[0001] The utility model relates to a medical aid, especially a soft and hard partition bed. BACKGROUND

[0002] In clinical medicine, the comfort degree of the bed will affect the rest state of the patient, and further affect the recovery of the patient. The bed comprises a bed frame and a mattress. The internal structure of the current mattress is usually fixed filling. The support force provided by the people during use is single, and the softness and hardness cannot be adjusted, which leads to poor sleep during hospitalization, affects the treatment effect, especially for patients in the psychiatric department. For example, different patients have different requirements for the support force of the mattress when using the sick bed. In order to meet the use needs, some mattresses that can be inflated and deflated appear on the market. The size of the support force is changed by adjusting the air pressure, but the support force provided by the mattress of this type is small in the different positions, and different support forces cannot be provided in different positions to meet the use needs of patients with different body types. Therefore, there is an urgent need for a bed that can adjust the softness and hardness of different positions on the mattress. SUMMARY

[0003] The utility model aims at providing a soft and hard partition bed to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is as follows:

[0005] A soft and hard partition bed comprises a bed frame, an adjusting unit, and a mattress. The bed frame is provided with a hole on the top side. The adjusting unit comprises a tensioning roller, a transition roller, a support belt, and a top pressing assembly. The tensioning roller and the transition roller are connected to the bed frame respectively. The tensioning roller is arranged on the left and right sides of the hole. The transition roller is located below the tensioning roller. The support belt is wound outside the transition roller and the two tensioning rollers. The top side of the support belt is not lower than the top side of the bed frame. The top pressing assembly has a top pressing roller abutting to one side of the support belt. The top pressing roller can reciprocate along the straight line direction and make the support belt tensioned or relaxed. The adjusting unit is arranged in the front and back directions. The mattress is located on the top side of the support belt.

[0006] The technical scheme has at least the following beneficial effects: the top side of the bed frame is provided with a hole through which the support belt protrudes, for each adjusting unit, the support belt is stretched by the transition roller and the tensioning roller, and the support belt is lifted by two tensioning rollers on the left and right sides of the hole, and the pressing roller in the pressing assembly abuts against the outer side of the support belt to adjust the tightness of the support belt, at this time, the mattress is lifted by the support belts of the plurality of adjusting units, the user lies on the mattress, the middle part of the mattress is concave, and the plurality of support belts provide the main support force, when the support force at different positions needs to be adjusted according to the body shape of the patient or the medical activity, the adjusting unit at the position is adjusted, specifically, the pressing roller in the pressing assembly is pressed towards the support belt to increase the pressure on the support belt, at this time, the support force is tightened to provide a harder support force at the position of the mattress, or the pressing roller in the pressing assembly is moved away from the support belt to reduce the pressure on the support belt, at this time, the support force is gradually relaxed to provide a softer support force at the position of the mattress, so that the plurality of adjusting units form a plurality of different partitions on the bottom side of the mattress, and the tightness of the support belts corresponding to different regions of the mattress can be adjusted according to different use needs, so that the support force provided by different regions of the mattress can be adjusted, greatly improving the flexibility and applicability during use.

[0007] As a further improvement of the above technical scheme, the left and right sides of the bottom of the bed frame are respectively provided with the transition rollers, and the support belt is wound outside the two transition rollers and the two tensioning rollers. The two transition rollers stretch the support belt to the left and right sides at the position of the bottom of the bed frame, so that the travel of the pressing roller towards the support belt when pressing the support belt can be further increased, so that the range of adjusting the tightness of the support belt can be increased, and the use experience can be further improved.

[0008] As a further improvement of the above technical scheme, the pressing assembly has two pressing rollers, and the two pressing rollers abut against the left and right sides of the support belt. When the tightness of the support belt needs to be adjusted, the two pressing rollers act on the left and right sides of the support belt at the same time, for example, when the support belt needs to be further tightened, the two pressing rollers move towards each other to press the left and right sides of the support belt inward, and when the support belt needs to be relaxed, the two pressing rollers move away from each other to relax the left and right sides of the support belt outward, so that when the tightness of the support belt is adjusted, the position of the support belt between the two tensioning rollers moves synchronously, which can reduce the problem of excessive wear of the support belt caused by unilateral stress.

