[0001] The utility model relates to the technical field of gypsum board testing equipment, in particular to a testing device for the adhesion of light plastering gypsum. Background Technique

[0002] Light plastering gypsum is an indoor wall plastering and leveling material prepared by taking building gypsum powder as a gelling material and adding a variety of additives and lightweight aggregates. It has the advantages of rich raw materials, low price, simple production process, convenient construction, good heat preservation effect, etc., and is a new type of building engineering material; when in use, the light plastering gypsum is mixed with water to form a paste, and then workers use a mortar board and a trowel to apply the light plastering gypsum on the wall. The specific operation is that the worker needs to first put the paste-like light plastering gypsum on the mortar board, and then carry it to the wall and apply it on the wall with a trowel.

[0003] According to a disclosed testing device for the adhesion of light plastering gypsum (Publication No.: CN219935639U), in the above application, a dynamometer is used to pull a test board, and the pulling force value when the test board detaches from the light plastering gypsum is recorded, and at the same time, the area when the test board contacts the light plastering gypsum is measured; according to the formula: S = F / Al to calculate the tensile strength, that is, the viscosity of the light plastering gypsum, where S is the tensile strength, the unit is: megapascal, F is the pulling force value, the unit is: Newton (N), and Al is the contact area between the light plastering gypsum and the test board, the unit is square centimeter.

[0004] In the above, the test board is pulled by a dynamometer to make the test board detach from the light plastering gypsum, so that the viscosity value of the light plastering gypsum can be obtained through calculation of the data of the test board. However, when the test board is placed into the light plastering gypsum, it may not be completely adhered, resulting in the generation of bubbles. In this way, it may affect the accuracy of the data during the pulling test. Content of the Utility Model

Detailed implementation mode

[0023] As Figures 1-5 shown, the present utility model provides a technical solution: a light plastering gypsum adhesion testing device, including a testing table 1, a support frame 2 is fixedly installed on the top of the testing table 1, a first cylinder 3 is fixedly installed at the bottom of the support frame 2, the output end of the first cylinder 3 is piston-connected with a first piston rod 4, a sliding block 5 is fixedly installed on the right side of the first piston rod 4, the top of the sliding block 5 is slidably installed at the bottom of the support frame 2, a second cylinder 6 is fixedly installed at the bottom of the sliding block 5, the output end of the second cylinder 6 is piston-connected with a second piston rod 7, a first hook 8 is fixedly installed at the bottom of the second piston rod 7, a dynamometer 9 is attached to the outer wall of the first hook 8, a second hook 10 is fixedly installed at the bottom of the dynamometer 9, a testing box 11 is fixedly installed on the top of the testing table 1, a light plastering gypsum 12 is attached to the inside of the testing box 11, a test plate 13 is attached to the top of the light plastering gypsum 12. Place light plastering gypsum with different ratios in different slots of the testing box 11, level it and then put in the test plate 13. Then start the first cylinder 3 to make the first piston rod 4 drive the sliding block 5 to move. When it moves to a suitable position, start the second cylinder 6 to make the second piston rod 7 drive the first hook 8 to move downward, so that the dynamometer 9 moves downward. Then hang the test plate 13 on the second hook 10, and then make the second piston rod 7 move back to detect its viscosity. A knocking mechanism 14 is arranged on the top of the testing table 1, which can eliminate the bubbles between the test plate 13 and the light plastering gypsum 12. A blocking mechanism 15 is arranged on the top of the testing table 1.

