Abstract
The utility model discloses a dual -power switch's moving contact positioner, including the casing, characterized by: be equipped with the dysmorphism piece in the casing, dysmorphism piece middle part is equipped with the universal driving shaft of shaft hole connection and moving contact linkage, the left and right sides of dysmorphism piece is equipped with the location cylinder, and the reference column body coupling corresponds with the cylinder of location cylinder on the elastic component, is equipped with a plurality of arc recesses on the periphery of dysmorphism piece and reference column physical contact, and under the spring action of elastic component, the cylinder of location cylinder gets into the arc recess and carries out circumferential location to special -shaped. The utility model discloses a location cylinder entering arc recess of being connected with the elastic component carries out circumferential location to the dysmorphism piece to make the moving contact obtain accurate location, ensure electrical safety.
Description
Technical field
This utility model relates to a kind of twin-power switch, is specifically related to the moving contact positioner of a kind of twin-power switch。
Background technology
The effect of twin-power switch is: when a road power failure (have a power failure, under-voltage, overvoltage, disconnected phase, frequency shift (FS)), twin-power switch action makes to automatically switch between standing power supply, to ensure reliability and the safety of power supply, it is widely used in the important place that skyscraper, community, hospital, airport, harbour, fire-fighting, metallurgy, chemical industry, weaving etc. do not allow to have a power failure, it is achieved unmanned is powered continuously。Cause the damage of power equipment to prevent standing power supply to be also turned on, at present, the moving contact of twin-power switch rotates and is driven by interlocking gear, but does not have special location structure, is easy for causing open circuit or short circuit when moving contact turned position is inaccurate。
Summary of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide one makes moving contact be accurately positioned, it is ensured that the twin-power switch moving contact positioner of Electrical Safety。
For this, this utility model adopts following scheme to realize:
The moving contact positioner of twin-power switch, including housing, it is characterized in that: in described housing, be provided with Special-shaped sheet, it is provided with axis hole in the middle part of described Special-shaped sheet to connect and the universal driving shaft of moving contact linkage, the left and right sides of described Special-shaped sheet is provided with location cylinder, location cylinder is connected on elastic component, corresponding with the cylinder of location cylinder, Special-shaped sheet and the periphery positioning cylinders contact are provided with some arc grooves, under the elastic force effect of elastic component, the cylinder of location cylinder enters arc groove and carries out circumferentially positioned to Special-shaped sheet。
After adopting technique scheme, enter arc groove by the location cylinder being connected with elastic component and Special-shaped sheet is carried out circumferentially positioned, so that moving contact is positioned accurately, it also is able to the moving contact position skew effectively preventing from producing due to the minor rotation of Special-shaped sheet, it is ensured that Electrical Safety simultaneously。
As preferably, described elastic component is upper lower spring, and the upper spring of upper end connection of location cylinder, the lower end of location cylinder connects lower spring, and upper lower spring bends setting along the circumference of Special-shaped sheet, and the upper end of upper spring and the lower end of lower spring connect on the housing。
Accompanying drawing explanation
This utility model has drawings described below:
Fig. 1 is structure principle chart of the present utility model。
Detailed description of the invention
As shown in Figure 1, the moving contact positioner of twin-power switch of the present utility model, including housing 1, it is provided with Special-shaped sheet 2 in described housing 1, it is provided with axis hole 8 in the middle part of described Special-shaped sheet 2 to connect and the universal driving shaft 3 of moving contact linkage, the left and right sides of described Special-shaped sheet 2 is provided with location cylinder 6, location cylinder 6 is connected on elastic component, corresponding with the cylinder of location cylinder 6, the periphery that Special-shaped sheet 2 contacts with location cylinder 6 is provided with some arc grooves 4, under the elastic force effect of elastic component, the cylinder of location cylinder 6 enters arc groove 4 and carries out circumferentially positioned to Special-shaped sheet 2。Described elastic component is upper lower spring, and the upper spring 5 of upper end connection of location cylinder 6, the lower end of location cylinder 6 connects lower spring 7, and upper lower spring bends setting along the circumference of Special-shaped sheet 2, and the upper end of upper spring 5 and the lower end of lower spring 7 are connected on described housing 1。
