Referring to fig. 3, fig. 3 shows a schematic structural diagram of a sealing strip 20 according to the present invention, which is a long strip as a whole, and the structure shown in fig. 3 and fig. 4 is a cross-sectional shape thereof. The weather strip 20 is used for being mounted to a first object and forming a sealing fit with a wall surface of a second object, and mainly includes a mounting portion, a first supporting portion 22, a second supporting portion 25, a third supporting portion 24 and a sealing portion 23, which are respectively formed along a length direction of the weather strip 20.

The mounting portion is used for mounting to a first object, and includes an insertion portion 21 and a base portion 26, the insertion portion 21 is used for being inserted into the first object, and the base portion 26 is used for providing the first support portion 22, the second support portion 25, and the third support portion 24. Specifically, the mating part 21 is a long rib-shaped protrusion structure located below the base part 26, two protruding first tenons 211 and second tenons 212 are respectively arranged on two side walls of the mating part in a cross-sectional view towards the outside to form a dovetail structure, a dovetail groove structure adapted to the dovetail structure is arranged on the first object, and the mating part 21 can be inserted from one end of the dovetail groove and forms a mating relationship with the dovetail groove, so that the sealing strip 20 is restricted from being taken out of the dovetail groove.

After the mating part 21 is mated with the first object, the base part 26 also abuts against the wall surface of the first object outside the dovetail groove on the lower surface (in the direction shown in fig. 4), and can be mated with the mating part 21 to hold the groove wall of the dovetail groove of the first object, thereby further fixing the weather strip 20.

The base portion 26 can be regarded as an elongated plate-shaped member, and of course, the sealing strip 20 is an integrally formed rubber strip, and the above-mentioned different portions are only used for describing the structure of the sealing strip 20, and do not represent the connection relationship between the sealing strip and the base portion, which may be separated or need to be installed. The base portion 26 serves as a base structure of the weather strip 20 for the first support portion 22, the second support portion 25, and the third support portion 24 to be formed on the upper surface thereof.

The first support portion 22 extends in the height direction of the weather strip 20 and is used for connecting the mounting portion and the sealing portion, is substantially directly provided on the upper surface of the base portion 26, has the same length as the base portion 26 of the weather strip 20, and also extends in the vertical direction to form a support wall, the lower end of which is connected to the upper surface of the base portion 26, and may be regarded as a portion on the upper surface of the base portion 26 that is formed by extending and protruding upward; the upper side of the supporting wall is connected to the lower side of the sealing portion 23, and the sealing portion 23 can be regarded as being formed by the upper side of the supporting wall extending convexly upward. The first support portion 22 is used to form a structure having a height in a direction perpendicular to the length of the weather strip 20, so that the sealing portion 23 may have a space for bending, and the sealing portion 23 may reach a position flush with the base portion 26 after abutting against the wall surface of the second object.

The whole sealing portion 23 can be regarded as a long strip-shaped plate-shaped member, the lower side of the sealing portion 23 is connected with the upper side of the first supporting portion 22, and during the forming, the left side wall at the joint of the sealing portion 23 and the first supporting portion 22 is longer than the right side wall, so that the sealing portion 23 is deflected to the right side, in addition, a first yielding groove 221 is arranged on the side wall at the joint bent towards the sealing portion 23, namely, a first yielding groove 221 is arranged on the right side wall, the first yielding groove 221 forms a sinking groove at the bending position of the sealing portion 23, so that the sealing portion 23 is more easily deflected to the right side during the bending, and simultaneously, the deformation pressure on the first supporting portion 22 can be converted into the supporting force of the first supporting portion 22 on the sealing portion 23 during the bending of the sealing portion 23, and further, the first supporting portion 22 is prevented from being deformed.

The surface of the sealing portion 23 facing the second object forms a sealing surface for sealing engagement with the wall surface of the second object, and the sealing portion 23 is bent toward the joint of the sealing portion 23 and the first support portion 22 when the sealing surface abuts against the wall surface of the second object, so that the second support portion 25 biases the sealing portion 23 toward the position where the second object is located within the sealing range of the sealing surface. Specifically, the upper side wall surface of the sealing portion 23 is the above-mentioned sealing surface, which is used to contact with the corresponding wall surface of the second object and tightly abut against the wall surface of the second object, so as to form a sealing fit with the second object. When the second object is tightly attached to the sealing surface, the sealing portion 23 is pushed to bend towards the right side until the second object is bent to a certain angle, and generally, the sealing portion 23 is bent to a position flush with the base portion 26, and at this time, the first supporting portion 22 can have a good support for the sealing portion 23, and the sealing surface can be more completely attached to the second object.

