Abstract

A medical vehicle walking guide device pertains to the technical field of medical devices. The technical problem needs to be solved is to provide the guide device which can drive the medical vehicle bed which is provided with an universal foot wheel to walk in the pushing direction of the people, so as to avoid the unnecessary left and right swing phenomenon. The composition includes a guide wheel, a wheel shaft and a support arm which is connected with the wheel shaft, the support arm is fixed with a rocker shaft, a rocker arm which is provided with a limit groove and is fixed on the rocker shaft is connected with a spring, and a limit block which is opposite to the limit groove of the rocker arm is fixed on a control shaft. The medical vehicle bed which is provided with the universal foot wheel of the utility model can go forward along the pushing direction of the people during the walking, which can effectively prevent the unnecessary left and right swing of the medical vehicle bed during the walking. When in need of the horizontal displacement of the medical vehicle bed, a control rod pedal can be pedaled, the guide wheel can be raised to detach from the contact with the ground, so the horizontal displacement can be achieved freely. The utility model is suitable to be fixed on the medical vehicle bed frame which is provided with the universal foot wheel for use.

Description

Vehicle for medical use (bed) walking guider

Technical field

This utility model relates to the walking guider of a kind of vehicle for medical use (bed), belongs to technical field of medical instruments.

Background technology

At present, the vehicle for medical use (bed) of the band universal caster wheel that hospital is commonly used particularly has not at ordinary times when the road surface when walking slightly, and its universal caster wheel often makes the implementation direction be difficult to accurate control, and it is very inconvenient that user is felt.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of vehicle for medical use (bed) walking guider, and this device can make the vehicle for medical use (bed) of band universal caster wheel when walking, advances by people's thrust direction, overcomes the unnecessary phenomenon that swings.

The technical solution of the utility model is: a kind of vehicle for medical use (bed) walking guider, it comprises directive wheel, wheel shaft and the support arm that links to each other with wheel shaft, said support arm with wave the axle fixedly connected, be fixed in the swing arm that is provided with stopper slot of waving on the axle and link to each other with spring, the limited block relative with the stopper slot of swing arm is fixed on the Control Shaft.

Above-mentioned vehicle for medical use (bed) walking guider, the described axle that waves is loaded on the bearing, bearing is fixed on the connecting plate, said both ends of the spring is equipped with spring base, one of them spring base and swing arm are hinged, and another spring base and linking arm are hinged, and linking arm is fixed on the connecting plate, said Control Shaft is contained on the connecting plate, and connecting plate is fixed on vehicle for medical use (bed) frame of band universal caster wheel.

Above-mentioned vehicle for medical use (bed) walking guider, described Control Shaft one end is fixed with the control stick of band pedal.

Above-mentioned vehicle for medical use (bed) walking guider, described Control Shaft is provided with the damping support arm, and the damping support arm links to each other with an end of damping spring, and the other end of damping spring links to each other with linking arm on being fixed in connecting plate.

Above-mentioned vehicle for medical use (bed) walking guider, roller is equipped with in the end of described limited block, to reduce the friction of contact surface between limited block and swing arm.

Vehicle for medical use provided by the utility model (bed) walking guider is contained on vehicle for medical use (bed) frame of band universal caster wheel, when walking, can advance by people's thrust direction, can prevent vehicle for medical use (bed) unnecessary the swinging when driving into of being expert at effectively.In addition, when needs vehicle for medical use (bed) lateral displacement, can step the control stick pedal, limited block is withstood in the stopper slot of swing arm, like this, directive wheel can be raised, and disengaging contacts with ground, and lateral displacement just can arbitrarily be realized.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:

Referring to Fig. 1, this vehicle for medical use (bed) walking guider comprises directive wheel 5, wheel shaft 4 and the support arm 3 that links to each other with wheel shaft, and connecting plate 2 of the present utility model is fixing with the vehicle frame 1 of band universal caster wheel 6.

Referring to Fig. 2-Fig. 5, the wheel shaft 4 of present embodiment directive wheel 5 links to each other with support arm 3, support arm 3 is with to wave axle 7 fixing, waving axle 7 is loaded on the bearing 8, bearing 8 is fixed on the connecting plate 2, it is hinged with a spring base 13 of spring 12 to be fixed in the swing arm that is provided with stopper slot 23 14 of waving on the axle 7, another spring base 11 of spring 12 is hinged with linking arm 10, linking arm 10 is fixed on the connecting plate 2, the limited block 21 that roller 20 is equipped with in the end relative with the stopper slot 23 of swing arm 14 is fixed on the Control Shaft 17, Control Shaft 17 is contained on the connecting plate 2, and Control Shaft 17 1 ends are fixed with

band pedal

9,16 control stick 15.When the vehicle for medical use (bed) of band universal caster wheel needs guiding to advance, treadle 16, make limited block 21 break away from spacing state, at this moment, swing arm 14 drives under the effect of spring 12 power waves axle 7 rotations, waves axle 7 and drives support arm 3 and directive wheel 5 rotations again, and directive wheel 5 is contacted with ground.Can overcome the omnidirectional phenomenon of advancing of vehicle for medical use (bed) of band universal caster wheel like this.

When vehicle for medical use (bed) does not need to lead when mobile, during as lateral displacement, treadle 9, make limited block 21 promote swing arm 14 compression springs 12, and the roller 20 on the limited block 21 is snapped in the stopper slot 23 of swing arm 14, simultaneously, directive wheel 5 is at support arm 3 and wave under the drive of axle 7 and rise, and breaks away from and the contacting of ground.
