Embodiment
Below in conjunction with accompanying drawing, with embodiment, the invention will be further described.
As shown in Figure 1, the embodiment of the present invention comprises and coordinating simultaneously as other structure units installation pedestal with rotation selection tool 3 for the rotation selection tool 2 with the plastics shell 1 of equipment connection, for switch selection, is positioned at plastics shell 1 center and runs through the rotation main shaft 3 of plastics shell 1.
As shown in Figure 2 and Figure 3, the rotation main shaft 3 of the embodiment of the present invention comprises the panel part 301 of exposing plastics shell 1 and rotates Plug Division 302, the transition rotating part 303 being arranged on the 302 times ends in Plug Division that selection tool 2 docks, fixes other structural parts, be arranged on transition rotating part 303 times ends square pin portion 304 and with the threaded portion 305 being arranged on the 304 times ends in square pin portion; Panel part 301 is offered and the insertion opening 3011 that rotation selection tool 2 coordinates, square pin portion 304 is socketed with the synchronous axial system when rotating main shaft 3 and rotate and selects to turn plate 7 with the plastics that this selects to make switch; Threaded portion 305 is socketed with the Plastic cap 5 coordinated with it, the outer cover of Plastic cap 5 is connected to pullback spring 6, the outside button of pullback spring 6 is connected to selects plate 7 to match with plastics, can be pulled the plastic switch sheet 8 that spring 6 retracts after being selected plate 7 to eject by plastics.
As shown in Figure 6, the rotation of the embodiment of the present invention selects duty to be made the shape of key, and it has the lobe 201 matched with spring piece, and person easy to use carries and uses, also spring structure that is convenient and rotation main shaft inside matches, and makes relatively good machinery encryption.
As shown in Figures 1 and 2, the embodiment of the present invention is inner in Plug Division 302, what arrange with being perpendicular to rotation selection tool 2 direction of insertion has to three leaf spring sheets 3021, a part for spring piece 3021 exposes Plug Division 302 outside surface when rotating selection tool 2 and do not insert and rotate main shaft 3, and Plug Division 302 outside surface is provided with the spring piece opening 3022 coordinated with spring piece 3021. It is provided with six in plastics shell 1 and exposes what Plug Division 302 outer surface part matched with spring piece 3021, the stuck groove 101 of stuck rotation main shaft when rotating selection tool 2 and do not insert rotation main shaft 3.
As shown in Figure 2, plastics select plate 7 to be one block of vertical arc trapezoidal plastic plate, and plastics select the trapezoidal top of plate 7 to be provided with two for ejecting the semicircle projection 701 of plastic switch sheet 7. Plastic switch sheet 8 be two panels independence and the hollow semicylinder of symmetry, the inclined-plane 801 that the outside surface of plastic switch sheet 8 is provided with semicircle projection 701 matches. The side of plastic switch sheet 8 is provided with and ensures the linear track projection 802 of its direction of action, it is provided with bottom track projection 802 and limits maximum retracted position to plastic switch sheet 8, simultaneously as the stop contact block 803 of switch contact, stop that the bottommost of contact block 803 exceeds the bottommost of plastic switch sheet 8. The outside side near plastic switch sheet 8 end of plastics shell 1 is provided with the rail groove 102 matched with track projection 802. On plastic switch sheet 8, with the bayonet socket 804 stopping that the top of end opposite end, contact block 803 place is provided with pullback spring 6 button connects.
As shown in figures 2 and 5, the embodiment of the present invention is also socketed with in square pin portion 304 to coordinate with plastics shell 1 and rotates, for limiting, the corner restriction pad 9 that main shaft 3 rotates angle, corner restriction pad is arranged on plastics and selects between plate 7 and plastics shell 1, and corner restriction pad 9 is provided with corner restriction contact 901. Plastics shell 1 is inner, it is provided with the rotating hole 103 coordinated with transition rotating part 303, being provided with the corner limiting groove 104 limiting pad 9 match with corner around rotating hole 103, the limited angular of corner limiting groove is generally 70 �� ~ 90 �� and can adjust according to the user demand of reality.
The embodiment of the present invention is inserted into rotate selection tool 2 in rotation main shaft 3 in use, will taking in completely in spring piece opening 3022 of the spring piece 3021 now matched with rotation selection tool 2, stuck like this groove 101 just loses stuck function, rotates main shaft 3 and just can rotate. Select plate 7 and then to rotate semicircle projection 701 when main shaft 3 rotates when plastics and will withstand the inclined-plane 801 of the plastic switch sheet 8 by turning direction side, when being rotated further, semicircle projection 701 will eject plastic switch sheet 8 along the vergence direction on inclined-plane 801, completes selection action with this. And stop that the switch contact of external equipment corresponding position will be touched in the bottom of contact block 803, get through the circuit on this road, this completes selection action. And when not rotating selection tool 2, the present invention outside does not have can for the parts rotated, so mishandle would not be caused, when using not corresponding rotation selection tool 2, also cannot match with the spring piece 3021 rotated in main shaft 3, therefore main shaft 3 cannot be rotated, avoid the possibility of artificial destruction.
More than illustrate it is only explanation of the invention, those of ordinary skill in the art's can completely is made to implement this scheme, but it is not limitation of the present invention, the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification sheets, and these are all not creative amendments.But as long as being all subject to the protection of patent law in the right of the present invention.
