Description

Technical Field

[0001] The invention relates to the technical field of sweat steaming equipment, and in particular to an adjustable bed and a three-purpose sweat steaming room with the adjustable bed. Background Art

[0002] A steam room, also known as a sauna room, provides physical therapy to the human body by generating steam or infrared rays, negative ions and other substances to speed up blood circulation and metabolism, and supply sufficient nutrition and oxygen to tissues and organs throughout the body, thereby improving the functions of tissues and organs, and enabling the body to quickly eliminate fatigue and restore physical strength.

[0003] However, the interior layout of a traditional steam room is relatively simple. When people take a steam bath in the steam room, they mainly lie on a recliner or sit quietly on a chair. It has the disadvantages of simple structure and relatively single function. Bathers often need to change chairs to change their bathing posture. In this way, multiple chairs are often needed in the steam room to meet the needs of bathing. The increase in the number of chairs not only occupies more space in the steam room, making the activity area in the steam room narrower, but also has a higher cost.

[0004] The existing Chinese patent with publication number CN109779325A discloses a retractable steam room with both sitting and lying positions, including a steam room body, an infrared heating element and a control panel arranged in the steam room, a slide rail is arranged on the bottom plate of the steam room body, a mobile box is arranged in the front of the steam room body, the mobile box is slid on the slide rail, a seat is arranged on the bottom plate, and the backrest of the seat can be adjusted at an angle. When in use, the human body can sit or lie on the seat at different inclination angles, and at the same time, the mobile box can move forward and backward through the steam room body to achieve the effect of adjusting the space under the steam room body to meet the different sitting or lying positions of the human body; the mobile box can be retracted when the steam room is not in use to save space; and when sitting in a steam room, the mobile box is retracted inwards and used as an office and entertainment platform.

[0005] However, the above-mentioned sweat steaming room has the following disadvantages: it only has the functions of lying and sitting, and the user cannot lie down when using it, and cannot achieve the effect of complete relaxation. Summary of the invention

[0006] The purpose of the present invention is to provide an adjustable bed, which is easy to adjust and has multiple uses. Another purpose of the present invention is to provide a three-purpose steaming room with an adjustable bed, which can be used in lying, supine and sitting positions, and has a multifunctional effect.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: an adjustable bed, comprising a bed frame and a bed board arranged on the bed frame, the bed board comprising a middle board fixed to the bed frame and a front board and a rear board hinged at both ends of the middle board, and a rotating shaft is arranged on the bed frame for rotation;

[0008] A front hinged rod assembly is provided between the front plate and the bed frame, a rear hinged rod assembly is provided between the rear plate and the bed frame, a connecting rod is hinged between the front hinged rod assembly and the rear hinged rod assembly, the front hinged rod assembly drives the front plate to flip relative to the middle plate, and the rear hinged rod assembly drives the rear plate to flip relative to the middle plate;

The rotation of the rotating shaft causes the driving rod to move relative to the rotating shaft to achieve unlocking. The driving rod is hinged to the end of the front hinged rod assembly to drive the front hinged rod assembly from a supporting state to a bending state, so that the driving rod can be unlocked relative to the rotating shaft, so that the front plate and the rear plate can be placed flat on the bed frame.

[0015] The present invention is further configured as follows: a driving assembly includes a pull rope and a seesaw, the seesaw is hinged to the bed frame, the pull rope is fixedly connected to the seesaw, and a push block is provided on the driving rod to cooperate with the push of the seesaw. When the pull rope pulls the seesaw to rise, the seesaw pushes the push block to unlock the driving rod relative to the rotating shaft, the front hinged rod assembly drives the front plate to lie flat, and the rear hinged rod assembly drives the rear plate to lie flat.

[0016] By adopting the above technical solution, the pull rope is pulled to make the seesaw tilt up. When the seesaw rests on the push block, the push block pushes the driving rod to rotate. At this time, with the push block as the fulcrum, the end of the driving rod hinged on the rotating shaft moves upward and drives the rotating shaft to rotate. The driving rod is hinged to the end of the front hinged rod assembly to drive the front hinged rod assembly from a supporting state to a bending state. In this way, the driving rod can be unlocked relative to the rotating shaft, so that the front plate and the rear plate can be placed flat on the bed frame.

