Example

[0024] See also Figure 1 The figure shows a connecting sealing structure of an air path connector, including a connecting seat 1, a connecting tube 2 is installed on the inner side of the connecting seat 1 through snap-fitting, a sealing seat 3 is connected between the connecting tube 2 and the connecting seat 1 through threads, a No. 1 connecting air pipe 4 is fixedly installed at the rear end of the connecting seat 1, a clamping seat 5 is provided on the inner side of the connecting seat 1, and a No. 2 connecting air pipe 6 is provided at the front end of the connecting tube 2.

[0025] See also Figure 2 In the figure, a groove 101 is provided on the front side of the connecting seat 1, a limiting groove 102 is provided at the front end of the inner side of the groove 101, and a sealing groove 103 is provided at the rear side of the inner side of the groove 101.

[0026] In this embodiment: the groove 101 facilitates the engagement and limiting of the connecting tube 2 during installation. At the same time, the limiting groove 102 facilitates the engagement of the limiting sleeve 8 during the installation of the connecting tube 2, and the No. 1 sealing ring is installed and limited under the action of the No. 1 sealing groove 103.

[0027] Working principle: During the connection and installation, the rear end of the connecting tube 2 is connected and engaged with the connecting seat 1. At this time, the No. 1 sealing ring at the rear end of the connecting tube 2 is engaged with the No. 1 sealing groove 103, which is beneficial to improve the overall sealing during use, and is engaged with the seat 5 and the delivery pipe through the groove 201 and the air hole 202 respectively, which is beneficial to improve the stability and delivery efficiency. Then the rear end of the sealing seat 3 is passed through the connecting tube 2. At this time, the rear end of the sealing seat 3 is engaged with the connecting groove 7. Then the sealing seat 3 is rotated to connect and fix through the internal thread 701 and the external thread, which is beneficial to improve the stability of the connection position between the connecting tube 2 and the connecting seat 1. In the process of rotating the sealing seat 3, the No. 2 sealing ring 902 is driven to move, thereby engaging with the No. 2 sealing groove 801 on the positive side of the limit sleeve 8, thereby forming a second seal, which is beneficial to ensure the sealing effect even if the No. 1 sealing ring is loose during long-term use, thereby improving the overall sealing and service life. Example

[0028] See also Figure 4 This embodiment further explains Example 2. In the figure, a connecting groove 7 is opened on the front side of the connecting seat 1, an internal thread 701 is opened on the inner side of the connecting groove 7, and the size and shape of the connecting groove 7 are consistent with the rear end of the sealing seat 3.

[0029] In this embodiment: by rotating the sealing seat 3, the connection and fixation are conveniently performed under the action of the internal thread 701 and the external thread, which is beneficial to improve the stability of the connection position between the connecting tube 2 and the connecting seat 1. At the same time, under the action of the connecting groove 7, the sealing seat 3 is facilitated to be embedded in the connecting seat 1, thereby improving the overall stability effect and air tightness.

[0030] See also Figure 4 In the figure, a slot 201 is provided at the rear end of the connecting tube 2, and the size and shape of the slot 201 match those of the card seat 5. An air hole 202 is provided on the inner side of the slot 201, and the size and shape of the air hole 202 match those of the delivery pipe on the front side of the card seat 5. A No. 1 sealing ring is provided at the rear end of the connecting tube 2, and the size and shape of the No. 1 sealing groove 103 match those of the No. 1 sealing ring.

[0031] In the present embodiment: the No. 1 sealing ring at the rear end of the connecting tube 2 is engaged with the No. 1 sealing groove 103, which is beneficial to improve the overall sealing during use, and is engaged with the base 5 and the delivery tube respectively through the groove 201 and the air hole 202, which is beneficial to improve the stability and delivery efficiency.

[0032] See also Figure 3 In the figure, a limiting sleeve 8 is fixedly installed at the rear end of the outer side of the connecting tube 2, and a second sealing groove 801 is opened on the positive side of the limiting sleeve 8, and the size and shape of the limiting sleeve 8 match the limiting groove 102.

[0033] In this embodiment: the limiting sleeve 8 is used to facilitate positioning and installation, and at the same time, the sealing seat 3 is installed to resist limiting, which can effectively fix the connecting tube 2 and reduce the leakage when the No. 1 sealing ring is damaged.

[0034] See also Figure 5 In the figure, the sealing seat 3 is in a T-shaped structure, and a through hole 301 is opened on the positive side of the sealing seat 3. The size and shape of the through hole 301 match the connecting tube 2, and the outer side of the sealing seat 3 is provided with anti-slip grooves.

[0035] In this embodiment: through the through hole 301, it is convenient to pass the connecting tube 2 through and connect and fix the connecting tube 2 and the connecting seat 1. At the same time, under the action of the anti-slip groove, it is beneficial to increase the friction when rotating the sealing seat 3, so as to facilitate the rotation.

[0036] See also Figure 6 In the figure, a cavity 9 is opened on the rear side of the sealing seat 3, a baffle 901 is fixedly installed on the inner side of the cavity 9, and a No. 2 sealing ring 902 is fixedly installed on the rear side of the baffle 901. The size and shape of the No. 2 sealing ring 902 match the No. 2 sealing groove 801, and an external thread is opened on the inner side of the cavity 9.

[0037] In the present embodiment: when the sealing seat 3 rotates, the No. 2 sealing ring 902 is driven to move, thereby engaging with the No. 2 sealing groove 801 on the positive side of the limiting sleeve 8, thereby forming a second seal, which is beneficial for ensuring the sealing effect during long-term use even if the No. 1 sealing ring becomes loose, thereby improving the overall sealing performance and service life.
