Description

Technical Field

[0001] The utility model relates to the technical field of medical expansion vehicles, in particular to an expansion compartment structure of an expansion medical vehicle. Background Art

[0002] The medical expansion vehicle is a special vehicle with expandable compartment space. By expanding the compartment, the usable area inside the vehicle is increased, making it easier for medical staff to perform medical work outside the hospital. The main compartment and expansion compartment structural principles of existing different types of medical vehicles are similar. Through the driving and guiding mechanism of the medical expansion vehicle itself, the expansion compartment is driven to move horizontally outward from the inside of the main compartment, thereby increasing the internal space and facilitating more medical work.

[0003] The existence of the extended compartment floor is a prerequisite for the normal placement of medical tools and equipment, standing and load-bearing after the extended compartment is extended out of the main compartment. Therefore, no matter what kind of extended medical vehicle is currently on the market, the extended compartment floor cannot be made hidden. Therefore, after being retracted to the main compartment, the extended compartment floor will form a raised step on the floor of the main compartment, which is not on the same plane as the floor of the main compartment, making it inconvenient to place medical equipment. There are deficiencies that need to be improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an expansion compartment structure of an expandable medical vehicle, which is used to solve the problem that when the main compartment of the existing medical expansion vehicle is not expanded, the floor of the expanded compartment forms a step and is not in the same plane as the floor of the main compartment, making it inconvenient to place medical equipment.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] An expansion compartment structure of an expansion medical vehicle comprises a main compartment and an expansion compartment installed on the side of the main compartment and capable of being telescopically expanded, wherein a compartment flipping bottom plate that flips through a hinge is provided at the bottom of the expansion compartment, and a supporting flange supported below the edge of the compartment flipping bottom plate is provided at the edge of the expansion compartment bottom plate, connecting plates extending toward the inner side wall of the expansion compartment are fixedly connected on both sides of the compartment flipping bottom plate, and a wire draw box is fixedly installed at a position near the back of the inner wall on both sides of the inner wall of the expansion compartment, and the telescopic end of the steel wire draw rope of the wire draw box is fixedly connected to the connecting plate;

[0014] Preferably, the squeeze-to-open button is located on the front side of the extended compartment floor near the bottom.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The compartment flip floor of the expansion compartment of the utility model can be flipped upward around the hinge. When the expansion compartment is not expanded outward, the bottom of the expansion compartment is ensured to be at the same height as the bottom of the main compartment, which is convenient for placing medical equipment, medical beds and other facilities, bringing convenience to use. It solves the problem of the existing medical expansion vehicle that when the main compartment is not expanded, the expansion compartment floor forms a step and is not in the same plane as the bottom of the main compartment, making it inconvenient to place medical equipment.

[0017] (2) When the expansion compartment of the utility model does not expand outward and the compartment flip floor needs to be flipped upward for storage, especially when a medical bed is pushed in from the outside for rescue, the medical staff walking at the head and foot of the bed can kick and squeeze the opening button at the same time, which can drive the positioning pin to contract and separate from the clearance groove of the compartment flip floor. The compartment flip floor is pulled upward for storage by the steel wire under the action of the pull box, so that the medical bed can be parked in the expansion compartment on the side of the main compartment to carry out rescue work without touching the compartment flip floor with hands. It is not only convenient to flip and store the compartment flip floor, but also does not require medical staff to touch it with their hands during rescue, ensuring clean and hygienic rescue, and has strong practicality.

[0028] A limit pulley 11 is installed on the inner wall of the expansion compartment 2 at a position below the cable box 6. The steel wire rope 601 of the cable box 6 passes around the bottom of the limit pulley 11 and is connected to the connecting plate 5. The wheel axle of the limit pulley 11 is fixedly connected with an anti-drop buckle 4 sleeved on the surface of the steel wire rope 601. The distance between the limit pulley 11 and the bottom plate of the expansion compartment 2 is not less than the width of the compartment flip bottom plate 202.

[0029] Positioning grooves 203 are provided at positions near the front on both sides of the car flipping bottom plate 202, and positioning pins 7 are laterally movably inserted in the positioning grooves 203. The positioning pins 7 are movably inserted and installed inside the bottom plate of the extended car 2, and a positioning spring 8 is installed at the end of the positioning pin 7 away from the car flipping bottom plate 202.
