The guide rail installing mechanism has the characteristics of small parts, simple structure, skillful design and very convenient installation and use, and an electric appliance can be fixed firmly after the guide rail installing mechanism is installed.
Description
Technical field
The present invention relates to a kind of circuit protection mechanism.Particularly relate to a kind of mechanism that is installed on the guide rail, specifically be meant a kind of miniature circuit breaker (small-sized residual current circuit breaker) to be installed in the installing mechanism on the guide rail.
Background technology
For circuit breaker is fixed on the guide rail, generally all be provided with guide rail installing mechanism on the housing of miniature circuit breaker, on the bottom surface of housing, be provided with draw-in groove and movable support, there is the assembling difficulty in the movable support of existing guide rail installing mechanism more, cause damage easily, electrical equipment is fixing unstable on guide rail, slides easily, and is not too convenient in the use.
Summary of the invention
Purpose of the present invention is exactly the shortcoming that has overcome in the above-mentioned existing technology, a kind of guide rail installing mechanism that can stop in the centre position is provided, this guide rail installing mechanism is simple in structure, design ingenious, install and use very convenient and the characteristics of back electrical equipment fixation be installed.
In order to realize above-mentioned purpose, guide rail installing mechanism of the present invention adopts following technical scheme: a kind of guide rail installing mechanism, and preferred a kind of circuit breaker, it comprises that a bottom is provided with the housing that gathering sill, positive stop lug boss constitute a mounting portion.One supporting member is provided on this mounting portion, this supporting member is installed on the housing in the mode of sliding, the first part, side of glide direction positive stop lug boss is a swallow-tail form for the taper latter part, have elastic edge in the middle of the supporting member, the side of elastic edge also has partly protruding and constitutes an elastomeric element with elastic edge.So that circuit breaker ground tightly is clamped on the guide rail.
Described gathering sill and housing bottom coplanar have increased the capacity of housing so to greatest extent under the product equal volume.
Described supporting member is made by plastic material.
Described supporting member downside has big slot.Can satisfy the needs of other mode of connection circuit breaker like this, for example: plug in circuit breaker.
Described supporting member upside has the hole of forming than the stack of small rectangle and a circular arc by, circular arc position projection.Like this applicable to more eurypalynous instrument (manifold or crosshead instrument), so that loading and unloading.
Described support bases is provided with the yielding groove, matches with housing positive stop lug boss arc surface in installation process.
Guide rail installing mechanism of the present invention is very convenient when installing and use, as long as firmly from inside to outside push away a lower supporting part, the arc surface of positive stop lug boss face is by the yielding groove of supporting member, supporting member just is installed on the base, if continue to push hard supporting member or pull outward from the screwdriver hole with screwdriver (also available other instrument), make the middle elastomeric element of supporting member the elastomeric element distortion be resetted again, thereby make supporting member rest on the centre position through positive stop lug boss.Can be put into circuit breaker on the guide rail or from guide rail very easily this moment takes off circuit breaker, after moving to suitable position on the guide rail, as long as firmly push away a lower supporting part more from outside to inside, the supporting member elastomeric element deforms, under the effect of taper surface to being pressed on the guide rail, thereby circuit breaker is fixed on the guide rail.

The present invention is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the schematic diagram of a kind of state of this guide rail installing mechanism.
Fig. 2 is the schematic diagram of the another kind of state of this guide rail installing mechanism.
Fig. 3 is the schematic diagram of the third state of this guide rail installing mechanism.
Fig. 4 is the housing parts structural representation.
Fig. 5 is the structural representation of supporting member.
Embodiment
As shown in Figure 5, the lower limb of supporting member 2 sidewalls of being made by plastic material 25 has two laths 27, and they are arranged on the inboard of sidewall, towards each other.Downside has a bigger slot 29, upside has the screwdriver hole of being made up of a small rectangle and circular arc stack 22, and the circular arc limit arches upward 26, and the centre is provided with an elastomeric element 24, it is made of elastic edge 24b and lateral projections part 24a, and this projection is arc transition towards each other.Upside is provided with overhead gage 23, and downside is provided with lower baffle plate 28, and overhead gage 23 bottoms and the part 26 that arches upward are provided with makes a concession groove 21.
As shown in Figure 4, housing 1 is provided with gathering sill 11 and housing bottom 13 same planes, also being provided with first part, positive stop lug boss 12 glide direction side is that taper 12a latter part is swallow-tail form 12b, and the front in positive stop lug boss front is that arc transition face 12c back is plane 12d.
2 liang of laths 27 of supporting member are placed on alignment guide groove 11 on the bottom faces 13 of housing 1, as long as firmly from inside to outside push away a lower supporting part 2, the arc surface 12c of positive stop lug boss face makes its overhead gage 23 and arches upward partly 26 through the yielding groove 21 by supporting member 2 after the micro-strains, supporting member 2 just is installed on the base 1 as shown in Figure 1, in this state, supporting member 2 is positioned at innermost position, reset after overhead gage 23 distortion on the supporting member 2 this moment back plane 12d position of the positive stop lug boss that blocks housing 1 makes it can not continue to slide by instrument left.Elastomeric element 24 is in the non-stress state.If continue firmly from inside to outside to push away a lower supporting part 2, perhaps 22 usefulness screwdrivers (also available other instrument) pull outward and arch upward partly 26 from the screwdriver hole, make that elastomeric element 24 lateral projections part 24a's pass through the position of positive stop lug boss taper surface 12a to positive stop lug boss 12b.The elasticity part distortion resets again in this process, thereby makes supporting member 2 rest on the centre position.As shown in Figure 2.
Under state shown in Figure 2, lower baffle plate 28 blocks positive stop lug boss 12 can not make it continue to move right, and this moment, elastomeric element 24 also was in the non-stress state.Can very easily circuit breaker be placed on the guide rail or from guide rail and take out circuit breaker, after moving to suitable position on the guide rail, as long as firmly push away a lower supporting part 2 more from outside to inside, elastomeric element 24 is stressed, elastic edge 24b is subjected to an outer tension force, and strain, state as shown in Figure 3 take place, this moment supporting member 2 under the effect of taper surface 12a to being pressed on the guide rail, thereby circuit breaker is fixed on the guide rail.
