DETAILED DESCRIPTION

Technical solutions embodied in the embodiments of this disclosure will now be clearly and comprehensively described in connection with the accompanying drawings for these embodiments. Apparently, the described embodiments are merely some but not all embodiments of this disclosure.
Referring to FIGS. 1-8 , an elastic bed includes: a ring frame 1, composed of four connecting frames 2 that are pin-connected in sequence, where two adjacent connecting frames 2 can be folded in half relative to the other two connecting frames 2 through the transverse folding interface 3, and two adjacent connecting frames 2 can be folded in half through the longitudinal folding interface 4;
a mesh fabric 5 disposed inside the ring frame 1 and detachably connected with the ring frame 1;
a support leg interface 6 clamped on the outside of the ring frame 1, and the bottom of the support leg interface 6 defines a T-shaped groove 7; and
a support leg 8 having a T-shaped clamping portion 16 on the top which is matched with the T-shaped groove 7, wherein at least three sets of the supporting leg interface 6 and the supporting leg 8 are provided.
More specifically, both the transverse folding interface 3 and the longitudinal folding interface 4 each include a rotary seat 9 and an ear plate 10. The rotary seat 9 and the ear plate 10 are respectively fixed at the ends of the two adjacent connecting frames 2. The rotary seat 9 and the ear plate 10 are rotatably connected by a pin connection piece. The end surfaces of the rotary seat 9 and the ear plate 10 each define positioning holes 11, and the two sets of positioning holes 11 are fixed to each other by fixing pieces.
Both the pin connection piece and the fixing piece are implemented as bolts and nuts matched with the bolts.
Furthermore, the outer circumference of the mesh fabric 5 is distributed with multiple adhesive tape sets 12, and the mesh fabric 5 is fixed to the ring frame 1 by the adhesive tape sets 12. The adhesive tape set 12 includes a male tape and a female tape. The length of the male tape is longer than the length of the female tape to adjust the tightness. The male and female tapes are longer at one end and relatively shorter at the other end, which can be bound according to the requirements of elasticity.
More specifically, the connecting frame 2 is composed of two interlocking frames where one is sleeved inside the other. The end of the outer frame is provided with a catch portion 13, and both ends of the inner frame are each provided with a button 14 matching the catch portion 13.
Furthermore, the support leg interface 6 includes an upper rack 601 and a lower rack 602. The lower rack 602 has an arc-shaped opening 603 capable of clamping the connecting frame 2. A fixing pin set 604 is fixedly installed on the inner bottom of the arc-shaped opening 603, and the bottom of the connecting frame 2 is provided with a mounting hole set 15 that are arranged at intervals and that are matched with and can be inserted into the fixing pin set 604. Two sets of guide slots 606 are provided on both sides of the lower rack 602. The bottom of the lower rack 602 is provided with a gap 607 communicating with the guide slot 606. Both horizontal sides of the upper rack 601 are vertically bent to define two sets of insert legs 608. The insert leg 608 can be inserted into the inside of the corresponding guide slot 606, and the surface of the insert leg 608 is fixedly connected with a transverse protrusion 609 that can be snapped-fitted with the edge of the notch 607. The inner edge of the guide slot 606 is provided with a guide portion 605 for guiding the transverse protrusion 609. The bottom of the guide portion 605 and the gap 607 are not communicated to each other. The present disclosure realizes quick installation and disassembly of the support leg 8 by inserting and fixing the upper rack 601 to the lower rack 602, thus saving space required for carrying and storage. And the operation is simple. When in use, only the insert leg 608 needs to be inserted into the corresponding guide slot 606 and fixed by the transverse protrusion 609. The fixing pin set 604 provided in conjunction with the mounting hole set 15 can effectively prevent the support leg interface 6 from moving.
In the present disclosure, the mesh fabric 5 is fixed by the adhesive tape set 12, and one of the male and female tapes is long and the other short, which can be bound according to the requirements of elasticity. The ring frame 1 is provided with a longitudinal folding interface 4 and a transverse folding interface 3, so that the elastic bed can be folded to the minimum volume. In addition, each set of connecting frame 2 includes two sleeves or skeletons, which are contracted and then compressed again to facilitate storage, transportation, and use. The support leg interface 6 is snap-fitted with the ring frame 1 for easy disassembly and assembly. The support leg interface 6 is provided with a T-shaped groove 7, and the top of the support leg 8 is designed with a T-shaped clamping portion 16. When in use, only the support leg 8 needs to be inserted into the T-shaped groove 7 transversely, which is convenient and quick to install.
The foregoing merely portrays some illustrative implementations in accordance with the present disclosure, but the scope of protection of the present disclosure will not be limited thereto. Any equivalent replacements or modifications made by the person skilled in the art without departing from the technical scope disclosed by the present disclosure and based on the technical solutions and inventive concept of the present disclosure shall all be covered by the scope of protection of the present disclosure.
