Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.Identical in the accompanying drawings parts are represented with identical label.
With reference to figure 1 and Fig. 2 the jungle gym that is used to roll over the shelf structure isolating switch of the present utility model is described, wherein, the three-phase of isolating switch is made up of three one poles, whenever have pillar 2 and be located at following porcelain vase 8 and last porcelain vase 6 on the pillar 2 successively, this jungle gym comprises: first anchor ear 4, hold tightly in the base flange that plays porcelain vase 8 and detachable; Second anchor ear (Fig. 4 illustrates) is held tightly in the top of last porcelain vase 6 flange and detachable; And first cat ladder 1 and second cat ladder 5, wherein, second cat ladder 5 removably is connected between first anchor ear 4 and second anchor ear, and an end of first cat ladder 1 is connected in pillar 3, and the other end is connected with first anchor ear 4.Fig. 1 and Fig. 2 show one first cat ladder 1 and two second cat ladders 5, and wherein, two second cat ladders 5 are arranged opposite to each other and couple together by stull.Certainly, only have one second cat ladder 5 and also be fine, just operating position is limited.
Further, with reference to figure 3 and Fig. 6 describe first anchor ear 4 structure and with the connected mode of first cat ladder 1 and second cat ladder 5, particularly, first anchor ear 4 is the chorista of two symmetries, one of them chorista is extended with two struts, and the end of each strut is for connecting groove structure.As can be seen from Figure 6, tube connector 12 (Fig. 6 illustrates) is connected in this groove by bolt, two vertical terraced bars at first cat ladder, 1 top penetrate from the lower end of tube connector 12 and are connected with this chorista of first anchor ear 4 by bolt, one bottom in two second cat ladders 5 penetrates from the upper end of tube connector 12 and is connected with this chorista of first anchor ear 4 by bearing pin 13, another chorista of first anchor ear 4 is extended with two struts that have blind hole 9 in the end, and the bottom of another in two second cat ladders 5 is plugged in the blind hole 9 and is fixed in this another chorista of first anchor ear 4 by pin.From Fig. 3, also can find out also to be provided with the bolt 10 that to screw towards the central axis of first anchor ear 4 on the chorista of first anchor ear 4, thereby can adapt to the base of dissimilar porcelain vases.
With reference to figure 4 second anchor ear is described, second anchor ear is the chorista of two symmetries, each chorista of second anchor ear is extended with the strut that has screwed hole 11 in the end respectively, the top step 14 (Fig. 7 illustrates) of second cat ladder 5 can be connected in the screwed hole 11 by bolt, thereby realizes being connected of second cat ladder 5 and second anchor ear.The top of two second cat ladders 5 all is connected with second anchor ear by identical connected mode.
As for removably connecting of the pillar of first cat ladder 1 and isolating switch, can be accomplished in several ways, for example, can realize by the 3rd anchor ear 3, than first anchor ear 4 and second anchor ear, the 3rd anchor ear 3 is an one-sided configuration, that is, the 3rd anchor ear 3 has only a side bottom of first cat ladder 1 and the 3rd anchor ear 3 and first cat ladder 1 to be installed for removably connecting.
Fig. 5 shows the enlarged drawing of A portion among this Fig. 1, show second cat ladder 5 vertical terraced bar be connected in two horizontal steps between this vertical terraced bar.
By foregoing description as can be known, jungle gym is owing to use anchor ear to be connected with isolating switch, so the jungle gym floor space after the assembling is less, and, indulge the above as can be known, first anchor ear 4, second anchor ear, the 3rd anchor ear 3 itself are can realize holding tightly action for separable structure and by bolt, first cat ladder 1 can split from first anchor ear 4, the 3rd anchor ear 3, equally, two second cat ladders 5 all can split from first anchor ear 4 and second anchor ear, so structure of the present utility model is easy to assembling and carries, and can reduce the repair time.In addition, need not climb porcelain vase by means of jungle gym of the present utility model and just can overhaul, and,, make power supply quality that better assurance be arranged so reduce the power failure area owing to do not re-use the job that requires special skills car to isolating switch.
Folding shelf structure isolating switch of the present utility model is the GW6 Series Switch-disconnector.
Although the utility model is illustrated with reference to accompanying drawing and preferred embodiment, obviously, for a person skilled in the art, under the prerequisite that does not deviate from spirit and scope of the present utility model, can make various changes and variation to the utility model.Various change of the present utility model, the content that changes by appending claims and equivalent thereof contain.
