An arc groove is formed on the surface of the guide seat. An active joint fulcrum is arranged at the center position of the arc groove. The lowest point of the arc groove is located below the active joint fulcrum. A limiting strip groove extending outward is formed at the lowest point of the arc groove. The extension line of the axis of the limiting strip groove passes through the center of the arc groove.

[0007] Guide rings are installed at the ends of the movable push rod. The guide rings are movably installed in the arc groove and the limiting strip groove. Strip grooves are formed on both side surfaces of the movable push rod. The active joint fulcrum is movably connected with the strip grooves. The shortest distance between the strip grooves and the guide rings is equal to the radius of the arc groove.

[0008] Preferably, a cable hanger is fixedly installed on the outer side surface of the main body bracket.

[0009] Preferably, the included angle between the main body bracket and the support inclined frame is 140 - 160 degrees.

[0010] Preferably, the pivot point of the movable joint includes a fixed strut. One end of the fixed strut is fixedly connected to both side surfaces of the support inclined frame. The guide seat is fixedly installed on the outer surface of the fixed strut. The other end of the fixed strut is provided with a threaded column. A limit nut is threadedly connected to the threaded column.

[0023] To make the purpose, technical solution and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model.

[0024] Example 1, as Figure 1-7 shown, a rotating mechanism of a compact mobile device includes a main body bracket 1 and a movable push rod 2. The main body bracket 1 is installed on the mobile trolley 11. A support inclined frame 3 inclined backward is arranged above the main body bracket 1. Guide seats 4 are fixedly installed on both side surfaces of the support inclined frame 3. An arc notch 5 is formed on the surface of the guide seat 4. A movable joint fulcrum 6 is arranged at the center position of the arc notch 5. The lowest point of the arc notch 5 is located below the movable joint fulcrum 6. A limit strip notch 7 extending outward is formed at the lowest point of the arc notch 5. The extension line of the axis of the limit strip notch 7 passes through the center of the arc notch 5;

[0025] Guide rings 8 are installed at the ends of the movable push rod 2. The guide rings 8 are movably installed in the arc notch 5 and the limit strip notch 7; Strip notches 9 are formed on both side surfaces of the movable push rod 2. The axis of the strip notch 9 coincides with the axis of the side surface of the movable push rod 2. The movable joint fulcrum 6 is movably connected to the strip notch 9; The shortest distance between the strip notch 9 and the guide ring 8 is equal to the radius of the arc notch 5.

[0026] Working principle:

[0027] In the initial state, the guide ring 8 at the end of the movable push rod 2 is clamped in the limit strip notch 7, so that the guide ring 8 at the end of the movable push rod 2 naturally stays at the bottom position of the guide seat 4 due to gravity. And because the strip notch 9 is connected to the movable joint fulcrum 6, the whole movable push rod 2 can be fixed obliquely upward through two-point positioning, as Figure 6 shown; The electric control cabinet is fixed on the support inclined frame 3; At this time, the whole mobile trolley 11 can be pushed forward and turned by the movable push rod 2.

[0028] When the electric control cabinet needs to be operated, the movable push rod 2 can be pulled backward, so that the guide ring 8 moves from the limit strip notch 7 to the arc notch 5, and then rotates counterclockwise along the arc notch 5, so that the guide ring 8 moves to the upper position of the arc notch 5, as Figure 7As shown in the figure, the movable push rod 2 can be naturally drooped to the bottommost position. At this time, the operator can operate the electric control cabinet at the rear side of the mobile trolley 11. In this embodiment, the height of the supporting inclined frame 3 is 1 meter. Therefore, the height of the operation buttons on the outer side of the electric control cabinet just meets the operation height of ergonomics, thus meeting the convenient operation of the electric control cabinet.

[0029] After the operation of the electric control cabinet is completed, the movable push rod 2 can be rotated clockwise again, so that the guide ring 8 moves to the position of the limiting strip-shaped notch 7, and then the movable push rod 2 is pushed forward, so that the guide ring 8 is clamped into the limiting strip-shaped notch 7, so that the movable push rod 2 returns to the initial state, and then the movable push rod 2 can be pushed to continue to push the mobile trolley 11 forward and turn.

[0030] Embodiment 2, as a further preferred solution of Embodiment 1, the included angle between the main body bracket 1 and the supporting inclined frame 3 is 140-160 degrees. In this embodiment, the included angle between the main body bracket 1 and the supporting inclined frame 3 is preferably 150 degrees. Thus, the operation surface of the electric control cabinet can be inclined, and then it is ensured that the operator does not need to bend down to observe the operation buttons of the electric control cabinet, thus more meeting the convenient operation of the electric control cabinet.

[0031] Embodiment 3, as a further preferred solution of Embodiment 1, a cable hanger 10 is fixedly installed on the outer side surface of the main body bracket 1. Through the cable hanger 10, the wiring cables of the electric control cabinet can be sorted out uniformly, avoiding the wiring cables of the electric control cabinet from dragging on the ground.

[0032] Embodiment 4, as a further preferred solution of Embodiment 1, the movable joint fulcrum 6 includes a fixed column 61. One end of the fixed column 61 is fixedly connected to the two side surfaces of the supporting inclined frame 3. The guide seat 4 is fixedly installed on the outer surface of the fixed column 61. The other end of the fixed column 61 is provided with a threaded column, and a limiting nut 62 is connected to the threaded column through threads. The strip-shaped notch 9 of the movable push rod 2 is sleeved on the outer surface of the threaded column and is rotatably connected to the threaded column. In this embodiment, two spacer pads are respectively sleeved on the threaded column, and the two spacer pads are respectively located on the inner and outer sides of the movable push rod 2.

[0033] During installation, one of the spacer pads can be first sleeved on the threaded column, then the strip-shaped notches 9 on the two side surfaces of the movable push rod 2 are respectively sleeved on the threaded column, and then the other spacer pad is sleeved on the threaded column. Finally, the limiting nut 62 is used for limiting, so that the movable push rod 2 can only move on the surface of the threaded column through the strip-shaped notch 9. The spacer pads are used to reduce the wear of the movable push rod 2 during movement.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
