In prior art, the structure of low voltage fuse type isolating switch is primarily of insulation column moved end, the quiet end of insulation column, dynamic touch panel, static contact panel, quiescent contacting knife, movable touch knife, insulated tension pole and fuse piece composition.Insulation column moved end and the quiet end of insulation column keep certain distance to be arranged on base, dynamic touch panel and static contact panel are arranged on the top of insulation column moved end and the quiet end of insulation column respectively, one end of quiescent contacting knife is articulated on static contact panel, the other end of quiescent contacting knife is connected with movable touch knife by insulated tension pole, realizes electrical connection between quiescent contacting knife and movable touch knife by fuse piece.
During use, rotate quiescent contacting knife, movable touch knife is turned to thereupon and contacts with dynamic touch panel, namely combined floodgate realizing circuit is connected, otherwise rightabout rotates quiescent contacting knife, and movable touch knife is separated with dynamic touch panel, namely opens a sluice gate realizing circuit and disconnects.
Existing low voltage fuse type isolating switch, does not generally have self-locking mechanism, there is the risk automatically falling separating brake during use.Therefore, the structure of the present inventor to existing low voltage fuse type isolating switch is improved, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of low-tension fuse isolating switch self-locking drop-proof buckle device, produces the risk automatically falling separating brake during to avoid closing a floodgate.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of low-tension fuse isolating switch self-locking drop-proof buckle device, comprises insulation column moved end, the quiet end of insulation column, dynamic touch panel, static contact panel, quiescent contacting knife, movable touch knife, insulated tension pole and fuse piece; The bottom of insulation column moved end and the quiet end of insulation column is arranged on base, dynamic touch panel and static contact panel are arranged on the top of insulation column moved end and the quiet end of insulation column respectively, one end of quiescent contacting knife is articulated on static contact panel, the other end of quiescent contacting knife is connected with movable touch knife by insulated tension pole, realizes electrical connection between quiescent contacting knife and movable touch knife by fuse piece; Dynamic touch panel also fixedly mounts hook, movable touch knife also fixedly mounts draw ring, draw ring pivotally installs locking hook by pivot, one end that locking is hooked in pivot forms hook, locking is hooked between the other end of pivot and draw ring and installs extension spring, coordinates and makes isolating switch self-locking during combined floodgate under the effect of extension spring by the hook of locking hook with hook.
The hook cooperation place of described hook and locking hook is designed in skewed.
The below of described draw ring and the top of locking hook all form grab, and the two ends of extension spring are hooked on grab respectively.
The middle part of described draw ring also forms gear grain, and during combined floodgate, the base of locking hook is against on gear grain.
After adopting such scheme, the utility model is because add hook, draw ring, locking hook and spring, when isolating switch is in closing position, locking hook catches on hook, prevent from threading off by spring pulling locking hook, realize automatically locking, thoroughly elimination is energized, and operation breaker in middle falls automatically, separating brake is dangerous, when sub-switching operation by pulling locking hook can automatic unlocking, handling safety be reliable.
Accompanying drawing explanation
Fig. 1 is improvement part decomposing schematic representation of the present utility model;
Fig. 2 is "on" position schematic diagram of the present utility model;
Fig. 3 of the present utility modelly opens a sluice gate view.
Label declaration
Insulation column moved end 1, the quiet end 2 of insulation column, dynamic touch panel 3, static contact panel 4, quiescent contacting knife 5, movable touch knife 6, insulated tension pole 7, fuse piece 8, base 9, hook 10, draw ring 11, grab 111, gear grain 112, pivot 12, locking hook 13, hook 131, grab 132, extension spring 14.
Embodiment
As shown in Figure 1 to Figure 3, a kind of low-tension fuse isolating switch self-locking drop-proof buckle device that the utility model discloses, comprises insulation column moved end 1, the quiet end 2 of insulation column, dynamic touch panel 3, static contact panel 4, quiescent contacting knife 5, movable touch knife 6, insulated tension pole 7 and fuse piece 8.The bottom of insulation column moved end 1 and the quiet end 2 of insulation column is arranged on base 9, and dynamic touch panel 3 and static contact panel 4 are arranged on the top of insulation column moved end 1 and the quiet end 2 of insulation column respectively.One end of quiescent contacting knife 5 is articulated on static contact panel 4, and the other end of quiescent contacting knife 5 is connected with movable touch knife 6 by insulated tension pole 7, realizes electrical connection between quiescent contacting knife 5 and movable touch knife 6 by fuse piece 8.
Dynamic touch panel 3 of the present utility model also fixedly mounts hook 10, movable touch knife 6 also fixedly mounts draw ring 11, draw ring 11 pivotally installs locking hook 13 by pivot 12, locking hook 13 forms hook 131 in one end of pivot 12, and locking hook 13 installs extension spring 14 between the other end and draw ring 11 of pivot 12.Conveniently extension spring 14 is installed, and the below of draw ring 11 forms grab 111, and the top of locking hook 13 forms grab 132, and the two ends of extension spring 14 are hooked on grab 111 and 132 respectively.In order to make operation more smooth and easy, hook 10 and hook 131 cooperation place of locking hook 13 design in skewed by the utility model.In order to make self-locking action more accurately put in place, the middle part of the utility model draw ring 11 also forms gear grain 112, and during combined floodgate, the base of locking hook 13 is against on gear grain 112.
When the utility model closes a floodgate and uses, rotate quiescent contacting knife 5, movable touch knife 6 is turned to thereupon contact with dynamic touch panel 3, namely combined floodgate realizing circuit is connected, meanwhile, the hook 131 of locking hook 13 hooks on hook 10, prevents locking hook 13 from threading off under the effect of extension spring 14, make isolating switch automatic blocking, thoroughly elimination is energized, and operation breaker in middle falls automatically, separating brake is dangerous.During sub-switching operation, by pulling locking hook 13, making hook 131 depart from hook 10 and unlocking, then rotating quiescent contacting knife 5, movable touch knife 6 is rotated thereupon and is separated with dynamic touch panel 3, namely complete separating brake, realizing circuit disconnects.
These are only specific embodiment of the utility model, the restriction not to protection range of the present utility model.All equivalent variations done according to the mentality of designing of this case, all fall into the protection range of this case.
