Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following specific embodiments, and it should be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention.

Referring to fig. 1-3, a damping device for electromechanical devices comprises two opposite vertical plates 1, a box body 2 for an automatic transfer switch is installed between the two vertical plates 1, side plates 3 are fixed on two sides of the box body 2, the top and bottom of each side plate 3 are respectively and fixedly connected with a plurality of positioning rods 4 penetrating through the vertical plate 1, a plurality of limiting shafts 5 abutted against the vertical plate 1 are vertically fixed on the side plates 3, screw rods 6 penetrating through the vertical plates 1 are fixed at the outer ends of the limiting shafts 5, and the rod diameters of the screw rods 6 are smaller than the shaft diameters of the limiting shafts 5; the spring 7 that is located 5 both sides of spacing axle is fixed with on the curb plate 3, and spring 7 other end fixed connection clamp plate 8 has a depression bar 9 that articulates on the clamp plate 8, and the depression bar 9 other end articulates there is slider 10, and slider 10 sliding connection is on the lateral wall of riser 1.

In this embodiment, the vertical plate 1 is provided with a plurality of sliding grooves 11, and the sliding block 10 is slidably connected in the sliding grooves 11.

In the embodiment, a bottom plate 14 which is positioned below the box body 2 and is not in contact with the box body is fixedly connected between the two vertical plates 1, and a top plate 15 which is positioned above the box body 2 and is not in contact with the box body is fixedly connected between the two vertical plates 1; the bottom plate 14 is fixedly connected to the bottom of the side plate 3, and the top plate 15 is fixedly mounted on the top of the side plate 3.

In this embodiment, there are four sliding blocks 10 correspondingly installed on one limiting shaft 5, and the sliding grooves 11 corresponding to the four sliding blocks 10 are distributed in a cross shape.

In this embodiment, a self-locking nut 12 is fixedly connected to the screw 6 and abuts against the vertical plate 1.

In this embodiment, the positioning rod 4 is provided with a threaded section, and a fixing nut 13 abutting against the vertical plate 1 is fixed to the threaded section.

The working principle is as follows: when automatic change over switch began work, the slight displacement of left right direction can take place for box 2, and when external disturbance, the displacement also can appear for box 2, mechanical connection structure originally, on box 2 directly rancour to riser 1, collide with riser 1 the utility model discloses an in the picture, the slight striking that embodies between spacing axle 5 and riser 1 promotes, this is because assembly error and mechanical loss lead to, and the pine takes off appears taking off even from lock nut 12, leads to 5 vibration striking ranges of spacing axle to increase, consequently needs the stability of periodic maintenance mounting structure.

However, in a maintenance period, the impact vibration can affect the contact of the change-over switch, so that the change-over is unstable; therefore, the utility model discloses in set up corresponding structure, firstly, box 2 is at the slight displacement of left and right sides orientation, spring 7 can take place deformation this moment, press and move or stimulate clamp plate 8 to remove, thereby drive depression bar 9 and take place to rotate, slider 10 slides in spout 11, spout 11 plays a limiting displacement to slider 10 slip orientation, because the length of spout 11 is limited, when contacting the boundary, this will resist box 2 and continue to move towards the original orientation, set up like this and can compensate the problem that only has spring 7 constantly to make a round trip to vibrate, because the friction that receives in the gliding process of slider 10 can weaken the vibration, let spring 7 play abundant cushioning effect; secondly, the box body 2 is slightly displaced in the up-down direction because the bottom plate 14 and the top plate 15 do not directly contact the box body 2, when the impact occurs, the shock reaching the box body 2 is relieved, the shock appears on the side plates 3, and the buffering shock can be relieved by the above method.
