Description

Technical Field

[0001] The utility model belongs to the technical field of shelves, and specifically relates to an environment-friendly storage rack. Background Art

[0002] In recent years, the application of paper tube storage racks has become more and more extensive, and they are widely used in freight transportation, exhibitions, and furniture. Paper tube storage racks have the characteristics of environmental protection and easy recycling. Lightweight, capable of being disassembled and assembled repeatedly for multiple times, and strong in bearing force are the core characteristics of paper tube storage racks. One-time forming, environmental protection, recyclability, and modular installation have become the key to cost reduction for enterprises. Square paper tubes have been applied to the display field for more than ten years, and there are a large number of application cases in packaging exhibitions, tobacco and alcohol exhibitions, and book culture festivals. However, the inventor of this application found in practice that: most of the connectors of paper tube storage racks are made of injection-molded plastic connectors. When recycling, the plastic connectors need to be removed and treated separately, which is very inconvenient; secondly, the frictional force between the plastic connectors and the paper tubes is insufficient, and they are prone to looseness or detachment. Summary of the Invention

[0003] The purpose of the utility model is to provide an environment-friendly storage rack that is convenient for recycling in view of the above-mentioned deficiencies of the prior art.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0005] An environment-friendly storage rack is applied to the connection of paper tubes and includes: paper tubes, support plates, and connectors. The interior of the paper tube is a hollow structure; the support plate is placed above the paper tube.

[0006] The connector includes a central part and a plug-in part. The central part is provided with a docking surface and a positioning protrusion, and the positioning protrusion is arranged around the docking surface. The plug-in part includes a docking end and a plug end. The docking end is bonded to the docking surface, and the plug end is used for inserting into the paper tube. The number of plug-in parts is the same as the number of docking surfaces on the central part. Among them, the plug end is inserted into the end of the paper tube, so that a plurality of the paper tubes are connected to each other to form a frame structure.

[0007] Further, the connector further includes a pin. The docking surface is provided with a first pin hole, the docking end is provided with a second pin hole, one end of the pin is matched with the first pin hole, and the other end of the pin is matched with the second pin hole.

[0008] Further, the docking end and the docking surface are bonded with glue, and both ends of the pin are bonded with the first pin hole and the second pin hole with glue respectively.

[0009] Further, the central part, the plug-in part, and the pin are all made of beech, fir, birch, pine, or bamboo.

[0010] Further, the support plate is made of wood board, cardboard or density board.

[0011] Further, the width of the positioning protrusion is 3 - 5 mm.

[0012] Further, the central part is in the shape of a cube or a cuboid.

[0013] Further, the insertion part is in the shape of a boss, and the cross-sectional area gradually decreases from the docking end to the plug end.

[0014] The beneficial effects of the present utility model are as follows: The positioning protrusion provided on the central part of the connecting member of the environmental protection storage rack is used to position the docking end of the insertion part, which is convenient for assembly and can prevent the deflection of the docking part. The storage rack structure composed of paper tubes connected by using this connecting member is stable and convenient for the recycling of all materials. Description of the Drawings

[0022] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. Embodiment

[0023] As Figures 1 to 6 shown, an environmental protection storage rack, which is applied to the connection of paper tubes 4, includes: paper tubes 4, support plates 5 and connecting members.

[0024] As Figure 6As shown, the inside of the paper tube 4 has a hollow structure. The support plate 5 is placed above the paper tube 4, and the support plate 5 is made of wood board, cardboard, or density board.

[0025] As Figures 2 - 3 shown, the connecting piece includes a central part 1 and a plug-in part 2. The central part 1 is provided with a docking surface 11 and a positioning projection 12, and the positioning projection 12 is arranged around the docking surface 11. The width of the positioning projection 12 is 3 - 5 mm. The central part 1, the plug-in part 2, and the pin 3 are all made of beech, fir, birch, pine, or bamboo wood. As Figure 4 shown, the central part 1 is in the shape of a cube; the central part 1 can also be set in the shape of a cuboid, and both ends of the cuboid are used to insert into the paper tube, the docking surface 11 is arranged in the middle of the cuboid, and the plug-in part 2 and the central part of the cuboid form a connecting piece with three or more connections.

[0026] As Figure 5 shown, the plug-in part 2 includes a docking end 21 and a plug end 22. The docking end 21 is bonded to the docking surface 11, and the plug end 22 is used to insert into the paper tube 4. The number of the plug-in parts 2 is the same as the number of the docking surfaces 11 on the central part 1. Among them, the plug end 22 is inserted into the end of the paper tube 4, so that multiple paper tubes 4 are connected to each other to form a frame structure. The plug-in part 2 is in the shape of a frustum of a cone, and the cross-sectional area from its docking end 21 to the plug end 22 gradually decreases.

[0027] The connecting piece further includes a pin 3. The docking surface 11 is provided with a first pin hole 13, the docking end 21 is provided with a second pin hole 23, one end of the pin 3 is matched with the first pin hole 13, and the other end of the pin 3 is matched with the second pin hole 23.

[0028] The docking end 21 and the docking surface 11 are bonded by glue, and both ends of the pin 3 are bonded to the first pin hole 13 and the second pin hole 23 by glue respectively.

[0029] During installation, apply glue on the docking surface 11 on the central part 1 and the docking end 21 of the plug-in part 2, and also apply glue on the pin 3. Insert the pin 3 into the first pin hole 13 and the second pin hole 23. The positioning projection 12 provided on the central part 1 is used to position the docking end 21 of the plug-in part 2. After the plug-in part 2 is bonded to the central part 1, the positioning projection 12 axially restricts the plug-in, preventing the docking part from deflecting. According to the needs of assembly, there are two, three, four, five, or six corresponding plug-in parts 2 and docking surfaces 11. Insert the plug end 22 of the plug-in part 2 into the end of the paper tube 4 to form a stable storage rack frame structure. After the frame structure is assembled and formed, place the support plate 5 above the paper tube.

[0030] During recycling, the connecting piece and the paper tube 4 are shredded together to make pulp, which can be made into the paper tube 4 or other paper products again.
