Elastic bed

Abstract

An elastic bed includes: a ring frame, comprised of four connecting frames that are pin-connected in sequence, where two adjacent connecting frames can be folded in half relative to the other two connecting frames through a transverse folding interface, and two adjacent connecting frames can be folded in half through a longitudinal folding interface; a mesh fabric, disposed inside the ring frame and detachably connected to the ring frame.

What is claimed is: 
     
         1 . An elastic bed, comprising:
 a ring frame, comprising four connecting frames that are pin-connected in sequence, wherein two adjacent connecting frames are operative to be folded in half relative to the other two connecting frames through a transverse folding interface, and wherein two adjacent connecting frames are operative to be folded in half through a longitudinal folding interface;   a mesh fabric, disposed inside the ring frame and detachably connected with the ring frame;   a support leg interface, clamped on an outer side of the ring frame, wherein a T-shaped groove is defined in a bottom of the support leg interface, wherein the support leg interface comprises an upper rack and a lower rack, wherein the lower rack comprises an arc-shaped opening operative to clamping and being fitted with the connecting frame, wherein a set of fixing pins is fixedly installed at an inner bottom of the arc-shaped opening, and a bottom of the connecting frame defines a set of mounting holes arranged at intervals that are configured to be inserted and matched with the set of fixing pins, wherein both sides of the lower rack each comprise a set of guide slots, and a bottom of the lower rack defines notches communicating with the guide slots, wherein both horizontal sides of the upper rack are each vertically bent to define a set of insert legs, wherein each insert leg is operative to be inserted into an inside of the corresponding guide slot, and a surface of the insert leg is fixedly connected with a transverse protrusion that is operative to be snap-fitted with an edge of the corresponding notch; and   a support leg, comprising a T-shaped clamping portion on top that is matched with the T-shaped groove.   
     
     
         2 . The elastic bed as recited in  claim 1 , wherein the transverse folding interface and the longitudinal folding interface each comprise a rotary seat and an ear plate, which are respectively fixed at the ends of two adjacent connecting frames, wherein the rotary seat and the ear plates are rotatably connected by a pin connection piece, wherein end surfaces of the rotary seat and the ear plate each define a positioning hole, and wherein the two positioning holes are fixed to each other by a fixing piece. 
     
     
         3 . The elastic bed as recited in  claim 2 , wherein both the pin connection piece and the fixing piece are each implemented as a bolt and a nut matched with the bolt. 
     
     
         4 . The elastic bed as recited in  claim 1 , wherein an outer circumference of the mesh fabric is distributed with a plurality of adhesive tape sets, and wherein the mesh fabric is fixed to the ring frame through the adhesive tape sets. 
     
     
         5 . The elastic bed as recited in  claim 4 , wherein each adhesive tape set comprises a male tape and a female tape, and wherein the male tape has a greater length than that of the female tape for adjusting tightness. 
     
     
         6 . The elastic bed as recited in  claim 1 , wherein the connecting frame comprises two interlocking frames where one is sleeved inside the other, wherein an end of an outer frame comprises a catch portion, and both ends of an inner frame are each provided with a catch portion button matching the catch portion. 
     
     
         7 . The elastic bed as recited in  claim 1 , wherein an inner edge of each guide slot defines a guide portion for positioning the transverse protrusion, and wherein a bottom of the guide portion is not communicated with the corresponding notch. 
     
     
         8 . The elastic bed according to  claim 1 , wherein the supporting leg interface and supporting leg are provided in at least three sets, wherein each set comprises one supporting leg interface and one supporting leg. 
     
     
         9 . The elastic bed according to  claim 2 , wherein the supporting leg interface and supporting leg are provided in at least three sets, wherein each set comprises one supporting leg interface and one supporting leg. 
     
     
         10 . The elastic bed according to  claim 3 , wherein the supporting leg interface and supporting leg are provided in at least three sets, wherein each set comprises one supporting leg interface and one supporting leg. 
     
     
         11 . The elastic bed according to  claim 4 , wherein the supporting leg interface and supporting leg are provided in at least three sets, wherein each set comprises one supporting leg interface and one supporting leg. 
     
     
         12 . The elastic bed according to  claim 5 , wherein the supporting leg interface and supporting leg are provided in at least three sets, wherein each set comprises one supporting leg interface and one supporting leg. 
     
     
         13 . The elastic bed according to  claim 6 , wherein the supporting leg interface and supporting leg are provided in at least three sets, wherein each set comprises one supporting leg interface and one supporting leg. 
     
     
         14 . The elastic bed according to  claim 7 , wherein the supporting leg interface and supporting leg are provided in at least three sets, wherein each set comprises one supporting leg interface and one supporting leg.
