Abstract

The utility model relates to sealing can cover. The sealing can cover comprises an outer cover, an inner cover, a sealing ring, a spring, a live shaft, a knob and a sealing plug, wherein the sealing ring is sleeved on the outer side of the inner cover, the spring is arranged between the outer cover and the inner cover, the live shaft is connected with the outer cover and the inner cover, and the knob is arranged on the outer cover and is connected with the live shaft. The knob can turn by 90 degrees and can drive the inner cover to move vertically relative to the outer cover during the turning process, the sealing ring is dilatant and deformed caused by the extrusion of an outer cover slope while the inner cover moves upward relative to the outer cover, and the sealing ring seals a can opening by extruding with an inner wall of a can cover along the complete circle. The sealing can cover is easy to use, the inner cover cannot deflect, and the seal is reliable.

Description

Sealed tank cap

Technical field

The utility model relates to a kind of sealed tank cap, particularly relates to the seal cover cap in order to the sealed shell of tank oral area.

Background technology

The Seal Design of sealable tank is varied on the market, it has a kind of mode is that cover is divided into enclosing cover and inner cap, in covered a seal ring, covered outward a driving lever by couple axle pulling inner cap to top offset, in the seal ring that covers be subject to loam cake extruding outwards distortion and with inner tank wall crush seal tank mouth; This mode, driving lever has the component of a side direction when stirring, can cause inner cap to top offset the time crooked and the sealing not tight, and driving lever is when final locked position, the position of inner cap is not the extreme higher position in the whole process, that is to say that the position of inner cap is not on the optimal position of sealing.

Summary of the invention

The utility model is for above deficiency, by a kind of new structure, provides a kind of new easy to use, sealed tank cap that sealing effectiveness is good.The utility model sealed tank cap can seal a tank body that opening is smooth.

The technical scheme that the utility model adopts is: sealed tank cap, comprise enclosing cover, inner cap, seal ring, spring, turning cylinder, knob and sealing plug, seal ring is enclosed within the inner cap outside, spring is between enclosing cover and inner cap, turning cylinder connecting lid and inner cap, knob are arranged on the outer connection of rotating axle that covers; Knob can rotate 90 degree, knob can drive inner cap with respect to the enclosing cover upper and lower displacement in the process of rotating, inner cap is with respect to enclosing cover during to top offset, and seal ring is subject to the extruding on enclosing cover inclined-plane and dilatational strain, and with the all-round extruding of inner tank wall the sealable tank mouth.

The beneficial effects of the utility model: knob drives in the process of inner cap upper and lower displacement, inner cap is not subject to the impact of cross component all the time, so inner cap can be not crooked, and knob is when being in locked position, also on the extreme higher position of whole displacement process, it is the most desirable that sealing effectiveness can reach for inner cap.

Fig. 1 is the block diagram of a case study on implementation of the utility model sealed tank cap;

Fig. 2 is the exploded view of this case study on implementation;

Fig. 3 is that this case study on implementation places on the tank body, and knob is positioned at the figure of opening position;

Fig. 4 is that this case study on implementation places on the tank body, and knob is positioned at the figure of sealing state position.

The specific embodiment

To shown in Figure 4, the utility model sealed tank cap is applicable to seal a tank body that opening is smooth such as accompanying drawing 1.This sealed tank cap comprises: an enclosing cover 2, an inner cap 3, a seal ring 4 that is enclosed within the inner cap outside, spring 5 between enclosing cover and inner cap, the turning cylinder 6 of connecting lid and inner cap, and one can twist and drive inner cap with respect to knob 1 and a sealing plug 7 of enclosing cover upper and lower displacement.

Do the cue mark 2.1 of knob opening and the cue mark 2.5 of sealing state above the enclosing cover 2, and two boss 2.2 with the inclined-plane that can force knob to rise and descend, a fitfull through hole 2.3 that is consisted of by four arcs in the middle of it, cooperate with two keys 1.1 of knob 1, in order to limit the rotational angle of knob 1; One oblique angle 2.4 is arranged on the muscle of the bottom of enclosing cover 2, and its effect is can force seal ring 4 outwards to be out of shape when inner cap 3 rises.

There is a cylinder 3.1 with mesopore that supplies turning cylinder 6 to pass at the center of inner cap 3, and delineation position spring 5 circular orientation muscle 3.2; There is a circle groove 3.3 in the outside of inner cap 3 in order to fixed seal ring 4.

Seal ring 4 is the annulus that are made by flexible glue, its inboard buckles in the outside groove 3.3 of inner cap 3, and the lateral outer incline is when inner cap 3 relative enclosing covers 2 during to top offset, the outside of seal ring 4 can be subject to the extruding at oblique angle, enclosing cover 2 bottom 2.4 and outwards be out of shape, and then produces extruding with inner tank wall.

The effect of spring 5 is to allow enclosing cover 2 and inner cap 3 in tension all the time with respect to turning cylinder 6 and knob 1, and when knob 1 forwarded the open position to, inner cap 3 can be under the effect of spring 5 and to bottom offset.

On one end of turning cylinder 6 screw thread is arranged, the nut 1.2 of inlaying in its mesopore 3.1 that passes inner cap 3 and the knob 1 is connected.

Respectively there is a key 1.1 the rotating shaft both sides of knob 1, when penetrating the mesopore 2.3 of enclosing cover 2, can limit knob 1 and can only rotate 90 degree; Be inlaid with a nut 1.2 in the rotating shaft of knob 1, in order to be connected with turning cylinder 6;

The material of sealing plug 7 is flexible glue, is loaded on counterbore 3.4 places of inner cap 3 bottoms, in order to the gap between inner sealing lid 3 and the turning cylinder 6.

In the time will sealing a tank body with the utility model sealed tank cap, knob 1 to be turned to enclosing cover 2 opening marks 2.1 places first, this moment, knob 1 was below the boss 2.2 of enclosing cover 2, inner cap 3 under the effect of spring 5 to bottom offset, seal ring 4 is in free state, its external diameter can cover the tank mouth like a cork less than the tank body internal diameter.Then, knob 1 is turned to enclosing cover 2 sealing state marks 2.5 places, this moment knob 1 at the napex of the boss 2.2 of enclosing cover 2, inner cap 3 under the effect of knob 1 to top offset, seal ring 4 is subject to the extruding at oblique angle, enclosing cover 2 bottom 2.4 and outwards is out of shape, and produces extruding with inner tank wall and makes Jar opening sealer.

When wanting the opening encapsulation tank, only need knob 1 is rotated go back to enclosing cover 2 opening marks 2.1 places again, knob 1 arrives again below the boss 2.2 of enclosing cover 2, inner cap 3 under the effect of spring 5 to bottom offset, this moment, seal ring 4 was in again free state, its external diameter is less than the tank body internal diameter, like a cork the opening encapsulation tank.

In sum, just can drive the upper and lower displacement of inner cap 3 by twisting knob 1, make seal ring 4 be in free state or the state that suffers oppression, reach the purpose of sealing and opening encapsulation tank.The simplicity of design of the utility model sealed tank cap is effective, and inner cap 3 can be not crooked in the process of upper and lower displacement, and knob 1 turns to enclosing cover 2 sealing state marks 2.5 places, and inner cap 3 is in the extreme higher position of whole motion process, and sealing effectiveness is good.
