Abstract

The invention discloses a kind of gasket of button, include the body of tabular, the edge of body is provided with the first flange, and body is located at the side of the first flange, and to be provided with first raised and abutted around first the first raised groove, the first raised top with button.A kind of gasket of button of the present invention, deformation drag is small, user-friendly button.

Description

A kind of gasket of button

Technical field

The present invention relates to the sealing structure of button, more particularly to a kind of gasket of button.

Background technology

In the prior art, the household electrical appliance such as bread producing machine, rice mill are both provided with the convenient button operated and are controlled.To protect Card sealing, can set a gasket, gasket is generally plain cushion, is set around gasket between button and bread producing machine or rice mill A circle flange is equipped with, flange is used to position.When carrying out function switch by lower button, button can promote gasket to move, sealing Contacted after pad deformation with the control system inside bread producing machine or rice mill, the functions such as realization starts, suspends, stopping.

However, since gasket performance itself has differences, make gasket deformation power used of different sizes, extreme case The less user that puts forth strength cannot press button.

The content of the invention

Present invention seek to address that above-mentioned mentioned technical problem, there is provided a kind of gasket of button, deformation drag is small, User-friendly button.

The present invention is realized by following technical solution：

A kind of gasket of button, includes the body of tabular, and the edge of body is provided with the first flange, and body is positioned at the The side of one flange is provided with the first first groove raised and around the first protrusion, and the first raised top is abutted with button.

Preferably, the first raised length direction along body extends, the first raised and length side of first groove along body Set to biasing.

Further, body is provided with the second groove backwards to the first raised side, and the second groove makes the first raised thickness Degree is equal in the thickness of the first groove with body.

Further, the first flange is provided with the first opening of the first groove of connection.

Preferably, the extending direction of the first flange and the end face of body are vertical.

Further, the inner surface of the first flange and the angle of body end face are less than 90 °, inner surface and the sheet of the first flange The angle in body end face is more than 85 °.

Further, the first chamfering is provided with the top of the first flange, the first chamfering is arranged at the inner side of the first flange.

Beneficial effect is：Compared with prior art, a kind of gasket of button of the invention is by setting the first protrusion With the first groove so that the first groove deforms when button promotes the first raised movement, due to the thickness ratio of the first groove The thickness of body is small, and the deformation force occurred needed for moderate finite deformation is small, thus, user is small by the resistance that lower button needs overcome, side Just user's operation button.

Brief description of the drawings

The embodiment of the present invention is described in further detail below in conjunction with attached drawing, wherein：

Fig. 1 is a kind of structure diagram of the gasket of button of the present invention.

Embodiment

As shown in Figure 1, a kind of gasket of button, includes the body 1 of tabular, the edge of body 1 is provided with first and turns over Side 2.

First flange 2 is fastened on the inner side of bread producing machine or rice mill, prevents water from entering bread producing machine or rice mill by button Inside.

The deformation drag of gasket when pressing button to reduce, body 1 is located at the side of the first flange 2, and to be provided with first convex 3 and the first groove 4 around the first protrusion 3 are played, the top of the first protrusion 3 is abutted with button.

The first groove 4 deforms when first protrusion 3 that button promotes moves, due to the thickness ratio body 1 at the first groove 4 Thickness it is small, occur moderate finite deformation needed for deformation force it is small, thus, when the user depresses the button, it is only necessary to overcome the resistance of very little Power, very convenient user's operation.

First protrusion 3 is suitable for the button that can be upspring after pressing, that is, button meeting return after pressing, it is impossible to which holding is pressed Distance.

For ease of general, it is preferred that the first protrusion 3 extends along the length direction of body 1, the first protrusion 3 and the first groove 4 Bias and set along the length direction of body 1.

In this way, the first groove 4 is suitable for the button that will not upspring after pressing, that is, after pressing button can with bread producing machine or Rice mill keeps difference in height, and the deflection that the first groove 4 can be such that gasket keeps for a long time is reduced.

Shunk to reduce product, body 1 can be provided with the second groove backwards to the side of the first protrusion 3, and the second groove makes Thickness of the thickness of first protrusion 3 with body 1 at the first groove 4 is equal, the contour shape of the second groove and the first raised 3 classes Seemingly, no longer draw.

Anti-loaded to prevent, further, the first flange 2 can be provided with the first opening 21 of the first groove 4 of connection.

First opening 21 is used to position, easy to assemble.

To reduce amount of parts, the extending direction of the first flange 2 is vertical with the end face of body 1.

This make it that gasket is not easily to fall off, is fixed without auxiliary component, convenient follow-up assembling.

To make gasket be fitted closely with bread producing machine, further, the inner surface of the first flange 2 and the folder of 1 end face of body Angle is less than 90 °, and the inner surface of the first flange 2 is more than 85 ° with the angle of 1 end face of body.

In theory, this belongs to the back-off structure in injection, but since gasket has elasticity, influence is had no on production.

Due to the presence of back-off structure, the assembling of gasket and bread producing machine may become some difficulties, further, first The top of flange 2 is provided with the first chamfering 22, and the first chamfering 22 is arranged at the inner side of the first flange 2.

Guiding when first chamfering 22 is used to assemble.

The above embodiments are merely illustrative of the technical solutions of the present invention and is not limited, all without departing from the present invention Any modification of spirit and scope or equivalent substitution, it should all cover in the range of technical solution of the present invention.
