Detailed Description

The present invention will be described in further non-limiting detail with reference to the following preferred embodiments and accompanying drawings.

As shown in fig. 1, the stretcher support for vehicle according to a preferred embodiment of the present invention includes an underframe 1 connected to the floor of the compartment, a sliding assembly 2 slidably coupled to the underframe 1, and a stretcher loading platform 3 connected to the sliding assembly 2.

With further reference to fig. 2, the chassis 1 is provided with a first sliding groove 10 and a second sliding groove 11 on both sides, and the second sliding groove 11 and the first sliding groove 10 are arranged at an interval from top to bottom and are parallel to each other. The lower end of the underframe 1 is connected with a pillar 12, the bottom of the pillar 12 is connected to the bottom plate of the carriage through a vibration isolator 13, and the stretcher fixed on the stretcher support for the vehicle can be more stable by means of the damping effect of the vibration isolator 13.

The sliding assemblies 2 are two groups, which are respectively connected to two sides of the base frame 1, and each sliding assembly comprises a support member 20, a first roller 21 and a second roller 22 connected to the support member 20, a sliding rail assembly 23 connected to the support member 20, and a connecting member 24 connected between the sliding rail assembly 23 and the stretcher loading platform 3. The support members 20 of the two sets of glide assemblies 2 may be connected by connecting rods 26 or the like to increase overall structural strength and rigidity.

The support member 20 is in an L-shaped plate shape, and includes a vertical plate portion 200 disposed vertically and a flat plate portion 201 disposed horizontally. The first roller 21 and the second roller 22 are connected to the riser 200 via the shafts 25 and are capable of rotating around their respective axes. The first roller 21 and the second roller 22 are respectively fitted in the first runner 10 and the second runner 11 so that the sliding assembly 2 can slide along the first runner 10 and the second runner 11.

The slide rail assembly 23 includes a slide rail 230 connected to the vertical plate portion 200 and a slider 231 slidably coupled to the slide rail 230. The connecting element 24 is connected between the stretcher loading platform 3 and the slide 231 and can slide along the slide rails 230.

The stretcher loading platform 3 is used for fixing a stretcher, and the locking and positioning device 30 for fixing a stretcher is provided on the stretcher loading platform 3, which is a prior art, for example, refer to the locking and positioning device of the patent technology mentioned in the background section, and will not be described in detail herein.

The first rollers 21 are more numerous (both two are included) so that in normal conditions, both the stretcher loading platform 3 and the sliding module 2 can only slide horizontally along the chute and cannot tilt. In order to enable the tilting of the stretcher loading platform 3 and the glide assembly 2, as shown in fig. 3 to 5, a notch 110 is provided above the second chute 11, the notch 110 being larger than the diameter of the second roller 22 so that the second roller 22 can be removed from the notch 110. When the stretcher loading platform 3 is pulled, the number of the first and second rollers 21 and 22 fitted into the first and second chutes 10 and 11 becomes smaller and smaller because the first and second rollers 21 and 22 are successively drawn out of the first and second chutes 10 and 11. When only one first roller 21 (i.e., the roller indicated by the reference numeral 21a in fig. 3) and one second roller 22 (i.e., the roller indicated by the reference numeral 22a in fig. 3) are still engaged with the chute, the stretcher loading platform 3 is adjusted until the second roller 22 is aligned with the notch 110, and the suspended end of the stretcher loading platform 3 can be tilted downward because the second roller 22 can be moved out of the notch 110 after tilting without being blocked.

After the stretcher loading platform 3 is inclined downwards, the height above the ground can be shortened, so that the stretcher can be conveniently mounted and dismounted, and the stretcher can be conveniently pushed onto the underframe 1.

Two chutes (a first chute 10 and a second chute 11) are provided, so that the stretcher loading platform 3 can be conveniently aligned to be horizontal after being lifted: when the end of the inclined litter loading platform 3 is lifted, the second roller 22 is rotated to be supported by the bottom surface of the second chute 11, which indicates that the litter loading platform 3 is already in the substantially horizontal position, and then only a horizontal force is applied to push the litter loading platform 3 into the base frame 1.

As shown in fig. 4 and 5, a tilting assistance device 4 is further connected between the skid assembly 2 and the chassis 1, and the tilting assistance device 4 includes a connecting wheel 40 coupled in the first sliding chute 10, a first rotating shaft 41 connected to the connecting wheel 40, a link 42 connected to the first rotating shaft 41, a second rotating shaft 44 connected to the vertical plate portion 200, and a first air spring 43 connected between the first rotating shaft 41 and the second rotating shaft 44.
