Description

Technical Field

[0001] This utility model relates to the field of mortar sampling technology, and in particular to a mortar sampling and testing device. Background Technology

[0002] Mortar is a bonding material used in bricklaying in construction. It is made by mixing sand and cementing materials with water in a certain proportion. Freshly mixed ordinary mortar should have good workability, while hardened mortar should have the required strength and adhesion. The workability of mortar is related to its fluidity and water retention, which is generally determined by construction experience or through testing. Traditional mortar is paste-like.

[0003] Currently, mortar sampling and testing often involves using a spoon to dig out the upper layer of mortar, but it is difficult to extract the deeper layers, making it impossible to test the mortar at different depths and affecting the accuracy of the test. Therefore, we have designed a mortar sampling and testing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mortar sampling and testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mortar sampling and testing device includes a pipe body with a conical head at one end and an installation rod inside the pipe body. The two ends of the installation rod are respectively provided with a second thread and a third thread. The second thread is fixed to a screw hole on the conical head, and the third thread is connected to a pressing mechanism. A guide plate with a central hole is inserted on the installation rod and is located close to the conical head. The top of the guide plate is provided with an inclined surface.

[0007] Preferably, the guide plate has an installation groove at the inclined surface, and the outer wall of the installation rod has a first thread near the inclined surface, and a first threaded sleeve is threaded onto the first thread, the first threaded sleeve pressing the guide plate tightly against the conical head.

[0008] Preferably, a partition is fixed to the inner wall of the tube, and the partition has a hole for the installation rod to pass through. The partition is located close to the guide plate.

[0009] Preferably, the end of the tube body away from the conical head is threadedly connected to a cap, and the cap has a hole for the installation rod to pass through. The pressing mechanism includes an installation plate, and a second threaded cap is fixed at the center of the installation plate. The second threaded cap is threadedly connected to a third thread. A spring is sleeved on the part of the installation rod that passes through the cap. A first pressing arm is fixed to the bottom of the cap, and a second pressing arm is fixed to the bottom of the installation plate. A threaded hole is opened on the outer wall of the first pressing arm, and an insertion hole is opened on the second pressing arm. A double-ended screw is inserted into the insertion hole. One end of the double-ended screw is threadedly connected to the threaded hole, and the other end of the double-ended screw is threadedly connected to a third nut. The conical head and the installation rod are detachable. The guide plate is pressed close to the conical head by the first threaded sleeve. The double-ended screw is detachable. The installation plate and the installation rod are detachable and connected by the second threaded cap. The conical head can be removed first, then the double-ended screw can be removed, then the installation plate can be removed, the spring can be taken out, and finally the cap can be removed, which facilitates the removal of the installation rod and realizes the overall disassembly. Replacement parts can be made available.

[0010] Preferably, the outer wall of the pipe has a marking groove at the top of the inclined surface. When the pipe is inserted, it is ensured that the marking groove is facing upwards and it is inserted into the mortar at an angle, so that the mortar inside can slide down the inclined surface and be collected after insertion.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. Because it is equipped with a tube body, a conical head, an installation rod, a cap, and a pressing mechanism, after inserting the tube body at an angle, pressing is performed by holding the first and second pressing arms. The conical head moves away from the tube body, at which point the guide plate moves out of the tube body, and the mortar slides into the interior of the tube body along the inclined surface. Then, the pressing of the first and second pressing arms is released, the conical head returns to its original position and seals the tube body, and the collected mortar is located between the guide plate and the partition plate. The tube body is then pulled out to collect the sample, and finally, pressing is performed again to release the collected mortar. This effectively solves the problems raised in the background technology. It can be inserted to different depths as needed for sampling, and the sampling is small and controllable. It is convenient to use and easy to carry.

[0013] 2. The conical head and mounting rod are detachable. The guide plate is pressed close to the conical head by the first threaded sleeve. The double-ended screw is detachable. The mounting plate and mounting rod are detachable and connected by the second threaded cap. The conical head can be removed first, then the double-ended screw can be removed, then the mounting plate can be removed, the spring can be taken out, and finally the cap can be removed to facilitate the removal of the mounting rod, so as to achieve overall disassembly and replacement of parts.
