Description

Technical Field

[0001] This utility model relates to the field of material inlet sealing technology, specifically a splash-proof liquid filling port. Background Technology

[0002] The machine's water tank needs to be replenished with liquid. The existing liquid inlet is more suitable for adding liquid when the machine is stopped. When the machine is running, the liquid inlet does not have a splash protection function, which poses a great danger to the liquid adding personnel. Therefore, there is a need for a device that can prevent the liquid inlet from splashing during liquid adding, so that liquid can be added while the machine is running, ensuring the safety of the personnel when adding liquid while ensuring the operation of the machine. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a splash-proof liquid filling port, which solves the problem of preventing splashing during liquid filling, facilitating liquid filling while the machine is running continuously, and ensuring the safety of workers when performing liquid filling operations while ensuring machine operation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a splash-proof liquid filling port, comprising a filling tube, wherein an anti-splashing device is welded inside the filling tube;

[0005] The anti-splash device includes an upper plate, a middle plate, and a lower plate, which are fixedly connected. One end of the upper plate and the lower plate are welded to the inner wall of the liquid filling pipe. The included angle between the upper plate, the middle plate, and the lower plate is less than 90°. Square holes are opened on one side of the upper plate and the middle plate. The upper plate and the middle plate have staggered holes. Multiple round holes are opened on one side of the lower plate.

[0006] Preferably, one end of the liquid filling tube is provided with a threaded cap extending into it, and the inner wall of the liquid filling tube is provided with an internal thread groove that matches the threaded cap.

[0007] Preferably, the end of the liquid filling tube near the threaded cap has an annular groove, and a sealing ring extending to the outside of the annular groove is provided inside the annular groove.

[0008] Preferably, a limiter is provided on one side of the threaded cap, and a steel wire rope is fixedly connected to one side of the limiter. One end of the steel wire rope is installed on the threaded cap through an interference fit between the limiter and the threaded cap.

[0009] Preferably, a stainless steel ring is fixedly connected to one end of the liquid filling tube near the threaded cap, and the end of the wire rope away from the limiter is fixedly connected to the stainless steel ring.

[0010] Preferably, a semi-circular groove is provided on the side of the stainless steel ring away from the liquid filling pipe, a winding rod is rotatably connected between the two sides of the inner wall of the semi-circular groove, a torsion spring is fixedly connected between the winding rod and the inner wall of the semi-circular groove, and the end of the wire rope away from the limiter is fixedly connected to the winding rod.

[0011] Compared with the prior art, the present invention provides a splash-proof liquid filling port, which has the following beneficial effects:

[0012] 1. The anti-splash component prevents water from splashing up from inside the water tank, making it easy to add liquid while the machine is running continuously. This ensures the machine's operation while also protecting the safety of staff when adding liquid.

[0013] 2. By setting staggered openings in the upper and middle layers, the overlapping area is reduced, thereby reducing the area where liquid can splash out. This also ensures that the liquid filling flow rate meets the requirements when adding liquid. The third layer adopts a mesh design, which can not only meet the liquid filling flow rate requirements but also greatly reduce the liquid splashing out from inside the water tank.

[0014] 3. The filling pipe and the threaded cap are connected by a steel wire rope, which can prevent the threaded cap from being lost and also prevent it from being placed randomly, causing the threaded cap to come into contact with contaminants and contaminate the liquid in the water tank.

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Example

[0022] Figures 1-3 As an embodiment of this utility model, a splash-proof liquid filling port includes a filling pipe 1, and an anti-splash device 2 is welded inside the filling pipe 1. When the machine is running continuously, the operator adds water into the water tank from the top of the filling pipe 1. The anti-splash device blocks the water splashed up from inside the water tank, ensuring the operation of the machine while protecting the safety of the operator when adding liquid.

[0023] The anti-splash device 2 includes an upper plate 21, a middle plate 22, and a lower plate 23. The upper plate 21, the middle plate 22, and the lower plate 23 are fixedly connected. One end of the upper plate 21 and the lower plate 23 are welded to the inner wall of the liquid filling pipe 1. The included angle between the upper plate 21, the middle plate 22, and the lower plate 23 is less than 90°. Square holes are opened on one side of the upper plate 21 and the middle plate 22. The upper plate 21 and the middle plate 22 have staggered openings. Multiple round holes are opened on one side of the lower plate 23. The upper and lower ends of the anti-splash device are fixed to the inside of the liquid filling pipe 1 by welding. Because the upper plate 21 and the middle plate 22 have staggered openings, the overlapping area is reduced, thereby reducing the area where the liquid can splash out. It can also ensure that the liquid filling flow rate meets the requirements when adding liquid. The third layer adopts a mesh design, which can not only meet the liquid filling flow rate requirements but also greatly reduce the liquid splashing out from the inside of the water tank.

[0024] One end of the filling tube 1 is provided with a threaded cap 3 extending into it. The inner wall of the filling tube 1 has an internal thread groove that matches the threaded cap 3. The end of the filling tube 1 near the threaded cap 3 has an annular groove. Inside the annular groove is a sealing ring 4 extending to the outside. A limiter 5 is provided on one side of the threaded cap 3, penetrating the threaded cap 3. A steel wire rope 6 is fixedly connected to one side of the limiter 5. A stainless steel ring 7 is fixedly connected to the end of the filling tube 1 near the threaded cap 3. The end of the steel wire rope 6 away from the limiter 5 is fixedly connected to the stainless steel ring 7. The threaded connection between the threaded cap 3 and the filling tube 1 enhances the shock resistance. During installation, the threaded cap 3 rotates continuously into the filling tube 1, squeezing and deforming the sealing ring 4 extending to the outside of the filling tube 1, increasing the sealing degree at the connection between the threaded cap 3 and the filling tube 1. The filling tube 1 and the threaded cap 3 are connected by the steel wire rope 6, which can prevent the threaded cap 3 from being lost and prevent it from being contaminated by pollutants due to improper placement.

[0025] A semi-circular groove is provided on the side of the stainless steel ring 7 away from the liquid filling pipe 1. A winding rod 8 is rotatably connected between the two sides of the inner wall of the semi-circular groove. A torsion spring 9 is fixedly connected between the winding rod 8 and the inner wall of the semi-circular groove. The end of the steel wire rope 6 away from the limiter 5 is fixedly connected to the winding rod 8. When there is no place to place the threaded cap 3 next to the liquid filling pipe 1, and the threaded cap 3 needs to be moved to a position far away from the liquid filling pipe 1, the worker pulls the threaded cap 3 to move it away from the liquid filling pipe 1. The threaded cap 3 pulls the steel wire rope 6 to disengage from the winding rod 8. The steel wire rope 6 pulls the winding rod 8 to rotate, which in turn drives the torsion spring 9 to twist and deform until the threaded cap 3 is stuck at a position far away from the liquid filling pipe 1. When it is necessary to reinstall the threaded cap 3 onto the liquid filling pipe 1, the threaded cap 3 is moved closer to the liquid filling pipe 1. Due to its own elasticity, the torsion spring 9 drives the winding rod 8 to rotate, and the steel wire rope 6 is rewound onto the winding rod 8, increasing the range of movement of the threaded cap 3.
