Abstract
The invention discloses a front fork outer pipe for a bicycle, comprising a left pipe body, a right pipe body and bridge connecting members spanning the upper ends of the left pipe body and the right pipe body; a pipe mouth through which a fixed front fork inner pipe is inserted is arranged at the upper end of the left pipe body; a grapping claw which is used for fixedly connecting a bicycle hub shaft is arranged at the lower end of the left pipe body; a pipe mouth through which a fixed front fork inner pipe is inserted is arranged at the upper end of the right pipe body; a grapping claw which is used for fixedly connecting the bicycle hub shaft is arranged at the lower end of the left pipe body; the bridge connecting members are two arch bridge connecting members of which the middle parts are arched; two ends of the two arch bridge connecting members are respectively and integrally connected with the left pipe body and the right pipe body; the middle parts of the two arch bridge connecting members are integrally formed into a reinforcing bar; a pair of support legs is formed at each end part of the two arch bridge connecting members and is integrally connected with the pipe mouth at the upper end of the left pipe body or the right pipe body; and the support legs at the same side of the two arch bridge connecting members are respectively positioned at the pipe mouth of the left pipe body or the right pipe body. According to the front fork outer pipe disclosed by the invention, the connection strength between the front fork outer pipe and the bicycle hub shaft as well as the connecting strength between the front fork inner tube and a front fork vertical pipe are enhanced; meanwhile, the appearance design of the front fork outer pipe is attractive.
Description
Technical field
The present invention relates to the improvement of bicycle front fork pipe fitting, particularly a kind of front fork outer pipe for bicycle that strengthens front fork outer tube Joint strenght.
Background technology
In the prior art, as shown in Figure 1, front fork outer pipe for bicycle is by left body 1, right body 2 and be connected across this left body 1 and right body 2 upper ends between bridging fitting 3 form, the front wheel hub spindle colludes pawl 12 by two of this left body and right body lower end, 22 support and connection, and two mouths of pipe 11 of this left body 1 and right body 2 upper ends, 21 can fix two front fork inner pipes 41 for inserting respectively, 42, this two front fork inner pipe 41,42 are connected and fixed (this part shows) by head tube seat 5 and front fork vertical bar 6 again in Fig. 4, these head tube seat 5 two ends are fixedly welded on this two front fork inner pipe and middle part and this front fork vertical bar 6 are welded and fixed.Insert fixedly front fork inner pipe for the ease of this left body 1 and the right body 2 upper end mouths of pipe, these bridging fitting 3 two ends respectively one are connected in the same lateral edges of this left body 1 and right body 2 upper ends, but be connected to be prone between front-wheel hub axle and front fork outer tube, front fork inner pipe and the front fork vertical bar in the cycle racing process and rock poor stability.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of front fork outer pipe for bicycle, strengthen Joint strenght between front fork outer tube and bicycle hub axle, front fork inner pipe and the front fork vertical bar, simultaneously appearance design is also attractive in appearance.
Technical scheme of the present invention is such realization: a kind of front fork outer pipe for bicycle, by left body, right body and be connected across this left body and the bridging fitting of right body upper end forms, this left body upper end has can be for inserting the fixedly mouth of pipe of front fork inner pipe, and the lower end has the pawl that colludes that is connected and fixed bicycle hub axle, this right body upper end has can be for inserting the fixedly mouth of pipe of front fork inner pipe, and the lower end has the pawl that colludes that is connected and fixed bicycle hub axle, this bridging fitting is the middle two arch bridge attaching partss that are arch, these two arch bridges attaching parts two ends respectively with this left body be connected the body one and be connected, and integrally formed at least one reinforced rib between the middle part.
As a further improvement on the present invention, an integrally formed reinforced rib between this two arch bridges attaching parts middle part.
As a further improvement on the present invention, a pair of feet that each end in this two arch bridges attaching parts forms, this is connected with left body or right body upper end mouth of pipe one feet.
As a further improvement on the present invention, the feet of homonymy evenly is positioned at the mouth of pipe of this left body or right body in this two arch bridges attaching parts.
Useful technique effect of the present invention is: described front fork outer tube adopts two arch bridge attaching partss and left body and is connected the body one and is connected, be provided with again reinforced rib between this pair arch bridge attaching parts, so that the bridging fitting is more firm, meanwhile this pair arch bridge attaching parts both ends are connected with left body or right tube mouth edge one, therefore also do not affect this left body or right body and insert fixing for front fork inner pipe.
Because a pair of feet that each end in this pair arch bridge attaching parts forms, the feet of homonymy evenly is positioned at the mouth of pipe of this left body or right body in this pair arch bridge attaching parts simultaneously, design like this so that this pair arch bridge attaching parts and left body and right body are fixing more reliable and more stable, thereby improve stability between front fork vertical bar and the bicycle hub axle.

The specific embodiment
A kind of front fork outer pipe for bicycle, by left body 1, right body 2 and be connected across this left body and the bridging fitting of right body upper end forms, this left body 1 upper end has can be for inserting the fixedly mouth of pipe 11 of front fork inner pipe, and the lower end have be connected and fixed bicycle hub axle collude pawl 12, these right body 2 upper ends have can be for inserting the fixedly mouth of pipe 21 of front fork inner pipe, and the lower end have be connected and fixed bicycle hub axle collude pawl 22, this bridging fitting is the middle two arch bridge attaching partss 31 that are arch, 32, these two arch bridges attaching parts two ends respectively with this left body 1 be connected body 2 one and be connected, and an integrally formed reinforced rib 33 between the middle part, the a pair of feet that each end in this two arch bridges attaching parts forms, every pair of feet is connected this two arch bridges attaching parts 31 with left body or right body upper end mouth of pipe one, the feet of homonymy evenly is positioned at the mouth of pipe of this left body 1 or right body 2 in 32.
As shown in Figure 4 and Figure 5, based on above-mentioned front fork outer tube, the middle part of a head tube seat 5 is fixed in front fork vertical bar 6 lower ends of bicycle, two front fork inner pipes 41,42 upper end are fixed in these head tube seat 5 two ends, this two front fork inner pipe 41,42 inserts respectively and is fixed in this left body 1 and right body 2, and colluding pawl 12,22, two on this left body 1 and the right body 2 be respectively applied to be connected and fixed bicycle hub axle, because this front fork outer tube adopts two arch bridge attaching partss, both strengthened firmly firm between front fork vertical bar and the bicycle hub axle, outward appearance is also reasonable.
