Description
Technical field
The present invention is relevant with cutter, is meant a kind of floating cutter structure especially.
Background technology
The blade of general cutter is normally metal, and the proportion of whole cutter is more great than the ratio of water, therefore, when using cutter in various waters, as at sea, fishing pond or river bank etc., will submerged when cutter drops, want to drag for to pick up really and be not easy.
Therefore in order to make weight saving and the solid lever intensity of holding concurrently, even the cutter of wood or plastics lever is arranged, because be that the solid whole proportion of cutter that still can make is more great than the ratio of water, so the weight of convention cutter is still heavier.Though perhaps have weight to alleviate, cause structural strength not enough, the problem that exists cutter to damage easily.Therefore above-mentioned tool structures still has and much treats improvements.
Summary of the invention
To the problems referred to above, main purpose of the present invention is to provide a kind of floating cutter structure, and the change that it utilizes material and method for making reduces the whole proportion of cutter structure, can float in the water, can make blade combine to form conveniently the intensity of solid lever of can holding concurrently again.
For achieving the above object, a kind of floating cutter structure provided by the present invention is characterized in that including: a blade has the end that a blade and a fixed part are formed at said blade; One lever; It is molded to increase the blowing agent foaming heat with plastic material, and its appearance forms clad surface, innerly simultaneously forms some closed air chambers independently separately; Said lever has the fixed part that a blade portion of connecing coats said blade fully; One grip part connects to establish and is formed at the end that said blade meets portion, and a medium altitude chamber is formed at said grip part, and wherein sealing is equipped with air.
In the technical scheme of the invention described above, the plastic raw materials of said lever be polypropylene (Polyproylene, PP) or polyethylene (Polyethylene, PE).
The end of said lever is the convergent taper.
Said lever has the medium altitude chamber that an opening is opened said lever.
Also include a seal, said seal has the opening that a piston part seal cover is located at said lever.
The material of said seal is rubber or flexible plastic.
The opening of said lever is for to be gradually-reducing shape to its end direction.
The shared volume of the closed air chamber of said lever makes the whole proportion of floating cutter structure less than one.
Adopt technique scheme, the present invention utilizes the change of material and method for making, adds foaming and molding with plastic material; After being shaped, the lever of cutter just has even curface; And produce some closed air chambers that fill up air, the whole proportion of cutter structure is reduced, and can float in the water.In addition, this structure makes that blade combines to form conveniently, and the intensity of solid lever of can holding concurrently.

Fig. 1 is the three-dimensional combination figure of the present invention's one preferred embodiment;
Fig. 2 is the vertical view of the present invention's one preferred embodiment;
Fig. 3 is the side-looking combination section of the present invention's one preferred embodiment;
Fig. 4 is the partial enlarged view of Fig. 3.
The specific embodiment
In order to specify structure of the present invention, characteristic and effect, existing following preferred embodiment of act and conjunction with figs. explanation are as follows.
Like Fig. 1～shown in Figure 4,, include by the present invention's one preferred embodiment is provided a kind of floating cutter structure:
One blade 10 has the end that a blade 11 and a fixed part 13 are formed at blade 11.
One lever 30; It is molded to increase the blowing agent foaming heat with plastic material; Make its appearance form clad surface 41, innerly simultaneously form some closed air chambers 45 independently separately, lever 30 has a blade and connects the fixed part 13 that portion 31 coats blade 10 fully; One grip part 33 connects to establish and is formed at the end that blade meets portion 31, and a medium altitude chamber 35 is formed at grip part 33 and opens an opening 37.
Wherein the end of lever 30 is the convergent taper, and opening 37 is gradually-reducing shape to its end direction.
In addition, also include a seal 50, it has the opening 37 that a piston part 51 seal covers are located at lever 30.
In addition, the assembly of present embodiment can be explained orally as follows in more detail, wherein:
The plastic raw materials of lever 30 be polypropylene (Polyproylene, PP) or polyethylene (Polyethylene, PE).
The material of seal 50 is rubber or flexible plastic, and combined in various manners such as available close-fitting, gummed or welding are in lever 30.
The whole proportion that the closed air chamber 45 shared volumes of lever 30 make floating cutter structure is less than one.
Therefore, lever 30 can reduce the whole proportion of cutter structure, floats in the water in order to it.
The manufacture process of present embodiment member, the existing explanation as follows:
At first, blade 10 is placed a mould (not shown), with the mould matched moulds; Then inject the polypropylene (Polyproylene that adds blowing agent; PP) or polyethylene (Polyethylene; PE) molten plastic gets in the die cavity; Make its fixed part that is coated on blade 10 13, this penetrates material i.e. clad surface 41, rib wall 43 and the closed air chamber 45 of foaming and formation lever 30 in die cavity; Then, this cutter of cooling taking-up gets final product.
The characteristics that can find this embodiment through above explanation are:
Polypropylene (Polyproylene, PP) or polyethylene (Polyethylene, PE) weight density of plastics be approximately 0.905 littler than water, adding foaming and the air chamber structure that painstakingly produces after its buoyancy more strengthen.
Moreover the clad surface 41 that forms lever 30 is not as sponge the space to be arranged, so the intensity of lever 30 is enough.
In addition; The proportion at this each position of cutter; Be the grip part 33 that the blade of blade 10, lever 30 connects portion 31 and lever 30 by size in regular turn, therefore front end is heavier and be easy to use when gripping, and its when swimming in the water be blade 10 down and the grip part 33 of lever 30 up; Therefore conveniently pick up and be difficult for quilt and hurt, have security preferably.
Another preferred embodiment of the present invention is identical substantially with last embodiment, and its difference is:
This cutter structure also can not comprise seal 50, directly with lever 30 integrally formed sealings; Perhaps, also can seal 50 and lever 30 one be fused.
In addition, lever 30 of the present invention also can adopt the structure of two-piece type butt joint, can conveniently make moulding like this, binds in addition or welding gets final product again.
In sum, after the explanation through the above embodiment of the present invention, can understand floating cutter structure provided by the present invention; It utilizes the change of material and method for making; Add foaming and molding with plastic material, just have even curface after the lever of cutter is shaped, and produce some closed air chambers that fill up air; The whole proportion of cutter structure is reduced, it can be floated in the water.In addition, this structure makes that blade combines to form conveniently, and the intensity of solid lever of can holding concurrently.
