Description

Technical Field

[0001] This utility model belongs to the field of cleaning tool technology, and in particular relates to an adjustable length cleaning tool. Background Technology

[0002] Traditional cleaning tools are mostly of fixed length, which can cause many inconveniences in actual cleaning scenarios. For example, when cleaning high windows, ceiling corners, or chandeliers, fixed-length tools cannot reach these locations if they are too short. On the other hand, when cleaning lower locations such as the bottom of furniture or low corners of walls, tools that are too long will be cumbersome and difficult to operate. Therefore, adjustable-length cleaning tools are needed to clean these locations.

[0003] However, existing adjustable-length cleaning tools can often only be adjusted in one direction during use. Users need to spend a lot of time adjusting the length of the cleaning tool, which prolongs the work period. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable length cleaning tool. By setting a two-way adjustment mechanism, it solves the problem that existing adjustable length cleaning tools can often only be adjusted in one direction during use, and users need to spend a lot of time adjusting the length of the cleaning tool, thus extending the work period.

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

[0006] This utility model is an adjustable length cleaning tool, including two support rods, and the two support rods are provided with a bidirectional adjustment mechanism and a locking mechanism;

[0007] Both of the two support rods have circular grooves on their adjacent sides. A support plate is provided below the lower support rod, and a cleaning cotton is provided at the bottom of the support plate. A connecting block is fixedly connected to the bottom of the lower support rod, and a connecting block is fixedly connected to the top of the support plate. The bottom of the connecting block is hinged to the connecting block. The bidirectional adjustment mechanism includes an adjustment component 1 and an adjustment component 2. The adjustment component 1 includes a connecting rod that is slidably connected to the inner wall of the two circular grooves, and a rectangular groove is provided inside the connecting rod.

[0008] Furthermore, a rotating shaft is rotatably connected to the inner wall of the rectangular groove, the rotating shaft rotatably passes through the connecting rod, and a gear is fixedly connected to the outer wall of the rotating shaft.

[0009] Furthermore, the second adjustment component includes two rectangular sliding grooves formed on the connecting rod, and racks are slidably connected to the left and right inner walls of the connecting rod, with both racks meshing with gears.

[0010] Furthermore, rectangular connecting blocks are fixedly connected to the two racks on their opposite sides. The two rectangular connecting blocks slide through the two rectangular grooves on their opposite sides and are fixedly connected to the two support rods respectively. A handle is fixedly connected to the front extension of the rotating shaft.

[0011] Furthermore, the locking mechanism includes a second support plate fixedly connected to the outer wall of the connecting rod, a limit rod slidingly passing through the central axis of the second support plate, and the bottom of the limit rod slidingly passing through the rotating shaft.

[0012] Furthermore, a circular limiting piece is fixedly connected to the outer wall of the limiting rod, the bottom of the circular limiting piece is in contact with the rotating shaft, a spring is sleeved on the outer wall of the limiting rod, the top of the spring is fixedly connected to the second support plate, and the bottom of the spring is fixedly connected to the circular limiting piece.

[0013] Furthermore, a second handle is fixedly connected to the top extension of the limiting rod, and two gaskets are fixedly connected to the bottom of the second handle.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a two-way adjustment mechanism, when the length of the cleaning tool needs to be adjusted, handle one can be turned. Handle one drives the gear on the rotating shaft to rotate. When the gear rotates, it will drive the two racks to move away from each other. When the two racks move away from each other, they will drive the two support rods to move away from each other through the two rectangular connecting blocks. This completes the adjustment of the length of the cleaning tool. It allows the tool to be finely adjusted so that it can just reach the part that needs to be cleaned. It will not damage the furniture or fail to clean effectively because the tool is too long or too short. It also avoids the need to frequently change tools or make tedious one-way adjustments due to unsuitable tool length, thus saving time and making the cleaning work more efficient.

