Description

Technical Field

[0001] This utility model relates to the field of sealing nozzle technology, and more specifically to an internal pressure self-sealing sealing nozzle. Background Technology

[0002] An internal pressure self-sealing nozzle is a type of nozzle that prevents gas leakage when connected to an inflation or deflation device. It is used in equipment or containers that need to maintain gas pressure. The advantage of an internal pressure self-sealing nozzle is that it can provide a reliable sealing effect, reduce the possibility of gas leakage, and thus improve the efficiency and safety of the product.

[0003] Existing internal pressure self-sealing air valves require connecting a rubber plug ring to the air supply pipe during daily use. To ensure airtightness, a rubber gasket is installed at the connection point. However, when depressurizing, the depressurization efficiency is low due to the size of the pipe opening.

[0004] Existing internal pressure self-sealing valves have limitations in daily use. When operators need to control the amount of pressure relief from the valve, they cannot observe the opening size of the pressure relief port, which makes it difficult for them to accurately control the pressure relief efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an internal pressure self-sealing air nozzle to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an internal pressure self-sealing air nozzle, including a sealing air nozzle tube, a rubber plug ring fixedly connected to the outside of the sealing air nozzle tube, a rubber fixing ring fixedly connected to the inside of the rubber plug ring, a rubber pad movably connected to the outside of the rubber fixing ring, anti-slip stripes fixedly connected to the inside of the rubber pad, a metal strip fixedly connected to the outside of the rubber plug ring, a first outer tube of the sealing air nozzle movably connected to the outside of the metal strip, and a scale fixedly connected to the outside of the first outer tube of the sealing air nozzle.

[0007] Furthermore, a first rubber groove is provided on the outside of the sealing air nozzle pipe, and a first rubber ring is movably sleeved inside the first rubber groove.

[0008] Furthermore, a pressure chamber is provided inside the first outer tube of the sealing nozzle, and a spring is provided inside the pressure chamber, with the sealing nozzle tube fixedly connected inside the spring.

[0009] Furthermore, the sealing nozzle tube is externally fixed with an anti-detachment rubber ring, and the anti-detachment rubber ring has a pressure relief hole on its outside.

[0010] Furthermore, a second rubber groove is provided on the outside of the sealing air nozzle pipe, and a second rubber ring is movably sleeved inside the second rubber groove.

[0011] Furthermore, the outer side of the first outer tube of the sealing nozzle is fixedly connected to the second outer tube of the sealing nozzle, and the inner side of the second outer tube of the sealing nozzle is movably connected to the sealing plug tube.

[0012] Furthermore, a tapered pipe is provided inside the sealing plug tube, and a limiting ring is fixedly connected to the outside of the tapered pipe.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model, by incorporating a rubber pad, facilitates the nesting of the rubber pad with the rubber fixing ring installed inside the rubber plug ring using the external groove. This makes it convenient for the operator to install the anti-slip stripes. The anti-slip stripes installed on the outside of the anti-slip stripes allow the sealing nozzle to utilize its flexibility when connecting to the pipeline, ensuring the pipeline's sealing performance. Furthermore, the threads of the anti-slip stripes can cause the internal airflow to spiral out of the pipe, accelerating its flow and thus improving the efficiency of pressure relief.

[0015] 2. This utility model, by providing a scale, facilitates the observation of the pressure relief port size of the sealing nozzle by using the metal strip installed on the rubber plug ring during its extension and retraction movement, in conjunction with the extension and retraction of the metal strip and the scale installed on the outside of the first outer tube of the sealing nozzle. This allows the operator to easily judge the pressure relief size of the sealing nozzle based on the value of the indicator and make adjustments accordingly. Attached Figure Description

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative.

[0022] Reference Figure 1-4 This utility model provides an internal pressure self-sealing nozzle, including a sealing nozzle tube 1, a rubber plug ring 2 fixedly connected to the outside of the sealing nozzle tube 1, a rubber fixing ring 3 fixedly connected inside the rubber plug ring 2, a rubber pad 4 movably connected to the outside of the rubber fixing ring 3, and anti-slip stripes 5 fixedly connected inside the rubber pad 4. This facilitates the nesting of the rubber pad 4 with the rubber fixing ring 3 via the external groove, making it easy for the operator to install the anti-slip stripes 5. The anti-slip stripes 5, installed on the outside of the anti-slip stripes 5, allow the sealing nozzle to maintain the pipe's seal due to its flexibility when connected to the pipeline. The sealing properties, along with the spiral shape of the anti-slip stripes 5, accelerate the internal airflow, thereby improving the pressure relief efficiency. The rubber plug ring 2 is externally fixedly connected to the metal strip 7, and the metal strip 7 is externally movably connected to the first outer tube 8 of the sealing nozzle. The first outer tube 8 of the sealing nozzle is externally fixedly connected to the scale 9. This allows the rubber plug ring 2 to extend and retract via the metal strip 7, and the scale 9 on the outside of the first outer tube 8 of the sealing nozzle can be used to observe the size of the pressure relief port of the sealing nozzle. This makes it convenient for the operator to judge and adjust the pressure relief of the sealing nozzle based on the size of the indicator.

