Description

Technical Field

[0001] This application relates to the technical field of medicine delivery tools, and in particular to a medicine delivery vehicle. Background Technology

[0002] The pharmacy department is an important department in the hospital responsible for drug management, dispensing, formulation research and development, and providing pharmaceutical services. It plays a key role in ensuring the smooth operation of the hospital's medical work and the rational use of drugs by patients. It undertakes the important responsibility of providing accurate and timely drug supply to all departments of the hospital. In the process of drug delivery, drug delivery vehicles are usually used. As a key tool for drug transportation, the performance of the drug delivery vehicle directly affects the efficiency and quality of drug delivery.

[0003] As hospitals continue to expand and the number of patients increases, the pharmacy department faces increasingly heavy tasks in dispensing and transporting medicines. To meet the timely needs of various departments for medicines, delivery vehicles need to be able to maneuver flexibly in the complex environment of the hospital and deliver various medicines to designated locations accurately. Therefore, to facilitate the free movement of delivery vehicles in hospital corridors, elevators, and between departments, most delivery vehicles are equipped with casters at the bottom. The application of casters has indeed greatly improved the mobility of delivery vehicles, enabling them to quickly respond to the medicine needs of different departments and efficiently complete the medicine transportation work within the hospital.

[0004] However, in actual use, when the medicine delivery cart stops moving so that staff can retrieve the medicine, the casters are prone to slipping, causing the cart to move. This not only causes great inconvenience to staff in retrieving the medicine, but may also cause the medicine placed on the cart to tip over or be damaged due to the shaking of the cart, affecting the normal supply of medicine. Some medicine delivery carts use self-locking casters. Although this design can fix the cart to a certain extent, the existing casters generally have a line-surface contact with the ground, with a small contact area. When subjected to external impact, they are prone to slipping, resulting in insufficient stability. Therefore, we have proposed a medicine delivery cart. Utility Model Content

[0005] In order to improve the problem that existing omnidirectional wheels generally have a line-to-surface contact with the ground, resulting in a small contact area and easy slippage when subjected to external force, leading to insufficient stability, this application provides a medicine delivery vehicle.

[0006] The medicine delivery vehicle provided in this application adopts the following technical solution:

[0007] A medicine delivery cart includes a cabinet. A base plate is fixedly connected to the lower surface of the cabinet, and a top plate is fixedly connected to the upper surface of the cabinet. A fixing cylinder is provided on the front of the cabinet, with its upper end fixedly connected to the top plate and its lower end fixedly connected to the base plate. A sliding rod is provided inside the fixing cylinder, and a fixing mechanism is provided at the lower end of the sliding rod for surface contact with the ground to prevent the cabinet from sliding. A storage mechanism is provided inside the cabinet, and a locking mechanism is provided on the outer surface of the sliding rod to block the storage mechanism and prevent it from sliding outward. A limit mechanism is provided on the upper surface of the top plate to limit the position of the sliding rod.

[0008] By adopting the above solution, when transporting medicines to a designated location or when medicines need to be removed, first lift the sliding rod upwards to disengage the upper end of the sliding rod from the limiting mechanism. Then rotate the sliding rod 90 degrees so that it can move downwards. At the same time, the sliding rod will drive the fixing mechanism downwards, so that the fixing mechanism contacts the ground. The fixing mechanism supports the overall weight and achieves surface-to-surface contact to prevent the cabinet from sliding. This eliminates the need for squatting, making it convenient to use and achieving the effect of easy operation. This solves the problem that existing self-locking caster wheels usually have locking devices located close to the ground, requiring staff to squat down to operate the locking device every time they stop to retrieve medicines, which is quite troublesome.

[0009] Furthermore, a guardrail is fixedly connected to the upper surface of the top plate, and casters are fixedly connected to the lower surface of the bottom plate.

[0010] By adopting the above solution, the guardrail is used to block and protect items on the top of the ceiling, and the casters are used to facilitate movement.

[0011] Furthermore, a push plate is fixedly installed on one side of the cabinet, and a trash can is installed on the other side of the cabinet.

[0012] By adopting the above solution, the entire structure can be moved by pushing the plate, and the trash can is used to hold temporary trash.

[0013] Furthermore, the fixing mechanism includes a connecting rod, the upper surface of which is fixedly connected to a sliding rod, a pressing plate rotatably connected to the lower surface of the connecting rod, a slot being provided at the bottom of the fixing cylinder, a locking block being fixedly connected to the outer surface of the connecting rod, the outer surface of the locking block being slidably connected to the slot, and a spring being fixedly connected to the lower surface of the base plate, the lower end of which is fixedly connected to the pressing plate.

