[0007] To solve the above-mentioned technical problems, this utility model provides a pressure sensor sealing structure, which includes a connecting seat body; the connecting seat body has an installation groove inside, and a sealing component is provided inside the installation groove;

[0008] The sealing assembly is used to increase the sealing performance of the connector body. The sealing assembly consists of a connecting ring, two sets of moving rings, two sets of first sealing rings and two sets of second sealing rings. The connecting ring is fixedly connected to the inside of the mounting groove. The two sets of moving rings are slidably connected to both ends of the connecting ring. The first sealing ring is fixedly connected to the inside of the moving ring and the second sealing ring is fixedly connected to the outside of the moving ring.

[0009] When using the connector body of this technical solution, the connector head is moved into the interior of the mounting groove, allowing the connector head to connect with the connector body, thus enabling the pressure sensor body to connect with the connector body. When the connector head connects with the mounting groove, it can connect with the moving ring and the connecting ring. Through the compression spring and the connecting ring, the moving ring can be moved, allowing the first sealing ring and the second sealing ring to move. The first sealing ring is tightly attached to the moving ring and the connector head, and the second sealing ring is tightly attached to the moving ring and the mounting groove, thereby increasing the sealing performance of the pressure sensor body installation. At the same time, the first fixing rod is threaded to the connector body, and then the second fixing rod is installed inside the connector body. Through the limiting groove, the second fixing rod is limited and connected to the first fixing rod, thereby stably limiting the first fixing rod inside the connector body, increasing the stability of the pressure sensor body installation.

[0010] Preferably, the external dimensions of the movable ring correspond to the internal dimensions of the mounting groove, and the movable ring and the mounting groove are slidably connected.

[0011] Furthermore, the end of the second sealing ring away from the moving ring is connected to the mounting groove, and multiple sets of compression springs are fixedly connected to the end of the moving ring near the connecting ring. The end of the compression spring away from the moving ring is fixedly connected to the connecting ring.

[0012] Furthermore, a guide groove is provided inside the moving ring near the connecting ring, and guide posts are fixedly connected to both ends of the connecting ring, with the guide groove and guide posts slidably connected.

[0013] A pressure sensor includes the pressure sensor sealing structure as described above. The pressure sensor body is located outside the connector. The pressure sensor body extends into the interior of the mounting groove and is fixedly connected to a connector. The connector is connected to a moving ring and a connecting ring.

[0014] Furthermore, a fixing ring is fixedly connected to one end of the pressure sensor body near the connector. Both ends of the fixing ring are provided with a first fixing rod, and the first fixing rod is threadedly connected to the connector.

[0015] Furthermore, the connecting seat has a second fixing rod threaded on both sides near the pressure sensor body. The first fixing rod has a limit groove inside, and the first fixing rod is limited to the second fixing rod through the limit groove.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The connector body of this utility model, through the design of a sealing component, uses a compression spring in conjunction with a connecting ring to drive the moving ring to shift, allowing the first and second sealing rings to move as well. The first sealing ring is tightly fitted against the moving ring and the connector head, while the second sealing ring is tightly fitted against the moving ring and the mounting groove. This increases the sealing performance of the pressure sensor body. Simultaneously, the first fixing rod is threadedly connected to the connector body, and the second fixing rod is installed inside the connector body, with a limiting groove providing a limiting connection to the first fixing rod. This stably limits the first fixing rod within the connector body, increasing the stability of the pressure sensor body installation. This effectively prevents reduced sealing performance and leakage, and prevents loosening at the connector head during prolonged use or exposure to external vibrations, which could lead to reduced sealing performance, leakage, decreased sensor accuracy, and poor performance.

When the movable ring 5 is displaced, the guide post 10 and the guide groove 9 can guide the movable ring 5 and prevent the movable ring 5 from deviating.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Please refer to the accompanying drawings for details. Figure 1 - Figure 6As shown, a pressure sensor according to an embodiment of the present invention includes the aforementioned pressure sensor sealing structure. The pressure sensor body 11 is located outside the connecting seat body 1. The pressure sensor body 11 extends into the mounting groove 2 and is fixedly connected to a connector 12. The connector 12 is connected to a moving ring 5 and a connecting ring 4. A fixing ring 13 is fixedly connected to one end of the pressure sensor body 11 near the connector 12. Both ends of the fixing ring 13 are provided with first fixing rods 14. The first fixing rods 14 are threadedly connected to the connecting seat body 1. Second fixing rods 15 are threadedly connected to both sides of the connecting seat body 1 near the end of the pressure sensor body 11. A limiting groove 16 is provided inside the fixing rod 14. The first fixing rod 14 is limited to the second fixing rod 15 through the limiting groove 16, which moves the connector 12 into the mounting groove 2 so that the connector 12 is connected to the connector body 1. This allows the pressure sensor body 11 to be connected to the connector body 1. When the pressure sensor is connected to the connector body 1, the first fixing rod 14 is threaded to the connector body 1. At the same time, the second fixing rod 15 is installed inside the connector body 1 and limited to the first fixing rod 14 through the limiting groove 16, thereby stably limiting the first fixing rod 14 inside the connector body 1.
