Abstract
The utility model discloses an engineering mechanical level meter which is provided with a pair of bases 1 fastened on an engineering mechanical oil box shell 2 through hollow bolts 6 and a transparent liquid level display tube 3; the utility model is characterized in that a connecting interface between the transparent liquid level display tube 3 and the bases 1 is provided with an elastic bush 4; the inner wall and/or the outer wall of the elastic bush are/is provided with tooth shaped leakage-proof stop ring grooves. The utility model has the advantages of airproof performance and reliability and can be suitable for the use demands of engineering machines in various occasions.
Description
Technical field the utility model belongs to the device feature of engineering machinery, further is the liquid level gauge of fuel tank inner fluid body position liquid levels such as a kind of wheel box that is used to indicate engineering machinery, sump.
The engineering machinery liquid level gauge that background technology is used at present, as disclosed " a kind of general pasta indicating device " in No. 92219333.9, the Chinese patent, this device has advantages such as highly versatile easy to use, but because its installation at base and display tube is to have adopted flat pad assembling, in the use, particularly in the use of more complicated landform, owing to jolt, reason such as vibration makes the junction leak and transparent glass tube and base generation displacement, collision and broken invalid easily.In order to overcome this problem, task of the present utility model has been proposed, design a kind of novel engineering machinery liquid level indication liquid level gauge.
This a kind of construction machinery liquid level gauge of summary of the invention, it has and a pair ofly is fastened on base 1 and transparent liquid level display tube 3 on the engineering machinery fuel tank shell 2 by hollow bolt 6, and it is characterized in that has its inwall and/or outer wall to have the resilient bushing 4 of profile of tooth leakproof snap ring groove in the connecting interface of liquid level display tube 3 and base 1.The utility model has the advantages that, adopted resilient bushing, increased the reliability of sealing with zigzag inner wall surface, prevent that the performance of vibrating from also improving greatly, by test, can in all case use, avoided because the poorly sealed close leakage that causes of connecting portion.Its sealing characteristics is conspicuous.
Appended drawings 1 structural profile view of the present utility model, Fig. 2 is the A zoomed-in view of accompanying drawing 1.Sequence number called after in the accompanying drawings: 1, base, 2, fuel tank shell, 3, display tube, 4, resilient bushing, 5, sealing ring, 6, hollow bolt, 7, sealing gasket.
Embodiment has provided a kind of specific embodiment with reference to accompanying drawing in the accompanying drawing.This liquid level indicating device, there are two hollow bolts 6 to be fastened on base 1 on the outer wall of engineering machinery fuel tank shell 2 by sealing gasket 7, a sealing ring 5 is arranged between hollow bolt 6 and the base 1, and sealing ring 5 and sealing gasket 6 have formed base and fuel tank and extraneous sealing.Having the socket of assembling display tube on the base 1, is the liner 4 that an inwall has the profile of tooth annular groove in socket, and the effect of this profile of tooth annular groove is to prevent to leak and stop display tube loosening in the socket of base.The profile of tooth annular groove can be designed as equilateral sawtooth and hypotenuse sawtooth, and promptly limit is perpendicular to the axis of himself.If same serrate annular groove is set on the outer wall of lining, then sealing and stopping effect are more superior.So promptly can overcome effectively owing to jolt, reason such as vibration makes the junction leak and transparent glass tube and base generation displacement, collision and the problem of broken invalid easily.
