Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary medical equipment, in particular to a deployable medical rescue vehicle. Background Art

[0002] The rescue vehicle is an essential auxiliary equipment for each department of the hospital. It is used to store rescue items such as rescue medicines and medical tools, so that the rescue items can be quickly collected to the rescue site by pushing the rescue vehicle. When implementing rescue, in order to ensure timely rescue, the rescue items in the rescue vehicle must be clearly visible and quickly accessible. The medical rescue vehicle currently used is a simple cabinet structure, which includes a vehicle body, and a number of wheels are arranged at the bottom of the vehicle body to facilitate the movement of the vehicle body; the vehicle body is divided into two layers, the lower part of the vehicle body is provided with a storage compartment for placing medical waste recycling barrels and cleaning tools, etc., the upper part of the vehicle body is formed with a storage box for placing rescue items such as rescue medicines and tools, and the top of the vehicle body is provided with a cover plate that can be flipped over. The top of the storage box is open. When it is not needed, the cover plate is buckled on the top of the vehicle body to close the opening of the storage box. When rescue is needed, the cover plate can be opened to open the storage box for easy viewing and access to rescue items.

[0003] In existing emergency vehicles, emergency items are placed in storage boxes. In the process of emergency treatment for certain diseases, many types of emergency items are needed, which leads to the items in the storage boxes being stacked in a messy manner and not being clear at a glance, which is not conducive to the implementation of emergency treatment in a hurry. To solve this problem, departments that use more emergency items are generally equipped with larger capacity emergency vehicles, but the corresponding emergency vehicles are larger in size and take up more space when not in use.

[0004] In the prior art, there is also a multi-layer rescue vehicle, which is provided with one or more drawer boxes below the storage box, so that more rescue items can be stored without increasing the horizontal space occupation. When implementing the rescue, the cover of the rescue vehicle is opened and the drawer box is pulled out to facilitate the viewing and taking of the rescue items. In actual application, since the drawer box can slide freely, there is a situation where the drawer box is pushed back by mistake when taking the items in the drawer box; and because there is a height difference between the drawer box and the storage box, when taking the rescue items in the drawer box, it is necessary to bend down slightly to take it, which is not conducive to taking it at hand to a certain extent. In addition, the rescue items in the rescue vehicle are generally equipped in advance. In order to avoid other patients or medical staff from taking them by mistake and causing a shortage of rescue items when rescue is needed, the rescue vehicle is usually locked when not in use. After the rescue vehicle with this multi-layer structure is equipped with the rescue items, the storage box and the drawer box need to be locked separately, and they need to be unlocked separately before implementing the rescue, and the locking and unlocking process is also relatively troublesome.

Specific embodiments

[0026] The technical solutions of the present utility model will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0027] As Figures 1 to 7 shown, a deployable medical rescue vehicle includes a vehicle body 1, a plurality of wheels 2 are provided at the bottom of the vehicle body 1, a storage compartment 3 is opened in the lower part of the vehicle body 1, a cover plate 4 is buckled on the top of the vehicle body 1, and the rear end of the cover plate 4 is rotatably connected to the top of the vehicle body 1. On this basis, a link mechanism, a lifting box 5 and two drawer mechanisms are further provided. The drawer mechanism includes a drawer box 6, and the two drawer boxes 6 are symmetrically arranged in the upper part of the vehicle body 1, and the two drawer boxes 6 can slide out in the two side directions of the vehicle body 1 respectively. The link mechanism includes a swing rod 7, a connecting rod 8, a push rod 9 and a slider 10. One end of the swing rod 7 is fixedly connected to the rear end of the cover plate 4, the other end of the swing rod 7 is rotatably connected to one end of the connecting rod 8, the other end of the connecting rod 8 is rotatably connected to one end of the push rod 9, the rod body of the push rod 9 is rotatably connected to the vehicle body 1, the other end of the push rod 9 is rotatably connected to the slider 10, the slider 10 is slidably connected to the bottom of the lifting box 5, and the lifting box 5 is slidably arranged in the middle of the vehicle body 1.

[0028] When the deployable medical rescue vehicle is in use, the lifting box 5 and the drawer box 6 are filled with rescue drugs, medical tools, etc. In the retracted state as Figures 1 to 3 shown, the cover plate 4 is buckled on the top of the vehicle body 1, the lifting box 5 is retracted into the middle of the vehicle body 1, and the drawer box 6 is retracted into the upper part of the vehicle body 1. At this time, the volume and floor space of the entire rescue vehicle are relatively small. When rescue needs to be carried out, as Figures 4 to 6As shown in the figure, first pull out the two drawer boxes 6 to both sides of the vehicle body 1, and then turn over the cover plate 4. When the cover plate 4 is turned over, the swing rod 7 rotates together. The other end of the swing rod 7 drives one end of the push rod 9 to rotate downward through the connecting rod 8, and the other end of the push rod 9 jacks up the lifting box 5 through the slider 10 until the cover plate 4 is completely opened. The lifting box 5 rises to the same height as the drawer box 6 and is located between the two drawer boxes 6. In the open state of the cover plate 4, the lifting box 5 and the two drawer boxes 6 are on the same plane, and the rescue items inside can be clearly seen and easily taken, which is conducive to implementing rescue against time. One end of the drawer box 6 located inside the rescue vehicle is limited by the lifting box 5, and the drawer box 6 will not retract during the rescue process. When it needs to be retracted, when the cover plate 4 is turned downward to close it, the lifting box 5 descends to the middle of the vehicle body 1 under the drive of the linkage mechanism, and then the drawer box 6 is pushed back into the vehicle body 1. The unfolding and retracting processes of the entire rescue vehicle are relatively convenient.

