Abstract
The utility model discloses a split type anti-collapse stage which comprises a stage plate and supporting legs hinged to the lower end of the stage plate. A circle of rack is fixed at the periphery of the lower end of the stage plate, and blocking parts are arranged at the backs of the supporting legs. When the supporting legs erect, the upper ends of the blocking parts abut against the lower end of the rack. The number of the supporting legs is four, and the supporting legs are symmetrically arranged on the left portion and the right portion of the stage plate. When the stage is folded, the supporting legs on the left portion and the right portion of the stage plate are oppositely folded to the middle of the stage plate, and meanwhile the two supporting legs folded in the same direction are connected through a horizontal rod. The split type anti-collapse stage is simple in structure and convenient to construct and dismount. When the stage is folded, the supporting legs can be fixed conveniently. When the stage is unfolded, the supporting legs are effectively prevented from turning outwards to enable the stage to collapse. Furthermore, the split type anti-collapse stage is convenient to store and transport.
Description
Technical field
The utility model relates to a kind of stage, is specifically related to a kind of anti-down stage of opposite opened of being convenient to build with folding.
Background technology
Along with people's living standard improve constantly, entertainment program is also more and more abundanter, especially out of doors the activity that public place is held is more and more, it is necessary as performance, setting up a platform, at present, the stage adopting on market is roughly divided into fixed and portable two kinds, the fixed place that takies, be only suitable for for regular performance occasion, and for the performance of going out a bit temporarily, as the performance of going and working in the countryside and mountainous areas, or small-scale tour etc. need portable stage, now generally all adopt plank and metal material to build temporarily, between metal material, adopt the mode of welding to fix, the a large amount of manpower and materials of process need, consuming time, material can not be reused, construction cost is high, and stage is generally the stand of first building bottom, and then spread table top, build and dismantle very trouble, and comparison spended time and manpower, and the structure of this kind of mode is very heavy, give transportation, dismounting and deposit and bring very large inconvenience, existing stage, some stage legs are fixed, be not easy to folding and deposit take up room greatly, what have is movable stage leg, the outside of stage leg is owing to there is no position-limit mechanism, at stage, launch, stage leg easily tilts or skews to stage outside, causing stage to collapse causes damage.
The shortcoming of prior art is: have the stage of movable stage leg, because stage leg outer side does not have position-limit mechanism, when stage launches, stage leg easily tilts or skews to stage outside, brings inconvenience and loses.
Utility model content
The purpose of this utility model is to provide a kind of anti-down stage of opposite opened that can prevent that stage leg from tilting or skewing to stage outside.
For achieving the above object, the technical solution of the utility model is as follows: the anti-down stage of a kind of opposite opened, comprise platen and the supporting leg hinged with platen lower end, described platen lower end surrounding is fixed with a circle stand, the back of described supporting leg is provided with block piece, when supporting leg is erect, described block piece upper end butt is lived stand lower end.
Adopt said structure, stand is fixedly connected with edge, platen bottom surface, supporting leg upper end and platen or stand are hinged, this stage structure is very simple, when setting up a platform, by a plurality of stage splicings, and when stage launches, supporting leg is erect, and by the block piece at the supporting leg back side, be connected to the lower end of stand, to supporting leg, carry out spacing, prevent that supporting leg from outwards turning down and making stage fall down to bring inconvenience and lose, can also play certain supporting role to stand simultaneously, this stage structure is simple, be convenient to mount and dismount folding, take up room little, be convenient to transportation and deposit.
Described supporting leg is four, and is arranged at symmetrically between two left part and the right part of platen, and when stage folding, the supporting leg of described platen left part and right part is relatively rolled over and turned over to platen middle part, and is connected with cross bar between two supporting legs of folding in the same way.
The design of employing opposite opened, facilitates the folding of supporting leg, takes up room little, and launches conveniently.
Described stand inner side is provided with U-shaped bearing, and the blind end of this U-shaped bearing is fixedly connected with stand inwall, and described supporting leg is connected with U-shaped bearing by shipping and reselling on another market, and the upper end of supporting leg has chamfering.
Supporting leg top is hinged with U-shaped bearing by shipping and reselling on another market, and while being convenient to supporting leg folding, towards platen middle part, overturns, and arranges when chamfering can be avoided supporting leg rotation folding and produces and interfere with platen bottom surface or U-shaped bearing.
The side of described U-shaped bearing is provided with pillar, and described supporting leg is provided with fixed bar, between described pillar and fixed bar, is provided with extension spring, one end of extension spring is fixed on pillar, the other end is fixed on fixed bar, and when stage folding, described extension spring is strained supporting leg by pillar.
Adopt said structure, the pillar of U-shaped bearing side is near the bottom surface of platen, during folding, the inner side of supporting leg is near the bottom surface of platen, fixed bar is near the outside of described supporting leg, extension spring and supporting leg are angled can better strain supporting leg, pillar also can be arranged on the middle part of U-shaped bearing side, as with the position such as coaxial of shipping and reselling on another market, extension spring can be parallel with supporting leg, while being convenient to stage folding, by extension spring, supporting leg is strained, prevent from rocking in process that supporting leg moves or transport at stage, bring inconvenience or lose.
Described U-shaped bearing lower end is concordant with stand lower end, after stage launches, supporting leg is vertical with platen, block piece is connected to the lower end of U-shaped bearing and stand, when stage folding, supporting leg and cross bar fall in the groove that stand surrounds, and the lateral surface of block piece is concordant with stand lower end, avoid between each stage, producing and interfering when transportation.
Described stand middle part is provided with the crossbeam that supports platen bottom surface.
Described stand and supporting leg are made by square tube.
The beneficial effects of the utility model are: structure is very simple, are convenient to building and dismantling of stage, fix supporting leg while being convenient to stage folding, when stage launches, effectively prevent that supporting leg from outwards overturning stage is toppled over, and deposits and convenient transportation.
