Description

Technical Field

[0001] This utility model relates to the field of folding handle technology, and in particular to a space-saving structure with a foldable handle. Background Technology

[0002] Handles are components installed on various objects for opening, closing, or gripping operations. They are made of various materials and come in different shapes to meet different needs. Their design focuses on ergonomics to ensure comfort during use. To facilitate adjustment of handles and save space, a foldable handle space-saving structure is needed.

[0003] Foldable handles are a space-saving design that allows handles to be folded up when not in use, reducing space occupation. This structure achieves folding through mechanisms such as hinges and pivots, and is widely used in furniture, vehicles, etc. It saves space and is easy to carry and store, improving the flexibility and convenience of use.

[0004] Currently available foldable handles consist of a grip and a connecting tube. However, when used in narrow spaces or small structures, these retractable handles take up a lot of space and are difficult to operate. Existing technologies replace the connecting rod of the handle with a retractable tube, and fold the handle by extending and retracting the tube to save space. However, in actual use, the extension and retraction of the tube causes it to gradually taper at the end, which makes the handle prone to bending, deformation, or even breakage after heavy use and long-term use, thus reducing the stability of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a space-saving foldable handle structure, which aims to improve the problem that the space-saving foldable handle structure in the prior art is easily broken during use due to the telescopic tube.

A U-shaped block is rotatably connected to the outer side of the spring telescopic block. A plug-in block is fixedly connected to the outer side of the U-shaped block. Plug-in holes are provided on the outer circumference of the U-shaped cover. The outer side of the plug-in block passes through the plug-in holes. The top of the rotating ring is rotatably connected to the U-shaped cover.

[0010] As a further description of the above technical solution:

[0011] The protective assembly includes a mounting bracket, two of which are fixedly connected to the front and rear sides of the outer side of the positioning cover, and a protective pad is fixedly connected to the outer side of the mounting bracket.

[0032] 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.

[0033] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a space-saving structure with a foldable handle, including a positioning cover 1 and a belt 6. The front and rear sides of the interior of the positioning cover 1 are fixedly connected with connecting plates 4. A U-shaped cover 9 is provided on the left side of the positioning cover 1. A protective component is provided on the outside of the positioning cover 1. A positioning mechanism 2 is provided on the inside of the U-shaped cover 9. The positioning mechanism 2 is used to disassemble and fix the device.

[0034] Rotating wheels 5 are rotatably connected to the left and right sides of the connecting plate 4. Multiple rotating wheels 5 are connected to each other by corresponding belts 6. The belts 6 can drive the rotating wheels 5 to rotate synchronously. A bidirectional threaded rod 3 is fixedly connected to the rear side of the rotating wheel 5 through the connecting plate 4. A movable plate 7 is threaded to the front and rear sides of the bidirectional threaded rod 3. Rotating the bidirectional threaded rod 3 can drive the movable plate 7 to move. A spring telescopic plate 8 is rotatably connected to the inner side of the movable plate 7. The outer side of the spring telescopic plate 8 is rotatably connected to the U-shaped cover 9. A mounting post 10 is engaged on the inner side of the U-shaped cover 9. Rotating the spring telescopic plate 8 can push the U-shaped cover 9 and the mounting post 10 on it to move.

[0035] Specifically, the belt 6 drives the rotating wheel 5 to rotate, which in turn drives the two-way threaded rods 3 on both sides to rotate, causing the moving plate 7 to move back and forth along the inner side of the positioning cover 1. The movement of the moving plate 7 drives the spring telescopic plate 8 to rotate. The spring telescopic plate 8 extends and retracts itself while rotating, pushing the U-shaped cover 9 to move. This makes the device easy to hold when in use, and the spring telescopic plates 8 on both sides enhance the structural strength and stability of the device.

[0036] Reference Figure 1 , Figure 2 and Figure 5 The positioning mechanism 2 includes a rotating ring 201, which is rotatably connected to the outside of the mounting column 10. A cross plate 202 is fixedly connected to the right side of the rotating ring 201. Spring telescopic blocks 203 are rotatably connected to the inside of the cross plate 202. A U-shaped block 205 is rotatably connected to the outside of the spring telescopic block 203. A plug-in block 204 is fixedly connected to the outside of the U-shaped block 205. A plug-in hole 206 is provided on the outside of the U-shaped cover 9. The plug-in block 204 passes through the plug-in hole 206. The top of the rotating ring 201 is rotatably connected to the U-shaped cover 9.

