State.The two-way world latch structure that the utility model is provided is simple, is hardly damaged, and service life length, reliability are high.
Brief description of the drawings
, below will be right in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
The accompanying drawing used required in embodiment or description of the prior art is briefly described.In all of the figs, it is similar
Element or part are general by similar reference mark.In accompanying drawing, each element or part might not be according to actual ratios
Draw.
The structural representation for the two-way world latch that Fig. 1 provides for an embodiment；
The principle schematic for the two-way world latch that Fig. 2 provides for an embodiment.
Embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.Following examples are only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality can not be limited with this
New protection domain.
Fig. 1 is the explosive view of two-way world latch, and Fig. 2 is the principle schematic of two-way world latch, wherein rotating shaft along arrow
Head direction is rotated, and from locked state S1, by intermediate state S2, switches to released state S3.
It should be noted that unless otherwise indicated, technical term or scientific terminology used in this application should be this reality
The ordinary meaning understood with new one of ordinary skill in the art.
Referring to Figures 1 and 2, in an embodiment, the two-way world latch that the utility model is provided, including：Base 110, turn
Axle 210 and bolt mechanism；Sliding way and glide path are vertically provided with the base 110, the rotating shaft 210 is set
Put on the base 110, and positioned between the sliding way and the glide path；The sliding way and the glide path are fitted
Equipped with a bolt mechanism；Each bolt mechanism includes connecting rod 220, sliding block 230 and latch 240, the connecting rod
220 one end is hinged with the rotating shaft 210, and the other end is hinged with the sliding block 230, and the sliding block 230 is slidably connected at accordingly
Slideway on, the rotating shaft 210, connecting rod 220 and sliding block 230 composition slider-crank mechanism.
The two-way world latch 240 that the present embodiment is provided, two divertimentos are constituted by rotating shaft 210 and two mechanisms of latch 240
Handle slide block mechanism, each sliding block 230 is connected with a corresponding latch 240.When being rotated as the rotating shaft 210 of crank, two are driven
Individual sliding block 230 is moved back and forth simultaneously on slideway, and because two slideways are symmetrical arranged with respect to rotating shaft 210, two sliding blocks 230 are reverse
Action, so that superposed latch 240 and the latch 240 positioned at bottom, while inserting corresponding pin-and-hole into sealed shape
State, or the abjection from pin-and-hole simultaneously, into released state.The two-way world latch 240 is simple in construction, and small volume only needs very little
Cavity space can install, and be hardly damaged, service life is long.
Specifically, the length in order to expand crank, extends and is coaxially provided with the sliding distance of sliding block 230, the rotating shaft 210
Adpting flange 211, the connecting rod 220 being adapted to sliding way is hinged with the flange in the first hinge, the company being adapted to glide path
Extension bar 220 is hinged with the flange in the second hinge.
Meanwhile, first hinge and the relatively described axial symmetry of rotating shaft 210 of second hinge are set, when the two-way day
When ground latch 240 is in locked state, first hinge is in the upper end of the rotating shaft 210, when the two-way world latch
240 be in released state when, first hinge be in the rotating shaft 210 lower end.So that the sliding distance of sliding block 230 reaches
To maximum, with two hinges directly apart from equal.And set by axial symmetry so that two synchronization actions of sliding block 230, together
When be unlocked or sealed.
When further, in order to prevent that crank from rotating, interfere with rotating shaft 210, the connecting rod 220 is provided with the groove of C-shaped,
And when the two-way world latch 240 is in released state, the rotating shaft 210 is located in the groove of the connecting rod 220.
Acted because the present embodiment rotates driving latch 240 by rotating shaft 210, if rotational angle is excessive or deficiency,
Latch 240 can be caused to depart from optimal sealed or unlocked position.Therefore, the two-way world latch 240 originally implemented also includes setting
Gag lever post 310 on base 110, the edge of the adpting flange 211 is provided with the first limiting section and the second limiting section 321, when
When the two-way world latch 240 is in locked state, first limiting section is adapted to the gag lever post 310, when described double
When being in released state to world latch 240, second limiting section 321 is adapted to the gag lever post 310.So as to prevent rotating
Angle is excessive or deficiency.Specifically, above-mentioned gag lever post 310 is elastic rod, first limiting section and second limiting section 321
It is limited impression.When rotating shaft 210 is rotated, the edge of elastic rod and adpting flange 211 is interference fitted, and is reached after limited impression,
Elastic rod is caught in limited impression, while playing damping.
Operate for the convenience of the users, the two-way world latch 240 of the present embodiment also includes what is be connected with the rotating shaft 210
Handle 400.The arm of force is increased by handle 400, facilitates rotating shaft 210.
Specifically, also including the cover plate 120 being detachably connected with base 110 in originally implementing.
