Abstract

The utility model discloses a wheel stretcher for an ambulance, which comprises two back support legs, wherein the lower ends of the two back support legs are respectively provided with a universal wheel; each universal wheel comprise a plurality of fixed discs, a caster support and a caster; and each caster support is connected with the four fixed discs by a plurality of bearings, the axial lead of each bearing is vertically penetrated through the center of each fixed disc, and each caster is arranged on each caster support. The top of each caster support is provided with a magnet, the corresponding position of each fixed disc is provided with an iron sheet correspondingly, and each iron sheet is outwards extended along the edge of each fixed disc; and each fixed disc is fixed at the lower end of each back support leg, and each iron sheet is arranged right behind each back support leg. As each universal wheel is provided with a magnetic locating mechanism, the situation that the assembly process of the ambulance is invariable since the position of each universal wheel is variable can be avoided when the wheel stretcher is folded.

Description

The ambulance stretcher

Technical field

This utility model relates to a kind of stretcher, is a kind of ambulance stretcher specifically.

Background technology

Existing ambulance stretcher, its castor adopts universal wheel or directional wheel more.1. the universal wheel (see figure 1) can make ambulance stretcher mobile more convenient on the level land, but in the folding process on stretcher during ambulance, the location status of the universal wheel of two rear support leg because of can't be maintained fixed always, action and the direction of getting on the bus is difficult to control, make folding can't carrying out more smoothly, therefore, need the position by free-hand adjusting universal wheel, the complexity that makes the ambulance stretcher car process of getting on the bus become is like this required great effort.Though the 2. directional wheel position that can be maintained fixed in the folding process of last ambulance, carrying out on the level land can't travel direction control when mobile.

The utility model content

Technical problem to be solved in the utility model is to overcome the above-mentioned defective that prior art exists, and has proposed a kind of ambulance stretcher, and the universal wheel of two rear support leg has the magnetic force detent mechanism, and the Convenient stretcher car is got on the bus.

This utility model ambulance stretcher comprises two rear support legs, and two rear support leg lower ends are equipped with universal wheel.

Described universal wheel comprises fixed disc, trundle bracket and foot wheel; Be connected by bearing between trundle bracket and the fixed disc, the axial line of bearing vertically passes the fixed disc center of circle, and castor is installed on the trundle bracket; It is characterized in that: be provided with Magnet at the trundle bracket top, corresponding with it, be provided with iron plate in the fixed disc relevant position, described iron plate is protruding along the edge of fixed disc; As the replacement of equivalent technologies means, described Magnet also can be arranged on the described iron plate, and its effect is identical; Described fixed disc is fixed on the rear support leg bottom, and described iron plate is positioned at the dead astern (direction of advance with stretcher is preceding) of rear support leg.

This utility model ambulance stretcher, when last ambulance, ambulance uses stretcher with the past ambulance carriage movements of rectilinear direction, in the process of motion, the power that universal wheel is subjected to pushing away forward, the automatic back track of the castor of universal wheel, on this position, iron plate and Magnet keep minimum distance, this moment, captivation between the two reached maximum, the front leg strut of ambulance stretcher and rear support leg are folding successively, and universal wheel is subjected to the captivation between iron plate and Magnet in a folding process, keeps this location status always.In folding process, what universal wheel can be because of its position is indefinite, causes the constant of ambulance process.

When stretcher need turn to, only need to give stretcher one side force, iron plate and Magnet can be separated, realize that stretcher turns to.

The specific embodiment

Below in conjunction with drawings and Examples, this utility model is elaborated.

Shown in Fig. 2,4, this utility model ambulance stretcher includes 4, two rear support leg lower ends of two rear support legs and is equipped with universal wheel.

Described universal wheel comprises fixed disc 6, trundle bracket 5 and castor 7; Be connected by bearing between trundle bracket and the fixed disc, the axial line of bearing vertically passes the fixed disc center of circle, and castor is installed on the trundle bracket.In magnet holder 3 of trundle bracket welded top, Magnet 2 is fixed on the magnet holder, and is corresponding with it, is provided with iron plate 1 in the fixed disc relevant position, and described iron plate is protruding along the edge of fixed disc; As the replacement of equivalent technologies means, described Magnet also can be arranged on the described iron plate, and its effect is identical; Described fixed disc is fixed on the rear support leg bottom, and described iron plate is positioned at the dead astern of rear support leg.

This ambulance stretcher, when shifting on the level land, medical personnel only need slightly firmly can change the direction of stretcher; When last ambulance, stretcher is with the past ambulance carriage movements of rectilinear direction, in the process of motion, the power that universal wheel is subjected to pushing away forward, the automatic back track of the castor of universal wheel, on this position, iron plate 1 keeps minimum distance with Magnet 2, and this moment, captivation between the two reached maximum, and the front leg strut of ambulance stretcher and rear support leg are folding successively, universal wheel is subjected to the captivation between iron plate and Magnet in a folding process, keeps this location status always.In folding process, what universal wheel can be because of its position is indefinite, causes the constant of ambulance process.
