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.

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a drain port structure for a Roots vacuum machine, including a drain port body 100, a liquid holding tank 103, a main drain pipe 101 on the lower surface of the liquid holding tank 103, a drain valve 102 at the bottom end of the main drain pipe 101, and mounting holes 104 at both the end of the drain valve 102 and the bottom edge of the main drain pipe 101. The drain port body 100 also includes:

[0025] The enhanced sealing mechanism includes a closure mounting assembly located at the connection between the drain valve 102 and the end of the main drain port 101. The end of the closure mounting assembly is located inside the main drain port 101 and has a locking mounting assembly. When the drain port body 100 is installed on the Roots vacuum machine for draining, the enhanced sealing mechanism precisely positions and reinforces the seal between the main drain port 101 and the drain valve 102, making leakage less likely during installation and use.

[0026] In order to facilitate the sealing and fixing of both the end and the surface after the closure installation assembly is installed, in this embodiment, preferably, the closure installation assembly includes a retaining ring 1011 integrally disposed on the edge of the end of the drain valve 102, and a retaining groove 1012 is provided at the bottom end of the main drain port 101. The internal structure of the retaining ring 1011 and the retaining groove 1012 are matched, so that the retaining ring 1011 can be engaged in the inside of the retaining groove 1012 to install and seal the main drain port 101 and the drain valve 102.

[0027] To facilitate enhanced sealing and fixation of the drain valve 102 and the end of the main drain port 101 through the enhanced sealing assembly, in this embodiment, preferably, the enhanced sealing assembly includes an installation groove 1013 with its inner edge located inside the main drain port 101 of the slot 1012. A sealing ring 1014 is provided inside the installation groove 1013, and the inner surface of the sealing ring 1014 is in tight contact with both the end and outer surface of the main drain port 101. When the end of the retaining ring 1011 is engaged and installed, the end of the retaining ring 1011 presses against the inner top of the sealing ring 1014, and the outer surface of the retaining ring 1011 presses against the inner surface of the sealing ring 1014, which facilitates enhanced sealing and fixation.

[0028] In order to facilitate the reinforcement of the sealing ring 1014 inside the mounting groove 1013 by means of the snap-fit ​​mounting assembly, in this embodiment, preferably, the snap-fit ​​mounting assembly includes an elastic retaining ball 1015 integrally disposed on both ends of the sealing ring 1014. Both ends of the mounting groove 1013 are provided with retaining holes 1016, and the elastic retaining ball 1015 engages with the inside of the retaining hole 1016. The elastic retaining ball 1015 can be snapped into the inside of the retaining hole 1016 to install the sealing ring 1014 inside the mounting groove 1013, which facilitates fixed installation and sealing.

[0029] The anti-detachment reinforcement mechanism includes a reinforcement component located in the middle of the mounting hole 104. Limiting sliding components are provided on both sides of the reinforcement component. A fastening adjustment component is provided at the connection between the end of the reinforcement component and the edge of the main drain port 101. When the drain port body 100 is installed on the Roots vacuum machine, the anti-detachment reinforcement mechanism reinforces the installation between the main drain port 101 and the drain valve 102. After installation, the Roots vacuum machine is less likely to loosen when it vibrates during operation, thus improving the reinforcement and fixation of the drain valve 102 at the end of the main drain port 101.

[0030] To facilitate the reinforcement and fixing of bolts using a reinforcing component, thereby strengthening the connection between the main drain port 101 and the drain valve 102, in this embodiment, preferably, the reinforcing component includes a groove 1041 located in the middle of the mounting hole 104 inside the main drain port 101. An internal thread plate 1042 is welded to one side of the groove 1041, and an adjustment groove 1044 is provided on the other side of the groove 1041. An anti-slip clamp 1043 is provided inside the adjustment groove 1044, which can connect the bolt, which is inside the groove 1041, to the surface of the internal thread plate 1042 when it is rotated and fixed. The anti-slip clamp 1043 can then be adjusted to clamp and fix the bolt to the surface for reinforcement.

[0031] In order to facilitate the stable movement and clamping of the anti-slip clamp 1043 by means of the limiting sliding assembly, in this embodiment, preferably, the limiting sliding assembly includes limiting sliding grooves 1046 formed at both ends of the adjusting groove 1044, and limiting sliders 1045 are fixed at both ends of the anti-slip clamp 1043. The limiting sliders 1045 are slidably connected to the inside of the limiting sliding grooves 1046, so that the limiting sliders 1045 can slide inside the limiting sliding grooves 1046 when the anti-slip clamp 1043 moves, which facilitates the stable control of the anti-slip clamp 1043.

[0032] To facilitate the adjustment and reinforcement of the anti-slip clamp 1043 via the fastening adjustment assembly, in this embodiment, preferably, the fastening adjustment assembly includes a threaded rod 1048 penetrating the edge of the main drain port 101, and the end of the threaded rod 1048 is fixed to the end of the anti-slip clamp 1043 by welding. The end of the threaded rod 1048 is threaded with a fastening nut 1047 on the surface of the main drain port 101. A wrench can be engaged on the outer surface of the fastening nut 1047 to drive the fastening nut 1047 to rotate in place at the end of the threaded rod 1048, and during the rotation in place, the threaded rod 1048 and the anti-slip clamp 1043 move until the anti-slip clamp 1043 is clamped and fixed to the surface of the bolt for reinforcement.

[0033] The working principle and usage process of this utility model: Before use, the drain port structure of this Roots vacuum machine is first installed. The sealing ring 1014 is squeezed and deformed to close inside the mounting groove 1013. At the same time, the elastic retaining ball 1015 is engaged inside the retaining hole 1016, so that the sealing ring 1014 is completely installed inside the mounting groove 1013. When installing the drain valve 102, the retaining ring 1011 at the end of the drain valve 102 is engaged inside the retaining groove 1012. After installation between the main drain port 101 and the drain valve 102, the end of the retaining ring 1011 is squeezed against the inner top of the sealing ring 1014 after fixing. The outer surface of the retaining ring 1011 is pressed against the inner edge of the sealing ring 1014. During installation, the end and surface of the retaining ring 1011 are tightly pressed to strengthen the seal. At the same time, the sealing ring 1014 is easily and accurately installed and does not easily shift, thereby improving the sealing performance of the drain valve 102 installed at the end of the main drain port 101.

[0034] Then, after the main drain pipe port 101 and the drain valve 102 are sealed and closed, the bolt is fixedly installed inside the mounting hole 104. When the bolt rotates inside the mounting hole 104, it is threadedly connected to the outer surface of the internal thread plate 1042 inside the tank 1041. The wrench is then engaged on the outer surface of the fastening nut 1047, causing the fastening nut 1047 to rotate on the outer surface of the threaded rod 1048. The fastening nut 1047 is rotated in place until the threaded rod 1048 moves. When the threaded rod 1048 moves, it drives... The anti-slip clamp 1043 moves inside the adjusting groove 1044. When the anti-slip clamp 1043 moves, it drives the limiting slider 1045 to slide within the limiting groove 1046, thereby stably moving and clamping the anti-slip clamp 1043 to the other side of the bolt, which facilitates the bolt to be reinforced and fixed. This strengthens the fixation between the main drain port 101 and the drain valve 102, making it less likely to loosen when the Roots vacuum machine vibrates after installation, and improving the reinforcement and fixation of the drain valve 102 at the end of the main drain port 101.
