DETAILED DESCRIPTION

[0021] The technical solutions in the utility model are further described below with reference to the drawings and examples.

[0022] In the description of the utility model, it is understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0023] In the exemplary embodiments, as Figures 1-5As shown, the present embodiment provides a concrete test block curing box, the curing box comprises a box body 1, and a pair or more pairs of supporting strips 2 are further arranged on the inner wall of the box body 1. A bracket structure capable of being placed between each pair of supporting strips 2 is further provided, the bracket structure comprises a pair of vertical plates 3, and a plurality of supporting rods 4 connected between the lower ends of the two vertical plates 3. The upper end of each vertical plate 3 is further fixedly connected with a supporting plate 5 on the side opposite to the vertical plate 3. The supporting plate 5 extends horizontally, and a mounting portion 6 is further fixedly arranged on the side wall of the supporting plate 5 close to the vertical plate 3. At least one pair of mounting shafts 7 is fixedly connected to the mounting portion 6. A roller 8 is rotatably connected to each mounting shaft 7, and the roller 8 has a portion located below the mounting portion 6. The two vertical plates 3 provide a mounting base for the supporting rods 4. The two ends of the supporting rods 4 and the vertical plates 3 can be fixedly connected, such as welding, threaded connection, etc. This makes the overall structure of the supporting rods 4 and the vertical plates 3 more stable. The supporting plate 5 arranged at the upper end of the vertical plate 3 provides a mounting base for the roller 8, and part of the roller 8 is located below the mounting portion 6 (at the same time, the two mounting portions 6 can be located above the corresponding supporting strips 2, or between the two supporting strips 2, to avoid interference caused by contact between them and the supporting strips 2. More specifically, the vertical plate 3 can be directly fixedly connected with the mounting portion 6. Similarly, the two vertical plates 3 are located between the two supporting strips 2 to avoid interference). The roller 8 can smoothly contact the supporting strips 2 below. This is a rolling contact during the process of pushing in or pulling out the bracket structure, making the process of pushing in or pulling out easier, and the friction is correspondingly smaller, so the damage is correspondingly smaller. This solves the problem of damage to the support structure in the curing box caused by the bracket and the concrete test block 13 during the process of putting in or taking out in the prior art. In a further scheme, a first perforation 9 is further arranged on the supporting plate 5, and a positioning rod 10 is arranged to pass through the first perforation 9. The positioning rod 10 is further fixedly connected with a horizontal rod 11, that is, the positioning rod 10 is arranged in a "7" shape as a whole, and can be supported on the supporting plate 5. Correspondingly, a second perforation is arranged on the supporting strip 2 for the positioning rod 10 to pass through. In this way, the bracket structure and the supporting strip 2 can be detachably locked by the "7" shaped supporting rod 4, so that the bracket structure will not accidentally fall due to rolling during the curing process. When it is necessary to pull out, the positioning rod 10 can be removed, which is very convenient.

[0024] As shown in Figure 2 , 3 and 5, in a further scheme, the two ends of the two vertical plates 3 are further fixedly connected with a blocking rod 12 located above all the supporting rods 4. The two blocking rods 12 can be fixedly connected with the supporting rods 4, which provides a limit for the concrete test block 13 on both sides to prevent the concrete test block 13 from accidentally falling.

[0025] As shown in Figure 2 , 4As shown, in a more detailed scheme, the rolling surface of the roller 8 is concave and provided with a ring groove 14, and the corresponding supporting strip 2 is convex and provided with a convex strip 15, and the convex strip 15 can be inserted into the ring groove 14, so that the cooperation between the convex strip 15 and the ring groove 14 provides alignment conditions for the supporting structure, and the insertion process is smoother, and more specifically, the cross section of the ring groove 14 and the cross section of the convex strip 15 are both arc-shaped, and the arc of the convex strip 15 is slightly smaller than the ring groove 14, so as to ensure smooth alignment.

[0026] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
