Particularly, see Fig. 4, Fig. 6, Fig. 7, the two sides of described slide block 7 are provided with sliding part 1, and sliding part 1 is arranged on the both sides of switch block 8 center of rotation, and slide block 7 is erected on a pair glide path 5013 by sliding part 1, switch block 8 and the place of being slidably connected described in sliding way 5012 are for being located at the sliding part 2 802 of switch block 8 two sides, switch block 8 is erected on a pair sliding way 5012 by sliding part 2 802, slide block 7 upper end is with a breach 702, switch block 8 is rotationally connected with the vertical walls of breach 702, the bottom of breach 702 is provided with the first confined planes 703 and the second confined planes 704 controlling switch block 8 slewing area, first confined planes 703 and the second confined planes 704 lay respectively at the both sides of switch block 8 center of rotation, further, in order to realize unlocking, sliding way 5012 is provided with the vertical spacing chute 5014 through with sliding way 5012, vertical spacing chute 5014 is located at the side of sliding way 5012 away from spring 6, when switch block 8 rotates, limit sliding chutes 5014 is spacing for sliding part 2 802.
Particularly, see Fig. 4, described vertical spacing chute 5014 is the vertical chute from sliding way 5012 to downward-extension, smooth and easy in order to lead, and vertical spacing chute 5014 is connected the place of transition with an arc guide surface with sliding way 5012.
Further, see Fig. 7, described switch block 8 is a guiding surface 803 away from one end of spring 6, and when described shifting block 4 clashes into switch block 8, the feeler 401 of shifting block 4 enters the draw-in groove 801 on switch block 8 by the guiding of guiding surface 803.
The course of work of the present invention 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 controls the slewing area of switch block 8, draw-in groove 801 horizontal positioned of switch block 8 is controlled by the sliding connection structure of the first confined planes 703, switch block 8 and 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, thus tension shifting block 4, strain interior slide rail 1 by shifting block 4, thus realize described self locking type slide rail push back state under self-locking.
1, to push back and the described self locking type slide rail of lock-out state unlocks and pull-out: need to pull open shown in Fig. 2 normally push back and described self locking type slide rail under lock-out state time, then along slide rail 1 in the axial direction pull-out of external slide rail 2, shifting block 4 together moves along with interior slide rail 1, feeler 401 due to shifting block 4 is positioned at the draw-in groove 801 of switch block 8, and switch block 8 is connected to slide block 7, therefore the axial direction of the pulling force driving switch block 8 and slide block 7 to overcome spring 6 along self-locking arm 501 is moved, wherein, switch block 8 moves along sliding way 5012, slide block 7 moves along glide path 5013, when slide block 7 moves to one end termination of glide path 5013 away from fixed arm 502, slide block 7 stops mobile under the effect of glide path 5013 termination blocking surface, now, the sliding part 2 802 of switch block 8 moves to close to described vertical spacing chute 5014, when shifting block 4 continues to be drawn out by external force, 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 (i.e. the angle of inclination of draw-in groove 801 generation) of switch block 8 is controlled by the second confined planes 704 on slide block 7, when interior slide rail 1 continues to pull outward, the feeler 401 of shifting block 4 is by the draw-in groove 801 departing from described inclination and continue to pull out until described self locking type slide rail pulls out completely, and when switch block 8 turns an angle, when described feeler 401 departs from draw-in groove 801, by vertical spacing chute 5014 block switch block 8 sliding part 2 802 thus by spacing for switch block 8 position at this rotational angle, ensure that switch block 8 and slide block 7 can not be regained by spring 6.
2, described self locking type slide rail is returned to from pull-out state the state of pushing back: the axial direction along external slide rail 2 pushes back interior slide rail 1, shifting block 4 together moves along with interior slide rail 1, when shifting block 4 moves to the position close to 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 made to enter in the draw-in groove 801 of the inclination of switch block 8, if now continue to promote interior slide rail 1, due to the effect of thrust, to be promoted by described feeler 401 and force switch block 8 to rotate around with the place of being rotationally connected described in slide block 7, thus make the sliding part 2 802 of switch block 8 leave vertical spacing chute 5014 under the guide effect of the arc guide surface of described linking transition, 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, the rotational angle of switch block 8 is limited by the first confined planes 703 on slide block 7, 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, thus make described self locking type slide rail be in self-locking state.
3, likely there will be under some artificial or non-artificial factors, when the feeler 401 of described shifting block 4 does not also enter the draw-in groove 801 of described switch block 8, switch block 8 but there occurs rotation, and retracted by spring 6 together with slide block 7, namely the position-limiting action of vertical spacing chute 5014 lost efficacy, now, by larger external force, interior slide rail 1 is pushed back, when shifting block 4 moves together along with interior slide rail 1 and clashes into switch block 8, side due to draw-in groove 801 is some guiding surfaces 803, then 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, when the position-limiting action of vertical spacing chute 5014 lost efficacy, the auto-lock process of described self-locking mechanism can be realized, ensure that self locking type slide rail of the present invention enters normal duty again.
Self locking type slide rail of the present invention is under the effect of shifting block and described self-locking mechanism, the teaching display stand locking under the state pushed back of described self locking type slide rail can be made, avoid the phenomenon that slide rail in prior art skids off voluntarily, being rotationally connected and the control of slewing area to switch block simultaneously by switch block and slide block, achieve the unlocking function of described self-locking mechanism, and by the sliding part of the vertical spacing chute on switch block slideway and switch block side by the spacing position when unlocking of switch block after unlocking, what be convenient to the follow-up slide rail of wait pushes back operation.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
