Description
Technical Field
The utility model relates to a straight following formula classroom lamp especially relates to a straight following formula classroom lamp of portable regulation mounted position, belongs to classroom lamp technical field.
Background
At present, straight following formula classroom lamp is the lighting apparatus commonly used that is applied to in the classroom, and it has the effect of anti-dazzling light, and classroom lamp's major structure is: after the diffusion plate is added, the light emitted by the luminous body is emitted in a surface shape, then the grid is added on the surface of the luminous plate to improve the anti-glare capability of the luminous plate, but in practical popularization and application, the current classroom lamp adopts the hanging rods directly connected on the outer shell, so that the distance between the connection points is fixed and cannot be adjusted, and the distances between the hanging rods which are reserved for different areas and different classrooms are different, thereby limiting the application of the classroom lamp; especially, when upgrading and transforming old classrooms, the reserved suspender cannot be changed in position, so that the reserved suspender cannot be matched with the existing classroom lamp, and the classroom lamp with different hoisting positions needs to be matched, thereby seriously limiting the popularization and application of the classroom lamp and increasing the installation and use cost of the classroom lamp.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned not enough, provide a wide straight following formula classroom lamp of application scope, its accessible adjustment is convenient be applied to under the different occasions.
The purpose of the utility model is realized like this:
a direct type classroom lamp comprises a housing enclosed and fixed by a housing, a PCB circuit board arranged in the housing is attached with a light-emitting element, a light-emitting surface of the housing is provided with a diffusion plate, and a grating enclosed and fixed by the housing is attached on the diffusion plate; sliding grooves are formed in the two sides of the outer shell along the length direction of the outer shell, sliding plates are arranged at the two ends of the U-shaped hanging plate, and the sliding plates are slidably embedded in the sliding grooves; and a fastening screw is screwed on the U-shaped hanging plate, and the end part of the fastening screw is pressed on the outer wall of the outer shell.
The utility model relates to a straight following formula classroom lamp, the spout includes the bar cell body and is located the card strip constitution on two cell walls of bar cell body.
The utility model relates to a straight following formula classroom lamp, the shell body is a frame shape structure, and housing and grid joint respectively in the upper portion and the lower part of this frame shape structure.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model realizes sliding connection through the sliding U-shaped hanging plate arranged in a sliding way, thereby facilitating the adjustment of the distance according to different hoisting positions, and particularly, when upgrading and transforming old classrooms, the hoisting positions can be conveniently adjusted to adapt to different suspender distances, therefore, the product has universal matching property and is convenient for transforming old teaching environments; meanwhile, the outer shell and the housing are separately designed, the outer shell and the U-shaped hanging plate are made of metal, and when the housing is made of plastic, the connection strength is improved, and the manufacturing cost and the overall weight are reduced; when better strength is needed, the housing is also made of metal materials; simultaneously, adopt the mode of joint in both sides through the U-shaped hanger plate and connect to it is more firm to make to connect, prevents the production of rocking.