Meanwhile, a second supporting portion 25 is provided, and in the present embodiment, both side edges of the second supporting portion 25 are respectively connected to the mounting portion and the sealing portion 23, and a bending portion 251 is formed at a middle position. In other embodiments, the second supporting portion 25 can be separated from the sealing portion 23, and can be abutted against the lower side wall surface of the sealing portion 23 only when the sealing portion 23 is bent to a predetermined position, and the abutted position is close enough to the first supporting portion 22 so as to provide support for the sealing portion 23. Because the sealing portion 23 has a certain width, and only depends on the support of the first supporting portion 22 at the end portion, when the sealing surface abuts against the second object, the second object may cause the bending angle of the sealing portion 23 to reach below the horizontal position, so that the sealing surface cannot have a sufficient contact area with the second object, resulting in a poor sealing effect. Therefore, by providing the second support portion 25 with another support structure for the sealing portion 23 besides the first support portion 22, the bending angle of the sealing portion 23 can be prevented from reaching below the horizontal position, and the sealing surface can have a sufficient sealing area when abutting against the second object, thereby improving the sealing effect. Moreover, for better effect, according to the deformation property of the material of the sealing strip 20, the distance between the supporting structures formed by the first supporting portion 22 and the second supporting portion 25 can be determined, and the distance should be enough to ensure that when the two supporting structures support the sealing portion 23, the sealing surface and the second object have enough sealing area, and at the same time, the sealing portion 23 does not have obvious recess between the two supporting structures.

In the present embodiment, the second support portion 25 is connected to the lower side wall surface of the sealing portion 23, and a bent portion 251 is provided at a middle position thereof, and when the sealing portion 23 is bent toward the right side, the second support portion 25 is compressed and a large deformation occurs at the bent portion 251, but since the bent portion 251 converts the pressure of the sealing portion 23 on the second support portion 25 into an upward and downward expansion force, the second support portion 25 can support the sealing portion 23. Meanwhile, the second yielding groove 231 is arranged at the joint of the second supporting part 25 and the sealing part 23, the second yielding groove 231 can be arranged at the position (right side) in fig. 3 or at the left side, the effect achieved by the same is the same, a sufficient deformation space is provided for the bending between the second supporting part 25 and the sealing part 23, and meanwhile, the supporting performance of the second supporting part 25 to the sealing part 23 can be improved.

In addition, a third supporting portion 24 is formed on the weather strip 20 along the length direction, and the third supporting portion 24 extends in the height direction of the weather strip 20 and abuts against the sealing portion 23 when the sealing portion 23 is bent to a position where it is in sealing engagement with a second object, so as to limit the sealing portion 23 from being bent continuously. Specifically, the third support portion 24 is disposed on one side of the second support portion 25, and is farther away from the first support portion 22 than the second support portion 25, and is a support wall disposed above the base portion 26, and the height of the upper side of the third support portion is substantially equal to the height of the upper side of the first support portion 22, after the sealing portion 23 is bent, the third support portion 24 can abut against the lower side wall surface of the sealing portion 23, so as to limit the sealing portion 23 from being bent further, and provide support for the sealing portion 23, so that the sealing surface can abut against the second object better.

In addition, the present invention also provides a frame sealing structure, which realizes sealing engagement between the first frame body 32 and the second frame body 31, and which adopts the sealing strip 20 in the above embodiment, and the first object and the second object are the first frame body 32 and the second frame body 31 here.

As shown in fig. 4, the first frame body 32 is provided with a dovetail groove structure which is adapted to the size of the mating part 21 of the weatherstrip 20, the mating part 21 can be mated in the dovetail groove, the second frame body 31 is provided above the first frame body 32 and has a wall surface for sealing engagement with the weatherstrip 20, the wall surface abuts against the sealing surface of the sealing part 23 and bends the sealing part 23 to a position flush with the wall surface, and the third supporting part 24 abuts against the lower side wall surface of the sealing part 23. After the sealing portion 23 is in sealing engagement with the second frame 31, the free end thereof exceeds the edge of the wall surface in sealing engagement therewith, specifically, as shown in fig. 4, the right end of the sealing portion 23 is positioned beyond the edge of the wall surface of the second frame 31 in engagement with the sealing portion 23 in the horizontal direction, so that water can be prevented from accumulating in the weather strip 20.

In addition, since the first support portion 22 itself is not deformed, the outer wall surface of the first support portion 22 is flush with the wall surface of the first frame body 32 in one vertical direction after the weather strip 20 is brought into sealing engagement, so that the appearance of the frame structure after sealing is more beautiful.

The utility model provides a pair of sealing strip and frame seal structure sets up a plurality of bearing structure, makes sealing 23 can not appear deformation when forming sealed cooperation, makes the sealed face of its upside can paste comparatively closely and lean on corresponding seal wall face on the contrary to improve seal area, just also improved sealed effect.
