Specific embodiment

The utility model is described further referring to attached drawing.

As shown in Figure 1, a kind of composite material scoop stretcher of sandwich structure, includes bracket 1 and connect with bracket 1 Shovel board 2, bracket 1 include head supporting frame 11, body portion support frame 12 and thigh support frame 13, shovel board 2 include head plate 21, Body 22 and leg plate 23, head supporting frame 11 are fixedly connected with head plate 21, and body portion support frame 12 and body 22 are fixed, leg branch Support 13 and leg plate 23 are fixed, and 22 length of body is much larger than head plate 21.

As shown in Figure 1 and Figure 2, plug-in connection 4 includes inserting groove 41 and grafting block 42.Inserting groove 41 is overall to be square, and inserts Fastening bar 411 is provided between 41 two sides of access slot, fastening bar 411 and inserting groove 41 are fixed.Fastening slot is provided on grafting block 42 43, it fastens and is extended with hinge bar 47 in slot 43, hinge bar 47 is hinged with card adapter plate 44, between card adapter plate 44 and fastening 43 bottom of slot It is connected with fixed spring 46.The side of grafting block 42 towards fastening bar 411 is provided with inclined end face, and card adapter plate 44 is towards inserting groove One end of 41 bottoms, which generates, clamping portion 45, and one side of the clamping portion 45 far from fastening bar 411 is inclined-plane, and clamping portion 45 is far from grafting The one side of 41 bottom of slot is plane.When installation, grafting block 42 enters in inserting groove 41, and fastening bar 411 squeezes the oblique of grafting block 42 Face squeezes card adapter plate 44 along inclined-plane, and slight deformation occurs for grafting block 42, and card adapter plate 44 is rotated around hinged place, so that fastening Bar 411 enters in fastening slot 43, and after clamping, card adapter plate 44 is located in fastening slot 43 far from one end of fastening bar 411, blocks when pushing The one end of fishplate bar 44 far from fastening bar 411, the rotation of card adapter plate 44 are that releasable fastening bar 411 realizes disassembly.Head supporting frame 11 With plug-in connection 4 is provided on thigh support frame 13.

As shown in Figure 1, Figure 3, thigh support frame 13 is inserted in body portion support frame 12, and socket part is provided with gas spring 16, body It is provided with the cylinder of gas spring 16 on portion's support frame 12, the piston of gas spring 16 is fixed on thigh support frame 13, is located at gas bullet Sleeve 17 is cased on the outside of spring 16,17 side wall of sleeve is provided with control seam 18, the switch 19 of gas spring 16, gas are provided in control seam 18 The setting of spring 16 is pressed out so that the length adjustment between the thigh support frame 13 and body portion support frame 12 of stretcher is more convenient 19 i.e. controllable gas springs 16 are closed to open.

As Figure 1 and Figure 4, head supporting frame 11 divides for left head frame 111 and right head frame 112, and body portion support frame 12 divides for a left side Stature 121 and right stature 122, thigh support frame 13 divide for left leg support 131 and right leg support 132.Head plate 21 is divided for left 21 He of head plate Right head plate 21, left head plate 21 and right head plate 21 are mirror symmetry；Body 22 divides for left body plate 22 and right body 22,22 He of left body plate Right body 22 is mirror symmetry, and one end of body 22 towards head plate 21 is provided with telescopic chute 14, and telescopic chute 14 extends body 22, prolongs It stretches place and is extended with pars contractilis 15 positioned at head supporting frame 11, the diameter of pars contractilis 15 is less than the internal diameter of telescopic chute 14, pars contractilis 15 It is inserted into telescopic chute 14, the distance being inserted into telescopic chute 14 by changing pars contractilis 15 has reached adjustment stretcher length to adapt to The effect of the patient of different heights.

As Figure 1 and Figure 4, the outside of telescopic chute 14 is extended with fixation kit 3 on body 22, and fixation kit 3 includes It abuts block 31 and abuts the fixed link 32 that block 31 is connected with, fixed link 32 passes through telescopic chute by the aperture of 14 side wall of telescopic chute 14, the outside that the pars contractilis 15 of telescopic chute 14 is located at fixed link 32, which generates, fixed column 33, and 32 outer end of fixed link is hinged with cam 34。

As shown in figs. 4 and 6, cam 34 is abutted with 33 top surface of fixed column, and the abutting part 37 of plane is provided on cam 34, Abutting part 37 increases cam 34 in planar, abutting part 37 and 33 plane contact of fixed column, the setting of abutting part 37 convenient for fixing Stability.It is provided with abutment ring 331 in fixed column 33, abutment ring 331 is provided with holddown spring 332 with abutting between block 31, Holddown spring 332 is in impaction state, will abut block 31 and presses to pars contractilis 15.When cam 34 rotates, cam 34 and fixed column 33 top end faces distance is different, changes the lifting to drive fixed link 32 by distance, changes the pressure for abutting block 31 and pars contractilis 15 Tight degree.It should be noted that the planar ends width of abutting part 37 is smaller, when dog-ear and 33 top surface of fixed column of abutting part 37 are supported Connect when turning to the planar ends of abutting part 37 and being abutted with 33 top surface of fixed column, the axle center that cam 34 rotates to 33 top surface of fixed column it Distance between although is shortened, and pars contractilis 15 can still be compressed by abutting block 31, so that pars contractilis 15 is in telescopic chute 14 Interior stabilization.One end of cam 34 is fixed with press section 35, and press section 35 is plate-like, and press section 35 is located at the tip of cam 34, Gu The fixing groove 36 being provided on fixed column 33, the width of fixing groove 36 is of same size with press section 35, and the setting of press section 35 is convenient for Cam 34 rotates, and press section 35 is fixed after press section 35 is pressed into fixing groove 36 after rotating by cam 34.Abutting block 31 at this time Pars contractilis 15 is compressed, so that the length of scoop stretcher is fixed.

As shown in figure 5, body 22 is the structure of packing material in shell, it include carbon fiber skin 5 and internal filling Sandwich foam 6.The weight of stretcher is alleviated using sandwich structure combination, while central filler light foam material is convenient for reinforcement load Structural strength of frame when hollow, plays and not only mitigates weight, but also increases the effect of structural strength.

The specific operation process of the utility model are as follows:

Left body plate 22 is placed in the left side of patient, right body 22 is placed in the right side of patient, two medical staff push left Body 22 and right body 22, so that the scoop structure of body 22 scoops up patient, until the clamping knot between head supporting frame 11 Clamping mechanism between structure and thigh support frame 13 is completed to be clamped.When the height of patient is too long, press section 35 is rotated, is driven Cam 34 rotates, so that abutting block 31 leaves pars contractilis 15, then adjusts the distance that pars contractilis 15 is inserted into telescopic chute 14, adjusts and completes Pars contractilis 15 is compressed so that abutting block 31 in rotation figure wheel afterwards, plays and adjusts the distance between head plate 21 and body 22, if while When patient legs are too long, the switch 19 of gas spring 16 on leg plate 23 is pressed, thigh support frame 13 slowly extends, and increases leg plate 23 The distance between body 22.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model Within the scope of.
