Description

Technical Field

[0001] This utility model relates to the technical field of vacuum cleaner pipe structure, specifically a vacuum cleaner pipe connection structure that is easy to install. Background Technology

[0002] Vacuum cleaners are one of the most common household appliances today. They use the high-speed rotation of a motor to suck up dust from the air, and then the dust is transported through a hose into a dust bag for centralized storage and processing. The efficient cleaning of vacuum cleaners greatly improves cleaning efficiency in various scenarios.

[0003] To improve ease of operation, current upright household vacuum cleaners typically have long and fixed pipe lengths. During transportation, uneven stress on both sides can easily lead to pipe bending and other problems. Furthermore, the pipe length of current upright household vacuum cleaners is usually not adjustable, requiring a large storage space, which is inconvenient for families with limited space.

[0004] To address the aforementioned issues, we have made improvements by proposing an easy-to-install vacuum cleaner pipe connection structure. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model provides a vacuum cleaner pipe connection structure that is easy to install, including an upper connecting pipe and a lower connecting pipe. The ends of the upper connecting pipe and the lower connecting pipe are respectively connected to a docking cavity. An extension pipe is slidably connected between the two docking cavities. Arc-shaped inner pressure plates are respectively connected to both sides of the extension pipe. An outer pressure plate and several spring assemblies are installed outside the inner pressure plate. Several connecting rods and docking parts are connected between the outer pressure plate and the inner pressure plate.

[0007] As a preferred technical solution of this utility model, the ends of the docking cavities of the upper connecting pipe and the lower connecting pipe can be spliced ​​together, a slider is installed on the outer surface of the extension pipe, and a sliding groove is opened on the inner surface of the two docking cavities. The slider is slidably connected to the sliding groove, and the extension pipe is located inside the docking cavity when the two docking cavities are spliced ​​together.

[0008] As a preferred embodiment of this utility model, several spring assemblies are respectively fixedly connected to the outer side of the inner pressure plate, and the other end of each spring assembly is fixedly connected to the inner surface of the outer pressure plate. The bottom of the connecting rod is fixedly connected to the outside of the inner pressure plate.

[0009] As a preferred technical solution of this utility model, the top of the docking component is fixedly connected to the inner surface of the outer pressure plate, the end of the connecting rod is provided with a reserved groove, the surface of the docking component is provided with an installation groove, the two sides of the installation groove are respectively fixedly connected with limit strips, and the docking component is slidably connected to the connecting rod through the limit strips and the reserved groove.

[0010] As a preferred embodiment of this utility model, one of the outer pressure plates has a card hinged to its outer surface, and the other outer pressure plate has a slot on its surface. The end of the card is fixedly connected to a plug that engages with the slot, and the length of the inner pressure plate is less than that of the outer pressure plate.

[0011] As a preferred technical solution of this utility model, after the two docking cavities are moved to both sides of the extension tube, the exposed length of the extension tube is consistent with the width of the inner pressure plate, and the inner surface of the inner pressure plate is installed in close contact with the outer surface of the extension tube.

[0012] The beneficial effects of this utility model are as follows: This easy-to-install vacuum cleaner pipe connection structure allows the extension tube to be stored through two docking cavities during transportation and storage. At this time, the docking surfaces of the two docking cavities are in contact, reducing the overall height of the upright vacuum cleaner and lowering the packaging and space requirements for transportation and storage. At the same time, during use, the inner pressure plate uses the inner pressure plate to hold the exposed extension tube from both sides, preventing the extension tube from shrinking back under force during use, thus maintaining a comfortable operating height for the vacuum cleaner. Furthermore, the inner spring of the outer pressure plate presses against the extension tube, making the connection between the inner pressure plate and the extension tube more secure. This also allows the limiting structure composed of the inner and outer pressure plates to adapt to the installation of different pipes. During transportation, installing the limiting structure composed of the inner and outer pressure plates on the upper and lower connecting pipes reduces transportation and packaging processes and lowers the difficulty of storage.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figure 1-5 As shown, a vacuum cleaner pipe connection structure that is easy to install includes an upper connecting pipe 1 and a lower connecting pipe 2. The ends of the upper connecting pipe 1 and the lower connecting pipe 2 are respectively connected to docking chambers 3. An extension pipe 16 is slidably connected between the two docking chambers 3. Arc-shaped inner pressure plates 6 are respectively connected to both sides of the extension pipe 16. An outer pressure plate 4 and several spring assemblies 7 are installed on the outside of the inner pressure plate 6. Several connecting rods 8 and docking parts 12 are connected between the outer pressure plate 4 and the inner pressure plate 6.

