Abstract
An anti-loosening device for a tension bolt of a liquid pump relates to a tension bolt anti-loosening device. A tension seat is provided with a tension bolt which is provided with a nut, an anti-loosening washer is arranged between the nut and the tension seat, a washer locking plate is disposed at one side of the anti-loosening washer and is cooperated with the tension seat to prevent the rotation of the anti-loosening washer; a nut locking plate is equipped at the other side of the anti-loosening washer, and are attached to the side surfaces of the nut, to prevent the nut rotation; when the pump operates for a long time or under poor operating conditions, the anti-loosening washer will not fail to function and the tension bolt will not loose, which prevents the leakage of the pump and avoids influencing the normal work, and the device is suitable for preventing the loosening of the bolt.
Description
Technical field
The present invention relates to the turnbuckle locking device, a kind of specifically liquid pump turnbuckle locking device.
Background technique
We know, existing liquid pump turnbuckle locking device is to be provided with turnbuckle on the tension seat, and turnbuckle is provided with nut, is provided with spring washer between nut and the tension seat, utilizes the elastic force of spring washer to prevent nut loosening.This liquid pump turnbuckle locking device owing to be provided with spring washer between nut and the tension seat, utilizes the elastic force of spring washer to prevent nut loosening, pump works long hours or operating mode when abominable, and spring washer easily lost efficacy, and turnbuckle is loosening, revealing appears in the pump housing, influences proper functioning.
Summary of the invention
The technical problem that the present invention solves is, solve that pump works long hours or operating mode when abominable, spring washer easily lost efficacy, and turnbuckle is loosening, and revealing appears in the pump housing, influence the problem of proper functioning, provide a kind of pump to work long hours or operating mode when abominable, lock washer did not lose efficacy, and turnbuckle is loosening, prevent that revealing from appearring in the pump housing, avoid influencing the liquid pump turnbuckle locking device of proper functioning.
Technological scheme of the present invention is, the tension seat is provided with turnbuckle, turnbuckle is provided with nut, is provided with lock washer between nut and the tension seat, and the main structure characteristics are, lock washer one side is provided with the packing ring locking plate, the packing ring locking plate cooperates with the tension seat, prevents that lock washer from rotating, and the lock washer opposite side is provided with the nut locking plate, fitting in nut locking plate and nut side, prevents that nut from rotating.
The invention has the beneficial effects as follows, because lock washer one side is provided with the packing ring locking plate, the packing ring locking plate cooperates with the tension seat, prevents that lock washer from rotating, the lock washer opposite side is provided with the nut locking plate, fitting in nut locking plate and nut side, prevents that nut from rotating, and pump works long hours or operating mode when abominable, lock washer did not lose efficacy, turnbuckle is not loosening, prevents that revealing from appearring in the pump housing, avoids influencing proper functioning.The present invention is applicable to and prevents bolt looseness.
Description of drawings
Fig. 1, Fig. 2, Fig. 3 are a kind of structural representations of the present invention, also are a kind of embodiment's schematic representation, and Fig. 1 is a plan view of the present invention, and the structural representation of lock washer of the present invention during Fig. 2, Fig. 3 are the plan views of Fig. 1.
Embodiment
Liquid pump turnbuckle locking device as shown in the figure, tension seat 3 is provided with turnbuckle 4, turnbuckle 4 is provided with nut 1, be provided with lock washer 2 between nut 1 and the tension seat 3, lock washer 2 one sides are provided with packing ring locking plate 5, and packing ring locking plate 5 cooperates with tension seat 3, prevent that lock washer 2 from rotating, lock washer 2 opposite sides are provided with nut locking plate 6, and nut locking plate 6 is fitted with nut 1 side, prevent that nut 1 from rotating.As can be seen from the figure, when not using, lock washer 2, packing ring locking plate 5 and nut locking plate 6 are at grade, during use, packing ring locking plate 5 is stuck on the tension seat 3, prevents that lock washer 2 from rotating, with instrument with nut locking plate 6 cocked being fitted on nut 1 side, prevent that nut 1 from rotating, anti-loosing effect is good, and no matter pump works long hours still is that operating mode is abominable, lock washer 2 can not lose efficacy, turnbuckle 4 is not loosening, prevents that revealing from appearring in the pump housing, avoids influencing proper functioning.
