Abstract
The utility model discloses a pair of tongs for a secondary fuse, which comprises a pair of tong heads and a pair of tong handles, wherein, the two tong handles are connected in a rotating manner through a rotating shaft, clamping groove ports are formed correspondingly on the tong heads and/or the tong handles, and the included angle between the axis of the clamping groove ports and the rotatingshaft ranges from 0 to 30 degrees. The solution to the problems arising from the exchange of the secondary fuse used in the practice of electricity transformation is to equip the two ends of each tonghead as well as each tong handle with clamping groove ports, so that the two ends can be used in clamping the secondary fuse. In the light of the presence of 1-5A small secondary fuses, the tongs canbe vertically placed in a fuse box, with one end of each tong handle to be arc-shaped in the vertical direction so as to vertically clamp the fuse, and the other end to be flattened so as to horizontally clamp the fuse. The utility model is simple in structure, realizes rapid assembly and taking out, improves the work efficiency, and greatly raises the safety and the operability.
Description
Technical field
The utility model relates to the low-voltage electrical apparatus field of tool, especially relates to a kind of replacing insurance with clamping.
Background technology
The substation secondary insurance is more, not of uniform size, the material difference, model is more, there is not specific purpose tool when getting carrying out secondary insurance dress, if tape insulation gloves operation, when directly getting the secondary insurance with the hand dress, because hand is nearer apart from live part, perhaps because a plurality of guard tracks from too small, thereby are difficult to take off insurance, and cause easily and get an electric shock and short circuit, there is potential safety hazard, easily human body produced injury; If putting on insulating gloves operates, because of insulating gloves is thicker, point the dumb inconvenient operation that causes, especially some embedded mini fuses being difficult to contact can't take off, and influences operating process, makes the operating time long.
The utility model content
The purpose of this utility model is to provide a kind of pliers of fast changeable insurance, and pliers is flexible to operation and insulation safety in narrow space.
The technical solution of the utility model is:
The secondary insurance comprises a pair of binding clip and pincers handle with pincers, is rotationally connected by rotating shaft between two pincers handles, and correspondence is provided with the draw-in groove mouth on described binding clip and/or the pincers handle.
Angle is the 0-30 degree between the axis of described draw-in groove mouth and the rotating shaft.
The axis of described draw-in groove mouth and shaft parallel.
Angle is the 60-90 degree between the axis of described draw-in groove mouth and the rotating shaft.
The axis of described draw-in groove mouth is vertical with rotating shaft.
Described draw-in groove mouth and protective tube shape are suitable.
Described draw-in groove mouth is an arc.
Described binding clip and pincers handle adopt insulating material.
The utility model at changing the problem that exists in the secondary insurance, all is provided with draw-in groove mouth with binding clip and pincers handle two ends from the power transformation reality of work, so just can use at two ends the insurance of gripping secondary; Considered some 1-5A young waiters in a wineshop or an inn time insurance, vertically be placed in the safety box that pincers handle one end vertical direction is that arc is realized the vertical folder danger of going bail for, the other end is designed to flat mouthful can horizontal gripping.Insulating material such as that material can adopt is wooden, resin, fiberglass, whole insurance pincers length is controlled between 15-20 centimetre, and is suitable to make things convenient for staff to be operating as.The utility model is simple in structure, has realized that fast quick-mounting gets, and has improved operating efficiency, has improved fail safe and operability greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the structural representation of one-sided binding clip and plumbous handle;
Fig. 4 is the B-B sectional view of Fig. 3.
Embodiment
Shown in Fig. 1,3, the utility model comprise left and right sides binding clip 1,2 and about pincers handle 7,8, between the left side pincers handle 7,8 by rotating shaft 9 connections.Binding clip 1 top, a left side is provided with the draw-in groove mouth 5 of indent, and right binding clip 2 also correspondence is provided with draw-in groove mouth 5, and the shape of draw-in groove mouth 5 and the profile of protective tube are suitable.Draw-in groove mouth 5 is an arc, and the axis of draw-in groove mouth 5 is parallel with axle 9.
About pincers handle 7,8 bottoms be equipped with draw-in groove mouth 6, draw-in groove mouth 6 concaves, two draw-in groove mouths 6 are oppositely arranged, draw-in groove mouth 6 is an arc.The shape and the protective tube of draw-in groove mouth 6 are suitable, and the axis of draw-in groove mouth 6 is vertical with axle 9.
Pincers handle 7,8 opens left and right sides binding clip 1,2 about strikeing with the hand open during use, near protective tube, clamps the circumference of protective tube then with draw-in groove mouth 5, protective tube can be extracted.Open binding clip 1,2 conversely, pincers handle 7,8 is opened, clamp the upper end of protective tube, protective tube can be pulled out.
Left and right sides binding clip 1,2 and about pincers handle 7,8 all adopt insulating material such as wooden, resin, fiberglass to make, can effectively guarantee operating personnel's safety.In addition also only draw-in groove mouth 5,6 adopt insulating material to make, draw-in groove mouth 5 and 1,2 insulation of left and right sides binding clip also can guarantee insulation property.In addition, because the protective tube position circuit in the power transformation cabinet, power transformation case is more, the space is narrow and small, therefore can with left and right sides binding clip 1,2 and about pincers handle 7,8 make long narrow shape, so just can more easily it be stretched into and taking-up or installation insurance pipe.
Need to prove at last: draw-in groove mouth 5 axis can also with the axle 9 not parallel and 0-30 degree that form an angle, the axis of draw-in groove mouth 6 also can with axle 9 out of plumb and the 60-90 degree that forms an angle, draw-in groove mouth 5 and 6 still can be clamped protective tube easily, can remove to clamp protective tube at a slant, can be more convenient when hand-held; Also draw-in groove mouth 5 or draw-in groove mouth 6 can only be set, save draw-in groove mouth 6 or draw-in groove mouth 5, so approximate variation also drops within the protection range of the present utility model.
