Description

Spacing formula climbing knot Technical Field The utility model relates to the technical field of rope buckles, in particular to a limiting type climbing buckle. Background In outdoor activities such as mountain climbing and rock climbing, the fixing and connection of the cables are important links for ensuring safety, and the connection or binding of the cables is usually realized by means of a lock catch. The reliability of the latch is directly related to the safety of the user, especially in a high risk environment, if the latch opening breaks loose or loosens accidentally, the cable may be pulled loose, so that serious danger is caused. There is a safety knot with locking structure among the prior art, and it is through the cooperation of internal thread circle and safety knot main part to combine L shape piece to carry out spacingly to the internal thread circle, prevent that the internal thread circle from rocking in the use, thereby improve the stability of hasp. However, such safety buckles have significant drawbacks in practical use, mainly in terms of inconvenient operation. The opening and closing process of the cable rope is operated cooperatively by two hands, the cable rope can be loaded into or unloaded from the cable rope after the cable rope is stabilized, and the requirement of one-hand rapid operation cannot be met, so that the cable rope is particularly disadvantageous in emergency situations or scenes in which the cable rope is required to be frequently taken and put. In addition, in some specific climbing links, a climber needs to frequently take out or put in the rope from the buckle, and in this case, a higher requirement is placed on the convenience of the operation of the buckle. However, conventional shackle designs often have difficulty balancing fast operation with safety. On one hand, the frequent rope taking and putting scene needs to reduce the interference of the limiting structure to improve the efficiency, and on the other hand, the climbing buckle used as a safety guarantee tool also needs to have a reliable limiting function to prevent unexpected loosening. How to design a climbing buckle which can meet the requirement of frequent taking and placing of ropes and ensure the limiting reliability becomes a technical problem to be solved urgently. Therefore, the development of the climbing buckle which can be operated rapidly by one hand, has an automatic reset function and can flexibly switch the limit state according to the use scene has important significance. Disclosure of utility model The utility model aims to provide a limiting type climbing buckle which overcomes the defects in the prior art. In order to achieve the above object, the present utility model provides the following technical solutions: A limit type climbing buckle comprises a buckle body, a movable pin, a stress spring piece, a torsion spring and a limit piece. The buckle body is of a U-shaped structure and is made of high-strength and toughness materials and used for bearing external tensile force, and a notch is formed in one side of the buckle body for installing the movable pin. And two ends of the notch are respectively matched with the movable pin and the stress elastic sheet, so that the stability of the whole structure is ensured. Further, one end of the movable pin is rotationally connected with the buckle body, and the other end of the movable pin is provided with a buckling groove for being matched with the buckle body to realize a closing function. The movable pin is internally provided with a stress spring plate in an embedded mode, one end of the stress spring plate is fixed at the notch of the buckle body, and the other end of the stress spring plate applies strain pressure to the movable pin, so that the movable pin is always kept in a state of being abutted to the buckle body, and free opening and closing of the movable pin in an unlocked state are ensured. In particular, the stress spring is embedded into the movable pin and fixedly connected with the buckle body, and is used for providing continuous elastic pressure for the movable pin. The design of the stress spring sheet ensures that the movable pin is always tightly attached to the buckle body in an unlocked state, and accidental loosening caused by external force is avoided. Further, the torsion spring is sleeved on the movable pin, and two ends of the torsion spring extend out of the limit strips respectively. One of the limiting strips is inserted into the preset hole of the movable pin, and the other limiting strip is fixedly inserted into the limiting piece. The elastic action of the torsion spring enables the limiting piece to reset and rotate, and reset and move in the axial direction, so that the automatic reset function of the limiting piece is realized. Further, the limiting piece is sleeved on the movable pin, the top is provided with a pair of through grooves and an inwards concave buckling opening, and the bottom is c
