Abstract
The utility model relates to a tail pedal pipe which comprises a tail pedal pipe body (1), wherein a connecting hole (1.1) is formed at one end of the tail pedal pipe body (1); the tail pedal pipe is characterized in that the connecting hole (1.1) is a stepped hole consisting of an outer straight-through hole (1.1.2) and an inner straight-through hole (1.1.1); the outer straight-through hole (1.1.2) is formed at the outer end of the connecting hole (1.1); the inner straight-through hole (1.1.1) is formed at the inner end of the connecting hole (1.1); and the diameter of the outer straight-through hole (1.1.2) is greater than that of the inner straight-through hole (1.1.1). The working procedures are fewer, and the working efficiency is higher when the tail pedal pipe is connected with an outer pipe.
Description
Technical field
The utility model relates to the vehicular spare parts field, specifically is that a kind of tail is stepped on pipe.
Background technology
It is a accessory on the automobile that tail is stepped on pipe, common and outer tube assembles, generally being outer tube sleeve to be received tail step in the connecting bore of pipe during assembling, is clear opening because existing tail is stepped on the connecting bore of pipe, and the outer tube coupling end is not of uniform size stepped, step on pipe when being connected with tail, usually elder generation connects slim sleeve at the smaller part cover of outer tube coupling end, steps on the fastness that pipe is connected to guarantee outer tube and tail, when adopting this kind mode to produce, production process increases to some extent, and work efficiency is lower.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of when being connected with outer tube, the tail that operation is less, work efficiency is higher is stepped on pipe.
The technical scheme that the utility model adopts is: provide a kind of tail to step on pipe, comprise that tail steps on tube body, the end that described tail is stepped on tube body is provided with connecting bore, the stepped hole that described connecting bore is made up of outer clear opening and internal straight-through hole, described outer clear opening is located at the outer end of connecting bore, described internal straight-through hole is located at the inner of connecting bore, and the diameter of described outer clear opening is greater than the diameter of internal straight-through hole.
After adopting above structure, the utility model tail is stepped on pipe following advantage: the connecting bore of stepping on pipe owing to tail is stepped hole, stepped hole is made with the shape of the outer tube that will be connected and is matched, when assembling, directly the coupling end cover of outer tube being received tail steps in the stepped hole of pipe, do not need to use slim jacket casing to receive the coupling end of outer tube, reduced the operation of assembling, the efficient of assembling is improved.
As preferably, the outer end of described outer clear opening is provided with chamfering, can make things convenient for outer tube sleeve to receive tail and step in the connecting bore of pipe.
As preferably, described chamfering is 45
0, be an embodiment, convenient processing.

Among the figure, 1, tail steps on tube body, 1.1, connecting bore, 1.1.1, internal straight-through hole, 1.1.2, outer clear opening, 2, slim sleeve, 3, outer tube.
The specific embodiment
The utility model is described in more detail below in conjunction with drawings and Examples.
As shown in Figure 3, Figure 4, the utility model tail is stepped on pipe, comprise that tail steps on tube body 1, the end that tail is stepped on tube body 1 is provided with connecting bore 1.1, the stepped hole that connecting bore 1.1 is made up of outer clear opening 1.1.2 and internal straight-through hole 1.1.1, and outer clear opening 1.1.2 is located at the outer end of connecting bore 1.1, the right-hand member of connecting bore 1.1 among Fig. 3 just, internal straight-through hole 1.1.1 is located at the inner of connecting bore 1.1, the left end of connecting bore 1.1 among Fig. 3 just, and the diameter of outer clear opening 1.1.2 is greater than the diameter of internal straight-through hole 1.1.1.
The outer end of outer clear opening 1.1.2 is provided with chamfering, and just the right-hand member of outer clear opening 1.1.2 is provided with chamfering.
The utility model in the specific implementation, internal straight-through hole 1.1.1 and outer tube 3 than the small end socket, can adopt interference fit, the magnitude of interference is 0.02 ~ 0.04mm, is 20 by chamfering between outer clear opening 1.1.2 and the internal straight-through hole 1.1.1
0Transition phase connect, it is 45 that the right-hand member of outer clear opening 1.1.2 is provided with chamfering
0, make things convenient for the socket of outer tube 3.
The utility model is when assembling, directly the coupling end cover of outer tube 3 being received tail steps in the stepped hole of tube body 1, do not need to use slim sleeve 2 covers to receive the coupling end of outer tube 3, reduced the operation of assembling, the efficient of assembling is improved, when adopting protocercal tail to step on the pipe assembling, class's output is 600 cover/people, when adopting the utility model tail to step on the pipe assembling, the output 1200 cover/people of class have improved output greatly.
Claims (3)
1. a tail is stepped on pipe, comprise that tail steps on tube body (1), the end that described tail is stepped on tube body (1) is provided with connecting bore (1.1), it is characterized in that: the stepped hole that described connecting bore (1.1) is made up of outer clear opening (1.1.2) and internal straight-through hole (1.1.1), described outer clear opening (1.1.2) is located at the outer end of connecting bore (1.1), described internal straight-through hole (1.1.1) is located at the inner of connecting bore (1.1), and the diameter of described outer clear opening (1.1.2) is greater than the diameter of internal straight-through hole (1.1.1).
2. tail according to claim 1 is stepped on pipe, it is characterized in that: the outer end of described outer clear opening (1.1.2) is provided with chamfering.
