inside the locking body 6, and the rope and the rope groove are on the same plane, so that the force direction of the rope and the force direction of the hook structure are completely consistent and on the same straight line, which can more perfectly realize the force of the rope. The locking head 2 and the torsion spring 3 can be installed using the pin. When the rope needs to be self-locked, the locking head 2 is first rotated along the pin. During this process, the torsion spring 3 is deformed. Then the rope enters from the bottom of the locking body 6, enters the rope groove, and finally passes out from the middle side of the locking body 6. After releasing the locking head 2, the locking head 2 presses the rope under the rebound force of the torsion spring 3, thereby fixing the rope. The teeth on the locking head 2 improve the fixing effect of the rope.

[0027] The pin component includes a pin screw 1 and a pin 4. The locking body 6 has a first insertion hole adapted to the pin 4 on one side, and the first insertion hole and the pin 4 are slidably connected. The locking buckle head 2 and the torsion spring 3 are both sleeved on the outer circumference of the pin 4. The locking body 6 has a second insertion hole on the other side, and the second insertion hole is equipped with a pin screw 1, and the pin screw 1 and the pin 4 are fixedly connected.

[0028] By setting pins and screws 1 and pins 4, the locking buckle 2 and torsion spring 3 can be limited between the inner walls on both sides of the locking body 6, so that the locking buckle 2 can use the rebound force of the torsion spring 3 to tighten the rope.

[0029] The rope component includes a main rope end 7 and a secondary rope end 8, which are integrally formed together. The secondary rope end 8 is used to insert into the rope groove, and the main rope end 7 is tightened by a locking buckle 2.

[0030] The locking body 6 is rotatably connected to a stop ring 5 at one end, and the stop ring 5 and the hook structure are used together.

[0031] Once the hook structure hooks onto the connecting facility such as a column, the stop ring 5 can prevent the hook structure from detaching.

[0032] Working principle: The rope consists of a main rope end 7 and a secondary rope end 8. In use, the secondary rope end 8 is first inserted into the rope-threading groove inside the locking body 6. The design of the rope-threading groove ensures that the rope and the inside of the locking body 6 are on the same plane, making the force direction of the rope completely consistent with the force direction of the hook structure of the locking body 6, thus optimizing the force distribution of the rope. Pins are installed between the two sides of the locking body 6 via an insertion method. When it is necessary to fix the rope, the user first tightens the locking buckle. 2. As the pin rotates, the torsion spring 3 deforms and stores energy. Then, the main rope end 7 of the rope is inserted from the bottom of the locking body 6, passes through the rope groove, and exits from the middle side of the locking body 6. Once the rope is correctly placed, the user releases the locking buckle 2. Under the rebound force of the torsion spring 3, the locking buckle 2 will quickly rotate and press against the main rope end 7 of the rope. The teeth integrally formed on the surface of the locking buckle 2 increase the friction on the rope, thereby achieving a firm fixation of the rope.

[0033] Example 2

[0034] Alloy self-locking buckles are used to improve the efficiency of threading ropes, such as... Figure 4 As shown, this embodiment makes the following additions based on embodiment 1: a connecting plate 11 is welded to the outer wall of one side of the locking body 6, and a threaded post 10 is threadedly connected to the surface of the connecting plate 11, and a threaded groove 9 that cooperates with the threaded post 10 is opened on the surface of the locking head 2.

[0035] To avoid prolonged hand manipulation of the locking buckle 2 during the rope threading process, the threaded groove 9 is rotated to its maximum angle. At this point, the threaded post 10 and the threaded groove 9 are aligned. The threaded post 10 is then threaded along the threaded groove 9. Once the threaded post 10 is inserted into the threaded groove 9, the threaded post 10 and the threaded groove 9 can limit the movement between the locking buckle 2 and the locking body 6. This ensures that the locking buckle 2 does not need to be manipulated by hand for an extended period during the rope threading process, making it easier to quickly thread the rope into the threading groove.

[0036] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
