Example Embodiment

[0025] The technical scheme of the present invention will be further explained below in conjunction with the drawings.

[0026] See Figure 1-3 As shown, the above-mentioned ambulance stretcher includes a bed frame 1, a front wheel 2 arranged at the front end of the bed frame 1, a rear wheel 3 arranged at the bottom of the rear end of the bed frame 1, and at least two extending directions along the length of the bed frame 1. Folding mechanisms arranged at intervals below the bed frame 1. The front here refers to the direction of the head of the bed, and the back refers to the direction of the foot of the bed.

[0027] The above-mentioned folding mechanism includes a first support rod 4 arranged below the bed frame 1 which can be rotated around the first axis through its upper end, a second support rod 5 connected to the lower end of the first support rod 4 by a lower end, and a second support rod 5 that can rotate around the first support rod 4. A first rotating shaft 6 arranged ...

Abstract

The invention discloses an ambulance stretcher. The ambulance stretcher comprises a bedstead, a folding mechanism, a locking mechanism and a driving mechanism, wherein the folding mechanism comprises a first supporting rod which can rotate around a first axis line through the upper end of the first supporting rod, a second supporting rod of which the lower end is hinged to the lower end of the first supporting rod, a first rotating shaft which can rotate around a second axis line and to which a first connecting plate is connected, and a third supporting rod of which the upper end is fixedly connected to the first rotating shaft and the lower end is hinged to the upper end of the second supporting rod; the locking mechanism comprises a locking plate which can rotate around a third axis line and is used for being propped against or away from the first connecting plate; the driving mechanism comprises a second rotating shaft which can rotate around a fourth axis line and to which a second connecting plate for being propped against the first connecting plate to drive the third connecting rod to rotate upwards is connected; the first axis line, the second axis line, the fourth axis line and the third axis line separately extend in the horizontal direction, and the first axis line, the second axis line and the fourth axis line separately extend in the left and right direction of the bedstead and are perpendicular to the third axis line. The ambulance stretcher disclosed by the invention is simple in structure and good in locking effect; and during impact, folding is easier.

Description

technical field [0001] The invention relates to an ambulance stretcher. Background technique [0002] In the existing ambulance stretcher, the locking mechanism for locking the folding legs is generally more complicated. At the same time, the folding legs generally rely on the impact from the front to realize the folding action. When the impact is not strong enough, it is not easy to enter the folded state. Contents of the invention [0003] The purpose of the present invention is to provide an ambulance stretcher, the locking mechanism is only used to lock the frontmost folding mechanism, the structure is simple, and the locking effect is good; the driving mechanism cooperates with the impact to make the folding mechanism easier to fold. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An ambulance stretcher, comprising a bed frame, front wheels and rear wheels arranged at both ends of the bed frame, at le...
