Detailed Description

The utility model is further described below with reference to the accompanying drawings:

the lower limb height adjusting bracket in operation, as shown in figure 1, comprises

A base member 100 for connecting a fixing frame; and

a cross bar 300 having a cross bar adjusting part at one end and a limb fixing part 400 at the other end, the cross bar adjusting part having

The end 310 of the telescoping member is connected to,

a substrate connection end 320 rotatably connected to the substrate member 100; and

the extensible member 200 has one end rotatably connected to the support portion 110 of the base member 100 and the other end rotatably connected to the extensible member connection end 310.

The rotation of the cross bar 300 by means of the substrate connecting end 320 can be realized by the extension of the extensible member 200, so that the up-and-down movement of one end of the cross bar 300 far away from the cross bar adjusting part is realized, and the specific principle of the cross bar 300 is the same as the lever principle with that of fig. 3.

The cross bar adjusting part is provided to cross the body of the cross bar 300. In some embodiments, the center of the rail adjustment portion is connected to the rail 300 such that the upper end of the rail adjustment portion is tilted up with respect to the rail 300.

In another mode, as shown in fig. 5, the expansion piece connecting end 310 is further provided with an adjustable cross bar, and the adjustable cross bar is detachably provided with a limb fixing part 400, so that a bilateral use can be realized. Thereby being suitable for different use environments.

The lower end of the base plate member 100 is convex outwards towards the telescopic member side to form a bearing part 110; the expansion piece connecting end 310 at the upper end of the cross bar adjusting part is inclined to the expansion piece side. The expansion member side is referred to as the expansion member 200 based on the base member 100, and is located on the side of the base member 100 near the expansion member 200, and is not limited to have a connection relationship with the base member 100. Set up horizontal pole regulating part to the tilt state to the slope of extensible member 200 one side, make extensible member link 310 can be better with supporting portion 110 phase-match, both outwards bulge for base plate spare 100 main part, the better extensible member 200 of settling of being convenient for, make extensible member link 310, supporting portion 110 can be better keep in a vertical direction. And, after the telescopic member connecting end 310 at the upper end of the rail adjusting part is inclined, the telescopic member connecting end also forms an upwarping structure, so that the base plate part 100, the rail adjusting part and the telescopic member 200 form a structure similar to a bow. When the telescopic rod 200 drives the cross rod adjusting part to rotate, the cross rod adjusting part has a larger downward moving distance, and the height adjusting range is enlarged. And adopt this kind of telescopic link drive altitude mixture control, make its actuating mechanism deformation range little, stable in structure is reliable, easy observation maintenance.

The cross rod 300 is adjustable in length, the length can be adjusted randomly, and one mode of a specific limiting structure can refer to the prior art.

The telescoping member 200 is in some forms a motorized lift rod that can be adjusted for extension and retraction by a foot-operated control switch.

As shown in fig. 2, one end of the cross bar 300 away from the cross bar adjusting part is connected with the limb fixing part 400 through an angle adjusting part 330 and an angle adjusting part 420 of the limb fixing part 400.

The angle adjusting part 420 includes a plurality of fixing leaves forming a fixing chamber 421 therebetween, and the angle adjusting member 330 is disposed in the angle adjusting part 420.

Retaining member 430 passes through to be equipped with between arbitrary two fixed leaves, adjusts two fixed leaf intervals through retaining member 430. The inner diameter of the fixed cavity 421 is controlled to be reduced by adjusting the distance between the two fixed blades, so that the angle adjusting piece 330 is clamped, and the two fixed blades are fixed.

The angle adjusting member 330 is disposed at one side of the cross bar 300; the fixed cavity 421 has a ball head cavity therein; the angle adjusting member 330 has a ball joint at its end. Therefore, the limb fixing part 400 can rotate and swing for 360 degrees by taking the universal ball head as a rotation point, and the inclination angle of the limb fixing part 400 can be better adjusted.

The fixed cavity is a strip-shaped fixed cavity, and one end of the cavity of the angle adjusting member 330 is inserted into the fixed cavity 421; the angle-adjusting member 330 is perpendicular to the cross bar 300. This allows the limb fixing unit 400 to rotate with respect to the angle adjuster 330, and the angle adjuster 330 serves as a rotation shaft to rotate the limb fixing unit 400, thereby changing the angle of the limb fixing unit 400.

In other embodiments, it is within the scope of the present invention that the replacement angle adjustment member 330 is disposed on the limb fixing portion 400, and the angle adjustment portion 420 is disposed on the cross bar 300.

The limb fixing part 400 is provided with a U-shaped fixing piece 410; the base member 100 is provided with a fixing mechanism 500. The U-shaped fixing member 410 is used for placing the lower limbs of the human body.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the utility model. All falling within the scope of protection of the present invention. The protection scheme of the utility model is subject to the appended claims.
