Description

Technical Field

[0001] The utility model belongs to the technical field of storage boxes, and in particular relates to a storage box with a double-opening cover structure. Background Art

[0002] Existing storage boxes usually use a snap-fit ​​structure in the process of closing the box lid. When in use, the snap-fit ​​structure is easy to get stuck and difficult to pry apart, which makes the operation troublesome and affects the appearance of the storage box. Among them, the "self-locking storage box" disclosed in the application number "CN202321343475.1" is also an increasingly mature technology. Through the arrangement of the installation cavity, the connecting page and the abutment block, while improving the sealing performance of the cover body, there is no need to set up a snap-fit ​​structure separately, thereby ensuring the overall aesthetics of the storage box. However, the device also has the following defects: when the above-mentioned equipment is in use, the fixed connection point structure is not strong enough. When it is dropped or hit, the connection part is easy to loosen, causing the cover body to fall off. At the same time, the sealing performance of the storage box is not high, which easily causes dust to enter the storage box. Utility Model Content

[0003] The utility model aims to provide a storage box with a double-opening cover structure, aiming to solve the problems in the prior art that the fixed connection point structure is not strong enough, the connection part is easy to loosen after being dropped or hit, causing the cover to fall off, and at the same time the sealing of the storage box is not high, which easily causes dust to enter the storage box.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: it comprises a box body and a closing cover, the closing cover is hinged to both sides of the top of the box body, an I-shaped slide groove is provided in the middle of the closing cover, an I-shaped block is slidably connected in the I-shaped slide groove, a return spring is provided on one side of the inner wall of the I-shaped slide groove, slots are provided on both sides of the closing cover, movable push blocks are provided at both ends of the I-shaped block, the movable push block is slidably connected in the slots, L-shaped hook blocks are provided on both sides of the bottom of the I-shaped block, movable grooves are provided on both sides of the bottom of the closing cover, the L-shaped hook block is slidably connected in the movable groove, concave limit blocks are provided at the four corners of the top of the inner wall of the box body, and the L-shaped hook block is engaged with the concave limit block.

[0005] In an implementation scheme of a storage box with a double-opening cover structure of the utility model, a sealing rubber pad is provided on the bottom side of the closed cover.

[0006] In this solution, when the closing cover is closed, the sealing rubber pad abuts against the opening of the box body to prevent dust from entering the box body.

[0007] In an implementation scheme of a storage box with a double-opening cover structure of the utility model, rubber anti-sliding blocks are distributed on the surface of the movable push block.

[0008] In this solution, the movement of the push block is facilitated by a plurality of rubber anti-slip blocks on the surface of the push block.

[0009] In an implementation scheme of a storage box with a double-opening cover structure of the utility model, the closed covers located opposite to each other are alternately provided with dustproof plates.

[0010] In this solution, when the closing cover is closed, external dust is isolated by the dustproof plate, thereby improving the sealing performance of the box body.

[0011] In an implementation scheme of a storage box with a double-opening cover structure of the utility model, opposite surfaces of the dustproof plates that are located opposite to each other are both installed with magnetic stones.

[0012] In this solution, the magnetic stones on the dustproof plates that are located opposite to each other are attracted to each other, thereby improving the tightness between the dustproof plates.

[0013] In an implementation scheme of a storage box with a double-opening cover structure of the utility model, a handle is hinged on the top of the closed cover.

[0014] In this solution, the handle makes it easy to take the box body and carry the box body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1) The I-shaped block moves in the I-shaped slide groove by toggling the moving push block, the I-shaped block squeezes the reset spring, and the L-shaped hook block moves. When the closing cover is turned over and the closing cover is closed, the moving push block is released, and the reset spring pushes the I-shaped block to drive the L-shaped hook block to move in the movable groove. The L-shaped hook block is engaged with the concave limit block. The four L-shaped hook blocks are engaged with the concave limit blocks to improve the tightness between the closing cover and the box body after being fixed, and the fixed connection is relatively firm and not easy to loosen;

[0017] 2) When the closing cover is closed, the sealing rubber pad is pressed against the opening of the box body to prevent dust from entering the box body. When the closing cover is closed, the dustproof plate is used to isolate external dust, thereby improving the sealing of the box body. BRIEF DESCRIPTION OF THE DRAWINGS
