Description
Technical Field
[0001] This utility model relates to the field of concrete testing technology, specifically a concrete air content measuring instrument. Background Technology
[0002] The assessment of concrete strength should be carried out in batches. The concrete in the same acceptance batch should be composed of mixed concrete with the same strength grade, mix proportion and basically the same production process. For cast-in-place concrete, the acceptance batch should be divided according to the sub-projects, and for precast concrete components, the batch should be divided according to the month. For the concrete strength of the same acceptance batch, the representative value of the strength of all standard test specimens retained in the batch should be used as statistical data for assessment.
[0003] Regarding the above-mentioned and existing related technologies: When testing concrete, it is necessary to measure the air content of the concrete. The use of specialized equipment is required for measuring the air content of concrete. Most air content measuring instruments have their lids and tanks fixed by threads, which requires multiple identical operations during installation and disassembly, resulting in cumbersome operation. Therefore, a concrete air content measuring instrument is proposed to address the above problems. Utility Model Content

The fixing device includes two placement plates, which are located on both sides of the tank. Two collars are fitted on the surface of the tank and the lid. A moving block is fixedly connected to the bottom end of the collar near the placement plate. A guide rod is fixedly connected to the inner surface of the placement plate. The surface of the guide rod and the inner wall of the moving block are slidably connected. The moving block slides on the inner wall of the placement plate and the surface of the guide rod. The collar will fit on the surface of the tank and the lid. By setting the placement plate, the guide rod, the collar, and the moving block, the position of the lid on the surface of the tank can be restricted.
[0006] Preferably, a placement block is fixedly connected to the side wall of the placement plate, and a slider is slidably connected to the inner wall of the placement block. When the slider moves, it slides on the inner wall of the placement block, and the placement block can support the slider.
[0007] Preferably, a sleeve block is fixedly connected to the upper surface of the slider, and a locking block is fixedly connected to the surface of each of the two collars near the sleeve block. The sleeve block is fitted onto the surface of the two locking blocks. When using the sleeve block, pushing the sleeve block allows it to fit onto the surface of the two locking blocks. The sleeve block and the locking blocks can restrict the position between the two collars.
[0008] Preferably, a rubber sleeve is fixedly connected to the inner surface of the sleeve block. The rubber sleeve is fitted over the surfaces of the two locking blocks. When the sleeve block moves, the rubber sleeve will press against the surfaces of the two locking blocks, thereby increasing the friction between the sleeve block and the locking blocks.
[0009] Preferably, the surface of the tank is provided with a placement device, which includes a fixing ring and a gasket. The fixing ring is sleeved on the surface of the tank, and a pad is fixedly connected to the side wall of the fixing ring. The gasket is located on the upper surface of the pad and is a rubber gasket. Concrete is mixed on the gasket. By setting the fixing ring, pad, and gasket, the situation of concrete contamination on the ground can be reduced, and the residual concrete can be easily cleaned up.
[0010] Preferably, four limiting posts are fixedly connected to the upper surface of the pad, and the gasket is sleeved on the surface of the limiting posts. When the gasket moves, the gasket will pass through the limiting posts. By setting the limiting posts, the random movement of the gasket can be reduced.
[0011] Preferably, a clamping ring is fixedly connected to the side wall of the fixing ring. The clamping ring is sleeved on the surface of the tank and fixed to the side wall of the fixing ring. The position of the pad can be restricted by setting the clamping ring and the fixing ring.
[0012] The advantages of this utility model are:
[0013] 1. When it is necessary to fix the lid and the can body, the present invention involves placing two placement plates on the surface of the can body, then pushing the collar to make the collar drive the moving block and the locking block to slide. The moving block slides on the inner wall of the placement plate and the surface of the guide rod, and the two locking blocks will fit together. Then, pushing the sleeve block to make the sleeve block drive the slider to slide on the inner wall of the placement block. When the sleeve block moves, it will drive the rubber sleeve to move. The rubber sleeve will be squeezed and fitted onto the surface of the two locking blocks. By setting the entire device, the lid and the can body can be easily fixed together, reducing the cumbersome operation of traditional fixing operations, thereby increasing the efficiency of installation and disassembly.
[0014] 2. When using the tank, the fixing ring and clamping ring are fixed to the surface of the tank. Then, the gasket is placed on the upper surface of the pad plate and passed through the limiting post. The position of the gasket is restricted by the limiting post. Then, the concrete is placed on the upper surface of the gasket, allowing the concrete to mix on the gasket. By setting up the whole device, it is convenient to mix concrete and also convenient to clean up residual concrete. Attached Figure Description
