Description

Technical Field

[0001] This application relates to the field of nursing beds, and more particularly to a lifting mechanism and a nursing bed. Background Technology

[0002] A nursing bed is a medical device designed for patients with limited mobility or those requiring prolonged bed rest. It offers multiple functions to meet the rehabilitation and care needs of patients. One key feature is its height adjustment mechanism, which enhances the user experience.

[0003] In related technologies, the lifting mechanism includes a bottom frame, a top frame, and a lifting assembly. The top frame is located above the bottom frame. The lifting assembly includes a first support frame, a second support frame, and a driving component. One end of the first support frame is rotatably connected to the top frame, and the other end is slidably and rotatably connected to the bottom frame. One end of the second support frame, which is close to the first support frame, is rotatably connected to the bottom frame, and the other end is slidably and rotatably connected to the top frame. The first support frame and the second support frame are rotatably connected at the middle position. The driving component is vertically arranged and installed between the bottom frame and the top frame to drive the top frame to move closer to or away from the bottom frame, thereby realizing the lifting of the nursing bed.

[0004] However, in practical applications, the space between the first support frame and the top frame is occupied, meaning that the lifting assembly occupies a large amount of space, which affects the installation of other parts of the nursing bed, so improvements are needed. Utility Model Content

[0005] In order to reduce the space occupied by the lifting components, in a first aspect, this application provides a lifting mechanism.

[0006] The lifting mechanism provided in this application adopts the following technical solution:

[0007] A lifting mechanism includes a base frame, a top frame, and a lifting assembly; the lifting assembly includes a first support frame, a second support frame, and a driving component; one end of the first support frame is rotatably connected to the base frame on both sides, and the other end of the first support frame is rotatably connected to the second support frame on both sides; one end of the second support frame is rotatably connected to the top frame on both sides, and the other end of the second support frame is slidably and rotatably connected to the base frame on both sides; one end of the driving component is rotatably connected to the top frame, and the other end is rotatably connected to the first support frame.

[0008] By adopting the above technical solution, in practical applications, the driving component works to drive the first support frame to rotate, thereby driving the rotation of one end of the second support frame and the sliding and rotation of the other end, so that the top frame moves closer to or away from the bottom frame, thereby realizing the lifting and lowering of the nursing bed; wherein, the space between the end of the first support frame away from the bottom frame and the top frame is not occupied, and other components of the nursing bed can be installed, and the driving component is installed between the top frame and the first support frame, making the overall structure of the lifting mechanism compact, thereby reducing the space occupied by the lifting components.

[0009] Preferably, the lifting assembly further includes two sliding rails and two pulleys. The two sliding rails are respectively disposed on both sides of the bottom frame, and the two pulleys are respectively rotatably connected to both sides of the second support frame, and the two pulleys are respectively confined within the two sliding rails.

[0010] By adopting the above technical solution, and by setting two sliding tracks and two pulleys, the sliding and rotating connection between the second support frame and the bottom frame can be realized.

[0011] Preferably, the sliding track is detachably connected to the bottom frame.

[0012] By adopting the above technical solution, a sliding rail is detachably connected to the bottom frame, so as to facilitate the installation and disassembly of the second support frame and the bottom frame.

[0013] Preferably, the lifting mechanism further includes two support components, which are respectively disposed on both sides of the second support frame near one end of the bottom frame. Each support component includes a support member, one end of which is rotatably connected to the second support frame, and the other end is slidably and rotatably connected to the top frame.

[0014] By adopting the above technical solution and setting two support components, the support component provides support between the second support frame and the top frame, thereby improving the stability of the lifting mechanism support and ensuring the stability of the nursing bed during lifting and use.

[0015] Preferably, the support assembly further includes a mounting shaft and a first limiting bolt, one end of the mounting shaft is movably inserted through the support member and threadedly connected to the second support frame, and the first limiting bolt is threadedly connected to the other end of the mounting shaft.

[0016] By adopting the above technical solution, and by setting an installation shaft and a first limit bolt, the installation and disassembly of one end of the support can be facilitated.

[0017] Preferably, the support assembly further includes a mounting wheel and a second limiting bolt. One end of the mounting wheel is slidably connected to the top frame, and the other end is movably inserted through the support member and threadedly connected to the second limiting bolt.

