Poster is perhaps when picture or when repairing to billboard, and staff must climb to could be to advertisement at the top of column
Board carry out repair and replacement, not enough safety and conveniently.
To solve this problem, has the billboard for having elevating function currently on the market.Although this billboard-like can
The lifting of billboard is realized using elevating mechanism, but its structure is mostly complex, is not easy to subsequent maintenance work.
Utility model content
One of the purpose of this utility model is to provide that a kind of structure is simple, works convenient for follow-up maintenance and has lifting function
The billboard of energy.
To achieve the above object, the utility model embodiment provides following technical solution:
Billboard with elevating function, including pedestal and billboard main body, the inner cavity of inside one of pedestal, inner cavity it
In be equipped with servo motor, the output end of servo motor is connected with worm screw by shaft coupling, and the two sides of pedestal are equipped with two and pass through extensively
Board main body and the slide bar that is slidably connected with it are accused, nut is equipped on billboard main body, is equipped with screw rod, screw rod and nut in nut
It is threadedly coupled, a worm gear engaged with worm screw is equipped on screw rod, end is rotationally connected on pedestal.
Preferably, nut is set at the back center of billboard main body.
Preferably, the upper end of screw rod is equipped with upper limit, and lower end is equipped with lower limit at worm gear.
Preferably, the side of pedestal is equipped with the button for controlling servo motor positive and negative rotation.
Due to the adoption of the above technical scheme, compared with prior art, there is the utility model the billboard of elevating function to have
It is standby following the utility model has the advantages that
It can be realized the positive and negative rotation of screw rod by control servo motor, worm screw and worm gear, and due to screw rod and nut spiral shell
Line connection, billboard main body connect with sliding bar, so when the positive and negative rotation for working as screw rod, billboard main body can therewith on move down
It is dynamic, that is to say, that by controlling servo motor, to can be realized the lifting of billboard.
The utility model is whole only to be increased by the i.e. controllable billboard of servo motor, worm screw, worm gear, screw rod and nut
It reduces, overall structure is simple, is convenient for subsequent maintenance work.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clear, complete description.Obviously, described embodiment is only the utility model a part of the embodiment, and not all embodiments.
Based on the embodiments of the present invention, those of ordinary skill in the art obtain all without making creative work
Other embodiments belong to the protection scope of the utility model.
Referring to Fig.1, with the billboard of elevating function, including pedestal 1 and billboard main body 2, the inside of pedestal 1 one
Inner cavity 3, is equipped with servo motor 4 among inner cavity 3, and the output end of servo motor 4 is connected with worm screw 5 by shaft coupling, and the two of pedestal 1
Side is equipped with two slide bars 6 for passing through billboard main body 2 and being slidably connected with it, is equipped with nut 7, nut 7 on billboard main body 1
In be equipped with screw rod 8, screw rod 8 is threadedly coupled with nut 7, equipped with a worm gear 9 engaged with worm screw 5, end turn on screw rod 8
It is dynamic to be connected on pedestal 1.
The size of inner cavity 3 is set according to servo motor 4, worm screw 5 and the occupied space of worm gear 9.It deposits inner cavity 3
A possibility that servo motor 4, worm screw 5 and worm gear 9 capable of being effectively protected, reducing raindrop erosion and get rusty,
It prolongs its service life.Screw rod 8 passes through the center of worm gear 9, and is fixedly connected with worm gear 9.The position of worm gear 9 should be in screw rod 8
Lower end, with worm screw 5 formed engage connection relationship.To facilitate installation, inner cavity 3 can also be not provided with, and servo motor 4 is pacified
Mounted in the upper surface of pedestal 1.
Nut 7 is mountable at the rear surface center of billboard main body 2, so that the lifting of billboard main body 2 is more stable.
When needing replacing the propagating poster in billboard main body 2, or repair cleaning to billboard main body 2,
The positive and negative rotation for controlling servo motor 4, may be implemented the elevating function of billboard main body 2.For this purpose, can pacify in the side of pedestal 1
Fill two buttons 10 for being used to control 4 positive and negative rotation of servo motor.
Servo motor 4 is connected with PLC control system, using button 10, can accurately adjust the height of billboard main body 2
Degree.In the case where not needing accurately to adjust the height of billboard main body 2, replace servo motor 4 with threephase asynchronous machine, equally
The elevating function of billboard main body 2 may be implemented.
One upper limit 11 is installed in the upper end of screw rod 8, a lower limit 12 is installed in lower end again at worm gear 9, so
Upper limit 11 and lower limit 12 and PLC control system are electrically connected afterwards.It is wide that upper limit 11 and lower limit 12 are respectively used to detection
Upper limit position when board main body 2 is gone up and down and lower position are accused, when PLC control system receives upper limit 11 or lower limit 12
When the electric signal transmitted, stop the rotation of servo motor 4, so that billboard main body 2 is avoided to rise too high and be detached from screw rod 8, or
Person's decline is too low and collides with pedestal 1.
The above is all the preferred embodiment of the utility model, and the protection scope of the utility model is not limited to above-mentioned
Embodiment, other technologies scheme belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, under the premise of no disengaging the utility model principle, several improvements and modifications that those of ordinary skill in the art are made, this
A little improvements and modifications, also should be regarded as the protection scope of the utility model.
