In the deployed position, the right front upright frame 22 is located on the front side of the right grab rail 23, and the right grab rail auxiliary rod 24 and the right rear upright frame 25 are arranged one above the other and located on the rear side of the right grab rail 23.

The cross frame 3 in this embodiment is composed of two front and rear groups, and includes a front folding frame 31 provided between the left front upright frame 12 and the right front upright frame 22, and a rear folding frame 32 provided between the left rear upright frame 15 and the right rear upright frame 25. In the folding process of the folding chair, the left support and the right support are relatively close to fold under the condition that the transverse frame is transversely folded left and right. In order to stabilize the left side frame 1 and the right side frame 2 in the front-rear direction when they are unfolded, a left folding frame 11 is provided between the left front vertical frame 12 and the left rear vertical frame 15, and a right folding frame 21 is provided between the right front vertical frame 22 and the right rear vertical frame 25. Four groups of folding frames including a left folding frame 11, a rear folding frame 32, a right folding frame 21 and a front folding frame 31 are respectively and sequentially arranged among the four vertical frames of the left front vertical frame 12, the left rear vertical frame 15, the right rear vertical frame 25 and the right front vertical frame 22.

The left front upright 12, the left rear upright 15, the right rear upright 25 and the right front upright 22 respectively include an upright s1 extending in the vertical direction and an upright slider s2 provided to slide in the vertical direction on the upright s 1. In order to make the four groups of folding frames operate synchronously, a vertical rod s1 and a vertical rod sliding piece s2 are shared between every two adjacent groups of folding frames.

The details are as follows:

the front folding frame 31 is disposed between the two uprights s1 and the two upright sliders s2 of the left and right front uprights 12 and 22, and the rear folding frame 32 is disposed between the two uprights s1 and the two sliders s2 of the left and right rear uprights 15 and 25.

In this embodiment, as shown in fig. 1, 2, and 4, the front folding leg 31 and the rear folding leg 32 are respectively V-shaped folding legs. The detailed structure of the V-shaped folding frame is as follows:

the V-shaped folding frame comprises a V-shaped rod V1, one end of which is pivotally connected with one side vertical rod s1 through a V-axis zv1, a V-shaped two-rod V2, one end of which is pivotally connected with the other side vertical rod s1 through a V-axis zv2, a V-shaped three-rod V3, one end of which is pivotally connected with a vertical rod slide s2 positioned below the V-axis zv1 through a V-axis zv3, and a V-shaped four-rod V4, one end of which is pivotally connected with a vertical rod slide s2 positioned below the V-axis zv2 through a V-axis zv4, the V-shaped one rod V1 and the V-shaped three-rod V3 are pivotally connected through a V-axis zv5, the V-shaped two-rod V2 and the V-shaped four-rod V4 are pivotally connected through a V-axis zv6, and the other end of the V-shaped three-rod V3 is pivotally connected with the other end of the V-shaped four-rod V4 through a V-axis zv 7.

And when the folding chair with the armrests is in the unfolded position, the other end of the V three-rod V3 is abutted against the other end of the V four-rod V4, and a rotating point V seven-axis zv7 between the other end of the V three-rod V3 and the other end of the V four-rod V4 is lower than a connecting line between the V three-axis zv3 and the V four-axis zv4 and is also lower than a connecting line between the V five-axis zv5 and the V six-axis zv 6.

The one-way limiting mechanism is that abutting parts are respectively arranged between the abutting end parts of the V three-rod V3 and the V four-rod V4, and the V three-rod V3 and the V four-rod V4 cannot rotate when abutting against each other. Firstly, under the action of a one-way limiting mechanism, a rotating point at the rotating position between a V three-rod V3 and a V four-rod V4 is only allowed to move upwards, namely to be folded; secondly, the rotating part between the two is moved downwards under the action of the one-way limiting mechanism to form a limit position, the limit position is that the V seven-axis zv7 is in a dead point state, and the limit position is an unfolding position of the foldable support frame, at the moment, the limit position and the V three-axis zv3, the V four-axis zv4 or the V five-axis zv5 and the V six-axis zv6 respectively form a triangle, the V seven-axis zv7 is positioned below, if the foldable support frame is folded, the V seven-axis zv7 needs to be pulled upwards by manpower, and force between the left mechanism and the right mechanism is overcome in the process. When the foldable support frame is in the unfolding position, particularly under the condition of being weighted, the left side and the right side apply force to the center direction of the V seven-axis zv7 respectively, as long as the rigidity of the V three-rod V3 and the V four-rod V4 is strong enough, the folding frame can be unfolded more stably, the foldable support frame is locked at the unfolding position without using other locking mechanisms, and the foldable support frame is unfolded in place and automatically enters the locking state. The operation is very convenient.

