Abstract

The utility model provides a standpipe clamping seat for the bicycle front Y-type pipe, the straight perforation of which is arranged on the Y-type pipe made of the carbon fiber materials, and then connects with the transversely placed handle bar being clamped by the sunken groove on the other end and the clamping seat cover, while the middle part of the straight perforation appears to be scooping shaped, on the upper and lower of the outer side of which is separately arranged with a bundle of rings that respectively equips with a groove falling into two sides of the different axes, with a horizontal circle perforation and inner screw hole on the two sides. Therefore, even force application can be reached to lock and fix so as to avoid the Y-type pipe fracture caused by the concentrating force application.

Description

The vertical tube holder structure of bicycle front fork pipe

Technical field

The vertical tube holder structure of a kind of front fork structure of bicycle of the utility model, particularly bicycle front fork pipe.

Background technology

The material that relevant front fork tube adopted is constantly being improved, and from the carbon fiber material that traditional iron material develops into aluminium, aluminum alloy, widely uses up till now, it serves to show that industry has sizable essence progressive on technical level; Yet all there is the obvious progressive while on vehicle frame and accessory, understood (as Fig. 1-A with the existing vertical tube holder B structure that is assembled on the front fork tube A,-B), the end of this vertical tube holder B is provided with straight perforation B1, and on its outside, respectively have one to be the profile groove B2 that communicates in the following two positions with straight perforation B1, and in the profile groove B2 both sides of same linearity (as Fig. 1-B,-C) be provided with a flat circle to bore a hole and inner bolt hole, so, come the horizontal handlebar E of double team to do by other end horizontal perforation with holder lid D more afterwards and combine by being screwed into of bolt C with on the front fork tube A that is installed in vehicle frame; Yet when being assembled, but find: because front fork tube A makes with the carbon fiber material, when the straight perforation B1 of vertical tube holder B when being packed in front fork tube A, but its application of force of tightening concentrates on two profile groove B2 positions of same linearity, so that the position of tight bundle causes the application of force excessive and produce the damage situation of breaking on the contrary easily, therefore demands urgently overcoming, solving.

Therefore, the applicant then develops out the utility model case at above situation, and proposes the application.

Summary of the invention

The utility model purpose is, a kind of vertical tube holder structure of bicycle front fork pipe is provided, and to overcome the defective of above-mentioned conventional confguration, can be equably the application of force causes the front fork tube fracture phenomena to be locked to avoid the application of force to cross concentrated.

According to the utility model, a kind of vertical tube holder structure of bicycle front fork pipe, the straight perforation in this vertical tube holder is arranged in the front fork tube made from the carbon fiber material, and horizontal handlebar double team is combined between the recessed groove and holder lid of this vertical tube holder other end; Wherein have the breach that hollows out at the straight perforation midway location, the breach upper and lower position respectively has a beam ring, and two beam rings of upper and lower position have a profile groove that communicates with straight perforation more respectively, and has a flat circle perforation and an inner bolt hole in the profile groove both sides; It is characterized in that: the two positions place of the different axis that stagger about this two profile groove is positioned at.

The utility model beneficial effect: pass through said structure, screw in the position when the flat circle of the other upper and lower two positions of straight perforation is bored a hole to inner bolt hole with bolt on the front fork tube, because the diverse location cause that staggers about the profile groove in these upper and lower two beam rings is divided into, can be equably the application of force in the profile groove of two diverse locations, and make its tight bundle power obtain equal configuration state, and then reach and be locked, avoided crossing and concentrated the phenomenon that causes front fork tube to break because of the application of force.

The specific embodiment

At first, please cooperate shown in the detailed description of consulting Fig. 2-A, B:

The vertical tube holder structure of a kind of bicycle front fork pipe of the utility model, be used for the front fork tube 1 made with the carbon fiber material, straight perforation 21 in this vertical tube holder 2 is installed on the front fork tube 1 in the vehicle frame, comes the horizontal handlebar of double team 4 to do by the recessed groove 24 of the other end with holder lid 3 more afterwards and combines; Wherein be the breach that hollows out at these vertical tube holder 2 straight perforations 21 midways location, respectively to be formed with a beam ring 22 in upper and lower position, the outside, and two beam rings 22 of upper and lower position be respectively equipped with again one with straight perforation 21 profile groove 23 for communicating, and be provided with a flat circle perforation 231 and an inner bolt hole 232 in profile groove 23 both sides, and the position, both sides of the different axis that two profile grooves 23 stagger about being divided into; And 24 4 jiaos a screw 241 is arranged respectively at the recessed groove of vertical tube holder 2, fix (as Fig. 3) by the perforation 31 around the holder lid 3 through bolt 3A cartridge clip again after inserting for handlebar 4.

When the straight perforation 21 of vertical tube holder 2 is placed on the front fork tube 1, when screwing in flat circle perforation 231 at straight perforation 21 other upper and lower two positions to inner bolt hole 232 with bolt 2A (as Fig. 4-A), because the profile groove 23 in these upper and lower two beam rings 22 is distributed in diverse location cause (as Fig. 4-B, C), can be equably the application of force in the profile groove 23 of two diverse locations, and make its tight bundle power obtain equal configuration state, and then reach and be locked, thus, can avoid because the application of force is crossed and concentrated and cause front fork tube 1 fracture phenomena.

Claims

1. the vertical tube holder structure of a bicycle front fork pipe, the straight perforation in this vertical tube holder is arranged in the front fork tube made from the carbon fiber material, and horizontal handlebar double team is combined between the recessed groove and holder lid of this heavily fortified point pipe clamp seat other end; Wherein have the breach that hollows out at the straight perforation midway location, the breach upper and lower position respectively has a beam ring, and two beam rings of upper and lower position have a profile groove that communicates with straight perforation more respectively, and has a flat circle perforation and an inner bolt hole in the profile groove both sides; It is characterized in that: the two positions place of the different axis that stagger about this two profile groove is positioned at.
