Description

Seals

The new model relates to a component for preventing fluid leakage, especially a seal.

Existing seals 900, such as O-rings, installed between a first member 91 and a second member 92 adjacent to each other to prevent leakage of liquid or gas, such as O-rings, have a circular cross-sectional shape (as shown in FIG. 1). When the sealing element 900 is installed in the groove 911 of the first member 91, the sealing element 900 easily rotates in the groove 911 and causes displacement, resulting in poor sealing effect of the sealing element 900.

Therefore, the purpose of the present invention is to provide a sealing element that does not displace and has a good sealing effect.

Therefore, the seal of the present invention is suitable for tightly abutting between a first member and a second member. The first member has a groove for detachably installing the seal, and the seal includes a The body part and a positioning part.

The body part is used to be embedded in the groove of the first member.

The positioning portion extends upward from the main body along a Y direction perpendicular to the groove, and includes two mutually connected and extending opposite to each other along an X direction perpendicular to the Y direction and used to abut against the first member. The protruding section on the upper surface.

The effect of the present invention is that the sealing element of the present invention abuts against the upper surface of the first member through the positioning portion, so that the sealing element is stably installed in the groove without being rotated and displaced, thereby making the sealing element Has a better sealing effect.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

The seal of the present invention is suitable for tightly abutting between a first member 91 and a second member 92, and the first member 91 has a groove 911 for detachably installing the seal.

Referring to FIG. 2, a first embodiment of the sealing element of the present invention includes a body portion 1 and a positioning portion 2, and the body portion 1 and the positioning portion 2 are integral and continuous.

The body portion 1 is used to be embedded in the groove 911 of the first member 91, and the positioning portion 2 extends upward from the body portion 1 along a Y direction perpendicular to the groove 911. The positioning portion 2 includes two protruding sections 21 that are connected to each other and extend opposite to each other along an X direction perpendicular to the Y direction and used to abut the upper surface 912 of the first member 91, thereby preventing the seal from being The groove 911 rotates and translocates. In order to make the positioning portion 2 more firmly abut the upper surface 912 of the first member 91, preferably, the projected area of the positioning portion 2 in the Y direction is larger than the projected area of the main body 1 in the Y direction. In addition, according to the specific structure of the first member 91 and the second member 92, the shape of the upper surface 22 of the positioning portion 2 can be elastically designed so that the sealing element has a better sealing effect, as shown in FIG. 2, for example. As shown, the positioning portion 2 has an upper surface 22 defined by the top surface 211 of the protruding sections 21 in a circular arc shape. Therefore, when the positioning portion 2 contacts the second member 92, stress ( Under stress), the positioning portion 2 can generate a small strain and also make the sealing member have a good sealing effect.

The width and shape of the main body 1 are not particularly limited, and can be designed elastically according to the shape of the groove 911. For example, to match the shape of the groove 911 and prevent the seal from rotating in the groove 911, as shown in FIG. 2, the width of the body portion 1 along the Y direction is the same from top to bottom, and the The bottom surface of the main body 1 is a flat surface.

Or, as shown in FIGS. 3 and 4, in order to make the sealing member less likely to fall off the groove 911, the width of the body portion 1 gradually increases from top to bottom along the Y direction. With reference to Figure 3, the bottom surface of the main body 1 is a flat surface, and one side of the bottom surface of the main body 1 extends outward along the X direction and the other side shrinks inward along the X direction, except that it can This makes it easier for the seal to be placed in the groove 911, and fits the groove 911 firmly to fit the groove 911, and since the width of the main body 1 gradually increases from top to bottom, The sealing element generates a relatively large reaction force on the surface of the first member 91 defining the groove 911 and has a better supporting force. As shown in FIG. 4, the bottom surface of the body portion 1 is recessed toward the positioning portion 2 along the Y direction. Therefore, when the seal is placed in the groove 911, it can be pressed from the X direction The left and right sides of the main body 1 make the width of the main body 1 smaller than the width of the groove 911, so that the seal can be easily placed in the groove 911, and when the second member 92 moves toward the first member When 91 is pressed down, the two sides of the bottom surface of the main body 1 will be pressed down accordingly to completely fill the groove 911.

Refer to Figure 5, which is a second embodiment of the new sealing element. The difference from Figure 2 of the first embodiment is that, in the second embodiment, the upper surface 22 is formed by the top of the protruding sections 21. The surfaces 211 cooperate to define a two-connected circular arc, which enables the seal installed in the groove 911 to generate a reaction force with a relatively small amount of deformation when being squeezed by the second member 92, In turn, the sealing element has a better sealing effect. The arc length and curvature of the arcs are not particularly limited, and can be adjusted elastically according to the structure of the first member 91 and the second member 92. For example, but not limited to, as shown in FIG. 5, the upper surface 22 has two shapes. Connected and unequal arcs, that is, the arc length and/or radian of one arc is not equal to the arc length and/or radian of the other arc. It can be understood that the shape of the upper surface 22 that is two connected and equal arcs (not shown in the figure) is also an equivalent variation of the second embodiment.

It should also be noted that according to the specific shapes of the first member 91 and the second member 92, the body portion 1 and the positioning portion 2 of the seal of the present invention can be elastically matched. Therefore, in the second embodiment, the width and shape of the main body 1 are not limited to the structure shown in FIG. 5, and may also be the structure of the main body 1 shown in FIGS. 3 and 4, that is, the first The equivalent changes of the second embodiment are shown in FIG. 6 and FIG. 7.

Refer to Figure 8, which is a third embodiment of the new sealing element. The difference from Figure 2 of the first embodiment is that in the third embodiment, the positioning portion 2 has a protruding section 21 The top surface 211 cooperates to define the upper surface 22 of two-spaced arcs, which enables the seal installed in the groove 911 to be squeezed by the second member 92. The deformation produces a reaction force, which in turn makes the sealing element have a better sealing effect. The arcs may be equal to each other, the arc lengths are not equal, the arcs are not equal, or the arc lengths and the arcs are not equal.

In addition, in the third embodiment, the width and shape of the main body 1 are not limited to the structure shown in FIG. 8, and may also be the structure of the main body 1 shown in FIGS. 3 and 4, that is, the first The equivalent changes of the three embodiments are shown in FIG. 9 and FIG. 10.

The sealing element of the present invention has elasticity and is made of elastic material, such as but not limited to fluorine rubber, silicon rubber, etc. The specific aspect of the sealing element of the present invention is, for example, but not limited to, an O-ring in a closed loop.

To sum up, the sealing element of the present invention abuts against the first member 91 through the positioning portion 2, so that the sealing element is not easy to rotate and displace when it is accommodated in the groove 911, so that the sealing element has a relatively high Good sealing effect. In addition, the positioning portion 2 can further define the upper surface 22 of different shapes by the protruding sections 21, so that the tightness between the sealing element and the first member 91 and the second member 92 is increased. , So that the seal has a better sealing effect. In addition, the sealing element can also be modified by changing the structure of the main body 1 to make the sealing element easier to be embedded in the groove 911 and not easy to fall off. Therefore, the objective of new cost can be achieved.

However, the above are only examples of the present model, and should not be used to limit the scope of implementation of the present model, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