[0018] By adopting the above technical solution, and by setting up mounting wheels and a second limiting bolt, the installation and disassembly of the other end of the support can be facilitated.

[0019] Preferably, the support includes a first support column, a second support column, and a spring. One end of the first support column is rotatably connected to the second support frame. The second support column is movably limited to the first support column and its end, which is located away from the first support column, slides and is rotatably connected to the top frame. The spring is disposed between the first support column and the second support column to drive the second support column away from the first support column.

[0020] By adopting the above technical solution, by setting a first support column, a second support column and a spring, pressing the second support column compresses the spring to adjust the distance between the first support column and the second support column, so as to facilitate the installation between the first support column and the second support frame and between the second support column and the top frame.

[0021] Preferably, the support further includes a limiting plate and an adjusting rod. The limiting plate is disposed in the first support column, and the two ends of the spring abut against the limiting plate and the second support column, respectively. The adjusting rod is threaded to the end of the first support column away from the second support column and is rotatably connected to the limiting plate.

[0022] By adopting the above technical solution, by setting a limiting plate and an adjusting rod, and rotating the adjusting rod to adjust the position of the limiting plate, the spring is limited, thereby ensuring the stability of the second support column supporting the top frame.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a lifting mechanism.

[0038] Example 1:

[0039] Reference Figure 1 The lifting mechanism includes a bottom frame 1, a top frame 2, and a lifting assembly 3. Both the bottom frame 1 and the top frame 2 are rectangular and horizontally arranged, with the top frame 2 located above the bottom frame 1.

[0040] The lifting assembly 3 includes a first support frame 31, a second support frame 32, and a driving component 33. One end of the first support frame 31 is rotatably connected to the inner side of the bottom frame 1, and the other end of the first support frame 31 is rotatably connected to the middle portion of the second support frame 32. Simultaneously, one end of the second support frame 32 is rotatably connected to the inner side of the top frame 2, and the other end of the second support frame 32 slides and rotatably connects to the inner side of the bottom frame 1, with the sliding direction being the length direction of the bottom frame 1.

[0041] In this embodiment, the driving component 33 is an electric push cylinder. In other embodiments, the driving component 33 may also be a pneumatic cylinder, hydraulic cylinder, etc., and this application does not impose any restrictions. The cylinder body of the driving component 33 is rotatably connected to the top frame 2, and the power output shaft of the driving component 33 is rotatably connected to the first support frame 31.

[0042] In practical applications, the drive unit 33 is controlled to work, causing the power output shaft of the drive unit 33 to extend and retract within the cylinder, thereby driving the first support frame 31 to rotate, which in turn drives the rotation of one end of the second support frame 32 and the sliding and rotation of the other end, so that the top frame 2 moves closer to or further away from the bottom frame 1, thereby realizing the lifting and lowering of the nursing bed. With the support of the first support frame 31, the second support frame 32 and the drive unit 33, the stability of the lifting mechanism can be guaranteed.

[0043] The end of the first support frame 31 away from the bottom frame 1 and the top frame 2 are not occupied, allowing other components of the nursing bed to be installed here. The drive unit 33 is installed between the top frame 2 and the first support frame 31, making the overall structure of the lifting mechanism compact and reducing the space occupied by the lifting component 3.

[0044] Reference Figure 1 and Figure 2 In some embodiments, the lifting assembly 3 further includes two sliding rails 34 and two pulleys 35. The two sliding rails 34 are fixedly connected to both sides of the bottom frame 1 and are arranged along the length of the bottom frame 1. The two pulleys 35 are rotatably connected to both sides of the second support frame 32 and the sliding limit of the two pulleys 35 is located in the two sliding rails 34. The connection between the second support frame 32 and the bottom frame 1 is realized by using the sliding rails 34 and the pulleys 35, thereby facilitating the sliding and rotation between the second support frame 32 and the bottom frame 1.

[0045] In some embodiments, the sliding rail 34 is detachably connected to the base frame 1. In this embodiment, the sliding rail 34 is fixedly connected to the base frame 1 by bolts. In other embodiments, the sliding rail 34 can also be detachably connected to the base frame 1 by means of plugging, snapping, etc. When installing the second support frame 32, the second support frame 32 is first installed with the pulley 35 that is limited to the sliding rail 34, and then the sliding rail 34 is installed on the inside of the base frame 1 to facilitate the installation and removal of the second support frame 32 from the base frame 1.

