Description

Technical Field

[0001] The utility model relates to the technical field of clothes hangers, and particularly relates to a telescopic frame reinforcing connecting rod. Background Art

[0002] As shown in the existing clothes hanger Figure 1 During the process of hanging clothes, the stress point is concentrated at the top hinge position A of the mounting frame and the telescopic frame. However, the connecting rod at the stress point of the existing clothes hanger is not structurally strengthened. A conventional hollow tube is used. After a period of time, due to the back-and-forth pulling of the telescopic frame or the heavy clothes dried for a long time, the connecting hole of the connecting rod at the hinge position A rubs against the rotating shaft, resulting in cracking of the connecting hole. As shown in Figure 2 This causes the connecting rod to directly disengage from the rotating shaft at the hinge position A, damaging the telescopic frame and making it unable to be used normally. Therefore, how to solve the problem of easy cracking of the connecting hole at the hinge position A on the telescopic frame of the existing clothes hanger has become a problem to be solved currently. Content of the Utility Model

[0003] The purpose of the utility model is to provide a telescopic frame reinforcing connecting rod to solve at least one of the above problems existing in the prior art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A telescopic frame reinforcing connecting rod includes a telescopic frame. The telescopic frame includes a stress-bearing flat tube and a first rotating shaft. Multiple reinforcing plates are arranged between two side plates on the length side of the rectangular cross-section of the stress-bearing flat tube. The multiple reinforcing plates are arranged in parallel along the length direction of the stress-bearing flat tube. First connecting holes are provided on both the two side plates and the reinforcing plates. The first rotating shaft sequentially passes through the corresponding first connecting holes.

[0006] In this technical solution, since multiple reinforcing plates are arranged between two side plates on the length side of the rectangular cross-section of the stress-bearing flat tube, the multiple reinforcing plates are arranged in parallel along the length direction of the stress-bearing flat tube, and first connecting holes are provided on both the two side plates and the reinforcing plates, the first rotating shaft can be connected to at least four connecting holes. Compared with the existing structural design of a hollow flat tube, the first rotating shaft is only connected to two connecting holes, and the connecting holes are prone to cracking. In this technology, the first rotating shaft can be connected to at least four connecting holes, which can significantly improve the structural strength at the connecting hole. The four first connecting holes can share the stress, thus solving the problem of wear and cracking of the connecting hole caused by the long-term friction between the two connecting holes and the rotating shaft.

[0007] Further, in order to provide a stress-bearing flat tube with multiple reinforcing plates integrally formed, the multiple reinforcing plates are integrally formed inside the stress-bearing flat tube.

[0008] Further, in order to provide a force-bearing flat tube with a nested structure, a first inner flat tube is nested inside the force-bearing flat tube, and the positions corresponding to the side plates on the first inner flat tube are reinforcing plates.

[0009] Further, in order to provide a force-bearing flat tube with a multi-layer nested structure, a second inner flat tube is nested inside the first inner flat tube, and the positions corresponding to the side plates on the second inner flat tube are reinforcing plates.

[0010] Further, in order to enhance the structural strength at the second connection holes, a second rotating shaft is further included. Second connection holes are provided on both side plates and the reinforcing plates, and the second rotating shaft sequentially passes through the corresponding second connection holes.

[0011] Further, in order to enhance the structural strength at the third connection holes, a third rotating shaft is further included. Third connection holes are provided on both side plates and the reinforcing plates, and the third rotating shaft sequentially passes through the corresponding third connection holes.

[0012] Further, for the convenience of installation, the first rotating shaft, the second rotating shaft, and the third rotating shaft are all made of metal rivets.

[0013] The beneficial effects of the present utility model are as follows: In this technical solution, since multiple reinforcing plates are provided between the two side plates on the long side of the rectangular cross-section of the force-bearing flat tube, and the multiple reinforcing plates are arranged in parallel along the length direction of the force-bearing flat tube, and first connection holes are provided on both side plates and the reinforcing plates, the first rotating shaft can be connected to at least four connection holes. Compared with the existing structural design of a hollow flat tube, in which the first rotating shaft is only connected to two connection holes and the connection holes are prone to cracking, the first rotating shaft in this technology can be connected to at least four connection holes, which can significantly improve the structural strength at the connection holes. The four first connection holes can share the force, thus solving the problem of wear and cracking of the connection holes caused by long-term friction between the two connection holes and the rotating shaft.
