[0002] A transfer bed is a medical bed used for transferring patients between beds, as well as for transferring patients from operating tables to wards and from ambulances. In order to increase the comfort of patients when transferring patients between beds, some backrests on the transfer beds will be raised. The patient lies on the transfer bed with his back leaning against the backrest to increase the comfort of the patient. Chinese patent application No. 202322036049.X discloses a transfer bed, and it can be seen that the content describes a transfer bed with a fixed structure.

[0003] When the existing transfer bed is in use, some patients lie on the transfer bed with their backs leaning against the backrest, and the backrest is flipped and lifted up by a hydraulic rod. If the hydraulic rod fails during use, the hydraulic rod cannot lift up the backrest, and the backrest is easy to drop, causing the back of the patient leaning on the backrest to drop with the backrest, affecting the patient's use experience and even aggravating the patient's condition. For this reason, we propose a transfer bed with a fixed structure. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a transfer bed with a fixed structure, including an upper bracket 101, a bed body 102 and a backrest 103. A mounting frame 105 is fixedly arranged at the bottom of the upper bracket 101. A hydraulic rod 104 is rotatably connected to the mounting frame 105 through a lower rotating shaft. When in use, the hydraulic rod 104 can lift the backrest 103. The top of the hydraulic rod 104 is rotatably connected to the backrest 103 through the upper rotating shaft. The bottom of the backrest 103 is rotatably connected to the bed body 102 through a rotating column. When in use, the backrest 103 can be rotated and flipped through the rotating column. Two sets of limiting fixing components are arranged between the upper bracket 101 and the backrest 103. The limiting fixing components include an arc plate 300 and a lower block 301. The interior of the arc plate 300 and along the circumferential direction of the arc plate 300 A plurality of through holes 305 are evenly provided, a screw hole is provided inside the lower block 301, a T-shaped stud 304 is arranged inside the screw hole, a working end of the T-shaped stud 304 passes through the inside of the through hole 305, a nut 303 is threadedly connected to the outside of the T-shaped stud 304, and the T-shaped stud 304 can be further locked and fixed by the nut 303 when in use, and the T-shaped stud 304 is threadedly connected to the screw hole, the lower block 301 is located at the bottom of the upper bracket 101, the arc plate 300 is located at the bottom of the bed body 102, two groups of lower fixing plates 306 are fixedly provided on the top of the lower block 301, the lower fixing plates 306 and the upper bracket 101 are fixedly connected by bolts, an upper fixing plate 302 is fixedly provided on the top of the arc plate 300, and the upper fixing plate 302 and the backrest 103 are fixedly connected by screws.

[0024] In summary, the backrest 103 is flipped and lifted to a certain angle by the hydraulic rod 104 and then stops moving, driving the arc plate 300 to flip and move, and then check whether the working end of the T-shaped stud 304 is aligned with the corresponding through hole 305. If not, start the hydraulic rod 104 again. At this time, the working end of the hydraulic rod 104 extends or retracts to align the working end of the T-shaped stud 304 with the corresponding through hole 305. At this time, the hydraulic rod 104 stops, and then the T-shaped stud 304 is rotated in the direction close to the arc plate 300, and then the working end of the T-shaped stud 304 passes through the corresponding through hole 305, and then the nut 303 is tightened on the working end of the T-shaped stud 304, so that the raised backrest 103 can be limited, and then the patient can be transported on the transfer bed. When the hydraulic rod 104 fails, the backrest 103 can be limited and supported by the action of the limiting fixing component. When the backrest 103 is folded, the opposite principle is followed.

[0025] Example 2

[0026] See also Figures 1 to 6 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that.

[0027] In this embodiment, preferably, an extension component is provided on one side of the upper bracket 101, and the extension component includes an extension plate 200 and two groups of screw rods 201. Two groups of through grooves are opened inside one side of the upper bracket 101, and the ends of the screw rods 201 pass through the inside of the through grooves. The outside of the screw rod 201 is connected with an internal threaded ring 202 through a thread. When in use, the internal threaded ring 202 is tightened on the screw rod 201 to fix the screw rod 201, and the extension plate 200 is fixed on the screw rod 201. Through the designed extension component, when the patient is taller, the length of the extension bed can be increased, which makes it convenient for taller patients to use the transfer bed, further improving the use effect of the transfer bed.

[0028] In this embodiment, preferably, a lower bracket 100 is fixedly provided at the bottom of the upper bracket 101 , and four sets of rolling wheels and a placement plate 106 are respectively provided on the lower bracket 100 .

[0029] In summary, when the patient is tall and the transfer bed is short, the end of the screw 201 on the extension plate 200 is passed through the groove inside one side of the upper bracket 101, and then the internal threaded ring 202 is tightened on the working end of the screw 201 to fix and lock it on the upper bracket 101. At this time, the extension plate 200 can increase the length of the transfer bed, making it easier for taller people to use the transfer bed. When the extension plate 200 is not needed, the operation can be carried out according to the opposite principle mentioned above.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
