Abstract
A lead-screw connecting bar-type knife-edge commutation inversion insulator actuating device is composed of a shell and a hand knob connected with the shell. The hand knob and the shell employ a screwed joint. The hand knob is connected with a rotary rod shaft through a connecting bar. One end of the rotary bar is connected with a shell shaft, the other end of the rotary bar is connected with a drive link shaft, and the drive link is connected with a razor blade shaft of a knife-edge insulator. Due to the screwed joint between the hand knob and the shell, the hand knob rotates and moves in a straight line simultaneously when being rotated, the connecting bar is driven to move, which activates the rotary bar and the drive link to move and controls the razor blade of the knife-edge insulator. The hand knob and the shell employ a screwed joint, which can reach the self-hold request of the device. A slider-crank device composed of a hand knob, a connecting bar and a rotary bar is characterized in quick-return, thereby the device has functions of energy-storage and quick-return.
Description
Technical field
The utility model relates to a kind of knife-edge conversion isolator, particularly a kind of leading screw link-type knife-edge conversion isolator drive device.
Background technology
Knife-edge conversion isolator is mainly used in manual connection, cut-out or the buffer circuit in interchange and the DC distribution circuit.Existing knife-edge conversion isolator has central lever operating mechanism formula, center front rotary manipulation mechanism formula etc.The center front rotary manipulation mechanism formula knife-edge conversion isolator that uses at present adopts a gimbal structure, and self-locking performance is poor, connects when disconnecting, and does not have energy-storage function.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide a kind of and not only can connect, cut-out or buffer circuit, satisfied simultaneously the anxious function of returning of self-locking performance and energy storage again, and leading screw link-type knife-edge conversion isolator drive device simple in structure, with low cost.
For achieving the above object, the technical solution adopted in the utility model is: comprise housing and the handle that is connected with housing, handle adopts with housing and is threaded, handle is connected with the swingle axle by connecting rod, one end of swingle is connected with housing shaft, the other end of swingle is connected with the drive link axle, and drive link is connected with the blade shaft of knife-shaped isolator.
Because handle of the present utility model and shell adopt and be threaded, when turning handle, handle is done rotation and rectilinear motion simultaneously, the drive link motion, and with driven rotary bar and drive link, the blade of control knife-shaped isolator.Handle adopts with shell and is threaded, and can satisfy the self-locking requirement of mechanism.Handle, connecting rod, swingle are formed slider-crank mechanism, and quickreturn characteristics is arranged, so mechanism has the anxious function of returning of energy storage.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1, the utility model comprises housing 2 and the handle 1 that is connected with housing 2 by screw thread, handle 1 is connected with 3 of swingles by connecting rod 6, one end of swingle 3 is connected with 2 of housings, the other end of swingle 3 is connected with 4 of drive links, and drive link 4 is connected with 5 on the blade of knife-shaped isolator.
When turning handle 1, handle is done rotation and rectilinear motion simultaneously, drive link 6 motions, and with driven rotary bar 3 and drive link 4, the blade 5 of control knife-shaped isolator.Handle adopts with shell and is threaded, and can satisfy the self-locking requirement of mechanism.Handle 1, connecting rod 6, swingle 3 are formed slider-crank mechanism, and quickreturn characteristics is arranged, so mechanism has the anxious function of returning of energy storage.
