[0018] Please refer to Figures 1-4 , an office chair ABS armrest facilitating installation, including an armrest rod 4 and a seat bottom plate 1. A limit card slot 6 is arranged on the upper side of one end of the lower part of the armrest rod 4, a jack 3 corresponding to the position of the armrest rod 4 is arranged on the seat bottom plate 1, a limit card block 7 is arranged on the upper side inside the jack 3, a spring 8 is arranged on the upper side of the limit card block 7, a damping rod 9 is arranged at the center of the spring 8, a shaft hole 10 is arranged on the lower side of one end of the limit card block 7, a first magnet 11 is arranged on the bottom side inside the jack 3, and a second magnet 12 is arranged on the lower side of the armrest rod 4 corresponding to the position of the limit card slot 6.

[0019] The first magnet 11 and the second magnet 12 can stably fix the armrest feeling 4 inside the jack 3, thereby stably connecting the armrest rod 4 and the seat bottom plate 1 and improving the installation efficiency of the armrest rod 4. The limit card block 7 can be stably clamped inside the limit card slot 6 under the action of the spring 8 and the damping rod 9, thereby quickly fixing the armrest rod 4 on the seat bottom plate 1.

[0020] Bolt holes 2 are arranged at both ends of the upper part of the seat bottom plate 1, and a handrail handle 5 is arranged on the upper side of the handrail rod 4.

[0021] The handgrip 5 can support the user's elbow to improve comfort.

[0022] The handrail rod 4 and the handgrip handle 5 are an integrated structure, and the handrail rod 4 is connected to the seat bottom plate 1 through the insertion hole 3 and the limit block 7.

[0023] The upper end of the damping rod 9 is connected to the seat bottom plate 1 by screws, and the lower end of the damping rod 9 is glued to the limit block 7.

[0024] The damping rod 9 and the spring 8 can make the limiting block 7 stably inserted into the limiting slot 6, thereby making the armrest rod 4 stably connected to the seat bottom plate 1.

[0025] The spring 8 is connected to the seat bottom plate 1 through a slot, and the No. 1 magnet 11 is glued to the seat bottom plate 1 .

[0026] The second magnet 12 is glued to the handrail 4, and the seat bottom plate 1 is supported by cast iron.

[0027] The inner side of the shaft hole 10 is hexagonal.

[0028] When the handrail 4 needs to be removed, a hexagonal shaft is inserted into the shaft hole 10 to lift the limit block 7 upward so that the limit block 7 is disengaged from the limit slot 6, and then the handrail 4 can be pulled out of the socket 3.

[0029] When in use, the seat base 1 is fixed to the seat frame through the bolt hole 2. When the armrest rod 4 needs to be installed, the lower end of the armrest rod 4 is inserted into the socket 3. The limit block 7 can be stably inserted into the limit slot 6 under the action of the spring 8 and the damping rod 9, so that the armrest rod 4 is firmly connected to the socket 3. The No. 1 magnet 11 and the No. 2 magnet 12 can make the armrest rod 4 and the seat base 1 firmly connected to ensure the connection strength. At the same time, it simplifies the installation steps of the armrest, improves the installation efficiency, and makes the armrest easy to install.
