Abstract
The utility model discloses a spiral fuse protective device including a protective cover adapted to the base of a spiral fuse. A connecting part is arranged on the protective cover, and a fixing device fixing the protective cover relative to the base of the spiral fuse is arranged on the connecting part. The protective device is simple in structure and convenient in use, the protective cover covers the base of the spiral fuse to prevent operators from contacting with the metal part exposed on the base and further prevent the operators from the danger of electric shock; meanwhile, the fixing device fixes the protective cover well to prevent the protective cover from accidentally coming off; moreover, the protective cover can prevent screws from falling into the base of the spiral fuse while the operators replaces an electric energy meter, thereby preventing the generation of danger.
Description
Technical field
The utility model relates to the screw type fuse protective device.
Background technology
Screw type fuse is used for overload and the short-circuit protection of electric equipment, is comprised of porcelain cap, fuse tube, guard circle and base four parts.Fuse and quartz sand are housed in the fuse tube, are stamped indicating device on the pipe, whether indicating fuse fuses.
At present when power failure attaching electric energy meter, after pulling out screw type fuse, spiral upper pile crown is still charged, and be that a metal part above the exposed charged position base also is charged, accidentally run into the danger that just might cause electric shock, thus very dangerous, and also the opening diameter of screw type fuse is larger, screw, nut also are easy to drop in the screw type fuse base when changing electric energy meter, cause unnecessary trouble.
The utility model content
The purpose of this utility model is to provide the screw type fuse protective device, can effectively solve existing screw type fuse base exposed problem of easily getting an electric shock outside when changing electric energy meter.
In order to solve the problems of the technologies described above; the utility model is achieved through the following technical solutions: the screw type fuse protective device; comprise the over cap suitable with the screw type fuse base; described over cap is provided with connecting portion, and described connecting portion is provided with over cap and the relatively-stationary fixture of screw type fuse base.
Preferably, described fixture is included in that the connecting portion front end offers is connected the suitable draw-in groove of wire with the screw type fuse base; Increase the contact-making surface of protective device and screw type fuse, so that protective device difficult drop-off in use.
Preferably, the top of described connecting portion also has the translot that intersects with draw-in groove, is provided with cross bar in the described translot, and the end switching of described cross bar is in translot, and the distance of described cross bar bottom draw-in groove is connected the diameter of wire greater than the screw type fuse base; The increase cross bar cooperates the risk that protective device and screw type fuse base break away from when further reducing use with translot.
Preferably, an end of described cross bar is transferred in translot by rotating shaft; Make simple and conveniently, reduce difficulty of processing.
Compared with prior art; the utility model has the advantages that: this apparatus structure is simply easy to use; utilize over cap that the screw type fuse base is covered; the operator just can not touch metal part exposed on the base; also just avoided the danger of getting an electric shock, fixture is well fixed over cap simultaneously, prevents the over cap accidental; and over cap can also prevent that workman's screw when changing electric energy meter from falling in the screw type fuse base, avoids cause danger.

Embodiment
Consult Fig. 1; Fig. 2 is the embodiment of the utility model screw type fuse protective device; the screw type fuse protective device; comprise the over cap 1 suitable with the screw type fuse base; described over cap 1 is provided with connecting portion 2; described connecting portion 2 is provided with over cap 1 and the relatively-stationary fixture of screw type fuse base; described fixture is included in that connecting portion 2 front ends offer is connected the suitable draw-in groove of wire 3 with the screw type fuse base; the top of described connecting portion 2 also has the translot 4 that intersects with draw-in groove 3; be provided with cross bar 5 in the described translot 4; the one end switching of described cross bar 5 is in translot 4; described cross bar 5 and the distance of draw-in groove 3 bottoms are connected the diameter of wire greater than the screw type fuse base, an end of described cross bar 5 by rotating shaft 6 switchings in translot 4.
Over cap 1 is covered on the screw type fuse base; the wire that is connected with the screw type fuse base is stuck in the draw-in groove 3; be buckled in the translot 4 by cross bar 5 again, can prevent effectively that over cap 1 and screw type fuse base from separating, thus the safety of protection workman when changing ammeter.
The above only is specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
