Referring to fig. 1, the hardness-adjustable mattress disclosed by the invention comprises an upper cushion 1 and a lower cushion 2, wherein the upper cushion 1 is a flexible cushion and is thin, and the periphery of the upper cushion 1 can be covered with a protective cover (not shown in the figure) made of a TPU and PVC blended modified composite fabric; the lower mattress 2 comprises a rigid frame 21 and a hardness adjusting assembly 3 arranged in the rigid frame 21, and an operator can adjust the hardness of the lower mattress 2 by controlling the hardness adjusting assembly 3, so that the hardness of the whole mattress can be changed more conveniently.

Referring to fig. 1 and 2, the mattress comprises four adjusting regions 4, the four adjusting regions 4 are sequentially arranged along the width direction of the lower mattress 2, a group of hardness adjusting assemblies 3 are arranged in each adjusting region 4, and the hardness adjusting assemblies 3 can adjust the hardness in the corresponding adjusting regions 4. When the mattress is used by one person, the user can adjust the hardness of all the adjusting areas 4 to be the same, so that the use comfort is improved; when the mattress is used by two persons and the two persons have different requirements on hardness, the four adjusting areas 4 can be divided into two groups and respectively used by the two persons; when the mattress is used by three people, for example, a small baby is added to a couple, two regulating areas 4 in the middle can be combined into one for the small baby, and the other two can be used by the couple respectively. Through the arrangement, members with different hardness requirements can be used simultaneously, so that the applicability is greatly improved.

The single group hardness adjusting assembly 3 comprises a plurality of elastic supporting sheets 31, a linear traction piece 32 and four guide wheels 33, the elastic supporting sheets 31 can be made of materials with weaker elasticity such as latex, the elastic supporting sheets 31 are linearly arranged along the long side direction of the lower cushion 2, a hard rod 34 is fixedly arranged at the lower end of each elastic supporting sheet 31 in a penetrating mode, and the hard rods 34 are rotatably connected in the rigid frame 21, so that the elastic supporting sheets 31 can be circumferentially turned around the hard rods 34, and the rotating axis of the elastic supporting sheets 31 is horizontally arranged and perpendicular to the long side direction of the lower cushion 2. The linear traction piece 32 is connected end to end and wound outside the four guide wheels 33, wherein the two guide wheels 33 are respectively positioned at the two ends of the rigid frame 21 along the long side direction of the lower cushion 2, all the elastic support pieces 31 are positioned between the two guide wheels 33, and the linear traction piece 32 penetrates through the upper end of each elastic support piece 31 and is fixed with the elastic support pieces 31 through glue; a positioning component 5 is arranged on one side of the rigid frame 21, and the positioning component 5 is used for limiting the movement of the linear drawing piece 32 along the drawing direction thereof; the hardness adjusting assembly 3 further comprises an inclined pad 22 fixed in the rigid frame 21, and one side of the inclined pad 22 is provided with an inclined supporting surface 23; the upper cushion 1 is partially embedded in the rigid frame 21 and supported at the upper ends of the elastic support pieces 31, and when the elastic support pieces 31 at the ends are obliquely turned and abut on the inclined support surfaces 23, the upper cushion 1 supported by the elastic support pieces 31 is in the lowest state.

The specific hardness adjusting mode of the lower cushion 2 is as follows: an operator pulls the linear traction piece 32 forward to drive all the elastic support pieces 31 to turn upwards and to be in a vertical state, at the moment, the upper cushion 1 is jacked up to the highest position, and the deformation allowance of the lower cushion 2 in the vertical direction is also in a maximum state, namely the whole mattress is in a state of optimal elasticity and minimum hardness; the operator can then limit the movement of linear pull 32 by positioning assembly 5, thereby maintaining elastic support sheet 31 in an upright position.

When an operator needs to improve the hardness of the mattress, the linear traction member 32 can be pulled reversely to enable all the elastic support sheets 31 to turn downwards synchronously until the elastic support sheet 31 at the outermost edge abuts against the inclined support surface 23 of the inclined cushion block 22 and stops the traction, at this time, the upper cushion 1 is jacked up to the lowest position, and the deformation allowance of the lower cushion 2 along the vertical direction is also in the minimum state, namely, the whole mattress is in the state of the weakest elasticity and the maximum hardness.

Referring to fig. 2 and 3, the positioning assembly 5 includes two positioning rings 51 fixed on one side of the rigid frame 21, and an operating rod 52 fixedly connected to the linear traction member 32, the operating rod 52 is hollow, a sub-rod 53 is slidably inserted into each of two ends of the operating rod 52, and the sub-rods 53 are coaxial with the operating rod 52; the line connecting the two positioning rings 51 is parallel or coaxial to the axis of the operating rod 52.

A wedge-shaped block 54 is arranged in the operating rod 52, two obliquely arranged guide surfaces are arranged at two ends of the wedge-shaped block 54 along the axial direction of the operating rod 52, an obliquely arranged guide auxiliary surface is arranged at one end of the sub-rod 53 extending into the operating rod 52, the guide auxiliary surface abuts against the guide surface, an elastic part 55 is further arranged in the operating rod 52, the elastic part 55 is a spring and is used for applying thrust to the wedge-shaped block 54 to drive the guide surface to abut against the guide auxiliary surface, so that the two sub-rods 53 are driven to oppositely move and extend into the nearby positioning ring 51, and finally, the positioning is completed and the movement of the linear traction part 32 is limited; an operating block 56 is embedded on the peripheral wall of the operating rod 52 in a sliding manner, one end of the operating block 56 penetrates into the operating rod 52 and abuts against the wedge block 54, the operating block 56 has the tendency of applying reverse thrust to the wedge block 54 to drive the guide surface to be separated from the guide auxiliary surface, two contracting and pulling pieces 57 are connected between the two sub-rods 53, and the contracting and pulling pieces 57 are elastic pull ropes; when the operator presses the operating block 56, the sub-rods 53 gradually lose the pushing force of the wedge blocks 54, the two sub-rods 53 move toward each other, and the ends of the sub-rods 53 are disengaged from the positioning ring 51.

The implementation principle of the embodiment is as follows: the operator can push the operating block 56 to retract the two sub-rods 53 for a certain distance, and pull the linear pulling member 32 forward to turn all the elastic supporting pieces 31 to be vertical, at this time, the operating rod 52 is coaxial with the positioning ring 51, the operator removes the pressure on the operating block 56, and the two sub-rods 53 are pushed outwards and penetrate into the positioning ring 51 to complete the positioning. The mattress in this state has better expansion margin along the vertical direction, namely the hardness of the mattress is less.

On the contrary, if the operator needs to increase the hardness of the mattress, the operator presses the operation block 56 to separate the sub-rod 53 from the positioning ring 51 and pulls the linear pulling member 32 in the opposite direction to turn the elastic support piece 31 to the inclined state, so that the vertical expansion amount of the lower mattress 2 in this state becomes smaller and the hardness of the mattress becomes larger.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
