Abstract

The utility model relates to a plastic-steel tool handle which comprises a metallic component which makes a reinforced bar and a steel pipe as frameworks, and the external sides of the frameworks are injected with compound handles which are combined by plastic protective sleeves. The utility model can be used as handles of tools, such as spades, shovels, hoes, picks, handles, etc. The tool handle replaces wood with plastic steel and saves valuable wood resources; regenerated plastic is sufficiently utilized; plastic-steel strength is favorable; deformation and damage are not easy to generate; the surface of the utility model is smooth without damaging hands; the utility model has the advantages of firm and durable performance, standardized bulk production, and long service life; the handle end is also provided with threads, and the utility model can directly make the tool heads, such as shovel heads, spade heads, hoe heads, handle heads, etc., which are manufactured by the threads, the metal and the plastic connected to be integration in order to manufacture various hand tools. The utility model has the advantages of light weight, convenient operation, convenient carrying and high safety.

Description

The plastic-steel pad

Technical field

The utility model relates to a kind of pad, particularly the plastic-steel pad that constitutes at the surface recombination plastic sheath as the steel pipe of skeleton, reinforcing bar.

Background technology

The hand tools spade that existing tradition is used, spades, iron palladium, iron pick, iron hoe and mop etc. are general all by wooden Shape handle and shovel head made of iron, shovel head, hoe, pick, the first-class integral body that is fixed into of mop, this handle for tool is rough, easily grind hand, handle and tool heads junction intensity difference, and timber is yielding, easily loosening, fragile, this type of instrument is in great demand in addition, be the consumer goods that have a large capacity and a wide range, therefore need expend a large amount of timber resources every year.

The patent No. 94228937.4 " is moulded the wooden spade handle of bag " though a kind of iron clad spade handle of moulding also is provided, but he increases by a plastic sheath at the handle place of spade handle, making handle surfaces, smooth not grind hand durable, firm, but it still adopts wooden handle, also needs the natural resources timber of consume valuable.

The patent No. 01259293.5 " welding impression the handspike spade " just provides a kind of spade handle, and it adopts the handle of steel-tube construction to improve intensity and safety in utilization, but the steel pipe price expensive, easily get rusty.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of plastic-steel pad is provided, economizes valuable timber resources with plastic-steel for knaur, pad smooth surface, intensity are good, but long service life is produced in standardization in batches.

The technical scheme in the invention for solving the above technical problem is: the plastic-steel pad, include metalwork, and described metalwork is as skeleton, and the compound handle that is injected with the plastic sheath composition outside skeleton constitutes.

Compared with prior art, advantage of the present utility model is: the plastic-steel pad, with the plastic-steel replacing wood, saved valuable natural timber resource, make full use of regenerated plastics, plastic-steel pad intensity is good, and smooth surface is not hindered hand, not yielding, not fragile, sturdy and durable, but standardization is produced in batches.Skeleton is steel pipe, reinforcing bar, and not direct ingress of air also is difficult for getting rusty.The instrument pommel also can be injected with screw thread, can directly and with screw thread and steel, the shovel of moulding system, spade, pick etc. link into an integrated entity, and it is in light weight, and use, easy to carry, safety have enlarged the scope of application, long service life.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Skeleton adopts steel pipe 5 to make, for reduce cost, weight reduction, the no steel pipe in the inside, place does not stress in the upper end that handle 3 reaches the handle that is connected with handle, being connected the inside, stressed place in the centre of handle with spade with the lower end has steel pipe 5, and the outer surface mold injection plastic sheath 4 at steel pipe 5 is combined into whole compound handle hollow spade handle 1, as Fig. 1, Fig. 2, shown in Figure 3, steel pipe 5 length are less than the length of spade handle 1, and are attractive in appearance for increasing, and at handle 3 and place, aperture, lower end stopple 2 and stopple 6 are housed.

Skeleton adopts steel pipe 10 to make, and is combined into mold injection plastic sheath 9 and the soft sheath 8 of moulding that a big end down end seals, the hollow helve 7 of an end opening at the outer surface of steel pipe 10, as Fig. 4, Fig. 5, shown in Figure 6., good hand touch comfortable for using, there are ripple and the soft sheath 8 of moulding in the pommel place of holding, and steel pipe 10 length are less than helve 7 length.

Skeleton adopts steel pipe 13 to make, outer surface mold injection plastic sheath 12 at steel pipe 13, be combined into whole thin, the following thick hollow mopstick 11 of going up, as Fig. 7, Fig. 8, shown in Figure 9, steel pipe 13 length are significantly smaller than the length of mopstick 11, only in the lower end and the mop cloth cooperation place of mopstick 11 steel pipe 13 are arranged.

Skeleton adopts reinforcing bar 17 to make, and at reinforcing bar 17 outer surfaces usefulness mold injection plastic sheath 16, has been combined into handle 15 and hollow, and following have screw thread 18 and solid stairstepping spade handle 14, and as Figure 10, Figure 11, shown in Figure 12, reinforcing bar 17 length are less than spade handle 14 length.

To be threaded whole on the screw thread on the spade handle 14 18 and the plastics shovel head 19, be exclusively used in and the 19 supporting uses of plastics shovel head, as shown in figure 13.
