Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0017] Furthermore, the terms "first," "second," etc., used in this document do not specifically refer to order or sequence, nor are they intended to limit this application; they are merely used to distinguish components or operations described using the same technical terms.

[0018] Please see Figure 1 This is a perspective view of the tilting support state of the lifting and tilting frame of this application; as shown in the figure, the lifting and tilting frame 1 of this embodiment is mainly used on a nursing bed to adjust the tilt of the nursing bed. The lifting and tilting frame 1 includes a support frame 2, a lifting frame 3, and a drive assembly 4. The support frame 2 has a first side 201, a second side 202, and a middle section 203 located between the first side 201 and the second side 202, as shown in the figure. Figure 1 As shown, the first side 201 is located on the left side of the load-bearing frame 2, and the second side 202 is located on the right side of the load-bearing frame 2. A first groove 21 is provided on the middle section 203 of the load-bearing frame 2 near the first side 201. The first groove 21 extends along the length of the load-bearing frame 2. The load-bearing frame 2 is a rectangular frame, and the first groove 21 is a rectangular channel steel.

[0019] One side of the lifting frame 3 is pivotally connected to the second side 202 of the supporting frame 2, as shown below. Figure 1 As shown, the right side of the lifting frame 3 is pivotally connected to the right side of the supporting frame 2. A second slide groove 31 is provided on the other side of the lifting frame 3. The second slide groove 31 extends along the length of the lifting frame 3. The lifting frame 3 is a rectangular frame, and the first slide groove 21 is a rectangular channel steel. The drive assembly 4 includes a linkage 41 and a drive component 42. The lower end of the linkage 41 is movably disposed within the first slide groove 21. The upper end of the linkage 41 is movably disposed within the second slide groove 31. The linkage 41 achieves lifting and rotation by sliding its upper and lower ends within the corresponding second slide groove 31 and first slide groove 21. The drive end of the drive component 42 is connected to the linkage 41. The drive component 42 is configured to drive the upper and lower ends of the linkage 41 to slide within the corresponding first slide groove 21 and second slide groove 31, thereby causing the lifting frame 3 to rotate around its pivot end.

[0020] In this embodiment, the lifting and tilting frame 1 is pivotally connected to the right side of the lifting frame 3 and the second side 202 of the supporting frame 2. A first sliding groove 21 is provided on the middle section 203 of the supporting frame 2 near the first side 201, and a second sliding groove 31 is provided on the other side of the lifting frame 3. The upper and lower ends of the linkage member 41 are movably disposed in the corresponding first sliding groove 21 and second sliding groove 31. The upper and lower ends of the linkage member 41 are driven to slide in the corresponding first sliding groove 21 and second sliding groove 31 by the driving member 42, thereby causing the lifting frame 3 to rotate around its pivot end, thus adjusting the tilt angle of the lifting frame 3. The lifting and tilting frame 1 of this embodiment has a simple structure, and the height adjustment process is completed by electric operation, which is convenient to operate.

[0021] See alsoFigure 1 As shown, in the embodiment, the linkage 41 comprises a linkage frame 411 and pulleys 412 arranged at the upper and lower ends of the linkage frame 411. The upper and lower ends of the linkage frame 411 are arranged in the first sliding groove 21 and the second sliding groove 31 through the sliding groove. The driving end of the driving member 42 is connected to the lower end of the linkage frame 411. When the linkage 41 drives the lifting frame 3 to rotate upward around the pivot end, the pulley 412 in the first sliding groove 21 slides to the side away from the pivot end of the lifting frame 3, and the pulley 412 in the second sliding groove 31 slides to the side close to the pivot end of the lifting frame 3. The linkage 41 further comprises two second linkage rods 413. The two second linkage rods 413 are symmetrically arranged on both sides of the width direction of the lifting frame 3. One end of the two second linkage rods 413 is pivotally connected to the middle segment 203 of the linkage frame 411. The other end of the two second linkage rods 413 is pivotally connected to the middle segment 203 of the lifting frame 3.

[0022] Referring back to Figure 1 As shown, in the embodiment, the driving member 42 comprises a cylinder body 421 and a telescopic rod 422. The cylinder body 421 is pivotally connected between the first sliding groove 21 and the second side 202 of the bearing frame 2. The telescopic rod 422 is arranged in the driving cylinder body 421. One end of the telescopic rod 422 away from the driving cylinder body 421 is pivotally connected to the linkage frame 411. The driving member 42 drives the upper and lower ends of the linkage 41 to slide in the corresponding first sliding groove 21 and the second sliding groove 31 by driving the telescopic rod 422 to extend or retract in the cylinder body 421. The driving member 42 further comprises a driving motor 423. The driving motor 423 is arranged in the driving cylinder body 421. The driving cylinder body 421 is used to drive the telescopic rod 422 to extend or retract in the cylinder body 421. When the driving cylinder body 421 drives the telescopic rod 422 to extend in the cylinder body 421, the telescopic rod 422 pushes the linkage 41 to drive the lifting frame 3 to rotate upward around the pivot end. When the driving cylinder body 421 drives the telescopic rod 422 to retract in the cylinder body 421, the telescopic rod 422 pulls the linkage 41 to drive the lifting frame 3 to rotate downward around the pivot end.

[0023] Referring back to Figure 2 With Figure 3 , Figure 2 is a perspective view of the lifting and tilting frame of the present application supporting a nursing bed board and Figure 3 is Figure 2 a side view; as shown, in the embodiment, the lifting and tilting frame 1 further comprises a plurality of leg support columns 5. The plurality of leg support columns 5 are arranged at the bottom of the bearing frame 2. The leg support columns 5 can be arranged in the bearing frame 2 through threaded connection. As Figure 2As shown, the number of leg support columns 5 is six, four of which are arranged at the bottom corners of the bearing frame 2, and the other two are arranged at the middle of the bearing frame 2. The lifting and tilting frame 1 further comprises a nursing bed board 6. The nursing bed board 6 is arranged on the bearing frame 2. The nursing bed board 6 is driven to adjust the tilting angle by rotating the lifting frame 3 around the pivotal end.

[0024] In summary, the present application provides a lifting and tilting frame, which pivots one side of the lifting frame to the second side of the bearing frame, and arranges a first sliding groove on the middle segment of the bearing frame close to the first side, and a second sliding groove on the other side of the lifting frame, and then movably arranges the upper and lower ends of the linkage in the corresponding first and second sliding grooves, and drives the upper and lower ends of the linkage to slide in the corresponding first and second sliding grooves by the driving member, so as to drive the lifting frame to rotate around the pivotal end, thereby adjusting the tilting angle of the lifting frame. The lifting and tilting frame of the present application has simple structure, and the height adjustment process is completed by electric operation, which is convenient to operate.
