Description
Technical field
The utility model relates to a kind of extraction position locking mechanism, belongs to the electric switch field.
Background technology
Along with power engineering to improving constantly that equipment for power transmission and distribution requires, also more and more higher to the requirement of withdrawable circuit breaker, safety operation, operation are reliable, the synchronous entering of body, the developing direction that human oriented design is present withdrawable circuit breaker.
The frame of taking out of withdrawable circuit breaker is used for circuit breaker and is placed on and takes out the frame slide plate, extracts out and pushes to make things convenient for circuit breaker.Take out the frame slide plate and directly have influence on the balance that circuit breaker packs into and the reliability of secondary connection terminal contraposition.Domestic like product does not all have the extraction position locking mechanism, can cause the extraction location fuzzy unclear like this, reduces its reliability and security greatly.
Schneider MT40 withdrawable circuit breaker provides a kind of sliding locking mechanism of pull-out type, and it comprises the upper rail 2, the lower guideway 4 that are located on the side plate 1, be located at guide plate 9 between the lower guideway, be located at the slide plate 10 on the guide plate 9.Slide plate 10 is done and is slidingly matched with being installed in nail 11 on the guide plate 9 by groove 12, and the groove 15 of guide plate 9 is done and is slidingly matched with being installed in nail 14 on the slide plate 10, and slide plate 10 is slidingly mounted on the guide plate 9.The below, rear end of guide plate 9 has additional down lockplate 7, and following lockplate 7 has retaining pin 5 and can rotate around little axle 3.When slide plate and guide plate are extracted out fully, the retaining pin 5 of following lockplate 7 touches the front end of lower guideway 4, following lockplate 7 cooperates with the projection 6 of guide plate 9 rear ends makes down lockplate 7 remain on horizontal level, and the front end projection 13 of following lockplate 7 is spacing by the guide plate pin 8 of below, slide plate 10 rear ends, can realize the locking of upper rail 2 and lower guideway 4, promptly extract the locking of position out.
The locking institute condition of extracting the position out is the front end that retaining pin 5 touches lower guideway 4, and the front end projection 13 of following lockplate 7 is by guide plate pin 8 lockings of below, slide plate 10 rear ends.When pushing slide plate 10, the spacing cancellation of 8 pairs of following lockplate 7 front end projectioies 13 of guide plate pin of below, slide plate 10 rear ends, following lockplate 7 can rotate up around axle 3, at the state that slide plate 10 does not push fully, to extract locking position out and lost efficacy in advance, slide plate 10 is in movable state simultaneously with guide plate 9, but both free movements, asynchronous when causing the circuit breaker left and right sides to push caused clamping stagnation when causing circuit breaker to push, directly have influence on the accuracy of secondary terminal contraposition on the circuit breaker.
The utility model content
In view of above-mentioned, the utility model designs a kind of extraction position locking mechanism, and it can not cause when pushing slide plate, guide plate and slide plate interlock, the problem of guide plate and lower guideway lockout failure.
The utility model is achieved through the following technical solutions:
A kind of extraction position locking mechanism, comprise base plate, pair of side plates, guide plate, slide plate, the pair of side plates symmetry is installed on the base plate, the inboard of each side plate is upper rail and lower guideway fixedly, guide plate is installed between the upper and lower guide rail slidably, slide plate is installed on the guide plate slidably, it is characterized in that: described guide plate is provided with axle, plate shape lever is housed on this axle, and lever can pivot; The forearm of described lever is the wedge shape arm, but the bottom of lever postbrachium has the retaining pin of a stopper lower guideway front end.
Further:
The slide plate bottom has the inclined-plane, and this inclined-plane can touch the lever forearm in the process that slide plate slides backward, and the forearm of lever is rotated around axial lower guideway direction.
The retaining pin of lever postbrachium bottom can be around axial lower guideway direction motion under no external force effect.
Have on the guide plate and can limit the projection of lever postbrachium to the motion of lower guideway direction.
The beneficial effects of the utility model are: during the locking of guide plate and lower guideway, by lever postbrachium protruding spacing by below, guide plate rear end, make lever keep level, it is more reliable and more stable that guide plate and lower guideway are locked.In pushing the process of slide plate, have only after the forearm of lever is depressed on the inclined-plane of slide plate fully, guide plate just unlocks with lower guideway.And slide plate push put in place before, the retaining pin of lever postbrachium is the front end of stopper lower guideway always, thereby can not cause when pushing slide plate, the interlock of guide plate and slide plate, the problem of guide plate and lower guideway lockout failure.

Fig. 3 is the partial enlarged drawing at A place among Fig. 2.
Embodiment
The utility model is a kind of extraction position locking mechanism, comprise base plate, pair of side plates, guide plate, slide plate, the pair of side plates symmetry is installed on the base plate, the inboard of each side plate is upper rail and lower guideway fixedly, guide plate is installed between the upper and lower guide rail slidably, slide plate is installed on the guide plate slidably, guide plate is provided with axle, plate shape lever is housed on this axle, and lever can pivot; The forearm of lever is the wedge shape arm, but the bottom of lever postbrachium has the retaining pin of a stopper lower guideway front end.The slide plate bottom has the inclined-plane, and this inclined-plane can touch the lever forearm in the process that slide plate slides backward, and the forearm of lever is rotated around axial lower guideway direction.The retaining pin of lever postbrachium bottom can be around axial lower guideway direction motion under no external force effect.Have on the guide plate and can limit the projection of lever postbrachium to the motion of lower guideway direction.
Describe in detail below in conjunction with accompanying drawing.
As Fig. 2, shown in Figure 3, pair of side plates 1 symmetry respectively is placed with a cover slide mechanism.The upper rail 2 of slide mechanism, lower guideway 3 are installed on the side plate 1, be slidingly fitted with guide plate 9 between last lower guideway, slide plate 10 by itself groove 12 be installed in nail 11 on the guide plate 9 and do and be slidingly matched, guide plate 9 is done and is slidingly matched with being installed in nail 14 on the slide plate 10 by the groove 15 of itself, and slide plate 10 is slidingly mounted on the guide plate 9.
Outwards extracting out in the process of slide plate 10, when slide plate 10 extract out put in place and guide plate 9 extract out put in place after, the retaining pin 4 of following lockplate 6 lower ends touches the front end of lower guideway 3 and descends the rear end of lockplate 6 spacing by the projection 5 of below, guide plate 9 rear ends, make down lockplate 6 keep level, can realize the locking of guide plate 9 and lower guideway 3.
In the process that moves inward slide plate 10, depress down the wedge shape arm 8 of lockplate 6 front ends gradually when the inclined-plane 13 of slide plate 10 belows, make down lockplate 6 around axle 7 rotation counterclockwise, cooperate with lower guideway 3 front ends and make guide plate 9 releases thereby force down the retaining pin 4 of lockplate 6 rear ends to begin disengaging.To slide plate 10 push put in place after, retaining pin 4 breaks away from and lower guideway 3 fully, the locking of guide plate 9 and lower guideway 3 is removed fully, guide plate 9 can be pushed into drawout chassis.
