Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by persons skilled in the art based on the embodiments in the present application without any creative work belong to the protection scope of the present application.

As shown in fig. 1-5, the present application provides a technical solution: the utility model provides a nested formula spring for automobile starter, includes innerspring 1, external spring 2, roof 3 and bottom plate 4, innerspring 1's outside nestification has external spring 2, through two springs of innerspring 1 and external spring 2, has formed nested structure, roof 3 has been installed at innerspring 1 and external spring 2's top, innerspring 1 and external spring 2's bottom is fixed with bottom plate 4, utilize roof 3 and bottom plate 4, can fix innerspring 1 and external spring 2.

Further, the edge position welding of roof 3 bottom has external sleeve 31, and the bottom surface of roof 3 is fixed with rubber pad 32, and round hole 33 has been seted up to the intermediate position of rubber pad 32, and the external sleeve 31 of setting can be used with built-in sleeve 41 mutually supporting, is convenient for form a protecting sheathing.

Further, the rubber pad 32 is of an annular structure, the outer diameter of the rubber pad 32 is the same as the diameter of the inner wall of the external sleeve 31, and the rubber pad 32 can be conveniently arranged inside the external sleeve 31 by matching the size of the rubber pad 32 with the size of the external sleeve 31.

Further, the inside of round hole 33 crosses built-in spring 1 and external spring 2, and the link at built-in spring 1 and external spring 2 top all welds in the bottom of roof 3, and the round hole 33 of setting makes built-in spring 1 and external spring 2 be connected with roof 3 that can be fine.

Further, an inner sleeve 41 is welded at the edge position of the top of the bottom plate 4, an annular edge block 42 is welded at the top end of the inner sleeve 41, the inner end of the inner sleeve 41 can be fixed inside the outer sleeve 31 through the annular edge block 42, and the inner end of the inner sleeve 41 is not easy to slide out due to blocking of the annular edge block 42.

Further, built-in sleeve 41 and external sleeve 31 constitute protecting sheathing jointly, and built-in sleeve 41's annular limit piece 42 inlay card is in the inside of external sleeve 31 to protecting sheathing is extending structure, through protecting sheathing's effect, has played fine guard action to nested formula spring structure, also makes the spring structure difficult rusty.

Further, the outer ring diameter of the ring-shaped edge block 42 is smaller than the outer ring diameter of the rubber pad 32, and the inner ring diameter of the ring-shaped edge block 42 is larger than the inner ring diameter of the rubber pad 32, so that the ring-shaped edge block 42 can be well extruded on the surface of the rubber pad 32 when the built-in spring 1 and the external spring 2 are contracted.

Further, bottom plate 4, roof 3, external spring 2 and built-in spring 1 constitute nested spring structure jointly, and the size of bottom plate 4 is the same with roof 3's size, through nested spring structure, can increase the elasticity of spring itself.

The working principle is as follows: before using the nested spring for the automobile starter, the whole nested spring for the automobile starter needs to be simply understood in structure, firstly, when the inner spring 1 and the outer spring 2 contract, the distance between the top plate 3 and the bottom plate 4 is shortened, at this time, the outer sleeve 31 moves down along with the deformation of the inner spring 1 and the outer spring 2 and covers the outer part of the inner sleeve 41 until the inner spring 1 and the outer spring 2 contract to the maximum deformation amount, and the annular side block 42 of the inner sleeve 41 presses on the rubber pad 32, then, when the contracted inner spring 1 and the outer spring 2 recover to a long time, the distance between the top plate 3 and the bottom plate 4 is increased, at this time, the outer sleeve 31 moves up along with the deformation of the inner spring 1 and the outer spring 2, and the inner sleeve 41 gradually appears from the inner part of the outer spring 2, until the inner spring 1 and the outer spring 2 recover to their original lengths.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
