DETAILED DESCRIPTION

The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

Example:

Referring to Figures 1 to 3, the present application is an office chair that is easy to adjust when lying down, including a seat board 1 and a backrest 2. The backrest 2 is installed on one side of the seat board 1 and the bottom of the backrest 2 is adjustably installed on the seat board 1. This adjustment method can be a rotating structure or a clamping adjustment structure, which belongs to the common technology in the field. The present application will not repeat its specific structure. A support plate 3 is provided below the seat board 1. A fixed rod 4 is fixed between the seat board 1 and the support plate 3. A support assembly for supporting legs and feet is provided at the bottom of the seat board 1. The support assembly includes two sliding rods 5 and two L-shaped support rods 6. The two sliding rods 5 are slidably installed at the bottom of the seat board 1 and extend horizontally away from the backrest 2. A connecting rod 7 is fixed between the ends of the two sliding rods 5 away from the backrest 2. The ends of the longer sections of the two support rods 6 are rotatably installed on the connecting rod 7 through bearings. Torsion springs 8 are fixed between the two support rods 6 and the corresponding two sliding rods 5. The two support rods 6 can effectively rotate along the connecting rod 7 as the axis through the installed torsion spring 8 and extend between the seat plate 1 and the support plate 3. A connecting plate 20 is provided between the longer section and the shorter section of the two support rods 6, and the legs and feet can be effectively supported by the provided connecting plate 20. The connecting plate 20 here can also be provided in a rod shape, which can also support the legs and feet of the user.

As shown in Fig. 1 and Fig. 2, a first fixing assembly for limiting the support assembly in a sitting state is provided between the support plate 3 and the support assembly, the first fixing assembly includes a limiting block 9 and a spring 10, a limiting groove 11 is provided on the seat plate 1, the limiting block 9 is vertically slidably installed in the limiting groove 11, the spring 10 is fixedly arranged between the bottom of the limiting block 9 and the limiting groove 11, and an abutting rod 12 is provided between the two support rods 6, and one side of the limiting block 9 extending out of the limiting groove 11 is slidably abutted against the abutting rod 12. This arrangement can effectively push the limiting block 9 out of the limiting groove 11 through the spring 10, and make the limiting block 9 abut against the abutting rod 12 between the two support rods 6, so as to prevent the two support rods 6 from popping out in a sitting state.

As shown in Fig. 1 and Fig. 3, a second fixing component for limiting the position of the support component in the lying state is also provided between the support plate 3 and the support component. The second fixing component includes two sliding blocks 14 and two limiting rods 13. Two slide grooves 15 are provided on the support plate 3. The two sliding blocks 14 are respectively and correspondingly slidably installed in the two slide grooves 15. One end of the two limiting rods 13 is respectively hingedly installed on the corresponding sliding blocks 14. The other ends of the two limiting rods 13 are respectively hingedly installed on the corresponding support rods 6. The bottom of the two slide grooves 15 is provided with a plurality of evenly distributed clamping blocks 16. The bottom of the two sliding blocks 14 is provided with a plurality of evenly distributed clamping blocks 16. A plurality of engaging grooves 17 are provided on each of the parts for abutting against a plurality of engaging blocks 16 when the sliding block 14 slides in the direction away from the support rod 6. Each of the engaging blocks 16 and the engaging grooves 17 is a sliding surface with a slope in the direction away from the support rod 6, so that the two sliding blocks 14 can slide when moving in the direction of the support rod 6. Each of the engaging blocks 16 and the engaging grooves 17 is a vertical abutting surface on a side close to the support rod 6, which can prevent the two sliding blocks 14 from sliding in the direction away from the support rod 6. A fixing groove 18 is provided on the side wall of the slide groove 15, and a fixing block 19 is fixedly provided on the side wall of the sliding block 14. The fixing block 19 slides and extends into the fixing groove 18. The fixing block 19 is arranged to extend into the fixing groove 18, so that the sliding block 14 can be prevented from completely sliding out of the slide groove 15. The height of the fixing block 19 is less than the height of the fixing groove 18. In this way, the fixing block 19 can drive the sliding block 14 to move up and down in the fixing groove 18 and the slide groove 15, so that the clamping groove 17 at the bottom of the sliding block 14 can be disconnected from the clamping block 16. A pulling handle 21 is fixedly provided between the two limit rods 13. In this way, the two limit rods 13 and the sliding block 14 can be conveniently lifted by pulling the handle 21, so that the clamping groove 17 at the bottom of the sliding block 14 can be disconnected from the clamping block 16.

Working principle:

When in use, first adjust the chair back 2 on one side of the seat plate 1 to a suitable lying position. After the adjustment is completed, when support for the legs and feet is needed, the limit block 9 is stepped on to disconnect the limit block 9 from the abutment rod 12. At this time, the support rod 6 will be rotated and lifted upward along the connecting rod 7 as the axis with the rebound force of the torsion spring 8. When adjusted to a suitable position, the legs and feet are placed on the connecting plate 20 between the two support rods 6. By applying downward pressure to the support rod 6 and the limit rod 13, the snap-in groove 17 at the bottom of the sliding block 14 is abutted against the snap-in block 16.

When it is necessary to return to the sitting position, one only needs to pull the handle 21 to lift the two limit rods 13 and drive the sliding block 14 to cancel the abutment relationship between the clamping groove 17 and the clamping block 16, and then further press down the connecting plate 20 to make the abutment rod 12 between the two support rods 6 abut against the limit block 9 again, and then adjust the angle of the chair back 2 to return to the sitting position.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
