[0026] The terms and words used in the following specification and claims are not limited to their literal meaning, but are used solely by the inventors to enable a clear and consistent understanding of this application. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this application is provided for illustrative purposes only and not for the purpose of limiting the application as defined in the appended claims and their equivalents.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] While ordinal numbers such as "first," "second," etc., will be used to describe various components, there is no limitation on which components are used herein. The term is used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0030] A versatile and illustrative shift cable disc, for reference. Figures 1 to 7 According to a preferred embodiment of the present invention, a versatile shift cable reel is provided, in which two cables are sleeved on the reel, and each cable has an insertion part at one end. The reel includes a reel body 10, the side of which has a cable groove 101 for placing the cables and two fixing parts 102 for placing the insertion parts. The fixing parts 102 are circular holes communicating with the cable groove 101. In use, the insertion part of each cable extends into the fixing part 102, while the cable is placed in the cable groove 101, making the cable taut. By pulling the cable, the reel body 10 rotates circumferentially, causing the shift shaft connected to the reel body 10 to rotate by a predetermined angle, thus providing a power transmission connection for shifting.

[0031] It should be noted that existing cable reels are only suitable for cable ropes of a specific diameter because the width of the cable groove 101 is constant and the bottom of the cable groove 101 is a concave arc surface corresponding to the radial dimension. This results in poor versatility.

[0032] Therefore, in this application, the versatile shift cable reel also includes several limiting plates 20. The bottom wall of the cable groove 101 is a V-shaped surface 1011. The limiting plates 20 are slidably arranged on both sides of the cable groove 101. When the cable is placed in the V-shaped surface 1011, the limiting plates 20 move towards or away from each other and are located on the side of the cable, abutting or separating from the cable.

[0033] It should be noted that, since the bottom wall of the cable guide groove 101 is a V-shaped surface 1011, when different diameter cables with circular cross-sections are placed in the cable guide groove 101, the two side liners of the cable are in contact with the V-shaped surface 1011. In addition, by causing the two limiting plates 20 located on both sides of the cable to move towards each other and to abut against the other two side liners of the cable, when the cable in a taut state is pulled, the friction between the cable and the cable guide groove 101 can drive the disc 10 to rotate circumferentially. Compared with the prior art, it has the advantages of being adaptable to cable diameters and having good versatility.

[0034] Furthermore, in this embodiment of the application, since the wire passage 101 extends in an arc direction, in order to adapt the limiting plate 20, both sides of the wire passage 101 have a plurality of arc-shaped mounting grooves 1012, each of the limiting plates 20 is arc-shaped, and each of the arc-shaped mounting grooves 1012 is provided with a limiting plate 20.

[0035] Furthermore, in order to guide the sliding process of the limiting plate 20, the two side walls of the through groove 101 are provided with a number of guide holes, each limiting plate 20 is provided with a number of guide rods 201, and each guide hole is provided with a guide rod 201.

[0036] Furthermore, to achieve the sliding and position fixing of the limiting plate 20, such as... Figure 5 As shown, the two side walls of the through groove 101 also have several threaded holes, and each threaded hole is threaded with a stop bolt 30. The bolt body end face of the stop bolt 30 has a ball head 301. One end of each limiting plate 20 has a hemispherical groove 202, and the ball head 301 is rotatably inserted into the hemispherical groove 202.

[0037] It should be noted that the radial dimension of the opening of the hemispherical groove 202 is smaller than the maximum radial dimension of the ball head 301, so that the ball head 301 cannot be dislodged from the hemispherical groove 202. At the same time, when the abutment bolt 30 rotates circumferentially, the ball head 301 rotates circumferentially within the hemispherical groove 202. It should also be pointed out that, in order to place the ball head 301 within the hemispherical groove 202, the maximum radial dimension of the hemispherical groove 202 can be made equal to the maximum radial dimension of the ball head 301. After the hemisphere of the ball head 301 extends into the hemispherical groove 202 a predetermined distance, metal is welded at the opening of the hemispherical groove 202 to make the radial dimension at the opening of the hemispherical groove 202 smaller than the maximum radial dimension of the ball head 301, thus preventing the ball head 301 from dislodging from the hemispherical groove 202. It should also be noted that when the abutment bolt 30 is tightened, the abutment bolt 30 moves toward the center plane of the wire passage 101, and drives the limiting plate 20 toward the cable placed in the wire passage 101; when the abutment bolt 30 is loosened, the abutment bolt 30 moves away from the center plane of the wire passage 101, and drives the limiting plate 20 away from the cable placed in the wire passage 101.

[0038] Furthermore, referring to Figure 6 and Figure 7 Since the side of the limiting plate 20 closest to the V-shaped surface 1011 is most likely to come into contact with the cable and is also most prone to wear, the side of the limiting plate 20 closest to the center plane of the cable groove 101 has a wear-resistant coating 205. The wear-resistant coating 205 is located on the side of the limiting plate 20 closest to the V-shaped surface 1011. Because the wear-resistant coating 205 is a mature technology, its specific structure will not be described in detail here. The wear-resistant coating 205 includes, but is not limited to, the wear-resistant coating 205 disclosed in patent document (CN104151993A).

[0039] Furthermore, since both the cable and the limiting plate 20 are vulnerable parts, in order to reduce replacement costs, such as Figure 4 As shown, the limiting plate 20 includes a base portion 203 and a contact portion 204. The contact portion 204 is detachably connected to the base portion 203. The guide rod 201 is fixedly connected to the base portion 203. The fixed connection method includes, but is not limited to, welding. The wear-resistant coating 205 is provided on the contact portion 204.

[0040] Specifically, to achieve a detachable connection between the contact portion 204 and the seat portion 203, such as Figure 4As shown, the contact portion 204 has a wear-resistant coating 205 on one side and a screw 206 that is threadedly connected to the seat portion 203. The screw 206 is located on the side of the contact portion 204 away from the wear-resistant coating 205.

[0041] In addition, such as Figure 4 As shown, the contact portion 204 has a thickened portion 2041 on one side of the wear-resistant coating 205. The thickened portion 2041 is located on the side of the contact portion 204 close to the seat portion 203, and the seat portion 203 has a notch 2031. The thickened portion 2041 is placed in the notch 2031, and glue is applied between the thickened portion 2041 and the notch 2031.

[0042] It should be noted that when the contact part 204 needs to be replaced, first unscrew the screw 206 on the contact part 204, and then use external force to separate the contact part 204 from the seat part 203. The adhesive is preferably a low-melting-point hot melt adhesive, including but not limited to the low-melting-point hot melt adhesive disclosed in patent document (CN213680528U). When it is difficult to remove the contact part 204, the contact part 204 can be heated first to soften the adhesive so that the contact part 204 can be removed. Then, replace it with a new contact part 204 that is not worn. It should be emphasized that since one side of the contact part 204 has the wear-resistant coating 205 and is in frequent contact with the cable, this side is not fixed with a screw 206. In addition, by providing the thickened part 2041 and the notch 2031, it is prevented that when applying adhesive to the contact part 204 or the notch 2031, the adhesive will overflow to the other side.

[0043] In summary, the versatile shift cable reel described in the embodiments of this application is explained, which provides the versatile shift cable reel with cable ropes that can be adapted to various rope diameters, and has advantages such as good versatility.

[0044] It is worth mentioning that, in the embodiments of this application, the versatile shift cable disc has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the versatile shift cable disc provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
