Description
Technical field
This utility model relates to a kind of operating theatre equipment, particularly relates to a kind of scalable air spring arm.
Background technology
Tower crane, as one of basic medical device product, accounts in the medical device product such as orthopedics department, lucky section, surgery
There is very important status.The indispensable instrument during surgical is not only by tower crane, is also in patient's recovery process after surgery
Commonly used important tool.Along with the continuous progress of medical skill, kind and the function of tower crane are more and more abundanter.From base
This elevating function, extend to local elevation, rotate, suspend in midair, the function such as inclination, it is also possible to have more combination function, as needed
Can slide when wanting, it is not necessary to time can be fixed；Leg can be lifted when needing, it is not necessary to time leg can be set level
Etc., according to the function that different situation combinations is different.
Scalable air spring arm, as a part for tower crane, is mainly used in placing various armarium, such as illuminating lamp, extension
Hook, conduit etc..Spring arm is during rotating, moving up and down, and its workbench holding armarium must remain water
Flat, otherwise, equipment easy landing generation contingency.
Existing spring arm less stable, adjusts to suitable angle and is difficult to remain stable, over time for a long time
Passage, be often shifted over.Therefore, if ensureing that spring arm is in use stably maintained at a poised state and becomes
An important technological problems for field of medical device.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of novel adjustable solar term
Spring arm, its simple in construction, reliability is high, it is little to take up room.
This utility model be the technical scheme is that
A kind of novel scalable air spring arm, including parallelogram lindage, workbench and air spring, described parallel four-bar machine
Structure includes the arm body as the first fork, the second fork, connecting rod and pedestal, and workbench is fixed on connecting rod, and described connecting rod is
One flange, one end of described arm body is rotationally connected with pedestal, and the arm body other end is provided with cavity, the cavity of the arm body that flange is arranged
In, flange can rotate in the cavity of arm body, and the second fork and air spring are arranged in arm body, the one of described second fork
End is rotationally connected with flange, and the other end of the second fork is rotationally connected with pedestal, and one end of described air spring rotates even with pedestal
Connect, the tight pushing manipulation orchid rotating shaft of the air spring other end.
By such scheme, the other end of described air spring and the slide block close contact being arranged in arm body, the rotation of described flange
Being provided with eccentric pendulum in rotating shaft, the end of eccentric pendulum is provided with roller, roller and slide block close contact.
By such scheme, outside described flange rotating shaft, it is provided with operation arm.
This utility model has the beneficial effects that:
1, arranged by parallelogram lindage and realize workbench level all the time；
2, by the setting of air spring so that have an active force in flange rotating shaft all the time, it is ensured that there is no External Force Acting
Under, operating position does not changes, as long as giving the external force that handle is lighter, it is possible to realizing the movement of workbench easily, operation is just
Victory, reliable operation；
3, connecting rod being transformed to flange be arranged in arm body, on the one hand structure more steps up to promote, and on the other hand adds work
The born a heavy burden scope of platform, connecting rod will not deform.
4, by arranging eccentric balance wheel on flange, air spring, by slide block and eccentric balance wheel close contact, operates more flexible；
5, this patent structure tightly promotees, and takes up room little.
