Abstract
The utility model discloses a safety helmet portable of loading and unloading a face guard, relating to a safety helmet and a helmet, belonging to a device which can conveniently load and unload a face guard or an adapter. The device comprises a base, and a rotatable connecting block. The connecting block is provided with a fixing device. The utility model has the advantages of convenient operation, flexible operation, and high safety. The face guard can be conveniently loaded and unloaded at any time, and the working safety helmet can satisfy the different requires of different conditions when using.
Description
The utility model belongs to protective work helmet, the helmet.
General protective work helmet does not have face shield at present, it is to be fixedly connected as its face shield of helmet welding helmet and cap body that the protective work helmet of face shield is arranged, so its function singleness of work on hand safety cap, for satisfying different occasions, the use that different situations need is unsatisfactory.
The new purpose of this practicality provides a kind of protective work helmet that can load and unload face shield or attachment device at any time easily, the convenient, flexible property the when function of use of enhancing safety cap and use.
Solution of the present utility model is but that the device of a pair of conveniently assemble and disassemble face shield is installed on protective work helmet, this device is made up of a firm banking and dress rotating coupling block thereon, and fixture is arranged on the coupling block.
Fig. 1 is that band is convenient to load and unload the protective work helmet of face shield device or the helmet, welding helmet.
Fig. 2 is the apparatus structure schematic diagram that the utility model is convenient to load and unload face shield.
Fig. 3, the 4th, the structural representation of the coupling block of handler.
Fig. 4 is Fig. 3 I-I cutaway view.
Fig. 5, the 6th, the structural representation of the fixture on the handler.
Fig. 6 is Fig. 5 II-II cutaway view.
The protective work helmet 1 that band shown in the accompanying drawing 1 is convenient to load and unload face shield 2 is that hard material is made or the hard structure that can fix this device is arranged.This handler 2 is to be fixed on the safety cap 1.
Fig. 2 has described device 2, and its coupling block 5 is contained on the bowl-shape firm banking 7, at the space of base 7 11 built-in springs 8,9.Pressure with spring 8 makes the bossing 12 of coupling block 5 compress base 7, the frictional force when producing coupling block 5 rotations.Rubbing surface 13,14 can be the band ripple, preferably is lined with rubber washer 6.Slotted eye 16 and the slotted eye 17 that is used for mounting fixing parts 10 that one connection face shield connecting rod 15 is arranged on the coupling block 5.Fixture 10 is subjected to the pressure effect of spring 9.Knob 4 is fixedly connected with fixture 10, and control fixture 10 rises and falls.
During operation, knob 4 is depressed, driven fixture 10 and move, the concave portion 18 on the fixture 10 is taken in the slotted eye 17, opened slotted eye 16 simultaneously.With the connecting rod 15 insertion groove endoporus 16 of face shield or other annex, fixture 10 automatically resets under spring 9 effect and makes its recess 18 block cooperation place on the connecting rod 15, fixes bar 15 and does not come off.
The utility model is easy to operate, uses flexibly, can at any time load and unload easily face shield or other annex, and the different needs in the time of can making protective work helmet satisfy different situations uses. Can make a cap multiplex, improve the serviceability of protective work helmet.
