[0032] Refer to Figures 1 to 4 , which shows a schematic structural diagram of a cable size measuring device in an embodiment of this application. The cable size measuring device includes a measuring assembly 100 and a marking assembly 200. The measuring assembly 100 includes a fixing member 110, a measuring tool 120 and a calibration member 130. The fixing member 110 is provided with a through hole 110A. The measuring tool 120 is connected to the fixing member 110. The fixing member 110 is used to movably pass the cable 10 to be measured through the through hole 110A. The calibration member 130 is used to be installed at the measurement starting end of the cable 10 to be measured. The measuring tool 120 is used to measure the length of the cable 10 to be measured between the fixing member 110 and the calibration member 130. The marking assembly 200 is movably installed on the fixing member 110, and the marking assembly 200 is used to mark the cable 10 to be measured.

[0033] In an exemplary embodiment, the fixing member 110 is disc-shaped, the through hole 110A is disposed on the central axis of the fixing member, and the measuring tool 120 and the marking assembly 200 are installed on the same side of the fixing member 110.

[0034] In an exemplary embodiment, the measuring tool 120 is a laser rangefinder. The length to the calibration member 130 is measured by the laser rangefinder. The laser rangefinder has the advantages of high measurement accuracy and easy operation and use. In other embodiments, the measuring tool 120 can also be a tape measure, and the size is measured by manually pulling the tape measure.

[0035] In the cable size measuring device according to the embodiment of the present application, a through hole 110A is provided in the fixing member 110, and the cable 10 to be measured is passed through the through hole 110A, so that the fixing member 110 can be translated on the cable 10 to be measured. The fixing member 110 is connected with a measuring tool 120, and a calibration member 130 is installed at the starting end of the measurement of the cable 10 to be measured, so that the measuring tool 120 can measure the length dimension between the calibration member 130 and the measuring tool 120. When the measuring tool 120 determines that the fixing member 110 is at the required size, the fixing member 110 is kept stationary, and then the cable 10 to be measured is marked at this position by operating the marking assembly 200, thus facilitating subsequent cutting work.

[0036] In the cable size measuring device according to the embodiment of the present application, by integrally installing the measuring tool 120 and the marking assembly 200 on the fixing member 110, it is convenient to store and preserve the whole device. The calibration member 130 can assist the measuring tool 120 to perform accurate measurement, and maintain the position of the fixing member 110 on the cable 10 to be measured after measurement, thereby limiting the movement of the marking assembly 200 in the length direction of the cable 10 to be measured, so that the marking assembly 200 can be operated to accurately mark the cable 10 to be measured, having the advantages of high measurement and marking accuracy and convenient operation.

[0037] In some embodiments, as Figures 1 to 2 shown, the marking assembly 200 includes a rotating disk 210, a mounting member 220 and a marking tool 230. The rotating disk 210 is rotatably connected to the fixing member 110, the mounting member 220 is connected to the rotating disk 210, the marking tool 230 is movably installed on the mounting member 220, and the marking tool 230 is arranged along the radial direction of the rotating disk 210.

[0038] In this embodiment, by providing the rotating disk 210 on the fixing member 110, and then connecting the marking tool 230 to the rotating disk 210 through the mounting member 220, the marking tool 230 is rotatably arranged around the through hole 110A. Therefore, the marking tool 230 can be operated to mark around the circumference of the cable 10 to be measured, and the axial movement of the marking tool 230 is limited, avoiding the deviation of the marking position caused by the offset of the marking tool 230 during marking, thus affecting the size of the cable.

[0039] In an alternative embodiment, as Figure 2 shown, the distance between the measurement starting point of the measuring tool 120 and the calibration member 130 is equal to the distance between the marking point of the marking tool 230 and the calibration member 130. In order to ensure that the marking position on the cable 10 to be measured is more accurate, the length from the measurement starting point of the measuring tool 120 to the calibration member 130 is made consistent with the length from the marking point of the marking tool 230 to the calibration member 130, so that the measured length and the marked length are consistent, thereby improving the accuracy between measurement and marking.

