Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a self-retracting duster handle. Background Technology

[0002] As a cleaning tool in our daily lives, the duster plays an important role. It usually consists of two parts: a handle and a duster head. The handle is usually made of materials such as plastic, metal, or wood, while the duster head is mostly made of soft fibrous materials such as cotton, wool, or synthetic fibers. This tool is usually used to remove dust from furniture, appliances, and other surfaces, helping us maintain a clean and tidy living and working environment.

[0003] The traditional design of dusters and handles usually results in a relatively long handle. In actual use, a long handle makes it cumbersome to carry and inconvenient to carry around. Secondly, due to its large size, the duster takes up a relatively large amount of storage space, which is especially inconvenient in environments with limited space. This traditional design may be limited in modern home and office cleaning work due to its inconvenience in carrying and storing. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing duster handle is too long and inconvenient to store. Therefore, we propose a self-retracting duster handle.

[0005] To achieve the above objectives, this application adopts the following technical solution: a self-retracting duster handle, comprising a frame, a duster body fixedly connected to one side of the frame, slots provided at the top and bottom of one side of the frame, a support rod slidably connected to the inner wall of the frame, a circular groove provided at the top of the support rod, a limiting rod slidably connected to the inner wall of the circular groove, a spring fixedly connected to one end of the limiting rod, the other end of the spring fixedly connected to one side of the inner wall of the circular groove, and a handle body slidably connected to the inner wall of the support rod.

[0006] Preferably, the limiting rod has a sliding groove inside, and a T-shaped rod is slidably connected to the inner wall of the sliding groove. One end of the T-shaped rod is fixedly connected to one side of the inner wall of the circular groove.

[0007] Preferably, one end of the limiting rod is fixedly connected to a pull rod, and a long groove is provided on one side of the frame, with the surface of the pull rod slidably connected to the inner wall of the long groove.

[0008] Preferably, one end of the limiting rod has a rounded corner.

[0009] Preferably, extension blocks are fixedly connected to both sides of the top of the support rod, and limit grooves are opened on both sides inside the frame, with the surface of the extension block slidingly connected to the inner wall of the limit groove.

[0010] Preferably, a long rod is fixedly connected to one side of the bottom of the support rod, and a magnetic sliding rod is slidably connected to the surface of the long rod. Several round holes are opened on the surface of the handle body, and magnetic blocks are fixedly connected to the inner wall of the round holes.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, the worker pushes the limiting rod out of the slot, allowing the support rod to slide up and down inside the frame. When the worker pushes the limiting rod to compress the spring, the spring is compressed by the limiting rod, thus storing force. After the worker slides the support rod to the designated position inside the frame, the limiting rod is released, releasing the force generated by the spring. This causes the spring to rebound and push the limiting rod into the inner wall of the slot, thereby fixing the position of the support rod. This allows the support rod and the handle body to be retracted into the frame, reducing the external length of the support rod and making it easier to store and place the device. The self-retracting duster handle design not only improves the convenience of use but also saves storage space. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a self-retracting duster handle, including a frame 1, a duster body 2 fixedly connected to one side of the frame 1, slots 3 being provided at the top and bottom of one side of the frame 1, a support rod 4 slidably connected to the inner wall of the frame 1, a circular groove 5 being provided at the top of the support rod 4, a limiting rod 6 slidably connected to the inner wall of the circular groove 5, a spring 7 being fixedly connected to one end of the limiting rod 6, and the other end of the spring 7 being fixedly connected to one side of the inner wall of the circular groove 5, and a handle body 8 slidably connected to the inner wall of the support rod 4. The limiting rod 6 is pushed out of the slot 3 by the operator, allowing the support rod 4 to retract within the frame 1. The internal sliding mechanism allows the spring 7 to move when the operator pushes the limiting rod 6. The spring 7 is compressed by the limiting rod 6, thus storing force. After the operator slides the support rod 4 to the designated position inside the frame 1, the limiting rod 6 is released, releasing the force generated by the spring 7. This causes the spring 7 to rebound and push the limiting rod 6 into the inner wall of the slot 3, thereby fixing the position of the support rod 4. This allows the support rod 4 and the handle body 8 to be retracted into the frame 1, reducing the external length of the support rod 4 and making it easier to store and place the device. The self-retracting duster handle design not only improves the convenience of use but also saves storage space.

[0021] Reference Figure 4 As shown in this embodiment: a groove 9 is provided inside the limiting rod 6, and a T-shaped rod 10 is slidably connected to the inner wall of the groove 9. One end of the T-shaped rod 10 is fixedly connected to one side of the inner wall of the circular groove 5. By placing the T-shaped rod 10 in the groove 9, the movement trajectory of the limiting rod 6 is restricted, and the elastic force range of the spring 7 is limited, preventing the spring 7 from popping the limiting rod 6 out of the circular groove 5, ensuring that the limiting rod 6 moves linearly along the T-shaped rod 10 and improving the accuracy of the limiting rod 6 when it is inserted into the slot 3.

[0022] Reference Figure 1 and Figure 4 As shown in this embodiment: one end of the limiting rod 6 is fixedly connected to a pull rod 11, and a long groove 12 is opened on one side of the frame 1. The surface of the pull rod 11 is slidably connected to the inner wall of the long groove 12. By pushing the pull rod 11, the limiting rod 6 is moved, so that the worker can push the pull rod 11 into the round groove 5 and push the limiting rod 6 out of the slot 3. Then, through the sliding connection between the pull rod 11 and the long groove 12, the pull rod 11 can be placed on the inner wall of the long groove 12 and slide, so that the worker can push the limiting rod 6 into the round groove 5 to release the position restriction of the limiting rod 6 on the support rod 4.

