Detailed Description

The present application is described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, an embodiment of the application discloses an adjustable desk and chair with a limiting structure, which comprises a seat cushion 1 and a height adjusting support assembly, wherein the height adjusting support assembly is used for adjusting the height of the seat cushion 1. The height-adjusting support assembly includes a first leg 2, a second leg 3, a reinforcing bar 4, and a base 5. The first supporting leg 2 and the second supporting leg 3 are respectively provided with two, the reinforcing rod 4 is fixedly connected between the two second supporting legs 3, and the base 5 is fixedly arranged at the bottom of the second supporting leg 3.

Referring to fig. 2 and 3, the upper end of the first supporting leg 2 is fixedly connected with the seat cushion 1, and the first supporting leg 2 and the second supporting leg 3 are provided with limit structures which are mutually matched and connected. The limiting structure comprises a limiting slot 61 formed on the second supporting leg 3, a limiting insert block 62 for being inserted and fixed in the limiting slot 61, an inserting hole 63 formed on the lower surface of the first supporting leg 2 and a pressing block 64 fixed on the side surface of the bottom of the first supporting leg 2. The insertion hole 63 extends in the length direction of the first leg 2, and the upper end of the second leg 3 is inserted into the insertion hole 63. The limiting slots 61 are symmetrically arranged on two opposite side surfaces of the second supporting leg 3, and a plurality of limiting slots 61 are arranged at intervals along the length direction of the second supporting leg 3. The limiting insert 62 is symmetrically inserted into the limiting slot 61, a part of the limiting insert 62 is inserted into the limiting slot 61, and the other part of the limiting insert 62 extends out of the limiting slot 61 to form an overhanging part 621. The pressing blocks 64 are symmetrically arranged on two opposite side surfaces of the first supporting leg 2, and the pressing blocks 64 are supported on the overhanging portions 621 in a pressing manner. The overhanging portion 621 is fixedly provided with an upward protruding bump 622, the pressing block 64 is provided with a groove 641 which is matched and inserted with the bump 622, and the bump 622 is inserted in the groove 641. The cross-section of the bump 622 is a right triangle, and the inclined surface of the bump 622 is higher at the side close to the second leg 3 than at the side far from the second leg 3. A gap 7 is formed between the projection 622 and the second leg 3, and the bottom of the first leg 2 can be inserted into the gap 7 and abut against the overhanging portion 621.

Referring to fig. 2 and 4, the second leg 3 is further provided with a communication hole 31 communicating with the limiting slots 61 on two opposite sides of the second leg 3, the communication hole 31 extends along the length direction of the second leg 3, and the width of the communication hole 31 is smaller than the width of the limiting slots 61 and is located at the middle position of the limiting slots 61.
