Description

Technical Field

[0001] This utility model relates to the technical field of duster handles, and in particular to a duster handle. Background Technology

[0002] A duster is a tool used to clean dust and debris from surfaces. It typically consists of a long handle and a head with a brush, feathers, cloth, or similar material attached to one end. It is primarily used to clean hard-to-reach areas such as tops of bookshelves, furniture, curtain rods, and ceiling corners.

[0003] However, the fixed length of existing dusters does not meet the cleaning needs of different heights. The fixed length of dusters may not be suitable for different cleaning environments, especially for high places that are difficult to reach. If the duster is not long enough, it cannot clean the dust accumulated on the ceiling, the top of the bookshelf, etc. If it is too long, it may be inconvenient to operate in a small space. Different cleaning tasks require dusters of different lengths, which limits the scope of application and has defects. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of existing dusters with fixed lengths, which are not suitable for cleaning needs at different heights. The fixed length of the duster may not be suitable for different cleaning environments, especially for high and hard-to-reach places. If the duster is not long enough, it cannot clean the dust accumulated on high places such as the ceiling and the top of the bookshelf. If it is too long, it may be inconvenient to operate in a small space. Different cleaning tasks require dusters of different lengths, which limits the scope of application and has technical defects. Therefore, this invention proposes a duster handle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a duster handle, comprising a connecting rod, a duster head fixedly connected to one end of the connecting rod, a handle body sleeved on the other end of the connecting rod, a lead screw rotatably connected to the inner wall surface of the handle body via a bearing, the outer surface of the lead screw threadedly connected to the inside of the connecting rod, a guide block fixedly connected to the other end of the lead screw, a support ring fixedly connected to one end of the guide block, a spring fixedly connected to one side surface of the support ring, an adjusting ring fixedly connected to one end of the spring, an adjusting ring sleeved on the inner wall surface of the adjusting ring on the outer surface of the guide block, a locking block fixedly connected to one side surface of the adjusting ring, and multiple grooves formed on one side surface of the handle body, the outer surface of the locking block being embedded in one of the grooves.

[0006] Furthermore, a linear bearing is fixedly connected to the inner wall surface of the handle body, and the inner wall surface of the linear bearing is sleeved on the outer surface of the connecting rod.

[0007] Furthermore, three support blocks are fixedly connected to the connecting rod near the outer surface of the support ring, and the three support blocks are equidistantly distributed.

[0008] Furthermore, the outer surface of the adjusting ring is provided with multiple anti-slip grooves, which are equidistantly distributed.

[0009] Furthermore, the inner wall surface of the spring is fitted onto the outer surface of the guide block.

[0010] Furthermore, a silicone sleeve is fitted onto the outer surface of the handle body.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, when dusting high places, the adjusting ring is pulled towards the end away from the connecting rod. The adjusting ring compresses the spring, causing the guide block to rotate through the bearing and the screw. Under the action of the thread, the connecting rod is pushed away from the handle body, extending the distance between the duster head and the handle body. After adjustment, the adjusting ring is released, and the adjusting ring slides along the outer surface of the guide block under the push of the spring, causing the locking block to be embedded in the corresponding groove. When the duster head is cleaning dust, the locking block and the groove cooperate, and the adjusting ring restricts the guide block, preventing the duster head from rotating through the connecting rod after being subjected to force. The height of the duster head during use can be freely adjusted as needed, making it suitable for different needs and with a wide range of applications.

[0013] In this invention, the linear bearing prevents the connecting rod from rotating relative to the handle body and reduces the friction between the connecting rod and the handle body. Three equidistantly distributed support blocks prevent the connecting rod from wobbling inside the handle body, ensuring the stability of the components. Multiple equidistantly distributed anti-slip grooves evenly increase the friction between the palm and the adjusting ring, preventing slippage. When the spring is subjected to lateral force, the guide block provides support to prevent the spring from bending and ensure the normal operation of the components. The silicone sleeve deforms when the handle body is gripped, conforming to the palm and improving comfort. Attached Figure Description

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a duster handle, including a connecting rod 1, a duster head 2 fixedly connected to one end of the connecting rod 1, a handle body 7 sleeved on the other end of the connecting rod 1, a lead screw 9 rotatably connected to the inner wall surface of the handle body 7 via a bearing, the outer surface of the lead screw 9 threadedly connected to the inside of the connecting rod 1, a guide block 8 fixedly connected to the other end of the lead screw 9, a support ring 6 fixedly connected to one end of the guide block 8, a spring 5 fixedly connected to one side surface of the support ring 6, an adjusting ring 4 fixedly connected to one end of the spring 5, the inner wall surface of the adjusting ring 4 sleeved on the outer surface of the guide block 8, a locking block 11 fixedly connected to one side surface of the adjusting ring 4, and a plurality of grooves 10 formed on one side surface of the handle body 7, the outer surface of the locking block 11 being embedded in the interior of one of the grooves 10.

