Detailed Implementation
[0036] The following description is merely a preferred embodiment of this application and is not intended to limit the scope of this application.
[0037] like Figures 1-12 As shown, a physiotherapy bed with lifting function includes a base plate 21, a perforated mounting plate 22, a ball screw 23, a motor 24, a foam mattress 25, and an X-shaped hinged frame 26. It also includes a drive square block 1 disposed on the end face of the ball screw 23, an inner square ring 2 disposed on the motor 24 and used to fit the drive square block 1, a sliding frame unit 3 disposed on the base plate 21 and connected to the motor 24 and used to connect the drive square block 1 and the inner square ring 2, and an inner square manually rotating frame unit 4 disposed on the base plate 21 and used to fit the drive square block 1.
[0038] In this embodiment, the base plate 21 is rectangular in shape and can be provided with weight-reducing openings and rollers. The openings on the perforated mounting plate 22 are circular holes for fitting the smooth rod portion of the ball screw 23. The ball screw 23, motor 24, foam mattress 25, and X-shaped hinge frame 26 are all existing structures or commercially available products. After the ball screw 23 rotates, the vertical dimension of the X-shaped hinge frame 26 can be changed, thereby achieving the purpose of adjusting the height of the foam mattress 25, making it convenient for users to get on and off the bed. Specifically, the hinge-sleeve block 26-1 on the X-shaped hinge frame 26 is sleeved with the limiting rod 27, and the lower hinge block on the X-shaped hinge frame 26 is screwed to the slider on the ball screw 23.
[0039] The motor 24 and the inner square manual rotating frame unit 4 can be used interchangeably, and the number of the driving square blocks 1 is 1 or 2, so that the lifting function can be both electric and manual, thereby improving the practicality of the physiotherapy bed.
[0040] Furthermore, the cross-sectional shape of the drive square block 1 is square. The cross-sectional shape of the inner square ring 2 is either an inner and outer square or an inner square and an outer circle. It is always fitted onto the motor shaft of the motor 24. After the sliding frame unit 3 is opened for use, the drive square block 1 is fitted onto it, so that the motor 24 can rotate to drive the ball screw 23.
[0041] Correspondingly, the sliding frame unit 3 sliding closer to or further away from the motor 24 and ball screw 23, aligning and engaging the inner square ring 2 and the driving square block 1, and installing and removing the inner square manual rotating frame unit 4 from the driving square block 1 can all be performed by the medical staff in charge of the physiotherapy bed.
[0042] Finally, it should also be noted that: First, the physiotherapy function is mainly achieved through the foamed mattress 25; Secondly, the base plate 21 is also provided with a tool limiting frame 12. The inner square manual rotating frame unit 4 is stably placed in the tool limiting frame 12 before and after use, thereby preventing it from falling and being lost.
[0043] The sliding frame unit 3 includes an inverted L-shaped fixing plate 301 disposed on the upper surface of the base plate 21, and an L-shaped sliding plate 302 disposed on the upper surface of the base plate 21, engaging with the inverted L-shaped fixing plate 301, and used to support the motor 24.
[0044] In this embodiment, there are two of each of the inverted L-shaped fixing plate 301 and L-shaped sliding plate 302, which are engaged in pairs to ensure that the inner square ring 2 on the motor 24 and the driving square block 1 are only separated left and right, and their circumferential alignment is not necessarily correct, but they are consistent in vertical height and front-back position. The "left and right" direction corresponds to the length direction of the physiotherapy bed, and the "front-back" direction corresponds to the width direction of the physiotherapy bed.
[0045] Furthermore, the general usage method of the sliding frame unit 3 is as follows: First, slide the motor 24 relatively large to bring the inner square ring 2 close to the driving square block 1; Second, manually rotate the inner square ring 2 to align it with the driving square block 1; Third, and finally, the motor 24 is slid relatively slightly so that the inner square ring 2 simultaneously engages the square block on the motor shaft and the driving square block 1, and then the motor 24 is turned on.
[0046] The sliding frame unit 3 also includes fastening bolts 303 disposed on the inverted L-shaped fixing plate 301 and used to clamp the L-shaped sliding plate 302.
[0047] In this embodiment, the inverted L-shaped fixing plate 301 is provided with screw holes for installing the fastening bolt 303. After the fastening bolt 303 clamps the L-shaped sliding plate 302 inward, the inner square ring 2 can be prevented from spontaneously separating from the driving square block 1.
[0048] Correspondingly, the L-shaped sliding plate 302 is welded or screwed to the motor 24, and the fastening bolt 303 can also prevent the motor 24 from sliding out and falling when it is not in use.
[0049] The inner square manual rotating frame unit 4 includes a rotating plate 401 for driving the ball screw 23, an inner square tube 402 disposed at one end of the rotating plate 401 and used to sleeve the driving square block 1, and a gripping rod 403 and a gripping sleeve 404 disposed at the other end of the rotating plate 401 and used to drive the rotating plate 401.
[0050] In this embodiment, the main body of the inner square manual rotating frame unit 4 is made of high-strength steel, and the grip sleeve 404 is made of rubber. The inner square tube 402 and the inner square ring 2 have the same cross-sectional shape and size, but the former is longer than the latter.
[0051] There are two ball screws 23, and their threads rotate in opposite directions. A connecting rod 5 is provided between the two ball screws 23.
[0052] In this embodiment, the ball screw 23 is a commercially available ball screw with a self-locking function. That is, when the motor 24 and the inner square manual rotating frame unit 4 are not connected to it, the user's weight transmitted downward at the X-shaped hinge frame 26 will not drive the screw part of the ball screw 23 to rotate in the reverse direction.
