[0001] The utility model relates to the technical field of measuring tools, in particular to a cable width measuring tool. Background Art

[0002] Flex cables, also called flexible printed circuits (FPC), follow the industry specifications for flex cables, line order, line color, line number, etc., and are used for data transmission within active parts and active areas, such as the data cable connecting the computer's internal motherboard to the hard drive and optical drive, the data cable connecting the mobile phone motherboard to the display, and the data cable connecting devices are collectively referred to as flex cables. Since the flex cables themselves are relatively thin, it is difficult to measure their width.

[0003] At present, the main method for measuring the width of the cable is to use a vernier caliper. However, since the cable is easily deformed, it is difficult to control the force when measuring with a vernier caliper, which affects the accuracy of the test results. Based on this, in order to improve the accuracy and efficiency of the cable width measurement, it is necessary to improve the existing measurement tools. Utility Model Content

[0004] The utility model aims to solve the disadvantages in the prior art that the width of the cable is difficult to measure due to the thin connection of the cable itself, and proposes a cable width measuring tool.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A driving assembly is arranged inside the rod body, and the driving assembly is used to drive the positioning member to move linearly. A slideway is also provided at the upper end of the rod body, and at least part of the positioning member slides in the slideway.

[0008] Furthermore, the driving assembly includes a screw rod rotatably connected to the inside of the rod body, and a sliding seat is also slidably provided in the rod body, and the sliding seat is threadedly connected to the screw rod.

[0009] Furthermore, the positioning member is in a U-shaped structure, one end of which slides in the slideway and is fixedly connected to the slide seat. The outer surface of the positioning member also has a stop portion opposite to the outward expansion portion, and the stop portion is arranged on the side of the positioning member.

[0010] Furthermore, a partition is fixedly installed on the inner side of the rod body, and the screw rod passes through the partition and is rotatably connected.

[0011] Furthermore, a rectangular portion is fixed at the end of the screw rod, a rotating sleeve is sleeved on the outer side of the rectangular portion, and a spring is fixedly connected between the inner side of the rotating sleeve and the rectangular portion.

[0012] Furthermore, an outer expansion ring is fixed to the end of the rotating sleeve, and a plurality of teeth are circumferentially distributed on the end faces of the outer expansion ring and the partition, and the outer expansion ring and the partition are circumferentially locked by the teeth.

[0013] Furthermore, an auxiliary sleeve is fixed on the outer side of the shaft, and the thickness of the auxiliary sleeve is the same as that of the two side surfaces of the outward expansion portion.

[0014] The utility model proposes a cable width measuring tool, which has the beneficial effects of: the utility model adopts an adjustable positioning piece and an outer expansion part to form a width measuring space, and the width measurement is achieved by horizontally placing the cable to be measured in the measuring space. Due to the horizontal placement, the actual width of the cable can be observed intuitively, avoiding the measurement error problem caused by unstable force when using a vernier caliper, thereby greatly improving the convenience and applicability of measurement.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3An embodiment of the utility model discloses a cable width measuring tool, the measuring tool comprising a shaft 1 with a scale portion 13, one end of the shaft 1 having an outward expansion portion 11, and a positioning member 2 is slidably connected to the surface of the shaft 1, the side view of the large outward expansion portion 11 is an elliptical structure, the outward expansion portion 11 and the positioning member 2 form a measuring interval, and the cable to be measured is placed in the measuring interval to achieve width detection;

[0021] A driving assembly 3 is provided inside the shaft 1 , and the driving assembly 3 is used to drive the positioning member 2 to move linearly. A slideway 12 is also provided at the upper end of the shaft 1 , and at least part of the positioning member 2 slides in the slideway 12 .

[0022] In some embodiments, the driving assembly 3 in the utility model includes a screw 31 rotatably connected to the inside of the shaft 1, and a slide seat 32 is also slidably provided in the shaft 1, and the slide seat 32 is threadedly connected to the screw 31, that is, in this embodiment, the screw 31 is driven to rotate circumferentially to drive the slide seat 32 to move laterally inside the shaft 1. Furthermore, in this embodiment, the interior of the shaft 1 is a tubular structure.

[0023] On the basis of the above-mentioned embodiment, the positioning member 2 in this embodiment is in a U-shaped structure, one end of which slides in the slide 12 and is fixedly connected to the slide seat 32. A stop portion 21 opposite to the outward expansion portion 11 is also provided on the outer surface of the positioning member 2, and the stop portion 21 is arranged on the side of the positioning member 2.

[0024] During the specific test, first rotate the screw 31 according to the required width. When the screw 31 drives the slide 32 to move horizontally inside the rod body 1, the positioning member 2 moves synchronously with the slide 32. In this process, the inner side of the outer expansion portion 11 is used as the scale zero point. The width space to be measured is determined according to the positioning value of the stop portion 21 on the positioning member 2 and the scale portion 13. After the width adjustment is completed, stop driving the screw 31, and place the produced wire flat in the width space for comparison. If the actual width of the cable is greater than the set value, it is necessary to reduce the width space to complete the actual reading. If the actual width of the cable is less than the required value, observe the corresponding actual size to confirm whether the actual value meets the design requirements.

[0025] Furthermore, in this embodiment, a partition plate 14 is fixedly installed on the inner side of the shaft 1, and the screw rod 31 passes through the partition plate 14 and is rotatably connected.

[0026] In addition, in some embodiments, a rectangular portion 33 is fixed to the end of the screw rod 31 in the utility model, a rotating sleeve 34 is sleeved on the outer side of the rectangular portion 33 , and a spring 35 is fixedly connected between the inner side of the rotating sleeve 34 and the rectangular portion 33 .

[0027] On the basis of the above-mentioned embodiment, an outer expansion ring 36 is fixed to the end of the rotating sleeve 34 in this embodiment, and a plurality of teeth 37 are circumferentially distributed on the end faces of the outer expansion ring 36 and the partition 14. The outer expansion ring 36 and the partition 14 are circumferentially locked by the teeth 37. That is to say, in this embodiment, by adopting the design of a retractable rotating sleeve 34, in the initial state, the outer expansion ring 36 is pulled by the spring 35 to contact the partition 14, and the two are mutually locked by their respective teeth 37. The purpose of this design is to ensure that the rotating sleeve 34 does not rotate in the initial state, so as to ensure the position stability of the positioning member 2. When it is necessary to drive the screw 31 to rotate, the rotating sleeve 34 is first pulled outward to separate the outer expansion ring 36 from the partition 14, so that the rotating sleeve 34 can be easily rotated.

[0028] It should be noted that, in this embodiment, an auxiliary sleeve 15 is fixed to the outside of the shaft 1, and the auxiliary sleeve 15 has the same thickness as the two side surfaces of the expansion portion 11. The purpose of providing the auxiliary sleeve 15 is to support the shaft 1, that is, to support the two ends of the shaft 1 through the expansion portion 11 and the auxiliary sleeve 15, so that the tool can be placed on the desktop in a stable manner to optimize the convenience of measurement.

[0029] In summary, the utility model adopts an adjustable positioning member 2 and the expansion part 11 to form a width measurement space, and the width measurement is achieved by placing the cable to be measured horizontally in the measurement space. Due to the horizontal placement, the actual width of the cable can be observed intuitively, avoiding the measurement error problem caused by unstable force using a vernier caliper, thereby greatly improving the convenience and applicability of the measurement. Secondly, the two ends of the shaft 1 in the utility model are supported by the expansion part 11 and the auxiliary sleeve 15, which can realize the horizontal placement of the tool to optimize the reliability during the width measurement process.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
