Abstract
The utility model provides a self-draining lamp box, which comprises a lamp box body, wherein a bottom plate at the lower end of the lamp box body is provided with a water outlet; the water outlet is clamped with a sealing ring; the lower end of the sealing ring is provided with a cover plate which is tightly attached to the sealing ring; the cover plate is hinged to the bottom plate, and an elastic piece is arranged at the lower end of the cover plate. The utility model discloses a theory of operation does: the lamp box is sealed in a mode that the cover plate is tightly attached to the sealing ring, when water accumulates in the lamp box, the cover plate is opened downwards by the gravity of the water to drain, and at the moment, the elastic part is in a deformation state; after the accumulated water is drained, the restoring force of the elastic piece pushes the cover plate to restore the lamp box to a sealing state.
Description
Technical Field
The utility model relates to a lighting apparatus field specifically is a self-draining formula lamp house.
Background
At present, the lamp box is widely applied to public places such as shopping malls, subway stations, bus stations and the like as a propagation medium. Be applied to outdoor lamp house after the rainy day intaking, ponding can be slowly oozed in the lamp house, and ponding can be stored up a period in the lamp house promptly, can not in time be discharged. Rainwater accumulated in the lamp box can damage components in the lamp box, especially cause fatal damage to electrical components in the lamp box, and the service life of the lamp box is greatly shortened. Some lamp houses are in order to in time the drainage, and the mode that adopts the complete fretwork in bottom carries out the drainage, prevents ponding to the harm of the electric components in lamp house and the lamp house, but the degree of sealing of this kind of lamp house is low, and the bottom of fretwork not only can the printing opacity still can get into a large amount of dusts and foreign matters from bottom fretwork, has influenced the performance of lamp house and electric components and parts.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problem that the traditional outdoor lamp box cannot give consideration to both the drainage function and the sealing performance is solved.
The utility model provides a self-draining lamp box, which comprises a lamp box body, wherein a bottom plate at the lower end of the lamp box body is provided with a water outlet;
the water outlet is clamped with a sealing ring;
the lower end of the sealing ring is provided with a cover plate which is tightly attached to the sealing ring;
the cover plate is hinged to the bottom plate, and an elastic piece is arranged at the lower end of the cover plate.
The utility model discloses a theory of operation does: the lamp box is sealed in a mode that the cover plate is tightly attached to the sealing ring, when water accumulates in the lamp box, the cover plate is opened downwards by the gravity of the water to drain, and at the moment, the elastic part is in a deformation state; after the accumulated water is drained, the restoring force of the elastic piece pushes the cover plate to restore the lamp box to a sealing state.
Preferably, a notch is formed in the middle of the sealing ring and connected with the water outlet in a clamping mode. Both ends joint is on the outlet about so the sealing washer, makes the more firm of sealing washer installation.
Because the sealing washer joint is on the outlet, and the sealing washer up end is higher than the bottom plate, can cause a small amount of ponding can't discharge, so this problem is solved in further improvement, and is concrete, the sealing washer upper end is equipped with a plurality of breachs. The design of the notch enables the residual accumulated water to be discharged along the notch, and the problem of residual accumulated water in the lamp box is solved.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The utility model provides a self-draining lamp box, which comprises a lamp box body, wherein a bottom plate 1 at the lower end of the lamp box body is provided with a water outlet 2;
the water outlet 2 is clamped with a sealing ring 3;
a notch 32 is arranged in the middle of the sealing ring 3, and the notch 32 is clamped with the water outlet 2;
the upper end of the sealing ring 3 is also provided with two notches 31, a small amount of accumulated water cannot be discharged due to the fact that the upper end face of the sealing ring 3 is higher than the bottom plate 1, and the design of the notches 31 can discharge the residual accumulated water in the lamp box;
the lower end of the sealing ring 3 is provided with a cover plate 4 which is tightly attached to the sealing ring 3;
the cover plate 4 is hinged with the bottom plate 1, an elastic piece 5 is arranged at the lower end of the cover plate 4, and the elastic piece 5 is a spring.
The utility model discloses a theory of operation does: the lamp box is sealed in a mode that the cover plate 4 is tightly attached to the sealing ring 3, when water accumulates in the lamp box, the cover plate 4 is opened downwards by the gravity of the water to drain, and at the moment, the elastic piece 5 is in a deformation state; after the accumulated water is drained, the restoring force of the elastic piece 5 pushes the cover plate 4 to restore the lamp box to a sealing state.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
