Description

Technical Field

[0001] This utility model relates to a rope and strap connection structure, specifically a locking mechanism. Background Technology

[0002] In traditional rope and strap connection structures, tension is applied to the webbing during use. Under the action of tension, the front section of the webbing is pressed and fixed. Once the tension on the webbing is removed, the front section of the webbing is in a loose state. At this time, the front section of the webbing can easily slip out of the webbing hole. Utility Model Content

[0003] In view of the above problems, this utility model proposes a locking mechanism.

[0004] The technical solution of this utility model:

[0005] A locking mechanism includes a main body having at least one webbing connection structure. The main body is connected to a webbing via the webbing connection structure. The webbing connection structure consists of a webbing hole and a shaft. The shaft is disposed within the webbing hole and connected to the walls of the webbing hole at both ends. The front section of the webbing enters the webbing hole from one side (A) of the shaft and exits the webbing hole from the other side (B). The locking mechanism further includes a clamping structure mounted on the main body to clamp or release the front section of the webbing.

[0006] Further refining the above technical solution, the clamping structure is a sliding shaft with a hole on it. One side of the hole is narrow (narrow portion) and the other side is wide (wide portion). The front section of the webbing passes through the hole on the sliding shaft. The sliding shaft moves laterally and reciprocates between the clamping position and the releasing position. When the sliding shaft is in the clamping position, the front section of the webbing is located within the narrow portion of the hole on the sliding shaft. When the sliding shaft is in the releasing position, the front section of the webbing is located within the wide portion of the hole on the sliding shaft.

[0007] Further refining the above technical solution, the sliding shaft passes through the main body and is slidably connected to the main body. The two ends of the sliding shaft are pressing parts that are alternately exposed as the sliding shaft moves laterally.

[0008] To further refine the above technical solution, the holes on the sliding shaft and the webbing holes partially overlap on the B side of the shaft.

[0009] Further refining the above technical solution, the slide shaft is provided with an elastic clip, and the main body is provided with two slots or holes; the elastic clip moves laterally together with the slide shaft, and the two slots or holes are located on the movement path of the elastic clip; when the slide shaft is in the clamping position, the engaging part of the elastic clip is located in one slot or hole; when the slide shaft is in the loosening position, the engaging part of the elastic clip is located in the other slot or hole.

[0010] To further refine the above technical solution, the snap-fit ​​portion of the elastic clip has beveled sides on both sides, which are connected to the end face by an arc.

[0011] To further refine the above technical solution, the hole on the sliding shaft is an oblique hole.

[0012] Further refining the above technical solution, the sliding shaft and the elastic clip are integrated.

[0013] To further refine the above technical solution, the narrow and wide portions of the hole on the sliding shaft are transitioned by an inclined surface.

[0014] Further refining the above technical solution, the pressing part is toothed.

[0015] The advantages of this utility model are that it is reasonably designed and has a simple structure. The clamping structure is designed to clamp the front section of the webbing when there is no tension on the webbing, thereby fixing the front section of the webbing and preventing it from slipping out of the webbing hole.
