Description

Technical Field

[0001] The utility model belongs to the technical field of telescopic rods and relates to a telescopic rod body connector structure. Background Art

[0002] The principle of the telescopic rod is a retractable hollow cylindrical rod made of metal strip or plastic sheet. The characteristic is that the metal strip or plastic sheet is pre-shaped into an elastic curled layer with memory function which is smaller than the outer diameter of the rod body, so that it has a self-tightening function, so that the curled layer always has elastic potential energy to exert pressure on the telescopic rod. The extension and retraction mechanism can generally choose to use "electric push rod", "electro-hydraulic push rod", "pneumatic push rod" and "hydraulic push rod". If it is installed horizontally, the force is not large, the stroke is long, and a guide rail can be installed.

[0003] When the telescopic rod is installed, its end needs to be connected through a special connector so that the telescopic rod can be rotated to adjust the rotation position. However, the existing rotating structures are directly supported and rotated by a rotating shaft rod and a bearing. Such a structure has two problems. First, the bearing is directly exposed to the outside, and dust is easily entered into the rotating part. Second, it is supported by a single rotating rod, and the strength of the rod is limited. When the rod is subjected to force on both sides, it will cause the rod to rotate and deviate, thereby affecting the rotation of the rod. Summary of the invention

[0004] The purpose of the utility model is to provide a telescopic rod body connecting head structure to solve the problems raised in the above background technology.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] The telescopic rod body connecting head structure includes a fixed end head, a connecting end head, a dust cover, a fixed plate body, a side support arm and a support guide wheel. One end of the fixed end head is movably connected with a bearing seat. Two side support arms are arranged on the side positions of the bearing seat. The two side support arms are symmetrically arranged about the bearing seat. A dust cover is arranged between the two side support arms. A guide wheel plate is arranged at the bottom of the two side support arms. A support guide wheel is movably installed on the inner side of the guide wheel plate through a rotating shaft. A guide wheel groove is opened on the outer wall surface of the fixed end head, and the support guide wheel slides inside the guide wheel groove.

[0007] In the above-mentioned telescopic rod connecting head structure, a fixing plate is provided at one end of the fixing end, and a fixing hole is provided inside the fixing plate.
