Embodiment
Be described in further detail the utility model below in conjunction with drawings and Examples, the direction of arrow wherein in Fig. 3 ~ Fig. 9 represents the moving direction of self-locking member.
Referring to figs. 1 through Fig. 9, a kind of self-locking mechanism of the present utility model, comprises fixing frame 1 and self-locking member 2, and described fixing frame 1 is installed on ceiling board, and it is rotatably mounted with connecting sheet 11, and connecting sheet 11 lower end is provided with peg 111; described self-locking member 2 is installed on module, the special-shaped slot 21 of upper end open is provided with in it, special-shaped slot 21 lower end is provided with the first restraining groove 211 and the second restraining groove 212, lock dog 22 is provided with in special-shaped slot 21, be formed for guiding peg 111 to enter and through the first restraining groove 211 from opening between lock dog 22 periphery and special-shaped slot 21 inwall, again from the guide channel 23 that opening is deviate from after second restraining groove 212, guide channel 23 shape ringwise, lock dog 22 lower end is provided with the screens groove 221 coordinated with peg 111, described lock dog 22 stretches into the first restraining groove 211 upper area near the side of the first restraining groove 211 and is provided with in this lower end, side and can peg 111 be guided when self-locking member 2 down moves to enter the first lock dog guide surface 222 of screens groove 221, protruding 213 are formed between described first restraining groove 211 and the second restraining groove 212, described screens groove 221 can from screens groove 221 fall into second restraining groove 212 to make peg 111 when self-locking member 2 up moves at described protruding 213 and second upper areas between restraining groove 212.In the present embodiment, connected by rotating shaft between described connecting sheet 11 and fixing frame 1 and can realize relatively rotating, in order to the angle of swing of connecting sheet 11 being controlled in special-shaped slot 21 dimensional range, described fixing frame 1 is provided with connecting sheet spacing hole 112, and described connecting sheet 11 is provided with the bounding means 12 coordinating to limit connecting sheet 11 angle of swing with connecting sheet spacing hole 112.Described bounding means 12 can disperse the active force of connecting sheet 11 countershaft, extends working life of the present utility model.
When the utility model is installed, first by peg 111 rough alignment of self-locking member 2 with connecting sheet 11, then upwards lifting module, the self-locking member 2 be installed on module moves upward thereupon, peg 111 can enter the first restraining groove 211 along guide channel 23, and then slowly loose one's grip, module drives self-locking member 2 to move down under gravity, peg 111 can enter screens groove 221 along the first lock dog guide surface 222 and mount with screens groove 221, and at this moment self-locking mechanism completes installation.During dismounting, above lift module, self-locking member 2 is up moved, peg 111 can enter the second restraining groove 212 along guide channel 23, then slowly loose one's grip, module drives self-locking member 2 to move down under gravity, and now peg 111 can finally deviate from special-shaped slot 21 along guide channel 23 is up mobile.
Conveniently guide peg 111 in guide channel 23, press desired trajectory motion, described lock dog 22 upper end is provided with the second lock dog guide surface 223 that can peg 111 be guided down to move when self-locking member 2 up moves, described second lock dog guide surface 223 near the side of the second restraining groove 212 higher than its near the side of the first restraining groove 211 to guide peg 111 to enter the first restraining groove 211.Described lock dog 22 is provided with the 3rd lock dog guide surface 224 that can peg 111 be guided up to move when self-locking member 2 down moves near one end of the second restraining groove 212.Described special-shaped slot 21 is provided with the peg 111 that can guide when self-locking member 2 up moves connected with the first restraining groove 211 and enters the first restraining groove guide surface 214 of the first restraining groove 211.Described special-shaped slot 21 is provided with the peg 111 that can guide when self-locking member 2 up moves connected with the second restraining groove 212 and enters the second restraining groove guide surface 215 of the second restraining groove 212.In the present embodiment, the first described lock dog guide surface 222, second lock dog guide surface 223, the 3rd lock dog guide surface 224, first restraining groove guide surface 214, second restraining groove guide surface 215 are inclined-plane.
Conveniently guide peg 111 to move downward, the opening of described special-shaped slot 21 is up big and down small horn mouth, and described horn mouth is provided with the first inclined-plane 201 and the second inclined-plane 202 respectively near the second restraining groove 212 and the first restraining groove 211.Further, the gradient on described first inclined-plane 201 is less than the gradient on the second inclined-plane 202, effectively can ensure peg 111 no matter along the first inclined-plane 201 or the second inclined-plane 202 enters special-shaped slot 21, all can move to the first restraining groove 211 and the second restraining groove 212 can not be fallen into, ensureing to be in place.The bottom on described first inclined-plane 201 is higher than the bottom on the second inclined-plane 202, effectively can ensure that peg 111 can enter opening smoothly from the second restraining groove 212 when guide channel 23 up moves, and the another side of guide channel 23 can not be fallen at guide channel 23 Inner eycle, ensure that dismounting puts in place.
Further, the friction plate for preventing connecting sheet 11 from rotating under self gravitation is provided with between described fixing frame 1 and connecting sheet 11.Described friction plate increases the frictional force between fixing frame 1 and connecting sheet 11, even if when peg 111 is down moved from screens groove 221 depart from desired trajectory also can not because of connecting sheet 11 self gravitation cycle state vertically downward, but the angle state remained on when departing from desired trajectory, so can slowly loose one's grip allows self-locking mechanism down move under gravity, thus makes push rod automatically up walk to deviate from self-locking mechanism along guide channel 23.
In the present embodiment, in order to simplify the internal structure of an organization, described connecting sheet 11 and peg 111 one-body molded, certainly, in order to reduce the friction between peg 111 and guide channel 23 inwall, peg 111 is moved more smooth and easy, described peg 111 also can be installed on connecting sheet 11 rotationally.
All features disclosed in this specification, or the step in disclosed all methods or process, except the feature mutually repelled and/or step, all can combine by any way, unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object, namely, unless specifically stated otherwise, each feature is an embodiment in a series of equivalence or similar characteristics.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
