Abstract
The invention discloses a half shaft and fastening arm fastening mechanism for a switch operating mechanism. A half shaft is fastened to a rolling wheel at one free end of a fastening arm; the other free end of the fastening arm is provided with a pendular ratchet pawl; and the outer rim of the ratchet pawl is supported against the rolling wheel on the outer rim of a bent arm. The fastening arm of the mechanism is provided with the ratchet pawl, so the direct fastening form between the fastening arm and the half shaft is converted into the fastening form that the ratchet pawl is supported against the fastening arm and the half shaft, and the fastening between the half shaft and the rolling wheel of the fastening arm becomes sliding contact between two cambered surfaces. The half shaft and the rolling wheel of the mechanism are not collided when fastened; and the half shaft and fastening arm fastening mechanism has the advantages of small abrasion, high reliability and long service life.
Description
Technical field
The present invention relates to a kind of vacuum switch, particularly relate to a kind of semiaxis button arm clip connection device of switch operating mechanism.
Background technology
Breaker structure is divided into operating mechanism and switch main body two parts.Breaker open operation and feed motion are finished by operating mechanism.Recent decades, the developing history of circuit breaker shows that operating mechanism has great influence to the development of circuit breaker.The dynamic property of circuit breaker and the operating technology that is adopted have very big relation.Operating experience shows for many years, and the mechanical breakdown of operating mechanism accounts for the circuit breaker total failare up to 70.3%.The main deficiency of existing pull operation mechanism: pull operation mechanism semiaxis 1 ' and button arm 7 ' snapping form (as shown in Figure 1), for button arm 7 ' is directly swung snapping semiaxis 1 ', wearing and tearing easily or damage in semiaxis 1 and button arm 7 ' contact position, brings unreliable action to switch.
Summary of the invention
The object of the present invention is to provide a kind of semiaxis button arm clip connection device of switch operating mechanism of little, highly reliable, the long service life of wearing and tearing.
For achieving the above object, technical solution of the present invention is:
The present invention is a kind of semiaxis button arm clip connection device of switch operating mechanism, and it comprises button arm, semiaxis, and described semiaxis is interlockingly connected with button arm free end.Described button arm is the triangle body member, one jiao of the button arm is socketed on the rotatable fixed axis, a rotatable roller is installed at another angle, this roller can lean mutually with semiaxis, its third angle is installed the pallet that can swing, the outer end of pallet can lean mutually with the roller of connecting lever outer end, and the inner of connecting lever is socketed on the driving shaft.
The Na Yijiao that pallet is installed on the described button arm offers a short slot, symmetry offers axis hole on two sidewalls of short slot, described pallet is by being plugged on being nested with in this short slot that bearing pin on the short slot sidewall axis hole can swing, the outer end of pallet exceeds short slot, so that lean mutually with the roller of connecting lever outer end.
After adopting such scheme,, button arm and the direct snapping form of semiaxis are converted into pallet lean the snapping form of detaining arm and semiaxis, make semiaxis and detain arm roller snapping and become two cambered surfaces and slide and contact owing on the button arm of mechanism of the present invention pallet is housed.Do not clash into when the semiaxis of mechanism of the present invention, roller snapping, have the advantage that wearing and tearing are little, highly reliable, the life-span is long.
The present invention is further illustrated below in conjunction with accompanying drawing and instantiation.
Description of drawings
Fig. 1 is the stereogram of the semiaxis button arm clip connection device commonly used;
Fig. 2 is a stereogram of the present invention;
Fig. 3 is a structural representation of the present invention.
Embodiment
As Fig. 2, shown in Figure 3, the present invention is a kind of semiaxis button arm clip connection device of switch operating mechanism.It comprises semiaxis 1, roller 2, pallet 3, button arm 4.
Described button arm 4 is the triangle body member, and one jiao of button arm 4 is socketed on the rotatable fixed axis, and a rotatable roller 2 is installed at another angle, and this roller 2 can lean mutually with semiaxis 1, and its third angle is installed the pallet that can swing 3.The outer end of described pallet 3 can lean mutually with the roller 51 of connecting lever 5 outer ends, and the inner of connecting lever 5 is socketed on the driving shaft.
The installation form of pallet 3 is: freedom one end at button arm 4 is offered a short slot 41, symmetry is offered axis hole 42 on two sidewalls of short slot 41, described pallet 3 is by being plugged on rotatable being nested with in short slot 41 of bearing pin on the short slot 41 sidewall axis holes 42, the outer of pallet 3 exceeds short slot 41, so that lean mutually with the roller 51 of connecting lever 5 outers.
Of the present invention focusing on: a free end at the button arm is installed the pallet that can swing.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modification, all should still belong in the scope that patent of the present invention contains.
