Description

Technical Field

[0001] The utility model relates to the field of nursing beds, in particular to an electric nursing bed. Background Art

[0002] With the development of technology, nursing beds are becoming more and more widely used in people's lives. Since some patients who use nursing beds are critically ill or seriously disabled and most of them have lost their ability to move, most nursing beds in the existing technology integrate multiple functions to facilitate patients to turn over, get up, move, etc.

[0003] For example, patent document CN211356357U discloses a postpartum rehabilitation nursing bed for obstetrics and gynecology. This bed facilitates daily activities for mothers, such as getting up and getting in and out of bed, and also facilitates daily care for infants and young children, making it highly practical. However, this bed also has drawbacks during use: it lacks a temporary brake mechanism and can only be braked using self-locking universal wheels. Therefore, when the bed needs to be temporarily stopped during movement, it can only be positioned manually or using the self-locking function of the universal wheels, which is inconvenient to operate. Utility Model Content

[0030] Combine Figures 1 to 5 The electric nursing bed of the utility model is further described.

[0031] An electric nursing bed is characterized by comprising a bed frame 1, a bed plate frame 2, a lifting component 3, a rolling component 4 and a brake component 5.

[0032] The bed frame 1 includes a bed bottom frame, a headboard, a footboard, and a detachable baffle arranged between the headboard and the footboard.

[0033] The bed frame 2 is fixed to the bed base of the bed frame 1. In this embodiment, the bed frame 2 has a back lift 21 for facilitating the patient's standing and a leg lift 22 for facilitating the patient's legs. The back and leg lifts of the bed frame 2 are both existing technologies and commercially available, so they are not described in detail in this embodiment.

[0034] The lifting assembly 3 has two groups, which are distributed along the front and rear directions of the bed frame 1 and are fixedly arranged at the bottom of the bed frame 1 in a symmetrical state to drive the bed frame 1 to move up and down. The rolling assembly 4 is arranged at the bottom position of the lifting assembly 3.

[0035] The brake assembly 5 is arranged on the rolling assembly 4, and comprises a brake mechanism 51 and a driving mechanism 52. The brake mechanism 51 comprises a limiting tube 511, a brake column 512 and a brake tube 516. The limiting tube 511 is fixed in a vertical state on the rolling assembly 4. A bottom cover 513 is welded or screwed on the lower opening of the limiting tube 511, and the bottom cover 513 has a through hole in which a guide sleeve 514 is fixed. The brake column 512 is arranged in the guide sleeve 514 in a lifting manner, and a brake pad 5122 is arranged at the lower end of the brake column 512. An elastic member, which is a spring 515, is arranged between the brake column 512 and the limiting tube 511 to upwardly push the brake column 512. The spring 515 is sleeved on the guide sleeve 514, the lower end of the spring 515 is supported on the inner wall of the bottom cover 513, and the upper end of the spring 515 is supported on a shoulder 5121 at the top of the brake column 512, so that the brake column 512 is upwardly pushed in a natural state and does not contact the ground. The brake tube 516 is arranged in the limiting tube 511 and above the brake column 512. The side wall of the brake tube 516 has two connecting plates 517, and a pressure roller 518 is connected between the two connecting plates 517. The pressure roller 518 is in contact with the top wall of the brake column 512. The driving mechanism 52 is connected with the brake tube 516 to drive the brake tube 516 to rotate, and at the same time drive the pressure roller 518 to rotate downward to press the brake column 512 to move downward, so that the lower end of the brake column 512 contacts the ground to temporarily brake.

[0036] The lifting assembly 3 comprises a short cross arm 31, a long cross arm 32 and a push rod motor 33. The short cross arm 31 and the long cross arm 32 each comprise two parallel side rods and a plurality of transverse rods connected between the two side rods. The length of the side rods in the long cross arm 32 is 2-3 times the length of the side rods in the short cross arm 31. The upper ends of the two side rods in the short cross arm 31 are rotatably connected to the bed bottom frame at the bottom of the bed frame 1 through a U-shaped seat, and the lower ends are rotatably connected to the long cross arm 32 at a position close to the middle. The upper ends of the two side rods in the long cross arm 32 are connected with rolling members, i.e. rollers, which are matched in the sliding groove 34 of the bed bottom frame, and the lower ends are provided for mounting the rolling assembly 4. The sliding groove 34 extends along the front-rear direction of the bed frame 1, so that the upper end of the long cross arm 32 can move in the front-rear direction of the bed frame 1. The upper end of the push rod motor 33, i.e. the end of the motor seat, is rotatably connected to the bottom of the bed frame 1 through a U-shaped seat, and the lower end of the push rod motor 33, i.e. the end of the piston rod, is rotatably connected to the transverse rod of the short cross arm 31 to drive the short cross arm 31 and the long cross arm 32 to open or close, thereby achieving the function of lifting the bed frame 1.

[0037] The rolling assembly 4 comprises a connecting rod 41 mounted on the lower ends of the two side rods in the long cross arm 32, mounting plates 42 arranged on both ends of the connecting rod 41, and rolling wheels 43 arranged on the mounting plates 42. Each mounting plate 42 has two rolling wheels 43 in front and back, which can improve the stability of the support of the nursing bed.

[0038] The brake mechanism 51 comprises two groups, each mounted on two mounting plates 42 of the same rolling assembly 4, located outside the rolling wheel 43 for easy operation by the operator. The drive mechanism 52 comprises a brake transmission rod 522, a brake pedal rod 523, and a connecting plate 521. The two ends of the brake transmission rod 522 are connected to the connection holes of the limiting tubes 511 of the two brake mechanisms 51, respectively. The brake transmission rod 522 is capable of circumferential rotation relative to the limiting tubes 511. Simultaneously, the brake transmission rod 522 is circumferentially limited in position with the brake tube 516, allowing the brake transmission rod 522 to drive the brake tube 516 to rotate synchronously. The brake pedal rod 523 is located outside the brake transmission rod 522 and is connected to the brake transmission rod 522 via the connecting plate 521. By stepping on the brake pedal rod 523, the brake transmission rod 522 rotates, which in turn drives the brake tube 516 to rotate, pressing the brake column 512 downward, achieving the braking function.

[0039] The matching structure between the brake tube 516 and the brake transmission rod 522 is that the side wall of the end of the brake transmission rod 522 that passes through the connecting hole of the limiting tube 511 is a hexagonal structure 5221, and the center hole of the limiting tube 511 is also a hexagonal structure, thereby forming a circumferential limiting matching structure.

[0040] An upper limit rod 53 and a lower limit rod 54 are provided on the outer wall of the limit tube 511, and the connecting plate 521 is located between the upper limit rod and the lower limit rod to limit the rotation range and prevent the brake pedal rod 523 from being excessively stepped down or lifted up.