[0016] 2. By setting a locking mechanism, before turning handle one, first pull handle two. Handle two moves the limit rod upward until the limit rod is completely disengaged from the pivot. At this time, under the action of support plate two and circular limit piece, the spring is also in a compressed state. After the tool length adjustment is completed, release handle two. At this time, the limit rod is reinserted into the pivot under the elastic force of the spring, completing the locking of the tool length. This effectively prevents the tool length from being accidentally changed due to touching handle one when the length adjustment is not needed. It ensures that the mop handle length remains unchanged during the cleaning process, making the cleaning work smoother.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is an adjustable length cleaning tool, including two support rods 1. The tool is characterized by: a bidirectional adjustment mechanism 2 and a locking mechanism 3 on each of the two support rods 1; circular grooves 101 on the sides of the two support rods 1 that are close to each other; a support plate 102 below the lower support rod 1; a cleaning cotton 103 at the bottom of the support plate 102; a connecting block 104 fixedly connected to the bottom of the lower support rod 1; and a connecting block 205 fixedly connected to the top of the support plate 102. The bottom of the connecting block 104 is hinged to the connecting block 205. The bidirectional adjustment mechanism 2 includes an adjustment component 21 and an adjustment component 22. The adjustment component 21 includes a connecting rod 211 slidably connected to the inner walls of the two circular grooves 101. A rectangular groove 212 is formed inside the connecting rod 211. A rotating shaft 213 is rotatably connected to the inner wall of the rectangular groove 212, and the rotating shaft 213 rotatably passes through the connecting rod 211. Gear 214 is fixedly connected to the outer wall of component 3. Adjustment component 22 includes two rectangular slide grooves 221 opened on the connecting rod 211. Racks 222 are slidably connected to the left and right inner walls of the connecting rod 211. Both racks 222 mesh with gear 214. Rectangular connecting blocks 223 are fixedly connected to the sides of the two racks 222 that are far apart from each other. The sides of the two rectangular connecting blocks 223 that are far apart from each other slide through the two rectangular slide grooves 221 and are fixedly connected to the two support rods 1 respectively. Handle 224 is fixedly connected to the front extension of the rotating shaft 213. By setting the bidirectional adjustment mechanism 2, the length of the tool can be finely adjusted so that it can just reach the part that needs to be cleaned, without damaging the furniture or failing to clean effectively due to the tool being too long or too short. It also avoids the need to frequently change tools or make tedious one-way adjustments due to the tool length being unsuitable, thereby saving time and making the cleaning work more efficient.

[0028] The locking mechanism 3 includes a second support plate 301 fixedly connected to the outer wall of the connecting rod 211. A limit rod 302 slides through the central axis of the second support plate 301, and the bottom of the limit rod 302 slides through the rotating shaft 213. A circular limit piece 303 is fixedly connected to the outer wall of the limit rod 302. The bottom of the circular limit piece 303 contacts the rotating shaft 213. A spring 304 is sleeved on the outer wall of the limit rod 302. The top of the spring 304 is fixedly connected to the second support plate 301, and the bottom of the spring 304 is fixedly connected to the circular limit piece 303. A second handle 305 is fixedly connected to the top extension of the limit rod 302. Two pads 306 are fixedly connected to the bottom of the second handle 305. By setting the locking mechanism 3, the tool length can be effectively prevented from being accidentally changed due to touching the first handle 224 when the length adjustment is not required. This ensures that the mop handle length remains unchanged during the cleaning process, making the cleaning work smoother.

[0029] One specific application of this embodiment is as follows: In use, firstly, turn handle 224 according to the required length. Handle 224 drives gear 214 on shaft 213 to rotate. As gear 214 rotates, it causes two racks 222 to move away from each other. When the two racks 222 move away from each other, they also cause two support rods 1 to move away from each other via two rectangular connecting blocks 223. This completes the adjustment of the cleaning tool's length, allowing for fine-tuning to ensure the tool can just reach the area requiring cleaning. This prevents damage to furniture or ineffective cleaning due to the tool being too long or too short. Furthermore, it avoids frequent tool replacements or tedious one-way adjustments due to unsuitable tool length, saving time and making cleaning easier for the cleaning staff. To make the operation more efficient, before turning handle 224, first pull handle 305. Handle 305 moves the limiting rod 302 upward until the limiting rod 302 is completely disengaged from the rotating shaft 213. At this time, under the action of support plate 201 and circular limiting piece 303, spring 304 is also in a compressed state. After the tool length adjustment is completed, release handle 305. At this time, the limiting rod 302 is reinserted into the rotating shaft 213 under the elastic force of spring 304, thus locking the tool length. This effectively prevents the tool length from being accidentally changed due to touching handle 224 when the length adjustment is not needed. It ensures that the mop handle length remains unchanged during the cleaning process, making the cleaning work smoother.
