The rotating frame 2 here comprises a second frame 21, a connecting plate 22 located in the middle of the second frame 21, the connecting plate 22 being rotatably connected to the central support 3 by means of bearings. It should be pointed out that the outer periphery of second square frame 21 is not less than the outer periphery of first square frame 11, as shown in fig. 1, the long limit of second square frame 21 extends one section more than the long limit of first square frame 11, when needs are rotatory, see fig. 2, the centre of a circle is used as the center in normal rotation, the corner of second square frame 21 can need more left side spaces (surpass the short sideline of second square frame 21), if adopt the technical scheme of the utility model, slide central support 3 earlier, make central support 3 take second square frame 21 to move to the right, thereby can reduce left side space when rotatory, convenient rotation. If a seat (see fig. 7-8) should be arranged on a high-speed rail, if the left side is close to a window and the right side is close to a passageway, the seat is arranged on a rotating frame 2, an underframe 1 is used for supporting, when the seat is turned over, the seat is pulled out (slid out) rightwards and then rotated, and then the seat is rotated and slid and reset, so that the material use of the underframe 1 can be reduced, the seat can be attached to a window wall, no gap is required to be reserved, and the width of the passageway is indirectly increased.

The rotating frame 2 needs to be stabilized when not rotating, the locking mechanism of the embodiment includes two sets of rotating locking modules for limiting the rotation of the rotating frame 2, the two sets of rotating locking modules are respectively arranged on two long sides of a square frame, each set of rotating locking modules includes a ball 41, a first spring 42, a cover plate 43 and a guide rail 45, a groove 14 is arranged on the bottom frame 1, the cover plate 43 is connected with the bottom frame 1 and presses the first spring 42 and the ball 41 in the groove 14, an opening is arranged on the cover plate 43, the diameter of the opening is smaller than that of the ball 41, and the installation of the ball 41 is shown in fig. 5. The guide rail 45 is arranged on the bottom surface of the rotating frame 2, the guide rail 45 is in a groove 14 shape, and the guide rail 45 is matched with the ball 41, so that the groove 14 shape of the guide rail 45 can be kept matched with the ball 41 to be made into an arc-shaped groove. In order to guide the rotating angle conveniently, the guide rail 45 consists of an arc-shaped channel 45-3 and a linear channel 45-4, the radian of the arc-shaped channel 45-3 is determined according to the rotating path of the rotating frame 2, the length of the linear channel 45-4 is consistent with the sliding distance of the central support 3 on the bottom frame 1, namely the sliding distance of the central support 3 is large, the length of the linear channel 45-4 is large, fit is guaranteed, preferably, one end of the linear channel 45-4 is crossed with the midpoint of the arc-shaped channel 45-3 to form a first concave point 45-1, the other end of the linear channel is provided with a second concave point 45-2, the first concave point 45-1 and the second concave point 45-2 are both matched with the outer contour of the ball 41, the depth of the arc-shaped channel 45-3 is the same as that of the linear channel 45-4, the depth of the first concave point 45-1 and the second concave point 45-2 are both larger, and the depth of second pit 45-2 is greater than the depth of first pit 45-1. When the rotating frame 2 is locked and does not rotate, the ball 41 is positioned in the second concave point 45-2, and when the rotating frame needs to rotate, the ball 41 rolls to the first concave point 45-1 to rotate. The arrangement of the first concave point 45-1 and the second concave point 45-2 changes the distance of the ball 41 ejected by the first spring 42 when the ball 41 is guided to roll, which is beneficial to guiding the sliding of the rotating frame 2 relative to the chassis 1, and simultaneously ensures that the rotating frame 2 can not swing stably when not rotating.

In order to enhance the stability of locking the rotating frame 2 and facilitate the rotation of unlocking, the locking mechanism of this embodiment includes a sliding locking module for limiting the sliding of the central support 3, as shown in fig. 1, the sliding locking module includes a fixing seat 51, a first connecting rod 52, a second connecting rod 53, a pin lock 54, and a pull rod 55, the fixing seat 51 is installed on the central support 3, the fixing seat 51 is provided with a sleeve hole 511, one end of the pin lock 54 passes through the sleeve hole 511 and is hinged with the second connecting rod 53, the first connecting rod 52, and the fixing seat 51 in sequence to form a connecting rod mechanism, the other end of the pin lock 54 is provided with a cap, a second spring is sleeved between the cap and the sleeve hole 511, one end of the pull rod 55 is hinged with the second connecting rod 53, a hinge point is arranged near the first connecting rod 52, the other end extends out of the outer frame of the chassis 1 and is provided with a handle 56. In a normal locking state, referring to fig. 3, due to the elastic force of the second spring, the pin lock 54 is forced to be inserted into the insertion hole 13, and simultaneously the second connecting rod 53 and the first connecting rod 52 are pulled to be in a straight line, and due to the cooperation of the pin lock 54 and the insertion hole 13, the central support 3 cannot slide, and in combination with the limit of the rotation locking module, the rotating frame 2 can be kept in a stable and fixed state; when the rotating frame 2 is unlocked, the handle 56 is pulled, the pull rod 55 drives the second connecting rod 53 and the first connecting rod 52 to rotate, the pin lock 54 is pulled out of the insertion hole 13 by overcoming the elastic force of the second spring, and after the pin lock 54 is separated from the insertion hole 13, the central support 3 can slide, the handle 56 is pulled continuously, and the rotating frame 2 can be pulled to a rotating position.

In this embodiment, the materials of the base frame 1, the rotating frame 2, the central support 3 and the locking mechanism are preferably metal members, and may be selected according to the requirements, such as large structural support, steel and alloy materials, and if daily use, structures such as wood and composite plates may be selected.
