Description

Anti-loosening bolt for petroleum pipeline

Technical Field

The utility model relates to a petroleum technology field, concretely relates to locking bolt that moves for petroleum pipeline.

Background

The bolt is a mechanical part and is matched with a cylindrical threaded fastener of a nut. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection.

At present, when petroleum pipelines are connected, bolts are often required to be used for fixedly connecting the pipelines, and when the existing bolts are fixedly connected, the bolts and nuts can be connected loosely due to long-time use and corrosion of petroleum, so that the pipelines are extremely unstable in connection, and petroleum transportation is influenced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is because the erosion of long-time use and oil can lead to the bolt to be connected with the nut not hard up to the connection that leads to the pipeline becomes extremely unstable, influences the transportation of oil, provides a locking bolt that moves for petroleum pipeline, makes its inserted bar, draw-in groove, spring and fixture block isotructure through setting up, can make the inserted bar fix in the draw-in groove, thereby avoids the relative rotation of nut and screw rod, prevents that the bolt is not hard up when using, solves the above-mentioned problem that proposes.

The utility model provides a technical scheme that technical problem adopted is: a locking bolt for a petroleum pipeline, comprising: the cap head, cap head lower extreme fixed connection screw rod, threaded connection nut on the screw rod, screw rod lower extreme grafting fixed plate, the equal fixed connection inserted bar in fixed plate upper end both sides, the inserted bar upper end all with the nut joint, play the spacing fixed effect to the nut, the draw-in groove has all been seted up to the nut both sides, equal sliding connection slide bar in the draw-in groove, the slide bar is close to the equal fixed connection fixture block in one side each other, the slide bar is kept away from the equal fixed connection handle in homonymy fixture block one side, and the handle and the slide bar structure of setting can be convenient for drive the fixture block and remove to make things convenient for the use of fixture block.

As an optimal technical solution of the utility model: the spring is fixedly connected in the clamping groove, one side of the spring is fixedly connected with the clamping block at the same side, the sliding rod penetrates through the spring at the same side, the spring drives the clamping block to restore conveniently, and the clamping block can be clamped in the slot.

As an optimal technical solution of the utility model: the inserting grooves are formed in one side of the upper end of the inserting rod and are matched with the clamping blocks on the same side, so that the clamping blocks can conveniently enter the inserting grooves, and the inserting rod is fixed.

As an optimal technical solution of the utility model: the clamping blocks are all triangular, and the clamping blocks are matched with the clamping grooves on the same side, so that the clamping blocks can conveniently reciprocate in the clamping grooves.

As an optimal technical solution of the utility model: the spout has been seted up to the screw rod lower extreme, the spout is pegged graft to the fixed plate, makes things convenient for fixed plate and screw rod to be connected.

The utility model has the advantages of it is following: through the inserted bar, draw-in groove, spring and fixture block isotructure that set up, can make the inserted bar fix in the draw-in groove to avoid the relative rotation of nut and screw rod, prevent that the bolt is not hard up when using, and the handle and the slide bar structure that set up can conveniently drive the fixture block and remove, thereby make things convenient for the dismantlement of inserted bar, and then when overhauing, make things convenient for the separation of screw rod and nut.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1-3, the present invention provides a technical solution: a locking bolt for a petroleum pipeline comprising: cap 1, at 1 lower extreme fixed connection screw rod 2 of cap, and with nut 3 and 2 threaded connection of screw rod, nut 3 after the convenience is connected is fixed, prevent not hard up, at 2 lower extreme grafting fixed plates 4 of screw rod, and at the equal fixed connection inserted bar 41 of fixed plate 4 upper end both sides, then make the upper end and the 3 joints of nut of two inserted bars 41, draw-in groove 31 has all been seted up in 3 both sides of nut, and equal sliding connection slide bar 6 in two draw-in grooves 31, then make two slide bars 6 be close to the equal fixed connection fixture block 7 in one side each other, for the convenience of movement of fixture block 7, keep away from the equal fixed connection handle 5 in homonymy fixture block 7 one side at two slide bars 6.

Wherein, in the ease that fixture block 7 gets into slot 42, equal fixed connection spring 8 in two draw-in grooves 31, and make one side of two springs 8 all with homonymy fixture block 7 fixed connection, and homonymy slide bar 6 all runs through homonymy spring 8, fix in draw-in groove 31 for the ease that inserted bar 41 is fixed, slot 42 has all been seted up in inserted bar 41 upper end one side, and make two slots 42 all with homonymy fixture block 7 looks adaptation, and all set up two fixture blocks 7 and be triangle-shaped, make fixture block 7 all with homonymy draw-in groove 31 looks adaptation.

Wherein, for the convenience of installation at the lower extreme of screw rod 2 of fixed plate 4, seted up the spout at screw rod 2 lower extreme, made fixed plate 4 grafting spout.

Specifically, use the utility model discloses the time, behind nut 3 and 2 threaded connection of screw rod, then remove fixed plate 4, make fixed plate 4 peg graft with the spout of 2 lower extremes of screw rod, fixed plate 4 drives two inserted bars 41 and removes simultaneously, make two inserted bars 41 insert in the homonymy draw-in groove 31, at the in-process that gets into, inserted bar 41 extrudees fixture block 7, make fixture block 7 drive homonymy spring 8 shrink, and promote slide bar 6 and slide, flush mutually with fixture block 7 until slot 42, spring 8 recovers, and promote fixture block 7 and recover, make fixture block 7 get into in the slot 42 of homonymy, thereby accomplish the fixed to nut 3, avoid nut 3 and screw rod 2's relative rotation, prevent to become flexible.
