It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the scope of protection of the utility model.

[0041] refer to Figures 1 to 4 The utility model provides a threaded sealing structure, including a main body 1 and a sealing cover 2. The outer wall of the main body 1 is provided with a mounting hole 10, and the inner wall of the mounting hole 10 is provided with a first extrusion portion 11 and a first threaded portion 12. The first extrusion portion 11 is located at a side of the mounting hole 10 away from the main body 1, and the first extrusion portion 11 is provided with a plurality of first abutment rings 111 arranged at intervals; the sealing cover 2 passes through the tent cloth 4 and is connected to the main body 1, and the outer wall of the sealing cover 2 is correspondingly provided with a second extrusion portion 21 and a second threaded portion 22, and the second threaded portion 22 matches the first threaded portion 12, and the second extrusion portion 21 is correspondingly provided with a plurality of second abutment rings 211, and the second abutment rings 211 are suitable for abutting with the first abutment ring 111 and abutting and fixing the tent cloth 4 between the first extrusion portion 11 and the second extrusion portion 21.

[0042] In this embodiment, the main body 1 and the sealing cover 2 are locked and connected by the first threaded portion 12 and the second threaded portion 22, so that the first abutment ring 111 on the first extrusion portion 11 and the second abutment ring 211 on the second extrusion portion 21 are squeezed and abutted against each other, which greatly increases the locking force of the first extrusion portion 11 and the second extrusion portion 21, has a stronger sealing effect, higher reliability, and can effectively prevent air leakage and water seepage.

[0043] Specifically, refer to Figure 5 , the first threaded portion 12 is arranged along the central axis of the installation channel 10, the first extrusion portion 11 is connected to the end of the first threaded portion 12 away from the main body 1, when the first threaded portion 12 and the second threaded portion 22 are screwed and locked, the first extrusion portion 11 and the second extrusion portion 21 are relatively extruded and abutted and the tent cloth 4 is pressed tightly, and the sealing cover 2 is highly reliable after installation and is not prone to loosening or air leakage, which is convenient for installation and disassembly. Moreover, the first threaded portion 12 and the second threaded portion 22 are tightly connected by threads, which can effectively prevent moisture and dust from entering the interior, keep it dry and clean, and extend the service life, while also improving the overall waterproof performance of the tent. Preferably, the first extrusion portion 11 extends to the end away from the main body 1 and is relatively away from the central axis of the installation channel 10, that is, the first extrusion portion 11 is an inclined surface, and the second extrusion portion 21 is also a corresponding inclined surface. The inclined surfaces of the first extrusion portion 11 and the second extrusion portion 21 are more resistant to the force, and can withstand higher internal pressure, which is conducive to offsetting the torsion of the shaking of the sealing cover 2 and preventing the sealing cover 2 from loosening. The first extrusion portion 11 is provided with a plurality of first abutment rings 111, which are arranged in sequence at intervals along the radial direction of the installation channel 10 and the central axes of the plurality of first abutment rings 111 are all the central axes of the installation channel 10, and correspondingly, the second extrusion portion 21 is also provided with a plurality of second abutment rings 211, and each first abutment ring 111 abuts against its corresponding second abutment ring 211, thereby increasing the contact area between the first extrusion portion 11 and the second extrusion portion 21, effectively improving the sealing performance, thereby reducing the number of inflations and energy consumption, and achieving the purpose of energy saving. It is worth noting that the thread arrangement of the first threaded portion 12 and the second threaded portion 22 is not further described in this application. It is worth noting that, according to different usage requirements and scene requirements, a variety of threaded sealing structures of different specifications and forms can be designed to meet the usage requirements in various application scenarios.

[0044] Further, refer to Figures 5 to 7The first abutment ring 111 protrudes toward the side away from the first extrusion portion 11, and the first abutment ring 111 protrudes toward the side away from the second extrusion portion 21; the first abutment ring 111 includes a first radial section 1111 and a first axial section 1112, the first axial section 1112 is arranged along the central axis of the mounting hole 10, and the end of the first radial section 1111 is connected to the first axial section 1112; the second abutment ring 211 includes a second axial section 2111 and a second radial section 2112, the second axial section 2111 is arranged along the central axis of the mounting hole 10, and the end of the second axial section 2111 is connected to the second radial section 2112; the second radial section 2112 is suitable for abutting with the first radial section 1111 and pressing the tent cloth 4, and a first accommodating cavity 24 for accommodating the tent cloth 4 is reserved between the first axial section 1112 of the first extrusion portion 11 and the second axial section 2111 of the next second extrusion portion 21.

