Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a vibration-resistant gas hose with variable pitch corrugations, including a protective sleeve 1, a connecting disc 2 fixedly connected to the right side of the protective sleeve 1, a quick-connect pipe mechanism 4 provided on the left end of the outer wall of the protective sleeve 1, the quick-connect pipe mechanism 4 is used for sliding installation of the pipe joint for easy quick installation and removal, an appliance connector mechanism 6 is provided on the right side of the connecting disc 2, a sealing mechanism 7 is provided on the left end of the protective sleeve 1, a protective mechanism 8 is provided inside the protective sleeve 1, a gas pipe 3 is provided inside the protective mechanism 8, and a segmented variable pitch mechanism 5 is provided on the outer wall of the gas pipe 3, the segmented variable pitch mechanism 5 is used to set corrugated sections with different pitches to improve the vibration resistance;

[0035] The quick-installation mechanism 4 for pipes includes a tray 401. The inner wall of the tray 401 is fixedly connected to the left end of the outer wall of the protective sleeve 1. A sleeve 402 is fixedly connected to the left side of the tray 401. Two sliding grooves 403 are opened inside the sleeve 402. Two slide rails 404 are fixedly connected to the left side of the outer wall of the protective sleeve 1. A pipe joint 405 is fixedly connected to the left side of the sleeve 402. A pneumatic component 406 is provided on the top of the pipe joint 405. A locking component 407 is provided on the right side of the sleeve 402.

[0036] Specifically, the quick-installation mechanism 4 is located on the left side of the outer wall of the protective sleeve 1 and is fixedly installed on the left side of the outer wall of the protective sleeve 1 via a tray 401. It is used to provide a stable base for the quick-installation structure. The left side of the tray 401 is fixedly connected to the sleeve 402, which serves as a guide and bearing structure for the pipe joint 405. The sleeve 402 has two grooves 403 inside, which are used to achieve sliding guide cooperation with the slide rail 404. The left side of the outer wall of the protective sleeve 1 is provided with two slide rails 404, which are inserted into the grooves 403 respectively, forming a limiting sliding structure between the sleeve 402 and the protective sleeve 1 to ensure a smooth installation path and consistent insertion direction.

[0037] The left side of the sleeve 402 is fixedly connected to the pipe joint 405. During use, it can slide along the slide groove 403 and the slide rail 404 to the designated position to complete the insertion process. The top of the pipe joint 405 is provided with a pneumatic component 406, which is used to strengthen the seal at the joint by adjusting the air pressure, adapting to the gas pressure requirements under different connection conditions, and improving the stability and airtightness of the interface. The right side of the sleeve 402 is provided with a locking component 407. After the pipe joint 405 is slid and installed, the locking component 407 fixes its position to prevent the connector from loosening and falling off due to vibration, airflow impact and external pulling.

[0038] Through the structural cooperation of the slide groove 403 and the slide rail 404, the quick insertion and guidance of the pipe joint 405 is realized. The pneumatic component 406 controls the airtightness of the joint, and the locking component 407 completes the structural locking, preventing the connector from shaking and accidentally falling off. This allows the entire quick-connect pipe mechanism 4 to achieve efficient insertion, stable sealing and structural locking without relying on the threaded rotation structure, which is suitable for working conditions with confined spaces and frequent connections.

[0039] Reference Figure 5 and Figure 6 The segmented variable pitch mechanism 5 includes a flexible buffer corrugation 501. The inner wall of the flexible buffer corrugation 501 is fixedly connected to the left end of the outer wall of the gas pipe 3. A neutral transition corrugation 502 is provided on the right side of the flexible buffer corrugation 501. A rigid support corrugation 503 is fixedly connected to the right end of the outer wall of the gas pipe 3. An outer protective layer 504 is fixedly connected to the outer wall of the flexible buffer corrugation 501.

[0040] Specifically, the segmented variable pitch mechanism 5 is installed on the outer wall of the gas pipe 3. The inner wall of the flexible buffer corrugation 501 is fixedly connected to the left end of the outer wall of the gas pipe 3 to provide elastic buffering to reduce stress concentration when the pipe is subjected to force and vibration. A neutral transition corrugation 502 is provided on the right side of the flexible buffer corrugation 501 to connect different structural segments and mitigate the stress abrupt change caused by the change in rigidity and flexibility. A rigid support corrugation 503 is fixedly connected to the right end of the outer wall of the gas pipe 3 to provide sufficient structural support near the terminal interface to prevent deformation and breakage.

[0041] The outer wall of the flexible buffer corrugation 501 is fixedly connected with an outer protective layer 504, which is used to cover the outer surface of the corrugation to resist external wear, corrosion and impact. Through the segmented combination of the flexible buffer corrugation 501 and the rigid support corrugation 503, the synergistic effect of structural buffering and terminal support of the pipeline in the vibration environment is realized.

