Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to an air compressor cooling water pipeline connection structure. Background Technology

[0002] An air compressor is a device used to compress gases. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane, or rotary screw types.

[0003] In the prior art, the cooling water pipes and interfaces connected to the air compressor are usually connected by threads. However, the air compressor generates a lot of vibration when it is working, and the cooling water pipes and interfaces are prone to loosening, which can lead to water leakage and reduce the stability and reliability of the connection between the cooling water pipes and the air compressor. Therefore, we have introduced an air compressor cooling water pipe connection structure. Utility Model Content

[0004] The purpose of this utility model is to provide a cooling water pipeline connection structure for an air compressor, which can prevent the cooling water pipeline and interface connected to the air compressor from becoming loose, thereby improving the stability and reliability of the connection between the cooling water pipeline and the air compressor, and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An air compressor cooling water pipeline connection structure includes an air compressor and a cooling water pipeline. The air compressor has a threaded interface on its side wall. The cooling water pipeline is fitted with an internally threaded sleeve. A limiting ring is fixedly provided on the outer side wall of the cooling water pipeline inside the internally threaded sleeve. The inner side of the internally threaded sleeve is threadedly connected to the threaded interface. The upper and lower sides of the internally threaded sleeve have through holes. A locking rod is slidably provided in the through holes. Both ends of the locking rod extend outside the through holes. The outer side of the threaded interface has a locking groove that cooperates with the locking rod. The rod wall of the locking rod located in the through hole has a reset mechanism. A movable ring is slidably provided on the outer side of the internally threaded sleeve. A linkage mechanism is provided between the movable ring and the locking rod.

[0007] As a further embodiment of this utility model, the reset mechanism includes a positioning rod, and the locking rod has a first strip-shaped hole on its rod wall inside the through hole. The positioning rod is slidably disposed in the first strip-shaped hole on the side away from the threaded interface, and a spring is fixedly provided on the rod wall on the side of the positioning rod away from the threaded interface.

[0008] As a further embodiment of this utility model, the linkage mechanism includes an L-shaped rod, and the locking rod has a second strip-shaped hole on the rod wall outside the internal threaded sleeve. The L-shaped rod is slidably disposed inside the second strip-shaped hole. One end of the L-shaped rod is fixedly connected to the movable ring, and the other end of the L-shaped rod is fixedly provided with a wedge block.

[0009] As a further embodiment of this utility model, a first sealing ring is fixedly provided at the end of the internal threaded sleeve near the air compressor.

[0010] As a further embodiment of this invention, a second sealing ring is fixedly provided at the end of the limiting ring away from the air compressor.

[0011] As a further embodiment of this invention, the first sealing ring and the second sealing ring are configured as corrosion-resistant rubber rings.

[0012] As a further embodiment of this invention, the locking rod has a bevel at one end near the threaded interface.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The air compressor cooling water pipe connection structure includes an air compressor, cooling water pipe, internal threaded sleeve, movable ring, threaded interface, second sealing ring, limit ring, positioning rod, locking rod, wedge block, L-shaped rod, first sealing ring, and spring. First, the end of the cooling water pipe is inserted into the threaded interface. Rotating the internal threaded sleeve causes it to connect threadedly to the threaded interface. The inclined surface facilitates the internal threaded sleeve pushing the locking rod. When the locking rod aligns with the locking groove, the spring pushes the locking rod and engages it in the corresponding locking groove. At this point, the internal threaded sleeve drives the first sealing ring and the air compressor... The compressor abuts against the inner wall of the internal threaded sleeve, and the limiting ring drives the second sealing ring to abut against the inner wall of the internal threaded sleeve. The locking rod and locking groove cooperate to prevent the internal threaded sleeve from loosening with the threaded interface. When the internal threaded sleeve needs to be removed from the threaded interface, push the movable ring away from the air compressor. The movable ring pushes the two locking rods to both sides through the L-shaped rod and the wedge block. When the locking rod moves to the outside of the locking groove, the internal threaded sleeve is unlocked, which can prevent the cooling water pipe connected to the air compressor from loosening, and improve the stability and reliability of the connection between the cooling water pipe and the air compressor.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution:

