Split-type wrenching-type preservation box

Abstract

The invention relates to a split-type wrenching-type preservation box, comprising a box body and a box cover, wherein a fixed slot is arranged below the box cover, the fixed slot is provided with a seal ring, and the seal ring is sealed with the opening of the box body. The split-type wrenching-type preservation box is characterized in that the outer wall of the box body is provided with a connection block, the connection block is provided with a connecting slot, the connecting slot is internally provided with a wrench, the two ends of the wrench are provided with blocking tenons, the blocking tenons are movably connected with the connecting slot in the connection block, the wrench is provided with a clip, the box cover is provided with a fixed side, and the clip of the wrench is clamped and matched with the fixed side. The outer side of the box body is provided with the connection block, the connection block is provided with the connecting slot, the connecting slot and the wrench are connected, the wrench is independently injected and moulded, the two ends of the wrench are provided with the blocking tenons, and the wrench is arranged in the connecting slot of the box body by virtue of the blocking tenons, thus mounting is convenient, the generality is good, the blocking tenons and the connecting slot are connected in a rotating way by virtue of spindle and can not rebound or slip off, the influence of repeated rotation is avoided, the service life is long, the wrench and the box body or box cover are in a split structure, a die is easy to make, a demoulding mechanism is simple, the rejection rate is low, and the production efficiency is high.

Description

Technical field [0001] The invention relates to a fresh-keeping box, in particular to a split type lower-pull type fresh-keeping box, which belongs to daily necessities. Background technique [0002] Due to the tightness of the fresh-keeping box, it avoids microbial contamination, maintains the freshness of food, and prevents various food odors in the refrigerator, so it is widely used in daily life. In order to maintain the tight fit between the box body and the lid, the existing fresh-keeping box usually has a wrench on the lid, a clamp on the wrench, and a flange on the outer wall of the box. The clamp is connected with the flange by the wrench. The box body and the box cover are clamped together. The disadvantages of this product are as follows: First, the wall of the box cover and the wrench is thick, and the wall at the joint between the wrench and the box cover is very thin in order to be able to pull the wrench. During injection molding, the material must be injected fro...

AI Technical Summary

Problems solved by technology

In order to keep the tight fit between the box body and the box cover, the existing fresh box usually has a wrench on the box cover, a clip on the wrench, and a flanging on the outer wall of the box. Cooperate to clamp the box body and the box cover, and the disadvantages of this product are: First, because the wall of the box cover and the wrench is thick, and the wall of the connection between the wrench and the box cover is very thin in order to be able to pull the wrench, so During injection molding, the material must be injected from the injection hole in the middle, and then reach the wrench through a very thin connection. The time is long and the speed is slow, which reduces the production efficiency; the second is that the connection is too thin, the injection filling is difficult, and it is easy to scrap ; The third is that after the wrench is pulled many times, the connection is easy to break, and the wrench is integrated with the box cover through the connection. Once the wrench is broken, it cannot be replaced, and the entire box cover is scrapped; On the other hand, the wrench and the box cover are integrated, and there is a rebound force in the fastening direction, which makes the clip easily slip off from the flange on the outer wall of the box; fifth, the box cover and the wrench are integrally formed, the mold processing is difficult, and the demoulding mechanism Complex, large mold investment