[0014] By adopting the above solution, the lower surface of the extrusion plate is provided with a structure to increase the friction surface. When used on rough surfaces that are not afraid of scratches, such as cement floors, spikes can be used. When the surface is smooth, such as stone floors, wear-resistant rubber pads can be used. When it is necessary to fix the vehicle body, the spring gives the extrusion plate a downward elastic force, so that the lower surface of the extrusion plate is pressed into contact with the ground, which can increase the friction of the rest of the ground, thereby increasing the overall stability and preventing the cabinet from sliding due to collision. When not in use, the sliding rod drives the connecting rod to move upward, while compressing the spring, so that the locking block enters the interior of the fixing cylinder from the slot, and then rotates, so that the locking block is locked inside the fixing cylinder, preventing it from moving downward, so as to facilitate the movement of the vehicle body.

[0015] Furthermore, the limiting mechanism includes a limiting plate, the lower surface of which is fixedly connected to the top plate, and the inner wall of the limiting plate is provided with a slot, the inner wall of which is slidably connected to the sliding rod.

[0016] By adopting the above scheme, the limiting plate is L-shaped, and the two slots on it are at different heights. The limiting plate is used to limit the sliding rod so that the sliding rod can rotate accurately. At the same time, the slot with the smaller height is also used for auxiliary support. After the sliding rod moves downward, the bottom of the slot with the larger height does not contact the sliding rod, so that the lower surface of the extrusion plate can be fully stressed by the ground.

[0017] Furthermore, the storage mechanism includes multiple partitions that are fixedly connected to the inner wall of the cabinet, and the interior of the cabinet is provided with multiple drawers that can slide out.

[0018] By adopting the above solution, the partition divides the middle of the cabinet into multiple sections to facilitate the placement of multiple drawers, thereby separating the medicines. The height of each drawer can be customized according to actual needs to form drawers of different heights, making it convenient to place medicines of different sizes.

[0019] Furthermore, the locking mechanism includes a slide groove formed on the side wall of the fixed cylinder, and a stop block is fixedly connected to the outer surface of the sliding rod, with the outer surface of the stop block slidably connected to the slide groove.

[0020] By adopting the above solution, the sliding rod can rotate to drive the stop block to rotate during the rotation process. When the sliding rod drives the fixing mechanism to fix the whole, the stop block is perpendicular to the drawer and does not affect the drawer's outward sliding. When the vehicle needs to move, the sliding rod will drive the stop block to block the front of the drawer to prevent the drawer from opening. Compared with the existing individual locking of each drawer, this device is more convenient and simplifies the unlocking process. It locks when moving and unlocks when taking medicine, making it easy to use.

[0021] In summary, the beneficial technical effects of this application are as follows:

[0022] 1. By setting up components such as sliding rods, when transporting medicines to a designated location or when medicines need to be removed, the sliding rod is first lifted upwards to disengage the upper end of the sliding rod from the limiting mechanism. Then, the sliding rod is rotated 90 degrees, allowing it to move downwards. At the same time, the sliding rod drives the fixing mechanism downwards, making the fixing mechanism in surface contact with the ground. The fixing mechanism supports the overall weight, thereby increasing the contact area with the ground to prevent the cabinet from sliding and increasing stability. This solves the problem that existing universal wheels generally have a line-surface contact with the ground, resulting in a small contact area and easy slippage when subjected to external impact, leading to insufficient stability.

[0023] 2. By setting up components such as a locking mechanism, the sliding rod will rotate, which will drive the locking mechanism to rotate as well. This will prevent the locking mechanism from blocking the storage mechanism, allowing the storage mechanism to be opened. When movement is required, the locking mechanism will block and fix the storage mechanism, preventing it from sliding outward and the medicines on the top plate from falling, thereby increasing the safety of the medicines.

