Brake mechanism of medical flat plate trolley

Abstract

The invention discloses a brake mechanism of a medical flat trolley, which comprises a trolley chassis, universal wheels and a brake mechanism. On the wheel, the brake mechanism includes a casing, the rear surface of the casing is provided with a U-shaped movable groove, the middle of the top of the casing is provided with a lever shaft, and a Z-shaped wheel pedal is fixed on the lever shaft, and a limit block is installed inside the left side of the casing to limit the There is a guide rail running through the bit block horizontally, and a hinge ball is installed in the middle of the guide rail. One end of the wheel pedal is connected longitudinally to the hinge ball through a ball hinge. The hinge ball is fixedly connected with a friction block horizontally. Axle telescopic rod transversely passes through movable slot and is connected with a square tread ring, and the middle of connecting telescopic rod is connected with boom frame through movable shaft, and the top of boom frame is fixed on the bottom of cart underframe.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a brake mechanism of a medical flat trolley. Background technique [0002] Medical trolleys refer to the protective transport of medical equipment, surgical instruments, medicines, and patients transported in wards.

Problems solved by technology

It can greatly reduce the burden on caregivers; in terms of product classification, medical carts are luxurious, medium and ordinary; in terms of product materials, medical carts include ABS, stainless steel, Plastic sprayed; according to the type of products, medical carts include rescue carts, ambulance carts, treatment carts, medical records carts, equipment carts, instrument carts, medicine delivery carts, anesthesia carts, sewage carts, infusion carts, and drug collection carts There are dozens of types, such as lower receiving carts, upper delivery carts, and patient transport carts. Due to the large loads of medical carts, the weight of the cart itself is relatively heavy, and it is easy to slip sideways on the relatively smooth ground of the hospital. Most of the trolleys are equipped with wheel braking mechanisms, but most of the trolleys use a wheel-on-a-brake mechanism, so that in an emergency, the faster trolley speed makes it too late for the medical staff to perform simultaneous operations on the two wheels. The brakes make the compass rotate under inertia, which is easy to cause damage to people and objects. One wheel and one brake make each independent universal wheel have an uncertain direction during the rotation process, making it difficult to control the forward route of the cart , especially at faster speeds
