[embodiment]
Below in conjunction with accompanying drawing, the utility model is further described:
Embodiment 1:
As Fig. 1, Fig. 4, Fig. 7, shown in Fig. 8, a kind of locking device, comprise sleeve pipe 1 and be located at the inner tube 2 in described sleeve pipe 1, in described inner tube 2, be provided with the latch 3 that can make itself and the 1 relative position locking of described sleeve pipe, described latch 3 comprises the lock bracket 31 being located in described inner tube 2, described lock bracket 31 is provided with its clamping block laterally sliding 32 relatively, on described inner tube 2 and described sleeve pipe 1 tube wall, be respectively equipped with interior pipe through-hole 201 and sleeve through hole 101, described clamping block 32 be provided with when it laterally slides can be with it stop pin 33 in interior pipe through-hole 201 and sleeve through hole 101 interior slips, on described clamping block 32, be also provided with inclination bar hole 34, thereby in described inner tube 2, be provided with in described inclination bar hole 34, to slide and promote the drive unit 35 that described clamping block 32 laterally slides.In sleeve pipe 1 and inner tube 2, be respectively equipped with sleeve through hole 101 and interior pipe through-hole 201, lock bracket 31 in inner tube 2 is provided with the clamping block 32 that lock bracket 31 laterally slides relatively, stop pin 33 on clamping block 32 can penetrate or exit sleeve through hole 101 when clamping block 32 laterally slides, when stop pin 33 exits from sleeve through hole 101, sleeve pipe 1 completes release with 2 of inner tubes.Clamping block 32 is provided with the inclination bar hole 34 of inclination, drive unit 35 can slide in inclination bar hole 34, drive unit 35 just promotes clamping block 32 and laterally slides in the process sliding, once clamping block 32 laterally slides, stop pin 33 just can penetrate or exit sleeve through hole 101.The utility model is simple in structure, easy to operate, reliable, can be from sleeve pipe 1 internal drive sleeve pipe 1 and inner tube 2 releases or locking, avoided traditional needs pressing lock rationed marketing from the outside 33 and the inconvenience that brings.
As shown in Figure 3, described drive unit 35 comprise through described clamping block 32 and described lock bracket 31 and can be relative the two at the interior slide plate sliding up and down 352 of described inner tube 2, described slide plate 352 middle parts are provided with stretches into the pushing pin 353 that in described inclination bar hole 34 and when described slide plate 352 slides, the described clamping block 32 of promotion laterally slides, described slide plate 352 one end are provided with block 354, between described block 354 and described lock bracket 31, be provided with and can make described slide plate 352 slide the Returnning spring 355 of reset, in described inner tube 2, be provided with can drive that described slide plate 352 slides slide drive unit 356.The line of travel of slide plate 352 can be determined according to the true dip direction of inclination bar hole 34, when the more close stop pin 33 in Bi Qi lower end, the upper end of inclination bar hole 34 (as shown in Figure 3), if make slide plate 352 upwards slide sleeve pipe 1 and inner tube 2 releases; If during Bi Qi upper end, the lower end more close stop pin 33 of inclination bar hole 34, if make slide plate 352 slide downwards sleeve pipe 1 and inner tube 2 releases.Need to be by inner tube 2 during with sleeve pipe 1 release, sliding drive unit 356 drives slide plate 352 to slide, slide plate 352 is when upwards sliding, the pushing pin 353 at its middle part contacts with the hole wall of inclination bar hole 34,353 of pushing pins promote clamping block 32 and move right, and now, stop pin 33 just exits in sleeve through hole 101, sleeve pipe 1 completes release with inner tube 2, and 2 of inner tubes can slide up and down sleeve pipe 1 is interior.At clamping block 32, move right, after sleeve pipe 1 and inner tube 2 releases, the end of stop pin 33 withstands on the inwall of sleeve pipe 1, the hole wall of the bar hole 34 that tilts is kept out pushing pin 353, now Returnning spring 355 is in compressive state.When if sleeve pipe 1 inner tube 2 need to be locked, pull or promote inner tube 2, when 101 pairs of stop pin 33 and sleeve through holes punctual, Returnning spring 353 by compression plays a role, slide plate 352 moves downward, pushing pin 353 promotes clamping block 32 to left movement, in stop pin 33 threading through holes 101, completes the locking of sleeve pipe 1 and inner tube 2.
