Abstract

The utility model relates to a diving knife automatic locking structure. The utility model provides the diving knife automatic locking structure which has the advantages of simple and compact structure, good reliability, stable and fast drawing of knife, practicability and effectivity, which can automatically lock a knife handle after a knife body is smoothly arranged in a scabbard slot. The utility model comprises a scabbard, the knife body and the knife handle, wherein the knife body is fixedly arranged at the end part of the knife handle; the slot end of the scabbard is provided with a buckling slot, and the end of the knife handle, which is near to the knife body, is provided with a concave tail, and the end part of the concave tail is provided with a pressing and buckling elastic plate. The knife body and the knife handle of the utility model are designed into an integrated smooth curve; the hand gripping part of the knife handle is designed into an arch; when in use, the thumb and the index finger of the user grip the pressing and buckling elastic plate which is arranged at the root part of the knife handle, so the buckling slot of the scabbard is released, and the knife body can be pulled out of the scabbard slot safely and rapidly, therefore the usage is safe and firm.

Description

Diver automatically locks structure

Technical field

The utility model relates to a kind of diving cutter, relates in particular to the diver that a kind of sheath and cutter handle combining part have automatic locking apparatus.

Background technology

Existing Diving knife is made up of cutter hub, handle of a knife, sheath etc., can cut to cut and manipulate behind diving; The cutter hub of diver tightly inserts in the sheath, and handle of a knife is exposed to outside the sheath, because the tight fit intensity difference of cutter hub handle and sheath groove makes cutter hub drop out outside the sheath easily, adds lock uint at the handle of a knife tail end usually, adds clip cutter hub is clamped in the sheath.These extra assemblies that increase, not only manufacturing cost increases, and destroys the overall aesthetic of diver, so in addition improved necessity is arranged.

Summary of the invention

At the existing in prior technology defective, technical problem to be solved in the utility model provides a kind of simple and compact for structure, good reliability, take out that cutter is stable fast, the practical and effective diver automatically locks structure, cutter hub is packed into smoothly automatically lock handle of a knife behind the sheath groove, the utility model becomes to meet the contour curve that staff grips with the shaped design of the handle of a knife of diver, makes the peripheral contour curve of handle of a knife of diver have the streamline aesthetic feeling in appearance.

For reaching above-mentioned purpose, diver of the present utility model automatically locks structure, adopts following technical scheme:

A kind of diver automatically locks structure, includes sheath, cutter hub, handle of a knife, and cutter hub is fixedly arranged on the handle of a knife end, and sheath notch end is provided with catching groove, and the nearly cutter hub end of handle of a knife is provided with the spill tail, and the spill tail end is provided with the clinching shell fragment.

Further, described sheath notch end both sides respectively are provided with a catching groove, and catching groove convex head points to sheath notch inboard;

Further, the nearly cutter hub end both sides of described handle of a knife respectively are provided with a spill tail, and the tongue of spill tail is near cutter hub;

The nearly spill tail end both sides of above-mentioned handle of a knife respectively are provided with a clinching shell fragment, the tongue of clinching shell fragment end conflict spill tail.

Cutter hub of the present utility model and handle of a knife are designed to the smooth curve of one, handle of a knife is held partly bow shape design, and people's thumb and the forefinger handle of a knife root clinching shell fragment of holding with a firm grip unclamps the catching groove of sheath during use, allow cutter hub safety extract the sheath groove again fast, safe in utilization firm.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the schematic diagram of the utility model embodiment cutter hub part;

Fig. 3 is the schematic diagram of the utility model embodiment sheath part;

Fig. 4 is the generalized section of the utility model embodiment.

The specific embodiment

For further understanding feature of the present utility model, technological means and the specific purposes that reached, function, the utility model is described in further detail below in conjunction with the accompanying drawing and the specific embodiment.

The utility model dependency structure mainly comprises following parts (or device): sheath 1, cutter hub 2, catching groove 3, clinching shell fragment 4, handle of a knife 5, spill tail 6.

The cutter hub 2 of diver inserts in sheath 1 notch, and cutter hub 2 is fixedly arranged on handle of a knife 5 ends, and sheath 1 notch end is provided with catching groove 3, and nearly cutter hub 2 ends of handle of a knife 5 are provided with spill tail 6, and spill tail 6 ends are provided with clinching shell fragment 4.

Sheath 1 notch end both sides respectively are provided with a catching groove 3, and catching groove 3 convex heads point to sheath 1 notch inboard (referring to accompanying drawing 3); The nearly cutter hub 2 end both sides of handle of a knife 5 respectively are provided with a spill tail 6, and the tongue of spill tail 6 is near cutter hub 2; The nearly spill tail 6 end both sides of handle of a knife 5 respectively are provided with a clinching shell fragment 4, the tongue (referring to accompanying drawing 2) of clinching shell fragment 4 end conflict spill tails 6.

The utility model is provided with sheath 1, the handle of a knife 5 of simple and easy practical safety, and it is firm again fast that sheath 1 is packed, extracted to cutter hub 2 into, and handle of a knife 5 is held partly bow shape design, meets the ergonomics regular movements.Sheath 1 and handle of a knife 5 pack into combine after, extract when using, toward interior pressure, utilize lever principle to both sides, clinching shell fragment 4 end, the catching groove 3 of pushing sheath 1 aside can be easily, safety be extracted cutter hub 2 again fast and be used.When sheath 1 and handle of a knife 5 will be packed into when combining,, promptly safe firm again as long as cutter hub 2 inserts according to sheath 1 notch; Because the catching groove 3 of sheath 1 and sheath 1 is integrally moulded by obdurability, good springiness has intensity again, can reach demand for security.

Above illustrated embodiment is only with for conveniently illustrating the utility model, be not that the utility model is done any pro forma restriction, have in the technical field under any and know the knowledgeable usually, if in the scope that does not break away from technical characterictic that the utility model is carried, utilize technology contents that the utility model discloses to do the local equivalent embodiment that changes or modify, and do not break away from technical characterictic content of the present utility model, all still belong in the scope of the utility model technical characterictic.
