Abstract

The utility model relates to a plastic-coated wood or bamboo core tool handle which comprises a handle core made of solid wood or a wood rubber sheet or a bamboo rubber sheet or leftover materials thereof, a hand-grasp rack made of a steel bar, a steel frame made of a steel bar, and a plastic-coated layer outside the handle core, wherein the plastic-coated layer is formed through injection molding via a large-tonnage injection molding machine, the steel frame is mounted at the tail end of the handle core through solid rivets, and the handle core and the hand-grasp rack are connected as an integral body. The core tool made of inexpensive materials such as solid wood or a wood rubber sheet or a bamboo rubber sheet or the like is advantaged by smooth surface; rich diversity of appearances; colors that can be changed at will; completely-sealed property; waterproof property; prevention of the phenomena such as moisture regain moisture regain, mildew, worm damage, fracture, and the like; and upgrade from a low-end tool handle to a high-end product. The high-grade tool handle with high added value can be produced by using the most inexpensive leftover wood or bamboo materials.

Description

A kind of plastic wood, bamboo core handle for tool

Technical field

The utility model relates to a kind of handle for tool, particularly a kind of plastic wood, the handle for tool of bamboo core.

Background technology

At present, the production major part of five metals class building instrument is that assembling is complete after being made respectively by iron piece part and handle portion, wherein uses the building instrument of long handle solid wood handle to be representative with steel shovel, steel shovel, pick mattock, steel rake, steel hoe, iron hammer, reaping hook etc.The handle major part that this kind tool uses is circular solid wood handle; Fraction uses composites such as wood glue plate, bamboo offset plate to be processed into round handle, brushes one deck paint back in handle surfaces then and installs plastic cement or the iron back of shaking hands in the handle for tool end additional and be made into tool set with iron piece and sell, use.

The handle for tool that uses this kind traditional handicraft to manufacture out gets damp again easily, mouldy, damage by worms, rupture, defect rate is very high, yield rate is generally below 70%.Product specification is low, the waste raw material are serious, loading weight is less.

The utility model content

The utility model is exactly in order to overcome the deficiency of above conventional tool handle, provides that a kind of raw material sources are extensive, cheap, reliable quality is wooden, the plastic handle for tool of bamboo core.The utility model is rich and varied with handle for tool smooth surface, the moulding of the new structure that cheap made forms, the random conversion of color, fully the sealing, waterproof; Can not occur moisture regain, mouldy, damage by worms, phenomenon such as fracture; Handle integral body integral body in each item strength test increases substantially, and ultra common solid wood far away, wood glue plate, bamboo offset plate are made handle pulling force, pressure test.The surface is fine and smooth; Not be used in the surface and use paint to handle, avoid, can use leftover pieces such as solid wood to make in enormous quantities fully because the flaw on wood, bamboo wood material surface produces substandard products, waste product; Reduce valuable wood, the wasting of resources of bamboo wood material, improve the service life of handle for tool.

To achieve these goals; The utility model adopts following technical scheme: the handle core that is processed into round or disciform handle for tool shape with solid wood, wood glue plate, bamboo offset plate or their leftover pieces; At the handle place of shaking hands steel bar is installed and is fixed in handle end as the frame of shaking hands with solid rivet; Soak at the handle tip of a branch then and mould processing, adopt the high-strength polypropylene plastics to whole handle one-shot forming and coating fully with the large-tonnage injection machine again, outside the handle core, form one deck covered plastics layer.So just can avoid handle occur moisture regain, mouldy, damage by worms, phenomenon such as fracture, increased the loading weight of handle, and yield rate improves greatly also.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Shown in figure (1); The utility model embodiment provides a kind of plastic wood, the handle for tool of bamboo core; Comprise the handle core of processing by solid wood, wood glue plate, bamboo offset plate or their leftover pieces 1, the covered plastics layer 4 of the frame 2 of shaking hands, steel skeleton 3 and the 1 external application large-tonnage injection machine injection moulding of handle core made from steel bar.

(1) adopt the leftover bits of various good-for-nothing timber, wood glue plate, bamboo offset plate etc., being machined to through wood-turning machine needs the handle of shape core 1;

(2) purchase high-intensity steel bar, machine-shaping to the handle shape of shaking hands is made the frame 2 of shaking hands, and each makes a call to 2 diameter 3mm circular holes at the steel bar two ends, is processed into steel skeleton 3 backs and is installed in the end of handle core 1 with solid rivet, makes the handle core 1 and the frame 2 of shaking hands connect into an integral body;

(3) buying polypropylene or vinyon are with forming covered plastics layer 4 behind the handle core 1 and the frame 2 usefulness large-tonnage injection machine disposal moldings of shaking hands.

Handle loading weight through after the high-strength polypropylene plastic overmold reaches more than the 180KG; Considerably beyond solid wood, wood glue plate, bamboo offset plate handle loading weight more than 2.2 times; The plastic handle loading weight that surpasses steel pipe, fiber rod and be inner core is more than 1.5 times; And surface treatment is smooth, feel is fine and smooth, not be used in the surface and uses paint to handle, and yield rate reaches more than 95%.

The utlity model has following several big advantage: simple in structure, easy to make; The handle for tool one-shot forming avoid moisture regain that traditional handle occurs, mouldy, damage by worms, the generation of phenomenon such as fracture; Improved the loading weight of handle, and also raising greatly of yield rate, raw-material wastes such as wood, bamboo reduced, the service life of having improved handle.

Claims

1. a plastic wood, bamboo core handle for tool, it is characterized in that: process the handle core with solid wood, wood glue plate, bamboo offset plate or their leftover pieces, the handle core is coated with covered plastics layer.

2. a kind of plastic wood according to claim 1, bamboo core handle for tool is characterized in that: make the frame of shaking hands with steel bar, and be fixed on handle end with solid rivet.