[0040] In an exemplary embodiment, as Figure 2 shown, the marking tool 230 is a paintbrush. The tip of the paintbrush is set towards the center of the through hole 110A. When marking, the tip of the paintbrush touches the outer side surface of the cable 10 to be measured. Rotating the paintbrush can draw a line mark on the cable 10 to be measured. In another embodiment, the marking tool 230 is a scriber. The scriber is set towards the center of the through hole 110A. When marking, the tip of the scriber abuts against the outer side surface of the cable 10 to be measured. Rotating the scriber can scribe a line mark on the outer skin of the cable 10 to be measured. In other embodiments, the marking tool 230 can also be a laser etcher. By setting the laser etcher towards the center of the through hole 110A, the outer side surface of the cable 10 to be measured can be etched and marked by using the laser etcher during marking, which has the advantages of simplicity and convenience.

[0041] In an alternative embodiment, as Figure 1 and Figure 2 shown, when the marking tool 230 is a paintbrush or a scriber, in order to fix the marking tool 230 to the mounting member 220, the mounting member 220 is provided with a mounting hole. The axial direction of the mounting hole is arranged along the radial direction of the through hole 110A, and the mounting hole faces... The marking tool 230 is movably arranged in the mounting hole. The mounting member 220 further includes an elastic member and a third fastener. The elastic member is installed at the bottom of the mounting hole, and the third fastener is arranged on the mounting member 220. The third fastener is used to fasten or loosen the marking tool 230. By inserting the marking tool 230 into the mounting hole and then fastening it with the third fastener, when the marking position is determined, first loosen the third fastener, and the elastic member spreads the marking tool 230 outwards, so that the marking point of the marking tool 230 falls on the outer side wall of the cable 10 to be measured. Then fasten the third fastener, and finally rotate the entire marking assembly 200, thereby completing the marking of the cable 10 to be measured, which has the advantage of convenient operation.

[0042] In an alternative embodiment, the mounting member 220 is provided with a through hole, and the through hole communicates with the mounting hole. The third fastener and the hole wall of the through hole are connected by a thread pair. Specifically, the third fastener is a threaded knob. By arranging the third fastener in the through hole with threads and rotating the third fastener, it can be adjusted whether the third fastener abuts against the marking tool 230 in the mounting hole, so as to fasten or loosen the marking tool 230 by adjusting the third fastener, which has the advantages of simple structure and convenient operation.

[0043] In an alternative embodiment, as Figures 1 to 4As shown, the fixing member 110 is provided with a boss 111. The boss 111 is arranged around the through hole 110A. A first mounting groove 111A is provided in the circumferential direction of the boss 111. The rotating disk 210 is movably arranged in the first mounting groove 111A. The fixing member 110 further includes a first fastener. The first fastener is mounted on the boss 111 and is used to fasten or loosen the rotating disk 210. By providing the boss 111 with the first mounting groove 111A on one side of the fixing member 110, the rotating disk 210 is rotatably arranged in the first mounting groove 111A, that is, the marking assembly 200 can be rotatably arranged around the circumferential direction of the through hole 110A, so that the marking assembly 200 marks around the circumferential direction of the cable under test 10. When the position of the fixing member 110 on the cable under test 10 is limited, the axial position of the marking assembly 200 on the cable under test 10 is also limited, so that the marking assembly 200 will not shift when rotating for marking, improving the accuracy of marking.

[0044] Furthermore, the rotating disk 210 is fastened or loosened by the first fastener. The marking assembly 200 is fastened before marking and loosened when marking is required. Specifically, the first fastener is a threaded knob. By providing a threaded hole in the boss 111, the threaded knob can be movably abutted against the rotating disk 210, so as to fasten or loosen the marking assembly 200.

