The three-dimensional rectangular support frame 1 is used to support the horizontal support rod 2 and the control screen connecting plate 3, that is, to fix the control screen being tested. The bottom of the three-dimensional rectangular support frame 1 is fixedly connected to the experimental table.
[0028] In this embodiment, if Figure 2 and 3 As shown, the three-dimensional rectangular support frame 1 includes an upper rectangular frame 11, a lower rectangular frame 12, and a vertical support rod 13 connected between the upper rectangular frame 11 and the lower rectangular frame 12. The vertical support rods 13 are fixed at the four corners of the upper rectangular frame 11 and the lower rectangular frame 12, so that the structure of the entire three-dimensional rectangular support frame 1 is stable, ensuring the smooth progress of the experiment and the accuracy of the experimental results. A plurality of laboratory table connection holes 15 are fixed along the length direction of the four sides of the lower rectangular frame 12. The laboratory table connection holes 15 are used to connect with the laboratory table. The three-dimensional rectangular support frame 1 can be connected with the laboratory table by bolts and nuts passing through the laboratory table connection holes 15 to achieve fixed connection between the three-dimensional rectangular support frame 1 and the laboratory table.
[0029] In an optional embodiment, the experimental table connection holes 15 on each side of the lower rectangular frame 12 are evenly distributed. The evenly distributed experimental table connection holes 15 make the force on the three-dimensional rectangular support frame 1 more uniform, thereby ensuring the accuracy of the experimental results.
[0030] In an optional embodiment, a reinforcing rod 14 arranged along a diagonal line is fixed inside the lower rectangular frame 12. Two reinforcing rods 14 are cross-fixed inside the lower rectangular frame 12, and the ends of the reinforcing rods 14 are respectively welded to the adjacent sides of the lower rectangular frame 12, thereby improving the structural strength and support strength of the three-dimensional rectangular support frame 1.
[0031] like Figure 1 As shown, two horizontal support rods 2 are arranged in parallel on the top of the three-dimensional rectangular support frame 1. Figure 1 The two horizontal struts 2 are placed longitudinally in the horizontal plane, and the distance between the two horizontal struts 2 is adjusted by sliding along two sides of the three-dimensional rectangular support frame 1. The two horizontal struts 2 slide laterally along the horizontal sides of the upper rectangular frame 11 to adjust the distance, and are locked and fixed with the three-dimensional rectangular support frame 1 by the first locking mechanism 4; after the distance adjustment is completed, the horizontal struts 2 are locked with the upper rectangular frame 11 by the first locking mechanism 4, and the horizontal struts 2 no longer slide.
[0032] like Figure 1 As shown, two control screen connecting plates 3 are arranged on the top of each horizontal support rod 2. The control screen connecting plates 3 are used to be fixedly connected to the control screen. The control screen is fixed above the control screen connecting plates 3, and the four control screen connecting plates 3 are arranged in a rectangular shape; the two control screen connecting plates 3 on each horizontal support rod 2 are used to adjust the distance between the two control screen connecting plates 3 by sliding along the horizontal support rod 2, and the control screen connecting plates 3 are locked and fixed to the horizontal support rod 2 by the second locking mechanism 5, and the second locking mechanism 5 is detachably connected to the control screen connecting plates 3 and the horizontal support rod 2. After the distance adjustment is completed, the position of the control screen connecting plates 3 is fixed by the second locking mechanism 5 and no longer slides; the lateral distance between the control screen connecting plates 3 is adjusted by adjusting the distance between the horizontal support rods 2, and the longitudinal distance between the control screen connecting plates 3 is adjusted by sliding the control screen connecting plates 3 along the longitudinal direction of the horizontal support rod 2, so that control screens with different installation interface distances can be matched.
[0033] like Figure 1 As shown, a control panel connection hole 31 is provided at the center of the control panel connection plate 3, and a stud is provided below the bottom shock absorber of the control panel. The stud passes through the control panel connection hole 31 and is connected with a nut, so that the control panel and the control panel connection plate 3 can be fixedly connected. Since the second locking mechanism 5 is detachably connected to the control panel connection plate 3 and the horizontal support rod 2, the control panel connection plate 3 can be directly replaced for control panels with different installation interface sizes, so that the experimental tooling can be applicable to control panels with different installation interface sizes.
