The quick locating locking mechanism, which is convenient for quick disassembly, is safe and reliable and does not fall off automatically during operation.

Description

Quick positioning locking mechanism
Technical field
The present invention relates to be used in the mechanical transmission to have the location locking mechanism between two parts of relative movement, particularly a kind of quick-detachable location locking mechanism.
Background technique
Between two parts of the relative movement in mechanical transmission, need to make it to be the no-relative motion of discontinuity sometimes, traditional way is to plug to sell directly to households between two parts to realize locating or realizing fixing by other mechanism.Though sell directly to households and can guarantee the location of mechanism on moving direction, it moves axially easily under external force and comes off, and can not guarantee the safe and reliable work of mechanism; Though fix safely by other mechanism, dismounting and installation time are long, and the cost height takes up room greatly.
Summary of the invention
The objective of the invention is to propose a kind ofly not only to be convenient to dismantle but also safe and reliable quick positioning locking mechanism, to overcome the shortcoming that traditional location locking mechanism at present exists.
Quick positioning locking mechanism of the present invention, comprise an end have the lock tube of back cover, in the lock tube inner chamber in axial sliding bearing pin, be arranged on the inconsistent stage clip in lock tube inner chamber bottom and described bearing pin left part; Be provided with the conical surface of one section necking down to the right on the right side, end that bearing pin and stage clip connect, on right-hand bearing pin of the conical surface, have the axially directed groove that connects its diameter, plant one can be along the spacing in axial sliding directional post of bearing pin in this axially directed groove, and the two ends of this directional post are set on the chamber wall of described lock tube; On the wall of the chamber of described lock tube, have two through holes of radial symmetric, in these two through holes, respectively place a shank that can be free to slide therein corresponding to the position, awl bottom of the conical surface of bearing pin.
When described shank was replaced position, awl bottom at the conical surface of bearing pin, its outer end protruded in the external diameter of described lock tube; When described shank is replaced the vertex of a cone at the conical surface of bearing pin, contract in the external diameter of described lock tube in its outer end.
The using method of quick positioning locking mechanism of the present invention is, settle at needs on two parts of relative movement of this quick positioning locking mechanism and offer a coaxial aperture, and be provided with an annular groove on the hole wall of parts in two parts of said relative movement, this quick positioning locking mechanism is inserted in the coaxial aperture on two parts, the outer end of two shanks in the location locking mechanism then is inserted in the annular groove on the hole wall of parts, can realize being locked between two parts; When the bearing pin outer end of this quick positioning locking mechanism of pushing, when bearing pin was inwardly moved axially, the outer end of two shank promptly fell in the external diameter of its lock tube, then this quick positioning locking mechanism can be extracted out from two parts, can recover the relative movement of two parts.
Adopt quick positioning locking mechanism of the present invention, both be convenient to fast quick-detach, safe and reliable again, can not come off voluntarily at work.

Embodiment
The embodiment who provides below in conjunction with accompanying drawing describes in further detail structure of the present invention.
Embodiment 1
With reference to Fig. 1,2, a kind of quick positioning locking mechanism, comprise an end have the lock tube 1 of back cover, in lock tube 1 inner chamber in axial sliding bearing pin 4, be arranged on the inconsistent stage clip 2 in lock tube 1 inner chamber bottom and described bearing pin 4 left parts; Be provided with the conical surface 41 of one section necking down to the right on the right side, end that bearing pin 4 and stage clip 2 connect, on right-hand bearing pin 4 of the conical surface 41, have the axially directed groove 42 that connects its diameter, plant one can be along the spacing in axial sliding directional post 5 of bearing pin 4 in this axially directed groove 42, and the two ends of this directional post 5 are set on the chamber wall of described lock tube 1; On the wall of the chamber of described lock tube 1, have two through holes of radial symmetric, in these two through holes, respectively place a shank that can be free to slide therein 3 corresponding to the position, awl bottom of the conical surface 41 of bearing pin 4.
Described shank 3 quilts are replaced when the position, awl bottom of the conical surface 41 of bearing pin 4, and its outer end protrudes in the external diameter of described lock tube 1; When described shank 3 is replaced the vertex of a cone at the conical surface 41 of bearing pin 4, contract in the external diameter of described lock tube 1 in its outer end.
Described shank 3 is steel ball or steel column.
As shown in Figure 3, quick positioning locking mechanism 8 of the present invention is installed on the mechanical device of forming by pedestal 7 and rotating moving part 6 to realize the quick positioning and locking of 7 of rotating moving part 6 and pedestals.With reference to Fig. 4, its specific practice is to open a coaxial aperture on rotating moving part 6 and pedestal 7, and on the hole wall of rotating moving part 6, offer an annular groove 61, this quick positioning locking mechanism 8 is inserted in the above-mentioned described coaxial aperture, the shank 3 of quick positioning locking mechanism 8 is ejected in the annular groove 61 that is stuck on rotating moving part 6 hole walls by bearing pin 4, promptly realizes the locking of this mechanical device; When needs are removed locking, as long as inwardly push from the outer end of the bearing pin 4 of quick positioning locking mechanism 8, bearing pin 4 is endwisely slipped, 3 of its shanks fall after rise with the conical surface on the bearing pin 4 41, its top breaks away from the annular groove 61 on rotating moving part 6 hole walls, can can recover the motion of rotating moving part 6 with extracting out the coaxial aperture of this quick positioning locking mechanism 8 on rotating moving part 6 and pedestal 7.
