[0002] With the continuous development of automobiles, heavy commercial vehicles are no longer just a production tool, and more attention is paid to being clean, tidy and comfortable for driving. Most existing commercial vehicles do not have an external air intake device. When it is necessary to blow and clean the components inside and around the cab, a separate device needs to be equipped, or it has one but cannot be quickly disassembled and assembled, which is troublesome to use and operate, and cannot be conveniently stored.

[0003] In the prior art, there is a technology named "Compressed air supply device used in heavy construction equipment" with a publication number of "CN100410522C". This technology is set in a vehicle without an air compressor like a heavy construction equipment, and is used to extract a part of the compressed air provided from the turbocharger to the engine, so as to use the extracted air to clean places such as the vehicle cab. The device includes a turbocharger and a branch pipe connected to the intake pipe. Through the intake pipe, the turbocharger supplies compressed air to the intake main pipe of the engine. The branch pipe is suitable for extracting compressed air from the intake pipe. An air injection device is connected to the distal end of the branch pipe so that when needed, it can inject compressed air to clean the vehicle cab or other parts of the construction equipment. However, this technology does not involve the technical problems and technical solutions of this application. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: aiming at the deficiencies of the prior art, to provide an air intake structure for heavy vehicles with a simple structure, which can be conveniently connected to take air from the vehicle air source, is easy to disassemble and store after taking air, is convenient and labor-saving to operate, and meets the use requirements.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the utility model is:

[0006] The utility model provides an air intake structure for heavy vehicles. The air source pipeline is connected to a self-sealing joint. The self-sealing joint includes a joint body, the joint body includes a first communication port and a second communication port. A spring is arranged in the channel of the joint body near the first communication port, and a one-way valve is arranged in the channel between the spring and the second communication port. The air intake structure for heavy vehicles further includes an air gun and a connecting pipeline.

[0007] The self-sealing joint is installed in the cab of the heavy vehicle through a bracket.

[0008] One end of the connecting pipeline is provided with a first nut connector, and the other end of the connecting pipeline is provided with a second nut connector.

[0009] The first communication port of the self-sealing joint communicates with the gas source pipeline, and a connecting component is arranged outside the second communication port. The connecting component is a screw pipe structure.

[0010] The connecting pipeline is a flexible pipe, and a spiral part is arranged in the middle of the connecting pipeline.

[0011] The check valve abuts against the first limiting step on the side close to the second communication port, the other end of the check valve abuts against one end of the spring, and the other end of the spring abuts against the second limiting step close to the first communication port.

[0012] One end of the check valve close to the second communication port is a conical structure of the check valve, and the first limiting step is a conical structure of the limiting step.

[0013] The first nut end of one end of the connecting pipeline is set to be a structure capable of being screwed and connected to the connecting component of the self-sealing joint.

[0014] The second nut end or the connecting joint of the other end of the connecting pipeline is set to be a structure capable of connecting to the air inlet of the air gun.

[0015] Adopting the technical solution of the present utility model, the working principle and beneficial effects are as follows:

[0016] In the air intake structure of the heavy vehicle described in the present utility model, the gas source pipeline communicates with the vehicle gas source, the gas source pipeline communicates with the first communication port, and the gas source pipeline communicates with the self-sealing joint. When air intake is required, the self-sealing joint is opened, and when air intake is not required, the self-sealing joint realizes self-closure. When air intake is required, one end of the connecting pipeline is connected to the second communication port of the self-sealing joint, and the other end of the connecting pipeline is connected to the air gun. When the connecting pipeline is inserted into the second communication port during connection, a force will be applied to the check valve, pushing the check valve to compress the spring. At this time, the check valve moves backward, and the channel communicates with the second communication port, and the gas can bypass the check valve and enter the connecting pipeline 3 and then enter the air gun to realize gas supply. When air intake is not required, the connecting pipeline is pulled out, and the external force applied by the connecting pipeline to the check valve is eliminated. Under the action of the spring force, the check valve fits the second communication port to realize the closure of the second communication port and realize self-sealing. At this time, the gas will not pass through the self-sealing joint. In this way, air intake can be realized according to needs, and the sealing of the gas source pipeline can be realized when air intake is not required. When not taking air, the connecting pipeline and the air gun are respectively placed in the corresponding hanging and storage positions or storage boxes, without occupying extra space. After taking air, the cab interior and surrounding components can be purged and cleaned through the air gun, which is convenient to use. Description of the Drawings

