[0033] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] The embodiment of the present application provides a quick-insert drain valve, which can solve the problem in the related art that the fiber-wound air storage cylinder cannot position the end of the drain pipe exactly at the bottom end of the air storage cylinder.

[0035] The air intake drying equipment of existing vehicle air cylinders cannot completely dehumidify, causing water to accumulate inside the air cylinder after long-term operation, affecting the work efficiency of parts and safety in winter use. Therefore, regular drainage is required.

[0036] Due to gravity flow, existing air cylinders require the drain valve to be located at the very bottom of the cylinder. However, placing the drain valve connector at the bottom of a fiber-wound air cylinder would interfere with the outer winding path, forcing the winding to proceed radially. This would prevent the winding of the end caps on both sides from being completed, resulting in poor end cap strength and a weak connection between the end caps and the cylinder.

[0037] Therefore, regarding the fiber-wound air storage cylinder, its drain valve cannot be arranged at the bottom of the cylinder body. If the drain valve is arranged on the side and the water is discharged through the drain pipe in the form of pressure difference, the problem of how to position the end of the drain pipe exactly at the bottom of the air storage cylinder is still not solved, and the drain function of the fiber-wound air storage cylinder cannot be effectively guaranteed. Figures 1 to 4 The embodiment of the present application provides a quick-insert drain valve, which includes: a rotating body 1, a docking piece and a drain pipe 5, one end of the rotating body 1 is used to communicate with the drain valve port of the air storage cylinder; the docking piece is rotatably connected to the other end of the rotating body 1; one end of the drain pipe 5 is connected to the docking piece, and the other end passes through the middle of the rotating body 1 and extends into the interior of the air storage cylinder.

[0038] In this application, the rotating body 1 is connected to the drain valve port of the air cylinder. After the docking piece is connected to the rotating body 1, the drain pipe 5 can pass through the rotating body 1 and extend into the interior of the air cylinder. Since the docking piece and the rotating body 1 are rotatably connected, rotating the docking piece can adjust the position of the end of the drain pipe 5, thereby ensuring that the end of the drain pipe 5 is positioned at the bottom end of the interior of the air cylinder.

[0039] On the basis of the above embodiment, in this embodiment, the docking member includes: a quick-connect body 2 , an elastic member 3 and a drain valve body 4 .

[0040] Specifically, the quick-plug body 2 is rotatably connected to the other end of the rotating body 1; wherein, the material used for the quick-plug body 2 is one or more of nylon, polypropylene and their modified materials, and the molding process is injection molding or 3D printing. Preferably, the material used for the quick-plug body 2 is nylon and glass fiber material, and the molding process is injection molding.

[0041] A groove body 23 and a second through hole 25 are provided inside the quick-connect body 2, and the second through hole 25 is connected to the groove body 23 and the drain pipe 5; the elastic member 3 is arranged inside the groove body 23; the drain valve body 4 is arranged on one side of the elastic member 3 and is used to block the opening side of the groove body 23.

[0042] Specifically, the quick-connect body 2 includes: a shell 26 and a bamboo joint 21, the groove body 23 and the second through hole 25 are opened inside the shell 26, and the rotating body 1 is rotatably connected to the shell 26; the bamboo joint 21 is arranged on the side of the shell 26 away from the groove body 23, and is connected to the inside of the groove body 23 through the second through hole 25, and one end of the drain pipe 5 is connected to the bamboo joint 21.

[0043] In this embodiment, a recessed body 23 is defined at one end of the housing 26 to accommodate the elastic member 3. In this embodiment, the elastic member 3 can be a spring, one end of which is secured to the inner wall of the recessed body 23 and the other end of which is connected to the drain valve body 4. A receiving groove is also defined on the side of the housing 26 of the quick-connect body 2, away from the recessed body 23. One end of the bamboo joint 21 is disposed within the receiving groove. A water passage cavity is defined in the middle of the bamboo joint 21 along its length. Since a second through hole 25 is also defined within the housing 26 for drainage, the bamboo joint 21 can be connected to the interior of the recessed body 23 via the second through hole 25.

[0044] Furthermore, in this embodiment, the diameter of the inscribed circle of the cross-section of the accommodating groove is set to be larger than the diameter of the bamboo joint 21, so that a rotating body accommodating cavity is formed between the outer circumferential surface of the bamboo joint 21 and the inner wall of the accommodating groove. One end of the rotating body 1 is connected to the drain valve port of the air reservoir; the other end is placed inside the rotating body accommodating cavity. The rotating body 1 is provided with a first through hole 14. Therefore, when the rotating body 1 is sleeved onto the outer circumferential surface of the bamboo joint 21 through the first through hole 14, it is rotated and connected to the interior of the rotating body 1 accommodating cavity.

[0045] It should be noted that, since the drain pipe 5 is also sleeved on the outer surface of the bamboo joint 21, the bamboo joint 21 can be installed with the drain pipe 5 by interference fitting to prevent it from getting loose. When the rotating body 1 is sleeved on the outer surface of the bamboo joint 21, there is also a gap between the inner wall of the rotating body 1 and the outer surface of the bamboo joint 21, which can accommodate the installation of the drain pipe 5. One end of the rotating body 1 connected to the drain valve port of the air storage cylinder is provided with a mounting thread 11, so the rotating body 1 is threadedly connected to the drain valve port of the air storage cylinder; when the quick-insert body 2 and the rotating body 1 rotate relative to each other, the rotating body 1 is fixed and the quick-insert body 2 rotates. In order to ensure that the quick-insert body 2 rotates more smoothly, in some embodiments, when the surface of the drain pipe 5 fits the inner wall of the rotating body 1, the surface of the drain pipe 5 is provided with a rotational connection with the inner wall of the rotating body 1; in other embodiments, a gap can also be provided between the surface of the drain pipe 5 and the inner wall of the rotating body 1 to avoid interference between the drain pipe 5 and the rotating body 1 when the quick-insert body 2 rotates.

