The medial surface of shell 44, the support pedestal 423 carry out locking connection, the rope 424 and drawing by fixing axle with zipper box 422
422 axis connection of lock box, the clamping plate of the stable push plate 421 is a kind of flexible board and upper surface constitutes an arc snap-gauge, under
The arc length that end face is constituted is small, the rigid tough plate of the support pedestal 423, carries out extruding contraction to zipper box 422, it is existing all
It is to be supported by some foam-rubber cushions, though sponge is flexible not to support the helmet, so that helmet side contacts knot with temporal bone
Structure is unstable, carries out locking limit to the card slot on temporal bone by stablizing to move in push plate 421, connects by support pedestal 423
Dynamics between temporal bone and the helmet, so that the side helmet has body supports, helmet structure stabilization will not be damaged.
Mechanism for card 43 includes zipper belt 431, rear stop collar 432, pressing mechanism 433, location structure plate 434, rank after described
Dynamic pressure-resisting plate 435, the zipper belt 431 are vertically arranged to the inside of pressing mechanism 433, and the location structure plate 434 passes through shifting
Moving axis bar is fixedly connected with location structure plate 434, and the pressing mechanism 433 is horizontally installed to the inside of rear stop collar 432,
Described to hold in the mouth dynamic pressure-resisting plate 435 and 431 mechanical engagement of zipper belt, the pressing mechanism 433 includes ball 4331, tortuous slide plate
4332, it interlocks and pushes away column 4333, the ball 4331 is flexibly connected with zipper belt 431, and the complications slide plate 4332 is presented 30
Degree angle is installed on the left side for interlocking and pushing away column 4333, and the ball 4331 is slidably connected by outer junction and tortuous slide plate 4332,
The ball 4331 pushes away column 4333 with gearing and passes through the tortuous progress of slide plate 4332 mechanical engagement, and dynamic 4354 jiaos of the pressure-resisting plate of rank is in
The torsion of S type is presented in existing 4 jiaos of progress quadrangle star installations of half a month arc, pressure-resisting plate when upper end expands, complications slide plate 4332 bending,
It is pushed while can be limited, since occipital bone is the state that convex lower recess is presented when the existing helmet is worn, leads to head
Helmet rear portion, which is worn, to be occurred hollow, and helmet rear does not have the support of occipital bone to be easily impacted damage, passes through 434 sinciput of location structure plate
Occipital bone is supported and guarantees that the rear helmet has sufficient stress point.
A kind of working principle of steady device: vertical direction moves down the helmet after the helmet is placed in right above head by fireman
It slowly moves down to overhead, buffer plate 414101 is squeezed so that on buffer plate 414101 by the parietal bone on head
Deformation occurs for arc mating groove 414102, is transformed into shape corresponding with parietal bone by parietal bone extruding and is fitted closely, passes through top
Bone pushes movable plate 414104 to move up along sliding slot 4143 extruding of buffer plate 414101, passes through movable plate 414104
Helical teeth plate 4144 is carried out to squeeze transmission toughness arc plate 4145, so that buffer plate 414101 has the elasticity shunk, is led to simultaneously
Crossing toughness arc plate 4145 pushes push plate 4142 to move up transmission connection tube 413, by being equipped with rotation axis below connection tube 413, so making
Obtaining matching mechanism 414 can be rotated with engagement head, while being driven connection tube 413 and being moved up external 415 turns of ring flat-plate of rotation drive
It is dynamic, rope 424 is wrapped on the embedded sliding rail of external ring flat-plate 415 by the rotation of external ring flat-plate 415, rope 424 pulls zipper
Box 422 embeds axis and is rotated, and is supported fitting to the temporal bone on head so that stablizing push plate 421 and being moved towards inside,
By supporting pedestal 423 to be attached the side structure of temporal bone and the helmet, guarantee the stabilization of side structure, while passing through linking
Pipe 413 moves up the dynamic pressure-resisting plate 435 of promotion rank and moves up, and the expansion plate by holding in the mouth dynamic 435 top of pressure-resisting plate is supported helmet top
Structure cooperation is carried out to parietal bone, while being moved up by the dynamic pressure-resisting plate 435 of excessively high rank and zipper belt 431 is pulled to be driven on ball 4331
It moves, 4331 lateral surface of ball is smooth to push tortuous slide plate 4332 to be slided by the stabilization single track that gearing pushes away column 4333, so that tortuous sliding
Plate 4332 pushes location structure plate 434 to lock occipital bone, guarantees that helmet rear has occipital bone to carry out structural support, so that the helmet is worn
It is firm, it is therefore prevented that the helmet does not connect with the main skull structure on head because of top, side, rear, causes helmet structure branch
Support face is insufficient, and for the helmet easily after being impacted, the insufficient position breakage of supporting surface causes head injuries.
Basic principles and main features and advantages of the present invention of the invention, It should be understood by those skilled in the art that this hair
Bright to be not restricted to the described embodiments, the above embodiments and description only illustrate the principle of the present invention, Hen Duoxiu
Change and change for the ordinary skill in the art is it will be apparent that selection and description embodiment are in order to more all right
Bright the principle of the present invention and practical application.
