Embodiment
The embodiment of interlock degree of depth measurer of the present invention: as Figure 1-5, comprise positioning tube 3 and gage 2, positioning tube 3 is the adaptive cylindrical structure in contact arm 11 that is inserted into, the removable annular end cap 5 that is installed with of its right-hand member, gage 2 is axially inserted in positioning tube 3 from right to left, its left section is scale section 21, on the forward and backward side wall surface of scale section 21, is marked with size scale.The outer peripheral face of the outstanding positioning tube 3 of the outer rim of end cap 5, when positioning tube 3 adaptations are inserted into contact arm 11 when interior, end cap 5 is positioned at Mume flower contact 12 like this, and its outshot plays the effect to left limit, and the while left side of end cap outer rim outshot is positioning reference plane; The inner edge of end cap 5 is the inner peripheral surface of outstanding positioning tube 3 inwardly, and the left side of end cap inner edge outshot is the limit block face to right limit to gage 2; Right-hand member axial location at gage 2 is fitted with pushing tow rod 6, pushing tow rod 6 be gage 2 for the pushing part with static contact 13 apical graftings, and pushing tow rod 6 has the adaptive inserting section with end cap endoporus adaptation, adaptive inserted terminal inserts end cap endoporus left during pushing tow gage 2 at pushing tow rod 6.
On positioning tube 3 inner peripheral surfaces, convex with the annular boss 10 passing for gage 2, in positioning tube 3, be positioned at boss 10 leftward position place envelopes and be provided with guide plate 1, guide plate 1 has for gage 2 and passes, the pilot hole being slidably matched with scale section 21 guiding, in the right part of gage 2, have and the positioning tube inner peripheral surface guiding guide and limit axle collar 23 that is slidably matched, rely on like this guide plate 1 and the guide and limit axle collar 23 can realize the left and right guiding movement of gage 2 in positioning tube 3, simultaneously the limit block face of boss 10 and end cap 5 coordinates with the guide and limit axle collar 23 again that to realize the left and right of gage 2 spacing.
Between gage 2 and the boss 10 of positioning tube 3, be provided with one-way locking mechanism, one-way locking mechanism comprises and being arranged in scale section 21, the ratchet 22 of laying along its length on downside wall, the top that is positioned at ratchet 22 on the outer peripheral face of positioning tube 3 offers the pilot hole 4 that runs through boss, in pilot hole 4, be provided with one-way lock, in the present embodiment, one-way lock is the ratchet 8 being hinged in pilot hole, on the jointed shaft of ratchet 8, be arranged with torsion spring 7, under the effect of torsion spring 7, the claw of ratchet 8 is down in two ratchets 22, and coordinate and prevent gage 2 retaining to the right with the right flank block of left side ratchet, if gage 2 is applied to acting force left, the elastic force that gage 2 can overcome torsion spring 7 moves to left, ratchet 8 away from claw one end, be release force section, release force section is near the opening's edge position of pilot hole, presses release force section downwards and can make ratchet overcome the motion of torsion spring elastic force, and then realize the release of gage 2.
As further optimization, at gage 2, be arranged with top and be pressed in the reseting pressuring spring 9 between boss 10 and the guide and limit axle collar 23, reseting pressuring spring 9 is return springs, the left side apical grafting of the right side apical grafting of the left end of reseting pressuring spring 9 and boss 10, right-hand member and the guide and limit axle collar 23, wherein the right side of boss is thrust step surface, and the left side of the guide and limit axle collar is reset step surface, like this when gage moves to left after certain distance release, under the effect of reseting pressuring spring 9, gage can Rapid reset.
When above-described embodiment is specifically measured the moving contact of isolating switch and the interlock degree of depth of static contact, before interlock, Mume flower contact 12 1 sides by whole measurer by contact arm 11 are inserted in contact arm 11, until the positioning reference plane of end cap 5 contacts with the right side of contact arm 11, now pushing tow rod 6 is deep in Mume flower contact 12; After assembling, circuit breaker cart is shaken to occlusal position, in this process, pushing tow rod 6 promotes gage 2 and moves and make reseting pressuring spring 9 compressions under the thrusting action of static contact 13, the scale section 21 of gage 2 is stretched out the corresponding end of positioning tube 3 gradually, simultaneously under the one-way locking effect of ratchet 8, prevent gage 2 occur retaining to the right phenomenon until interlock put in place; Afterwards, go out circuit breaker cart, take out measurer, read the reading in scale section 21, this reading is the size of the interlock degree of depth; After reading, press ratchet, under the effect of reseting pressuring spring, gage resets.
In other embodiments, one-way lock also can adopt along positioning tube radially-directed and move the lock pin being assemblied in pilot hole, sheathed locking stage clip on lock pin, like this under the effect of locking stage clip, an end towards gage of lock pin is deep in ratchet, like this when gage moves to left, ratchet can promote the elastic force motion that lock pin overcomes stage clip, make ratchet along crossing lock pin, pull lock pin can realize release in the other direction simultaneously, therefore, also can realize the one-way locking of gage, wherein, the end away from gage of lock pin is release force section.
In other embodiments, pushing tow rod also can be wholely set with gage.