[0017] The present invention is further configured as follows: the front hinged rod assembly comprises a front bottom rod hinged to the bed frame, a front top rod hinged to the front bottom rod, and the front top rod is hinged to the bottom surface of the front plate.

In this way, the adjustment is more labor-saving and convenient.

[0026] The present invention is further configured as follows: the rotating shaft includes a rotating block, the driving rod is hinged on the rotating block, and a connecting line is formed between the connection point A between the rotating block and the rotating shaft and the end B of the driving rod away from the rotating block. When the driving rod is locked relative to the rotating shaft, the hinge point C between the rotating block and the driving rod is located below the connecting line, and the inclination angle α of the driving rod relative to the ground is set to 15°-25°; when the driving rod is unlocked relative to the rotating shaft, the hinge point C between the rotating block and the driving rod is located above the connecting line.

[0027] By adopting the above technical solution, when the driving rod is in a locked state relative to the rotating shaft, that is, the hinge point C is located below the connecting line, at this time, the driving rod is deflected downward relative to the connecting line, so that the point of action of the driving rod on the rotating shaft is located below the rotating shaft, and the driving rod can support and lock the front hinged rod assembly.

[0028] Another object of the above-mentioned technology of the present invention is achieved through the following technical scheme: a three-purpose sweat steaming room with an adjustable bed, comprising a sweat steaming room body, an adjustable bed is arranged in the sweat steaming room body, and a footrest, a flip plate and a backrest are hingedly arranged on the inner wall of the sweat steaming room body; a support assembly is arranged on the inner wall of the sweat steaming room body, and the support assembly includes a fixed frame and a support block flipped and connected to the fixed frame; when the support block flips upward relative to the fixed frame, the top of the support block abuts against the flip plate, so that the flip plate is in a horizontal state, and when the support block flips downward relative to the fixed frame, the bottom surface of the flip plate abuts against the fixed frame, so that the flip plate is in a tilted downward state.

[0029] By adopting the above technical scheme, when the front plate and the rear plate of the adjustable bed are tilted up, the user can lie on his back on the bed plate. At this time, the flip block can be tilted and flipped downward to put the feet on the flip plate; when the front plate and the rear plate of the adjustable bed are flat, the user can lie flat or sit on the bed plate. When sitting on the bed plate, the backrest is flipped outward to be above the adjustable bed, the feet can be put on the footrest step and the back can be leaned on the backrest. The supporting block is flipped upward so that the supporting block is against the lower surface of the flip plate. The flip plate is in a horizontal state to form a table top, which can be used for writing, reading, etc. The use is more convenient and comfortable, and it has a multifunctional effect.

[0030] In summary, the present invention has the following beneficial effects:

[0031] 1. The front and rear boards are tilted relative to the bed frame, so the user can lie on the bed board with the upper body leaning against the front board, the buttocks sitting on the middle board, and the legs placed on the rear board, which is more comfortable to use; the rotating shaft drives the driving rod to move, so that the front and rear boards can be unlocked and turned over and laid flat on the bed frame, and the user can sit or lie flat on the bed board, so that one thing can be used for multiple purposes, and the adjustment process is also more convenient, and the structural design is more ingenious;

[0046] like Figure 1 and Figure 2As shown, a rotating shaft 3 is arranged in the middle of the lower part of the bed frame 1, and the rotating shaft 3 is rotatably connected to the bed frame 1. The rotating shaft 3 includes a rotating block 31 arranged on the side wall, and the end of the rotating block 31 away from the rotating shaft 3 is hinged with a driving rod 4. A front hinged rod assembly 11 is arranged between the front plate 22 and the bed frame 1, and a rear hinged rod assembly 12 is arranged between the rear plate 23 and the bed frame 1. The front hinged rod assembly 11 drives the front plate 22 to flip relative to the middle plate 21, and the rear hinged rod assembly 12 drives the rear plate 23 to flip relative to the middle plate 21 driven by the connecting rod 13; the front hinged rod assembly 11 includes two front bottom rods 111 hinged to the bed frame 1, and two front top rods 112 correspondingly hinged to the front bottom rods 111, and the upper ends of the two front top rods 112 are hinged to the bottom surface of the front plate 22, and the rear hinged rod assembly 12 includes two rear bottom rods 121 hinged to the bed frame 1, and two rear top rods 122 correspondingly hinged to the rear bottom rod 121, and the upper ends of the two rear top rods 122 are hinged to the bottom surface of the rear plate 23. A front connecting block 113 is provided between the two front top rods 112, a bottom rod connecting block 114 is provided between the two front bottom rods 111, a rear connecting block 123 is provided between the two rear top rods 122, the front end of the driving rod 4 is hinged to the center of the bottom rod connecting block 114, a connecting rod 13 is provided between the front connecting block 113 and the rear connecting block 123, the front end of the connecting rod 13 is hinged to the front connecting block 113, and the rear end of the connecting rod 13 is hinged to the rear connecting block 123.

