Embodiment
Referring to figs. 1 through Fig. 4, the utility model outdoor vacuum circuit breaker embodiment is described further.
A kind of outdoor vacuum circuit breaker, comprise metal framework 1, spring 7 operating mechanism 2, vacuum interrupter 3, described metal framework 1 side is vertically provided with the first insulation column 4 and the second insulation column 5, described first insulation column 4 is provided with the first mount pad 41 away from one end of metal framework 1, described second insulation column 5 is provided with the second mount pad 51 away from one end of metal framework 1, described second installs on vertical projection and the first mount pad 41, described vacuum interrupter 3 one end is fixedly connected with the first mount pad 41, vacuum interrupter 3 other end is fixedly connected with the second mount pad 51, described metal framework 1 upper end is provided with spring 7 operating mechanism 2, described spring 7 operating mechanism 2 one end is connected with the second mount pad 51, described metal framework 1 is longitudinally provided with and connects chute 11, described first insulation column 4 is flexibly connected with metal framework 1, one end that described first insulation column 4 is connected with metal framework 1 is link 42, described metal framework 1 is provided with the adjusting device 6 that adjustable link 42 slides up and down in connection chute 11.
Vacuum interrupter 3, in the process used, be arranged on the first mount pad 41 and the second mount pad 51, the then excess of stroke scope of operating spring 7 operating mechanism 2 by the utility model, allows this use is novel can normally work.When this use is novel changed different operational environments or needed to use the vacuum interrupter 3 of different length time, need disassembling hard-wired vacuum interrupter 3 safety before.Then the height of link 42 in connection chute 11 of the first insulation column 4 is just adjusted by adjusting device 6, thus directly change the air line distance of the first mount pad 41 and the second mount pad 51, in debugging after corresponding height, just can being arranged on the correct stability and safety of vacuum interrupter 3 needing to install on the first mount pad 41 and the second mount pad 51.The utility model, has simple to operate, the advantages such as usage range is extensive, has powerful environmental suitability and actual practicality.
Described adjusting device 6 comprises threaded post 61 and the corresponding nut 62 of threaded post 61, regulating tank 12 is provided with above described connection chute 11, described regulating tank 12 is provided with fixed head 13 with being connected between chute 11, described fixed head 13 is provided with the connecting through hole 131 with threaded post 61 matched in clearance, described threaded post 61 runs through connecting through hole 131 and is arranged on fixed head 13, described threaded post 61 is arranged on the one end connected in chute 11 and is fixedly connected with link 42, and described threaded post 61 one end be arranged in regulating tank 12 is rotary with nut 62.When needing the air line distance of adjustment first mount pad 41 and the second mount pad 51, just can direct turn nut 62, thus make to change the air line distance between nut 62 to joint pin 421.And again because fixed head 13 is provided with the connecting through hole 131 with threaded post 61 matched in clearance, like this at the gravity by the first insulation column 4 self, will drive threaded post 61 slide downward easily, until nut 62 is inconsistent with the upper surface of fixed head 13.So just can realize changing the air line distance between nut 62 to joint pin 421, the vacuum interrupter 3 of different length can be conveniently installed.
In the use procedure of reality, nut 62 is just hexagonal nut, in operation, can by the shift length selecting several sides of nut 62 to estimate the first insulation column 4, thus make whole device more intelligent, more convenient to operate convenient.
The joint pin 421 that regulating tank 12 and the effect being connected chute 11 can exchange regulating device 6 and the first insulation column 4 is protected; and regulate the axial length of chute to be greater than the length of threaded post 61; so just can considerably increase the adjustable range of adjusting device 6; also further expand the length range of spendable vacuum interrupter 3, substantially increasing product is adaptability.
Described link 42 comprises joint pin 421 and insulation wrappage 422, described joint pin 421 one end is with to be connected chute 11 inconsistent, joint pin 421 other end is fixedly connected with the first insulation column 4, described insulation wrappage 422 parcel is arranged on joint pin 421 sidewall, and described threaded post 61 is fixedly connected with insulation wrappage 422.Described connection chute 11 is dovetail groove, and described insulation wrappage 422 is with to be connected the sidewall that chute 11 tilts inconsistent.Connecting chute 11 is dovetail groove, and the wrappage 422 that insulate is with to be connected the sidewall that chute 11 tilts inconsistent, so not only can prevent link 42 from departing from and connect chute 11, what allow the first insulation column 4 be connected with metal sales counter is more stable, improve the bonding strength of product, and insulation wrappage 422 there is insulating ceramics to form, like this when ensureing the intensity that insulation wrappage 422 can insulate powerful, have and can have good insulation characterisitic, improve product is fail safe.Joint pin 421 one end, with to be connected chute 11 inconsistent, to be conveniently connected with metal framework 1 inside through joint pin 421.
Described insulation wrappage 422 is fixed with spring 7 away from one end of threaded post 61, and described spring 7 one end is fixedly connected with insulation wrappage 422, the other end of spring 7 be connected chute 11 lower end surface and be fixedly connected with.Described spring 7 is tension spring, like this by nut 62 along threaded post 61 upwards turn time, by the gravity of spring 7 and the first insulation column 4 self, threaded post 61 can be made to glide fast along connecting through hole 131, and nut 62 is inconsistent with fixed head 13 upper surface, facilitate the first insulation column 4 to move down, make adjusting device 6 sensitiveer, the work load of the workman greatly alleviated.And when using, by the effect of spring 7, what the first insulation column 4 can be made to install is more stable, can effectively prevent the first insulation column 4 from shaking in connection chute 11, the more stable and safety that vacuum interrupter 3 can be allowed to install.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