[0042] By setting the neutral transition corrugation 502, the corrugated structure forms a composite response of flexibility and rigidity in the variable pitch connection area, which improves the fatigue resistance of the pipeline under complex working conditions. The connection between the outer protective layer 504 and the flexible corrugated structure increases the protective performance while ensuring the flexible deformation capability, thus extending the overall service life and stability of the pipeline.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The pneumatic assembly 406 includes a sensing column 4061, the bottom of which is fixedly connected to the top of the pipe joint 405. A pressure gauge 4062 is fixedly connected to the top of the sensing column 4061. The locking assembly 407 includes two positioning pins 4071, the left sides of which are fixedly connected to the front and rear ends of the right side of the sleeve 402. The front and rear ends of the left side of the tray 401 are provided with pin points 4072. The appliance connector mechanism 6 includes an external thread 601, the left side of which is fixedly connected to the right side of the connecting disc 2.

A buffer assembly 604 is provided on the left side of the nut 602.

[0044] Specifically, the air pressure assembly 406 includes a sensing column 4061. The bottom of the sensing column 4061 is fixedly connected to the top of the pipe joint 405. The sensing column 4061 is inserted as a whole with the pipe joint 405 and participates in air pressure status feedback. A pressure gauge 4062 is fixedly connected to the top of the sensing column 4061. The pressure gauge 4062 transmits and displays the current air pressure value at the joint in real time through the sensing column 4061, which is convenient for the operator to judge the sealing status.

[0045] The locking assembly 407 includes two positioning pins 4071. The left sides of the two positioning pins 4071 are fixedly connected to the front and rear ends of the right side of the sleeve 402, respectively. After insertion, the positioning pins 4071 provide structural limit to prevent the joint from loosening. The front and rear ends of the left side of the tray 401 are provided with pin points 4072. The pin points 4072 are inserted and engaged with the positioning pins 4071 to achieve quick mechanical locking after sliding, avoiding connection shaking and misalignment.

[0046] The appliance connector mechanism 6 includes an external thread 601. The left side of the external thread 601 is fixedly connected to the right side of the connecting disc 2, serving as the connection end between the overall pipeline and the appliance. The right side of the external thread 601 is threadedly connected to a nut 602. After the nut 602 is tightened, the clamping end face presses against the appliance interface to form a stable connection force. The right side of the nut 602 is fixedly connected to a threaded sleeve 603, which extends the connection length and strengthens the axial fixation of the connector. A buffer component 604 is provided on the left side of the nut 602. The buffer component 604 absorbs the impact of the rotational torque during the tightening process, preventing damage to the sealing surface and stress accumulation.

[0047] The linkage between the sensing column 4061 and the pressure gauge 4062 enables real-time feedback of the air pressure status, improving safety. The structural cooperation between the positioning pin 4071 and the pin point 4072 completes the mechanical limit locking after the joint slides into place, preventing it from falling off. The combination of the external thread 601, nut 602 and threaded sleeve 603 forms a stable and reliable appliance connection structure, ensuring sealing and vibration resistance. The buffer component 604 suppresses impact and vibration during the locking process, improving connection durability and interface life.

[0048] Reference Figure 1 , Figure 3 and Figure 4 The buffer assembly 604 includes a buffer ring 6041, the right side of which is fixedly connected to the left side of the nut 602, and a plurality of buffer particles 6042 are fixedly connected to the left side of the buffer ring 6041. The sealing mechanism 7 includes an adhesive film 701, the right side of which is fixedly connected to the left side of the protective sleeve 1, and a sealing ring 702 is fixedly connected to the left side of the adhesive film 701. The protection mechanism 8 includes an adhesive sleeve 801, the outer wall of which is fixedly connected to the inner wall of the protective sleeve 1, and a metal mesh cover 802 is fixedly connected to the inner wall of the adhesive sleeve 801.

[0049] Specifically, the buffer assembly 604 includes a buffer ring 6041, the right side of which is fixedly connected to the left side of the nut 602. The buffer ring 6041 provides flexible buffering to reduce the transmission of thrust when the nut 602 is tightened. Multiple buffer particles 6042 are fixedly connected to the left side of the buffer ring 6041. The buffer particles 6042 disperse the axial impact force during the connection process to prevent structural damage.

[0050] The sealing mechanism 7 includes an adhesive membrane 701. The right side of the adhesive membrane 701 is fixedly connected to the left side of the protective sleeve 1. The adhesive membrane 701 adheres to the external component to form a primary airtight seal. A sealing ring 702 is fixedly connected to the left side of the adhesive membrane 701. The sealing ring 702 adheres to and presses against the inner ring of the connector to form a second layer of sealing protection.

