DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] like Figure 1-4 The utility model discloses a frame-integrated rotating office chair, comprising a desk 1, a fixed plate 2 is arranged on the inner wall of the desk 1, a rotating cylinder 3 is rotatably arranged in the fixed plate 2, a fixed cylinder 4 is fixedly arranged on the rotating cylinder 3, an extension rod 5 is telescopically arranged in the fixed cylinder 4, a limiting strip 18 is arranged at the bottom of the extension rod 5, the limiting strip 18 slides in the fixed cylinder 4, the limiting strip 18 can prevent the extension rod 5 from rotating in the fixed cylinder 4, an end plate 19 is arranged at the end of the extension rod 5, the end plate 19 can prevent the extension rod 5 from being pulled out of the fixed cylinder 4, a connecting shaft 6 is arranged at the upper end of the connecting shaft 6, an office chair 7 is arranged at the upper end of the connecting shaft 6, the connecting shaft 6 is rotated in the extension rod 5 in a buckled rotating manner, a locking device 8 is arranged on the fixed plate 2 and the rotating cylinder 3, and a locking device 9 is arranged on the fixed cylinder 4 and the extension rod 5;

[0023] like Figure 1 and 3 The locking device 8 includes a pin rod 10, which passes through the fixed plate 2. An end cap 11 is provided at the upper end of the pin rod 10. A spring 12 is sleeved on the pin rod 10. One end of the spring 12 is fixed to the end cap 11 and the other end is fixed to the fixed plate 2. The spring 12 will always have a downward elastic force on the pin rod 10 to ensure that the pin rod 10 is inserted into the pin hole 14. A circular ring plate 13 is fixed to the rotating drum 3. A circular array of pin holes 14 is provided on the upper end surface of the circular ring plate 13. The pin rod 10 can be inserted into the pin hole 14. By inserting the pin rod 10 into the pin hole 14, the position of the rotating drum 3 can be locked to prevent the office chair 7 from rotating around the rotating drum 3 at will during office work.

[0024] like Figure 1 , 2 And 4, the locking device 9 includes a wire drum 15, which is arranged at the upper end of the fixed drum 4, and a bolt 16 is threadedly connected in the wire drum 15. A linear array of holes 17 are provided on the extension rod 5, and the bolt 16 can be inserted into the hole 17. By inserting the bolt 16 into the hole 17, the position of the extension rod 5 can be locked.

[0025] During specific use, when the office chair 7 needs to be used for office work, first pull the end cap 11 to pull the pin rod 10 out of the pin hole 14, then rotate the fixing tube 4 to rotate the office chair 7 out from the bottom of the desk 1, loosen the end cap 11, and under the action of the spring 12, the pin rod 10 will be inserted into the pin hole 14 again. If the position of the office chair 7 is not suitable, the position of the office chair 7 can be adjusted by pulling the extension rod 5. During the pulling process, the extension rod 5 will not rotate in the fixing tube 4 due to the limiting strip 18. At the same time, the end plate 19 can prevent the extension rod 5 from being pulled out of the fixing tube 4. By twisting the bolt 16, the bolt 16 is threaded into the wire tube 15, and the bolt 16 can be inserted into the socket 17, so that the position of the extension rod 5 can be locked.

[0026] After use, the office chair 7 can be rotated to the inside of the desk 1, which is also convenient for cleaning.
