Description

Bicycle connection pipe structure

Technical field

The utility model relates to a kind of bicycle connection pipe structure.

Background technology

As depicted in figs. 1 and 2, existing bicycle connection pipe structure, this connection pipe 10 is made of 11 of the middle pipes of a hollow, should in pipe 11 two ends be formed with respectively a horizontal base 12 with always to base 13, wherein horizontal base 12 can be established the handle tube 20 of horizontal expansion for group, directly to base 13 then can be established directly to the vertical tube of front fork 30 that extends for group, aforementioned connection pipe 10 is under the consideration of intensity, the projection shapes that middle pipe 11 utilizes base 12 to form supply the bolt interlocking, and make base about 12 and up and down the outer rim only can straight-line extension, cause the projection place of relative base 12 to be recess.

Therefore, with handle tube 20 behind interlocking with the equal rectangular shape of the joint of the joint of base 12 and middle pipe 11 and vertical tube of front fork 30, except that unfavorable control cable wear and dragline, and the folder bundle side face C1 of base 12 relative handle tubes 20 is the girth of round type, not only press from both sides the limited length of bundle, it is also not enough to coat area, have influence on the intensity of its locking, it is easily in the both sides corner formation focal point of stress of handle tube 20 with base 12 interlockings simultaneously, cause the situation of undercapacity, and the phenomenon that gets loose easily has influence on the safety of use, moreover, when handle tube 20 is subjected to the rider to turn to the application of force, because base 12 receiving area deficiencies, and the phenomenon of undercapacity is arranged, remote effect are to the application of force conduction that turns to, so remain further to be improved.

The utility model content

Technical problem to be solved in the utility model is: a kind of bicycle connection pipe structure is provided, it can be realized controlling the smooth and easy of cable and wear and dragline, make that also structural strength increases between the handle base at the middle pipe of connection pipe and two ends and standpipe base, increase the coating area of the relative handle tube of handle base simultaneously, and then improve the intensity of locking, further promote the conducting effect that turns to of the relative vertical tube of front fork of handle tube.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bicycle connection pipe structure, this connection pipe is made of pipe institute in, middle pipe two ends be formed with respectively a horizontal handle base and for the interlocking handle tube supply the interlocking vertical tube of front fork directly to the standpipe base; The angle outer rim of the corresponding handle tube in the handle base both sides of pipe is arranged with a lug in being somebody's turn to do, and the handle base left and right sides is expands outwardly shape; The angle outer rim of the corresponding vertical tube of front fork of the standpipe base of pipe is provided with a fin in being somebody's turn to do, and makes standpipe base root edge be the expansion shape; Pipe in-to-in hollow bulb during the both sides lug relative inner of described handle base forms and is communicated with; The fin inboard of described standpipe base also is formed with pipe in-to-in hollow bulb in the connection.

The beneficial effects of the utility model are: be the fin design of the angle outer rim that expands outwardly shape design and the corresponding vertical tube of front fork of standpipe base by the hand base left and right sides, make that the control cable can be from smooth and easy wearing in the base in one's hands in the handle tube, then smooth and easy wearing in the vertical tube of front fork, and make things convenient for dragline, make also that simultaneously structural strength increases between the handle base at the middle pipe of connection pipe and two ends and standpipe base, and increase the coating area of the relative handle tube of handle base, and then improve the intensity of locking, further promoted the conducting effect that turns to of the relative vertical tube of front fork of handle tube.

The utility model is described in further detail below in conjunction with accompanying drawing.

The specific embodiment

As Fig. 3, Fig. 4 and shown in Figure 5, a kind of bicycle connection pipe structure, this connection pipe 50 is made of 51 of the middle pipes of a hollow, should in pipe 51 two ends be formed with a leader's base 52 and the standpipe base 55 that axis and middle pipe 51 are vertical configuration respectively, wherein horizontal handle base 52 is for handle tube 60 windings of horizontal expansion, and directly to standpipe base 55 then can be for directly establishing for 70 groups to the vertical tube of front fork that extends; In pipe 51 handle base 52 be formed with for the ccontaining semi-circular projection that holds groove and cover plate and screw lock of handle tube 60, and in handle base 52 both sides the angle outer rim of corresponding handle tube 60 is arranged with a

lug

53,54, handle base 52 left and right sides are expand outwardly shape, to increase the girth and the area of bearing handle tube 60, and two

lugs

53,54 inboards also are formed with pipe 51 in-to-in hollow bulbs 530 in the connection, 540, to reduce

lug

53,54 weight, avoid increasing the weight of connection pipe 50, especially convenient control cable can be from smooth and easy wearing in the base in one's hands in the handle tube, also make simultaneously the folder bundle side face C2 of handle base 52 folder bundle handle tubes 60 be bevelled ellipticity (as shown in Figure 7), and increase the folder Shu Zhouchang of handle base 52 and the area of coating handle tube 60;

The standpipe base 55 of middle pipe 51 is formed with ring-like perforation and the lock section that places for vertical tube of front fork 70, the angle outer rim of standpipe base 55 corresponding vertical tube of front fork 70 is provided with a fin 56, make standpipe base 55 root edges be the expansion shape, and fin 56 inboards also are formed with pipe 51 in-to-in hollow bulbs 560 in the connection, to reduce the weight of fin 56, avoid increasing the overall weight of connection pipe 50, especially convenient control cable in the handle tube smooth and easy wear base in one's hands after, then smooth and easy wearing in the vertical tube of front fork also strengthened simultaneously the structural strength of 51 of standpipe base 55 and middle pipes;

In addition, this novel decapacitation facility is controlled outside wearing of cable and the dragline, and can strengthen the coating area and the folder Shu Zhouchang of handle base 52 relative handle tubes 60, and group constitutes a bicycle connection pipe structure person that locking intensity is good and lifting turns to conducting effect and strengthens the structural strength between standpipe base and middle pipe.

Again as shown in Figure 6 and Figure 7, after connection pipe 50 is with handle base 52 and standpipe base 55 difference interlocking handle tubes 60 and vertical tube of front fork 70, can allow the rider see through the pivotal orientation that connection pipe 50 is controlled vertical tube of front fork 70 with handle tube 60, and by the handle base 52 of its connection pipe 50 when the interlocking handle tube 60, because handle base 52 both sides have

lug

53,54, except can be convenient to control cable wear and the intensity of dragline and increase handle base 52, it can make the joint of handle base 52 and handle tube 60 be and expand outwardly shape, allow the folder bundle side face C2 of handle base 52 relative handle tubes 60 be bevelled ellipticity, compared to can the increase substantially girth of its folder bundle of prior art, increase the area that coats simultaneously, and then improve the intensity of its locking, and the unlikely phenomenon that gets loose, to guarantee traveling security, and, when handle tube 60 is subjected to the rider to turn to the application of force, because the receiving area of handle base 52 both sides is big, so can promote the conduction that turns to the application of force, increase the sense of controlling that drives bicycle, moreover because standpipe base 55 root edge fins 6, it also can be beneficial to outside wearing of control cable and the dragline, and further can improve the intensity of connection pipe 50, competitiveness of product be can promote, its value added and economic benefit increased.
