4, undamped regulatory function, cantilever positioning are inaccurate.
Utility model content
According to the above-mentioned deficiencies in the prior art, technical problem to be solved by the utility model is: providing one kind can make
Medical hoist tower cantilever high-mechanic, stability of rotation is smooth, the damping adjustable rotating joint of the rift-free band limit of accurate positioning.
The damping adjustable rotating joint of band limit described in the utility model, including rotation connection structure, rotation connection knot
Structure includes the L-shaped axle sleeve in section, and axle sleeve one end is provided inwardly with bushing collars, and rotation axis, the axle sleeve other end are equipped in axle sleeve
It is fixed with bearing plate, is equipped with axial bearing between the end face and bushing collars, bearing plate of rotation axis；Rotation connection structure
It is equipped with limiting device.
Rotation axis and axle sleeve can be connected respectively to other expansion structures or exchanging structure (such as cantilever and cantilever, cantilever
And functional column) on, it is used as a cradle head, two parts can be connected, realizes that two parts rotate between each other.Rotation axis
It being located in axle sleeve, two end faces are equipped with axial bearing and are compressed by bearing plate rotation axis up and down, and it is compact-sized, it may be implemented to turn
Moving axis rotates under high-mechanic, steady and smooth, meets certain load-bearing property；Limiting device can guarantee that rotation axis and axle sleeve exist
Rotation, avoids the pipeline being installed in cantilever and functional column from being threaded together in certain angle.
Preferably, the bearing plate, which is connected through a screw thread, is fixed on axle sleeve.
Preferably, the axial bearing is thrust roller bearing.
The limiting device includes the limit plate being fixed on axle sleeve or bearing plate, and the first limit is fixed on limit plate
Position screw, is fixed with the second stop screw in rotation axis, can phase when the first stop screw turns to together with the second stop screw
Hu Gan Wataru makes rotation axis and the mutual rotational angle of axle sleeve not exceed 360 °, pipeline is avoided to be threaded together.
The rotation connection structure is equipped with damping adjustment structure, and the damping adjustment structure includes damping ring, resistance
Buddhist nun's ring is circumferentially arranged between rotation axis side wall and axle sleeve along rotation axis, and damping adjustment structure further includes holding screw, clamp screw
Nail is in contact across axle sleeve with damping ring.By adjusting holding screw, thus change the pressure between holding screw and damping ring,
It realizes to damp between rotation axis and axle sleeve and adjust, when use can make cantilever positioning more accurate, and drift is avoided to rotate.
The damping ring is clamping cloth support ring, and the sliding surface between holding screw and rotation axis can be made to connect without metal
Touching, thus the damage of holding screw and rotation axis can be reduced, there is fabulous wearability and cushioning effect.
Possessed beneficial effect is the utility model compared with prior art:
The damping adjustable rotating joint of band limit described in the utility model, it is reasonable in design, it can be in medical hoist tower
This joint is set at each rotation connection, cantilever and cantilever, cantilever and suspender, cantilever and functional column etc. are connected, it is real
The function that existing rotary spacing, high-mechanic, damping are adjusted, allows medical hoist tower in the case where bearing heavy load, and stability of rotation is smooth, fixed
Position avoids the pipeline at rotation connection from being threaded together precisely without drift.

Specific embodiment
The utility model is described further below with reference to embodiment:
As shown in figures 1-4, the damping adjustable rotating joint of band limit described in the utility model, including rotation connection knot
Structure, rotation connection structure include the L-shaped axle sleeve 4 in section, and 4 one end of axle sleeve is provided inwardly with bushing collars 4.1, installation in axle sleeve 4
There is rotation axis 6,4 other end of axle sleeve, which is connected through a screw thread, is fixed with bearing plate 8, the end face of rotation axis 6 and bushing collars 4.1,
Axial bearing 9 is equipped between bearing plate 8, axial bearing 9 is thrust roller bearing.Rotation connection structure is equipped with limit dress
It sets, limiting device includes the limit plate 1 being fixed on axle sleeve 4, the first stop screw 5 is fixed on limit plate 1, in rotation axis 6
It is fixed with the second stop screw 7, it can Xiang Hu Gan Wataru when the first stop screw 5 turns to together with the second stop screw 7.Rotation connects
Binding structure is equipped with damping adjustment structure, and the damping adjustment structure includes damping ring 2, and damping ring 2 is clamping cloth support ring, folder
Cloth supports ring set in rotation axis 6, and is located between 6 side wall of rotation axis and axle sleeve 4, and damping adjustment structure further includes holding screw
3, holding screw 3 passes through axle sleeve 4 and is in contact with clamping cloth support ring.
Working principle of the utility model is:
It is (such as cantilever and cantilever, outstanding that rotation axis 6 and axle sleeve 4 can be connected respectively to other expansion structures or exchanging structure
Arm and functional column) on, it is used as a cradle head, two parts can be connected, realizes that two parts rotate between each other.Rotation
Axis 6 is located in axle sleeve 4, and about 6 two end faces of rotation axis are equipped with thrust roller bearing and are compressed by bearing plate 8, compact-sized,
Rotation axis 6 may be implemented to rotate under high-mechanic, steady and smooth meets certain load-bearing property；Limiting device can guarantee to turn
