[0021] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a building material impact detection device of the present utility model with reference to the accompanying drawings.

[0022] As Figures 1 to 3 shown, a building material impact detection device of the present utility model includes a base 1 for placing building materials, a top plate 3 disposed above the base 1 through support pillars 2, and the support pillars 2 are distributed at the four corners of the base 1. An impact member for performing impact testing on building materials is provided on the top plate 3. Specifically, the impact member includes a guide cylinder 5 provided on the bottom surface of the top plate 3, and a limit groove 51 is axially formed on the guide cylinder 5. An impact head 6 is slidably disposed in the guide cylinder 5, and a first limit plate 7 slidably disposed in the limit groove 51 is provided at the top end of the impact head 6. After the building material is placed on the base 1, the impact head 6 is lifted to an appropriate height through the first limit plate 7, and then the first limit plate 7 is released, so that the first limit plate 7 and the impact head 6 fall freely to perform impact testing on the building material on the base 1.

[0023] Preferably, a lifting device 4 is provided on the top plate 3. A lifting plate 9 is provided on the lifting device 4, and a fastening assembly 10 cooperating with the impact member is provided on the lifting plate 9. A through hole 92 for the impact member to pass through is also formed in the lifting plate 9. Through the lifting device 4, the lifting plate 9, and the fastening assembly 10, the lifting device 4 lifts the lifting plate 9, and the fastening assembly 10 on the lifting plate 9 is used to cooperate with the impact member to complete the connection between the fastening assembly 10 and the impact member. Then, the lifting device 4 drives the impact member to rise through the lifting plate 9 and the fastening assembly 10, thereby reducing the manual labor intensity and improving the work efficiency. Specifically, the lifting device 4 includes a screw rod 41 rotatably provided between the top plate 3 and the base 1. The top end of the screw rod 41 penetrates through the top plate 3 and is rotatably arranged with the top plate 3. The screw rod 41 is symmetrically arranged with respect to the center of the top plate 3. Belt pulleys 43 are provided on both screw rods 41, and the belt pulleys 43 are connected by a transmission belt 44. A motor 42 is further provided on the top surface of the top plate 3. The motor 42 is connected to an external power supply for power supply, and the output end of the motor 42 is connected to one of the screw rods 41. Among them, the lifting plate 9 is penetrated by the two screw rods 41 and is threadedly connected thereto. For the convenience of subsequent understanding, the screw rod 41 connected to the motor 42 is named the driving screw rod, the belt pulley 43 connected thereto is the driving belt pulley, and the other screw rod 41 is the driven screw rod, and the belt pulley 43 connected to the driven screw rod is the driven belt pulley.

[0024] The fastening component 10 for connecting with the impact piece includes a first inclined block 101 slidably arranged on the lifting plate 9. The inclined surface of the first inclined block 101 faces downward. A first chute 91 for the first inclined block 101 to slide is formed on the lifting plate 9, and a first guide post 102 passing through the first inclined block 101 and slidably arranged with the first inclined block 101 is arranged in the first chute 91. A retaining piece 103 for limiting the first inclined block 101 is arranged at the free end of the first guide post 102. A first spring 104 is also sleeved on the first guide post 102, and the first spring 104 is located between the first chute 91 and the first inclined block 101. When it is necessary to lift the impact piece, the motor 42 can be started. The motor 42 drives the connected driving screw 41 to rotate. The driving screw 41 drives the connected driving pulley 43 to rotate. Then, through the transmission belt 44, the driven pulley is driven to rotate, so that the driven screw connected to the driven pulley rotates. In this way, the two screws 41 can rotate at the same speed and in the same direction, making the lifting plate 9 connected to the two screws 41 move more smoothly during the lifting process. When the lifting plate 9 descends, it will drive the unlocking component 11 arranged thereon to descend. When the unlocking component 11 descends to the position where the first inclined block 101 arranged thereon contacts the first limiting plate 7, the first inclined block 101 will slide outward in the first chute 91 of the lifting plate 9 along its inclined surface, so that the first inclined block 101 slides over the first limiting plate 7, and the first inclined block 101 compresses the first spring 104 when sliding. When the first inclined block 101 slides over the first inclined block 101, the first spring 104 pushes the first inclined block 101 to move towards the inside of the lifting plate 9 and moves until the inclined surface of the first inclined block 101 is limited and stopped by the retaining piece 103. At this time, the vertex angle of the first inclined block 101 is located below the first limiting plate 7. Then, the motor 42 is started, and the motor 42 rotates in the reverse direction, driving the driving screw to rotate in the reverse direction. Under the action of the driving pulley, the driven pulley and the transmission belt 44, the driven pulley rotates in the reverse direction. Finally, the lifting plate 9 moves upward under the action of the two screws 41, and drives the first limiting plate 7 and the impact head 6 to rise through the first inclined block 101 on the fastening component 10, thus saving the process of manually lifting the impact piece and reducing the labor intensity of manual work.

