[0002] Medical trolley refers to ward protection and transportation of medical equipment, surgical instruments, medicines and patient transportation. It can greatly reduce the operation burden of nurses. From the classification of products, medical trolleys have luxury, medium and ordinary ones. From the material of the product, medical trolleys have ABS, stainless steel and plastic spraying. From the type of the product, medical trolleys have rescue trolleys, first aid trolleys, treatment trolleys, medical record trolleys, instrument trolleys, instrument trolleys, medicine delivery trolleys, anesthesia trolleys, waste trolleys, infusion trolleys, medicine picking trolleys, lower collection trolleys, upper delivery trolleys and patient transport trolleys and dozens of other types.
[0003] The medical cart is a device used by nurses for infusion, treatment and other operations, and has the function of simply placing treatment instruments and medicines. At present, there are two ways to fix the wheels of the medical cart on the body of the medical cart. One is to fix the wheels on the body of the medical cart by screws, and the other is to fix the wheels on the body of the medical cart by welding. Although the two methods can effectively fix the wheels, under the frequent use of the medical cart and when the load is too heavy, the wheels will be severely damaged, affecting the use of the medical cart, and the wheels on the medical cart need to be replaced. When the wheels are replaced by screw fixing method, the objects on the medical cart need to be cleaned and then turned over for replacement operation, which is relatively inconvenient. The wheels fixed by welding method cannot be replaced, and the whole medical cart needs to be replaced.
[0004] Therefore, the present application provides a medical cart which is simple to operate and convenient to replace wheels. Content of the utility model

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.
[0030] A medical cart that allows for easy replacement of rollers, such as Figure 1 , 2 As shown, the device includes a medical cart body 1 and rollers 2. A locking block 3 is fixed to the upper end of the rollers 2. A locking groove 4 is provided on the lower side wall of the medical cart body 1 to fit into the locking block 3. The locking groove 4 has an inverted U-shaped cross section in the extending direction. The locking groove 4 communicates with the lower surface of the medical cart body 1, and the locking block 3 can only move along the opening direction of the locking groove 4 on the lower side wall of the medical cart body 1. A limiting member is installed on the lower side wall of the medical cart body 1 to fix the locking block 3 in the locking groove 4. A storage groove 5 is provided on the lower surface of the medical cart body 1 and adjacent to the corresponding roller 2. A support member for supporting the medical cart body 1 and for storage is rotatably installed in the storage groove 5.
[0031] like Figure 1 , 3As shown, the lower side wall of the medical vehicle body 1 is provided with a sliding groove 6 that communicates with the snap-fit groove 4. The limiting component includes a limiting block 7 that is slidably installed on the sliding groove 6 and used to press the snap-fit block 3 against the snap-fit groove 4, and a force-applying spring 8 installed in the sliding groove 6 and always applying force to the limiting block 7 to move in the direction of the snap-fit groove 4. One end of the force-applying spring 8 is fixed to the limiting block 7, and the other end is fixed to the end face of the sliding groove 6. The limiting block 7 moves along the extension direction of the sliding groove 6, and the force-applying spring 8 is located between the limiting block 7 and the inner wall of the sliding groove 6.
[0032] When roller 2 needs to be disassembled, a force can be applied to the limiting block 7 in the direction of the force spring 8, so that the limiting block 7 moves along the sliding groove 6 and compresses the force spring 8. After the limiting block 7 separates from the locking block 3, the locking block 3 can be operated. When roller 2 needs to be fixed, after roller 2 is replaced, the limiting block 7 is released, and the force spring 8 applies a force to the limiting block 7 in the direction of the locking block 3. Under the action of the force spring 8, the limiting block 7 moves toward the locking block 3 and finally limits the locking block 3 in the locking groove 4.
[0033] Furthermore, the sliding groove 6 has a convex cross-section, and the limiting block 7 cooperates with the sliding groove 6. The end of the limiting block 7 away from the medical cart body 1 has a frosted finish. The convex cross-section of the sliding groove 6 effectively ensures that the limiting block 7 can only move along the extension direction of the sliding groove 6. The frosted finish of the end of the limiting block 7 away from the medical cart body 1 makes it easier for the operator to apply force to the limiting block 7, increasing friction and preventing slippage.
[0034] like Figure 4 , 5 As shown, the support includes a support rod 9 rotatably mounted in the storage groove 5 at one end, a return spring 10 mounted in the storage groove 5 and applying a force toward the inside of the storage groove 5 to the support rod 9, a pull ring 11 mounted on the end of the support rod 9 away from the return spring 10, and a U-shaped limiting member 12 mounted in the storage groove 5 for limiting the support rod 9. One end of the return spring 10 is fixed to the support rod 9, and the other end is fixed to the bottom surface of the storage groove 5. When the support rod 9 abuts against the U-shaped limiting member, the support rod 9 is in a vertical state, and the corresponding roller 2 is disengaged from the ground. When the medical cart body 1 needs to be supported by the support member, the support rod 9 rotates along its axis by pulling the pull ring 11. During the rotation of the support rod 9, the return spring 10 is stretched. When the support rod 9 supports and presses against the U-shaped limit member 12 and the medical cart body 1 is upright, the support rod 9 is in the set state. When the support member needs to be stored, a force is applied to the support rod 9 in the direction of the return spring 10, and the support rod 9 is stored in the storage groove 5 under the action of the return spring 10, thus completing the storage of the support member.
[0035] Furthermore, the end of the support rod 9 away from its hinge is rounded, which can play a guiding role in the process of the support rod 9 erecting the medical vehicle body 1, making it easier for the support rod 9 to be erected.
[0036] The working process and beneficial effects of this utility model are as follows: When the roller 2 of the medical cart body 1 is damaged, the support member in the storage groove 5 corresponding to the damaged roller 2 can be operated first to support the medical cart body 1. Then, the limiting member is operated to disengage it from the limiting block 7. Next, the snap-fit block 3 along with the roller 2 is taken out from the snap-fit groove 4, thus completing the removal of the roller 2. Then, the new roller 2 is inserted along the snap-fit groove 4. After the snap-fit block 3 and the snap-fit groove 4 cooperate with each other, the limiting member is operated to press against the snap-fit block 3, thus firmly fixing the snap-fit block 3 in the snap-fit groove 4. Finally, the support member is applied to store it, thus completing the replacement of the roller 2.
[0037] In summary, the above-mentioned storage slot 5 and support member can support the medical cart body 1, and the roller 2 can be replaced through the snap-fit block 3, snap-fit slot 4 and limiting member, thereby achieving the purpose of eliminating the need to clean the items on the medical cart, and making the replacement of roller 2 simple and efficient.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
