Abstract

The utility model relates to a fixing structure for barrelheads, comprising a bunghole, an outward flange arranged on the barrelhead, a hoop and a tension mechanism, wherein the hoop with V-shaped cross section is buckled at the joint of the bunghole and the outward flange on the barrelhead, and the tension mechanism is arranged at both ends of the hoop. The utility model is characterized in that an embedding ring is arranged on the bunghole above the flange; an annular embedding groove is arranged at the inner side of the barrelhead corresponding to the embedding ring and the embedding ring is embedded in the embedding groove. Compared with the prior art, the utility model has the advantages of no deformation of the barrelhead and good sealing performance of the joint between the barrelhead and the bunghole.

Description

A kind of fixed sturcture of bung

Technical field:

The utility model relates to a kind of barrel enclosed construction, particularly will cover fixing structure.

Background technology:

The existing hoop that is flute profile by the cross section with bung be fixed on the bung fixed sturcture mainly by the cross section be the hoop of flute profile, the flange that is arranged on tensioner mechanism, the bung at hoop two ends and covers evagination constitutes, bung and cover the flange butt joint of evagination, the hoop of flute profile is buckled in bung and covers the flange joint of evagination and by tensioner mechanism hoop is fixed on the flange joint.Though this kind fixed sturcture can be fixed on bung on the bung, but, because during the tensioner mechanism action, can apply the tightening force of a brute force to hoop, because bung self is less than supporting, like this, under the effect of the tightening force that binds round, bung can be out of shape, and has influenced the sealing property of bung sealing bung, and the material in the bucket is leaked out from the flange joint easily.

Summary of the invention:

Goal of the invention of the present utility model is to provide that a kind of bung can not be out of shape, the fixed sturcture of the bung of the good seal performance of bung sealing bung.

The utility model is to realize like this, comprise bung and cover evagination flange, be buckled in bung and cover evagination the flange joint the V-shaped groove in cross section hoop, be arranged on the hoop two ends tensioner mechanism, its special feature is that the bung of flange top is provided with and inlays ring, the lid inboard that correspondence is inlayed ring is provided with annular embedding groove, inlays ring and embeds in the embedding groove.During use, at embedding groove and inlay under the double action of ring, the rigidity of lid is greatly enhanced, like this, under the effect of the tightening force of hoop, lid can not be out of shape yet.

Compared with the prior art the utility model has the advantage that bung can not be out of shape, bung seals the good seal performance of bung.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the exploded view of Fig. 1;

Fig. 3 is a birds-eye view of the present utility model;

Fig. 4 is the partial enlarged drawing of Fig. 1 tensioner mechanism.

The specific embodiment:

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

As shown in the figure, the utility model comprise bung 1 and cover flange 1a, the 2a of evagination on 2, be buckled in bung 1 and cover evagination on 2

flange

1a, 2a joint the V-shaped groove in cross section opening hoop 3, be arranged on the tensioner mechanism 4 at hoop 3 two ends, its special feature is that the bung 1 of flange 1a top is provided with and inlays ring 5, lid 2 inboards that correspondence is inlayed ring 5 are provided with annular embedding groove 6, inlay ring 5 and embed in the embedding groove 6.Tensioner mechanism 4 mainly by rotation be actively socketed on a wherein end 3a of hoop 3 draw ring 4a, rotate the fork 4b that is actively socketed on hoop 3 other end 3b and constitute, the other end of draw ring 4a rotates and is actively socketed on the fork 4b, and draw ring 4a is positioned at the outside of the loose joint point 4b1 of fork 4b on hoop 3 at the loose joint point 4a1 on the fork 4b.Torque arm 4a one end rotates in the loose joint present 7, and seat 7 is fixed on by cold welding 9 on the wherein end 3a of hoop 3, and in the fork 4b swing loose joint present 8, seat 8 is fixed on the other end 3b of hoop 3 by cold welding 9.During use, hoop 3 is buckled in bung 1 and covers flange 1a, the 2a joint of evagination on 2, swing fork 4b then, make two loose joint point 4a1, the 4a2 of draw ring 4a be positioned at the inboard of the loose joint point 4b1 of fork 4b on hoop 3, like this, bind round 3 connections that just are fixed.Ring 5 and lid 26 inboard of the annular embedding grooves of inlaying at bung 1 are provided with the V-shaped seal ring in cross section 10, so that the cargo-carring article of institute in the bucket are sealed.

Claims

1, a kind of fixed sturcture of bung, comprise bung and cover evagination flange, be buckled in bung and cover evagination the flange joint the V-shaped groove in cross section hoop, be arranged on the hoop two ends tensioner mechanism, the bung that it is characterized in that flange top is provided with inlays ring, the lid inboard that correspondence is inlayed ring is provided with annular embedding groove, inlays ring and embeds in the embedding groove.

2, the fixed sturcture of bung according to claim 1, it is characterized in that tensioner mechanism mainly by rotation be actively socketed on a wherein end of hoop draw ring, rotate the fork be actively socketed on the hoop other end and constitute, the other end of draw ring rotates and is actively socketed on the fork, and draw ring is positioned at the outside of the loose joint point of fork on hoop at the point of the loose joint on the fork.

3, the fixed sturcture of bung according to claim 2, it is characterized in that torque arm rotate loose joint present on, seat is fixed on the wherein end of hoop by cold welding, on fork swing loose joint was present, seat was fixed on the other end of hoop by cold welding.
