The guide rail mounting mechanism has the characteristics of small parts, simplicity in structure, ingenious in design and convenience in installation and use, and electrical appliances are fixed firmly after the mounting.
Description
Technical field
The utility model relates to a kind of circuit protection mechanism.Particularly relate to a kind of mechanism that is installed on the guide rail, specifically refer to a kind of miniature circuit breaker (Minitype electrical leakage breaker) is installed in 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, be provided with draw-in groove and movable support in the bottom surface of housing, there is the assembling difficulty in the movable support of existing guide rail installing mechanism more, cause easily damage, electrical equipment is fixed unstable at guide rail, slide easily, and is not too convenient in the use.
The utility model content
The purpose of this utility model 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 install after the characteristics of electrical equipment fixation.
In order to realize above-mentioned purpose, guide rail installing mechanism of the present utility model 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 consist of a mounting portion.Provide a supporting member in 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 that the taper latter part is swallow-tail form, have elastic edge in the middle of the supporting member, also there is the part projection side of elastic edge and consists of an elastomeric element with elastic edge.In order to 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 a larger slot.Can satisfy like this needs of other mode of connection circuit breaker, for example: plug in circuit breaker.
Described supporting member upside has the hole that forms than the stack of small rectangle and a circular arc by, and the circular arc position is protruding.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 utility model 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 limit convex table top 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 through positive stop lug boss the elastomeric element distortion be resetted again, thereby make supporting member rest on the centre position.Can be put into circuit breaker on the guide rail or from guide rail very easily this moment takes off circuit breaker, after guide rail moves to suitable position, as long as firmly push away from outside to inside again a lower supporting part, 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.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
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 25 of being made by plastic material has two laths 27, and they are arranged on the inboard of sidewall, towards each other.Downside has a larger slot 29, upside has the screwdriver hole 22 that is comprised of a small rectangle and circular arc stack, and arc-shaped edges 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-shaped transitional surface 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 limit convex table top make its overhead gage 23 and the part 26 that arches upward 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) part 26 that arches upward that pulls outward from the screwdriver hole, make elastomeric element 24 lateral projections parts 24a through the position of positive stop lug boss taper surface 12a to positive stop lug boss 12b.Reset again in this process Elastic part distortion, thereby make 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 guide rail moves to suitable position, as long as firmly push away from outside to inside again a lower supporting part 2, elastomeric element 24 is stressed, elastic edge 24b is subject to an outer tension force, and strain, as shown in Figure 3 state occur, 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.
