Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present application provides a bendable telescopic tube. The bendable telescopic tube in the embodiments of the present application can be used in a vacuum cleaner to clean hard-to-reach corners and crevices, and can also be used in an industrial environment, for example, for cleaning machinery, equipment, and production lines to meet different cleaning requirements. It can also be used for car cleaning: for example, it can be used to clean the interior of a car and hard-to-reach external areas to improve cleaning efficiency. Specifically, as Figure 1 and Figure 2 shown, the bendable telescopic tube includes a first base tube 1 and a second base tube 2. At least one of the first base tube 1 and the second base tube 2 is internally provided with a telescopic rod 8. One end of the first base tube 1 is used to connect with a first extension tube, the other end of the first base tube 1 is rotatably connected to the second base tube 2, and the other end of the second base tube 2 is used to connect with a second extension tube. In a first state, the first base tube 1 and the second base tube 2 form a first angle, and in a second state, the first base tube 1 and the second base tube 2 form a second angle. When changing from the first state to the second state, the first base tube 1 and the second base tube 2 rotate towards each other in the same direction and approach each other. When changing from the second state to the first state, the first base tube 1 and the second base tube 2 rotate away from each other in opposite directions.

[0028] Among them, the first state can be the initial state of the bendable telescopic tube. For example, it can be Figure 1In the straight state shown in the figure, at this time, the first base tube 1 and the second base tube 2 are kept in the same straight line, and the first angle between the first base tube 1 and the second base tube 2 can be 180°. Further, the second state can be a state where the first base tube 1 and the second base tube 2 are almost parallel to each other. At this time, the second angle between the first base tube 1 and the second base tube 2 is close to 0°. In this second state, the first base tube 1 and the second base tube 2 are equivalent to being folded, which is convenient for carrying. It can be understood that the above first state and second state are only exemplary descriptions. In other implementable solutions, the initial state of the bendable telescopic tube can also be a state with a certain bending angle that is not reset after being used last time, or the first base tube 1 and the second base tube 2 can also be in a state of being almost parallel to each other (the second state). It can be understood that when the first state is determined, the second state can be the state transformed from the first state.

[0029] It can be understood that in the embodiment of this application, through the rotational connection between the first base tube 1 and the second base tube 2, the pipeline can be freely converted between different angles, which improves the flexibility of the pipeline, reduces the manual labor intensity, and improves the cleaning efficiency. Moreover, the pipeline can be transformed between the first state and the second state, so that it can adapt to different cleaning scenarios and space layouts, improving the adaptability of the pipeline to different scenarios. And, by converting between the first state and the second state, the pipeline can occupy less space when not in use, which is convenient for storage and carrying. Further, this application can not only achieve telescoping based on the retractable rod, but also externally connect extension pipelines at both ends of the two base tubes to achieve a dual telescoping function, and this application does not limit the length of the extension tube and can adapt to the requirements of different length scenarios.

[0030] In some embodiments, referring to Figure 1 and Figure 2 , the first base tube 1 is connected to the first extension tube through the first connector 3, and the second base tube 2 is connected to the second extension tube through the second connector 4. Among them, the first connector 3 includes a first slot and a first plug. One end of the first base tube 1 is inserted into the first slot, and the first plug is inserted into the pipeline of the first base tube 1, so as to realize the connection between the first base tube 1 and the first connector 3. Further, a plurality of support frames protrude outward along the circumference of the first plug. The plurality of support frames extend towards the direction of the first slot. It can be understood that by setting the support frames, the strength of the first plug can be improved, and the support frames can reduce the thickness of the first slot and improve the insertion stability of the first base tube 1 in the first slot. Further, the structure of the second connector 4 can be designed to be the same as the structure of the first connector 3.

[0031] Further, in one embodiment, the first base tube 1 can be a straight tube, the second base tube 2 can retract a telescopic rod 8, and in another embodiment, both the first base tube 1 and the second base tube 2 can retract a telescopic rod 8. The retracted telescopic rod and the externally connected extension tube together improve the adaptability of the bendable telescopic tube to different scenarios.

[0032] In some embodiments, the first base tube 1 and the second base tube 2 are rotatably connected by a rotating shaft. It can be understood that the rotating shaft can be a simple pin shaft, as long as it can achieve the mutual rotation between the first base tube 1 and the second base tube 2. Through the design of the rotating shaft, the rotation operation of the pipeline is made more direct and convenient.

