Drilling device for breathable safety helmet based on multi-directional fixing

Abstract

The invention relates to the technical field of safety helmet drilling, and particularly relates to a drilling device for a breathable safety helmet based on multi-directional fixing. The drilling device comprises a supporting plate and a fixed drilling mechanism above the supporting plate, wherein the fixed drilling mechanism at least comprises a lifting plate and a multi-directional fixing device; one end of the lifting plate is arranged in a lifting frame in a sliding mode, a rotating motor is arranged at the top, far away from the lifting frame, of the lifting plate, and an output shaft of the rotating motor rotationally penetrates through the surface of the lifting plate and is connected with a drill rod; and the multi-directional fixing device comprises a fixing sleeve and a sliding sleeve, the fixing sleeve is fixedly connected with the bottom, close to the end part, of the lifting plate, the drill rod penetrates through the interiors of the fixing sleeve and the sliding sleeve correspondingly, a plurality of grabbing and clamping rods are movably connected to the outer wall of the sliding sleeve, hinge rods are hinged between the outer walls of the grabbing and clamping rods and the outer wall of the fixing sleeve, and a cavity is formed in the fixing sleeve. According to the drilling device, multi-directional clamping can be carried out during drilling, the clamping strength is larger along with the deep drilling, so that the deviation of the safety helmet is effectively avoided, and dust can be prevented from drifting away.

Description

technical field [0001] The invention relates to the technical field of safety helmet drilling, in particular to a drilling device for a breathable safety helmet based on multi-directional fixation. Background technique [0002] Safety helmets are protective equipment to prevent impact objects from hurting the head. Consists of shell, lining, lower chin strap and rear hoop. When the worker's head is impacted by falling objects, the helmet shell and cap liner are used to first decompose the impact force to the entire area of ​​the skull, and then use the elastic deformation, plastic deformation and allowable The structural damage absorbs most of the impact force, so that the final impact force on the head of the personnel is reduced to below 4900N, thereby protecting the head of the operator; [0003] In order to ensure air permeability during the production and manufacture of helmets, it is necessary to open vent holes on the outer wall of the helmet, so that the staff can ...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure air permeability during the manufacture of helmets, it is necessary to open vent holes on the outer wall of the helmet, so that the staff can ventilate the head and the external environment when wearing it , improve comfort, and also need to drill when installing other parts, so the helmet needs to use drilling equipment when drilling. Under the driving force of the rod drilling through the safety cap, it is easy to cause the safety cap to move, causing the position between the drill pipe and the safety cap to shift, causing the drilling to tilt or fail, and the current drill pipe is prone to generate a lot of debris when drilling Floating on the table or the ground, it is inconvenient to clean up. In view of this, we propose a drilling device for breathable helmets based on multi-directional fixation
