Description

Technical Field

[0001] This utility model relates to the technical field of corrugated hoses, specifically a high-sealing and pressure-resistant gas corrugated hose. Background Technology

[0002] Corrugated hoses, as a type of flexible pressure-resistant pipe fitting, are installed in liquid transportation systems to compensate for the mutual displacement of pipe or machine equipment connection ends, absorb vibration energy, and play a role in vibration reduction and noise reduction. They have many characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance, and resistance to high and low temperatures.

[0003] For example, the stainless steel corrugated hose for leak-proof gas transmission with authorization announcement number "CN221075596U" solves the problems of aging, wear, and leakage that easily occur during the use of existing stainless steel corrugated hoses for leak-proof gas transmission. The leak-proof component is set in the joint of the aforementioned stainless steel corrugated hose for leak-proof gas transmission, which can effectively improve the safety and reliability of gas transmission. Considering that the existing stainless steel corrugated hoses for leak-proof gas transmission have a corrugated surface with a corrugated expansion and contraction effect, when faced with external force squeezing the surface, the corrugation will not support the external force evenly, and it is easy to deform and cannot easily return to its original shape, resulting in inconvenience in use. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing stainless steel corrugated hoses for leak-proof gas transmission have uneven support for external forces, are easily deformed, and cannot be easily restored to their original shape, resulting in inconvenience in use. Therefore, this invention proposes a high-sealing and pressure-resistant corrugated gas hose.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing and pressure-resistant gas corrugated hose, including a flange and a fixing hole. The outer wall of the flange is machined with a fixing hole. The upper end of the flange is fixedly connected to a connector. The inner wall of the flange is machined with a connecting groove. The inner wall of the connector is threadedly connected to a threaded ring. The outer wall of the threaded ring is connected with a reinforcing mechanism.

[0006] Preferably, the reinforcement mechanism includes an outer corrugated pipe, the end of which is fixedly connected to a threaded ring, the inner wall of which is fixedly connected to a first reinforcement ring, and the inner wall of which is fixedly connected to an inner corrugated ring.

[0007] Preferably, the inner wall of the connecting groove abuts against the rubber ring, and the outer wall of the rubber ring is connected to a sealing mechanism.

[0008] Preferably, the sealing mechanism includes a rubber sleeve, the outer wall of which is fixedly connected to a rubber ring, the inner side of which is fixedly connected to a sealing ring, the inner wall of which abuts against a connecting strip, and the inner wall of which is fixedly connected to a spring.

[0009] Preferably, the inner wall of the inner corrugated ring is fixedly connected to the second reinforcing ring.

[0010] Preferably, the end of the spring is fixedly connected to the rubber ring.

[0011] The present invention proposes a high-sealing and pressure-resistant gas corrugated hose, the advantages of which are as follows: the outer corrugated ring and the first reinforcing ring of the gas corrugated hose buffer the external force on the inner corrugated ring. There is also sealed air between the outer and inner corrugated rings to further buffer the external force. In addition, the second reinforcing ring inside the inner corrugated ring provides external force support. Due to the rebound force of the first and second reinforcing rings themselves, the automatic recovery state of the outer and inner corrugated rings is improved, making it more convenient to use.

[0019] The present invention will be further described below with reference to the accompanying drawings: Example

[0020] Please see Figure 1-6 In this embodiment, a high-sealing and pressure-resistant gas corrugated hose includes a flange 1 and a fixing hole 2. The fixing hole 2 is machined on the outer wall of the flange 1. The upper end of the flange 1 is fixedly connected to the connector 3. The connecting groove 4 is machined on the inner wall of the flange 1. The inner wall of the connector 3 is threadedly connected to the threaded ring 5. The outer wall of the threaded ring 5 is connected to a reinforcing mechanism 6.

[0021] The reinforcement mechanism 6 includes an outer bellows 601, which forms an isolation distance with the inner bellows ring 603, so that the outer bellows 601 and the inner bellows ring 603 form a buffer reinforcement effect. The end of the outer bellows 601 is fixedly connected to the threaded ring 5, and the inner wall of the outer bellows 601 is fixedly connected to the first reinforcement ring 602. The first reinforcement ring 602 is made of ABS plastic and has good resilience. The inner wall of the outer bellows 601 is fixedly connected to the inner bellows ring 603.

[0022] The outer corrugated ring 601 and the first reinforcing ring 602 of the gas corrugated hose buffer the external force on the inner corrugated ring 603. There is also sealed air between the outer corrugated ring 601 and the inner corrugated ring 603 to buffer the external force again. In addition, the second reinforcing ring 9 inside the inner corrugated ring 603 provides external force support. Due to the rebound force of the first reinforcing ring 602 and the second reinforcing ring 9, the automatic recovery state of the outer corrugated ring 601 and the inner corrugated ring 603 is improved, making it more convenient to use.

[0023] The inner wall of the connecting groove 4 abuts against the rubber ring 7. The outer wall of the rubber ring 7 is connected to a sealing mechanism 8. The sealing mechanism 8 includes a rubber sleeve 801. The sealing ring 802 is compressed by the spring 804, so that the sealing ring 802 can fit tightly against any object of any size, ensuring the sealing performance of the connection. The outer wall of the rubber sleeve 801 is fixedly connected to the rubber ring 7. The inner side of the rubber sleeve 801 is fixedly connected to the sealing ring 802. The inner wall of the sealing ring 802 abuts against the connecting strip 803. The inner wall of the connecting strip 803 is fixedly connected to the spring 804.

[0024] The inner wall of the inner corrugated ring 603 is fixedly connected to the second reinforcing ring 9. The second reinforcing ring 9 is made of ABS plastic and has good resilience. The end of the spring 804 is fixedly connected to the rubber ring 7.

[0025] Working principle:

[0026] By inserting the rubber ring 7 into the connecting groove 4, the sealing mechanism 8 on the rubber ring 7 is installed inside the flange 1. When the external structure is fixed with the fixing hole 2 on the flange 1 using screws, when the connector of the external pipe is inserted into the flange 1, the outer wall of the silicone sealing ring 802 will adhere to the outer surface of the external pipe, and the spring 804 pushes the connecting strip 803 to squeeze the sealing ring 802, ensuring that the sealing ring 802 fits more tightly with the connection. At the same time, during the tightening process of the sealing ring 802, the sealing ring 802 will also pull the rubber sleeve 801 to expand and contract, ensuring high sealing performance of the connection.

[0027] When external pressure occurs, the outer corrugated ring 601 and the first reinforcing ring 602 of the gas corrugated hose will buffer the external force on the inner corrugated ring 603. There is also a sealed space between the outer corrugated ring 601 and the inner corrugated ring 603, which will be compressed and buffer the external force on the inner corrugated ring 603 again. The second reinforcing ring 9 inside the inner corrugated ring 603 will also provide external force support. The first reinforcing ring 602 and the second reinforcing ring 9, made of ABS plastic, provide pressure resistance to the outer corrugated ring 601 and the inner corrugated ring 603.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
