Description

TECHNICAL FIELD

[0001] The utility model relates to packing box technical field, specifically a waterproof paper product packing box. BACKGROUND

[0002] The packing box is a box for packing products, and has the functions of ensuring the safety of products during transportation and improving the grade of products. The paper product packing box is one of the packing boxes. The existing paper product packing box is pasted with a waterproof film on the outer side for waterproof function.

[0003] The existing paper product packing box also has some deficiencies in use, for example, the sealing work between the box cover and the box body is mainly achieved through mutual insertion, the connection mode is relatively complex, and a large amount of paper board needs to be cut during processing. In addition, the packing box body is replaced by a perforated mode to replace the air inside and outside, which is not convenient for adjusting the ventilation amount. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a waterproof paper product packing box to solve the problems in the background art.

[0006] The above components achieve the following effects: the side plate can be attached to the inner wall of the top end of the box body in the closed state of the box cover, the structural strength of the box body as a whole is increased, the locking piece is pushed through the waist round hole on the side plate after the box cover is closed, and the quick locking work between the side plate and the box body is completed by rotating the locking piece, conversely, the locking piece is only needed to be rotated to coincide with the waist round hole and then pulled out to release the restriction on the side plate before the box cover is opened, and the opening size of the slot hole can be adjusted by the sliding plugging assembly.

[0007] Preferably, the locking piece comprises a rotating column slidingly inserted into the side hole, one end of the rotating column is fixed with a rotating handle, and the other end of the rotating column away from the rotating handle is fixed with a locking block locked with the inner side end of the waist round hole.

[0008] The effect achieved by the above component is that the locking block at one end of the rotating column can be rotated by rotating the rotating handle, thereby avoiding the locking block from sliding along the waist round hole at will, achieving the locking effect on the box cover and the side plate, and facilitating use.

[0009] Preferably, the locking block is provided with a slope at both ends.

[0010] The effect achieved by the above component is that the slope can reduce the resistance between the waist round hole of the side plate and the locking block when the box cover is opened or closed.

[0011] Preferably, the sliding sealing assembly comprises a sliding frame fixed on the inner wall of the box body, the sliding frame is sleeved outside the slot hole, and a sealing plate for sealing work of the slot hole is slidably installed in the sliding frame.

[0012] The effect achieved by the above component is that the sealing plate can slide transversely along the inner side of the sliding frame by pushing the sealing plate, thereby achieving the opening size adjustment work of the slot hole.

[0013] Preferably, an annular groove is formed in the outer side wall of the sealing plate, and a convex ring that is in sliding cooperation with the annular groove is fixed on the inner side wall of the sliding frame.

[0014] The effect achieved by the above component is that the convex ring in cooperation with the annular groove can increase the sealing strength between the sealing plate and the sliding frame.

[0015] Preferably, a finger groove is formed in the outer side of the sealing plate.

[0016] The effect achieved by the above component is that the finger groove can facilitate the pushing work of the sealing plate by the user by using fingers.

[0017] Compared with the prior art, the waterproof paper product packaging box has the following improvements and advantages:

[0018] Firstly, after the box cover is closed, the rotating handle is pushed and the locking block passes through the waist round hole on the side plate, then the rotating handle is rotated to drive the locking block at one end of the rotating column to rotate, thereby avoiding the locking block from sliding along the waist round hole at will, and conversely, before the box cover is opened, only the rotating handle needs to be rotated until the locking block coincides with the waist round hole, and then the locking block is pulled out to release the limiting effect on the side plate.

[0019] Secondly, in the utility model, the user pushes the sealing plate by using fingers, the sealing plate can slide transversely along the inner side of the sliding frame, thereby achieving the opening size adjustment work of the slot hole. BRIEF DESCRIPTION OF DRAWINGS
