Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5, including base 1, base 1 left side is fixed with the bracing piece 2 of vertical direction and the type of falling L, 2 right side lower extremes of bracing piece are equipped with arc 3, the groove of stepping down 4 that the direction just controlled and link up about seted up on bracing piece 2, be equipped with the rack 5 of vertical direction on the lateral wall before the groove of stepping down 4, sliding connection has rectangular frame 6 on the bracing piece 2, it is connected with about axial pivot 7 to rotate on the 6 left side walls of rectangular frame, 7 right-hand members of pivot stretch into in the groove of stepping down 4 and be equipped with can with rack 5 meshed

gear

8, 6 right sides of rectangular frame are equipped with down arc 9, it is relative with lower arc 9 arc mouth to go up arc 3.

In order to limit the position of the rectangular frame 6 moving up and down, the left side of the rectangular frame 6 is provided with a plurality of positioning holes 10 uniformly distributed along the circumferential direction of the rotating shaft 7, the rotating shaft 7 is connected with a positioning disc 11 in a sliding way, and a positioning needle 12 capable of being inserted into the positioning holes 10 is fixed on the positioning disc 11.

In order to increase the stability of the lower arc-shaped plate 9, a seat body 13 is fixed on the right side of the base 1, a sliding groove with an upward opening is formed in the seat body 13, a sliding rod 14 is fixed at the lower end of the lower arc-shaped plate 9, the sliding rod 14 is slidably connected with the sliding groove, a bolt knob 15 is connected to the right side wall of the seat body 13 in a threaded manner, and the left end face of the bolt knob 15 can be in contact with the right side face of the sliding rod 14.

In order to increase the comfort of the patient in use, the opposite surfaces of the upper arc-shaped plate 3 and the lower arc-shaped plate 9 are respectively provided with a cotton pad 16.

The positioning plate 11 is connected with the rotating shaft 7 through a guide key in the left-right direction.

In order to rotate the rotating shaft 7 conveniently, a hand wheel 17 is arranged at the free end of the rotating shaft 7.

When the utility model is used, the fracture part of a patient is placed on the lower arc-shaped plate 9, the bolt knob 15 is unscrewed, the left end of the bolt knob 15 is separated from the extrusion of the slide bar 14, the positioning disc 11 slides leftwards, the positioning disc 11 drives the positioning needle 12 to move out of the positioning hole 10, the hand wheel 17 is rotated, the hand wheel 17 enables the gear 8 to be meshed with the rack 5 through the rotating shaft 7, and the rack 5 is fixedly connected with the support rod 2, so the gear 8 moves upwards in the abdicating groove 4, the rotating shaft 7 drives the rectangular frame 6 and the lower arc-shaped plate 9 to move upwards, and the arc-shaped plate pushes the affected limb to move upwards;

when the cotton pad 16 on the last arc 3 contacts with the upper surface of suffering from the limb, when going up arc 3 and lower arc 9 and will suffering from the limb tight, stop rotating hand wheel 17, and promote positioning disk 11 rightwards, positioning disk 11 promotes in the locating pin 12 inserts corresponding locating hole 10, alright prevent that lower arc 9 is unexpected to glide down, in order to ensure that lower arc 9 supports the stability of suffering from the limb, again with bolt knob 15 screw, realize carrying out effectual interim fixed to suffering from limb fracture position, and the height of base 1 and slide bar 14 highly be enough to realize raising patient's suffering from the limb, effectively alleviate the downflow silting of blood at low limbs or foot.

When the fixation of the affected limb needs to be released, the bolt knob 15 is unscrewed, the positioning disc 11 is pulled leftwards, the lower arc-shaped plate 9 can move downwards by reversely rotating the hand wheel 17 after the positioning needle 12 is moved out of the positioning hole 10, the distance between the lower arc-shaped plate 9 and the upper arc-shaped plate 3 is increased, the fixation of the affected limb is released, the operation is simple, and the rescue time is won for the patient.
