Abstract
The invention discloses a device for limiting the extension of multi-layer movable stands for sports match, concert and other large-scale activities, which comprises: a plurality of layers of step-like telescopic movable stands; limiting clamping loops are respectively installed on posts at the rear side of each layer of the movable stand, and a travel control device fixedly interconnecting a plurality of limiting clamping loops is arranged. According to the movable stands with the above structure, inserted pins are inserted into the limiting clamping loop on the post at the rear side of the layer of the movable stand without being extended and into a corresponding inserted pin hole of a travel control rod in order to fix the limiting clamping loop and the travel control rod, thus the movable stand without being extended is fixedly connected with the last layer of the movable stand; and the extension of the other layers of the movable stands is then performed, so as to guarantee that the needed stands are extended as required in the aspect of layer, and meet the using demand.
Description
Technical field
The present invention relates to the employed multilayer movable stands of large-scale activity such as a kind of sports tournament, concert.
Background technology
At present used multilayer movable stand comprises: the stepped Telescopic stadium of some layers, the stability of whole movable stand when guaranteeing to use is fixed the fixed buildings such as the column of final layer movable stand rear side and wall usually.The multilayer movable stand using method is: when needing each layer movable stand pulled out, for spectators; Again each layer grandstand retracted layer by layer after being finished, until be retracted in the top grandstand, can save using area like this, be convenient to transportation.Owing to be subject to the restriction in place, stretching of movable stand is also more and more frequent, some occasion may not need or can not stretch out all each layer movable stands fully because the place is little, for example limit two layers that only need stretch out in five layers of grandstand because of the place, this moment is owing to be subject to ground injustice, sideslip, skid and the impact of some artificial misoperations, following situation may appear: the one, two layers of required grandstand are pulled out fully, and satisfied instructions for use; The 2nd, pulled out one deck grandstand fully---such as the first floor grandstand, but with other layer grandstand---respectively pulled out half such as second, third layer grandstand, required grandstand namely occurred and stretched out incomplete situation, thereby affected result of use.As seen the movable stand of the above-mentioned traditional structure grandstand number of plies that often can occur stretching out does not reach the situation of needed row, is difficult to during use control exactly and stretches out the number of plies, affects result of use.
Summary of the invention
For addressing the above problem, the invention provides and a kind ofly can accurately control the device for limiting extension of multi-layer movable stands that movable stand stretches out the number of plies.
For addressing the above problem, the technical solution used in the present invention is: device for limiting extension of multi-layer movable stands, comprise: the stepped Telescopic stadium of some layers, column at every layer of movable stand rear side is separately installed with spacing clip, also is provided with the travel control device that a plurality of spacing clips can be interconnected and fixed.
A kind of improvement of the present invention, described travel control device comprises the Stroke Control bar, is respectively arranged with the pin hole that cooperatively interacts on Stroke Control bar and the spacing clip, latch can insert in the pin hole.
The another kind of improvement of the present invention, the cross section of the described spacing clip shape that takes the shape of the letter U, two sides relative at the spacing clip of U-shaped are respectively arranged with pin hole.
Advantage of the present invention is: during operation, on the column of that layer movable stand rear side that does not need to stretch out, in spacing clip and the corresponding pin hole of Stroke Control bar on the latch insertion column, fix spacing clip and Stroke Control bar, these movable stands that do not need to stretch out are fixedly connected with last one deck movable stand; And then carry out the operation of stretching out of other layer movable stand, thereby guarantee that required grandstand can reach needed row, satisfies instructions for use.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Fig. 1 is the backsight structural representation of multilayer movable stand of the present invention.
Fig. 2 is the sectional structure schematic diagram that does not stretch out along the multilayer movable stand of A-A line shown in Figure 1.
Fig. 3 is the sectional structure schematic diagram that stretches out along the multilayer movable stand of A-A line shown in Figure 1.
Fig. 4 is spacing clip shown in Figure 1 and the fixing detail drawing of Stroke Control bar.
The specific embodiment
Referring to Fig. 1, Fig. 2, shown in Figure 3, device for limiting extension of multi-layer movable stands of the present invention, comprise: the stepped Telescopic stadium of some layers---adopt five layers of stepped Telescopic stadium 1 in the present embodiment, movable stand 2, movable stand 3, movable stand 4, movable stand 5 is equipped with spacing clip 31 at the column 11 of movable stand 1 rear side, column 22 at movable stand 2 rear sides is equipped with spacing clip 42, column 33 at movable stand 3 rear sides is equipped with spacing clip 53, column 44 at movable stand 4 rear sides is equipped with spacing clip 64, column 55 at movable stand 5 rear sides is equipped with spacing clip 75; Spacing clip 31 in the present embodiment, 42,53,64,75 the cross section shape that takes the shape of the letter U, two sides relative at the spacing clip of U-shaped are respectively arranged with pin hole; Also being provided with can be with spacing clip 31,42,53,64,75 travel control device that are interconnected and fixed.Described travel control device comprises Stroke Control bar 6, be respectively arranged with the pin hole that cooperatively interacts on Stroke Control bar 6 and the spacing clip 31,42,53,64,75, latch 21 can insert Stroke Control bar 6 and spacing clip 31, latch 32 can insert Stroke Control bar 6 and spacing clip 42, latch 43 can insert Stroke Control bar 6 and spacing clip 53, latch 54 can insert Stroke Control bar 6 and spacing clip 64, latch 65 can insert in Stroke Control bar 6 and spacing clip 75 pin holes; For guaranteeing the stability of whole movable stand, the same with conventional method in the use, the column 11 of movable stand 1 rear side is fixing with wall 7.During normal the use, five layers of movable stand are pulled out layer by layer, for spectators; Again each layer grandstand retracted layer by layer after being finished, get final product until be retracted in the top grandstand.
In actual use, when running into because limiting two layers that only need stretch out in five layers of grandstand in the place---as only stretching out the 4th, during the 5th layer of movable stand, then: respectively with in the corresponding pin hole on the spacing clip 31 on the latch 21 insertion columns 11 and the Stroke Control bar 6, in corresponding pin hole on the spacing clip 42 on the latch 32 insertion columns 22 and the Stroke Control bar 6, in corresponding pin hole on the spacing clip 53 on the latch 43 insertion columns 33 and the Stroke Control bar 6, make spacing clip 31,42,53 and Stroke Control bar 6 be fixed together, referring to shown in Figure 4, namely with movable stand 1, movable stand 2 is fixedly connected with movable stand 3; And then carry out the operation of stretching out of movable stand 4, movable stand 5, like this, because movable stand 1 and fixed buildings wall 7 are fixed together, thereby can guarantee that required grandstand can reach needed row, satisfies instructions for use.
