Description

Technical Field

[0001] The utility model relates to the technical field of helmet production, in particular to a fixing device for helmet production. Background Art

[0002] A helmet is a piece of safety equipment used to protect the head from impact and external damage. During the processing of the helmet, after the shell processing is completed, it generally goes through steps such as spraying primer, spraying topcoat, printing, and spraying varnish. During this process, multiple painting operations are required, so the helmet needs to be fixed.

[0003] For example, the application number is CN202222810389.9. The utility model discloses a fixing device for helmet production, which relates to the technical field of helmet production equipment. The fixing device of the utility model includes a column, and at least two electrically controlled telescopic devices are arranged on the top circumference of the column. The ends of the electrically controlled telescopic devices are connected to an abutting structure that abuts against the inner wall of the helmet, and the abutting structure can be deformed under force; the column is arranged vertically, and the electrically controlled telescopic device is arranged horizontally; the abutting structure includes a connecting block connected to the end of the electrically controlled telescopic device, and the end of the connecting block is connected to an arc plate that abuts against the inner wall of the helmet. The utility model uses at least an electrically controlled telescopic device and an abutting structure that abuts against the inner wall of the helmet at its end, and uses the structure to fix and process the helmet, thereby solving the problem of the existing lack of fixing of the helmet. When the airflow or liquid flow of the spray paint is applied to the helmet, the helmet will be subjected to force to cause displacement on the processing table, thereby causing inconvenience in processing.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the existing problem that the helmet is generally only placed on the processing table and lacks fixation of the helmet, when the airflow or liquid flow prepared by the paint spray is applied to the helmet, the helmet will be forced to move on the processing table, thereby causing processing inconvenience. However, during use, when the arc plate is used to fit the inner wall of the helmet to the outside to tension it, the inner wall of the helmet shell is prone to slipping with the outer side of the arc plate, resulting in the user's manual support before the helmet is fixed to ensure complete tension, which reduces the fixing efficiency of the helmet shell and affects the subsequent processing efficiency of the helmet.