[0045] In the present embodiment, when the first threaded portion 12 and the second threaded portion 22 are tightened, the first radial section 1111 of the first abutting ring 111 first abuts against the second radial section 2112 of the second abutting ring 211 to press the tent cloth 4, so that the tent cloth 4 is firmly fixed between the first abutting ring 111 and the second abutting ring 211; at the same time, because the first abutting ring 111 and the second abutting ring 211 are arranged in sequence along the radial direction of the mounting channel 10, a first accommodating cavity 24 for accommodating the tent cloth 4 is reserved between the first axial section 1112 of the first extrusion portion 11 and the second axial section 2111 of the next second extrusion portion 21, and the first accommodating cavity 24 reserves deformation of the tent cloth 4 to prevent the tent cloth 4 from being squeezed and damaged.

[0046] Specifically, the first radial section 1111 at the top of the first abutment ring 111 and the second radial section 2112 at the bottom of the second abutment ring 211 abut against each other, the second axial section 2111 is located on the side of the second radial section 2112 away from the mounting hole 10, the first axial section 1112 is located on the side of the first radial section 1111 close to the mounting hole 10, and the first abutment rings 111 are arranged in sequence at intervals along the radial direction of the mounting hole 10, so that a preset distance is left between adjacent first abutment rings 111, and at this time, a first accommodating cavity 24 is left between the first axial section 1112 of the previous first abutment ring 111 and the second axial section 2111 of the next second abutment ring 211, and the next second abutment ring 211 abuts against the next first abutment ring 111. Preferably, the first accommodating cavity 24 is diamond-shaped. When the first extrusion portion 11 and the second extrusion portion 21 squeeze the tent cloth 4, the first accommodating cavity 24 can accommodate the compressed and deformed tent cloth 4, and reserve deformation amount for the tent cloth 4. The tent cloth 4 is not easily deformed or broken, thereby preventing the pressure loss of the tent cloth 4 from causing the main body 1 and the tent cloth 4 to separate.

[0047] Further, refer to Figure 7The head end of the first radial segment 1111 extends to the side away from the main body 1 to the end of the first radial segment 1111, the head end of the second radial segment 2112 is suitable for abutting against the first extrusion portion 11, and the end of the first radial segment 1111 is suitable for abutting against the end of the second radial segment 2112, so that a second accommodating cavity 25 for accommodating the tent cloth 4 is left between the second radial segment 2112 and the first radial segment 1111.

[0048] In this embodiment, the first radial segment 1111 is relatively inclined, and the head end of the second radial segment 2112 forms a line and surface abutment with the first extrusion portion 11, and the clamping force is stronger; the end of the first radial segment 1111 is suitable for forming a line and line abutment with the end of the second radial segment 2112, which greatly enhances the sealing performance of the two ends of the second radial segment 2112; at the same time, a second accommodating cavity 25 for the tent cloth 4 is reserved between the second radial segment 2112 and the first radial segment 1111, further reserving the deformation amount of the tent cloth 4.

[0049] Specifically, the head end of the first radial segment 1111 and the head end of the second radial segment 2112 are the side of the first radial segment 1111 away from the axis of the mounting hole 10, the end of the first radial segment 1111 and the end of the second radial segment 2112 are the side of the first radial segment 1111 close to the axis of the mounting hole 10, the head end of the first radial segment 1111 extends to the side away from the main body 1 to the end of the first radial segment 1111, that is, the end of the first radial segment 1111 is tilted relative to the head end of the first radial segment 1111, and a certain angle is formed between the first radial segment 1111 and the second radial segment 2112. When the head end of the second radial segment 2112 is suitable for abutting against the first extrusion portion 11 and the end of the first radial segment 1111 is suitable for abutting against the end of the second radial segment 2112, this angle forms a second accommodating cavity 25. During installation, the first end of the second radial segment 2112 forms a line and surface abutment with the first extrusion portion 11, and the end of the first radial segment 1111 is suitable for forming a line and line abutment with the end of the second radial segment 2112. The first end of the second radial segment 2112 and the end of the second radial segment 2112 are subjected to greater force, achieving a better sealing effect. Also because the first end of the second radial segment 2112 is suitable for contacting the first extrusion portion 11 and the end of the first radial segment 1111 is suitable for contacting the end of the second radial segment 2112 first, the first accommodating cavity 24 just reserves space for the deformation of the tent cloth 4, and the sealing performance is better while ensuring reliability.

