Description

Technical Field

[0001] This utility model belongs to the technical field of screw air compressor accessories, specifically relating to a flexible multi-outlet air supply structure for screw air compressors. Background Technology

[0002] A screw air compressor is an air compressor that uses screw compression technology. Screw air compressors are pre-configured, requiring only a single power connection and compressed air connection, and have a built-in cooling system, greatly simplifying installation. Screw air compressors consistently provide high-quality compressed air to various industries due to their high efficiency, maintenance-free operation, and high reliability. The oil-air mixture discharged from the compressor is separated into compressed air for supply to users. However, under high volume and high pressure conditions, excessive vibration in the compressor's air supply pipe can easily damage the connections at both ends if flexible tubing is used. Furthermore, different user-end devices have different interfaces, and standard air supply structures do not meet the diverse compatibility requirements. Utility Model Content

[0003] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a flexible multi-outlet air supply structure for screw air compressors.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A flexible multi-outlet compressed air supply structure for a screw air compressor includes an air supply pipeline connector. Two fixing plates are installed at the bottom of the air supply pipeline connector. A first elbow is connected to the output end of the air supply pipeline connector. An air pipe is connected to the flange of the first elbow. A second elbow is connected to the flange of the air pipe. An adapter is connected to the output end of the second elbow. The adapter communicates with a cover. Several air outlet cylinders are connected to the lower side of the cover. A bottom cylinder is connected to the lower side of the lowest air outlet cylinder. Ear plates are evenly distributed around the perimeter of the cover. The bottom cylinder has rectangular tubes whose positions and numbers correspond to the ear plates. Fixing holes are provided in both the rectangular tubes and the fixing plates. Through holes are provided in both the rectangular tubes and the ear plates. A lead screw is placed in each through hole. Forks are symmetrically provided at the lower end of the lead screw. Fork blocks are fitted to the forks. The fork blocks are larger than the through holes. Nuts are fitted to the threads of the lead screw.

[0006] The lower side of the cover is integrally connected with a cover protrusion ring. The air outlet and the bottom cylinder are both provided with grooves of specifications and dimensions that match the cover protrusion ring. The upper side of the air outlet and the bottom cylinder are integrally connected with a side ring located inside the cover protrusion ring. The outer side of the side ring is clearance-fitted with the inner side of the cover protrusion ring.

[0007] The air outlet is equipped with a quick-connect connector and a flange connector.

[0008] Furthermore, both the gas supply pipe connector and the quick-connect fitting are equipped with a pressure gauge mounting port. This design allows for the installation of a pressure gauge, enabling real-time monitoring of the corresponding gas pressure and ensuring smooth and accurate operation.

[0009] Furthermore, the trachea is a rigid metal tube and is equipped with multiple spare parts of different lengths. This design ensures high durability while also providing strong resistance to shaking and good connection capabilities for the rigid parts.

[0010] Furthermore, the air outlet has at least three outlets. This design allows for a greater number of corresponding air supply connectors, resulting in better compatibility.

[0011] Furthermore, sealing rings are installed between the convex ring and the groove of the cover, as well as between the convex ring and the side ring, to ensure airtightness.

[0012] The beneficial effects of using this utility model are as follows:

[0013] By adopting the structural design of this utility model, a rigid connection and rigid pipe are used at the output end of the air compressor, which directly improves the shock resistance during operation, ensures the overall structural strength, and thus ensures the service life.

[0014] By adopting the structural design of this utility model, the number of air supply ports can be increased by installing different numbers of air outlets and using air pipes of corresponding lengths, thereby adapting to more connection needs.

[0015] The structural design of this utility model allows the air outlet to rotate, thereby enhancing the connection adaptability. Attached Figure Description

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown, this utility model discloses a flexible multi-outlet compressed air supply structure for a screw air compressor, including an air supply pipe connector 1. Two fixing plates 2 are installed at the bottom of the air supply pipe connector 1. A first elbow joint 3 is connected to the output end of the air supply pipe connector 1. An air pipe 4 is flanged to the first elbow joint 3. A second elbow joint 5 is flanged to the air pipe 4. An adapter 6 is connected to the output end of the second elbow joint 5. The adapter 6 is connected to a cover 7. Several air outlet cylinders 8 are connected to the lower side of the cover 7, located at the lowest side. The bottom cylinder 9 is connected to the lower side of the air outlet 8. Ear plates 10 are evenly provided around the cover 7. The bottom cylinder 9 has rectangular tubes 11 whose positions and numbers correspond to the ear plates 10. Both the rectangular tubes 11 and the fixing plate 2 have fixing holes 12. The rectangular tubes 11 and the ear plates 10 have through holes 13. A lead screw 14 is placed in the through hole 13. The lower end of the lead screw 14 has symmetrical forks 15. Forks 16 are matched and installed in the forks 15. The size of the forks 16 is larger than that of the through hole 13. The lead screw 14 is threaded and matched with nuts 17.

