Only extension rod 2 stretches out motion to being done outside fixed body 1.
Slided in fixed body 1 by extension rod 2 and realize Telescopic, maintaining body can keep the length after integral telescopic
Degree, it is to avoid it voluntarily extends under external force, and it can be jack, slot, or concave-convex fit structure to plug mechanism.
The maintaining body includes button 3 and return springs 4, and the mechanism side wall that plugs of the fixed body 1 is provided with footpath
To open slot, what button 3 can be slided is installed in the open slot on fixed body 1, and extension rod 2 is towards the sidewall surfaces of open slot one
Be provided with slide along direction arrangement unidirectional latch gear 5, button 3 towards plug mechanism's inner opposite end can with extension rod 2 on
Unidirectional latch gear 5 engage, return springs 4 can be provided and elastically keeping that unidirectional latch gear 5 is engaged to button 3
Power, the one-way movement of extension rod 2 is realized by unidirectional latch shelves, can only be shunk, it is impossible to stretch out, it is to avoid released by external force effect
Display, causes display to damage, it is necessary to when adjusting, depresses button 3 could realize that extension rod 2 extends, in addition to this kind of structure,
Can also be that slide construction fitted bolt holds out against detent mechanism to realize the real-time clamping to display, or realized by cylinder
Or realized by pinion and rack etc..
The button 3 is matched with the unidirectional latch tooth form on extension rod 2 towards plugging mechanism's inner opposite end surface and be provided with
The unidirectional latch 6 of button, the unidirectional latch 6 of button be able to be extend into the teeth groove of the unidirectional latch on extension rod 2, and button is unidirectional
Latch 6 is firm, stable when holding is engaged with the unidirectional latch on extension rod 2, and the structure is easy to behaviour using safety, simple structure
Make.
The button 3 is hinged on fixed body 1, and the one end of button 3 stretches out in the outer surface of fixed body 1, the opposite side of button 3
Fixed body 1 being extend into along open slot and plugging in mechanism engaged with the unidirectional latch gear 5 on extension rod 2, the sandwiched of return springs 4
Between the surface of fixed body 1 and the one end of button 3, the jointed shaft 7 that button 3 and fixed body 1 are hinged just is located between the two ends of button 3,
The positioning of button 3 is realized by way of being hinged, and forms lever construction, the one end of button 3 is acted on by the elastic force of return springs 4 begins
Eventually be in upwarp state, the other end of button 3 then all the time in extension rod 2 on the unidirectional engagement of latch gear 5, use
When, the one end of depresses button 3 declines it, and then the other end of button 3 is climbed away unidirectional latch gear 5, and then realizes extending
The pull elongation of bar 2, after regulation terminates, unclamps the one end of button 3, and the other end of button 3 is engaged with unidirectional latch gear 5 automatically, should
Simple structure, easy to operate, lever principle causes rapid operation, and button 3 straight up and down is can also be in addition, such as T-shaped button
3, it is plugged in-house motion towards fixed body 1 all the time by elastic component elastic force, by pulling button 3, it is also possible to realize
Above-mentioned functions, also or by setting inclined chute on fixed body 1, mechanism head are plugged by promoting button 3 along fixed body 1
The slip of degree direction realizes that the other end of button 3 is exited and plugs mechanism and depart from unidirectional latch gear 5.