[0023] In a preferred embodiment, a first rubber groove 101 is provided on the outside of the sealing air nozzle pipe 1, and a first rubber ring 102 is movably sleeved inside the first rubber groove 101, which is beneficial to prevent the air pressure inside the pipe from overflowing through the first rubber ring 102 installed through the first rubber groove 101.

[0024] In a preferred embodiment, a pressure chamber 103 is provided inside the first outer tube 8 of the sealing nozzle, and a spring 104 is provided inside the pressure chamber 103. The sealing nozzle tube 1 is fixedly connected inside the spring 104, which is beneficial to control the extension and retraction of the sealing nozzle tube 1 by the spring 104 installed inside the pressure chamber 103, thereby opening or blocking the pressure relief port.

[0025] In a preferred embodiment, an anti-detachment rubber ring 105 is fixedly sleeved on the outside of the sealing nozzle tube 1. The anti-detachment rubber ring 105 has a pressure relief hole 106 on its outside, which facilitates the displacement of the pressure relief hole 106 by moving the sealing nozzle tube 1, thereby opening the sealed nozzle and relieving pressure.

[0026] In a preferred embodiment, a second rubber groove 107 is provided on the outside of the sealing air nozzle pipe 1, and a second rubber ring 108 is movably sleeved inside the second rubber groove 107, which helps to prevent leakage of the air pressure delivered by the sealing air nozzle pipe 1 through the second rubber ring 108 sleeved in the second rubber groove 107.

[0027] In a preferred embodiment, the outer side of the first outer tube 8 of the sealing nozzle is fixedly connected to the second outer tube 109 of the sealing nozzle, and the inner side of the second outer tube 109 of the sealing nozzle is movably connected to the sealing plug tube 110, so that the operator can engage the threads of the sealing plug tube 110 with the threads of the sealing plug tube 110 through the threads inside the second outer tube 109 of the sealing nozzle, thereby fixing the sealing plug tube 110 inside the second outer tube 109 of the sealing nozzle.

[0028] In a preferred embodiment, a tapered pipe 201 is provided inside the sealing plug tube 110, and a limiting ring 202 is fixedly connected to the outside of the tapered pipe 201, which facilitates the closure of the tapered pipe 201 with the tapered tip at the front end of the sealing nozzle tube 1, thereby further sealing the sealing nozzle.

[0029] The working principle of this utility model is as follows: An internal pressure self-sealing air nozzle uses a rubber fixing ring 3 installed inside the rubber plug ring 2 to facilitate the nesting of the rubber pad 4 with the rubber fixing ring 3 through an external groove, thus making it convenient for the operator to install the anti-slip stripes 5. The anti-slip stripes 5 are installed on the outside of the anti-slip stripes 5. The anti-slip stripes 5 allow the air nozzle to maintain the sealing of the pipeline by utilizing its flexibility when connected to the pipeline. The threads of the anti-slip stripes 5 can also accelerate the flow of internal air in a spiral shape, thereby improving the pressure relief efficiency. When the rubber plug ring 2 is in the extension and retraction movement, the metal strip 7 installed on the rubber plug ring 2 can also extend and retract. The extension and retraction of the metal strip 7, in conjunction with the scale 9 installed on the outside of the first outer tube 8 of the air nozzle, allows the operator to observe the size of the pressure relief port of the air nozzle, thus making it convenient for the operator to judge the pressure relief size of the air nozzle and adjust it according to the size of the scale.

[0030] The sealing nozzle tube 1 has a first rubber groove 101 on its outside. A first rubber ring 102 is movably sleeved inside the first rubber groove 101, which helps to prevent air pressure from overflowing from the tube through the first rubber ring 102 installed in the first rubber groove 101. The sealing nozzle first outer tube 8 has a pressure chamber 103 inside. A spring 104 is installed inside the pressure chamber 103. The sealing nozzle tube 1 is fixedly connected inside the spring 104, which helps to control the extension and retraction of the sealing nozzle tube 1, thereby opening or blocking the pressure relief port. An anti-detachment rubber ring 105 is fixedly sleeved on the outside of the sealing nozzle tube 1. A pressure relief hole 106 is opened on the outside of the anti-detachment rubber ring 105, which helps to move the pressure relief hole 106 by moving the sealing nozzle tube 1, thereby opening the sealing nozzle and relieving pressure.

[0031] The sealing nozzle tube 1 has a second rubber groove 107 on its outside. A second rubber ring 108 is movably fitted inside the second rubber groove 107. This helps prevent leakage of the air pressure delivered by the sealing nozzle tube 1 through the second rubber ring 108 fitted inside the second rubber groove 107. The sealing nozzle first outer tube 8 is fixedly connected to the sealing nozzle second outer tube 109. The sealing nozzle second outer tube 109 is movably connected to the sealing plug tube 110 inside. This allows the operator to engage the threads inside the sealing nozzle second outer tube 109 with the threads inside the sealing plug tube 110, thereby fixing the sealing plug tube 110 inside the sealing nozzle second outer tube 109. The sealing plug tube 110 has a tapered pipe 201 inside. A limiting ring 202 is fixedly connected to the outside of the tapered pipe 201. This helps to close the tapered pipe 201 with the tapered tip at the front end of the sealing nozzle tube 1, thereby further sealing the sealing nozzle.
