Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and in particular to a folded pipe. Background Technology

[0002] With the development of technology, more and more people have purchased vacuum cleaners for their homes. Most existing vacuum cleaners use rigid tubing to connect the vacuum head and the vacuum cleaner handle. Rigid tubing cannot be folded and is not easy to store. If flexible hoses are used instead of rigid tubing, they can be folded and stored easily, but the flexible hoses can be bent at will, which will cause the vacuum cleaner to malfunction.

[0003] For the reasons mentioned above, it is necessary to improve the existing technology. Utility Model Content

[0008] The second pipe fitting includes a second inner pipe and a second protective pipe sleeved outside the second inner pipe;

[0009] A pivoting mechanism includes a first pivoting part, a second pivoting part, and a pivot connecting the first pivoting part and the second pivoting part. The pivot can drive the first pipe fitting and the second pipe fitting to form a parallel or horizontal state. The first pivoting part has a first pipe opening communicating with the first inner pipe, and the second pivoting part has a second pipe opening communicating with the second inner pipe. A pipe sleeve is fixedly installed in the first pipe opening and the second pipe opening. The pipe sleeves on both sides are surrounded by flanges that are respectively pressed by the first pipe opening and the second pipe opening. The pipe sleeves are connected by a flexible pipe.

Detailed Implementation

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0022] Please see Figure 1-4 The present invention provides a folding tube, including a first tube 1, the first tube 1 including a first inner tube 10 and a first protective tube 11 sleeved outside the first inner tube 10;

[0023] The second pipe fitting 2 includes a second inner pipe 20 and a second protective pipe 21 sleeved outside the second inner pipe 20;

[0024] The pivoting mechanism 3 includes a first pivoting part 30, a second pivoting part 31, and a pivot 32 connecting the first pivoting part 30 and the second pivoting part 31. The pivot 32 can drive the first pipe fitting 1 and the second pipe fitting 2 to form a parallel or horizontal state. The first pivoting part 30 has a first pipe opening 300 communicating with the first inner pipe 10. The second pivoting part 31 has a second pipe opening 301 communicating with the second inner pipe 20. The first pipe opening 300 and the second pipe opening 301 are fixedly provided with pipe sleeves 302. The two sides of the pipe sleeves 302 are surrounded by flanges 305 that are respectively pressed by the first pipe opening 300 and the second pipe opening 301. The pipe sleeves 302 are connected by a flexible pipe 303.

[0025] A locking device 4 is disposed on one side of the pivot mechanism 3 and is used to lock the first pipe fitting 1 and the second pipe fitting 2 in a horizontal state.

[0026] In the above structure, the first pipe fitting and the second pipe fitting are respectively connected to the first pivot joint and the second pivot joint. The first pivot joint and the second pivot joint are rotatably connected together by a pivot. The two ends of the flexible pipe are fitted into the pipe sleeves on both sides. The flanges surrounding the outer periphery of the pipe sleeves are pressed inward by the inner walls of the first and second pipe openings, so that the two pipe sleeves are fixedly connected to the two ends of the flexible pipe respectively. When the user needs to store the folded pipe, he moves the first pivot joint or the second pivot joint to rotate around the pivot. The first pivot joint drives the first pipe fitting or the second pivot joint to move the second pipe fitting, so that the first pipe fitting and the second pipe fitting form a parallel shape, thereby reducing the overall length of the folded pipe for easy storage.

[0027] When the user needs to use the folding tube, the first or second pivot joint is moved to rotate in the opposite direction around the pivot. The first pivot joint drives the first tube or the second pivot joint to move the second tube, so that the first and second tubes are in a horizontal state on the same plane. Then, the pivot joint mechanism is locked by the locking device, so that the first and second tubes are locked in a horizontal state. Thus, the folding tube can be used like a rigid tube to facilitate the user's use.

[0028] Specifically, one end of the first tube 1 is fixedly provided with a fixing part 12 for disassembling or installing the vacuum head. The fixing part 12 is provided with a button 13 for locking or unlocking the vacuum head. Vacuum heads with different functions can be disassembled or installed multiple times through the fixing part, so that the vacuum cleaner can work in different scenarios and reduce the difficulty of replacing the vacuum head.

[0029] Specifically, the locking device 4 includes a locking arm 41 rotatably mounted on the first pivot portion 30 via a rotating shaft 40 and a locking protrusion 42 mounted on the second pivot portion 31. The end of the locking arm 41 is provided with a protrusion 43 that cooperates with the locking protrusion 42. The rotating shaft is located in the middle of the locking arm to form a rocker structure. By pressing or releasing one side of the locking arm, the locking arm on the other side is raised or lowered, thereby driving the protrusion to move upward to control the locking state between the protrusion and the locking protrusion.

[0030] Specifically, a sealing ring 304 is provided between the first pipe opening 300 and the second pipe opening 301 and the pipe sleeve 302. The sealing ring can increase the sealing performance of the first and second pipe openings and the pipe sleeve.

[0031] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