Specific embodiments

[0021] The following is a further detailed description of the specific embodiments of the present utility model with reference to the drawings, including the shapes, structures of the various components involved, the mutual positions and connection relationships between the various parts, the functions of the various parts, and the working principles, etc.:

[0022] As shown in the attached Figure 1 and attached Figure 2As shown in the figure, the utility model relates to an air intake structure for heavy vehicles. The air source pipeline 1 is connected to the self-sealing joint 2. The self-sealing joint 2 includes a joint body 6. The joint body 6 includes a first communication port 7 and a second communication port 8. A spring 10 is arranged in the channel 9 near the first communication port 7 in the joint body 6, and a one-way valve 11 is arranged in the channel 9 between the spring 10 and the second communication port 8. The air intake structure for heavy vehicles further includes an air gun 4 and a connecting pipeline 3. For the deficiencies in the prior art, the above structure proposes an improved technical solution. When the structure is arranged, the air source pipeline 1 is connected to the vehicle air source to realize gas supply. The air source pipeline 1 is connected to the first communication port 7, and the air source pipeline 1 is connected to the self-sealing joint 2. When air intake is needed, the self-sealing joint 2 is opened, and when air intake is not needed, the self-sealing joint 2 realizes self-closure. When air intake is needed, one end of the connecting pipeline 3 is connected to the second communication port 8 of the self-sealing joint 2, and the other end of the connecting pipeline 3 is connected to the air gun 4. When the connecting pipeline 3 is inserted into the second communication port 8 during connection, a force will be applied to the one-way valve 11, pushing the one-way valve 11 to compress the spring 10. At this time, the one-way valve 11 moves backward, and the channel 9 is connected to the second communication port 8, and gas can bypass the one-way valve 11 and enter the connecting pipeline 3 and then enter the air gun to realize gas supply. When air intake is not needed, the connecting pipeline 3 is pulled out, and the external force applied by the connecting pipeline 3 to the one-way valve 11 is eliminated. Under the action of the force of the spring 10, the one-way valve 11 fits the second communication port 8 to realize the closure of the second communication port 8 and achieve self-sealing. At this time, gas will not pass through the self-sealing joint 2. In this way, air intake can be realized as needed, and the air source pipeline can be sealed when air intake is not needed. When not taking air, the connecting pipeline and the air gun are respectively placed in the corresponding hanging and storage positions or storage boxes, without occupying extra space. After taking air, the cab interior and surrounding components can be blown and cleaned through the air gun, which is convenient to use. The air intake structure for heavy vehicles described in the utility model has a simple structure, can be conveniently connected to realize air intake from the vehicle air source, is convenient for disassembly and storage after taking air, is convenient and labor-saving to operate, and meets the use requirements.

[0023] The self-sealing joint 2 described above is installed in the cab of the heavy vehicle through a bracket 5. In the above structure, the bracket 5 is connected to the heavy vehicle and can be connected by bolts or welding to fix and connect the self-sealing joint to ensure the reliable fixation of the self-sealing joint 2. The self-sealing joint 2 preferably adopts a snap structure, and can be quickly installed and disassembled on the bracket 5 only by manual pressing.

[0024] One end of the connecting pipeline 3 is provided with a first nut connector 12, and the other end of the connecting pipeline 3 is provided with a second nut connector 13. In the above structure, the first nut connector 12 can be conveniently and quickly connected and disassembled with the self-sealing joint, and the second nut connector 13 or the connecting joint can be conveniently and quickly connected and disassembled with the air gun 4 to meet the use requirements. At the same time, the connector can also not adopt a nut structure, but adopt a quick connector in the prior art.

