Description

Foldable plastic turnover box

Technical field

The utility model relates to a storage turnover box, in particular to a foldable injection molding storage turnover box.

Background technique

In the wholesale and retail process of commodities, turnover boxes are needed to facilitate the transportation, turnover and storage of commodities. In industrial production, especially assembly line operations, turnover boxes are used more frequently and are mostly used to store semi-finished machinery, electronics and other products.

Existing turnover boxes are roughly divided into cardboard boxes, wooden crates, plastic hollow crates, hard plastic boxes, etc. from the material. The cardboard box can be folded when it is empty, but the disadvantage is that it cannot be used multiple times and the cost is high; the wooden box will destroy the natural ecological balance due to the large amount of wood used, and the wooden box is also heavy and inconvenient to carry; the plastic hollow box and hard plastic The box has the advantages of light weight and reusability, and has become the leading product in the turnover box. Among them, the foldable plastic turnover box is more popular because it can be folded when empty, so it takes up less space. It is widely used in industrial production due to its advantages such as easy portability.

In the prior art, the foldable plastic turnover box consists of a lower bottom plate, a front side plate, a rear side plate, a left side plate and a right side plate to form a rectangular open box body, and the front side plate, the rear side plate, the left side plate and the The lower edge of the right side board is hinged on the lower bottom board; the ends of the left side board and the right side board respectively extend a rib, and the bodies at the two ends of the left side board and the right side board are respectively provided with elastic arms , the arm end of the elastic arm is provided with a bump towards the inside of the box, and one side of the bump is provided with a transition slope, and a cavity is formed between the bump and the rib to form a Y-axis buckle positioning structure; the left side There are hooks on the ribs at both ends of the side plate and the right side plate, corresponding to the hooks are correspondingly provided with holes on both ends of the front side plate and the rear side plate, and the hooks and the holes cooperate to form an X-axis buckle positioning structure . When in use, the ends of the front and rear side panels are located inside the ribs of the left and right side panels, and slide into the cavity between the bump and the ribs along the transition slope on the elastic arm to form the opening of the turnover box. state; when it needs to be folded, the user can press the protrusions on the elastic arms of the left and right side panels from the inside to the outside, so that the protrusions avoid outwards, the positioning buckle is unlocked, and the front and rear side panels and the left and right side panels are ready It can be turned to the inside of the box to complete the folding.

The folding turnover box with the above structure has a relatively complicated locking structure between the side panels, which brings inconvenience to the injection molding, especially the structure of the elastic arm is integrally formed with the box body, which has high requirements for the injection mold and will directly affect However, during use, when the side panel is unlocked, it is necessary to press the four elastic arm protrusions at the ends of the left and right side panels in turn, which is very troublesome. At the same time, the elasticity of the elastic arm depends on the plastic itself Formed by the flexibility, frequent pressing and the influence of the surrounding environment on the plastic, the elastic arm will break. Once broken, it cannot be repaired, and the entire turnover box can no longer be used normally, which affects its service life.

Contents of invention

The purpose of the utility model is to provide a foldable plastic turnover box which is convenient to assemble and disassemble, simple in structure and easy to realize.

In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: including the bottom plate, the flaps symmetrically arranged on one set of opposite sides of the bottom plate and the side plates symmetrically arranged on the other set of opposite sides of the bottom plate, the flaps and the side plates The bottom edges of the flaps are respectively hinged with the bottom plate, the two ends of the side plates are provided with outwardly extending and bent ribs, and the top two ends of the flaps are respectively provided with locking structures connected with the ribs, and are also provided on each A driving mechanism in the mounting groove on the outer side wall of the flap, the driving mechanism is composed of a button and a return spring, the button is slidingly connected to the mounting groove through a connecting structure, one end of the returning spring is fixed on the button, and the other end It is stuck in the card slot on the wall corresponding to the installation groove, and the left and right sides of the button are provided with slide rails arranged obliquely; the lock structure is located on both sides of the drive mechanism, and each lock structure consists of a movable pin, a set It is composed of a transverse guide groove on the side wall of the flap and at least one fixed pin. The movable pin is arranged in the transverse guide groove, and a transverse pin hole is provided on the rib corresponding to the movable pin, and the inner end of the movable pin passes through the pin Slidingly connected in the slide rail on the corresponding side, when the return spring is in the reset state, the pin rod is located at the outer end of the slide rail, and the outer end of the movable pin is located in the pin hole; the fixed pin is vertically arranged on the outer wall of the flap, And the rib corresponding to the fixing pin is provided with a through hole matched with it.

The so-called flap, relative to the side panels, is the panel surface that is located inside the ribs at both ends of the side panel when the box is unfolded and fixed, and is folded up first when the box is folded. It is easy to fold, and usually the shorter side of the box body is defined as the flap, and the longer side is the side panel; whether it is the outer wall of the flap or the side panel, there are many reinforcing ribs distributed to increase the strength of the box. The compressive strength itself, therefore, the installation groove is formed by using the flanging of the top surface of the box body and the reinforcing ribs arranged transversely on the outer side wall of the flap.

