Embodiment：
As shown in figs 1 to 6, present embodiment uses following technical scheme：It includes cover board support 1, cover plate support arm
2nd, cover plate torsion spring 3, sleeve pipe 4, threaded screw rod 5, safe hook assembly 6, upper limit bar 7, lower limiting board 8, operation panel 9 and limited block
10, it is fixedly connected between cover board support 1 and cover plate support arm 2 by cover plate torsion spring 3, sleeve pipe 4 is welded with cover board support 1, as
Revoling tube is fixed, is provided with threaded screw rod 5 in sleeve pipe 4, the both ends of threaded screw rod 5 pass through the spacing fixation of nut, threaded screw rod
5 are welded as a whole by nut and safe hook assembly 6, and safe hook assembly 6 is on the sleeve pipe 4 being welded on cover board support 1, the upper limit
Position bar 7 is welded on cover board support 1, and lower limiting board 8 is welded on cover plate support arm 2, and one end of safe hook assembly 6 is provided with operation
Plate 9 and limited block 10.
Wherein, the described length of sleeve pipe 4 is slightly larger than the width 3-5mm of cover plate support arm 2, avoids the safe scratching cover plate of hook assembly 6
Support arm 2, it can rotate freely；Described upper limit bar 7 fixes limit point as first, for limiting installation hook assembly 6
Maximum open position, prevent safe hook assembly 6 rotates through from turning over, cause automatic safe limit function to fail；Described lower limiting board
8 as the second fixation limit point, and effect is when cover plate closing, holds cover board support 1 temporarily, promotes the anti-hook assembly of cover plate to have
Operating position correctly is treated, described upper limit bar 7 and lower limiting board 8 are used in combination, and control the motion angle of safe hook assembly 6
In the range of 17 °, while 20 ° of the initialization angle of safe hook assembly 6, the dieback of limited block 10 when can avoid the cover plate from opening
, there is dead-centre position in safe hook assembly 6, realizes the smooth opening of cover plate.
For present embodiment when cover plate is opened from closure state, the movement locus of limited block 10 is with cover plate support arm 2
Turning effort under hold up safe hook assembly 6 naturally, until cover plate completely open after, safe hook assembly 6 hooks limit using deadweight
Position block 10, without single manual operation, it is achieved that the defencive function of safe spacing.
Present embodiment is hooked on the limiting plate of cover plate support arm 2 when safe hook assembly 6 works using deadweight, is prevented
Only cover plate closes suddenly, plays safeguard protection effect, and when cover plate is opened, limited block 10 jacks up safety door hook according to movement locus, when
When cover plate fully opens, hold-down hook is naturally hooked on limited block 10, multiple to play safe spacing effect again, and safety door hook is initially installed
20 ° of position horizontal sextant angle, avoid holding out against peace hook in cover plate opening procedure and dead-centre position occur, can smoothly open, upper limit
Bar 7, which limits safe hook assembly, to be crossed and turns over, and is coordinated lower limiting board 8, is made the safe scope of activities of hook assembly 6 in 17 ° of angular ranges, is ensured
It can smoothly rise and close, and performance should have effect.
Present embodiment is when cover plate needs closure, it is necessary to which manual operation is lifted up safe hook assembly 6, cover plate side
Rotatable closure, contingency is avoided completely, after the disengaging safety door hook of cover plate limited block 10 is spacing, operating personnel can send
Safe hook assembly 6 is opened, now, safe hook assembly 6 is ridden on lower position block 8, in wait work using nature falling of conducting oneself with dignity
Initial position, so circulation, utilize the safety hook device of cheap and simple, you can easily realize the protection of die cover plate safe spacing
Effect.
Present embodiment slides picking-up partial dot using limited block 10 has R5 chamferings, and center of gravity is located at hinge central point
Left side, its torque effect formed are enough to make safe hook assembly rotate freely around hinge central point.
Present embodiment is reasonable in design, tailored appearance, and installation is simple, facilitates durable, and cost is cheap, utilizes letter
Single safety hook device can improve the security performance of segment die, avoid, because external force effect causes cover plate to close suddenly, preventing
Contingency occurs, and automatic rise is closed during use, without artificial individually operated, without single power drive, has simple in construction
The characteristics of safe and reliable.
