Description
Technical field
The utility model is related to technical field of fastening, especially plum-blossom flange bolt.
Background technology
Plum-blossom flange bolt is a kind of common bolt, when in use, because misoperation or the size of cooperating equipment with
The size of bolt head is not inconsistent, and causes bolt head abrasion deformation, ultimately result in bolt can not normal mounting scrap or install it
After can not take out, therefore, need to design certain structure in face of this kind of problem to solve.
Utility model content
The utility model is directed to deficiency of the prior art, plum-blossom flange bolt is provided, by being set on bolt head
Position limiting structure is put, the operable region of limitation bolt head, all abrasion becomes so as to make entire bolt head in misoperation
Shape provides fault tolerant workspace, extends bolt service life.
In order to solve the above technical problems, the utility model is addressed by following technical proposals：Plum-blossom flange bolt, bag
Integrally formed bolt head and screw rod are included, several groups of groove groups are symmetrically offered on the bolt head, groove group is equal described in every group
Including several grooves, position limiting structure is both provided in two grooves of the top；
The position limiting structure includes locating piece and limited block, and the locating piece includes clamping block, circular connection sheet and film
Bag, the clamping block and the circular connection sheet are connected, and the film bag is arranged in the circular connection sheet, while
Glue is filled in the film bag, several article putting grooves for being used to place the locating piece are offered on the limited block, simultaneously
It is offered on the limited block side wall for coordinating the buckling groove for being clamped the locating piece, wherein, the buckling groove includes vertical
To No.1 groove body, No. two horizontal groove bodies and No. three groove bodies with the circular connection sheet cooperation, the No.1 groove body, institute
It states No. two groove bodies and No. three groove bodies is sequentially communicated.
The beneficial effects of the utility model are：The utility model limits bolt by setting position limiting structure on bolt head
Operable region so as to make entire bolt head whole abrasion deformation in misoperation, provides fault tolerant workspace, extends
Bolt service life.
Description of the drawings
Fig. 1 is utility model diagram.
Fig. 2 is the schematic cross-section of the utility model bolt head.
Fig. 3 is the enlarged diagram at D in Fig. 2.
Fig. 4 is the schematic top plan view of the utility model locating piece.
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. 4, plum
Flower flange bolt, including integrally formed bolt head 1 and screw rod 2, symmetrically offers several groups of groove groups on the bolt head 1,
Groove group described in every group includes several grooves 11, and position limiting structure is both provided in two grooves 11 of the top.
The position limiting structure includes locating piece and limited block 3, and the locating piece includes clamping block 41,42 and of circular connection sheet
Film bag 43, the clamping block 41 and the circular connection sheet 42 are connected, and the film bag 43 is arranged on the circle even
In contact pin 42, while glue is filled in the film bag 43, it is several described fixed for placing to be offered on the limited block 3
The article putting groove 31 of position part, while offered on 3 side wall of limited block for coordinating the buckling groove for being clamped the locating piece,
In, the buckling groove includes the No.1 groove body 32 of longitudinal direction, No. two groove bodies 33 of transverse direction and coordinates with the circular connection sheet 42
No. three groove bodies 34, the No.1 groove body 32, No. two groove bodies 33 and 34 body of No. three slots are sequentially communicated.
Wherein, film bag sets three most preferably, in this way, after film coating racks, the glue of outflow can fix limit
Position block, meanwhile, when needing to remove limited block, and without exerting so that limited block fixes, it is convenient to remove.
When limited block is installed, a locating piece is encased in buckling groove, first by laterally aligned No. two groove bodies of clamping block,
It is entered after passing sequentially through No. three groove bodies, No. two groove bodies in No.1 groove body, then locating piece is rotated by 90 ° so that clamping block and three
Number groove body inner wall abuts against, and locating piece is not fallen out with buckling groove mating connection, then limited block and locating piece is integrally encased in recessed
In slot, after pressing, film coating racks, so that limited block is connected with groove, at this point, can make for instrument after glue outflow
Scope is the region above limited block；When needing to increase using area, the overall structure of limited block and locating piece is extracted,
Old locating piece under dismounting takes out new locating piece out of article putting groove, repeats above-mentioned installation steps.
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.