In the above technical solution, when there is no other external force, the return spring resets the button by its elastic force, and this state is the "reset state". In this state, the inner end of the movable pin is at the outer end of the corresponding slide rail, while the outer end of the movable pin is located in the pin hole of the side plate. When the button is pressed, the vertical direction is restricted by the transverse guide groove. position, the movable pin and the pin rod connected to it can only move horizontally, so the pin rod slides inward in the obliquely set slide rail until the inner end of the slide rail, and at the same time drives the movable pin to retract inward and break away from the side plate The constraint of the pin hole achieves the purpose of unlocking; those skilled in the art can know that according to the working state of the return spring and the state of the position in the slide rail where the movable pin is located against the lock, when the return spring selects the pressure reed, it can be divided into two types: The spring is set under the button and above the two installation methods. In the former installation method, the slide rail is arranged obliquely in a figure-eight shape with a narrow top and a wide bottom. Press the button downward to compress the return spring to work; while the latter installation method is used , the drive mechanism needs to be turned 180 degrees relative to the installation direction of the former, that is, the slide rails are arranged obliquely in an inverted splayed shape with a wide top and a narrow bottom. When unlocking, the button needs to be pulled upwards to compress the return spring above the button; The spring can also be an extension spring. At this time, its installation position and the layout of the slide rail are just opposite to those of the compression reed.

In the above technical solution, a plurality of reinforcing ribs are arranged in the installation groove, and the transverse guide groove is surrounded by a combination of reinforcing ribs.

In the above technical solution, the connection structure between the button and the flap is that a slide bar is provided on the back of the button, and an elastic hook is provided at the end of the slide bar, corresponding to the side wall of the flip panel at the slide bar. A guide hole is provided, and the slide bar is clamped in the guide hole.

Another solution is: the connection structure between the button and the flap is that in the installation groove, the two ends of the button are respectively provided with longitudinally arranged positioning reinforcing ribs, and the distance between the positioning reinforcing ribs is the same as that of the button. The width is coordinated to form a longitudinal guide groove; the positioning reinforcing rib is provided with a fixing hole corresponding to the movable pin, and the fixing hole communicates with the transverse guide groove. The positioning reinforcing rib can be used as the side wall of the longitudinal guide groove of the button on the one hand, and on the other hand, because the movable pin is inserted in the fixing hole on the reinforcing rib, it can be used as fixing to the driving mechanism.

The working principle of the utility model is: when the box body is in the unfolded state, the movable pin is located at the outer end of the slide rail, and the movable pin is inserted into the horizontal pin hole on the sidewall to form a lateral fixation of the turning plate relative to the box body, which can prevent the turning plate On the other hand, the fixed pin on the flap and the through hole on the rib are fixed together to form a fixation to the side panel and prevent the side panel from turning outward, thereby forming a mutual connection between the flap and the side panel. Constraints to achieve a stable state of box assembly; when it needs to be folded, press the button to compress the return spring, so that the button moves along the guide hole (or longitudinal guide groove) on the side wall of the flap, and at the same time, it is located in the left and right slide rails. The pin rod drives the movable pin to slide along the direction of the slide rail, and moves from the outside of the slide rail to the inside of the slide rail in the self-resetting state. Since the distance between the outer ends of the slide rails is greater than the distance between the inner ends, the movable pin shrinks inward and breaks away from the stopper. At this time, the box body loses the horizontal constraint, and the flap can be turned inward. At the same time, the fixed pin breaks away from the through hole on the rib, and the box body also loses the longitudinal constraint. The side panels can also be turned inward. Turn it inside out to complete the folding, and the button on the flap can be released when the movable pin is out of the pin hole. end. When unfolding the cabinet again, you only need to erect the side panels one after another, and then press the button when erecting the flip panel, so that the movable pin avoids the edge of the side panel, inserts the fixed pin into the through hole of the edge, and releases the button. The movable pin gets back to the reset position (that is, the pin bar is at the outer end of the slide rail) under the action of the back-moving spring.

Due to the application of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art:

1. Since the utility model is equipped with a driving mechanism, the pin rod is used to drive the movable pin to slide in the inclined slide rail to realize the locking between the movable pin and the pin hole, so that only one button is pressed to complete the alignment. The unlocking process of the box makes the folding and unfolding of the box more convenient and faster.

2. Use the elastic force of the return spring to replace the stretching force formed only by the flexibility of the plastic itself, which makes production and processing more convenient, saves the cost of injection molding and opening molds in the past, and reduces production costs; in addition, the elasticity of the return spring is Inherent, long service life, at the same time, the drive mechanism and the box itself are in a separate structure, which can be replaced when aging and damage occur to avoid waste.

3. The utility model has the advantages of simple structure, easy injection molding and low production cost.
