[0002] In actual production or engineering, in some special cases, it is necessary not only to measure the moving distance of the parts, but also to limit the range of movement of the parts. For example, in order to ensure the safety of emergency deployment of the rocker arm in the aircraft cabin, the moving distance of the rocker arm should be kept within the range required by the technical conditions. However, there is currently no reliable method or tool to measure and limit the length dimension to within the range required by the technical conditions.
[0003] Compared with the existing cylindrical long rod distance measurement devices in actual use, one of which uses a handheld laser rangefinder to measure the distance in the plane direction. Due to human factors, this measurement method may cause the light output point of the rangefinder and the target point to be not on the same horizontal line, thereby increasing the transmission distance of the laser and causing measurement errors.

DETAILED DESCRIPTION
[0020] The following is combined with Figure 1-Figure 4 This application is described in further detail.
[0021] Embodiment 1
[0022] Reference Figure 1-Figure 4A columnar long rod distance measuring device, comprising a fixing plate 1, characterized in that: an adjusting frame 2 is welded in the middle of the top of the fixing plate 1, a limit gear 3 is embedded in the bottom inner end of the adjusting frame 2, a driving gear 4 is embedded in the top of the limit gear 3 on the inner side of the adjusting frame 2, and a rangefinder 5 is fixed to the top of the driving gear 4 by bolts, in order to realize distance detection;
[0023] The outer side of the rangefinder 5 is sleeved with a shell 6, and the top of the fixing plate 1 is welded with a horizontal frame 7 at both ends of the outer side of the shell 6. A balance bar 8 is embedded at the bottom end of the top of the horizontal frame 7. A comparison frame 9 is mounted on the outer side of the balance bar 8. The bottom end of the comparison frame 9 is welded to the two ends of the outer side of the shell 6. The bottom end of the balance bar 8 is suspended on the inner side of the top of the comparison frame 9, and the top surface of the balance bar 8 is parallel to the top surface of the comparison frame 9. In order to achieve precise adjustment of the rangefinder, an angle fixing limiter 10 is installed on the outer side of one end of the adjustment frame 2, and the limit gear One end of the wheel 3 extends through and extends to the outside of the adjustment frame 2 and fits with one end of the angle fixing limiter 10. Three sockets 11 are welded at the bottom end of the fixed plate 1. A telescopic support rod 12 is embedded on the inner side of the socket 11. A telescopic limiter 13 is installed on the middle outer side of the telescopic support rod 12. A supporting base 14 is embedded at the bottom end of the telescopic support rod 12. Angle adjustment limiters 15 are installed on the outsides of the three sockets 11. The angle fixing limiter 10, the telescopic limiter 13 and the angle adjustment limiter 15 are all bolt limiters.
[0024] Working principle: First, the operator places the rangefinder at the designated position, and then adjusts the height of the rangefinder according to the height of the target to be detected. During this period, the operator loosens the three telescopic limiters 13, and then pulls out the telescopic support rod 12 according to the target height, and then tightens the telescopic limiter 13 again. Then, the operator needs to loosen the three angle limiters 15, and then adjust the angles of the three telescopic support rods 12, so as to achieve fine adjustment of the height of the rangefinder relative to the ground. After the adjustment is completed, the operator tightens the angle limiter 15 again, and then the height adjustment of the rangefinder can be completed;
[0025] After the device is fixed relative to the ground, the horizontal frames 7 welded on both sides of the top of the fixing plate 1 will support the balance bar 8 for balanced rotation. Since the weight of the outer sides of the two ends of the balance bar 8 is the same, if the top surface of the fixing plate 1 is skewed, the horizontal frame 7 will also be skewed, and the balance bar 8 embedded in the inner side of the horizontal frame 7 will be in a horizontal state due to gravity. At that time, the operator only needs to use the adjustment frame 2 as a support to rotate the active gear 4, and at the same time, the rangefinder 5 fixed by bolts on the top of the active gear 4 will also rotate. As the rangefinder 5 rotates, the housing 6 sleeved on the outside of the rangefinder 5 and the comparison frame 9 welded thereto will also rotate. Because the top surface of the balance bar 8 is parallel to the top surface of the comparison frame 9, the comparison frame 9 can be adjusted with the top surface of the balance bar 8 as a reference, thereby achieving the adjustment of the rangefinder 5. This design makes the adjustment of the distance measuring device more accurate and the measurement result more accurate.
[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
