[0020] Embodiment 1

[0021] like Figure 1 As shown, the utility model provides a device for testing the impact resistance of building materials, including a power mechanism and a fixing mechanism. The power mechanism is used to provide power for the impact resistance testing experiment of building materials, and the fixing mechanism is used to fix the building materials to prevent displacement during the impact resistance experiment.

[0022] The power mechanism is placed above the fixed plate 7, which is used to provide support for the power mechanism. Two limit holes are provided on the fixed plate 7, and the limit holes are used to pass the limit assembly. The power mechanism includes a first motor 1, and a half gear 2 is fixedly sleeved on the output shaft of the first motor 1. The first motor 1 is used to provide power for the rotation of the half gear 2. The teeth of the half gear 2 are engaged with the caliper 3, and the rotation of the half gear 2 drives the caliper 3 to move upward. The caliper 3 is connected to the limit mechanism, and the limit mechanism is used to limit the caliper 3 to prevent the caliper 3 from swinging left and right. An impact head 4 is connected below the caliper 3, and the impact head 4 is used to perform impact resistance testing on building materials.

[0023] The limiting mechanism includes a first limiting assembly and a second limiting assembly, the first limiting assembly and the second limiting assembly have the same structure and are respectively placed on both sides of the caliper 3. The first limiting assembly includes a limiting rod 5, the limiting rod 5 passes through the limiting hole, the limiting hole provides space for the installation of the limiting rod 5 and limits the limiting rod 5. Both ends of the limiting rod 5 are respectively fixedly connected to the limiting blocks 6, and the limiting blocks 6 are used to fix the limiting rod 5.

[0024] The fixing mechanism includes a second motor 8, which is connected to a telescopic rod 9, and the second motor 8 is used to provide power for the telescopic rod 9. The telescopic rod 9 is fixedly connected to a limit plate 10, and the telescopic rod 9 is used to drive the limit plate 10 to move. A slider is fixedly connected below the limit plate 10, and the slider is used to limit the limit plate 10 to prevent the limit plate 10 from shaking during movement. The slider is placed in a slide rail 11, and the slide rail 11 is opened on the base 12, and the slide rail 11 provides a track for the movement of the slider. Gaskets 13 are respectively provided at the four corners below the base 12, and the gaskets 13 can increase the friction between the base 12 and the contact surface to prevent displacement during the detection process. Four support columns 14 are provided between the base 12 and the fixed plate 7, and the support columns 14 are used to connect the base 12 and the fixed plate 7 and provide support for the installation of the fixed plate 7.

[0025] When using the building material impact resistance detection device provided by the utility model, the building material to be detected is first placed on the base 12, and then the second motor 8 is started. The second motor 8 drives the telescopic rod 9 to extend. The two second motors 8 are started at the same time, which can make the two limit plates 10 contact the building material at the same time, so that the building material is fixed in the center position of the base 12.

[0026] Then start the first motor 1, which drives the half gear 2 to rotate. When the toothed side of the half gear 2 meshes with the caliper 3, the half gear 2 drives the caliper 3 to move upward. When the toothless part of the half gear 2 rotates to contact the caliper 3, the caliper 3 moves downward, and the impact head 4 falls freely onto the building material to generate an impact force on the building material. After a certain period of time after the impact head 4 hits the building material, the toothed half side of the half gear 2 rotates back to the caliper 3, and the impact head 4 is driven to move upward again by the rotation of the half gear 2 until the next fall of the impact head 4, so as to perform repeated impact tests on the building material to detect the impact resistance of the building material under continuous impact.

[0027] Therefore, the utility model adopts the above-mentioned building material impact resistance detection device, which has a simple structure and is easy to operate. By setting a power mechanism, the impact head is made to impact the building material repeatedly, thereby detecting the impact resistance of the building material, and the force of each impact of the impact head is the same, which can meet the use needs.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
