[0027] like Figure 1 、 Figure 2As shown, an embodiment of the present invention provides a multifunctional stretcher suitable for use in narrow corridors, comprising a stretcher assembly, a frame assembly, a front wheel assembly, a rear wheel assembly, and an auxiliary wheel assembly. The stretcher assembly and the frame assembly are hingedly connected, and the front and rear wheel assemblies are also hingedly connected to the frame assembly, enabling rotation relative to the frame assembly to adjust the applicable state of the multifunctional stretcher. The auxiliary wheel assembly is fixed. Therefore, the frame assembly can be considered a base for state adjustment. The frame assembly is provided with multiple adjustment mechanisms, which are used to adjust the angles of the stretcher assembly, the front wheel assembly, and the rear wheel assembly relative to the frame assembly.

[0028] In this embodiment, the stretcher assembly includes a stretcher body 1, which is provided with a plurality of handrails 2. The handrails 2 are distributed on both sides of the upper surface of the stretcher body 1. On the one hand, they facilitate hand-held transportation and provide a secure grip for the person lying on the stretcher body 1. On the other hand, they also limit the position of the person lying on the stretcher body 1 to prevent the person from rolling off and causing secondary injury.

[0029] In this embodiment, the frame assembly includes side panels 3. Considering the form of the stretcher body 1, the side panels 3 are arranged on either side of the stretcher body 1 and connected by multiple crossbars 4 to form a monolithic structure. Pin holes are provided on both sides of the stretcher body 1 and the side panels 3 at corresponding locations. Connecting pins 5 enable the stretcher body 1 and the side panels 3 to be hinged together, allowing the stretcher body 1 to rotate relative to the side panels 3.

[0030] The stretcher body 1 is driven by a first electric push rod 6 to adjust its angle. The base of the first electric push rod 6 is hinged to the cross bar 4, and the telescopic end of the first electric push rod 6 is hinged to the lower surface of the stretcher body 1. Therefore, the angle of the stretcher body 1 relative to the frame assembly can be adjusted by extending and retracting the telescopic end of the first electric push rod 6.

[0031] In this embodiment, two front and rear wheel assemblies are provided, one for each frame side panel 3. Specifically, the front wheel assembly includes a front wheel connecting rod 7 and a front rolling wheel 8. The first end of the front wheel connecting rod 7 is hinged to the frame side panel 3, and the second end of the front wheel connecting rod 7 is hinged to the front rolling wheel 8, and the front rolling wheel is in a freely rotating state. The rear wheel assembly includes a rear wheel connecting rod 9 and a rear rolling wheel 10. The first end of the rear wheel connecting rod 9 is hinged to the frame side panel 3, and the second end of the rear wheel connecting rod 9 is hinged to the rear rolling wheel 10, and the rear rolling wheel 10 is in a freely rotating state.

[0032] The front wheel link 7 is driven to adjust its angle by a second electric push rod 11. The base of the second electric push rod 11 is hinged to the frame side panel 3, and the telescopic end of the second electric push rod 11 is hinged to the front wheel link 7. The rear wheel link 9 is driven to adjust its angle by a third electric push rod 12. The base of the third electric push rod 12 is hinged to the frame side panel 3, and the telescopic end of the third electric push rod 12 is hinged to the rear wheel link 9. Therefore, by extending and retracting the telescopic ends of the second and third electric push rods 11 and 12, the angles of the front wheel link 7 and the rear wheel link 9 relative to the frame assembly are adjusted respectively.

[0033] It should be noted that in this embodiment, a crossbar 4 can be provided between the two front wheel connecting rods 7 to maintain synchronous movement, or the crossbar 4 can be omitted and the two second electric push rods 11 can be used to drive the two front wheel connecting rods separately. The same is true for the rear wheel connecting rods, which will not be described in detail here. In addition, the electric push rods can also be replaced with cylinders or other types of linear drive components. Those skilled in the art can make their choice based on limited testing.

