Description
Technical field
This utility model relates to head hoop technical field, is specially a kind of head hoop elasticity adjusting device.
Background technology
Head hoop is mounted in weld cap inside, is used for being worn over head, weld cap is fixed on to the product of workman's head.Traditional head hoop is directly fixed in weld cap, cannot regulate head hoop size, causes a medicated cap can not adapt to the crowd of different head size, and what affect workman normally wears use, and for this reason, we propose a kind of head hoop elasticity adjusting device.
Utility model content
The purpose of this utility model is to provide a kind of head hoop elasticity adjusting device, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of head hoop elasticity adjusting device, comprise that fixed screw, adjusting knob, fixed gear are buckled, fixing upper bar and fixing lower bar, after head hoop being installed on described fixing lower bar, be with, described fixed gear button is arranged on fixing upper bar, the cutting of described fixing upper bar be arranged on after head hoop with installing hole on, described adjusting knob is fixed on fixed gear by fixed screw and buckles.
Preferably, two of described fixing lower bar be provided with after head hoop with installing hole and fixed mechanism.
Preferably, the centre of described fixing lower bar is provided with a fixed leg structure.
Preferably, described fixed leg is a female thread structure, and is connected with fixed screw.
Preferably, described head hoop elasticity adjusting device is arranged on head hoop.
During use, operator are when installing this fixed structure, first headband being positioned over to elasticity regulates between fixing upper bar and fixing lower bar, again the fixed gear of elasticity adjusting knob is clamped in the circular hole of fixing upper bar and fixing lower bar, put elasticity adjusting knob, tighten elasticity fixed screw, head hoop elasticity adjusting device is fixed, this has just completed the installation of head hoop elasticity adjusting device.
Compared with prior art, the beneficial effects of the utility model are: this head hoop elasticity adjusting device, and weld cap is worn the requirement that meets different crowd, and the head of more fitting uses comfortable.
