Description

Technical Field

[0001] The utility model relates to the technical field of stretchers, in particular to a stretcher which is easy to store. Background Art

[0002] A stretcher is a medical transport tool designed specifically for patients with limited mobility or injuries. The stretcher equipped in ambulances meets the needs of the disease and is convenient for patients and injured to lie down. It is usually made of high-strength materials and has the characteristics of portability, stability and safety. It can help medical staff quickly and effectively transfer patients from one place to another. It is an indispensable and important equipment in medical first aid, disaster relief, sports events and outdoor activities, military and battlefield rescue, and special environment rescue.

[0003] Stretchers play a vital role in medical emergency and patient transfer. In hospitals, stretchers are used to transfer patients between different departments, such as from the emergency room to the operating room, from the ward to the examination room, etc., to ensure the safety and comfort of patients during the movement within the hospital. Most stretchers used in hospitals usually have universal wheels, so that heavier patients or patients who are inconvenient to move can be transported on stretchers, which effectively solves the problem of the heavy weight of the stretcher itself and the effort required to carry it.

[0004] Most stretchers can only retract the leg area of ​​the frame, and cannot be further stored when not in use, resulting in the stretcher still occupying a large space in the ambulance, affecting the movement of medical staff in the ambulance. Therefore, a stretcher that is easy to store is proposed to solve the above problem. Utility Model Content

[0025] The storage structure 4 includes a limiting plate 401, the bottom of the movable plate 3 is fixedly installed with the limiting plate 401, the external rotatable installation of the limiting plate 401 is provided with a screw rod 402, the external thread of the screw rod 402 is connected to a threaded block 403, the bottom of the threaded block 403 is fixedly installed and hinged with a hinged rod 404, the bottom of the movable plate 3 is fixedly installed with a mounting block 405, the bottom of the mounting block 405 is rotatably installed with a support rod 406, and the bottom of the support rod 406 is provided with a universal wheel 407.

[0026] exist Figure 2 When the two movable panels 3 are unfolded, the first connecting panel 208 and the second connecting panel 210 are close to and fit together, thereby forming a supporting force to keep the two movable panels 3 and the main panel 1 balanced.

[0027] exist Figure 5 In the embodiment, the screw rod 402 and the threaded block 403 drive the hinge rod 404. When the support rod 406 plays a supporting role, the self-locking function of the screw rod 402 and the threaded block 403 can prevent the support rod 406 from shaking.

[0028] exist Figure 2 In the embodiment, a handle 5 is provided on each side of the two movable panels 3 away from the main panel 1 , and the handle 5 can be used to move the movable panels 3 and the main panel 1 when the storage structure 4 is folded.

[0029] exist Figure 3 In the figure, the fixed rod 202 passes through the movable ring 203 and is movably connected to the movable ring 203. The movable ring 203 is limited by the fixed rod 202, and the turntable 206 is rotatably connected to the movable ring 203 through the bearing, so that the turntable 206 will not be separated from the movable ring 203 when it rotates.

[0030] exist Figure 4In the figure, the rotating rod 207 passes through the connection box 201 and extends to the outside of the connection box 201. There are two connection boxes 201, and the other connection box 201 is located on the left and right sides of the front end of the main board 1. The rotating rod 207 passes through the first ring 209 and is fixedly connected to the first ring 209. When the rotating rod 207 rotates, it will drive the first ring 209 and the first connecting plate 208 to rotate at the same time.

[0031] exist Figure 4 In the embodiment, the rotating rod 207 passes through the second ring 211 and is movably connected to the second ring 211. When the rotating rod 207 rotates, it will not have a linkage effect with the second ring 211. At the same time, the rotating rod 207 is limited by the second connecting plate 210 and the second ring 211. The rotating rod 207 passes through the fixed plate 212 and is fixedly connected to the fixed plate 212.

[0032] exist Figure 5 In the embodiment, the bottom of the hinged rod 404 is hinged to the support rod 406, and the hinged rod 404 allows the threaded block 403 to be linked with the support rod 406 when it moves, and a slider is fixedly installed on the top of the threaded block 403.

[0033] exist Figure 5 In the embodiment, a sliding groove is provided at the bottom of the movable plate 3, and the slider is slidably connected to the sliding groove. The slider and the sliding groove can limit the threaded block 403 when the threaded block 403 moves.

[0034] During implementation, the following steps are performed: when in use, first rotate the screw 402, and the support rod 406 is driven to rotate around the mounting block 405 through the movement of the hinged rod 404, so that the four universal wheels 407 can be stored, and the support rod 406 will be close to the bottom of the movable plate 3. After pulling the rotating rod 207, the rotating rod 207 is rotated again to drive the movable plate 3 to move. The two rotating rods 207 will drive the two movable plates 3 to move to the left and right sides under the main board 1, so that the stretcher can be stored into a rectangular parallelepiped. Finally, push the rotating rod 207 to engage the second crown gear 205 with the first crown gear 204, so that the folded movable plate 3 can be limited to prevent the movable plate 3 from shaking, thereby saving more floor space.

[0035] In summary, when the stretcher body needs to be stored, the rotating rod 207 is first pulled to make the turntable 206 drive the second crown gear 205 to disengage from the first crown gear 204, thereby rotating the rotating rod 207, which can drive the first connecting plate 208, the movable plate 3 and the fixed plate 212 to move around the main plate 1 through the first ring 209. When the two movable plates 3 are close to each other and in a vertical state, the rotating rod 207 is pushed to make the second crown gear 205 and the first crown gear 204 engage, so that the folded stretcher body can be limited. To prevent the movable plate 3 from shaking, the screw rod 402 is rotated to drive the threaded block 403 to move, so that the hinged rod 404 drives the support rod 406 to rotate around the mounting block 405 until the support rod 406 approaches the bottom of the movable plate 3. The stretcher support legs can be stored, which solves the problem that most stretchers can only perform a single contraction of the leg area of ​​the bracket and cannot be further stored when not in use, resulting in the stretcher still occupying a large space in the ambulance, affecting the movement of medical staff in the ambulance.
