Examples
FIG. 1 is a schematic view of a second side 110b of a seal 100 according to an embodiment of the present invention; fig. 2 is a schematic cross-sectional view of a seal 100 in accordance with an embodiment of the present invention. Referring to fig. 1 and 2, the present embodiment provides a sealing member 100, which is disposed on a first component and contacts a second component to seal a gap between the first component and the second component, and the sealing member 100 is a closed structure extending in a circumferential direction. In the present embodiment, the first member may be a door or a cover or the like that is detachable, and the second member may be a structure having an opening, such as a door frame, a cup opening or the like, although the seal 100 may be provided to the other of the two members. The seal 100 of the present embodiment includes:
a seal body 110, the seal body 110 extending circumferentially of the seal 100 to close, the seal body 110 having opposite first and second sides 110a, 110b;
the sealing part 120 arranged on the first side 110a of the sealing body 110, the sealing part 120 comprises a first protrusion 122 and a second protrusion 124 which are arranged at intervals, the first protrusion 122 and the second protrusion 124 protrude towards a direction away from the sealing body 110, and the first protrusion 122 and the second protrusion 124 extend along the circumferential direction of the sealing member 100 to be closed; the first protrusion 122 and the second protrusion 124 are for contact with the second member, and the first protrusion 122 and the second protrusion 124 have elasticity.
The first side 110a and the second side 110b in this embodiment are opposite sides in a direction perpendicular to a closing plane formed by the sealing body 110, rather than the inner and outer sides of the closed sealing body 110. When the first protrusion 122 and the second protrusion 124 contact the wall surface to be sealed, contact deformation occurs, and due to the existence of restoring force, the first protrusion 122 and the second protrusion 124 continuously provide pretightening force, so that a better sealing effect is achieved. Because the two protrusions seal together, when one of them fails or the sealing effect is poor, the other will continue to maintain the sealed state.
In this embodiment, the seal body 110, the first protrusion 122 and the second protrusion 124 form a closed ring structure, and the first side 110a and the second side 110b are disposed at intervals in the axial direction of the ring formed by the seal body 110.
It should be appreciated that the shape of the closure structure formed by the seal body 110, seal 120, etc. should be determined by the opening edge profile of the desired seal, or the location where the seal 100 is desired to be installed. In other embodiments of the present invention, the overall shape of the seal body 110 may be a rectangular closed structure, with the first protrusion 122 and the second protrusion 124 also forming a rectangular closed structure; or the seal 100 may be integrally formed as an oval-shaped closure structure.
In the present embodiment, the first protrusion 122 and the second protrusion 124 are disposed at intervals in the radial direction of the seal body 110, and the first protrusion 122 is close to the inner side of the seal body 110 with respect to the second protrusion 124.
In the present embodiment, the sealing part 120 further includes a third protrusion 126 disposed between the first protrusion 122 and the second protrusion 124, and the third protrusion 126 is closed by extending along the circumferential direction of the sealing body 110. The third protrusion 126 has a protrusion direction identical to the protrusion directions of the first protrusion 122 and the second protrusion 124. The third protrusion 126 also has elasticity so that it can continuously press against the wall surface to be sealed when contacting the wall surface to provide a good sealing effect.
Further, the third protrusion 126 has a protrusion height smaller than the respective protrusion heights of the first protrusion 122 and the second protrusion 124. The third protrusion 126 may have a radial dimension slightly larger than the radial dimensions of the first protrusion 122 and the second protrusion 124, such that the third protrusion 126 is more difficult to deform relative to the first protrusion 122 and the second protrusion 124. So that when the sealing portion 120 is pressed, the third protrusion 126 can play a role in both sealing and limiting: when the third protrusion 126 abuts against the wall surface, the seal 100 is difficult to further compress, and the first protrusion 122 and the second protrusion 124 are not excessively deformed to be damaged. This ensures a useful life of the seal 100, such that the contact deformation is within a controllable range.
The outermost side in the radial direction of the seal body 110 is provided with a fourth protrusion 128, the fourth protrusion 128 facing in accordance with the protruding direction of the first protrusion 122 and the second protrusion 124, the fourth protrusion 128 extending around the circumferential direction of the seal body 110 to be closed. The outer side of the fourth protrusion 128 is flush with the outer side of the sealing body 110. The fourth protrusion 128 has a thickness in the radial direction smaller than the first protrusion 122, the second protrusion 124, and the third protrusion 126. The free end of the second protrusion 124 is attached to the wall surface to be sealed to eliminate the gap in appearance, and if the fourth protrusion 128 is not provided, the outer side of the second protrusion 124 cannot be attached to the wall surface to form the gap, so that the appearance is affected, and dust, impurities and the like may enter the sealing portion 120 to affect the sealing effect.
The inner side of the seal body 110 in the radial direction is provided with a mounting groove 112, the mounting groove 112 extending in the circumferential direction of the seal body 110 to communicate end to end, the mounting groove 112 being for cooperation with the first member, i.e. for better mounting of the seal 100. In this embodiment, the mounting groove 112 is formed on the inner side of the sealing body 110, and the mounting groove 112 may be hooked on the outer edge of the component during assembly, and the outer edge of the component is inserted into the mounting groove 112, so as to ensure the stability and reliability of the sealing member 100. In other embodiments of the present invention, the mounting groove 112 may be omitted, or the mounting position thereof may be opened to the second side 110b of the sealing body 110, so long as the mounting groove 112 can be engaged with the protrusion structure of the position to be mounted.
In this embodiment, the seal body 110, the seal portion 120, and the like are integrally formed, and are made of rubber having good elasticity, such as nitrile rubber, natural rubber, silicone rubber, ethylene propylene rubber, or fluorinated rubber.

Referring to fig. 3 and 4, and referring to fig. 1 and 2, the present embodiment further provides a door structure 200, which includes a frame 210 having an opening, a door 220 matching with the opening of the frame 210, and the sealing member 100. The door structure 200 may be applied to maintain a seal between a door and a rack to which it is mounted. The door 220 is sealingly engaged with the opening edge of the frame 210 by the sealing member 100. In this embodiment, the frame 210 corresponds to the second member as mentioned above, and the door 220 corresponds to the first member, the sealing member 100 is fixedly disposed on the door 220, and the side of the sealing portion 120 faces the frame 210. It should be appreciated that in other embodiments of the present invention, the sealing member 100 may be installed at the opening edge of the frame 210, with the side of the sealing portion 120 facing the door 220.
In the present embodiment, the door 220 is substantially circular, and the mounting portion 222 is provided along an edge of the door 220, and the mounting portion 222 is plate-shaped and extends around a circumferential side of the door 220 to form a ring shape. When the sealing member 100 is fastened to the door 220, the mounting portion 222 can be inserted into the mounting groove 112 on the inner side of the sealing member 100, and thus the two are fixedly connected, and the side of the sealing portion 120 faces the frame 210.
In summary, the seal member according to the embodiments of the present invention is configured to be disposed on the first member and contact with the second member to seal a gap between the first member and the second member, and the seal member is a circumferentially extending closed structure, and includes a seal body and a seal portion disposed on the seal body.