[0037] Specifically, rotating the rotating ring 201 synchronously drives the cross plate 202 to rotate. The rotation of the cross plate 202 will drive the spring telescopic block 2035 and the U-shaped block 20 to rotate synchronously, thereby driving the insertion block 204 to move. When the insertion block 204 moves out of the insertion hole 206 of the U-shaped cover 9, it can realize the quick and stable disassembly and fixation between the mounting post 10 and the U-shaped cover 9.

[0038] Reference Figure 2 , Figure 3 and Figure 4 The protective components include mounting brackets 12, with two mounting brackets 12 fixedly connected to the front and rear sides of the outer side of the positioning cover 1, respectively. A pad 13 is fixedly connected to the outer side of the mounting bracket 12, which improves the grip comfort of the device. A knob 11 is rotatably connected to the outer perimeter of the positioning cover 1. The outer side of the knob 11 passes through the positioning cover 1 and is fixedly connected to the rotating wheel 5. Rotating the knob 11 can synchronously drive the rotating wheel 5 to rotate. A mounting plate 17 is fixedly connected to the inner left side of the positioning cover 1. A hollow ring 18 is fixedly connected to the inner side of the mounting plate 17. The hollow ring 18 is slidably connected to the U-shaped cover 9. The mounting plate 17 and the hollow ring 18 can improve the protection and dustproof effect of the positioning cover 1.

[0039] Specifically, the pad 13 fixed by the mounting bracket 12 can improve the grip comfort and friction of the device, making it easier to operate and rotate the device. The rotating knob 11 can be turned synchronously to drive the rotating wheel 5 to rotate. The mounting plate 17 and the U-shaped cover 9 on it can protect the inside of the positioning cover 1. The hollow ring 18 can improve the stability of the U-shaped cover 9 when moving.

[0040] Reference Figure 1 , Figure 3 and Figure 5 The mounting post 10 has a mounting opening 19 on its left side, and a threaded groove 20 is provided on the inner side of the mounting opening 19. The device can be fixed through the threaded groove 20 on the inner side of the mounting opening 19, and the threaded groove 20 facilitates the installation and fixation of the device. The upper and lower sides of the right end of the inner wall of the positioning cover 1 are provided with sliding grooves 16. The moving plate 7 is slidably connected to the sliding grooves 16, which can improve the stability of the moving plate 7 when moving. Multiple indicator grooves 15 are provided on the outer side of the mounting post 10. An indicator block 14 is fixedly connected to the top of the rotating ring 201. The position of the rotating ring 201 can be easily determined by the indicator block 14 indicating the corresponding indicator groove 15.

[0041] Specifically, the threaded groove 20 in the mounting port 19 facilitates the installation of the device on additional equipment. The sliding connection between the slide groove 16 and the moving plate 7 improves the stability of the moving plate 7 during movement. By observing the corresponding indicator block 14 through the indicator groove 15, the position of the rotating ring 201 can be determined to determine whether the mounting column 10 is now fixed.

[0042] Working principle: Before using the device, the belt 6 drives the rotating wheel 5 to rotate synchronously, which in turn drives the two-way threaded rods 3 on both sides to rotate synchronously. This causes the moving plate 7 to move back and forth along the inner side of the positioning cover 1. As the moving plate 7 moves, it drives the spring telescopic plate 8 to rotate. The rotation and extension of the spring telescopic plate 8 can push the U-shaped cover 9 to move. When in use, the device can be unfolded for easy gripping, and the structural strength and stability can be improved by the spring telescopic plates 8 on both sides.

[0043] Furthermore, by rotating the rotating ring 201, the cross plate 202 can be rotated synchronously. At this time, as the cross plate 202 rotates, it can drive the multiple spring telescopic blocks 203 on the inner side to rotate synchronously. As the spring telescopic blocks 203 move and extend and retract, they will push the U-shaped block 205 to move, thereby driving the plug-in block 204 to move. When the plug-in block 204 moves, it is discharged from the corresponding plug-in hole 206 on the U-shaped cover 9, thereby enabling the mounting post 10 and the U-shaped cover 9 to be quickly and securely disassembled and fixed.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
