If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figure 1 In an embodiment of the utility model, the sealing cap includes a sealing cap body, a fixing frame 200 and an elastic sealing member 300. The fixing frame 200 is provided with a plurality of hemispherical silicone members 400. The plurality of hemispherical silicone members 400 are mutually staggered to form a shielding layer. The elastic sealing member 300 is installed inside the sealing cap body, and the fixing frame 200 is installed on the elastic sealing member 300. That is, the plurality of hemispherical silicone members 400 are mutually staggered to form a shielding layer and fixed on the upper surface of the elastic sealing member 300 through the fixing frame 200, thereby shielding the upper surface of the elastic sealing member 300. The portion of the puncture cone shielded by the shielding layer is difficult to penetrate, thereby protecting the elastic sealing member 300 and improving the service life of the sealing cap.

[0032] It should be noted that by mutually displacing a plurality of hemispherical silicone members 400 to form a shielding layer, even if the puncture cone squeezes the shielding layer, the shielding layer can effectively block the puncture cone because the plurality of hemispherical silicone members 400 are mutually displaced.

[0033] It is understandable that by adjusting the size of the hemispherical silicone member 400, the size of the shielding layer is changed, thereby adjusting the shielding range of the upper surface of the elastic sealing member 300. That is, by adjusting the size of the hemispherical silicone member 400, the punctureable range of the puncture cone can be changed.

[0034] like Figure 1As shown, the sealing cap body includes an upper cover 100, a base 110 and a fixing ring 120, the upper cover 100 is arranged on the top of the base 110, a first central through hole 101 is provided in the center of the upper cover 100, the base 110 is recessed inward to form an installation cavity, a second central through hole 111 corresponding to the first central through hole 101 is provided at the bottom of the installation cavity, and the fixing ring 120 is used to fix the elastic sealing member 300 to the base 110, wherein the fixing frame 200 and a plurality of hemispherical silicone members 400 are mutually staggered to form a shielding layer located inside the fixing ring 120. In actual use, the puncture cone passes through the first central through hole 101, the fixing frame 200, the elastic sealing member 300 and the second central through hole 111 in sequence.

[0035] It should be noted that the center of the first center through hole 101 and the center of the second center through hole 111 are on the same axis. For example, the first center through hole 101 and the second center through hole 111 are both circular through holes, and the center of the first center through hole 101 and the center of the second through hole are on the same axis.

[0036] It can be understood that the upper cover 100 is provided with card interfaces 102 on both sides of the central through hole, the outer surface of the base 110 is provided with threads, and the outer side wall of the installation cavity is provided with threads.

[0037] Reference Figure 2 The elastic seal 300 includes a fixed groove 310 and a wave-shaped folded floating structure 320 arranged along the outer edge of the fixed groove 310. The fixing frame 200 is installed in the fixed groove 310. The floating structure 320 is used to connect the fixed groove 310 and the sealing cap body. The bottom of the fixed groove 310 is provided with a third central through hole 311. The centers of the first central through hole 101, the second central through hole 111 and the third central through hole 311 are on the same axis. By setting the floating structure 320, the fixed groove 310 can be restored to its original position after being acted upon by an external force, thereby avoiding the elastic seal 300 from being misplaced.

[0038] It can be understood that the floating structure 320 is a two-layer wave-shaped fold, the inner layer of the floating structure 320 is connected to the outer edge of the fixing groove 310, and the outer layer of the floating structure 320 is fixed to the base 110 through the fixing ring 120. Compared with setting one layer of wave-shaped fold, setting two layers of wave-shaped fold has better resilience. Compared with setting three or more layers of wave-shaped fold, setting two layers of wave-shaped fold has a faster rebound speed and occupies a smaller volume.

[0039] like Figure 1 and Figure 2As shown, the fixing frame 200 includes an upper fixing ring 210 and a lower fixing ring 220. The upper fixing ring 210 is provided with a plurality of fixing pillars. The top of the fixing groove 310 is provided with a plurality of fixing through holes 312 corresponding to the fixing pillars one by one. The fixing pillars are connected to the lower fixing ring 220 through the fixing through holes 312. The hemispherical silicone member 400 is located between the upper fixing ring 210 and the elastic sealing member 300.

[0040] Reference Figure 4 The hemispherical silicone member 400 includes a shielding portion 410 and a connecting portion 420. The length of the shielding portion 410 is the length from the top of the fixing groove 310 to the outer edge of the third central through hole 311. The fixing pillar passes through the connecting portion 420 and the fixing through hole 312 in sequence and is connected to the lower fixing ring 220.

[0041] It can be understood that by setting the length of the shielding portion 410 to the length from the top of the fixing groove 310 to the outer edge of the third center through hole 311, the shielding layer can shield other areas of the fixing groove 310 except the third center through hole 311, thereby preventing other areas except the third center through hole 311 from being penetrated by the puncture cone.

[0042] It can be understood that the shielding portion 410 of the hemispherical silicone member 400 can be divided into a first area and a second area, and the first area is located on the right side of the second area. Figure 3 In the embodiment shown, eight hemispherical silicone pieces 400 are provided, namely a first hemispherical silicone piece, a second hemispherical silicone piece, a third hemispherical silicone piece, a fourth hemispherical silicone piece, a fifth hemispherical silicone piece, a sixth hemispherical silicone piece, a seventh hemispherical silicone piece and an eighth hemispherical silicone piece, wherein the second area of ​​the second hemispherical silicone piece covers part of the first area of ​​the first hemispherical silicone piece, the second area of ​​the third hemispherical silicone piece covers part of the first area of ​​the second hemispherical silicone piece, and the second area of ​​the fourth hemispherical silicone piece covers part of the third hemispherical silicone piece. In the first area, the second area of ​​the fifth hemispherical silicone part will cover part of the first area of ​​the fourth hemispherical silicone part, the second area of ​​the sixth hemispherical silicone part will cover part of the first area of ​​the fifth hemispherical silicone part, the second area of ​​the seventh hemispherical silicone part will cover part of the first area of ​​the sixth hemispherical silicone part, the second area of ​​the eighth hemispherical silicone part will cover part of the first area of ​​the seventh hemispherical silicone part, and the second area of ​​the first hemispherical silicone part will cover part of the first area of ​​the eighth hemispherical silicone part. By covering each other, the multiple hemispherical silicone parts can be staggered with each other.

[0043] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
