Description

Technical Field

[0001] The utility model belongs to the technical field of oil level display, and in particular relates to an oil level display. Background Art

[0002] The oil level indicator is a very commonly used accessory in mechanical operation equipment. It is an essential accessory for equipment that needs to be lubricated with engine oil, such as reducers lubricated with thin oil, bearing boxes lubricated with thin oil, etc. At present, the oil level indicators widely used in the market basically adopt a perspective oil mark display. The oil mark using this method is easy to install, the liquid level display is intuitive, and the oil level is installed on the box body, basically flush with the plane of the box body, and will not affect the surrounding parts of the box body. The first defect is that since the oil mark indicator is installed on the box body with threads, the low and high oil level scales displayed by the oil mark indicator are easy to deflect, and it is necessary to rely on adding and subtracting shims to adjust to ensure the correct position of the oil level scale. Second, since the lubricating oil generally moves with the lubricating parts when the equipment is running, the oil level fluctuates greatly, which directly affects the position accuracy of the indicator. Third, the oil mark indicator is made of transparent materials, and the lubricating oil is also a transparent liquid. The contrast of the liquid level display is not obvious, which is easy to cause misjudgment and cause equipment operation accidents. Summary of the invention

[0003] In order to solve the above problems existing in the prior art, the utility model provides an oil level display with good sealing effect and obvious and accurate liquid level display.

[0004] The technical solution adopted by the utility model is:

[0005] The oil level indicator comprises a body, the inner end face of the body is connected to the box, the outer end face of the body is provided with an observation mirror, the surface of the observation mirror is provided with a scale, a floating ball is installed in the window, and a stabilizing grid for stabilizing the liquid level is installed in the body. The utility model prevents the lubricating oil from fluctuating at the window with the operation of the equipment through the stabilizing grid structure, thereby ensuring the accuracy of observation.

[0006] Furthermore, the stabilizing grid includes a first filter screen and a second filter screen, the first filter screen cover is arranged outside the second filter screen, and a filler is arranged between the end faces of the first filter screen and the second filter screen. The utility model stabilizes the fluctuating oil level through the action of the two filter screens and the blocking action of the internal filler, thereby reducing the fluctuation of the oil level and facilitating the accurate determination of the oil level.

[0007] Furthermore, the first filter screen is made of a 60-mesh stainless steel filter screen.

[0008] Furthermore, the second filter screen is made of a 120-mesh stainless steel filter screen.

In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, the meaning of "multiple" is two or more, unless otherwise clearly defined.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] See also Figure 1-7This embodiment provides an oil level indicator, including a body 4, the inner end surface of the body 4 is connected to the box, the outer end surface of the body 4 is installed with an observation mirror 2, the surface of the observation mirror 2 is provided with a scale 21, a float 1 is installed in the window, and a stabilizing grid 7 for stabilizing the liquid level is installed in the body 4. The utility model prevents the lubricating oil from fluctuating at the window with the operation of the equipment through the stabilizing grid structure, thereby ensuring the accuracy of observation.

[0029] The stabilizing fence 7 of this embodiment includes a first filter screen 71 and a second filter screen 73. The first filter screen 71 is covered outside the second filter screen 73, and a filler 72 is arranged between the end faces of the first filter screen 71 and the second filter screen 73. The utility model stabilizes the fluctuating oil level through the action of the two filters and the blocking action of the internal filler, thereby reducing the fluctuation of the oil level and facilitating the accurate determination of the oil level. The first filter screen 71 is made of a 60-mesh stainless steel filter screen. The second filter screen 73 is made of a 120-mesh stainless steel filter screen. The filler 72 is a winding stainless steel sheet or steel wire. A connector 74 is provided on the stabilizing fence 7, and a connecting port 41 is provided on the standard body 4. The stabilizing fence 7 and the standard body 4 are fixed to rotate relative to the connecting port 41 through the connector 74. Specifically, the connector 74 is a stepped cylindrical structure, including a large cylinder and a small cylinder. One end of the connection port 41 is a large circular hole, which is connected to a slideway. The inner side of the slideway is fixed with the large cylinder, and the small cylinder can slide along the slideway. The stabilizing grid structure of this embodiment is an integrated structure. The wear impurities generated by the operation of the equipment must be filtered by the filter before entering the window mirror, which can prevent the contamination of the window mirror. When in use, you only need to take out the structure to clean it. At the same time, the outer end surface of the stabilizing grid 7 can fix the float 1 in the space of the observation mirror 2.

[0030] In this embodiment, a sealing ring 6 is provided between the end face of the mark body 4 and the observation mirror 2. The sealing ring 6 can be an O-ring or a flat gasket. The observation mirror 2 is pressed onto the outer end face of the mark body 4 through the connector 3 and the sealing ring 6 is pressed. A sealing gasket 5 is provided between the inner end face of the mark body 4 and the housing. Specifically, in this embodiment, the mark body 4 is installed on a device such as a bearing box or a reduction box that needs to display the oil level by means of a threaded connection, wherein the housing and the oil level display are sealed by the gasket 5 to prevent oil leakage. An O-ring is used to seal between the observation mirror 2 and the mark body 4 to prevent lubricating oil leakage.

[0031] The surface of the float 1 described in this embodiment is provided with a luminous coating, and the coating can be a striking red or yellow color, so that the oil level is eye-catching and clear.

[0032] The oil level display mark adjustment method of the utility model is as follows:

[0033] The three parts of the observation mirror 2, the connector 3, and the mark body 4 are connected by the connector 3 and the mark body 4. The observation mirror 2 is sealed and positioned. The connection between the connector 3 and the mark body 4 can be loosened to conveniently adjust the high and low oil level marks on the observation mirror 2. After adjustment, keep the parts of the observation mirror 2 still and tighten the connector 3 and the mark body 4. This method can easily ensure the correct position of the oil level mark. The surface of the observation mirror 2 has obvious high and low oil level scale marks. A float 1 is installed in the window. The float 1 can float dynamically with the height of the oil level. The scale 21 on the outer surface and the float 1 floating on the oil inside reflect the oil level. At the same time, the surface of the float 1 adopts a luminous eye-catching red or yellow color to make the oil level eye-catching and clear.

[0034] The utility model has good sealing effect and obvious and accurate liquid level display.