[0009] As a further improvement of the above technical solution, the top pressing assembly comprises a bidirectional movable screw rod and a slide, the bidirectional movable screw rod is connected to the bottom side of the slide, the bidirectional movable screw rod is drivingly connected to two slides, the bidirectional movable screw rod can drive the two slides to move closer to or away from each other in the left-right direction, and two top pressing rollers are respectively rotationally connected to the two slides. The bidirectional movable screw rod provides driving force for the two top pressing rollers to move closer to or away from each other through the two slides, when it is necessary to further tension the support belt, the bidirectional movable screw rod drives the two slides to move closer to each other, so that the top pressing rollers on the two slides further press the left and right sides of the support belt; when it is necessary to relax the support belt, the bidirectional movable screw rod drives the two slides to move away from each other, so that the top pressing rollers on the two slides reduce the pressure on the left and right sides of the support belt.

[0010] As a further improvement of the above technical solution, the support belt is provided with a plurality of support belts in the front-rear direction. The provision of multiple support belts in the same adjusting unit in the front-rear direction can reduce the production and maintenance cost of the support belt, and further improve the overall practicability.

[0011] As a further improvement of the above technical solution, the outer side of the tensioning roller is formed with an annular protruding rib, a plurality of annular protruding ribs are arranged axially spaced apart on the tensioning roller, a limiting area is formed between adjacent two annular protruding ribs, and a plurality of support belts are arranged around the plurality of limiting areas. The plurality of annular protruding ribs form a protruding limiting structure on the outer side of the tensioning roller, which can limit the front and rear sides of the support belt respectively, effectively prevent the plurality of support belts from slipping axially along the tensioning roller during use, and improve the overall use stability.

[0012] As a further improvement of the above technical solution, the bed frame is provided with a limiting side on the left and right sides of the mattress respectively. The limiting side on the left and right sides of the bed frame can limit the left and right sides of the mattress, which can facilitate the quick loading of the mattress on the bed frame, and effectively prevent the mattress from being deviated left and right due to friction with the support belt during use, thereby improving the overall use stability.

[0013] As a further improvement of the above technical solution, a smooth layer is arranged on the bottom side of the mattress. When the tension of the support belt is adjusted, the support belt and the smooth layer on the bottom side of the mattress slide relative to each other. Since the friction between the smooth layer and the support belt is small, the pulling damage to the support belt is reduced, and the relative sliding of the support belt on the bottom side of the mattress is smoother.

[0014] As a further improvement of the above technical solution, the two tensioning rollers are respectively rotationally connected to the bed frame along the rotation axes in the front-rear direction. The two tensioning rollers can rotate on the bed frame, and when the tension of the support belt is adjusted, the support belt can drive the tensioning rollers to rotate, which can reduce the friction of the support belt at the position of the tensioning rollers, and is conducive to prolonging the service life of the support belt.

[0015] As a further improvement of the above technical solution, a pressure sensor is embedded in the position of the top pressing roller opposite to the support belt. When the top pressing roller is outside the support belt, the pressure sensor embedded in the outside of the top pressing roller can monitor the pressure applied to the support belt, thereby monitoring the tensioning force applied to the support belt, and improving the convenience of adjusting the softness and hardness of the support force.

[0024] Refer to Figure 1 With Figure 2 A soft and hard partition bed, comprising a bed frame 100, an adjusting unit and a mattress 300, wherein the top side of the bed frame 100 is provided with an opening; the adjusting unit comprises a tensioning roller 210, a transition roller 220, a supporting belt 230 and a top pressing assembly, the tensioning roller 210 and the transition roller 220 are connected to the bed frame 100 respectively, the left and right sides of the opening are respectively provided with the tensioning roller 210, the transition roller 220 is located below the tensioning roller 210, the supporting belt 230 is wound outside the transition roller 220 and the two tensioning rollers 210, the horizontal plane where the top side of the supporting belt 230 is located is not lower than the horizontal plane where the top side of the bed frame 100 is located, preferably, the horizontal plane where the top side of the supporting belt 230 is located is flush with the horizontal plane where the top side of the bed frame 100 is located, the top pressing assembly has a top pressing roller 241 abutting one side of the supporting belt 230, the top pressing roller 241 can reciprocate in a straight line direction and make the supporting belt 230 tensioned or relaxed, the adjusting unit is provided with a plurality of in front and back directions; the mattress 300 is located on the top side of the plurality of supporting belts 230, of course, in order to better feel the soft and hard degree of the supporting force provided by the supporting belt 230 to the mattress 300, the thickness of the mattress 300 is selected to be relatively thin, for example, between 3cm and 8cm, so as to avoid that the thickness of the mattress 300 is too large and the soft and hard degree of the supporting of the supporting belt 230 to the mattress 300 cannot be felt.

