And the sponge cover 120 is sewn with the edge of the sponge layer 110, namely, the sponge cover is respectively wrapped between the spiral assemblies 400 and on the periphery of the spiral assemblies 400. Thereby providing protection for the screw assemblies 400 and reducing friction between the screw assemblies 400, thereby reducing noise.

Referring to fig. 2 and 3, the screw assembly 400 includes a first screw part 410 and a second screw part 420, and the first screw part 410 is disposed opposite to the second screw part 420. That is, the first spiral portion 410 and the second spiral portion are disposed so as to extend in parallel in the same direction and parallel to each other in the longitudinal direction. And the first spiral part 410 and the second spiral part 420 are mutually wound, that is, the first spiral part 410 and the second spiral part 420 are alternately wound together at the side protruding part. And the first screw part 410 and the second screw part 420 are integrally provided, the screw assembly 400 is formed by bending a steel wire, that is, the steel wire is bent and knotted at one end to form the first screw part 410, and then the top end or the bottom end of the first screw part 410 horizontally extends and is bent and hit to form the second screw part 420.

By utilizing the mutual winding between the first screw part 410 and the second screw part 420, the connectivity between the whole screw assembly 400 is improved, and the stability of the screw assembly 400 in the use process is ensured.

The bed body 100 includes a plurality of spiral assemblies 400, and the plurality of spiral assemblies 400 are sequentially arranged along a direction perpendicular to an extension direction of the spiral assemblies 400 to form a spiral member with a certain length. The length specification can be set and manufactured according to the width or length of the bed 100. The second helical portion 420 of the adjacent two helical assemblies 400 is intertwined with the first helix, e.g., the second helical portion 420 of the first helical assembly 400 is intertwined with the first helix. Thereby increasing connectivity between adjacent screw assemblies 400.

The bed 100 is formed by sequentially arranging a plurality of screw members in a direction perpendicular to the length extension direction thereof, wherein the first screw portion 410 and the second screw portion 420 between the adjacent screw members are intertwined. And the two screw assemblies 400 are connected to each other to realize the integral manufacture of one steel wire. Therefore, in the process that the bed body 100 bears the pressure, the pressure of the spiral component 400 can be uniformly dispersed, so that the stability of the bed body 100, the spiral component 400 and the springs is improved, and the mute and noise reduction effects of the springs are improved, so that the bed body 100 and the spiral component 400 have strong support.

Referring to fig. 2 and 3, a first C-ring 310 is provided on the first screw part 410, and a second C-ring 340 is provided on the second screw part 420. The first C-ring 310 is disposed at the top end of the first spiral portion 410, and the second C-ring 340 is also disposed at the top end of the second spiral portion 420. And the protrusions of the first and second C-rings 310 and 340 are disposed away from each other. The top end of the first C-shaped ring 310 and the top end of the second C-shaped ring 340 are mutually wound, that is, the top end inner wall of the first C-shaped ring 310 and the top end inner wall of the second C-shaped ring 340 are mutually abutted.

When the first spiral part 410 and the second spiral part 420 are pressed, the contact part of the first C-shaped ring 310 and the second C-shaped ring 340 moves in a direction deviating from each other, so that the pressing noise of the first C-shaped ring 310 and the second C-shaped ring 340 and the steel wires of the first C-shaped ring and the second C-shaped ring are reduced.

In the screw assembly 400, the top end of the first C-ring 310 is connected to the top end of the second C-ring 340 of the second screw 420 adjacent thereto. The second C-shaped tip is connected to the tip of the first C-shaped ring 310 of the first spiral portion 410 adjacent thereto. And the supporting force of the spring is lifted by the mutually abutting crossing points.

Referring to fig. 2 and 3, a first raised ring 320 is further provided on the first screw part 410, and a second raised ring 350 is further provided on the second screw part 420. One end of the first protrusion ring 320 is connected to the bottom end of the first C-shaped ring 310, and the other end of the first protrusion ring 320 extends toward the bottom of the first screw part 410 after being rotated and knotted from the middle thereof. One end of the second protrusion ring 350 is connected to the bottom end of the second C-shaped ring 340, and the other end of the second protrusion ring 350 is rotated at the middle thereof to be knotted and then extended toward the bottom end of the second screw part 420.

