Description

Bicycle use composite material seat cushion joint

The utility model relates to a kind of bicycle use accessory, especially a kind of bicycle use composite material seat cushion joint.

Traditional cycle frame and part are all made of metal, and it also is like this wherein being used for giving in to the seat cushion joint of managing in the linking with the seat cushion montant.As Fig. 1: Taiwan 76212171 novel patent cases disclose a kind of metallic joint, except the weight of vehicle frame own is big, after also the vehicle frame welding must being fixed aspect the processing, again whole vehicle frame is erected at the car system of carrying out joint endoporus 2 on the processing equipment, processing such as grinding are so that make joint 1 and middle pipe 3,4 sockets of seat cushion montant, this processing mode formality is loaded down with trivial details, and manufacturing cost is higher.

The purpose of this utility model be propose a kind of can simplified manufacturing technique, in light weight, tighten effective bicycle use composite material seat cushion joint.And so and pin-connected panel unitized construction of employing.

This usefulness is novel to be achieved in that

The utility model manufacturing assembling simple in structure can reach in light weight easily and tighten effective goal of the invention with montant.Joint is made with the carbon fiber material, only need after the moulding connector by using processing equipment is done endoporus processing, to offer the middle pipe gummed of two elasticity conduits affixed with a top again, and make the seat cushion montant directly be set in middle pipe middle part, when a bunching ring is tightened in this pipe top, make that composing the single-piece joint with middle pipe produces the effect of tightening to the seat cushion montant simultaneously.Simplified the manufacturing process of joint like this, also can reach lightweight and tighten the good effect of fruit.

Now further narrate structure of the present utility model and embodiment in conjunction with the accompanying drawings.

Referring to Fig. 2, the member that the utility model relates to comprises: joint 10, middle pipe 20, seat cushion montant 30, bunching ring 40, its center tap 10 are made with carbon fiber composite material, respectively be formed with a upper and lower belled position 11,12 at top, the two ends, the end of joint and the short slot 111 of two proper width and the degree of depth is set at the opening part of upper and lower belled position 11, in the port periphery one inclined downward 112 gradually from inside to outside is set, this external joint 10 a running-on 14.15 each side is set respectively with Seat stay 61 and go up pipe 62 sockets.

Middle pipe 20 is also made hollow tubular with carbon fiber composite material, can penetrate and protrude out from the following belled position 12 of this joint 10 on this above belled position 11, pipe 20 and the equal covered with glue in spatial accommodation 13 contact positions in being somebody's turn to do, and cooperate short slot 111 places of this joint 10 that two elasticity conduits 21 are set on its top, impel this elasticity conduit 21 to be and be symmetrical arranged, be provided with a larger-diameter location division 22 at suitable length place, distance top with short slot 111.

Manage 20 diameter during seat cushion montant 30 is matched with and set the aperture, make it exactly can be plugged in the inside of flexible conduit 21 ends of pipe racks in this.

Bunching ring 40 is made hollow and annular, form a top in inside and bring into the register hole 41 of smaller aperture due together, and in register hole, be provided with one and support only shoulder 411, so that pipe 20 tops during register hole 41 just can be set in, impel on the end face that ends shoulder 411 conflicts pipe 20 in this, form up-narrow and down-wide pushing away again in these shoulder 411 bottoms and pull out hole 112, just can be linked on the inclined-plane 112 of this joint 10.Periphery at bunching ring offers a breach 42, and these breach both sides are provided with a lug 43.44 respectively, and wherein a lug 43 central authorities are provided with in one.The boss hole 431 that contracts, another lug 44 central authorities are provided with a screw 441, one screws 50 and penetrate and be threaded with screw 441 from the interior boss hole 431 that contracts.

When this joint 10 is made moulding in mould after, need only utilize processing equipment to do endoporus processing, and be formed spatial accommodation 13 with appropriate accuracy.Immediately just can be at spatial accommodation 13 inner and in manage 20 location division 22 above position covered with glue, and pipe 20 is provided with elasticity conduit 21 1 ends and penetrates in the following belled position 12 of this joint 10 in will being somebody's turn to do, again by passing in the last belled position 11, when central pipe 20 ends protrude from belled position 11 end faces, elasticity conduit 21 must be aimed at short slot 111, after treating the adhesive drying, just can make joint 10 and middle pipe 20 bondings become integral body.And carbon fiber composite material is in case behind the gummed, its anchoring strength is quite high, can not break away from easily.

Referring to Fig. 3: with bunching ring 40 be set in earlier belled position 11 on this joint and in the top of pipe 20, impel shoulder 411 to resist pipe 20 tops in this, push away and pull out hole 412 and then be set on this inclined-plane 112, again seat cushion montant 30 is plugged in the inside of pipe 20 in this, can make in this belled position 12 ports down of just conflicting under these joint 10 bottoms, location division 22 of pipe 20, and obtain the correct positioning effect.Then screw 50 is locked between two lugs 43.44, can make each inter-module obtain temporary transient location.

Referring to Fig. 4: when screw 50 is locked between two lugs 43.44, and screw 50 is when continuing to lock, the width of this breach 42 is bigger, and not urgent last belled position 11 and middle pipe 20 tops of tightening this joint of register hole 41, and this moment, this seat cushion montant 30 can freely be managed 20 slides within this.As shown in Figure 5, when screw 50 is locked between two lugs 43.44, and when making the narrowed width of breach 42, this register hole 41 and push away also corresponding the diminishing in garden footpath of pulling out hole 412, can produce the effect of tightening to last belled position 11 and middle pipe 20 tops that are bonded to single-piece joint 10, in case when upward belled position 11 and middle pipe 20 are tightened, effect by short slot 111 and elasticity conduit 21 can make the top of joint 10 and middle pipe 20 be the state of bringing together, and fixing effect is tightened in 30 generations to the seat cushion montant.

The purpose on inclined-plane 112 is set is to produce when shrinking for belled position 11 is tightened by bunching ring 40 to belled position 11 outer peripheral edges on joint 10, can increase oar song, the plasticity at this position.Thereby guarantee to obtain better to combine effect between joint 10 and the middle pipe 20.
