It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Please refer to fig. 1 to 3. A detachable seat comprises a seat back 10, a seat board 20 and four support legs 30, wherein the number of the support legs 30 is four, the four support legs 30 are distributed at four end corners of the lower end face of the seat board 20 to support the seat board 20, and the seat back 10 is arranged on the upper end face of the seat board 20 to allow a user to lean on.

The chair back 10 comprises a tail part 13, a waist part 12 and a head part 11 which are sequentially connected from bottom to top, wherein a first shaft hole 101 is formed in the end part of one side of the waist part 12 and the end part of one side of the seat board 20, and the chair back 10 is sleeved on the rotating shaft 14 through the first shaft hole 101 and is connected with the seat board 20 through the rotating shaft 14. End covers (not shown) are arranged at two ends of the rotating shaft 14, and the area of each end cover is larger than that of the first shaft hole 101 so as to limit the rotating shaft 14 and prevent the rotating shaft 14 from generating displacement in the axial direction of the first shaft hole 101.

Preferably, the tail portion 13 is provided with a stop plate 131, the end portion of the seat plate 20 is provided with a limit structure 203, and the seat back 10 can be rotated until the stop plate 131 abuts against the limit structure 203. In this embodiment, the limit structure 203 is disposed in a stepped groove shape in the middle of one side end of the seat plate 20, as shown in fig. 5, the first shaft holes 101 are disposed at two ends of the limit structure 203, and the stop plate 131 is vertically disposed on the seat back 10 in a straight plate shape, as shown in fig. 3; after the backrest 10 is connected to the seat plate 20 through the rotating shaft 14, one end of the tail 13 is disposed on the step surface of the limiting structure 203, the backrest 10 can rotate to make the stop plate 131 abut against the end surface of the limiting structure 203, and the backrest 10 is limited by the limiting structure 203 and supported for a user to lean against.

Preferably, the seat back 10 is inverted C-shaped, as shown in FIG. 2, such that the waist 12 is closer to the middle of the seat pan 20 than the tail 13; in this embodiment, afterbody 13, waist 12, head 11 are platelike, and afterbody 13 is cut to 12 directions of waist by the hinged end with bedplate 20, so that afterbody 13 is middle part fretwork form, as shown in fig. 3, when using the seat, the middle part fretwork department of back of the chair 10 afterbody 13 can be used to place user's buttock, make the user lumbar vertebrae under the position of sitting state be natural curvature, back of the chair 10 waist 12 can contact with user's waist in order to provide the support simultaneously, alleviate lumbar vertebrae pressure, thereby promote the use travelling comfort of seat.

Referring to fig. 1 to 6, the bottom surface of the seat plate 20 is provided with four sliding grooves 201 for receiving the supporting legs 30, and the number of the sliding grooves 201 corresponds to the number of the supporting legs 30. Specifically, the sliding groove 201 is a T-shaped groove, a second shaft hole 204 penetrating the sliding groove 201 in the width direction is provided at an end of the sliding groove 201, a short shaft (not shown) is provided at an end of the supporting leg 30, and the supporting leg 30 is rotatably connected with the seat plate 20 by the short shaft being engaged with the second shaft hole 204. Since the sliding slot 201 is a T-shaped slot, the sliding slot 201 can be regarded as two slots communicating with each other in the vertical direction, and the slot located below the sliding slot is used for accommodating the supporting leg 30. Preferably, the length of the sliding slot 201 is greater than or equal to the length of the supporting leg 30, and when the folding seat is folded, the supporting leg 30 can be rotated into the slot hole of the supporting leg 30 below the sliding slot 201, so as to reduce the volume of the folded seat.

The support rod 40 is used for assisting in supporting the support leg 30, one end of the support rod 40 is rotatably connected with the support leg 30, the other end of the support rod 40 is rotatably connected with a slide block 42, and the slide block 42 is slidably arranged in the slot above the sliding slot 201. The slide block 42 and the sliding groove 201 are both provided with connecting holes 202, and the connecting holes 202 extend from the inner wall of the sliding groove 201 to the end surface of the seat plate 20; the fixing piece 41 is further included, the fixing piece 41 can connect the sliding block 42 and the sliding groove 201 through the connecting hole 202, the sliding block 42 is limited in the sliding groove 201, and the sliding block 42 is fixed relative to the sliding groove 201.

When the support leg 30 is unfolded and in a supporting state, because one end of the support leg 30 is rotatably arranged in the sliding groove 201, when the support leg 30 rotates to a certain angle, the side surface of the support leg 30 is abutted against the end surface of the sliding groove 201, and the support leg 30 is limited (the angle is determined by the shape of the support leg 30, the inclination degree of the outer surface of the support leg 30 and the inclination degree of the end surface of the sliding groove 201); meanwhile, in the rotating process of the support leg 30, the support bar 40 swings therewith, when the support leg 30 rotates to the extreme position, the slider 42 correspondingly moves to the extreme position (similar to a crank rocker mechanism), at the moment, the fixing piece 41 is matched with the connecting hole 202, the slider 42 is fixed in the sliding groove 201, and the support leg 30 cannot rotate reversely because the support bar 40 is fixed, so that the support leg 30 and the support bar 40 are fixed simultaneously and cannot rotate and swing, the support leg 30, the support bar 40 and the seat plate 20 form a stable triangular structure, and as shown in fig. 2, the stability of the seat is ensured.

Preferably, the side wall of the leg 30 is provided with a receiving groove 301, and one end of the supporting rod 40 is rotatably disposed in the receiving groove 301. During storage, when the support legs 30 are folded and the support legs 30 are placed in the sliding grooves 201, the support rods 40 swing synchronously and are gradually stored in the storage grooves 301, so that the support legs 30 and the support rods 40 are synchronously folded when the seat is stored, and the occupied space of the seat after storage is reduced.

In this embodiment, the four sliding slots 201 are symmetrically disposed at the left and right sides of the seat board 20, and the mounting directions of the supporting legs 30 in the two sliding slots 201 on the same side are opposite, that is, one of the supporting legs 30 rotates backwards to become a supporting state, and the other supporting leg 30 rotates forwards to become a supporting state, so that the four supporting legs 30 are respectively located at four end corners below the seat board 20 after being unfolded, and the stability of the seat is higher.

As another implementation manner, four sliding grooves 201 may also be disposed on four sides of the seat plate 20, and the supporting legs 30 are installed in a clockwise or counterclockwise direction, which also achieves the effect that the supporting legs 30 are located at four corners of the seat plate 20 after being unfolded.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
