Abstract

The utility model discloses a mechanical oil tank refuels structure. The device is arranged on the side surface of the oil tank, and the center of the device is as high as lubricating oil. The oil level in the oil tank can be conveniently seen from the sight glass of the oiling device, and the device is very simple and practical.

Description

Mechanical oil tank refuels structure

Technical Field

The utility model relates to an oiling device of mechanical equipment oil tank, specific device that refuels and can survey the oil level in to the oil tank that says so belongs to mechanical technical field.

Background

The conventional oil tank view mirror and oil filling port design is shown in fig. 4, two threaded holes are formed in an oil tank, a screw plug 11 is installed in one threaded hole, and after the screw plug 11 is detached, an additional oil filling funnel is used for filling oil into the oil tank. The other threaded hole mounting sight glass 12 observes the oil level state in the oil tank. Although the oil filling funnel is additionally used for filling oil, the oil filling process is not convenient because the oil filling hole is positioned on the vertical plane.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide an oil tank refuels structure, only need open a screw hole on the oil tank, can conveniently refuel after installing this structure to conveniently look over the oil level of oil tank simultaneously.

The utility model discloses a solve above-mentioned technical problem and adopt following technical scheme:

a mechanical oil tank oiling structure is arranged in a threaded hole pre-opened on the side edge of an oil tank and comprises a threaded sleeve screwed in the threaded hole and an oil inlet pipe assembled in an inner cavity of the threaded sleeve in a sliding manner, wherein one end of the oil inlet pipe is opened, the other end of the oil inlet pipe is closed, and an oil inlet is formed in the pipe wall of the oil inlet pipe close to the closed end; the shape of the outer side of the tube body of the oil inlet tube is basically consistent with the shape of the inner side of the tube cavity of the threaded sleeve. When needing to refuel, take out the oil pipe from the thread bush, can expose the oil filler hole and accomplish and refuel, this hydraulic fluid port is vertical moreover, for the lateral part opening before, does not worry the problem of oil leak. And can also direct observation oil level through vertical oil inlet, it is very convenient.

The utility model discloses the technical scheme who further injects does:

further, the pipe body slides into the threaded sleeve until the oil inlet completely enters the threaded sleeve to form a closed state, and the pipe body slides out of the threaded sleeve until the oil inlet completely exposes out of the threaded sleeve to form an open oiling state. The plug is sealed when being plugged in, and the oil can be added or the oil level can be observed when the plug is pulled out, so that the plug is very convenient.

Furthermore, 3 grooves are formed in the outer side of the pipe body, two grooves are sealing grooves with built-in sealing rings, the other groove is a blocking groove with built-in blocking rings, and the two sealing grooves are assembled on two sides of the oil inlet and are used for preventing oil leakage in a closed state. The retaining groove is arranged on the oil outlet side of the oil inlet pipe, the retaining ring is higher than the outer side of the pipe body, and forms a limiting part with the end part of the threaded sleeve when the retaining ring runs to a preset station, so that the embarrassment that the retaining ring limits the moving distance and prevents the pull-out excessive oil pipe from falling is realized.

Further, an oil level indicator mirror is arranged on the closed end of the oil inlet pipe, and the oil level indicator mirror is a window for observing the oil level in real time.

Further, the oil inlet pipe mainly comprises a pipe body and a pipe head which are communicated with each other, wherein the outer diameter of the pipe head is larger than that of the pipe body, and the design is more stable and firm. The oil pointer sight glass is arranged at the end part of the pipe head.

The utility model adopts the above technical scheme to compare with prior art, have following technological effect: simple and reliable structure and convenient oiling.

Drawings

FIG. 1 is a main structure of an oil tank;

FIG. 2 is a schematic view of a sealing state of the refueling structure;

FIG. 3 is a schematic view of the oiling structure operating condition;

fig. 4 is a schematic structural diagram of a conventional fuel tank.

Description of the drawings: 1. the oil filling device comprises an oil tank, 2 an oil filling device, 3 lubricating oil, 4 a thread bush, 5 an oil inlet pipe, 6 an oil level indicator, 7 an O-shaped sealing ring, 8 a gasket, 9 a limiting ring, 10 an oil filling hole, 11 a screw plug and 12 a sight glass.

Detailed Description

The technical scheme of the utility model is further explained in detail with the attached drawings as follows:

the utility model provides a mechanical oil tank refuels structure only needs to open a screw hole on oil tank 1, can conveniently refuel after installing this structure to conveniently look over the oil level of oil tank simultaneously.

The utility model discloses a solve above-mentioned technical problem and adopt following technical scheme: the oiling mechanism 2 consists of a threaded sleeve 4, an oiling pipe 5, an oil level indicator sight glass 6, an O-shaped sealing ring 7 and a limiting ring 9.

The threaded sleeve 4 is arranged on the oil tank, and the oil filling pipe 5 is fixed in the threaded sleeve 4.

The oil filling pipe 5 is provided with three grooves, the two grooves on the left side are provided with O-shaped sealing rings 7 to prevent the leakage of lubricating oil 3, and the groove on the right side is internally provided with a limiting ring 9.

As a further technical scheme of the utility model, add 5 left sides installation oil level indicators sight 6 of oil pipe, can observe the oil level in the oil tank 1. Of course, the need to draw the filler tube to see the oil level in the filler hole 10 is troublesome, so that two versions are provided according to the needs of customers.

When refueling is required, the filler tube 5 is withdrawn from the threaded sleeve 4 as shown in FIG. 2. The stop collar 9 limits the distance of movement of the filler tube 5 and prevents the filler tube 5 from being pulled out and completely separating from the thread bush 4. At this time, the oil can be conveniently filled from the oil filling hole 10 in the horizontal direction. After the oil is added, the oil filling pipe 5 is returned to the thread sleeve 4, and then reliable sealing can be realized.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the claims and their equivalents.
