A device for spraying the inner surface of a lamp housing using a spray head without dead angle spraying

Abstract

The invention relates to the technical field of spraying devices, in particular to a spraying device for the inner surface of a lamp housing that uses a spray head to spray without dead ends. The following solution is now proposed, which includes a base, and two fixing plates are fixedly connected to the base. A first sliding block is slidably connected, a second threaded column and a second sliding column are arranged between the two first sliding blocks, the second threaded column is threadedly connected with a second sliding block, and a second sliding block is opened on one side of the second sliding block. A groove, a threaded sleeve is rotatably connected in the first groove, a first ratchet wheel and a second ratchet wheel with opposite tooth directions are fixedly connected to the outside of the threaded sleeve, a rotating column is rotatably connected in the first groove, and the external connection of the rotating column is There are first pawls and second pawls, and the top surface of the second slider is provided with a nozzle body. The invention achieves the complete spraying without dead angle on the inner top surface of the lamp housing body, improves the spraying efficiency, avoids physical damage to workers caused by manual spraying, and the spraying is relatively uniform.

Description

technical field [0001] The invention relates to the field of spraying devices, in particular to a spraying device for the inner surface of a lamp housing which uses a spray head to spray without dead angle. Background technique [0002] In order to maintain a long service life of some lamps and lanterns lighting devices used in open air or humid environments, the inner surface of the lamp housing needs to be painted. Therefore, there are often a plurality of partitions in the lamp housing, and the existing spraying equipment in the process of painting the inner surface of the lamp housing, due to the blocking of the partitions, when the angle of the nozzle body is inclined , the inner part of the lamp housing is often not sprayed with paint, resulting in poor painting effect and reduced product processing efficiency. SUMMARY OF THE INVENTION [0003] In order to solve the problems in the prior art, the present invention provides a device for spraying the inner surface of ...

Problems solved by technology

[0002] Some lamps and lighting devices used in open air or humid environments, in order to maintain a long service life, the inner surface of the lamp housing needs to be painted, because the lamp housing has certain characteristics for the components installed inside it. Therefore, there are often multiple partitions in the lamp housing, and the existing spraying equipment is in the process of painting the inner surface of the lamp housing, due to the blocking of the partitions, when the angle of the nozzle body is inclined , the inner part of the lamp housing is often not sprayed with paint, resulting in poor paint spraying effect and reducing the product processing efficiency. Therefore, the present invention proposes a device for spraying the inner surface of the lamp housing by using a spray head without dead ends.
