Description

Technical Field

[0001] This utility model relates to the field of wooden door technology, specifically to a wooden door sandbag impact testing device. Background Technology

[0002] Before leaving the factory, wooden doors undergo random impact testing to ensure product quality and safety meet requirements. Impact testing effectively assesses the structural strength and impact resistance of wooden doors, simulating sudden collisions that doors may encounter during transportation, installation, or daily use. This prevents problems such as door frame deformation, hardware detachment, or surface damage caused by external impacts, ensuring user safety. Simultaneously, the test verifies the durability of the wooden doors, repeatedly testing the stability of key components such as door joints and lock fixing points to ensure the product maintains normal function over long-term use, reducing maintenance costs. Furthermore, impact testing is a mandatory requirement of industry standards and safety certifications, complying with building codes and fire regulations, avoiding legal risks arising from substandard products. This impact testing process can expose design flaws or material shortcomings, driving process optimization. Previously, the workshop used cutting the wood panels used for wooden doors into sheets for simulated testing; however, sheets cannot fully represent the condition of wooden doors under real impact, and the test results are subject to further discussion.

[0019] like Figure 1-4 As shown, a wooden door sandbag impact testing device includes a frame 1, a sandbag 3, a traction belt 2, a drive mechanism, a pressing mechanism, and a clamping mechanism. The frame 1 is a three-dimensional rectangular structure. The drive mechanism is fixedly connected to the bottom left side of the frame 1, the pressing mechanism is fixedly connected to the top left side of the frame 1, and the clamping mechanism is fixedly connected to the right side of the frame 1. The right end of the traction belt 2 is fixedly connected to the top right side of the frame 1, and the left end of the traction belt 2 passes through the pressing mechanism and is connected to the drive mechanism. The sandbag 3 is fixedly suspended on the traction belt 2 on the right side of the pressing mechanism, and the sandbag 3 can swing into the clamping mechanism. The wooden door to be tested is installed in the clamping mechanism and subjected to impact testing. The drive mechanism pulls the traction belt 2 downwards, causing the traction belt 2 located on the right side of the clamping mechanism to be nearly straight, thereby raising the position of the sandbag 3. When the sandbag 3 rises to its highest point, the clamping mechanism presses down the traction belt 2. Then, the drive mechanism resets upwards, storing a section of the traction belt 2 between the clamping mechanism and the drive mechanism. When the drive mechanism rises to its highest point, the traction belt 2 can be released through the clamping mechanism. Under the action of the sandbag 3's gravity, the sandbag 3 and the traction belt 2 swing around the top right side of the frame 1 along an arc-shaped trajectory and impact the wooden door. This is repeated a certain number of times, and the wooden door impact test can be judged by visual observation to determine whether it is qualified.

[0020] In the above embodiment, the driving mechanism includes a cylinder 5 and a guide wheel 6. The cylinder 5 is fixedly connected to the bottom left side of the frame 1, with its output end facing upwards and connected to both ends of the guide wheel 6. The left end of the traction belt 2 passes around the bottom of the guide wheel 6 and is fixedly connected to the top left side of the frame 1. When the cylinder 5 retracts downwards and pulls the traction belt 2, the guide wheel 6 rolls, causing the traction belt 2 to be pulled smoothly. The pressing mechanism includes a pressure frame 7, an electric push rod 8, and a pressure plate 9. The pressure frame 7 is fixedly connected to the top left side of the frame 1. The electric push rod 8 is installed in the pressure frame 7, and its output end is connected to the pressure plate 9. An opening and closing channel 10 is formed between the pressure plate 9 and the pressure frame 7, through which the traction belt 2 passes. By controlling the electric push rod 8, the pressure plate 9 can open or close the opening and closing channel 10 to allow the traction belt 2 to pass through or be pressed.

[0021] The clamping mechanism includes clamping plates 11 and limiting plates 12. There are two clamping plates 11, which are connected vertically to the right side of the frame 1. The adjacent sides of the clamping plates 11 are provided with grooves 1101. The limiting plates 12 are fixed to the side of the clamping plates 11 where the grooves 1101 are located by screws 13. A clamping groove is formed between the grooves 1101 of the two clamping plates 11. The wooden door can be inserted into the clamping groove from the outside and limited and fixed by the limiting plates 12 to resist the impact force brought by the impact test. The side of the clamping plate 11 is provided with a sliding groove 1102, which communicates with the grooves 1101. The limiting plates 12 are slidably connected to the sliding groove 1102. The middle of the limiting plates 12 is provided with an adjustment groove 1201. The screws 13 pass through the adjustment groove 1201 and fix the limiting plates 12 to the sliding groove 1102. After slightly loosening the screws 13, the limiting plates 12 can be adjusted laterally so that the wooden door can get or lose the limiting effect of side abutment, thereby realizing the quick loading and unloading of the wooden door. The upper and lower ends of the clamping plate 11 are slidably connected to the frame 1, and the width of the clamping groove can be adjusted to adapt to wooden doors of different sizes and widths.

[0022] A fixed pulley 4 is suspended from the top of the frame 1, and the traction belt 2 can be hung on the fixed pulley 4 to further improve the smoothness of the traction belt 2 when pulling. A bracket 14 is provided on the side of the frame 1, which can be connected and fixed to the wall to ensure the stability of the entire frame 1 during the impact test.

[0023] In addition, this device can be equipped with an external control cabinet, which allows manual control of cylinder 5 and electric push rod 8 via touch screen, or timed and delayed control via PLC, to achieve fully automated wooden door impact testing.

[0024] Description of the working principle of this utility model:

[0025] The wooden door is loaded into the groove between the two clamping plates 11 and fixed by the locking limit plate 12. The wooden door is shaken to confirm its stability. The cylinder 5 pulls the traction belt 2 downward to raise the sandbag 3 to the highest position. The pressure plate 9 presses down the traction belt 2. Then the cylinder 5 pushes upward. After the cylinder 5 rises to the highest position, the pressure plate 9 is released and the traction belt 2 is released. Under the action of the weight of the sandbag 3, the sandbag 3 and the traction belt 2 swing around the top right side of the frame 1 along an arc trajectory and hit the wooden door. The impact is repeated 50 times. The wooden door surface is visually observed for cracks, or the length and width of the cracks are measured. The test standard is then compared to determine whether the wooden door has passed the impact test.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
