[0005] The bed frame consists of an outer rectangular frame, a first fixing rod, a second fixing rod, and an H-shaped fixing bracket. The first and last ends of each first fixing rod are fixed to the two short sides of the outer rectangular frame, and each first fixing rod is fixed to the two long sides of the outer rectangular frame through the second fixing rod. The two first fixing rods are fixedly connected by the H-shaped fixing bracket.

[0006] The head lifting assembly includes: a first connecting rod, two sets of Y-shaped connecting rods, and a second connecting rod; the bottoms of the two sets of Y-shaped connecting rods are fixed to both ends of the first connecting rod. Each Y-shaped connecting rod consists of a long connecting rod and a short connecting rod. The bottom of the short connecting rod is rotatably connected to the middle of the long connecting rod, and the top of the short connecting rod is one top of the Y-shaped connecting rod, while the top of the long connecting rod is the other top of the Y-shaped connecting rod. The second connecting rod is fixed between the short connecting rods of the two sets of Y-shaped connecting rods. For each Y-shaped connecting rod, one top is connected to a first fixed rod, and the other top is slidably connected along the inner side of the first fixed rod.

[0013] Furthermore, for each Y-shaped link, one top is connected to the first fixed rod, and the other top is slidably connected along the inner side of the first fixed rod. The specific structure is as follows:

[0014] For each Y-shaped link, one top is connected to the first fixed rod, and the other top is connected to the head slider inside the first fixed rod via a pivot through a head groove on the first fixed rod.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0016] (1) This utility model adjusts the tilt angle of the head side by adjusting the position of the other top of the Y-shaped connecting rod in the head lifting assembly within the head slide groove, and adjusts the tilt angle of the leg side by adjusting the position of the other top of the Y-shaped connecting rod in the leg slide groove. It can also be adjusted simultaneously to achieve the height adjustment of the bed frame, enriching the adjustment function of the nursing bed and making it convenient for patients to use.

[0017] (2) This utility model sets a sliding groove on the first fixed rod, and sets the other top of the Y-shaped connecting rod in the sliding groove by a slider. The Y-shaped connecting rod drives the slider to slide in the sliding groove, thereby driving the bed frame to rise and fall. This lifting and sliding structure is simple, easy to manufacture and has low manufacturing cost, and is convenient for patients to use.

[0018] (3) This utility model adopts a hidden sliding structure, with the sliding groove directly inside the first fixed rod, reducing the welding of external sliding grooves, reducing welding errors, and has the advantages of dust prevention, longer lubrication oil life, reduced maintenance, and simple and beautiful appearance.

[0030] The bed frame 1 consists of an outer rectangular frame 11, first fixing rods 12, second fixing rods 13, and an H-shaped fixing bracket 14. Specifically, the two first fixing rods 12 are fixed inside the outer rectangular frame 11, that is, the first and last ends of the first fixing rods 12 are fixed to the two short sides of the outer rectangular frame 11 respectively, and the first fixing rods 12 are fixed to the two long sides of the outer rectangular frame 11 through the second fixing rods 13. The two first fixing rods 12 are fixedly connected by the H-shaped fixing bracket 14. In this embodiment, two sliding grooves 121 are provided on the inner side of the two first fixing rods 12, denoted as the head sliding groove and the leg sliding groove. Corresponding to the same first fixing rod 12, the head sliding groove and the leg sliding groove are symmetrically arranged on both sides of the H-shaped fixing bracket 14. Figure 5 , Figure 6 and Figure 7 As shown, the first fixing rod 12 is a hollow tube, and a head slider and a leg slider are built into the corresponding areas of the head slide groove and the leg slide groove. This embodiment adopts a hidden sliding structure, with the slide groove 121 directly inside the first fixing rod 12, reducing the need for external slide groove welding, reducing welding errors, and providing advantages such as dust prevention, longer lubrication oil life, reduced maintenance, and a simple and beautiful appearance.

[0031] The head lifting assembly 3 includes: a first connecting rod 31, two sets of Y-shaped connecting rods 32, and a second connecting rod 33. The bottoms of the two sets of Y-shaped connecting rods 32 are fixed to both ends of the first connecting rod 31. For each Y-shaped connecting rod 32, one top is connected to the first fixed rod 12, and the other top passes through a head sliding groove on the first fixed rod 12 via a pivot and is connected to the head slider inside. Specifically, each Y-shaped connecting rod 32 consists of a long connecting rod 321 and a short connecting rod 322. The bottom of the short connecting rod 322 is connected to the middle of the long connecting rod 321, the top of the short connecting rod 322 is one top of the Y-shaped connecting rod 32, and the top of the long connecting rod 321 is the other top of the Y-shaped connecting rod 32. The second connecting rod 33 is fixed between the short connecting rods of the two sets of Y-shaped connecting rods 32.

[0032] The structure of the leg lifting assembly is the same as that of the head lifting assembly, so it will not be described in detail.

[0033] The head cylinder assembly 5 includes a head cylinder and a matching fixing assembly. The head cylinder is fixed on the H-shaped fixing bracket 14, and its actuating end acts on the second connecting rod 33.

[0034] The structure of the leg cylinder assembly is the same as that of the head cylinder assembly, so it will not be described in detail.

[0035] Among them, such as Figure 3 and Figure 4As shown, each caster assembly 2 used in this embodiment includes: two casters 21 and a caster connecting assembly for connecting the two casters 21 to the head lifting assembly / leg lifting assembly. The caster connecting assembly includes: a caster bracket 22, a roller fixing shaft 23, a limiting plate 24, and a limiting screw 25. The roller fixing shaft 23 is located at the center of the caster bracket 22. The limiting plate 24 has an arc-shaped structure and is located on the caster bracket 22 and above and to the right of the roller fixing shaft 23. The limiting screw 25 is located on the outer side of one end of the limiting plate 24. When the limiting screw 25 contacts one end of the limiting plate 24, the roller fixing shaft 23 also contacts one end of the limiting plate 24, thereby limiting the two casters 21.

[0036] The nursing bed proposed in this embodiment can achieve overall height adjustment, head-high-feet-lower, and head-lower-feet-higher configurations through the head cylinder assembly and leg cylinder assembly. The caster assembly used in this embodiment also includes an anti-tipping limit function. Specifically, the head cylinder assembly drives the Y-shaped connecting rod, causing the other end of the Y-shaped connecting rod to slide backward along the head slide groove from its initial position, achieving a head-lower-feet-higher configuration. The leg cylinder assembly drives the Y-shaped connecting rod, causing the other end of the Y-shaped connecting rod to slide forward along the leg slide groove from its initial position, achieving a head-higher-feet-lower configuration. Simultaneous adjustment of the head cylinder assembly and leg cylinder assembly allows for overall height adjustment.
