[0024] Preferably, the width of the slot is set to correspond to the width of the signal line.

[0025] Compared with the prior art, the present invention has the following beneficial technical effects:

[0026] This invention provides a signal line length measuring fixture. Signal line support assemblies are fixed to both ends of a telescopic measuring tube. A spool is hung on the signal line support assembly, and the signal line is wound around the spool. The telescopic measuring tube has a groove along its long side. One end of the signal line is embedded in the groove and stretched along the tube's length within the groove. Graduation lines are sequentially arranged on the tube along the long side of the groove. By setting graduation lines on the telescopic measuring tube along the long side of the groove, accurate measurement of the signal line length can be achieved. With one end of the signal line embedded in the groove and stretched along the tube's length, the user can directly read the values ​​on the graduation lines to determine the exact length of the signal line, improving measurement accuracy and convenience.

[0027] Furthermore, the signal line support assembly includes a base and a support rod. The base is located at the end of the telescopic measuring tube, and its top surface is flush with the top surface of the telescopic measuring tube. The support rod is vertically mounted on the base, and the cable reel is hung on the support rod. The base design provides a stable support platform for the cable reel and support rod. By setting the top surface of the base flush with the top surface of the telescopic measuring tube, the stability of the entire measuring fixture during placement and use is ensured, preventing measurement errors caused by shaking or tilting. The vertical mounting of the support rod on the base allows the cable reel to be stably hung on it. Users can easily wind the signal line onto the reel or remove the signal line from the reel for measurement. This design simplifies the operation and improves work efficiency.

[0028] Furthermore, the support rod includes a first support rod and a second support rod; one end of the first support rod is fixed to the base, and the second support rod is horizontally fixed to the other end of the first support rod; the spool is hung on the second support rod, and the combination of the first and second support rods forms a stable support structure. The first support rod is vertically fixed to the base, providing a solid foundation for the entire support rod; the second support rod is horizontally fixed to the first support rod, providing a stable mounting point for the spool, enhancing the stability of the measuring fixture during use, and reducing measurement errors caused by shaking or tilting.

[0029] Furthermore, the base is provided with a groove that connects to the end of the wire slot, allowing the signal cable end to be inserted. The groove guides the signal cable, ensuring accurate alignment when inserted into the slot and preventing measurement errors caused by positional deviations. Users simply insert the signal cable end along the groove to easily embed it into the slot, improving operational accuracy and convenience.

[0030] Furthermore, the groove is equipped with an electronic component pressure plate for pressing the end of the signal line. The electronic component pressure plate can firmly press the end of the signal line into the groove, thereby ensuring that the signal line will not come out of the groove due to shaking or external force during the measurement process, thus ensuring the accuracy and stability of the measurement.

[0031] Furthermore, several signal line fixing components are sequentially arranged along the wire groove direction on the tube body of the telescopic measuring tube. The signal line fixing components have a U-shaped structure and are used to fix the signal line body. The signal line fixing components can firmly fix the signal line body to the tube body of the telescopic measuring tube, preventing the signal line from falling out of the wire groove due to shaking or external force during the measurement process, thereby enhancing the stability of the signal line and ensuring the accuracy and reliability of the measurement.

[0032] Furthermore, the telescopic measuring tube includes a first measuring tube, a second measuring tube, and a third measuring tube; both the first and third measuring tubes are hollow tubes; one end of the second measuring tube is embedded in the body of the first measuring tube, and the other end is embedded in the body of the third measuring tube; the wire groove is flush with the first, second, and third measuring tubes.

[0033] Furthermore, the groove depths of the first and third measuring tubes are the same and greater than the groove depth of the second measuring tube. By ensuring that the groove depths of the first and third measuring tubes are the same, the structural balance and stability of the measuring fixture can be maintained, effectively preventing measurement deviations caused by inconsistent groove depths.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0037] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, products, or devices.

