The height of the top edge of the at least one side wing section along the Y direction is greater than the height of the top edge of the main sealing section along the Y direction, and the volume of the at least one side wing section is smaller than the volume of the main sealing section.

The effect of the present invention is that the sealing element of the present invention increases the contact area with the second member through the side wing section of the tight fitting part, and when the side wing section is pressed down by the second member toward the first member, The main sealing section and the body portion will be stretched homeopathically to press and fit the first member, so that the seal is tightly and smoothly installed in the groove without ups and downs, and the seal and the body can be reduced. The gap between the second members enables the seal and the second member to be closely attached to achieve 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 new type is suitable for abutting between a first member and a second member, and the first member has a groove for the seal to be detachably installed.

Referring to FIG. 2, a first embodiment of the sealing element of the present invention includes a main body 1 and a close part 2, and the main body 1 and the close part 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 sealing portion 2 includes a main sealing portion extending upward from the body portion 1 along a Y direction perpendicular to the groove 911 Section 21, and a side wing section 22 connected to the main sealing section 21 and extending upward in a direction away from the main sealing section 21. The height of the top edge of the side wing section 22 along the Y direction is greater than that of the main sealing section 21. The height of the top edge of the sealing section 21 along the Y direction, and the volume of the side wing section 22 is smaller than the volume of the main sealing section 21.

The seal can penetrate the side wing section 22, so that the seal and the second member 92 have a larger contact area, and the lower surface 921 of the second member 92 gradually moves toward the upper surface 912 of the first member 91 In the process of approaching, the lower surface 921 of the second member 92 first contacts the side wing section 22 of the sealing portion 2 and then contacts the main sealing section 21, and the second member 92 will move the side wing section 22 toward the The upper surface 912 of the first member 91 is pressed down to extend along an X direction perpendicular to the Y direction to be attached to the lower surface 921, so that the main sealing section 21 can be supported by the extension of the side wing section 22. And the body portion 1 is pressed to the first member 91, so that the seal is tightly and smoothly installed in the groove 911, and can be tightly attached to the second member 92 to achieve better Sealing effect.

In some subsequent applications of the present invention, for example, the seal of the present invention is installed in a cavity (not shown) containing the first member 91 and the second member 92, when a pump (not shown) The inside of the cavity is evacuated, because the seal can be tightly attached to the second member 92 through the side wing section 22 and achieve a good sealing effect, so the seal also helps to improve the pump pair The effect of vacuuming the inside of the cavity. In addition, when the pressure inside the cavity is less than the pressure outside the cavity due to being evacuated, the second member 92 will be affected by the pressure outside the cavity and move further to the first The member 91 abuts and fits more closely with the sealing element, thereby further helping to improve the sealing effect.

In order to further increase the contact area between the seal and the lower surface 921 of the second member 92, preferably, the side wing section 22 faces the main sealing section 21 at an angle ranging from 15 degrees to 85 degrees. The direction away from the main sealing section 21 is inclined upward.

The width of the side wing section 22 is not particularly limited. In order to make the side wing section 22 easier to be pressed down by the second member 92 and stretch along the X direction to be attached to the lower surface 921, the adhesion portion 2 is deformed. In addition, there is a larger contact area with the second member 92. Preferably, the width of the side wing section 22 gradually decreases from adjacent to the main sealing section 21 toward a direction away from the main sealing section 21.

The number of the side wing sections 22 is not limited to one, and can be adjusted according to actual usage conditions. For example, in a variation of the first embodiment, in order to further make the sealing element and the second member 92 separate The contact area is increased. As shown in FIG. 3, the sealing portion 2 includes two side wing sections 22 that extend diagonally upward and away from the main sealing section 21.

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, and is not limited to the shape shown in FIGS. 2 and 3. For example, in other variations of the first embodiment, in order to match the shape of the groove 911 and make the seal not easily fall off from the groove 911, as shown in FIGS. 4 and 5, the main body 1 The width of the body portion 1 gradually increases from top to bottom along the Y direction, the bottom surface of the body portion 1 is a flat surface, and one side edge of the bottom surface of the body portion 1 extends outward along the X direction and the other side edge The shrinking in the X-direction not only makes it easier for the seal to be placed in the groove 911, but also fits the shape of the groove 911 and is firmly installed in the groove 911. In addition, due to the body The width of the portion 1 gradually increases from top to bottom, so that the sealing element generates a greater reaction force on the surface of the first member 91 defining the groove 911 and has a better supporting force.

