DETAILED DESCRIPTION

[0022] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Reference Figure 1-Figure 4 A vertically retractable distance measuring device comprises a multi-segment telescopic rod 1, wherein the multi-segment telescopic rod 1 is a retractable multi-segment design, each segment is locked by friction, and a support slide bar 2 can be lifted to a desired height by the multi-segment telescopic rod 1, a support slide bar 2 is arranged at the end of the multi-segment telescopic rod 1, two sets of sliding sleeves 3 are arranged on the outer sleeve of the support slide bar 2, and a measuring clamping part 4 is arranged on the surface of the two sets of sliding sleeves 3, and the measuring clamping part 4 comprises a clamping section 41 fixedly connected to the sliding sleeve 3, a guide section 42 formed at the end of the clamping section 41, and a through hole is opened at the bottom of the clamping section 41, and a laser rangefinder 5 is arranged in the through hole;

[0024] When measuring, the two measuring clamping parts 4 are lifted to the position to be measured through the cooperation of the multi-segment telescopic rod 1 and the supporting slide bar 2, and the two groups of guide segments 42 first contact the part to be measured, and continue to push the measuring clamping part 4 upward through the multi-segment telescopic rod 1 and the supporting slide bar 2, and the two groups of guide segments 42 drive the sliding sleeve 3 to slide and open laterally along the supporting slide bar 2. At the same time, the two groups of guide segments 42 respectively guide the two groups of clamping segments 41 to contact the structure to be measured, and the two groups of clamping segments 41 move laterally on the surface of the sliding sleeve 3 until the clamping segments 41 are clamped on both sides of the structure to be measured. The laser rangefinder 5 measures the distance from the other group of clamping segments 41 to the clamping segments 41 at the location where the laser rangefinder 5 is set, and the obtained measurement data is the structure data.

[0025] The clamping section 41 also includes a reinforcing sheet 43, which is formed on both sides of the bottom end of the clamping section 41, and the bottom end of the reinforcing sheet 43 is fixedly connected to the sliding sleeve 3. The reinforcing sheet 43 can strengthen the structural strength of the connection between the clamping section 41 and the sliding sleeve 3, thereby ensuring the connection stability. At the same time, the reinforcing sheet 43 cooperates with the sliding sleeve 3 to form a protective space for placing the laser rangefinder 5, thereby protecting the laser rangefinder 5 in the protective space, avoiding the laser rangefinder 5 from being completely exposed, and reducing the probability of damage caused by external collision.

[0026] The measuring clamping part 4 also includes a limit plate 44, which is formed on the surface of the clamping section 41. The limit plate 44 is located above the position where the laser rangefinder 5 is set in the clamping section 41. When the clamping section 41 is clamped to the edge of the part to be measured, the limit plate 44 can limit the maximum movable distance of the clamping section 41 relative to the part to be measured, thereby preventing the part to be measured from reaching the bottom of the clamping section 41 and affecting the normal measurement of the laser rangefinder 5.

[0027] An inner groove 6 is provided inside the supporting slide bar 2, and a measuring part reset device is arranged inside the inner groove 6. Both sets of sliding sleeves 3 are connected to the measuring part reset device, and the measuring part reset device comprises a connecting block 7 and a reset spring 8. The connecting block 7 is arranged at the middle position of the measuring clamping part 4. One ends of the two sets of reset springs 8 are respectively fixedly connected to the two sides of the connecting block 7, and the other ends of the two sets of reset springs 8 are respectively fixedly connected to the two sets of sliding sleeves 3. In the initial state, the distance between the two sets of sliding sleeves 3 and the measuring clamping part 4 on the sliding sleeves 3 is limited by the initial state of the reset spring 8. When the measuring clamping part 4 enters the measuring position, it will pull the reset spring 8 due to the back-to-back sliding, so that the reset spring 8 is deformed and accumulates force. When the measuring clamping part 4 is released from the measuring position after completing the measurement, the reset spring 8 returns to its initial shape, and the measuring clamping part 4 is reset under the pull of the reset spring 8 to facilitate the next measurement.

[0028] A data display screen 9 is provided at the lower end of the multi-segment telescopic rod 1. The input end of the data display screen 9 is connected to the output end of the laser rangefinder 5. In the working state, the data obtained by the laser rangefinder 5 is displayed in real time on the data display screen 9. The operator can read the data readings at the measuring point in real time through the data display screen 9 to ensure the accuracy of data acquisition.

[0029] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
