Description

Work light protection grille combination structure

This invention relates to a work light protective grille assembly structure, which can facilitate the replacement of the bulb in the work light grille, and easily and quickly disassemble and lock the grille on the work light. It particularly relates to the work light protective grille combination. The structure consists of external threads of the lamp holder, an inner ring at the rear end of the grille, and a fixed ring sleeve with internal threads.

Work lights currently used in maintenance sites such as construction sites, factories, automobiles, or ships are mainly used to provide personnel with the ability to move hand-held lights to the required lighting location and provide temporary lighting sources for inspectors and maintenance personnel. This type of work light has a lamp holder on the handle, and the lamp holder can be locked with the bulb. A grille made of metal wire is arranged around the lamp holder and the bulb to protect the bulb in the grille and prevent the work light from burning. Accidentally bump or break the bulb during operation.

The structure of the above-mentioned traditional work lights is shown in patent cases such as Announcement No. 160801 "Vehicle Repair Work Lamp Cover" and Announcement No. 163871 "Vehicle Repair Work Lamp Holder". The grille is composed of two half lampshades of the same shape. It is formed by relative locking in the left and right directions. The other is to set a clamping ring at the rear end of the grille, and at the same time lock the clamping ring on the lamp holder of the work lamp through bolts and nuts. With these structures, when users need to replace the light bulb, they must use a screwdriver to loosen the bolts and nuts and remove the grille on the work light before the light bulb can be replaced, which causes inconvenience and time-consuming lock installation. In particular, work lights are often used in dim and relatively narrow workplaces such as construction sites, factories, or car repairs. Tools must be used to disassemble and install the light bulbs, causing inconvenience and trouble in use.

In view of this, the inventor has accumulated many years of research and practical experience in related fields, and specially created a work light protection grille assembly structure to improve the above-mentioned shortcomings of the conventional technology.

The purpose of this creation is to provide a work light protective grille combination structure that can The user can disassemble and replace the bulb in the work light grille with bare hands without using any tools, and can easily lock and install the grille on the work light.

In order to achieve the above purpose, the present invention is a work lamp protective grille assembly structure. The work lamp includes a generally columnar lamp holder and a grille. One end face of the lamp holder is provided with a bulb screw interface, which is characterized by: The lamp holder is provided with a positioning portion on the outer peripheral wall of the bulb screw interface, and the positioning portion is provided with a stopper at a position opposite to the bulb screw interface; the rear end of the grille is provided with an outer ring portion, and the outer ring portion is There is an inner ring part in the center of the lamp holder. The inner ring part can be placed around the periphery of the positioning part of the lamp holder and against the stopper part. The positioning part is detachably equipped with a fixed ring sleeve so that the grille can be The inner ring part can be clamped between the stopper part and the fixed ring sleeve, so that during use, the bulb and the grille can be easily and quickly disassembled and locked, thereby improving the convenience of use.