[0021] In this embodiment, when dusting high places, the adjusting ring 4 is pulled away from the end of the connecting rod 1. The adjusting ring 4 compresses the spring 5, causing the guide block 8 to be stressed and drive the lead screw 9 to rotate through the bearing. Under the action of the thread, the connecting rod 1 is pushed away from the handle body 7, extending the distance between the duster head 2 and the handle body 7. After adjustment, the adjusting ring 4 is released. The adjusting ring 4 slides along the outer surface of the guide block 8 under the push of the spring 5, so that the locking block 11 is embedded in the corresponding groove 10. When the duster head 2 cleans dust, the locking block 11 and the groove 10 cooperate, and the adjusting ring 4 restricts the guide block 8, preventing the duster head 2 from being stressed and driving the lead screw 9 to rotate through the connecting rod 1. The height of the duster head 2 during use can be freely adjusted as needed, which can be adapted to different needs and has a wide range of applications. Example

[0022] like Figure 1-4As shown, a linear bearing 12 is fixedly connected to the inner wall surface of the handle body 7. The inner wall surface of the linear bearing 12 is sleeved on the outer surface of the connecting rod 1. Three support blocks 13 are fixedly connected to the outer surface of the connecting rod 1 near the support ring 6. The three support blocks 13 are equidistantly distributed.

The inner wall surface of the spring 5 is sleeved on the outer surface of the guide block 8. A silicone sleeve 3 is sleeved on the outer surface of the handle body 7.

[0023] In this embodiment, the linear bearing 12 prevents the connecting rod 1 from rotating relative to the handle body 7 and reduces the friction between the connecting rod 1 and the handle body 7. Three equidistant support blocks 13 prevent the connecting rod 1 from shaking inside the handle body 7, ensuring the stability of the components. Multiple equidistant anti-slip grooves 14 evenly increase the friction between the palm and the adjusting ring 4, preventing hand slippage. When the spring 5 is subjected to lateral force, the guide block 8 provides support to prevent the spring 5 from bending and ensure the normal operation of the components. The silicone sleeve 3 deforms when the handle body 7 is held, conforming to the palm and improving comfort.

[0024] Working principle: such as Figure 1-4 As shown, when dusting high places, pull the adjusting ring 4 away from the end of the connecting rod 1. The adjusting ring 4 compresses the spring 5, causing the guide block 8 to be stressed and rotate through the bearing to drive the screw 9 to rotate. Under the action of the thread, the connecting rod 1 is pushed away from the handle body 7, extending the distance between the duster head 2 and the handle body 7. After adjustment, release the adjusting ring 4. The adjusting ring 4 slides along the outer surface of the guide block 8 under the push of the spring 5, causing the locking block 11 to be embedded in the corresponding groove 10. When the duster head 2 sweeps dust, the locking block 11 and the groove 10 cooperate, and the adjusting ring 4 restricts the guide block 8, preventing the duster head 2 from being stressed and passing through the connecting rod. 1. The screw 9 rotates, allowing the height of the duster head 2 to be freely adjusted as needed, adapting to different requirements. 2. The linear bearing 12 prevents the connecting rod 1 from rotating relative to the handle body 7 and reduces friction between the connecting rod 1 and the handle body 7. 3. Three equidistant support blocks 13 prevent the connecting rod 1 from wobbling inside the handle body 7, ensuring the stability of the components. 4. Multiple equidistant anti-slip grooves 14 evenly increase the friction between the palm and the adjusting ring 4. 5. When the spring 5 is subjected to lateral force, the guide block 8 provides support to prevent the spring 5 from bending. 6. The silicone sleeve 3 deforms when the handle body 7 is held.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