[0025] The first communication port 7 of the self-sealing joint 2 is connected to the gas source pipeline 1, and a connecting component 14 is arranged outside the second communication port 8. The connecting component 14 is of a screw tube structure. When the connecting component 14 is of a screw tube structure, the first nut end 12 at one end of the connecting pipeline 3 is set to be a structure capable of being screwed and connected to the screw tube structure of the self-sealing joint 2, and the second nut end 13 or the connecting joint at the other end of the connecting pipeline 3 is set to be a structure capable of connecting to the air inlet of the air gun 4. With the above structure, the first nut end 12 at one end of the connecting pipeline 3 is convenient for connecting and disassembling with the self-sealing joint, and the second nut end 13 or the quick-connect joint is convenient for connecting and disassembling with the air gun. After disassembly, the air gun and the connecting pipeline are put away without additionally occupying the internal space of the vehicle. The connecting component 14 can also adopt a quick-connect joint. In this case, the first nut end 12 at one end of the connecting pipeline 3 is changed to a plug-in joint to quickly plug and connect with the quick-connect joint of the self-sealing joint 2.

[0026] The connecting pipeline 3 is a flexible tube, and a spiral part 15 is arranged in the middle of the connecting pipeline 3. With the above structure, the spiral part is usually in a spiral contracted state and can be stretched when the air gun is used at a relatively long distance. In this way, it meets the requirements both at a short distance from the gas source and within a certain range at a long distance when using the air gun.

[0027] The one-way valve 11 abuts against the first limiting step 16 on the side close to the second communication port 8, and the other end of the one-way valve 11 abuts against one end of the spring 10, and the other end of the spring 10 abuts against the second limiting step 17 close to the first communication port 7. With the above structure, the first limiting step 16 limits the one-way valve and is also used for sealing and opening between the one-way valve. The second limiting step 17 is used to limit the spring to ensure that the spring is reliably compressed and reset when the extrusion force is eliminated.

[0028] One end of the one-way valve 11 close to the second communication port 8 is a one-way valve conical structure 18, and the first limiting step 16 is a limiting step conical structure 19. With the above structure, under the action of the spring, the one-way valve conical structure 18 of the one-way valve 11 is clamped in the limiting step conical structure 19 to realize the sealing of the gas path and self-sealing. When taking gas, the connecting pipeline applies force to the one-way valve conical structure 18 of the one-way valve, pushing the one-way valve to move backward and compressing the spring. At this time, the one-way valve conical structure 18 and the limiting step conical structure 19 are separated to form a channel, facilitating the gas from the gas source to pass through the gas source pipeline, the channel, and the connecting pipeline and be sent into the air gun to meet the gas-taking requirements.

[0029] The heavy-duty vehicle air intake structure described in the present invention has an air source pipeline 1 connected to the vehicle air source, the air source pipeline 1 is connected to the first connecting port 7, and the air source pipeline 1 is connected to the self-sealing joint 2. When air needs to be taken out, the self-sealing joint 2 is opened, and when air does not need to be taken out, the self-sealing joint 2 is self-sealed. When air needs to be taken out, one end of the connecting pipeline 3 is connected to the second connecting port 8 of the self-sealing joint 2, and the other end of the connecting pipeline 3 is connected to the air gun 4. When the connecting pipeline 3 is inserted into the second connecting port 8, a force is applied to the one-way valve 11, pushing the one-way valve 11 to squeeze the spring 10. At this time, the one-way valve 11 moves backward, and the channel 9 is connected to the second connecting port 8. The gas can bypass the one-way valve 11 to enter the connecting pipeline 3 and then enter the air gun, thereby realizing gas supply. When there is no need to take air, pull out the connecting pipe 3, and the external force applied to the one-way valve 11 by the connecting pipe 3 is eliminated. Under the action of the force of the spring 10, the one-way valve 11 fits the second connecting port 8, and the second connecting port 8 is closed, achieving self-sealing. At this time, the gas will not pass through the self-sealing joint 2. Take air as needed, and seal the air source pipeline when it is not needed. When not taking air, the connecting pipe and the air gun are placed in the corresponding hanging position or storage box respectively, without taking up extra space. After taking air, the interior of the cab and surrounding components can be purged and cleaned with the air gun, which is convenient to use.

[0030] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
