Embodiment
Understand for technical characterictic, purpose and effect to invention have more clearly, contrast description of drawings embodiment of the present invention at present, identical label is represented the identical or structural similarity of structure but the identical part of function in each figure.
Fig. 2 is the perspective view of a kind of exemplary embodiment of locking mechanism of switching device shifter.As shown in the figure, the locking mechanism of switching device shifter comprises: an operating parts 20 and a locking piece 30.Wherein operating parts 20 is installed in the switching device shifter (not shown), and the rotation of operating parts 20 can realize switching on and off of switching device shifter, and 30 of locking pieces can be used for restriction operation spare 20 and rotate.Locking piece 30 can along vertical and operating parts 20 rotation axiss to direction on slide (shown in arrow in scheming), locking piece 30 is along being provided with first sticking department 32 on its glide direction.Upwards being provided with second sticking department, 22, the first sticking departments 32 week of operating parts 20 can be mutually nested with second sticking department 22, with the rotation of restriction operation spare 20.
Fig. 3 is the cross-sectional schematic along III-III line among Fig. 2.As shown in the figure; In the needs latched position, locking piece 20 slides along the direction shown in the arrow among the figure from the position shown in the dotted line; Be nested in second sticking department 22 that upwards is provided with in week of operating parts 20 until first sticking department 32 of locking piece 30, thereby with the rotation of restriction operation spare 20.
Though in Fig. 2 and execution mode shown in Figure 3; The circumferential position of second sticking department 22 position of the connection on operating parts 20 sign 24 just is corresponding; Like this; When operating parts 20 control switch device were connected, first sticking department 32 can be nested in second sticking department 22, so that the rotation of restriction operating parts 20 when switching device shifter is in on-state.
It will be appreciated by those skilled in the art that; Operating parts can also be provided with a plurality of second sticking departments are set respectively; Correspond respectively to the different switching positions of switching device shifter; When needs lock corresponding switching position, only need rotating operation spare, make first sticking department of locking piece can be nested into second sticking department corresponding with corresponding switching position.
Fig. 4 is the perspective view of the another kind of exemplary embodiment of locking mechanism of switching device shifter.First sticking department 32 among the figure is the locking boss, and second sticking department 22 is a lock hole.As shown in the figure, in order to reduce locking piece 30 along the axial size of operating parts 20, locking piece 30 is a laminated structure.Locking piece 30 middle parts are provided with an installing hole 34, and operating parts 20 can be located in the installing hole 34 of locking piece 30, and locking boss 32 is arranged on the inner peripheral surface of installing hole 34.In exemplary embodiment shown in Figure 4, installing hole 34 is a square hole.
Those skilled in the art is further appreciated that assembly hole can also be to remove other square shapes, and is for example circular, polygon etc., but the shape of assembly hole must not hinder the insertion of operating parts and the rotation of operating parts.Locking boss simultaneously can be arranged on the operating parts, and correspondingly lock hole is arranged on the locking piece, and the situation that the locking boss is set respectively on operating parts and the locking piece.
In the exemplary embodiment as shown in Figure 4; Be provided with padlock hole 36 with locking boss 32 relative ends, behind the drop-down locking piece 30 of operator, locking boss 32 just inserts in the lock hole 22; In order to prevent that locking piece from resetting, padlock 60 (not drawing among the figure) is set in the padlock hole simultaneously.Should be appreciated that, here " on ", D score only is used to represent the position relation between the relevant portion, and non-limiting their absolute position.Can in the padlock hole, be provided with many as required padlock.
In addition; In exemplary embodiment shown in Figure 4; Locking mechanism also comprises two shell fragment 40a and 40b; Locking piece 30 is respectively equipped with groove 38 on two sides that parallel with its glide direction, the end of shell fragment 40a and 40b inserts respectively in the groove 38, and the other end then can be separately fixed in the switching device shifter and (hold the back in detail).
It will be understood by those skilled in the art that the purpose that shell fragment is set is for the locking piece that is in the lock state is resetted.Simultaneously, shell fragment can support locking spare under unlock state, prevents that its gravitate from inserting in lock hole, when needs operational lock spare, when making its locking boss insert lock hole, need overcome the elastic force of elastic component.
Fig. 5 is to use the perspective view of a kind of exemplary embodiment of switching device shifter of the locking mechanism of switching device shifter; Only schematically dotted the profile of the body 50 of switching device shifter among the figure; Only be used to explain locking mechanism and body 50 correlations, and do not represent the practical structures and true ratio of switching device shifter.As shown in the figure, switching device shifter comprises body 50 and locking mechanism (not identifying among the figure).Wherein, locking mechanism comprises operating parts 20 and locking piece 30, and body 50 is provided with assembly hole 52, and the operating parts 20 of locking device can axially be installed in the body 50 along it.
As shown in Figure 5, if locking mechanism also is provided with two flexure strip 40a and 40b, then the end of shell fragment 40a and 40b inserts respectively in the groove 38, and the other end is separately fixed in the body 50.
Fig. 6 to 7 has explained the locking process of the switching device shifter that is to use the invention locking mechanism.First sticking department 32 among the figure is the locking boss, and second sticking department 22 is a lock hole.
Fig. 6 is the partial structurtes sketch map that is in unlock state.As shown in the figure; The end of shell fragment 40a and 40b is separately fixed in the body 50; The other end inserts respectively in the groove 38 and (has only schematically identified one of them among the figure), and the locking boss 32 of locking piece 30 is not inserted in the lock hole 22 and (does not identify among the figure), and this moment, switching device shifter was in on-position; When needs lock operation spare, press the drop-down locking piece 30 of the direction of arrow shown in Fig. 6.As shown in Figure 7; When the locking boss (not shown) of locking piece 30 is inserted lock hole (not identifying among the figure); Shell fragment 40a and 40b produce distortion as shown in Figure 8, reset for the locking piece that prevents to be in the lock state simultaneously, and padlock 60 is set in padlock hole 36.
It will be appreciated by those skilled in the art that; Behind the padlock in the part padlock hole that unlocks; And there is not downward external force restriction locking piece; Locking piece will automatically revert to the locking piece position shown in Fig. 6 under the resilient force of shell fragment, opposite by the motion process of describing among the motion process that locks state to unlock state and Fig. 6 to Fig. 7, repeat no more at this.
Use the locking mechanism and the switching device shifter thereof of switching device shifter; Through being set, locking piece on the direction axial, operating parts is locked perpendicular to operating parts; The switching device shifter that has reduced locking mechanism is housed makes the switching device shifter that locking mechanism is housed to be installed in and installs in the less cabin body of depth in the size that the depth direction is installed.
Use the locking mechanism and the switching device shifter thereof of switching device shifter, simple in structure, use part few, maintenance and replacing locking mechanism are convenient.
