Description
Technical field
The utility model relates to a kind of electric equipment, relates in particular to a kind of specific purpose tool for the loading and unloading high-tension fuse.
Background technology
At present in process of production, during the on-load switch fuse melting, do not change the specific purpose tool of insurance, change insurance at need, when resuming production fast, be subjected to the space narrow and small, tube wall heating, adhesion, the influence of factors such as operations staff's both hands power size, changing insurance wastes time and energy, and incurs loss through delay and produces.
Change the problem that high-tension fuse exists four need to solve in accident treatment: (1) high-tension fuse is in long and narrow cabinet, and the space is narrow and small, and the people is bad firmly when changing insurance; Heating when (2) insurance is because of the too high fusing of electric current, the tube wall temperature height scalds one's hand when changing fuse; The fuse porcelain bushing might burst when (3) running into big electric current, when changing high-tension fuse, may injure staff's hand.(4) good for guaranteeing contact, the jump ring snap-in force in the fuse sockets draw-in groove is very big, when changing insurance, if staff's arm strength is not enough, is difficult to take out or fuse is installed, and brings great inconvenience to work.
Chinese patent publication No. CN202443935U discloses a kind of instrument of changing fuse, comprise and compress end cap, the nearly clasp of pressure is installed in the left and right sides that compresses end cap, press the lower end of nearly clasp to be buckled on the clasp head, the described both sides, front and back that compress end cap are provided with screw hole, described clasp head is on the crimping plate, and the crimping plate is formed by connecting by bolt by two semicircular circles.The instrument of this replacing fuse need be installed on the fuse, complex operation.
The utility model content
The purpose of this utility model is to provide a kind of easy to operate specific purpose tool that is used for the loading and unloading high-tension fuse, to solve the problem that exists in the background technology.
To achieve these goals, the technical scheme that the utility model is used for the specific purpose tool of loading and unloading high-tension fuse is: a kind of specific purpose tool for the loading and unloading high-tension fuse, comprise action bars, one end of described action bars is connected with operating portion, described operating portion comprises a connecting rod, the two ends of connecting rod are connected with outer snap ring and interior shackle respectively, described outer snap ring and the coaxial setting of interior shackle.The design philosophy of this technical scheme is: shackle in the design one outer snap ring and, during the dismounting high-tension fuse, after earlier the bottom of high-tension fuse being placed the installation site, adjust the connecting rod direction by the rotary manipulation bar, make the wild card latch closure in the outside, high-tension fuse lower end, it is inboard that interior shackle is buckled in the high-tension fuse upper end, pulls action bars, interior shackle applies outside pulling force to the high-tension fuse upper end, and high-tension fuse is namely detachable; When high-tension fuse is installed, then adjust the connecting rod direction by the rotary manipulation bar, make the wild card latch closure in the outside, high-tension fuse upper end, interior shackle is buckled in inboard, high-tension fuse lower end, pull action bars, outer snap ring applies inside thrust to the high-tension fuse upper end, and high-tension fuse can be in place, and is easy to operate.
As preferably, described connecting rod is vertical with action bars.
As preferably, an end of described connecting rod is connected with an end of action bars.According to lever principle, more than two purpose be to make operating personnel's application of force minimum, best results.
As preferably, the axis of described outer snap ring is vertical with action bars.
As preferably, described outer snap ring is a smaller part annulus, and described outer snap ring protrudes towards the direction of action bars.The outer snap ring of a smaller part annulus mainly is be used to applying inside thrust.
As preferably, described in shackle be more than half annulus, described in shackle protrude towards the direction vertical with action bars.The outer snap ring of more than half annulus mainly is be used to applying outside pulling force.
As preferably, an end of described connecting rod is connected with the mid point of outer snap ring.
As preferably, the other end of described connecting rod is connected with an end of interior shackle.
As preferably, described action bars is collapsible.Some space, high-tension fuse place is narrow and small, and action bars is collapsible and launch to be applicable to multiple occasion that versatility is stronger.
The beneficial effect that the utility model is used for the specific purpose tool of loading and unloading high-tension fuse is: should be used for easy to operate, the highly versatile of specific purpose tool of loading and unloading high-tension fuse, and improve operating efficiency.