[0032] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] This application discloses a medicine delivery vehicle, as shown in the embodiments below. Figure 1-6 The device includes a cabinet 1, with a base plate 2 fixedly connected to the lower surface of the cabinet 1 and a top plate 3 fixedly connected to the upper surface of the cabinet 1. A fixing cylinder 4 is provided on the front of the cabinet 1, with its upper end fixedly connected to the top plate 3 and its lower end fixedly connected to the base plate 2. A sliding rod 5 is provided inside the fixing cylinder 4, and a fixing mechanism 6 is provided at the lower end of the sliding rod 5. This fixing mechanism 6 is used to make surface contact with the ground to prevent the cabinet 1 from sliding. A storage mechanism 9 is provided inside the cabinet 1, and a locking mechanism 7 is provided on the outer surface of the sliding rod 5 to block the storage mechanism 9 and prevent it from sliding outwards. A limit mechanism 8 is provided on the upper surface of the top plate 3 to limit the position of the sliding rod 5. The sliding rod 5 is L-shaped. The interior of the storage mechanism 9 and the upper part of the top plate 3 are used to store medicines. In use, pushing the cabinet 1 as a whole moves the medicines on it, thereby realizing the transportation of medicines. When the medicines are transported to a designated location or need to be removed, the sliding rod 5 is first lifted upwards. The upper end of the sliding rod 5 is disengaged from the limiting mechanism 8, and then the sliding rod 5 is rotated 90 degrees, allowing it to move downwards. Simultaneously, the sliding rod 5 drives the fixing mechanism 6 downwards, bringing it into contact with the ground. The fixing mechanism 6 replaces the caster wheel 11 to support the overall weight, preventing the cabinet 1 from sliding. This eliminates the need for crouching, making it easier to use. During the rotation of the sliding rod 5, the locking mechanism 7 rotates, removing it from obstructing the storage mechanism 9, allowing it to open. The upper end of the sliding rod 5 also opens, facilitating the removal or placement of medicines from the top plate 3. When movement is required, the upper part of the sliding rod 5 is operated to reset, causing the fixing mechanism 6 to move upwards, applying force to the caster wheel 11 to reduce friction with the ground and facilitate movement. Simultaneously, the upper end of the sliding rod 5 blocks the front of the protective railing 10, and the locking mechanism 7 secures the storage mechanism 9, preventing it from sliding out of the cabinet and the medicines from falling from the top plate 3.

[0034] A guardrail 10 is fixedly connected to the upper surface of the top plate 3, and a caster wheel 11 is fixedly connected to the lower surface of the bottom plate 2. The guardrail 10 is used to block and protect items on the top plate 3, and the caster wheel 11 is used to facilitate movement.

[0035] A push plate 12 is fixedly installed on one side of the cabinet 1, and a trash can 13 is installed on the other side of the cabinet 1. The whole unit can be moved by pushing the push plate 12. The trash can 13 is used to place temporary trash.

[0036] The fixing mechanism 6 includes a connecting rod 601, the upper surface of which is fixedly connected to the sliding rod 5, and a pressing plate 602 rotatably connected to the lower surface of the connecting rod 601. A slot 603 is provided at the bottom of the fixing cylinder 4. A locking block 604 is fixedly connected to the outer surface of the connecting rod 601, and the outer surface of the locking block 604 is slidably connected to the slot 603. A spring 605 is fixedly connected to the lower surface of the base plate 2, and the lower end of the spring 605 is fixedly connected to the pressing plate 602. The lower surface of the pressing plate 602 is provided with a structure to increase the friction surface. When used on rough surfaces that are not susceptible to scratches, such as cement or soil surfaces, a hard plate with spikes can be used. When using materials such as smooth stone floors, wear-resistant rubber pads can be used to increase friction. When it is necessary to fix the vehicle body, the spring 605 applies a downward elastic force to the extrusion plate 602, so that the lower surface of the extrusion plate 602 is pressed into contact with the ground, which can increase the friction of the rest of the ground, thereby increasing the overall stability and preventing the cabinet 1 from sliding due to collision. When not in use, the sliding rod 5 drives the connecting rod 601 to move upward, while compressing the spring 605, so that the locking block 604 enters the interior of the fixing cylinder 4 from the slot 603, and then rotates 90 degrees, so that the locking block 604 is locked inside the fixing cylinder 4, preventing it from moving downward, so as to facilitate the movement of the vehicle body.

[0037] The limiting mechanism 8 includes a limiting plate 801. The lower surface of the limiting plate 801 is fixedly connected to the top plate 3. The inner wall of the limiting plate 801 is provided with a slot 802. The inner wall of the slot 802 is slidably connected to the sliding rod 5. The limiting plate 801 is L-shaped, and the two slots 802 on it are at different heights. The limiting plate 801 is used to limit the sliding rod 5 so that the sliding rod 5 can rotate precisely 90 degrees when it rotates. At the same time, the slot 802 with the smaller height is also used for auxiliary support. After the sliding rod 5 moves downward, the bottom of the slot 802 with the larger height does not contact the sliding rod 5, so that the lower surface of the pressing plate 602 can fully bear the force with the ground.