[0022] An air compressor cooling water pipeline connection structure includes an air compressor 1 and a cooling water pipeline 2. The side wall of the air compressor 1 is provided with a threaded interface 5. The cooling water pipeline 2 is fitted with an internal threaded sleeve 3. A limiting ring 7 is fixedly provided on the outer side wall of the cooling water pipeline 2 inside the internal threaded sleeve 3. The inner side of the internal threaded sleeve 3 is threadedly connected to the threaded interface 5. Both the upper and lower sides of the internal threaded sleeve 3 are provided with through holes. A locking rod 9 is slidably provided in the through holes. Both ends of the locking rod 9 extend to the outside of the through holes. The outer side of the threaded interface 5 is provided with a locking groove that cooperates with the locking rod 9. The end of the locking rod 9 near the threaded interface is provided with a bevel. The bevel allows the internal threaded sleeve 3 to push the locking rod 9. The rod wall of the locking rod 9 located in the through hole is provided with a reset mechanism. A movable ring 4 is slidably provided on the outer side of the internal threaded sleeve 3. A linkage mechanism is provided between the movable ring 4 and the locking rod 9.

[0023] The reset mechanism includes a positioning rod 8 and a locking rod 9. The rod wall inside the through hole has a first strip hole. The positioning rod 8 is slidably disposed in the first strip hole on the side away from the threaded interface 5. A spring 13 is fixedly provided on the rod wall of the positioning rod 8 on the side away from the threaded interface 5.

[0024] The linkage mechanism includes an L-shaped rod 11. The locking rod 9 is located on the rod wall outside the internal threaded sleeve 3 and has a second strip hole. The L-shaped rod 11 is slidably disposed inside the second strip hole. One end of the L-shaped rod 11 is fixedly connected to the movable ring 4, and the other end of the L-shaped rod 11 is fixedly provided with a wedge block 10. The locking rod 9 can be easily pushed to both sides through the wedge block 10.

[0025] The inner threaded sleeve 3 is fixedly provided with a first sealing ring 12 at the end near the air compressor 1, and the limiting ring 7 is fixedly provided with a second sealing ring 6 at the end away from the air compressor 1. The first sealing ring 12 and the second sealing ring 6 are made of corrosion-resistant rubber rings. The sealing performance between the cooling water pipe and the threaded interface is improved by the first sealing ring 12 and the second sealing ring 6, making it less prone to water leakage.

[0026] When installing the cooling water pipe 2, first insert the end of the cooling water pipe 2 into the threaded interface 5, rotate the inner threaded sleeve 3, and the inner threaded sleeve 3 is threadedly connected to the threaded interface 5. The inclined surface allows the inner threaded sleeve 3 to push the locking rod 9. When the locking rod 9 corresponds to the locking groove, the spring 13 pushes the locking rod 9 and locks it into the corresponding locking groove. At this time, the inner threaded sleeve 3 drives the first sealing ring 12 to abut against the air compressor 1, and the limiting ring 7 drives the second sealing ring 6 to abut against the inner side wall of the inner threaded sleeve 3. The locking rod 9 and the locking groove can prevent the inner threaded sleeve 3 from loosening with the threaded interface 5. When it is necessary to remove the inner threaded sleeve 3 from the threaded interface 5, push the movable ring 4 away from the air compressor 1. The movable ring 4 pushes the two locking rods 9 to both sides through the L-shaped rod 11 and the wedge block 10. When the locking rod 9 moves to the outside of the locking groove, the inner threaded sleeve 3 is unlocked, which can prevent the cooling water pipe 2 connected to the air compressor 1 from loosening with the interface, and improve the stability and reliability of the connection between the cooling water pipe 2 and the air compressor 1.
