Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device transportation equipment technology, specifically to an anti-tipping structure for a medical device transport vehicle. Background Technology
[0002] In hospitals and other medical facilities, medical device transport vehicles are commonly used to move various medical devices, medicines, and other supplies. However, existing medical device transport vehicles have many problems in actual use.
[0003] On the one hand, when transport vehicles travel on uneven ground, or during turns or sudden stops, their high center of gravity makes them prone to tipping over, potentially damaging medical devices and even causing medical accidents, resulting in serious economic losses and adverse effects. On the other hand, existing transport vehicles lack stable support structures during loading and unloading of medical devices, making it difficult to guarantee safety and stability during the process. Furthermore, some transport vehicles have unreasonable structural designs, making operation inconvenient and affecting work efficiency. Therefore, there is an urgent need for a tipping-proof structure for medical device transport vehicles that can effectively prevent tipping, improve loading and unloading stability, and enhance operational convenience.
[0004] In view of this, we propose an anti-tipping structure for medical device transport vehicles. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides an anti-tipping structure for a medical device transport vehicle.
[0006] The technical solution of this utility model is:
[0007] The anti-tipping structure of the medical device transport vehicle includes two compartments stacked one on top of the other, which are fixedly connected by support columns at the four corners. Each compartment has a flap that can be folded down on its front outer wall. A support leg is fixedly installed at each of the four corners of the bottom of the lower compartment, and a first omnidirectional wheel is fixedly installed at the bottom of each support leg. An auxiliary wheel assembly is hinged to the outside of each support leg. The auxiliary wheel assembly includes a retractable support component and a second omnidirectional wheel fixedly installed at the bottom of the support component. When the support component rotates to a certain angle and extends to a certain length, the second omnidirectional wheel is perpendicular to the ground and its bottom is flush with the first omnidirectional wheel.
[0008] As a preferred technical solution, a U-shaped handle is fixedly connected to the top of the upper compartment to facilitate medical staff in pushing the transport vehicle.
[0009] As a preferred technical solution, a support bar is fixedly connected to the outer wall of the carriage at the bottom of the flip-up plate, and when the flip-up plate contacts the top of the support bar, the flip-up plate is horizontal, providing support for the flip-up plate and facilitating the loading and unloading of medical devices.
[0010] As a preferred technical solution, when the flap is horizontal, its top is flush with the bottom of the carriage. Two pins are symmetrically provided on the flap. When the flap is vertical, both pins are connected to the carriage to ensure the stability of the flap in the vertical state and prevent it from accidentally flipping over.
[0011] As a preferred technical solution, the support assembly includes an upper connecting block and a lower inclined block. The second universal wheel is installed at the bottom of the inclined block. An electric telescopic rod with an output shaft fixedly connected to the connecting block is fixedly installed at the top of the inclined block. A power box for storing a battery is fixedly installed at the bottom of the lower compartment. The battery is electrically connected to the electric telescopic rod through a wire. The extension and retraction of the auxiliary wheel assembly is controlled by the electric telescopic rod, making the operation convenient and quick.
[0012] As a preferred technical solution, two mounting plates are symmetrically fixedly connected to the outer wall of each support leg. The connecting block is located between the two mounting plates, and a limiting pin is provided between the two mounting plates. The limiting pin is plugged into the mounting plate, and a fixing bolt is threaded on the limiting pin to limit the position of the limiting pin, so as to ensure that the auxiliary wheel assembly can be stably fixed after rotating to a suitable angle.
[0013] As a preferred technical solution, the limiting pin has a polygonal cross-section, which ensures that the second universal wheel is perpendicular to the ground. When the support assembly is rotated so that the second universal wheel is perpendicular to the ground and the piston rod of the electric telescopic rod is extended to its longest length, the bottom of the second universal wheel is flush with the bottom of the first universal wheel, ensuring that the auxiliary wheel assembly can effectively prevent tipping.
[0014] As a preferred technical solution, a counterweight is fixedly installed at the bottom of the lower compartment to lower the center of gravity and further improve the stability of the transfer vehicle.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. By setting up an auxiliary wheel assembly, when the transport vehicle needs to load or unload medical devices or travel on unstable roads, the auxiliary wheel assembly can be rotated and extended, so that the second universal wheel and the first universal wheel jointly support the transport vehicle, increasing the support area, effectively preventing the transport vehicle from tipping over, and improving the stability of the transport vehicle under various working conditions.
