Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a valve packaging box structure. Background Art

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and regulate. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, angle valves, etc. It is mainly used for installation in conveying pipelines or household life and is a part used to cut off or allow the flow of media.

[0003] During the transportation of valves, it is usually necessary to package the valves to prevent damage caused by impact during transportation. Traditionally, for the packaging of valves, EPE is usually placed in the box body, and the EPE needs to be provided with a placement groove corresponding to the shape of the valve. The placement groove and the EPE can play a role in limiting and protecting the valve.

[0004] Although the method of using EPE and the placement groove can protect the valve, when the packaging box needs to package valves of other valve types, since the shapes and sizes of different types of valves are not the same, it is also necessary to design corresponding-shaped EPE for protection. The packaging box cannot protect according to the shape and size of the valve, and the scope of use of the packaging box is relatively limited. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a valve packaging box structure in view of the defects and deficiencies of the prior art.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A valve packaging box structure includes a bottom cover, a receiving cavity opened on the bottom cover, a top cover disposed on the bottom cover and in clearance fit with the bottom cover, and further includes two adjusting plates movably disposed on the bottom cover within the receiving cavity for laterally moving within the receiving cavity when driven by an external force, a plurality of upper mating slots respectively opened on the two adjusting plates, two gap partitions respectively disposed at the front and rear ends of the two adjusting plates, and a plurality of mating card slots opened at the lower ends of the gap partitions for clearance fit with the mating slots. The two adjusting plates are arranged along the width direction of the bottom cover, the two gap partitions are arranged along the length direction of the bottom cover, the plurality of mating slots are equidistantly arranged along the length direction of the adjusting plate, the mating slots are opened on the adjusting plate from top to bottom, the plurality of mating card slots are equidistantly arranged along the length direction of the gap partition, and the mating card slots are opened on the gap partition from bottom to top. Two transverse waist holes are respectively opened at the front and rear ends of the bottom cover, the two transverse waist holes communicate with the receiving cavity, sliding rods are respectively opened at the front and rear ends of the two adjusting plates, the sliding rods are in clearance fit with the transverse waist holes, the two transverse waist holes are arranged along the length direction of the bottom cover, at least four positioning card holes are opened on the top cover, the positioning card holes are in clearance fit with the sliding rods, the positioning card holes are opened at the lower end of the top cover from bottom to top, and the four positioning card holes are equidistantly arranged on the top cover.

[0007] Further improvement is: Flexible contact layers are respectively disposed on the side end faces of the two adjusting plates and the end faces of the two gap partitions.

[0008] Further improvement is: The flexible contact layer is a rubber layer or a sponge layer.

[0009] Further improvement is: A sealing protrusion is disposed on the side end face of the bottom cover, the sealing protrusion is an arc-shaped protrusion, an inclined contact surface is disposed at the lower end of the top cover, and a sealing card slot for snap-fitting connection with the sealing protrusion is opened on the top cover, and the sealing card slot is an arc-shaped card slot.

[0010] Further improvement is: Both the adjusting plate and the gap partition are made of cardboard or acrylic board.

[0011] Further improvement is: The sliding rod is a plastic rod or an acrylic rod.

[0012] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: When the packaging box needs to package valves of other valve types, since the shapes and sizes of different types of valves are not the same, first place the valve in the receiving cavity of the bottom cover. Then, horizontally drive the two adjusting plates to move horizontally in the receiving cavity by hand, and drive the sliding rods at the front and rear ends to move together in the horizontal waist holes. When the two adjusting plates are located on the left and right sides of the valve, slightly adjust the position of the sliding rods to correspond to the positioning card holes of the top cover, so that when the top cover covers the bottom cover, the positioning card holes are engaged with the sliding rods, thereby limiting the position of the sliding rods and further restricting the position of the adjusting plates in the bottom cover. Then, install the two gap partitions on the adjusting plates, make the two gap partitions located on the front and rear sides of the valve, and cooperate the matching card slots on the gap partitions with the matching slots on the adjusting plates, thereby fixing the position of the gap partitions on the adjusting plates to limit the periphery of the valve and prevent the valve from colliding in the receiving cavity during transportation. The packaging box can protect according to the shape and size of the valve, and has a wide range of uses.

[0013] Further effect: When the adjusting plates and the gap partitions limit the left and right sides and the front and rear sides of the valve respectively, the flexible contact layer reduces the impact between the valve and the adjusting plates and the gap partitions, thereby protecting the valve and reducing the occurrence of bumps.

[0014] Further effect: During the process of installing the top cover on the bottom cover, the inclined contact surface first contacts the arc-shaped protrusion. As the two come into contact, the lower end surface of the top cover expands outwards. As the top cover descends on the bottom cover, until the sealing protrusion is engaged with the sealing card slot, at this time the top cover resets and no longer expands outwards. The cooperation between the sealing protrusion and the sealing card slot improves the installation stability of the top cover on the bottom cover. Description of the Drawings
