Description

Technical Field

[0001] The utility model belongs to the technical field of drop hammer impact, and particularly relates to a drop hammer impact testing machine for sports equipment. Background Art

[0002] Sports equipment refers to the general term for various instruments, equipment, and supplies used in competitive sports competitions and fitness exercises. Sports equipment and sports are interdependent and promote each other. The popularization of sports and the diversification of sports events have developed the types, specifications, etc. of sports equipment. Most sports equipment originated from labor tools and combat weapons. For example, javelins and bows and arrows were both tools for ancient humans to hunt and weapons for ancient soldiers, and later evolved into equipment for modern throwing and archery sports. After the production of sports equipment, if it is not subjected to impact testing, it may cause damage during subsequent use.

[0003] The existing sports equipment impact testing devices have simple structures, and most of them are fixed and cannot move positions. They can only conduct impact tests on one point of the equipment. Therefore, it is necessary to manually change the position of the equipment for testing. However, for large and heavy equipment, it is relatively inconvenient to move, and the testing efficiency is low. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a drop hammer impact testing machine for sports equipment, and the technical scheme adopted is as follows:

[0005] A drop hammer impact testing machine for sports equipment includes a base. A pressure sensor is installed above the base. A test bench is provided above the pressure sensor. A support plate is installed above the base. A baffle is movably connected to one side of the support plate through a guide rod. A support frame is provided on one side of the base. A crank is installed on the support frame. The crank is fixedly connected to the support frame through a pin. A wire winding wheel is installed on the crank. A traction rope is fixedly wound on the wire winding wheel. An activity frame is provided above the support plate. The activity frame is movably connected to a chute opened on the support plate. An activity groove is opened above the activity frame. A first guide wheel is provided in the activity groove. A second guide wheel is provided on one side of the activity frame. The other end of the traction rope is fixedly connected to a hammer head through the second guide wheel and the first guide wheel respectively.

[0006] Further, a display screen is provided on one side of the pressure sensor to detect the pressure received by the sports equipment during the impact test.

[0007] Further, the activity frame and the support frame are fixedly connected through a connecting rod, and the connecting rod is in a "]" structure, which can keep the activity frame and the support frame always on the same horizontal plane, reduce the friction generated when the traction rope slides, and is beneficial to the rapid falling of the hammer head.

[0008] Furthermore, a groove for the sliding of the support frame is provided on one side of the support plate, facilitating the horizontal movement of the support frame.

[0009] Furthermore, the movable frame is movably connected to the support plate through a fixing bolt. After adjusting the movable frame to a suitable position, tighten the fixing bolt to prevent the offset of the movable frame during the falling process of the hammer head, which may affect the test results.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. In the utility model, the first guide wheel and the movable frame are designed. The first guide wheel moves in the movable groove, and the movable frame moves in the sliding groove, facilitating the change of the position of the hammer head, enabling the hammer head to perform impact tests on multiple points of sports equipment, making the test results more accurate, saving time, and improving the test efficiency.

[0012] 2. In the utility model, a baffle is installed on one side of the support plate. During the impact test, close the baffle, which can block the splashing of fragments caused by the damage to the equipment during the impact test, play a good protective role, and protect the safety of the staff.

[0019] As shown in the attachedFigures 1-3 as shown

[0020] A drop hammer impact testing machine for sports equipment, comprising a base 1, on which a support plate 2 is installed. Above the support plate 2, there is a movable frame 3. A chute 201 is opened above the support plate 2. The movable frame 3 is movably connected to the chute 201 through a fixing bolt 302. On one side of the movable frame 3, a second guide wheel 5 is installed. An activity slot 301 is opened above the movable frame 3. A first guide wheel 4 is movably connected in the activity slot 301 through a bolt.

[0021] A pressure sensor 14 is installed at the middle position of the base 1. On one side of the pressure sensor 14, there is a display screen for displaying pressure. Above the pressure sensor 14, a test bench 11 is fixed. On one side of the support plate 2, a baffle 10 is movably connected through a guide rod 12.

[0022] A support frame 9 is installed on one side of the base 1. The support frame 9 is fixedly connected to the movable frame 3 through a connecting rod 15. A crank 8 is installed on the support frame 9. The crank 8 is fixed to the support frame 9 through a pin 901. A winding wheel 7 is installed on the crank 8. A traction rope 6 is wound around the winding wheel 7. One end of the traction rope 6 is fixed to the crank 8, and the other end passes through the second guide wheel 5 and the first guide wheel 4 respectively, and then passes through the activity slot 301 and is fixedly connected to the hammer head 13.

[0023] The working process is as follows: Open the baffle 10, place the sports equipment on the test bench 11, close the baffle 10, move the movable frame 3 to slide in the chute 201, and then fix it through the fixing bolt 302. The movable frame 3 drives the support frame 9 to move simultaneously through the connecting rod 15, so that the movable frame 3 and the support frame 9 are always on the same horizontal plane, which can ensure the smooth sliding of the traction rope 6;

[0024] Move the first guide wheel 4 to slide in the activity slot 301 to change the position of the hammer head 13, and then fix the first guide wheel 4 through a bolt. Changing the positions of the movable frame 3 and the first guide wheel 4 to change the position of the hammer head 13 can facilitate the impact test on each position of the sports equipment and enhance the reliability of the data;

[0025] Pull out the pin 901, change the distance between the hammer head 13 and the sports equipment by rotating the crank 8. After adjustment, loosen the crank 8. The hammer head 13 falls downward under the action of gravity and impacts the sports equipment. The pressure sensor 14 tests the pressure received by the sports equipment and displays it on the display screen. The baffle 10 can block the fragments generated by the impact. Rotate the crank 8 to wind the traction rope 6 around the winding wheel 7, and the hammer head 13 rises accordingly. Then adjust the positions of the movable frame 3 and the first guide wheel 4, and drop the hammer head 13 again for the impact test, repeating the process until each position of the sports equipment is tested.

[0026] Any technical solution using the technical solution of the present utility model, or any technical solution designed by those skilled in the art inspired by the technical solution of the present utility model and achieving the above technical effects shall fall within the protection scope of the present utility model.
