[0031] In this embodiment, the structure of the locking mechanism includes: a front fixing seat 24 is fixed on the side wall 4 of the carriage at the front swing arm 2, a front locking block 25 is provided on the front fixing seat 24, the front locking block 25 is hinged to the front fixing seat 24 through a front fourth vertical axis 26, and the front locking block 25 has a locking hook part and a driving part distributed on both sides of the front fourth vertical axis 26; a front snap-in opening 27 for the locking hook part of the front locking block 25 to snap into is provided on the front swing arm 2;

[0032] A rear fixing seat 28 is fixed on the side wall 4 of the carriage at the rear swing arm 3, and a rear locking block 29 is provided on the rear fixing seat 28. The rear locking block 29 is hinged to the rear fixing seat 28 through a rear third vertical axis 30, and has a locking hook portion and a driving portion distributed on both sides of the rear third vertical axis 30; a rear bayonet 31 for the locking hook portion of the rear locking block 29 to be clamped is provided on the rear swing arm 3;

[0033] A long rod 32 is connected between the driving part of the front swing arm 2 and the driving part of the rear swing arm 3, and the two ends of the long rod 32 are respectively hinged with the driving part of the front swing arm 2 and the driving part of the rear swing arm 3. A mounting seat 33 is fixed on the side wall 4 of the car body in front of the front swing arm 2, and a sleeve 34 is fixed on the mounting seat 33. One end of the wire rope 35 passes through the sleeve 34 forward and a handle 36 is fixed thereon. The other end of the wire rope 35 passes through the sleeve 34 backward and is connected to the front end of the long rod 32. A spring 37 is sleeved on the outside of the wire rope 35 between the sleeve 34 and the long rod 32. One end of the spring 37 abuts against the front end of the long rod 32, and the other end of the spring 37 abuts against the sleeve 34. The spring 37 makes the long rod 32 always have a tendency to move backward so that the front locking block 25 and the rear locking block 29 always have a tendency to rotate and snap into the corresponding snap-in slots of the corresponding swing arms. The above locking mechanism has a simple structure and is easy to install and maintain.

[0034] In this embodiment, the rear end of the sleeve 34 has an external thread 40, and an adjusting nut 41 is threadedly connected to the external thread 40 of the sleeve 34. One end of the spring 37 abuts against the adjusting nut 41, and the other end abuts against the front end of the long rod 32. By adjusting the position of the adjusting nut 41, the elastic force of the spring 37 acting on the long rod 32 can be adjusted synchronously, ensuring that when the external force applied to the handle 36 is removed, the spring 37 can make the long rod 32 move backward so that the front locking block 25 and the rear locking block 29 are rotated and snapped into the corresponding snap-in holes of the corresponding swing arms, thereby locking the front swing arm 2 and the rear swing arm 3, and the operation is more convenient.

[0035] In this embodiment, an auxiliary lifting mechanism is provided between the front swing arm 2 and the side wall 4 of the carriage to assist the stretcher compartment 1 to be folded to the side wall 4 of the carriage; the structure of the auxiliary lifting mechanism includes: a notch is provided at the inner end of the front swing arm 2 which is sleeved with the vertical guide rod 5, one end of the lifting block 38 extends from the notch and is movably sleeved on the vertical guide rod 5, so that the lifting block 38 can move up and down along the vertical guide rod 5, the other end of the lifting block 38 is hinged to the upper end of the gas spring 39, the lower end of the gas spring 39 is hinged to the side wall 4 of the carriage, and the gas spring 39 applies an upward moving force to the front swing arm 2 through the lifting block 38 to assist the stretcher compartment 1 to be folded to the side wall 4 of the carriage, so that medical staff can more conveniently fold the stretcher compartment to the side wall of the carriage, which is more convenient to use;

[0036] When lowering the stretcher compartment:

[0037] First, the locking mechanism releases the lock of the front swing arm 2 and the rear swing arm 3. The specific operation is: pull the handle 36 forward, and the handle 36 drives the long rod 32 to move forward through the wire rope 35. During the forward movement of the long rod 32, the front locking block 25 and the rear locking block 29 are simultaneously driven to rotate outward around the corresponding vertical axis to disengage from the corresponding bayonet. That is, when the front locking block 25 is disengaged from the front bayonet 27 and the rear locking block 29 is disengaged from the rear bayonet 31, the front swing arm 2 and the rear swing arm 3 are in an unlocked state where they can move;