[0045] In an alternative embodiment, as Figure 1 and Figure 4 shown, the measuring assembly 100 includes a plurality of telescopic sliders 150 and a second fastener. The fixing member 110 is provided with a plurality of second sliding grooves. The second sliding grooves are arranged along the radial direction of the through hole 110A. The telescopic sliders 150 are arranged in one-to-one correspondence with the second sliding grooves, and the telescopic sliders 150 are movably clamped in the second sliding grooves. The second fastener is movably arranged on the fixing member 110 and is used to fasten or loosen the telescopic sliders 150. Specifically, the second sliding grooves are arranged on the hole wall of the through hole 110A. In order to fix the fixing member 110 after determining the measurement size, the second sliding grooves are provided on the fixing member 110, and the telescopic sliders 150 are slidably arranged in the second sliding grooves. After adjusting to the position of the fixing member 110, loosen the second fastener, adjust the telescopic slider 150 to abut against the cable under test 10, and then fasten the telescopic slider 150 by the second fastener, so as to fix the relative position of the fixing member 110 and the cable under test 10.

[0046] In an exemplary embodiment, the second fastener is a threaded knob. By providing a threaded hole in the fixing member 110, the threaded knob can be movably abutted against the telescopic slider 150, so as to fasten or loosen the telescopic slider 150.

[0047] In an exemplary embodiment, as Figure 4As shown, a plurality of second sliding grooves and a plurality of telescopic sliders 150 are arranged at equal intervals in the circumferential direction around the through hole 110A, so that the force exerted by the telescopic sliders 150 on the cable under test 10 is more balanced, improving the fastening stability of the fixing member 110 and the convenience of operation.

[0048] In another embodiment, the measuring assembly 100 further includes a plurality of telescopic sliders 150 and elastic members. The fixing member 110 is provided with a plurality of second sliding grooves which are arranged along the radial direction of the through hole 110A. The telescopic sliders 150 are arranged in one-to-one correspondence with the second sliding grooves, and the telescopic sliders 150 are movably arranged in the second sliding grooves. One end of the elastic member is connected to the fixing member 110, and the other end of the elastic member is connected to the telescopic slider 150. The telescopic slider 150 of this embodiment can automatically adjust the telescopic slider 150 to abut against the cable under test 10 through the elastic member, having the advantage of convenient use.

[0049] In an alternative embodiment, as Figure 1 and Figure 3 shown, the calibration member 130 includes a calibration baffle 131 and a connection clip 132. The connection clip 132 is installed on the calibration baffle 131, and the connection clip 132 is used for clamping the starting end of the cable under test 10. The calibration baffle 131 is arranged perpendicular to the axial direction of the cable under test 10, and the measuring direction of the measuring tool 120 is perpendicular to the calibration baffle 131. Specifically, the starting end of the cable under test 10 can be the end of the cable under test 10 or the middle part of the cable under test 10. The calibration member 130 of the embodiment of the present application is used to assist the measuring tool 120 to measure the starting measurement point of the cable under test 10. Since the measuring tool 120 measures along the axial direction of the cable under test 10, the calibration baffle 131 needs to be arranged perpendicular to the axial direction of the cable under test 10. The calibration baffle 131 can be fixed on the cable under test 10 through the connection clip 132, so as to facilitate the measuring tool 120 to measure the distance from the calibration baffle 131, so as to obtain the measurement size of the cable under test 10 and improve the measurement accuracy.

[0050] In an alternative embodiment, as Figures 1 to 4 shown, the measuring assembly 100 further includes a fixed seat 140. The fixed seat 140 is connected to the rotating disk 210. The fixed seat 140 is provided with a second installation groove 140A, and the measuring tool 120 is detachably installed in the second installation groove 140A. By providing the fixed seat 140 to install the measuring tool 120, it is ensured that the relative position between the installation position of the measuring tool 120 and the fixing member 110 is fixed, so that the measuring tool 120 can be disassembled and assembled without debugging, which is convenient to use.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0052] The above-described embodiments only express several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
