Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy pipe equipment, in particular to a quick-detachable aluminum alloy pipe. Background Art

[0002] Aluminum alloy pipe is a seamless non-ferrous metal pipe made by extruding alloy aluminum. Aluminum alloy pipe has many excellent properties, including light weight, corrosion resistance, formability, strength, machinability, surface treatment, conductivity, easy processing, non-toxicity, non-magnetism, weldability, thermal conductivity, no low-temperature brittleness, regeneration and reflectivity. These properties make aluminum alloy pipe widely used in modern industry.

When the first limiting hoop and the second limiting hoop are locked, the staff can adjust the positioning angle of the positioning shaft at any time to facilitate the subsequent limiting of the positioning slot.

[0010] Preferably, the lower end surface of the hexagonal threaded sleeve is threadedly connected to the threaded barrel, and the hexagonal threaded sleeve can be limited by the threads of the two sets of combined threaded barrels, thereby improving the stability of locking the aluminum alloy tube.

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-4 The present invention provides an embodiment of a quick-detachable aluminum alloy tube, comprising two sets of aluminum alloy tubes 8 fitted together, a first limiting hoop 3 for limiting position is provided at the interface between the two sets of aluminum alloy tubes 8, and a guide pin 2 for guiding is fixedly provided on the lower end surface of the first limiting hoop 3.

[0022] A second limiting hoop 9 is hinged to the bottom end of the first limiting hoop 3 through a guide pin 2, and a sealing guard plate 10 is provided inside the first limiting hoop 3 and the second limiting hoop 9. A limiting sleeve 1 is provided at the center of the lower end surface of the second limiting hoop 9, and a threaded rotating cylinder 6 is provided at the center of the upper end surface of the first limiting hoop 3 and the second limiting hoop 9, and a positioning slot 4 is provided on the inner end surface of the threaded rotating cylinder 6. A positioning card groove 7 is provided near the side of the upper end surface of the first limiting hoop 3 and the second limiting hoop 9;

[0023] The limiting device 5 is connected to the upper end surface of the aluminum alloy tube 8 through the threaded rotating cylinder 6 and then threadedly slidably.

[0024] The limiting device 5 includes a hexagonal threaded sleeve 54 for support, a supporting swivel seat 56 is fixedly provided at the center of the upper end surface of the hexagonal threaded sleeve 54, and a fixed clamping shaft 55 is fixedly provided at the center of the inner end surface of the hexagonal threaded sleeve 54, the upper end surface of the supporting swivel seat 56 is rotatably clamped with a fixed rotating plate 51, and a limiting clamping shaft 52 is provided at the center of the lower end surface of the fixed rotating plate 51, and two sets of positioning plug-in shafts 53 are provided at the lower end surface of the fixed rotating plate 51.

[0025] The cross-sections of the limiting clamping shaft 52 and the supporting rotating seat 56 are both T-shaped, and the fixed rotating plate 51 is rotatably connected with the supporting rotating seat 56 through the limiting clamping shaft 52. When the first limiting hoop 3 and the second limiting hoop 9 are locked, the staff can adjust the positioning angle of the positioning plug-in shaft 53 at any time to facilitate the subsequent limiting of the positioning slot 7.

[0026] The lower end surface of the hexagonal threaded sleeve 54 is threadedly connected to the threaded rotating cylinder 6. The hexagonal threaded sleeve 54 can be limited by the threads of the two sets of combined threaded rotating cylinders 6, thereby improving the stability of locking the aluminum alloy tube 8.

[0027] The fixed clamping shaft 55 is slidably plugged into the interior of the threaded rotating cylinder 6 through the positioning slot 4. The sliding limit of the positioning slot 4 and the threaded rotating cylinder 6 can improve the accuracy of subsequent connection positioning.

[0028] The first limiting hoop 3 and the second limiting hoop 9 are fixedly connected to the positioning plug shaft 53 through the positioning slots 7. After the first limiting hoop 3 and the second limiting hoop 9 are locked, the two sets of positioning slots 7 can further improve the stability of the first limiting hoop 3 and the second limiting hoop 9 on the aluminum alloy tube 8 by limiting with the positioning plug shaft 53.

[0029] Working principle: When in use, the staff can position the two sets of aluminum alloy tubes 8 that are butt-jointed on the fixture, and then align the opened first limiting hoop 3 and the second limiting hoop 9 to the interface of the aluminum alloy tube 8. After the positioning is completed, the first limiting hoop 3 and the second limiting hoop 9 clamp the aluminum alloy tube 8 to limit the two sets of threaded rotating cylinders 6 to be coaxial. Then, the hexagonal threaded sleeve 54 can be limited to the outside of the two sets of threaded rotating cylinders 6. After the limitation is completed, the hexagonal threaded sleeve 54 can be rotated by an external tool so that the hexagonal threaded sleeve 5 4 can limit the two sets of threaded rotating cylinders 6. When the hexagonal threaded sleeve 54 moves downward, it can synchronously drive the two sets of positioning plug shafts 53 to move downward. When the hexagonal threaded sleeve 54 moves downward to the limit, the two sets of positioning plug shafts 53 can be inserted into the interior of the positioning card slot 7, thereby performing dual positioning of the first limiting hoop 3 and the second limiting hoop 9. At the same time, when the first limiting hoop 3 and the second limiting hoop 9 lock the aluminum alloy tube 8, the sealing guard plate 10 is made of a sealing elastic material, which can effectively improve the sealing performance at the interface of the aluminum alloy tube 8 and prevent subsequent leakage.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