[0046] Furthermore, a second locking step 22 is provided on the inner wall of the receiving groove, and a first locking step 12 is provided on the surface of the rotating body 1. When the quick-connect drain valve is in use, the first locking step 12 engages with the second locking step 22. This arrangement ensures that when the rotating body 1 and the housing 26 rotate, the first locking step 12 and the second locking step 22 cooperate to prevent the rotating body 1 from being separated from the interior of the housing 26. In this installed state, the rotating body 1 and the quick-connect body 2 can rotate freely and adjust the angle.

[0047] In some embodiments, the first locking step 12 is configured as a raised structure fixed to the surface of the rotating body 1, and the second locking step 22 is configured as a recessed structure recessed into the inner wall of the receiving groove. The second locking step 22 is buckled onto the first locking step 12 by interference fit to complete the fastening installation. Therefore, when the raised structure is located inside the recessed structure, the rotating body 1 can be prevented from being separated from the interior of the housing 26.

[0048] In other embodiments, the first locking step 12 is configured as a circle of recessed structure recessed in the surface of the rotating body 1, and the second locking step 22 is configured as a protruding structure fixed to the inner wall of the accommodating groove. When the protruding structure is located inside the recessed structure, it can prevent the rotating body 1 from detaching from the inside of the shell 26.

[0049] It should be noted that there are various ways to configure the first locking step 12 and the second locking step 22 , which will not be described one by one here.

[0050] Furthermore, to prevent the quick-discharge valve from leaking, a seal 13 is sleeved on the surface of the rotating body 1. When the quick-discharge valve is in use, the seal 13 abuts against the inner wall of the receiving groove. In this embodiment, the seal 13 can be a sealing ring or a sealing gasket. The seal 13 can be selected according to actual needs and is not limited by this application.

[0051] On the basis of the above embodiment, in this embodiment, the drain valve body 4 includes a blocking plate 45 . The blocking plate 45 is located on one side of the elastic member 3 and is used to block the opening of the groove body 23 .

[0052] In some possible embodiments, one end of the spring is fixed to the groove body 23, and the other end is fixed to the sealing plate 45; the size of the sealing plate 45 is larger than the opening size of the groove body 23, and when the spring is compressed, the sealing plate 45 can block the opening of the groove body 23; when the spring is extended, a gap appears between the sealing plate 45 and the opening of the groove body 23, which can be used for drainage.

[0053] In other possible embodiments, a cover plate 24 is fixedly attached to one side of the quick-connect body 2, i.e., the housing 26, at the opening of the recessed body 23. The cover plate 24 is connected to the housing 26 by welding, screwing, or other means. A connecting hole is defined in the cover plate 24, and a blocking plate 45 is positioned within the recessed body 23. A protruding structure 43 is provided on one side of the blocking plate 45, with one end of the protruding structure 43 extending through the connecting hole and extending to the exterior of the recessed body 23. In this embodiment, the connecting rod in the protruding structure is cylindrical and fixed to the blocking plate 45. The connecting rod has a length greater than the thickness of the cover plate 24 and a diameter less than the diameter of the connecting hole. When the spring is installed and compressed, it supports the blocking plate 45, causing it to block the connecting hole and maintain the drain valve body 4 closed by its rebound force. When the protruding structure 43 is pressed toward the housing 26, the spring is further compressed, causing the blocking plate 45 to move away from the cover plate 24, opening the connecting hole.

[0054] Furthermore, in this embodiment, a groove structure 41 is provided on the side of the sealing plate 45 close to the cover plate 24, and a sealing ring 42 is provided inside the groove structure 41; by providing the sealing ring 42, the gap between the sealing plate 45 and the cover plate 24 can be sealed.

[0055] In addition, a pull ring 44 is provided at one end of the protruding structure 43. Specifically, a circular hole is provided in the middle of the protruding structure 43, and the pull ring 44 can be installed in the circular hole.

[0056] In this embodiment, the manufacturing and installation process of the quick-insert drain valve is as follows:

[0057] The rotating body 1 and the drain valve body 4 are formed by machining. The material of the rotating body 1 and the drain valve body 4 can be copper alloy. Then, the seal 13 is assembled on the rotating body 1, and the sealing ring 42 is assembled on the blocking plate 45. The pull ring 44 is configured as a steel wire curled into a key ring shape. The quick-connect body 2 and the cover plate 24 are respectively injection molded, and the material is nylon 12 + 50% glass fiber.

[0058] During installation, place the spring inside the groove body 23, install the drain valve body 4 on the top, pass the cover plate 24 through the raised structure 43, compress the spring until the cover plate 24 contacts the shell 26, and then connect the cover plate 24 and the shell 26 by laser welding; then pass the pull ring 44 through the raised structure 43, and press the drain pipe 5 through the bamboo joint 21; then install the rotating body 1 on the drain valve port on one side of the air storage cylinder through the installation thread 11; finally, press the above-mentioned docking piece and drain pipe 5 onto the rotating body 1; then rotate the quick-connect body 2 to adjust the end of the drain pipe 5 to the bottom of the air storage cylinder.

[0059] In summary, the present application realizes the free rotation angle of the drain valve, and can quickly install the rotating body 1 and the docking body through the interference fit of the first locking step 12 and the second locking step 22; it solves the technical difficulties of drainage from the side of the air storage cylinder.
