Embodiment
A kind of dual fail-safe sealing lock, including lock body 1 and steel cable 2, the one end of steel cable 2 are fixedly connected on lock body 1, described lock
Lockhole 1-1, lock body inner chamber 1-2 and lower lockhole 1-3 are from top to bottom coaxially offered in body 1, installation is superimposed in the 1-2 of lock body inner chamber
There are upper and lower two lock cores 3, lock core 3 includes lock gall 3-1, spring 3-2, latches 3-3 and steel ball 3-4, and lock gall 3-1 is set in lock body
In the 1-2 of inner chamber, the diameter of lock gall 3-1 diameter and lock body inner chamber 1-2 matches, and the cone of up/down perforation is offered in lock gall 3-1
Shape lock gall cavity 3-5, lock 3-3 and spring 3-2 be set in taper lock gall cavity 3-5, lock 3-3 in upper lockhole 1-1
The coaxial lock through hole 3-6 for offering up/down perforation, latch the steel ball hole that lateral direction penetrating is offered on 3-3, steel ball 3-4 activity peaces
In steel ball hole, the outside that steel ball hole is reached on the outside of steel ball 3-4 contacts with taper lock gall cavity 3-5 inwall, steel ball
It is extend on the inside of 3-4 in lock through hole 3-6, the equal top pressure in upper end of the spring 3-2 in upper and lower two lock cores 3 is inside it
Latch 3-3 lower ends, the spring 3-2 lower end top pressures in upper lock core 3 are at the top of the lock gall 3-1 of lower lock core 3, the spring in lower lock core 3
3-2 lower ends top pressure is in lower lockhole 1-3 inner side.
Described lock body 1 is into a rectangular parallelepiped structure.
Described one end of steel cable 2 is fixedly connected on lock body 1 and opened up on lockhole 1-1 face, and upper lockhole 1-1 is close to the face
Center is set, the eccentric setting of steel cable 2.
The described one end of steel cable 2 away from lock body 1 uses tapered end face structure setting.It is easy to steel cable 2 to pass through upper lockhole 1-
1st, lower lockhole 1-3 and lock through hole 3-6.
Described lock body inner chamber 1-2 and lock gall 3-1 is arranged to the cylindrical-shaped structure being mutually matched.
Described lock 3-3 is arranged to pyramidal structure corresponding with taper lock gall cavity 3-5.
Size design, its size such as described upper lockhole 1-1, lower lockhole 1-3 and lock through hole 3-6 may pass through steel cable 2.
It is arranged inside described lock body inner chamber 1-2 lower end and is fixed with lower locking closure 4, lower lockhole 1-3 is opened in lower locking closure 4
On, the spring 3-2 lower end top pressures in lower lock core 3 are in the inner side of lower locking closure 4.
In use, the free end of steel cable 2 is sequentially passed through into upper lockhole 1-1 and upper lock through hole 3-6, will by external force
Upper lock 3-3 is pushed down on, while steel ball 3-4 is moved to both sides.Similarly, through the lock core 3 of lower section, through next
Through hole 3-6 is latched, is finally passed by lower lockhole 1-3.By spring 3-2 restoring force, make lock 3-3 returns, so that steel ball
3-4 moves inward, and squeezes steel cable 2 and press, and steel ball 3-4 is stuck by steel cable 2, plays reverse locked effect.
As shown in Figure 1：When steel cable 2 is worn downwards, the free end of steel cable 2 can be pulled downward on, reversely lifts steel cable 2
When, due to taper lock gall cavity 3-5 and lock 3-3 taper structure design so that taper lock gall cavity 3-5 inwall is continuous
Steel cable 2 is extruded by steel ball 3-4, reaches the increasingly tighter purpose of steel cable 2.
