When the right side at the switch board receives the striking, the left outer wall of interior box 4, the elastic sliding block 7 on the outer wall of back and the left internal face of outer box 1, slide rail 2 cooperation on the internal face of back, in order to realize moving up the guide effect on in-process left side and rear side to interior box 4, and the elastic sliding block 7 of the outer wall of the left side of interior box 4 and the slide rail 2 cooperation on the internal face of the left side of outer box 1, make interior box 4 remove the in-process that rises to the right, the left side of interior box 4 keeps ending all the time with the left side of outer box 1, can improve interior box 4 and move the stability of in-process to the right. And the transverse moving mechanism 5 on the rear outer wall surface of the inner box body 4 can ensure that the inner box body 4 can move rightwards when the front side of the power distribution cabinet is impacted.

Similarly, when the right side of switch board received the striking, interior box 4 can move left, and its analytic process refers to the condition that "the left side of switch board received the striking", and here is no longer repeated.

In some embodiments, as shown in fig. 3 and 4, the traverse mechanism 5 includes a guide rail 51, a guide rod 52, a traverse seat 53, and a first spring 54, the guide rail 51 is provided with a guide groove 51a, the guide rod 52 is parallel to the guide rail 51, the traverse seat 53 is provided with a moving block 53a, the moving block 53a is fitted in the guide groove 51a, the traverse seat 53 is provided with a through hole 53b, the through hole 53b is fitted with the guide rod 52, the first spring 54 is provided on two opposite sides of the traverse seat 53, a first spring housing 54 is provided on the guide rod 52, one end of the first spring 54 abuts against the traverse seat 53 and the other end abuts against an end of the guide rod 52, and the traverse seat 53 is connected to the elastic slider 7.

The working principle of the transverse moving mechanism 5 is as follows: taking the transverse moving mechanisms 5 on the left side and the right side as an example, when the front side of the power distribution cabinet is impacted, the inner box body 4 moves backwards under the action of inertia force, at the moment, in the transverse moving mechanisms 5 on the left side and the right side, the transverse moving seats 53 are matched with the guide grooves 51a through the moving blocks 53a and the guide rods 52 through the through holes 53b, and the transverse moving seats 53 move backwards along the guide rails 51 and the guide rods 52, so that the stability and the reliability of the inner box body 4 in the process of backwards moving are improved. And the first spring 54 at the rear side can be compressed in the process of moving the traversing seat 53 backwards, so that the first spring 54 can absorb a part of impact, and the safety is ensured. The cooperation of the front first spring 54 and the rear first spring 54 can ensure that the traverse seat 53 is centered in the initial state, which facilitates the centering of the inner box 4 in the outer box 1.

Similarly, when the left side or the right side of the power distribution cabinet is impacted, the analysis process is referred to the above, and is not repeated here.

In some embodiments, as shown in fig. 3 and 4, the elastic slider 7 includes a slider main body 71, a first roller 72, and a second spring 73, wherein a sliding column 71a is disposed on the slider main body 71, a sliding hole 53c is disposed on the traverse seat 53, the sliding column 71a fits in the sliding hole 53c, a limit block 71b is disposed on one end of the sliding column 71a close to the inner box 4, the first roller 72 is disposed on the other end of the sliding column 71a, a sliding rail groove 2a is disposed on the sliding rail 2, the first roller 72 fits in the sliding rail groove 2a, the second spring 73 is disposed on the other end of the sliding column 71a, one end of the second spring 73 is connected to the sliding column 71a, and the other end of the second spring 73 abuts against the traverse seat 53.

The working principle of the elastic sliding block 7 is as follows: when the inner case 4 is positioned in the outer case 1, the left, right, and rear second springs 73 are compressed. Taking the elastic sliding blocks 7 on the left and right sides as an example, when the power distribution cabinet is impacted leftwards, the inner box body 4 moves leftwards under the action of inertia force, in the elastic sliding block 7 on the left side, the transverse moving seat 53 on the left side is matched with the sliding column 71a through the sliding hole 53c, and moves leftwards on the sliding column 71a along with the inner box body 4, during which the second spring 73 continues to be compressed, and when the inner box body 4 moves upwards, the first roller 72 rolls along the sliding rail groove 2 a; in the right elastic slider 7, the right traverse seat 53 is engaged with the spool 71a through the slide hole 53c, and as the inner case 4 moves leftward on the spool 71a, the second spring 73 continues to be released and extended, and the first roller 72 rolls along the rail groove 2a when the inner case 4 moves upward. The limiting block 71b is used for limiting the sliding column 71a from separating from the sliding seat 53. The analysis process of the elastic slider 7 on the rear side is described above, and is not described in detail here.

And two first rollers 72 and two slide rail grooves 2a ensure that the guiding and supporting effects are improved, so that the movement of the inner box body 4 is more stable.

In some embodiments, as shown in fig. 2, 5, and 6, two lateral moving mechanisms 5 are disposed on each of the left outer wall surface, the right outer wall surface, and the rear outer wall surface of the inner box 4, each of the two lateral moving mechanisms 5 is provided with an elastic slider 7, and the two lateral moving mechanisms 5 are spaced apart in the up-down direction. Through the support nature and the removal reliability of two positions about box 4 in order to guarantee through two upper and lower sideslip mechanisms 5 and two elastic sliding blocks 7, avoid the switch board only when upside or downside receive the striking, interior box 4 to one side incline, that is to say can guarantee through this kind of mode that interior box 4 receives the stability when striking.

The working principle of the lifted piece 6 is as follows: when the right side of switch board received the striking, left crossbar portion 61 moved left, because lifting surface 3a on the left lifting seat 3 sets up for oblique downwardly, along with left crossbar portion 61 continues to move left, left second gyro wheel 62 contacts lifting surface 3a to upwards lifting under lifting surface 3 a's effect, because the striking that the switch board received is generally more violent, and the impact is great, consequently left second gyro wheel 62 rises rapidly along lifting surface 3a, just can order to order about interior box 4 and upwards rush out outer box 1. Similarly, when the left side of the switch cabinet is hit, the right-hand crossbar 61 moves to the right, and immediately thereafter, the right-hand second roller 62 contacts the lifting surface 3a and is lifted upward by the lifting surface 3 a. When the front side of the switch board receives the striking, its analytic process refers to above, and this no longer gives details.

In some embodiments, as shown in fig. 2, 5, 8, and 9, two sets of lifting seats 3 are disposed on the left inner wall surface, the right inner wall surface, and the rear inner wall surface of the outer box 1, one of the two sets of lifting seats 3 is located at the lower side, and the other set is located at the upper side, wherein the two lifting seats 3 located at the lower side are disposed at intervals along the horizontal direction, the two lifting seats 3 located at the upper side are disposed at intervals along the horizontal direction, each lifting seat 3 is correspondingly disposed with a lifted piece 6, the orthographic projections of the two lifting seats 3 at the upper side are located between the orthographic projections of the two lifting seats 3 at the lower side, or the orthographic projections of the two lifting seats 3 at the lower side are located between the orthographic projections of the two lifting seats 3 at the upper side.
