DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-9The present invention provides a technical solution: a medical equipment fixing frame for helicopter rescue, comprising a frame plate 1, a plurality of guide rails 3 are fixedly installed on the frame plate 1, two adjacent guide rails 3 form a group, and a stretcher 4 is slidably connected to each group of guide rails 3, both ends of the two sides of the stretcher 4 are fixedly connected with sliders 31, one side of each slider 31 is fixedly connected with a guide wheel 30, a guide ring 41 acting on the guide rail 3 is arranged inside each slider 31, the top of the guide ring 41 extends into the inside of the slider 31, a second wedge 40 is fixedly connected to the top of the guide ring 41, and a top tube 37 is movably connected to the side of the guide ring 41, a first wedge 39 is fixedly connected to the side of the top tube 37 near one end of the second wedge 40, the first wedge 39 and the second wedge 40 are slidably matched together, and a plurality of sliding sleeves are movably connected to the middle of the bottom of each stretcher 4 33, each sliding sleeve 33 is swingably connected to a counterweight ball 34 at the bottom; a plurality of sliding sleeves 33 are commonly connected to a docking rod 38 on the same side, and both ends of the sliding sleeves 33 located at the head and tail of the stretcher bed 4 are fixedly connected to a connecting tube 35, and a second spring 36 is fixedly connected between each connecting tube 35 and the top tube 37; a weight-bearing cavity 43 is formed inside the slider 31 between the second wedge block 40 and the guide ring 41, and a plurality of rolling balls 42 are movably connected to each guide ring 41; when the helicopter is in the process of ascending, the vibration generated is inevitable, so the helicopter is different from the common passenger plane. The rotor of the helicopter will generate periodic vibration when rotating, and this vibration will be transmitted to the fuselage and the cockpit. The vibration frequency of the helicopter is much higher than that of the passenger plane. Therefore, in this case, the fixation of the stretcher bed 4 is improved as follows to enhance the patient's experience; When the stretcher 4 is installed on the guide rail 3, the ball 42 at the bottom of the slider 31 contacts the guide rail 3. The ball 42 and the guide ring 41 are in rolling connection. The ball 42 rolls on the guide ring 41 to reduce the friction between the guide ring 41 and the guide rail 3. Damping and shock-absorbing cotton materials can be installed inside the weight cavity 43. When the helicopter is flying in the air, the vibration generated is absorbed by the weight cavity 43. When the helicopter turns in the air, the turning of the helicopter propeller will cause the entire fuselage to tilt. Therefore, the side of the patient's body is in direct contact with the stretcher 4, which is easy to cause secondary injuries. In contrast, when the frame plate 1 of this bracket tilts, the counterweight balls 34 on the multiple sliding sleeves 33 in the middle of the bottom of the stretcher 4 are biased to the tilted side, so when the counterweight balls 34 tilt During the tilting process, it can drive the connecting tube 35 to slide at the bottom of the stretcher bed 4, and then the connecting tube 35 compresses the second spring 36, and the second spring 36 generates a thrust to squeeze the top tube 37. After the top tube 37 generates pressure, one end of the top tube 37 moves toward the inside of the slider 31, and then drives the first wedge block 39 connected to the end of the top tube 37 to press the second wedge block 40 to descend. When the second wedge block 40 descends, the second wedge block 40 can allow the ball 42 to rotate along the axial direction of the guide roller, so that the height of the slider 31 from the guide roller becomes larger, so that the slider 31 tending to tilt and the slider 31 on the other side of the stretcher bed 4 are close to the same height state, so that the stretcher bed 4 tends to be level with the ground, reducing the possibility of contact between the patient's side and the side of the stretcher bed 4, and improving the patient's comfort experience; In addition, the side of the stretcher bed 4 can be appropriately equipped with a three-point or five-point safety belt, thereby further reducing the risk to the patient.
