Abstract

A clamping holder structure shared by both a bicycle transverse handle and a standpipe, comprising a front clamping body and a rear clamping body equipped on the front position and rear position of a clamping holder. In front of and behind the blocking holder, a cupped circular arc slot is provided transversely and erectly, respectively, so that the faces of the front clamping body and the rear clamping body that joint the clamping holder are the transverse cupped circular arc slot and the erect cupped circular arc slot. Through-shaped smooth round holes and through holes are provided around the clamping holder and the front clamping body; and tap holes are provided around the rear clamping body, so that after the clamping holder, the front clamping body and the rear clamping body wrap and clamp the transverse handle and the standpipe, stay bolts of relative quantity are put through the through holes of the front clamping body and then pass through the smooth round holes of the clamping holder and then reach the tap holes of the rear clamping body to be jointed, simplifying manufacture of the entire clamping holder and reducing scape ratio.

Description

The holder structure that bicycle cross handle and vertical tube are shared

Technical field

The utility model relates to a kind of bicycle handle holder structure, the holder structure that particularly a kind of bicycle cross handle and vertical tube are shared.

Background technology

Present assembling morphology (as Fig. 1) about vertical tube A in the bicycle and cross handle B, system by one be horizontal in-line holder C respectively forwardly weldering have a semicircle concave arc body D and weldering knot one circle folder bundle body E in the wings, wherein the periphery at this semicircle concave arc body D is shaped on tapped bore D1, think again and come double team cross handle B by a semicircle concave arc clamp E who is relative moulding, after bolt G1 then passed the through hole F1 of this semicircle concave arc clamp F periphery, screw lock forms in the tapped bore D1 of semicircle concave arc body D to be close to; And restraint body E at a circle folder of holder C knot that weld at the rear, in this circle folder bundle body E one position, be provided with profile groove E1, and distinctly be welded with several protuberances E2 in the both sides of this profile groove E1, and on protuberance E2, make circle and bore a hole and tapped bore, it is set in this circle folder bundle body E inwall for vertical tube A, lives by bolt G2 locking double team more afterwards.

Yet with such assembling mode, at first belong to round shape moulding cause, make on making to be not easy, especially need some attached peripheral Fabricating machinerys holder C, semicircle concave arc body D, circle folder bundle body E three itself; The circle folder bundle body E weldering knot at the semicircle concave arc body D in this holder C and the place ahead and rear also is time and the cost that increases on making again; Again, owing to need the making of tapped bore at semicircle concave arc body D, circle folder bundle body E periphery, it is very difficult will making screw thread at the arc surface end, so that just be easy to generate scrap, relatively will weld the knot object on arc surface also is not simple thing, therefore also be easy to produce scrap, and also will whether be enough to deal with, bear external vibrations with respect to the intensity after making; So all making are that puzzlement is many really.

Therefore, the applicant then gives and develops the utility model case at above problem, and then proposes the application of this patent.

Summary of the invention

Main purpose of the present utility model is, provides a kind of bicycle cross handle and vertical tube shared holder structure, can reach making that simplifies whole holder and the effect that reduces condemnation factor.

The utility model structure: the holder structure that a kind of bicycle cross handle and vertical tube are shared is made of a holder, front clamp and back clamp; It is characterized in that the place ahead of this holder has a horizontal depression arc groove, the rear has the depression arc groove of a disposed upright, and the holder periphery has the level and smooth circular hole that runs through; And in the front clamp with holder mutually the face of subsides place have horizontal depression arc groove, its periphery has through hole; In the back clamp with holder mutually the face of subsides place have the depression arc groove of disposed upright, its periphery has tapped bore; Holder, front clamp and back clamp coat respectively and paste folder cross handle and vertical tube, and overbolt is set in the level and smooth circular hole of the through hole of front clamp and holder, and screw togather fixing with the tapped bore of back clamp.

The utility model beneficial effect: by said structure, its processing simplifies, easily, and need not do the welding part reason again, also reduces the use to bolt quantity, and then reduced the loss condemnation factor in processing and fabricating.

The specific embodiment

At first, please cooperate shown in the detailed description of consulting Fig. 2: a kind of bicycle cross handle of the utility model and the shared holder structure of vertical tube, holder 1 is assembled with a front clamp 2 and back clamp 3, wherein, the horizontal depression arc groove 11 in the place ahead of this holder 1, then there is the depression arc groove 12 of a disposed upright at the rear, and be provided with the level and smooth circular hole 13 that is penetration state at its periphery, and in the front clamp 2 with holder 1 mutually the face of subsides place make horizontal depression arc groove 21, and be provided with the through hole 22 that is penetration state at its periphery, in the back clamp 3 with holder 1 mutually the face of subsides place make the depression arc groove 31 of disposed upright, and be provided with tapped bore 32 at its periphery; Thus, when holder 1, front clamp 2 and back clamp 3 are cross handle B and vertical tube A respectively coat paste press from both sides after (as Fig. 3-A, Fig. 3-B), then in the level and smooth circular hole 13 by the through hole that is placed through front clamp 2 22 of overbolt 4 and holder 1, screw togather to the tapped bore 32 of back clamp 3 again and be close to (as Fig. 4); So, processing is seemed simplify, easily, and need not do the welding part reason again, also reduce use, and then reduce loss condemnation factor at processing and fabricating to bolt quantity.

And, also holder 1, front clamp 2 can be made for the different shaped body of one, promptly clamp 5 (as Fig. 5-A), make its as the dress prescription formula of the same the above collocation back clamp 6 in conjunction with (as Fig. 5-B).

To sum up institute is old, and above-mentioned the utility model structure meets the establishment condition of novel patent; Earnestly ask the accurate legal monopoly power of awarding.

Claims

1. bicycle cross handle and the shared holder structure of vertical tube are made of a holder, front clamp and back clamp; It is characterized in that: the place ahead of this holder has a horizontal depression arc groove, and the rear has the depression arc groove of a disposed upright, and the holder periphery has the level and smooth circular hole that runs through; And in the front clamp with holder mutually the face of subsides place have horizontal depression arc groove, its periphery has through hole; In the back clamp with holder mutually the face of subsides place have the depression arc groove of disposed upright, its periphery has tapped bore; Holder, front clamp and back clamp coat respectively and paste folder cross handle and vertical tube, and overbolt is set in the level and smooth circular hole of the through hole of front clamp and holder, and screw togather fixing with the tapped bore of back clamp.
