[0023] Example:

[0024] Reference Figures 1-5The present application provides a seat tray, comprising a factory-shaped connecting rod 1, one end of the bottom of the connecting rod 1 is fixedly arranged on a seat armrest, and the other end of the connecting rod 1 is provided with a mounting block 2 that can turn over along the axial direction of the connecting rod 1. A mounting groove 14 is opened on one side of the mounting block 2, one end of the connecting rod 1 away from the seat armrest slidably extends into the mounting groove 14, a plurality of annular grooves 15 are opened on the connecting rod 1, and a plurality of annular protrusions 16 are arranged on the side wall of the mounting groove 14. The plurality of protrusions 16 slidably extend into the plurality of annular grooves 15 in one-to-one correspondence. With this arrangement, through the annular grooves 15 on the connecting rod 1 and the protrusions 16 in the mounting groove 14, stable rotation of the mounting block 2 at the end of the connecting rod 1 can be realized. As shown in Figure 3 , a limiting member for limiting the rotation of the mounting block 2 is further provided on one side of the mounting block 2. The limiting member comprises a cross pin 23 with a top cap and a spring 24. A cross groove 22 is opened at the end of the connecting rod 1, a cross hole 25 corresponding to the cross groove 22 is opened at the groove bottom of the mounting groove 14, the cross pin 23 is slidably penetrated in the cross hole 25, and the spring 24 is fixedly arranged between the top cap of the cross pin 23 and the mounting block 2. The cross pin 23 extends into the corresponding cross groove 22 through the cross hole 25, thereby limiting the rotation of the mounting block 2 relative to the connecting rod 1. A support rod 3 is rotatably arranged on the mounting block 2, a rotation groove 17 is opened on the mounting block 2, a bearing 18 is fixedly arranged on the rotation groove 17, the support rod 3 is penetrated in the rotation groove 17 and fixedly connected with the inner wall of the bearing 18, a damping ring 19 is arranged in the rotation groove 17, and the damping ring 19 abuts against the side wall of the support rod 3.

[0025] as shown in Figure 1 and Figure 2 , a tray plate 4 is arranged above the support rod 3, an adjustment assembly is arranged between the support rod 3 and the tray plate 4, the adjustment assembly comprises an adjustment plate 5, a connecting block 6, two limiting blocks 7 and an adjustment block 8. The adjustment plate 5 is fixedly arranged on a side of the tray plate 4 facing the support rod 3, an elongated chute 9 is opened on a side of the adjustment plate 5 away from the tray plate 4, the chute 9 extends horizontally along the length direction of the tray plate 4, the connecting block 6 is fixedly arranged on the support rod 3 and slidably penetrated in the chute 9. Limiting grooves 10 are respectively opened on inner walls of two opposite sides of the chute 9, the two limiting blocks 7 are fixedly arranged on two opposite sides of the connecting block 6 and respectively extend into the limiting grooves 10 on two sides of the chute 9. A plurality of adjustment grooves 11 linearly distributed along the length direction of the chute 9 are opened at the groove bottom of the chute 9, the adjustment block 8 is fixedly arranged at the top of the connecting block 6 away from the support rod 3, and is in sliding abutment with the side wall of one of the adjustment grooves 11. Through the abutting fit between the adjustment grooves 11 on the adjustment plate 5 at the bottom of the tray plate 4 and the adjustment block 8 respectively, position adjustment of the tray plate 4 in the length direction thereof is realized, and the limiting blocks 7 are mainly used for preventing the connecting block 6 from sliding out of the chute 9.

[0026] as shown in Figure 1 and Figure 4As shown, the pallet 4 has a grid-like reinforcing member on the side facing the support rod 3. The reinforcing member includes several vertical rods 12 and several horizontal rods 13. The vertical rods 12 are evenly fixed to the side of the pallet 4 facing the support rod 3, and one end of each horizontal rod 13 is fixed to one side of the adjusting plate 5. The other end of each horizontal rod 13 is fixed to the edge of the pallet 4 facing the support rod 3, and each horizontal rod 13 abuts against the side of the vertical rods 12 opposite to the pallet 4. The grid-like distribution of the vertical rods 12 and horizontal rods 13 effectively improves the supporting strength of the pallet 4. Figure 5 As shown, a side strip 20 is fixed on the side of the tray plate 4 away from the support rod 3, and a cup holder groove 21 is also provided on the same side of the side strip 20 on the tray plate 4.

[0027] Working principle:

[0028] The seat tray is fixed to the seat armrest at the bottom by the connecting rod 1, providing basic support. The mounting block 2 is fitted onto the top of the connecting rod 1 through a mounting groove 14 on one side. The annular protrusion 16 on the inner wall of the mounting groove 14 engages and slides with the annular groove 15 at the end of the connecting rod 1, allowing the mounting block 2 to be stably rotated along the axial direction of the connecting rod 1, adjusting the basic tilt angle of the tray. When it is necessary to lock this tilt angle, the spring 24 between the top cap of the cross pin 23 and the mounting block 2 pushes the cross pin 23 to slide through the cross hole 25 at the bottom of the mounting groove 14 and insert it into the cross groove 22 at the end of the connecting rod 1, forming a rigid connection, thereby completely preventing the mounting block 2 from rotating relative to the connecting rod 1. A support rod 3 is rotatably mounted on the mounting block 2 via a bearing 18. The damping ring 19 set in the rotation groove 17 continuously rubs against the side wall of the support rod 3, providing appropriate resistance, so that the support rod 3 can be horizontally rotated around its own axis when manually applied, and can maintain a stable angle when there is no external force.

[0029] When the position of the tray 4 needs to be adjusted, a long strip-shaped groove 9 extending along the length of the tray 4 is provided on the adjusting plate 5, and the connecting block 6 at the top of the support rod 3 slides through it; the limiting blocks 7 fixed on both sides of the connecting block 6 are respectively embedded in the limiting grooves 10 on the side walls of the groove 9 to prevent the connecting block 6 from coming out; the adjusting block 8 fixed on the top of the connecting block 6 can selectively slide against the side wall of one of the multiple adjusting grooves 11 opened at the bottom of the groove 9. By changing the position of the adjusting block 8 inserted into different adjusting grooves 11, the tray 4 can be linearly slid along its length and fixed in multiple positions, thereby adjusting the front and rear distance of the tray 4 relative to the user of the seat.
