The utility model solves the technological scheme that its technical problem adopts:
A kind of pin pipe locking mechanism, comprise the first body, be located in the first body and can be along the first body the second body and can lock the first body and the rotary-tightening device of the second body in axial sliding, also be arranged with a upper cover on described the first body, and this upper cover can be installed and is fixed to the rotary-tightening device upper end.
Described upper cover is arranged on the rotary-tightening device upper end by screw-thread fit.
Described rotary-tightening device comprises and is arranged on the first body lower end and disposes internal thread the lock sleeve that can be connected with the connecting sleeve screw-thread fit and the gripping sleeve that is arranged on the lock sleeve lower end with externally threaded connecting sleeve,, offer some breach on described gripping sleeve, make this gripping sleeve can be connected the cover extruding and compress locked the second body.
Described gripping sleeve is provided with tilted conical surface on the outside, and described connecting sleeve lower end is provided with pushing surface in the wedge shape corresponding with tilted conical surface.
Described lock sleeve inwall is provided with lug boss, is provided with the inner groovy corresponding with lug boss on described gripping sleeve, and described gripping sleeve is equipped with on lock sleeve by inner groovy and lug boss.
Described upper cover lower end is provided with the upper cover outside thread, and described lock sleeve upper end inwall is provided with the upper internal threaded corresponding with the upper cover outside thread.
Be arranged with Anti-slip cover on described lock sleeve.
Described upper cover is provided with the boss that internal diameter is less than connecting sleeve external diameter, by this boss, can limit the slide displacement of connecting sleeve in lock sleeve.
Described upper cover upper end is provided with inclined-plane.
Described upper cover is made by aluminum material.
The beneficial effects of the utility model are: in the rotary-tightening device upper end, one upper cover is installed, can play preferably good sealing and dustproof effect to rotary-tightening device by this upper cover, this upper cover does not affect the rotation of rotary-tightening device simultaneously, make the operation of rotary-tightening device simple and easy higher, and the structure of rotary-tightening device compactness more, beautiful shape.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is decomposing schematic representation of the present utility model;
Fig. 3 is generalized section of the present utility model;
Sectional drawing when Fig. 4 is connecting sleeve of the present utility model, lock sleeve, gripping sleeve decomposition.
Embodiment
Referring to figs. 1 through Fig. 4, Fig. 1 to Fig. 4 is the structural representation of a specific embodiment of the utility model, as shown in the figure, a kind of pin pipe locking mechanism, comprise the first body 1, be located in the first body 1 and can be along the first body 1 the second body 2 and can lock the rotary-tightening device 3 of the first body 1 and the second body 2 in axial sliding, described rotary-tightening device 3 comprises and is arranged on the first body 1 lower end and with the connecting sleeve 31 of outside thread 311, one lock sleeve 32 that disposes internal thread 321 and be connected with connecting sleeve 31 screw-thread fit, and be arranged on the gripping sleeve 33 of lock sleeve 32 lower ends, offer some breach on described gripping sleeve 33, described gripping sleeve is provided with tilted conical surface 331 on 33 outsides, described connecting sleeve 31 lower ends are provided with pushing surface 312 in the wedge shape corresponding with tilted conical surface 331, described lock sleeve 32 inwalls are provided with lug boss 322, be provided with the inner groovy corresponding with lug boss 322 332 on described gripping sleeve 33, described gripping sleeve 33 is equipped with on lock sleeve 32 by inner groovy 332 and lug boss 322, while needing locking, screw in lock sleeve 32, make lock sleeve 32 move up under the mating reaction of internal thread 321 and outside thread 311, gripping sleeve 33 moves up under the drive of lock sleeve 32, now, tilted conical surface 331 on gripping sleeve 33 outsides compresses mutually with the interior pushing surface 312 of the wedge shape of connecting sleeve 31 lower ends, because having barbed portion, gripping sleeve 33 there is certain elasticity, therefore being compressed, gripping sleeve 33 clamps the second body 2, thereby realize locking the first body 1 and the second body 2, in the time of need to unclamping, oppositely screwing out lock sleeve 32 gets final product, in order to facilitate turn lock sleeve 32, also be arranged with an Anti-slip cover 34 on lock sleeve 32.
As shown in the figure, also be arranged with a upper cover 4 on the first body 1, described upper cover 4 lower ends are provided with upper cover outside thread 41, described lock sleeve 32 upper end inwalls are provided with the upper internal threaded corresponding with upper cover outside thread 41 323, therefore this upper cover 4 can be arranged on lock sleeve 32 upper ends by screw-thread fit, can be to 3 of rotary-tightening devices good sealing and dustproof effect preferably by this upper cover 4, this upper cover 4 does not affect the rotation of rotary-tightening device 3 simultaneously, make the operation of rotary-tightening device 3 simple and easy higher, and in the present embodiment, upper cover 4 is made by aluminum material, its upper end is provided with inclined-plane, make structure of the present utility model compactness more reliable, and beautiful shape.
In addition, as shown in the figure, described upper cover 4 is provided with the boss 42 that internal diameter is less than connecting sleeve 31 external diameters, can limit the slide displacement of connecting sleeve 31 in lock sleeve 32 by this boss 42, while making upper cover 4 locking, connecting sleeve 31 can only be unscrewed and can't be screwed out, and prevents that connecting sleeve 31 from coming off and causing locking device 3 to lose efficacy, and reliability is higher.
Above better enforcement of the present utility model is illustrated; certainly; the utility model can also adopt form different from the embodiment described above; the conversion be equal to that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or corresponding the change, all should belong in protection domain of the present utility model.
