Detailed Description
The technical solution of the present invention is further specifically described below by way of specific embodiments and with reference to the accompanying drawings.
As shown in figures 1-3, the portable concrete slump tester of the utility model mainly detachably connects the concrete slump measuring cylinder (5) to the base (6), so as to conveniently load concrete into the concrete slump measuring cylinder (5), and in addition, after the test is completed, other measuring parts (such as a tamping bar (1), a measuring scale (2) and a shovel (3)) can be placed in the concrete slump measuring cylinder (5) so as to be convenient to carry. Specifically, two symmetrical movable pressing plates (7) are arranged on the base (6), and during manufacturing, the two movable pressing plates (7) capable of rotating left and right are symmetrically arranged on the upper plane of the base (6) in the left-right direction. Correspondingly, the bottom of the outer side wall of the concrete slump measuring cylinder (5) is provided with two symmetrical measuring cylinder fixing clamping plates (8), and in a specific embodiment, the two measuring cylinder fixing clamping plates (8) are welded below the concrete slump measuring cylinder (5) in a bilateral symmetry mode. After the concrete slump measuring cylinder (5) is arranged on the base (6), the movable pressing plate (7) presses and tightly clamps the measuring cylinder fixing clamping plate (8), so that the concrete slump measuring cylinder (5) is fixed on the base (6).
