Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figure 1 - Figure 3 , is the first embodiment of the utility model, which provides a sealing mechanism, including a sealing assembly 100, including a shell 101, a sealing ring 102 used in conjunction with the shell 101, the inner wall of the sealing ring 102 is provided with a sponge pad, and a fixing member 103 and a lifting member 104 are arranged in the shell 101, the sealing ring 102 can be fixed by the fixing member 103, and the sealing ring 102 can be disassembled by the lifting member 104.

[0039] Specifically, the fixing member 103 includes a card slot 103a symmetrically opened on the outer wall of the sealing ring 102, and an installation slot 103b opened inside the housing 101. The installation slot 103b has the same size as the sealing ring 102. A plurality of square slots are symmetrically opened on the surface of the installation slot 103b, and a card block 103c and a first spring 103d symmetrically arranged in the square slot. The card block 103c and the first spring 103d are both installed in the square slot, and the first spring 103d is located between the card block 103c and the square slot, and the card block 103c is reset by the first spring 103d.

[0040] Furthermore, the lifting member 104 includes a connecting rod 104a symmetrically arranged in the installation groove 103b, the connecting rod 104a is slidably installed in the installation groove 103b, and an inclined block 104b and a pressing plate 104c are arranged at both ends of the connecting rod 104a. A plurality of grooves are opened on the outer wall of the shell 101, and the pressing plate 104c is located between the grooves. The inclined surface of the inclined block 104b is arranged on the side close to the sealing ring 102. When the sealing ring 102 is installed, the plurality of inclined blocks 104b will be squeezed to move to both sides, and a second spring 104d is sleeved on the surface of the connecting rod 104a, and the two ends of the second spring 104d are fixedly connected to the pressing plate 104c and the groove in turn. The second spring 104d allows the inclined block 104b to be always in the installation groove 103b when not in use.

[0041] Furthermore, the size and number of the card slot 103a and the card block 103c are consistent. When the sealing ring 102 is installed in the installation groove 103b, the card slot 103a and the card block 103c will engage with each other, thereby fixing the sealing ring 102. The side of the card block 103c close to the card slot 103a is set as an arc surface. Through the setting of the arc surface, the sealing ring 102 can squeeze the card block 103c during installation, so that it moves toward the depth of the square groove. The inclined block 104b is located in the installation groove 103b.

[0042] Operation process: When in use, first assemble the sealing ring 102 with the housing 101, and then install the sealing ring 102 into the installation groove 103b. When the sealing ring 102 is installed, the block 103c and the inclined block 104b are squeezed, so that the inclined block 104b moves to both sides, and the block 103c moves toward the depth of the square groove and squeezes the first spring 103d. After the sealing ring 102 is fully engaged with the installation groove 103b, the reaction force of the first spring 103d pushes the block 103c to reset, so that the block 103c is engaged with the groove 103a, and then the sealing ring 102 is fixed, and then the connector body 301 is inserted between the housing 101 and the sealing ring 102, and the sealing ring 102 is used to seal the connection between the housing 101 and the connector body 301, and the sponge pad is used to make the connection The device body 301 and the sealing ring 102 fit tightly together, thereby improving the sealing performance. When the inclined block 104b moves to both sides, it will also drive the connecting rod 104a to move, and the pressing plate 104c is pushed up from the surface of the shell 101 through the connecting rod 104a, and the second spring 104d is stretched at the same time. When the sealing ring 102 needs to be disassembled, the pressing plates 104c on both sides are pressed synchronously, so that the connecting rod 104a pushes the inclined block 104b to reset, and the sealing ring 102 is squeezed by the inclined surface of the inclined block 104b, so that the sealing ring 102 is pushed outward and the engagement between the card block 103c and the card slot 103a is released, and then the sealing ring 102 can be pulled outward. At the same time, the second spring 104d will also support the inclined block 104b after it is restored, so that it will always be located in the installation slot 103b when not in use.

The soft pad 204c increases the contact area between the rectangular plate 204b and the surface of the connector body 301, so that the connector body 301 can be more The extension block 204d is well fixed and fixedly installed on the opposite side of the rectangular plate 204b, the extension block 204d and the rectangular groove 201 are slidably connected, and a hinge seat 204e is arranged between the extension block 204d and the rotating plate 202, the hinge seat 204e is slidably installed on the bottom of the rotating plate 202, and when the rotating plate 202 rotates, the extension block 204d is pulled by the bottom hinge seat 204e, so that the extension block 204d will also move, and as the rotating plate 202 rotates, the hinge seat 204e will also move.

[0049] Furthermore, the folding block 205b is located directly below the horizontal plate 205c, and the folding block 205b is blocked by the horizontal plate 205c so that it can only rotate to one side. Torsion springs are sleeved on both ends of the folding block 205b, and the folding block 205b can be reset through the torsion springs. A number of rubber blocks are equidistantly arranged on the opposite surfaces of the soft pad 204c, and the friction between the soft pad 204c and the connector body 301 is increased by the rubber blocks.

At the same time, when the rotating plate 202 rotates, it will contact the folding block 205b and squeeze it to deflect it. Then the folding block 205b is reset by the torsion spring, thereby blocking the rotating plate 202 and preventing it from being reset by the third spring 203, thereby fixing the connector body 301. When the connector body 301 needs to be removed from the shell 101, the horizontal plate 205c is pulled backward to release the limit on the folding block 205b. At this time, the reaction force of the third spring 203 makes the rotating plate 202 drive the rectangular plate 204b to reset, and the folding block 205b is reset by the torsion spring, thereby releasing the fixation of the connector body 301.
