1, structural strength is weakened: the end of its spring 12 must be cut to establish and be scabbled end 120, make and scabble end 120 end weakness very, and spring 12 is when stressed, and its stress concentrates on this and scabbles on the end 120, causes this end very easily to destroy, and necessity of improvement is arranged in fact.

2, processing is difficult for: its spring 12 must be cut in this end to set out again and scabble end 120 after moulding, not only increases the program of spring 12 constructions, has more therefore improved the construction reject ratio of spring 12, and the cost of construction is increased relatively.

3, support effect is limited easily to cause deflection: its end of scabbling end 120 plane fixed base 14 that only has been sticked, fixed base 14 is for very limited of the supportive of spring 12 ends, and, if scabbling when holding 120 infringement is arranged of its spring 12, its spring 12 can't keep its form parallel with central shaft 112, so when pressurized, its spring 12 very easily has improperly, and distortion causes deflection, the outwards direction of breeches pipe 111 distortion, cause blocking with outer breeches pipe 111, and the buffering that makes outer breeches pipe 111 moves and is subjected to improper blocking, for the effect of buffering bad influence arranged.

The purpose of this utility model is to provide a kind of spring fixed seat with compensation locating effect, and spring is stablized more really with the location that combines between fixed base, makes fixed base can obtain splendid support effect, has more the effect of compensation correction deformation angle.

The technical solution of the utility model is:

A kind of spring fixed seat with compensation locating effect is to be provided with fixed base in spring end, it is characterized in that:

The outside that fixed base exposes spring be provided with area bigger against edge, stretch against the mediad spring centre of edge and to be provided with a positioning part, and stretching out the top system edge of circular arc in positioning part outer rim place, oblique radian that this top system edge is provided with is identical around oblique radian with the circle of spring forming.

Described spring fixed seat with compensation locating effect is characterized in that: this fixed base is upwards vertically stretched outside the edge and is provided with revetment, clamps spring end inside and outside the positioning part with the cooperation fixed base.

Described spring fixed seat with compensation locating effect, it is characterized in that: the relative two groups of springs of these fixed base both ends of the surface are oppositely arranged two groups of identical structures.

Described spring fixed seat with compensation locating effect is characterized in that: this fixed base stretches out positioning part and top system edge respectively against the edge both ends of the surface.

Described spring fixed seat with compensation locating effect, it is characterized in that: this fixed base is provided with revetment against the edge periphery.

The utility model has the advantages that:

1, improve spring 12 structural strengths really: the end that its spring 12 cooperates with fixed base 20 need not any other processing or cutting and grinding construction processing, not only can reduce the program of construction, last burden reduces cost, more guarantee the intensity of spring 12 structures, reduce the stress application of force and destroy possibility, improve the life-span of spring 12 uses.

2, proofreading and correct support effect effectively improves: the end of its spring 12 is inboard to support for the positioning part 22 of fixed base 20 really, more cooperate spring 12 ends to hold the location really with fixed base 20 top system edge 23 with oblique arc, effective support is lived spring 12 ends, reduction spring 12 that can be certain is because of being subjected to the possibility of the improper distortion of stress side direction, and during its spring 12 pressurizeds, make edge 23 driving fit location more with the top, its effect of proofreading and correct support is more direct effectively.

3, the effect that has mutual compensation: because the top system edge 23 of its spring 12 end arc gradients and 22 outsides, fixed base 20 positioning parts is suitable, when fixed base 20 is cooperated with spring 12 location, it has naturally and aligns and compensating action, and fixed base 20 and spring 12 are incorporated on the position of the best.

4, the stability of location is high: it is except that having above-mentioned spring 12 and high stability position structure that fixed base 20 cooperates, more cooperate by large-area the resistance with other structures against edge 21, it is stable against form that fixed base 20 and spring 12 combining structures and the resistance of other structures are fitted in, and makes integral body become the structure of a high stability.
