Utility model content
Problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of compact-sized, surface shape
Shape rule is round and smooth, and can satisfy breaker operator pull rod little space and the very high one kind of insulating requirements prevents high-voltage circuitbreaker from grasping
Make the connection structure that bar connecting pin falls off.
The technical solution adopted in the utility model includes the first operation pull rod, the second operation pull rod, resilient attachment pins and steel
Silk retaining ring, the sectional area of the elastic spring are circular configuration, are machined with installation elastic connection on the first operation pull rod
First connecting hole of pin is machined with the second connecting hole of installation resilient attachment pins, described the on the second operation pull rod
Elastic spring mounting groove and elastic spring insertion hole are machined on the excircle of one operation pull rod, in one end of the elastic spring
It is machined with elastic spring crotch, is machined with the gear of the semicircular steel wires for installing elastic spring at the both ends of the resilient attachment pins
Mounting groove is enclosed, the resilient attachment pins are inserted perpendicularly into the first connecting hole of the first operation pull rod and the second of the second operation pull rod connects
It connects in hole；Elastic spring, the steel are installed in the elastic spring mounting groove processed on the excircle of the first operation pull rod
The elastic spring crotch of silk retaining ring one end processing is inserted in the elastic spring insertion hole processed on the excircle of the first operation pull rod
In, and wind with one circuit along the outer surface of the first operation pull rod, so that elastic spring be fixed, and pass through semicircular steel wires retaining ring
Mounting groove limits resilient attachment pins.
The groove depth for the elastic spring mounting groove processed on the excircle of the first operation pull rod is 3mm~5mm.
Elastic spring insertion hole is perpendicular to the first connecting hole.
The internal diameter of the semicircular steel wires back-up ring mounting groove and the outer diameter of elastic spring match.
Compared with prior art, the structure of the utility model is conducive to limit resilient key taking off during breaker operator
From, and produce following the utility model has the advantages that limiting circuit breaker operates using the elastic spring that can be fixed on breaker operator pull rod
What pull rod connection resilient key was likely to occur in operation falls off, and one end of elastic spring is inserted on breaker operator pull rod
Perpendicular in the hole in pin direction, elastic spring winds with one circuit along the outer surface of moving component, effectively limits the position of resilient key
It sets, the sectional area of elastic spring is circular configuration, is provided at the position of breaker operator pull rod installation elastic spring and keeps off with steel wire
It encloses in the consistent semicircular steel wires back-up ring mounting groove of outer diameter, the reliable of breaker operator pull rod resilient key during exercise may be implemented
Limit, makes connecting pin be unlikely to fall off in breaker operator, to avoid the generation of accident.

Specific embodiment
Specific embodiment of the present utility model is provided with reference to the accompanying drawing.
As depicted in figs. 1 and 2, the technical solution adopted in the utility model includes that the first operation pull rod 1, second operates pull rod
4, resilient attachment pins 2 and elastic spring 3, the sectional area of the elastic spring 3 are circular configuration, in the first operation pull rod 1
On be machined with installation resilient attachment pins 2 the first connecting hole 1.3, it is described second operation pull rod 4 on be machined with installation elasticity even
Second connecting hole 4.1 of outbound 2, the resilient attachment pins 2 are inserted perpendicularly into the first connecting hole 1.3 and of the first operation pull rod 1
In second connecting hole 4.1 of two operation pull rods 4；
As shown in Fig. 3~Fig. 5, the steel that groove depth is 3mm~5mm is machined on the excircle of the first operation pull rod 1
Silk back-up ring mounting groove 1.1 and elastic spring are inserted into hole 1.2, side of the elastic spring insertion hole 1.2 perpendicular to resilient attachment pins 2
To being machined with elastic spring crotch 3.1 in one end of the elastic spring 3；At the both ends of the resilient attachment pins 2, processing is useful
In the semicircular steel wires back-up ring mounting groove 2.1 of installation elastic spring 3, the internal diameter and steel of the semicircular steel wires back-up ring mounting groove 2.1
The outer diameter of silk retaining ring 3 matches；
Elastic spring 3 is installed in the elastic spring mounting groove 1.1 processed on the excircle of the first operation pull rod 1,
The elastic spring crotch 3.1 of described 3 one end of elastic spring processing be inserted on the excircle of the first operation pull rod 1 process it is vertical
It winds with one circuit in the elastic spring insertion hole 1.2 in 2 direction of resilient attachment pins, and along the outer surface of the first operation pull rod 1, from
