Disclosure of Invention

The utility model discloses the technical problem that will solve lies in: the utility model provides a positioning bolt, it has been solved at present when the not hard up condition appears in the bolt, overhauls the workman and utilizes tools such as spanner to screw up positioning bolt's mode next and cause the extension of maintenance time to cause the problem that maintenance efficiency reduces.

The utility model discloses the technical problem that will solve takes following technical scheme to realize:

A positioning bolt comprises a bolt body, wherein the bolt body comprises a bolt head, a screw rod and a polished rod, the bolt body also comprises a bolt connecting part and a bolt sealing gasket matched with the bottom of the bolt connecting part, the bolt connecting part comprises a plurality of connecting blocks, each connecting block comprises a vertical end, a horizontal end and an arc-shaped end, the vertical ends of the connecting blocks are fixedly connected together, the bottom of the screw is fixedly connected with the joint of one end of the vertical end of the connecting blocks, the bottom of the horizontal end of each connecting block is fixedly connected with a limiting block, the bolt sealing gasket is fixedly connected with a plurality of limiting blocks, one end of the limiting blocks or one end of the horizontal end of the connecting block are fixedly connected together, the top of the screw rod is fixedly connected with the joints of the limit blocks, and the top of the polish rod is fixedly connected with the bottom of the screw rod.

As a preferred example, the bolt sealing gasket is in a bowl shape, a limiting groove matched with the limiting blocks is formed in the bowl opening end of the bolt sealing gasket, and the bolt sealing gasket is sleeved on the screw rod in a threaded manner.

As a preferable example, the number of the plurality of limiting grooves, the plurality of limiting blocks and the plurality of connecting blocks is at least four.

As a preferable example, the length of the horizontal end of the connecting block is greater than that of the limiting block.

As a preferred example, the vertical end, the horizontal end and the arc end of the connecting block are integrally formed.

The utility model has the advantages that: the utility model discloses a bolted connection portion, stopper, bolted sealing pad, spacing groove, mainly be by the stopper card on the bolted sealing pad spacing inslot on every connecting block in the bolted connection portion to utilize the length difference between every connecting block bottom and the stopper, and combine the sign line of doing on the required fixed article, judge whether the bolt body is in the state of screwing up, thereby replace the mode that overhauls the workman and overhauls the bolt in turn, thereby improved maintenance efficiency.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of the bolt gasket of the present invention;

Fig. 3 is a schematic structural view of a portion a in fig. 1.

In the figure: the bolt comprises a bolt head 1, a screw rod 2, a polished rod 3, a bolt connecting part 4, a bolt sealing gasket 5, a limiting block 6 and a limiting groove 7.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-3, a positioning bolt comprises a bolt body, the bolt body comprises a bolt head 1, a screw rod 2 and a polish rod 3, the bolt body further comprises a bolt connecting part 4 and a bolt sealing gasket 5 matched with the bottom of the bolt connecting part 4, the bolt connecting part 4 comprises a plurality of connecting blocks, and each connecting block comprises a vertical end, a horizontal end and an arc-shaped end, the vertical ends of the connecting blocks are fixedly connected together, and the bottom of screw rod 2 and the vertical end one end junction fixed connection of a plurality of connecting blocks, the equal fixedly connected with stopper 6 in horizontal end bottom of every connecting block, the bolt sealing pad 5 and the 6 fixed connection of a plurality of stoppers, the equal common fixed connection of one end of the one end of a plurality of stoppers 6 or the one end of a plurality of connecting block horizontal ends, the top and the 6 junction fixed connection of a plurality of stoppers of screw rod 2, the top of polished rod 3 and the bottom fixed connection of screw rod 2.

The bolt sealing gasket 5 is in a bowl shape, a limiting groove 7 matched with the limiting blocks 6 is formed in the bowl opening end of the bolt sealing gasket 5, and the bolt sealing gasket 5 is sleeved on the screw rod 2 in a threaded mode.

the number of the limiting grooves 7, the limiting blocks 6 and the connecting blocks is at least four.

the length of the horizontal end of the connecting block is larger than that of the limiting block 6.

The vertical end, the horizontal end and the arc end of the connecting block are integrally formed.

Before the bolt body is rotated into the threaded hole for fixing the object, a plurality of mark lines are arranged on the surface of the threaded hole for fixing the object, the positions of the mark lines are respectively consistent with the horizontal ends of a plurality of connecting blocks, when the bolt body is screwed into the threaded hole and the bolt body is in a screwed state in the threaded hole, one of the connecting blocks is marked with red, the mark line corresponding to the connecting block is also marked with red, when one of the red marked connecting blocks is aligned with the red marked line, the bolt is in the screwed state, otherwise, the bolt is loosened and needs to be screwed in time.
