[0031] Figure 2 to Figure 6 A first preferred embodiment of the sealing structure of the present invention is shown, said sealing structure is used to install a sealing strip 3, said sealing structure comprises an upper part 1 and a lower part 2, said sealing strip 3 is arranged on said upper part 1 and the lower part 2.

[0032] The lower part 2 forms a sealing strip installation groove 21, and the sealing strip installation groove 21 has a joint area 210. The width of the joint area 210 is greater than twice the width of the sealing strip 3 and does not exceed the sealing strip 3. twice the width of the strip 3 , so that the two joints 31 , 32 of the sealing member 3 can be arranged side by side in the joint area 210 .

[0033] It is worth mentioning that the sealing strip installation groove 21 is annular, and the sealing strip 3 is straight. After the sealing strip 3 is installed in the sealing strip installation groove 21, the two sides of the sealing strip 3 The joint...

[0045] Figure 7 A modified embodiment of the present invention is shown, which is different from the first embodiment in that: the sealing strip installation groove 21 has no outlet. At this time, attention should be paid to the length of the sealing strip 3 when cutting, so as to avoid the length of the sealing strip 3 being too long, so that the joints 31 , 32 cannot be completely installed into the joint area 210 . The advantage of this embodiment is that it prevents the joints 31 and 32 from extending outside the sealing strip installation groove 21 and affecting the appearance of the product.

Abstract

The invention relates to a sealing structure. The sealing structure comprises an upper component and a lower component, wherein the lower component forms a sealing strip mounting slot, a sealing strip is suitable for being mounted in the sealing strip mounting slot, the sealing strip mounting slot is provided with a joint region, and the width of the joint region is larger than one time of the width of the sealing strip and is no more than 2 times of the width of the sealing strip, so as to enable the two joints of the sealing strip to be arranged side by side in the joint region.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a sealing structure. Background technique [0002] In order to achieve a certain IP protection level for the electrical component housing, some kind of elastomer is generally selected as a seal to seal the housing. From the material, the seals can be divided into rubber, styrofoam, etc., and from the form, the seals can be divided into special-shaped seals and standard seals. In order to achieve a higher IP protection level, manufacturers generally design special special-shaped sealing rings, but the production of special-shaped sealing rings requires new molds to form, the cost is high, and the installation of the seals is also relatively complicated. In order to seal the shell, standard seals can also be used, which have the advantages of low cost and convenient purchase, but the disadvantage of using standard seals is that the joints are not easy to handle, and it is difficul...
