Abstract

The utility model relates to a collision-resistant wooden steering wheel which comprises a hollow annular base body. A plurality of grooves and a plurality of bended arc parts positioned among the grooves are arranged on the base body. The side ends of the grooves are separable, and each bended arc part is an independent unit body. The interior of the base body is formed by the clamping arrangement of a plurality of gunny layers and a plurality of fine bamboo (wood) fibrous layers at intervals, wherein, a log sheet is coated on the outer part of one side of the base body to form the collision-resistant wooden steering wheel which has good traction force and toughness and ensures personal safety.

Description

The wooden bearing circle of crash-proof

The utility model relates to a kind of device of bearing circle, particularly relates to a kind of pulling force, toughness is good and guarantees the wooden bearing circle of crash-proof of personal safety.

Flourish along with economy, life is day by day rich, people have not been only limited to the instrument of riding instead of walk for the demand of vehicle, and for decoration, the outfit of vehicle interior, more can promote vision, touch feeling when driving a car.

In order to cater to the demand of present customer for wooden accessory, a kind of wooden bearing circle is arranged, as shown in Figure 1, coat and be fixed with several layers of wooden ring plate 2 and foaming body 3 on the circular frame bar 1 at interval in being, and be covered with thin skin leather 4 in foaming body 3 external packets.

In the above-mentioned wooden bearing circle, the setting of this wooden ring plate 2 provides the driver and is texture demand in vision, the sense of touch, but when unfortunate suffer a car accident or improperly external force do the time spent, the wooden ring plate 2 of this wooden bearing circle itself does not have special intensifying device, be easy to produce sharp portion because of fracture, and because bearing circle next-door neighbour steerman, the easier steerman that makes comes to harm.

Therefore, the purpose of this utility model is to provide a kind of pulling force, toughness all good and can not injure the wooden bearing circle of impact resistance of human body when steerman is subjected to external force collision.

In order to achieve the above object, the utility model proposes the wooden bearing circle of a kind of crash-proof, it comprises the matrix that hollow ring round and cross section are semicircle shape, and on a wherein side of matrix, be provided with a straight face of joint, and opposite side is provided with the circular-arc outer peripheral face of evagination, this outer peripheral face is provided with several grooves, and between two grooves, has an arc portion, be separable with groove and arc portion and arc portion is a cell cube independently, so that bearing circle is installed the preposition place, the inside of this arc portion is arranged with burlap layer partly by face of joint in regular turn towards outer peripheral face, on each burlap layer, respectively be provided with thin bamboo (wood) fibrage in the upper/lower positions again, coat one deck log thin slice again in the thin bamboo of the outermost that is symmetrical in outer peripheral face (wood) fibrage outside, therefore, can obtain the wooden sense of touch of tool, the bearing circle of vision and device intensity Cui.

Can be provided with a circular arc lead angle at the arc portion side that is connected with groove, and circular arc lead angle bottom and groove joining place right angle intersection.

Below by most preferred embodiment and accompanying drawing the wooden bearing circle of the utility model crash-proof is elaborated, in the accompanying drawing:

Fig. 1 is the exploded perspective view of general wooden bearing circle.

Fig. 2 is the schematic perspective view of the utility model first preferred embodiment.

Fig. 3 is the arc portion schematic perspective view of the above-mentioned preferred embodiment of the utility model.

Fig. 4 is the arc portion section-drawing of the above-mentioned preferred embodiment of the utility model.

Fig. 5 is the installing scheme drawing of the above-mentioned preferred embodiment of the utility model.

As Fig. 2, shown in 3, according to the wooden bearing circle of the crash-proof of embodiment of the present utility model, comprise hollow ring round and cross section and be a circular-arc matrix 100, a wherein side of this matrix 100 is provided with a face of joint 110 that is flat, and opposite side is provided with the circular-arc outer peripheral face 120 of evagination, several grooves that is recess 130 are arranged on this outer peripheral face 120, and constitute an arc portion 10 130 of two grooves, and be provided with a circular arc lead angle 140 at arc portion 10 sides that are connected with groove 130, and circular arc lead angle 140 bottoms and groove 130 bottom lands 131 joining places are right angle intersection, constitute a cut-out portion 132, after matrix 100 integral body are made, do to cut off action from cut-out portion 132, can constitute several arc portions 10 of separate unit body.

Cooperate shown in Figure 3, when arc portion 10 be cut off be the separate unit body after, utilize the setting of cut-out portion 132 and circular arc lead angle 140, make the both sides of arc portion 10 have flat end face, and avoid producing burr, and reduce the work programme at burr place, and as shown in Figure 5, with on the upper and lower frame bar 210 that butts up against bearing circle 200 of two arc portions 10 and constitute wooden bearing circle.

As shown in Figure 4, in the present embodiment, these arc portion 10 inside are arranged with four sections burlap layers 11 by face of joint 110 in regular turn towards outer peripheral face 120,12,13,14, and each burlap layer 11,12,13, on 14, upper/lower positions respectively is folded with thin bamboo (wood) fibrage 15 again, 16,17,18,19, burlap layer forms at interval with thin bamboo (wood) fibrage and is provided with, outside at the thin bamboo of the outermost that is symmetrical in outer peripheral face 120 (wood) fibrage 19 is coated with a log thin slice 19 again, each thin bamboo (wood) fibrage 15,16,17,18,19 bamboo (wood) fiber can with burlap layer 11,12,13,14 fiber is combined into one, when external force collision, utilize burlap layer 11,12,13,14 with thin bamboo (wood) fibrage 15,16,17,18,19 binding force, can increase single-piece device intensity, and 10 of arc portions can form tortoise (tearing) and split shape, and can not damage human body.

The mode of making of above-mentioned matrix 100, with bamboo (wood) fiber hybrid resin, hardener and form bamboo (wood) fibrestock, one deck bamboo (wood) fiber is former, one deck burlap layer is stacked one by one form after, be shaped to the blank of hollow ring round with mould heat pressure, again log thin slice and above-mentioned blank are inserted mould inside, carry out the hot pressing second time, and log thin slice and blank are combined into one, it is high temperature resistant to utilize bamboo (wood) fiber in the blank that it is had, characteristics such as waterproof, utilize burlap layer then can increase its pulling force and toughness, and utilize the natural lines of log thin slice, the wooden effect of beautifying of outward appearance then can be provided, in conjunction with after can make and have preferable structural strength between each constituent components, what deserves to be mentioned is, in the above-mentioned manufacturing process, it is the semicircle sheetmetal that lock is established the tool predetermined thickness in die cavity, so can utilize this sheetmetal on finished product, to form groove 130, and sheetmetal can adjust the position, and produce the arc portion 10 of different length specification in good time.
