Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1 to Fig. 6, the lowering or hoisting gear of the utility model liquid crystal display fixed base, comprise fixing frame 100 and lifting frame 110, but lifting frame 110 relative fixed framves 100 are done elevating movement, reversing frame 120 is installed on lifting frame 110, be fixed with the mounting plate 130 that display screen is installed on reversing frame 120, display screen is adjusted the visual angle by stirring reversing frame 120, is convenient to watching of people.
In the utility model, that mounting plate 130 adopts is photo frame type mounting plate (referring to Fig. 6), described photo frame type mounting plate is provided with the interpolation frame 131 of grafting display screen, make the framework suitable on the installation panel of display screen with interpolation frame 131, the installation panel of display screen is enclosed within on the interpolation frame 131 by framework, thereby make display screen be installed in mounting plate 130, make things convenient for the installation and removal of display screen with photo frame grafting form.
In the present embodiment, in lifting frame 110 lower ends fixed force spring 111 is installed, fixed force spring 111 external end head Connection Brackets 100 are when lifting frame 110 rises, because the elastic reaction of fixed force spring 111 can be upspring lifting frame 110 automatically.One active latch 113 is installed in the lower end of fixing frame 100, and circular arc chamfering (referring to Fig. 3 and Fig. 5) has been made in these active latch 113 upper-end surfaces, has made location hook 115 on the lower end surface, is convenient to the location crossbeam 112 that is installed on the lifting frame 110 suitable.The arc angling relative with circular arc chamfering made in these location crossbeam 112 lower end surfaces, when location crossbeam 112 descends, by the suitable of circular arc chamfering and arc angling is mutual extrusion (referring to Fig. 2), make location crossbeam 112 slip over location hook 115, location crossbeam 112 is linked up with mutually with location hook 115.In addition, make the location protruding hook 116 suitable in crossbeam 112 upper-end surfaces, location, increase the soundness of snap close, upspringing suddenly of lifting frame when avoiding release and the personnel that cause injure with location hook 115.
What deserves to be mentioned is, at the right-hand member of active latch 113 the spring (not shown) is installed, this spring one end top is at active latch 113, and its other end pushes up to fixing frame 100, makes mobile active latch 113 return to the origin-location according to the elasticity of spring.On active latch 113, be fixedly connected with a control knob 114, be used to control moving of active latch, play the purpose of release by pillar.In the present embodiment, active latch 113, location crossbeam 112 and control knob 114 constitute the positioning means of a snap close lifting frame 110, make lifting frame 110 snap closes by positioning means; Control knob 114 is arranged on fixing frame 100 bottoms, by pressing control knob 114 its drive pillar and active latch 113 is moved, thereby reaches the purpose of positioning means release; Under the effect of spring, make active latch 113 return to the origin-location then.
The utility model is when dispatching from the factory, the operator can press down lifting frame 110, when the location crossbeam 112 on the lifting frame 110 contacts with active latch 113 upper-end surfaces (as shown in Figures 2 and 3), owing to act on the active force extruding active latch 113 of deciding power crossbeam 112, simultaneously under the effect of circular arc chamfering and arc angling, active latch 112 is moved to the right, thereby make location crossbeam 112 slip over active latch 113; In addition, active latch 113 is because the effect of spring makes it return to the origin-location.At this moment, the operator can discharge lifting frame 110, because the effect of fixed force spring 111 is risen its lifting frame 110, thereby make location hook 115 snap close mutually on the protruding hook 116 in the location of deciding power crossbeam 112 and the active latch 113, lock lifting frame, the packing of can packing has reduced packaging volume and freight.
In use, press control knob 114, because the effect of fixed force spring 111 can make lifting frame 110 rise; The display screen adaptive with it is installed on mounting plate 130 then, can be used, easy for installation, time saving and energy saving.
The utility model is by installing the mounting plate 130 of phase box form, be convenient to the dismounting and the installation of display screen, convenient for users to use, and snap close and release positioning means easily has been installed, when having avoided unpacking, upspringing suddenly of lifting frame 110 makes its simple to operate, easy to use, beautiful shape.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
