Description

Technical Field

[0001] The utility model relates to a locking buckle for internal fixation of a metal cable, belonging to the technical field of locking buckles. Background Art

[0002] According to the Chinese patent application number 202021786772.X, a locking buckle for a metal cable internal fixation system is disclosed, comprising a main body with two locking holes. The main body has six surfaces, one surface facing the bone, which is the bottom surface, and one surface facing away from the bottom surface, which is the top surface. The two surfaces respectively connect the long sides of the bottom surface and the top surface, which are the left side surface and the right side surface, and the two surfaces respectively connect the short sides of the bottom surface and the top surface, which are the front end surface and the rear end surface. The two locking holes extend from the front end surface to the rear end surface and are arranged from the left side to the right side. Two positioning claws are integrally formed at both ends of the length direction of the main body, and the two positioning claws located at the same end of the main body are respectively arranged on the left side and the right side. The claw tips of the four positioning claws are sharp and extend to the outside of the main body toward the bottom surface. The positioning claws at both ends of the main body are separated from each other.

[0003] However, during the actual use of the above solution, the entire device needs to be squeezed and deformed to achieve the locking effect. Regardless of whether the fixed position needs to be adjusted or the workers make mistakes during construction, the device cannot be disassembled and reinstalled, and the device cannot be readjusted for use. In view of the above shortcomings, the present invention proposes a locking buckle fixed inside the metal cable. Utility Model Content

[0007] A further improvement is that a fixed extrusion edge is provided in the middle of the left wall of the first cable opening, and a plurality of first anti-slip protrusions are provided at intervals on the right arc surface of the fixed extrusion edge. The first cable opening has the same structure as the second cable opening.

[0008] As a further improvement, a threaded opening for locking the bolt thread is provided on the top surface of the pressure groove, two anti-slip grooves are provided on the left and right groove walls at the upper end of the pressure groove, and a spring upper snap-on opening is provided in the middle of the bottom surface of the pressure groove.

[0009] A further improvement is that a plurality of second anti-slip teeth are arranged at intervals on the arc-shaped pressing concave surface.

[0010] A further improvement is that the first extrusion member includes an arc-shaped extrusion block, and a square sliding column that is compatible with the sliding mouth of the first extrusion member is laterally arranged on the right side of the arc-shaped extrusion block, and a first oblique cross-section is opened at the tail of the right end of the square sliding column, and a plurality of third anti-slip teeth are arranged at intervals on the arc-shaped surface on the left side of the arc-shaped extrusion block. The first extrusion member has the same structure as the second extrusion member.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides a locking buckle for fixing inside a metal cable. The locking buckle is composed of a buckle seat, a first extrusion piece, a second extrusion piece, a pressure piece, a spring, and a bolt structure. The locking buckle performs a locking operation on the two ends of the metal cable by synchronously tightening, clamping and biting, thereby preventing unilateral operation of the metal cable. The locking buckle is difficult to position, and anti-slip teeth are provided on the bottom surface of the buckle seat and the surface of the skeleton, so that the buckle seat will not slide during use and cause the metal cable to loosen. In addition, the locking buckle will not be deformed during use. The first extrusion piece and the second extrusion piece can be loosened to lock the metal cable by twisting the bolt upward. The position can be readjusted and reused, which is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