[0038] Then, the front end of the stretcher compartment 1 is pulled outwards. In the process of the stretcher compartment 1 moving outwards away from the side wall of the vehicle compartment, under the limiting action of the adjustment rod 16, the front swing arm 2 gradually moves downwards along the vertical guide rod 5, so that the stretcher compartment 1 gradually tilts downwards until the stretcher compartment 1 is completely in a tilted and lowered posture for easy loading of the stretcher;

[0039] The principle of the limit of the adjusting rod 16 is explained in detail below:

[0040] Since the rotation center of the front swing arm 2 is the vertical guide rod 5, and the lower connector 14 hinged to the lower end of the adjusting rod 16 is installed on the front swing arm 2, during the rotation of the front swing arm 2 around the vertical guide rod 5, the rotation trajectory of the lower end of the adjusting rod 16 is forced to be in the trajectory circle a with the vertical guide rod 5 as the center (the trajectory circle a is as shown in FIG. Fig. 9 , Fig.14 At the same time, the upper end of the adjusting rod 16 is hinged to the outer end of the cross-connecting plate 10;

[0041] In this way, when the front swing arm 2 rotates outward around the vertical guide rod 5, the lower end of the adjusting rod 16 will rotate outward along the track circle a. When the lower end of the adjusting rod 16 rotates outward along the track circle a, the distance between the lower end of the adjusting rod 16 and the track circle a will become shorter; at this time, the lower end of the adjusting rod 16 can only move downward in order to be in the track circle a, thereby synchronously driving the front swing arm 2 to move downward along the vertical guide rod 5; thereby, the stretcher compartment 1 is in a tilted lowered posture for easy loading of the stretcher;

[0042] When folding up the stretcher compartment:

[0043] The front end of the stretcher compartment 1 is pushed inwardly toward the side wall of the carriage. During the inward movement of the stretcher compartment 1, under the limiting action of the adjustment rod 16, the front swing arm 2 gradually moves upward along the vertical guide rod 5, so that the stretcher compartment 1 is gradually laid flat, until the stretcher compartment 1 is stored against the side wall of the carriage in a flat use posture;

[0044] The principle of the limit of the adjusting rod 16 is explained in detail below:

[0045] Since the rotation center of the front swing arm 2 is the vertical guide rod 5, and the lower connector 14 hinged to the lower end of the adjusting rod 16 is installed on the front swing arm 2, during the rotation of the front swing arm 2 around the vertical guide rod 5, the rotation trajectory of the lower end of the adjusting rod 16 is forced to be in the trajectory circle a with the vertical guide rod 5 as the center (the trajectory circle a is as shown in FIG. Fig. 9 , Fig.14 At the same time, the upper end of the adjusting rod 16 is hinged to the outer end of the cross-connecting plate 10;

[0046] In this way, when the front swing arm 2 rotates inwardly around the vertical guide rod 5, the lower end of the adjusting rod 16 will rotate inwardly along the track circle a. When the lower end of the adjusting rod 16 rotates inwardly along the track circle a, the distance between the lower end of the adjusting rod 16 and the track circle a will become longer; at this time, the lower end of the adjusting rod 16 can only move upwardly in order to be in the track circle a, thereby synchronously driving the front swing arm 2 to move upwardly along the vertical guide rod 5; so that the stretcher compartment 1 is in a flat use posture;

[0047] When the stretcher compartment is in a flat usage posture, the external force applied to the handle 36 is removed. At this time, the long rod 32 will move backward under the elastic force of the spring 37. During the backward movement of the long rod 32, the front locking block 25 and the rear locking block 29 will be driven to rotate inward around the corresponding vertical axis and snap into the corresponding snap-in slots of the corresponding swing arms. That is, when the front locking block 25 snaps into the front snap-in slot 27 and the rear locking block 29 snaps into the rear snap-in slot 31, the front swing arm 2 and the rear swing arm 3 are locked. At this time, the stretcher compartment 1 can be stably stored on the side wall of the car compartment.

[0048] The utility model has the advantages that before the stretcher is loaded onto the vehicle, the stretcher compartment can be placed in an inclined and lowered posture for easy loading of the stretcher onto the vehicle, and after the stretcher is loaded onto the vehicle, the stretcher compartment can be placed in a flat usage posture and folded onto the side wall of the vehicle compartment, so the operation and use are convenient.

[0049] The above description is only a preferred embodiment of the present invention and does not constitute any other limitation on the present invention. Any modification or equivalent change made based on the technical essence of the present invention still falls within the scope of protection required by the present invention.
