[0002] A vacuum cleaner is a commonly used household cleaning tool. Its working principle is that the vacuum cleaner motor rotates at a high speed, creating a certain vacuum in the dust box. Dust enters the filter dust bag in the dust box through the floor brush, telescopic pipe, handle, hose, and main suction pipe, so as to recycle the dust uniformly;

[0003] At present, the inner pipe and the outer pipe of some vacuum cleaner telescopic pipes are integrally connected. When one of the components is damaged, it often leads to the need to replace the entire telescopic pipe part, greatly increasing the maintenance cost. Although the inner pipe and the outer pipe of another part of the vacuum cleaner telescopic pipe are detachable and assembled, their disassembly and assembly are relatively cumbersome, reducing the working efficiency during daily cleaning use. Therefore, to solve this problem, designing an assembly structure of the inner pipe and the outer pipe of a vacuum cleaner telescopic pipe is what we need to consider. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an assembly structure of an inner pipe and an outer pipe of a vacuum cleaner telescopic pipe. In view of the assembly problem, by buckling two hook-shaped connection blocks on the corresponding first connection blocks and cooperating with the limit block and two springs, simple and quick assembly and control of the telescopic length can be realized, effectively improving the working efficiency during cleaning, and the overall adopts a split design, effectively reducing the maintenance cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Referring to Figures 1-4 , an assembly structure of an inner tube and an outer tube of a vacuum cleaner telescopic tube, including an inner tube body 1, a plurality of annular limiting grooves 2 are opened on the outer side of the inner tube body 1, and an outer tube body 3 is arranged at the rear side of the inner tube body 1. First connecting blocks 4 are fixedly connected to the left and right sides of the outer tube body 3, and limiting through grooves 5 are horizontally opened on the front sides of the two first connecting blocks 4;

[0021] Among them, an assembly mechanism is further included. The assembly mechanism is used to assemble and connect the inner tube body 1 and the outer tube body 3. The assembly mechanism includes an assembly tube 6 arranged between the inner tube body 1 and the outer tube body 3. A first circular through groove 7 is opened on the front side of the assembly tube 6, and a second circular through groove 8 is opened on the rear side of the assembly tube 6. The inner wall radius of the first circular through groove 7 is equal to the outer circle radius of the inner tube body 1, and the inner wall radius of the second circular through groove 8 is equal to the outer circle radius of the outer tube body 3. The rear side of the first circular through groove 7 communicates with the front side of the second circular through groove 8, and a rectangular inner groove 9 is opened at the inner top of the first circular through groove 7;

[0022] Among them, a limiting block 10 that can move up and down is slidably connected in the rectangular inner groove 9. The lower end surface of the limiting block 10 is an arc surface and can be attached to the inner wall of the inner circle of the annular limiting groove 2. The limiting block 10 cooperates with a plurality of annular limiting grooves 2. By inserting the limiting block 10 into the corresponding annular limiting groove 2, the inner tube body 1 and the assembly tube 6 can be assembled, and at the same time, the telescopic length of the inner tube body 1 can be controlled. The upper end of the limiting block 10 is elastically connected to the inner top of the rectangular inner groove 9 through two springs 11. The upper end of the limiting block 10 is fixedly connected to a second connecting block 12. The upper end of the second connecting block 12 penetrates through the inner top of the rectangular inner groove 9 and extends to the outside. A sealing ring 13 is fixedly connected to the front side inner wall of the second circular through groove 8. The sealing ring 13 can improve the sealing performance of the whole device. Two hook-shaped connecting blocks 14 are fixedly connected to the rear side of the assembly tube 6. The hook-shaped connecting block 14 is composed of a plate-shaped part at the front side and a hook-shaped part at the rear side. The plate-shaped part of the hook-shaped connecting block 14 is made of an elastic material that can be deformed by force. The two hook-shaped connecting blocks 14 respectively cooperate with the corresponding limiting through grooves 5. By inserting the two hook-shaped connecting blocks 14 into the corresponding limiting through grooves 5 respectively, the outer tube body 3 and the assembly tube 6 can be assembled.

[0023] In the present utility model, during use, first assemble the outer tube body 3 and the assembly tube 6. Align the front end of the outer tube body 3 with the second circular through groove 8 and insert it. At the same time, ensure that the two hook-shaped connection blocks 14 are respectively aligned with the corresponding limit through grooves 5. During the insertion process, the hook-shaped parts of the two hook-shaped connection blocks 14 will respectively contact the corresponding first connection blocks 4. At this time, the plate-shaped parts of the two hook-shaped connection blocks 14 will deform. Then continue to insert so that the two hook-shaped connection blocks 14 respectively penetrate the corresponding limit through grooves 5, so that the two hook-shaped connection blocks 14 respectively latch onto the corresponding first connection blocks 4. In this way, the assembly of the outer tube body 3 and the assembly tube 6 is completed. When subsequent disassembly is required, just push the two hook-shaped connection blocks 14 out of the corresponding limit through grooves 5;

[0024] After completing the assembly of the outer tube body 3 and the assembly tube 6, start assembling the inner tube body 1 and the assembly tube 6. Align the rear end of the inner tube body 1 with the first circular through groove 7 and insert it. During the insertion process, pull up the second connection block 12 to drive the limit block 10 to move up into the rectangular inner groove 9, and make the two springs 11 be compressed under force. At this time, the insertion depth of the inner tube body 1 can be controlled according to the actual situation. After determining the insertion depth, move the corresponding annular limit groove 2 to the position of the limit block 10, and release the second connection block 12. Due to the elastic action of the two springs 11, the limit block 10 moves down and inserts into the corresponding annular limit groove 2. In this way, the assembly of the inner tube body 1 and the assembly tube 6 is completed. When subsequent adjustment of the telescopic length of the inner tube body 1 or removal of the inner tube body 1 from the assembly tube 6 is required, just pull up the second connection block 12 to ensure the free movement of the inner tube body 1. The whole device adopts a split design, and each component is independently arranged. If one of the components is damaged, just replace the corresponding component, effectively reducing the maintenance cost. At the same time, the overall assembly and disassembly are simple and fast, effectively improving the working efficiency during daily cleaning use.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
