The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1 and 2, an office chair comprises a seat plate 1, a plurality of vertical supporting legs and two armrests 8 with a frame structure, wherein the supporting legs are arranged at the bottom of the seat plate 1, the two armrests 8 are respectively and fixedly arranged at two sides of the seat plate 1 and are opposite to each other, two first mounting blocks 9 are horizontally and oppositely fixed at one side of each armrest 8 opposite to the seat plate 1, a horizontal second rotating shaft 10 is rotatably connected between the two first mounting blocks 9, a placing plate 14 is fixed on the second rotating shaft 10, a third threaded hole 11 is respectively formed at the position, close to two ends, of the second rotating shaft 10, two second threaded holes 13 are formed in each armrest 8, and the two third threaded holes 11 are used for being in one-to-one correspondence with the two second threaded holes 13 after being rotated outwards along with the second rotating shaft 10 to the level of the placing plate 14.

The utility model discloses in the use, when the user need place article, the user rotates places board 14, until two third screw holes 11 in the second pivot 10 and two second screw holes 13 one-to-one on the handrail 8, then with the help of outside bolt precession second screw hole 13 and the third screw hole 11 that corresponds, this kind of design is through placing board 14 and fixing to second pivot 10 on, rotate and place board 14 and make two second screw holes 13 one-to-one on third screw hole 11 and the handrail 8, reach with this and adjust the horizontally purpose with placing board 14, thereby the user just can place article, and the usability is improved.

As shown in fig. 1, the supporting leg includes a vertical rod 4 and a vertical cavity rod 5, the top of the rod 4 is connected with the bottom of the seat plate 1, the bottom of the rod 4 is vertically penetrated into the cavity rod 5 from the top of the cavity rod 5, the rod 4 can slide relative to the cavity rod 5, a row of first threaded holes 6 distributed vertically are formed in the rod 4, a first bolt 7 screwed into any first threaded hole 6 is connected to the cavity rod 5, when the height of the supporting leg needs to be adjusted, a user firstly screws out the first bolt 7, then adjusts the rod 4 to vertically slide, and then screws the first bolt 7 into the first threaded hole 6 corresponding to the first bolt 7 after the rod 4 slides, and the overall height of the supporting leg can be adjusted. As shown in figure 1, the bottom of the cavity rod 5 is provided with a plurality of anti-skidding grooves 23, and the design mode can ensure that the support is firmer and the friction is increased.

As shown in fig. 1, the bottom of seat board 1 is rotated and is connected with butt plate 2, wear to establish the top of pole 4 and the bottom fixed connection of butt plate 2, after user's seat is gone up to seat board 1, and when user's needs faced different orientation, user's this moment just can rotate seat board 1 to rotate the orientation that user's needs, improved the flexibility. As shown in figure 1, be fixed with vertical first pivot 3 on the butt plate 2, first pivot 3 wears to establish on bedplate 1 and both can rotate relatively, and this kind of design has realized the rotation of bedplate 1 to the rotation mode is simple, and the practicality is strong.

As shown in fig. 1, the seat plate 1 is provided with a backrest 15 at one side, and a user can rest on the backrest 15 by arranging the backrest 15, so that the design increases the comfort, as shown in fig. 1, the backrest 15 is provided with a cushion 16, and the design enables the user to rest on the cushion 16 at rest, thereby being more comfortable. As shown in fig. 1, the cushion 16 is detachably sleeved on the backrest 15, the two sides of the backrest 15 are respectively clamped with a plurality of U-shaped clamping blocks 17, the U-shaped groove of each clamping block 17 is used for clamping the cushion 16 on the backrest 15, the cushion 16 can be fixedly sleeved on the backrest 15 by the design mode, and the cushion 16 cannot move or fall off when a user leans against.

As shown in fig. 1 and 3, a mounting groove 22 is formed in one side of the seat plate 1, a third rotating shaft 18 which is horizontal and perpendicular to the second rotating shaft 10 is rotatably connected to the mounting groove 22, the backrest 15 is fixedly connected to the third rotating shaft 18, a plurality of through holes 19 which are uniformly distributed are formed in the third rotating shaft 18 along the circumferential direction of the third rotating shaft, a second mounting block 20 is fixed to the outer side of the seat plate 1, an insertion rod 21 which can slide along the horizontal direction penetrates through the second mounting block 20, the insertion rod 21 is used for being inserted into any through hole 19 after sliding, and the inclination angle of the backrest 15 can be adjusted by a user in such a way, so that the use habits of different users are facilitated, and the design mode can realize locking after rotation of the third rotating shaft 18 by inserting the insertion rod 21 into the corresponding through hole 19, so as to fix the inclined backrest 15, and is simple in structure and convenient to operate.

The working principle is as follows:

firstly, a user unscrews the first bolt 7, slides the penetrating rod 4 up and down to adjust the height to a proper value, and then screws the first bolt 7 into the cavity rod 5, so that the first bolt 7 is in threaded connection with the corresponding first threaded hole 6 on the penetrating rod 4.

Then, the user sleeves the cushion 16 on the backrest 15, and clamps the plurality of clamping blocks 17 on the left and right edges of the backrest 15 to clamp the cushion 16, thereby completing the fixation.

Then, the user adjusts the backrest 15 to a proper inclination angle, and then horizontally slides the insertion rod 21 to insert the insertion rod 21 into one of the through holes 19, thereby fixing the backrest 15.

Next, the user rotates the placing plate 14 until the two third threaded holes 11 in the second rotating shaft 10 correspond to the two second threaded holes 13 in the armrest 8 one by one, and then screws in the bolts with the help of the external bolts to connect the bolts with the third threaded holes 11 and the second threaded holes 13, so as to fix the placing plate 14, and at this time, the user can place an article on the placing plate 14.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
