[0031] Combine Figures 1 to 5 The electric nursing bed frame of the utility model is further described.

[0032] An electric nursing bed frame is characterized by comprising a frame 1, a backrest frame 2, a thigh support frame 3, and a calf support frame 4.

[0033] The frame 1 is composed of a headboard frame 11 and a footboard frame 12. The sides of the headboard frame 11 and footboard frame 12 facing each other form a seat 5. Slideways 9 extending in the front-to-back direction are located on both the left and right inner walls of the headboard frame 11, facing the footboard frame 12. A roller 10, or wheel, is connected to the rear end of the backrest frame 2 via a plate 21. The roller 10 fits into the slideways 9. A first push rod motor 8 is located between the backrest frame 2 and the headboard frame 11 to lift the head of the backrest frame 2. The motor base of the first push rod motor 8 is connected to a crossbar 111 of the headboard frame 11 via a U-shaped mount. The piston rod of the first push rod motor 8 is connected to the head of the backrest frame 2 via a U-shaped mount, thereby driving the head of the backrest frame 2 to rotate up and down. When the head of the backrest frame 2 is lifted, the rear end of the backrest frame 2 simultaneously slides toward the head of the bed, preventing compression on the patient's waist and buttocks.

[0034] The head portion of the thigh support frame 3 is rotatably connected to the side of the foot frame 12 corresponding to the head frame 11 via a connecting plate and a corresponding connecting pin. A second push rod motor 20 is provided between the foot frame 12 and the thigh support frame 3 to lift the tail portion of the thigh support frame 3. The motor base end of the second push rod motor 20 is connected to the crossbar 111 of the foot frame 12 via a U-shaped seat. The piston rod of the second push rod motor 20 is connected to the tail portion of the thigh support frame 3 via a U-shaped seat, thereby driving the tail portion of the thigh support frame 3 to be raised or lowered.

[0035] The head of the calf support frame 4 is rotatably connected to the tail position of the thigh support frame 3 through a connecting plate and a connecting pin. A telescopic rod 6 for supporting the calf support frame is provided between the foot frame 12 and the calf support portion. The telescopic rod 6 can support the calf support frame 4. At the same time, the height of the calf support frame 4 can be adjusted through the telescopic function to meet the needs of the patient.

[0036] The headboard frame 11 and the footboard frame 12 are fixed by bolt connection or welding. In this embodiment, the two are fixed by bolt connection. When the bed frame is stored or transported, the headboard frame 11 and the footboard frame 12 can be separated to reduce the overall length of the bed frame and facilitate movement.

[0037] The headboard frame 11 and footboard frame 12 each include two parallel support beams 113 and a crossbar 111 disposed between the two support beams 113. A mounting beam 112 is also disposed between the crossbars 111 and 111 and is parallel to the support beams 113. The seat 5 is formed by two adjacent crossbars 111 in the headboard frame 11 and footboard frame 12, i.e., by the crossbar 111 at the rear of the headboard frame 11 and the crossbar 111 at the head of the footboard frame 12, and is used to support the buttocks of a patient in a sitting position.

[0038] The two support beams 113 in the headboard frame 11 are provided with connecting holes near the tail end, and the two support beams 113 in the footboard frame 12 are also provided with connecting holes near the head end. The tail end of the support beam 113 in the headboard frame 11 is docked with the head end of the support beam 113 in the footboard frame 12, and then the fixing plate is installed, and bolts are screwed into the fixing plate and the connecting holes to achieve the fixation of the headboard frame 11 and the footboard frame 12.

[0039] A support rod 7 is further provided between the backrest frame 2 and the headboard frame 11 , and both ends of the support rod 7 are rotatably connected to the mounting beam 112 of the headboard frame 11 and the backrest frame 2 respectively through connecting pins, thereby improving the stability of the backrest frame 2 .

[0040] The telescopic rod 6 includes an outer tube 62 , a moving rod 61 , a spring piece 64 , a latch 65 and a positioning plate 63 .

[0041] The outer tube 62 is a rectangular tubular structure formed from a bent steel plate. The head of the outer tube 62 has a through-hole through which it is pivotally connected to the mounting beam 112 of the footrest frame 12. The left and right sidewalls of the outer tube 62 define an axially extending guide groove 621 and a plurality of latching slots 622 located above and connected to the guide grooves 621. These latching slots 622 are also arranged axially along the outer tube 62. Each latching slot 622 is inclined, with the upper end of each slot 622 tilted toward the head of the outer tube 62 and the lower end connected to the guide groove 621. A latching pin 65 is positioned perpendicular to the outer tube 62. Its ends engage the guide grooves 621 on the left and right sidewalls of the outer tube 62, allowing it to move along the direction of the guide grooves 621. The head of the movable rod 61 fits within the outer tube 62 and defines a mounting opening 612. The rear end of the movable rod 61 is pivotally connected to the calf support frame 4. The spring 64 is disposed in the mounting opening 612 and connected to the bayonet 65. In its natural state, it drives the bayonet 65 upward, allowing the end of the bayonet 65 to engage with the slot 622 when passing through it. The positioning plate 63 fits within the outer tube 62 and is located to the side of the movable rod 61. The positioning plate 63 has an escape opening 632 for the end of the bayonet 65 to pass through, and a stop slot 633. The stop slot 633 corresponds to the guide slot 621 and limits the upward movement of the bayonet 65. When the movable rod 61 moves toward the head of the outer tube 62, the bayonet 65 slides into the stop slot 633, thereby pushing the positioning plate 63 to move synchronously. When the movable rod 61 is pulled toward the rear of the outer tube 62, the bayonet 65 disengages the stop slot 633, and the end of the movable rod 61 pulls the positioning plate 63 to move synchronously.

[0042] When the moving rod 61 moves toward the end of the outer tube 62, the latch 65 is located on the outside of the limiting groove 633, so the latch 65 can be sequentially engaged in each of the slots 622 passed through to achieve positioning. Since each of the slots 622 is arranged at an angle, even after the latch pin 65 enters the slot 622 , the latch pin 65 can be pulled out of the slot 622 by the moving rod 61 and continue to move along the guide slot 621 .

[0043] The spring clip 64 is a metal spring clip 64, and has a through hole connected to the pin 65 on one end near the head. The tail of the spring clip 64 has a curved foot 641, and the foot 641 is engaged in the slot 613 on the inner wall of the mounting opening 612, so that the head of the spring clip 64 is tilted upward, providing an upward elastic force for the pin 65, so that the pin 65 can slide into the slot 622 when passing through the slot 622 without other restrictions.

[0044] An elastic support foot 631 is provided at the bottom of the positioning plate 63, and the elastic support foot 631 rests on the inner bottom wall of the outer tube 62, so that the top wall of the positioning plate 63 rests on the inner top wall of the outer tube 62, ensuring the stability and friction of the positioning plate 63 in the outer tube 62, and avoiding the problem of the positioning plate 63 sliding arbitrarily in the outer tube 62.

[0045] The head of the movable rod 61, i.e., the end located within the outer tube 62, is bent toward the positioning plate 63, forming a curved portion 611 that pulls the positioning plate 63 to move synchronously. When the latch 65 is located in the retaining groove 633, the distance between the positioning plate 63 and the curved portion 611 is greater than the depth of the retaining groove 633, allowing the latch 65 sufficient space to pull back and escape from the retaining groove 633.

[0046] It should be noted that, in this embodiment, for the convenience of description, the head portion of each component is the side facing the head of the bed, and the tail portion is the side facing the foot of the bed.
