Referring to the drawings, a chair comprises a backrest bracket 1 and a cushion bracket 2; a transverse jack 12 is arranged on the backrest bracket 1, the cushion bracket 2 is movably inserted into the transverse jack 12, and the backrest bracket 1 and the cushion bracket 2 form an X-shaped bracket structure together; the backrest support 1 is provided with a backrest portion 11, and the cushion support 2 is provided with a cushion portion 21.

When the chair is used as a chair, as shown in fig. 1 to 3, the cushion bracket 2 is movably inserted into the transverse socket, so that the backrest bracket 1 and the cushion bracket 2 form an X-shaped bracket structure together. By adjusting the insertion position of the cushion bracket 2 (the adjustment direction is shown by an arrow in fig. 1), the horizontal and transverse position of the cushion portion 21 can be adjusted, so that the chair can adjust the position of the cushion portion 21 relative to the backrest portion 11, can meet the sitting posture demands of different people, and is simple in adjustment mode.

As shown in fig. 4 to 7, a longitudinal accommodating groove 13 is provided in the back support 1, and the cushion support 2 is movably inserted into the longitudinal accommodating groove 13. When needs are accomodate, can insert cushion support 2 and establish in vertical accommodation groove 13, consequently this chair structure, back support 1 can accomodate cushion support 2, has effectively reduced the transportation, perhaps take up big problem of space when accomodating at the family.

Referring to fig. 3 and 4, the back support 1 includes two longitudinal bars 14 disposed parallel to each other, and first and second cross bars 15 and 16 connecting the two longitudinal bars 14; the first cross bar 15 is located on the back side of the longitudinal bar 14 and the second cross bar 16 is located on the front side of the longitudinal bar 14; the first cross bar 15 and the second cross bar 16 are arranged at intervals, and form the transverse socket 12 and the longitudinal accommodating groove 13 together with the inner side surfaces of the two longitudinal bars 14; and the first crossbar 15 is located at a position above the second crossbar 16. Further, reinforcing links 17 are provided on the front sides of the lower ends of the two longitudinal bars 14. By providing the reinforcing links 17, a further stabilizing effect is achieved for the two longitudinal bars 14.

By the above structure, the main structure of the backrest bracket 1 can be formed by the first cross bar 15, the second cross bar 16 and the two longitudinal bars 14, and the transverse socket 12 and the longitudinal accommodating groove 13 can be formed. As shown in fig. 5 to 7, when the cushion bracket 2 is stored, the cushion bracket 2 is inserted into the longitudinal accommodating groove 13 from the back of the backrest bracket 1, the cushion bracket 2 is positioned in the inner accommodating spaces of the two longitudinal rods 14 of the backrest bracket 1, and at this time, the cushion bracket 2 and the longitudinal rods 14 are in a parallel state, so that the occupied space is effectively reduced.

Referring to fig. 3, the backrest portion 11 includes a first rectangular frame 18, and rattan woven mesh provided in the first rectangular frame 18; the first rectangular frame 18 is fixedly connected at an upper position of the two longitudinal bars 14. The first rectangular frame 18 serves both to fix the rattan woven net and to fix the two longitudinal bars 14.

As shown in fig. 2, the cushion bracket 2 includes two cushion main beams 22 disposed parallel to each other, and a connecting rod 23 connecting the insides of the lower ends of the two cushion main beams 22. Further, the cushion portion 21 includes a second rectangular frame 24, and rattan woven nets provided in the second rectangular frame 24; the second rectangular frame 24 is fixedly connected to the upper portion of the cushion main beam 22. The second rectangular frame 24 not only plays a role in fixing rattan woven nets, but also plays a role in fixing the two cushion main beams 22. By arranging the connecting rods 23, the two cushion main beams 22 are further stabilized.

As shown in fig. 2 and 5 to 7, the width of the second rectangular frame 24 is larger than the outer widths of the two cushion main beams 22; when the cushion bracket 2 is inserted into the longitudinal accommodating groove 13, the second rectangular frame 24 is put on the back surfaces of the two longitudinal bars 14. Because the first cross bar 15 is located at the back side of the longitudinal bars 14, the second cross bar 16 is located at the front side of the longitudinal bars 14, when the cushion bracket 2 is inserted into the longitudinal accommodating groove 13, the second rectangular frame 24 is put on the back sides of the two longitudinal bars 14, and the front and the back sides of the cushion main beams 22 are respectively abutted against the first cross bar 15 and the second cross bar 16, when the cushion bracket 2 is accommodated, the cushion bracket 2 can be prevented from overturning, so that the cushion bracket 2 is ensured to be stably accommodated in the longitudinal accommodating groove 13. Meanwhile, the reinforcing connecting rod 17 can also form a limiting effect on the cushion main beam 22, so that the cushion bracket 2 is further prevented from overturning.

As shown in fig. 1, the lower ends of the cushion main beam 22 and the longitudinal rod 14 are arc-shaped, and the radians of the two are the same. By setting the cushion main beam 22 and the longitudinal bar 14 to an arc shape, it is advantageous to ensure that the cushion portion 21 is in a horizontal state and the backrest portion 11 is in a proper inclined state so as to satisfy the sitting posture demand. In addition, when the cushion bracket 2 is inserted into the longitudinal accommodating groove 13, the two cushion main beams 22 are ensured to be overlapped in the two longitudinal rods 14, and the cushion bracket is convenient to store.

As shown in fig. 1, a bolt hole 25 is provided in the cushion main beam 22, and a limit bolt is provided in the bolt hole 25. When the chair is used, when the cushion bracket 2 is inserted into a proper position, the limiting bolt can be utilized for limiting, and falling off between the cushion bracket 2 and the backrest bracket 2 can be avoided.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the specification and drawings of the present utility model or direct/indirect application in other related technical fields are included in the scope of the present utility model.
