Description

Fuse locking device

The utility model relates to a kind of electric product, is meant a kind of fuse locking device used in everyday especially.

At present general home dwelling is equipped with fuse box, its structure is respectively equipped with two screws usually on base plate, be entangled in two ends of fuse on the shank of screw respectively, tightening screw then fixes fuse, the fuse holder assembly of this structure uses pretty troublesome, simultaneously through after a while use, the screw thread of screw often has loosening or wearing and tearing, fixed effect is bad, increased the resistance that connects, easily made the fuse loss with the screw junction, and then make fuse and screw loosening, vicious circle is finally easily blown.Other has a kind of home-use fuse holder assembly is that fuse is inserted between base plate and the hold-down screw end face, tightens screw and fixing fuse, and it is higher that its shortcoming is still contact resistance, easily makes fuse loosening, and trouble is installed.

Goal of the invention of the present utility model is to disclose a kind of installation insurance silk fuse locking device easily.

Realize that technical solution of the present utility model is as follows, be provided with fixed board 2 in the both sides of base plate 1, on the through hole of two fixed boards 2, be provided with a fixed leg 3, one end of fixed leg 3 is a handle 4, there is half garden shape gap 5 at fixed leg 3 middle parts, and the groove 6 in approximate 2 half gardens, a cross section is arranged on the base plate relative with gap 5.Fuse is inserted in gap 5 and the groove 6 common approximately circular openings that constitute, handle 4 is rotated to an angle, there is not the part of opening just fuse to be compressed and fixes on the fixed leg 3, when blown fuse will be changed, only need rotary handle make gap 5 relative, then can take out fuse and change with groove 6.

The utility model is easy to use compared to prior art, and simple in structure, need not any instrument and then can change, and degree of blocking is good simultaneously, and contact resistance is less, has improved the useful life of product.

Provide structure of the present utility model in detail below in conjunction with drawings and Examples.

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

Fig. 2 is the vertical view of Fig. 1.

See also Fig. 1 and Fig. 2, structure of the present utility model is: be provided with in the both sides of base plate 1 and be fixed on plate 2, fixedly be provided with a fixed leg 3 on the through hole of mainboard 2 two, one end of fixed leg 3 is a handle 4, there is half garden shape gap 5 at fixed leg 3 middle parts, the groove 6 that approximate half garden, one cross section is arranged on the base plate relative with gap 5, fuse inserts in the hole of the relative and formation of gap 4 and groove 5, rotary handle and fuse is fixed, can better fix the fuse of various diameters for making the utility model, for slipping over, the curve garden crosses between the edge of described gap 5 and the fixed leg body, the angle of fixed leg rotation is big more like this, and the fixed leg outer surface is more little to the distance of groove 6 bottoms.For suitably increasing the pressure between fixed leg 5 and the groove, be provided with a reed at channel bottom, fuse places on the reed and the post that is fixed compresses.Be the convenient fuse that inserts various diameters, the openend of groove is big, and is contracted to the other end of groove gradually.
