Abstract
The utility model pertains to a three-dimensional veneer plywood structure used for table-tennis racket bottom plate. The table-tennis racket bottom plate consists of a sectional cementing layer in the middle and a panel on both sides; the sectional cementing layer consists of wooden single plies of different thickness and different materials alternately arranged; the wooden single plies are agglutinated through the sectional cementing layer; the panel is vertical with the sectional cementing layer and is agglutinated on both sides of the sectional cementing layer through a plane glue line; and the wooden single plies of the sectional cementing layer are radioactively distributed. The hardness, speed, flexibility, hand control and rotation of the utility model can fully meet the technical needs of 40mm-diameter large balls.
Description
The utility model belongs to a kind of three-dimensional laminated structure that is used for base plate of ping-pong bat.
Common table tennis bat covers glue bond in the plane by the wood chip veneer of the different numbers of plies and forms, and gummed uses the difference tree material of veneer to form different base plate of ping-pong bat structures with thickness, has also just determined the performance indications of ball plate.These indexs comprise elasticity, ball speed, rotation, control, Unit Weight, parameters such as thickness.
International Table Tennis Federation uses the big ball of table tennis of diameter 40mm regulation game from October, 2000, and progressively apply in whole table tennis in calendar year 2001.Big table tennis is in elasticity, speed, and rotation, volume has significant change on the parameters such as weight, and velocity of shuttle flight and rotation rotating speed lower to show that volume strengthens and the weight increase causes rattling, and the surface area change that contact with racket simultaneously causes flexibility decrease greatly.Cover the base plate of ping-pong bat that the normal plywood structure of glue bond is carried out parameter designing and making by original plane,, run into impassable obstacle on the performances such as elasticity and rotation, therefore can not overcome the negative effect that brings thus the table tennis technique and tactics in speed.
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of three-dimensional laminated structure that is used for base plate of ping-pong bat is provided, break through the elastic wave velocity of big table tennis and the technique and tactics obstacle in the rotation, be applied on the table tennis bat to satisfy the technique and tactics requirement of diameter 40mm table tennis.
Technical solution of the present utility model is: by the section cementing layer that is positioned at the intermediate layer be positioned at the base plate of ping-pong bat that the plate face of both sides is formed, it is characterized in that the section cementing layer is alternately rearranged by the timber monolithic of different-thickness unlike material, be bonded by the section glue-line between the timber monolithic, the plate face is bonded in the both sides of section cementing layer perpendicular to the section cementing layer by the plane glue-line.The timber monolithic of forming the section cementing layer is radioactivity at the plate face sends cloth.
The utility model not only covers glue on conventional plane, and on section, cover glue, form 3-D solid structure through the secondary hot pressing gummed, the space frame structure that the ultra-thin glue-line of three-dimensional laminated structure forms, the elastic modelling quantity of stiffener blank structure greatly, compared with the common plane glued board of condition of equivalent thickness, wood layer gummed is more even, intensity is bigger, is difficult for distorting.And break through the obstacle on the table tennis bat combination property of common gummed, in hardness, speed and elasticity and feel control and rotation, can fully be fit to the technique and tactics needs of the big ball of 40mm diameter.
Three-dimensional laminated structure is radioactivity at the plate face sends cloth, form the network structure of three-dimensional cementing layer, all use the very thin expanded bonding technique of glue that covers in three directions, intensity that its netted glue-line is extremely hard and ultra-thin tough performance overcome elasticity and the contradiction of controlling two kinds of performances in the normal plywood, form the excellent comprehensive performance.
In base arrangement of the present utility model, the radial strength of wide grained wood is brought the elasticity of base plate, the control and the rotation of the rotation direction intensity decision base plate of the perpendicular line timber of another layer; And have band and two kinds of wooden lines of perpendicular line simultaneously at the three-dimensional glued construction plate of one deck core, so the utility model structure forms a kind of special optimization line single structure plate anyhow, thereby brings table tennis bat control, rotation and excellent combination fast.
The network structure of three-dimensional laminated structure can absorb the vibrations of batting, strengthens feel and ball plate control ability.The combination of the wooden performance of pure natural of the present utility model is better than the base plate of ping-pong bat that the hard board of carbon and other fiber is made.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is an A portion enlarged drawing.
Below in conjunction with accompanying drawing the utility model is described in detail.Base plate 2 is made up of section cementing layer 1 that is positioned at the intermediate layer and the plate face 3 that is positioned at both sides, section cementing layer 1 is alternately rearranged by the timber monolithic 4,5,6 of different-thickness unlike material, be bonded by section glue-line 8 between the timber monolithic 4,5,6, plate face 3 is perpendicular to section cementing layer 1, be bonded in the both sides of section cementing layer 1 by plane glue-line 7, form the base plate of ping-pong bat 2 of three-dimensional laminated structure with three-dimensional cementing layer.Plate face wood grain is perpendicular to section cementing layer wood grain.Base plate thickness is 2.6-3.4mm.
The three-dimensional laminated structure of the utility model glues together for the first time to timber monolithic process earlier, forms section gummed aspect; Along the grain direction is carried out secondary gluing to the veneer and other the common plank that have perpendicular to the board plane cementing layer at in-plane along being processed into the veneer that has perpendicular to the board plane cementing layer perpendicular to cemented surface then.
Claims (2)
1, a kind of three-dimensional laminated structure that is used for base plate of ping-pong bat, form by section cementing layer that is positioned at the intermediate layer and the plate face that is positioned at both sides, it is characterized in that the section cementing layer is alternately rearranged by the timber monolithic of different-thickness unlike material, be bonded by the section glue-line between the timber monolithic, the plate face is bonded in the both sides of section cementing layer perpendicular to the section cementing layer by the plane glue-line.
2, the three-dimensional laminated structure that is used for base plate of ping-pong bat according to claim 1, the timber monolithic that it is characterized in that forming the section cementing layer is radioactivity at the plate face sends cloth.
