Description
Technical field
The utility model relates to a kind of baton, particularly a kind of retractable spontoon.
Background technology
Retractable spontoon is generally comprised of outer tube and the inner tube of mutual sockets more than two joints, firmly throws away inner tube in the time of use, and baton extends; While finishing using, press baton termination, the stressed retraction of inner tube, baton shortens.
No. 201220345601.2 Chinese utility model patent on February 13rd, 2013 disclosed retractable spontoon, at middle pipe and front pipe end, be provided with telescopic locking device, telescopic locking device comprises lock ball, spill locking ball-collecting rack, conical sliding block, push rod and back-moving spring, when baton stretches out, lock ball contacts with corresponding inside pipe wall extruding, reaches locking object; This utility model patent is also provided with tripper on front pipe top, tripper comprises unlock button, release spring, drive link etc., makes drive link promote to move after push rod, and then make lock ball loosening by capable of being unlocked by pressing button, front pipe will be retracted in middle pipe, thereby reaches the object of release.Aforementioned utility model unlocking manner is convenient light and handy, without firmly clashing into bulb, extended the service life of baton, its drawback is: one, and lock ball contacts with corresponding inside pipe wall extruding, can not guarantee locking, because after long-term use, lock ball is subject to frequent friction and makes sphere irregular, thus cause and inside pipe wall between frictional force diminish, easily the loosening baton that even causes is retracted; Two, unlock button draws in bulb top, in the gap that foreign material are easily jumped the queue between button and bulb, causes button stuck.
In addition, do not have the baton of handguard easily to make cutter rod saber fighting to hand, and easily make hand depart from handle and slide to body, safety coefficient is extremely low; For this reason, have technology at handle place, to fix a handguard, palette knife or rod during along the parallel direction saber fighting of handguard, still can be attacked hand.
Utility model content
The utility model, for addressing the above problem, provides a kind of retractable spontoon.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
A kind of retractable spontoon, comprise outer tube, middle pipe, inner tube, bulb, the anticreep collar, lock ball, spill locking ball-collecting rack, conical sliding block, it is characterized in that: bulb sidewall outer cover has release torsion circle, bulb inner chamber has cross solution lock, and cross release column bottom is connected with drive link; Bulb bottom is screwed in inner tube top; On release torsion circle outer wall, be evenly equipped with concave and convex stripe.
Bulb inner chamber is tubular, and chamber wall has penetrating tipper; Release torsion circle inwall has the Baltimore groove of inclination; Baltimore groove is corresponding with the position of tipper, and angle of inclination is consistent.
The transverse ends of cross solution lock is stretched out bulb chamber wall by tipper, and is clipped in the Baltimore groove of release torsion circle inwall.
The inwall of outer tube is fluted, and there is step on inwall top; The anticreep collar and outer tube wall top spin, gapped between the bottom of the anticreep collar and outer tube wall step.
On conical sliding block, have rectangle projection, aforementioned rectangle projection is positioned at the groove of outer tube wall.
The structure of middle inside pipe wall is consistent with outer tube wall structure.
On the outer wall of outer tube, be socketed with the first handguard, on the first handguard, have annular projection, on annular projection, movable sleeve is connected to the second handguard, and annular projection top is connected with retainer ring.
The first handguard is pushed up and is compressed admittedly on outer tube by screw.
The annular projection outer wall level of the first handguard is evenly equipped with sphere pit.
On the second handguard, have through hole, through hole inside has steel ball, spring, the second screw from the annular projection of the first handguard successively to the second handguard left end; The structure of through hole inside from the first handguard annular projection to the second handguard right-hand member is consistent with the second handguard left end.
Adopt technique scheme, spring top is pressing steel ball at the annular projection outer wall extrusion rolling of the first handguard, while running into sphere pit, steel ball is headed into sphere pit under elastic force effect, thereby the positioning action of playing, now needs firmly to rotate the second handguard, just can make the second handguard continue rotation.360 °, axle center rotation the second handguard along the first handguard, often runs into sphere pit and is just positioned, then exert oneself, continue to rotate again, and so forth, until the second handguard rotation is positioned to the position needing; While not using baton, the second handguard rotation is navigated to the position overlapping with the first handguard, dwindle baton volume, be easy to carry or preserve.Because the second handguard can form and intersect with the first handguard in rotation, so compare with single handguard, can prevent better that cutter rod saber fighting is to hand.
Due to all gapped between the bottom of the anticreep collar and outer tube, middle inside pipe wall step, when baton stretches out, a part of extrusion of lock ball, in gap, can play the object of axial location; A plurality of lock balls form a circumference in aforementioned gap, because aforementioned circumference overall diameter is greater than the inner diameter of contacted pipe, thus can play suspension effect, rather than rubbing action.Therefore, the technical scheme that relies on frictional force realization locking with prior art is compared, and locking effect of the present utility model is more reliable and more stable, even lock ball is subject to being out of shape after long-term friction, also can not affect suspension.
In the process of stretching out, the rectangle projection on conical sliding block slides along the groove of respective tube inwall, thereby realizes the radially spacing object to respective tube.
Bulb, release torsion circle, cross solution lock, drive link have formed a tripper, in the time of need to bouncing back baton, turn release torsion circle, the Baltimore groove of release torsion circle inwall drives the rotation of cross solution lock, and the tipper on bulb, again further for cross solution lock provides swing-around trajectory, moves down cross solution lock simultaneously, and then the conical sliding block on promotion transmission masthead pressure stretch contracting locking device, lock ball is retracted, and suspension effect disappears, and realizes retraction object.Compared with prior art, release torsion circle has played parcel, protective effect, makes tripper not be subject to foreign material and stops up.
The utility model is rational in infrastructure, and locking effect is reliable and stable, convenient for unlocking, and maintenance rate is low, durable in use, and has strengthened the protection of hand, for user provides safety guarantee.
