Description

Diving knife automatic locking structure

technical field

The utility model relates to a diving knife, in particular to a diving knife with an automatic locking device at the junction of a scabbard and a knife handle.

Background technique

Existing diving knife is made up of knife body, knife handle, scabbard etc., can carry out cutting operation and use after diving; The tight fit with the sheath groove is poor, and the knife body is easy to fall out of the sheath. Usually, a locking device is added at the end of the handle, and a fixed buckle is added to clamp the knife body in the sheath. These additional components not only increase the manufacturing cost, but also destroy the overall aesthetic feeling of the diving knife, so it is necessary to improve it.

Contents of the invention

Aiming at the defects existing in the prior art, the technical problem to be solved by this utility model is to provide a diving knife automatic locking structure with simple and compact structure, good reliability, stable and fast knife extraction, practical and effective, so that the knife body can be smoothly loaded into the The knife handle is automatically locked behind the scabbard groove. The utility model designs the shape of the knife handle of the diving knife to conform to the contour curve held by a human hand, so that the outer contour curve of the knife handle of the diving knife has a streamlined aesthetic feeling in appearance.

In order to achieve the above-mentioned purpose, the automatic locking structure of the diving knife of the present utility model adopts the following technical solutions:

An automatic locking structure for a diving knife, including a scabbard, a knife body, and a knife handle. Tail, the concave tail end is provided with buckle shrapnel.

Further, a buckle groove is respectively provided on both sides of the notch end of the scabbard, and the convex head of the buckle groove points to the inside of the notch of the scabbard;

Further, a concave tail is provided on both sides near the end of the knife body of the handle, and the convex groove of the concave tail is close to the knife body;

The two sides near the concave tail end of the above-mentioned knife handle are respectively provided with a buckle shrapnel, and the ends of the buckle shrapnel collide with the convex groove of the concave tail.

The knife body and the knife handle of the utility model are designed to form a smooth curve, and the grip part of the knife handle is designed in a bow arc shape. When in use, the thumb and forefinger of the person hold the root of the knife handle tightly to press and buckle the shrapnel, so that the buckle groove of the scabbard is released. , so that the knife body can be pulled out of the scabbard slot safely and quickly, and the use is safe and reliable.

Detailed ways

In order to further understand the features, technical means, and specific objectives and functions of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The relevant structure of the utility model mainly includes the following parts (or devices): scabbard 1, knife body 2, buckle groove 3, buckle shrapnel 4, knife handle 5, concave tail 6.

The knife body 2 of the diving knife is inserted into the notch of the scabbard 1, the knife body 2 is fixed on the end of the handle 5, the notch end of the scabbard 1 is provided with a buckle groove 3, and the end of the scabbard 5 near the scabbard body 2 is provided with a concave Tail 6, the end of concave tail 6 is provided with buckle shrapnel 4.

Both sides of the notch end of the scabbard 1 are respectively provided with a buckle groove 3, and the convex head of the buckle groove 3 points to the inside of the notch of the scabbard 1 (see accompanying drawing 3); The concave tail 6 and the convex groove of the concave tail 6 are close to the knife body 2; the two sides of the knife handle 5 near the concave tail 6 are respectively provided with a buckle shrapnel 4, and the ends of the buckle shrapnel 4 collide with the convex groove of the concave tail 6 (see accompanying drawing 2).

The utility model is provided with a simple, practical and safe scabbard 1 and a knife handle 5. The knife body 2 is inserted into and pulled out of the scabbard 1 quickly and reliably. After the scabbard 1 and the handle 5 are combined, when you want to pull it out for use, press inward on both sides of the end of the buckle shrapnel 4, and use the principle of leverage to open the buckle groove 3 of the scabbard 1 easily and safely. Quickly pull out the cutter body 2 for use. When the scabbard 1 and the handle 5 are to be combined, as long as the scabbard 2 is inserted according to the notch of the scabbard 1, it is safe and reliable; because the scabbard 1 and the buckle groove 3 of the scabbard 1 are made of tough plastic One-piece molding, good elasticity and strength, can meet safety requirements.

The above-mentioned embodiments are only used to illustrate the utility model for convenience, and are not intended to limit the utility model in any form. Anyone with ordinary knowledge in the technical field, if within the scope of the technical characteristics of the utility model , Equivalent embodiments made with partial changes or modifications using the technical content disclosed in the utility model, and without departing from the technical features of the utility model, all still fall within the scope of the utility model's technical features.