[0034] In this embodiment, if Figure 1 and 4As shown, each end of the horizontal support rod 2 is locked and fixed with the edge of the three-dimensional rectangular support frame 1 through a first locking mechanism 4, and the first locking mechanism 4 includes a first locking rod 41, a first locking plate 42, a first locking nut 43, a second locking rod 44 and a first clamping mechanism 45.

The upper half of a locking rod 41 is a threaded section, the first locking plate 42 is perpendicular to the first locking rod 41 and is sleeved on the threaded section of the first locking rod 41, the first locking plate 42 is placed on the top of the horizontal support rod 2, and the first locking nut 43 is threadedly connected to the threaded section above the first locking plate 42 of the first locking rod 41. The first locking nut 43 locks the horizontal support rod 2 and the edge of the three-dimensional rectangular support frame 1 in the space surrounded by the first locking rod 41, the first locking plate 42 and the second locking rod 44. The first locking plate 42 and the first locking plate 42 are adjusted by screwing the first locking nut 43 downward. The vertical distance between the two locking rods 44 presses the first locking plate 42 downward in the direction of the second locking rod 44, and then presses the horizontal support rod 2 and the edge of the upper rectangular frame 11 between the first locking plate 42 and the second locking rod 44. The first locking plate 42, the second locking rod 44 and the first locking nut 43 cooperate to apply a locking force in the vertical direction; the first clamping mechanism 45 is fixedly connected to the first locking rod 41 to clamp the edge of the three-dimensional rectangular support frame 1. The first clamping mechanism 45 applies a horizontal force to firmly fix the horizontal support rod 2 on the three-dimensional rectangular support frame 1.
[0035] In this embodiment, the first locking nut 43 is a butterfly nut, which is easy to screw. Optionally, a hexagonal nut is provided on the side of the first locking plate 42 away from the first locking nut 43, that is, a hexagonal nut is provided below the first locking plate 42, and the hexagonal nut is threadedly connected to the threaded section of the first locking rod 41, so that the two ends of the first locking plate 42 are balanced and fixed more firmly, avoiding the loosening of the first locking nut 43 during the vibration environment screening experiment, which causes the first locking plate 42 to loosen and cause inaccurate experimental data.
[0036] In this embodiment, if Figure 1 and 4As shown, the first clamping mechanism 45 includes a first slider 451, a first spring 452, a first rotating shaft 453 and a first eccentric pressure rod 454.

The first eccentric pressing rod 454 clamps the edge of the three-dimensional rectangular support frame 1 between the first slider 451 and the first locking rod 41. The first eccentric pressure rod 454 is fixed to the middle part of the first rotating shaft 453, and the protruding part of the first eccentric pressure rod 454 is close to the second locking rod 44. The end of the first sliding block 451 away from the second locking rod 44 and close to the first eccentric pressure rod 454 is provided with an L-shaped groove. The eccentric structure of the first eccentric pressure rod 454 corresponds to the L-shaped groove. When the edge of the three-dimensional rectangular support frame 1 is not clamped, the first spring 452 is in a natural state. When the edge of the three-dimensional rectangular support frame 1 needs to be clamped, it moves to the side close to the second locking rod 44. The rod of the first eccentric pressure rod 454 is pressed, and the protruding part of the eccentric structure at the other end of the first eccentric pressure rod 454 rotates toward the first slider 451 and pushes the first slider 451 to slide toward the first spring 452. At the same time, the first spring 452 is compressed, and after the protruding part of the first eccentric pressure rod 454 is stuck in the L-shaped groove, if no external force is applied manually, the first eccentric pressure rod 454 will no longer rotate, and the edge of the three-dimensional rectangular support frame 1 will be firmly clamped between the first locking rod 41 and the first slider 451. When releasing the edge of the three-dimensional rectangular support frame 1, the rod of the first eccentric pressure rod 454 can be pulled in the opposite direction, and the restoring elastic force of the first spring 452 pushes the first slider 451 in the opposite direction to release the edge of the three-dimensional rectangular support frame 1.
[0037] In order to make the fixation of the horizontal support rod 2 more secure, in the present embodiment, the top surface of the horizontal support rod 2 is fixedly connected to the bottom surface of the first locking plate 42, preferably by welding, so that the horizontal support rod 2 and the first locking plate 42 are fixed as a whole.
[0038] like Figure 1 and 5As shown, the second locking mechanism 5 includes a third locking rod 51, a fourth locking rod 52, a second locking nut 53 and a second clamping mechanism 54.
