Description
Technical field
The utility model is related to machanical fastener technical field more particularly to a kind of pawl gaskets.
Background technology
Bolt or screw assembly are used for the component to play the role of fastening, the object loosening fastened sometimes can generate it is serious after
Fruit loosens as rail connects, derailing etc. can be caused surprisingly to occur, so it is always people's research to prevent that connection component from loosening
Problem.
The reason for nut bolt loosens have it is very much, in the case of sharp pounding, due under alternating load or operating temperature
When higher, the normal pressure on nut rubbing surface reduces or disappears, and frictional force reduction or multiplicating on rubbing surface is made to make along spiral shell
The vibration force of female radial direction promotes nut rotation, causes nut loosening.
To solve the above-mentioned problems, the present inventor is entitled " a kind of dismountable in Application No. 201510469397.3
A kind of locking fastening structure is disclosed in the patent of invention of check bolt or screw assembly ", the applying date of the patent is 2015
On August 4, and being authorized for 19th in September in 2017, but when the present inventor states patent on the implementation, find wherein institute
The pawl gasket used is there are certain design defect, as shown in Figure 1, upper radial on the end face of above-mentioned pawl gasket 10
Several pawls 11 are evenly arranged with, gasket 11 is being provided with several protrusions 12 on the one side by fastener, protrusion
12 with by several corresponding shrinkage pools on fastener end face cooperate that the pawl gasket is prevented to rotate, elastic pawl 11
It is distributed in around pawl gasket 10, and the structure that pawl 11 is integrally formed with pawl gasket 10, the inside of pawl 11 leads to
It crosses connecting portion 13 to be connected with pawl gasket 10, in order to enable there are one suitable open-angles for the end face of pawl 11 and pawl gasket 10
Degree (this opening angle is to carry out retaining in order to which the pawl structures of elastic pawl and bolt bolt cap is made easily to coordinate), connecting portion 13
Size is smaller, which results in the actual use process, due to pawl 11 can repeatedly carry out deformation, after long-time use
Easily fracture in connecting portion 13, be not a reliable structure, it is therefore desirable to develop it is a kind of meet above-mentioned function, connection
The pawl gasket that place is not easily broken.
Utility model content
The purpose of this utility model is that in place of avoiding the deficiencies in the prior art, a kind of pawl gasket is provided, so as to effectively
Solve the shortcomings of the prior art.
To achieve the above object, the technical solution that the utility model is taken is：A kind of pawl gasket, including ring body, ring
The one side of circle body is provided with to prevent the first anti-rotation structure of ring body own rotation, and the opposite side of ring body, which is provided with, to be used for
The second anti-rotation structure for preventing nut or bolt from rotating；Second anti-rotation structure includes multiple along being arranged circumferentially for ring body
Elastic pawl piece, the elastic pawl are the sector structure that punching press bending forms directly on ring body, are corresponded on ring body
The fan groove that sector structure forms closing is stated, elastic pawl is connected by one of straight flange of its sector structure with ring body,
And flanging is formed in junction, another straight flange of elastic pawl and two arc-shaped sides are in vacant state；
The extended line of the flanging is directed toward the center of circle of ring body.
Further, first anti-rotation structure is several anti-rotations protrusion.
The above-mentioned technical proposal of the utility model has the advantages that：The elastic pawl of the utility model and ring body
Connecting portion (i.e. flanging 22) size bigger, be not easily broken, and without architectural limitation, can be increased according to actual conditions
Big or reduction, and stress is more reasonable, and the flanging of the application is set along the radial direction of ring body, and deformation is being generated by pressure
Afterwards, it only can uniformly be moved to the direction close to ring body, not interfere with normal use.
Description of the drawings
Fig. 1 is the structure diagram of pawl gasket in the prior art；
Fig. 2 is the utility model embodiment dimensional structure diagram one；
Fig. 3 is the utility model embodiment dimensional structure diagram two.
Specific embodiment
The embodiment of the utility model is described in further detail with reference to the accompanying drawings and examples.Following embodiment
For illustrating the utility model, but cannot be used for limiting the scope of the utility model.
In the description of the utility model, unless otherwise indicated, " multiple " are meant that two or more；Term
The orientation or position of the instructions such as " on ", " under ", "left", "right", " interior ", " outer ", " front end ", " rear end ", " head ", " afterbody " are closed
Be for based on orientation shown in the drawings or position relationship, be for only for ease of description the utility model and simplify description rather than
Indicate or imply that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore cannot
It is interpreted as the limitation to the utility model., it is necessary to which explanation, provides unless otherwise specific in the description of the utility model
And restriction, term " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected,
Or it is integrally connected；Can be mechanical connection or electrical connection；It can be directly connected, intermediary can also be passed through
It is indirectly connected.For the ordinary skill in the art, it can understand above-mentioned term in the utility model with concrete condition
Concrete meaning.
As Figure 2-3, a kind of pawl gasket described in the present embodiment, including ring body 20, the one side of ring body 20 is set
It is equipped with to prevent the first anti-rotation structure of 20 own rotation of ring body, the opposite side of ring body 20 is provided with to prevent nut
Or the second anti-rotation structure that bolt rotates；Second anti-rotation structure includes the multiple elastic pawl pieces being arranged circumferentially along ring body 20
21, elastic pawl 21 is the sector structure that punching press bending forms directly on ring body 20, and above-mentioned sector is corresponded on ring body 20
Structure forms the fan groove 23 of closing, and elastic pawl 21 is connected by one of straight flange of its sector structure with ring body 20,
And flanging 22 is formed in junction, another straight flange of elastic pawl 21 and two arc-shaped sides are in vacant state；
