Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-Figure 2 A modular meter counter includes: a meter box rotating cover 1, a meter box lower cover 2, a measuring mechanism and a main shaft 3. The end of the meter box lower cover 2 is provided in the opening of the meter box rotating cover 1, the measuring mechanism is connected to the meter box lower cover 2, the measuring mechanism is connected to the main shaft 3, and the main shaft 3 is connected to the meter box rotating cover 1.

[0023] The principles and beneficial effects of the above scheme are:

[0024] When measuring the wire, first fix the lower cover 2 of the meter box, then overlap the wire on the side wall of the rotating cover 1 of the meter box, pull the wire, and under the action of the main shaft 3, the wire drives the rotating cover 1 of the meter box to rotate. During the rotation, the measuring mechanism records the length of the pickles. By setting the rotating cover 1 of the meter box, the lower cover 2 of the meter box, the measuring mechanism and the main shaft 3 to work, the structure of the device is simple, and it is easy to move the device to any mechanism and measure the length of the wire, and it is highly versatile.

[0025] Example 2: Reference Figure 1-Figure 2 The main shaft 3 is provided with a ball bearing 4, and the ball bearing 4 is connected to the inner wall of the lower cover 2 of the meter box through a connecting mechanism.

[0026] The principles and beneficial effects of the above scheme are:

[0027] The inner wall of the lower cover 2 of the meter box is connected to the ball bearing 4 through a connecting mechanism. The ball bearing 4 is mounted on the main shaft 3. Therefore, the device provides a guiding mechanism for the rotating main shaft 3 during rotation, while increasing the strength of the main shaft 3 and preventing the main shaft 3 from deflecting during operation.

[0028] Example 3: Reference Figure 1-Figure 2 The connecting mechanism includes: a bearing fixing ring 5 and a bearing fixing sleeve 6, the end of the ball bearing 4 is connected to the end of the bearing fixing ring 5, the side wall of the bearing fixing ring 5 is connected to the inner wall of the bearing fixing sleeve 6, and the side wall of the bearing fixing sleeve 6 is plugged into the inner wall of the lower cover 2 of the meter box.

[0029] The principles and beneficial effects of the above scheme are:

[0030] The bearing fixing ring 5 is used to fix the ball bearing 4 on the bearing fixing sleeve 6, and the bearing fixing sleeve 6 is plugged into the inner wall of the meter box lower cover 2, which reduces the difficulty of installing and disassembling parts.

[0031] Example 4: Reference Figure 1-Figure 2 The top of the bearing fixing sleeve 6 is connected with a flange, and the flange is connected to the lower cover 2 of the meter box by bolts.

[0032] The principles and beneficial effects of the above scheme are:

[0033] The top end of the bearing fixing sleeve 6 is mounted on the meter box lower cover 2 through a flange and bolts, which improves the stability of the mechanism after installation and further enhances the stability of the ball bearing 4.

[0034] Example 5: Reference Figure 1-Figure 2 The side wall of the lower cover 2 of the meter box is covered with a star-shaped sealing ring 7, which is rotated and sealed with the inner wall of the rotating cover 1 of the meter box.

[0035] The principles and beneficial effects of the above scheme are:

[0036] The provision of the star-shaped sealing ring 7 can improve the sealing effect between the meter box lower cover 2 and the meter box rotating cover 1, preventing external debris from entering the interior of the device.

[0037] Example 6: Reference Figure 1-Figure 2 The inner wall of the meter box rotating cover 1 is connected to the top of the main shaft 3 through a damper 8.

[0038] The principles and beneficial effects of the above scheme are:

[0039] At the moment when the meter box rotating cover 1 starts to rotate or stops rotating, the damper 8 can provide sufficient buffer for the rotation or stopping of the main shaft 3, preventing wear between the main shaft 3 and the ball bearing 4, and at the same time avoiding damage to the measuring mechanism.

[0040] Example 7: Reference Figure 1-Figure 2 The measuring mechanism includes: a conductive slip ring 9, the bottom end of the conductive slip ring 9 is installed in the lower cover 2 of the meter box, and the top end of the conductive slip ring 9 is connected to the bottom end of the main shaft 3.

[0041] The principles and beneficial effects of the above scheme are:

[0042] The conductive slip ring 9 can not only serve as a power supply component, but also limit the main shaft 3 inside the device, and can also assist in rotating the main shaft 3, further improving the stability of the main shaft 3.

[0043] Example 8: Reference Figure 1-Figure 2 The main shaft 3 is provided with a circular ring 10, and the side wall of the circular ring 10 is provided with a Great Wall tooth.

[0044] The principles and beneficial effects of the above scheme are:

[0045] When measuring the length of the wire, the main shaft 3 rotates to drive the ring 10 to rotate, and the Great Wall teeth on the ring 10 rotate synchronously.

[0046] Example 9: Reference Figure 1-Figure 2 A PCB board 11 is connected to the lower cover 2 of the meter box. A mounting hole is opened in the middle of the PCB board 11. The conductive slip ring 9 is located in the mounting hole. A photoelectric sensor is installed on one side of the PCB board 11, and the end of the photoelectric sensor is set toward the Great Wall tooth.

[0047] The principles and beneficial effects of the above scheme are:

[0048] When measuring the length of the wire, the photoelectric sensor on the PCB board 11 counts the Great Wall teeth.

[0049] Example 10: Reference Figure 1-Figure 2 The other side of the PCB board 11 is electrically connected to the conductive slip ring 9 through a wire. An aviation head fixing seat 12 is installed in the lower cover 2 of the meter box. The conductive slip ring 9 is electrically connected to the end of the aviation head fixing seat 12 through a second wire. The other end of the aviation head fixing seat 12 is extended to the outside of the lower cover 2 of the meter box.

[0050] The principles and beneficial effects of the above scheme are:

[0051] The counting output signal is input to the wire through the PCB board 11, input to the conductive slip ring 9 through the wire, input to the aviation head fixing seat 12 through the conductive slip ring 9 and the second wire, and then the aviation head fixing seat 12 outputs the signal, which greatly reduces the complexity of the device.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
