Abstract

The utility model relates to a fuse box, which is a protection device for breaking current by fusing meltable materials. It comprises a box body, a turntable, a rotating wheel, a spring piece, a fuse and a switch. Wherein, it has two to rotate the support arm to stretch out at least on the carousel, and the fuse twines on the runner, and the duplex winding is on rotating the support arm, with the fuse series connection between two rotation support arms in the power supply line and with electrical apparatus line. The utility model discloses simple structure, convenient to use.

Description

Safety box

The utility model relates to a kind of safety box, belongs to the fusing of fusible material and makes the protective device of current interruptions.

Existing safety box just is connected in series fuse simply between electrical appliance line and supply lines, in case fuse burns, need reinstall, and wastes time and energy, and uses very inconvenient.

The purpose of this utility model is to provide a kind of novel safety box at above-mentioned deficiency of the prior art, and it has advantage easy to use especially, has practical characteristics simple in structure simultaneously.

The purpose of this utility model realizes with following technical scheme: it is made up of box body, rotating disk, runner, spring leaf, fuse, switch, wherein, at least be extended with two rotating support arm on the rotating disk, fuse is wound in runner, and be wire-wrapped on the rotating support arm, it has come down to utilize the fuse between two rotating support arm to be serially connected with supply lines and electrical appliance line, because rotating disk is rotatable, thereby use easily, structure is also simple.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an enforcement illustration of the present utility model.

Fig. 3 is the schematic diagram of rotating support arm 20.

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model is made up of insulation box body 1, insulation rotating disk 4, runner 35, metal spring sheet 19,23, fuse 26, sensitive switch K, wherein, be equipped with the rotation axis 3 of band fitting recess 2 on the box body 1 left part center, be fixed with rotating disk 4 on the rotation axis 3, can install turn-button along the fitting recess 2 of rotation axis 3, rotate can stir rotating disk 4.At least be inlaid with two rotating support arm of stretching out 20,24 in the rotating disk 4, preferably six, being metal material makes, open-minded hole 37 is all arranged on it, in rotating disk 4 bottoms, be fixed with the support 12 in the open-minded hole 13 of band on the box body 1, on box body 1 inwall relative shrinkage pool 11 is arranged with support 12, that is to say that axle 36 is arranged on the runner 35, on the shrinkage pool 11 that axle 36 is supported in box body 1 and the open-minded hole 13 of support 12, like this, fuse 26 can be wound in runner 35, and be wire-wrapped on each rotating support arm, be actually fuse 26 is stuck on the open-minded hole 37 of each rotating support arm.

With rotating

support arm

20,24 opposite positions,

useful screw

18,22 and bearing 17,21 are fixed in the spring leaf 19 on the box body 1,23, rotating

support arm

20,24 whiles and spring leaf 19,23 Elastic Contact, in other words, two adjacent rotating support arm whiles and spring leaf 19 on the rotating disk 4,23 Elastic Contact, have on the box body 1 of spring leaf 19 bottoms and spill hole 16, with spring leaf 19 adjacents, useful screw 14 is fixed in group cutter 15 on the box body 1, be a tip sheet metal, rotating

support arm

20,24, each rotating support arm contacts with group cutter 15 rigidity in other words, so that can pull out the fuses broken end in the open-minded hole 37 of rotating support arm, and drop out along spilling hole 16.

On box body 1 inwall circuit groove 25 is arranged, this circuit groove 25 is the shallow grooves around rotating disk 4, the one end road along the line groove 25 of electrical appliance line 28 is connected in spring leaf 19, one of supply lines 29 is terminated at 1 of K switch, 2 of K switch with spring leaf 23 between be connected by circuit 27 road along the line grooves 25, in fact, be that the fuse between two adjacent rotating support arm is serially connected with supply lines 29 and electrical appliance line 28, when fuse burns, turn rotating disk 4, supply line recloses.

Box body 1 right part also has rotating disk 6, runner 34, spring leaf 7,8, the fuse 33 of the identical and symmetric arrangement of structure, and dial cutter 9, spill hole 10, circuit groove 5 etc., the one end road along the line groove 5 of electrical appliance line 31 is connected in spring leaf 8, one of supply lines 30 is terminated at 3 of K switch, 4 of K switch with spring leaf 7 between be connected by circuit 32 road along the line grooves 5, simultaneously, its operation principle is identical.This is actually two safeties, is applicable to very much the circuit insurance to live wire and zero line.

The utility model is easy to use, and is simple in structure, and very big promotional value is arranged.