[0033] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 shown, the bendable telescopic tube includes a first connecting sleeve 5 and a second connecting sleeve 6. A first rotation assisting member 51 protrudes from the outer side wall of the first connecting sleeve 5, and a second rotation assisting member 61 protrudes from the outer side wall of the second connecting sleeve 6. A through hole is provided in either the first rotation assisting member 51 or the second rotation assisting member 61, and a rotating shaft is provided on the other one. The rotating shaft is sleeved in the through hole, and the axis of the rotating shaft is parallel to the radial direction of the first base tube 1 or the second base tube 2.

[0034] In some embodiments, the bendable telescopic tube further includes a flexible tube 7. One end of the flexible tube 7 extends into the first connecting sleeve 5, and the other end of the flexible tube 7 extends into the second connecting sleeve 6. When changing from the first state to the second state, a third angle is also formed between the first base tube 1 and the second base tube 2. The flexible tube 7 is used to support and define the positions of the first base tube 1 and the second base tube 2 at the third angle. Specifically, the flexible tube 7 has a certain plasticity and can provide support when the third angle is formed between the first base tube 1 and the second base tube 2, ensuring the stability of the pipeline structure at different angles. It should be noted that the third angle can be any angle other than the first angle and the second angle when the first base tube 1 and the second base tube 2 rotate relative to each other. When the first base tube 1 and the second base tube 2 are bent to the third angle, the flexible tube 7 realizes the supporting function, thereby realizing the stability of the bendable telescopic tube at the third angle for cleaning work.

[0035] In some embodiments, one end of the first connecting sleeve 5 is sleeved with the first base tube 1, the other end of the first connecting sleeve 5 is rotatably connected to the second connecting sleeve 6 through a through hole or a rotating shaft, and the other end of the second connecting sleeve 6 is sleeved with the second base tube 2. Specifically, the first connecting sleeve 5 is sleeved outside the first base tube 1, and the second connecting sleeve 6 is sleeved outside the second base tube 2.

[0036] In some embodiments, such as Figure 3 , Figures 5 to 9As shown in the figure, a through hole 52 is formed in the first rotation assisting member 51. The first rotation assisting member 51 includes two side plates 53 arranged oppositely, and an avoidance groove 56 located between the two side plates 53. The through hole 52 penetrates through both side plates 53. A rotating shaft 62 is provided on the second rotation assisting member 61. The second rotation assisting member 61 includes two wing plates 63 arranged oppositely. A rotating shaft 62 protrudes from each wing plate 63. The two rotating shafts 62 are correspondingly inserted into the two through holes 52. It can be understood that by providing the avoidance groove 56 on the first assisting member, when the first base pipe 1 and the second base pipe 2 rotate relative to each other, the second assisting member can be avoided, reducing the problem that the bending angle of the base pipe is insufficient due to the mutual abutment between the first assisting member and the second assisting member, and expanding the bending angle of the base pipe.

[0037] In some embodiments, the two rotating shafts 62 on the two wing plates 63 face away from each other, and the two wing plates 63 are located between the two side plates 53, or the two rotating shafts 62 on the two wing plates 63 are close to each other, and the two wing plates 63 are correspondingly arranged outside the two side plates 53.

[0038] In some embodiments, the rotating shaft 62 is configured as a hollow rotating shaft 62. The hollow of the rotating shaft 62 communicates with the corresponding wing plate 63. The first rotation assisting member 51 further includes a first baffle 54 and a second baffle 55. The first baffle 54 and the second baffle 55 are correspondingly arranged outside the two side plates 53. A locking member 541 is provided on the first baffle 54. After the locking member 541 penetrates through the hollow of the rotating shaft 62, it is blocked by the corresponding wing plate 63. The designs of the side plates 53 and the wing plates 63 disperse the stress during the rotation of the pipeline, reduce the wear, and thus improve the durability of the pipeline.

[0039] In some embodiments, the second rotation assisting member 61 further includes a connecting plate 64 and a cover plate 65. The two ends of the connecting plate 64 are respectively connected to the two wing plates 63. A clamping groove 641 is formed in the connecting plate 64. The cover plate 65 is covered above the second rotation assisting member 61. A clamping buckle 651 is provided on the cover plate 65. The clamping buckle 651 is clamped with the clamping groove 641. By providing the baffle and the cover plate 65, the aesthetics of the first assisting member and the second assisting member are improved.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
