Description

Technical Field

[0001] The utility model relates to the technical field of medical beds, in particular to a bed lifting device. Background Art

[0002] A hospital bed is a special bed used to provide a resting and treatment place for patients in a medical institution or a home care environment. In many cases, it is necessary to adjust the height and the pitch of the patient to cooperate with other equipment or medical staff for treatment, so a liftable hospital bed is often needed.

[0003] For example, the Chinese utility model patent with the publication number of "CN217430362U" discloses "an electric medical bed lifting device, including a bed frame and a base arranged under the bed frame. Two groups of parallel four-bar link mechanisms are symmetrically arranged on both sides of the base. The upper end of each group of parallel four-bar link mechanisms is hinged to the bed frame through a connecting rod, and the lower end of the parallel four-bar link mechanism is welded to the base. The same-side parallel four-bar link mechanisms are connected through a first shaft and a second shaft respectively, and a first electric push rod and a second electric push rod are respectively arranged between the first shaft and the second shaft. A channel steel is welded in the middle of the longitudinal beam of the base, and the pulley on the bed frame is restricted to roll in the channel steel. The utility model realizes the three functions of overall lifting, left inclination and right inclination by the linkage between two electric push rods, simplifies the drive source and reduces the production cost".

[0004] In view of the above related technologies, although two electric push rods can be used to drive the bed frame to lift, the production cost is reduced. However, when a patient uses a hospital bed, it is often not necessary to tilt the bed frame as a whole to the left or right. Usually, the left or right part of the bed board is tilted and rotated so that the patient can lean on the bed board or place the legs on the bed board, so that the patient can lie more comfortably on the bed board. Therefore, the practicability of the hospital bed in the above patent is relatively low. Therefore, the technical personnel in the field provide a bed lifting device to solve the problems put forward in the above background art. Summary of the Utility Model

[0005] In order to solve the problem that when a patient uses a hospital bed, it is often not necessary to tilt the bed frame as a whole to the left or right.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] An embodiment of the present utility model discloses a hospital bed lifting device. Refer to Figures 1-3 , a hospital bed lifting device, including a bed frame 1 and a bed board 2. The bed board 2 is located at the upper end of the bed frame 1. The bed board 2 is composed of a main bed board 201 and two side bed boards 202. One side of the two side bed boards 202 close to each other is hinged to the main bed board 201. Both the left and right ends of the inner side of the bed frame 1 are hinged with a support frame 3, and the top end of the support frame 3 is hinged to the bottom end of the side bed board 202. Both the left and right ends of the inner side of the bed frame 1 are fixedly connected with a support plate 4. The upper end of the support plate 4 is hinged with an electric push rod 5, and the top end of the electric push rod 5 is hinged to the bottom end of the side bed board 202. The middle of the bottom end of the main bed board 201 is fixedly connected with a plurality of electromagnets 6 and a mounting block 7. A limiting mechanism 8 cooperating with the electromagnet 6 is arranged on the mounting block 7;

[0019] By adopting the above technical solution, when it is necessary to adjust the use height of the bed board 2, the electric push rod 5 works and the support frame 3 cooperate to drive the bed board 2 to rise or fall, so as to facilitate the adjustment of the use height of the bed board 2.

[0020] Refer to Figure 3, the limiting mechanism 8 includes a connecting rod 801, an adsorption block 802, a connecting plate 803, two insertion rods 804 and a spring 805. The connecting rod 801 is inserted through the mounting block 7. The adsorption block 802 is fixedly connected to one end of the connecting rod 801. The connecting plate 803 is fixedly connected to the end of the connecting rod 801 away from the adsorption block 802. The two insertion rods 804 are both fixedly connected to the end of the connecting plate 803 away from the connecting rod 801. The spring 805 is sleeved on the outside of the connecting rod 801, and the two ends of the spring 805 are respectively connected to the mounting block 7 and the adsorption block 802. A cross plate 9 is fixedly connected to the bottom end of the side bed board 202. A plurality of jacks 10 for cooperating with the insertion rods 804 are opened on one side of the cross plate 9, and the end of the insertion rod 804 away from the connecting plate 803 is inserted into the jack 10. The adsorption block 802 is made of iron-nickel alloy material.

[0021] By adopting the above technical solution, when it is necessary to adjust the use angle of the side bed board 202, the adsorption block 802 can be adsorbed by the electromagnet 6 working. The adsorption block 802 is attached to the electromagnet 6 under the adsorption force of the electromagnet 6. At this time, the adsorption block 802 moves to drive the connecting rod 801 to move. The connecting rod 801 moves to drive the insertion rod 804 on the connecting plate 803 to move, so that the insertion rod 804 moves out of the jack 10 on the cross plate 9, thereby canceling the limit on the right side bed board 202. At this time, the use angle of the side bed board 202 can be adjusted by the electric push rod 5, so that the patient can be more comfortable when using the hospital bed.

[0022] Refer to Figure 1 and Figure 2 , a plurality of moving rollers 11 are fixedly connected to the bottom of the bed frame 1, and the four moving rollers 11 are distributed in a rectangle.

[0023] By adopting the above technical solution, it is convenient to move and transfer the hospital bed through the moving rollers 11.

[0024] Working principle: When this utility model is in use, the electrical components appearing in this application are externally connected to a power supply and a control switch during use. When it is necessary to adjust the use height of the bed board 2, the cooperation of the electric push rod 5 and the support frame 3 can drive the bed board 2 to rise or fall, thus facilitating the adjustment of the use height of the bed board 2. When it is necessary to adjust the use angle of the right side bed board 202, only need to make the electromagnet 6 on the right side work to adsorb the adsorption block 802. The adsorption block 802 fits with the electromagnet 6 under the adsorption force of the electromagnet 6. At this time, the adsorption block 802 moves to drive the connecting rod 801 to move, and the connecting rod 801 moves to drive the plug rod 804 on the connecting plate 803 to move, so that the plug rod 804 moves out of the jack 10 on the cross plate 9, thereby canceling the limit on the right side bed board 202. At this time, the electric push rod 5 on the right side can adjust the use angle of the side bed board 202, so that the patient can be more comfortable when leaning on the side bed board 202. When the patient wants to lift the legs, similarly, make the left side bed board 202 rotate, then the patient can place the legs on the left side bed board 202, thereby making the patient more comfortable when using the hospital bed, and further improving the practicality of the hospital bed.

[0025] When this utility model is in use, not only can the use height of the bed board 2 be adjusted, but also by adjusting the use angle of the side bed board 202, the patient can be more comfortable when using the hospital bed, thus further improving the practicality of the hospital bed.
