[0023] A splicable leisure chair comprises a seat plate 6, a backrest 2 and a plurality of support legs 10, wherein a cylindrical fixing block 12 is fixedly connected to the top end of the inner side of the support leg 10, and limit blocks 15 are symmetrically arranged on the upper and lower parts of the outer ring surface of the fixing block 12, and circular grooves 17 are respectively provided at the front and rear ends on both sides of the seat plate 6, and an arc-shaped limit cavity 16 connected to the circular groove 17 is arranged inside the seat plate 6 and at the upper and lower parts of each circular groove 17, and one end of each limit cavity 16 passes outward to the side of the seat plate 6, and the limit block 15 is embedded in the end of the limit cavity 16 and rotated to the end of the limit cavity 16, so as to install the support leg 10 to the side of the seat plate 6.

[0024] The fixing block 12 and the circular groove 17 are both configured to be circular, so that the fixing block 12 can rotate after being inserted into the circular groove 17 .

[0025] When the support leg 10 is in a vertical state, the two limit blocks 15 are in a vertical direction and symmetrical up and down, and the openings of the two limit cavities 16 are also in a vertical direction. The support leg 10 is pushed inward in a vertical state, so that the fixing block 12 is inserted into the circular groove 17, and the limit block 15 is inserted into the opening of the limit cavity 16. Then the support leg 10 is rotated so that the two limit cavities 16 are rotated to the end of the inner cavity of the limit block 15, so that the support leg 10 cannot be pulled outward. At this time, the support leg 10 is in a tilted state.

[0026] A spring rod 7 is provided on one side of the support leg 10 and can penetrate to the inner side of the support leg 10 . Positioning grooves 9 matching with the spring rod 7 are provided on both sides of the seat plate 6 . When the support leg 10 is installed in place, the spring rod 7 is embedded in the positioning groove 9 .

[0027] In order to prevent the support leg 10 from tilting and deflecting inward during use after being installed, thereby causing deformation of the support leg structure, a spring rod 7 is provided on the support leg 10, and the inner end of the spring rod 7 passes through the inner side of the support leg 10. During the installation process, the inner end of the spring rod 7 is pressed against the side wall of the seat plate 6 and received into the support leg 10, so that the support leg 10 can be rotated and installed normally. When the support leg 10 is installed in place, the inner end of the spring rod 7 just corresponds to the positioning groove 9. Under the action of elastic force, the inner end of the spring rod 7 is stuck in the positioning groove 9, so that when there is no force in a special direction, the support leg 10 cannot rotate and remains stable.

[0028] When disassembly is required, the spring rod 7 only needs to be pulled outwards to disengage the inner end of the spring rod 7 from the positioning groove 9, and the support leg 10 can be rotated for disassembly.

[0029] The support legs 10 at the front and rear ends are inclined forward and backward respectively, and the two support legs 10 on the same side form an eight-shaped structure, so that after being installed in place, it is more stable when subjected to force and is not easy to deflect inwards and cause structural deformation.

[0030] Cushion materials are added to the surfaces of the seat plate 6 and the backrest 2 to improve the comfort of use.

[0031] A support column 18 is detachably provided between the two support legs 10 on the same side; an L-shaped groove 24 is provided on the front side of the support leg 10 , and L-shaped hooks 23 adapted to the L-shaped groove 24 are fixedly connected at both ends of the support column 18 .

[0032] After the two support legs 10 on the same side are installed in place, the support column 18 is inserted between the two support legs 10. The support column 18 tightens the two support legs 10 so that they cannot rotate inward. The support column 18 cooperates with the spring rod 7 to position the two support legs 10 on the same side and strengthen the support leg structure.

[0033] A positioning assembly is detachably provided on the rear side of the seat plate 6 , and the backrest 2 is supported by the positioning assembly and its tilt angle is adjusted.

[0034] The positioning assembly includes a placement box 4, a rack roller 14, a second rack 13, an arc groove 22 and a placement groove 21. The placement box 4 is detachably arranged on the rear side of the seat plate 6. The rack roller 14 is transversely arranged at the axis of the placement box 4. The second rack 13 has multiple and spaced surfaces of the rack roller 14. The two ends of the inner wall of the placement box 4 are respectively provided with arc grooves 22 concentric with the rack roller 14. The two ends of the inner wall of the placement box 4 and the inner annular surface of the arc groove 22 are spaced apart with multiple placement grooves 21. The two sides of the backrest 2 are fixedly connected with support rods 5 extending to the inner cavity of the placement box 4. The surface of the support rods 5 is provided with moving blocks 20 that move in the arc groove 22 and the placement groove 21. The bottom of the support rod 5 is fixedly connected with an arc-shaped rack plate 8. The bottom of the rack plate 8 is fixedly connected with multiple first racks 11 that can mesh with the second rack 13.

