Embodiment

Now in conjunction with the accompanying drawings the utility model is further described:

As shown in the figure, the embodiment of a kind of industrial plug with paraphase mechanism of the utility model, include header body 2, sheath shell 1, ground wire conduction lock pin 5 and two phase line

conduction lock pins

31,32, also include whirligig 4, described ground wire conduction lock pin 5 is fixed on the header body 2, described two phase lines conduction lock pin, 31,32 symmetries are fixed on the whirligig 4, and whirligig 4 is socketed on the header body 2 and with header body 2 rotatable 180 degree location and cooperates formation paraphase mechanism.Connect instead if the phase sequence of plug takes place the user in use, in the time of need putting upside down phase sequence, only need to be fixed with the whirligig 4 Rotate 180 degree of two phase line

conduction lock pins

31,32, can finish the more work of positive phase sequence, thereby greatly improve user's operating efficiency.

In the present embodiment, on header body 2, be provided with whirligig installing hole 21, be provided with half slot 211 in the upper end surface of installing hole 21, the both ends of half slot 211 are provided with location notch 2111, described whirligig 4 includes base 41, loam cake 42, compression spring 43 and rotary shaft 44, described phase line

conduction lock pin

31,32 are fixed on the base 41, loam cake 42 and base 41 be divided into installing hole seat 21 on, following two ends are also fixing with screw 45, be provided with compression spring 43 between described rotary shaft 44 and the loam cake 42, rotary shaft 44 circumferentially links with base 41, the axial displacement cooperation (but is meant rotary shaft 44 relative base 41 axial displacements, and when rotary shaft 44 rotates, then also rotation thereupon of base 41), and this rotary shaft 44 is provided with hammerlock 442, this rotary shaft 44 has its hammerlock 442 and is positioned in latched position in the location notch 2111 and rotary shaft 44 axial displacements and makes lock wall 442 break away from location notchs 2111 and open the position along half slot 211 revolving of rotation, and described loam cake 42 also is provided with short slot 421 with convenient wiring to phase line conduction lock pin.By moving on the pushing rotary shaft 44, make hammerlock 442 break away from location notch 2111 and just can rotate rotary shaft 44, rotary shaft 44 drives base 41 and loam cake 42 rotations simultaneously, be fixed in the also rotation thereupon of two phase lines

conduction lock pin

31,32 on the base 41, (be 180 degree when being rotated in place when rotating 180 degree, because the control of half slot 211 is arranged), rotary shaft 44 comes loose, under the elastic force of compression spring 43, so the hammerlock of rotary shaft 44 falls within for 442 times a stable screens position is just arranged in the location notch 2111, at this moment promptly finish the paraphase of phase sequence.

In the present embodiment, rotary shaft 44 circumferentially links with base 41, axial displacement cooperates by following realization is set: on base 41, be provided with rectangular groove 411, the lower end 443 of rotary shaft 44 should be strip mutually and overlap insert in constitute described circumferential interlock in this rectangular groove 411, axial displacement cooperates.And has a stable position in order to guarantee to compress spring 43 displacements, on described rotary shaft 44, also be provided with spring shaft 441, described compression spring 43 is set on the spring shaft 441, and operate rotary shaft 44 for convenience, the bottom side of described rotary shaft 44 also is provided with flat recess 4431 with respect to the port position, during operation rotary shaft 44, only stretch into this flat recess 4431 and promptly upward promote to move on the rotary shaft 44 and rotate with a word helical cutter.Certainly, it is also a lot of with the mode that base 41 circumferentially links, axial displacement cooperates to reach rotary shaft 44, such as the form that adopts two guide pillars and slip hole, but obviously adopt the mode meeting of present embodiment more convenient, in addition, the mode that the operation rotating shaft makes it to move also has multiple, does not enumerate one by one at this.

In the illustrated embodiment, the lower surface of described whirligig installing hole 21 is provided with half slot 212, this half slot 212 is symmetrical with installing hole 21 upper end half slots 211 positions, corresponding being provided with in the rotatable lower end half slot 212 that is arranged on this installing hole 21 in protruding position, location 412 on the base 41, certainly the utility model also can not established such half slot, because base is fixedlyed connected with loam cake, when having a positioning of rotating, loam cake does the time spent, base does not need to establish such positioner in addition in principle, but such positioner is set in addition the stationarity of utilizing when operating is arranged.

In addition; it needs to be noted; illustrated embodiment only is described in detail for the protection to utility model better, and and non-limiting, any improvement of being made based on invention essence of the present utility model is all naturally within protection range of the present utility model.
