The utility model has advantages of simple structure, skill design, low production difficulty and production cost. the telescopic operations can be easily implemented, the movable baseboard for mounting an electric curtain wall can implement the vertical multiple-degrees swinging movement, and the utility model is convenient for using and operating.
Description
Technical field
The utility model relates to connection device, particularly a kind of can stretching and the telescopic boom of up-down adjustment movable floor.
Background technique
In the prior art, in industries such as advertisement, performance, often to make up large-scale electronics curtain wall, thereby make spectators can see the content that to show clearly clearly in indoor and outdoor.But these electronics curtain walls all are mounted in mostly and are fixedly coupled on the seat, thereby the angle of defining can not be rotated or moved, and the spectators that only can satisfy an orientation watch, can not adjust, also be inconvenient to cooperate different displaying contents to adjust the optimum position of electronics curtain wall simultaneously.Though some electronics curtain wall is mounted on some connecting bases that can rotate the activity of living in addition, these connecting base structures are generally all complicated, and difficulty of processing is big, the cost of production height, and also the precision of regulating is also not high enough.
The model utility content
The purpose of this utility model is, provide a kind of structural design ingenious, simple and reliable telescopic boom, this telescopic boom processing difficulty is low, and cost of production is low, can easily realize expanding-contracting action, and be used to install the movable floor swing of multi-angle up and down of electronics curtain wall.
The technological scheme that the utility model is adopted for achieving the above object is:
A kind of telescopic boom, it comprises two fixed bases that are set up in parallel, and is provided with a telescopic mobile body frame between described two fixed bases, this right-hand member that moves body frame can be swung is provided with a movable floor.
As further improvement of the utility model, described mobile body frame comprises a main framing, one movable skeleton, first stepper motor and second stepper motor, the two ends of described main framing are separately fixed at the top of two fixed bases, the top of described movable skeleton is provided with tooth bar, this movable skeleton slidably is arranged on the below of main framing, the left end of this movable skeleton is fixed with a movable block that is nested with on described main framing, the right-hand member of this movable skeleton slidably passes the fixed base that is positioned at the right side, described first stepper motor is fixed in the fixed base sidewall on right side, its output shaft stretches in this fixed base, this output shaft be provided with one with described tooth bar meshed gears, described second stepper motor is fixed on the right-hand member of described movable skeleton.
As further improvement of the utility model, described movable floor is hinged on the right-hand end of described movable skeleton, and both sides are fixed a transmission rope respectively up and down in this movable floor hinged place, and described two transmission ropes are fixed on the output shaft of described second stepper motor.
As further improvement of the utility model, be provided with rolling bearing in the described movable block, this rolling bearing is between this main framing and movable skeleton.
As further improvement of the utility model, be provided with rolling bearing in the fixed base on described right side, this rolling bearing is positioned at the below of movable skeleton.
As further improvement of the utility model, the bottom of described main framing and movable skeleton is provided with slide rail.
The beneficial effects of the utility model are: the utility model is simple in structure, designs ingeniously, and its production difficulty is low, cost of production is low, can realize expanding-contracting action easily, and the movable floor that is used to install the electronics curtain wall can be realized the swing of multi-angle up and down, operation easy to use.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a sectional view of the present utility model.
Embodiment
Embodiment: see Fig. 1 and Fig. 2, a kind of telescopic boom of the utility model, it comprises two fixed bases that are set up in parallel 1, is provided with a telescopic mobile body frame 2 between described two fixed bases 1, this right-hand member that moves body frame 2 can be swung is provided with a movable floor 3.
Described mobile body frame 2 comprises a main framing 21, one movable skeleton 22, first stepper motor 23 and second stepper motor 24, the two ends of described main framing 21 are separately fixed at the top of two fixed bases 1, the top of described movable skeleton 22 is provided with tooth bar 221, this movable skeleton 22 slidably is arranged on the below of main framing 21, the left end of this movable skeleton 22 is fixed with a movable block 222 that is nested with on described main framing 21, the right-hand member of this movable skeleton 22 slidably passes the fixed base 1 that is positioned at the right side, described first stepper motor 23 is fixed in fixed base 1 sidewall on right side, its output shaft stretches in this fixed base 1, this output shaft be provided with one with described tooth bar 221 meshed gears 223, described second stepper motor 24 is fixed on the right-hand member of described movable skeleton 22.
Described movable floor 3 is hinged on the right-hand end of described movable skeleton 22, and both sides are fixed a transmission rope 31 respectively up and down in these movable floor 3 hinged places, and described two transmission ropes 31 are fixed on the output shaft of described second stepper motor 24.Be provided with rolling bearing 25 in the described movable block 222, this rolling bearing 25 is between this main framing 21 and movable skeleton 22.Be provided with rolling bearing 25 in the fixed base 1 on described right side, this rolling bearing 25 is positioned at the below of movable skeleton 22.Described main framing 21 is provided with slide rail 26 with the bottom of movable skeleton 22.
Use the time of the present utility model, with two fixed base 1 horizontal fixed, first stepper motor, 23 forward or reverse, under the engagement of gear 223 and tooth bar 221, order about that movable skeleton 22 stretches out forward or withdrawal backward, second stepper motor, 24 forward or reverse, thus the transmission rope 31 of realization tension upside or downside is realized the angle adjustment that movable floor 3 swings up and down.The cooperation of movable block 222, bearing and slide rail 26 has reduced the frictional force between main framing 21, movable skeleton 22 and the base, has easily realized flexible function, has avoided bad phenomenon appearance such as noise free.
As described in the utility model embodiment, with other telescopic booms of the same or similar structure of the utility model, all in the utility model protection domain.
