Detailed Description

The present invention is described in further detail below with reference to the accompanying drawings.

The plastic packaging box with the upper and lower split type water seepage preventing structure (the upper and lower split type water seepage preventing plastic packaging box structure) is formed by assembling an upper box body 1, a lower box body 2 and a V-shaped rubber ring 5, and comprises an upper box body line contact and lower box body upper V-shaped rubber ring pressing structure and a double-gradient rain eave water seepage preventing structure, wherein the specific assembling structure is shown in figure 6.

The upper box body 1 is matched with the lower box body 2, and the upper box body is provided with a bulge and a lower box body groove; the bulge is of a V-shaped structure, and the matching of the rubber ring in the groove and the bulge is of a V-shaped structure (the original structure is changed into a conical pressing bulge); the outer side end of the upper box body (after extending outwards on the basis of the original structure) is positioned outside the outer side end of the lower box body to form an edge of which the outer side surface covers the opening part of the lower box body; the length of the edge of the upper box body reaches the lower edge of the opening part of the lower box body; the inner surface at the border of the upper box body is provided with a step, the outer side surface of the mouth part of the lower box body is provided with a step, the step is consistent with the inner surface structure of the step at the border of the upper box body, and the step and the step are matched (double-gradient rain-proof eaves) to form a waterproof surface.

Go up the box oral area and outwards extend the back on original structure basis, compare fig. 1(c) and fig. 6, former trapezoidal compresses tightly the arch and changes into the toper and compress tightly the arch, increases two terraces rain eaves, and rain eaves length is to lower box oral area lower limb. The waterproof plane is increased to lower box oral area, with the cooperation of the two echelon rain eaves of last box, increases packing box oral area intensity simultaneously. The rubber ring is changed from a square section to a rectangular section with a V-shaped groove.

The packing box is provided with a lock catch. Handles are arranged on two sides of the packing box.

During assembly, firstly, the V-shaped rubber ring is arranged in the rectangular groove of the lower box body, and the V-shaped groove opening of the rubber ring is upward; secondly, assembling the upper box body and the lower box body, and aligning and matching the conical pressing bulge at the opening part of the upper box body with the V-shaped rubber ring of the lower box body; thirdly, the upper box body and the lower box body are assembled and compressed through the lock catch, the conical protrusion of the upper box body is in contact and compression fit with the V-shaped rubber ring in the groove of the lower box body to the maximum extent, and meanwhile, the upper box body and the lower box body are assembled to form a double-gradient rainproof eaves to prevent water (including rainwater or snow melting water) from permeating into the packing box from the upper part, so that the whole water seepage prevention effect of the packing box is effectively improved.

3) Principle of operation

The principle of the V-shaped rubber ring pressing structure is changed from pressing surface contact to line contact, so that the stress area is reduced, the pressure intensity is increased, and the surface contact matching is increased to the maximum extent.

Rainwater in the double-ladder rain-proof eave structure cannot permeate in the counter-flow mode through the fit clearance between the upper box body and the lower box body.

The key of the invention adopts a V-shaped rubber ring to compress and a double-ladder rain-proof eaves structure, thereby effectively preventing external water from infiltrating into the box.

4) According to the structure and the packaging requirements of ammunition products, when the products are designed, V-shaped rubber ring pressing and double-gradient rain eave water seepage prevention structural design are adopted at the matching parts of an upper box body and a lower box body of a plastic packaging box.
