Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Embodiment of the present utility model is such: as shown in figures 1-4, a kind of can the extension bar of quick separating and connection, comprise front extension bar 1 and rear extension bar 2, engage locking mechanism by one between front extension bar 1 with rear extension bar 2 and be connected; Engaging locking mechanism comprises the front engagement portion be located on front extension bar 1 and the rear engagement portion be located on rear extension bar 2, and two engagement portions are suitable, rear extension bar 2 is also provided with described two engagement portions are locked spacing locking element.
In the present embodiment, front engagement portion comprises from front extension bar 1 rear end end face outward extending locating column 3 vertically, rear extension bar 2 front end is provided with the extension bar pullover 4 suitable with described locating column 3, locating column comprises is located at the first anterior cylinder, with the second cylinder being located at rear portion, in the positioning hole that after the second cylinder inserts, extension bar 2 front end is provided with; Forward and backward extension bar is located by axis hole, and the rotation centerline of locating column 3 and positioning hole overlaps, and can ensure extension bar stability very well.
The quantity that the turning surface of the first main body of locating column 3 front portion is provided with projection 31 is two, is symmetrically distributed on locating column 3, and projection 31 is in fan-shaped; The turning surface of extension bar pullover 4 is provided with a pair draw-in groove 42, this draw-in groove 42 " L " type in outer narrow inner width, and it is suitable with projection 31, the through front end to extension bar pullover 4 of this draw-in groove 42, and the front end surface of extension bar pullover 4 is open type, projection 31 can from " L " type draw-in groove 42 entering outer narrow inner width of opening, thus projection 31 coordinates with draw-in groove 42, extension bar 1 and rear extension bar 2 before axial direction restriction.The projection 31 of sector structure coordinates with draw-in groove 42, can reduce stress and concentrate, prevent front and back two extension bar from diametrically displacement occurring better, make extension bar more reliable and more stable; Front extension bar 1 and rear extension bar 2 are by the Placement of projection 31 with draw-in groove 42, and structure is ingenious, convenient and fast connection, reliable and stable, and the extension bar adapting to different size connects.
Be provided with a pair axial slide 41 corresponding with draw-in groove 42 at the outer wall of extension bar pullover 4, and axial slide 41 is suitable with described locking element; Locking element comprises a stop block 5, stop block 5 comprises the annulus 51 suitable with rear extension bar 2, annulus 51 is enclosed within rear extension bar 2, also comprise two push stopping part 52 of stretching out forward from annulus 51, push stopping part 52 inserts axial slide 41, carry out spacing to the projection 31 in draw-in groove 42, when preventing extension bar from rotating, projection 31 skids off " L " type draw-in groove 42, thus makes can transmit stable torsional interaction power between front extension bar 1 and rear extension bar 2.
And above-mentioned locking element also comprises the elastic spacing assembly be sheathed on rear extension bar 2, elastic spacing assembly comprises and is positioned at front back-up ring 9 on front side of stop block 5, is positioned at spring mechanism on rear side of stop block 5 and rear back-up ring 10.Rear extension bar 2 is provided with circular groove 7, and spring mechanism comprises the extrusion spring 6 be positioned on rear side of stop block 5 and the jump ring 8 being positioned at circular groove 7 place, and rear back-up ring 10 is arranged between jump ring 8 and extrusion spring 6 and is provided with rear back-up ring 10.Squeezing action power is dorsad provided to rear ring washer 10 and extrusion spring 6 by the jump ring 8 be fixed on circular groove 7, thus stop block 5 is pressed in axial slide 41, lock two extension bars, fast stop block 5 can also be exited axial slide 41 by front back-up ring 9, thus can the front extension bar of quick separating 1 and rear extension bar 2, structure is simple, easy to operate, the operating time of staff can be greatly reduced, increase work efficiency.
In actual use, first the locating column 3 of front extension bar 1 rear end is inserted in the positioning hole of the extension bar pullover 4 on rear extension bar 2 front end, projection 31 on locating column 3 enters beloid " L " draw-in groove 42 from the opening extension bar pullover 4, then before rotating, extension bar 1 makes the draw-in groove 42 on projection 31 and extension bar pullover 4 coordinate, thus limits the axial relative movement of forward and backward two extension bars.
Then, successively front back-up ring 9, stop block 5, extrusion spring 6, rear back-up ring 10 and jump ring 8 the other end cover from rear extension bar 2 is come in, push stopping part 52 on stop block 5 is arranged on axial slide 41, projection 31 is locked, projection 31 is made to be fixed in draw-in groove 42, prevent front extension bar 1 and rear extension bar 2 from occurring relatively rotating, then the transmitting torque by the interaction between projection 31 and draw-in groove 42; Jump ring 8 is fixed in circular groove 7, by jump ring 8, rear ring washer 10 and extrusion spring 6 are extruded, thus the annulus 51 of extrusion spring 6 pairs of stop blocks 5 is extruded, make the push stopping part 52 of stop block 5 be fixed in axial slide 41, such two extension bars just connection complete.Convenient and fast connection, structure is simple, and low cost of manufacture, can also according to actual needs, and change corresponding fit dimension and just can achieve the goal, applicability is strong.
During dismounting, only need the direction of front back-up ring 9 toward extrusion spring 6 to promote, the push stopping part 52 of stop block 5 extrudes extrusion spring 6 under the effect of front back-up ring 9, thus the push stopping part 52 of stop block 5 skids off axial slide 41; At this moment can rotate front extension bar 1, then extract front extension bar 1 from the opening of extension bar pullover 4, make projection 31 exit draw-in groove 42, thus reach the object that front extension bar 1 is separated with rear extension bar 2.Whole separation process is quick and convenient, simple to operate, substantially increases the working efficiency of operator.
Below be only preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite not departing from the utility model structure, can also make some distortion and improvement, these all can not affect effect and the practical applicability of the utility model enforcement.
