Abstract
The utility model discloses an oil groove oil outlet structure. The oil groove oil outlet structure comprises a pull rod, a piston, a torsion spring and a driving mechanism, and is characterized in that the driving mechanism drives the pull rod to open and lock the piston, oil flows out of an oil tank through an oil outlet, and the piston is unlocked and closed after the oil is all drained. The oil groove oil outlet structure is simple in structure, convenient to maintain, high in reliability, low in cost and small in size.
Description
Technical field
The present invention relates to hold in all kinds of mechanical equipments the oil groove oil drainage structure of oil.
Background technology
At present, all need oil and the oil lubrication of refrigerant fluid Cooling and Lubricator and hydraulic oil transferring power in known all kinds of mechanical equipment.Because work the time need guarantee that the mechanical equipment fuel feeding is normal, oil groove, fuel tank, pipeline, pump consist of a circulation loop, and in work, oil pump constantly is sent to oil groove with the oil sources source, and oil groove is recovered to oil in fuel tank by outlet.Required liquid level is different owing to producing different workpiece, therefore will adjust in real time the liquid level of oil groove.In the past commonly used is drawing and pulling type oil level control structure, but the lid structure is the mechanism of a cover ascending, descending oil outlet, is comprised of oil level pull bar and bellows, rises on the oil outlet position when upwards pulling pull bar, and when pushing away downwards, the oil outlet position descends, and controls oil level with this.Still have certain altitude under compressive state due to bellows, so even oil outlet the oil in oil groove all can not be given out light when bellows is in lower end position.Also have a kind of pull bar retracing spring formula oil drainage structure oil drain structure on bottom of oil groove as a kind of in Chinese patent (200820034907.X), this structure is comprised of the pull bar of draining the oil, spring and plug cock.Above-mentioned oil drainage structure is extremely inconvenient because retracing spring is positioned at the inboard maintenance of oil groove, and long-time the use causes the deflection of spring sealing not exclusively, can't lock.
Therefore, in order to overcome above-mentioned shortcoming, provide a kind of oil groove oil drainage structure.
Summary of the invention
In order to overcome existing oil groove oil drainage structure inconvenient maintenance, the long-time use causes the deflection of spring sealing not exclusively, and the shortcoming that can't lock the invention provides a kind of oil groove oil drainage structure.
the technical solution adopted for the present invention to solve the technical problems is: a kind of oil groove oil drainage structure, its composition comprises: pull bar, piston, driver train, it is characterized in that: oil groove wall both sides are provided with driver train, driver train is connected with pull bar, driver train is provided with torsion spring, the pull bar lower end is provided with piston, driver train is provided with drive spindle, rotary drive mechanism drives pull bar, mention piston, driver train pulls out, drive spindle and pull bar lock, open drain oil, fluid is emitted, driver train inwardly pushes, driver train restoring force and the combined action of pull bar piston gravity, close drain oil, driver train exposes the oil groove wall outside and is provided with knob and torsion spring, and oil groove wall inboard is provided with drive spindle, and the inboard of driver train connects by the axle that passes the oil groove wall with the outside, torsion spring one end is connected with driver train, and the other end is connected with oil groove, the drive spindle of driver train is " L " shape, and the drive spindle end is provided with the oval through hole, and the oval hole is larger near the drive spindle end, the pull bar upper end is provided with pin, coordinates with oil groove inwall guide groove in the middle part of pull bar, and pull bar lower end and piston upper surface pass through mechanical connection.
The invention has the beneficial effects as follows: simple in structure, easy to maintenance, reliability is high, and cost is low, and volume is little.
