In the invention, the unfolding device 9 comprises three connecting battens 901, the three connecting battens 901 are arranged in parallel, and the connecting battens 901 on the left and right sides are respectively and fixedly connected with the side frames 1 on the left and right sides.

The surface that links up lath 901 has seted up guide way 902, and the inboard swing joint of guide way 902 has guide bar 903, and the fixed surface that links up lath 901 is connected with locating lever 904, and folding rod 905 has been cup jointed in the activity of locating lever 904 surface, and folding rod 905's end and guide bar 903 are fixed to be cup jointed, and folding rod 905 is the crossing setting, and the middle part of two crossing folding rods 905 is through linking pole 906 swing joint. It should be noted that the two intersecting folding bars 905 have a cross-scissors structure, and when the guide bar 903 slides inside the guide groove 902, the distance between the left and right side frames 1 becomes smaller, whereas when the left and right side frames 1 are pulled, the guide bar 903 can slide inside the guide groove 902. Damping rubber is sleeved among the guide rods 903, the positioning rods 904 and the folding arms, and under the condition that the side frames 1 are pulled non-manually, included angles among the folding arms can be locked and maintained.

In the invention, the upper end and the lower end of the guide rod 903 are fixedly sleeved with limiting pieces, and the limiting pieces are in sliding connection with the surfaces of the connecting laths 901. It should be noted that the connection effect between the folding arm and the connecting lath 901 is enhanced by the limiting piece.

In the invention, the supporting device 10 comprises a rotating shaft 1001, one end of the rotating shaft 1001 is fixedly connected to the surface of the side frame 1, the surface of the rotating shaft 1001 is rotatably connected with a swinging arm 1002, the top end of the swinging arm 1002 is movably connected with a handrail 1003, the front end of the handrail 1003 is rotatably connected with a parallel arm 1004, and the bottom end of the parallel arm 1004 is rotatably connected to the surface of the side frame 1.

The bottom fixedly connected with supporting seat 1005 of side frame 1, the figure of supporting seat 1005 is two, the side setting around two supporting seats 1005 is, the surface rotation of rear side supporting seat 1005 is connected with supports loop bar 1006, the sliding sleeve 1007 has been cup jointed in the surface activity of supporting loop bar 1006, the bottom of sliding sleeve 1007 is articulated with the bottom of swing arm 1002, the surperficial swing joint of sliding sleeve 1007 has pull rod 1008, the front end of pull rod 1008 is articulated to have a support pendulum rod 1009, the top of supporting pendulum rod 1009 rotates with the supporting seat 1005 of front side to be connected.

The bottom ends of the support swing rod 1009 and the support sleeve rod 1006 are movably connected with the moving wheel 11. It should be noted that a telescopic rod is movably connected between the left and right support swing rods 1009, the telescopic rod is composed of two outer tubes and an inner tube, the two outer tubes are respectively sleeved on the left and right sides of the inner tube, and the ends of the two outer tubes, which are opposite to each other, are respectively fixedly connected with the left and right support swing rods 1009.

In the invention, the parallel arm 1004, the armrest 1003, the top of the swing arm 1002 and the side frame 1 form a parallelogram structure together.

In the invention, a notch is formed in the front side surface of the swing arm 1002, which is close to the rotating shaft 1001, a pin hole is formed in the surface of the side frame 1, a pin rod is inserted and sleeved in the pin hole, and the pin rod and the notch are matched with each other. It should be noted that when the notch and the pin rod are abutted against each other, the back swing action of the top end of the swing arm 1002 is limited, and is affected by the pressure of the side frame 1 and the device itself, the support sleeve rod 1006 and the support swing rod 1009 maintain the flare angle expansion trend, so that the top end of the swing arm 1002 maintains the back swing trend, and when the device is loaded, the swing arm 1002 and the pin rod maintain the abutted state, and further the flare angle between the support sleeve rod 1006 and the support swing rod 1009 is locked.

During the use, push the handrail 1003 upwards and open, because the handrail 1003, parallel arm 1004, side frame 1 and swing arm 1002 are the parallelogram structure, swing arm 1002 uses rotation axis 1001 as the downward action of deflecting of centre of a circle, the bottom of swing arm 1002 pulls the sliding sleeve 1007 and slides downwards in supporting the surface of loop bar 1006, make supporting loop bar 1006 deflect backward, and meanwhile, the sliding sleeve 1007 pulls pull rod 1008 and drives and support pendulum bar 1009 and overturn downwards, supporting loop bar 1006 and supporting pendulum bar separate and be the trapezium structure with side frame 1, movable wheel 11 contacts ground, after the top of swing arm 1002 leans forward through the pinhole, peg rod is pegged graft to the pinhole inboard, make the surface of peg rod and the notch butt of swing arm 1002 top rear side, realize supporting loop bar 1006 and the locking of supporting the pendulum bar 1009 and supporting the opening angle size of pendulum bar 1009, realize supporting loop bar 1006 and the bearing support effect of supporting pendulum bar to side frame 1 of supporting loop bar 1006.

On the contrary, the pin rod is released from abutting against the rear side of the swing arm 1002, the handrail 1003 is pushed backwards, the supporting sleeve rod 1006 and the supporting swing rod 1009 can be driven to be overturned towards the surface of the side frame 1 to be attached, and folding storage and reduction of occupied volume of the whole space of the equipment are achieved.

During length adjustment, the turn buckle 803 is rotated, the distance between the front end and the rear end of the turn buckle 803 is increased, the turn buckle 803 drives the connecting rod 801 on the front side and the rear side to move away from each other, the connecting rod 801 and the extension arm 5 slide on the inner side of the track frame 2, the change of the distance between the supporting plates 6 on the front side and the rear side is realized, and the integral length adjustment of the equipment is realized.

During angular adjustment, at first rotatory turn buckle 803 to its front and back side end between the interval longest, make connecting rod 801 break away from the direction restriction in track groove 3, receive the restraint of activity post 4, the end of extension arm 5 remains in track frame 2 inboard throughout, because the setting in deflection groove, make extension arm 5 can use activity post 4 to produce the action of deflecting as the centre of a circle, the extension arm 5 of front side can the lower hem, the extension arm 5 of rear side can the upper hem, rotatory turn buckle 803 can adjust the front and back side and extend arm 5 for the inclination between the side frame 1, the interval between the turn buckle 803 front and back end is less, the contained angle between extension arm 5 and the side frame 1 is less, extension arm 5 is close to the vertical state more for side frame 1. In this way, a change in the surface trend of the device is achieved.

During width adjustment, the side frames 1 on the left side and the right side are pulled in opposite directions, the folding rods 905 are pulled by the side frames 1 to generate scissor action, so that the guide rods 903 slide in the guide grooves 902, meanwhile, the distance between the left side extension arm 5 and the right side extension arm 5 is increased under the influence of the pulling action of the side frames 1, the distance between the left side support plate 6 and the right side support plate 6 is increased, the extension plates 7 are pulled out from the left side support plate 6 and the right side support plate 6, and the whole width of the equipment is adjusted.

Through the adjustment of length, angle and width for meeting patient's size posture demand that this equipment can be better, can match the patient of different size characteristics, it is stronger to use the suitability, and the result of use is better.
