Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] like Figures 1 to 6 As shown, a sampling device for construction engineering supervision includes an outer cylinder 1, an inner cylinder 2, a sampling cylinder 3, and a limiting component 4. The inner cylinder 2 is slidably disposed inside the outer cylinder 1, and its lower end is threadedly connected to the sampling cylinder 3. A through hole 11 and a blind hole 12 are provided on the side wall of the outer cylinder 1, with the through hole 11 located above the blind hole 12. A slot 21 corresponding to the through hole is provided on the side wall of the inner cylinder 2. The limiting component 4 includes a foot pedal 41 and a limiting member 42. The foot pedal 41 is slidably disposed outside the outer cylinder 1, and... An opening 411 is provided on it, and a limiting member 42 is provided in the opening 411. When the foot pedal 41 slides to the top of the outer cylinder 1, the limiting member 42 passes through the through hole 11 and is locked in the slot 21. When the foot pedal 41 slides to the bottom of the outer cylinder 1, the limiting member 42 is locked in the blind hole 12. Specifically, two openings 411 are symmetrically arranged on the left and right sides of the foot pedal 41, so that the limiting member 42 in the opening 411 can be locked in the through hole 11 or the blind hole 12 from both sides, thereby improving the stability of the device.

[0032] This utility model is small in size and easy to carry, making it suitable for individual operation in environments with limited space. At the same time, it adopts a slidable limiting component 4 on the outer cylinder 1. Utilizing its sliding characteristics, it can slide to the upper and lower positions of the outer cylinder 1 and cooperate with the through hole 11 or blind hole 12. This allows it to act as a limiting component for the inner cylinder 2 or as a foot pedal to assist in sampling, which helps prevent the inner cylinder from slipping during the process of picking up the device and improves the convenience of the device.

[0033] In this embodiment, please refer to Figure 2 and Figure 3 ,as well as Figure 5 and Figure 6The limiting component 42 includes a retaining shaft 421, a spring 422, and a washer 423. A receiving cavity 412 is provided inside the foot pedal 41 and located inside the opening 411. The retaining shaft 421 slides in the opening 411 and passes through the receiving cavity 412. The spring 422 is sleeved on the retaining shaft 421 inside the receiving cavity 412. One end of the spring 422 is connected to the inner wall of the receiving cavity 412, and the other end is connected to the washer 423. The washer 423 is fixedly installed on the retaining shaft 421. When the foot pedal 41 slides to the top of the outer cylinder 1, the retaining shaft 421 passes through the through hole 11 and is locked in the retaining groove 21. When the foot pedal 41 slides to the bottom of the outer cylinder 1, the retaining shaft 421 is locked in the blind hole 12.

[0034] In practical use, the foot pedal 41 can be set in different positions by pulling the locking shaft 421 and inserting it into the through hole 11 or the blind hole 12. That is, when it is necessary to transfer soil for sampling, the foot pedal 41 is slid to the blind hole 12 below the outer cylinder 1 and inserted into it by using the locking shaft 421. At this time, the foot pedal 41 is stepped on and the inner cylinder 2 is pressed down repeatedly to collect soil using the sampling cylinder 3. When the soil collection operation is stopped and the inner cylinder 2 is fixed, the foot pedal 41 is slid to the through hole 11 above the outer cylinder 1 and the locking shaft 421 is inserted into the locking groove 21 through the through hole 11.

[0035] The setting of the limiting member 42 makes it convenient to insert the foot pedal 41 into the through hole 11 or blind hole 12 of the outer cylinder 1 to limit the sliding of the inner cylinder 2 or to act as a foot pedal to assist sampling. It is convenient, quick and improves the flexibility of the device, and is worth promoting and applying.

[0036] Specifically, the limiting component 42 also includes an end piece 424 and a guide post 425. The end of the retaining shaft 421 located in the opening 411 is provided with an end piece 424, and guide posts 425 are provided on both sides of the retaining shaft 421. The guide posts 425 are slidably connected to the end piece 424. The end piece 424 is provided to facilitate manual stretching of the retaining shaft 421. The guide posts 425 facilitate guiding the retaining shaft 421.

[0037] In this embodiment, please refer to Figure 1 and Figure 4 Multiple sampling holes 31 are spaced apart on the side wall of the sampling cylinder 3. The sampling holes 31 are set to facilitate manual stepping on the foot pedal 41 and reciprocating pressing down on the inner cylinder 2. When soil is taken using the sampling cylinder 3, the soil sample enters the sampling cylinder 3. Then, the sampling cylinder 3 is removed by using the threaded connection between the sampling cylinder 3 and the inner cylinder 2, so that the soil sample can be collected in a concentrated manner.

[0038] In addition, a handle 5 is provided at the end of the inner cylinder 2 away from the sampling cylinder 3; the handle 5 facilitates manual pressing of the inner cylinder 2 to complete the soil sampling operation; the foot pedal 41 is provided with anti-slip texture 6; during the soil sampling process, the operator steps on the foot pedal 41, and the anti-slip texture 6 plays a role in preventing the foot from slipping.

[0039] The working principle of this utility model:

[0040] This utility model provides a sampling device for construction engineering supervision. In specific use, when soil sampling is required, the foot pedal 41 is slid onto the blind hole 12 below the outer cylinder 1 and inserted into it using the retaining shaft 421. At this time, the inner cylinder 2 is in a free sliding state. The user can step on the foot pedal 41 and press down the inner cylinder 2 repeatedly to collect soil using the sampling cylinder 3. When the soil sampling operation is stopped and the inner cylinder 2 is fixed, the foot pedal 41 is slid onto the through hole 11 above the outer cylinder 1 and inserted into the retaining groove 21 using the retaining shaft 421. The entire device can then be extracted to the next soil sampling operation, improving the flexibility of the device.
