Description
Technical Field
The utility model relates to a screen drive arrangement opens and shuts belongs to display screen technical field.
Background
At present, the existing stage opening and closing screen generally adopts several modes such as liquid separating pressure transmission, screw rod transmission, horizontal traction transmission and the like, and in the several modes, the hydraulic transmission precision is lower and is not suitable for occasions with larger opening and closing strokes. Although the screw transmission has high precision, when the screw transmission is applied in a large stroke, the screw is too long, so that the processing and the installation are inconvenient, and the cost is higher. The horizontal traction transmission can realize transmission with large stroke, but the precision is insufficient. The transmission modes have a problem that the transmission modes are generally only suitable for opening and closing of double screens, and are not easy to realize due to structural factors in the occasions of opening and closing and moving of multiple screens.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model aims to provide an open-close screen driving device, for realizing above-mentioned purpose, the utility model discloses the technical scheme who takes is:
the utility model provides a screen drive arrangement opens and shuts, includes screen body subassembly, the upper and lower both ends of screen body subassembly are fixed connection slider respectively, the slider respectively with slide rail sliding connection, fixed connection motor gear subassembly on the screen body subassembly, motor gear subassembly's gear and rack toothing are connected, rack and slide rail parallel arrangement.
Preferably, the display screen is fixedly connected below the screen body assembly.
Furthermore, the screen body subassembly is 2, and the symmetry sets up the upper and lower both ends at the display screen.
Preferably, the motor gear assembly further comprises a motor, and a transmission shaft of the motor is fixedly connected with the gear.
Preferably, the rack is located below the screen assembly.
Preferably, the screen body assembly is connected with the sliding block in a welding mode.
The utility model discloses simple structure is applicable to the occasion that opens and shuts of shielding more, and the stroke is big, the precision is high, can install a plurality of display screens simultaneously.
Drawings
Fig. 1 is a top view of the opening and closing panel driving device of the present invention.
In the figure: 1. a first vertical bar; 2. a second vertical bar; 3. a first cross bar; 4. a second cross bar; 5. a slider; 6. a slide rail; 7. a gear; 8. a rack; 9. a display screen.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the opening and closing screen driving device comprises a screen body assembly, wherein the upper end and the lower end of the screen body assembly are respectively and fixedly connected with a sliding block 5, the sliding blocks 5 are respectively and slidably connected with a sliding rail 6, a motor gear assembly is fixedly connected onto the screen body assembly, a gear 7 of the motor gear assembly is meshed with a rack 8, and the rack 8 is parallel to the sliding rail 6. The screen body assembly comprises a first vertical rod 1 and a second vertical rod 2, a middle upper part position fixed connection first transverse rod 3 between the first vertical rod 1 and the second vertical rod 2, a middle lower part position fixed connection second transverse rod 4 between the first vertical rod 1 and the second vertical rod 2, the end parts of the first vertical rod 1 and the second vertical rod 2 are respectively fixedly connected with a sliding block 5, the sliding block 5 is respectively in sliding connection with a sliding rail 6 parallel to the first transverse rod 3 and the second transverse rod 4, a middle part position fixed connection motor gear assembly of the first transverse rod 3, and a gear 7 of the motor gear assembly is meshed with a rack 8 and is connected with the rack. The screen assembly may be a unitary structure formed by joining different structural components.
The screen body subassembly is fixed connection display screen 9 below the second horizontal pole 4, the motor gear subassembly still includes the motor, the transmission shaft and the gear 7 fixed connection of motor, drive gear 7 through the positive and negative commentaries on classics of motor and rotate, because gear 7 and rack 8 meshing, and then drive screen body subassembly and pass through slider 5 and move on slide rail 6 to drive the display screen and remove. The control of the motor can be controlled by a remote controller.
The screen body subassembly can be 2, and the symmetry sets up the upper and lower both ends at display screen 9, with display screen 9 fixed mounting between the screen body subassembly, fixed firm more reliable.
The rack 8 is positioned below the screen body assembly and provides space for the horizontal movement of the screen body assembly.
The both ends of the first horizontal pole 3 and the second horizontal pole 4 of the screen body subassembly are connected with first montant 1 and second montant 2 through the welding mode respectively, the both ends of first montant 1 and second montant 2 are connected with slider 5 through the welding mode respectively, and are connected through the welding mode, and the rigidity is stronger for connect more firmly reliably, increase life.
As shown in fig. 1, this embodiment provides a schematic structural diagram of three sets of opening and closing screen driving devices used simultaneously, which can realize multi-level independent opening and closing operations, two ends of the sliding rail 6 and the rack 8 are respectively fixedly connected with a wall or related fixing equipment, and when the display screen 9 is required to be opened and closed to move in the use process, the motor-driven gear 7 in the motor-gear assembly rotates, and the sliding block 5 of the screen assembly moves on the sliding rail 6 due to the meshing of the gear 7 and the rack 8, thereby realizing the opening and closing movement of the display screen 9.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
