Abstract
The utility model provides a quick-acting bushing capable of preventing a quick-acting plate from axially drifting, and the whole quick-acting bushing is a circular ring body comprising two parts, namely an upper part and a lower part. Fins are additionally arranged on both sides between the two parts respectively; one side surface of the quick-acting plate sleeved in the upper part is attached to the fins to limit the axial position of the quick-acting plate, so that scratching between the quick-acting plate and the side surface of a contact base can be avoided, the rotation resistance of the quick-acting plate is reduced, and the potential hazard of contact base blockage is eliminated.
Description
Technical field
The utility model relates to a kind of switch machine inner member, especially relates to a kind of quick-action lining that prevents the quick-acting slice axial float.
Background technique
The quick-action lining is a vital part in the ZD6 switch machine, and its integral body is a cirque body, divides upper and lower two parts; Top overcoat quick-acting slice, each is pruned one the both sides of bottom, so that embed in the corresponding groove of contact seat; Confirm the position of quick-action lining, make it and to rotate.Though existing quick-action bush structure can play the positioning action of quick-acting slice, can only guarantee the centering of quick-acting slice, and not possess the axially locating of quick-acting slice that promptly quick-acting slice can produce axial float in the course of the work.The adverse consequences that this structure caused makes exactly and has caused quick-acting slice its end face and contact seat contacts side surfaces in the course of the work 1, increased the resistance in the quick-acting slice rotary course; 2, quick-acting slice can be with the scratch of contact seat side, and then the rotational resistance of quick-acting slice can strengthen, and this is one of reason that causes the contact seat jam.
Summary of the invention
The problem that the utility model will solve provides a kind of quick-action lining that prevents the quick-acting slice axial float.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of quick-action lining that prevents the quick-acting slice axial float; Integral body is cirque body, divides upper and lower two-part, caves in toric both sides, bottom; It is characterized in that the both sides between two-part also respectively are provided with the wing of an evagination up and down.
Further, the thickness of said wing is 0.5mm.
Further, cirque body top external diameter is 58mm.
Further, spacing is 48mm between the bi-side of caving in, said cirque body bottom.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; In the assembling; The side of quick-acting slice and two wings are fitted, and have limited the axial position of quick-acting slice, and this has just been avoided the scratch of quick-acting slice and contact seat side; Reduce the quick-acting slice rotational resistance, eliminated a hidden danger of contact seat jam.

Embodiment
As shown in Figure 2; The quick-action lining integral body of the utility model is cirque body, can be the cylindrical body of no axle center hole also, is divided into two parts up and down; Top 1 external diameter a is 58mm; The spacing b of two sides caving in the bottom is 48mm, and the both sides between upper and lower two-part also respectively are provided with a wing 3, and the thickness of this wing is 0.5mm.
In the proper functioning, 48mm wide side in bottom embeds in the groove of contact seat respective widths, confirms the position of quick-action lining, makes it and can not rotate; Overlapping a quick-acting slice that onesize circular hole is arranged on the outer surface on top; A side of quick-acting slice is fitted on the wing of both sides; Limited the axial position of quick-acting slice; The scratch that this has just been avoided quick-acting slice and contact seat side has reduced the quick-acting slice rotational resistance, has eliminated a hidden danger of contact seat jam.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (4)
