In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0024] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] The embodiment of the present application provides a belt fixing clip 100 and a belt winding device including the belt fixing clip 100. Figure 1 and Figure 2, the belt winding device also includes a limiting reel 110, a driving motor 120 and a rotating shaft 130. Among them, there are two limiting reels 110, which are arranged oppositely and at intervals, and are used to limit the belt 200 during the process of winding the belt 200 into a disk to prevent the belt 200 from deflecting. The shape of the limiting reel 110 is not limited, and it can be a flat plate structure of a circular, square or other shapes. The rotating shaft 130 is set through the center of the limiting reel 110, and a through hole is opened in the center of the limiting reel 110 for the rotating shaft 130 to pass through. The rotating shaft 130 and the limiting reel 110 can be connected by a rolling bearing, so that the rotating shaft 130 remains stable during rotation and does not affect the limiting reel 110. The output end of the driving motor 120 is connected to the rotating shaft 130 to provide power for the rotating shaft 130 to rotate. The belt fixing clamp 100 is sleeved on the rotating shaft 130 and clamped between the two limiting reels 110. The belt fixing clamp 100 is used to fix the end of the belt 200 so that when the driving motor 120 drives the rotating shaft 130 to rotate, the rotating shaft 130 drives the belt fixing clamp 100 to rotate, thereby causing the belt 200 to be wound into a disk between the two limiting reels 110.

[0026] See also Figures 3 to 5 The belt fixing clip 100 of the embodiment of the present application includes a fixing member 10 and a buckle 20. The fixing member 10 is a cylindrical structure, and the buckle 20 is detachably arranged on the inner side of the fixing member 10. The inner side surface of the belt 200 is provided with a belt tooth portion 201, and one side of the buckle 20 is provided with a wheel tooth portion 21 meshing with the belt tooth portion 201. The inner side wall of the fixing member 10 provides a clamping surface 11 opposite to the wheel tooth portion 21, and a belt cavity 30 is formed between the clamping surface 11 and the wheel tooth portion 21. The fixing member 10 is provided with an opening 12 connecting the belt cavity 30 with the outside. One end of the belt 200 is meshed and connected with the wheel tooth portion 21 through the belt tooth portion 201 to be fixed in the belt cavity 30, and the other end extends to the outside of the fixing member 10 through the opening 12, thereby achieving the fixing of the end of the belt 200. The belt fixing clip 100 is suitable for fixing a belt 200 with a belt tooth portion 201 structure.

[0027] Preferably, the shape and size of the belt cavity 30 are adapted to the shape and size of the end of the belt 200. That is, when the belt tooth portion 201 on the inner side of the end of the belt 200 is meshed with the wheel tooth portion 21 on the buckle 20, the outer side of the belt 200 is in contact with the clamping surface 11. In this way, the belt tooth portion 201 and the wheel tooth portion 21 are fully meshed, and the belt 200 will not be loose relative to the buckle 20 in the thickness direction, so that the belt 200 can be prevented from slipping, de-toothing, etc., and the fixing effect of the belt fixing clip 100 on the end of the belt 200 is enhanced.

[0028] Furthermore, in the circumferential direction of the fixing member 10, the extension length of the belt cavity 30 is greater than half of the circumference of the inner wall of the fixing member 10. In this way, by increasing the circumferential extension length of the belt cavity 30 as much as possible, the length of the end of the belt 200 clamped in the belt cavity 30 is increased, and the number of meshing teeth of the belt tooth portion 201 and the wheel tooth portion 21 can be increased, and the frictional traction between the belt 200 and the buckle 20 is increased, so as to prevent the belt 200 from slipping out of the belt cavity 30.

[0029] In the embodiment of the present application, the fixing member 10 is an annular cylindrical structure, and correspondingly, the clamping surface 11 is an arc surface. That is, the end of the belt 200 is bent in an arc shape and clamped in the belt cavity 30. In this way, the damage to the belt 200 itself caused by the bending of the belt 200 can be reduced, and the service life of the belt 200 can be increased. Of course, in other embodiments, the fixing member 10 can also be a rectangular cylindrical structure, a hexagonal cylindrical structure, etc., which can achieve similar effects to the above-mentioned embodiments, and are not limited here.

