[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] refer to Figures 1 to 4 The belt disassembly and assembly tool in the embodiment of the utility model may include a circular mounting portion 10 and an arc-shaped guide block 20, wherein the circular mounting portion 10 can be used to be installed on the pulley 100, and when the circular mounting portion 10 is fixed to the pulley 100, the axis of the circular mounting portion 10 coincides with the axis of the pulley 100.

[0027] The arc-shaped guide block 20 is connected to the circumferential surface of the circular mounting portion 10. Figure 1As shown, the arc-shaped guide block 20 can be connected to the circular mounting portion 10 through the connecting portion 30. The connecting portion 30 is fan-shaped, and a circular arc surface is provided on one side connected to the circular mounting portion 10, so that the connecting portion 30 can be attached to and fixed on the circumferential surface of the circular mounting portion 10, thereby ensuring a tight connection between the connecting portion 30 and the circular mounting portion 10. A circular arc surface adapted to the contour of the circular arc-shaped guide block 20 is also provided on one side of the connecting portion 30 and the arc-shaped guide block 20, so that the circular arc-shaped guide block 20 and the connecting portion 30 are kept in a metal-wood connection.

[0028] like Figure 1 and Figure 2 As shown, a guide groove 21 is provided on the side of the arc-shaped guide block 20 away from the connecting portion 30, and the guide groove 21 penetrates the arc-shaped guide block 20 along the extension direction of the arc-shaped guide block 20, that is, both ends of the guide groove 21 are designed to be open. The bottom surface of the guide groove 21 has a guide surface 211 for contacting the belt 200, and the spacing between the first end 21a of the guide groove 21 and the circumferential surface of the circular mounting portion 10 is smaller than the spacing between the second end 21b of the guide groove 21 and the circumferential surface of the circular mounting portion 10, so that along the direction from the first end 21a of the guide groove 21 to the second end 21b, the height of the guide surface 211 gradually increases relative to the circumferential surface of the circular mounting portion 10.

[0029] There is a deflection angle between the extension direction of the guide groove 21 and the circumferential surface of the circular mounting portion 10, which can also be understood as the first end 21a opening and the second end 21b opening of the guide groove 21 are staggered. When the circular mounting portion 10 is mounted on the pulley 100, the first end 21a of the guide groove 21 can be aligned with the pulley groove of the pulley 100 for mounting the belt 200.

[0030] In addition, if Figure 2 As shown, the inner walls on both sides of the guide groove 21 are also provided with limiting surfaces 212, which can limit the belt 200 when the belt 200 is disassembled and assembled, so as to ensure that the belt 200 is kept in contact with the guide surface 211, and prevent the belt 200 from slipping out of the guide groove 21. The spacing between the two limiting surfaces 212 is greater than or equal to the width of the belt 200. It should be noted that when the spacing between the two limiting surfaces 212 is greater than the width of the belt 200, it is only slightly greater than the width of the belt 200.

[0031] The belt disassembly and assembly tool of this embodiment is used in combination with the belt 200 when disassembling the belt 200. Figure 2 and Figure 4, the circular mounting portion 10 can be first fixed on the pulley 100, at this time, the first end 21a of the guide groove 21 is aligned with the groove of the pulley, and then the pulley 100 is driven to rotate, and the rotation direction is the direction in which the second end 21b of the guide groove 21 points to the first end 21a. During the rotation process, the belt disassembly tool gradually contacts the belt 200. During the continuous radial advancement process, the guide groove 21 enters between the belt 200 and the pulley 100, and the belt 200 contacts the guide surface 211. At this time, the belt disassembly tool continues to rotate, and the belt 200 gradually moves away from the pulley 100 under the limiting action of the limiting surface 212 until it is disengaged, thereby completing the disassembly of the belt 200.

