Utility model content

The purpose of this utility model is to provide a kind of box body structure of bar shaped fuse disconnecting switch, and its advantage is to realize The anti-operating effect of link gear.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of bar shaped fuse type The box body structure of disconnecting switch, including the base and stacker that cooperate, the stacker is provided with several and arranges successively It is spacing renovate, spacing renovating is provided with for being hinged foot with stacker is hinged, and spacing the renovating is hinged with tumbler； It is two neighboring spacing when renovating fastening, the previous spacing tumbler renovated snap into it is latter it is spacing renovate be hinged on foot simultaneously Form rotary spacing.

By above-mentioned technical proposal, three spacing renovating are arranged on stacker successively, and pass through tumbler and be hinged foot Rotational restraint is established, needs to stir the tumbler releasing adjacent spacing rotational restraint renovated during operation；Thereby serve to anti-error The spacing effect renovated is opened in operation；Meanwhile, the structure of similar handle is formed after tumbler upset, is facilitated operator to pull and is held Joint chair, and after assembling is finished, then tumbler can be drawn in, reduce the space shared by overall structure.

This utility model is further arranged to：Spacing the renovating is provided with locating piece, and the locating piece is provided with catching groove, The tumbler is provided with for inserting the button block of catching groove.

By above-mentioned technical proposal, stability of the tumbler in current location is improved with catching groove with button block, is reduced The situation that tumbler surprisingly swings；Each tumbler is relatively stable after opening, and facilitates operator to open tumbler successively.

This utility model is further arranged to：Spacing the renovating is provided with flexure strip, and flexure strip is supplied on the locating piece The promotion groove of insertion.

By above-mentioned technical proposal, flexure strip can promote locating piece to be displaced outwardly, and remain out locating piece and mobile become Gesture, therefore button block can insert catching groove by way of elasticity extruding, increased both cooperation compactnesss, while promoting positioning Block can release the matching relationship of catching groove and button block, i.e., now tumbler is rotatable.

This utility model is further arranged to：The locating piece is provided with two card bases, and the end of two card bases is dorsad turned over Folding forms snap fit.

By above-mentioned technical proposal, locating piece is realized snapping connection by two card bases, and the structure is easy to assembly, without the need for volume Outer instrument.

This utility model is further arranged to：Spacing the renovating is provided with arc convex, and the stacker is provided with and supplies arc The raised embedded groove of shape.

By above-mentioned technical proposal, it is spacing renovate between stacker except articulated structure be also provided with arc convex with it is recessed Groove, forms the spacing both sides positioning renovated after arc convex embedded groove, and now spacing to renovate relative stacker relatively stable.

This utility model is further arranged to：Spacing the renovating is provided with side block edge, and the tumbler is provided with and supplies side Interior lining panel of the gear along clamping, the tumbler are provided with for contradicting the outer baffle block on side block edge near the side of interior lining panel.

By above-mentioned technical proposal, when rotating, in side block along interior synchronous axial system, side block is along by interior for interior lining panel for tumbler The swing that liner plate reduces tumbler is interval, improves the rotational stability of tumbler, while outer baffle block is contradicted to side block after, The rotation of tumbler is limited, i.e., the slewing area of tumbler is controlled in suitable interval, reduces the destruction of tumbler inordinate rotation The situation of catching groove on locating piece.

This utility model is further arranged to：The tumbler is provided with steering fixed block at its articulated position, described Spacing renovating is provided with for turning to the first steering groove, the second steering groove that fixed block is inserted, and first turns to groove and second turns to groove Between be provided with for turn to fixed block climbing slope.

By above-mentioned technical proposal, tumbler can keep two to specify steering by turning to fixed block on spacing renovating, The first steering groove is snapped in when fixed block is turned to, tumbler remains out the state that can be lifted after stirring, snapped in when fixed block is turned to After second turns to groove, tumbler is drawn in stacker.

This utility model is further arranged to：Spacing the renovating is provided with gib block, and the stacker is provided with for leading To the locating slot of bar positioning.

By above-mentioned technical proposal, the spacing rotational band action-oriented bar renovated is rotated, if two adjacent spacing are renovated Centrage on the same line, then gib block position centered on the position in locating slot, now gib block can help operator Member understands the installation of the spacing fuse-link renovated whether off center line, and when fuse-link off center line, gib block then exists Offset in locating slot, now the deviation of fuse-link angle of arrival, may cause the electrical connection contact surface of contact knife imperfect, thus make Into the inaccurate of melt disconnection；The installation situation of current fuse-link can be learnt by gib block in external observation.

This utility model is further arranged to：The spacing both sides renovated are provided with card edge, and the both sides of the stacker set There is the exterior bayonet slot along insertion for card.

By above-mentioned technical proposal, card is carried along causing spacing renovating that good fixed clamp effect is realized on stacker The high spacing mounting stability renovated.

This utility model is further arranged to：The stacker is provided with lock ear, and spacing the renovating is provided with for matching somebody with somebody Close the locked groove that lock ear forms groove.

By above-mentioned technical proposal, after lock ear and locked groove, it is available for padlock to install, realizes the spacing lock for renovating relative stacker It is fixed；Thus padlock is hung up in each spacing renovating, be effectively reduced the spacing unexpected folding situation renovated.

In sum, this utility model has the advantages that：1st, it is spacing to renovate between stacker with multiple anti- The structure of maloperation, improves safety；2nd, tumbler and it is spacing renovate between have multiple location structures, improve tumbler Structural stability under different angles.
