Abstract
This invention relates to an automatic change-over switch, the driving part includes a motor fixed on the base and set between two executive breakers, an installing plate fixed on the base plate, two slide blocks driven by the shaft of the motor fixed on the incomplete gear on said mounting plate and set at both sides of the gear and slide along the guiding shaft, there are teeth clutched with the gear on the slide blocks and bayonets combining with the handles of the master and stand-by breakers, which combines the general motion of the incomplete gear with the rack driving of the gear very well to realize the separation and combination motion separately for the two executive breakers.
Description
Affiliated technical field
The invention belongs to a kind of electric switch, particularly relate to a kind of automatic change-over.
Background technology
For realize two carry out circuit breakers close the branch conversion, in present known automatic change-over transmission mechanism employing is the crank that is driven both sides by driving-disc, driving-disc rotates under the drive of motor, and the crank of both sides is made circular motion respectively separately and driven two execution circuit breaker handle on/off switch.The shortcoming of doing like this is when crank rotates, crank and switch knob position contacting are becoming always, make handle stressed very inhomogeneous, and because stressed unreasonable of the crank of the left and right sides its handle when the execution circuit breaker handle action that drives automatic change-over also causes automatic change-over to carry out the damage or the fracture of circuit breaker handle easily.And because rotational angle is big, so intrinsic change-over time is long.
Summary of the invention
The present invention provides the circular motion of motor shaft to be converted into the automatic change-over that both sides execution circuit breaker handle is made the linearly operating transmission mechanism a kind of having for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: it includes base, carry out circuit breaker and transmission mechanism for active and standby two, described active and standby two execution circuit breakers and transmission mechanism are fixed on the described base, and described transmission mechanism includes the motors that are fixed on the base and place two execution circuit breaker centres, be fixed on the mounting panel on the base, two slide blocks that drive and be fixed on the partial gear on the described mounting panel and place described partial gear both sides and slide along the guide shaft that is fixed on the described mounting panel by the axle of described motor; On described slide block, have can with the tooth of partial gear engagement, and the bayonet socket that can combine with active and standby two handles of carrying out circuit breakers is arranged.
The present invention can also adopt following technical measures:
Described partial gear be only plane, gear place the 3rd, mid portions on the 90 degree circumference that comprised separately of four-quadrant have tooth, and all anodontia gear on the circumference in first, second quadrant on part beyond this and plane, gear place;
Described partial gear be plane, gear place the 3rd, from about Y, respectively change 37.5 ° and located three teeth on the circumference of 90 degree that comprised separately of four-quadrant.
On the described slide block can be perforation with the tooth of partial gear engagement;
Described slide block be about two slide blocks, and open the perforation of three positions, the engagement that can cooperatively interact with the tooth of described partial gear of the same size about described on two slide blocks.
Advantage and good effect that the present invention has are: this sets of transmission mechanism well combines the intermittent movement and the rack-and-pinion transmission that are realized by partial gear.Realized that two branches that close respectively of carrying out circuit breaker move.Broken through original thinking.Two difficult problems that the execution circuit breaker moves simultaneously in the rack-and-pinion transmission have been solved.Simultaneously the rack-and-pinion transmission is applied in the automatic change-over, also mentioned the reliability and the stationarity of action greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, at base 7 upper mounting plates execution circuit breaker 1,6 is installed below 8, on base 7, fixedly mounted mounting panel 8 and with upper mounting plate motor 4 has been installed below 8, on mounting panel 8, be installed with partial gear 3 and four guide shafts 9 at base 7 by four pillars.The axle of motor 4 is coaxial with the axle of partial gear 3.Partial gear 3 be one only halogen wheel plane, place the 3rd, from about Y, respectively change 37.5 ° on the circumference of 90 degree that comprised separately of four-quadrant and located three teeth, and all anodontia gear on the circumference in first, second quadrant on part beyond this and plane, gear place.And about respectively open with respect to partial gear 3 one sides on two slide blocks 2,5 three difference can with partial gear 3 the plane the 3rd, three tooth engagements and position, perforation of the same size in the four-quadrant.About be separately installed with left and right sides slide block 2,5 on each two guide shaft 9.On left and right sides slide block 2,5, be useful on card and contain the main bayonet socket 10 of carrying out the handle of circuit breaker 1 and carrying out the handle of circuit breaker 6 fully.