[0053] The connecting rod 5 can be either a round rod or a square rod, and it is welded to the end faces of the two ball screws 23 to form an integral structure.
[0054] The ball screw 23 is also provided with an end limiting block 6 for engaging the perforated mounting plate 22.
[0055] In this embodiment, the end limiting block 6 is annular in shape, and it is welded and fixed to the smooth part of the ball screw 23, thereby enabling: The overall structure consisting of two end limit blocks 6, two ball screws 23, one connecting rod 5, and two drive square blocks 1 can only rotate on the two perforated mounting plates 22, and cannot move forward, backward, left, right, up, or down.
[0056] The physiotherapy bed also includes a sleeve body unit 7 disposed on the base plate 21, and a perforated bed frame unit 8 disposed on the sleeve body unit 7 and used to install the foam mattress 25.
[0057] In this embodiment, the I-shaped plate 11 can be further provided on the lower surface of the perforated bed frame unit 8, so that the installation position of the limiting rod 27 and the sleeve tube unit 7 is relatively centered on the perforated bed frame unit 8, ensuring a relatively stable support effect.
[0058] The sleeve body unit 7 consists of four units, corresponding to the four end positions of the I-shaped plate 11. Each end of the limiting rod 27 has a fixing block, which is connected to the central plate of the I-shaped plate 11. Both hinge-sleeve blocks 26-1 are sleeved with the limiting rod 27.
[0059] The sleeve body unit 7 includes a fixed outer tube 701 disposed on the upper surface of the base plate 21, a lifting inner tube 702 inserted into the fixed outer tube 701, an insertion hole 703 disposed on the fixed outer tube 701 and the lifting inner tube 702, and a support rod 704 disposed on the insertion hole 703.
[0060] In this embodiment, the X-shaped lifting frame 26 provides stepless lifting adjustment; the positioning hole 703 and the positioning pin 704 cooperate to provide stepped height positioning, which can serve as auxiliary support after the X-shaped lifting frame 26 is adjusted, because the user of this physiotherapy bed generally has a range of requirements for the height of the foam mattress 25.
[0061] The aforementioned stepped adjustment is set to, for example, three levels, meaning that the number of insertion holes 703 on the fixed outer tube 701 is three, which can generally meet the user's needs for adjusting the height of the physiotherapy bed.
[0062] Therefore, the fixed support function at the support rod 704 can serve as a supplement to the support function at the X-shaped hinge frame 26 after adjustment.
[0063] The fixed outer tube 701 and the lifting inner tube 702 are always connected, and the effective connection size is sufficient and appropriate to avoid significant lateral swaying of the perforated bed frame unit 8.
[0064] The sleeve tube unit 7 further includes two vertical grooves 705 disposed on the lifting inner tube 702 for inserting and storing the unused support rod 704, and a vertical protrusion 706 disposed on the inner side of the fixed outer tube 701 for inserting into one of the vertical grooves 705.
[0065] In this embodiment, the vertical groove 705 has at least the following three functions: First, the cross-sectional shape of the lifting inner tube 702 is upgraded from the original rectangular ring to a polygonal ring, increasing the difficulty of its bending deformation and improving its structural strength. Secondly, one of the two vertical grooves 705 is used to insert and store the support rod 704 that may not be used, so as to prevent the support rod 704 from being lost when not in use; Third, the other of the two vertical grooves 705 is used to engage the vertical protrusion 706, thereby increasing the insertion accuracy between the fixed outer tube 701 and the lifting inner tube 702, making the perforated bed frame unit 8 less prone to sliding.
[0066] It should be noted that: First, the length of the fixed outer tube 701 should not be significantly greater than the length of the support rod 704; otherwise, after the support rod 704 is placed in the vertical groove 705 for storage, it will be difficult to pull it out upwards. Secondly, the diameter of the support rod 704 is significantly smaller than the opening size of the vertical groove 705, so as to avoid the idle and stored support rod 704 causing significant wear to the lifting inner tube 702 during the lifting process.
[0067] A magnet 9 is provided on one of the support surfaces of the foam mattress 25; the perforated bed frame unit 8 includes a rectangular frame 801 disposed on the lifting inner tube 702, a recessed plate 802 disposed on the rectangular frame 801 and used to support the foam mattress 25, and a ventilation and heat dissipation hole 803 disposed on the recessed plate 802 and used to expose the magnet 9 downwards.
[0068] In this embodiment, the magnet 9 is hemispherical in shape, and the pad 10 is bonded to its plane. The pad 10 is then bonded to one of the support surfaces of the foam mattress 25, making it relatively difficult for the magnet 9 to sink into the foam mattress 25, thus providing the user with a relatively obvious passive massage magnetic therapy effect.
[0069] On the other hand, the height of the upper surface of the sunken plate 802 is lower than the height of the upper surface of the rectangular frame 801, which makes the foam mattress 25 fit into the perforated bed frame unit 8 and prevents it from slipping off.
[0070] The function of the ventilation and heat dissipation hole 803 includes at least the following: First, the mattress is breathable and dissipates heat. Secondly, when the magnet 9 is left unused, the sinking plate 802 is prevented from pressing on the magnet 9 for a long time, thereby protecting the magnet 9 and the foam mattress 25.
[0071] The foam mattress 25 can be made of polyurethane foam, latex foam, or memory foam. The pad 10 is circular or square in shape, and its area is 2-5 times the planar area of the magnet 9. The magnet 9 is a commercially available artificial permanent magnet product, such as neodymium iron boron magnet.
[0072] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this application. These are non-inventive modifications and are protected by patent law as long as they are within the scope of the claims of this application.
