Description
Technical field
The utility model belongs to the lamp box technical field, is specifically related to a kind of transparent panel closing device of lamp box.
Background technology
In the prior art, lamp box is owing to need to change, keep in repair or clean luminous light pipe, softbox, reflector or the picture etc. of its inside, and the transparent panel of the box body surface that all needs usually to turn on the light is installed, changed, operation such as cleaning.At present, lamp box especially its transparent panel weight of lamp box for large-scale outdoor advertising lamp box or subway exhibition room district is bigger, usually in order to be easy to open the transparent panel of lamp box, general all is at the dual-side of casing hydraulic jack to be installed, the other end of hydraulic jack expansion link is used for fixing the inside edge at transparent panel, be used to open transparent panel, when transparent panel opens to certain angle, by a hook that is installed in the casing dual-side transparent panel is hooked, prevent the transparent panel downward motion and influence the replacing of people each parts of lamp box inside, work such as maintenance or cleaning, because what use is hook, need the artificial operation of going, use very inconvenience, bring the potential safety hazard that crushes the people but also exist because of articulating error.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of transparent panel closing device of lamp box is provided, this closing device can open easily transparent panel and when transparent panel opens to certain proper angle position self-locking transparent panel is supported, installation, maintenance, replacing or cleaning to the luminous light pipe of box house, softbox, reflector, picture provide greatly convenient, and be practical and convenient reliable.
In order to realize above-mentioned technical purpose, the utility model is realized by following technical scheme:
The transparent panel closing device of a kind of lamp box described in the utility model, comprise the hydraulic jack that is installed in the light box both sides, one end correspondence of the expansion link of described hydraulic jack is fixed on the inside edge of the transparent panel of lamp box, and being provided with between described light box and the transparent panel can self-locking and be used to support the folding support bar of transparent panel.
As the further improvement of above-mentioned technology, described folding support bar is middle two connecting rods that hinged support is arranged, and the end of described head rod is fixed on the side of casing, and the end of second connecting rod is fixed on place, transparent panel inside edge.
In the utility model, clamping block that can self-locking when described second connecting rod is provided with head rod and second connecting rod and is launched into straight line, promptly when folding support bar is launched into straight line fully, should can not fold by folding support bar to opposite direction, guaranteed that when transparent panel opens to certain angle state it can be lived the transparent panel fixed support.
In the utility model, for the more convenient transparent panel of opening, described hydraulic jack is two, and it is separately fixed at the medium position of casing dual-side.Corresponding with it, described folding support bar is two pairs, the top position that is arranged on hydraulic jack that it is corresponding respectively.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model is owing to be equipped with the folding support bar with auto-lock function between light box and transparent panel, when transparent panel opens to certain position, folding support bar is in line and self-locking, thereby transparent panel can be supported and be locked in this position, be convenient to work such as installation, replacing, maintenance or cleaning, also avoided in the prior art because of articulating the potential safety hazard that crushes the people that error brings to each parts of box house;
(2) in the utility model, when closing transparent panel, spur transparent panel downwards, the inside, both sides of the edge of casing is amounted to and be accommodated in to folding support bar automatically, do not influence the overall appearance of light box, and is practical.

The specific embodiment
As shown in Figure 1, lamp box comprises light box 10, and described light box 10 surfaces are transparent panel 20.
As shown in Figure 1 and Figure 2, the transparent panel closing device of lamp box, specifically comprise the hydraulic jack 1 that is installed in light box 10 dual-side medium positions respectively, one end correspondence of the expansion link 11 of described hydraulic jack 1 is fixed on the inside edge of the transparent panel 20 of lamp box, being provided with between described light box 10 and the transparent panel 20 can self-locking and be used to support the folding support bar 2 of transparent panel 20, usually, for easy to operate needs, described folding support bar 2 is installed in the top position of hydraulic jack 1.
In the utility model, as shown in Figure 3, Figure 4, described folding support bar 2 is middle two connecting rods that hinged support is arranged, and the end of described head rod 21 is fixed on the side of casing 10, and the end of second connecting rod 22 is fixed on place, transparent panel 20 inside edges and is used to support transparent panel 20; Clamping block 221 that can self-locking when in addition, described second connecting rod 22 is provided with head rod 21 and second connecting rod 22 and is launched into straight line.
The operation principle of the transparent panel closing device of the utility model lamp box is:
