Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1-2. A height-adjusting device for a student chair, which comprises a left connecting rod 5, a right connecting rod 7 and a connecting screw rod 6.
The left end of the left connecting rod 5 is provided with a first clamping ring 51, and the diameter of the first clamping ring 51 is larger than that of a connecting hole in the left connecting plate 2. Similarly, the right end of the right connecting rod 7 is provided with a second clamping ring 71, and the diameter of the second clamping ring 71 is larger than that of the connecting hole in the right connecting plate 4.
The middle part of the left connecting rod 5 is provided with a connecting hole for the connecting screw rod 6 to pass through, and the middle part of the right connecting rod 7 is also provided with a connecting hole for the connecting screw rod 6 to pass through.
A limiting plate 61 is sleeved on the connecting screw rod 6, and a threaded hole matched with the connecting screw rod 7 is formed in the middle of the limiting plate 61.
During installation, the left connecting rod 5 passes through the connecting hole on the left connecting plate 2, the connecting hole on the supporting leg 1 and the connecting hole on the right connecting plate 4 rightwards, and the first clamping ring 51 is in contact with the left connecting plate 2.
In a similar way, the right connecting rod 7 penetrates through the connecting hole in the right connecting plate 4, the connecting hole in the supporting leg 1 and the connecting hole in the left connecting plate 2 leftwards, and the second clamping ring 71 is in contact with the right connecting plate 4.
The connecting screw rod 6 firstly passes through the connecting hole on the left connecting rod 5 from bottom to top, then is sleeved with the limiting plate 61, and then passes through the connecting hole on the right connecting rod 7.
In this way, the left and right connecting rods 5 and 7 bear vertical force, and the left connecting rod 5 moves leftwards due to the existence of the connecting screw rod 6, so that the right connecting rod 7 moves leftwards, but the second snap ring 71 limits the right connecting rod 7 to move leftwards, so that the left connecting rod 5 is limited to move leftwards.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