Not shown in the figure, the rotation axes between the V three-rod V3 and the V four-rod V4 can be two rotation shafts, the one-way limiting mechanism adopts an intermediate connecting piece, the V three-rod V3 and the V four-rod V4 are respectively connected with two ends of the intermediate connecting piece in a rotating mode, and when the V three-rod V3 and the V four-rod V4 are unfolded, the ends of the V three-rod V3 and the ends of the V four-rod V4 are respectively abutted against the intermediate connecting piece and cannot rotate any more. Can only be rotated in the opposite direction to allow folding.

One bar V1 intersects with the V three bar V3 and is pivotally connected at the intersection by a V five axis zv5, the V two bar V2 intersects with the V four bar V4 and is pivotally connected at the intersection by a V six axis zv6, and the other end of the V one bar V1 is pivotally connected with the other end of the V two bar V2 by a V eight axis zv 8. In the unfolded position, the V three-rod V3 and the V four-rod V4 are approximately in a straight shape in the unfolded limit position, and the V one-rod V1 and the V two-rod V2 which are connected through the V eight-shaft zv8 are in an inverted triangle in the unfolded position, so that the unfolded position is further stabilized.

That is, in the present embodiment, when the folding chair is in the unfolded position and the front folding leg 31 and the rear folding leg 32 are respectively unfolded to the extreme positions, the distance between the left front standing frame 12 and the right front standing frame 22 is uniquely determined, and the distance between the left rear standing frame 15 and the right rear standing frame 25 is uniquely determined. Therefore, the relative positions between the upright s1 and the upright slider s2 of the left front upright 12, the left rear upright 15, the right rear upright 25 and the right front upright 22 are uniquely determined, and the unfolding stability of the left folding leg 11 and the right folding leg 21 is also determined.

The left folding leg 11 is arranged on the left front vertical leg 12 and has the following detailed structure:

the left folding leg 11 is disposed between the two uprights s1 and the two upright sliders s2 of the left front upright 12 and the left rear upright 15, and the right folding leg 21 is disposed between the two uprights s1 and the two upright sliders s2 of the right front upright 22 and the right rear upright 25. In this embodiment, as shown in fig. 1, 2 and 5, the left folding leg 11 and the right folding leg 21 are X-shaped folding legs, respectively. The X-shaped folding frame comprises an X rod X1, one end of which is pivotally connected with one side upright post s1 through an X shaft zx1, and an X two rod X2, one end of which is pivotally connected with the other side upright post s1 through an X two shaft zx2, wherein the X rod X1 is intersected with the X two rod X2 and is pivotally connected with the X five shaft zx5 at the intersection, the other end of the X rod X1 is pivotally connected with an upright post slide s2 positioned below the X two shaft zx2 through an X four shaft zx4, and the other end of the X two rod X2 is pivotally connected with an upright post slide s2 positioned below the X shaft zx1 through an X three shaft zx 3. Therefore, when the front folding leg 31 and the rear folding leg 32 are unfolded or folded, the left folding leg 11 and the right folding leg 21 can be synchronously controlled to be unfolded or folded through the sliding relationship between the upright rod sliders s2 and the upright rod s 1. Namely, the left front upright frame 12, the left rear upright frame 15, the right rear upright frame 25 and the right front upright frame 22 are simultaneously expanded outward or synchronously drawn toward the center.

As shown in fig. 1, the corners of the soft seat surface are fixed between the four vertical rods s1 of the left front vertical frame 12, the left rear vertical frame 15, the right rear vertical frame 25, and the right front vertical frame 22, and the soft seat surface is positioned above the left folding frame 11, the rear folding frame 32, the right folding frame 21, and the front folding frame 31, respectively.

A soft surface is provided between the front rod 51 and the rear rod 52. The object placing device is unfolded or folded along with the synchronous operation of the four groups of folding frames.

As shown in fig. 1 and 2, a left backrest strut 41 is slidably disposed on the upright bar s1 of the left rear upright frame 15 along the vertical direction thereof, a right backrest strut 42 is slidably disposed on the upright bar s1 of the right rear upright frame 25 along the vertical direction thereof, lower ends of the left backrest strut 41 and the right backrest strut 42 are respectively connected to upright bar sliders s2 corresponding to the lower portions thereof, and a backrest soft surface is disposed between an upper portion of the left backrest strut 41 and an upper portion of the right backrest strut 42. The left backrest support rod 41 and the right backrest support rod 42 are synchronously pressed downwards or pulled upwards, the vertical rod sliding parts s2 below are synchronously driven to slide, and therefore the four groups of folding frames are simultaneously driven, the folding chair is unfolded or folded, and when the folding chair is unfolded, the front folding frame 31 and the rear folding frame 32 are respectively positioned under the unfolding limit position, namely the folding chair is locked.

In this embodiment, the two groups of folding legs, namely the front folding leg 31 and the rear folding leg 32, are respectively V-shaped folding legs, so as to achieve the self-locking effect during unfolding.