[0023] Reference Figure 4 As shown in this embodiment: one end of the limiting rod 6 is provided with a rounded corner 13, and the end of the sliding groove 9 with a rounded corner 13 is smooth. When the limiting rod 6 is fully retracted into the circular groove 5, the limiting rod 6 is subjected to the elastic force of the spring 7, which moves the limiting rod 6 tightly against the inner wall of the frame 1. When the limiting rod 6 moves to the slot 3, the characteristics of the sliding groove 9 cause one end of the limiting rod 6 to gradually slide into the inner wall of the slot 3 through the inclined surface of the sliding groove 9, ensuring that the limiting rod 6 can be inserted into the slot 3 more smoothly under the elastic force of the spring 7.

[0024] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in this embodiment: extension blocks 14 are fixedly connected to both sides of the top of the support rod 4, and limit grooves 15 are opened on both sides inside the frame 1. The surface of the extension block 14 is slidably connected to the inner wall of the limit groove 15. Through the extension block 14 and the limit groove 15, when the support rod 4 moves up and down inside the frame 1, the extension block 14 moves with the support rod 4 on the inner wall of the limit groove 15, which restricts the movement trajectory of the support rod 4, so that the support rod 4 cannot be separated from the inside of the frame 1 and prevents the support rod 4 from rotating when it moves.

[0025] Reference Figure 2 and Figure 3 As shown in this embodiment: a long rod 16 is fixedly connected to one side of the bottom of the support rod 4, and a magnetic sliding rod 17 is slidably connected to the surface of the long rod 16. Several round holes 18 are opened on the surface of the handle body 8, and a magnetic block 19 is fixedly connected to the inner wall of the round hole 18. The operator pulls the handle body 8 out of the support rod 4 and places the magnetic sliding rod 17 on one side of the round hole 18. Then, the operator pushes the magnetic sliding rod 17 into the round hole 18 along the long rod 16, so that the magnetic block 19 and the magnetic sliding rod 17 generate mutual attraction, so that the magnetic block 19 and the magnetic sliding rod 17 magnetically adhere to each other, fixing the magnetic sliding rod 17 to the inner wall of the round hole 18. This restricts the position of the handle body 8 inside the support rod 4, allowing the operator to adjust the length of the handle body 8 according to their own needs.

[0026] Working principle: When the operator pushes the limiting rod 6 out of the slot 3, the support rod 4 can slide up and down inside the frame 1. When the operator pushes the limiting rod 6 to press the spring 7, the spring 7 is compressed by the limiting rod 6, thus storing force. After the operator slides the support rod 4 to the designated position inside the frame 1, the limiting rod 6 is released, releasing the force generated by the spring 7. This causes the spring 7 to rebound and push the limiting rod 6 into the inner wall of the slot 3, thereby fixing the position of the support rod 4. This allows the support rod 4 and the handle body 8 to be retracted into the frame 1, reducing the external length of the support rod 4 and making it easier to store and place the device. The self-retracting duster handle design not only improves usability but also... This design offers convenience and saves storage space. A T-shaped rod 10, placed within the slide groove 9, restricts the movement trajectory of the limiting rod 6 and limits the spring force range of the spring 7, preventing the spring 7 from ejecting the limiting rod 6 from the circular groove 5. This ensures the limiting rod 6 moves linearly along the T-shaped rod 10, improving the accuracy of the insertion of the limiting rod 6 into the slot 3. Pushing the pull rod 11 moves the limiting rod 6, allowing the operator to push the pull rod 11 into the circular groove 5, pushing the limiting rod 6 out of the slot 3. The sliding connection between the pull rod 11 and the long groove 12 allows the pull rod 11 to slide along the inner wall of the long groove 12, facilitating the operator to push the limiting rod 6 into the circular groove 5. The limiting rod 6 releases its positional restriction on the support rod 4. The end of the slide groove 9, with a rounded corner 13, is smooth and rounded. When the limiting rod 6 is fully retracted into the circular groove 5, it is subjected to the elastic force of the spring 7, causing it to move tightly against the inner wall of the frame 1. When the limiting rod 6 moves to the slot 3, the characteristics of the slide groove 9 cause one end of the limiting rod 6 to gradually slide through the inclined surface of the slide groove 9 into the inner wall of the slot 3, ensuring that the limiting rod 6 can smoothly engage with the slot 3 under the elastic force of the spring 7. Through the provided extension block 14 and the limiting groove 15, when the support rod 4 moves up and down inside the frame 1, the extension block 14 moves along the inner wall of the limiting groove 15, following the support rod 4. The movement trajectory of the support rod 4 is restricted to prevent it from detaching from the frame 1 and to prevent rotation during movement. The operator pulls the handle body 8 out of the support rod 4 and places the magnetic slide 17 on one side of the round hole 18. The operator then pushes the magnetic slide 17 into the round hole 18 along the long rod 16, causing the magnetic block 19 and the magnetic slide 17 to attract each other and magnetically attach to each other, fixing the magnetic slide 17 to the inner wall of the round hole 18. This restricts the position of the handle body 8 inside the support rod 4, allowing the operator to adjust the length of the handle body 8 according to their needs.
