Description
Technical field
Electric switch technical field is the utility model is related to, specifically, is related to a kind of rigid interlocking mechanism.
Background technology
The distribution box interlocking mechanism of the prior art mostly uses soft stay-supported structure, its is simple in structure, of low cost,
In use, the elasticity of bracing wire directly influences separating brake interlocking mechanism usability, and the tightness of bracing wire is affected by temperature change
Change larger, phenomena such as causing the inseparable lock of the easy generating mechanism of use site or overburden fuse failure, and bracing wire is easy to aging, uses
Service life is shorter, reduce further the reliability used.
Utility model content
It is safe and reliable the purpose of this utility model is to provide a kind of rigid interlocking mechanism, it is affected by temperature small.
Technical solution is used by rigid interlocking mechanism disclosed in the utility model:
A kind of rigidity interlocking mechanism, including fixing piece, the fixing piece are equipped with connecting shaft, the one end of the connecting shaft connection
Handle, the connecting shaft are equipped with cam, and the cam rolls first latch one end of connection, and the first latch other end passes through
Fixing piece is set, and first latch surface is socketed spring, and the spring one end is fixed on the first latch, and the other end abuts spring
Set, the spring pocket are fixedly connected with fixing piece.
Preferably, the cam face is equipped with groove, and the groove is arranged on the sliding surface of cam and the first latch,
The groove is set along the first latch glide direction, cross sectional shape and first latch top surface shape of the groove along glide direction
It is harmonious.
Preferably, through hole is set on first latch, the through hole sets the second latch, and the spring one end is consolidated
Due to the second latch.
Preferably, cambered surface prominent centered on the first latch top surface.
Preferably, the cam face is conformed with, and the projection is arranged on cam and the first latch sliding surface
Peak.
Preferably, the cam face Carburization Treatment.
The beneficial effect of rigid interlocking mechanism is disclosed in the utility model：The utility model is driven convex using handle rotation
Wheel rotates, and then drives the first latch to move up and down the locking for coming distribution control box Xiamen and opening, and whole transmission process is firm
Property transmission, temperature distortion is small, and stability is good.
Brief description of the drawings
Fig. 1 is the right view of the utility model rigidity interlocking mechanism.
Fig. 2 is the front view of the utility model rigidity interlocking mechanism.
Fig. 3 is the stereogram of the utility model rigidity interlocking mechanism.
Embodiment
The utility model is further elaborated and illustrated with reference to specific embodiment and Figure of description:
Please refer to Fig.1,2 and 3, a kind of rigidity interlocking mechanism, including fixing piece 1, the fixing piece 1 be fixed under distribution box
Door, the fixing piece 1 are equipped with connecting shaft 2, and 2 section of connecting shaft of the connecting shaft 2 and 1 junction of fixing piece is circular, institute
State the rolling of connecting shaft 2 and be connected to fixing piece 1, described 2 one end of connecting shaft is connected with handle 3, and the handle 3 is used to drive described
Connecting shaft 2 rotates, and 3 lower end of handle is the cylindrical structure of two side portions excision, and the handle 3 is removably connected with key,
The key is circular configuration, and card slot is equipped with center, and the cylinder that the card slot is cut off with the two side portions is harmonious, and rotates key
Spoon, drives the connecting shaft 2 to rotate.
The connecting shaft 2 is equipped with cam 4, the cam 4 and 2 integrally casting shaping of connecting shaft, and the cam 4, which rolls, to be connected
5 one end of the first latch is connect, first latch 5 is cylindrical, prominent cambered surface, first latch centered on its upper and lower top surface
5 other ends are set through fixing piece 1, and first latch 5 is equipped with through hole 6, set the second latch at the through hole 6, and described
Two latches are set through the through hole, and spring one end is fixed with second latch, and the spring is used to drive described first
Latch 5 moves up, and the spring is socketed on the first latch 5, its other end is connected to spring pocket 7, and the spring pocket 7 is fixed on
Fixing piece 1.
During locking rigidity interlocking mechanism, handle 3 rotates clockwise, and band moving cam 4 rotates clockwise, and driving is slided with cam 4
First latch 5 of dynamic connection moves down, and spring is compressed at this time, and there is a corresponding jack in the lower section of the first latch 5, and first
Latch 5 moves down insertion jack to realize locking, and when opening retaining mechanism, handle 3 rotates counterclockwise, band 4 inverse time of moving cam
Pin rotates, and spring extends at this time, and the first latch 5 of driving moves up, and the first latch 5 leaves jack and opened to realize, whole to pass
Dynamic process is positive drive, and temperature distortion is small, and stability is good.
In such scheme, 4 case-carbonizing of the cam processing, to strengthen its surface rub resistance ability, improves service life.
In such scheme, 4 surface of cam is conformed with, and the projection is arranged on 4 and first latch of cam, 5 sliding surface
Peak, in 4 rotation process of cam, coordinate with the first latch 5 realize the peak that is moved up and down to the first latch 5 and
Minimum point progress is spacing, prevents rotational angle excessive or too small, it is unreliable to cause to lock.
In such scheme, the slidingsurface of the cam 4 is equipped with groove, and the groove is set along 5 glide direction of the first latch
Put, the groove 4 is harmonious along the cross sectional shape of glide direction with 5 top surface shape of the first latch, due to 4 He of cam of the prior art
First latch 5 is contact of the point with face, easy to wear, is shortened using process length, influences final locking effect, the utility model
Groove is set, the connection mode of 4 and first latch 5 of cam is changed into contact of the line with face, contact area increase, is not easy to grind
Damage, reliable lock improve.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
Lead to it will be appreciated by the skilled person that can be to the technical solution of the utility model technical scheme is modified or replaced equivalently, without departing from this
The spirit and scope of utility model technical solution.
