The spring 61 may take many different forms including, but not limited to, a compression spring, a torsion spring, or a clockwork spring, and the length of the spring 61 may be adjustable.
The bottom end of the spring chamber 6 is provided with a plugging member 64 for plugging the bottom end of the spring chamber 6. A plurality of adjustment recesses 65 are also provided on the outside of the spring magazine 6.
The spring chambers 6 on two sides are respectively provided with a stop lever 7, the stop lever 7 is fixed on the spring chamber 6 through a stop lever adjusting pin 71, wherein the stop lever adjusting pin 71 is matched with an adjusting groove 65 on the outer side of the spring chamber 6, the stop lever 7 is fixed on the spring chamber 6 through the stop lever adjusting pin 71 and the adjusting groove 65, and the position of the stop lever 7 on the spring chamber 6 can be adjusted through matching the stop lever adjusting pin 71 with different adjusting grooves 65. Wherein, a leg fixing band (not shown in the figure) is further arranged on the stop lever 7, and when the wearer wears the device, the stop lever 7 is fixed at the front position of the thigh above the knee of the wearer through the leg fixing band.
The specific working process of the embodiment of the utility model is as follows:
the wearer fixes the back through shoulder belt back stay tube 1 to fix two wire reels 4 respectively in the hip outside of both sides through the hip fixed band, fix two pin 7 respectively in the thigh front side above two knees about through the shank fixed band finally, pin 7 accessible pin 71 adjusts its position on spring chamber 6. When the wearer bends over, the waist pipe 2 and the spring chamber 6 use the wire reel 4 to rotate relatively as the axle, and wire reel 4 winds tight steel wire 31, because steel wire 31 length is fixed, consequently the both ends of steel wire 31 can upwards take up and compress the spring 61 in the spring chamber 6 of both sides, make spring 61 compressed and hold power, because both sides spring 61 establishes ties through same root steel wire 31, consequently, the size of the power that both sides spring 61 received is unanimous, can not influence the wearer and balance. At this moment, the compressed spring 61 enables the booster to generate a rotating torque at the wire spool 4, and when the wearer performs the straight waist action, the rotating torque provides the boosting force for the wearer to help the wearer to complete the straight waist action.
When a wearer walks, the steel wire 31 stretches back and forth due to the back and forth movement of the two legs, so that the stroke difference generated in the leg stepping process can be made up, and the spring is not compressed at the moment, so that the walking resistance cannot be generated.
When the wearer bends his legs back and forth, the springs 61 are connected in series by the single wire 31, so that the amount of deformation of the springs 61 is uniform, and the feeling of pressure applied to the legs is also uniform.
Compared with the prior art, the passive waist booster provided by the utility model can generate boosting force for the waist of a wearer through the stretching of the steel wires and the passive compression of the springs, does not need an external power source, has a simple and light structure, is convenient to maintain, and can play a role in balancing output force through connecting the two springs in series by one steel wire, so that legs of the wearer can not bear pressure when the wearer normally walks. Simultaneously, pivoted pedestal and can control pivoted spring chamber around can providing very big degree of freedom for the activity of wearing person's shank, avoid wearing person's shank activity to be restricted. The waist assisting device realizes waist assistance to a wearer through a simple structure, and is low in cost and wide in application.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
