Abstract

Oven door sealing strips are commonly used for electric appliances such as ovens, microwave ovens and the like, generally consist of glass fiber outer sleeve parts and braided metal wire tube inner cores, and form closed loops through buckles; the sealing ring is connected with the door and the cavity of the electric appliance through a buckle. But the base of the buckle that adopts at present is mostly the monocycle, very easily takes place the displacement after the installation. The utility model aims at providing a furnace gate sealing strip. The hollow tubular component consists of an inner core of a braided metal wire tube and a braided glass fiber tube, and the second end of the hollow tubular component is sleeved into the first end and then fixed at the joint of the two ends by the buckles to form a closed-loop sealing ring; wherein the buckle includes buckle body and buckle base, and the buckle body passes through the neck with the buckle base and links to each other.

Description

Furnace door sealing strip

Technical Field

The utility model relates to a sealing washer, especially a furnace gate sealing strip that is used for roast chamber door, microwave oven door etc..

Background

Doors for ovens, microwave ovens and the like are typically fitted with a tubular gasket around the door for sealing or other purposes.

In order to solve the problems, the utility model provides a furnace door sealing strip, which comprises a hollow tubular component comprising a first end and a second end and a plurality of buckles longitudinally arranged along the hollow tubular component, wherein the hollow tubular component comprises a braided metal wire tube inner core and a braided glass fiber tube, the second end of the hollow tubular component is sleeved into the first end and then fixed at the joint of the two ends by the buckles to form a closed-loop sealing ring; the buckle is characterized by comprising a buckle body and a buckle base, wherein the buckle body is connected with the buckle base through a neck, the buckle body is in a diamond shape, the buckle base is in a shape like a Chinese character '8', and the buckle neck is parallel to the plane of the buckle base.

Preferably, the buckle is formed by folding a single metal wire and is integrally formed.

Preferably, the buckle is made of stainless steel wire.

Preferably, the tail part of the 8-shaped non-closed structure of the buckle base is tilted, and the tail part is sequentially screwed upwards according to the 8 shape from the tilted part of the tail part until the buckle base is connected with the neck part.

Preferably, the buckle body is a non-closed diamond and is a non-planar diamond; the buckle body is made of elastic stainless steel wires, can deform when external force is applied, and can rebound to the original shape after the external force is eliminated so as to be connected with a door and a cavity of an electric appliance.

Preferably, the buckle base can also be in a 6 shape or a 9 shape.

Preferably, the hollow tubular member is composed of a braided metal wire tube inner core, a braided glass fiber tube and a braided metal wire tube outer mesh in sequence from inside to outside.

Preferably, the inner core of the braided metal wire tube and the outer net of the braided metal wire tube are both formed by braiding single stainless steel wires, and have elasticity.

Preferably, the gasket may be bent in a circular, rectangular or other shape corresponding to the shape of the door and cavity of the appliance.

Preferably, the electric appliance may be an oven, an electric baking pan, a microwave oven, a light wave oven, or the like.

The utility model discloses positive effect that has:

(1) the base of the buckle used by the sealing ring provided by the utility model adopts the 8-shaped, 6-shaped or 9-shaped structure, and the displacement is not easy to occur after the base is installed;

(2) the utility model provides a sealing washer has added the one deck in addition again and has woven the wire pipe outer net in traditional sealing washer outside, can reach the protection and weave the purpose of glass fiber pipe, reaches the function that keeps the leakproofness lastingly.
