Abstract
The utility model aims to provide a spring operation mechanism interlocking device which is simple in structural design and reliable in motion. The device comprises a mechanism side plate and an output shaft. One side of the mechanism side plate is provided with a closing pawl reset spring and a closing pawl. The device further comprises an interlocking reset spring and an interlocking plate. One end of the interlocking reset spring is connected with the mechanism side plate while the other end of the interlocking reset spring is connected with the interlocking plate. One end of the closing pawl reset spring is connected with the mechanism side plate while the other end of the closing pawl reset spring is connected with the closing pawl. The closing pawl is provided with a first inclined face. The interlocking plate is provided with a second inclined face fitted with the first inclined face. The output shaft is provided with a crank arm. According to the device of the utility model, the structure is simple and a small number of components are used. A spring operation mechanism is enabled to close smoothly in an opening position and also to close again in a closing position, thereby being high in reliability.
Description
Technical field
The utility model relates to equipment for power transmission and distribution technical field, is specifically related to a kind of spring operating mechanism interlock.
Background technology
Current middle pressure field spring operating mechanism adopts distributed unit in circuit breaker mechanism case, and each functional unit integrated level of mechanism is not high, causes the problems such as spring operating mechanism prevents the interlock complexity of reclosing, and parts are more, poor reliability.
Utility model content
The purpose of this utility model is to provide that a kind of structural design is simple, reliable in action floor spring operating mechanism interlock.
For this reason, the utility model adopts following technical scheme: a kind of spring operating mechanism interlock, comprise mechanism's side plate, output shaft, mechanism's side plate one side is provided with closing pawl back-moving spring, closing pawl, also comprise interlocking resetting spring, interlock plate, described interlocking resetting spring one end is connected with mechanism side plate, the described interlocking resetting spring other end is connected with interlock plate, described closing pawl back-moving spring one end is connected with mechanism side plate, the described closing pawl back-moving spring other end is connected with closing pawl, described closing pawl is provided with the first inclined-plane, described interlock plate is provided with second inclined-plane suitable with the first inclined-plane, described output shaft is provided with connecting lever.
Further, described interlock plate is provided with guide groove, and described guide groove is connected with interlock plate by pin.
Further, described guide groove is two.
The beneficial effects of the utility model are: simple in structure, parts are few, and reliability is high, realize spring operating mechanism and can close a floodgate smoothly in the time of open position, and spring operating mechanism can again close a floodgate in the time of closing position.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 to 5 figure, a kind of spring operating mechanism interlock, comprise mechanism's side plate 1, output shaft 8, mechanism's side plate 1 one sides are provided with closing pawl back-moving spring 2, closing pawl 3, also comprise interlocking resetting spring 4, interlock plate 5, interlocking resetting spring 4 one end are connected with mechanism side plate 1, interlocking resetting spring 4 other ends are connected with interlock plate 5, closing pawl back-moving spring 2 one end are connected with mechanism side plate 1, closing pawl back-moving spring 2 other ends are connected with closing pawl 3, closing pawl 3 is provided with the first inclined-plane 31, interlock plate 5 is provided with second inclined-plane 51 suitable with the first inclined-plane 31, output shaft 8 is provided with connecting lever 7.
Interlock plate 5 is provided with two guide grooves 52, and guide groove 52 is connected with interlock plate 5 by pin 6, makes the interlock plate 5 can stably translational.
Spring operating mechanism is in the time of closing position, when connecting lever 7 and the interlock plate 5 being connected with output shaft 8 departs from, interlock plate 5 under the effect of interlocking resetting spring 4 to left, the second inclined-plane 52 on interlock plate 5 is mediated with the first inclined-plane 31 on closing pawl 3, stop closing pawl 3 to be threaded off, prevent spring operating mechanism reclosing.
Spring operating mechanism is in the time of open position, the connecting lever 7 being connected with output shaft 8 promotes interlock plate 5 to right translation, the second inclined-plane 52 on interlock plate 5 is departed from the first inclined-plane 31 on closing pawl 3, and closing pawl 3 is threaded off, and guarantees that spring operating mechanism can close a floodgate smoothly.