The hardness range of the new seal is not particularly limited, and can be adjusted elastically according to different types of the first member 91 and the second member 92, and the width of the main sealing section 21 can be adjusted elastically according to the hardness of the seal. Referring to Fig. 6, a second embodiment of the new sealing element is different from Fig. 2 of the first embodiment in that, in the second embodiment, when the sealing element has a large hardness, the main seal The width of the joint section 21 is gradually reduced along the Y direction from adjacent to the main body portion 1 toward a direction away from the main body portion 1, so that when the main joint section 21 contacts the second member 92 to generate stress, the main tight joint The section 21 can generate a relatively large strain, which in turn enables the sealing element to have a good sealing effect. In addition, referring to FIG. 7 in conjunction, in a variation of the second embodiment, the sealing portion 2 can also adjust the number of the side wing sections 22 according to the requirements of use, and the sealing portion 2 includes two upward phases. The side wing sections 22 extend back obliquely, so that the sealing element has a better sealing effect.

It should also be noted that, in the second embodiment, the body portion 1 has a width that gradually increases from top to bottom along the Y direction, so that the sealing member cannot easily fall off from the groove 911. Refer to the figure for reference. 8 and FIG. 9, in other variations of the second embodiment, the bottom surface of the body portion 1 is recessed toward the abutment portion 2 along the Y direction, so the sealing member is placed in the groove At 911, by squeezing the left and right sides of the main body 1 from the X direction, the width of the main body 1 is smaller than the width of the groove 911, and the seal can be easily placed in the groove 911 And when the second member 92 is pressed down to the first member 91, the two sides of the bottom surface of the main body 1 will be pressed down accordingly to completely fill the groove 911.

Referring to FIG. 10, a third embodiment of the new type of sealing element is different from FIG. 4 of the first embodiment in that, in the third embodiment, the sealing portion 2 also includes a sealing element that is tightly connected to the main body. The segments 21 are connected and extend along the X direction and abut against the positioning segment 23 of the first member 91, so that the seal is not easily rotated and displaced in the groove 911. In addition, the sealing member makes the sealing portion 2 abut against the upper surface 912 of the first member 91 through the positioning section 23, so that the sealing member can be more compact when being pressed by the second member 92. The amount of deformation produces a reaction force, which in turn enables the seal to have a better sealing effect.

With reference to FIG. 11, in a variation of the third embodiment, the sealing portion 2 can also adjust the number of the side wing sections 22 according to the needs of use, and the sealing portion 2 includes two upwardly opposite slopes. The extended side wing section 22 makes the sealing member have a better sealing effect.

In addition, in other variations of the third embodiment, the width and shape of the main body 1 are not limited to the structure shown in FIGS. 10 and 11, and may also be the main body shown in FIGS. 8 and 9. The structure of the part 1, that is, the equivalent change of the third embodiment is shown in FIG. 12 and FIG. 13.

It should be particularly noted that in the present invention, the structure of the sealing part 2 and the body part 1 can be flexibly matched and combined according to the actual application requirements of the sealing element, and is not limited to the above-mentioned first embodiment to the first embodiment. The aspect shown in the third embodiment, for example, may be the structure of the adhesion portion 2 shown in FIG. 2 with the structure of the body portion 1 shown in FIG. 8, or the structure of the adhesion portion 1 shown in FIG. The structure of the part 2 matches the structure of the main body 1 shown in FIG. 2.

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 present invention is, for example, but not limited to, an O-ring in a closed loop.

In summary, the sealing element of the present invention increases the contact area with the lower surface 921 of the second member 92 through the side wing section 22 of the sealing portion 2, and when the side wing section 22 is moved to the side wing section 22 by the second member 92 When the first member 91 is pressed down in the direction, the main sealing section 21 and the main body portion 1 will be stretched along the way to be pressed against the first member 91, so that the seal is tightly and smoothly installed in the groove 911 Without ups and downs, the gap between the sealing member and the second member 92 can be reduced, so that the sealing member and the second member 92 can be closely attached to achieve a better sealing effect. In addition, the sealing element can also increase the contact area between the sealing element and the second member 92 by adjusting the number of the side wing sections 22, or further change the structure of the sealing part 2 to make the sealing element difficult to rotate and easy to rotate. In turn, the sealing element has a better sealing effect. In addition, the sealing member can also change the structure of the main body 1 so that the sealing member can be more easily embedded in the groove 911 and not easy to fall off, so it can indeed achieve the purpose of new cost.