[0017] 2. The flip-up structure of this utility model can be folded down and opened to form a flat operating platform flush with the bottom of the vehicle when loading and unloading medical devices, which facilitates the handling and placement of medical devices and improves the convenience and safety of loading and unloading.
[0018] 3. By installing a counterweight at the bottom of the lower compartment, this utility model lowers the center of gravity of the transport vehicle, further enhancing its stability and reducing the risk of tipping over. At the same time, the U-shaped handle design is ergonomic, making it easier for medical staff to push the transport vehicle, thus improving operational comfort and work efficiency.

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.
[0026] Please see Figures 1-4 This utility model provides a technical solution:
[0027] like Figures 1-3As shown, the anti-tipping structure of the medical device transport vehicle includes two stacked compartments 100, which are fixedly connected by support columns 800 located at the four corners. The support columns 800 ensure a stable connection and structural strength between the upper and lower compartments 100. Each compartment 100 has a hinged flap 101 on its front outer wall that can be folded down and opened. In use, the flap 101 can be opened, and the medical device can be placed inside the compartment 100 to prevent it from falling out. A support leg 300 is fixedly installed at each of the four corners of the bottom of the lower compartment 100. Each support leg 300 has a first omnidirectional wheel 400 fixedly installed at its bottom for easy movement of the transport vehicle. An auxiliary wheel assembly 500 is hinged to the outer side of each support leg 300. The auxiliary wheel assembly 500 includes a retractable support component and a second omnidirectional wheel 502 fixedly installed at the bottom of the support component. The auxiliary wheel assembly 500 can provide diagonal bracing for the transfer vehicle, which can effectively prevent the transfer vehicle from tilting.
[0028] like Figure 2 As shown, in a preferred embodiment, a support bar 102 is fixedly connected to the bottom of the flap 101 on the outer wall of the carriage 100. When the flap 101 is folded down to contact the top of the support bar 102, the flap 101 is in a horizontal state. At this time, the top of the flap 101 is flush with the bottom of the carriage 100, forming a flat loading and unloading platform. The pin 103 is provided to fix the flap 101 to the carriage 100 when the flap 101 is vertical.
[0029] like Figure 4 As shown, in a preferred embodiment, the support assembly includes a connecting block 506 located above and a ramp 501 located below. A second universal wheel 502 is installed at the bottom of the ramp 501. An electric telescopic rod 507 with an output shaft fixedly connected to the connecting block 506 is fixedly installed at the top of the ramp 501. A power box 600 for storing a battery is fixedly installed at the bottom of the lower compartment 100. The battery is electrically connected to the electric telescopic rod 507 via wires. Two mounting plates 503 are symmetrically fixed to the outer wall of each support leg 300. A connecting block 506 is located between the two mounting plates 503. A limiting pin 504 is provided between the two mounting plates 503, and the limiting pin 504 is plugged into the mounting plate 503. A fixing bolt 505 is threaded on the limiting pin 504. The limiting pin 504 has a polygonal cross-section, which ensures that the second omnidirectional wheel 502 is perpendicular to the ground. When the support assembly is rotated so that the second omnidirectional wheel 502 is perpendicular to the ground and the piston rod of the electric telescopic rod 507 is extended to its maximum length, the bottom of the second omnidirectional wheel 502 is flush with the bottom of the first omnidirectional wheel 400. The auxiliary wheel assembly 500, which can be extended and retracted, is provided, which increases the convenience of use, especially since it can be folded and stored when not in use.
[0030] like Figure 1 As shown, in a preferred embodiment, a U-shaped handle 200 is fixedly connected to the top of the upper compartment 100 to facilitate medical staff in pushing the transport vehicle; a counterweight 700 is fixedly installed at the bottom of the lower compartment 100 to lower the center of gravity and improve the stability of the transport vehicle.
[0031] When using the anti-tipping structure of this utility model's medical device transport vehicle, to load or unload medical devices, the flap 101 is first folded downwards so that it contacts the support bar 102, and the flap 101 is placed in a horizontal position to form a loading and unloading platform, facilitating the placement or removal of medical devices from the vehicle compartment 100. When the transport vehicle is moving, the auxiliary wheel assembly 500 can be rotated to make the second universal wheel 502 rotate perpendicular to the ground. Then, the battery in the power box 600 supplies power to the electric telescopic rod 507, controlling its extension so that the bottom of the second universal wheel 502 is flush with the bottom of the first universal wheel 400. At this time, the second universal wheel 502 and the first universal wheel 400 jointly support the transport vehicle, increasing the support area and effectively preventing the transport vehicle from tipping over.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
