Description

Technical Field

[0001] This utility model relates to the field of fluid control and sealing technology, specifically to a threaded cap flip-over air valve. Background Technology

[0002] The nozzle and valve body of inflatable products are core components for airflow control. They achieve precise regulation of the inflation and deflation process through valve mechanisms and rely on sealing components to prevent gas leakage and ensure stable air pressure. Their materials must be suitable for different working conditions; for example, high-temperature resistant synthetic rubber is used in automobile tires (≤260℃), and corrosion-resistant silicone is used in medical inflatable mattresses to meet the needs of high-load or corrosive environments. The nozzle generally uses a one-way valve design, allowing only unidirectional gas flow.

[0003] The existing technology has the following shortcomings: The air valve structure used in existing inflatable products seals the gas inside the inflatable product through a one-way sealing structure. However, when the gas flows at high speed during deflation, it will generate a whistling noise, and the inner material of the inflatable product will be carried to the air vent by the high-speed gas flow, which can easily cause blockage of the air vent. When the existing air valve structure is used in inflatable products such as sponges that cannot be automatically deflated, it cannot suck air out of them, resulting in poor flexibility and versatility in use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a threaded cap flip-over air valve, which solves the problems of whistling noise during air release and poor versatility and flexibility.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a threaded cap flip valve, comprising a fluid controlled port, a circular connecting strip, an adhesive strip, and a skirt. The circular connecting strip is disposed around the fluid controlled port, the adhesive strip is disposed on the side end of the fluid controlled port, the skirt is disposed on the outside of the fluid controlled port, and a sealing cap is disposed on the side end of the circular connecting strip.

[0006] The end of the adhesive strip is provided with a flip control valve, and the side of the flip control valve is provided with an air nozzle.

[0007] The tilt control valve also includes threads, locking blocks, a mounting frame, and a one-way sealing plug. The threads are formed on both sides of the tilt control valve. The locking blocks are fixedly connected to both ends of the tilt control valve. The mounting frame is fixedly connected to the middle of the inner side of the tilt control valve. The one-way sealing plug is inserted into the middle of the mounting frame.

[0008] As a preferred embodiment of this utility model, a circular through hole is provided in the middle of the mounting frame, and four sets of hollow grooves are provided around the circular through hole. A strip-shaped structure is provided in the middle of the one-way sealing plug, and the structure is inserted into the circular hole in the middle of the mounting frame.

[0009] As a preferred technical solution of this utility model, the two sides of the flip control valve have the same structure and are connected to the sealing cover by a threaded connection.

[0010] As a preferred embodiment of this utility model, the fluid-controlled port further includes an anti-blocking isolation ring, a connecting ring, a rubber ring, and a barrier strip. The anti-blocking isolation ring is fixedly installed on the side end of the fluid-controlled port, and the connecting ring is fixedly installed on the opposite side end face of the fluid-controlled port.

[0011] As a preferred technical solution of this utility model, the rubber ring is snapped into the groove at the side end of the fluid controlled port, and two sets of the barrier strip are provided and fixedly connected to both ends of the through groove in the middle of the fluid controlled port, and are in a parallel state to each other.

[0012] As a preferred technical solution of this utility model, the anti-blocking isolation ring is an overall ring structure with an irregular through groove on its side end, and the connecting ring is connected to the flip control valve through the movable connection with the locking block.

[0013] As a preferred embodiment of this utility model, the outer end of the adhesive strip has a conical structure and is inserted into the side of the flip control valve, and the skirt is made of soft rubber material.

[0014] Compared with the prior art, this utility model provides a threaded cap flip-over air valve:

[0015] A threaded cap flip-over air valve, comprising a flip-over control valve, an anti-clogging isolation ring, a mounting frame, a one-way sealing plug, a barrier strip, a connecting ring, and a locking block, allows the operator to install the fluid-controlled port onto the outside of the gas-sealing material via the skirt. To inflate, the operator opens the sealing cap, rotates the flip-over control valve until the side of the one-way sealing plug with the strip-shaped protrusion faces outward, and then locks the flip-over control valve onto the fluid-controlled port by rotation. The air nozzle is then locked onto the outside of the flip-over control valve in the same manner, allowing inflation to proceed. Gas is pushed up by the one-way sealing plug and blocked and dispersed by the barrier strip as it passes through the fluid-controlled port. After inflation, the air nozzle is removed and the sealing cap is tightened. To deflate, the operator simply opens the sealing cap and removes the flip-over control valve. If the applicable material is sponge or another non-automatically venting material, the sealing cap is opened, the flip-over control valve is rotated to the other side, and then the air nozzle is installed on the side of the flip-over control valve to evacuate the internal air.

