Abstract
The present invention discloses the connecting part between tool handle and tool head, and is especially one kind of connecting core rod for connecting hollow tool handle of composite material and tool head. The present invention features that the reinforcing core is provided with outer plastic layer. Compared with available technology, the present invention has the advantages of high strength, long service life, saving in timber, simple production process, etc.
Description
Technical field:
The present invention relates to the connection plug of a kind of connector of pad, particularly a kind of stick of composite material hollow tool handle, be mainly used in being connected between the hollow pad of tool head and composite.
Background technology:
At present, the lever that is connected on all kinds instrument in agricultural tools, gardens gardening and engineering mostly is the hollow lever of composite greatly, being connected between lever and the instrument, be to adopt a wooden connector to connect, it is the fastening insertion that matches of the endoporus of end of wooden connector and hollow lever, the fastening insertion that matches of the other end of wooden connector and the installing hole on the tool head couples together tool head and lever.This wooden connector has following shortcoming: at first, owing to be wooden connector, for reaching the condition of use, requiring material must be the hard wooden of high-quality, annually consumes a large amount of forest reserves; The second, owing to be wood materials, modification and rotten causes entire tool not use for a long time easily; Three, because several times of the wooden height of strength ratio of the tool handle of composite, cause the stressed connecting portion that concentrates on tool head and tool handle of entire tool, wooden connector does not reach the requirement of strength that is complementary with lever.
Summary of the invention:
The purpose of this invention is to provide a kind of intensity height, long, the connection plug of saving the stick of composite material hollow tool handle of timber resources of burn into life-span, overcome the deficiencies in the prior art.
Technical solution of the present invention is: a kind of connection plug of stick of composite material hollow tool handle is characterized in that: the outside that strengthens core 1 is provided with plastic outer layer 2.
Described enhancing core 1 is synthetic material or metal.
Described synthetic material is thermosetting fabric reinforced plastics or thermoplastics type's fibre reinforced plastics.
The present invention compared with prior art has following advantage: intensity is high and stable: because of the connector that adopts high-intensity enhancing core to make, intensity is several times of wood materials; In addition owing to there is not wood materials suction phenomenon such as rot, for a long time proof strength stablize constant.Long service life.The product design dimensionally stable: product is once typing, and specification is stablized constant, does not have the phenomenon of wooden suction shrink modification, has improved the precision of assembling.Technology is simple: adopt the bar made by the glass fibre enhancing resin plastics (comprising thermosets and thermoplastic) of pultrusion or compression molding or the tubing enhancing inner core as connector; Perhaps adopt rod that metal material makes or pipe as strengthening inner core, outerly adopt common injection machine, the mould that can make according to the shape of different requirements, the moulding of injection heat moulding material.Owing to be common technology, easily grasp good operation.When using this product, saved a large amount of timber resources.
Description of drawings:
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment:
As shown in Figure 1: 1 for strengthening core, and 2 for being coated on the skin that strengthens core 1 outside.The material that strengthens core 1 can be synthetic material or metal.Described synthetic material can be selected heat curing-type fiberglass reinforced plastics or thermoplastic glass fibre reinforced plastics for use.Make by pultrusion or compression molding device.The enhancing core of making 1 can be rod or tubulose; Perhaps adopt rod that metal material makes or pipe as strengthening core 1, outer 2 adopt common injection machine, the mould that can make according to the shape of different requirements, the moulding of injection heat moulding material.During installation (is example with the spade), in the head installing hole on the tapered part insertion spade in left side, the endoporus that the right side cylindrical section inserts stick of composite material hollow tool handle gets final product.