[0047] When the front plate 22 and the rear plate 23 are placed flat on the bed frame 1, the front bottom rod 111 and the front top rod 112, as well as the rear bottom rod 121 and the rear top rod 122 are relatively in a bent state; when the front plate 22 and the rear plate 23 are tilted upward relative to the bed frame 1, the front bottom rod 111 and the front top rod 112, as well as the rear bottom rod 121 and the rear top rod 122 are relatively in a supporting state.

[0048] like Figure 1-3 As shown, a line is formed between the connection point A between the swivel block 31 and the rotating shaft 3 and the end B of the driving rod 4 away from the swivel block 31. When the driving rod 4 is locked relative to the rotating shaft 3, the hinge point C between the swivel block 31 and the driving rod 4 is located below the line, and the inclination angle α of the driving rod 4 relative to the ground is set to 20°; when the driving rod 4 is unlocked relative to the rotating shaft 3, the hinge point C between the swivel block 31 and the driving rod 4 is located above the line. When the driving rod 4 is in a locked state relative to the rotating shaft 3, that is, the hinge point C is located below the line, at this time, the driving rod 4 deflects downward relative to the line, so that the point of action of the driving rod 4 on the rotating shaft 3 is located below the rotating shaft 3, and the driving rod 4 can support and lock the front hinge rod assembly 11.

[0049] like Figure 1 and Figure 2As shown, a driving assembly is provided on the bed frame 1, and the driving assembly includes a pull rope 5 and a seesaw 51. One end of the seesaw 51 is hinged to the bed frame 1, and the pull rope 5 is fixedly connected to the other end of the seesaw 51. A winding rod 15 is provided on the bed frame 1. A hollow fixing sleeve 14 is provided on the side of the bed frame 1. A pull rod 141 is provided in the fixing sleeve 14. One end of the pull rope 5 is wound around the winding rod 15 and then fixedly connected to the lower end of the pull rod 141. The driving rod 4 is provided with a push block 41 which cooperates with the seesaw 51. When the pull rope 5 pulls the seesaw 51 upward, the seesaw 51 pushes the push block 41, and the push block 41 pushes the driving rod 4 to rotate to achieve unlocking. At this time, with the push block 41 as the fulcrum, the end of the driving rod 4 hinged to the rotating block 31 moves upward, the driving rod 4 moves backward as a whole, and drives the rotating shaft 3 to rotate in the clockwise direction. The end of the driving rod 4 hinged to the front connecting block 113 generates a pulling force on the front connecting block 113, driving the front hinged rod assembly 11 The supporting state is changed into the bending state, so that the driving rod 4 can be unlocked relative to the rotating shaft 3, and the rear hinge rod assembly 12 is driven to move to the bending state through the connecting rod 13, and the front top rod 112 and the rear top rod 122 respectively pull down the front plate 22 and the rear plate 23, so that the front plate 22 and the rear plate 23 are placed flat on the bed frame 1. Since the driving rod 4 is restrained by the rotating block 31, it will not change its state at will, and the human body lying on the bed board 2 exerts pressure on the bed board 2, so that the front plate 22 and the rear plate 23 will not warp up.

[0050] like Figure 2 As shown, a gas spring 6 is arranged between the bed frame 1 and the bottom surface of the front plate 22, the lower end of the gas spring 6 is hinged to the bed frame 1, and the upper end of the gas spring 6 is hinged to the bottom surface of the front plate 22. When the front plate 22 and the rear plate 23 are placed flat on the bed frame 1, the gas spring 6 is compressed, and when the outer end of the front plate 22 or the rear plate 23 is lifted to make it warp up, with the help of the gas spring 6, only a little force is needed to automatically lift the front plate 22 and the rear plate 23, so that the adjustment is more labor-saving and convenient.

