Abstract

The utility model relates to a vertical tube fixing structure, which comprises an upper cover, a bolt and a packing component. The upper cover is provided with a pair of sleeve posts capable of being folded onto the top edge of a front fork pipe middle hole, an annular abut shoulder capable of being abutted to the top end of a vertical pipe and a screw head hole penetrating vertically. The bolt is provided with a bolt head capable of being correspondingly positioned to the screw head hole and a screw capable of extending into the front fork vertical pipe middle hole. The packing component is provided with an annular block, the annular block is provided with an inner screw hole for the screw to combine with in a penetrating manner, lower conical portions spaced in an increasing manner are arranged upwards on the periphery of the annular block in an extending spaced manner, a positioning portion with equal spacing is arranged upwards at the top end of each lower conical portion, upper conical portions spaced in a reducing manner are arranged upwards at the top end of the positioning portion in an extending manner, and the top ends of the upper conical portions are connected to the bottom face of the upper cover. Accordingly, when the bolt drives the packing component to move towards the direction of the upper cover in a screw manner, two positioning portions of the packing component are extended outwards to tightly match the front fork vertical pipe middle hole in order to fix the vertical pipe and the front fork vertical pipe together.

Description

The vertical tube fixed sturcture

Technical field

The utility model relates to the technical field of bicycle, is meant a kind of vertical tube fixed sturcture of bicycle especially.

Background technology

Please referring to Fig. 1, the involutory insertion of confession vertical tube of front fork 20 apical margins of standpipe of bicycle 10 endoporus 11 coaxial lines, make vertical tube 10 bottoms be located by the outstanding ring piece 21 of vertical tube of front fork 20 peripheries, vertical tube of front fork 20 then can be given prominence in its top, have a mesopore 22 as for 20 of vertical tube of front fork, make vertical tube 10, vertical tube of front fork 20 be fixed into one through a fixed sturcture then.

This fixed sturcture is made up of a loam cake 30, a bolt 40, a nut 50 and a packing ring 60; Described loam cake 30 has ring that a sleeve column 31, that can be matched with vertical tube of front fork 20 mesopores 22 apical margins can press on vertical tube 10 tops and supports shoulder 32, the consistent screw terminal hole 33 under putting on; Have the bolt head 41 that can corresponding be positioned screw terminal hole 33 as for 40 on bolt, and the screw rod 42 that can stretch into vertical tube of front fork 20 mesopores 22; And nut 50 is placed in vertical tube of front fork 20 mesopores 22, and its apical margin is formed with a shoulder 51, and provides an inner bolt hole 52 for screw rod 42 combinations in the central axis position; This packing ring 60 runs through for screw rod 42, make it be limited between loam cake 30 and the nut 50, this packing ring 60 has the snare 61 that can be positioned shoulder 51, upwards extend the hypocone 62 of spacing flaring then in snare 61 relative both sides, then upwards there is an equidistant location division 63 on these hypocone 62 tops, and these 63 tops, location division upwards extend the spacing convergent on tapering 64,64 tops, tapering can be adjacent to loam cake 30 bottom surfaces in the order.

Drive nut 50 when turn bolt 40 when loam cake 30 direction spiral shells move, this nut 50 just can tighten packing ring 60, make its hypocone 62, go up tapering 64 and can extend out interlock location divisions 63, in order to tightly fitting in vertical tube of front fork 20 mesopores 22, so that vertical tube 10, vertical tube of front fork 20 are fixed into one.

Yet this kind fixed sturcture has following shortcoming:

One, member is too many, causes manufacturing cost high;

Two, its nut 50 and packing ring 60 can not be the modularization setting for separating, except that cause packaging efficiency low, and when dismounting loam cake 30, the puzzlement that has part to lose easily;

Three, in the process that screws bolt 40, can produce relative rotation between packing ring 60 and the nut 50, packing ring 60 motion start up location division 63 is extended out, the application force that causes location division 63 to tightly fit in vertical tube of front fork 20 mesopores 22 is not enough to some extent.

In view of this, the design person is through after constantly research, testing and improve, and development and Design goes out a kind of vertical tube fixed sturcture finally, uses and improves above-mentioned disappearance.

The utility model content

The purpose of this utility model is to provide a kind of simple in structure and easy-to-disassemble and assemble vertical tube fixed sturcture, can strengthen the flush fit application force of vertical tube and vertical tube of front fork.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is:

A kind of vertical tube fixed sturcture, it includes: a loam cake has a ring that can involutory sleeve column in vertical tube of front fork mesopore apical margin, can press on the vertical tube top and supports shoulder, the consistent screw terminal hole under putting on; One bolt has the bolt head that can corresponding be positioned the screw terminal hole, the screw rod that can stretch into the vertical tube of front fork mesopore; An and packing assembly that is placed in the vertical tube of front fork mesopore, it has a ring piece, this ring piece provides can be for the inner bolt hole of this screw combinations, and upwards extend the hypocone of spacing flaring in this ring piece periphery both sides correspondence, then upwards there is a location division on two hypocone tops, and this top, two location divisions correspondence upwards extend the spacing convergent on the tapering, this is formed with an opening that passes through for screw rod in top, tapering on two, and can be connected to the loam cake bottom surface.

Described packing assembly is provided with the alar part that a level extends out between ring piece periphery and hypocone.

The utility model can also be a kind of vertical tube fixed sturcture, and it includes: a loam cake has a ring that can involutory sleeve column in vertical tube of front fork mesopore apical margin, can press on the vertical tube top and supports shoulder, the consistent screw terminal hole under putting on; One bolt has the bolt head that can corresponding be positioned the screw terminal hole, the screw rod that can stretch into the vertical tube of front fork mesopore; An and packing assembly that is placed in the vertical tube of front fork mesopore, it has a ring piece, this ring piece provides the inner bolt hole for screw combinations, and in encircling the hypocone that piece periphery both sides correspondence upwards extends the spacing flaring, then upwards there is a location division on two hypocone tops, and this top, two location divisions correspondence upwards extend the spacing convergent on the tapering, make this be formed with an opening that passes through for screw rod in top, tapering on two, and the top, tapering has extended connecting portion respectively on two.

Described connecting portion is arcuation and extends out setting.

Described loam cake is combined with the block of outstanding upper cover top surface.

The utility model adopts said structure, when bolt drives the packing assembly when loam cake direction spiral shell moves, can drive two location divisions of packing assembly are extended out, and makes it can tightly fit in the vertical tube of front fork mesopore, makes vertical tube, vertical tube of front fork be fixed into one; In a word, the utility model has following advantage at least:

1, the utility model becomes two with three simple elements of tradition, and manufacturing cost is effectively reduced.

2, the utility model packing assembly is that conventional screw cap, packing ring are integrated into a modular construction, except that can promoting the packaging efficiency, and when the dismounting loam cake, can effectively improve the puzzlement that part is lost.

3, in screwing the bolt process, rotation one angle of the location division of this packing assembly meeting rotary-cut more or less, so the application force that just can make the location division tightly fit in the vertical tube of front fork mesopore promotes to some extent.
