The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-6 The image shows an embodiment provided by this utility model.

[0023] This utility model embodiment provides a cable meter, including: (see attached drawing) Figure 1-2 As shown, the system includes a base 10, a limit wheel assembly 20, a measuring wheel 30, and an encoder 40. The limit wheel assembly 20 is mounted on the base 10, and the encoder 40 is mounted on one side of the base 10. The measuring wheel 30 is coaxially connected and fixed to the output shaft of the encoder 40 via a flat key. The encoder 40 is preferably an incremental rotary encoder. (Refer to the attached diagram.) Figure 5-6 As shown, the limiting wheel assembly 20 includes an upper wheel assembly 21 and a lower wheel assembly 22. The upper wheel assembly 21 and the lower wheel assembly 22 are arranged vertically at intervals, and a channel 23 for cable passage is formed between the upper wheel assembly 21 and the lower wheel assembly 22.

[0024] Specifically, refer to the appendix Figure 1-2 As shown, the base 10 includes an upper wheel frame 11 and a lower wheel frame 12 arranged parallel to each other. Both the upper wheel frame 11 and the lower wheel frame 12 are frame-like structures, integrally formed from aluminum alloy, which are high in strength and lightweight. The upper wheel assembly 21 is rotatably mounted in the upper wheel frame 11 via an axle, and the lower wheel assembly 22 is rotatably mounted in the lower wheel frame 12 via an axle. (Refer to the attached diagram.) Figure 1 The directions shown and the attached Figure 3-4 As shown, the bottom left side of the upper wheel frame 11 and the top left side of the lower wheel frame 12 are hinged together by a hinge or pin, allowing the upper wheel frame 11 to rotate around the hinge point. This is used to adjust the width of the channel 23 between the upper wheel assembly 21 and the lower wheel assembly 22, facilitating the installation of different cables. The right side wall of the encoder 40 near its rear end is hinged to the left side wall of the upper wheel frame 11 via a shaft 41. A torsion spring 42 is sleeved on the end of the shaft 41 away from the upper wheel frame 11. The torsion spring 42 is in a pre-compressed state and is located inside the housing of the encoder 40. The inner end of the torsion spring 42 is connected and fixed to the shaft 41, and the outer end of the torsion spring 42 abuts against the inner wall of the encoder 40 housing, providing elastic pressure for the rotation of the encoder 40. This is used to twist and press down the front end of the encoder 40, so that the measuring wheel 30 connected to it elastically abuts against the cable, ensuring stable friction between the measuring wheel 30 and the cable and preventing slippage.

[0025] After adopting the above-mentioned cable meter, the width of the cable channel 23 between the upper wheel assembly 21 and the lower wheel assembly 22 can be adjusted by setting the upper wheel frame 11 and the lower wheel frame 12 which are hinged to each other, so as to adapt to cables of different diameters. In addition, with the help of the pre-compressed torsion spring 42 sleeved on the shaft 41, the measuring wheel 30 is elastically pressed against the surface of the cable, which can flexibly adapt to cables of different diameters and surface conditions, and achieve stable measurement of cable length.

[0026] Further, refer to the appendix Figure 1 , 5 As shown in Figure 6, a limiting block 111 is provided at the bottom of the upper wheel frame 11. The lower end of the limiting block 111 abuts against the lower wheel frame 12 to limit the minimum width of the channel 23. The limiting block 111 is provided on the bottom edges of the left and right sides of the upper wheel frame 11, which parallels and separates the upper wheel frame 11 and the lower wheel frame 12. Under the action of the limiting block 111, the upper wheel frame 11 cannot rotate further toward the lower wheel frame 12, thereby limiting the minimum distance between the upper wheel assembly 21 and the lower wheel assembly 22, which is the minimum width of the cable channel 23.

