DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] See also Figure 1 In this embodiment, a combination table and chair with a corrective backrest includes a seat 1, a backrest 2 is fixed to the left side of the top surface of the seat 1, a support component 3 is provided below the seat 1, universal wheels 4 are fixed at the four corners of the bottom surface of the support component 3, a support column 5 is fixed between the center of the bottom surface of the seat 1 and the center of the top surface of the support component 3, a table body 6 is provided on the right side of the seat 1, table legs 7 are fixed at the four corners of the bottom surface of the table body 6, and an adjustment mechanism 8 is provided on the table body 6.

[0023] See also Figure 1-3 In order to facilitate the adjustment of the distance between the backrest 2 and the table body 6, the adjustment mechanism 8 includes a fixing component arranged on the table body 6, a supporting component arranged on the fixing component, an adjusting component arranged on the supporting component and a limiting component arranged on the adjusting component.

[0024] Among them, the fixing component includes fixing plates 801 fixed on the left and right sides of the middle position of the bottom surface of the table body 6, and a fixing rod 802 fixed between the opposite sides of the two fixing plates 801. The fixing component is mainly used to support the supporting component.

[0025] At the same time, the support component includes an L-shaped connecting rod 803 rotatably connected to the outer surface of the support column 5. The left rotatable connecting rod 803 is arranged so that the seat 1 can be rotated around the table body 6 within a certain range, making it more convenient for the user to leave the seat. Fang Boyi, the support component also includes a support spring 804 movably mounted on the right side of the outer surface of the fixed rod 802. When the connecting rod 803 is pushed to move to the right, the support spring 804 is squeezed and has elastic potential energy directed to the left. The elastic potential energy of the support spring 804 can be used to improve the convenience of adjusting the connecting rod 803 left and right.

[0026] In addition, a fixing hole is opened at the top of the right side of the connecting rod 803, and the fixing rod 802 passes through the fixing hole and is slidably connected thereto. The fixing rod 802 passes through the fixing hole to support the connecting rod 803 without affecting its left and right movement process.

[0027] In addition, the adjustment component includes a T-shaped slider 808 fixed at the top right side of the connecting rod 803, and the adjustment component also includes a fixed seat 805 fixed at the center of the bottom surface of the table body 6, and a T-shaped slide groove 806 opened on the bottom surface of the fixed seat 805 and slidably connected to the T-shaped slider 808. The setting of the T-shaped slide groove 806 and the T-shaped slider 808 allows the T-shaped slider 808 to move in the T-shaped slide groove 806 but will not fall off from the T-shaped slide groove 806.

[0028] It should be noted that the limiting assembly includes a limiting groove 807 opened in the middle position of the front side of the fixing seat 805, and the limiting assembly also includes a threaded groove 809 opened at the center of the front side of the T-shaped slider 808, and a threaded rod 810 that passes through the limiting groove 807 and extends to the inside of the threaded groove 809. The coordinated use of the threaded rod 810 and the threaded groove 809 can realize the limiting effect on the T-shaped slider 808 and improve its stability.

[0029] It should be emphasized that the front of the threaded rod 810 is fixed to a handle 811 extending to the front of the fixing seat 805, and the threaded rod 810 is inserted into the threaded groove 809 and threadedly connected thereto. The threaded connection method has higher stability.

[0030] The working principle of the above embodiment is:

[0031] When in use, the horizontal distance between the backrest 2 and the table body 6 can be corrected according to the user's needs to improve the user's experience. Specifically, the horizontal distance between the backrest 2 and the table body 6 can be adjusted by pulling or pushing the connecting rod 803 to move left and right in the T-shaped slide groove 806. When it is adjusted to a suitable position, the threaded rod 810 is rotated by the handle 811 to move toward the back and inserted into the threaded groove 809 opened at the center of the front of the T-shaped slide block 808. At this time, the handle 811 is tightly fitted with the limiting groove 807, so as to realize the limiting effect on the top right side of the connecting rod 803, thereby improving the stability between the connecting rod 803 and the table body 6 during use.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