[0034] In this embodiment, multiple auxiliary wheel assemblies are also provided, including auxiliary wheel connecting rods 13 and auxiliary rolling wheels 14. The first ends of the auxiliary wheel connecting rods 13 are fixedly connected to the frame side panels 3, and the second ends of the auxiliary wheel connecting rods 13 are hingedly connected to the auxiliary rolling wheels 14, and the auxiliary rolling wheels 14 are in a freely rotating state. As a preferred embodiment, in this embodiment, two sets of auxiliary wheel assemblies are also provided at the front end of the stretcher body 1, that is, the entire device is equipped with four sets of auxiliary wheel assemblies to provide more secure support.

[0035] The auxiliary wheel link 13 is orthogonal to the frame side plate 3 or the stretcher body 1, and the front wheel link 7 and the rear wheel link 9 can be adjusted in angle. Figure 1 When it is supported on a horizontal plane in a normal state (when the second electric push rod 11 is extended to the limit and the third electric push rod 12 is shortened to the limit), the frame side plate 3 can be kept horizontal. At this time, the first electric push rod 6 of the stretcher body 1 is shortened to the limit so that the stretcher body 1 can also be kept horizontal, thereby facilitating the transportation of people onto the stretcher body 1. At this time, the auxiliary rolling wheel 14 has a height difference relative to the front rolling wheel 8 and the rear rolling wheel 10, and does not contact the ground and does not play a supporting role.

[0036] At the same time Figure 3As shown, when the device needs to pass through the step surface, such as going down a narrow staircase or lifting it into the compartment of an ambulance, the second electric push rod 12 is shortened to the limit, so that the front wheel connecting rod 7 and the front rolling wheel 8 are retracted relative to the frame side plate 3, so that the device can be supported by the rear rolling wheel 10 and the auxiliary rolling wheel 14. Due to the height difference between the auxiliary rolling wheel 14 and the rear rolling wheel 10, it can be supported on steps of different heights of the stairs, so that the frame side plates 3 and the stretcher body 1 remain level, ensuring that the person will not shake or even fall, and move down step by step with the assistance of the carrier (slightly lift and then move horizontally before putting down), so that the carrier can save more effort.

[0037] At the same time Figure 4 As shown, when the device needs to be lifted into the compartment of the ambulance, on the basis of the above, the stretcher body 1 is pushed into the compartment, and at the same time the third electric push rod 12 is extended to the extreme position, so that the rear wheel connecting rod 9 and the rear rolling wheel 10 are retracted relative to the frame side plate 3, so that the stretcher body 1 can continue to be pushed into the compartment until the rear rolling wheel 10 is flush with the auxiliary rolling wheel 14 and contacts the bottom surface of the compartment, and then the stretcher body 1 can be further pushed.

[0038] At the same time Figure 5 As shown, when the device needs to be moved into a narrow elevator car, the second electric push rod 11 is extended to its limit and the third electric push rod 12 is shortened to its limit, so that the frame side panels 3 remain horizontal. The first electric push rod 6 of the stretcher body 1 is extended to the appropriate position to tilt the stretcher body 1 relative to the frame side panels 3, thereby enabling it to enter the narrow elevator car at an angle. At this time, the person is in a reclining position and can hold the handrail 2 or have a carrier assist to ensure they do not fall. This method can also be used when turning in a narrow corridor.

[0039] In summary, the multifunctional stretcher provided in this embodiment can be conveniently adjusted to different postures through the arrangement of the stretcher assembly, frame assembly, front wheel assembly, rear wheel assembly and auxiliary wheel assembly to adapt to different personnel transporting scenarios, including transporting personnel onto the stretcher body 1, passing through narrow stairs, lifting into the ambulance compartment, entering a narrow elevator compartment, etc., which significantly improves the convenience and efficiency of personnel transport and reduces the labor intensity of the transporter. It is particularly suitable for the transport and transfer of personnel in old communities.

[0040] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
