Description

Technical Field

[0001] This utility model relates to the field of maintenance technology for chemical production equipment, and in particular to a lubricating oil filling structure that facilitates observation of liquid level. Background Technology

[0002] In the maintenance of chemical production equipment, such as in the processing environment of ferrous sulfate, dust and corrosive substances often corrode the motor's observation window and cause foreign matter to adhere to it. This makes it difficult for workers to clearly observe the lubricating oil level, thus affecting their timely judgment on whether lubricating oil needs to be added. At the same time, the limited space around the motor's filler hole makes it inconvenient to add lubricating fluid using tools, increasing the difficulty of maintenance and operational risks. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that hinder timely judgment of whether lubricating oil needs to be added, and to propose a lubricating oil filling structure that facilitates observation of the liquid level.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lubricating oil filling structure that facilitates observation of the liquid level includes an L-shaped filling pipe, one end of which is connected to the filling hole of the motor.

[0006] An observation box is fixed to and connected to the side wall of the vertical section of the refueling pipe, and an observation window is installed on the side of the observation box.

[0007] A protective panel is slidably installed on the outside of the observation window of the observation box, and a cleaning cloth is fixed to the inside of the protective panel;

[0008] The fuel cap is fitted onto the annular groove on the outer wall of the top of the fuel filler pipe;

[0009] The threaded ring engages with the threaded groove on the outer wall of the refueling pipe and the oil cap.

[0010] In one possible design, the top and bottom of the observation box are fixedly connected to a sliding shell, and the top and bottom of the protective plate are fixed with a sliding frame, with one end of the sliding frame slidably disposed inside the sliding shell.

[0011] In one possible design, the cleaning cloth is fixed to the inner wall of the protective panel facing the observation window.

[0012] In one possible design, a slip ring is slidably fitted on the outer wall of the threaded ring, a through hole is provided on the top of the upper sliding shell, and a slot is provided on the top of the upper sliding frame, with the slip ring passing through the through hole and engaging with the slot.

[0013] In one possible design, the outer wall of the slip ring is provided with anti-slip texture.

[0014] In one possible design, a limiting groove is formed on the outer wall of the annular groove, and a limiting strip that cooperates with the limiting groove is fixed to the inner wall of the oil cap.

[0015] In one possible design, the vertical section of the refueling pipe is welded to the observation box.

[0016] In this application, during actual use, the slip ring is slid upwards to disengage it from the slot, thus releasing the limiting state of the sliding bracket. The guard plate is then slid to one side to allow the operator to observe the lubricating oil level through the observation window. When the guard plate is slid open or closed, the cleaning cloth on its side wall will wipe the surface of the observation window. When lubricant needs to be added, simply rotate the outer slip ring to rotate the threaded ring. The threaded ring will move downwards and, once it disengages from the threaded groove on the oil cap surface, its fixed state will be released. After that, it can be removed to add lubricant.

[0017] In this utility model, the lubricating oil filling structure that facilitates observation of the liquid level, through the external filling pipe and corresponding observation window, can both facilitate observation of the lubricating fluid level and facilitate the use of tools by the staff to perform the filling operation.

[0018] In this utility model, the lubricating oil filling structure that facilitates observation of the liquid level can be covered and protected during daily use by a protective plate and a cleaning cloth, thereby avoiding pollution of the surrounding environment, making it convenient for staff to check the lubricating fluid level, and also allowing for cleaning when opening and closing.

[0019] In this invention, the external observation window can be covered and protected during use to ensure clarity during observation. It can also be cleaned after each inspection to reduce environmental contamination of the observation window during the inspection period. At the same time, the external refueling pipe has a large operating space, which facilitates the refueling operation for the staff. Attached Figure Description

A tempered glass observation window 7 is embedded on one side of the observation box 3 for observing the lubricating oil level inside the pipe. Sliding shells 6 are fixed to the top and bottom of the observation box 3. A protective plate 4 slides against the sliding shells 6 via sliding brackets 16 at the top and bottom. The end of the sliding bracket 16 inserts into the inner cavity of the sliding shell 6 and slides. A cleaning cloth 12 is adhered to the inner wall of the protective plate 4. When the protective plate 4 slides, the cleaning cloth 12 contacts the surface of the observation window 7 for wiping.

[0028] An annular groove 9 is provided at the top of the vertical section of the refueling pipe 2, and the oil cap 5 is fitted onto its outer wall. Continuous threaded grooves 8 are provided at corresponding positions on the outer wall of the refueling pipe 2 and the outer wall of the oil cap 5.
