When the stretcher is to be folded, the two third stretcher bars 43 are pushed to expand and contract in the corresponding first stretcher bars 41, and the two third stretcher bars 43 telescopically drives the head height adjustment plate 3 to move, the head height adjustment plate 3 enters the base frame 1 by sliding in the sliding groove 10, the head height adjustment plate 3 is provided with a plurality of second adjustment grooves 15, the second The adjustment grooves 15 are distributed in a vertical equidistant array, and the bottom of the head pad 112 is provided with a third groove 17, and the third groove 17 is rotatably installed with a second bracket 13 that fits against the second adjustment groove 15 for use. When adjusting the inclination angle of the head protection pad 112, the second bracket 13 is rotated out from the third groove 17, and pressed against the second adjustment groove 15. When the inclination angle to be adjusted is large, the second bracket 13 against the second adjustment slot 15 at the end farther from the head pad 112 , otherwise when the adjustment angle is small, the second bracket 13 is against the second adjustment slot 15 near the end of the head pad 112 .

The inner sides corresponding to the two second stretcher bars 42 are provided with a first groove 7, and a support mechanism 8 is rotatably installed in the first groove 7, and the support mechanism 8 includes a telescopic support rod rotatably installed in the first groove 7 81, the length of the telescopic support rod 81 is equal to the distance between the two parallel second stretcher rods 42, the telescopic support rods 81 connected to the two second single frame rods 42 are in a dislocation distribution, and the lower limb pads 113 must be in a horizontal state , the telescopic support rod 81 in the first groove 7 is rotated to the vertical direction, and the telescopic support rod 81 is stretched into the corresponding first groove 7 of the second stretcher rod 42 and fixed. At this time, the two telescopic support rods 81 are parallel to each other and vertically connect the two second stretcher bars 42. At this time, the lower limb protection pad 113 is placed on the two telescopic support bars 81 to complete the horizontal state.

Foldable guardrails 6 are installed on both sides of the underframe 1, and a lock force switch 5 is installed on one end of the foldable guardrail 6. First horizontal tubes 62 are installed on both sides of the underframe 1, and several upper rails are arranged at equal intervals on the first horizontal tubes 62. The card holder 19, the second horizontal tube 61 is correspondingly arranged above the first horizontal tube 62, and several lower card seats 20 are arranged at equal intervals on the second horizontal tube 61, and the upper card holder 19 and the lower card holder 20 are connected by a vertical tube , one end of the vertical tube is clamped in the upper card seat 19, the other end is clamped in the lower card seat 20, the locking force switch 5 is sleeved in one end of the second horizontal tube 61, locked with the vertical tube connecting pin, close to the locking force There is a locking hole on the first vertical tube of the switch 5, and the lock head of the locking force switch 5 is set in the locking hole. When you need to use a stretcher or a folding stretcher, you can press the locking force switch 5 to realize the folding guardrail Fold and open.

Working principle: when the foldable stretcher is in use, the second stretcher bar 42 and the third stretcher bar 43 are telescopically pulled out from the first stretcher bar 41, and the third stretcher bar 43 is pulled out to drive the head height adjustment plate at the same time 3. Slide out from the sliding groove 10. At this time, the stretcher pad mechanism 11 is in the horizontal position. At this time, the telescopic support rod 81 in the first groove 7 is rotated to the vertical direction, and the telescopic support rod 81 is stretched to the corresponding first position. In a groove 7 and fixed, now two telescopic support rods 81 are parallel to each other, and vertically connect two second stretcher rods 42, at this moment, lower limb protection pad 113 is placed on two telescopic support rods 81, lower limb protection pad 113 is in a horizontal state. At this time, the wounded is placed on the stretcher pad mechanism 11. When the wounded does not need to adjust the posture, the second stretcher bar 42 and the third stretcher bar 43 can be lifted to drive the stretcher to transport the wounded. When adjusting the posture, if the position of the head needs to be adjusted, the second bracket 13 in the third groove 17 is rotated out according to the inclination angle required by the wounded person’s condition, and reaches the second adjustment position provided on the head height adjustment plate 3. on the groove 15, and the second adjustment grooves 15 are distributed in a vertical equidistant array, when the angle needs to be adjusted up, it can reach the second adjustment groove 15 on the side closest to the head pad 112, otherwise when the angle is lowered At this time, it can reach the second adjustment groove 15 on the side away from the head protection pad 112. When the lower limbs of the wounded need to be adjusted in height, the lower limb protection pad 113 is pulled up at this time, and the two telescopic support rods 81 are stretched and rotated in a staggered manner. Retract in the first groove 7, rotate the first bracket 12 in the second groove 16, the bottom frame 1 two sides are equipped with the rotation groove 9, the bottom frame 1 both sides are fixedly installed with the third bracket 18, the second The three brackets 18 are provided with a rotation groove 9, and the lower limb height adjustment plate 2 is rotated and installed in the rotation groove 9. a first adjustment slot 14, and the first adjustment slots 14 are distributed in a vertical equidistant array, and the first bracket 12 is pushed against the first adjustment slot 14, so as to adjust the height of the lower limb pad 113, when the angle of inclination is to be adjusted When it is large, put the first bracket 12 against the first adjustment groove 14 at the lower end of the lower limb height adjustment plate 2; on the adjustment groove 14, thereby completing the posture adjustment of the wounded on the stretcher pad mechanism 11, when the wounded is transported successfully, the second support 13 is rotated into the third groove 17, and the head pad 112 is folded on the stretcher pad mechanism 11 through the rubber belt. On the stretcher pad 111, the third stretcher bar 43 is pushed and stretched into the first stretcher bar 41, thereby driving the head height adjustment plate 3 to slide into the sliding groove 10 until it reaches the bottom frame 1, and the lock switch 5 will be opened The foldable guardrail 6 is folded on the base frame 1, the lower limb pad 113 is lifted, the two telescopic support rods 81 are staggered and rotated into the first groove 7, and then the first bracket 12 is rotated into the second groove 16 , the lower limb pad 113 is folded on the stretcher pad 11 through the rubber band 1, push the second stretcher bar 42 to telescopically enter the first stretcher bar 41, and turn the lower limb height adjustment plate 2 to the bottom of the bottom frame 1 through the rotation groove 9, thereby completing the folding of the entire stretcher.
