Abstract

The utility model relates to a multifunctional expanding rubber ring, particularly a rubber ring used on the connector of the water inlet pipe of an automatic washing machine. The two ends of an inner hole are respectively provided with a chamfering of 45 DEG so that the rubber ring has both a sealing function and a connecting function. The connector of the water inlet pipe adopting the rubber ring of the structure can be conveniently assembled and disassembled. The utility model has a property of unease of water leakage, simple structure and low cost.

Description

Multifunctional expanding rubber ring

The utility model relates to a kind of cushion rubber, especially the cushion rubber that uses on the automatic washing machine water inlet pipe connector.

At present the cushion rubber that uses on the washing machine inflow tube connector is cylindrical, generally only seals, and promptly prevent to leak, and rubber washer also has other characteristics, as good springiness, on characteristics such as frictional force is big but are not fully utilized.

The purpose of this utility model is the cushion rubber that a kind of interior pore area chamfering will be provided, and it makes cushion rubber not only have sealing function but also have linkage function.

The purpose of this utility model is achieved in that at the two ends of cushion rubber endoporus falls a 45 respectively, and this cushion rubber wall thickness is slightly thin than conventional apron, and width is slightly wide than conventional apron.

The utility model is owing to adopted chamfering structure, do the time spent when what the cushion rubber two ends were under pressure, cushion rubber deformation pattern such as Fig. 3, and conventional apron deformation pattern such as Fig. 4, obviously, if water pipe (or water supply hose) is placed the cushion rubber endoporus, when the cushion rubber two ends of band chamfering are under pressure, cushion rubber inwardly expands, extruding water pipe or water supply hose, because rubber friction power is bigger, cushion rubber can play the connection effect, like this, adopt water inlet pipe connector easy accessibility, the antileaking, simple in structure and with low cost of the cushion rubber of band chamfering.

Fig. 1 is the cutaway view according to the multifunctional expanded cushion rubber that the utility model proposes.

Fig. 2 is the vertical view of multifunctional expanded cushion rubber.

Deformation pattern when Fig. 3 is multifunctional expanded cushion rubber two ends pressurized.

Deformation pattern when Fig. 4 is conventional apron two ends pressurized.

Describe structure of the present utility model in detail below in conjunction with accompanying drawing

With the water inlet pipe connector in the family expenses automatic washing machine is example,

The internal diameter of multifunctional expanded cushion rubber: φ 18mm---the cushion rubber that contacts with hose

φ 20mm---the cushion rubber that contacts with water supply hose

The wall thickness of cushion rubber: 3～4mm

The width of cushion rubber: 10mm---the cushion rubber that contacts with hose

12mm---the cushion rubber that contacts with water supply hose

Chamfering: 2 * 45 °

Claims

1, a kind of multifunctional expanded cushion rubber is characterized in that: respectively there is a chamfering at cushion rubber endoporus two ends.

2, multifunctional expanded cushion rubber as claimed in claim 1 is characterized in that; The chamfering at cushion rubber endoporus two ends is 45 °.