[0029] Furthermore, the drawer mechanism further includes a limiting plate 11, a spring 12 and a lock. The limiting plate 11 is fixedly arranged at one end of the drawer box 6 located inside the vehicle body 1. When the drawer box 6 is completely pulled out, the limiting plate 11 abuts against the inner wall of the vehicle body 1 to limit the drawer box 6 and prevent the drawer box 6 from completely coming out. One end of the spring 12 is connected to the limiting plate 11, and the other end of the spring 12 is connected to the vehicle body 1. The spring 12 is used to provide the elastic force for the drawer box 6 to slide out of the vehicle body 1. The lock is used to limit the drawer box 6 when the drawer box 6 is retracted into the vehicle body 1. When rescue needs to be implemented, unlock the lock on the drawer box 6, and the drawer box 6 can quickly pop out under the action of the spring 12. At the same time, the spring 12 presses the limiting plate 11 against the inner wall of the vehicle body 1 to avoid interfering with the rising of the lifting box 5.

[0030] Furthermore, an inclined surface is provided at the top of the limiting plate 11. The above-mentioned lock is similar to the structure of a cow head lock. For example, Figure 7As shown in the figure, it includes a sliding seat 13, a sliding tongue 14 and a conical spring 15. The sliding seat 13 is fixedly arranged on the bottom surface of the cover plate 4. The sliding tongue 14 is slidably connected to the sliding seat 13. One end of the conical spring 15 is connected to the sliding seat 13, and the other end of the conical spring 15 is connected to one end of the sliding tongue 14. The other end of the sliding tongue 14 is adapted to the inclined surface at the top of the limiting plate 11. This setting can make the deployment and retraction of the rescue vehicle more convenient. Specifically: when it is necessary to retract the rescue vehicle, first close the cover plate 4, lower the lifting box 5 to the middle of the vehicle body 1 to release the limit on the retraction of the drawer box 6. At this time, the cover plate 4 is buckled on the top of the vehicle body 1, and the sliding tongue 14 is vertically arranged; then push the drawer box 6 back into the vehicle body 1 and compress the spring 12. During the retraction process of the drawer box 6, when the inclined surface at the top of the limiting plate 11 contacts the sliding tongue 14, the sliding tongue 14 can be pushed up and the conical spring 15 is compressed. When the limiting plate 11 passes over the position of the sliding tongue 14, the sliding tongue 14 resets under the action of the conical spring 15. At this time, the protruding sliding tongue 14 locks and limits the side of the limiting plate 11 close to the drawer box 6, and the drawer box 6 cannot pop out. When it is necessary to deploy the rescue vehicle, turn the cover plate 4 upward. In the first half of the process of turning over the cover plate 4, the lock follows the cover plate 4 and moves upward together until the sliding tongue 14 separates from the limiting plate 11. Under the action of the spring 12, the two end drawer boxes 6 are directly ejected. As the cover plate 4 continues to be turned over, under the drive of the link mechanism, the lifting box 5 is raised to the position between the two drawer boxes 6. Thus, the entire deployment operation of the rescue vehicle is completed by turning over the cover plate 4.

[0031] Further, a hanging plate 16 is rotatably connected to the front end of the cover plate 4. When operating, the cover plate 4 can be turned over by holding the hanging plate 16. A hanging hole 17 is provided on the hanging plate 16, and a lock plate 18 is fixedly arranged on the vehicle body 1. After the cover plate 4 is buckled, the hanging plate 16 can be turned downward so that the lock plate 18 passes through the hanging hole 17. A padlock can be installed on the lock plate 18 to lock the cover plate 4. According to the above, when the cover plate 4 is buckled, the drawer box 6 can be locked by the lock on the bottom surface of the cover plate 4. It can be seen that installing a padlock can lock the entire rescue vehicle, which is convenient for the management of the rescue vehicle.

[0032] In the specific implementation, a rotating shaft 19 is rotatably arranged on the vehicle body 1. The rear end of the cover plate 4 and one end of the swing rod 7 are both fixedly sleeved on the rotating shaft 19. The cover plate 4 is rotatably connected to the vehicle body 1 through the rotating shaft 19, and the swing rod 7 and the cover plate 4 are fixedly connected through the rotating shaft 19.

[0033] There are two sets of the aforementioned link mechanisms, which are respectively arranged at positions close to the ends of both ends of the rotating shaft 19. The push rods 9 of the two link mechanisms respectively act on the positions close to both ends of the lifting box 5, making the lifting process of the lifting box 5 more stable.

[0034] An armrest rod 20 is further provided. The two ends of the armrest rod 20 serve as pin shafts. The swing rod 7 and the connecting rod 8 of a link mechanism are rotatably connected through one end of the armrest rod 20, and the swing rod 7 and the connecting rod 8 of another link mechanism are rotatably connected through the other end of the armrest rod 20. Further, a rubber sleeve is sleeved on the middle part of the armrest rod 20. As Figure 1 shown, in the retracted state of the rescue vehicle, the armrest rod 20 extends away from the vehicle body 1. At this time, it is convenient to hold the armrest rod 20 to push the rescue vehicle; as Figure 6 shown, in the deployed state of the rescue vehicle, the armrest rod 20 abuts against the back plate of the vehicle body 1. At this time, the armrest rod 20 plays a limiting role, and the provided rubber sleeve enables the armrest rod 20 to be in flexible contact with the back plate of the vehicle body 1.

[0035] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields.
