The solution is to set a first fixed ring, a second fixed column, a connecting rod, a first fixed column and a slider, and connect the first fixed ring with the support frame. By setting a second spring and a rubber pad, the first fixed ring is used to drive the first connecting column to push the second fixed ring, and the elastic force of the spring is used to reduce the buffering force, thereby protecting the device.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model are described clearly and completely below. The embodiments of the utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figures 1 to 6The utility model provides a technical solution: a control device for an electromagnetic compatibility test device, including a detector body 1, a fixed block 5, a support plate 8, a first support frame 9, a second support frame 11 and an auxiliary shock absorption control component. The inner end surface of the detector body 1 is fixedly connected to the fixed block 5, the lower part of the upper end surface of the detector body 1 is fixedly connected to the support plate 8, and the side end surface of the support plate 8 is fixedly connected to the first support frame 9 and the second support frame 11; the auxiliary shock absorption control component includes an elastic washer 2, a connecting column 3, a rack 4, a slide rail 6, a stretching rod 7, a clamping block 10, a gear 12, an extension plate 13, a spring 14, a gear seat 15, a square block 16, a square groove 17, an arc-shaped limit block 18 and a slide groove 19, and the lower part of the elastic washer 2 is fixedly connected to the connecting The connecting column 3, the side end plane of the connecting column 3 is fixedly connected to the rack 4, the lower end surface of the slide rail 6 is fixedly connected to the fixed block 5, and the two sides of the upper end surface of the slide rail 6 are fixedly connected to the gear seat 15, the upper end surface of the gear seat 15 is fixedly connected to one end of the spring 14, and the other end of the spring 14 is fixedly connected to the extension plate 13, and the side end of the extension plate 13 is fixedly connected to the connecting column 3, the clamping block 10 is rotatably connected between the two groups of first support frames 9, the gear 12 is rotatably connected between the two groups of second support frames 11, the stretching rod 7 movably passes through the detector body 1 and the support plate 8, and is movably connected with the arc limit block 18, the square block 16 is fixedly connected to the side end surface of the stretching rod 7, the square groove 17 is penetrated and opened in the support plate 8 and the side end surface of the detector body 1, and the slide groove 19 is opened on the inner end surface of the first support frame 9.
[0024] Four groups of auxiliary shock-absorbing control components are symmetrically arranged at equal distances to ensure that the detector device lands smoothly.
[0025] The teeth in the rack 4 are bar-shaped and symmetrically provided with multiple groups. The rack 4 is adapted to the clamping gear 12, and the tooth shape of the gear 12 has an arc-shaped inclination angle. The gear 12 is adapted to the corresponding clamping block 10, which ensures that the rack 4 has stability during movement, and at the same time ensures that the rotational movement of the gear 12 can be limited by the clamping block 10; when the arc-shaped limit block 18 moves to the front end of the slide groove 19, the arc-shaped limit block 18 contacts the lower end surface of the clamping block 10, and the rotational movement direction of the clamping block 10 can only move upward, and cannot move downward. The gear 12 allows the connecting column 3 to only move downward, and its movement path is the direction of the internal slide groove of the slide rail 6. The slide rail 6 is adapted to be plugged into the connecting column 3, ensuring that when the arc-shaped limit block 18 contacts the clamping block 10, the device can only move downward, and the self-locking function can be realized during the downward movement, thereby avoiding the situation that it shakes. At the same time, if it is necessary to release the function of only being able to descend, it is only necessary to prevent the arc-shaped limit block 18 from contacting the clamping block 10.
[0026] A square groove is provided inside the detector body 1, and the square groove is adapted to fit the card-engaging square block 16. A convex block in the same direction as the square block 16 is provided at the outer end of the stretching rod 7. The square block 16 is adapted to fit the sliding connection square groove 17. The arc-shaped limit block 18 is adapted to fit the sliding connection slide groove 19, so that the distance between the arc-shaped limit block 18 and the card-engaging block 10 can be determined by whether the stretching rod 7 is plugged in and fixed. The slide groove is provided to ensure the smoothness of the overall movement process.
[0027] The utility model is a control device for an electromagnetic compatibility test device. In actual use, when the electromagnetic compatibility test device needs to be placed, firstly, the four groups of stretching rods 7 at the side ends of the detector body 1 need to be rotated, the protrusions at the outermost ends of the stretching rods 7 are aligned with the square grooves 17, and are squeezed inwardly. At this time, the square blocks 16 will move inside the square grooves 17, and the arc-shaped limit blocks 18 will move in the slide grooves 19. When the arc-shaped limit blocks 18 move to the front end, the arc-shaped limit blocks 18 abut against the clamping blocks 10, so that the movement direction of the clamping blocks 10 is restricted, and the stretching rods 7 are rotated. Rotate it from the original horizontal direction to the vertical direction, the square block 16 connected to the stretching rod 7 will be smoothly snapped into the square groove set inside the detector body 1, so as to realize the limit fixation of the stretching rod 7. When the four groups of stretching rods 7 are all set, place the electromagnetic compatibility test device downward. At this time, the device will squeeze the elastic gasket 2 under its own gravity, and make the connecting column 3 move inward, and the rack 4 will fit the transmission gear 12. Because the gear 12 is plugged in by the snap-in block 10, and the snap-in block 10 is limited in the range of movement path, the rotation direction of the gear 12 can only allow the connecting column 3 to move inward. When the spring 14 enters the slide rail 6, the spring 14 is in a compressed state, and its own elastic force will become larger and larger, reducing the movement speed of the connecting column 3 until it stops. During the overall movement, the connecting column 3 will not move in the opposite direction. If the heights of the four sets of auxiliary shock absorbing control components are inconsistent, the test device can be directly squeezed downward to achieve a parallel state. When the test is completed, the restriction needs to be released, and the stretching rod 7 can be rotated again from the vertical direction of the protrusion to the horizontal direction, so that the square block 16 enters the square groove 17, and the stretching rod 7 is pulled outward to make the arc limit block 18 disengage. The spring 14 is compressed all the time to limit the clamping block 10. When the limit is released, its elastic force will make the connecting column 13 move upward. The overall design is simple in operation. It not only achieves a shock-absorbing effect on the test device when it is placed, but also protects the test device. After it is placed, its movement trajectory will only be downward, not upward. In the process of downward movement, it will also achieve self-locking, thereby avoiding the problem of shaking of the test device and avoiding the problem of accidentally touching the test device due to the external environment during the test, causing it to shake, thereby ensuring the accuracy of the test data.
