Description
Technical field
This utility model relates to a kind of residual current circuit breaker, particularly to the operating mechanism of a kind of residual current circuit breaker.
Background technology
At present, publication number on market is the reclosing operation mechanism that the Chinese patent of CN204303724 discloses a kind of residual current action breaker, automatic reclosing gate assembly that it includes being arranged on breaker body and be movably arranged on panel manual knob, with reference to its accompanying drawing, one end of long connecting rod is connected on one end of short connecting rod, and the other end of long connecting rod is bolted on described supporter.
In such scheme, handle is sequentially connected with supporter, bolt, long connecting rod, the female trapezoidal axle sleeve of band and nut from top to bottom, before assembling, the threaded rod entirety of bolt is exposed to, partial threads bar is still had to be exposed to after assembling, so threaded rod is easily subject to ectocine and aoxidizes, and helicitic texture is easily subject to infringement, after the helicitic texture on threaded rod surface destroys, supporter entirety needs to reinstall, and operation is inconvenience extremely.
Utility model content
The purpose of this utility model is to provide the operating mechanism of the residual current circuit breaker of the screw connection structure firm and durable of a kind of supporter.
Above-mentioned technical purpose of the present utility model has the technical scheme that the operating mechanism of a kind of residual current circuit breaker, including the connecting rod that handle and the handle for divide-shut brake links, described handle is arranged with supporter, described supporter is provided with mean for the locating dowel of connecting rod socket, also includes preventing the banking stop that locating dowel deviate from by connecting rod, the screw being inserted in locating dowel.
Installation process is as follows; handle first puts supporter, is then inserted in connecting rod by locating dowel, after connecting rod is inserted in locating dowel; again banking stop is inserted in locating dowel; make connecting rod be between banking stop and locating dowel, finally screw in screw again to locating dowel, prevent deviating from of connecting rod by the barrier effect of banking stop; so far screw has been completely screwed in locating dowel; the inner threaded surface laminating of the external screw thread face of screw and locating dowel, it is to avoid flank exposes in atmosphere, and helicitic texture obtains protection.
This utility model is further arranged to: described locating dowel includes the overcoat with cylindrical cavity, is embedded in the inner sleeve of overcoat, inside puts and is provided with the chuck abutted with supporter inwall.
By technique scheme, the chuck of inner sleeve is similar to the shaft shoulder and is connected on supporter inwall, and adopts the modes such as welding to fix, and overcoat coordinates the thickness adding attachment structure and intensity with inner sleeve so that warping resistance ability when locating dowel is pulled by connecting rod is higher.
This utility model is further arranged to: described connecting rod is provided with the pars convoluta of stepped bending near supporter place.
Pass through technique scheme, the structure that pars convoluta has can promote supporter, and pars convoluta has shared the active force of interlinking lever end, uses connecting rod can pass through multiple spot driving handle, therefore the power that each position of connecting rod is shared is less so that connecting rod entirety antiflex cracking ability is improved.
This utility model is further arranged to: described locating dowel is provided with boss, described boss inwall circumference bevelling.
By technique scheme, not tapping in boss but inwall circumference bevelling, then screw easily slides into along boss inwall, facilitates screw location and installation.
This utility model is further arranged to: described supporter is inverted concave shape structure, and supporter is provided with several screwed holes coordinated with handle.
By technique scheme, handle inserts in supporter and takes bolt and screws in screwed hole, it is achieved supporter installation on handle, easy to operate is simultaneously achieved dismountable effect.
This utility model is further arranged to: described supporter includes two clamping plates, and screwed hole is run through handle to opposite side clamping plate by wherein side clamping plate.
Pass through technique scheme, the two clamping plates of supporter all obtains fixing on handle, and fixed form is to run through handle by whole for bolt, now move supporter needs the two ends to bolt to apply active force simultaneously, N number of bolt just has the point of 2N anti-shearing force, therefore the fixed effect realized is notable, it is to avoid supporter loosens.
In sum; this utility model have the advantages that installing connecting rods after realize be connected with each other place flank hide; so screw thread is in internal shielded state; avoid the destruction of helicitic texture; connecting rod multiple spot driving handle simultaneously; the less active force in multiple positions converges as bigger active force, and the process of connecting rod driving handle is more smooth and easy.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
nullEmbodiment one: such as Fig. 1，A kind of operating mechanism of residual current circuit breaker，Including the handle 1 for divide-shut brake、Connecting rod 2 with handle 1 linkage，Handle 1 is arranged with supporter 3，Supporter 3 is provided with mean for the locating dowel 4 of connecting rod 2 socket，Also include the banking stop 6 preventing connecting rod 2 from deviating from locating dowel 4、It is inserted into the screw 5 in locating dowel 4，Installation process is as follows，Handle 1 first puts supporter 3，Then it is inserted in connecting rod 2 by locating dowel 4，After connecting rod 2 is inserted in locating dowel 4，Again banking stop 6 is inserted in locating dowel 4，Connecting rod 2 is between banking stop 6 and locating dowel 4，Finally screw in again in screw 5 to locating dowel 4，Screw 5 can be set to one with banking stop 6，Convenient installation，Deviating from of connecting rod 2 is prevented by the barrier effect of banking stop 6，So far screw 5 has been completely screwed in locating dowel 4，The external screw thread face of screw 5 and the inner threaded surface laminating of locating dowel 4，Avoid flank to expose in atmosphere，Helicitic texture obtains protection.
