Abstract
Description
Technical Field
[0001] The utility model relates to the field of performance sword products, and more specifically to a torsion-proof reinforcement structure for a blade and a hand guard of a professional training competition sword. Background Art
[0002] Performance knives are widely used in performances, competitions, and exercises. Existing performance knives are composed of a blade, a knife ring, and a knife handle. The knife ring is provided with a connecting hole, and the blade is composed of a blade, a connecting button, and a connecting rod. The knife handle is provided with a mounting hole. During installation, the connecting rod is inserted into the connecting hole, and then inserted into the mounting hole until it passes through the mounting hole. At this time, the connecting button passes through the connecting hole, and then a screw is screwed on the connecting rod passing through the connecting hole to fix it, thus completing the installation of the knife. Since the thickness of the connecting button is smaller than the diameter of the connecting rod, and the width of the connecting hole is larger than the thickness of the connecting button, the blade is fixed by tightening the screw and then contacting the handle. During performances, competitions, and exercises, the torsion of the blade will be transmitted to the connecting rod, causing the connecting rod and the screw to loosen, resulting in excessive left-right torsion of the blade, which is not conducive to performances, competitions, and exercises.

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0018] Reference Figure 1 one Figure 5 As shown, a blade and hand guard anti-twist reinforcement structure of a professional training competition knife in this embodiment includes a blade 1, a knife ring 2 and a handle 3, the blade 1 includes a blade portion 11, a connecting button 12 and a connecting rod 13, the knife ring 2 is provided with a connecting hole 21, the knife handle 3 is provided with a mounting hole 31, the knife ring 2 is provided with a locking groove 22, the locking groove 22 is located on both sides of the connecting hole 21 and is connected to the connecting hole 21, the width of the locking groove 22 is greater than the width of the connecting button 12, both sides of the connecting button 12 are located in the locking groove 22, the knife handle 3 is provided with a locking block 32 at the end of the mounting hole 31, a locking gap 321 is formed between adjacent locking blocks 32, the position of the locking gap 321 matches the locking groove 22, and the connecting button 12 is embedded in the locking gap 321.
[0019] Through the above technical solution, after the blade 1, the blade ring 2 and the handle 3 are connected, the two ends of the connecting button 12 are embedded in the locking groove 22; the part that penetrates into the handle 3 is located in the locking gap 321, and the two sides of the connecting button 12 are in conflict with the locking block 32, which reduces the torsion amplitude of the blade 1 during practice without affecting the production and installation efficiency.
[0020] As an improved specific implementation, the connection between the connection hole 21 and the locking groove 22 is arranged in an arc shape.
[0021] Through the above technical solution, the connection between the connecting hole 21 and the locking groove 22 is arranged in an arc shape, the opening is gentle, and processing is convenient.
[0022] As an improved specific implementation, the knife ring 2 is provided with a locking protrusion 23 on the edge of the locking groove 22, and the locking protrusion 23 is located on the side of the knife ring 2 facing the knife handle 3. The locking block 32 is provided with a fastening groove 322, and the position of the fastening groove 322 corresponds to the position of the locking protrusion 23.
[0023] Through the above technical solution, after the blade 1, the blade ring 2 and the handle 3 are connected, the connecting button 12 abuts against the locking protrusion 23, and the locking protrusion 23 abuts against the fastening groove 322, further improving the structural strength after installation and thereby reducing the torsion amplitude of the blade 1.
[0024] As an improved specific implementation, the locking protrusion 23 and the knife ring 2 are formed in one piece.
