Description
Technical field
The utility model is related to technical field of fastening, especially rack bolt.
Background technology
Rack bolt is a kind of common bolt, is usually used in being assemblied in bolt sphere, this kind of common bolt is without anti-untwisting
Structure, there are the possibility of loosening, have buried some potential safety problems, therefore, it is necessary to be improved to eliminate the safety to bolt
Hidden danger.
Utility model content
The utility model is directed to deficiency of the prior art, provides rack bolt, by setting anti-loose structure, passes through
Anti-loose structure is held out against with bolt collar cooperation, so as to play locking effect, is eliminated safe hidden trouble.
In order to solve the above technical problems, the utility model is addressed by following technical proposals：Rack bolt, including one
Body formed bolt head and screw rod offers antiratchetting groove on the screw rod, and anti-loose structure is provided in the antiratchetting groove, described anti-
Loose slot includes the No.1 groove body, No. two groove bodies and No. three groove bodies that are sequentially communicated, and fixed block is provided on the No.1 groove body inner wall,
Limiting slot is offered on the fixed block, the anti-loose structure includes limited block, No.1 connecting rod, No. two connecting rods and rubber ball,
The limited block is arranged on the No.1 connecting rod and is interference fitted with the limiting slot, the No.1 connecting rod and No. two companies
Bar is rotatablely connected, and the rubber ball is connected with No. two connecting rods.
The beneficial effects of the utility model are：The utility model passes through anti-loose structure and bolt by setting anti-loose structure
Sleeve cooperation is held out against, and so as to play locking effect, is eliminated safe hidden trouble.
Description of the drawings
Fig. 1 is utility model diagram.
Fig. 2 is the utility model schematic cross-section.
Fig. 3 is the enlarged diagram at D in Fig. 2.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1-Fig. 3, net
Frame bolt including integrally formed bolt head 1 and screw rod 2, offers antiratchetting groove, is set in the antiratchetting groove on the screw rod 2
There is anti-loose structure, the antiratchetting groove includes 31, No. two groove bodies 32 of No.1 groove body being sequentially communicated and No. three groove bodies 33, the No.1
Fixed block 4 is provided on 31 inner wall of groove body, limiting slot 41 is offered on the fixed block 4, the anti-loose structure includes limited block
51st, 52, No. two connecting rods 53 of No.1 connecting rod and rubber ball 54, the limited block 51 be arranged on the No.1 connecting rod 52 and with institute
It states limiting slot 41 to be interference fitted, the No.1 connecting rod 52 and No. two connecting rods 53 are rotatablely connected, the rubber ball 54 and institute
No. two connecting rods 53 are stated to be connected.
During installation, first bolt collar and bolt are coordinated, afterwards, anti-loose structure is moved down so that rubber ball squeezes
Enter between bolt collar and No. three groove bodies, because rubber rounded portion is located at outside No. three groove bodies, therefore, be squeezed into bolt collar
Afterwards so that being fitted closely between bolt collar and bolt, the locking effect of retaining is played, is rotated further by No.1 connecting rod afterwards, entirely
No.1 connecting rod is entered in No.1 groove body, and the mode by being interference fitted between limited block and limiting slot is entire locking
Structure positioning.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to foregoing reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or carry out equivalent substitution to which part technical characteristic；And these
Modification is replaced, and the essence of appropriate technical solution is not made to depart from the spirit and model of various embodiments of the utility model technical solution
It encloses.
