[0002] With the rapid development of society, more and more products with rod / tubular structures need to achieve connection and assembly functions, such as coat racks, mop handles, storage racks, shoe racks, fishing rods, etc., which can be quickly disassembled and freely assembled. As a result, a large number of connection technologies and connectors have emerged. At present, the connection of rods and tubular objects on the market is mostly achieved by technologies such as buckles, screws, gluing, and welding. Buckle methods often require spring components, which are complex in structure and easy to damage; screw structures have a complicated operation experience, cannot achieve quick disassembly and assembly, and are difficult to rotate and fix; gluing and welding methods are complicated to process and cannot be disassembled and assembled by users. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings in the existing technology, one objective of this utility model is to provide a connector for inserting tubes of a shelf that is simple in structure, easy to operate, and firmly connected.

[0004] Another objective of this invention is to provide a shelf insert assembly having the aforementioned connector for shelf inserts.

[0005] This utility model is achieved through the following technical solution: a connector for a shelf insert tube, comprising a connecting part and an insert part connected to both ends of the connecting part, one end of the insert part being integrally formed with the connecting part, and the other end of the insert part having a mating part integrally formed therewith, the outer diameter of the mating part gradually decreasing from one end to the other end, the insert part having at least one pressing structure, the pressing structure comprising a U-shaped clearance hole and an elastic part respectively formed on the insert part, the surface of the elastic part having a positioning protrusion, the surface of the positioning protrusion having a pressing surface, the U-shaped clearance hole penetrating through the side wall of the insert part, the U-shaped clearance hole being disposed between the insert part and the mating part, so that the elastic part is formed between the insert part and the mating part.

[0006] According to one example of the present invention, the elastic part is in the shape of an elongated sheet, and one end of the elastic part is connected to the end of the U-shaped relief hole near the mating part.

[0007] According to one example of the present invention, the connecting part is ring-shaped.

[0008] According to one example of the present invention, the outer diameter of the connecting portion is larger than the outer diameter of the insertion portion.

[0009] According to one example of the present invention, the axis of the connecting part is collinear with the axes of the insertion part and the mating part.

[0010] The shelf insertion tube assembly according to the present utility model includes the connector for shelf insertion tube as described in any of the above claims;

[0011] Both the first and second tubes are hollow tubes, and their tube walls are provided with positioning through holes that are adapted to the positioning protrusions. The two ends of the connector are respectively inserted into the first and second tubes and fixed by the positioning protrusions and the positioning through holes.

[0012] According to one example of the present invention, the plug portion is connected to the first tube and the second tube in an interference fit.

[0013] According to one example of the present invention, the outer diameter of the mating portion is smaller than the diameter of the first tube and the second tube.

[0014] According to an example of this utility model, the first tube and the second tube are both two oppositely arranged first tubes and second tubes. The two first tubes are connected by multiple longitudinal support rods, which are spaced apart. Each pair of adjacent longitudinal support rods is connected by a transverse support rod. The two second tubes are connected by multiple longitudinal support rods, which are spaced apart. Each pair of adjacent longitudinal support rods is connected by a transverse support rod, so that the first tube, the second tube, the longitudinal support rods, and the longitudinal support rods form the frame of the shelf.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] 1. The connector of this utility model can be used to connect and separate two pipes. By matching the positioning protrusion of the pressing structure with the positioning holes of the two pipes, it is easy to disassemble and assemble and the connection is firm.

[0017] 2. The connector of this utility model has added a mating part at both ends. The outer diameter of the mating part gradually decreases from one end to the other end, so that when the connector is connected to two pipes, the mating part can easily extend into the inside of the pipe first, and finally the insertion part is interference fit with the pipe. This has the advantages of easy and labor-saving installation, and a more secure connection that is not easy to loosen.