[0025] The lower side of the cover 7 is integrally connected with a cover protrusion ring 18. The air outlet 8 and the bottom cylinder 9 are both provided with grooves 19 of specifications and dimensions that match the cover protrusion ring 18. The upper side of the air outlet 8 and the bottom cylinder 9 is integrally connected with a side ring 20 located inside the cover protrusion ring 18. The outer side of the side ring 20 is in clearance fit with the inner side of the cover protrusion ring 18.

[0026] The air outlet 8 is equipped with a quick-connect connector 21 and a flange connector 22.

[0027] In this embodiment, when using a flexible multi-outlet air supply structure for a screw air compressor, the air supply pipe connector 1 is connected to the compressed air output end of the screw air compressor. The compressed air from the screw air compressor flows through the air supply pipe connector 1, then through the air pipe 4 and the adapter 6 into the interior of the cover 7. The cover 7, several air outlet cylinders 8, and the bottom cylinder 9 form a large cavity, which serves as a diversion carrier for multiple outlets. The fixing plate 2 and rectangular tube 11 installed on the lower side of the bottom cylinder 9 and the air supply pipe connector 1 can reinforce the position of the bottom cylinder 9 and the air supply pipe connector 1, share the vibration force when the gas passes through during use, and thus ensure the connection stability of the air pipe 4. The air pipe 4 uses a first elbow connector 3 and a second elbow connector 5 at both ends, which makes the air pipe 4 highly resistant to vibration.

[0028] After the gas passes through the cavities in the cover 7, the outlet 8, and the bottom cylinder 9, it is exhausted through the pipes connected by the quick-connect connector 21 or the flange connector 22. It should be noted that the quick-connect connector 21 or the flange connector 22 that is not connected must be sealed to ensure the normal internal pressure. The multiple outlets achieve the purpose of flexible gas supply.

[0029] The structure of multiple air outlets 8 allows the entire air supply to be adjusted by adding or removing quick-connect connectors 21 and flange connectors 22 as needed. The air outlets 8 are installed in a longitudinal stacking manner. After determining the number of air outlets 8, the screw 14 is inserted into the through hole 13 with the end of the fork 15 facing downwards. After the fork 15 enters the rectangular tube 11, the fork block 16 is inserted into the fork 15. Then, the nut 17 is screwed onto the screw 14 exposed on the upper side of the ear plate 10 until the nut 17 is rotated to the bottom and contacts the upper side of the ear plate 10. Under this tension, the connection strength of the cover 7, air outlets 8 and bottom tube 9 is high, and the airtightness is also guaranteed with the cooperation of the cover convex ring 18, groove 19 and side ring 20.

[0030] Both the preferred gas supply pipe connector 1 and the quick-connect connector 21 are equipped with a pressure gauge installation port 23. This design allows for the installation of a pressure gauge, enabling real-time detection of the corresponding gas pressure and ensuring smooth and accurate operation. In practice, the installation of a pressure gauge or gas instrument can be considered depending on the specific circumstances.

[0031] The preferred trachea 4 is a rigid metal tube, and it is equipped with multiple spare parts of different lengths. This design is not only durable, but also provides strong anti-shaking and connection capabilities for the rigid parts. In fact, the material selection of trachea 4 can also be considered according to specific circumstances.

[0032] Ideally, there should be at least three air cylinders 8. This design allows for a greater number of corresponding air supply connectors and better compatibility. In practice, the number of air cylinders 8 can also be considered based on specific circumstances.

[0033] It is preferred that sealing rings 24 are installed between the convex ring 18 and the groove 19 of the cover body, and between the convex ring 18 and the side ring 20 of the cover body. This design ensures airtightness. In fact, the style of sealing ring 24 and other airtight measures can also be considered according to specific circumstances.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
