Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to an engine oil alarm. Background Art
[0002] Engine oil is used for lubrication in the transmission mechanical components of a car. Lubrication can reduce the wear between the mechanical components. The oil tank is filled with lubricating oil, which is transported to various systems for lubrication. After use, the oil in the oil tank will sound an alarm through the oil alarm to notify personnel to add oil. Generally, the oil alarm detects the oil pressure in the oil tank by pressure, thereby detecting the oil capacity in the oil tank.
[0003] The oil alarm has high requirements for sensitivity, durability and stability. It needs to be able to respond promptly and trigger stably during use. Existing alarms mostly use contact triggers to connect circuits to sound alarms. Their contact structures are easily damaged and involve circuit design, making the structure more complex and less easy to use.

[0013] (III) Beneficial effects
[0014] After adopting the above technical scheme, the utility model has the following advantages compared with the prior art: the utility model is an oil alarm, which pushes the diaphragm push rod under a certain oil pressure, and the push rod overcomes the spring force to make the blue vertical groove cover the red column, indicating that the oil pressure meets the oil splash lubrication requirement, and when the push rod is pushed, the push rod is slidably connected with the clamping ring and the fixing ring, and can slide vertically stably. If the blue push rod part is covered smoothly without obvious shaking, it indicates that the oil pump pressure is stable. When shutting down, in the state of losing oil pressure, the push rod rebounds quickly to expose the red column, which is easy to observe, and the structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 This is a schematic diagram of the structure of the utility model (the spring is not shown);
[0017] In the figure: 1 base, 2 shell, 21 fixing ring, 3 transparent shell, 4 oil channel, 5 diaphragm, 51 protrusion, 6 push rod, 61 limit ring, 7 vertical groove, 8 column, 9 clamping ring, 10 notch, 11 spring. DETAILED DESCRIPTION
[0018] The utility model is further described in detail below through the drawings and embodiments.
[0019] The utility model provides an oil alarm, such as Figure 1-2 As shown, it includes a base 1, a shell 2 is provided on the base 1, a transparent shell 3 is provided on the shell 2, an oil channel 4 is provided in the base 1, a cavity is formed inside the base 1 and the shell 2, a diaphragm 5 is provided at the bottom of the cavity, the diaphragm 5 is connected to the oil channel 4, a push rod 6 is provided above the diaphragm 5, a vertical groove 7 is provided on the top of the push rod 6, and a column 8 is provided on the bottom surface of the transparent shell 3, and the diameter of the column 8 is smaller than the diameter of the vertical groove 7.
[0020] Under a certain oil pressure, the diaphragm 5 is pushed, and the diaphragm 5 lifts the push rod 6. The push rod 6 overcomes the elastic force of the spring 11 to make the blue vertical groove 7 cover the red column 8, indicating that the oil pressure meets the oil splash lubrication requirement. When the push rod 6 is pushed, the push rod 6 is slidably connected with the clamping ring 9 and the fixing ring 21, and can slide vertically stably. If the blue push rod 6 is partially covered smoothly without obvious shaking, it indicates that the oil pump pressure is stable. When shutting down, in the state of losing oil pressure, the push rod 6 rebounds quickly to expose the red column 8, which is easy to observe. The structure is simple and easy to use.
[0021] A clamping ring 9 is provided in the cavity, and the clamping ring 9 is arranged on the diaphragm 5. A downward protrusion 51 is provided on the outer side of the diaphragm 5. A notch 10 is provided on the base 1. The outer side of the clamping ring 9 presses the outer side of the diaphragm 5 against the base 1 so that the protrusion 51 is embedded in the notch 10, effectively preventing the engine oil from entering the cavity.
[0022] Reference Figure 2 The push rod 6 passes through the clamping ring 9 and is slidably connected to the inner ring of the clamping ring 9. A limit ring is provided on the push rod 6 to prevent the spring 11 from pushing the push rod 6 against the diaphragm 5 when there is no oil pressure, thereby causing the diaphragm 5 to lose its function.
[0023] A fixing ring 21 is provided inside the outer shell 2, and the push rod 6 passes through the fixing ring 21 and is slidably connected to the inner ring of the fixing ring 21. A spring 11 is sleeved on the push rod 6, one end of the spring 11 is fixed on the limiting ring 61, and the other end is fixed to the lower end of the fixing ring 21. The upper end of the fixing ring 21 is fixedly connected to the transparent shell 3.
[0024] The top of the push rod 6 is bright blue, and the lower end of the column 8 is bright blue. This arrangement makes the visual effect more obvious and easier to observe.
