Description
Technical field
The utility model relates to a kind of booth case accessory, relates in particular to a kind of secondary protection device of air spring support booth case.
Background technology
Booth case is the device that various energy source interfaces are provided to exhibiter in each conference and exhibition center, generally all be built in floor, realize entering of circumscripted power line, in the time that booth case is carried out to built-in function, need to open case lid, and general case lid adopts very heavy iron piece, this needs a bracing or strutting arrangement to support after just making case lid open.
Air spring is existing more conventional booth case support member, after case lid is opened, the auxiliary case lid of top power of air spring is opened, after allowing case lid thoroughly open, air spring is in free state, and in air spring, protector snaps in slide bar automatically, thereby play a supporting role, once but in operating process the malfunctioning support force that loses of air spring, case lid is heavy closure under self gravitation effect, thereby injures operator.
For this situation, some users can place an iron block at the intersection of case lid and casing, once air spring is malfunctioning, the iron block that is stuck in hinged place plays certain position-limiting action, thereby prevent the heavy closure of case lid, but this measure needs the artificial iron block of placing, once forget or have potential safety hazard.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, the secondary protection device that provides a kind of air spring to support booth case, can after case lid is opened, automatically carry out air spring position spacing, thereby prevent malfunctioning rear the brought potential safety hazard of air spring.
For achieving the above object, the utility model proposes following technical scheme: a kind of air spring supports the secondary protection device of booth case, comprise casing, the case lid hinged with described casing side, support the air spring of described casing and case lid, described air spring has pressure cylinder and piston rod, described pressure cylinder end is by connector connect box, described piston rod end connects case lid lower surface by connector, also comprise bumper bar, described bumper bar has mutual vertically disposed swing arm and limiting plate, described swing arm end is provided with installing hole, described limiting plate is provided with spacing draw-in groove, described bumper bar is movably connected in air spring piston bar and described case lid junction by installing hole, described spacing draw-in groove is fastened on described piston rod.
Described spacing draw-in groove is Pear-Shaped, has the first draw-in groove and the second draw-in groove that are interconnected, and described the first draw-in groove is positioned at the second draw-in groove top.
Described the first draw-in groove diameter is greater than diameter of piston rod, is less than pressure cylinder diameter, and described the second draw-in groove diameter is greater than pressure cylinder diameter.
Described air spring is free type air spring.
Described pendulum arm length is consistent with air spring free state lower piston rod extension elongation.
Compared with prior art, the air spring that the utility model discloses supports the secondary protection device of booth case, by a bumper bar is installed on air spring, and be stuck on piston rod, once air spring is malfunctioning, when piston rod is retracted, the bumper bar being stuck on piston rod will stop piston rod to slide, thereby instead of piston bar is played a supporting role, and it is simple in structure, and security performance is high.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model air spring supports the secondary protection device of booth case;
Fig. 2 is the structural representation of the utility model bumper bar.
Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme of the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, a kind of air spring that the utility model discloses supports the secondary protection device of booth case, the potential safety hazard that the malfunctioning back box lid closure of main control air spring causes, specifically comprise casing 1, the case lid 2 hinged with described casing 1 side, the air spring 3 that supports described casing 1 and case lid 2, is movably connected in the bumper bar 4 on described air spring 3.
Particularly, described air spring 3 is free type air spring, has pressure cylinder 5 and piston rod 6, and described pressure cylinder 5 ends are flexibly connected with casing 1 sidewall by connector, and described piston rod 6 ends are flexibly connected with described case lid 2 lower surfaces by connector.
As shown in Figure 2, described bumper bar 4 has mutual vertically disposed swing arm 7 and limiting plate 8, described swing arm 7 length are consistent with air spring 3 free state lower piston rod 6 extension elongations, and described swing arm 7 ends are provided with installing hole 9, described bumper bar 4 is movably connected in the junction of piston rod 6 and case lid 2 by installing hole 9, described limiting plate 8 is provided with the spacing draw-in groove of Pear-Shaped, described spacing draw-in groove has upper end the first draw-in groove 10 and lower end the second draw-in groove 11 that are interconnected, described the first draw-in groove 10 diameters are greater than piston rod 6 diameters, be less than pressure cylinder 5 diameters, described the second draw-in groove 11 diameters are greater than described pressure cylinder 5 diameters.
A kind of air spring that the utility model discloses supports the secondary protection device of booth case, its operation principle is: open case lid 2, the auxiliary case lid 2 of top power of air spring 3 is opened completely, now air spring 3 plays a supportive role to case lid 2 in free state, piston rod 6 drives bumper bar 4 to slide along pressure cylinder 5 outer surfaces in stretching out, when piston rod 6 stretches out completely, bumper bar 4 landings are to piston rod 6 surfaces, now piston rod 6 is stuck in the first draw-in groove 10, once air spring 3 is malfunctioning, piston rod 6 is retracted, but now bumper bar 4 is blocked in pressure cylinder 5 ends, stop piston rod 6 to be retracted, now bumper bar 4 instead of piston bars 6 are played a supporting role, thereby avoid case lid 2 closures.
In the time of the closed case lid 2 of needs, manually provoke bumper bar 4, press down case lid 2 bumper bar 4 second draw-in grooves 11 are slided along pressure cylinder 5, thereby it is closed smoothly to realize case lid 2.
Technology contents of the present utility model and technical characterictic have disclosed as above; but those of ordinary skill in the art still may be based on teaching of the present utility model and announcements and are done all replacement and modifications that does not deviate from the utility model spirit; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present utility model and modifications, and contained by present patent application claim.
