[0021] To make the technical solutions and beneficial effects of the present invention clearer, the following further elaborates on the embodiments of the present invention.

[0022] A movable table frame for a theater auditorium includes a tabletop 100, a backrest card seat 200, and a support arm 300. Among them, the backrest card seat 200 is arranged at the rear of the support arm 300, and the upper ends of the backrest card seat 200 and the support arm 300 are connected to the bottom of the tabletop 100. A card slot is provided at the lower part of the backrest card seat 200 for clamping the backrest. A clamping device for clamping on the seat armrest or the seat cushion is provided at the lower end of the support arm 300.

[0023] The backrest card seat 200 can be fixedly connected to the lower part of the table board 100. At this time, the backrest card seat 200 can be a section of channel steel with the opening facing downward, and its upper end is fixedly connected to the table board. The backrest card seat 200 can be set as an inverted U-shaped card slot. The U-shaped card slot can be set to have a certain width, so as to achieve a better stabilizing effect. The U-shaped card slot can also be formed by bending a strip of metal into a U shape. The upper end of the U-shaped card slot is fixedly connected to the table board. Preferably, the middle part of the upper end of the U-shaped card slot is rotatably connected to the table board 100, and a locking mechanism is provided to fix the U-shaped card slot at a specific angle. At this time, the angle of the U-shaped card slot can be adjusted to adapt to backrests of different thicknesses. For example, the thickness of the backrest of a sofa cushion is generally more than 10 cm, while the thickness of the backrest of a plastic seat is about 1 cm. When the U-shaped card slot is set to be 10 cm, when it needs to be installed on a plastic seat for use, rotate the U-shaped card slot so that the two sides of the U-shaped card slot are respectively abutted against the seat back, so that the combination of the backrest card seat 200 and the seat back can be more stable.

[0024] The way of rotational connection can be screw connection, and it can be fixed at a certain angle after rotation. Or a ratchet wheel can be provided on the rotational connection mechanism, and the angle can be adjusted by rotation and maintained at a certain angle. Or a rotational connection mechanism with damping is provided to connect the backrest card seat 200 and the table board 100. The rotational connection described in this embodiment refers to the rotational connection in the horizontal plane, that is, the axis of the rotating shaft of the backrest card seat 200 is in the vertical direction.

[0025] Preferably, for the convenience of storage, the upper end of the support arm 300 is hingedly connected to the table board 100. As shown in the figure, two backrest card seats 200 are provided and arranged at both ends of the rear part. One support arm 300 is provided and arranged in the middle of the two backrest card seats 200. By setting the way of hinged connection, the support arm 300 can be rotated to an angle parallel to the table board 100, thereby reducing the space required for its storage.

[0026] As shown in the figure, in this embodiment, the support arm 300 and the clamping device arranged at the end of the support arm 300 form a triangular shape, thereby increasing its stability. Since the clamping device is arranged at the end of the support arm 300, in this embodiment, the support arm can also be set as a straight rod and further set as a telescopic rod to achieve the effect of adapting to seats of different specifications.

[0027] In this embodiment, the clamping device is an inverted U-shaped frame, and the U-shaped frame is used to be clamped on the seat armrest. Locking bolts are arranged on both side walls of the U-shaped frame, and clamping plates are rotatably connected to the inner sides of the locking bolts. In order to protect the seat, rubber pads are arranged outside the clamping plates. Rotating handles are arranged on the outer sides of the locking bolts, and the locking bolts are screwed to the U-shaped frame.

[0028] In addition, for some seats without armrests, the U-shaped frame can be set horizontally, that is, the opening of the U-shaped frame faces the back of the seat. When fixing is required, the U-shaped frame is clamped on the seat cushion and then fixed with a locking bolt.

[0029] Preferably, to increase stability, the backrest card seat 200 is made of an elastic material, and at the same time, the caliber of the opening of the card slot of the backrest card seat is smaller than the caliber of the bottom of the card slot. At this time, when inserting the backrest, it is equivalent to being clamped on the backrest, which is more firm, reliable and stable.

[0030] Preferably, combination components are provided at the left and right edges of the table board 100. The combination components are provided in pairs, such as buckle or snap components, including a movable lock and a fixed lock, and the movable lock and the movable lock are respectively provided at the left and right ends of the table board. When multiple table boards 100 need to be spliced into a long table board, they can be connected and combined through the combination components. In addition, when the combination component is set as a snap component, it includes a snap main body and an insertion piece, which is similar to inserting a seat belt into a seat belt socket. Screws and nuts can also be set for combination.

[0031] In summary, it is only the preferred embodiment of the present invention and is not used to limit the scope of the present invention. Through the above description, relevant staff can make various changes and modifications completely within the scope of not deviating from the technical idea of this invention. The technical scope of the present invention is not limited to the content in the specification. All equivalent changes and modifications in terms of shape, structure, features and spirit as required by the present invention should be included within the scope of the claims of the present invention.
