[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] As attached Figure 1 -Appendix Figure 5 This utility model provides a technical solution: a portable ultrasonic rangefinder for engineering measurement, including a protective case 1 and a protective cover 6. The protective case 1 is equipped with a pop-out mechanism 4 and a limit assembly 5. The pop-out mechanism 4 includes a first slide plate 46, a second column 49, and a second slide plate 412. Multiple sets of first teeth 48 are fixedly connected to the side end of the first slide plate 46, and an arc-shaped block 45 is fixedly connected to the top of the first slide plate 46. A first sliding groove 44 is provided on the side end of the protective case 1. The side end of the first slide plate 46 and the side end of the arc-shaped block 45 are slidably connected inside the first sliding groove 44. A spring 47 is provided at the bottom of the first slide plate 46. A gear 410 is provided on the outer wall of the second column 49, meshing with multiple sets of first teeth 48. Multiple sets of second teeth 413 are provided on the side end of the second slide plate 412, meshing with multiple sets of second teeth 413. A third sliding groove 412 is provided inside the protective case 1. The side end of the second slide plate 412 and multiple sets of second teeth 413 are slidably connected to the inside of the third slide groove 411. The bottom of the second slide plate 412 is fixedly connected to the first connecting plate 414. The bottom of the first connecting plate 414 is fixedly connected to the second connecting plate 415. The bottom end of the second connecting plate 415 is fixedly connected to the third connecting plate 417. The inside of the protective box 1 is provided with a fifth slide groove 416. The side ends of the first connecting plate 414, the second connecting plate 415 and the third connecting plate 417 are slidably connected to the inside of the fifth slide groove 416. The top of the third connecting plate 417 is provided with multiple contact blocks 418. The side end of the protective box 1 is provided with two hinges 3. The side end of the protective box 1 is provided with a door 2 through the hinges 3. The inside of the protective box 1 is provided with an ultrasonic rangefinder 7. The side end of the door 2 is provided with a first column 41. The side end of the first column 41 is fixedly connected to a through column 42. The side end of the protective box 1 is provided with a slot 43.

[0026] The overall effect of Embodiment 1 is as follows: the relevant components can improve the convenience of taking out the traditional portable ultrasonic rangefinder for engineering measurement through mechanical transmission. By setting the arc block 45, it is easier to squeeze the arc block 45 when the door 2 drives the first column 41 and the through column 42 to rotate, which promotes the sliding of the first slide plate 46 inside the protective box 1. The function of setting the spring 47 is to make the first slide plate 46 reset with the reset of the door 2, which is convenient for popping out the ultrasonic rangefinder next time. This mechanical transmission method makes the ultrasonic rangefinder pop up inside the protective box when the door 2 is folded, which reduces the cumbersomeness of taking out the ultrasonic rangefinder.

[0027] Example 2, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the limiting component 5 includes a first slider 51, a second slide groove 52 is provided inside the protective box 1, the side end of the first slider 51 is slidably connected to the inside of the second slide groove 52, the two sides of the second slide plate 412 are fixedly connected to the second slider 53, and two fourth slide grooves 54 are provided inside the protective box 1, the side end of each second slider 53 is slidably connected to the inside of the fourth slide groove 54.

[0028] The effect achieved by the entire embodiment 2 is as follows: through the limiting component 5, the first slider 51 and the second slider 53 follow the first slide plate 46 and the second slide plate 412 to slide inside the second slide groove 52 and the fourth slide groove 54 respectively, thereby improving the stability of the first slide plate 46 and the second slide plate 412 sliding inside the protective box 1.

[0029] The working principle of the entire equipment is as follows: Installation and inspection phase: Before starting the test, ensure that all parts of the structure are in a stable state to prevent any part of the structure from malfunctioning after the work is completed.

[0030] Pop-up ultrasonic rangefinder stage: When the operator wants to pop the ultrasonic rangefinder out of the protective box 1, the operator opens the door 2. At this time, the door 2 drives the first column 41 and the through column 42 to rotate around the hinge 3. The door 2 continues to rotate, and the door 2 drives the through column 42 to press the arc block 45. At this time, the arc block 45 drives the first slide plate 46 to slide downward in the first slide groove 44. The spring 47 is compressed and deformed. At the same time, the first slider 51 slides downward in the second slide groove 52. Multiple sets of first teeth 48 mesh with the gear 410. At the same time, the gear 410 drives multiple sets of second teeth 413 to mesh with it. The second slide plate 412 and multiple sets of second teeth... 413 slides upward inside the third slide groove 411, while the second slider 53 follows the second slide plate 412 and slides upward inside the fourth slide groove 54. The second slide plate 412 drives the first connecting plate 414, the second connecting plate 415 and the third connecting plate 417 to slide upward inside the fifth slide groove 416. The third connecting plate 417 drives the contact block 418 to press the ultrasonic rangefinder upward, causing the ultrasonic rangefinder to pop up inside the protective sleeve plate 6, making it easy for the operator to pick up the ultrasonic rangefinder. When the ultrasonic rangefinder is put back into the protective box 1, the door 2 is rotated in the opposite direction. Due to the reaction force of the spring 47, the above operation is reversed, completing the placement of the ultrasonic rangefinder.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
