Description

Oil level gauge structure

Technical Field

The utility model belongs to the technical field of machinery, a machine dipstick structure is related to.

Background

The engine oil level gauge is an effective tool for detecting the level of the lubricating oil level of an engine, and the engine oil amount can be distinguished by checking the oil level gauge. The working dynamics of the engine can be found through the color of the engine oil, so that the engine is maintained, and faults and accidents are found in time.

Traditional machine oil chi is mostly hard plastic material or sheetmetal chi in the existing market, and traditional machine oil chi is because the machine oil colour is lighter when newly adding machine oil, differentiatees the scale mark difficulty to the volume that leads to machine oil to annotate can't correctly hold. Simultaneously, because the multitime plug of oil rule in the chi pipe (probably leading to the production of metal debris), can make chi pipe inner wall adhere to a large amount of machine oil, finally influence the reading of oil rule scale.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided an oil dip rod structure, the utility model aims to solve the technical problem that: how to effectively and clearly distinguish the oil level of the engine.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a machine dipstick structure, includes that one end has the machine dipstick body of handle, this machine dipstick structure still including being rectangular form and adopting transparent material's measuring rule head, be equipped with the oil absorption hole that extends along length direction in the measuring rule head, the oil absorption hole runs through the one end of measuring rule head, the other end of measuring rule head is connected with the other end of machine dipstick body, still be equipped with the atmospheric pressure balance hole of the external and measuring rule head oil absorption hole of intercommunication on the measuring rule head.

This machine dipstick structure sets up the measurement chi head that adopts transparent material to make through the one end at quick-witted dipstick body to be equipped with the oil absorption hole in the measurement chi head, after inserting in the machine oil, utilize the capillary phenomenon of liquid can be downthehole with the machine oil suction, because machine oil has viscosity height, the characteristics that tension is big, consequently under the liquid surface tension effect, machine oil is difficult for the outflow drippage in the oil absorption hole, can observe machine oil liquid level height and not receive the influence of machine oil colour depth, thereby effective, clear differentiateing engine machine oil liquid level.

In the above oil dipstick structure, the oil suction hole includes a straight section and a tapered oil suction port section, the large end of the oil suction port section is communicated with the straight section, and the small end of the oil suction port section penetrates through the end part of the measuring dipstick head. Through foretell setting for the internal diameter of oil absorption mouth section tip department is less than the internal diameter of straight section, and machine oil is after inhaling, because the port department diameter is less, and under the effect of cooperation liquid surface tension, machine oil is more difficult for flowing out after the machine oil chi is extracted from the chi pipe, thereby is convenient for observe the machine oil scale outside the transparent measurement chi head, thereby effective, clear differentiates engine oil liquid level.

In the above-mentioned oil dipstick structure, the dipperstick is overhead to have a head that is the taper, the oil absorption mouth section is seted up in above-mentioned head. Through foretell setting, the plug of the oil rule of being convenient for.

In foretell oil rule structure, still be equipped with upper limit scale and lower limit scale along the one end of this body coupling of oil rule toward the other end direction on the dipperstick head in proper order, upper limit scale and lower limit scale all are located the one side that the atmospheric pressure balance hole is close to the oil suction mouth section. When designing the upper and lower scale lines, attention needs to be paid to the capillary phenomenon. Capillary phenomenon refers to the attraction of liquid surface to solid surface, and when capillary is inserted into the wetting liquid, the liquid level in the tube rises and the liquid level is higher than that outside the tube. The graduation marks need to be moved upwards by a distance h on the original basis. The calculation formula is as follows:

wherein K is the surface tension of the liquid, theta is the contact angle, rho is the density of the liquid, g is the acceleration of gravity, and r is the pipe diameter. Set up atmospheric pressure balance hole in same one side of upper limit scale and lower limit scale, lie in the top of upper limit scale and lower limit scale promptly, avoid atmospheric pressure balance hole to block up, guarantee that inspiratory machine oil can be at upper and lower scaleShown at the lower limit scale.

In the oil dipstick structure, the measuring head is made of flexible transparent plastic material. The measuring tape head is made of flexible transparent plastic materials, namely the measuring tape head is of a hose structure, the inner wall of the measuring tape tube cannot be scraped, and the measuring tape head is not influenced by engine oil adhesion on the inner wall of the measuring tape tube.

In the oil dipstick structure, the measuring dipstick head and the oil dipstick body are mutually inserted and fixed in a tight fit manner. By adopting the arrangement, the connection is convenient, the replacement is convenient, and the maintenance cost is reduced. Alternatively, the measuring rule head and the oil rule body can be connected through threads.

Compared with the prior art, the oil dipstick structure of the machine has the following advantages:

1. after this dipstick structure inserts in the machine oil, utilize the capillary phenomenon of liquid can be downthehole with the machine oil suction, because machine oil has viscosity height, the characteristics that tension is big, consequently under liquid surface tension effect to the design of the oil absorption mouth section of cooperation taper, machine oil is difficult for the outflow drippage in the oil absorption hole, can observe machine oil liquid level height and not receive the influence of machine oil colour depth, thereby effective, clear discernment engine oil liquid level.

2. The measuring ruler head is made of flexible transparent plastic materials, the inner wall of the ruler pipe cannot be scraped, and the influence of engine oil adhesion on the inner wall of the ruler pipe is avoided.
