Abstract
The invention discloses a support leg structure of a movable stand in the field of movable stands for watching competitive sports matches; a support leg profile is fixedly arranged at the bottom of the support vertical column of every layer of stand; a pulley is movably arranged in each support leg profile; one side of each support leg profile is provided with a guide clamping side which is protruded outwards, and the other side of each support leg profile is provided with a guide groove; and in addition, in the two adjacent layers of stands, the guide clamping side on the support leg profile of one layer of stand extends into the guide groove on the support leg profile of the adjacent other layer of stand. In the support leg structure of the movable stand in the structure, when all layers of stands are stretched and slide, the stands can be freely stretched and does not deviate.
Description
Technical field
The present invention relates to watch the movable stand supporting foot structure in the movable stand of athletics sports match usefulness.
Background technology
Movable stand is widely used in all kinds of stadiums; Movable stand is made up of the grandstand that several layers can be stretched, contract usually, and the structural similarity of each layer grandstand includes deck plate; Deck plate is fixedly mounted on some girders; Girder is fixed on the support post, and the support post bottom all is equipped with the pulley that can roll on the ground, and support post and bottom pulley thereof constitute the supporting foot structure of movable stand.
The movable stand supporting foot structure is supporting each layer movable stand, and it is determining directly whether grandstand moves freely in the slides in telescopic process, smooth and easy.
Movable stand supporting foot structure commonly used at present; Referring to shown in Figure 1; With three layers of movable stand is example, and the supporting foot structure of the 3rd layer of grandstand comprises support post 1, and the top of support post 1 is set with girder 2; The bottom of support post 1 is set with sliding sleeve 3, is movably set with pulley 4 in the sliding sleeve 3; The supporting foot structure of second layer grandstand comprises support post 11, and the top of support post 11 is set with girder 21, and the bottom of support post 11 is set with sliding sleeve 31, is movably set with pulley 41 in the sliding sleeve 31; The supporting foot structure of first floor grandstand comprises support post 12, and the top of support post 12 is set with girder 22, and the bottom of support post 12 is set with sliding sleeve 32, is movably set with pulley 42 in the sliding sleeve 32.
The shortcoming that the movable stand supporting foot structure of said structure exists is: each layer grandstand is in the process of slides in telescopic, and pulley 4, pulley 41, pulley 42 slide separately separately, do not pin down each other, thereby easy sideslip, make movable stand stuck phenomenon occur.
Summary of the invention
The technical problem that the present invention will solve is: provide a kind of each layer grandstand can be freely, flexible movable stand supporting foot structure swimmingly.
For addressing the above problem; The technical scheme that the present invention adopts is: the movable stand supporting foot structure; Be characterized in: the bottom at the support post of each layer grandstand all is set with the leg section bar; Be movably set with pulley in the leg section bar, a side of described leg section bar is provided with the guiding edge of outside protrusion, and the opposite side of leg section bar is provided with direction recess; And in the adjacent two layers grandstand, the guiding edge on the leg section bar of one deck grandstand extend in the direction recess on next-door neighbour's the leg section bar of another layer grandstand.
The invention has the beneficial effects as follows: each layer grandstand is in the process of slides in telescopic, and the leg section bar of support post bottom interconnects, thereby makes the pulley in the leg section bar pin down and form whole slip each other, guarantees that grandstand is capable of expansion and contraction, can sideslip.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is done further detailed explanation.
Fig. 1 is the backsight structural representation of the movable stand supporting foot structure described in the background technology.
Fig. 2 is the backsight structural representation of movable stand supporting foot structure of the present invention.
The specific embodiment
Referring to shown in Figure 2; Movable stand supporting foot structure of the present invention---be example with three layers of movable stand in the present embodiment, the supporting foot structure of the 3rd layer of grandstand comprises support post 1, and the top of support post 1 is set with girder 2; The bottom of support post 1 is set with leg section bar 5; One side of leg section bar 5 is provided with the guiding edge 6 of outside protrusion, and the opposite side of leg section bar 5 is provided with direction recess 7, is movably set with pulley 4 in the leg section bar 5; The supporting foot structure of second layer grandstand comprises support post 11; The top of support post 11 is set with girder 21; The bottom of support post 11 is set with leg section bar 51, and a side of leg section bar 51 is provided with the guiding edge 61 of outside protrusion, and guiding edge 61 is inserted in the direction recess 7; The opposite side of leg section bar 51 is provided with direction recess 71, is movably set with pulley 41 in the leg section bar 51; The supporting foot structure of first floor grandstand comprises support post 12; The top of support post 12 is set with girder 22; The bottom of support post 12 is set with leg section bar 52, and a side of leg section bar 52 is provided with the guiding edge 62 of outside protrusion, and guiding edge 62 is inserted in the direction recess 71; The opposite side of leg section bar 52 is provided with direction recess 72, is movably set with pulley 42 in the leg section bar 52.
The movable stand supporting foot structure of said structure; Each layer grandstand is in the process of slides in telescopic; The movable each other overlap joint of the leg section bar 52 of the leg section bar 51 of the leg section bar 5 of support post 1 bottom, support post 11 bottoms, support post 12 bottoms and form an integral body; Thereby make pulley 4, the pulley 41 in the leg section bar 51 in the leg section bar 5, the pulley 42 in the leg section bar 52 pins down each other and form whole the slip, guarantees that grandstand is capable of expansion and contraction, can sideslip.
