Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, there will now be described in detail, with reference to the accompanying drawings, a non-limiting detailed description of the present invention.
Referring to fig. 1, the liftable lower limb lifting support of the present embodiment includes a frame body 1, four telescopic rod assemblies 2, and a support net 3. The frame body 1 comprises two cross rods 10, four supporting legs 11 and two connecting rods 12, wherein the four supporting legs 11 are respectively hollow and cylindrical and are respectively arranged at two ends of the two cross rods 10 and can be integrally formed. The four telescopic rod components 2 are respectively arranged in the four supporting legs 10 and used for adjusting the height of the frame body 1. The support net 3 is arranged on the two cross rods 1 of the frame body 1 and is used for supporting the lower limbs of the human body.
Referring to fig. 2, the telescopic rod assembly 2 comprises an outer sleeve 20, a friction pad 21, a rotating shaft 22 and a tension ring 23. The outer sleeve 20 is mainly used for accommodating the friction pad 21, the rotating shaft 22 and the tension ring 23. The friction pad 21 is mainly used for friction limiting with the inner wall of the supporting foot 11. The rotating shaft 22 is mainly used for driving the tension ring 23 to rotate. The tension ring 23 is mainly used for pressing the friction pad 21 to be tightly attached to the inner wall of the supporting leg 11, so as to increase the friction force.
The outer sleeve 20, see fig. 3, is hollow cylindrical and open at both ends. Two symmetrical openings 200 are formed on the sidewall of the upper portion of the outer sleeve 20, and the two sets of adjacent ends of the two openings 200 are spaced equally. The projections of the two openings 200 are rectangular, the axial direction is the length, the radial direction is the width, and the length is larger than the width. A scale may be provided on the outer wall of the outer sleeve 20.
Referring to fig. 4, the friction pad 21 is disposed within the outer sleeve 20 and faces the opening 200. The friction pad 21 has an overall circular ring shape, and includes two pad bodies 210 and two belt bodies 211. The two cushion bodies 210 are the same, are rubber elastic thick cushion bodies, are both arc-shaped, and are matched with the shapes and sizes of the two openings 200. One end of the pad body 210 is thicker than the other end, i.e., one end is a thick end and the other end is a thin end, and the thickness ratio can be 2: 1. When installed, the two pads 210 are respectively disposed at the two openings 200 of the outer sleeve 20, and the end walls are in contact with the side walls of the openings. The two belts 211 are the same, are rubber elastic thin belts, and have folds and good ductility. The two belt bodies 211 are respectively connected between the two cushion bodies 210 to form a circular ring shape of the friction cushion, and the connection mode is as follows: one end of one belt body is connected with the middle part of the thick end of one cushion body, the other end is connected with the inner side of the thin end of the other cushion body, one end of the other belt body is connected with the inner side of the thin end of one cushion body, and the other end is connected with the middle part of the thick end of the other cushion body. Whether thick ends or thin ends are connected, the distance from the outer side wall of the cushion body to the connection position of the belt body is equal.
Referring to fig. 5, the rotation shaft 22 is rotatably inserted into the outer sleeve 20, and includes a shaft body 220, a stopper ring 221, and a foot pad 222. The shaft body 220 has a cylindrical shape having an outer diameter smaller than an inner diameter of the outer sleeve 20, is inserted into the outer sleeve 20, and is freely rotatable. The retainer ring 221 is disposed outside the outer sleeve 20 and detachably coupled to the upper end of the shaft body 220 by a screw connection, and the outer diameter of the retainer ring 221 is greater than the inner diameter of the outer sleeve 20 and equal to or less than the outer diameter of the outer sleeve 20. A foot 222 is located outside the outer sleeve 20 and detachably coupled to a lower end of the shaft body 220 by a screw coupling, and the foot 222 has an outer diameter greater than an inner diameter of the outer sleeve 20 and equal to or smaller than an outer diameter of the outer sleeve 20. The outer wall of the lower half part of the foot pad 220 is provided with a plurality of anti-slip strips.
Referring to fig. 6 and 7, the tension ring 23 is fixedly sleeved on the rotating shaft 22 and is located between the friction pad 21 and the rotating shaft 22. The tension ring 23 is provided with two protrusions 230, both of which are in a slope shape, and the two protrusions are oppositely designed on the tension ring 23, that is, the top of one protrusion is close to the bottom of the other protrusion. The rotation shaft 22 is rotated to drive the tension ring 23, and the protrusions 230 press the friction pad 21 to move out of the opening, so as to tightly adhere to the inner wall of the supporting leg 11, thereby increasing the friction force. The pad body 210 is designed such that one end thereof has a thickness greater than that of the other end thereof, mainly to fit the design of the slope of the protrusions 230.
The two connecting rods 12 of the frame body 1 are respectively connected between the outer sleeves 20, and certainly can be connected between the supporting feet 11, but are connected between the outer sleeves 20, so that the advantages of limiting the synchronous rotation of the outer sleeves 20 when the rotating shaft 22 is rotated can be achieved, and the length of the extension and the shortening of the two telescopic rod assemblies can be kept consistent.
As shown in the figure, when the telescopic rod assembly 2 is used, the rotating shaft 22 is rotated counterclockwise, the two protrusions 230 of the tension ring 23 respectively rotate to the inner sides of the two belt bodies 211, and after the rotating shaft is contacted with the thick end of the pad body 210, the rotating shaft is limited to continue rotating, and the friction pad 21 is not pushed outwards, so that the friction force between the friction pad and the supporting foot 11 is small, and the telescopic rod assembly 2 can freely extend and retract in the supporting foot 11 to adjust the height. When the height is adjusted to a proper value, the rotating shaft 22 is rotated clockwise, the two protrusions 230 of the tension ring 23 move towards the two pad bodies 210, the friction pads 21 are pushed outwards, the friction force between the friction pads and the supporting legs 11 is gradually increased, and the telescopic rod assembly 2 is locked.
