Specifically, a plurality of lock holes 1311 are symmetrically formed in two sides of the lower supporting tube 131 along the height direction of the lower supporting tube, lock tongue holes 1321 are formed in two sides of the bottom of the upper supporting tube 132, and the lock tongue 141, the lock holes 1311 and the lock tongue holes 1321 can be inserted into each other, so that the upper supporting tube 132 and the lower supporting tube 131 are limited in movement and can be positioned and supported through the support of the lock tongue 141. Tongue groove 1411 with the grafting of unblock block 142 both ends is seted up in the top surface middle part of spring bolt 141, avoids spring bolt 141 to slide out two intraductally, and the interior angle of unblock block 142 both ends is the oblique angle structure, and the horizontal width of the interior oblique angle of unblock block 142 and the width of tongue groove 1411 are greater than the wall thickness of lower stay pipe 131 to lift unblock block 142 and utilize its interior oblique angle to insert tongue groove 1411 gradually and promote a pair of spring bolt 141 and draw close, and then break away from lockhole 1311 on the lower stay pipe 131, alright flexible upper stay pipe 132. The middle part of the unlocking block 142 is provided with a pressing block 1421 clamped with the bottom end of the unlocking rod 143, so that the downward-moving unlocking block 142 is clamped between the pair of locking tongues 141 by using the pressing block 1421 to be separated and unfolded, and then is inserted into the locking hole 1311 on the lower supporting tube 131 to realize the positioning of the upper supporting tube 132.

Furthermore, the inner end edge of the top surface of the latch 141 is an oblique angle and is attached to the bottom end oblique surface of the pressing block 1421 to slide, which is beneficial to smoothly push the pair of latches 141 away when the pressing block 1421 moves down. The unlocking rod 143 is sleeved with a limiting piece 1323 near the bottom end thereof, a rectangular spring 145 is sleeved outside the bottom of the unlocking rod 143 and between the limiting piece 1323 and the pressing block 1421, and the lifted unlocking block 142 is pressed back by the resilience force of the rectangular spring 145, so that the bolt 141 is unfolded automatically, and the unlocking rod 143 is lifted up each time. A limiting groove 1322 inserted into the limiting piece 1323 is formed on the outer side of the upper supporting tube 132 and above the latch hole 1321, so that the limiting piece 1323 is positioned, and the rectangular spring 145 applies force to the unlocking block 142. The top end of the unlocking rod 143 is hung with a pull handle 144, the pull handle 144 penetrates through the outside of the upper supporting tube 132, and the outer end of the pull handle 144 is provided with a rectangular block for facilitating hand-carrying. The outside of the top of the upper supporting tube 132 is provided with a sliding slot 1324 which is inserted into the pull handle 144 and can slide, so that the movement of the pull handle 144 is limited, and the effective stroke of the unlocking block 142 is ensured.

When the bed plate is lifted, firstly the bed plate 100 is pushed to the outside of a carriage of an ambulance, then the front and rear personnel of the bed plate 100 grasp two side edges of the bed plate and pinch a pull handle 144 at the same time, and lift up an unlocking rod 143 and an unlocking block 142 to draw a pair of lock tongues 141, at this time, the force can be applied to lift the bed plate 100 to be higher than the carriage, then the bed plate 100 is pushed to enable one end of the bed plate 100 to extend into the carriage, so that the personnel in the carriage can contact with the bed plate 100, the personnel close to the fixed plate mechanism 120 can drive a push rod tongue 123 to move by using an external pull rod 124 so as to enable a fixed plate rod 121 to move to a narrow section of a push rod tongue 123 under the resilience of a pressure spring 122, and further the outer end of the fixed plate rod 121 is separated from a inserting rod groove 114, at this time, the front and rear personnel of the bed plate 100 firstly translate the bed plate to enable a slide block 101 to be right below a square groove 112, and then lift up the bed plate 100 to be placed in the carriage.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