[0032] The belt disassembly and assembly tool of this embodiment is used in combination with the belt 200 when installing the belt 200. Figure 2 and Figure 5 , the belt 200 can be placed on the guide surface 211 and another auxiliary pulley (not shown in the figure), and the belt disassembly tool is fixed on the pulley 100. At this time, the guide surface 211 is located between the belt 200 and the pulley 100. Since the first end 21a of the guide groove 21 is aligned with the groove of the pulley, the part of the belt 200 located at the first end 21a of the guide groove 21 is aligned with the groove of the pulley. Then the belt disassembly tool is driven to rotate, and the rotation direction is the direction from the first end 21a of the guide groove 21 to the second end 21b. Under the limiting action of the limiting surface 212, the belt 200 gradually engages and extends along the radial direction of the pulley 100, and continues to rotate. The guide groove 21 gradually moves away from the belt 200 until it is completely out of the belt 200, thereby completing the installation of the belt 200.

[0033] In some embodiments, in order to facilitate the belt 200 to smoothly contact the guide surface 211 during the process of removing the belt 200, the first end 21a of the guide groove 21 can be in contact with the end surface of the pulley groove when the circular mounting portion 10 is fixed to the pulley 100. At this time, the guide surface 211 and the pulley groove are almost in the same plane, which can make it easy for the belt 200 to enter the guide groove 21. Similarly, when installing the belt 200, the belt 200 can also easily engage with the pulley groove, thereby installing the belt 200.

[0034] As mentioned above, there is a deflection angle between the extension direction of the guide groove 21 and the circumferential surface of the circular mounting portion 10, and the setting of the deflection angle can make it easier for the belt 200 to be removed from the pulley 100 during the process of removing the belt 200. As an optional embodiment, the deflection angle can range from 15° to 40°.

[0035] In some embodiments, reference Figure 6The circular mounting portion 10 is provided with a plurality of bolt holes. When the circular mounting portion 10 needs to be fixed to the pulley 100, it can be achieved by passing through a plurality of bolts 40 provided in the plurality of bolt holes, thereby maintaining a stable connection between the circular mounting portion 10 and the pulley 100. After the belt 200 is disassembled and assembled, the bolts 40 can also be removed to separate the circular mounting portion 10 from the pulley 100.

[0036] In addition, continue to refer to Figure 6 The belt disassembly and assembly tool in this embodiment may also include a rotary wrench 50. A rotary tool hole 11 is also provided at the center of the circular mounting portion 10. When the circular mounting portion 10 is fixed to the pulley 100, one end of the rotary wrench 50 may be inserted into the rotary tool hole 11 and relatively fixed with the rotary tool hole 11. Then, by pulling the rotary wrench 50, the circular mounting portion 10 is driven to rotate, thereby driving the pulley 100 to rotate together, so as to disassemble and assemble the belt 200.

[0037] The rotating tool hole 11 and the rotating wrench 50 are detachably connected, that is, when the circular mounting portion 10 needs to be driven to rotate, the rotating wrench 50 and the rotating tool hole 11 remain relatively fixed, and when the belt 200 is disassembled and assembled, the rotating wrench 50 is separated from the rotating tool hole 11. For example, as shown in the figure, the rotating tool hole 11 can be an inner square hole, and the cross-section of one end of the rotating wrench 50 extending into the rotating tool hole 11 is square. When the rotating wrench 50 extends into the rotating tool hole 11, the rotating wrench 50 engages with the inner square hole, so that the two remain relatively fixed.

[0038] Furthermore, the circular mounting portion 10 , the connecting portion 30 and the arc-shaped guide block 20 in this embodiment may be an integrated structure, so that the components are tightly connected to ensure the disassembly and assembly effect of the belt 200 .

[0039] The belt disassembly and assembly tool in the embodiment of the utility model can realize both the disassembly and installation of the belt, which not only realizes the lightness of the belt disassembly and assembly tool, but also improves the efficiency of belt disassembly and assembly. In addition, the main body of the belt disassembly and assembly tool is composed of only one structure, and the bolts and the rotary wrench can be universal parts, which makes the operation simpler and easier to understand, and is convenient for reducing the cost of tool training.

[0040] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
