Abstract

The utility model relates to a composite steel plastic barrel, belonging to a container for storing liquid. The composite steel plastic barrel comprises a metal barrel and a plastic barrel chamber. The composite steel plastic barrel is characterized in that the opening of a barrel cover is provided with a ring pillar-shaped flanging. The upper part of the screw ring of the opening of the barrel chamber is provided with an outwards convex shoulder. The ring pillar-shaped outer wall of the screw ring is matched with the ring pillar-shaped flanging of the opening of a barrel cover. In addition, the ring pillar-shaped flanging can clamp the outwards convex shoulder in the upper part of the screw ring. The screw ring of the opening of the barrel chamber of the composite steel plastic barrel can be made in one time. Thus, prefabricated components are not required. The composite steel plastic barrel has the advantages of simple structure, low manufacture cost, good intensity and leakage elimination.

Description

Composite steel plastic barrel

The utility model belongs to container class, relates to a kind of combined type steel of depositing liquid and moulds bucket.

Mould in the compound bucket at existing steel, the courage mouth of Plastic Drum courage is the annulated column shape screw socket circle with internal and external screw thread, after being installed in the bucket cover port of metal staving, need to piece together tightly on bung by piecing together circle, in order to avoid the screw socket circle sinks the inner cap and the tapped enclosing cover of the band seal ring of just screwing on then in use.This steel is moulded the bunghole part separation structure complexity of compound bucket, is difficult for making and the cost height.

The purpose of this utility model provides a kind of simple in structure, is easy to make and steel that cost is low is moulded compound bucket.

The technical scheme that realizes above-mentioned purpose is: make the bung mouth have annulated column shape flanging, the tapped screw socket circle top of bucket courage mouth has outer convex shoulder, the annulated column shape outer wall of screw socket circle matches with the annulated column shape flanging of bung mouth, and the annulated column shape flanging of bung mouth can block the outer convex shoulder on screw socket circle top.

After adopting technique scheme, it is further simple that the utility model is just moulded compound barrel structure than existing steel, not only saved the externally threaded manufacturing of screw socket circle, also saved the assembly cap of rest screw socket circle, only just can hold the outer convex shoulder of screw socket circle with the flanging of bung mouth, make the unlikely in use sinking of screw socket circle, not only easy to manufacture, also reduced manufacturing cost.

Below in conjunction with accompanying drawing structure of the present utility model is further described specifically.

Fig. 1 moulds the overall semisectional view of bucket for combined type steel of the present utility model.

Fig. 2 is the one-shot forming inlet of Plastic Drum courage of the present utility model or the sectional arrangement drawing of exhausr port and bung mouth.It also is the I part enlarged drawing of Fig. 1.

Fig. 3 is a bucket end part sectional view of the present utility model, also is the II part amplification view of Fig. 1.

The utility model combined type steel is as shown in Figure 1, 2 moulded bucket, and its external metallization bucket is to be made of bung (1), staving (3) and the bucket end (4).Staving (3) is to be formed by the metal sheet roll extrusion, can roll out several multiple tracks ring-type convex tendons, with the radial rigidity of roller hoop drum.Bung (1) and the bucket end (4) all are to be stamped to form with metal sheet.Bung (1) is provided with one or two inlet or exhausr port, also is the bung mouth, and the bung mouth has annulated column shape flanging (10).The Plastic Drum courage (2) that is installed in the metal drum adopts plastics blow molding to make, and size is slightly larger than staving (3).The top of Plastic Drum courage (2) is provided with one or two inlet or exhausr port accordingly, also is bucket courage mouth.Bucket courage mouth has tapped screw socket circle (9) and its top has outer convex shoulder (8).When making the combined type steel and mould barrel, the screw socket circle (9) with convex shoulder outside the top (8) with bucket courage mouth is pressed into the bung mouth with special tool earlier, and make convex shoulder (8) outside the top of screw socket circle (9) of barrel courage mouth pass the annulated column shape flanging (10) of bung mouth, the annulated column shape outer wall of screw socket circle (9) matches with the annulated column shape flanging of bung mouth, and can block the outer convex shoulder (8) on screw socket circle (9) top, then, bung (1) is pushed in the staving (3) together with bucket courage (2), at the bottom of loading onto barrel (4) and be placed into and carry out rolling on the production machine and connect and form one (referring to Fig. 3), the screw socket circle (9) that inner cap (6) is put seal ring (7) again and be contained in a barrel courage (2) is gone up and is got final product.In use, the liquid of in bucket courage (2), packing into, screw on again behind the inner cap (6) that is with seal ring (7), also can be packaged with sheet iron lid (5) on screw socket circle (9) top of bucket courage mouth, the bottom of sheet iron lid (5) can have on outer convex shoulder (8) lower surface, top that is stuck in screw socket circle (9) of closing up and close up it by specialized equipment, seals inner cap (6) and the further safety and the anti-theft of enhancing barrel courage mouth with this.

The screw socket circle of the bucket courage mouth of prior art is owing to have internal and external threads thereby can only adopt the way of prefabricated circle and heat seal, improperly easily causes seepage and the easy bad phenomenon such as rotation of screw socket circle when using as heating during manufacturing, and cost is also very expensive.The utility model can make the screw socket circle of barrel courage mouth not adopt prefabricated circle and negative thread one-shot forming during fabrication, has both eliminated the seepage phenomenon, and intensity is improved, and is not only easy to manufacture but also reduced cost.

Fig. 3 is the bead structure figure of the bucket end (4).This structure also is applicable to bung (1).Among the figure, the crimping of the bucket end (4) surrounds staving (3), and is engaged after compressing, and the edge that this structure makes the combined type steel mould bucket has enough rigidity.

Claims

1, a kind of combined type steel is moulded bucket, its external metallization bucket is by bung (1), staving (3) and the bucket end (4) constitute, bung (1) is provided with the bung mouth, the top that is installed in the Plastic Drum courage (2) in the metal drum is provided with barrel courage mouth and a bucket courage mouth has tapped screw socket circle (9), it is characterized in that: the bung mouth has annulated column shape flanging (10), screw socket circle (9) top of bucket courage mouth has outer convex shoulder (8), the annulated column shape outer wall of screw socket circle (9) matches with the annulated column shape flanging (10) of bung mouth, and annulated column shape flanging (10) can block the outer convex shoulder (8) on screw socket circle (9) top.
