The utility model mainly is, location be not easy to transfer the files after complicated for existing tapping switch gear-shifting process, causes the problem such as handle corrosion easily, provide a kind of can be effectively to the joystick location, be convenient to transfer the files, need not the removal handle protective cover, avoid the non-excitation tapping switch structure of handle corrosion.
The purpose of this utility model mainly is achieved by following proposal: a kind of non-excitation tapping switch structure, comprise holder, joystick, be set in the handle in the joystick outside, described joystick is connected with dynamic contact mechanism away from an end of handle, described joystick and handle are flexibly connected, described holder is provided with location notch near an end of handle, and described handle is provided with the location plug-in unit that matches with location notch near an end of holder.Holder is fixed on the transformation case lid by sealing device and ring flange, and joystick runs through holder and is connected with dynamic contact mechanism, and joystick is arranged with handle away from the end outside of dynamic contact mechanism.Be provided with location notch at holder near an end end face of handle, be provided with the location plug-in unit at handle near an end of holder, the location plug-in unit matches with location notch.When the needs regulation stall, only need pulling handle and rotary handle, drive the joystick rotation in the time of rotatable handle, drive the dynamic contact mechanism that is flexibly connected with joystick in the time of the joystick rotation, and then can come dynamic contact mechanism is regulated by rotary handle.After dynamic contact mechanism was adjusted to required gear, release handle made in the location notch on the location plug-in unit insertion holder on the handle, and location notch can carry out the location plug-in unit spacing, and then carries out spacing to joystick.Matching with gear in the position of location notch, guarantees the positional precision of gear by location notch, and then guarantee to transfer the files precision.Simplify the process of transferring the files, not only be convenient to transfer the files, and need not the protective cover on the removal handle, avoid the joystick in the handle to be corroded.
As preferably, described location notch is regular polygon and evenly around the axle center of holder.Location notch is regular polygon, the corresponding corresponding gear in the limit of the location notch of regular polygon, the limit of the location notch by regular polygon is come the location plug-in unit on the handle is carried out spacing, not only can guarantee the precision that handle is regulated, and the handle after can preventing from locating slides.Location notch is evenly around the axle center of holder, and when guaranteeing the rotation of handle and joystick, the location plug-in unit on the handle can be positioned on the same axis with location notch, prevents location notch and location plug-in unit dislocation.
As preferably, be provided with the tooth bar that is meshed with gear on the gear that is fixedly installed on the described joystick, the dynamic contact mechanism.Be fixedly installed gear on the joystick, tooth bar is set on the dynamic contact mechanism, and driven gear rotation when joystick rotates is because the rack and pinion on the dynamic contact mechanism is meshed, when gear rotates, can be with carry-over bar to move, and then can realize the gear adjusting by the regulation moving contact mechanism.
As preferably, described joystick is provided with limiting section near an end of handle, is provided with back-moving spring between handle and limiting section.Joystick arranges limiting section near an end of handle, between handle and limiting section back-moving spring is set, when the pulling handle, and handle and limiting section compression reseting spring; After the position that regulates handle, release handle, back-moving spring can driving handle, makes handle reset, make the location plug-in unit on the handle to insert in the location notch.
As preferably, described holder is provided with clamp nut near an end of handle.Holder arranges clamp nut near an end of handle, is fixed cover by clamp nut, fixed cover is pressed abd fixed on transformer tank covers.
Therefore, non-excitation tapping switch structure of the present utility model possesses following advantage: 1, handle and joystick are flexibly connected, end end face at the close handle of holder is provided with location notch, the location plug-in unit that matches with location notch near an end setting of holder at handle, transfer the files by pulling and rotary handle, by location notch the location plug-in unit on the handle is positioned, simplify the process of transferring the files, be convenient to transfer the files, need not the protective cover on the frequent removal handle, avoid the joystick in the handle to be corroded, and can guarantee by the position that location notch is set gear and the precision of transferring the files; 2, be provided with the tooth bar that is meshed with gear on the gear that is fixedly installed on the joystick, the dynamic contact mechanism, driven gear rotation during the joystick rotation, the tooth bar that gear can drive on the dynamic contact mechanism moves, and then regulation stall; 3, joystick is provided with limiting section near an end of handle, is provided with back-moving spring between handle and limiting section, and after pulling and the rotary handle, back-moving spring can reset by driving handle, and the location plug-in unit of being convenient on the handle reinserts in the location notch.