[0025] As can be seen from the above, the top side of the bed frame 100 is provided with a hole through which the support belt 230 protrudes. For each adjusting unit, the support belt 230 is stretched by the transition roller 220 and the tensioning roller 210, and is lifted by two tensioning rollers 210 on the left and right sides of the hole, respectively. The top pressing roller 241 in the top pressing assembly abuts the outer side of the support belt 230, and is used to adjust the tightness of the support belt 230. At this time, the mattress 300 is lifted by the support belt 230 of the plurality of adjusting units, and the user lies on the mattress 300. The middle part of the mattress 300 is concave, and the main support force is provided by the plurality of support belts 230. When it is necessary to adjust the support force at different positions according to the body type of the patient or the medical activity, the adjusting unit at the position is adjusted. Specifically, the top pressing roller 241 in the top pressing assembly is pressed towards the support belt 230, thereby increasing the pressure on the support belt 230. At this time, the support force is tightened, and a harder support force is provided for the position of the mattress 300. Alternatively, the top pressing roller 241 in the top pressing assembly is moved away from the support belt 230, thereby reducing the pressure on the support belt 230. At this time, the support force is gradually relaxed, and a softer support force is provided for the position of the mattress 300. In this way, a plurality of different partitions are formed on the bottom side of the mattress 300 by a plurality of adjusting units. The tightness of the support belt 230 corresponding to different regions of the mattress 300 can be adjusted according to different use needs, thereby adjusting the support force provided by different regions of the mattress 300, and greatly improving the flexibility and applicability during use. For example, a soft and hard support can be provided at the corresponding position for users of different body types, or the support force at different positions of the user can be adjusted according to different medical operation needs. For example, when a pad is needed to be placed in the waist position of the patient, the support force at the waist position of the patient can be reduced.

[0026] When the number of transition rollers 220 is one, the support belt 230 is connected at the head and tail after passing through the two tensioning rollers 210 and the transition roller 220, and rotates. However, the distance between the left and right sides of the support belt 230 is small at this time. When the support belt 230 is pressed inward on one side, the travel amount of the top pressing roller 241 is small. In order to increase the adjusting amount of the support belt 230, in the present embodiment, the left and right sides of the bottom of the bed frame 100 are respectively provided with the transition roller 220, and the support belt 230 is arranged outside the two transition rollers 220 and the two tensioning rollers 210. The two transition rollers 220 at the bottom of the bed frame 100 stretch the support belt 230 to the left and right sides, so that the travel of the top pressing roller 241 towards the support belt 230 can be further increased when the top pressing roller 241 presses the support belt 230. In this way, the range of adjusting the tightness of the support belt 230 can be increased, and the use experience can be further improved.

[0027] In the above embodiment, the top pressing roller 241 can be provided with only one, at this time, the top pressing roller 241 exerts force from the side of the support belt 230, the displacement amount of the support belt 230 relative to the mattress 300 is larger, and the wear between the support belt 230 and the mattress 300 is easy to speed up, so in this embodiment, the top pressing assembly has two top pressing rollers 241, and the two top pressing rollers 241 are respectively abutted on the left and right sides of the support belt 230. When it is necessary to adjust the tension of the support belt 230, the two top pressing rollers 241 act on the left and right sides of the support belt 230 at the same time, for example, when it is necessary to further tension the support belt 230, the two top pressing rollers 241 are close to each other, and the left and right sides of the support belt 230 are pressed inward; when it is necessary to relax the support belt 230, the two top pressing rollers 241 are away from each other, and the left and right sides of the support belt 230 are relaxed outward, so that when the tension of the support belt 230 is adjusted, the position of the support belt 230 between the two tensioning rollers 210 moves synchronously, which can reduce the problem of excessive wear of the support belt 230 due to unilateral stress.

