Abstract

The present invention relates to the technical field of mattresses, and particularly provides a high-elastic anti-deformation mattress. The high-elastic anti-deformation mattress includes a mattress assembly which includes a first layer, a second layer and a third layer from top to bottom in a sequence; a plurality of assembling chambers are formed in the second layer, and each assembling chamber is filled with a vertically upward spring; a large-diameter end of each spring is upwards close to a top portion of the corresponding assembling chamber, and a small-diameter end of each spring is downwards connected to a top surface of the third layer; a connecting base is inserted into a large end of a top portion of each spring; reinforcing nets are mounted among all the connecting bases, and the peripheries of the reinforcing nets are close to the peripheries of the first layer and the second layer.

Claims (8)

1. A high-elastic anti-deformation mattress, comprising a mattress assembly ( 1 ) which includes a first layer ( 2 ), a second layer ( 3 ) and a third layer ( 4 ) from top to bottom in a sequence, wherein a plurality of assembling chambers ( 8 ) are formed in the second layer ( 3 ), and each assembling chamber ( 8 ) is filled with a spring ( 5 ); a top end of each spring ( 5 ) is upward towards a top portion of the corresponding assembling chamber ( 8 ), and a bottom end of each spring ( 5 ) is downwards connected to a top surface of the third layer ( 4 ); a connecting base ( 6 ) is inserted into each of the top end and the bottom end of each spring ( 5 ); reinforcing nets ( 7 ) are connected between all the connecting bases ( 6 ) on the top portion, and reinforcing nets ( 7 ) are also connected between all the connecting bases ( 6 ) at the bottom portion; an elastic insertion rod ( 10 ) is connected between each upper connecting base and the corresponding lower connecting base ( 6 ); the elastic insertion rods ( 10 ) downwards wrap the springs ( 5 ) from the top ends to the bottom ends; each assembling chamber ( 8 ) is filled with a tubular independent packaging cushion ( 11 ); the springs ( 5 ) wrapped with the elastic insertion rods ( 10 ) are jointly embedded into the independent packaging cushions ( 11 ); outer circular surfaces of the independent packaging cushions ( 11 ) are tightly attached to chamber surfaces of the plurality of assembling chambers ( 8 ); and the springs ( 5 ) and the outer circular surfaces of the independent packaging cushions ( 11 ) are tightly attached to the chamber surfaces of the independent packaging cushions ( 11 ).

2. The high-elastic anti-deformation mattress according to claim 1 , wherein the first layer ( 2 ), the second layer ( 3 ) and the third layer ( 4 ) are all filled with a mixture of rebound memory foam, sponge and latex as flexible fillers; the first layer ( 2 ), the second layer ( 3 ) and the third layer ( 4 ) are connected in a sewing mode; the independent packaging cushions ( 11 ) and the elastic insertion rods ( 10 ) are made of high-density latex; and the elastic insertion rods ( 10 ) are filled with the springs ( 5 ).

3. The high-elastic anti-deformation mattress according to claim 2 , wherein bottom ends of the independent packaging cushions ( 11 ) reach the top surface of the third layer ( 4 ), and top ends of the independent packaging cushions ( 11 ) reach a top surface of the second layer ( 3 ).

4. The high-elastic anti-deformation mattress according to claim 3 , wherein the springs ( 5 ) are made of alloy steel, and surfaces of the springs ( 5 ) are electroplated.

5. The high-elastic anti-deformation mattress according to claim 4 , wherein the second layer ( 3 ) is of a multi-layer structure formed by overlapping a plurality of first unit layers ( 31 ) and a plurality of second unit layers ( 32 ); the first unit layers ( 31 ) are filled with a mixture of latex and sponge, the second unit layers ( 32 ) are filled with high-density coconut fibers, and the second unit layers ( 32 ) are located on bottom layers of the first unit layers ( 31 ); top ends of the plurality of assembling chambers ( 8 ) downwards penetrate through top portions of the first unit layers ( 31 ), and bottom ends of the plurality of assembling chambers ( 8 ) downwards penetrate through bottom portions of the second unit layers ( 32 ); and the plurality of assembling chambers ( 8 ) are formed in the first unit layers ( 31 ) and the plurality of second unit layers ( 32 ) in a matrix mode.

6. The high-elastic anti-deformation mattress according to claim 5 , wherein the third layer ( 4 ) is filled with fibers.

7. The high-elastic anti-deformation mattress according to claim 6 , wherein wavy spring wires ( 12 ) are arranged on four edges of the mattress assembly ( 1 ), high points of wavy shape of the wavy spring wires ( 12 ) are connected to a bottom surface of the first layer ( 2 ), and bottom points of the wavy shape of the wavy spring wires ( 12 ) are connected to the third layer ( 4 ).

8. The high-elastic anti-deformation mattress according to claim 6 , wherein the first layer ( 2 ), the second layer ( 3 ) and the third layer ( 4 ) are jointly sleeved with anti-skid and wear-resistant backing fabric, the backing fabric is a mite-proof fabric, and air holes are formed in the backing fabric.
