Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", and the like, indicate positional or positional relationships, are merely for convenience in describing the present invention and to simplify the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Example one

Referring to fig. 1, the utility model relates to a leak-proof plastic shell connector for a refrigerator, which comprises a connector shell 1; the outer surface of the periphery of the connector shell 1 is fixedly connected with a flange 2, the flange 2 is completely attached to the outer surface of the connector shell 1, and the flange 2 and the connector shell 1 can be connected through hot melting or obtained through integral injection molding; the flange 2 can be round or rectangular; the outer surface of the connector shell 1 is connected with two clamping blocks 3; the two clamping blocks 3 are symmetrically arranged relative to the connector shell 1, so that the stress is balanced after clamping. The side surface of the flange 2 is connected with an annular sealing component 4 through gluing, and the sealing component 4 can be a double-sided foam adhesive tape.

As shown in fig. 2, the section of the fixture block 3 is wedge-shaped, and the inclined surface is located at one side close to the sealing component 4; the fixture block 3 is connected with the surface of the connector shell 1 through the two connecting strips 301 at one side far away from the sealing part 4, and a gap is reserved between the fixture block 3 and the surface of the connector shell 1, so that the fixture block 3 can move towards the direction close to the connector shell 1 when being extruded and can rebound under the elastic action of the connecting strips 301; limiting clamping grooves 302 are uniformly distributed on the inclined surface of the clamping block 3; the size of the opening of the limiting clamping groove 302 decreases towards the direction close to the sealing part 4.

The lower surface of the fixture block 3 is provided with a hem 303; hem 303 lower part supports with connector housing 1 surface and leans on, and hem 303 slightly inclines to set up, and when fixture block 3 atress pushed down, hem 303 produced and warp or crooked, increases fixture block 3's resilience force for fixture block 3 can kick-back rapidly and inside lining block, and simultaneously, great resilience force also can make the block between fixture block 3 and inside lining inseparabler, effectual improvement stability and reliability.

Preferably, the cross sectional shape of spacing draw-in groove 302 is right angled triangle, and right angled triangle's structure can make the horizontal right angle limit of spacing draw-in groove 302 and the laminating of connecting hole internal surface on the inside lining, and vertical right angle limit and the laminating of inside lining side to the spacing stability of block has been improved.

Meanwhile, the opening of the limiting clamping groove 302 is smaller and smaller towards the direction close to the sealing part 4, and during installation, one end of the connector shell 1, which is connected with the clamping block 3, is inserted into the connecting hole of the lining, so that the sealing part 4 adopting the double-sided foam adhesive tape is bonded with the side surface of the lining. When beginning to connect, the clearance is great between sealing member 4 and the inside lining, utilizes the opening great, and the great spacing draw-in groove 302 of the horizontal right angle side length of spacing draw-in groove 302 cross sectional shape promptly is spacing with the connecting hole block on the inside lining.

After the sealing part 4 is completely attached to the lining, the double-sided foam adhesive tape is deformed by extruding the flanges 2, and under the condition of small deformation, the opening of the limiting clamping groove 302 is small, namely the length of the horizontal right-angle side of the cross section shape of the limiting clamping groove 302 is small. Consequently, when the cotton sticky tape deflection of two-sided bubble is less, the distance that connector housing 1 drove 3 removals of fixture block is also less relatively, at this moment because the opening of spacing draw-in groove 302 is less, the moving distance of 3 relative inside lining sides of fixture block still can cross the width of a spacing draw-in groove 302, thereby make a spacing draw-in groove 302 more close to the inside lining side block the inside lining, thereby make the effect of block inseparabler, and make the cotton sticky tape of two-sided bubble and inside lining surface contact laminate more, improve sealed effect.

As shown in fig. 3, an annular strip 201 is fixedly connected to the connecting surface of the rib 2 and the sealing component 4; the annular strip 201 abuts against the inner surface of the sealing component 4, and the annular strip 201 can effectively improve the radial deformation resistance of the sealing component 4.

Arc-shaped protrusions 202 are uniformly distributed on the connection surface of the flange 2 and the sealing component 4, and the arc-shaped protrusions 202 can effectively improve the contact area of the flange 2 and the sealing component 4, so that the stability and the reliability of the sealing component 4 under the radial force are improved.

Example two:

on the basis of the first embodiment, the sealing component 4 is an elastic sealing gasket, the elastic sealing gasket is fixedly connected with the flange 2 through adhesion, the annular convex strips 203 are uniformly distributed on the connecting surface of the flange 2 and the sealing component 4, the annular convex strips 203 are concentrically arranged, and the annular convex strips 203 can also improve the fixing effect between the elastic sealing gasket and the flange 2 and the deformation resistance of the elastic sealing gasket.

The elastic sealing gasket can also be coated with non-setting adhesive to be adhered with the side surface of the lining, so that the sealing effect of the elastic sealing gasket is further improved. The rib 2 can also be connected with the elastic sealing gasket by means of an arc-shaped protrusion 202.

Utilize sealing member 4 on flange 2 to be sealed with the inside lining laminating, the effectual sealed quality that has improved compares the current mode that adopts to increase sheath and sticky tape and carry out the leaking stoppage, the utility model discloses an operation is more simple and convenient, the effectual sealed effect and the installation effectiveness that have improved, simultaneously, the effectual manufacturing cost that has practiced thrift.