[0030] In order to achieve the best fixing effect, the axial width of the buckle 20 needs to be greater than or equal to the width of the belt 200, so that the belt tooth portion 201 at the end of the belt 200 is fully meshed in the wheel tooth portion 21, and the friction traction between the belt tooth portion 201 and the wheel tooth portion 21 is enhanced. More preferably, the axial width of the fixing member 10 needs to be greater than or equal to the axial width of the buckle 20, so that the clamping surface 11 fully covers the part of the belt 200 located in the belt cavity 30, increasing the contact area between the clamping surface 11 and the outer side of the belt 200, so that the belt 200 is evenly stressed during the process of being pulled and deformed, reducing the damage to the belt 200 and increasing the service life of the belt 200.

[0031] In order to prevent the buckle 20 from rotating relative to the fixing member 10 and causing the end of the belt 200 to be forced out, in the illustrated embodiment, the buckle 20 is a quasi-circular structure, and a toothed portion 201 is provided on one side of the buckle 20, and the other side of the buckle 20, that is, the side of the buckle 20 relative to the gear portion 21, is engaged with the inner side wall of the fixing member 10 to limit the buckle 20 from rotating relative to the fixing member 10. More specifically, a block 13 is convexly provided on the inner side wall of the fixing member 10, and a groove 22 that is slidably matched with the block 13 is concavely provided on the side of the buckle 20 relative to the gear portion 21, and the block 13 and the groove 22 are both extended along the axial direction of the fixing member 10. In this way, the relative rotation of the buckle 20 and the fixing member 10 is limited by the engagement of the groove 22 and the block 13, so as to prevent the belt 200 from coming out. At the same time, during the winding process of the belt 200, the rotating shaft 130 needs to drive the belt fixing clamp 100 as a whole, that is, the fixing member 10 and the buckle 20 to rotate simultaneously to realize the winding of the belt 200. Through the cooperation between the card slot 22 and the card block 13, the buckle 20 can drive the fixing member 10 to rotate synchronously when rotating. It can be understood that in other embodiments, the positions of the card block 13 and the card slot 22 can also be interchanged, or the buckle 20 and the fixing member 10 can also be bolted, pinned, etc., as long as the buckle 20 and the fixing member 10 do not rotate relative to each other.

[0032] Preferably, in order to facilitate the installation of the belt 200 into the belt cavity 30, the slot 22 extends to the two ends of the buckle 20 in the axial direction of the fixing member 10, so that the buckle 20 can slide in or out from the axial ends of the fixing member 10. In the process of installing the belt 200 into the belt cavity 30, the outer side of the belt 200 can be first fitted with the clamping surface 11, and then one end of the slot 22 on the buckle 20 is aligned with the block 13 on the fixing member 10, and the position of the belt 200 is adjusted so that the belt tooth portion 201 corresponds to the wheel tooth portion 21, and then the buckle 20 is slid into the inner side of the fixing member 10 along the slot 22 to complete the fixing of the end of the belt 200. The fixing process is convenient and quick, and the belt 200 is easy to disassemble and assemble, which is conducive to the replacement, maintenance and other operations of the belt 200, and at the same time, it will not cause damage to the belt 200.

[0033] The buckle 20 is provided with a connection hole 23, which is used for the shaft 130 to pass through to drive the buckle 20 to rotate. The shaft 130 and the connection hole 23 can be movably connected to facilitate the disassembly and assembly of the buckle 20 and the fixing member 10 and the belt 200. The two limit reels 110 are clamped on both sides of the axial direction of the belt fixing clamp 100 to limit the position of the buckle 20 on the shaft 130. The connection hole 23 is preferably a waist-shaped hole, and can also be a non-circular hole such as a polygonal hole.

[0034] In summary, the belt fixing clamp of the embodiment of the present application, by providing the fixing member 10 and the buckle member 20, can fix the end of the belt 200 in the belt cavity 30 formed by the clamping surface 11 of the fixing member 10 and the gear portion 21 of the buckle member 20, with good fixing effect, convenient disassembly and assembly of the belt 200, and convenient for inspection and maintenance, while avoiding damage to the belt 200 caused by the fixing method such as punching in the prior art. The belt winding device of the present application adopts all the technical solutions of the aforementioned embodiments, and therefore has at least all the beneficial effects brought by the technical solutions of the aforementioned embodiments, which will not be repeated here one by one.

In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0036] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
