Abstract
The utility model discloses a guide way installation mechanism for the small sized circuit breaker, comprising a base, and a supporting member which can be glidingly arranged on the base. The utility model is characterized in that: a grooved capability of holding the spring is arranged at central section of the supporting member; a baffle is arranged on the base; the spring is arranged between the baffle and the supporting member; a barb projected to the middle is arranged at two ends of the groove on the supporting member, and an inclined plane corresponding to the barbs on the supporting member is arranged at two ends of the baffle. The utility model has the advantages that: the guide way installation mechanism is convenient in use; the supporting member is only pushed once with force from inside to outside, the barbs can slide over the after tiny deformation and hook outside the baffle, which ensures the supporting member to keep in the middle part; meanwhile, the circuit breaker can be conveniently put on the guide way, and the supporting member is pushed once with force from outside to inside, then the barbs can return to the inner side of the baffle after tiny deformation, so as to fix the circuit breaker on the guide way.
Description
Technical field
The utility model relates to a kind of miniature circuit breaker, is specifically related to miniature circuit breaker is fixed on installing mechanism on the guide rail.
Background technology
China's utility model patent (ZL200520040309.X) discloses a kind of guide rail installing mechanism of miniature circuit breaker, it comprises a base and a supporting member that is installed on the base, the bottom surface of supporting member is provided with to both sides outstanding front wing panel and rear fender, the afterbody of rear fender is provided with barb, base is provided with the chute that cooperates with front wing panel and rear fender, the afterbody of chute is provided with the boss that cooperates with barb, also be provided with the depression of holding spring on the supporting member, the right-hand member of spring withstands on the supporting member, and left end withstands on the baffle plate of base.This guide rail installing mechanism is very easy when assembling, as long as place spring earlier, the front wing panel of supporting member is put into the chute of base by the groove on the base, push hard a lower supporting part then from right to left, it is stuck in the base, under not by the situation of instrument, again can't takes out.
But this guide rail installing mechanism still has not too perfect place, for circuit breaker is fixed on the guide rail, sometimes need to shift the guide rail installing mechanism of a lot of products onto a centre position all from back to front, be suspended to product on the guide rail together one by one again, unification pushes away guide rail installing mechanism from front to back then, product is fixed on the guide rail, the installation of product is just convenient a lot of like this, the guide rail installing mechanism of above-mentioned miniature circuit breaker can't satisfy this requirement, also is not too convenient in the use therefore.
The utility model content
The technical problems to be solved in the utility model provides a kind of guide rail installing mechanism that can stop in the centre position.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of guide rail installing mechanism of miniature circuit breaker, comprise base and the supporting member that is slidably mounted on the base, the middle part of supporting member is provided with the groove that can hold spring, base is provided with baffle plate, spring is arranged between baffle plate and the supporting member, and the groove both sides on the described supporting member are provided with the barb that protrudes to the centre, and the both sides of described baffle plate are provided with and the relative inclined-plane of barb on the supporting member.
Guide rail installing mechanism of the present utility model is very convenient in use, only firmly from inside to outside push away a lower supporting part, the barb of groove both sides slides along the inclined-plane on the baffle plate, through just slipping over this inclined-plane after the small distortion, barb just is hooked in the outside of baffle plate, thereby makes supporting member rest on the centre position.Can be put into circuit breaker on the guide rail very easily this moment, after moving to suitable position on the guide rail, as long as firmly push away a lower supporting part more from outside to inside, barb just can be got back to the inboard of baffle plate again through a small distortion, supporting member inwardly is pressed on the guide rail under the effect of spring, thereby circuit breaker is fixed on the guide rail.
Preferably, described supporting member is made by plastic material, and the both sides of its groove also are provided with two slits parallel with groove, forms two elastic edges between slit and groove, and described barb is positioned at the inboard of these two elastic edges.This structure has better elasticity, makes the easier generation strain of barb, thereby makes barb both can be hooked in the outside of baffle plate, also may slide into the inboard of baffle plate.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the schematic diagram of a kind of state (barb is positioned at the baffle plate inboard) of the utility model guide rail installing mechanism.
Fig. 2 is the schematic diagram of the another kind of state (barb is positioned at the baffle plate outside) of the utility model guide rail installing mechanism.
Fig. 3 is the structural representation of base portion.
Fig. 4 is the structural representation of supporting member.
Embodiment
As shown in Figure 4, the outside of the supporting member of being made by plastic material 2 is provided with to both sides outstanding front wing panel 25 and rear fender 26, the middle part of supporting member 2 is provided with a groove 21, the both sides of groove 21 also are provided with two slits parallel with groove 23, form two elastic edges 24 between slit 23 and groove 21, the inboard of these two elastic edges 24 is provided with the barb 22 that protrudes to the centre.
As shown in Figure 3, base 1 is provided with baffle plate 11, and the both sides of baffle plate 11 are provided with inclined-plane 12.When supporting member 2 is installed on the base 1, in the groove 21 of supporting member 2, put into a spring, this spring is compressed between the end face of baffle plate 11 and groove 21, also be provided with the chute (not shown) that matches with front wing panel 25, rear fender 26 on the base 1, thereby supporting member 2 can slide in the certain limit on base 1.
As shown in Figure 1, in this state, supporting member 2 is positioned at innermost position, and this moment, the barb 22 on the supporting member 2 was relative with inclined-plane 12 on the baffle plate 11.Under free state, the distance between two barb 22 tips is than the smaller 0.5mm of width of baffle plate 11 the widest part.If firmly from inside to outside push away a lower supporting part 2, barb 22 outwards slides along the inclined-plane 12 on the baffle plate, article two, elastic edge 24 is subjected to an outer tension force, small strain takes place, thereby barb 22 can slip over inclined-plane 12, be hooked in the outside of baffle plate 11, thereby make supporting member 2 rest on the centre position, as shown in Figure 2.
Can be put into circuit breaker on the guide rail very easily this moment, 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, barb 22 just can be got back to the inboard of baffle plate 11 again through a small distortion with two elastic edges 24, it is state shown in Figure 1, this moment, supporting member 2 inwardly was pressed on the guide rail under the effect of spring, thereby circuit breaker is fixed on the guide rail.
