Abstract
The invention relates to a floating tool structure which is characterized by comprising a blade and a grab handle, wherein the blade is provided with an edge part and a fixed part formed at one end of the edge part; the grab handle is fabricated by foaming and thermoplastic forming of a plastic material added with a foaming agent; a coating surface is formed on the surface of the grab handle; meanwhile, a plurality of independent closed air chambers are formed in the grab handle; the grab handle is provided with a blade connecting part, a grabbing part and a hollow accommodation chamber, wherein the blade connecting part completely coats the fixed part of the blade; the grabbing part is connected and arranged at one end of the blade connecting part; the hollow accommodation chamber is formed at the grabbing part; and air is sealed and accommodated in the hollow accommodation chamber. The grabbing handle of the tool can reduce the overall specific weight of the tool structure so as to be beneficial to floating on water.
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, therefore the weight of known cutter is still heavier.Though perhaps there is weight to alleviate, cause the structural strength deficiency, the problem that exists cutter to damage easily.Therefore the structure of above-mentioned cutter still has and much treats improvements.
Summary of the invention
At 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 convenient in conjunction with forming, 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 described blade; One lever, it is molded to increase the blowing agent foaming heat with plastic material, its appearance forms clad surface, simultaneously innerly form some closed air chambers independently separately, described lever has the fixed part that a blade portion of connecing coats described blade fully, one grip part connects to establish and is formed at the end that described blade meets portion, and a medium altitude chamber is formed at described grip part, and wherein sealing is equipped with air.
In the technical scheme of the invention described above, the plastic raw materials of described lever be polypropylene (Polyproylene, PP) or polyethylene (Polyethylene, PE).
The end of described lever is the convergent taper.
Described lever has the medium altitude chamber that an opening is opened described lever.
Also include a seal, described seal has the opening that a piston part seal cover is located at described lever.
The material of described seal is rubber or flexible plastic.
The opening of described lever is for to be gradually-reducing shape to its end direction.
The shared volume of the closed air chamber of described 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 blade convenient in conjunction with forming, and the intensity of solid lever of can holding concurrently.

Fig. 1 is the three-dimensional combination figure of a preferred embodiment of the present invention;
Fig. 2 is the vertical view of a preferred embodiment of the present invention;
Fig. 3 is the side-looking combination section of a preferred embodiment of the present invention;
Fig. 4 is the partial enlarged view of Fig. 3.
The specific embodiment
In order to describe structure of the present invention, feature and effect in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.
As Fig. 1～shown in Figure 4,, include by a preferred embodiment of the present invention 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, simultaneously innerly 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 explain 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 closed air chamber 45 shared volumes of lever 30 make the whole proportion of floating cutter structure 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 now is described 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 enters 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 by 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 when it swims in the water be blade 10 down and the grip part 33 of lever 30 up, therefore conveniently pick up and difficult the incised wound, 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 seal 50 and lever 30 one can 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, is binded in addition or welding gets final product again.
In sum, after the explanation by 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 blade convenient in conjunction with forming, and the intensity of solid lever of can holding concurrently.
