DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0017] It should be noted that the orientation concepts of "left", "right", "up", "down", "front", "back", "inside" and "outside" in the following solutions are all relative directions, and will not be listed one by one here.

[0018] A door impact test device, refer to Figure 1 and Figure 2, including a frame 1. Triangular support parts 7 are arranged on both sides of the rear end of the frame 1 to support the frame 1 so that the frame 1 is arranged vertically. A vertically extending support rod 6 is arranged at the center of the frame 1. For those skilled in the art, two, three, four, etc. support rods 6 can be arranged between the frames 1, so that three, four, five, etc. door products can be fixed at the same time, and users can set it according to actual needs.

[0019] A plurality of fixing members 2 for fixing the door product to the frame 1 are arranged on both sides of the frame 1 and the support rod 6. A plurality of threaded through holes 8 are evenly opened in a square shape on both sides of the frame 1 and along the extension of the support rod 6. The fixing member 2 includes a screw rod 9 that is threadedly rotated to penetrate the threaded through hole 8. A first rotating disk 11 is arranged at one end of the screw rod 9 for easy rotation thereof, and a pressing plate 10 is arranged at the other end. By adjusting the position of the pressing plate 10, the door panel is firmly fixed and tightly attached to the frame 1.

[0020] A rotating rod 3 is rotatably provided at one end of the frame 1. A rope 4 is fixedly sleeved on the rotating rod 3, and a heavy hammer 5 is connected to the rope 4. When the impact resistance of the door product needs to be tested, the heavy hammer 5 only needs to be rotated to a certain height, and the heavy hammer 5 falls down to hit the door product under its own weight. When the door product is damaged, the change in gravitational potential energy is obtained by recording the lifting height and weight of the heavy hammer 5, and the change in gravitational potential energy is the impact resistance of the door product.

[0021] As a further improvement of the present invention, it can be further extended according to the above cases to provide a variety of new embodiments.

[0022] As a second embodiment of the present invention, based on Embodiment 1, Figure 3 and Figure 4 , a first sprocket 12 is arranged at the end of the rotating rod 3. A connecting rod 15 is rotatably arranged on the side wall of one side of the frame body 1. A second sprocket 13 is rotatably arranged on the connecting rod 15. A worm wheel 16 is arranged at the end of the connecting rod 15. The first sprocket 12 and the second sprocket 13 are connected by a chain 14. The radius of the second sprocket 13 is much smaller than the radius of the first sprocket 12. A worm 17 is meshed on one side of the worm wheel 16. The worm 17 is fixedly sleeved on the transmission rod 18. A second turntable 20 is arranged at the end of the transmission rod 18 for facilitating its rotation. For those skilled in the art, a motor can be used to drive the transmission rod 18 to rotate, and in real life, it is more common to use a motor to drive the transmission rod 18 to rotate. A support seat is arranged on the frame body 1, and the transmission rod 18 is rotatably connected to the support seat. A connecting piece 17 that is detachably connected to the second sprocket 13 is slidably sleeved on the transmission rod 18. The detachable connection method is that a square slot is opened on the right side of the second sprocket 13, and the connecting member 17 includes a sliding part 18 slidably mounted on the connecting rod 15, and a clamping part 19 is provided at the right end of the sliding part 18, which matches the shape and size of the square slot and can be detachably clamped with the square slot.

[0023] When it is necessary to lift the weight 5, the connecting member 17 is engaged with the second sprocket 13. The transmission rod 18 is rotated, so that the weight 5 swings and is lifted until the set height. In this way, the height of the weight 5 is lifted very precisely. Due to the self-locking performance of the worm gear 16 and the worm 17, the rotating rod 3 will not rotate due to the self-weight of the weight 5 at this time. When it is necessary for the weight 5 to fall and impact the door product, only the engagement between the connecting member 17 and the second sprocket 13 needs to be released. At this time, the weight 5 will fall under its own weight and impact the door product.

[0024] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above description or the technology or knowledge in the relevant field. And the changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
