Due to three ball assemblies 3 and outer sleeve chute 101 and the restriction of inner sleeve chute 201, make the inner sleeve 2 cannot be real
Now circumferentially rotate, the motion of straight line pull can only be done.
The structural representation of the display lowering or hoisting gear that Fig. 4 provides for this utility model embodiment.
This display lowering or hoisting gear includes the side face spline slide rail described in preceding embodiment, and connects bottom outer sleeve 1
The base 5 connect, the head rotation assembly 7 being connected with inner sleeve 2 top, the display installing rack being connected with head rotation assembly 7
6。
Arrange an air spring in the inside of inner sleeve 2, the lower end of this air spring is connected with base 5, upper end and inner sleeve 2
Top connect.Air spring has the elastic curve of near-linear, is suitable as determining power element and uses, using the teaching of the invention it is possible to provide stable props up
Support.
In the present embodiment, also set up inside and outside sleeve connector 4 in the upper end of outer sleeve 1, for by outer sleeve 1 and inner sleeve
Linking together of cylinder 2 fastening.
Inside and outside sleeve connector 4 can use following version: is provided with through hole in the upper portion side wall position of outer sleeve 1,
And brake pad is set in this through hole so that it is medial surface can touch the sidewall of inner sleeve.It is provided with in the outside of brake pad
Two blind holes, for built-in stage clip.Inside and outside sleeve connector 4 is arranged on the tip exterior of described outer sleeve 1, by described brake pad
In being wrapped in stage clip, and by stage clip, brake pad is pressed on the lateral wall of inner sleeve.Lift at regulation inner sleeve 2
In high process, brake pad can be made to compress inner sleeve 2 all the time, make the bonding strength between inner sleeve 2 and outer sleeve 1 firm.
The another kind of version of inside and outside sleeve connector 4 is: use expansion link latch components and brake pad.Brake pad
Inner surface is used for the wall contacts with inner sleeve 2, and outer surface is not provided with blind hole.Expansion link latch components is set in brake pad
Outward, a fixture and the cam spanner hinged with this fixture are specifically included.Fixture is set in outside outer sleeve 1, will friction
In block is wrapped in.When cam spanner is in locking state, the jut of cam spanner withstands on the outer surface of brake pad, is pressed
Tight on inner sleeve 2;And when cam spanner is opened, its jut and brake pad depart from, make brake pad upspring, reduce brake pad
And the friction between inner sleeve, makes inner sleeve 2 to lift smoothly.
During use, according to the value of elastic of the weight configuration air spring of display to be carried.Display installing rack 6 is pacified
After dress display, the value of elastic that the weight of display provides with air spring is in poised state, therefore can pass through pull inner sleeve
The mode of cylinder 2, arbitrarily regulation highly makes display remain at stable state, it is achieved the height of display is satisfied to be used
Need.In the lifting process of inner sleeve 2, increase the company between outer sleeve 1 and inner sleeve 2 by inside and outside sleeve connector 4
Connect firmness.
