Description

Durable goal bat

The utility model relates to a kind of wooden club of durable gate-ball mallet, particularly described gate-ball mallet, and it is made of Wooden phenolic resin layer material.

Existing gate-ball mallet is made up of excellent handle and wooden club.When the user impacted spheroid with bat, the phenomenon of wooden club colliding surface or scrape along the ground usually took place.Along with the batting number of times increases gradually, wooden club contacts partly more and more serious with the wearing and tearing of batting part with ground, gate-ball mallet is scrapped fully.Existing gate-ball mallet is shorter usually service life.The well known materials that is used to make the croquet wooden club has impregnation nylon cloth, vulcanie, compressed wood and lamination wood.The common door bat unit weight made from these materials is low, and hardness is little, poor flexibility, and property is crisp, easily split, not wear-resisting, poor water resistance.

In order to overcome above-mentioned defective, those skilled in the art has been made many trials, so that overcome above-mentioned defective.In the disclosed CN-2111126U of Patent Office of the People's Republic of China, put down in writing a kind of gate-ball mallet, wherein adopted polyethylene and nylon to make high strength and high-quality gate-ball mallet.The unit weight of this gate-ball mallet is low, and wearability and usability are all undesirable.

In the disclosed patent documentation CN-2079976U of another piece Patent Office of the People's Republic of China, set forth a kind of gate-ball mallet that can increase the service life, when the wooden club of this bat one lateral wearing in use frequent and the collision on the ground friction is serious, excellent handle and wooden club can be taken apart, reinstall then, the position that the conversion wooden club contacts with ground makes the intact side of wooden club as normal and contacted position, ground.Though prolonged the service life of this wooden club, its wearability does not improve.

In order to overcome above-mentioned defective, prolong the service life of gate-ball mallet, improve the hardness of wooden club, strengthen its wearability, strengthen unit weight, be the key of dealing with problems.

The purpose of this utility model will overcome above-mentioned defective exactly, and a kind of long service life is provided; The hardness height, the gate-ball mallet that wearability is strong, unit weight is big.

The durable gate-ball mallet that provides herein comprises excellent handle and wooden club, and wherein wooden club is made of Wooden phenolic resin layer material.Have the roughly the same impregnation rift grain veneer of the grain of wood and wooden club longitudinal axis in the described timber phenolic resins layer material, the grain of wood roughly becomes horizontal impregnation face crossing and oiling impregnation veneer with the wooden club longitudinal axis.

The rift grain veneer group that the top layer of described Wooden phenolic resin layer material is made up of 1～10 layer of impregnation rift grain veneer.Thickness direction along described material is provided with 10～20 groups of impregnation rift grain veneer groups, 1～10 layer of impregnation rift grain veneer (1) arranged in every group of rift grain veneer, one deck oiling impregnation veneer can be set between adjacent impregnation veneer, thickness direction along institute's material, be provided with 5～19 layers of oiling impregnation veneer evenly distributedly, at the adjacent thickness direction that is soaked with between the veneer, be provided with 2～19 layers of gluing face crossing evenly distributedly.

Between adjacent impregnation veneer, the layer of metal net can also be set.Along the thickness direction of described material, turn up the soil and be provided with 2～8 layers of wire netting in the space.Impregnation rift grain veneer in described Wooden phenolic resin layer material, impregnation face crossing, oiling impregnation veneer, and total number of plies of wire netting is 43～246.

In the technical scheme that provides, the veneer of employing is 0.2～2.5 millimeter rotary-cut plate or a slicing plate.The glue of dipping veneer is 20～50% water soluble phenolic sol solution.The suction glue amount of veneer is 30～40%.In order to prevent that in manufacture process Wooden phenolic resin layer material from producing longitudinal crack, be provided with the impregnation face crossing along the even compartment of terrain of the thickness of lamination material, in order to overcome the crisp shortcoming of water soluble phenol resin lamination material, in described Wooden phenolic resin layer material, along the thickness direction of material, evenly the compartment of terrain is provided with the impregnation veneer that the top layer is coated with organic oil.Added this veneer that is coated with organic oil in the lamination material after, the wooden club fragility that produces is reduced greatly, toughness increases substantially, and resistance to water is further strengthened.

In order to reduce the fragility of water soluble phenolic bakelite matter layer material, improve the wearability of this material, elasticity and impact resistance, in the lamination material, also be provided with 2～8 layers of spaced wire nettings, wire netting is formed by steel wire or copper wire braiding usually, and wherein the gauge or diameter of wire of braided metal net is 0.2～0.5 millimeter.Adopt specification 25～30 orders of wire netting.

Because the position that is worn of wooden club appears at the side away from excellent handle place usually, therefore, wire netting is arranged in the zone that the central plane of wooden club and side away from excellent handle place surround.Wooden club wearability height with this structure, good springiness, impact resistance is strong, and serviceability is good.

By top description as can be seen, the technical scheme that provides of the utility model has overcome the shortcoming that exists in the prior art effectively.After the wearability of wooden club improves, prolong the service life of gate-ball mallet greatly, reduced the consumption of wooden lamination material simultaneously.

Below in conjunction with accompanying drawing technical characterictic of the present utility model is described in further detail, this will help those skilled in the art to be well understood to the utility model more.

Fig. 1 is the schematic diagram with gate-ball mallet of broken section.

Fig. 2 is the partial sectional view of the croquet wooden club that local A amplifies among Fig. 1.

Fig. 3 and Fig. 2 are similar, are the cutaway views of the local A of croquet wooden club shown in Figure 1.

A kind of durable gate-ball mallet that the utility model provides as shown in Figure 1, it comprises excellent handle (10) and wooden club (20), wooden club (20) is made of timber phenolic resins layer material.In described Wooden phenolic resin layer material, have four kinds of plane stratified materials usually, i.e. impregnation rift grain veneer (1), impregnation face crossing 92), oiling impregnation veneer (3), and wire netting (4).
