[0032] Reference Figures 1 to 7 The utility model discloses a stowage bracket, comprising two oppositely arranged support frames 1, two oppositely arranged supporting frames 2, a connecting piece 3 and a connecting rod assembly 4, wherein the support frames 1 and the supporting frames 2 are both hinged to the connecting piece 3. In the present application, the support frame 1 is connected by a plurality of support rods to form a U-shaped structure, and the supporting frame 2 is connected by a plurality of frame rods to form a U-shaped structure. The support rods and the frame rods are preferably made of stainless steel pipes, and the support rods and the frame rods can be fixed to each other through an elastic marble structure, so that they can also be retracted. The elastic marble structure is an existing The structure is therefore not described in detail. When not folded, the two supporting frames 1 form an eight-shaped structure, and the supporting frames 2 are parallel to each other to form a supporting plane. The connecting member 3 is a square bar formed by plastic injection molding. A slot is provided in the connecting member 3. The connecting member 3 is not only a connecting part between the supporting frame 1 and the supporting frame 2, but also the end feet of the two supporting frames 1 are located in the corresponding slots and are hinged to the slot walls of the slots; and the end feet of the two supporting frames 2 are located in the corresponding slots and are hinged to the slot walls of the slots. In this way, the end feet are hidden in the slots, which is not only beautiful but also the sharp edges of the slots will not be exposed to hurt people.

[0033] As shown in the figure, the connecting rod assembly 4 is hinged to the corresponding supporting frame 1 and the supporting frame 2. Specifically, the connecting rod assembly 4 includes a connecting rod 1 and a connecting rod 2 hinged to the connecting rod 1. The connecting rod 1 is hinged to the supporting frame 2, and the connecting rod 2 is hinged to the supporting frame 1. Through the connecting rod assembly 4, the supporting frame 2 can be folded when the supporting frame 1 is folded.

[0034] As shown in the figure, it also includes a folding piece 1 5 and a folding piece 2 6, which are respectively hinged to the corresponding support frame 1, and the folding piece 1 5 and the folding piece 2 6 are hinged to each other and fixed by a snap-on structure to avoid relative rotation. The folding piece 1 5 and the folding piece 2 6 are also preferably made of bent stainless steel pipes. The folding piece 1 5 and the folding piece 2 6 are both in a "convex" shape with an open top, and there are two pins at the opening. The folding piece 1 5 is provided with a fastener box 7, and the two pins of the folding piece 1 5 are inserted into the fastener box 7 and fixed to the fastener box 7 by screws. The fastener box 7 is located between the two pins of the folding piece 2 6 and is hinged to the two pins of the folding piece 2 6. The top of the fastener box 7 is provided with a protruding card plate 8, and the fastener box 7 is provided with a snap-on piece 9 that can move in the fastener box 7. And an elastic member 12 for resetting the snap member 9, the specific structure is: the bottom of the snap member 9 is a square slider 10, and the snap box 7 is provided with a matching slide hole 11, the elastic member 12 is located in the slide hole 11, and a limiting structure is provided between the snap member 9 and the snap box 7 to prevent the snap member 9 from being pushed out of the snap box 7 by the elastic member 12. In the present application, the elastic member 12 is a spring, and in order to prevent the spring from swinging, the end of the slider 10 has an end hole, one end of the spring is located in the end hole and abuts against the end hole, and The other end of the spring abuts against the slide hole 11, and a block 13 is provided on the clip 9. The block 13 is located below the card plate 8 and has a certain distance from the card plate 8. When the clip 9 is squeezed and extended by the spring, the edge of the block 13 is flush with the edge of the card plate 8, so that the two side walls of the slot 14 are formed between the block 13 and the card plate 8, and a latch 15 that can be inserted into the slot 14 is provided on the folding member 6. The latch 15 is connected with the slot 14 to prevent the folding member 5 and the folding member 6 from rotating relative to each other. The structure of the body, the limiting structure includes a long hole set on the side wall of the fastener box 7, and the fastener 9 is provided with a limiting rod, one end of the limiting rod is located in the long hole, and the fastener 9 is limited by the limiting rod and the hole wall of the long hole to limit the fastener 9 from being pushed out by the spring. When the fastener 9 is pressed, the fastener 9 can squeeze the spring to drive the card block 13 to shrink into the fastener box 7. At this time, a notch appears on one side wall of the card slot 14, and the card pin 15 can escape from the card slot 14 through the notch, so that the folding member 1 5 and the folding member 2 6 can be rotated and folded.

[0035] As a preferred structure, a rope hole is provided in the fastener box 7, and a connecting plate 17 is provided on the fastener 9. One end of the pull rope 18 can pass through the rope hole and be fixed to the connecting plate 17, and the other end of the pull rope 18 can be connected to the middle part of the bottom end of the bathtub. The bathtub is made of waterproof cloth through heat fusion, so it is very soft. Therefore, the user does not need to bend down to press the fastener 9 when folding the bracket. He only needs to lift the middle part of the bathtub, and the bathtub will also fold in half and close. At the same time, the fastener 9 is pulled by the pull rope 18 to squeeze the spring and retract into the fastener box 7, so that the pin 15 can be disengaged from the notch and the slot 14, and this pulling force can lift the fastener box 7 upward, so that the folding member 1 5 and the folding member 2 6 are relatively rotated downward and closed, and then the folding member 1 5 and the folding member 2 6 respectively drive the corresponding support frame 1 to fold downward and inward, and the support frame 1 pulls the supporting frame 2 downward and rotates and closes through the corresponding connecting rod assembly 4, thereby folding into a stack. The hinge structure of the present application is a conventional structure commonly used in the art, and thus will not be described in detail.

[0036] The above is a detailed introduction to a folding and unfolding bracket provided in an embodiment of the utility model.
