The hand one-way operating mechanism is characterized in that a one-way transmission mechanism comprises a base, a pawl and a pawl seat, wherein the base is connected with a hand operating mechanism, the base is provided with ratchets distributed uniformly circumferentially, the pawl is arranged on the pawl seat and is in ratchet transmission fit with the ratchets, and a transmission wheel is arranged inside the pawl seat and fixedly connected with the pawl seat. The hand one-way operating mechanism of a vacuum load switch has the advantages of compact structure and long service life.
Description
Technical field
The utility model relates to a kind of operating mechanism of vacuum circuit-breaker, specifically is meant the manual one-way operation of vacuum load switch mechanism.
Background technology
Present existing FZN21, FZN25 vacuum load switch all adopt similar closing by hand parts, its transmission mechanism all adopts unidirectional transmission, all be to adopt ratchet and click-fit to realize both drive connections, and ratchet is to adopt the pressure of inside and outside spring could to cooperate complex structure with ratchet, if spring pressure is too small, then occur skidding easily, if the poor reliability of combined floodgate is the pressure of outer spring in strengthening, easily make the ratchet wearing and tearing again, cause the reduction in useful life.
Summary of the invention
In order to overcome disadvantages of background technology, the utility model provides a kind of drawer plug-in type assembly unit residual current circuit breaker, and this dress residual current circuit breaker has advantage easy to connect, simple to operate, has solved the shortcoming that existing residual current circuit breaker connects inconvenience, operating difficulties.
The technical solution of the utility model is: the manual one-way operation of a kind of vacuum load switch mechanism, comprise the manual operation handle, drive, be provided with one-way driving mechanism between described manual operation handle and the drive, the manual operation handle drives drive by one-way driving mechanism, it is characterized in that: described one-way driving mechanism comprises pedestal, ratchet, pawl base, described pedestal is connected with manual-operating mechanism, pedestal is provided with the equally distributed interior ratchet of circumference, described ratchet is located on the pawl base and is formed the ratchet transmission with ratchet and cooperates, and described drive is positioned at pawl base inside and fixedlys connected with pawl base.
Further, described pawl base one end is provided with and ratchet is installed and with the manhole of opening, described ratchet is located in this through hole, and can be around the through hole circle swing.
Further, described drive is provided with the spring that is connected with ratchet.
Further, described ratchet is three and is evenly distributed.
The utlity model has following beneficial effect: because this unidirectional manual transmission is sealed in the parts of all control joystick transmissions in the pedestal, make the space of global shape of transmission mechanism dwindle greatly, but can remain its original characteristic and function, and compact conformation, this structure skidding can not occur in transmission process, the transmission efficiency height, and service behaviour is strong, and can bear bigger moment of torsion, prolong useful life greatly.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model.
Fig. 2 is the left view of Fig. 1 in the utility model.
Among the figure, manual operation handle 1, pedestal 2, pawl base 3, screw 4, ratchet 5, drive 6, spring 7, ratchet 8, through hole 9.
Embodiment
At accompanying drawing embodiment of the present utility model is described further below:
By Fig. 1, shown in Figure 2, the manual one-way operation of this vacuum load switch mechanism, comprise manual operation handle 1, drive 6, be provided with one-way driving mechanism between described manual operation handle 1 and the drive 6, described manual operation handle 1 drives drive 6 by one-way driving mechanism, described one-way driving mechanism comprises pedestal 2, ratchet 5, pawl base 3, described pedestal 2 is connected with manual-operating mechanism 1, pedestal 2 is provided with the equally distributed interior ratchet 8 of circumference, described ratchet 5 is located on the pawl base 3 and is formed the ratchet transmission with ratchet 8 and cooperates, and described drive 6 is positioned at pawl base 3 inside and fixedlys connected with pawl base 3.According to such scheme, because this unidirectional manual transmission is sealed in the parts of all joystick transmissions in the pedestal 2, make the space of global shape of transmission mechanism dwindle greatly, but can remain its original characteristic and function, and compact conformation, this structure skidding can not occur in transmission process, the transmission efficiency height, service behaviour is strong, and can bear bigger moment of torsion, and prolong useful life greatly.
In the utility model, by Fig. 1, shown in Figure 2, described pawl base one end is provided with installs ratchet 5 and with the manhole 9 of opening, described ratchet 5 is located in this through hole 9, and can be around through hole 9 circle swings.Pawl base 3 is provided with through hole 9 and is convenient to install ratchet 5, and ratchet 5 to be installed on through hole 9 internal stabilities good, the transmission effect is remarkable when cooperating with ratchet 8.
In the utility model, by Fig. 1, shown in Figure 2, described drive 6 is provided with the spring 7 that is connected with ratchet 8.Adopt spring 7 to cooperate and make that the agile property of ratchet 5 is better, and play the effect of location ratchet 5, prevent that ratchet 5 from dropping out in through hole 9 with ratchet 5.
In the utility model, by Fig. 1, shown in Figure 2, described ratchet 5 is three and is evenly distributed.Three ratchets 5 are set can make pedestal rotate and give the effect of pawl base 3 better transmission of power.
In the utility model, by Fig. 1, shown in Figure 2, described ratchet be 60 ° of angles.Adopt the ratchet at 60 ° of angles, select the ratchet that matches with ratchet for use, both can realize the transmission effect after cooperating preferably.Described ratchet is nine and is evenly distributed on the pedestal.Because ratchet is set to three, need be set to three multiple and could make three ratchets work simultaneously, consider on whole agile property and the effect in order to make, be set to nine the most suitable.
In the utility model, by Fig. 1, shown in Figure 2, manual operation handle 1 is connected by screw 4 with pedestal 2, manual operation handle 1 rotates and just drives pedestal 2 rotations, be arranged on after spring 7 is compressed in the hole of drive 6 and and be connected with ratchet 5, because ratchet 5 one ends and pedestal 2 unidirectional delivery moments of torsion, and the other end withstands on the through hole of pawl base 3, pedestal 2 rotates and drives ratchet 5 rotations, ratchet 5 drives pawl base 3 and rotates, and pawl base 3 adopts interference fit with drive 6, and drive 6 is connected with actuator again, when pedestal 2 clockwise directions rotate, ratchet 8 and ratchet 5 clamping mutually, thus drive 5 rotations of ratchet, realize closing a floodgate or separating brake, when pedestal counterclockwise rotates, ratchet 8 and ratchet 5 be transfer torque not, and but pedestal 2 rotates ratchet 5 transfixions, and ratchet 5 skids off in ratchet 8, this moment, spring 8 was compressed generation elastic force, just headed into when rotating next ratchet 8.Certainly, also can be set to counterclockwise pedestal and rotate the unidirectional delivery moment of torsion, clockwise transfer torque not.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
