Abstract
The utility model discloses a lock washer for multiple bolts. The lock washer comprises a lock blade (1); through holes (3) with the number corresponding to that of the bolts (2) are formed on the lock blade (1); and turned-over edges (4) are formed at the margins of the through holes (3). One lock washer can lock two or more than two nuts at the same time, and cannot fall off when one nut is separated from the bolt. The lock washer has the advantages of good locking effect, high reliability and convenient assembly.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly relates to a kind of many bolts lock washer.
Background technique
Bolt, nut are the most frequently used coupling and fastening pieces, and be loosening for preventing fastening piece, and commonly used have modes such as double nut, cotter pin, adopts self-locking nut to prevent to become flexible in addition.Also have in actual applications and use the monolock sheet to prevent single nut loosening.But high especially or owing to be subjected to the special occasions that spatial constraints is not easy to install at some to reliability requirement, adopt existing double nut, cotter pin or monolock sheet just special trouble in installation and maintenance.Such as in airplane engine,, install very inconvenient because the spatial position is especially little, also have airplane engine very strict to the requirement of reliability, if nut takes place, things such as pad fall into motor, will break the gas compressor of high speed rotating etc., cause serious accident.
The model utility content
The purpose of this utility model is, a kind of many bolts lock washer is provided.It adopts simple structure, and an available pad pins two or more nuts simultaneously, prevents that nut loosening is effective, and the reliability height is specially adapted to the occasion that some have specific (special) requirements.
The technical solution of the utility model: a kind of many bolts lock washer, comprise locking plate, locking plate is provided with and the corresponding through hole of bolt quantity and position, and the edge of through hole is provided with flange.
In above-mentioned many bolts lock washer, described locking plate is that the thin plate of rectangle, arc, triangle, polygonal or star is made.
In aforementioned many bolts lock washer, described thin plate is the carbon steel steel plate, and its thickness is 0.5～2mm.
Compared with prior art, the utility model can pin two or more nuts simultaneously with a pad, and when the nut on the bolt came off, pad can not come off.Locking effect is good, and the reliability height is installed also very convenient.

Being labeled as in the accompanying drawing: 1-locking plate, 2-bolt, 3-through hole, 4-flange, 5-nut.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment.Fig. 1 is a structural representation of the present utility model, and the utility model comprises locking plate 1, and locking plate 1 is made for the thin plate of rectangle, arc, triangle, polygonal or star.Described thin plate is the carbon steel steel plate, and its thickness is 0.5～2mm.Locking plate 1 is provided with the through hole 3 corresponding with bolt 2 quantity, and the edge of through hole 3 is provided with flange 4.As shown in Figure 1, flange and locking plate are same plane before nut is fixing; As shown in Figure 2, flange 4 became an angle of 90 degrees with locking plate after flange 4 was dug.During installation, pad of the present utility model is mounted on the bolt 2 as shown in Figure 3, and nut 5 is screwed on the bolt 2 and fixes tight.After fixing tightly, as shown in Figure 4, flange 4 is dug on nut 5 by special tool.Pad of the present utility model in actual applications also can be rectangle or other shape, is the triangle pad as shown in Figure 5, and it can pin three nuts on the bolt simultaneously.According to principle of the present utility model, also can make the pad that can pin the bolt upper cap nut more than three simultaneously.So long as adopt structure of the present utility model, all belong to protection domain of the present utility model.
