Table invention changes in the tapered end pellet shot from a slingshot hole down the method for the locked lengths of pellet shot from a slingshot can be like this: pellet shot from a slingshot is down made the structure that can regulate its length, by regulate its length change under the locked lengths of pellet shot from a slingshot.As: with positioning connection or be inserted in screw thread, screens method in the pipe of an opening and make down pellet shot from a slingshot, the distance of the relative pipe of pin end face bottom surface can be regulated, thereby can change pellet shot from a slingshot length down with pin.
Ball lock head of the present invention changes in the pellet shot from a slingshot hole down the method for the locked lengths of pellet shot from a slingshot can also random sample: the locked lengths that changes following pellet shot from a slingshot in the pellet shot from a slingshot hole by the following pellet shot from a slingshot in the transposing pellet shot from a slingshot hole.The locked lengths of the following pellet shot from a slingshot of transposing is unequal mutually.
Ball lock head of the present invention changes in the pellet shot from a slingshot hole method of the locked lengths of pellet shot from a slingshot down also can be like this: replace the locked lengths that following pellet shot from a slingshot in the pellet shot from a slingshot hole changes following pellet shot from a slingshot in the pellet shot from a slingshot hole with standby following pellet shot from a slingshot.The locked lengths of standby following pellet shot from a slingshot and the following pellet shot from a slingshot that is replaced is inequality.Can use pellet shot from a slingshot and do standby pellet shot from a slingshot.
The present invention is doing label on the pellet shot from a slingshot down for the ease of the locked lengths of pellet shot from a slingshot under changing in the pellet shot from a slingshot hole.
Ball lock head of the present invention changes the locked lengths of descending pellet shot from a slingshot in the pellet shot from a slingshot hole for the ease of taking out down pellet shot from a slingshot, can make the pellet shot from a slingshot stopple structure of light folding dress, is provided with screw thread such as the pellet shot from a slingshot outer end of hole, does the pellet shot from a slingshot stopple with screw.
The pellet shot from a slingshot stopple is nonvoluntary to be opened by the people ball lock head of the present invention in order to protect, and can do like this: cover thing lock body setting and cover the pellet shot from a slingshot stopple.The lid thing is positioned finger setting on lock body, only could take off from lock body after untiing the location of alignment pin to the lid thing and cover thing.Such as: the lid thing is inserted in the groove on the lock body pellet shot from a slingshot stopple is covered, and under the tapered end locking-in state, activity is inserted in other end insertion that an end in the lock body is pressed on the alignment pin on the sleeve pipe and covers in the locating hole on the thing bottom surface, makes to cover thing and can not pull out.Sleeve pipe slides on the lock core, and movable the insertion in the lock body, under lock-out state, lock core, sleeve pipe and lock body three have the pellet shot from a slingshot hole one by one correspondence communicate.The pellet shot from a slingshot hole is from inside outwards placed following pellet shot from a slingshot, middle pellet shot from a slingshot successively, is gone up pellet shot from a slingshot, spring and pellet shot from a slingshot stopple.The axial displacement of sleeve pipe on lock core is restricted, and alignment pin is pressed on the sleeve pipe under spring action, and alignment pin is pressed in place depression on the circumference of sleeve pipe.When sleeve pipe rotate make alignment pin be pressed in depression when going up alignment pin no longer plug in the locating hole that cover on the thing bottom surface, covering thing can take off.Correspondingly, key has normal key and changes two kinds of keys, the both plays the effect of opening tapered end, different places show: normal key can make down the contact surface of pellet shot from a slingshot and middle pellet shot from a slingshot flush with the contact surface of lock core and sleeve pipe, but the contact surface of pellet shot from a slingshot and last pellet shot from a slingshot all flushes with the contact surface of sleeve pipe and lock body in can not making, can not rotating casing.The change key is then opposite, can rotating casing be untied covering the location of thing by alignment pin, just can open the pinning length of pellet shot from a slingshot under pellet shot from a slingshot changes under the taking-up of pellet shot from a slingshot stopple.
The locked lengths of pellet shot from a slingshot was opened by the people with protection pellet shot from a slingshot stopple is nonvoluntary under ball lock head of the present invention was convenient to change; can also do like this: core is decided in addition between lock core and lock body; deciding core slides on the lock core; movable insert in the lock body but can not rotate; under lock-out state, decide core diameter to corresponding one by one the communicating in radially pellet shot from a slingshot hole that has on pellet shot from a slingshot hole and the lock core, form pellet shot from a slingshot hole system.Pellet shot from a slingshot hole system from inside outwards has following pellet shot from a slingshot successively, goes up pellet shot from a slingshot, spring and pellet shot from a slingshot stopple.Decide core and lock core and form the core lock after axial location, the axial displacement core lock shaft that core is locked in the lock body is located to keeper.Only untiing the core lock shaft behind the location of keeper, just can in lock body, take out the locked lengths that changes following pellet shot from a slingshot the core lock.As: make and have 4 to be 90 ° of unequal protruding arms of distribution height on the hollow cylinder deciding core, the pellet shot from a slingshot hole is radially offered from protruding arm, locating piece as the core lock shaft to keeper, be arranged on the lock core, it is near the end face of deciding core, with decide the core concentric locking collar on lock core, and fixedly connected with lock core, rotate with lock core, the shape of locating piece is identical with the end surface shape of deciding core, and under the tapered end lock-out state, locating piece does not overlap with the end face of deciding core, the hole that mounting core is locked on the lock body is made and is decided core outer rim similar shapes, and corresponding hole wall is provided with the groove that allows locating piece to rotate in the hole of locating piece.Because locating piece does not overlap with the end face of deciding core under lock-out state, the axial displacement of locating piece is subjected to the restriction of groove arm, thereby the axial displacement that core is locked in the lock body is also restricted, having only with key insertion keyhole rotational lock core makes locating piece overlap with the end face of deciding core, limited by cell wall, could take out the core lock.On this structure, can also set up again a lock-bit ring as the core lock shaft to keeper, the people of the key of accomplishing only to change could take out the possibility of core lock.The lock-bit ring slides on the lock core, and movable the insertion in the lock body.Under lock-out state, have between lock core lock-bit ring and lock body lock-bit pellet shot from a slingshot hole one by one correspondence communicate.Lock-bit pellet shot from a slingshot hole from inside outwards is placed with lock core lock-bit pellet shot from a slingshot, lock-bit ring pellet shot from a slingshot, lock body lock-bit pellet shot from a slingshot, lock-bit spring and lock-bit pellet shot from a slingshot stopple successively.The axial displacement of lock-bit ring on lock core is subjected to the locator card restriction.Correspondingly, key has normal key and changes two kinds of keys, the both plays the effect of opening tapered end, different places show: change key the contact surface of lock core lock-bit pellet shot from a slingshot and lock-bit ring pellet shot from a slingshot is flushed with the contact surface of lock core and lock-bit ring, but the contact surface of lock-bit pellet shot from a slingshot and lock body lock-bit pellet shot from a slingshot is flushed with the contact surface of lock-bit ring and lock body, there is not pellet shot from a slingshot to stretch into mutually between lock-bit ring and lock body, the lock-bit ring is located by lock body no longer, can take out the locked lengths that the core lock changes following pellet shot from a slingshot in the pellet shot from a slingshot hole.Normal key is then just in time opposite.In order to prevent that the core lock from taking out core lock back lock-bit ring pellet shot from a slingshot and lock body lock-bit pellet shot from a slingshot drops out, on the lock-bit ring, add pellet shot from a slingshot hole shrinkage cavity cover;
