[0013] When the user uses the present transformable seat frame, different experiences can be obtained by pushing the locking handle. When the rotating plate rotates, the swing rod is pushed forward to extend the foot pad frame.

[0014] When the user normally sits on the cushion of the present transformable seat frame, the general sitting posture is to back against the cushion, so that the user can exert a weight to make the cushion frame swing downward at the rear end. When the user sits on the seat without locking the rotating rod by the locking handle, the weight exerted on the rear end of the cushion of the user sitting on the seat makes the cushion frame swing downward at the rear end with the hole three of the cushion frame as the rotation center, and the front end of the cushion frame swings upward. The swing of the rear end of the cushion frame rotates the rotating plate with the hole two of the rotating plate as the rotation center, so that the swing rod pushes the foot pad frame forward, thereby extending the foot pad frame. The swing rod pushes the foot pad frame forward to drive the push frame to push forward, so that the included angle between the two rod members of the push frame expands from an acute angle to an obtuse angle. If the user drives the locking push rod to make the latch tightly clamped in the lock hole, the rotating rod is locked and cannot rotate, the position relationship between the auxiliary push rod and the cushion frame is fixed, the auxiliary push rod cannot rotate relative to the cushion frame, and then the main push rod cannot be pushed forward by the foot pad frame, so that the swing rod cannot be extended forward, and the rotating plate cannot rotate.

[0015] The handle pad frame fixedly installed on the cushion frame is fixedly installed with a hole plate, and the locking handle is movably installed in the hole plate, that is, the locking handle swings relative to the seat frame with the swing of the cushion frame, that is, if the cushion frame is deformed, the rotating rod rotates to drive the locking handle to rotate.

[0016] The seat frame is further provided with a swing rod limiting rod, and the swing rod limiting rod is movably connected with the hinge joints between the swing rod and the rotating plate, that is, the hinge joints are connected with the swing rod, the rotating plate and the swing rod limiting rod. The swing rod limiting rod is mainly used as a support structure to limit the swing rod from swinging leftward and rightward during the swing. Because the swing rod is relatively long, the rotating plate alone cannot effectively eliminate the swing of the swing rod to the left and right directions. Therefore, the swing rod limiting rod is additionally arranged based on the installation structure of the swing rod and the rotating plate.

[0017] The cooperation relationship between the holes refers to that a pin shaft is arranged between the holes to enable the holes to rotate relative to each other, so that two rod members corresponding to the cooperation relationship between the holes can rotate relative to each other.

[0018] Compared with the prior art, the present application provides a use purpose that the user directly pushes the locking handle to control whether the foot pad frame of the present transformable seat frame with the foot pad frame automatically extends when the user sits on the transformable seat frame.

DETAILED DESCRIPTION

[0033] The utility model will be described in further detail below in combination with the drawings.

[0034] Reference Figures 1-13: When the user sits on the seat, different experiences can be obtained by rotating the locking handle 41. Specifically, if the user does not lock the rotating rod 33 by the locking handle 41, when the user sits on the seat, the weight applied to the rear end of the seat cushion makes the seat cushion frame 2 swing downward at the rear end of the seat cushion hole 23, and the front end of the seat cushion frame 2 swings upward. The swing of the rear end of the seat cushion frame 2 rotates the rotating plate 7 around the rotating plate hole 72, and the front push of the swing rod 5 pushes the pad foot frame 1 forward, thereby extending the pad foot frame 1. The front push of the pad foot frame 1 by the swing rod 5 drives the push frame 3 to push forward, and the angle between the two rod members of the push frame 3 swings from an acute angle to an obtuse angle. If the user rotates the locking push rod 412 to make the latch 43 tightly clamped on the lock hole 422, the shape of the outer side of the locking column 411 and the inner side of the rotating rod 33 is matched, so that the locking column 411 limits the rotation of the rotating rod 33, that is, the position relationship between the secondary push rod 32 and the seat cushion frame 2 is fixed, and the secondary push rod 32 cannot rotate relative to the seat cushion frame 2. Further, the main push rod 31 cannot be pushed forward by the pad foot frame 1, so that the swing rod 5 cannot be extended forward, and the rotating plate 7 cannot be rotated, that is, even if the seat cushion frame 2 is subjected to the weight of the user, the pad foot frame 1 cannot be extended. At this time, the force applied to the rear end of the seat cushion frame 2 by the user is finally applied to the seat frame swing frame 63 through the rotating plate secondary rod 74 of the rotating plate 7, so that the seat frame swing frame 63 swings in a manner that the front end swings upward.

[0035] The preferred embodiments of the present application are described above, and it should be pointed out that for ordinary skilled persons in the art, without departing from the inventive concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
