[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 5 A high-efficiency hard disk test fixture comprises a test bench 1, a clamping mechanism 2 for clamping a hard disk is installed on the test bench 1, a support frame 3 is symmetrically fixedly installed on the test bench 1, a mounting plate 4 is fixedly installed on two support frames 3, a lifting block 5 is vertically slidably installed between the two mounting plates 4 through a sliding assembly, the sliding assembly comprises a plurality of slide rails 11 respectively and symmetrically fixedly installed on the two mounting plates 4 and two sliders 12 respectively and slidably sleeved on the plurality of slide rails 11, the lifting block 5 is fixedly connected to the two sliders 12, and an impact block 6 is fixedly installed on the lower end of the lifting block 5;

[0024] The clamping mechanism 2 can clamp and fix the hard disk placed on the test bench 1, and the slider 12 can slide vertically up and down on the slide rail 11, so that the lifting block 5 can be driven by the slider 12 to slide up and down between the two mounting plates 4;

[0025] A driving motor 7 is fixedly mounted on the test bench 1, a rotating disk 8 is fixedly sleeved on the output shaft of the driving motor 7, two blocking rods 9 are fixedly mounted on the rotating disk 8, a U-shaped rod 10 is fixedly mounted on the side of the lifting block 5, and both the two blocking rods 9 are in intermittent sliding contact with the U-shaped rod 10;

[0026] When the lifting block 5 moves to the highest point, the baffle 9 will separate from the U-shaped rod 10. At this time, under the action of the self-gravity of the lifting block 5, the impact block 6 will be driven to move vertically downward and impact the hard disk clamped on the test bench 1 to perform an impact test on it. By continuously rotating the rotating disk 8, the baffle 9 can be continuously driven to contact and then separate from the U-shaped rod 10, thereby continuously driving the impact block 6 to impact the hard disk, thereby realizing continuous impact test on the hard disk, and effectively improving the test efficiency.

[0027] A cavity is provided inside the lifting block 5, and a vertical pipe 13 connected to the cavity is fixedly installed on the upper end of the lifting block 5. Water can be injected into the cavity to increase the weight of the lifting block 5, thereby changing the impact force of the impact block 6 hitting the hard disk.

[0028] A water tank 14 is fixedly mounted on the two support frames 3 through a support block. The water tank 14 is filled with water. A water outlet pipe 15 communicating with the inside is fixedly connected to the bottom of the water tank 14. The outer diameter of the vertical pipe 13 is the same as the inner diameter of the water outlet pipe 15. A plugging assembly for blocking the water outlet pipe 15 is provided in the water tank 14. The plugging assembly includes two L-shaped rods 16 symmetrically fixedly mounted on the inner wall of the water tank 14, two spring rods 17 respectively fixedly mounted on the two L-shaped rods 16, and a blocking block 18 fixedly mounted on the lower ends of the two spring rods 17. A V-shaped top block 19 is fixedly mounted on the upper end of the vertical pipe 13. The top block 19 is located directly below the blocking block 18.

[0029] Under the action of the elastic force of the spring rod 17, the blocking block 18 contacts the upper end of the water outlet pipe 15, thereby blocking the water outlet pipe 15. When the lifting block 5 is about to rise to the uppermost end, the vertical pipe 13 will be inserted into the water outlet pipe 15, and the top block 19 will be driven to contact the blocking block 18, driving the blocking block 18 to move vertically upward, and the spring rod 17 is compressed. At this time, the blocking block 18 is separated from the upper end of the water outlet pipe 15, and the water in the water tank 14 will enter the cavity opened in the lifting block 5 through the vertical pipe 13, thereby changing the overall weight of the lifting block 5. When the lifting block 5 drives the impact block 6 to impact the hard disk, the impact force of each impact can be changed. When the impact is performed continuously, the impact force will continue to increase, so that the hard disk can be tested under different impact forces, ensuring that the impact resistance performance of the hard disk test is more accurate.

[0030] A sealing gasket is fixedly installed on the lower surface of the blocking block 18 . The sealing gasket is made of rubber and can prevent water in the water tank 14 from leaking out from between the blocking block 18 and the water outlet pipe 15 .

[0031] In the utility model, during the test, the rotating disk 8 is driven to rotate by the driving motor 7, and then the two baffle rods 9 are driven to rotate by the rotating disk 8. During the rotation, the baffle rod 9 will contact the U-shaped rod 10 and drive the lifting block 5 to move vertically upward. When the lifting block 5 moves to the highest point, the baffle rod 9 will separate from the U-shaped rod 10. At this time, under the action of the lifting block 5's own gravity, the impact block 6 is driven to impact the hard disk to perform an impact test on it. Through the continuous rotation of the rotating disk 8, the impact block 6 can be continuously driven to impact the hard disk, thereby realizing a continuous impact test on the hard disk, effectively improving the test efficiency.

[0032] In general, in view of the technical problem: the existing solid-state hard disk impact resistance test fixture cannot perform impact test continuously, and can only drive the impact block to perform impact test once, thereby reducing the efficiency of the test and failing to meet the use needs; adopting a technical solution: through the cooperation of the driving motor 7, the rotating disk 8, the baffle 9, the U-shaped rod 10, the lifting block 5, the sliding assembly and the impact block 6, the hard disk can be continuously impact tested; because the implementation process of the technical solution is: during the test, the rotating disk 8 is driven to rotate by the driving motor 7, and then the two baffles 9 are driven to rotate by the rotating disk 8. During the rotation, the baffle 9 will contact the U-shaped rod 10 and drive the lifting block 5 to move vertically upward. When the lifting block 5 moves to the highest point, the baffle 9 will separate from the U-shaped rod 10. At this time, under the action of the self-gravity of the lifting block 5, the impact block 6 is driven to impact the hard disk and perform an impact test on it. By continuously rotating the rotating disk 8, the impact block 6 can be continuously driven to impact the hard disk; so the technical problem can be solved, and the technical effect achieved is: to achieve continuous impact test on the hard disk and effectively improve the efficiency of the test.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
