[0002] Cables are a general term for items such as optical cables and electrical cables. Cables have many uses, mainly for control installation, connecting equipment, and transmitting power. They are a common and indispensable item in daily life. In order to ensure that the cable length is sufficient for subsequent installation and that the cable meets the specified length requirements, and to avoid low installation efficiency due to insufficient cable length, the length of the cable is usually measured by a cable length measuring device.

[0003] Existing cable length measurement typically uses mechanical meter counters, which drive the metering wheel to rotate through the friction of the cable, thereby measuring the cable length. When measuring cables of different diameters, insufficient contact friction between the fixedly installed metering wheel and the cable can easily cause the metering wheel to slip, reducing the accuracy of cable length measurement and failing to meet usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision intelligent cable length measuring instrument to solve the problem mentioned in the background art that existing cable length measurement usually uses a mechanical meter counter, which drives the meter counter wheel to rotate through the friction of the cable to achieve cable length measurement. When measuring cables of different diameters, the contact friction between the fixedly installed meter counter wheel and the cable is insufficient, which can easily cause the meter counter wheel to slip, reduce the accuracy of cable length measurement, and fail to meet the usage requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision intelligent cable length measuring instrument, comprising a base and a cable, wherein a first mounting frame, a second mounting frame, and two columns are fixed on the base; a first support roller is rotatably mounted on the inner side of the first mounting frame, and a second support roller is rotatably mounted on the inner side of the second mounting frame, with the first and second support rollers flush; a first mounting groove is provided on the first mounting frame, and a slider is slidably connected inside the first mounting groove; a pressure roller is provided above the first support roller, and the pressure roller is rotatably connected to the slider; and a second mounting groove is provided on the second mounting frame.

[0014] 1. This utility model device, through the arrangement of a second connecting frame, a measuring wheel, a scale, a pointer, a counter, and a second electric telescopic rod, allows the measuring wheel to contact the cable.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-7 This utility model provides an embodiment of a high-precision intelligent cable length measuring instrument, comprising a base 1 and a cable 24. A first mounting bracket 2, a second mounting bracket 7, and two columns 25 are fixed on the base 1. A first support roller 3 is rotatably mounted on the inner side of the first mounting bracket 2, and a second support roller 8 is rotatably mounted on the inner side of the second mounting bracket 7, with the first support roller 3 and the second support roller 8 being flush. A first mounting groove 4 is provided on the first mounting bracket 2, and a slider 5 is slidably connected inside the first mounting groove 4. A pressure roller 6 is provided above the first support roller 3, and the pressure roller 6 is rotatably connected to the slider 5. A second mounting groove 9 is provided on the second mounting bracket 7, and a first connecting bracket 10 is slidably connected inside the second mounting groove 9. A feeding roller 13 is rotatably mounted below the first connecting bracket 10, and the feeding roller 13 is positioned above the second support roller 8. The columns 25 are internally configured with… A telescopic cavity 26 is provided. A second connecting frame 15 is provided above the column 25. The lower end of the second connecting frame 15 extends into the interior of the telescopic cavity 26 and is slidably connected to the column 25. A measuring wheel 16 is rotatably mounted on the inner side of the second connecting frame 15. A pointer 18 is provided on one side of the second connecting frame 15 and is fixedly connected to the measuring wheel 16. A third connecting frame 19 is fixed on one side of the second connecting frame 15. A counter 20 is fixed on the inner side of the third connecting frame 19 and is located on one side of the pointer 18. A second electric telescopic rod 27 is fixed inside the telescopic cavity 26 and is located below the second connecting frame 15. The telescopic end of the second electric telescopic rod 27 is connected to the second connecting frame 15. A scale 17 is fixed on the outer wall of the second connecting frame 15, and the center of the scale 17 coincides with the center of the measuring wheel 16.

[0026] In use: The cable 24 is passed through the first mounting frame 2, the second connecting frame 15, and the second mounting frame 7 in sequence. The cable 24 rests on the first support roller 3 and the second support roller 8. The pressure roller 6 and the feeding roller 13 contact the upper end of the cable 24. The cable 24 is clamped from both sides of the measuring mechanism, so that the cable 24 is in a straight state. The second electric telescopic rod 27 is driven to drive the second connecting frame 15 to descend. The descending second connecting frame 15 drops the measuring wheel 16 to contact the cable 24, and the cable 24 at the connection point droops slightly. When the cable 24 is conveyed, the contact friction between the measuring wheel 16 and the cable 24 is used to drive the measuring wheel 16 to rotate. The rotating measuring wheel 16 drives the pointer 18 to rotate synchronously. The counter 20 measures the number of rotations of the pointer 18. The length of one rotation of the measuring wheel 16 is constant. Combined with the position of the pointer 18 pointing to the scale 17, the length of the cable 24 is accurately measured.

[0027] Please see Figure 6 The outer surface of the measuring wheel 16 is provided with an anti-slip coating 23. The anti-slip coating 23 increases the friction of the outer surface of the measuring wheel 16, which can effectively prevent the measuring wheel 16 from slipping and improve the measurement accuracy of the cable 24 length.

[0028] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 A motor 11 is fixed to one side of the first connecting frame 10, and the telescopic end of the motor 11 is connected to one end of the feeding roller 13. A spring 21 is provided inside the first mounting groove 4, and the spring 21 is located above the slider 5. The two ends of the spring 21 are fixedly connected to the first mounting frame 2 and the slider 5, respectively. A first electric telescopic rod 14 is fixed above the second mounting frame 7, and the telescopic end of the first electric telescopic rod 14 is connected to the upper end of the first connecting frame 10. Roller grooves 12 are provided on the inner walls of the first mounting groove 4 and the second mounting groove 9. Ball bearings 22 are rolled on the side walls of the slider 5 and the first connecting frame 10. The ball bearings 22 are correspondingly arranged with the roller grooves 12, and the ball bearings 22 are rolledly connected with the first mounting frame 2 and the second mounting frame 7. The spring 21 applies a downward pushing force to the slider 5, so that the pressure roller 6 is in close contact with the cable 24. The first electric telescopic rod 14 drives the first connecting frame 10 to rise and fall, adjusting the distance between the feeding roller 13 and the second support roller 8, which can drive the conveying of cables 24 of different diameters to meet the length measurement of cables 24 of different diameters.

[0029] Working principle: The cable 24 is passed sequentially through the first mounting frame 2, the second connecting frame 15, and the second mounting frame 7. The cable 24 rests on the first support roller 3 and the second support roller 8. The spring 21 applies a downward pushing force to the slider 5, making the pressure roller 6 in close contact with the cable 24. The first electric telescopic rod 14 drives the first connecting frame 10 to descend, and the feeding roller 13 contacts the upper end of the cable 24, clamping the cable 24 from both sides of the measuring mechanism, so that the cable 24 is in a taut state. The second electric telescopic rod 27 drives the second connecting frame 15 to descend, and the descending second connecting frame 15 will... The measuring wheel 16 falls down and contacts the cable 24, causing the cable 24 at the connection point to sag slightly. The motor 11 is turned on to drive the feeding roller 13 to rotate. As the feeding roller 13 rotates, it applies tension to the cable 24. When the cable 24 is being conveyed, the contact friction between the measuring wheel 16 and the cable 24 drives the measuring wheel 16 to rotate. The rotating measuring wheel 16 drives the pointer 18 to rotate synchronously. The counter 20 measures the number of rotations of the pointer 18. The length of one rotation of the measuring wheel 16 is constant. Combined with the position of the pointer 18 pointing to the scale 17, the length of the cable 24 is accurately measured.
