Description

Technical Field

[0001] This utility model relates to the field of impact testing technology, specifically to an impact resistance testing instrument for building materials. Background Technology

[0002] Building materials are various raw materials used in building structures and components, such as steel, concrete, and wood, which play a role in supporting, protecting, and beautifying buildings. To ensure that these materials have sufficient toughness and strength when encountering sudden external forces or vibrations, and to avoid breakage, deformation, or failure, thereby ensuring the safety, durability, and stability of the building, they are subjected to impact tests.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN218725937U) discloses an impact testing device for building materials, comprising an impact testing platform. The impact testing platform includes a supporting upright plate, a fixed base plate, and a fixed top plate. The fixed base plate is welded and fixed to the lower end between two supporting upright plates, and the fixed top plate is welded and fixed to the upper end between two supporting upright plates. Fixed uprights are welded and fixed at the four corners of the upper end of the fixed base plate. The upper ends of the fixed uprights extend through the fixed top plate to the upper end of the fixed top plate. The fixed top plate is welded and fixed to the fixed uprights. An upper limit sliding plate is provided at the upper end of the fixed top plate, and the upper limit sliding plate is slidably connected to the fixed uprights. A lifting drive motor is installed in the middle of the upper end of the upper limit sliding plate, and a threaded rod is installed at the lower end of the upper limit sliding plate along the output shaft end of the lifting drive motor.

[0004] Although the aforementioned patent uses a lifting drive motor to drive a threaded rod to rotate, with the threaded rod threadedly connected to a fixed sleeve, pulling the upper limit sliding plate and the lifting drive motor mounted on its upper end upwards, the winding drive assembly drives the worm gear away from the rotating worm wheel. At this point, the rotating worm wheel loses its function of limiting the rotation of the worm gear. Without a limiting structure to stop the rotating worm wheel, the lower sliding plate and its lower end structure fall freely downwards under gravity, impacting the test block. The magnitude of the impact force can be clearly obtained from the weight of the lower sliding plate and its lower end structure combined with the fall height, accurately determining the impact resistance of the test block. However, relying on gravity and the weight of the test block itself, the impact force is affected by changes in gravity, friction, and mechanical structural errors, making it difficult to precisely control and repeat, and easily affecting the stability of the test results.

[0005] Therefore, this utility model provides an impact resistance testing instrument for building materials to solve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides an impact resistance testing instrument for building materials, such as... Figures 1-5 As shown, the building material impact resistance testing instrument includes a base plate 1, and upright plates 2 are fixedly connected to both sides of the upper surface of the base plate 1. A drive assembly is fixedly installed on the outer side of one of the upright plates 2.

[0030] The drive assembly includes a motor 3, one side of which is fixedly mounted on one side of one of the upright plates 2. A rotating rod 4 is fixedly connected to the output end of the motor 3, and a striking rod 5 is fixedly connected to the middle of the outer surface of the rotating rod 4. When the motor 3 is started, the striking rod 5 can be rotated via the rotating rod 4 to raise the height of the controller. Subsequently, the motor 3 can be reversed to precisely control its falling speed, thereby adjusting the impact force generated when it strikes. This enables precise setting and digital management of experimental parameters, thereby improving the accuracy and flexibility of operation, facilitating the reproduction of repeated test conditions, and effectively ensuring the consistency of the test process and the stability of the results.

[0031] Positioning components are fixedly connected to both sides of the outer surface of the rotating rod 4.

[0032] The positioning assembly includes a telescopic rod 6, the bottom end of which is fixedly connected to one side of the outer surface of the rotating rod 4. A connecting ring 7 is fixedly connected to the top end of the telescopic rod 6. A locking rod 8 is rotatably connected inside the connecting ring 7. A first spring 9 is fixedly connected to the lower surface of the connecting ring 7 on the periphery of the telescopic rod 6. A slot adapted to the locking rod 8 is opened on the upper surface of the upright plate 2. When the striking rod 5 strikes the building material, the locking rod 8 will rotate to the top of the slot. The first spring 9 can pull the connecting ring 7 to move the locking rod 8 downward quickly, so that the locking rod 8 is engaged in the slot. This accurately positions and fixes the striking rod 5, effectively preventing displacement or repeated striking due to vibration during operation. This further ensures the consistency of the striking force and position each time, thereby significantly improving the accuracy and repeatability of the test results.

[0033] One end of the rotating rod 4 is fixedly connected to an indicator needle 10, while the outer side of the other side of the upright plate 2 is fixedly connected to a circular disk 11. The indicator needle 10 is in contact with the surface of the circular disk 11. When the rotating rod 4 rotates, it can drive the indicator needle 10 to rotate. By referring to the scale line on the circular disk 11, the height of the striking rod 5 can be known. The rotation height data can be compared in real time to ensure the accuracy of the test results.

[0034] A fixing plate 12 is fixedly connected to both the front and back surfaces of the upright plate 2, and a push assembly is threadedly connected to the center of the front surface of the fixing plate 12.

[0035] The push assembly includes a threaded rod 13, the outer surface of which is threaded to the center of the front surface of the fixed plate 12. One end of the threaded rod 13 is rotatably connected to the push plate 15 via a bearing 14. The threaded rod 13 can push the push plate 15 by rotating the threaded rod to compress and fix the building material, thereby achieving stable clamping of the sample.

[0036] Guide rods 16 are fixedly connected to both the upper and lower sides of the front surface of the push plate 15. A second spring 17 is sleeved on the outer surface of the guide rod 16 between the push plate 15 and the fixed plate 12. The guide rod 16 guides the second spring 17, so that the second spring 17 can push the upper and lower sides of the push plate 15 to ensure the uniformity of the force on the push plate 15.

[0037] A connector 18 is fixedly connected to the bottom of the back of the striking rod 5. A striking head 19 is slidably connected inside the connector 18. The upper surface of the outer surface of the striking head 19 is threadedly connected to the upper surface of the outer surface of the connector 18 by a bolt 20. The striking head 19 can be removed by unscrewing the bolt 20 for replacement. This allows for the replacement of striking heads 19 with different materials or shapes according to different testing needs, thereby expanding the applicability and testing accuracy of the equipment.

[0038] Working steps: First, the threaded rod 13 pushes the push plate 15 to compress and fix the building materials. Then, the guide rod 16 guides the second spring 17, which pushes the upper and lower sides of the push plate 15 to ensure uniform force distribution. Next, the starter motor 3 drives the striking rod 5 to rotate via the rotating rod 4 to control the height. At the same time, the rotating rod 4 drives the indicator needle 10 to rotate, and the scale on the circular disc 11 is used as a reference. Then, the motor 3 is reversed to precisely control the falling speed. Second, when the striking rod 5 strikes the building materials, the clamping rod 8 rotates to the top of the clamping slot. The first spring 9 pulls the connecting ring 7 to move the clamping rod 8 quickly downward, so that the clamping rod 8 is engaged in the clamping slot, thereby accurately positioning and fixing the striking rod 5. Finally, the bolt 20 is unscrewed to remove the striking head 19 for replacement.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
