A kind of fluid pressure type electro-magnetic circuit breaker sealed tube is disclosed in patent documentation CN202473796U, comprise body (being equivalent to the sealed tube in the application), pole shoe (being equivalent to the fixed core in the application), iron core and spring, the end of body is by being marked with hydraulic oil in pole shoe shutoff and body, the port of body extends to form bell mouth shape laterally, the sidewall of pole shoe draw in to center and riveted in the port of body.Fluid pressure type electro-magnetic circuit breaker sealed tube in above-mentioned patent documentation has changed the connected mode between body and pole shoe, and body can not be out of shape, and has ensured that iron core can flexible motion and make the iron core can be completely and pole shoe laminating therein, and qualification rate is high, is convenient to process.But in above-mentioned patent documentation, go back Shortcomings: between body and pole shoe, have the sealing of two places, a place is the sealing of riveted place; Another place be the horn-like port of described body and the inner face of described pole shoe offset form sealing, the effect of this hermetically-sealed construction is not ideal enough, in use still can there is oil leakage phenomenon in product.
Utility model content
The purpose of this utility model is to provide the sealed tube device of the better hydraulic electromagnetic breaker of a kind of sealing property.
The technical scheme that realizes the utility model object is:
A sealed tube device for hydraulic electromagnetic breaker, comprises sealed tube and is connected with in the fixed core of the mouth of pipe of the described sealed tube of sealing of the nose end of described sealed tube;
The mouth of pipe edge of the described sealed tube formation flange that stretches out, the periphery of described fixed core is provided with ringwise riveted boss; Described fixed core is fixed by described riveted boss and described sealed tube riveted;
The inner face of described fixed core is provided with annular protrusion;
After described fixed core and described sealed tube riveted are fixing, described annular protrusion and described flange offset, and described flange and the described annular protrusion position that offsets is extruded and is formed with the annular groove mating with described annular boss forms.
In technique scheme, the cross sectional shape of described annular protrusion is triangle.
In technique scheme, the cross sectional shape of described annular protrusion is semicircle.
In technique scheme, the cross sectional shape of described annular protrusion is rectangle.
In technique scheme, the cross sectional shape of described annular protrusion is trapezoidal.
In technique scheme, the center of the inner face of described fixed core forms cylindrical boss, and described positioning convex is around described cylindrical boss setting.
The utlity model has positive effect: in the sealed tube device of (1) hydraulic electromagnetic breaker of the present utility model, the inner face of described fixed core is provided with annular protrusion; After described fixed core and described sealed tube riveted are fixing, described annular protrusion and described flange offset, and described flange and described annular protrusion 22 position that offsets is extruded and is formed with the annular groove mating with described annular boss forms, and the described annular groove on described flange is to be formed by described annular protrusion extruding in riveted fixation procedure; In sealed tube device in the utility model, have the sealing of two places between described sealed tube and described fixed core, a place is the sealing of riveted place; Another place be described annular protrusion and described flange offset form sealing, due to when the riveted, described annular protrusion can push described flange and make described flange relevant position form an annular groove matching with described annular protrusion, so just can make flange and described annular protrusion closely offset, therefore the sealing effectiveness of sealed tube and fixed core is better.
Brief description of the drawings
Fig. 1 is the cutaway view that the sealed tube device of hydraulic electromagnetic breaker of the present utility model dissects along axis.
Reference numeral shown in figure is: 1-sealed tube; 11-flange; 12-annular groove; 2-fixed core; 21-riveted boss; 22-annular protrusion; 23-cylindrical boss.
Embodiment
The structure of the sealed tube device below in conjunction with Figure of description to hydraulic electromagnetic breaker of the present utility model is done to illustrate:
As shown in Figure 1, the sealed tube device of the hydraulic electromagnetic breaker in the present embodiment comprises sealed tube 1 and is connected with in the fixed core 2 of the mouth of pipe of the described sealed tube 1 of sealing of the nose end of described sealed tube 1; The mouth of pipe edge of described sealed tube 1 stretches out and forms flange 11, and the periphery of described fixed core 2 is provided with ringwise riveted boss 21; Described fixed core 2 is fixed with described sealed tube 1 riveted by described riveted boss 21; The inner face of described fixed core 2 is provided with annular protrusion 22; After described fixed core 2 is fixing with described sealed tube 1 riveted, described annular protrusion 22 offsets with described flange 11, and described flange 11 and described annular protrusion 22 position that offsets is extruded the annular groove 12 being formed with described annular protrusion 22 form fit, the described annular groove 12 on described flange 11 be in riveted fixation procedure by described annular protrusion 22 push form; In sealed tube device in the present embodiment, also have the sealing of two places between described sealed tube 1 and described fixed core 2, a place is the sealing of riveted place; Another place is that described annular protrusion 22 offsets and forms sealing with described flange 11, due to when the riveted, described annular protrusion 22 can push described flange 11 and make described flange 11 relevant positions form an annular groove 12 matching with described annular protrusion 22, so just can make described flange 11 closely offset with described annular protrusion 22, therefore described sealed tube 2 is better with the sealing effectiveness of described fixed core 2.
