Abstract
The utility model relates to an anti-loosening stop washer, which comprises a washer body, a through hole, one long wing sheet and two short wing sheets on the outer edge of the washer body. The connecting position of each wing sheet and the outer edge of the washer body is provided with two concave arcs. When the anti-loosening stop washer is used and installed, the washer body is first sheathed on a bolt, and then, a nut is arranged and screwed. The wing sheets are adjusted and bent, and the two short wing sheets are tightly clung to two side surfaces of the nut, and the long wing sheet is tightly clung to one side surface of a member. When the looseness of the bolt and the nut possibly occurs due to the action of vibration outside force, the wing sheets which can be bent produce reaction force to prevent the looseness which possibly occurs due to the fact that the wing sheets have high rigidity. The purpose of the utility model is to provide the anti-loosening stop washer which is simple and practical, and is particularly reliable.
Description
Technical field
The utility model relates to fastening and fixed component, the locking lock washer of locking lock washer that particularly a kind of railway operation system that is suitable for, especially contact nets in electrified railways are used.
Background technique
At present be fastenedly connected basic employing bolt width of cloth Placement between the element of installation, belong to the locking mode of friction, its variable-tooth type nut that often uses, contour double nut, spring washer, full-metallic inserts nut, nylon inserts nut etc., nut loosening and even obscission then appear in the very big railway operation system of continuous shaking and ocsillator strenght that applies to, very serious, not only difficult in maintenance, the parts loss is big, reduces the reliable appropriateness of contact net safe operation especially greatly.
The model utility content
The purpose of this utility model provides a kind of locking stop, safe and reliable locking lock washer.
The locking lock washer of the utility model comprises circle body, wherein on the circle body axis of pitch 1 bent short limb sheet is arranged each side, and the side on the longitudinal axis of circle body has 1 bent long fin.
The locking lock washer of the utility model, all there is concave arc the both sides of wherein said bent fin and circle body outer rim junction, and the concave arc radius is 1.25mm.
The locking lock washer of the utility model, wherein said circle body and bent fin adopt Austenitic Stainless Steel to make.
The locking lock washer of the utility model, wherein said bent fin thickness is 1～3mm.
Circular diameter is 10.5mm in the locking lock washer of the utility model, wherein said circle body, and outside diameter is 15.5mm; Long fin is long to be 14.75mm, and wide is 8mm; The short limb length of a film is 12.25mm, and wide also is 8mm.
Circular diameter is 12.5mm in the locking lock washer of the utility model, wherein said circle body, and outside diameter is 17.5mm; Long fin is long to be 15.75mm, and wide is 8mm; The short limb length of a film is 16.5mm, and wide also is 8mm.
The locking lock washer of the utility model has following advantage than existing locking stop technology:
1. adopt this locking lock washer to realize the locking Placement of new mechanical, be that member and bolt pair are linked to be a fastener by this locking lock washer, the opposite force that utilizes the fin clamp structure of lock washer to be produced stops the rotation of circling round of nut, the bolt tightened, this is a kind of simple, practical technical measures, guarantees permanent locking stop.This locking stop gas ket is simple in structure, with low cost, easy for installation, and is prolonged and usefulness is beneficial to and promotes the use of.
2. this locking lock washer with the host material of Austenitic Stainless Steel as packing ring, has embodied the practicability of design.Like this, characteristics such as this locking card washer impacts with regard to having corrosion protection, not yielding, good toughness, intensity height are specially adapted to the railway traffic system and relatively use in the bad working environment.
Below in conjunction with accompanying drawing this locking lock washer is described further.
