Specific implementation mode
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
As shown in Figures 1 to 4, the damping structure of optical fiber splicer display screen component described in the utility model includes first
Connecting plate 3, the first sleeve 2, the second connecting plate 13 and second sleeve 8, the first connecting plate 3 connect with display screen component 23, also wrap
Include center-pole 5, bearing 6, screwed pipe 10, flow control valve 11, speed change bolt 4 and gear lever 7, the second connecting plate 13 and fused fiber splice
Owner's case 22 connects；Center-pole 5 is pivotally supported at by bearing 6 in the first sleeve 2 and second sleeve 8, the first sleeve 2
The ring set 2-1 that center-pole 5 rotates together can be driven by having on inner wall, and the lower end of center-pole 5 is involute spline, screwed pipe 10
Endoporus is the spline housing coordinated with involute spline, and is also provided on the endoporus of screwed pipe 10 and draws oil groove, the outer wall of screwed pipe 10 and
Two sleeves 8 are threadedly coupled, and form oil cylinder 12 between 10 lower end of screwed pipe and second sleeve 8, have hydraulic oil in oil cylinder；Gear lever 7
It is inserted in speed change bolt 4 in the centre bore of center-pole 5, the upper end of gear lever 7 is connect with speed change bolt 4, flow control valve 11
It is connect with screwed pipe 10.
There is store oil space between the upper end and the bottom surface of center-pole 5 of the flow control valve 11.
The lower end of the gear lever 7 is in up-small and down-big taper, and is pierced by from 5 lower end of center-pole, and flow control is then passed through
Valve 11 processed.
Since the lower end of gear lever 7 is in up-small and down-big taper, when adjusting speed change bolt, so that it may so that on gear lever 7
Lower movement makes the flow velocity for the liquid for flowing through the gap change to change the gap between gear lever 7 and flow control valve 11
Become, correspondingly can also adjust the speed of the movement of screwed pipe 10, then influences center-pole 5, the first sleeve 2 and the first connecting plate 3
Rotating speed, to adjust display screen component rotation speed.Thus the utility model is by using gear lever 7 and adjusting screw 4
The speed that display screen component rotation can be adjusted, to meet the needs of user.
As shown in figure 3, the cross section on 5 top of center-pole is the cylinder with vertical incision, and on 2 inner wall of the first sleeve
The centre bore of ring set 2-1 be the irregularly-shaped hole coordinated with 5 top of center-pole.Using this structure, the first sleeve 2 can be very
Easily center-pole 5 is driven to rotate, without reusing flat key etc., installation is very convenient.
As shown in Fig. 2, the top of the first sleeve 2 is fitted with dustproof cover 1.Dust, steam etc. can be prevented using dustproof cover 1
Into in the first sleeve 2, prevent internal parts from getting rusty, damaging.
The operation principle of the utility model is as follows：When decontroling display screen component 23, the first connecting plate 3 is with display screen component 23
It rotates together, the first connecting plate 3 drives the first sleeve 2 to rotate together, and the ring set 2-1 on 2 inner wall of the first sleeve drives central shaft 5
Rotate together, since the lower end of central shaft 5 is connect with screwed pipe 10 by involute spline, spline housing, screwed pipe 10 again with second set
Cylinder 8 is connected through a screw thread, and then screwed pipe 10 drives the stream for being secured to connection simultaneously along 5 slide downward of center-pole, screwed pipe 10
Control valve 11 moves down, and the hydraulic oil in the oil cylinder 12 that 10 lower end of screwed pipe is formed with second sleeve 8 is along gear lever 7 and stream
Gap between control valve 11 flows up, the store oil between the upper end of flow control valve 11 and the bottom surface of newel 5
Space, using the oil pocket for drawing oil groove and entering 10 top of screwed pipe on 10 endoporus of screwed pipe, due to gear lever 7 and flow control valve 11
Between gap very little, increase hydraulic oil toward resistance up, also slow down just the speed that screwed pipe 10 declines, while slowing down
The rotating speed of mandrel 5 influences the rotating speed of the first sleeve 2 and the first connecting plate 3 further through central shaft 5, to make display screen group
The spin down of part or stopping.And when lifting display screen component 23, the first connecting plate 3 and the first sleeve 2 are with display screen group
Part inverts, and the ring set 2-1 on 2 inner wall of the first sleeve drives center-pole 5 to invert together, and makes the screwed pipe being sleeved on center-pole 5 10
It up moves, draw oil groove of the fluid above screwed pipe 10 on 10 inner wall of screwed pipe moves down, and reaches the storage of 5 lower section of newel
Oily space, at this point, flow control valve 11 is opened, the fluid in store oil space enters spiral shell through the check valve 11-1 on flow control valve
The oil cylinder of 10 lower section of pipe, thus lift the resistance very little of display screen component.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
