Detailed Description

Referring to fig. 1 to 5, a multifunctional shovel stretcher comprises a left half stretcher and a right half stretcher which are detachably connected, each half stretcher comprises an upper body frame 1, a lower body frame 2 and a connecting block 5 for connecting the upper body frame and the lower body frame, the inner side of the upper body frame 1 is rotatably connected with an upper shovel plate 3, and the inner side of the lower body frame 2 is provided with a lower shovel plate 4; supporting pins 8 are arranged on the inner side of the upper body frame 1 and above the upper shovel plate 3, and a lifting device 9 capable of leveling the lower concave upper shovel plate 3 is arranged between the two supporting pins 8.

It can be understood that the shovel stretcher composed of the upper body frame 1, the lower body frame 2, the upper shovel plate 3, the lower shovel plate 4 and the connecting block 5 is similar to other existing products on the market, and has the basic functions and arrangement of a conventional shovel stretcher, for example, the upper body frame 1 and the lower body frame 2 are telescopically connected through the connecting block 5, so as to adapt to users with different heights; for example, the upper body frame 1 and the lower body frame 2 are divided into a left part and a right part and are detachably connected through the buckle parts, so that the stretcher can be directly shoveled on the user from two sides of the body of the patient without lifting the patient. These are conventional techniques or conventional choices in the art, are well known to those skilled in the art, and are not important to the improvement of the present technical solution, and will not be described herein for a short time. It should be noted that the utility model discloses the most expensive technical core just lies in having set up and to have transferred into the hoisting device 9 of the leveling state with the last shovel board 3 of recessed state to this hoisting device 9 mainly utilizes the supporting pin 8 that the symmetry set up on the upper part of the body frame 1 can realize the function, and it is extremely convenient to upgrade the production facility of reforming transform conventional stretcher, and even it is also not troublesome to reform transform the finished product of current ordinary shovel stretcher, as for hoisting device 9's concrete form, the utility model discloses only show in the actual implementation most reliable, portable structure, other do not deviate from the utility model discloses the implementation form of technical idea obviously also should belong to the protection category of this patent.

Furthermore, the lifting device 9 includes an omega-shaped support rod 90 with a vertically upward protruding middle part, two ends of the support rod 90 are provided with adaptive support holes for inserting the support pins 8, the middle part of the support rod 90 is fixedly connected with a lifting box 91 corresponding to the position of the upper shovel plate 3, one side of the lifting box 91 close to the upper shovel plate 3 is vertically provided with a rack 92 penetrating through the top surface and the bottom surface of the lifting box 91, the bottom end of the rack 92 is provided with a lifting pin 93, the lifting pin 93 is perpendicular to the rack 92 and extends into the upper shovel plate 3, and the end surface of the upper shovel plate 3 is provided with a lifting hole for inserting the lifting pin 93 and allowing the lifting pin 93 to move left and right corresponding; the lifting box 91 is provided with a lifting mechanism for driving the rack 92 to lift. It can be understood that the supporting rod 90 is provided with the omega-shape with the middle part vertically protruding upwards, so that the operation of the parts arranged in the middle part can be facilitated, meanwhile, a necessary space is provided for the manual operation of the emergency personnel, and the supporting holes are arranged at the two ends of the supporting rod 90 so as to be matched by the supporting pins 8, so that a sufficient supporting force is provided for the upper shovel plate 3 to be adjusted to be in a straight state. The lifting box 91 is equivalent to a shell of a lifting mechanism, and provides support and protection for the lifting mechanism, and the rack 92 drives the lifting pin 93 to move through the movement of the lifting mechanism, because the lifting pin 93 is inserted into a lifting hole of the upper shovel plate 3, the upper shovel plate 3 is naturally driven to lift until the lifting pin is converted into a straight spinal plate state, because the upper shovel plate 3 rotates around the upper body frame 1 in the lifting process, and therefore the lifting hole is set into a long circular groove, a waist-shaped groove, a curved groove and other shapes which can be used for the lifting pin 93 to move left and right.

Further, the lifting mechanism comprises a driven gear 94 engaged with the rack 92, and the driven gear 94 is arranged perpendicular to the support rod 90 and is rotatably connected with the lifting box 91 through a driven rotating shaft 95; the lifting box 91 is also provided with a driving gear 96 engaged with the driven gear 94, and the driving gear 96 is rotatably connected with the lifting box 91 through a driving rotating shaft 97. Furthermore, one end of the driving rotating shaft 97, which is far away from the upper shovel plate 3, penetrates through the lifting box 91 and vertically penetrates through the supporting rod 90, a rocking handle 98 is arranged at the overhanging end of the driving rotating shaft 97, and a positioning rod 99, which can penetrate through the rocking handle 98 and be inserted into the supporting rod 90, is arranged on the rocking handle 98. It will be appreciated that the lifting mechanism functions very specifically, i.e., the lifting pin 93 is actuated, and therefore the present embodiment is only an example of the most common gear train, crank 98 drive mechanism, showing one mechanism for actuating the lifting pin 93, but other possible ways may be used: for example, one end of the lifting pin 93 which extends out of the upper shovel plate 3 is provided with a pull rope, the other end of the pull rope is provided with a winding and unwinding wheel, and the winding wheel rotates through a rocking handle 98; for example, the overhanging end of the lifting pin 93 is directly and vertically fixedly connected with a vertically arranged telescopic cylinder; for example, the driving device is driven by a micro motor replaced by the manual crank 98 and is adapted to a power supply, and other feasible mechanisms for realizing the action of the lifting pin 93 can be adopted, and the specific embodiments can be reasonably selected according to actual conditions and requirements. In addition, the positioning rod 99 is provided for adjusting the upper shovel plate 3 to a proper position by the rocking handle 98, and the positioning rod 99 is inserted into the supporting rod 90 to prevent the rocking handle 98 from rotating reversely to realize position locking, so that a safe and stable plane is provided for a user, and locking can be realized by a gear rotation stopping wedge block applied to a meshing area, a rotation stopping chuck applied to a gear surface and other mechanisms.

Further, the driving gear 96 and the rack 92 are located on the same side of the driven gear 94, and the thickness of the driven gear 94 is greater than the sum of the thicknesses of the driving gear 96 and the rack 92. It will be appreciated that the rack gear 92, the driven gear 94 and the pinion gear 96 may be distributed in a variety of ways, and the position relationship and thickness parameters described in the present embodiment may allow the lifting mechanism and the lifting box 91 to be smaller and more portable and storable.

Further, the diameter of the driven gear 94 is smaller than the diameter of the driving gear 96. It can be understood that such an arrangement allows for quick switching and adjustment of the straight scoop stretcher and is more labor efficient in manual rotation.

Furthermore, a plurality of restraining belt holes 6 are arranged at the position of the upper shovel plate 3 close to the upper body frame 1 and the position of the lower shovel plate 4 close to the lower body frame 2. It can be understood that the restraining belt holes 6 are arranged to facilitate the installation and fixation of the restraining belts.

Further, a plate surface of the upper shovel plate 3 near one end of the supporting pin 8 is provided with a head lock mounting hole 7. It will be appreciated that the head lock mounting hole 7 may be provided to add a head lock when desired, providing more complete securement and care for the user.
