Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1: a kneeling crutch as shown in figure 1 and figure 2 is specially used for the patient with foot sprain. The crutch mainly comprises a supporting rod, an arc limiting plate 7, a knee-fitting groove body 9, a knee-protecting belt 12 and the like. The bottom of the supporting rod is connected with the four-corner supporting frame 1 through a fixing nut so as to improve the ground gripping capability and stability.

The structure of the arc limiting plate 7 is as shown in fig. 6 and 7, the front surface of the arc limiting plate is of a structure like a Chinese character 'shan', and a positioning shaft hole is arranged at the bottom position of the middle part of the arc limiting plate. The middle part of the middle convex plate is upwards provided with a middle convex plate 71, the center of the middle convex plate is provided with a movable shaft hole, and two sides of the middle convex plate are symmetrically provided with edge convex plates 72.

As shown in fig. 5, a top shaft hole is arranged at the top of the support rod and is provided with a lock shaft 6, and a fixed shaft hole of the arc-shaped limit plate 7 is sleeved on the lock shaft and is locked by the lock shaft.

As shown in fig. 3 and 4, the upper side of the knee-fitting groove body 9 is provided with a groove matched and fitted with the knee part of a human body, and knee-protecting belts 12 are fixed on two sides of the groove. The lower side of the knee-fitting groove body is provided with a parallel plate support 23 which is four parallel plates, the parallel plate support is provided with a shaft hole, and the shaft hole and a moving shaft hole 81 of the arc limiting plate are hinged to the composite hinged shaft 8 at the same time. The wearing comfort level can be improved after the flexible cushion layer is sleeved in the groove of the knee-fitting groove body 9.

The number of the arc limiting plates adopted in the embodiment is three, as shown in fig. 5, and a fit clearance exists between adjacent arc limiting plates. The three arc limiting plates and the four parallel plate supports are mutually sleeved and then provided with the composite articulated shaft. Therefore, the lock shaft can lock the arc limiting plate at any swinging angle, such as two angles shown in fig. 1 and fig. 2, and the angle shown in fig. 2 is generally the most common angle. The composite articulated shaft is a component which allows the knee-clinging groove body to swing back and forth on the arc limiting plate, and the range of the back and forth swing is limited by the edge convex plates at the two sides of the arc limiting plate, namely the back and forth swing range is limited and adjustable. The front and back swing is beneficial to the automatic drooping state of the supporting rod and the four-corner supporting frame below the supporting rod when the walking is carried out, and the walking is labor-saving and easy to carry out. The adopted structures of the plurality of arc limiting plates and the plurality of parallel plate supports can realize that the supporting rod does not swing left and right while swinging back and forth, and only allows the supporting rod to have the function of swinging back and forth.

In addition, a telescopic gasket 74 is sleeved in a fit clearance of the convex plates at the two sides, a strip-shaped hole 75 is formed in the telescopic gasket, a round hole is formed in the convex plate at the side, and a bolt penetrates through the round hole and the strip-shaped hole and is fixed by a nut. Therefore, the height of the telescopic gasket can be adjusted to adjust the swing range of the supporting rod in a sagging state.

When the vertical manual telescopic rod 4 is adopted, the vertical manual telescopic rod comprises an outer sleeve 41 and an inner sleeve 41 which are matched and sleeved and then locked through adjusting a locking wire, as shown in fig. 1. Wherein, the rotary stop block at the lower end of the mandril is sleeved in the cylindrical barrel 51 in a matching way and can rotate, but the annular stop table or the fixed cover can not axially slide when being stopped.

Example 2: on the basis of embodiment 1, a shock absorber is further arranged at the upper end of the supporting rod, the shock absorber shown in fig. 5 comprises a column casing fixedly connected with the supporting rod, a spring is sleeved in the column casing, the upper end of the column casing is provided with an opening, an annular baffle table is arranged at the edge of the opening or a fixed cover is arranged on the opening, a rotating stop block is sleeved in the column casing in a matching mode, the rotating stop block is upwards connected with a mandril, a fixed connecting plate is arranged at the upper end of the mandril, and the mandril hole is located in the middle of the fixed connecting.

Example 3: another kneeling crutch is used for assisting a patient with a foot sprain to walk and move, as shown in figures 8-13, the crutch comprises a vertical manual telescopic rod 4 with an adjusting lock wire 3 and a four-corner support frame 1, the bottom of the vertical manual telescopic rod 4 of the crutch is fixedly connected with the four-corner support frame 1 or a triangular support frame for enabling the patient to be firmer when using the kneeling crutch,

the top of vertical manual telescopic link 4 is equipped with lock axle 6, and arc limiting plate 72 has been worn on the top of vertical manual pole 4, and lock axle 6 passes the pole wall of vertical telescopic link 4 and the middle part of arc limiting plate 7 to perpendicular with arc limiting plate 7, lock axle 6 and vertical manual telescopic link 4 and arc limiting plate 7 are the standard and think X, Y, Z coordinate system form, and arc limiting plate 7 can rotate when lock axle 6 is not hard up, reaches the purpose of adjusting spacing angle.

One end of the lock shaft 6 is sleeved with a lock nut 10 and an anti-slip washer 11 matched with the lock nut 10, one side of the anti-slip washer 11 is provided with a clamping groove 18 for clamping and fixing the arc-shaped limiting plate 7, and when the lock nut 10 is locked, the lock shaft 6 cannot rotate; the top side of lock shaft 6 is connected with compound articulated shaft 8, and compound articulated shaft 8 top side closely is fixed with pastes knee cell body 9, makes and pastes knee cell body 9 and only can rotate around 8 through compound articulated shaft, avoids pasting the circumstances such as knee cell body 9 left right turn causes the focus unstability.

Certain gaps are respectively arranged between the two ends of the arc limiting plate 7 and the bottom side of the knee-clinging groove body 9, and the sum of the distance between the two ends of the arc limiting plate 7 and the bottom side of the knee-clinging groove body is smaller than 3cm, so that the knee-clinging groove body 9 has certain mobility and smaller amplitude, and the comfort level of people in walking is improved.

The locking shaft 6 is hinged with a knee-fitting groove body 9 through a composite hinged shaft 8, a knee protection belt 12 is arranged inside the knee-fitting groove body 9, connecting seats 14 used for fixing the knee and the lower leg of a patient are integrally arranged on two sides of the knee protection belt 12, a flexible gasket 13 is filled inside the knee protection belt 12, and the flexible gasket 13 and the knee protection belt 12 are sewn and fixed.

The bottom of the vertical manual telescopic rod 4 is a screw rod, the external sleeve of the screw rod is provided with at least two fixing nuts 2, the four-corner support frame 1 is sleeved outside the manual telescopic rod 4 and is fixed through the two fixing nuts 2, and the kneeling crutch is assembled by disassembling and installing the fixing nuts when in use, so that the kneeling crutch is conveniently stored when not in use.

Be equipped with bumper shock absorber 5 between vertical manual telescopic link 4 and the lock axle 6, bumper shock absorber 5 suit is on the top of vertical manual telescopic link 4 to with the 4 inseparable welded fastening of vertical manual telescopic link, bumper shock absorber 5's inside is equipped with damping spring 15, damping spring 15's top is equipped with rotates dog 54, rotate dog 54 top side and the axle bed of lock axle 6 inseparable welded fastening, and bumper shock absorber 5's top is fixed with fixed cover 17 through the fixed screw.