[0038] The purpose of this invention is to provide a measuring fixture for signal line length, so as to solve the technical problem of how to improve the accuracy and convenience of measuring signal line length in the prior art.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings:

[0040] Example 1

[0041] See Figure 1 In one embodiment of this utility model, a measuring fixture for signal line length is provided, including a telescopic measuring tube 1; signal line support assemblies are fixed at both ends of the telescopic measuring tube 1; a wire spool 4 is hung on the signal line support assembly, and the signal line 5 is wound on the wire spool 4; a wire groove 6 is provided along the long side of the tube body of the telescopic measuring tube 1, one end of the signal line 5 is embedded in the wire groove 6, and is stretched along the tube body of the telescopic measuring tube 1 within the wire groove 6; graduation lines 9 are sequentially provided on the tube body of the telescopic measuring tube 1 along the long side of the wire groove 6.

[0042] Specifically, the signal line support assembly includes a base 2 and a support rod 3; the base 2 is located at the end of the telescopic measuring tube 1, and the top surface of the base 2 is flush with the top surface of the telescopic measuring tube 1; the support rod 3 is vertically mounted on the base 2, and the cable reel 4 is hung on the support rod 3.

[0043] Specifically, the support rod 3 includes a first support rod and a second support rod; one end of the first support rod is fixed to the base 2, and the second support rod is horizontally fixed to the other end of the first support rod; the spool 4 is hung on the second support rod.

[0044] Specifically, the base 2 has a groove that communicates with the end of the wire groove 6 for the insertion of the end of the signal line 5. An electronic component pressure plate 7 is provided on the groove to press down the end of the signal line 5.

[0045] The structural design principle of this embodiment is as follows:

[0046] The signal cable 5 is first coiled onto the reel 4. The design of the reel 4 allows for the orderly storage and release of the signal cable, facilitating quick access to the required length when needed. The reel 4 is hung on the second support rod, ensuring its stable suspension on the measuring fixture and preventing it from falling off due to shaking or external forces. When the length of the signal cable needs to be measured, the user unwinds the signal cable 5 from the reel 4 and inserts one end into the groove 6 of the telescopic measuring tube 1. The groove 6 allows the signal cable to be smoothly stretched along the long side of the tube, avoiding measurement errors caused by friction or bending. As the signal cable is stretched, the user can observe it moving along the tube of the telescopic measuring tube 1 and gradually extending to the desired length.

[0047] Example 2

[0048] See Figure 1 In one embodiment of this utility model, a measuring fixture for signal line length is provided, including a telescopic measuring tube 1; signal line support assemblies are fixed at both ends of the telescopic measuring tube 1; a wire spool 4 is hung on the signal line support assembly, and the signal line 5 is wound on the wire spool 4; a wire groove 6 is provided along the long side of the tube body of the telescopic measuring tube 1, one end of the signal line 5 is embedded in the wire groove 6, and is stretched along the tube body of the telescopic measuring tube 1 within the wire groove 6; graduation lines 9 are sequentially provided on the tube body of the telescopic measuring tube 1 along the long side of the wire groove 6.

[0049] Specifically, a number of signal line fixing members 8 are arranged sequentially along the direction of the wire groove 6 on the tube body of the telescopic measuring tube 1. The signal line fixing members 8 have a U-shaped structure and are used to fix the body of the signal line 5.

[0050] The structural design principle of this embodiment is as follows:

[0051] The telescopic measuring tube 1 is in an unstretched state, and its length is relatively short. The signal line 5 is neatly coiled on the reel 4, which is hung on the signal line support assemblies at both ends of the telescopic measuring tube 1. The signal line support assembly includes a base and a support rod, with the support rod vertically mounted on the base, providing a stable suspension point for the reel. Signal line fasteners 8 are evenly distributed along the tube body of the telescopic measuring tube 1, each fastener having a U-shaped structure, ready to receive and secure the signal line. When the length of the signal line 5 needs to be measured, the user unwinds one end of the signal line from the reel 4 and inserts it into the groove 6 at one end of the telescopic measuring tube 1. As the user gradually stretches the signal line, it moves smoothly along the groove 6 until the desired length is reached. During the stretching process, the signal line passes through each signal line fastener 8 in sequence. The fasteners, through their U-shaped structures, firmly hold the signal line body onto the tube body, preventing the signal line from detaching from the groove due to shaking or external force during measurement, thus ensuring the stability and accuracy of the measurement.

