Description
Technical field
This invention relates to a kind of jack box interlocking device, and particularly a kind of jack box interlocking device that is mainly used in various bus duct feed element belongs to power transmission and distribution safe practice field.
Background technology
The bus duct series of products just develop towards the direction of high-performance, high-quality, processing safety, require the performance of its feed element jack box also to trend towards diversification simultaneously, the hommization direction develops.Jack box is as a functional unit of power transmission busbar; In bus duct system, play a part to distribute electric energy; Therefore can frequent contact and operation jack box after the user accomplishes that bus is on-the-spot and installs, for just requiring jack box, the safety that guarantees jack box and operating personnel has reliable design, convenience operation.
Chinese patent number discloses a kind of device for locking busway inserting case for the utility model patent of ZL200820216901.4; This device include through rotating shaft be installed in the clamp on the jack box housing, the lower end of clamp is provided with hook; Hook can be hooked on the ledge at bus groove case edge, and it is the arc guide barrel in the center of circle that the clamp upper end has with the rotating shaft, and the inside portion of arc guide barrel has the location hole of diameter greater than the arc guide barrel width; On the jack box housing, be provided with screwed hole; Be rotary with screw in the screwed hole, the screw leading portion passes arc guide barrel and screws in the screwed hole, and the bar portion of screw is made up of thread segment and step positioning section; The diameter of thread segment is less than the arc guide barrel width, and the diameter of step positioning section is between guide groove width and location hole diameter.Insert realization locking in the location hole through the step positioning section.But this device locking precision is not high; The versatility of the overall dimension of the housing of right various bus ducts is not strong; Need operate two screws respectively during locking, therefore operation is convenient inadequately.
Summary of the invention
Goal of the invention: the objective of the invention is the weak point that exists to prior art, for the bus jack box provides a kind of precision height, highly versatile, jack box interlocking device that reliability is high, easy to operate of locking.
Technical scheme: a kind of jack box interlocking device comprises left jam plate, right jam plate, bearing pin, swivel plate, axle sleeve, gear and shrouding; Bearing pin passes swivel plate, axle sleeve and gear successively and is fixed on the jack box shell through axle sleeve, and bearing pin is fixedly connected with gear with swivel plate; Said left jam plate and right jam plate are separately fixed on the shrouding through screw, and the position of mounting screw is provided with the elongated hole of horizontal direction on left jam plate and the right jam plate; Said left jam plate bottom is provided with left side hook, and top is provided with left tooth bar; Said right jam plate bottom is provided with right hook, and top is provided with right tooth bar; Said left side hook was in sustained height with right hook when left side jam plate and right jam plate were installed on the shrouding; Said left tooth bar and right tooth bar were respectively with gear matched and be horizontally distributed in the gear above and below when shrouding was fixed on the jack box shell.Jack box is opened grafting case lid door when installing with bus, rotate swivel plate; Because bearing pin is fixedly connected with gear with swivel plate, axle sleeve is fixed on the jack box shell, so the driven gear of swivel plate rotates the left and right tooth bar motion on the rotation while driving left and right jam plate of gear; At first rotating swivel plate when bus is installed makes left and right hook separately; Then the part of bus duct edge protuberance is put between the left and right hook; The part that last transmitting gear again closes up left and right hook to block the bus duct edge protuberance realizes the fixed installation of bus duct.The step of dismounting bus duct in contrast.
In order further to improve the reliability of this interlocking device; Said shrouding bottom is respectively equipped with the left notch and the right notch of horizontal direction; Left side jam plate and right jam plate lay respectively between left notch and the right notch, and the width of left and right notch is less than the length of elongated hole on the left and right jam plate.When the motion of operation swivel plate driving left and right jam plate, through its motion of edge limitation of left and right notch, to prevent coming off of misoperation tooth bar.The width of left and right notch and position dimension can be confirmed according to the size of bus duct edge protuberance part and the size of hook.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: 1, the locking precision is high; 2, highly versatile; 3, reliability is high; 4, easy to operate.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in the figure, a kind of jack box interlocking device comprises left jam plate 1, right jam plate 2, bearing pin 3, swivel plate 4, axle sleeve 5, gear 6 and shrouding 7; Bearing pin 3 passes swivel plate 4, axle sleeve 5 and gear 6 successively and is fixed on the jack box shell through axle sleeve 5, and bearing pin 3 is fixedly connected with gear 6 with swivel plate 4; Said left jam plate 1 is separately fixed on the shrouding 7 through screw 8 with right jam plate 2, and the position of mounting screw 8 is provided with the elongated hole of horizontal direction on left jam plate 1 and the right jam plate 2; Said left jam plate 1 bottom is provided with left side hook 11, and top is provided with left tooth bar 12; Said right jam plate 2 bottoms are provided with right hook 21, and top is provided with right tooth bar 22; Left side jam plate 1 is installed in a shrouding said left side of 7 last times hook 11 with right jam plate 2 and is in sustained height with right hook 21; Said left tooth bar 12 cooperated with gear 6 respectively with right tooth bar 22 and is horizontally distributed in gear 6 above and belows when shrouding 7 was fixed on the jack box shell.Jack box is opened grafting case lid door when installing with bus, rotate swivel plate 4; Because bearing pin 3 is fixedly connected with gear 6 with swivel plate 4, axle sleeve 5 is fixed on the jack box shell, so driven gear 6 rotations of swivel plate 4, and the rotation of gear 6 drives the left tooth bar 12 and right tooth bar 22 motions on left jam plate 1 and the right jam plate 2 simultaneously; At first rotating swivel plate 4 when bus is installed makes left side hook 11 and right hook open in 21 minutes; Then the part of bus duct edge protuberance is put between left side hook 11 and the right hook 21; The last swivel plate 4 that rotates again makes left side hook 11 and right hook 21 close up the fixed installation that the part of blocking the bus duct edge protuberance realizes bus duct.The step of dismounting bus duct in contrast.
In order further to improve the reliability of this interlocking device; Said shrouding bottom is respectively equipped with the left notch 71 and right notch 72 of horizontal direction; Left side jam plate 1 and right jam plate 2 lay respectively between left notch 71 and the right notch 72, and the width of left notch 71 and right notch 72 is less than the length of elongated hole on left jam plate 1 and the right jam plate 2.When operation swivel plate 4 drives left jam plate 1 and 2 motions of right jam plate, through its motion of edge limitation of left notch 71 and right notch 72, to prevent coming off of misoperation tooth bar.The width of left side notch 71 and right notch 72 and position dimension can be confirmed according to the size of bus duct edge protuberance part and the size of hook.
