Abstract
A bicycle front fork outer pipe comprises a left pipe body, a right pipe body and a bridge connecting part in bridge joint with the upper ends of the left pipe body and the right pipe body. An orifice arranged at the upper end of the left pipe body can be used for inserting and fixing a front fork inner pipe while a hook claw arranged at the lower end is fixedly connected with a bicycle wheel hub shaft, an orifice capable of being used for inserting and fixing the front fork inner pipe is arranged at the upper end of the right pipe body while a hook claw arranged at the lower end is fixedly connected with the bicycle wheel hub shaft, the bridge connecting part comprises two arch bridge connecting parts with arched middles, two ends of each arch bridge connecting part are respectively integrally connected with the left pipe body and the right pipe body, the middles of the two arch bridge connecting parts are integrated to form a reinforcing rib, a pair of supporting feet are formed at each end of each arch bridge connecting part and integrally connected with the orifice at the upper end of the left pipe body or the orifice at the upper end of the right pipe body, and the supporting feet on the same sides of the two arch bridge connecting parts are evenly positioned on the orifice of the left pipe body or the orifice of the right pipe body. The bicycle front fork outer pipe strengthens connecting strength of the front fork outer pipe with the bicycle wheel hub shaft and connecting strength of the front fork inner pipe with a front fork vertical rod, and simultaneously is beautiful in appearance design.
Description
Technical field
The utility model relates to the improvement of bicycle front fork pipe fitting, particularly a kind of bicycle front fork outer tube that strengthens front fork outer tube Joint strenght.
Background technology
In the prior art, as shown in Figure 1, the bicycle front fork outer tube is by left body 1, right body 2 and the cross-over connection bridging fitting 3 between this left side body 1 and right body 2 upper ends is formed, bicycle front-wheel hub axle colludes pawl 12 by two of this left side body and right body lower end, 22 support and connection, and should left side body 1 and two mouths of pipe 11 of right body 2 upper ends, 21 can fix pipe 41 in two front forks for inserting respectively, 42, pipe 41 in this two front fork, 42 are connected and fixed (this part shows) by base 5 and front fork vertical bar 6 again in Fig. 4, these base 5 two ends are fixedly welded on pipe in this two front fork and the middle part is fixed with 6 welding of this front fork vertical bar.Fixedly manage in the front fork for the ease of this left side body 1 and the 2 upper end mouths of pipe insertions of right body, these bridging fitting 3 two ends one respectively are connected in the same lateral edges of this left side body 1 and right body 2 upper ends, but be connected to be prone between pipe and the front fork vertical bar in front-wheel hub axle and front fork outer tube, the front fork in the cycle racing process and rock poor stability.
Summary of the invention
In order to remedy above deficiency, the utility model provides a kind of bicycle front fork outer tube, strengthens Joint strenght between front fork outer tube and cycle hub axle, the interior pipe of front fork and the front fork vertical bar, and appearance design simultaneously is also attractive in appearance.
The technical solution of the utility model is such realization: a kind of bicycle front fork outer tube, by left body, right body and cross-over connection are formed in the bridging fitting of this left side body and right body upper end, this body upper end, left side has can be for inserting the fixedly mouth of pipe of the interior pipe of front fork, and the lower end has the pawl that colludes that is connected and fixed the cycle hub axle, this body upper end, right side has can be for inserting the fixedly mouth of pipe of the interior pipe of front fork, and the lower end has the pawl that colludes that is connected and fixed the cycle hub axle, this bridging fitting is the middle two arch bridge attaching partss that are arch, these two arch bridges attaching parts two ends are connected with right body one with this left side body respectively, and integrally formed at least one reinforced rib between the middle part.
As further improvement of the utility model, an integrally formed reinforced rib between this two arch bridges attaching parts middle part.
As further improvement of the utility model, 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 further improvement of the utility model, the feet of homonymy evenly is positioned at the mouth of pipe of this left side body or right body in this two arch bridges attaching parts.
Useful technique effect of the present utility model is: described front fork outer tube adopts two arch bridge attaching partss to be connected with right body one with left body, be provided with reinforced rib again between this pair arch bridge attaching parts, make that the bridging fitting is more firm, meanwhile this pair arch bridge attaching parts both ends are connected with left body or right body mouth of pipe edge one, therefore also do not influence this left side body or right body and insert fixing for pipe in the front fork.
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 side body or right body in this pair arch bridge attaching parts simultaneously, design makes this pair arch bridge attaching parts and left body and right body fixing more reliable and more stable like this, thereby improves stability between front fork vertical bar and the cycle hub axle.

The specific embodiment
A kind of bicycle front fork outer tube, by left body 1, right body 2 and cross-over connection are formed in the bridging fitting of this left side body and right body upper end, this left side body 1 upper end has can be for inserting the fixedly mouth of pipe 11 of the interior pipe of front fork, and the lower end have be connected and fixed the cycle hub axle collude pawl 12, these right side body 2 upper ends have can be for inserting the fixedly mouth of pipe 21 of the interior pipe of front fork, and the lower end have be connected and fixed the cycle 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 are connected with right body 2 one with this left side body 1 respectively, 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 side 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 base 5 is fixed in front fork vertical bar 6 lower ends of bicycle, the upper end of pipe 41,42 in two front forks is fixed at these base 5 two ends, pipe 41,42 inserts respectively and is fixed in this left side body 1 and right body 2 in this two front fork, and should left side body 1 and right body 2 on two collude pawl 12,22 and be respectively applied for and be connected and fixed the cycle 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 cycle hub axle, outward appearance is also reasonable.