An accommodating space 430 is provided between the first raised ring 320 and the second raised ring 350, and the accommodating space 430 is disposed right below the connection point of the first C-shaped ring 310 and the second C-shaped ring 340. Therefore, in the process of compression of the first C-shaped ring 310 and the second C-shaped ring 340, the first C-shaped ring 310 and the second C-shaped ring 340 compress toward the accommodating space 430, thereby further reducing friction and extrusion between the steel wires made of spring materials and reducing noise generated by friction.

The first screw part 410 is further provided with a first bottom ring 330 and the second screw part 420 is further provided with a second bottom ring 360. One end of the first bottom ring 330 is fixedly connected to the bottom end of the first raised ring 320. One end of the second bottom ring 360 is fixedly coupled to the bottom end of the second raised ring 350. The other end of the first bottom ring 330 is fixedly connected with the other end of the second bottom ring 360 and horizontally disposed. I.e., the connection point of the first bottom ring 330 and the first raised ring 320 is rotatably extended toward the connection point of the second bottom ring 360 and the second raised ring 350.

Wherein the distance between the connection point of the first bottom ring 330 and the first raised ring 320 and the connection point of the second bottom ring 360 and the second raised ring 350 is greater than the distance between the first C-ring 310 and the second C-ring 340. The distance between the first bottom ring 330 and first raised ring 320 connection point and the second bottom ring 360 and second raised ring 350 connection point is less than the distance between the first raised ring 320 and second raised ring 350. The distance between the first bottom ring 330 and first raised ring 320 connection point and the second bottom ring 360 and second raised ring 350 connection point is less than the distance between the first raised ring 320 and second raised ring 350.

Therefore, when the top end or the bottom end of the screw assembly 400 is under pressure, the first C-shaped ring 310, the second C-shaped ring 340, the first bottom ring 330 and the second bottom ring 360 can move into the accommodating space 430, so that friction noise between the steel wires made of the spring material can be reduced.

As shown with reference to figures 2 and 3,

the bed body 100 not only includes spiral members arranged in a stacked manner, i.e., two layers of spiral members, but also includes a spiral assembly 400 disposed in opposite abutment with the spiral assembly 400. And the sponge layer 110 is arranged between the mutually abutted spiral members, so that the direct contact between the steel wires made of the spring material is reduced, and the occurrence of noise is reduced.

The abutting spiral assembly 400 includes the first bottom rings 330 and the second bottom rings 360 of the two stacked spiral assemblies 400 abutting each other, i.e., the two first C-shaped rings 310 and the second C-shaped ring 340 of the abutting spiral assembly 400 face to the outside of the bed body 100.

Since the distance between the connection point of the first bottom ring 330 and the first raised ring 320 and the connection point of the second bottom ring 360 and the second raised ring 350 is greater than the distance between the first C-ring 310 and the second C-ring 340. Therefore, when the first C-shaped ring 310 and the second C-shaped ring 340 face to the outside of the bed body 100, the stress points of the bed body 100 are smaller, and the support effect is stronger, so that the hardness of the bed body 100 is improved.

When the abutting screw assemblies 400 include the first C-shaped ring 310 and the second C-shaped ring 340 of the two stacked screw assemblies 400, the first bottom ring 330 and the second bottom ring 360 of the abutting screw assemblies 400 abut each other, i.e., face the outside of the bed 100.

Since the distance between the connection point of the first bottom ring 330 and the first raised ring 320 and the connection point of the second bottom ring 360 and the second raised ring 350 is greater than the distance between the first C-ring 310 and the second C-ring 340. Therefore, the surface of the bed body 100 can better reflect the elasticity, promote the recovery capacity, rationalize the whole structure of the bed body 100 and increase the softness.

Referring to fig. 1, the protection frame 200 is an M-shaped protection frame 200, and the M-shaped protection frame 200 includes a V-shaped rotation part 220 and extension parts 230 fixedly connected to both ends of the rotation part 220. The rotary ring 210 is provided at the center of the rotary part 220, and both ends of the rotary part 220 extend toward the rotary ring 210 and are fixedly connected along the ring rotation. The two extending portions 230 are horizontally disposed, and the two extending portions 230 are fixedly connected with the top edge and the bottom edge of the bed body 100 respectively.

Therefore, the edge collapse is effectively protected, and the edge is not slipped when a user sits on the seat for supporting and reinforcing. The rotary ring 210 can realize pressure separation, and the middle part reinforced by the M-shaped protection frame 200 is not obviously deformed under normal stress under the condition that the spring can bear the load and the two sides are supported.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
