The working principle of the adsorption fixing device 1 is explained below on the basis of two embodiments:
when a patient needs to be transferred to the stretcher 3 or transferred downwards from the stretcher 3, the operation handle 155 is pulled to release the locking of the power shaft 12 and simultaneously operate the operation rod 14 of the driving mechanism 1, so that the whole floating sucker mechanism 2 moves vertically downwards, and the movement is stopped when the sucker 23 is close to the ground surface; at the moment, the chock 22 continues to move downwards and is inserted into the exhaust hole 231, the suction cup 23 is sealed, the suction cup 23 is further fixed to the ground in a suction mode, meanwhile, the stretcher 3 is fixed, at the moment, the locking pin 152 is inserted into the corresponding pin hole 122 (the lower pin hole 122) under the action of the elastic force of the return spring 154, and the power shaft 12 is locked in position (the fixed position is locked); the stability of the stretcher 3 in the process of transferring the patient is ensured, and the patient is prevented from being injured due to the shaking of the stretcher 3.
When the stretcher 3 is not needed, pulling the operating handle 155 unlocks the power shaft 12 and operates the operating lever 14 of the drive mechanism 1; at this time, because the suction force of the suction cup 23 to the ground is large, when the power shaft 12 drives the mounting plate 21 to vertically move upwards, the suction cup 23 is temporarily not moved, the chock 22 is firstly released from the exhaust hole 231, the sealed suction cup 23 leaks air, the suction force between the suction cup 23 and the ground is weakened, then the suction cup 23 is separated from the ground under the driving of the power shaft 12, at this time, the locking pin 152 is inserted into the corresponding pin hole 122 (in the pin hole 222 above) under the elastic action of the return spring 154, and the power shaft 12 is locked in position (locking at the separated position); further, the release of the stretcher 3 is realized.
In conclusion, the utility model has simple and compact structure, rapid and simple operation, and can realize the fixation or the release of the fixation of the body and the ground without changing the structure of the body of the prior stretcher; the stability of the stretcher during the patient transferring process is ensured, and the patient is prevented from being injured due to the shaking of the stretcher; is convenient for popularization and promotion.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
