Description

Technical Field

[0001] The utility model belongs to the technical field of shelves, and specifically relates to a wooden connector for a storage rack. Background Art

[0002] In recent years, paper tube storage racks have been increasingly widely used, and are widely used in freight transportation, exhibitions, and furniture. Paper tube storage racks have the characteristics of environmental protection and easy recycling. Light weight, multiple disassembly and assembly, and strong bearing capacity are the core characteristics of paper tube storage racks. One-time molding, environmental protection, recyclability, and modular installation are the keys for enterprises to reduce costs. 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, which need to be removed separately for treatment during recycling, which is very inconvenient; secondly, the friction between the plastic connectors and the paper tubes is insufficient, and they are prone to looseness or falling off. Summary of the Invention

[0003] The purpose of the utility model is to provide a wooden connector for a 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:

[0005] A wooden connector for a storage rack, which is applied to the connection of paper tubes, includes: a central part and a plug-in part.

[0006] The central part is provided with a butt joint surface and a positioning protrusion. There are at least two butt joint surfaces, and the positioning protrusion is arranged around the butt joint surface.

[0007] The plug-in part includes a butt joint end and a plug end. The butt joint end is bonded to the butt joint surface, and the plug end is used to insert into the paper tube. The number of plug-in parts is the same as the number of butt joint surfaces on the central part.

[0008] Further, it also includes a pin column. The butt joint surface is provided with a first pin hole, the butt joint end is provided with a second pin hole, one end of the pin column is matched with the first pin hole, and the other end of the pin column is matched with the second pin hole.

[0009] Further, the butt joint end and the butt joint surface are bonded with glue, and both ends of the pin column are bonded with the first pin hole and the second pin hole respectively with glue.

[0010] Further, the central part, the plug-in part, and the pin column are all made of beech, fir, birch, pine or bamboo wood.

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

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

[0013] Furthermore, the plug-in 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 wooden connector of the storage rack is used to position the docking end of the plug-in 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 this connector is stable and convenient for recycling. Description of the Drawings

[0020] 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.

[0021] As Figures 1 to 2 shown, a wooden connector for a storage rack, which is applied to the connection of paper tubes, includes: a central part 1, a plug-in part 2, and a pin post 3.

[0022] The central part 1 is provided with a docking surface 11 and a positioning protrusion 12. There are at least two docking surfaces 11, and the positioning protrusion 12 is arranged around the docking surface 11.

[0023] 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.

[0024] 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 post 3 is matched with the first pin hole 13, and the other end of the pin post 3 is matched with the second pin hole 23.

[0025] The docking end 21 and the docking surface 11 are bonded with glue, and both ends of the pin 3 are bonded with the first pin hole 13 and the second pin hole 23 with glue.

[0026] The central part 1, the insertion part 2, and the pin 3 are all made of beech, fir, birch, pine, or bamboo and wood.

[0027] The width of the positioning protrusion 12 is 3 - 5 mm. This prevents the positioning protrusion 12 from being damaged due to being too narrow.

[0028] 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. The two 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 insertion part 2 and the central part of the cuboid form a connecting piece with three or more connections.

[0029] The insertion part 2 is in the shape of a boss, and the cross-sectional area from its docking end 21 to the plug end 22 gradually decreases. This facilitates interference fit and improves the stability of the connection.

[0030] During installation, apply glue on the docking surface 11 on the central part 1 and the docking end 21 of the insertion 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 protrusion 12 provided on the central part 1 is used to position the docking end 21 of the insertion part 2. After the insertion part 2 is bonded to the central part 1, the positioning protrusion 12 axially restricts the insertion to prevent the docking part from deflecting. According to the needs of assembly, there are two, three, four, five, or six corresponding sets of the insertion part 2 and the docking surface 11. Insert the plug end 22 of the insertion part 2 into the end of the paper tube to form a stable storage rack structure. During recycling, the connecting piece and the paper tube are crushed together to make pulp, which can be made into paper tubes or other paper products again.