[0022] The ends of the connecting chambers 3 of the upper connecting tube 1 and the lower connecting tube 2 can be joined together. During transportation and storage, the two connecting chambers 3 can be joined together to store the extension tube 16 inside the connecting chamber 3. This storage method can effectively reduce the overall length of the vacuum cleaner, reduce the storage space required, and reduce problems such as damage to the pipes due to the large length during transportation. After the vacuum cleaner is taken out, the two connecting chambers 3 will naturally detach under the action of gravity. A slider 11 is installed on the outer surface of the extension tube 16, and a groove 17 is opened on the inner surface of the two connecting chambers 3. The slider 11 is slidably connected to the groove 17. When the slider 11 slides to the end of the groove 17, the middle part of the extension tube 16 is exposed, so that the height of the vacuum cleaner is restored to the optimal usage height and the comfort of operation is maintained.

[0023] Several spring assemblies 7 are fixedly connected to the outer side of the inner pressure plate 6, and the other end of each spring assembly 7 is fixedly connected to the inner surface of the outer pressure plate 4. The bottom of the connecting rod 8 is fixedly connected to the outside of the inner pressure plate 6.

[0024] The top of the docking part 12 is fixedly connected to the inner surface of the outer pressure plate 4. A reserved groove 14 is provided at the end of the connecting rod 8. An installation groove 15 is provided on the surface of the docking part 12. Limiting strips 13 are fixedly connected to both sides of the installation groove 15. The docking part 12 is slidably connected to the connecting rod 8 through the limiting strips 13 and the reserved groove 14.

[0025] The inner pressure plate 6 is attached to the exposed part of the extension tube 16 from both sides, and the outer pressure plate 4 is pressed inward according to the size of the extension tube 16. At this time, the spring assembly 7 is compressed by force. The end plug 10 of the card 5 is inserted into the slot 9 of the other outer pressure plate 4. The friction between the slot 9 and the plug 10 can make both inner pressure plates 6 stably attach to the outside of the extension tube 16. When removing, the plug 10 can be dislodged by forcefully prying the card 5 outward.

[0026] One of the outer pressure plates 4 has a card 5 hinged to its outer surface, and the other outer pressure plate 4 has a slot 9 on its surface. The end of the card 5 is fixedly connected to a plug 10 that engages with the slot 9. The inner pressure plate 6 is shorter than the outer pressure plate 4, so that the inner pressure plate 6 can be adapted to the installation of extension tubes 16 of different diameters. Moreover, the inner pressure plate 6 can be directly installed on the upper connecting tube 1 and the lower connecting tube 2 during transportation or storage, reducing the difficulty of individual storage.

[0027] After moving the two docking cavities 3 to both sides of the extension tube 16, the exposed length of the extension tube 16 is consistent with the width of the inner pressure plate 6. After the inner pressure plate 6 is installed, the two docking cavities 3 can be prevented from moving towards each other. The inner surface of the inner pressure plate 6 is installed in close contact with the outer surface of the extension tube 16.

[0028] Working Principle: This easy-to-install vacuum cleaner pipe connection structure allows the ends of the connecting chambers 3 of the upper connecting pipe 1 and the lower connecting pipe 2 to be joined together during use. During transportation and storage, the extension pipe 16 can be stored inside the connecting chambers 3 by joining the ends of the two connecting chambers 3. This storage method effectively reduces the overall length of the vacuum cleaner, reduces storage space requirements, and also reduces the risk of pipe damage due to compression during transportation. Furthermore, after removing the vacuum cleaner, the two connecting chambers 3 naturally detach under gravity. A slider 11 is installed on the outer surface of the extension pipe 16, and grooves 17 are formed on the inner surfaces of both connecting chambers 3. 11 is slidably connected to the slide groove 17. The slider 11 slides to the end of the slide groove 17. At this time, the middle part of the extension tube 16 is exposed, so that the height of the vacuum cleaner is restored to the optimal use height and the comfort of operation is maintained. The inner pressure plate 6 is attached to the exposed part of the extension tube 16 from both sides and the outer pressure plate 4 is pressed inward according to the size of the extension tube 16. At this time, the spring assembly 7 is compressed by force. The end plug 10 of the card 5 is inserted into the slot 9 of the other outer pressure plate 4. The friction between the slot 9 and the plug 10 can make both inner pressure plates 6 stably attach to the outside of the extension tube 16. When removing, the plug 10 can be dislodged by forcefully prying the card 5 outward.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