[0051] The basic working principle of the present invention is as follows: during use, the pull rope 5 can be pulled to make the seesaw 51 tilt upward, and the push block 41 can be used to drive the rotating shaft 3 to rotate to achieve unlocking, and then the outer end of the front plate 22 or the rear plate 23 is pressed down, and the front plate 22 and the rear plate 23 are simultaneously turned downward relative to the middle plate 21 under the linkage of the connecting rod 13, until the lower bottom surface of the front plate 22 and the lower bottom surface of the rear plate 23 are in contact with the bed frame 1, at this time, the front hinge rod assembly 11 and the rear hinge rod assembly 12 are bent toward the middle of the bed frame 1, and the front plate 22, the middle plate 21 and the rear plate 23 are in the same plane, which can be used for the user to sit or lie flat, and the user can achieve complete relaxation; when the user needs to lie on his back, the outer end of the front plate 22 or the rear plate 23 is lifted up (due to The rear plate 23 protrudes relative to the bed frame 1, and it is more convenient to lift the rear plate 23). Under the linkage of the connecting rod 13, the front plate 22 and the rear plate 23 are simultaneously flipped upward relative to the middle plate 21, and the bed board 2 as a whole is in a state of being upturned at both ends and concave in the middle. At this time, the front hinged rod assembly 11 and the rear hinged rod assembly 12 are both in a supporting state, and the driving rod 4 is pulled to drive the rotating shaft 3 to rotate and is in a locked state relative to the rotating shaft 3, and the hinge point C is against the ground. In this way, when the user lies on his back on the bed board 2, the upper body leans on the front plate 22, the buttocks sit on the middle plate 21, and the legs are placed on the rear plate 23. It is more comfortable to use, can achieve the effect of one thing for multiple uses, and the adjustment process is also more convenient, and the structural design is more ingenious. In addition, the use of the pull rope 5 as a driving component has the effect of lower cost compared to the motor.

[0052] Embodiment 2:

[0053] An adjustable bed, such as Figure 4 and Figure 5As shown, the difference between this embodiment and the first embodiment is that: the driving assembly includes a lever 7 rotatably connected to the end of the rotating shaft 3, the lever 7 is axially limited on the rotating shaft 3 by a nut, and an arc block 32 is provided at the end of the rotating shaft 3 to abut against the lever 7, and a neutral position is formed between the arc block 32 and the end of the rotating shaft 3. A fixing block 16 is provided on the side of the bed frame 1, and a reset spring 71 is provided between the lever 7 and the fixing block 16, one end of the reset spring 71 is fixedly connected to the fixing block 16, and the other end of the reset spring 71 is fixedly connected to the side wall of the lever 7. Two limit blocks 17 are also provided on the side of the bed frame 1, and the limit blocks 17 are limitedly matched with the lever 7, and the limit blocks 17 include a first limit block 171 and a second limit block 172. When the lever 7 is moved, the lever 7 drives the rotating shaft 3 to rotate through the arc block 32, so that the driving rod 4 rotates relative to the rotating shaft 3 to achieve unlocking, and the front hinged rod assembly 11 drives the front plate 22 to be leveled, and the rear hinged rod assembly 12 drives the rear plate 23 to be leveled. When the lever 7 is released, since there is a gap between the arc block 32 and the end of the rotating shaft 3, the lever 7 moves along the gap under the tension of the reset tension spring 71 to achieve reset. At this time, the rotating shaft 3 is still in the original position and will not rotate with the lever 7. When the reset tension spring 71 drives the lever 7 to reset, the lever 7 is limited by the first limit block 171, and when the lever 7 is moved, the lever 7 is limited by the second limit block 172.

[0054] The basic working principle of the present invention is: the lever 7 is moved axially along the rotating shaft 3. When the lever 7 is moved, the lever 7 abuts against the arc block 32, so that the lever 7 drives the rotating shaft 3 to rotate through the arc block 32. The rotating shaft 3 rotates to make the driving rod 4 move relative to the rotating shaft 3 to achieve unlocking. The driving rod 4 is hinged to the end of the front hinge rod assembly 11 to drive the front hinge rod assembly 11 from a supporting state to a bending state, so that the driving rod 4 can be unlocked relative to the rotating shaft 3, so that the front plate 22 and the rear plate 23 are placed flat on the bed frame 1. In addition, the use of the lever 7 as a driving component has the effect of lower cost compared to the motor.