[0024] Specifically, the knocking mechanism 14 includes: an L-shaped plate 141, a fixed column 142, a connecting rod 143, a moving rod 144, a shielding block 145, a rotating rod 146, a pressing rod 147, a first torsion spring 148, a fixed block 149, a rotating shaft 1410, a swinging rod 1411, a second torsion spring 1412, and a knocking hammer 1413. The through hole of the L-shaped plate 141 is fixedly installed on the outer wall of the second piston rod 7. The front surface of the L-shaped plate 141 is fixedly installed with a fixed column 142. The outer wall of the fixed column 142 is attached to the connecting rod 143. One end of the connecting rod 143 away from the fixed column 142 is hinged to the moving rod 144. The bottom of the moving rod 144 is slidably installed on the top of the detection table 1. The shielding block 145, the bottom of the shielding block 145 is fixedly installed on the top of the moving rod 144. The right side of the shielding block 145 is fixedly installed with a rotating rod 146. The outer wall of the rotating rod 146 is rotatably installed with a pressing rod 147. The right side of the pressing rod 147 is fixedly installed with a first torsion spring 148. When the moving rod 144 returns to its original position, the pressing rod 147 will be squeezed by the swinging rod 1411, and the pressing rod 147 rotates in the reverse direction and is not blocked by the shielding block 145. At this time, it will rotate on the outer wall of the rotating rod 146, and the first torsion spring 148 twists. One end of the first torsion spring 148 away from the pressing rod 147 is fixedly installed on the outer wall of the rotating rod 146. The right side of the detection box 11 is fixedly installed with a fixed block 149. The through hole of the fixed block 149 is rotatably installed with a rotating shaft 1410. The left side of the rotating shaft 1410 is fixedly installed with a swinging rod 1411. The right side of the fixed block 149 is fixedly installed with a second torsion spring 1412. When the second piston rod 7 moves downward, it drives the L-shaped plate 141 to move downward, so that the fixed column 142 squeezes the connecting rod 143, causing the two moving rods 144 to move to both sides. And when moving, the pressing rod 147 squeezes the swinging rod 1411. At this time, the pressing rod 147 is stuck by the shielding block 145, making it unable to rotate forward. Thus, the swinging rod 1411 drives the rotating shaft 1410 to rotate, and the second torsion spring 1412 twists. One end of the second torsion spring 1412 away from the fixed block 149 is fixedly installed on the outer wall of the rotating shaft 1410. The outer wall of the rotating shaft 1410 is fixedly installed with a knocking hammer 1413. When the pressing rod 147 is squeezed past, the second torsion spring 1412 will reset the rotating shaft 1410, so that the knocking hammer 1413 strikes the detection box 11, eliminating the bubbles between the test plate 13 and the lightweight plaster 12.

[0025] Specifically, the shielding mechanism 15 includes: a return groove 151, a spring 152, a return plate 153, and an extrusion block 154. The return groove 151 is opened at the top of the detection box 11. A spring 152 is fixedly installed at the bottom of the return groove 151. Through the above middle connecting rod 143, the moving rod 144 will be driven to move. At this time, the connecting rod 143 will also move downward, causing the extrusion block 154 to extrude the return plate 153 to move into the return groove 151, and the spring 152 is compressed. One end of the spring 152 away from the return groove 151 is fixedly installed with the return plate 153. The outer wall of the return plate 153 is slidably installed inside the return groove 151. The extrusion block 154 is fixedly installed on the back of the connecting rod 143. When the connecting rod 143 moves upward, the spring 152 will reset the return plate 153, preventing the test plate 13 from shaking and falling off when it is separated from the lightweight plaster 12, and also preventing the lightweight plaster 12 from splashing, thus causing injury to the tester.

[0026] Working principle: Place lightweight plaster 12 with different ratios in different slots of the detection box 11. After leveling it, put the test plate 13 in, and then start the first cylinder 3, so that the first piston rod 4 drives the sliding block 5 to move. At this time, the L-shaped plate 141 will drive the fixed column 142 to move and pass through the through hole of the connecting rod 143, but will not separate from the connecting rod 143. When it moves to the appropriate position, start the second cylinder 6, so that the second piston rod 7 drives the first hook 8 to move downward, thereby driving the dynamometer 9 to move downward. When moving downward, the fixed column 142 will squeeze the connecting rod 143, causing the two moving rods 144 to move to both sides. And when moving, the extrusion rod 147 will squeeze the swing rod 1411. At this time, the extrusion rod 147 is blocked by the blocking block 145 and cannot rotate forward, so that the swing rod 1411 drives the rotating shaft 1410 to rotate, and the second torsion spring 1412 twists. After the extrusion, the second torsion spring 1412 will reset the rotating shaft 1410, causing the knocking hammer 1413 to knock on the detection box 11. When the moving rod 144 resets, the extrusion rod 147 will be squeezed by the swing rod 1411. The extrusion rod 147 rotates in the reverse direction and is not blocked by the blocking block 145. At this time, it will rotate on the outer wall of the rotating rod 146, and the first torsion spring 148 twists. After the extrusion, the first torsion spring 148 will reset the extrusion rod 147. In this way, when the second piston rod 7 moves downward, it can knock on the detection box 11, and does not knock when moving upward. In this way, after the test plate 13 is placed, the air bubbles between the test plate 13 and the lightweight plaster 12 can be eliminated, preventing inaccurate test data caused by air bubbles.

[0027] Through the above-mentioned middle connecting rod 143, the moving rod 144 will be driven to move. At this time, the connecting rod 143 will also move downward, causing the extrusion block 154 to extrude the return plate 153 into the return groove 151, and the spring 152 is compressed. This can facilitate the second hook 10 to hang the test plate 13. When the connecting rod 143 moves upward, the spring 152 will reset the return plate 153, preventing the test plate 13 from shaking and falling when the test plate 13 is separated from the lightweight plaster 12, and also preventing the lightweight plaster 12 from splashing, thus causing injury to the tester.

[0028] The above text generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