[0038] The storage mechanism 9 includes multiple partitions 901, which are fixedly connected to the inner wall of the cabinet 1. The cabinet 1 has multiple drawers 902 that can slide out. The partitions 901 divide the middle of the cabinet 1 into multiple sections to facilitate the placement of multiple drawers 902, thereby separating the medicines. The height of each drawer 902 can be customized according to actual needs to form drawers 902 of different heights, which is convenient for placing medicines of different sizes.

[0039] The locking mechanism 7 includes a slide groove 701, which is formed on the side wall of the fixed cylinder 4. A stop block 702 is fixedly connected to the outer surface of the sliding rod 5. The outer surface of the stop block 702 is slidably connected to the slide groove 701. During the rotation of the sliding rod 5, the stop block 702 can be rotated. When the sliding rod 5 drives the fixing mechanism 6 to fix the whole, the stop block 702 is perpendicular to the drawer 902 and does not affect the outward sliding of the drawer 902. When the vehicle needs to move, the sliding rod 5 will drive the stop block 702 to block the front of the drawer 902, preventing the drawer 902 from opening. Compared with the existing individual locking of each drawer 902, this device is more convenient and simplifies the unlocking process. It locks when moving and unlocks when taking medicine, making it easy to use.

[0040] The implementation principle of a medicine delivery vehicle in this application embodiment is as follows:

[0041] The medicine delivery cart mainly relies on the casters 11 fixedly connected to the lower surface of the base plate 2 to move as a whole. By pushing the push plate 12 fixedly installed on one side of the cabinet 1, the staff can easily push the medicine delivery cart to shuttle through the hospital environment and transport the medicines stored in the internal storage mechanism 9 of the cabinet 1 and the upper part of the top plate 3 to the designated location.

[0042] When the medicine delivery vehicle arrives at its destination and needs to be secured, the staff first lifts the sliding rod 5 upwards, causing the upper end of the sliding rod 5 to disengage from the inner wall groove 802 of the limiting plate 801 in the limiting mechanism 8. After disengaging from the limiting, it can be rotated 90 degrees. At this time, the sliding rod 5 can move downwards within the fixed cylinder 4, simultaneously driving the fixed mechanism 6 connected to its lower end to move downwards. The connecting rod 601 of the fixed mechanism 6 descends along with the sliding rod 5, and the locking block 604 slides down along the slot 603 opened at the bottom of the fixed cylinder 4. The spring 605 gives the extrusion plate 602 a downward elastic force, causing the lower surface of the extrusion plate 602 to contact the ground, forming a surface-to-surface contact, thereby increasing the friction with the ground. This replaces the universal wheel 11 in supporting the overall weight of the medicine delivery vehicle, preventing the cabinet 1 from sliding and increasing stability.

[0043] During the rotation of the sliding rod 5, the stop 702 in the locking mechanism 7 fixed on its outer surface also rotates. When the sliding rod 5 drives the fixing mechanism 6 to complete the fixing of the vehicle body, the stop 702 is perpendicular to the drawer 902. At this time, it does not affect the outward sliding of the drawer 902 in the storage mechanism 9, and the staff can open the drawer 902 smoothly to take out or put in medicines.

[0044] When the medicine delivery cart needs to be moved again, the operator operates the sliding rod 5 on the top plate 3 to move it upward. The sliding rod 5 drives the connecting rod 601 to rise, compressing the spring 605. The locking block 604 enters the fixed cylinder 4 from the slot 603 and then rotates 90 degrees, so that the locking block 604 is locked inside the fixed cylinder 4, restricting the downward movement of the fixing mechanism 6. At this time, the caster wheel 11 is stressed again, reducing the friction between the medicine delivery cart and the ground, making it easier to push the medicine delivery cart to move again.

[0045] During the reset process of the sliding rod 5, the stop block 702 rotates with the sliding rod 5 and stops the front of the drawer 902 again to prevent the drawer 902 from opening accidentally during movement. The guardrail 10 fixedly connected to the upper surface of the top plate 3 can prevent the medicines on the top plate 3 from falling off.
