Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
The specific embodiment of switch cubicle of the present utility model, as shown in Figure 1 to Figure 2, locks machine including cabinet 8 and valve
Structure, valve locking mechanism includes being arranged on cabinet 8 to drive upper plate 1 and the lower plate 2 of valve keying, is additionally included in handcart
It is used for locking upper and lower connecting plate so that valve is locked in closure state and after handcart pushes handcart room by when pulling out in handcart room
Release the latch-up structure of the lock-out state to upper and lower connecting plate.Fixed seat 3 that latch-up structure includes being fixedly installed on cabinet 8, lead
To the guide-rail plate 4 being movably arranged in fixed seat（I.e. movable part）And be used for driving guide-rail plate 4 along fixed seat 3 guiding movement
Portable plate 5.
The plate face of guide-rail plate 4 extends along the horizontal plane, and the right side central of guide-rail plate 4 offers the U-shaped of above-below direction insertion and opens
Mouth groove 43, U-shaped opening groove 43 makes the right side of guide-rail plate 4 define two parts of time interval setting, and rear section is bent up
Folding and define upper rail plate 41, front part bends downwards and defines lower guideway plate 42.
Upper plate 1 is articulated with the main shaft extending along the longitudinal direction with the left end of lower plate 2, and upper plate 1 is located at lower company
The front of plate 2, main shaft is set between upper plate 1 and lower plate 2 second spring 72, the two ends of second spring 72 are pushed up respectively
Pressure upper plate 1 two sides relative with lower plate 2.The left end of upper and lower connecting plate is equipped with by the push pedal institute's pushing tow on handcart and drives
Upper plate axle 11 and lower plate axle 21 that dynamic valve opens and closes, the left end of upper plate 1 offers opening towards a left side for upper rail plate 41
Right-hand member the upper limit position groove 12 that snaps in of Access Division, the left end of lower plate 2 offers opening towards a left side for the right side of lower guideway plate 42
The lower limit groove 22 that the Access Division at end snaps in.Upper limit position groove 12 and lower limit groove arranged for interval about 22, and upper and lower stopper slot exists
The groove width of above-below direction is more than the thickness in above-below direction for the corresponding upper and lower rails plate.
Vertically extending fixed plate 33 that fixed seat 3 includes being fixedly installed with respect to cabinet 8, prolong along the longitudinal direction
The train wheel bridge 32 stretched and the lower plate 31 extending along the longitudinal direction, lower plate 31 is located at the downside and between the two of train wheel bridge 32
Gap defines the guide-rail plate containing cavity that the left end for guide-rail plate 4 stretches into, and train wheel bridge 32 is bolted and is arranged at fixed plate
33 left side.
Portable plate 5 includes substantially becoming connecting lever shape, specifically includes linking arm 51 and pushing arm 52, linking arm 51 is along the longitudinal direction
Extend, the pushing arm 52 being connected to linking arm 51 rear end extends and its right-hand member is directed away from fixed plate 33 place side in left-right direction
（Increase locking mechanism floor space side）Stretch.The rear end of linking arm 51（Namely outside the connection of linking arm 51 and pushing arm 52）
It is articulated with train wheel bridge 32 by the first vertically extending jointed shaft 61, the rear end of correspondingly connected arm 51 offers confession
The first hinge hole that first jointed shaft 61 installs.The front end of linking arm 51 offers the first elongated hole 53, vertically extending
Second jointed shaft 62 passes through the left end of this elongated hole and guide-rail plate 4 to be articulated with the front end of linking arm 51 on guide-rail plate 4, and now the
One elongated hole 53 defines the second hinge hole installing for the second jointed shaft.It is connected between the front end of linking arm 51 and train wheel bridge 32
First spring 71.For ensureing that guide-rail plate 4 can the guiding shifting in left-right direction therewith when linking arm 51 rotates around the first jointed shaft 61
Dynamic, train wheel bridge 32 offers for the second jointed shaft 62 by the second elongated hole 34 of passing through and can moving in left-right direction, second
The length of elongated hole 34 is not less than the distance of guide-rail plate 4 guiding movement in left-right direction.
Fig. 1 and Fig. 2 is illustrated that the handcart of switch cubicle is under self-locking state by locking mechanism after pulling out in handcart room
Structural representation, when handcart is pushed in handcart room to the right by left end, push pedal in handcart promote the right-hand member of pushing arm 52 with
First jointed shaft 61 rotates counterclockwise for pivot center（Rotate towards direction shown in figure arrow）, now before linking arm 51
End can move through the second jointed shaft 62 to the left and drive guide-rail plate 4 to left movement, be arranged at linking arm 51 and train wheel bridge simultaneously
The first spring 71 between 32（I.e. elastic component）Can be stretched and deform upon.After handcart is advanced to setting position, upper rail
The right-hand member of plate 51 and lower guideway plate 52 is by completely out in upper limit position groove 12 and lower limit groove 22 and make upper plate 1 and lower plate
2 are unlocked by self-locking state, and now upper and lower connecting plate can be driven by handcart and take corresponding actions to drive valve to open, thus
Handcart continues propulsion and can achieve that the conduction of switch cubicle is realized in the connection of dynamic and static contact.
When handcart pulls out from right to left, push pedal on handcart releases the pushing tow to pushing arm 52, and linking arm 51 is first
Rotated clockwise with the first jointed shaft 61 for center of rotation under the return active force of spring 71, guide-rail plate 4 is in the second jointed shaft 62
Drive under move right and snap in lock upper plate 1 with lower plate 2 in corresponding stopper slot to its right-hand member, locked
Upper and lower connecting plate can not move and play the effect in closed state by valve locking, and pushing arm 52 can be with linking arm 51 simultaneously
It is clockwise to reply home position and think that next time is prepared by handcart pushing tow.In other embodiments, the first spring also may be used
To be arranged between linking arm and cabinet or between pushing arm and cabinet；Certainly, the first spring can also be arranged at connection
Compression spring between the left end of arm and train wheel bridge 32 replaces.In the case of not needing valve self-locking, valve locking mechanism is used
Lock locking.
In other embodiments：Now the portable plate of connecting lever shape can also other can be by handcart pushing tow so that lead by straight-arm etc.
Rail plate is replaced with the heterodromous drive part of handcart, as long as making linking arm and pushing arm be in that yi word pattern arrangement is in the same direction
Can；Train wheel bridge can also be saved, but setting male part or inner fovea part on the upper surface of lower plate, in the lower end of guide-rail plate
On face, setting with male part/inner fovea part shape adaptation and can snap in guide rail therein to realize guide-rail plate along the guiding shifting of fixed seat
Dynamic；For realizing guide-rail plate along the guiding movement of fixed seat it is also possible to the first hinge hole is made elongated hole, the second hinge hole make with
The hinge hole of the second jointed shaft geomery all adaptations so that by the front end of linking arm can only along hinge axes rotate and can not phase
Second jointed shaft is articulated with guide-rail plate along the bearing of trend of linking arm with moving.
The embodiment of valve locking mechanism：
The tool of valve locking mechanism in the concrete structure of valve locking mechanism of the present utility model and the embodiment of switch cubicle
Body structure is identical, specifically refers to Fig. 1 to Fig. 2, will not be described in detail herein.
