Abstract

The utility model relates to a package plastic bucket for oil, comprising a bucket body and a bucket cover. The bonding position of the bucket body and the bucket cover is provided with a sealing mechanism which is matched with the bucket body and the bucket cover. The package plastic bucket for oil is characterized in that the sealing mechanism is provided with rectangular convex ribs on the outer wall of the mouth of the bucket body; the inner wall of the mouth of the bucket body is provided with convex surface which inclines inwardly. The inner wall of a hanging sleeve of the bucket cover is provided with clamping ribs which are matched with the rectangular convex ribs. A lower flared sealing ring is arranged inside the bucket cover. The lower flared sealing ring is inserted into the mouth of the bucket body and is matched with the inclined convex surface of the inner wall of the bucket body. The outer wall of the mouth of the bucket body of the utility model is provided with the rectangular convex ribs which are hooked and restricted by the clamping ribs of the bucket cover, and the inclined convex surface of the inner wall of the mouth of the bucket body is matched with the lower flared outer wall of the sealing ring in the bucket cover, so the defect that the sealing ring has poor function caused by that the outwardly inclined circular arc of the inner wall of the mouth of the bucket body is too smooth is overcome. The sealing ring is in interference fit with the inner wall of the mouth of the bucket body, so the sealability is improved, and the purpose of oil leak preventing is achieved.

Description

The POL packing Plastic Drum

Technical field

The utility model relates to the POL packing bucket, is specially adapted to pack oil plants such as lubricating oil (for example automobile engine oil) or various emulsion paints.

Background technology

Traditional POL packing bucket adopts iron sheet barrel mostly, because the good rigidly of iron sheet, elastic deformation is little, thus be not easy to jump phenomenons such as lid or leakage of oil, but, be extensive use of Plastic Drum now because iron sheet barrel makes trouble, and useless bucket is handled problems such as difficulty.Though and the kind of the existing Plastic Drum shape and structure that is used to pack oil plant is more, because elasticity of plastics is bigger, smoother again, thus leak tightness poor for the ubiquity that is connected between bung and the staving, seepage can occur, also can cause sometimes to jump and cover phenomenon.Therefore, how to solve the hermetically-sealed construction of bung be very urgent problem to the POL packing Plastic Drum.

Summary of the invention

The purpose of this utility model provides and a kind ofly all is shaped on hermetically-sealed construction at the oral area of staving and the inside and outside wall between the bung, and both install the non-leakage POL packing Plastic Drum in back.

The technical scheme of the utility model POL packing Plastic Drum is: be made up of staving and bung, be shaped on the sealing mechanism of working in coordination in the junction of staving and bung, it is characterized in that described sealing mechanism is that outer wall at the staving oral area is shaped on the rectangle convex tendon, inwall at the staving oral area is shaped on introversion (closing in) convex surface, hanging sleeve inwall at bung is shaped on the card muscle, the card muscle matches with the rectangle convex tendon, be shaped on the seal ring of enlarging down in bung, following enlarging seal ring inserts in the bung and matches with the introversion convex surface of staving mouth inner wall.And be shaped on reinforcing pad in the following outside of bowl opening, and reinforcing pad is shaped on step, and step matches with the hanging sleeve end opening of bung.

POL packing Plastic Drum of the present utility model compared with the prior art, have following characteristics: the outer wall at the staving oral area is shaped on leak free rectangle convex tendon, rectangle convex tendon and the restriction of bung clamp bar hooking, by not taking out behind the last bung, especially the introversion convex surface of bung inwall matches with the following enlarging outer wall of bung seal ring, overcome bung inwall flare circular arc smooth transition in the prior art, cause the critical defect of seal ring effect difference, and this seal ring becomes interference fit with the bung inwall, leak tightness improves greatly, reaches purposes such as oil tight liquid.

The specific embodiment

The utility model discloses a kind of POL packing Plastic Drum that is used to pack materials such as lubricating oil (machine oil) or emulsion paint, its essential structure is made up of staving and bung, the shape of staving and bung can be cylindrical or oval or square etc., junction at staving 1 and bung is shaped on the sealing mechanism of working in coordination, because both rely on the combination of self sealing of working in coordination, liquid such as oil plant can not seepage, so sealing mechanism is one of gordian technique of bucket.Feature of the present utility model is that sealing mechanism is that the outer wall of staving 1 oral area is shaped on rectangle convex tendon 3, inwall at the staving oral area is shaped on introversion convex surface 4, as shown in Figure 1 and Figure 2, bung is received little, rectangle convex tendon 3 and introversion convex surface 4 make the inside and outside wall of bung all obtain sealing, the one, play inside and outside sealing function, the 2nd, intensity is good again.Hanging sleeve (outer ring) inwall at bung 2 is shaped on card muscle 5, card muscle 5 matches with rectangle convex tendon 3, both hook mutually, so in case by behind the last bung, just get to come out, both do not separate, be shaped on the seal ring 6 of enlarging down in bung 2, following enlarging seal ring 6 inserts in the bung (staving oral area) and matches with the introversion convex surface 4 of staving mouth inner wall, and prior art is made enlarging to bung usually, so seal ring skids off easily, do not have sealing function.It is to the extruding of the outer wall of seal ring 6 that introversion convex surface 4 has been arranged, and adds that again seal ring 6 end openings enlarge, and both become interference fit, pastly more goes out tightly more, can not skid off.And the following outside 1 mouthful of staving is shaped on reinforcing pad 7, and reinforcing pad 7 is shaped on step 8, and step matches with hanging sleeve 9 end openings of bung 2, plays additional lock flush fit effect between staving and the bung.

Claims

1, POL packing Plastic Drum, formed by staving and bung, be shaped on the sealing mechanism of working in coordination in the junction of staving and bung, it is characterized in that described sealing mechanism is that outer wall at staving (1) oral area is shaped on rectangle convex tendon (3), inwall at the staving oral area is shaped on introversion convex surface (4), hanging sleeve inwall at bung (2) is shaped on card muscle (5), card muscle (5) matches with rectangle convex tendon (3), be shaped on the seal ring (6) of enlarging down in bung (2), following enlarging seal ring (6) inserts in the bung and matches with the introversion convex surface (4) of staving mouth inner wall.

2, POL packing Plastic Drum as claimed in claim 1 is characterized in that the following outside of staving (1) mouth is shaped on reinforcing pad (7), and reinforcing pad (7) is shaped on step (8), and step matches with hanging sleeve (9) end opening of bung (2).
