The working principle of the dining chair of the embodiment is explained in detail as follows:

when the dining chair is in normal use, the sliding pin 922 of the state adjusting part 92 is located at one side of the state adjusting groove 911 and is located in the angle adjusting groove 712 and the second sliding groove 811, that is, the dining chair is in an angle adjusting state when in normal use, and the angle can be adjusted by directly pulling the pull handle 91. Specifically, the slide pin 922 of the state adjuster 92 passes through the state adjustment groove 911, the second slide groove 811, and the angle adjustment groove 712 in this order, the handle 91 moves upward in the accommodation groove 601 of the backrest 6, the angle adjustment plate 71 is moved upward by the slide pin 922 of the state adjuster 92, the slide pin 922 moves in the second slide groove 811, and the height adjustment plate 81 is not moved. The angle adjusting plate 71 moves upwards to drive the pulling rope 73 to move upwards, and then the bolt 74 is pulled to be disengaged from the socket 501 of the seat plate 5, so that the angle can be adjusted conveniently, and when the angle is adjusted to a proper angle, the bolt 74 is pushed by the first elastic piece 72 to be inserted into the corresponding socket 501, and the angle is adjusted.

As shown in fig. 5-10, when the height of the seat plate 5 needs to be adjusted, the status adjusting member 92 is moved to the other side of the status adjusting slot 911 by the sliding handle 921 along the direction X in the figure, the return elastic member 93 is compressed, so that the sliding pin 922 moves into the first sliding slot 711 and the height adjusting slot 812, the height adjusting plate 81 is driven to slide upwards by pulling the handle 91, the pulling cable 83 is driven to move upwards, the locking slider 841 at the lower end of the pulling cable 83 moves upwards, the locking member 842 is pushed away from the front bracket 1 along the sliding opening 8411 by the engagement of the first sliding inclined surface 8412 on the locking slider 841 and the second sliding inclined surface 8423 on the locking block 8421, that is, the locking member 842 moves along the direction Q in the figure and compresses the second elastic member 82, the locking pin 8422 escapes from the locking opening 101, and the position of the seat plate 5 on the front bracket. When the height is adjusted to a proper level, the locking member 842 is pushed by the second elastic member 82, and the locking pin 8422 is inserted into the corresponding locking hole 101, so that the fixing is completed and the height adjustment is completed. After that, the sliding pin 922 moves again into the angle adjustment groove 712 and the second sliding groove 811 by the elastic restoring member 93, i.e. the dining chair changes from the height adjustment state to the angle adjustment state, and the angle between the seat plate 5 and the backrest 6 can be adjusted by pulling the handle 91.

Compared with the prior art, the utility model discloses a dining chair integrates into one with the operating element of altitude mixture control's among the current dining chair operating element and angle modulation, can realize the position control between bedplate and the support and the angle modulation between bedplate and the back through same operating device, and is swift convenient.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
