DETAILED DESCRIPTION

[0022] See also Figures 1 to 3 A concrete mortar consistency tester, comprising a mounting plate 8, wherein a downwardly concave threaded groove is provided at the center of the upper surface of the mounting plate 8, and an inverted frustum-shaped mortar bucket is screwed into the threaded groove through a threaded section at the bottom;

[0023] An L-shaped bracket 11 is provided on the upper surface of the mounting plate 8, with a fixing clip 12 at the end. A fastening bolt 13 is horizontally passed through the side wall of the fixing clip 12, and a scaled detection ruler 14 is clamped by the fastening bolt 13 and the fixing clip 12. The bottom end of the detection ruler 14 is detachably connected to a detection cone 15 through a connecting piece.

[0024] The connecting member includes a first support 16 arranged at the bottom of the detection ruler 14, and a first slide groove 17 is recessed upward on the lower surface of the first support 16. A connecting seat 18 protruding downward is provided on the top of the first slide groove 17, and also includes a second threaded rotating rod with a horizontal moving rod, and the horizontal moving rod and the second threaded rotating rod are rotatably connected through a rotating bearing; the second threaded rotating rod passes through the side wall of the first slide groove 17, and the horizontal moving rod passes through the connecting seat 18 and is connected to the first slider 19; a sliding plate 20 that can slide up and down is provided in the first slide groove 17, and a hinge seat is provided on the upper surface of the sliding plate 20, which is hinged to the inflection point of the L-shaped rotating frame 21. The L-shaped rotating frame 21 has a strip-shaped second slide groove 22 at each end of each side; it also includes a lifting rod 23 that vertically penetrates the sliding plate 20, and a horizontal second slider 24 is provided on the top of the lifting rod 23. The first slider 19 and the second slider 24 are respectively embedded in the second slide groove 22 at the ends of the L-shaped rotating frame 21; the lower end of the lifting rod 23 is also provided with a horizontal end plate 25, and the two ends of the end plate 25 are each hinged to a connecting head 26; the end of each connecting head 26 is hinged to a top plate 27, and the middle of each top plate 27 is hinged to a support plate 28, and the support plate 28 is connected to the lower surface of the sliding plate 20;

[0025] The detection cone 15 further includes a third slide groove 33 provided on the upper surface thereof. The bottom of the third slide groove 33 has buckle grooves extending to both sides. The ends of the top plate 27 are embedded in the buckle grooves when the lifting rod 23 is pressed downward.

[0026] The main principle of this utility model is as follows: When testing the mortar consistency, first pull up the measuring ruler 14 and the measuring cone 15, ensuring that the distance between the measuring cone 15 and the mortar in the bottom mortar bucket meets the standard requirements. Then, turn the fastening bolt 13, loosen the measuring ruler 14, and slowly lower the measuring ruler 14 and the measuring cone 15 until the bottom surface of the measuring cone 15 is flush with the mortar level in the mortar bucket. At this point, turn the fastening bolt 13 to fix the position of the measuring ruler 14 and the measuring cone 15. Then, turn the fastening bolt 13 in the opposite direction, loosen the measuring ruler 14, and the measuring cone 15 slowly sinks into the mortar in the mortar bucket. After the sinking time meets the standard requirements, tighten the fastening bolt 13 again and read the depth of the sinking of the measuring ruler 14. The sinking depth reading corresponds to the concrete consistency at that location. When disassembling the detection cone 15, the second threaded rod is first rotated. Driven by the second threaded rod, the first slider 19 is pushed horizontally, driving the L-shaped rotating frame 21 to rotate. Under the action of the L-shaped rotating frame 21, the lifting rod 23 on the other side is lifted. The end plate 25 then drives the top plate upward, pulling the connector 26 upward and pulling the end of the support rod 28 toward the inner and lower part, so that the detection cone 15 changes from the locked state to the released state. At this time, the detection ruler 14 and the detection cone 15 can be separated, making it easier to clean the detection ruler 14 and the detection cone 15 separately. When reinstalling after cleaning, the connector at the bottom of the detection ruler 14 is completely inserted into the detection cone 15, and the second threaded rod is rotated in the opposite direction to lock the detection ruler 14 and the detection cone 15.

[0027] As a further embodiment, a positioning protrusion 30 is provided on the lower surface of the first support 16 , and a positioning recess 31 matching the positioning protrusion 30 is provided on the upper surface of the detection cone 15 .

[0028] In this embodiment, the positioning protrusion 30 and the positioning recess 31 serve to quickly align the detection cone 15 and the detection ruler 14 , thereby increasing installation efficiency.

[0029] As a preferred embodiment, it also includes a base 1 with a mounting groove 2 on the upper surface, and the mounting plate 8 is covered on the base 1; a rotatable first threaded rod 3 is provided in the mounting groove 2 of the base 1, and the first threaded rod 3 passes through the side wall of the mounting groove 2; and further includes two moving blocks 5 slidably sleeved on the first threaded rod 3, and the moving blocks 5 are provided with vertical support rods 6, and the top of the support rod 6 is provided with a horizontal fixing head 7;

[0030] A vertical lifting plate 9 extending into the mounting groove 2 is further provided on the lower surface of the mounting plate 8 . An inclined groove 10 is provided on the vertical lifting plate 9 , and the end of the horizontal fixing head 7 extends into the inclined groove 10 .

[0031] In this embodiment, a solution for adjusting the experimental height is provided. Specifically, by rotating the first threaded rotating rod 3, the moving block 5 moves toward one side, thereby driving the vertical support rod 6 and the horizontal fixed head 7 on the top of the support rod 6 to move. The horizontal fixed head 7 is squeezed with the side wall of the inclined groove 10 in the inclined groove 10, thereby adjusting the height of the vertical lifting plate 9, thereby achieving the purpose of adjusting the experimental height, that is, the initial height of the mortar bucket, and avoiding the problem that the initial height of the mortar bucket is low and the detection cone 15 does not sink enough.

[0032] As a preferred embodiment, a horizontal observation slot 32 is provided on the side wall of the fixing clamp 12 .

[0033] In this embodiment, the thickness of the observation slot 32 is only slightly greater than the thickness of the scale lines on the detection ruler 14, so as to facilitate quick and direct measurement readings.

[0034] As a preferred embodiment, the first threaded rotating rod 3 passes through the mounting slot 2 and is connected to the crank 4 .

[0035] In this embodiment, the first threaded rotating rod 3 can be quickly rotated by the crank 4, which makes it convenient for construction workers to operate the device of the utility model.
