Abstract

The utility model discloses a lock bolt, which comprises a bolt (1). The thread section of the bolt (1) is provided with a straight slot (2) along the parallel axes direction; a key (3) is inserted in the straight slot (2); the bolt (1) is matched with a nut (4); the internal thread of the nut (4) is provided with a key slot (5) along the parallel axes direction; and the cross section shape and the width dimension of the key slot (5) are the same as those of the straight slot (2) on the bolt (1). In the utility model, the straight slot is processed by using an electrode on the thread section of the bolt, and the key is inserted into the straight slot, and the bolt and the nut are positioned and matched to generate the anti-rotation action by utilizing the anti-rotation action of the key to achieve the anti-rotation function. The utility model has the advantages of reliable rotation prevention, high strength, light weight, low requirement on thermal treatment, simple structure, easy manufacture, low production cost and the like.

Description

A kind of chek bolt
Technical field
The utility model relates to a kind of chek bolt, belongs to technical field of fastening.
Background technique
At present, bolt of the prior art is used in general occasion and can satisfies usage requirement substantially.But for vibrating bigger occasion, not only need fine anastomosis, but also need extremely strong antihunt action, otherwise will cause bolt looseness, can't satisfy usage requirement.Though and chek bolts more of the prior art have certain anti-loosening function, exist complex structure, making trouble, high the determining of cost of production, so its using effect still is not ideal enough.
Summary of the invention
The purpose of this utility model be to provide a kind of locking reliably, not fragile, intensity better and simple in structure, make easily, chek bolt that cost of production is lower, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: a kind of chek bolt of the present utility model comprises existing bolt arrangement, and the direction that parallels to the axis on the thread section edge of bolt is provided with straight trough, is inserted with key in straight trough.
Thread section at above-mentioned bolt is provided with 1~3 straight trough that is parallel to each other along the direction that parallels to the axis.
The height of above-mentioned key is not more than the vertical height of straight trough bottom surface to the bolt thread crown, and is not less than the vertical height of straight trough 2 bottom surfaces to bolt 1 thread root.
Be furnished with nut on above-mentioned bolt, and the direction that parallels to the axis in the internal thread upper edge of nut is provided with keyway, the sectional shape of keyway and width dimensions are identical with straight trough on the bolt.
Owing to adopted technique scheme, the utility model is processed straight trough with electrode on the thread section of bolt, and inserts key in straight trough, utilizes the rotation inhibiting effect of key, the bolts and nuts location is cooperated produce the anti-rotation effect, reaches the function of anti-rotation.Advantages such as therefore, the utility model is compared with existing bolt, and it is reliable to the utlity model has anti-rotation, and intensity is good, and is in light weight, simple in structure to heat treated less demanding, makes easily, and cost of production is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation when being furnished with nut on the bolt of the present utility model.
Being labeled as in the accompanying drawing: 1-bolt, 2-straight trough, 3-key, 4-nut, 5-keyway, the height of h-key.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: when making chek bolt of the present utility model, its bolt 1 can adopt steel to make according to a conventional method, during making, thread section at bolt 1 is produced 1~3 straight trough that is parallel to each other 2 along the direction that parallels to the axis, the sectional shape of straight trough 2 is made into rectangle, and at least 1 straight trough 2, plugs key 3; The height h of key 3 is controlled at is not more than the vertical height of straight trough 2 bottom surfaces, and be not less than the vertical height of straight trough 2 bottom surfaces to bolt 1 thread root to bolt 1 screw thread crown; Simultaneously on bolt 1, be furnished with nut 4, and the direction that parallels to the axis in the internal thread upper edge of nut 4 produces keyway 5, the sectional shape and the width dimensions of keyway 5 all is made into identical with straight trough 2 on the bolt 1.
