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

Embodiment 1

[0042] see Figure 1-Figure 7 As shown, the present embodiment provides a drilling device based on a multi-directional fixed breathable safety helmet, including a support plate 100 and a fixed drilling mechanism 200 above the support plate 100. The edge of the support plate 100 is provided with a lifting frame 110, and the lifting frame 110 An electric push rod 111 is embedded in the bottom of the cavity.

[0043] In order to improve the support stability, the bottom of the support plate 100 is provided with support legs 120 near the four corners, and the bottom of the support legs 120 is provided with a stabilizing plate 121. The stabilizing plate 121 can increase the contact area with the ground, improve the frictional force, and avoid slipping, so that The four support legs 120 support the support plate 100 more stably.

[0044] The fixed drilling mechanism 200 at least includes:

[0045]Lifting plate 210, one end of lifting plate 210 is slidingly arranged inside lifting ...

Embodiment 2

[0053] Considering the wear caused by the rigid extrusion of the bottom of the gripping rod 224 and the sliding sleeve 222 against the outer wall of the helmet, the difference between this embodiment and Embodiment 1 is that, please refer to Figure 8 shown, where:

[0054] In order to improve the clamping effect of the clamping rod 224 and avoid clamping wear, the end of the clamping rod 224 is provided with a chute 2241, the end of the chute 2241 is provided with a rubber head 2242, and the end of the rubber head 2242 is connected with a slide bar 2243. The rod 2243 is slidably arranged inside the chute 2241, and a sliding spring 2244 is fixedly connected between the sliding rod 2243 and the end of the inner cavity of the chute 2241, so that the sliding spring 2244 can be compressed when the end of the gripping rod 224 is attached to the outer wall of the safety helmet. , under the elastic force of the sliding spring 2244, not only the clamping effect can be improved, but at...

Embodiment 3

[0057] Considering that the dust attached to the inner wall of the cavity 2220 is inconvenient to clean, and it is easy to cause blockage for a long time, the difference between this embodiment and Embodiment 1 is that, please refer to Figure 9-Figure 10 shown, where:

[0058] A turntable 2221 is installed inside the cavity 2220. The bottom of the turntable 2221 is provided with a brush plate 2225. The outer surface of the brush plate 2225 is provided with a plurality of brushes 2226. The ends of the brushes 2226 are attached to the inner wall of the cavity 2220 to make the turntable 2221 rotate. Inside the cavity 2220, the brush plate 2225 is driven to rotate inside the cavity 2220, so that the brush 2226 sticks to the inner wall of the cavity 2220 for brushing, which is convenient for brushing off the attached impurities and subsequent cleaning.

[0059] In order to improve the degree of automation, the outer wall of the turntable 2221 is provided with a cam 2222, and the o...

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 ...
