[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example

[0026] See Figures 1 to 3 The figure shows a tubular quick-positioning connection structure comprising a connecting tube 1 and two tightening control tubes 2 disposed at either end of the connecting tube. The tightening control tubes are provided with limiting protrusions 3 on their inner walls. In this embodiment, both the connecting tube and the tightening control tube are made of plastic. The limiting protrusions primarily limit the position of the annular pressure plate, thereby driving the annular pressure plate to move when the tightening control tubes rotate.

[0027] In actual use, the tightening control cylinder is provided with an annular pressure plate 5 with a notch 4. The inner edge of the annular pressure plate is bent downward to form a plurality of pressure claws 6. The surface of the annular pressure plate abuts against the limiting convex ring. To ensure the stability and reliability of the claws, the annular pressure plate and pressure claws are made of unfinished steel sheets. In this embodiment, the notch is provided in the annular pressure plate, so that the annular pressure plate has a certain amount of shrinkage space, ensuring the smoothness and reliability of the subsequent clamping operation.

[0028] At the same time, trumpet-shaped guide parts 7 are provided on the inner walls of both ends of the connecting tube; in this embodiment, the trumpet-shaped guide parts are mainly used to guide the pressing claws and gradually clamp the ends of the pressing claws toward the middle.

[0029] During assembly, the tightening control cylinder rotates and connects within the connecting cylinder, driving the annular pressure plate downward toward the connecting cylinder. The pressure claw, guided by the trumpet-shaped guide, clamps toward the center. In actual use, the pressure claw forms an angle of 135-150 degrees with the annular pressure plate. The inclination angle of the trumpet-shaped guide matches that of the pressure claw; the pressure claw adheres to and moves along the trumpet-shaped guide.

[0030] In actual use, the outer ends of the connecting tube are provided with external threads 8, and the inner wall of the tightening control tube is provided with internal threads 9. During assembly, the tightening control tube is threadedly connected to the end of the connecting tube. This threaded connection can improve the tightening operation of the tightening control tube and the connecting tube.

[0031] Furthermore, the outer wall of the tightening control cylinder is provided with anti-slip grooves 10, which can improve the effectiveness and stability of the tightening operation.

[0032] When in use, the pipe or rod is passed through the tightening control cylinder and the end is extended into the connecting cylinder. The tightening control cylinder is rotated, and the tightening control cylinder moves horizontally on the connecting cylinder and drives the annular pressure piece with a notch to move horizontally. The pressure claw gradually shrinks toward the center under the action of the trumpet-shaped guide part and abuts against the surface of the pipe or rod to achieve a fixed connection.

[0033] The utility model has positive effects: the structure of the utility model is reasonably set up, which is not only convenient to operate, but also can ensure the stability and reliability of the connection through the annular pressure piece with a notch and the pressure claw. At the same time, it also facilitates the disassembly and assembly operations, improves the efficiency of the disassembly and assembly operations, and has strong applicability and good practicality.

[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0035] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
