DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Referring to Figures 1-3 An embodiment provided by the utility model: a concrete sample sampler for supervision, including support plate 1, support plate 1 bottom fixedly connected with outer cylinder 2, outer cylinder 2 bottom fixedly connected with conical head 3, outer cylinder 2 left and right two ends are provided with first sampling port 4, the inner wall of outer cylinder 2 is provided with inner cylinder 5, and the left and right two ends of inner cylinder 5 are provided with second sampling port 6, and the top of inner cylinder 5 is fixedly connected with connecting frame 8, and the inner wall of support plate 1 left end is slidably connected with fixed block 9, and the top of fixed block 9 is fixedly connected with paddle 10, and fixed block 9 and the inner wall of support plate 1 are connected through first spring 11, and the top side of the left end of inner cylinder 5 is provided with first fixed groove 12, and the top side of the front end of inner cylinder 5 is provided with second fixed groove 13, and one end of first spring 11 is connected with fixed block 9, and the other end of first spring 11 is connected with the inner wall of support plate 1, and the inner wall of inner cylinder 5 is slidably connected with connecting rod 16, and the outer wall of connecting rod 16 is slidably connected on the inner wall of connecting frame 8, and the left and right two ends of support plate 1 are fixedly connected with handle 7;

[0026] Specifically, the operator holds handle 7, and outer cylinder 2 is inserted into the target concrete sample by conical head 3. Concrete mortar then flows into inner cylinder 5 through first sampling port 4 and second sampling port 6. Then, pull paddle 10 to move fixed block 9 to the left, and release its fixation on inner cylinder 5. At this time, rotate connecting frame 8 to make inner cylinder 5 rotate 90 degrees clockwise, so that second fixed groove 13 is aligned with fixed block 9. The elastic force of first spring 11 will push fixed block 9 to move to the right, reposition inner cylinder 5, and ensure that second sampling port 6 is located inside outer cylinder 2 to prevent mortar from spilling. Such design facilitates the transportation of samples, and when fixed block 9 releases inner cylinder 5, inner cylinder 5 can be easily taken out through connecting frame 8 for replacement.

[0027] Referring to Figure 1 and Figure 4, the baffle 14 fixedly connected to the bottom end of the connecting rod 16, the sealing gasket 15 fixedly connected to the outer wall of the baffle 14, the limiting plate 18 fixedly connected to the top end of the connecting rod 16, the second spring 19 connected between the bottom end of the limiting plate 18 and the top end of the inner cylinder 5, one end of the second spring 19 connected to the bottom end of the limiting plate 18, the other end of the second spring 19 connected to the top end of the inner cylinder 5, and the pull plate 17 fixedly connected to the top end of the connecting rod 16;

[0028] Specifically, when the sample in the inner cylinder 5 needs to be quickly extracted, the pull plate 17 is simply pulled upwards, which will cause the baffle 14 on the connecting rod 16 to move upwards, so that the sample can easily fall from the bottom end of the inner cylinder 5. After the sample is taken out, the elastic force of the second spring 19 will cause the limiting plate 18 to move upwards, thereby pushing the baffle 14 on the connecting rod 16 back to the original position.

[0029] Working principle: first, the staff holds the handle 7, inserts the outer cylinder 2 into the concrete to be sampled through the conical head 3, the concrete mortar can enter the inner cylinder 5 through the first sampling port 4 and the second sampling port 6, then the fixed block 9 is moved to the left by pulling the pull piece 10, thereby releasing the fixation of the inner cylinder 5 by the fixed block 9, at this time, the inner cylinder 5 is rotated clockwise by 90 degrees through the connecting frame 8, so that the second fixed groove 13 corresponds to the position of the fixed block 9, then the fixed block 9 is moved to the right by the elastic force of the first spring 11, thereby limiting the inner cylinder 5 again, so that the second sampling port 6 is located in the outer cylinder 2, preventing the concrete mortar from spilling, facilitating the transportation of the sample, and when the fixed block 9 releases the fixation of the inner cylinder 5, the inner cylinder 5 can be taken out through the connecting frame 8, facilitating the replacement of the inner cylinder 5, secondly, when the sample in the inner cylinder 5 needs to be quickly taken out, the pull plate 17 is pulled upwards, thereby causing the baffle 14 on the connecting rod 16 to move upwards, thereby facilitating the sample to fall out of the bottom end of the inner cylinder 5, and after the sample is taken out, the limiting plate 18 is moved upwards by the elastic force of the second spring 19, thereby causing the baffle 14 on the connecting rod 16 to reset.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application.
