Silent base of wheel stretcher

Abstract

The wheel stretcher mute base comprises a bottom frame, brake wheels are installed on the periphery of the bottom frame, straight wheels are installed in the middle of the bottom frame, and a brake linkage mechanism for driving the four brake wheels to be locked at the same time and a straight guide mechanism for adjusting the straight wheels to be lifted are installed on the bottom frame. The straight guide mechanism comprises a first mounting plate fixedly connected with the bottom frame. The pedal pipe drives the cam sleeve to drive the locking cam to rotate anticlockwise, the first clamping groove is relatively separated from the fixing pin and enters the second clamping groove, meanwhile, the spring restores to the original state, the second mounting plate is driven to rotate anticlockwise around the mounting column, the step face of the step-shaped clamping groove of the fixing pin abuts against, and the straight moving wheel is put down to make contact with the ground. In the process of moving the wheel stretcher, due to the guiding effect of the straight wheels, the wheel stretcher stably moves in one direction, the problem that the moving direction is not stable due to universal wheels is solved, and smooth proceeding of first-aid work is facilitated.

Description

technical field [0001] The invention relates to the technical field of stretcher vehicles, in particular to a silent base of the stretcher vehicle. Background technique [0002] Transporting patients is a job that requires high speed and efficiency. A stretcher trolley is a very common medical equipment in the emergency process. The stretcher trolley is used to transfer the patient to the ambulance. The existing stretcher trolley is installed around the bottom. There are swivel wheels with brakes to facilitate the movement and steering of the stretcher cart. [0003] However, firstly, due to the existence of the universal wheel, the direction of the stretcher car is unstable when it is moving, and it is difficult to control the stretcher car to move stably in one direction, which affects the emergency work. Each swivel wheel exists as an independent brake, that is, when the stretcher car needs to be positioned, it is more troublesome to step on the brake pads of the four sw...

Problems solved by technology

[0003] However, first of all, due to the existence of universal wheels, there is a problem of unstable direction when the stretcher is moving, and it is difficult to control the stretcher to move stably in one direction, which affects the emergency work. There are four universal wheels with independent brakes, that is, when the stretcher needs to be positioned, it is necessary to step on the brake pads one by one to brake the four universal wheels, which is troublesome.
