Description

Technical Field

[0001] This utility model relates to the field of cables, specifically a cable length measuring device. Background Technology

[0002] Cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on. They are all composed of single or multiple strands of conductors and insulation layers, used to connect circuits, electrical appliances, etc.

[0003] The length of the cable is measured during laying and production. When producing and laying cables of different specifications at the same time, the distance between the measuring wheels needs to be repeatedly adjusted, which reduces the efficiency of production and laying.

[0004] To address this, we propose a cable length meter that can adapt to different cable diameter specifications. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cable length meter, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the specific technical solution adopted by this utility model is as follows:

[0007] A cable length meter includes a concave base, inside which a fixed straightening wheel seat is installed. Supports are provided on both sides of the concave base via columns, and an adjustment transmission assembly is installed on the support. The bottom end of the adjustment transmission assembly is connected to a movable straightening wheel seat via an elastic adjustment arm. The movable straightening wheel seat is movably positioned above the fixed straightening wheel seat through a positioning hole. The fixed straightening wheel seat and the movable straightening wheel seat are provided with two rows of identical guide wheels via a rotating shaft, and one of the guide wheels in the lower row is designated as the measuring wheel.

[0008] Furthermore, the adjustment transmission assembly includes an adjustment frame and an adjustment screw. An adjustment threaded cylinder is installed on the middle part of the adjustment frame, and the adjustment screw is installed on the middle part of the bracket, with its lower end threadedly connected to the adjustment threaded cylinder. An adjustment handle is provided on the top of the adjustment screw.

[0009] Furthermore, the elastic adjusting arm is installed at the bottom of both ends of the adjusting frame, and the bottom end of the elastic adjusting arm is fixedly connected to the movable straightening wheel seat. The elastic adjusting arm includes a telescopic rod, and a compression spring is sleeved around the telescopic rod.

[0010] Furthermore, the fixed straightening wheel seat is provided with a positioning rod, which slides through the connecting positioning hole.

[0011] Furthermore, the axle of the measuring wheel extends out of the concave base and connects to a mechanical counter. The mechanical counter is mounted on the outer wall of the concave base via a mounting bracket and is used to read the number of rotations of the measuring wheel.

[0012] Furthermore, the measuring wheel's shaft is fixedly provided with a gear on the outer side of the concave base, and a limiting structure for preventing the gear from rotating in the opposite direction is installed on the outer wall of the concave base.

[0013] Furthermore, the limiting structure includes a limiting plate, one end of which is mounted on the outer wall of the concave base via a pin, and the other end of which abuts against the lower end of the gear. A limiting stop is provided above the limiting plate, which is fixed to the outer wall of the concave base and fits against the limiting plate. A support rod is provided below the limiting plate, which is fixed to the outer wall of the concave base, and a spring is provided on the support rod to elastically support the limiting plate.

[0014] This utility model has the following features and beneficial effects:

[0015] This invention adjusts the vertical displacement of the upper row of guide wheels by adjusting the transmission component. Under the elastic potential energy of the compression spring of the elastic adjusting arm, the upper row of guide wheels keeps in contact with the lower row of guide wheels to clamp the outer surface of the cable. This allows cables of different diameters to move between the upper and lower rows of guide wheels, improving work efficiency and applicability, and facilitating the metering and laying of cables of different diameters. By using the metering wheel in conjunction with the length counter, it can achieve the effect of accurately laying cables according to preset length data. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0025] like Figure 1-4 As shown, a cable length meter includes a concave base 1, inside which a fixed straightening wheel seat 2 is installed. Supports 12 are provided on both sides of the concave base 1 via columns 11. An adjustment transmission assembly is installed on the supports 12. The bottom end of the adjustment transmission assembly is connected to a movable straightening wheel seat 4 via an elastic adjustment arm 51. The movable straightening wheel seat 4 is movably positioned above the fixed straightening wheel seat 2 via a positioning hole 41. The fixed straightening wheel seat 2 and the movable straightening wheel seat 4 are provided with two rows of identical guide wheels 3 via a rotating shaft 21. One of the guide wheels 3 in the lower row is designated as a metering wheel 7. By adjusting the guide wheel 3 through the adjustment transmission assembly, cable feeding for cables of different diameters can be completed. The metering wheel 7, in conjunction with a length counter, achieves the effect of accurately feeding cables according to preset length data.

[0026] To facilitate adaptive adjustment of the distance between the upper and lower rows of guide rollers 3, the adjustment transmission assembly includes an adjustment frame 5 and an adjustment screw 6. An adjustment threaded cylinder 52 is mounted on the middle of the adjustment frame 5, and the adjustment screw 6 is mounted on the middle of the bracket 12, with its lower end threadedly connected to the adjustment threaded cylinder 51. An adjustment handle 61 is located at the top of the adjustment screw 6. Elastic adjustment arms 51 are mounted at both ends of the adjustment frame 5, with their bottom ends fixedly connected to the movable straightening wheel seat 4. Each elastic adjustment arm 51 includes a telescopic rod, around which compression springs are fitted. The cable is placed between the upper and lower rows of guide rollers 3; the adjustment is then rotated... The crank handle 61 rotates within the threaded adjusting cylinder 51, thereby driving the adjusting frame 5 to move downwards. The adjusting frame 5, through the elastic adjusting arm 51, drives the movable straightening wheel seat 4 to move downwards along the positioning rod 13, so that the guide wheel 3 on the movable straightening wheel seat 4, the guide wheel 3 on the fixed straightening wheel seat 2, and the measuring wheel 7 are clamped on the outer surface of the cable. Under the elastic potential energy of the compression spring of the elastic adjusting arm 51, the upper row of guide wheels 3 is kept in cooperation with the lower row of guide wheels 3 to clamp the outer surface of the cable, which allows cables of different diameters to move between the upper and lower rows of guide wheels 3, improving work efficiency and applicability.

