[0020] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0022] Reference Figure 1 and Figure 2As shown, office chairs are various chairs equipped for the convenience of work in daily work and social activities. Most of them are chairs with backrests for sitting when working on a desk in a sitting state. The chassis structure of most existing office chairs is relatively simple and fixed. Most of them only have support columns 12 on the lower side of the seat, which greatly reduces the utilization space. In addition, in order to ensure stability, the chassis of office chairs is mostly hard. In order to solve these problems, an office chair chassis and an office chair are proposed, including a fixed base 1 and a support column 12 arranged in the fixed base 1. The upper side of the support column 12 is provided with a cushion for providing sitting conditions for office personnel. The outer circumference of the support column 12 is respectively provided with an internal thread 121, and the outer circumference of the lower section of the support column 12 is provided with a storage member 3, and the storage member 3 includes a threaded connection A plurality of storage plates 31 are arranged on the internal thread 121 of the support column 12, and a receiving groove 312 for placing articles is formed on the top of the plurality of storage plates 31. A plurality of buffer members 2 for buffering the downward pressure of the fixed base 1 are also arranged on the lower side of the fixed base 1. The setting of the fixed base 1 and the support column 12 can achieve the whole office chair being in a stable setting state, and the cooperation between the plurality of storage plates 31 in the storage member 3 and the internal thread 121 on the outer periphery of the support column 12 can achieve the up and down position adjustment of the storage plate 31 to the lower side of the seat cushion, and the receiving groove 312 is provided in the storage plate 31 to achieve the purpose of storing and protecting some carry-on articles, and the setting of the buffer member 2 can achieve the purpose of making the chassis of the office chair more stable.

[0023] It should be noted that, in the process of the above-mentioned plurality of storage plates 31 rotating up and down along the support column 12, they have two states. In the first state, the plurality of storage plates 31 are in a state of being stacked and stored with each other. At this time, the bottom storage plate 31 is attached to the top of the fixed base 1. At this time, the storage plate 31 will not affect the entire office chair transfer process; in the second state, the office chair is in use. At this time, the storage plate 31 is actively rotated along the support column 12 by humans, thereby achieving the purpose of adjusting the position of the storage plate 31.

[0024] Furthermore, in order to make the overall storage effect of the storage plate 31 better, in this embodiment, the top of the outer edge of the storage plate 31 protrudes upward to form a limit block 311 for limiting the receiving groove 312. The setting of the limit block 311 can achieve the purpose of limiting the outer side of the receiving groove 312, thereby ensuring that the placed items can be placed in the receiving groove 312 in an orderly manner.

[0025] In addition, in order to better protect the storage plate 31, in the present embodiment, a protective pad 32 is provided at the bottom of the storage plate 31 for protecting the storage plate 31 in its placed state; the bottom of the protective pad 32 is horizontally arranged for attachment to the fixed base 1; the horizontal arrangement of the protective pad 32 can achieve the purpose of better protecting the storage plate 31 when it is on the upper side of the fixed base 1.

[0026] It should also be noted that the specific structure of the above-mentioned buffer member 2 is as follows: the buffer member 2 includes a first slide groove 111 and a second slide groove 11 which are arranged in the fixed base 1 at intervals, a buffer plate 21 is provided in the second slide groove 11 for sliding up and down, a plurality of buffer springs 211 are provided between the buffer plate 21 and the top wall of the second slide groove 11, one end of the buffer spring 211 is provided on the top of the buffer plate 21, and the other end is provided on the top wall of the second slide groove 11, and a reset member for resetting the buffer plate 21 is provided on the upper side of the buffer plate 21; The setting of the buffer plate 21 and the buffer spring 211 can achieve that when the fixed base 1 touches the ground downward, the buffer plate 21 will contact the ground first, until it abuts the ground and then slides upward along the second slide groove 11. At this time, the buffer spring 211 will be subjected to pressure due to the sliding of the buffer plate 21, and the entire fixed base 1 will be more stable during the placement process. When the fixed base 1 is fixed, the entire fixed base 1 can form a better grip due to the setting of the buffer plate 21, and the setting of the buffer plate 21 can play another role, that is, the shock absorbing effect.

[0027] Furthermore, in the process of transferring the entire office chair, in order to better reset the entire buffer plate 21, in this embodiment, the specific structure of the reset member is as follows: the reset member includes a plurality of guide slide rods 22 arranged on the top of the buffer plate 21, and the plurality of guide slide rods 22 extend upward into the first slide groove 111, and the guide slide rods 22 are provided with a reset slide plate 24 that slides vertically up and down along the first slide groove 111, and the top of the reset slide plate 24 is provided with a reset spring 23 for the reset slide plate 24 to reset and slide up and down; the guide slide rods 22 extend into the first slide groove 111 to achieve the purpose of orderly operation of the reset slide plate 24 and the reset spring 23, so as to ensure that when the buffer plate 21 is out of contact with the ground, the reset spring 23, the reset slide plate 24 and the guide slide rods 22 are set to ensure the reset of the entire buffer member 2, so as to ensure the purpose of continuous buffering of the fixed base 1 next time.

[0028] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
