Description
Technical field:
The present invention relates to two-direction switch technical field, be specifically related to a kind of two-direction switch with locking device.
Background technology:
Two-direction switch is also change over switch.Its effect is connection, deenergization or load, can make motor forward or reverse, is mainly to do the electric component that rotating is used to three-phase low-power machine, but can not serves as Automation Elements.
The principle of two-direction switch is: three phase mains provides a rotating magnetic field, three phase electric machine is rotated, and because of the connection difference of power supply three-phase, magnetic field can clockwise or be rotated counterclockwise, for a change turn to, only any two-phase phase sequence of motor power need to be changed and can complete.If original phase sequence is A, B, C, only need change into A, C, B or C, B, A.General two-direction switch has six terminals of two rows, and phase modulation, by middle contact commutation contact, reaches commutation object.Taking three phase electric machine two-direction switch as example: establish inlet wire A.B.C three-phase, outlet is also A-B-C, because ABC three-phase is each 120 degree of being separated by, connect into a circumference, the ABC establishing on this circumference is clockwise, is connected to after motor, motor is for turning clockwise.As B.C switched in switch, A is motionless as before, makes the outlet of switch become A-C-B, and the ABC on this circumference arranges and just become counterclockwise, is connected to after motor, and motor is also for being rotated counterclockwise. and this diverter switch is exactly two-direction switch.
Summary of the invention:
The object of this invention is to provide a kind of two-direction switch with locking device, it can prevent other people misoperation, ensures the fail safe of production, easy and simple to handle, easy to use.
In order to solve the existing problem of background technology, the present invention adopts following technical scheme: it comprises shell 1, contact mechanism 2, rotating shaft 3, rotating handles 4, it also comprises lock tube 5, lock shaft 6, spring 7, interlocking shell 8, the inside of shell 1 is provided with contact mechanism 2, rotating shaft 3 is installed in contact mechanism 2, one end of rotating shaft 3 is connected with rotating handles 4, lock tube 5 switches through on axle 3, the upper end of lock tube 5 is provided with lock shaft 6, interlocking shell 8 is arranged on shell 1, and offer locked groove 8-1 with lock shaft 6 corresponding sections on interlocking shell 8, spring 7 is socketed in rotating shaft 3, and one end of spring 7 is connected with lock tube 5, and the other end is connected with rotating handles 4.
Operation principle of the present invention is: first three-phase power line is connected, when use, need first with hand, lock tube 5 to be pulled back and then rotate rotating handles 4, after having started, lock tube 5 relies on the elastic force of spring 7 to reset forward, its lock shaft 6 can enter in corresponding locked groove 8-1, other people misoperation can be prevented, the fail safe of producing can be ensured.
The present invention has following beneficial effect: can prevent other people misoperation, ensure the fail safe of production, and easy and simple to handle, easy to use.
Brief description of the drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of housing 1 of the present invention.
Embodiment:
Referring to Fig. 1-Fig. 2, this embodiment adopts following technical scheme: it comprises shell 1, contact mechanism 2, rotating shaft 3, rotating handles 4, it also comprises lock tube 5, lock shaft 6, spring 7, interlocking shell 8, the inside of shell 1 is provided with contact mechanism 2, rotating shaft 3 is installed in contact mechanism 2, one end of rotating shaft 3 is connected with rotating handles 4, lock tube 5 switches through on axle 3, the upper end of lock tube 5 is provided with lock shaft 6, interlocking shell 8 is arranged on shell 1, and offer locked groove 8-1 with lock shaft 6 corresponding sections on interlocking shell 8, spring 7 is socketed in rotating shaft 3, and one end of spring 7 is connected with lock tube 5, and the other end is connected with rotating handles 4.
The operation principle of this embodiment is: first three-phase power line is connected, when use, need first with hand, lock tube 5 to be pulled back and then rotate rotating handles 4, after having started, lock tube 5 relies on the elastic force of spring 7 to reset forward, its lock shaft 6 can enter in corresponding locked groove 8-1, other people misoperation can be prevented, the fail safe of producing can be ensured.
This embodiment has following beneficial effect: can prevent other people misoperation, ensure the fail safe of production, and easy and simple to handle, easy to use.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
