Description
Technical field
The utility model relates to electric elements technical field, is specifically a kind of fuse plug.
Background technology
Fuse plug is the critical piece of fuse, in order to short circuit or electric current excessive time cut off circuit, to play a protective role to equipment.The fuse plug of prior art comprises plug base, the axle center place of plug base be provided with run through the upper and lower both ends of the surface of plug base and can be axially movable striker, the upper end of plug base is provided with rotary handle, rotary handle has mounting panel, the outer wall of mounting panel is provided with dropout bent plate, dropout bent plate is movably set with striker baffle plate, the inner of striker baffle plate to be stretched in rotary handle and is oppositely arranged with striker, outer end is stretched out outside rotary handle, and the two ends of striker baffle plate bent plate of can threading off is that fulcrum is lifted up up and down.Generally, fuse plug is all laterally place, when being short-circuited or electric current is excessive, fuse work will be excited, by striker by the inner of striker baffle plate upwards jack-up, meanwhile, the outer end of striker baffle plate is lifted up downwards, disconnects, cut off circuit with this with the switch connector be connected.When circuit recovers normal, striker baffle plate can automatically reset again.But the fuse plug of this kind of structural design is only applicable to horizontal placement, when vertically placing, due to Action of Gravity Field, striker baffle plate cannot automatically reset, and needs hand-reset, very inconvenient.And in some power distribution cabinets, in order to rationally distributedization, need fuse plug vertically to place, this is just badly in need of when one is vertically placed, and striker baffle plate still can automatically reset fuse plug.
In order to solve the problem, this case is life therefrom.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and when providing one vertically to place, striker baffle plate still can automatically reset fuse plug.
To achieve these goals, the technical solution of the utility model is as follows: a kind of fuse plug, comprise plug base, the axle center place of plug base be provided with run through the upper and lower both ends of the surface of plug base and can be axially movable striker, the upper end of plug base is provided with rotary handle, rotary handle has mounting panel, the outer wall of mounting panel is provided with dropout bent plate, dropout bent plate is movably set with striker baffle plate, the inner of striker baffle plate to be stretched in rotary handle and is oppositely arranged with striker, outer end is stretched out outside rotary handle, the two ends of striker baffle plate bent plate of can threading off is that fulcrum is lifted up up and down, the sidewall of described dropout bent plate is provided with reduction torsion spring, the outer wall of wherein a torque arm and the mounting panel of reduction torsion spring offsets, the upper surface another torque arm and striker baffle plate being positioned at rotary handle offsets.
Two, the left and right sidewall of described dropout bent plate is provided with reduction torsion spring.
After adopting technique scheme, the utility model compared with prior art, have the following advantages: the utility model fuse plug, striker baffle plate can automatically reset under the effect of reduction torsion spring, be not only applicable to horizontal placement, be also applicable to vertical placement, structure is simple simultaneously, easy to use, highly versatile.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model fuse plug.
Shown in figure: 1, plug base 2, striker 3, rotary handle 4, mounting panel 5, dropout bent plate 6, striker baffle plate 7, reduction torsion spring.
Embodiment
Below by drawings and Examples, the utility model is further elaborated.
As shown in Figure 1: a kind of fuse plug, comprises plug base 1, the axle center place of plug base 1 be provided with run through plug base about 1 both ends of the surface and can be axially movable striker 2.The upper end of plug base 1 is provided with rotary handle 3, and rotary handle 3 has mounting panel 4.The outer wall of mounting panel 4 is provided with dropout bent plate 5, dropout bent plate 5 is movably set with striker baffle plate 6.The inner of striker baffle plate 6 to be stretched in rotary handle 3 and is oppositely arranged with striker 2, and outer end is stretched out outside rotary handle 3, and the two ends of striker baffle plate 6 bent plate 5 of can threading off is lifted up up and down for fulcrum.More than be prior art, primary object of the present utility model is: the sidewall of dropout bent plate 5 is provided with reduction torsion spring 7.The outer wall of wherein a torque arm and the mounting panel 4 of reduction torsion spring 7 offsets, the upper surface another torque arm and striker baffle plate 6 being positioned at rotary handle 3 offsets, with this, downward pressure is applied all the time to the inner of striker baffle plate 6, ensure that striker baffle plate 6 can automatically reset smoothly after being backed down by striker 2 under this pressure effect.
In the present embodiment, two, the left and right sidewall of dropout bent plate 5 is provided with reduction torsion spring 7.Design like this, two reduction torsion springs 7 can apply downward pressure to the both sides of striker baffle plate 6 respectively simultaneously, and make the stressed more even of striker baffle plate 6, reset effect is better.
The utility model fuse plug, striker baffle plate 6 can automatically reset under the effect of reduction torsion spring 7, is not only applicable to horizontal placement, is also applicable to vertical placement simultaneously, and structure is simple, easy to use, highly versatile.
Upper described foundation embodiment is enlightenment, and by above-mentioned description, relevant staff in the scope not departing from this utility model thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its scope protected according to right.