[0027] When straightening cables in practice, for example, if the current cable diameter is smaller than the previous cable diameter, when the cable passes between the upper and lower guide rollers 3, the elastic potential energy of the compression spring of the elastic adjusting arm 51 can drive the movable straightening wheel seat 4 to move down, further pressing down the guide rollers 3 on the movable straightening wheel seat 4, thereby reducing the width of the wire pressing gap, which is suitable for measuring cables with smaller diameters.

[0028] For example, if the diameter of the current cable is larger than the diameter of the previous cable, under the elastic potential energy of the compression spring of the elastic adjusting arm 51, when the cable passes between the upper and lower guide wheels 3, the cable with a larger diameter can drive the movable straightening wheel seat 4 and the guide wheel 3 above it to move upward. At this time, the adjusting screw 6 can also be rotated to move the adjusting frame 5 upward, which in turn drives the guide wheel 3 on the movable straightening wheel seat 4 to move upward. At this time, the width of the cable feeding gap will increase, and the current cable can be pulled out smoothly.

[0029] To ensure the stability of the vertical displacement of the movable straightening wheel seat 4, a positioning rod 13 is provided on the fixed straightening wheel seat 2. The positioning rod 13 slides through the positioning hole 41, and the movable straightening wheel seat 4 moves vertically along the positioning rod 13 through the positioning hole 41.

[0030] The shaft 21 of the measuring wheel 7 extends out of the concave base 1 and connects to the mechanical counter 10. The mechanical counter 10 is mounted on the outer wall of the concave base 1 via a mounting bracket and is used to read the number of rotations of the measuring wheel 7.

[0031] To prevent the gear 8 from rotating in the opposite direction and affecting the cable length measurement, the shaft 21 of the measuring wheel 7 is fixedly mounted on the outer side of the concave base 1. A limiting structure 9 is installed on the outer wall of the concave base 1 to prevent the gear 8 from rotating in the opposite direction. The limiting structure 9 includes a limiting piece 91, one end of which is mounted on the outer wall of the concave base 1 via a pin, and the other end of which abuts against the lower end of the gear 8. A limiting stop 92 is provided above the limiting piece 91, fixed to the outer wall of the concave base 1 and fitting against the limiting piece 91, thus limiting the rotation of the gear 8. A support rod 93 is provided below the plate 91. The support rod 93 is fixed on the outer wall of the concave base 1. A spring 94 is provided on the support rod 93 to elastically support the limiting plate 91. When the gear 8 rotates, it squeezes the limiting plate 91, and the limiting plate 91 squeezes the spring 94, so that the gear 8 can rotate normally. When the cable moves in the opposite direction, the gear 8 rotates in the opposite direction. The limiting plate 91 is locked on the gear 8. The limiting stop rod 92 limits the limiting plate 91 to prevent it from rotating, thereby preventing the gear 8 from rotating in the opposite direction and preventing the wire wheel 3 and the metering wheel 7 from reversing.

[0032] When this utility model is used in one embodiment, such as Figure 2-4 As shown, three sets of identical guide wheels 3 are installed on the rotating shaft 21 of the fixed straightening wheel seat 2 and the movable straightening wheel seat 4, with the middle guide wheel 3 of the lower row designated as the measuring wheel 7. The cable is placed between the upper and lower rows of guide wheels 3. The rotating adjusting handle 61 rotates within the adjusting threaded cylinder 51, thereby causing the adjusting frame 5 to move downwards. The adjusting frame 5, through the elastic adjusting arm 51, causes the movable straightening wheel seat 4 to move downwards along the positioning rod 13. The elastic adjusting arm 51 keeps the guide wheels 3 on the movable straightening wheel seat 4 clamped to the outer surface of the cable along with the guide wheels 3 and measuring wheel 7 on the fixed straightening wheel seat 2. When the cable moves, it drives the conductor wheel 3 and the metering wheel 7 to rotate. The metering wheel 7 drives the gear 8 and the mechanical counter 10 to rotate. The mechanical counter 10 reads the number of rotations of the metering wheel 7 and then obtains the length of the cable based on the circumference of the metering wheel 7. When the gear 8 rotates, it presses the limiting plate 91, which in turn presses the spring 94, allowing the gear 8 to rotate normally. When the cable moves in the opposite direction, the gear 8 rotates in the opposite direction. The limiting plate 91 is locked onto the gear 8, and the limiting stop bar 92 limits the limiting plate 91 to prevent it from rotating, thereby preventing the gear 8 from rotating in the opposite direction and preventing the conductor wheel 3 and the metering wheel 7 from reversing.