[0050] Further, refer to Figure 3 and Figure 4 The mounting hole 10 is also provided with a first placement portion 13, which is connected to one end of the first extrusion portion 11 away from the first threaded portion 12. A second placement portion 23 is also provided on the outer wall of the sealing cover 2, which is connected to one end of the second extrusion portion 21 away from the second threaded portion 22. The second placement portion 23 is suitable for being placed on the first placement portion 13.

[0051] In this embodiment, the second placement portion 23 is suitable for being placed on the first placement portion 13. At this time, the sealing cover 2 cannot be twisted again, which reminds the user that the sealing cover 2 and the mounting channel 10 have been installed. It also prevents the first abutting ring 111 and the second abutting ring 211 from being overly squeezed and deformed, avoids damage to the first abutting ring 111 and the second abutting ring 211, and increases the number of recycling times of the sealing cover 2. Specifically, the first placement portion 13 is located at an end of the first extrusion portion 11 away from the mounting channel 10, the first placement portion 13 is arranged along the radial direction of the mounting channel 10, and the second placement portion 23 matches the first placement portion 13. When the second placement portion 23 abuts against the first placement portion 13, the sealing cover 2 and the mounting channel 10 are fixedly installed.

[0052] Further, refer to Figure 8 The sealing cover 2 is axially penetrated with an air inlet channel 20, and a plurality of fixing columns 201 are provided on the inner wall of the air inlet channel 20, and the fixing columns 201 are arranged at intervals along the circumference of the air inlet channel 20; it also includes a rotary cover 3, and a plurality of locking columns 31 are provided at one end of the rotary cover 3, and a fixing groove 311 is provided on the locking column 31, and the fixing column 201 is snapped into the fixing groove 311 by rotating the rotary cover 3.

[0053] In this embodiment, the rotary cover 3 is rotated and disassembled and installed on the air inlet channel 20 through the fixing groove 311 of the locking column 31 and the fixing column 201 on the inner wall of the air inlet channel 20, which facilitates opening the rotary cover 3 to connect the air inlet channel 20 with the outside, prevents dust and foreign matter from entering the accommodating cavity, and protects the internal parts of the main body.

[0054] Specifically, a circular ring 202 is further provided in the air inlet channel 20, and the circular ring 202 is connected to one end of the fixing column 201 away from the inner wall of the air inlet channel 20, so that an insertion channel 203 is left between the outer wall of the circular ring 202 and the inner wall of the air inlet channel 20, and the locking column 31 is suitable for passing through the insertion channel 203, and the outer wall of the circular ring 202 is suitable for abutting against the inner wall of the locking column 31. During installation, the locking column 31 of the rotary cover 3 passes through the insertion channel 203, and then the rotary cover 3 is rotated to make the fixing column 201 enter the fixing groove 311, so that the rotary cover 3 can be quickly removed and installed on the sealing cover 2.

[0055] Preferably, reference Fig. 9 , a placement groove is also provided on the outer wall of the rotary cover 3, and a sealing ring 32 is sleeved on the placement groove, and the placement groove can effectively prevent the sealing ring 32 from moving. After the rotary cover 3 is installed, the sealing ring 32 is suitable for abutting against the top of the air inlet channel 20, and the rotary cover 3 and the sealing cover 2 are sealed to prevent gas from leaking between the rotary cover 3 and the sealing cover 2. In a modified embodiment, the sealing ring 32 can also be directly sleeved on the outer wall of the rotary cover 3. Moreover, the sealing ring 32 can also abut against the inner wall of the ring 202, which are all easy to think of by those skilled in the art, and are all within the protection scope of this application.
