[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-3This utility model provides an embodiment of a self-tightening transfer frame, comprising two base frames 1. The base frames 1 serve as the fundamental support components of the entire transfer frame, and their stable structure ensures the installation of subsequent components and the realization of overall function. A support frame 3 is fixedly connected between the tops of the two base frames 1, connecting the tops of the two base frames 1 and enhancing the stability of the upper structure of the entire transfer frame. Two connecting plates 4 are rotatably connected to the top of the support frame 3. The connecting plates 4 can rotate flexibly according to actual needs, playing a role in adjusting the angle of the transfer frame to adapt to different terrains or user postures. The connecting plates 4 can rotate about their connection point with the support frame 3, providing a movable base for subsequent connected components. The angle can be adjusted according to actual working needs. Handrails 5 are fixedly connected to the ends of the two connecting plates 4 away from the support frame 3. The handrails 5 are used by the user to grip, providing a point of leverage when operating the transfer frame. A mounting frame 6 is fixedly connected to the bottom of the handrails 5, playing a key role in connecting the handrails 5 to other components, connecting the handrails 5 to the components below used for protection and tightening. A chest-shaped support is rotatably connected to the top of the mounting frame 6. The protective plate 7, specifically the chest protective plate 7, can rotate around the connection point at the top of the mounting frame 6. When using the transfer frame, it can be adjusted according to the user's chest position and posture to provide protection. Two protective rods 8 are rotatably connected to both sides of the mounting frame 6. The rotatable connection between the protective rods 8 and the mounting frame 6 provides a movable joint for the protective structure of the transfer frame. During use, it can automatically tighten to protect the patient. A connecting plate 2 11 is fixedly connected between two adjacent protective rods 8, connecting the two adjacent protective rods 8 into a whole, enhancing the protection of this part. To ensure the stability of the protective structure, a rotating plate 12 is rotatably connected to the front of the connecting plate 11. The rotating plate 12 can rotate around the connection point with the connecting plate 11. In the self-tightening mechanism of the shift frame, the rotating plate 12 plays the role of transmitting and converting force. A connecting rod 14 is rotatably connected to the end of the rotating plate 12 away from the connecting plate 11. The connecting rod 14 is responsible for further transmitting and guiding the transmitted force to the rotating plate 12. A ball 15 is fixedly connected to the side of the connecting rod 14 away from the rotating plate 12. The ball 15 is used to slide and drive the connecting rod 14 to rotate, further realizing the effect of automatic tightening.

[0030] Reference Figure 1 and Figure 2 The outer wall of the protective bar 8 is covered with a sponge sleeve 9, which provides a soft touch for the user and acts as a buffer when the user's body comes into contact with the protective bar 8, so as to avoid discomfort or injury caused by direct contact with the hard protective bar 8.

[0031] Reference Figure 1 and Figure 2A restraint strap 10 is installed between the two bottom protective bars 8. The restraint strap 10 can restrain the user's legs to prevent the user from slipping off the transfer frame due to body swaying or changes in posture.

[0032] Reference Figure 1 A standing plate 2 is fixedly connected between the rear of the two base frames 1. The standing plate 2 provides a platform for the user to stand on. When using the transfer frame, it provides support for the patient's feet when squatting down, ensuring safety during the transfer process.

[0033] Reference Figure 2 A hydraulic push rod 13 is rotatably connected between the front parts of the two base frames 1. The output end of the hydraulic push rod 13 is rotatably connected to the bottom of the mounting frame 6. The hydraulic push rod 13 can be powered by external control. When the hydraulic push rod 13 is started, its output end pushes the mounting frame 6 to move, thereby adjusting the position of the mounting frame 6 to meet the needs of different patients to comfortably adapt to the effect of the transfer frame.

[0034] Reference Figure 3 The connecting rod 14 is rotatably connected to the front of the mounting frame 6, ensuring that the chest protection plate 7 can effectively drive the connecting rod 14 to rotate during the compression of the ball 15, and further drive the subsequent rotating plate 12 and connecting plate 11 to rotate, thereby achieving the protective effect on the patient.

[0035] Reference Figure 4 The chest protector 7 and the ball 15 are in contact, ensuring that the ball 15 can effectively push the chest protector 7 to slide when squeezed by the patient.

[0036] Working principle: When it is necessary to relocate a patient with limited mobility, the hydraulic push rod 13 is activated. After activation, the hydraulic push rod 13 extends and retracts, thereby driving the mounting frame 6 to rotate. This further drives the handrail 5 and connecting plate 4 to rotate along the top of the support frame 3, allowing the relocation frame to place the patient in a comfortable environment. Subsequently, the restraint strap 10 is removed, and the patient is transferred to the standing board 2. Then, the patient lies face down on the chest protection plate 7. When the patient lies face down on the chest protection plate 7, the pressure exerted by the patient's own weight will cause the chest protection plate 7 to rotate along the top of the support frame 3. The top of the mounting frame 6 rotates, which compresses the ball 15, causing the connecting rod 14 to rotate. When the connecting rod 14 rotates, it applies an outward pushing force to the rotating plate 12, further causing the connecting plate 11 to rotate, which in turn causes the four protective rods 8 to rotate inward, thus surrounding the patient and ensuring a safe environment during the relocation process. Subsequently, the restraint straps 10 are fixed to protect the patient's legs. Finally, the staff pulls the handrail 5 to relocate the patient.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
