[0023] See also Figure 1-4 The utility model provides a technical solution: a portable maintenance box, comprising a box body 1, universal wheels 2 are symmetrically installed at the four corners of the bottom of the box body 1, a control panel 3 is installed on one side of the box body 1, wherein a maintenance groove 4 is opened inside the box body 1 near the control panel 3, an inner liner 5 is installed on the inner wall of the maintenance groove 4, and a box cover 6 is rotatably connected to the side of the box body 1 near the maintenance groove 4; sliding frames 7 are equidistantly slidably arranged inside the inner liner 5, a placement plate 12 is arranged on the top of the sliding frame 7, and clamping frames 13 are symmetrically arranged on both sides of the top of the placement plate 12, and the clamping frames 13 are moved closer to or away from each other through an automatic clamping mechanism. By adopting the above-mentioned curing box, when the concrete specimen is placed in the curing box, the sliding frame 7 is pulled out of the interior of the curing groove 4, and then the concrete specimen is placed on the placement plate 12. The clamping frames 13 are brought close to each other by the automatic clamping mechanism to clamp the concrete specimen, and then the sliding frame 7 is sent back to the interior of the curing groove 4. When the curing box is moved by the universal wheel 2, the concrete specimen can be limited by the clamping structure to avoid shaking of the concrete specimen inside the curing box when the curing box is carried.

[0024] Furthermore, the entire maintenance box can be conveniently moved through the corresponding universal wheels 2, thereby increasing its flexibility and convenience in use and reducing the difficulty of the operator during the movement.

[0025] See also Figures 1 to 4The middle part of the sliding frame 7 is in the shape of a grid, and a bracket 8 is fixed to the inner wall of the inner tank 5 corresponding to the sliding frame 7. The bracket 8 is provided with a sliding groove 9 on the side close to the sliding frame 7, and a sliding block 10 is fixed to the side close to the sliding groove 9 of the sliding frame 7. A handle 11 is fixedly connected to the middle part of the opening side of the sliding frame 7 close to the curing groove 4. When it is necessary to take and place the concrete specimen, the sliding frame 7 is pulled by the handle 11. The sliding frame 7 can move out of or enter the interior of the curing groove 4 through the sliding structure formed by the sliding block 10 and the sliding groove 9. By taking and placing the concrete specimen on the outside of the curing groove 4, the box body 1 is avoided to cause obstruction, so as to take and place the concrete specimen, and after the sliding frame 7 enters the curing groove 4, the box cover 6 is closed, and the box cover 6 is pressed against the handle 11 to fix the position of the sliding frame 7.

[0026] Furthermore, by adopting the grid-shaped sliding frame 7, it is ensured that during the subsequent curing process, the bottom of the concrete specimen can also be normally cured, thereby ensuring the curing quality and effect.

[0027] See also Figures 1 to 4 The clamping frame 13 is V-shaped, and the automatic clamping mechanism includes a slide groove 14. The top of the placement plate 12 near the two sides of the clamping frame 13 is symmetrically provided with a slide groove 14. The bottom of the clamping frame 13 corresponding to the slide groove 14 is fixed with a slider 15, and the bottom of the slider 15 is rotatably connected with a transmission rod 16, and the end of the transmission rod 16 away from the slider 15 is rotatably connected to the top of the sliding frame 7. The four corners of the placement plate 12 are symmetrically penetrated with a guide groove 17, and the top of the sliding frame 7 corresponding to the guide groove 17 is fixed with a guide rod 18, and the guide rod 18 between the sliding frame 7 and the placement plate 12 is sleeved with a reset spring 19. When the concrete specimen is placed on the placement plate 12, the placement plate 12 The concrete specimen is supported by the clamping frames 13 on both sides, and the four corners of the concrete specimen can be supported at the same time by the V-shaped clamping frames 13, so that the concrete specimen can be limited in each sliding direction to avoid shaking of the concrete specimen when the curing box is moved. When the concrete specimen needs to be removed, the concrete specimen is lifted up, and the reset spring 19 drives the clamping frame 13 to reset, so that the concrete specimen can be removed. The automatic clamping mechanism is set so that the concrete specimen can be automatically clamped and fixed when it is placed, and the concrete specimen can be removed conveniently.

[0028] Furthermore, a control panel 3 is provided on the front side of the box body 1 and on the side of the curing tank 4. The control panel 3 can be used to control the entire curing box during the subsequent curing process to facilitate the curing.

[0029] Working process and principle of this utility model:

[0030] With the portable curing box of the utility model, when the concrete specimen is placed in the curing box, the sliding frame 7 is pulled out of the curing tank 4, and then the concrete specimen is placed on the placement plate 12. The clamping frames 13 are brought close to each other by the automatic clamping mechanism, and the concrete specimen is clamped. Then, the sliding frame 7 is sent back to the curing tank 4. When the curing box is moved by the universal wheel 2, the concrete specimen can be limited by the clamping structure, so as to avoid the concrete specimen from shaking inside the curing box when the curing box is carried.

[0031] When it is necessary to take or place the concrete specimen, the sliding frame 7 is pulled by the handle 11. The sliding frame 7 can move out of or into the interior of the curing groove 4 through the sliding structure formed by the sliding block 10 and the sliding groove 9. The concrete specimen is taken and placed outside the curing groove 4 to avoid obstruction caused by the box body 1, so that the concrete specimen can be taken and placed. After the sliding frame 7 enters the curing groove 4, the box cover 6 is closed, and the box cover 6 is pressed against the handle 11 to fix the position of the sliding frame 7. When the concrete specimen is placed on the placement plate 12, the placement plate 12 is moved downward by gravity to overcome the elastic force of the return spring 19, so that the concrete specimen can be placed on the curing groove 4. The transmission rod 16 drives the clamping frame 13 to move toward the concrete specimen, and the clamping frames 13 on both sides abut the concrete specimen. The V-shaped clamping frame 13 can abut the four corners of the concrete specimen at the same time, so that the sliding directions of the concrete specimen can be limited to avoid the shaking of the concrete specimen when the curing box is moved. When the concrete specimen needs to be removed, the concrete specimen is pulled upward, and the reset spring 19 drives the clamping frame 13 to reset, so that the concrete specimen can be removed. The automatic clamping mechanism is set up so that the concrete specimen can be automatically clamped and fixed when it is placed, and the concrete specimen can be removed conveniently.
