Abstract
The utility model provides a manual operation automatic blocking device. The manual operation automatic blocking device comprises a stroke switch, an interlocking plate, a compressed spring and an installing rack. The upper end of the interlocking plate is contacted with a contact of the stroke switch, and the lower end is arranged on the end face of the installing rack via the compressed spring. The installing rack is arranged at one side of a motor, and a hexangular operation shaft is arranged in a hole of the installing rack. One end of the hexangular operation shaft is connected with a decelerating mechanism of the motor, and the other end matches an operation handle. The manual operation automatic blocking device of the utility model can realize the circuit blocking of an electric power system automatically without needing to operate the interlocking plate artificially and by just using the operation handle during the process of a manual operation mechanism, and also has the advantages of being simple in structure and low in cost, being convenient to use, etc.
Description
Technical field
The utility model relates to the technical field that power switch closes load current, cut-offs zero load electric current, especially relates to a kind of manual operation self-locking gear.
Background technology
The effect that urban and rural power grids and track traffic electric power get up to people's life is increasing, has reached indivisible.In prior art, when before manual operation electric power system, need remove artificially to stir handle hole cover plate, remove to touch stroke switchgear with this cover plate, finally make this operation cover plate be fixed on the normally open position state of travel switch, realize the cut-out of electric motor loop electric power, now manual lever just can be deep in power transmission shaft and operate; After manual operation completes, transfer to manual lever, need to go artificially again to reverse this cover plate, make travel switch in normally off, connect electric motor loop.But, when forgetting that while reversing this cover plate, electric operating just cannot carry out.
So, be necessary to provide a kind of manual operation self-locking gear, without operating artificially cover plate, use action bars in the process of manual-operating mechanism, just can automatically realize the circuit interlocking of electric power system, to overcome the above-mentioned defect existing in prior art.
Utility model content
Technical problem to be solved in the utility model is: a kind of manual operation self-locking gear is provided, to overcome in existing manual operation electric power system, needs artificially to go in addition to close, the defect of turns on power circuit system.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of manual operation self-locking gear is provided, comprises: travel switch, interlock plate, stage clip and installing rack; The upper end of described interlock plate contacts with the contact of travel switch, and lower end is arranged on by stage clip on the end face of installing rack; Described installing rack is arranged on a side of motor, is provided with hexagonal operating axis in the hole of this installing rack, and one end of described hexagonal operating axis is connected with the reducing gear of motor, and the other end coordinates with operating grip.
Above-mentioned a kind of manual operation self-locking gear, described interlock plate is movable connection of end face with installing rack by pivot pin, and compression spring sleeve, on pivot pin, makes interlock plate slide on pivot pin according to the active force of stage clip.
Above-mentioned a kind of manual operation self-locking gear, described pivot pin and stage clip all circularize and are distributed on installing rack.
Adopted technique scheme, the beneficial effects of the utility model are: compared with prior art, a kind of manual operation self-locking gear of the present utility model, in operating grip inserts in installing rack hole, can drive interlock plate to move inward; When operating grip is inserted into after hexagonal operating axis, interlock plate has been pulled travel switch, and motor circuit is disconnected; Extract after hexagonal operating axis when operating grip, interlock plate resets under the effect of stage clip, and travel switch resets motor circuit is connected.A kind of manual operation self-locking gear of the present utility model, without operation interlocking plate artificially, use operating grip in the process of manual-operating mechanism, just can automatically realize the circuit interlocking of electric power system, and have simple in structure, cost is low, the advantage such as easy to use.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment;
Wherein: 1 is travel switch; 2 is interlock plate; 3 is stage clip; 4 is installing rack; 5 is hexagonal operating axis; 6 is reducing gear; 7 is operating grip; 8 is pivot pin.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model embodiment.
As shown in Figure 1, the preferred a kind of manual operation self-locking gear of the utility model, comprising: travel switch 1, interlock plate 2, stage clip 3 and installing rack 4.
The upper end of described interlock plate 2 contacts with the contact of travel switch 1, and lower end is arranged on by stage clip 3 on the end face of installing rack 4; Described installing rack 4 is arranged on a side of motor, is provided with hexagonal operating axis 5 in the hole of this installing rack 4, and one end of described hexagonal operating axis 5 is connected with the reducing gear of motor 6, and the other end coordinates with operating grip 7.
In the utility model preferred embodiment, described interlock plate 2 is movable connection of end face with installing rack 4 by pivot pin 8, and stage clip 3 is enclosed within on pivot pin 8, and interlock plate 2 is slided on pivot pin 8 according to the active force of stage clip 3.Preferably, described pivot pin 8 and stage clip 3 all circularize and are distributed on installing rack 4.
Operation principle: carry out manual operation to electric power system time, use the operating grip 7 matching with hexagonal operating axis 5.In operating grip 7 inserts the hole of installing rack 4, can drive interlock plate 2 to move inward, now stage clip 3 is compressed; When operating grip 7 is inserted into after hexagonal operating axis 5, interlock plate 2 moves inward again one section, has at this moment pulled travel switch 1, makes travel switch 1 disconnect the circuit loop of motor, and operating grip 7 just can be rotated operation.After manual operation completes, when operating grip 7 is transferred to hexagonal operating axis 5, due to the thrust of stage clip 3, interlock plate 2 is automatically shifted onto home position, and now travel switch 1 is also just got back to home position equally, makes the circuit loop of motor again closed.
As mentioned above, a kind of manual operation self-locking gear of the present utility model, in operating grip inserts in installing rack hole, can drive interlock plate to move inward; When operating grip is inserted into after hexagonal operating axis, interlock plate has been pulled travel switch, and motor circuit is disconnected; Extract after hexagonal operating axis when operating grip, interlock plate resets under the effect of stage clip, and travel switch resets motor circuit is connected.A kind of manual operation self-locking gear of the present utility model, without operation interlocking plate artificially, use operating grip in the process of manual-operating mechanism, just can automatically realize the circuit interlocking of electric power system, and have simple in structure, cost is low, the advantage such as easy to use.
The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection range of the present utility model.
