Abstract

The utility model discloses a stereo washer, which is characterized in that the stereo washer comprises a gasket and a periphery. The inner hole of the gasket is bigger than the outer diameter of a connected screw bolt or a screw column, the height of the periphery is higher than the thickness of a connected screw nut, and the minimum gap between the inner wall of the stereo washer and the connected screw nut is smaller than the wall thickness of a commonly used sleeve cylinder. When the connection is conducted, the gasket of the stereo washer still plays the action of a faced washer, and the periphery of the stereo washer wraps the circumference of the screw nut. When an ordinary spanner and sleeve cylinder are used, a stereo gasket can not be inserted, the connection of the screw bolt and the screw column can not be dismounted, and the connection device has the dismounting-proof performance.

Description

A kind of Stereo washer

The utility model relates to a kind of Stereo washer.

Packing ring commonly used at present adopts faced washer; in nut, double-screw bolt connect; between nut and coupled, add a faced washer; do not weighed wounded to enlarge lifting surface area and to protect coupled; but such coupling arrangement is disassembled easily; in the coupling arrangement of fence that needs strict protection or segregator barriers, use plain washer just can't satisfy this special anti-dismounting requirement, work brings difficulty to management maintenance.

Goal of the invention of the present utility model is to propose a kind of bolt, double-screw bolt of making to connect the Stereo washer with anti-dismounting property.

The Stereo washer that the utility model proposes, it is characterized in that Stereo washer comprises pad and peripheral two-part, boring ratio is connected in the pad bolt or double-screw bolt external diameter are big, the peripheral thickness that highly is higher than the attaching nut of institute, the minimum clearance between the inwall of Stereo washer and the attaching nut of institute is less than the wall thickness of use-em-up fitted socket.

Stereo washer can with the supporting use of socket wrench specially adapted for it, the peripheral internal diameter of Stereo washer is bigger than the external diameter of socket wrench specially adapted for it, the periphery can make cylindrical body or other multiple shape.

Owing to the utility model proposes Stereo washer, it is characterized in that Stereo washer comprises pad and peripheral two-part, when implementing to connect, the pad of Stereo washer still plays faced washer, the periphery of Stereo washer encases around the nut, and the minimum clearance between the inwall of Stereo washer and the attaching nut of institute is less than the wall thickness of use-em-up fitted socket, use general wrench like this, sleeve can not insert Stereo washer, just can not demounting bolt, double-screw bolt connects, make coupling arrangement have anti-dismounting property, have only the socket wrench specially adapted for it of use just can enter Stereo washer, nut is screwed out, dismantle this connection.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is the utility model embodiment's user mode figure.

With reference to Fig. 1, Fig. 2, a kind of Stereo washer 1 that the utility model embodiment proposes, Stereo washer 1 is placed nut 2 and coupled 3, between 4, bolt 5 passes coupled and nut 2 connections, because Stereo washer 1 comprises pad 1a and peripheral 1b two-part, pad 1a internal diameter is bigger slightly than bolt 5 external diameters, highly a little higher than nut 2 thickness of peripheral 1b, when implementing to connect, the pad part of Stereo washer still plays faced washer, the periphery of Stereo washer encases around the nut, uses general spanner, sleeve can not insert Stereo washer, just can not demounting bolt, double-screw bolt connects, such coupling arrangement just has anti-dismounting property, have only the socket wrench specially adapted for it of use just can enter Stereo washer, nut is screwed out, dismantle this connection.

Claims
