Other examples can have different values.
The attached drawing of the utility model is all made of very simplified form and uses non-accurate ratio, only to it is convenient,
The purpose of the utility model embodiment is lucidly aided in illustrating, is not to limit the enforceable qualifications of the utility model.Appoint
What modification of structure, the change of proportionate relationship or adjustment of size, is not influencing the effect and institute that the utility model can be generated
Under the purpose that can reach, it should all fall in the range of the revealed technology contents of the utility model can be covered.And this practicality is new
Identical label appeared in type attached drawing represents identical feature or component, can be applied in different embodiments.
As shown in Figures 1 to 4, the utility model provides a kind of extrapolation chiasma type strut, including upper mounting and fixing support 11, under
Mounting and fixing support 12, upper strut 31, upper strut fixed plate 21, lower supporting rod 32, lower supporting rod fixed plate 22, sliding pin 4, upper strut part
Fixed seat 61, lower supporting rod part fixed seat 62.
Wherein, upper strut fixed plate 21 is bolted on mounting and fixing support 11, and lower supporting rod fixed plate 22 uses
Bolt is fixed on lower mounting and fixing support 12；The upper end of upper strut 31 is rotatablely connected with upper strut fixed plate 21, and upper strut 31
It can smoothly be rotated around the axis facade of upper strut fixed plate 21, the lower end of upper strut 31 is rotated with upper strut part fixed seat 61
Connection, and upper strut 31 also can smoothly surround the axis facade rotation of upper strut part fixed seat 61；The lower end of lower supporting rod 32
It is rotatablely connected with lower supporting rod fixed plate 22, and lower supporting rod 32 can smoothly be rotated around the axis facade of lower supporting rod fixed plate 22, under
The upper end of strut 32 is rotatablely connected with lower supporting rod part fixed seat 62, and lower supporting rod 32 also can smoothly surround lower supporting rod part
The axis facade of fixed seat 62 rotates.
Further, upper hopper chute 41 is offered in upper strut 31, and upper hopper chute button mouth 51 is equipped on the right side of the lower end of upper hopper chute 41；Under
Gliding groove 42 is offered in strut 32, and gliding groove button mouth 52 is equipped on the right side of the upper end of gliding groove 42；Sliding pin 4 passes through 41 He of upper hopper chute
Gliding groove 42, by 32 interconnection of upper strut 31 and lower supporting rod；Sliding pin 4 is equipped with adjustable nut, by adjusting the nut
Elastic sliding pin 4 can be enable swimmingly to be slided in upper hopper chute 41 or gliding groove 42；And upper hopper chute button mouth 51 and gliding groove
Button mouth 52 can limit sliding pin 4.
When chiasma type strut of extrapolating is opened, it is pulled outwardly by upper strut part fixed seat 61, lower supporting rod part fixed seat 62,
When forgetting about it a position, sliding pin 4 can be fallen into gliding groove button mouth 52, and entirely extrapolation chiasma type strut has a pause at this time, this
When as inwardly pushed, sliding pin 4 can first encounter the blocking position of gliding groove button mouth 52 so that it is not so easy inwardly to push.Outside
It when pushing away chiasma type strut and closing, then is drawn to external, sliding pin 4 leans against to be moved outwardly on 41 inner wall of upper hopper chute, is further accelerated at this time
Inwardly, sliding pin 4 can avoid the blocking of gliding groove button mouth 52 by mobile some distances on the arc of upper hopper chute button mouth 51, until to
Interior movement stops, and sliding pin 4 naturally falls in 42 bottom of gliding groove.
For example and without limitation, extrapolation chiasma type strut provided by the utility model can be adapted for some open airs by wall
The advertising lamp box of placement, large-scale mosaic display screen, monitoring center display screen etc..In the present embodiment, with chiasma type strut of extrapolating
Applied to being illustrated for LCD display, the back of the LCD display is provided with vertical installation card slot.
When installing LCD display using extrapolation chiasma type strut, first by the upper strut 31 for chiasma type strut of extrapolating and lower support
Bar 32 is stretched to defined position, and sliding pin 4 is made to fall into gliding groove button mouth 52, then by upper strut part fixed seat 61 and lower supporting rod zero
Part fixed seat 62 1 it is upper, one under, the two is slidably mounted on respectively in the back installation card slot of LCD display 7；Finally
The extrapolation chiasma type strut for being equipped with LCD display is fixed on wall by upper mounting and fixing support 11 and lower mounting and fixing support 12
It is upper.In a preferred embodiment, two groups of extrapolation chiasma type struts can be installed at display screen back.
When opening extrapolation chiasma type strut, LCD display 7 is pulled open to defined position, sliding pin 4 is fallen into gliding groove button mouth 52
(as shown in Figure 4), plays limit left and right while locked upper and lower strut ensures that mobile effect does not occur for LCD screen 7.At this point, extrapolation
Chiasma type strut can directly extrapolate display screen level a distance, convenient directly to be safeguarded to display screen back electrical part
It replaces, save space and uses manpower and material resources sparingly；In a preferred embodiment, extrapolation chiasma type strut extrapolates display screen level
500mm or so.
When closing extrapolation chiasma type strut, first pull-up LCD display outward so that sliding pin 4 enters in upper hopper chute button mouth 51,
It closes extrapolation chiasma type strut rapidly again, keeps the sliding in upper hopper chute 41 of sliding pin 4 a bit of and across gliding groove button mouth 52, finally
It carries out touching again and closes extrapolation chiasma type strut, after closing, sliding pin 4 naturally falls in 42 bottom of gliding groove, tightens cunning at this time
Nut on pin 4 makes sliding pin 4 fix.
Foregoing description is only the description to the utility model preferred embodiment, is not to any of the scope of the utility model
It limits.Any change or modify equal that any those skilled in the art makes according to the technology contents of the disclosure above
Equivalent effective embodiment is should be considered as, technical solutions of the utility model protection domain is belonged to.
