Abstract
It the utility model is related to a kind of automatic dropout and self-locking device, a kind of automatic dropout and self-locking device, including direct current generator, reduction box, rocking arm, drive rod and mounting base, the direct current generator is fixed on mounting base, the reduction box is arranged in the output end of direct current generator, the output end of the direct current generator is connected with rocking arm, the drive rod is flexibly connected with rocking arm, the design makes breaker that there is remote control breaker to thread off automatically, the effect of anti-closing by hand, solving breaker in the prior art can not thread off automatically, often there is the problem of closing by hand situation.
Description
Technical field
Breaker technical field is the utility model is related to, is specially a kind of automatic dropout and self-locking device.
Background technology
Breaker is the electric current for referring to close, carry and cut-off under normal loop condition and can closed, when defined
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition.Breaker is divided into primary cut-out by its use range
With low-voltage circuit breaker, high-low pressure identification of boundaries is relatively fuzzyyer, more than 3kV typically is referred to as into High-Voltage Electrical Appliances, breaker can be used to
Electric energy is distributed, infrequently starts asynchronous motor, the implementations such as power circuit and motor are protected, when they occur seriously
When overload or the failure such as short-circuit and under-voltage can automatic shutdown circuit, its function is equivalent to Fuse switch with crossing underheat relay
The combination of device etc..And it is latter in disjunction fault current as need not change parts.At present, obtained a wide range of applications.
Breaker can not thread off automatically in the prior art, the situation of closing by hand often occur, in summary, now be badly in need of one
Automatic dropout and self-locking device are planted to solve above-mentioned produced problem.
Utility model content
In view of the deficienciess of the prior art, the utility model purpose is to provide a kind of automatic dropout and self-locking device, with
Solve the problems, such as to propose in above-mentioned background technology, the utility model is easy to use, simple to operate, and systematicness is high, practical.
To achieve the above object, the utility model provides following technical scheme：A kind of automatic dropout and self-locking device, including
Direct current generator, reduction box, rocking arm, drive rod and mounting base, the direct current generator are fixed on mounting base, the deceleration
Case is arranged in the output end of direct current generator, and the output end of the direct current generator is connected with rocking arm, the drive rod and rocking arm
It is flexibly connected.
Further, the direct current generator is fixedly mounted on mounting base by motor fixing screw.
Further, the drive rod is flexibly connected by movable Liu Ding with rocking arm.
Compared with prior art, the beneficial effects of the utility model are：Because the utility model with the addition of direct current generator, deceleration
Case, rocking arm, drive rod and mounting base, the design make breaker that there is remote control breaker to thread off automatically, prevent closing manually
The effect of lock, solves in the prior art that breaker can not thread off automatically, the problem of closing by hand situation often occurs.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In reference：1. direct current generator；2. reduction box；3. rocking arm；4. drive rod；5. movable Liu Ding；6. motor is fixed
Screw；7. mounting base.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of automatic dropout and self-locking device, including direct current
Motor 1, reduction box 2, rocking arm 3, drive rod 4 and mounting base 7, direct current generator 1 are fixed on mounting base 7, and reduction box 2 is pacified
In the output end of direct current generator 1, the output end of direct current generator 1 is connected with rocking arm 3, and drive rod 4 connects with the activity of rocking arm 3
Connect, the design makes breaker that there is remote control breaker to thread off automatically, the effect of anti-closing by hand.
Direct current generator 1 is fixedly mounted on mounting base 7 by motor fixing screw 6, and drive rod 4 passes through movable Liu Ding 5
It is flexibly connected with rocking arm 3.
The utility model is at work：Remote operation runs direct current generator 1, output end 3 turns of the motion rocker arm of band of direct current generator 1
Dynamic, rocking arm 3 drives drive rod 4 to rotate, and the rotation of drive rod 4 realizes breaker and threaded off automatically, the effect of anti-closing by hand, so as to
Solve in the prior art that breaker can not thread off automatically, the problem of closing by hand situation often occur.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above, for
For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this
In the case of the spirit or essential attributes of utility model, the utility model can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the utility model is by institute
Attached claim rather than described above limit, it is intended that will fall in the implication and scope of the equivalency of claim
All changes are included in the utility model.Any reference in claim should not be considered as to the involved right of limitation
It is required that.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
