DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-7 The utility model discloses a constant load concrete pressure test detection machine, including a base 1, a support rod 2, and a top plate 3. The top plate 3 is threadedly connected with a screw rod 4, and the bottom end of the screw rod 4 is fixedly connected with a pressure plate 5. The base 1 is provided with a carrier plate 6 driven by a hydraulic cylinder, and slots 7 are provided on both sides of the top of the base 1. The slots 7 are slidably connected with a protective baffle 8 that is U-shaped as a whole. Male buckles 10 are installed on the top and bottom of both sides of the protective baffle 8. Female buckles 11 that are matched with the male buckles 10 are provided on both sides of the base 1 and the top plate 3, and the protective baffle 8 is movably connected to a movable baffle 9.

[0022] The slot 7 is located at the top rear end of the base 1 and is open so that the two side panels of the protective baffle 8 can be inserted therein.

[0023] The side panels on both sides of the protective baffle plate 8 are movably connected to the slots 7 , and the bottom of the top plate 3 can also be provided with slots 7 movably connected to the side panels on both sides of the protective baffle plate 8 .

[0024] Specifically, the top and bottom of the movable baffle plate 9 close to the carrier plate 6 are both provided with T-shaped grooves 12 , and the front side of the protective baffle plate 8 is fixedly connected with a T-shaped block 13 that matches and slides with the T-shaped groove 12 .

[0025] In this embodiment, the movable baffle plate 9 can be installed by aligning its T-shaped slot 12 with the T-shaped block 13 on the front side of the protective baffle plate 8 and inserting it, so that the movable baffle plate 9 can be moved horizontally.

[0026] Specifically, an adjusting bolt 14 is threadedly connected to one end of the front side of the movable baffle 9 .

[0027] In this embodiment, the adjusting bolt 14 is screwed so that its end extends into the inner cavity of the protective baffle 8. The end of the adjusting bolt 14 can cooperate with the side wall of the protective baffle 8 to limit the maximum movement distance of the movable baffle 9 in one direction.

[0028] Specifically, one end of the front side of the movable baffle 9 away from the adjusting bolt 14 is fixedly connected to a fixed block 16, and a second movable groove 18 is opened on the fixed block 16. The inner wall of one side of the second movable groove 18 is connected to a movable baffle rod 21 that penetrates the movable baffle 9 through a spring, and the end of the baffle rod 21 can extend into the inner cavity of the protective baffle 8.

[0032] When the end of the blocking rod 21 does not extend into the inner cavity of the protective baffle 8, the movable baffle 9 can move in one direction.

[0033] The setting of the fixed block 16 facilitates the movement of the movable baffle 9. Pressing the pressing rod 19 can contact the inclined inner wall of the through hole 22 through the inclined groove 20 to drive the baffle rod 21 to move, so that the end of the baffle rod 21 does not extend into the inner cavity of the protective baffle 8.

[0034] Specifically, the movable baffle 9 is provided with a mesh hole 15 between the two T-shaped slots 12 .

[0035] To sum up, the constant load concrete pressure test detection machine, the cooperation of the protective baffle 8 and the movable baffle 9 can shield the concrete during the pressure test.