[0028] The top pressing assembly is mainly used to drive the top pressing roller 241 to extrude the support belt 230 inward or move away outward, so as to adjust the tension of the support belt 230, and its structure form is various, for example, a cylinder or a hydraulic cylinder can be used as a driving source to drive the top pressing roller 241 to move, and in this embodiment, the top pressing assembly includes a bidirectional moving screw 242 and a sliding frame 243, the bidirectional moving screw 242 is connected to the bottom side of the sliding frame 243, the bidirectional moving screw 242 drives and connects the two sliding frames 243, the bidirectional moving screw 242 can drive the two sliding frames 243 to move close to or away from each other in the left and right directions, and the two top pressing rollers 241 are respectively rotationally connected to the two sliding frames 243. In actual application, the bidirectional moving screw 242 includes a sliding seat, a screw, a motor and a sliding block, the screw is rotationally connected to the sliding seat along the axis in the left and right directions, the screw has two thread segments with opposite thread directions, the sliding seat is connected with two sliding blocks, the two sliding blocks are threadedly connected to the two thread segments, and the motor is connected to the sliding seat and drives the screw, so that the motor can drive the screw to rotate, thereby driving the two sliding blocks to move close to or away from each other, and at this time, the two sliding frames 243 are connected to the two sliding blocks. The bidirectional moving screw 242 drives the two top pressing rollers 241 to move close to or away from each other through the two sliding frames 243, when it is necessary to further tension the support belt 230, the bidirectional moving screw 242 drives the two sliding frames 243 to move close to each other, so that the top pressing rollers 241 on the two sliding frames 243 further extrude the left and right sides of the support belt 230; when it is necessary to relax the support belt 230, the bidirectional moving screw 242 drives the two sliding frames 243 to move away from each other, so that the top pressing rollers 241 on the two sliding frames 243 reduce the pressure on the left and right sides of the support belt 230.

[0029] In the same adjustment unit, the number of support belts 230 can be only one, at this time, the support belt 230 covers a larger area in the front-rear direction, when the support belt 230 is partially damaged, the entire support belt 230 needs to be replaced, the maintenance cost is higher, therefore, in the embodiment, the support belt 230 is provided with a plurality of support belts 230 in the front-rear direction. The plurality of support belts 230 are provided in the front-rear direction in the same adjustment unit, which can reduce the production and maintenance cost of the support belt 230, and further improve the overall practicability.

[0030] In order to better limit the plurality of support belts 230 on the tensioning roller 210, in the embodiment, the outer side of the tensioning roller 210 is formed with a plurality of annular ribs 211, the annular ribs 211 are arranged at intervals in the axial direction of the tensioning roller 210, a limiting area is formed between the adjacent two annular ribs 211, and the plurality of support belts 230 are arranged around the plurality of limiting areas respectively. The plurality of annular ribs 211 form a protruding limiting structure on the outer side of the tensioning roller 210, which can limit the front and rear sides of the support belt 230 respectively, effectively prevent the plurality of support belts 230 from slipping in the axial direction of the tensioning roller 210 during use, and improve the overall use stability.

[0031] In order to improve the stability of installing and placing the mattress 300, in the embodiment, the bed frame 100 is provided with a limiting rib 110 on the left and right sides of the mattress 300 respectively. The limiting ribs 110 on the left and right sides of the bed frame 100 can limit the left and right sides of the mattress 300, which can facilitate the quick loading of the mattress 300 on the bed frame 100, and effectively prevent the mattress 300 from being driven to shift left and right due to friction with the support belt 230 during use, thereby improving the overall use stability.

[0032] In some embodiments, the bottom side of the mattress 300 is provided with a smooth layer, the smooth layer is made of a material with small friction, for example, silk, synthetic fiber cloth, etc., and a layer is compounded on the bottom side of the mattress 300. When adjusting the tightness of the support belt 230, the support belt 230 and the smooth layer on the bottom side of the mattress 300 slide relative to each other, and the friction between the smooth layer and the support belt 230 is small, which reduces the pulling damage to the support belt 230, so that the support belt 230 slides more smoothly on the bottom side of the mattress 300.

[0033] In order to reduce the friction when the support belt 230 moves relative to the tensioning roller 210, in the embodiment, the two tensioning rollers 210 are rotatably connected to the bed frame 100 along the rotation axes extending in the front-rear direction. In actual application, the transition roller 220 can also be rotatably connected to the bottom of the bed frame 100, and the rotation axis of the transition roller 220 extends in the front-rear direction. Similarly, the top pressing roller 241 can also be rotatably connected to the slide frame 243, and the rotation axis of the top pressing roller 241 extends in the front-rear direction. The two tensioning rollers 210 can rotate on the bed frame 100. When the tension of the support belt 230 is adjusted, the support belt 230 can drive the tensioning roller 210 to rotate, so as to reduce the friction of the support belt 230 at the position of the tensioning roller 210, and facilitate the extension of the service life of the support belt 230.

[0034] In some embodiments, the position of the top pressing roller 241 opposite to the support belt 230 is embedded with a pressure sensor. When the top pressing roller 241 presses the support belt 230 from the outside, the pressure sensor embedded on the outside of the top pressing roller 241 can monitor the pressure applied to the support belt 230, so as to monitor the tension applied to the support belt 230, and improve the convenience of adjusting the softness and hardness of the support force.

[0035] The preferred embodiments of the utility model are described above, but the present application is not limited to the above-mentioned embodiments.