[0035] The positioning assembly can be disassembled by snapping, and an opening is provided on the top of the placement box 4 for the support rod 5 to move, so that the support rod 5 can rotate on the placement box 4.

[0036] The moving block 20 has the same curvature as the arc groove 22, so that when the moving block 20 enters the arc groove 22, it is close to the inner wall of the arc groove 22, so that the moving block 20 can move along the trajectory of the arc groove 22 in the arc groove 22, but cannot move or flip in the backrest 2, thereby guiding and limiting the movement of the support rod 5.

[0037] Under normal conditions, the backrest 2 and the support rod 5 will press the rack plate 8 downward under the action of gravity, so that the first rack 11 clamps the second rack 13. At the same time, the moving block 20 on the side wall of the support rod 5 enters the placement groove 21. The two work together to prevent the support rod 5 from rotating, thereby supporting the support rod 5 and the backrest 2, thereby positioning the inclination angle of the backrest 2.

[0038] When the inclination angle of the backrest 2 needs to be adjusted, the backrest 2 and the support rod 5 are pulled outward along the length direction of the support rod 5, so that the moving block 20 moves from the placement groove 21 to the arc groove 22, and at the same time, the first rack 11 is disengaged from the second rack 13, so that the support rod 5 can move, and then the backrest 2 and the support rod 5 are rotated so that they rotate mainly around the axis of the placement box 4, and the moving block 20 moves in the arc groove 22. After rotating to a suitable position, the support rod 5 is inserted inwardly so that the moving block 20 enters the corresponding placement groove 21, and at the same time, the first rack 11 is engaged with multiple second racks 13 at another location, and the angle of the backrest 2 and the support rod 5 is fixed again, completing the adjustment of the angle of the backrest 2.

[0039] A headrest 1 is detachably provided on the top of the backrest 2 .

[0040] When the height or angle of the headrest 1 needs to be adjusted, it can be removed and reinstalled.

[0041] A seat cushion 19 is detachably provided on the top of the seat plate 6 , and armrests 3 are detachably provided on both sides of the seat plate 6 .

[0042] The handrail 3 is fixed by means of a snap connection.

[0043] The seat cushion 19 can be connected by zippers, buttons or Velcro, and users can replace or remove the seat cushion 19 at any time according to their needs, which is convenient for cleaning and maintenance.

[0044] The working principle of the splicable leisure chair provided by the utility model is as follows: by pushing the supporting leg 10 inward in a vertical state, the fixing block 12 is inserted into the circular groove 17, the limiting block 15 is inserted into the open end of the limiting cavity 16, and then the supporting leg 10 is rotated so that the two limiting cavities 16 are rotated to the ends of the inner cavity of the limiting block 15, so that the supporting leg 10 cannot be pulled outward. At this time, the supporting leg 10 is in an inclined state, and the inner end of the spring rod 7 just corresponds to the positioning groove 9. Under the action of elastic force, the inner end of the spring rod 7 is inserted into the positioning groove 9, so that when there is no force in a special direction, the supporting leg 10 cannot rotate and remains stable. When disassembly is required, only the spring rod 7 needs to be pulled outward to disengage the inner end of the spring rod 7 from the positioning groove 9, and the supporting leg 10 can be disassembled. Rotate for disassembly. When the inclination angle of the backrest 2 needs to be adjusted, pull the backrest 2 and the support rod 5 outward along the length direction of the support rod 5, so that the moving block 20 moves from the placement groove 21 to the arc groove 22. At the same time, the first rack 11 is disengaged from the second rack 13, so that the support rod 5 can move. Then rotate the backrest 2 and the support rod 5 so that they rotate mainly around the axis of the placement box 4, and the moving block 20 moves in the arc groove 22. After rotating to a suitable position, insert the support rod 5 inward so that the moving block 20 enters the corresponding placement groove 21. At the same time, the first rack 11 is engaged with multiple second racks 13 at another location, and the angle of the backrest 2 and the support rod 5 is fixed again. The adjustment of the angle of the backrest 2 is completed, and then the armrest 3 is snap-connected and installed.
