Description

Technical Field

[0001] The utility model relates to the technical field of concrete strength detectors, in particular to a concrete strength detector with a protective structure. Background Art

[0002] A concrete strength tester is a device used to measure the compressive strength of concrete. It is usually used at concrete construction sites or concrete product manufacturers to ensure the quality of concrete and that it meets design requirements. The concrete strength tester applies pressure or load to the concrete sample and calculates the compressive strength of the concrete through a related formula. The concrete strength tester can quickly and accurately measure the compressive strength of concrete, helping to ensure project quality and safety.

[0003] At present, when using concrete strength testers on the market, generally the concrete blocks to be tested are directly placed on a placement table for strength testing. The existing concrete strength testers squeeze the concrete blocks during the testing process, and the small fragments produced by the concrete blocks are easy to splash outwards. Therefore, we propose a concrete strength tester with a protective structure. Utility Model Content

[0008] Preferably, a connecting rod passes through the middle of the threaded sleeve, and both ends of the connecting rod are connected to the mounting seat and the connecting block through a bearing seat.

[0009] Preferably, a motor docking with the connecting rod is installed at the bottom of the connecting block, and guide blocks are connected to both sides of the placement table, and the guide blocks are docked and inserted inside the guide grooves.

[0010] Preferably, a movable plate is fitted on the lower surface of the top plate, and a connecting seat is provided on the upper edge of the movable plate, and the connecting seat is butt-jointedly sleeved on both side edges of the top plate.

[0012] Preferably, the bottom of the connecting pin is connected to a limiting block, and both ends of the spring are respectively connected to the limiting seat and the limiting block.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the concrete strength tester with a protective structure can prevent the fragments of the squeezed concrete blocks from splashing outward by arranging a protective cover that can move upward on the outer edge of the placement table, so that the concrete strength tester has a protective structure; and by arranging a movable plate that can be quickly disassembled under the top plate, it is convenient to replace the worn movable plate, thereby making the detection of the concrete strength tester more accurate.

[0014] 1. The upper end of the protective cover of the concrete strength tester with a protective structure is flush with the surface of the placement table in the initial shape. After the concrete block to be tested for strength is placed on the placement table, the connecting rod connected to the output end is driven to rotate synchronously by starting the motor. As the connecting rod rotates, the outer threaded sleeve drives the connected protective cover to move upward to the limit position synchronously. By arranging a protective cover that can move upward on the outer edge of the placement table, it is possible to prevent the fragments of the squeezed concrete block from splashing outward, so that the concrete strength tester has a protective structure;

[0015] 2. The concrete strength tester with a protective structure pulls the connecting pin upward to the extreme position. At this time, the limit block and the docking connecting seat are separated, and the worn movable plate can be disassembled. Then, the connecting seat on the new movable plate corresponds to the inner side of the limit seat, and the pulled connecting pin is loosened. The loosened connecting pin can automatically reset downward to the corresponding surface of the connecting seat through the elastic force of the spring, thereby completing the replacement of the movable plate. By arranging a quickly detachable movable plate under the top plate, it is convenient to replace the worn movable plate, thereby making the inspection of the concrete strength tester more accurate.

[0024] During specific implementation, the upper end of the protective cover 10 in the initial shape is flush with the surface of the placement table 4, and the through groove 12 on the protective cover 10 is correspondingly sleeved on the outer side of the connecting block 8. After the concrete block to be tested for strength is placed on the top of the placement table 4, the connecting rod 14 connected to the output end is driven to rotate synchronously by starting the motor 15. Since the connecting rod 14 and the threaded sleeve 13 are threadedly connected, the outer threaded sleeve 13 can drive the connected protective cover 10 to move upward synchronously with the rotation of the connecting rod 14. The moving protective cover 10 moves stably along the outer side of the guide block 16 through the guide grooves 11 opened on both sides of the inner wall, and as the protective cover 10 moves upward, the through groove 12 can gradually be misaligned with the connecting block 8 until the protective cover 10 is moved up to the extreme position.