[0018] 3. When the connector of this utility model is used to connect two shelving frames, it can be replaced when it is damaged, instead of replacing the existing shelving frame where the spring piece inside the tube is damaged, which would lead to the replacement of the entire frame, thereby reducing replacement costs.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0037] Reference Figures 1 to 5 As shown, a connector for a shelf insert tube includes a connecting part 1 and an insert part 2 connected to both ends of the connecting part 1. One end of the insert part 2 is integrally formed with the connecting part 1, and the other end of the insert part 2 is provided with a mating part 3 integrally formed with it. The axis of the connecting part 1 is collinear with the axes of the insert part 2 and the mating part 3. The outer diameter of the mating part 3 gradually decreases from one end to the other end, so that when the connector is connected to two tubes, the mating part can easily extend into the inside of the tube first, and finally the insert part is interference-fitted with the tube.

[0038] To ensure a secure connection between the connector and the two pipes during assembly, the insertion part 2 is provided with at least one pressing structure 4; that is, the insertion part 2 can have two pressing structures. When two pressing structures are used, they are arranged opposite to each other on the insertion part. Preferably, in this embodiment, one pressing structure 4 is provided on each insertion part 2, provided that the connector and the two pipes are securely assembled. The pressing structure 4 includes a U-shaped clearance hole 40 and an elastic part 41 formed on the insertion part 2. The surface of the elastic part 41 is provided with a positioning protrusion 42, and the surface of the positioning protrusion 42 has a pressing surface 43. The U-shaped clearance hole 40 penetrates the side wall of the insertion part 2 and is located between the insertion part 2 and the mating part 3, so that the elastic part 41 is formed between the insertion part and the mating part.

[0039] According to one example of the present invention, the elastic part 41 is in the shape of a long sheet, and one end of the elastic part 41 is connected to one end of the U-shaped relief hole 40 near the docking part 3, so that the elastic part can be deformed into the insertion part 3 after being pressed by the pressing surface, allowing the insertion part to extend into the connecting tube.

[0040] According to one example of this utility model, the connecting part 1 is ring-shaped, and the outer diameter of the connecting part 1 is larger than the outer diameter of the insertion part 2, so that the connecting tube of the shelf and the connecting piece are limited after assembly, ensuring that the connecting tubes at both ends of the connecting piece are adapted and fixedly connected to the connecting piece.

[0041] In addition, in order to make the overall strength of the connector higher, the connector 1, the insertion part 2, the mating part 3 and the pressing structure 4 are integrated into one structure in this embodiment. It is made of tough material by injection molding. Since the connector is made of tough material, after pressing the pressing surface 43, the elastic part 41 can deform into the insertion part 3. When the pressing surface 43 is not subjected to pressing force, the elastic part 41 deforms to the initial state. Example

[0042] Reference Figures 1 to 5 As shown, the shelf insertion tube assembly includes a connector for shelf insertion tubes as described in any of the above claims; the first tube 5 and the second tube 6 are both hollow tubes, and their tube walls are provided with positioning through holes 7 that are adapted to the positioning protrusions 42. The opposite ends of the connector are respectively inserted into the first tube 5 and the second tube 6, and fixed to the positioning through holes 7 by the positioning protrusions 42. The outer diameter of the mating part 3 is smaller than the diameter of the first tube 5 and the second tube 6, so that the mating part 3 can be more easily inserted into the first tube 5 and / or the second tube 6 first, and finally the insertion part 2 is connected to the first tube 5 and the second tube 6 with an interference fit.

[0043] According to an example of this utility model, the first tube 5 and the second tube 6 are two oppositely arranged first tubes 5 and second tubes 6. The two first tubes 5 are connected by multiple longitudinal support rods 50, which are spaced apart. Each pair of adjacent longitudinal support rods 50 is connected by a transverse support rod 51. The two second tubes 6 are connected by multiple longitudinal support rods 60, which are spaced apart. Each pair of adjacent longitudinal support rods 60 is connected by a transverse support rod 61, so that the first tube 5, the second tube 6, the longitudinal support rods 50 and the longitudinal support rods 60 form the frame 8 of the shelf.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