[0051] The protective mechanism 8 includes an adhesive sleeve 801. The outer wall of the adhesive sleeve 801 is fixedly connected to the inner wall of the protective sleeve 1. The adhesive sleeve 801 covers and isolates the gas pipe 3 to improve vibration resistance and wear resistance. A metal mesh cover 802 is fixedly connected to the inner wall of the adhesive sleeve 801. The metal mesh cover 802 acts as a supporting skeleton inside the adhesive sleeve 801 to prevent the inner wall from collapsing and deforming.

[0052] Working principle: The quick-connect mechanism 4 quickly connects the gas hose to the external gas supply pipeline. The inner wall of the tray 401 is fixed to the left end of the outer wall of the protective sleeve 1, providing a stable installation base for the entire quick-connect structure. The sleeve 402 connected to the left side of the tray 401 has two internal sliding grooves 403 that cooperate with two sliding rails 404 on the left side of the outer wall of the protective sleeve 1, allowing the pipe joint 405 to slide smoothly along a predetermined path. When the pipe joint 405 slides to the designated position, the locking component 407 on the right side of the sleeve 402 starts to work. A positioning pin 4071 is inserted into the pin points 4072 at the front and rear ends of the left side of the tray 401 to firmly lock the pipe joint 405, preventing the joint from loosening and falling off due to vibration, airflow impact and external pulling. At the same time, the air pressure component 406 at the top of the pipe joint 405 monitors the air pressure at the joint in real time. The sensing column 4061 transmits the air pressure change to the air pressure gauge 4062 at the top so that the operator can judge the sealing status of the joint and strengthen the seal by adjusting the air pressure to adapt to different gas pressure requirements and ensure the stability of the interface and good airtightness.

[0053] During gas transmission, the segmented variable pitch mechanism 5 plays a crucial role in vibration resistance. This mechanism is located on the outer wall of the gas pipe 3. The inner wall of the flexible buffer corrugation 501 is connected to the left end of the outer wall of the gas pipe 3. When the gas hose is subjected to vibration, external force, and pressure changes, the flexible buffer corrugation 501 generates buffer deformation by its own elasticity, absorbs energy, reduces stress concentration, and reduces damage to the gas pipe 3. The neutral transition corrugation 502 on its right side serves to connect the flexible buffer corrugation 501 with the rigid support corrugation 503, which mitigates the stress abrupt changes caused by the change in rigidity and flexibility in different structural sections, ensuring the continuity and stability of the corrugated structure. The rigid support corrugation 503 at the right end of the outer wall of the gas pipe 3 provides strong structural support near the terminal interface, preventing deformation and breakage of the gas pipe 3 at this location. In addition, the outer protective layer 504 of the outer wall of the flexible buffer corrugation 501 covers the corrugated surface, resists external wear, corrosion, and impact, extends the service life of the gas pipe 3, and ensures that it can work stably for a long time under complex working conditions.

[0054] The connection between the gas hose and the gas appliance is achieved by the appliance connector mechanism 6. The external thread 601 on the right side of the connecting disc 2 is threadedly connected to the nut 602. When the nut 602 is tightened, the threaded sleeve 603 connected on its right side extends the connection length and strengthens the axial fixation of the connector. The nut 602 presses the gas appliance interface with the clamping end face to form a stable connection. The buffer component 604 on the left side of the nut 602 absorbs the impact generated by the rotational torque during the tightening process, avoids damage to the sealing surface and stress accumulation, and ensures the durability of the connection and the service life of the interface. Specifically, the buffer ring 6041 of the buffer component 604 is fixed on the right side of the nut 602 and provides flexible buffering when the nut 602 is tightened to reduce the transmission of thrust. The multiple buffer particles 6042 connected on the left side disperse the axial impact force and prevent damage to the connection structure.

[0055] The sealing mechanism 7 ensures the sealing of the left end of the gas hose. The adhesive film 701 is fixed on the right side of the protective sleeve 1 and adheres to the external components to form a primary gas seal. The sealing ring 702 connected on the left side adheres and presses tightly with the inner ring of the connector to form a second layer of sealing protection. The double seal effectively prevents gas leakage.

[0056] The protective mechanism 8 provides all-round protection for the gas pipe 3. The outer wall of the adhesive sleeve 801 is fixed to the inner wall of the protective sleeve 1, covering and isolating the gas pipe 3, improving the vibration resistance and wear resistance of the gas pipe 3. The metal mesh cover 802 connected to its inner wall acts as a supporting skeleton inside the adhesive sleeve 801, preventing the inner wall of the gas pipe 3 from collapsing and deforming, and ensuring the safety and stability of gas transmission.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