[0016] Through the above settings and procedures, this structure can achieve the following beneficial effects:

[0017] 1. By combining the barrier strip, rubber ring, and anti-blocking isolation ring, the high-speed gas flow inside the structure can avoid the whistling noise generated by the high-speed gas. The anti-blocking isolation ring can block the material from the inside of the installation material, ensuring gas flow while preventing internal materials from approaching and blocking the gas outlet, thereby improving the operational stability of the structure.

[0018] 2. By combining the flip control valve and the one-way sealing plug, this structure allows for the switching between inflation and deflation simply by flipping the valve quickly, compared to existing gas control valves. This not only makes the operation simple and flexible, but also enables its application to structures that cannot automatically deflate, thus improving the versatility of the structure.

The circular connecting strip 2 is disposed around the fluid controlled port 1, the adhesive strip 3 is disposed on the side of the fluid controlled port 1, the skirt 4 is disposed on the outside of the fluid controlled port 1, and a sealing cap 5 is disposed on the side of the circular connecting strip 2.

[0027] The end of the rubber strip 3 is provided with a flip control valve 6, and the side end of the flip control valve 6 is provided with an air nozzle 7.

[0028] The tilt control valve 6 also includes a thread 601, a locking block 602, a mounting frame 603, and a one-way sealing plug 604. The thread 601 is formed on both sides of the outer periphery of the tilt control valve 6. The locking block 602 is fixedly connected to both ends of the tilt control valve 6. The mounting frame 603 is fixedly connected to the middle of the inner side of the tilt control valve 6. The one-way sealing plug 604 is inserted into the middle of the mounting frame 603.

[0029] In this embodiment, a circular through hole is provided in the middle of the mounting frame 603, and four sets of hollow grooves are provided around the circular through hole. A strip structure is provided in the middle of the one-way sealing plug 604, and the structure is inserted into the circular hole in the middle of the mounting frame 603. The flip control valve 6 has the same structure on both sides and is movably connected to the sealing cover 5 by the thread 601.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the strip-shaped structure in the middle of the one-way sealing plug 604, after being inserted into the middle of the mounting frame 603, can ensure a stable connection of the one-way sealing plug 604, while the threads 601 on both sides of the flip control valve 6 allow it to quickly establish a connection with the sealing cover 5.

[0031] In this embodiment, the fluid controlled port 1 further includes an anti-blocking isolation ring 101, a connecting ring 102, a rubber ring 103, and a barrier strip 104. The anti-blocking isolation ring 101 is fixedly installed on the side end of the fluid controlled port 1, and the connecting ring 102 is fixedly installed on the opposite side end face of the fluid controlled port 1. The rubber ring 103 is snapped into the groove at the side end of the fluid controlled port 1. Two sets of barrier strips 104 are provided and are fixedly connected to both ends of the through groove in the middle of the fluid controlled port 1, and are in a parallel state to each other.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, two sets of barrier strips 104 intercept high-speed gas from the middle of the fluid controlled port 1 and disperse the gas to prevent the generation of howling noise.

[0033] In this embodiment, the anti-blocking isolation ring 101 has an overall ring structure, and an irregular through groove is provided on its side end.

[0034] The working principle and usage process of this utility model are as follows: When using this structure, the operator installs the fluid-controlled port 1 on the outside of the gas-sealing material via the skirt 4. When the operator needs to inflate the interior, the sealing cover 5 is opened, and the flip control valve 6 is rotated until the side with the strip-shaped protrusion in the middle of the one-way sealing plug 604 faces outward. Then, the flip control valve 6 is rotated and snapped onto the fluid-controlled port 1. The air nozzle 7 is then snapped onto the outside of the flip control valve 6 in the same way, and inflation can then begin. When the gas passes through the one-way sealing plug 604, it is pushed up. When the gas passes through the fluid-controlled port 1, it is blocked and dispersed by the barrier strip 104. After inflation is complete, the air nozzle 7 is removed and the sealing cover 5 is tightened. When the operator needs to deflate, simply open the sealing cover 5 and remove the flip control valve 6 to deflate normally. If the applicable material is sponge or other structures that cannot automatically vent, the sealing cover 5 is opened and the flip control valve 6 is rotated to the other side. Then, the air nozzle 7 is installed on the side of the flip control valve 6 to evacuate the interior.
