[0028] like Figure 1 and Figure 2 As shown, a vibration and shock test fixture suitable for various sizes of mainframes includes a frame 1, which is used to mount the various components of the test fixture, facilitating assembly and use of the entire test fixture. Multiple reinforcement rods 12 are evenly distributed across the top of the frame 1 to enhance the strength of the entire test fixture. A pressure plate 2 is located inside the frame 1 to facilitate applying pressure to the mainframe and facilitating vibration and shock testing of the mainframe. Lifting rods 4 are located on either side of the pressure plate 2, with their bottom ends extending through the pressure plate 2 and connected to it. These rods 4 are used to raise the pressure plate 2 to a desired height. The tops of the lifting rods 4 are connected to the reinforcement rods 12 on either side of the frame 1. This structure stabilizes the lifting rods 4 and facilitates their upward and downward movement. Multiple pressure rods 3 are located on each reinforcement rod 12 at the top of the frame 1. These pressure rods 3 are evenly distributed across the corresponding reinforcement rods 12, with their bottom ends pressing against the top surface of the pressure plate 2. These pressure rods 3 facilitate applying pressure to the pressure plate 2, thereby facilitating the pressure plate 2's application of pressure to the mainframe.

[0029] Working principle: When in use, it is necessary to rotate the pressure rod 3 to the highest position, and then rotate the lifting rod 4 so that the lifting rod 4 lifts the pressure plate 2 to the appropriate height, and put the host to be tested in the center position of the frame 1, and then rotate the lifting rod 4 so that the lifting rod 4 drives the pressure plate 2 to press down, and makes the bottom surface of the pressure plate 2 fit on the host, and then rotate the pressure rod 3 until the bottom end of the pressure rod 3 presses on the pressure plate 2 and applies uniform force, so that the pressure plate 2 compacts the host. Compared with the prior art, the present application has a pressure plate 2 on the upper inner side of the frame 1, and the height of the pressure plate 2 can be adjusted by the lifting rod 4; at the same time, the pressure rod 3 is used to apply pressure to the pressure plate 2, so that the pressure plate 2 can evenly apply pressure to the test host, ensuring the uniformity of the force on the test host; in this way, hosts of various sizes can be placed inside the frame 1 for pressure application, and the uniformity of the force on them is ensured, which greatly facilitates the vibration and impact testing of electronic equipment of different sizes, and the operation of the entire tooling is simple and convenient.

[0030] Example 2

[0031] like Figure 1 and Figure 2 As shown, a vibration and shock test fixture suitable for various sizes of mainframes includes a frame 1, which is used to mount the various components of the test fixture, facilitating assembly and use of the entire test fixture.

A pressure plate 2 is located inside the frame 1 to facilitate applying pressure to the mainframe and facilitating vibration and shock testing of the mainframe. Lifting rods 4 are located on either side of the pressure plate 2, with their bottom ends extending through the pressure plate 2 and connected to it. These rods 4 are used to raise the pressure plate 2 to a desired height. The tops of the lifting rods 4 are connected to the reinforcement rods 12 on either side of the frame 1. This structure stabilizes the lifting rods 4 and facilitates their upward and downward movement. Multiple pressure rods 3 are located on each reinforcement rod 12 at the top of the frame 1.
