Abstract
The utility model discloses a spring sheet for a transmission chain joint. The spring sheet comprises a spring sheet body, wherein the middle of the spring sheet body is provided with a through hole, and the axial direction of the through hole is vertical to the plane of the spring sheet body. The through hole is a waist-shaped hole; and one side of the spring sheet body is disconnected, and the separation line at the disconnected position is on the straight line of the long axis of the waist-shaped hole. Compared with the prior art, the spring sheet has the advantages that: the separation line is vertically expanded by adopting a special spring sheet mounting tool, and the spring sheet is sleeved in a joint pin clamping groove, so that a phenomenon that the spring sheet is separated from the joint is not produced, and the spring sheet is safe, stable and reliable. The quality of a product is improved, and the satisfaction degree of a user is improved.
Description
Technical field
The utility model is the improvement of the spring sheet of drive chain joint, has guaranteed that joint is firm, prevents that the out of stock rear chain of spring sheet from breaking off, causing danger.
Background technique
For the convenience of the user to the mounting or dismounting and the maintenance needs of chain, general drive chain all adopts nipple pin and the assembly adapter piece as closed ring, shown in Figure 1A, 1B and 1C:
Spring sheet opening direction and chain movement are in the opposite direction when 1, installing, otherwise drop easily, produce quality fault;
Even 2 according to after the technical requirements installation; Its reliability is also low; This spring sheet is an open state with nipple pin wherein in chain rapid movement process, and is big through being easy to corner angle after the motion wearing and tearing, in chain repeated use process, breaks away from from opening easily;
Between centers crack, hole is big when 3, installing, and spring sheet produces the skew back distortion, causes chain scratch passage, influences chain running environment.
Summary of the invention
The problem that the utility model will solve is to improve original chip architecture of the spring, its installation back safety and stability is not reliably produced come off, and causes danger.Concrete technological scheme is following:
A kind of drive chain joint is used spring sheet, comprises that the centre of spring sheet body, spring sheet body has through hole, and it is vertical that the axial and spring sheet body of through hole belongs to the plane.Said through hole is a waist shaped hole; One side of said spring sheet body is broken off, and the strapping wires of gap are on the straight line of waist shaped hole major axis place.
The shape of said spring sheet body and the shape of waist shaped hole are similar figures.
The position, center of said spring sheet body has manhole, and this manhole overlaps with the center of said waist shaped hole, and the diameter of manhole is long greater than the minor axis of waist shaped hole.
Compared with prior art, employing special bullet reed setting tool struts the strapping wires place up and down, is inserted in the nipple pin draw-in groove to get final product, and can not produce spring sheet and throw off the nipple pin phenomenon, and safety and stability is reliable.The raising user satisfaction of improving the quality of products.
Description of drawings
Figure 1A be drive chain in the existing technology split ring sheet figure,
Figure 1B be existing technology middle joint assembly installation diagram,
Fig. 2 A be this spring sheet figure,
Fig. 2 B be the utility model assembling finished figure,
Fig. 3 uses the assembling condition schematic representation for spring sheet.
Among the figure, 1 is that nipple pin, 2 is that tab, 3 is that spring sheet, 4 is that strapping wires, 5 are that manhole, x are for the waist shaped hole major axis belongs to straight line, y is that the waist shaped hole minor axis belongs to straight line.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
A kind of drive chain joint is used spring sheet, comprises that the centre of spring sheet body, spring sheet body has through hole, and it is vertical that the axial and spring sheet body of through hole belongs to the plane.Said through hole is a waist shaped hole; One side of said spring sheet body is broken off, and the strapping wires of gap are on the straight line of waist shaped hole major axis place.
The shape of said spring sheet body and the shape of waist shaped hole are similar figures.
The position, center of said spring sheet body has manhole, and this manhole overlaps with the center of said waist shaped hole, and the diameter of manhole is long greater than the minor axis of waist shaped hole.