[0052] Example 3

[0053] See Figure 1 In one embodiment of this utility model, a measuring fixture for signal line length is provided, including a telescopic measuring tube 1; signal line support assemblies are fixed at both ends of the telescopic measuring tube 1; a wire spool 4 is hung on the signal line support assembly, and the signal line 5 is wound on the wire spool 4; a wire groove 6 is provided along the long side of the tube body of the telescopic measuring tube 1, one end of the signal line 5 is embedded in the wire groove 6, and is stretched along the tube body of the telescopic measuring tube 1 within the wire groove 6; graduation lines 9 are sequentially provided on the tube body of the telescopic measuring tube 1 along the long side of the wire groove 6.

[0054] Specifically, the telescopic measuring tube 1 includes a first measuring tube 10, a second measuring tube 11, and a third measuring tube 12; the first measuring tube 10 and the third measuring tube 12 are both hollow tubes; one end of the second measuring tube 11 is embedded in the tube body of the first measuring tube 10, and the other end is embedded in the tube body of the third measuring tube 12; the wire groove 6 is flush with the first measuring tube 10, the second measuring tube 11, and the third measuring tube 12.

[0055] The grooves 6 of the first measuring tube 10 and the third measuring tube 12 have the same depth, and both are greater than the groove depth of the second measuring tube 11. The first measuring tube 10, the second measuring tube 11, and the third measuring tube 12 are coaxially arranged. The width of the groove 6 corresponds to the width of the signal line 5.

[0056] The structural design principle of this embodiment is as follows:

[0057] In the initial state, the second measuring tube 11 is partially or completely embedded within the first measuring tube 10 and the third measuring tube 12, and the entire telescopic measuring tube is in a shorter state. The signal wire 5 is neatly coiled on the reel 4. When it is necessary to measure the length of the signal wire, one end of the signal wire is unwound from the reel 4 and embedded into the groove 6 at one end of the first measuring tube 10 or the third measuring tube 12. As the signal wire is stretched, it moves smoothly along the direction of the groove 6, passing through the first, second, and third measuring tubes in sequence. Since the width of the groove 6 corresponds to the width of the signal wire, the signal wire can move stably within the groove without falling off. During the stretching of the signal wire, the user can observe the position of the scale line 9 corresponding to the end of the signal wire to read the current length of the signal wire. Since the groove depths of the first and third measuring tubes are the same and both greater than the groove depth of the second measuring tube, it can be ensured that the signal wire remains on the same horizontal plane during the stretching process, avoiding measurement errors caused by inconsistent groove depths. When the signal wire is stretched to the required length, the user can stop stretching and perform necessary fixing operations. At this point, the length of the signal line has been accurately measured and recorded. Because the telescopic measuring tube has a retractable structure, the user can adjust the extension or retraction length of the second measuring tube within the first and third measuring tubes as needed, thereby enabling the measurement of signal lines of different lengths.

[0058] This utility model provides a signal line length measuring fixture that can accurately measure the size of the signal line. To ensure the accuracy of the measurement, the measuring fixture needs to be calibrated and maintained regularly to eliminate errors and maintain precision.

[0059] Several signal line fixing components 8 prevent the signal line 5 from moving or deforming during measurement. The design of the signal line fixing components 8 needs to be customized according to the shape, size, and material characteristics of the signal line 5 to ensure the stability and reliability of the fixing. At the same time, the signal line fixing components 8 also need to be easy to install and remove so that they can be quickly and easily replaced when changing parts.

[0060] This utility model provides a signal line length measuring fixture, which significantly changes the traditional measurement method. A single person can operate it independently to complete the measurement task, eliminating the need for multiple people, thus saving labor costs to a certain extent. Due to its reasonable structural design and simple operation, the measurement process is smoother, greatly shortening the measurement cycle and significantly improving production efficiency. This high efficiency is particularly prominent on mass production lines, saving enterprises a significant amount of time and costs.

[0061] By setting graduations on the telescopic measuring tube, accurate measurement data can be obtained with an extremely low error rate. This high-precision measurement not only ensures the stability of product quality but also provides reliable data support for enterprises, helping them to better control the production process and reduce scrap and rework rates. This fixture offers excellent flexibility, allowing for flexible configuration to meet different measurement needs. It can measure various signal cable lengths. This flexibility makes the fixture applicable to a wider range of industrial production applications, providing greater convenience for enterprises.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
