[0027] This embodiment provides a type of plug seal structure, such as Figures 1 to 2 As shown, the sealing structure installed on the metal fitting 400 includes a single-sided wall 100 and an elastic member 200. The single-sided wall 100 includes a sealing part 110 and a fixing part 120 that are connected to each other. The fixing part 120 is disposed in the mounting groove 410 of the metal fitting 400. The sealing part 110 extends out of the mounting groove 410. The elastic member 200 is disposed between the sealing part 110 and the metal fitting 400.

[0028] During installation, the fixing part 120 is placed in the mounting groove 410, and the sealing part 110 extends out of the mounting groove 410. The elastic force provided by the elastic member 200 enables the single side wall 100 to play a sealing role. The sealing effect can be achieved by a single single side wall 100, reducing the overall size. Moreover, the plug seal structure is a split structure, which makes it convenient to install the plug seal structure on the metal fitting 400 when the mounting groove 410 of the metal fitting 400 is small.

[0029] In some embodiments, the elastic element 200 is a V-shaped spring.

[0030] Understandably, compared to ordinary linear springs, V-shaped springs have a compact structure and can provide effective elastic force in a limited space, which is beneficial for the installation of the sealing structure in a smaller mounting groove 410; V-shaped springs have stronger resistance to deformation and can maintain elasticity under larger loads, thereby improving a more stable sealing force.

[0031] In some embodiments, the sealing structure further includes an O-ring spring 300, which is disposed between the fixing part 120 and the inner wall of the mounting groove 410. As a sealing component, the O-ring spring 300 can increase the elastic pressure of the single-sided wall 100, effectively preventing the leakage of liquid or gas; the O-ring spring 300 can absorb vibration and impact, reduce wear on the sealing surface, and extend service life; generally, the O-ring spring 300 is a skeleton structure, and the O-ring spring 300 can withstand a certain pressure to ensure the sealing effect of the single-sided wall 100.

[0032] In some embodiments, a limiting recess 121 for fixing the O-spring 300 is provided on one side of the fixing part 120. The limiting recess 121 can prevent the O-spring 300 from being displaced during operation, so as to ensure that the relative position between the O-spring 300 and the single-sided wall 100 remains unchanged, and the single-sided wall 100 can maintain a stable sealing effect.

[0033] In some embodiments, a locking block 122 is provided on the side of the fixing part 120 away from the limiting recess 121. The fixing part 120 is locked in the mounting groove 410 by the locking block 122, reducing the probability that the single side wall 100 will slide out of the mounting groove 410.

[0034] In some embodiments, the upper surface of the sealing portion 110 is flush with the upper surface of the main body of the metal fitting 400, so that the sealing portion 110 can apply uniform pressure to the main body of the metal fitting 400 and avoid stress concentration.

[0035] In some embodiments, the end of the sealing portion 110 is provided with a limiting block 111. The limiting block 111 is located on the side of the sealing portion 110 close to the metal fitting 400. The limiting block 111 is used to limit the displacement of the elastic member 200 so as to limit the elastic member 200 between the sealing portion 110 and the metal fitting 400, thereby ensuring the sealing effect.

[0036] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the scope of the present invention. Any person skilled in the art may make some modifications without departing from the scope of the present invention; that is, all equivalent modifications made in accordance with the present invention should be covered by the scope of the present invention.
