Specific embodiments

[0021] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of non-conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0022] Referring to Figures 1-6 , a storage rack includes a base 1 and a support rod 2. The support rod 2 is installed on the base 1 and is perpendicular to the base 1. The support rod 2 includes a bottom rod 21, a top rod 22, and an extension assembly 3. The bottom rod 21, the top rod 22, and the extension assembly 3 are connected to each other. The distance between the top rod 22 and the base 1 is adjusted through the extension assembly 3. During use, the distance between the bottom rod 21 and the top rod 22 can be extended through the extension assembly 3, thereby extending the height of the entire storage rack. Even if there are more replacement heads of the vacuum cleaner for replacement, sufficient storage space can be obtained by extending the height of the storage rack. Therefore, it is not necessary to replace frequently, and it is more convenient to use.

[0023] Referring to Figures 1-2 , the extension assembly 3 includes several extension rods 31. The several extension rods 31 are connected in sequence to form a long rod. One end of the long rod is connected to the top rod 22, and the other end of the long rod is connected to the bottom rod 21. When extension is needed, the multiple extension rods 31 can be first assembled. Specifically, the extension rods 31 can be assembled by threaded connection. That is, threads are provided at the ends of each extension rod 31, and the threads at the two ends of the same extension rod 31 are set differently. One end is set as external threads, and the other end is set as internal threads. Correspondingly, mutually matching external threads and internal threads are also set on the bottom rod 21 and the top rod 22. That is, if internal threads are set on the bottom rod 21, corresponding external threads are set on the top rod 22. When no extension rod 31 is needed, the bottom rod 21 and the top rod 22 can also be threadedly connected to form a whole. When extension rods 31 are needed, one extension rod 31 can be threadedly connected to the bottom rod 21 and the top rod 22 according to the required length. Of course, multiple extension rods 31 can also be threadedly connected to each other first and then uniformly threadedly connected to the bottom rod 21 and the top rod 22 to extend the height of the entire storage rack. The extended height can also be used to store replacement parts of the vacuum cleaner, thereby improving the storage capacity of the same storage rack and making it more convenient to use.

[0024] Referring to Figures 3-6, Another implementation of the extension component 3 includes a limiting portion 33 and an extension portion. The extension portion is provided at the bottom of the ejector rod 22. The bottom rod 21 is provided with a receiving hole along the axial direction of the bottom rod 21. The extension portion is inserted into the receiving hole and slides within the receiving hole. The limiting portion 33 is provided on the bottom rod 21 for locking the bottom rod 21 and the extension portion.

[0025] In this implementation, the extension portion includes an extension rod 32. The extension rod 32 and the ejector rod 22 can be integrally formed, or can be connected by welding, or a section of the original ejector rod 22 can be used as the extension rod 32. The extension rod 32 is fixed at the bottom of the ejector rod 22 and is coaxially fixed with the ejector rod 22. The extension rod 32 is inserted into the receiving hole and reciprocates within the receiving hole along the length direction of the receiving hole. In this way, the ejector rod 22 can be driven to move up and down, and then the height of the storage rack can be adjusted according to actual needs. The extension rod 32 can be locked and limited by the limiting portion 33, and then the storage space of the storage rack can be flexibly adjusted according to actual needs to complete the storage of different replacement parts of the vacuum cleaner.

[0026] Refer to Figures 3-4 , The following gives one of the solutions for the limiting portion 33. In this solution, the limiting portion 33 includes a limiting sleeve 331 and a limiting nut 332. The limiting sleeve 331 is fixed at the end of the bottom rod 21 and is coaxial with the receiving hole. The extension rod 32 passes through the limiting sleeve 331 and is inserted into the receiving hole. The inner wall of the limiting sleeve 331 fits against the outer wall of the extension rod 32. The limiting nut 332 is sleeved on the outer wall of the limiting sleeve 331 and is threadedly connected to the outer wall of the limiting sleeve 331. When the limiting nut 332 is threadedly connected to the limiting sleeve 331, the limiting nut 332 drives the limiting sleeve 331 to press against the outer wall of the extension rod 32. The limiting sleeve 331 includes an annular main body. A plurality of relief slots 333 are provided on the main body. The plurality of relief slots 333 are arranged along the circumferential direction of the main body and extend along the length direction of the main body. The relief slots 333 divide the side wall of the main body into a plurality of locking petals. External threads for engaging with the limiting nut 332 are provided on the outer wall of the locking petals. That is, when adjustment is needed, only the limiting nut 332 needs to be loosened so that the locking petals change from a state of abutment to a relaxed state, and the abutment of the locking petals against the extension rod 32 can be released. Then the extension rod 32 can slide freely, adjust the height of the storage rack, and flexibly adjust the storage space of the storage rack according to actual needs to complete the storage of different replacement parts of the vacuum cleaner.

[0027] Refer to Figures 5-6, in the previous solution of the limiting part 33, the actually locked state is achieved by the friction between the locking flap and the extension rod 32. Once there are too many stored parts and the load on the storage rack is large, the locking effect of the locking flap alone is very limited, and the extension rod 32 is prone to abnormal sliding. Therefore, it is necessary to improve the limiting part 33. The improved limiting part 33 includes a V-shaped spring 334 and a limiting column 335. The interior of the extension rod 32 is hollow to form an installation cavity. The V-shaped spring 334 is arranged in the installation cavity. An extension hole is formed in the side wall of the extension rod 32. The extension hole communicates with the installation cavity. The limiting column 335 passes through the extension hole and inserts into the installation cavity and abuts against the V-shaped spring 334. A plurality of adjustment holes 336 are formed in the bottom rod 21 along the length direction of the bottom rod 21. When the extension rod 32 moves, the limiting column 335 sequentially passes through the adjustment holes 336. When the extension hole and the adjustment hole 336 are coaxial, the V-shaped spring 334 pushes the limiting column 335 to insert into the adjustment hole 336. When adjustment is needed, one hand needs to hold the limiting column 335, and the other hand needs to push the top rod 22 until the limiting column 335 moves into the next adjustment hole 336, then the top rod 22 can be locked. Repeating the above operation can flexibly adjust the height of the storage rack to obtain more storage space. Although each adjustment can only increase or decrease by a fixed height, compared with the solution using the locking flap, this solution limits the position by inserting the limiting column 335 into the adjustment hole 336 and the extension hole at the same time, and its weighing capacity increases.

[0028] Compared with the prior art, when the present utility model is in use, the distance between the bottom rod 21 and the top rod 22 can be extended by the extension assembly 3, and thus the height of the entire storage rack can be extended. Even if there are more replacement heads of the vacuum cleaner, enough storage space can be obtained by extending the height of the storage rack. Therefore, it is not necessary to replace frequently, and the use is more convenient.

[0029] The above embodiments are only the preferred embodiments of the present utility model, and the scope of protection of the present utility model cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present utility model fall within the scope of protection required by the present utility model.
