[0002] In the construction industry, the quality of building materials is directly related to the safety, durability, and stability of buildings. Among these, the performance of building materials under impact is an important quality indicator.

[0003] Some impact height adjustment methods in testing devices are quite complex, often requiring manual operation of multiple mechanical components, such as adjusting the position of the impact component by fixing and loosening bolts. This is not only cumbersome to operate, but also makes it difficult to guarantee adjustment accuracy, failing to meet the needs of precise impact testing of different building materials at different heights. Therefore, this paper proposes an impact testing device for building materials to solve the above problems. Utility Model Content

A connecting plate is fixedly connected between opposite sides of the connecting blocks on both the left and right sides. An impact block is fixedly connected to the bottom of the connecting plate.

[0008] Furthermore, one end of the electric push rod is fixedly connected to a plug, and slots that match the plug are provided on opposite side walls of the connecting blocks on both the left and right sides.

[0009] Furthermore, a fixing plate is fixedly connected to each side of the frame on both the left and right sides, and a sliding rod is fixedly connected to the bottom of the fixing plate. The bottom end of the sliding rod is fixedly connected to the top of the base.

[0010] Furthermore, the inner side of the connecting block is provided with a sliding opening that matches the sliding rod, and the connecting block is slidably connected to the outer side of the corresponding sliding rod through the sliding opening.

[0011] Furthermore, the width of the impact block is equal to the width of the connecting plate, the threaded block on the left is located inside the left frame, and the threaded block on the right is located inside the right frame.

[0015] Compared with the prior art, this utility model provides a device for impact testing of building materials, which has the following beneficial effects:

[0016] This impact testing device for building materials uses a dual-axis motor to drive a transmission rod to rotate, which in turn drives a first bevel gear and a second bevel gear to rotate. This causes the threaded rod to rotate and move the threaded block up and down, ultimately adjusting the height of the impact block. The upward and downward movement of the impact block can be achieved simply by controlling the forward and reverse rotation of the dual-axis motor. At the same time, the threaded transmission has high precision and can accurately control the height position of the impact block, meeting the needs of precise impact testing of different building materials at different heights.

[0021] 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.

[0022] Please see Figs. 1-3 An impact testing device for building materials in this embodiment includes a base 1 and a frame 2 that is fixedly connected to the left and right sides of the top of the base 1 respectively. The inner side of the base 1 is provided with a testing component for testing.

[0023] Please see Fig. 1 In this embodiment, the detection component includes a dual-axis motor 3 fixedly connected to the inner bottom wall of the base 1. The output shaft of the dual-axis motor 3 is fixedly connected to a transmission rod 4. A first bevel gear 5 is fixedly connected to the outer side of the transmission rod 4. A second bevel gear 6 meshes with the top of the first bevel gear 5. A threaded rod 7 is fixedly connected to the inner side of the center of the second bevel gear 6. A threaded block 8 is threadedly connected to the outer side of the threaded rod 7. Mounting blocks 9 are fixedly connected to the opposite side of the left and right threaded blocks 8. Electric push rods 10 are fixedly connected to the opposite side of the left and right mounting blocks 9. A connecting block 11 is provided at one end of the movable rod of the left and right electric push rods 10. A connecting plate 12 is fixedly connected between the opposite sides of the left and right connecting blocks 11. An impact block 13 is fixedly connected to the bottom of the connecting plate 12.

[0024] Specifically, one end of the movable rod of the electric push rod 10 is fixedly connected to the insert block 14, and slots that are compatible with the insert block 14 are opened on the opposite side walls of the connecting blocks 11 on both the left and right sides.

[0025] It should be noted that this configuration allows the locking of the connecting block 11 to be released simply by pulling the plug 14 out of the slot.

[0026] Specifically, a fixing plate 15 is fixedly connected to the opposite side of the left and right frame bodies 2. A slide rod 16 is fixedly connected to the bottom of the fixing plate 15. The bottom end of the slide rod 16 is fixedly connected to the top of the base 1. A sliding opening adapted to the slide rod 16 is opened on the inner side of the connecting block 11. The connecting block 11 is slidably connected to the outer side of the corresponding slide rod 16 through the sliding opening.

[0027] It should be noted that the cooperation between the slide bar 16 and the sliding mouth provides guidance for the up and down movement of the connecting block 11, ensuring the stability of the connecting block 11 during movement and preventing it from shifting in the horizontal direction. This ensures that the impact block 13 can accurately impact the building materials and improve the accuracy of the test.

[0028] Specifically, the width of the impact block 13 is equal to the width of the connecting plate 12, the left threaded block 8 is located inside the left frame 2, and the right threaded block 8 is located inside the right frame 2.

[0029] Specifically, the right side inside the left frame 2 and the left side inside the right frame 2 are provided with limiting slides that are compatible with the mounting block 9.

[0030] Specifically, the left end of the left transmission rod 4 is rotatably connected to the inner left side wall of the base 1, and the right end of the right transmission rod 4 is rotatably connected to the inner right side wall of the base 1.

[0031] Specifically, the top end of the threaded rod 7 passes through the inner top wall of the base 1 and the threaded groove of the corresponding threaded block 8, and is rotatably connected to the inner top wall of the corresponding frame 2.

[0032] The working principle of the above embodiments is as follows:

[0033] Turn on the dual-axis motor 3, which is fixedly connected to the inner bottom wall of the base 1. The dual-axis motor 3 starts to run, and its output shaft drives the transmission rod 4 to rotate. When the transmission rod 4 rotates, it drives the first bevel gear 5, which is fixedly connected to its outer side, to rotate synchronously. When the first bevel gear 5 rotates, its top meshes with the second bevel gear 6, thereby driving the second bevel gear 6 to rotate. The inner side of the center of the second bevel gear 6 is fixedly connected to a threaded rod 7. Therefore, the rotation of the second bevel gear 6 will drive the threaded rod 7 to rotate. When the threaded rod 7 rotates, since the threaded rod 7 is threadedly connected to the threaded block 8, the rotation of the threaded rod 7 will drive the threaded block 8 to move up and down along the threaded rod 7. When the threaded block 8 moves up and down, it will drive the mounting block 9 to move up and down synchronously. The mounting block 9 will then drive the electric push rod 10, which is fixedly connected to it, to move up and down. The electric push rod 10 is connected to the connecting block 11 through the insert block 14, thereby driving the connecting block 11 to move up and down, thereby driving the connecting plate 12 and the impact block 13 to move up and down, thereby adjusting the height position of the impact block 13.

[0034] Once the impact block 13 is adjusted to the appropriate height, the movable rod of the electric push rod 10 retracts, causing the insert block 14 to be pulled out of the slot of the connecting block 11. At this time, the connecting block 11 loses its lock, thereby causing the impact block 13 to fall down along the slide rod 16 to impact the building materials. If it is necessary to perform impact tests at different heights again, the above steps can be repeated.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