[0027] In contrast, refer to Appendix Figure 5-6 As shown, a limit bracket 112 is provided on the right side wall of the upper wheel frame 11, and an adjusting screw 121 is provided on the right side wall of the lower wheel frame 12. The adjusting screw 121 is movably connected to the limit bracket 112, which is equivalent to a movable latch, and can limit the relative rotation angle between the upper wheel frame 11 and the lower wheel frame 12 within a certain range. This is used to adjust the maximum width of the channel 23 to accommodate cables with thicker diameters. Specifically, refer to the attached diagram. Figure 1-2 As shown, the limiting frame 112 is provided with an adjustment hole 113. The adjustment hole 113 is an elongated hole, and its length is greater than the diameter of the adjusting screw 121, leaving enough adjustment stroke. It is generally set to be able to adapt to wire diameter changes of 1-20mm, so that the adjusting screw 121 can have a certain degree of tilt freedom within the adjustment hole 113, thereby adapting to the angle change between the upper wheel frame 11 and the lower wheel frame 12. The adjusting screw 121 is provided with a quick-release nut 122. The lower end of the adjusting screw 121 is connected to the lower wheel frame 12, and its upper end passes upward through the adjustment hole 113 and is threadedly connected to the quick-release nut 122. The outer diameter of the quick-release nut 122 is greater than the minimum inner diameter of the adjustment hole 113. The inner end of the quick-release nut 122 abuts against the limiting frame 112. Tightening the quick-release nut 122 can lock the current width of the channel 23. After loosening, it can be quickly adjusted to adapt to the rapid switching of cable diameter. Furthermore, the quick-release nut 122 is a wing nut, which facilitates manual turning of the quick-release nut 122. If a cable is threaded through the channel 23, the width of the channel 23 between the upper wheel assembly 21 and the lower wheel assembly 22 can be adjusted by adjusting the position of the quick-release nut 122, thereby changing the degree of cable clamping. It can be understood that the width of the channel 23 refers to the diameter of the channel 23.

[0028] Specifically, refer to the appendix Figure 5-6As shown, the upper roller group 21 includes two spaced upper rollers 211, and the lower roller group 22 includes two spaced lower rollers 221. The upper rollers 211 and lower rollers 221 have the same shape, similar to pulleys, and have V-shaped, U-shaped or semi-circular grooves in the middle of their wheel surfaces. These grooves can limit the cable to the middle of the wheel surfaces of the upper rollers 211 and lower rollers 221 to prevent the cable from deviating. The two upper rollers 211 are located on the outside of the two lower rollers 221, and the distance between the two upper rollers 211 is greater than the distance between the two lower rollers 221, forming a "wider at the top and narrower at the bottom" guide structure to ensure the stability of the cable when it travels. Preferably, the difference between the distance between the two upper rollers 211 and the distance between the two lower rollers 221 is equal to the diameter of the upper roller 211 or the lower roller 221. For example, the diameter of the upper roller 211 / lower roller 221 is 40mm, the distance between the two upper rollers 211 is 80mm, and the distance between the two lower rollers 221 is 40mm.

[0029] Specifically, refer to the appendix Figure 1 , 3 As shown, the measuring wheel 30 is located between the two upper rollers 211. The axis of the measuring wheel 30 is perpendicular to the direction of cable travel. When the measuring wheel 30 comes into contact with the cable surface, the axis of the measuring wheel 30 and the axes of the two upper rollers 211 are basically in the same horizontal plane, so that the pressure of the measuring wheel 30 on the cable is evenly distributed, avoiding the cable from being deviated by force on one side, and further improving the measurement accuracy.

[0030] Further, refer to the appendix Figure 1 , 4 As shown, the measuring wheel 30 is covered with a flexible sleeve 31. The sleeve 31 is 2-5mm thick and covers the entire circumference of the measuring wheel 30. The sleeve 31 is made of an elastic material, such as silicone or rubber. The elastic sleeve 31 can increase the coefficient of friction with the cable surface and reduce slippage. On the other hand, it can buffer the pressure of the measuring wheel 30 on the cable and avoid damage to the cable sheath. It is especially suitable for fragile cables with PVC or rubber sheaths.

[0031] This utility model embodiment effectively solves the pain points of traditional meter counters, such as slippage, poor wire diameter compatibility, and easy cable damage, through the coordinated design of "elastic contact measuring wheel 30 + adjustable width limiting wheel group 20 + flexible protective wheel sleeve 31". Its compact structure, convenient operation, and high measurement accuracy make it widely applicable in cable production, municipal construction, power maintenance, and other scenarios. It is suitable for measuring various wire diameters, from thin optical fibers to thick power cables, balancing practicality and durability, and has significant market application value.

[0032] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this 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 specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
