Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a connection structure and a clothes hanger. Background Art

[0002] Clothes hangers are common furniture in daily life. To meet the needs of diverse usage scenarios, modular hangers that can be assembled into various forms have appeared in the prior art. Modular hangers are usually assembled with pipe fittings as the main body, and adjacent pipe fittings can usually be connected by threaded fittings, and further assembled into three-dimensional hangers through three-dimensional connectors such as tees and crosses. Obviously, if the connection between pipe fittings is achieved by threaded fittings, adjacent pipe fittings can be directly assembled manually by twisting, but pipe fittings cannot be enclosed to form a closed shape by threaded fittings alone. At most, they can only form a U-shaped frame. If a closed loop is to be formed, it is also necessary to use components such as shrink tube lock screws and external tools to achieve assembly, and it is impossible to completely achieve hanger assembly without external tools.

[0038] As a preferred embodiment, a groove 13 is formed at one end of the connecting piece 1 for connecting with the second pipe fitting 3, and a clamping ring 31 protruding toward the axis is formed inside the second pipe fitting 3. During the process of inserting the connecting piece 1 into the second pipe fitting 3, when the clamping ring 31 is embedded in the groove 13, the connecting piece 1 and the second pipe fitting 3 reach a stable connection state. Through the cooperation of the clamping ring 31 and the groove 13, the connection between the connecting piece 1 and the second pipe fitting 3 in the stable connection state is made more secure.

[0039] As a preferred embodiment, the connecting member 1 is a hollow structure, and the spring sheet 11 is formed by dividing the connecting member 1 by setting a spring sheet groove 111, that is, the spring sheet 11 and the connecting member 1 are an integrated structure. Figure 6-7 In the embodiment shown, each spring piece 11 is formed by two spring piece grooves 111 extending from the end of the connecting member 1 along the length direction of the connecting member 1. Figure 8 In the illustrated embodiment, the spring sheet groove 111 is arc-shaped, and one spring sheet groove 111 can directly separate the spring sheets 11 on the connecting member 1 .

[0040] In addition, in other embodiments of the present invention, multiple spring clips 11 can be provided, the number of connecting ports 21 on the first tube 2 is the same as the number of spring clips 11 on the connecting member 1, and the multiple spring clips 11 on the connecting member 1 are distributed around the connecting member 1 at equal intervals (for example, when two spring clips 11 are provided, the two spring clips surround the connecting member 1 and are distributed at an interval of 180°; when three spring clips 11 are provided, the three spring clips surround the connecting member 1 and are distributed at an interval of 120°; when four spring clips 11 are provided, the four spring clips surround the connecting member 1 and are distributed at an interval of 90°, and so on).

[0041] As a preferred embodiment, a plurality of bosses 14 are provided on both sides of the slot 13, and the bosses 14 can realize an interference fit between the connector 1 and the second pipe fitting 3 while saving the material of the connector 1 (so that the main body of the connector 1 does not need to have an outer diameter satisfying the interference fit).

[0042] In order to improve the convenience of inserting the connecting piece 1 into the first pipe fitting 2 and the second pipe fitting 3, a first chamfer 101 is formed at one end of the connecting piece 1 for connecting to the first pipe fitting 2, and a second chamfer 102 is formed at one end of the connecting piece 1 for connecting to the second pipe fitting 3. The first chamfer 101 and the second chamfer 102 both form a conical surface at the end portion that gradually reduces the outer diameter of the connecting piece 1, thereby facilitating the insertion of the connecting piece 1.

[0043] In the connection structure of the present invention, the connecting piece 1 and the first pipe fitting 2 can be directly inserted and connected, and the connection protrusion 12 is embedded in the connection port 21 to ensure the stable connection between the connecting piece 1 and the first pipe fitting 2, and the connecting piece 1 and the second pipe fitting 3 can be directly inserted and connected through an interference fit, thereby realizing tool-free assembly of the connection structure.

[0044] like Fig. 9 As shown, the utility model also provides a clothes hanger. The clothes hanger further includes a third pipe fitting 4 on the basis of the aforementioned connection structure. In one embodiment, in order to enable the third pipe fittings 4 to be connected with each other by threaded fitting, one end of the third pipe fitting 4 is formed with an external thread, and the other end is formed with a threaded hole; the end of the first pipe fitting 2 away from the connecting member 1 has an external thread or is formed with a threaded hole, so that the first pipe fitting 2 and the third pipe fitting 4 can be connected with each other by threaded fitting; the end of the second pipe fitting 3 away from the connecting member 1 has an external thread or is formed with a threaded hole, so that the second pipe fitting 3 and the third pipe fitting 4 can also be connected with each other by threaded fitting.

[0045] In another embodiment, the clothes hanger also includes a threaded connection component, which can be a single stud screw (in this case, threaded holes need to be provided on the first pipe fitting 2, the second pipe fitting 3, the third pipe fitting 4 and the three-dimensional connector), or an assembly consisting of a stud screw and a pipe union nut (the pipe union nut is used to be installed on the end of the pipe fitting, so that there is no need to open a threaded hole on the end of the pipe fitting). The stud screw and the pipe union nut are both products of the prior art, and there are already a variety of specific structural embodiments of them in the prior art; each third pipe fitting 4, the first pipe fitting 2 and the third pipe fitting 4, and the second pipe fitting 3 and the third pipe fitting 4 are all threadedly connected by installing a threaded connection component; similarly, each connection end of the three-dimensional connector is threadedly connected to the first pipe fitting 2, the second pipe fitting 3 and the third pipe fitting 4 respectively through a threaded connection component.

[0046] A closed ring or frame structure can be formed by manually assembling the connector 1, the first pipe 2, the second pipe 3 and the third pipe 4 without the aid of external tools. By further introducing three-dimensional connectors such as three-way connectors and four-way connectors (it can be understood that the three-dimensional connector has more than three connecting ends, each of which is formed with an external thread or a threaded hole, and the three-dimensional connector can be threadedly connected to the first pipe 2, the second pipe 3 and the third pipe 4), as well as an optionally introduced threaded connection component, a three-dimensional clothes hanger can be assembled, which can be manually assembled without the aid of external tools.

[0047] The connection structure provided by the utility model can be manually assembled without external tools, which is more convenient than the traditional pipe connection method. The hanger provided by the utility model further introduces three-dimensional connecting parts on the basis of utilizing the connection structure of the utility model, thereby realizing manual assembly of the entire hanger without external tools.

[0048] The above-mentioned embodiments only express the implementation methods of the utility model, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