[0046] The implementation principle of this embodiment is as follows: In practical application, the drive component 33 is controlled to work, so that the power output shaft of the drive component 33 extends and retracts in the cylinder, thereby driving the first support frame 31 to rotate, thereby driving the rotation of one end of the second support frame 32 and the sliding and rotation of the other end, so that the top frame 2 moves closer to or further away from the bottom frame 1, thereby realizing the lifting and lowering of the nursing bed. With the support of the first support frame 31, the second support frame 32 and the drive component 33, the stability of the lifting mechanism can be guaranteed.

[0047] The end of the first support frame 31 away from the bottom frame 1 and the top frame 2 are not occupied, allowing other components of the nursing bed to be installed here. The drive unit 33 is installed between the top frame 2 and the first support frame 31, making the overall structure of the lifting mechanism compact and reducing the space occupied by the lifting component 3.

[0048] Example 2:

[0049] Reference Figure 3 This embodiment is identical to Embodiment 1 in all other structural aspects, except that the lifting mechanism further includes two support components 4, which are respectively located on both sides of the second support frame 32 near the bottom frame 1. Specifically, each support component 4 includes a support member 41, one end of which is rotatably connected to the second support frame 32, and the other end is slidably and rotatably connected to the top frame 2, with the sliding direction being the length direction of the top frame 2. The support member 41 provides support between the second support frame 32 and the top frame 2, thereby improving the stability of the lifting mechanism and ensuring the stability of the nursing bed during lifting and use.

[0050] Reference Figure 3 and Figure 4 In some embodiments, the support assembly 4 further includes a mounting shaft 42 and a first limiting bolt 43. One end of the mounting shaft 42 is movably inserted through the support member 41 and threadedly connected to the second support frame 32 to realize the rotational connection between the support member 41 and the second support frame 32. The first limiting bolt 43 is threadedly connected to the other end of the mounting shaft 42 to restrict the support member 41 from disengaging from the mounting shaft 42. This facilitates the installation and disassembly of one end of the support member 41 and ensures the stability of the installation of the support member 41.

[0051] In some embodiments, the support assembly 4 further includes a mounting wheel 44 and a second limiting bolt 45. One end of the mounting wheel 44 is slidably connected to the top frame 2 in the direction of the length of the top frame 2, and the other end is movably inserted through the support member 41 to realize the rotational connection between the mounting wheel 44 and the support member 41, thereby realizing the sliding and rotation between the support member 41 and the top frame 2. The end of the mounting wheel 44 inserted through the support member 41 is threadedly connected to the second limiting bolt 45 to restrict the support member 41 from disengaging from the mounting wheel 44. This facilitates the installation and disassembly of the other end of the support member 41 and ensures the stability of the support member 41 during installation.

[0052] Reference Figure 4 and Figure 5In some embodiments, the support member 41 includes a first support column 411, a second support column 412, and a spring 413. One end of the first support column 411 engages with the mounting shaft 42. The second support column 412 is movably limited to the other end of the first support column 411, and the end of the second support column 412 away from the first support column 411 engages with the mounting wheel 44. The spring 413 is disposed between the first support column 411 and the second support column 412 to drive the second support column 412 away from the first support column 411. By pressing the second support column 412, the spring 413 is compressed to adjust the distance between the first support column 411 and the second support column 412. Thus, the support member 41 can be installed without adjusting the distance between the top frame 2 and the bottom frame 1, thereby facilitating the installation of the first support column 411 and the second support frame 32, as well as the second support column 412 and the top frame 2, and consequently facilitating the installation of the support assembly 4.

[0053] In some embodiments, the support assembly 4 further includes a limiting plate 414 and an adjusting rod 415. The limiting plate 414 is slidably limited within the first support column 411, and one end of the adjusting rod 415 is threadedly connected to the end of the first support column 411 away from the second support column 412 and rotatably connected to the limiting plate 414. Thus, by rotating the adjusting rod 415, the position of the limiting plate 414 can be adjusted, thereby limiting the spring 413 to ensure the stability of the second support column 412 supporting the top frame 2.

[0054] This application also discloses a nursing bed.

[0055] The nursing bed includes the lifting mechanism described in the above embodiments.

[0056] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