As shown in Figure 2 and Figure 3, described drawing slided drive unit 356 and is connected and can supplies the cable wire of drawing for slide plate 352 the other ends with described.When cable wire is during by drawing, cable traction slide plate 352 moves upward, thereby completes the release of sleeve pipe 1 and inner tube 2.
As shown in Figure 5, Figure 9, described lock bracket 31 is provided with cross groove 312 and vertical groove 313, and described clamping block 32 is located in described cross groove 312, and described block 354 and described Returnning spring 355 are located in described vertical groove 313.
As shown in Fig. 6, Fig. 9, described lock bracket 31 is provided with the bar hole 314 communicating with described inclination bar hole 34, and described pushing pin 353 penetrates in described bar hole 314 and can slide up and down within it.
As shown in Figure 3, thus in described inner tube 2, be provided with and can keep out the limit stoper 4 that described block 354 limits described slide plate 352 reset positions.When there is no limit stoper 4, effect due to Returnning spring 355, pushing pin 353 pushes up the lower end of inclination bar hole 34 always, and clamping block 32 is produced to downward pressure, at this moment stop pin 33 can, to pressing down sleeve through hole 101 and interior pipe through-hole 201, easily cause sleeve through hole 101 and 201 distortion of interior pipe through-hole.Be provided with after limit stoper 4, limit stoper 4 can withstand block 354, make the pushing pin 353 at slide plate 352 and middle part thereof rest on an appropriate position, make stop pin 33 roughly penetrate in the centre of sleeve through hole 101 and interior pipe through-hole 201 and can not produce pressure to the two.
As shown in Fig. 2, Fig. 4, Fig. 5, Fig. 9, described limit stoper 4 comprises the spacing hole 41 being located on described inner tube 2 tube walls and is located at the bracket holes 42 in described lock bracket 31, in described spacing hole 41 and described bracket holes 42, is provided with position limit pin 43.
Embodiment 2:
Embodiment 2 is with embodiment 1 difference:
As shown in figure 10, thus the described drive unit 356 that slides comprise and be located at described block 354 1 sides and can promote the push rod that the slide plate 352 described in 354 promotions of described block slides.Push rod promotes block 354, and 352 of slide plates slide in inner tube 2, and 353 of pushing pins promote clamping block 32 and slide, thereby completes the release of sleeve pipe 1 and inner tube 2.
Embodiment 3:
Embodiment 3 is with the difference of implementing 2:
As Figure 11, shown in Figure 12, described sleeve pipe 1 is provided with ferrule openings groove 102, described sleeve through hole 101 is located at the bottom land of described ferrule openings groove 102, described inner tube 2 is articulated with in described ferrule openings groove 102, the support bar hole 316 that described lock bracket 31 is provided with groove 315 and communicates and supply described pushing pin 353 to slide up and down with described groove 315, described clamping block 32 is located in described groove 315, described limit stoper 4 comprises the U-shaped groove 43 being located on described block 354, described inner tube 2 is provided with the position-limited lever 44 that penetrates described U-shaped groove 43.In the present embodiment, inner tube 2 is articulated with in the ferrule openings groove 102 of sleeve pipe 1, and after sleeve pipe 1 and inner tube 2 releases, inner tube 2 can complete and rotate relative to sleeve pipe 1.The present embodiment can be applied to the occasion that needs inner tube 2 to rotate after sleeve pipe 1 and inner tube 2 releases.
As shown in figure 12, described lock bracket 31 is provided with the circular groove 317 inserting for described Returnning spring 355, and described block 354 is provided with the boss 3541 inserting in described Returnning spring 355.Returnning spring 355 inserts circular grooves 317 and boss 3541 and snaps in the displacement that Returnning spring 355 can prevent Returnning spring 355 when interior.
