Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box with a ventilation hole adjustment mechanism. Background Technology

[0002] Packaging boxes are used to package products. Common types of packaging boxes include hinged boxes, drawer boxes, and corrugated boxes. Packaging boxes for storing fruit usually have ventilation holes to improve air permeability and prevent the fruit from rotting.

[0003] However, the ventilation holes in the aforementioned packaging boxes are mostly fixed structures with fixed positions and sizes. Different types of fruits require different levels of gas flow, so this type of packaging box has significant limitations.

[0004] To address the aforementioned issues, a packaging box with an adjustable ventilation hole mechanism is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a packaging box with a ventilation hole adjustment mechanism, which solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution: A packaging box with a ventilation hole adjustment mechanism includes an outer box body and an inner box body connected by a drawer. The outer box body includes an integrally formed outer box cardboard. The outer box cardboard has reserved grooves on its two outer side walls. Ventilation holes penetrating the outer box cardboard are provided in the reserved grooves. An adjustment mechanism is slidably arranged on the reserved grooves. The adjustment mechanism includes an adjustment belt that is slidably fitted with the reserved groove.

[0007] Furthermore, the outer belt body of the adjustment belt has circular adjustment and ventilation holes, and the inner belt body of the adjustment belt has slot-shaped internal grooves.

[0008] Furthermore, the connecting ends of the adjustment belt are sewn with Velcro that is mutually adhesive, and a handrail frame is also glued and fixed to the outer wall of the adjustment belt.

[0009] Furthermore, the inner box body includes an integrally formed inner box cardboard, and two side walls of the inner box cardboard are provided with inner box ventilation holes. The inner box ventilation holes have the same diameter as the outer box ventilation holes and are aligned and connected.

[0010] Furthermore, the outer box ventilation hole is interconnected with the inner slot and the adjustment ventilation hole.

[0011] Furthermore, a fixing pin is pressed at the bottom interface of the outer cardboard box.

[0012] The beneficial technical effects of this utility model are as follows: This invention features an adjustment mechanism on the packaging box. An adjustment strip, which slides and wraps around a pre-reserved groove on the outer box, is used to adjust the opening and closing of the ventilation holes on the adjustment strip that correspond to the inner and outer boxes. This allows for adjustable ventilation of the packaging box, making it suitable for different fruits and ensuring their freshness. Attached Figure Description

Detailed Implementation

[0015] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0016] like Figures 1-4As shown, this embodiment provides a packaging box with a ventilation hole adjustment mechanism, including an outer box body 1 and an inner box body 2 assembled in a drawer-like manner. The outer box body 1 includes an integrally formed outer box cardboard 101. Reserved slots 102 are provided on the outer two side walls of the outer box cardboard 101. Ventilation holes 103 penetrating the outer box cardboard 101 are provided within the reserved slots 102. An adjustment mechanism 3 is slidably disposed on the reserved slots 102. The adjustment mechanism 3 includes an adjustment band 301 slidably fitted with the reserved slots 102. Circular adjustment ventilation holes 302 are provided on the outer band of the adjustment band 301, and slotted inner grooves 305 are provided on the inner band of the adjustment band 301.

[0017] In the above structure, the adjusting band 301 is made of soft plastic with a smooth outer wall and elasticity. It is tightly connected to the reserved groove 102 and can slide freely with the reserved groove 102. The reserved groove 102 is only opened on one side of the outer wall of the outer box 1. The adjusting band 301 is inside the outer box 1 and forms a pressing tendency with the inner box 2, which is beneficial to limit the inner box 2.

[0018] The connecting ends of the adjustment band 301 are sewn with Velcro 304 that are mutually adhesive. A handrail 303 is also glued and fixed to the outer wall of the adjustment band 301. This arrangement allows for easy disassembly of both ends of the adjustment band 301. After being glued, it forms a U-shaped ring structure that fits onto the cardboard wall of the outer box 1. The handrail 303 is made of the same material as the adjustment band 301. During adjustment, it is convenient to pull the adjustment band 301 left and right. In addition, it also serves as a portable packaging box.

[0019] The inner box body 2 includes an integrally formed inner box cardboard 201. Two side walls of the inner box cardboard 201 have inner box ventilation holes 202. The inner box ventilation holes 202 have the same diameter as the outer box ventilation holes 103 and are aligned and connected. The outer box ventilation holes 103 are interconnected with the inner slot 305 and the adjusting ventilation holes 302.

[0020] In the above structure, the left and right adjustment distance of the inner slot 305 is 30cm. By moving left and right, the adjustment vent 302 and the outer box vent 103 are misaligned and blocked, so as to adjust the opening area. The inner box vent 202 exhausts the gas in the inner box 2 to form a circulating airflow.

[0021] A fixing pin 104 is pressed at the bottom interface of the outer box cardboard 101, and the fixing pin 104 locks the end of the outer box cardboard 101 in a fastening manner.

[0022] The working principle of this device is as follows: When using this device, the adjustment strap 301 is laid along the reserved groove 102 on the outer box 1, and the two ends of the adjustment strap 301 are connected by Velcro 304. Finally, the adjustment vent 302 is aligned with the outer box vent 103 on the outer box 1, and the inner box 2 containing the fruit is pushed into the outer box 1. The inner box vent 202 of the inner box 2 is aligned and connected with the outer box vent 103 and the adjustment vent 302. This is the initial position.

[0023] When adjustment is needed, the adjustment strap 301 is slid along the reserved groove 102 by pulling the armrest frame 303 left and right, so that the adjustment vent 302 and the outer box vent 103 are misaligned, thereby achieving the purpose of adjusting the ventilation opening.

[0024] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0025] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
