Automobile roof light box shell locking structure

Abstract

The invention provides an automobile roof light box shell locking structure. The automobile roof light box shell locking structure includes a light box shell, and an upper cover, a lower cover, a panel and a water defender form the light box shell, wherein the lower cover is located below the upper cover, the panel is arranged near the front, and the water defender is arranged near the rear; the water defender is tightly connected between the upper cover and the lower cover, joints among the panel, the upper cover and the lower cover are all locked by adopting mechanical locking structures andtightly abut against one another, and therefore the joints of the whole light box shell are sealed; mechanical locking structures include mechanical nuts and mechanical bolts, wherein the mechanicalnuts are fixed to the panel, the upper cover and the lower cover in advance, and the mechanical bolts are used for being matched with the mechanical nuts; fixing holes for fixed the mechanical nuts are formed in the positions corresponding to the panel, the upper cover and the lower cover. The automobile roof light box shell locking structure has the advantages of being high in connection strength, waterproof and sealed and preventing the plastic shell from cocking and deforming.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a locking structure of a car roof light box shell. Background technique [0002] The car roof light box is a lamp installed on the roof of taxis, cars, trucks, etc., which can display scheduled information and play advertisements. The body is generally made of plastic, and it is necessary to ensure the connection strength between the upper and lower shells, the parts and the shell, the sealing of the shell, and the anti-warping deformation of the plastic shell. The structure of the car roof light box in the prior art is generally relatively simple in design, and The connection strength is low and the sealing is poor. In view of this, the present invention designs a car roof light box shell locking structure which is waterproof and sealed, and which prevents the warping and deformation of the plastic shell. Contents of the invention [0003] The purpose of the present inventio...