[0025] In order to facilitate manual observation of the lifting height of the impact piece, a scale 8 is provided on the guide cylinder 5. At the same time, in order to facilitate the connection between the contact snap assembly 10 and the first limit plate 7, an unlocking assembly 11 is slidably provided on the guide cylinder 5, and the unlocking assembly 11 includes a second limit plate 111 slidably provided in the limit groove 51, and the second limit plate 111 is sleeved with a connecting ring 112 on the guide cylinder 5, and the connecting ring 112 is slidably provided with the guide cylinder 5. A first bolt 113 is threadedly provided on the connecting ring 112, and the connecting ring 112 can be fixed in the guide cylinder 5 by rotating the first bolt 113. A second inclined block 114 cooperating with the first inclined block 101 is also provided at the bottom end of the second limit plate 111. A groove 71 for the second inclined block 114 to pass through is opened at the position corresponding to the second inclined block 114 on the first limit plate 7. Specifically, according to the use requirements, the connecting ring 112 is slid to an appropriate position on the guide cylinder 5, and then the first bolt 113 is rotated, and the head of the first bolt 113 contacts the outer wall of the guide cylinder 5 to increase the friction force, and the connecting ring 112 is fixed on the guide cylinder 5. When the buckle assembly 10 drives the first limit plate 7 to rise until the second inclined block 114 passes through the groove 71 of the first limit plate 7, it continues to rise, and then the inclined surface of the second inclined block 114 will push the first inclined block 101, so that the first inclined block 101 moves outward on the lifting plate 9 until the first inclined block 101 releases the contact with the first limit plate 7, and then the first limit plate 7 and the impact head 6 will fall with their own weight to complete the impact on the building material. When the lifting plate 9 descends again, the first inclined block 101 will break away from the contact with the second inclined block 114, and move to the initial position under the action of the first spring 104, so as to facilitate the next operation of the unlocking assembly 11.

[0026] As another preferred embodiment, a slide plate 12 is slidably provided on the base 1, and a clamping assembly for fixing the building material is provided on the slide plate 12. The building material can be fixed by the clamping assembly to prevent the building material from falling after being impacted by the impact piece, thereby affecting the detection result. A second bolt 17 for fixing the position on the base 1 is also threadedly connected on the slide plate 12. It should be noted that in order to facilitate the operation of the first bolt 113 and the second bolt 17, a handle 18 is provided on the first bolt 113 and the second bolt 17.

[0027] like Figure 1As shown in the figure, the clamping assembly includes a second chute 121 formed in the sliding plate 12. A clamping plate 14 is slidably disposed in the second chute 121, and a second spring 15 is disposed in the second chute 121. The second spring 15 is located between the second chute 121 and the clamping plate 14. A baffle 13 that cooperates with the clamping plate 14 is further provided at one end of the sliding plate 12. When fixing building materials, the clamping plate 14 can be pulled, and the clamping plate 14 compresses the second spring 15. When the distance between the clamping plate 14 and the baffle 13 is suitable for clamping the test material, the building material is placed between the clamping plate 14 and the baffle 13, and then the clamping plate 14 is released. The spring pushes the clamping plate 14 to move towards the position of the baffle 13, completing the clamping and fixing of the building material by the clamping plate 14 and the baffle 13. To facilitate the impact test on different positions of the building material, the lateral position of the test material on the clamping assembly can be adjusted, and at the same time, the position of the impact point of the clamping material can be determined by adjusting the position of the slider on the base 1.

[0028] To prevent the second spring 15 from being excessively bent when compressed, a second guide post 16 is provided in the second chute 121, and the second guide post passes through the clamping plate 14 and is slidably disposed thereon. The second spring 15 is sleeved on the second guide post 16.

[0029] Usage method: According to actual usage requirements, first move the connecting ring 112 to an appropriate height on the guide cylinder 5 and use the first bolt 113 to fix its position on the guide cylinder 5. Then pull the clamping plate 14 apart, place the building material between the clamping plate 14 and the baffle 13, and then release the clamping plate 14. The second spring 15 pushes the clamping plate 14 to clamp and fix the building material. Then, the motor 42 in the lifting device 4 is activated, causing the lifting plate 9 threadedly connected to the screw rod 41 in the lifting device 4 to descend, and under the action of the fastening assembly 10 on the lifting plate 9, it is connected to the first limiting plate 7 of the impact member. After connection, the motor 42 of the lifting device 4 rotates in the reverse direction, causing the lifting plate 9 to move upward on the lifting device 4, and at the same time driving the impact member to move upward through the fastening assembly 10. After the impact member moves to an appropriate position, the unlocking assembly 11 cooperates with the fastening assembly 10 to release the connection between the fastening assembly 10 and the impact member, causing the impact member to fall to complete the impact test on the building material.
