The course of work of the present utility model is as follows:
Suppose that the reset condition of described self locking type slide rail is for normally pushing back and lock-out state: see Fig. 2, the first confined planes 703 on slide block 7 is controlled the slewing area of switch block 8, draw-in groove 801 horizontal positioned by the first confined planes 703, switch block 8 with the sliding connection structure control switch block 8 of horizontal sliding way 5012, the feeler 401 of shifting block 4 is positioned at draw-in groove 801, by pulling force tension slide block 7 and the switch block 8 of spring 6, thereby tension shifting block 4, by slide rail 1 in shifting block 4 tensions, push back the self-locking under state thereby realize described self locking type slide rail.
1, to push back and described self locking type slide rail release and the pull-out of lock-out state: need to pull open shown in Fig. 2 normally push back and lock-out state under described self locking type slide rail time, along slide rail 1 in the axial direction pull-out of external slide rail 2, shifting block 4 is along with interior slide rail 1 together moves, because the feeler 401 of shifting block 4 is positioned at the draw-in groove 801 of switch block 8, and switch block 8 is connecting slide block 7, therefore the pulling force that drives switch block 8 and slide block 7 to overcome spring 6 is moved along the axial direction of self-locking arm 501, wherein, switch block 8 moves along sliding way 5012, slide block 7 moves along glide path 5013, in the time that slide block 7 moves to glide path 5013 away from the termination, one end of fixed arm 502, slide block 7 stops mobile under the effect of glide path 5013 termination blocking surfaces, now, the sliding part 2 802 of switch block 8 moves to and approaches described vertical spacing chute 5014, in the time that shifting block 4 continues to be subject to external force to be drawn out, switch block 8 enters described vertical spacing chute 5014 by rotation under the guide effect of the arc guide surface of described linking transition, switch block 8 rotates, draw-in groove 801 is tilted, the rotational angle (being the angle of inclination that draw-in groove 801 occurs) of switch block 8 is controlled by the second confined planes 704 on slide block 7, in the time that interior slide rail 1 continues to pull outward, the feeler 401 of shifting block 4 will depart from the draw-in groove 801 of described inclination and continue to pull out until described self locking type slide rail pulls out completely, turn an angle and work as switch block 8, when described feeler 401 departs from draw-in groove 801, thereby block the sliding part 2 802 of switch block 8 by vertical spacing chute 5014 by spacing switch block 8 position at this rotational angle, guarantee switch block 8 and slide block 7 can not regained by spring 6.
2, described self locking type slide rail is returned to the state of pushing back from pull-out state: push back interior slide rail 1 along the axial direction of external slide rail 2, shifting block 4 is along with interior slide rail 1 together moves, in the time that shifting block 4 moves to the position that approaches described switch block 8, now, the sliding part 2 802 of switch block 8 is limited in vertical spacing chute 5014, switch block 8 is in heeling condition, interior slide rail 1 continues to push back, the feeler 401 of shifting block 4 is entered in the draw-in groove 801 of inclination of switch block 8, if slide rail 1 in now continuing to promote, due to the effect of thrust, to promote by described feeler 401 and force switch block 8 around rotating with the place of being rotationally connected described in slide block 7, thereby make the sliding part 2 802 of switch block 8 under the guide effect of the arc guide surface of described linking transition, leave vertical spacing chute 5014, and enter horizontal sliding way 5012, thus, switch block 8 departs from the spacing of vertical spacing chute 5014, under the pulling force effect of spring 6, switch block 8 and slide block 7 will be replied toward thrust direction automatically, until interior slide rail 1, middle slide rail 3 and external slide rail 2 draw in together completely, limit the rotational angle of switch block 8 by the first confined planes 703 on slide block 7, the first confined planes 703, draw-in groove 801 horizontal positioned of the sliding connection structure co-controlling switch block 8 of switch block 8 and horizontal sliding way 5012, by pulling force tension slide block 7 and the switch block 8 of spring 6, thereby make described self locking type slide rail in self-locking state.
3, under some artificial or non-artificial factors, likely there will be, in the time that the feeler 401 of described shifting block 4 does not also enter the draw-in groove 801 of described switch block 8, but there is rotation in switch block 8, and retracted by spring 6 together with slide block 7, the position-limiting action that is vertical spacing chute 5014 lost efficacy, now, can interior slide rail 1 be pushed back by larger external force, in the time that shifting block 4 moves together and clashes into switch block 8 along with interior slide rail 1, because a side of draw-in groove 801 is some guiding surfaces 803, the feeler 401 of shifting block 4 is forced into the draw-in groove 801 of switch block 8 under the guide effect of larger External Force Acting and guiding surface 803, so, in the situation that the position-limiting action of vertical spacing chute 5014 lost efficacy, can realize the self-locking process of described self-locking mechanism, ensure that self locking type slide rail described in the utility model enters normal duty again.
Self locking type slide rail described in the utility model is under the effect of shifting block and described self-locking mechanism, can make described self locking type slide rail under the state pushing back, realize oneself's locking, avoid the phenomenon that in prior art, slide rail skids off voluntarily, being rotationally connected and the control of slewing area to switch block by switch block and slide block simultaneously, realize the unlocking function of described self-locking mechanism, and sliding part by the vertical spacing chute on switch block slideway and switch block one side is by spacing the switch block after the release position when the release, is convenient to wait for the operation that pushes back of follow-up slide rail.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of amendment.
