Abstract
The utility model discloses a kind of band flat spring mandrel, including flange and the stepped cylindrical being co-axially located in the flange first end face, the first end face of the stepped cylindrical is provided with the flat type mandrel in flat circle of position shape, the flat type mandrel includes the class cuboid mandrel that the relative side of one pair of which is in outer convex arc surface, a pair of radial direction jump-ring slots are symmetrically arranged with the outside of the head of the class cuboid mandrel, have straight trough the middle part of the class cuboid mandrel is axially arranged.The utility model is rational in infrastructure, and traditional cylindrical mandrel is arranged with into the class cuboid mandrel that a pair relative sides are in outer convex arc surface, can make to install interference phenomenon of rupture is occurred without after spring, and structure is safe and reliable, it is to avoid spring breakage.
Description
Technical field
The utility model is related to central spindle of the spring field, especially a kind of band flat spring mandrel.
Background technology
Current central spindle of the spring generally comprises flange, stepped cylindrical and cylindrical mandrel, right on the outside of the head of cylindrical mandrel
Title is provided with a pair of radial direction jump-ring slots, and the middle part of cylindrical mandrel is axially arranged straight trough.But the central spindle of the spring of this structure is filled
Spring is related to rear cylindrical mandrel's outer circumferential edge beam, easily causes spring breakage.
Utility model content
The purpose of this utility model is to prevent spring from interfering there is provided one kind for the above-mentioned not enough and defect of prior art
Band flat spring mandrel, to solve the above problems.
The technical problem that the utility model is solved can be realized using following technical scheme：
Band flat spring mandrel, including flange and the stepped cylindrical being co-axially located in the flange first end face, its feature
It is, the first end face of the stepped cylindrical is provided with the flat type mandrel in flat circle of position shape, and the flat type mandrel includes it
In a pair relative sides be in outer convex arc surface class cuboid mandrel, symmetrically set on the outside of the head of the class cuboid mandrel
A pair of radial direction jump-ring slots are equipped with, have straight trough the middle part of the class cuboid mandrel is axially arranged.
As a result of technical scheme as above, the utility model is rational in infrastructure, and traditional cylindrical mandrel is set into it
In a pair relative sides be in outer convex arc surface class cuboid mandrel, can make to install that interference fracture is occurred without after spring is existing
As structure is safe and reliable, it is to avoid spring breakage.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of embodiment of the utility model.
Fig. 2 is a kind of using renderings of embodiment of the utility model.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
The utility model is expanded on further in face.
Band flat spring mandrel shown in Figure 1, including flange 100 and be co-axially located in the first end face of flange 100
Stepped cylindrical 200.The first end face of stepped cylindrical 200 is provided with the flat type mandrel 300 in flat circle of position shape, flat type mandrel
300 include the class cuboid mandrel 310 that the relative side of one pair of which is in outer convex arc surface 311, in class cuboid mandrel 310
A pair of radial direction jump-ring slots 312 are symmetrically arranged with the outside of head, have straight trough 313 the middle part of class cuboid mandrel 312 is axially arranged.
With reference to shown in Fig. 2, after the utility model is assembled with spring 400, the inner ring 410 of spring 400 and outer convex arc surface 311
Coordinate, and the inner ring 410 of spring 400 has reserved one with the side at the switching of hook pin 420 with outer convex arc surface 311 and avoided interference with
Avoidance region a, can make to install interference phenomenon of rupture is occurred without after spring 400, structure is safe and reliable, it is to avoid spring breaks
Split.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
