In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example one

As shown in fig. 1 to 5, in the present embodiment, a table structure for use on the back of a seat of a train or an airplane includes a table support and a table, one end of the table support is hinged to a seat mounting arm for mounting the seat, the other end of the table support is hinged to the table, a rotating buckle is disposed on the back of the seat, the rotating buckle can limit the free end so that the free end and the seat move synchronously, the seat is connected to the seat mounting arm 4 in a sliding manner, and the seat swings around a certain point in the front-back direction of the seat, and this embodiment of the bottom support of the seat or the seat mounting arm 4 is not limited, and only needs to satisfy the condition that the seat can swing, i.e., swing around a certain point to move back and forth. The table plate support and the table plate hinged part are provided with a telescopic compensation mechanism; when the seat swings, the compensation mechanism works to prevent the table plate from separating from the rotating buckle limit state.

Specifically, the seat is supported by the seat mounting arm 4 and can be swung. When the table is not used, the table is limited on the back of the seat by the rotary buckle, and when the table is used, the table is separated from the rotary buckle for limiting, so that the function of the table 8 can be used. When the seat is swung, the seat mounting arm 4 is fixed and cannot be swung, and the table plate is also not swung. If the seat swings, the track of the seat can be changed, at the moment, if the desk is not used, the desk is limited at the back of the seat, the desk can not be separated from the rotation buckle limit only by the telescopic change of the connecting part of the desk and the desk bracket during the swinging of the seat, referring to the principle shown in figure 2, the rotation radius R1 of the seat, after the seat rotates for a certain angle, the position of the desk 8 is also changed, if the rotation buckle limit is kept, the desk needs to move downwards by the distance of L1 to adapt to the position change of the seat, and the scalability of the compensation mechanism is needed.

This embodiment the compensation mechanism includes slide rail 81, first slider 83, first spring 86, slide rail 81 is the slot-like, and slide rail 81 sets up at table 8 side, and the both ends head of slide rail 81 is equipped with dog 82, first slider 83 and slide rail 81 sliding connection, and set up between two dogs 82, the available lug shape of first slider 83 guarantees that it is spacing also to slide. The two ends of the first spring 86 are respectively connected with the first slider 83 and the stopper 82 far away from the rotating shaft 9, the first spring 86 is in a compressed state, and the first slider 83 and the stopper 82 are provided with spring mounting columns 87 for facilitating connection with the first spring 86. The rotating shaft 9 is arranged on the side surface of the first sliding block 83, the side surface of the first sliding block 83 is also provided with a stop pin 84, and the end of the table support 7 close to the table 8 is provided with an arc groove 701 matched with the stop pin 84.

When the table support 7 supports the table 8 horizontally, one fulcrum is provided with the rotating shaft 9, and the other point is provided with the limiting stop pin 84 of the arc groove 701. The arc groove 701 is arranged to facilitate the rotation and retraction of the table board 8, when the stop pin 84 reaches the top of the arc groove 701, the arc groove 701 plays a limiting and supporting role for the stop pin 84. The first spring 86 is compressed, and in a normal state, the first spring 86 causes the first slider 83 to approach the table support 7, even though the table 8 and the table support 7 are extended to the longest state. When the seat is near standing position, need table 8 and table support 7 to be the longest state, the seat swing back is the posture of lying on the back, and table 8 and table support 7 are the state of shortening this moment, overcome first spring 86's elasticity and can shorten, therefore, when table 8 is spacing behind the seat, the seat rotates, and first spring 86 satisfies the scalability of table and table support junction for providing a telescopic distance. When the table 8 is used, the first spring 86 pushes the first sliding block 83 to the end of the table support 7, the rotating shaft 9 and the arc groove 701 provide support, the table 8 is kept horizontal, normal use of the table 8 is met, the supporting height of the table support 7 is unchanged, and the horizontal height of the table 8 is consistent when the table 8 is used no matter whether the seat rotates or not.

In order to ensure that the first spring 86 is not compressed randomly when the table plate 8 is used horizontally, a spring plunger 85 for locking the position of the first slider 83 is further arranged on the side surface of the first slider 83, the first slider 83 is provided with a convex mounting hole 83-1, the spring plunger 85 comprises a plunger rod 85-2 and a plunger cap 85-3, the plunger cap 85-3 is in a boss shape and is provided with a column hole, the plunger rod 85-2 is sleeved in the column hole and is in sliding connection, the plunger rod 85-2 is provided with a blocking piece, the plunger rod 85-2 is in sliding connection with the inner wall of the mounting hole 83-1, the plunger cap 85-3 is in threaded connection with the mounting hole 83-1, a compressed second spring 85-1 is arranged in the convex mounting hole 83-1, one end of the plunger rod 85-2, far away from the plunger cap 85-3, is a cylindrical head, the table plate 8 is provided with a groove 801, the edge of the groove 801 is a bevel. Referring to fig. 5, the spring plunger 85 is cylindrical, when the installation is performed, the second spring 85-1 is firstly pressed in the installation hole 83-1, the plunger rod 85-2 extends into the installation hole 83-1, the plunger cap 85-3 is screwed in the installation hole 83-1, the plunger rod 85-2 slides with the small diameter opening of the installation hole 83-1, and the second spring 85-1 pushes the plunger rod 85-2 into the groove 801. The inclined plane of the groove 801 is arranged to facilitate the sliding in or out of the cylinder head, the groove 801 arranged here is used for the horizontal support of the table plate 8, and therefore the groove 801 is arranged at the end of the sliding rail 81 close to the seat plate support frame. When the sliding block is used, the first spring 86 pushes the first sliding block 83 to force the cylindrical head to enter the groove 801, and the groove 801 plays a certain limiting role to enable the position of the first sliding block 83 to be stable; when the desk plate 8 is folded, the cylindrical head can slide out of the groove 801 only by overcoming the elastic force of the second spring 85-1.

When 8 spacing seats in the back at the table, for avoiding spring plunger 85 spacing to shrink the influence, first slider 83 is greater than the seat and rotates the flexible volume of needs table and table support on the guide rail, and the cylinder head gets into recess 801 and is unfavorable to stretching out and drawing back when avoiding compensation mechanism to stretch out and draw back.

The compensation mechanism of the embodiment is realized by the telescopic sliding of the table plate and the table plate support, the telescopic requirement of the seat during rotation is met, and the spring plunger is arranged on the table plate, so that the position of the first sliding block can be locked, and the stability of the table plate during use is guaranteed.
