Description

Bicycle front fork

Technical field

The utility model relates to bicycle assembly, is meant a kind of front suspension fork of bicycle with room especially.

Background technology

The bicycle front fork that generally has shock-absorbing function mainly comprises unit block such as pipe and Connection Block in front fork outer tube, the front fork, and outer tube is made up of a left body and a right body, and each body bottom is fixed on the colored Grains of bicycle, and the body top then is open end face; Interior pipe includes the identical hollow sleeve of two structures, and each sleeve pipe tail end is inserted in respectively in the above-mentioned body, and the sleeve pipe head end then is designed to closed, and affixed two sleeve pipe head ends are then distinguished at the Connection Block two ends, makes two sleeve pipes simultaneously relative light-emitting diode body produce longitudinal travel.Bicycle front fork also is equiped with a Buffer Unit respectively in the common space that forms between each sleeve pipe and each body, common Buffer Unit is the elastic component (as the glue post of hollow) of coil tension spring or most compressible distortion, Buffer Unit one end contact forms fixed pivot at body bottom inner face, the other end then contact at the cannula tip inner face, according to Buffer Unit stored energy when the confined state, and when support state, discharge the characteristic of energy storage, reach the effect of damping.

The above-mentioned composition that is the Regular Bicycle front fork.With regard to this field, its technical development is perhaps near ripe, and is relatively can improved again place few, yet this case designer still in line with the spirit of innovation with contribution, relies on the development Experience of being engaged in the sector accumulation for many years, revest the function that adds up to this part, generation of the present utility model is arranged then.

Summary of the invention

Main purpose of the present utility model provides a kind of bicycle front fork, it is under the prerequisite of the damping effect that does not influence bicycle front fork, a wherein internal stent that constitutes front fork is designed to an accommodation space, can the relevant peripheral accessory collection of bicycle is wherein ccontaining.

Secondary objective of the present utility model provides a kind of bicycle front fork, and it can reduce the cost expenditure of bicycle front fork.

In order to achieve the above object, a kind of bicycle front fork provided by the utility model includes: a right support, and by Guan Yuyi outer tube mutual sheathed composition in one, interior pipe is outer tube generation displacement relatively; One left socle, also by Guan Yuyi outer tube mutual sheathed composition in one, interior pipe is outer tube generation displacement relatively; A connecting seat, its two ends connect the interior pipe apical margin of each support respectively, make each interior pipe can produce displacement action together; It is characterized in that: right support inside is equiped with a Buffer Unit; The interior pipe inside of left socle is formed with an accommodation space, and an opening is positioned at the pipe top end and is connected with accommodation space; One end cap is located at the interior tube opening place of aforementioned left socle with the mode group of dismantled and assembled combination.

Fig. 3 is the scheme drawing that the internal stent collection of the utility model front fork has article.

The specific embodiment

Enumerate preferred embodiment of the present utility model below, and conjunction with figs. is elaborated.

As shown in Figure 1, the composition of the utility model bicycle front fork 100 includes a right support 10, a left socle 20, two linings 30, two axles 40, a connecting seat 50, a Buffer Unit 60 and an end cap 70.Wherein:

Right support 10 and left socle 20 are all by 12,22 mutual sheathed compositions of pipe 11,21 and one outer tube in one, each outer tube 12,22 external bottom end is fixed in respectively on the axostylus axostyle of Yi Hua Grains (not shown) to form fulcrum, and in each pipe 11,21 can be relatively each outer tube 12,22 generation longitudinal travel, Connection Block 50 two ends connect the apical margin of pipe 11,21 in each respectively, make each interior pipe 11,21 can produce displacement action together; 30 of two linings are set in respectively between cooresponding interior pipe 11,21 outsides and outer tube 12,22 inner faces, and each interior pipe 11,21 that is arranged so that of each lining 30 can produce upper and lower displacements by more relative outer tube 12,22.

In addition, the bottom of pipe 11,21 has a shield 11 1,211 in each, offer a perforation 112,212 on each shield 111,211, two axles, 40 bottoms are fixed in outer tube 12,22 inner bottom places, axle 40 tops are then passed cooresponding perforation 112,212 and are stretched into interior pipe 11,21 inside, as shown in Figure 1, a block piece 41 is combined in axle 40 tops of right support 10, also is arranged with a spring 42 respectively in each axle 40 epimere outside;

In addition, each support 10,20 can be arranged with one or several respectively and be the damper element of middle hungry area post 43 in its axle 40 outsides, and glue post 43 provides the conflict buffer action when moving down for managing 11,21 in each.

Above-mentioned each support 10,20 that the utlity model has same structure that is, continue the architectural feature of the utility model front fork 100 is described below:

As shown in Figure 1, right support 10 is provided with a capping 13 at interior pipe 11 upper edges, opening with pipe 11 tops in sealing, and Buffer Unit 60 is managed 11 inside in being installed in, in the present embodiment, aforementioned Buffer Unit 60 is mainly the higher coil tension spring of an elasticity modulus 61, conflicts in interior pipe 11 inside top surface by coil tension spring 61 1 ends, and the other end is conflicted on the block piece 41 on axle 40 tops.But have stored energy when the confined state according to coil tension spring 61, and when support state, discharge the characteristic of energy storage, reach the effect of damping.

The interior pipe 21 inner accommodation spaces 23 that form of left socle 20, one opening 24 is positioned at pipe 21 top ends and is connected with accommodation space 23, pipe 21 apical margin inner faces in one internal thread segment 25 is arranged on, and end cap 70 has an external thread section 71 and a pulling part 72, external thread section 71 can cooperate with internal thread segment 25 and is spirally connected, and 72 of pulling parts use for the switching contact that internally to manage 21 mutually with control end cap 70 serve as combination or detached position; In addition, there is pad that a rubber makes to end part 26 plugs to be located in the left socle 20 pipe 21 inner and be positioned at top, axle 40 tops, supports the inner and outer pipes that the distance of ending between part 26 and axle 40 tops is front fork and can do flexible stroke distances as supporting.

More than be the structure of the utility model bicycle front fork 100, mandatory declaration be, because of the composition structure of front fork 100 only at right support 10 inner installing Buffer Units 60, so the utility model elite select have the higher elasticity coefficient coil tension spring 61 to keep the good damping effect that front fork 100 should have; As for pipe 21 inner formed accommodation spaces 23 in the left socle 20, then can be used as the less article of collection volume and use.

As Fig. 2, application examples shown in Figure 3, the tail end that is bicycle inflator special A that volume is less is fixed on the end cap 70 in advance, then, Floor Pump A is inserted in the accommodation space 23, Floor Pump A is for being inverted shape, Floor Pump A head end gently supports and ends part 26, afterwards, end cap 70 lock knots pipe 21 upper edges in left socle 20 are got final product, like this, can can remove from and carry difficult or the puzzlement of plug-in inconvenience for the rider provides more thorough preparation.Certainly, also some service toolies can be placed in the accommodation space 23, have equally and carry easy advantage; In addition, when taking out Floor Pump A, aforementioned pulling part 72 makes things convenient for user's hand to press usefulness.

Therefore, bicycle front fork 100 of the present utility model is not when influencing existing shock-absorbing function, an internal stent wherein is designed to collect the accommodation space of article, not only can provides the relevant peripheral accessory of bicycle wherein ccontaining, and can reduce the cost expenditure of shock-damping structure.
