Embodiment
Following embodiments are used to illustrate the present invention, but are not limited to the scope of the present invention.
Embodiment 1
Referring to Fig. 1~2, which includes seal casinghousing and connecting rope 1, is offered on seal casinghousing for connecting rope 1
The connecting hole passed through, seal casinghousing is interior to be equipped with locking bushing 3, locking sphere 5 and Lock spring 6, and locking bushing 3 is axially slidably
It is arranged in seal casinghousing, the end of connecting rope 1 passes through 3 inner side of insertion locking bushing after connecting hole, the lower end side of locking bushing 3
Face offers the through hole of two transverse directions, and two locking spheres 5 are symmetricly set in two through holes, the inner side of seal casinghousing be equipped with
The corresponding conical inboard wall 9 of sphere 5 is locked, Lock spring 6 is arranged between seal casinghousing and locking bushing 3, and Lock spring 6 pushes away
Dynamic locking bushing 3 is moved to close to the side of conical inboard wall 9.
The other end of connecting rope 1 is equipped with the needle body 102 in insertion connecting hole, and annular is offered on the circumference of needle body 102
Locating slot 101, in the convenient insertion connecting hole of needle body 102, easy to operate, locating slot 101 and locking sphere 5 on needle body 102
Cooperation can improve locking effect, prevent artificial opposite direction from twitching connecting rope 1.Locating slot 101 in the present invention has interval setting
It is multiple.
Seal casinghousing includes sealing shell 2 and is fixed on the sealing inner casing 4 of the inner side of sealing shell 2, and conical inboard wall 9 is set
In the lower part of 4 inner side of sealing inner casing, the upper end of sealing inner casing 4 is fixedly connected with a spring stop piece 7, the upper end of locking bushing 3
Through spring stop piece 7, the upper end sealed set of sealing shell 2, the lower end of locking bushing 3 is equipped with diameter and is more than in locking bushing 3
The locking step 301 of portion's diameter, through hole are opened in 301 sidepiece of locking step, and Lock spring 6 is arranged on spring stop piece 7 and locking step 301
Between.The upper end of locking bushing 3 is fixed with a unlocking part 8, and the material of unlocking part 8 is iron, and unlocking part 8 is arranged on spring stop piece
7 upside.Spring stop piece 7 is the nonmagnetic substances such as copper, aluminium, zinc.
Operation principle and process：The needle body 102 of connecting rope 1 is covered through insertion locking after the connecting hole of 4 bottom of sealing inner casing
The inner side of cylinder 3, in the process since Lock spring 6 is pressed down against locking bushing 3 all the time, so the two of 3 lower part of locking bushing
A locking sphere 5 forms the extruding to needle body 102 under the extruding of conical inboard wall 9, and needle body 102 overcomes Lock spring 6 upwards
After resistance through two locking spheres 5, the locking of two locking 5 shape buddy lines 1 of sphere.It is close when needing to open
