Description
Technical field
The invention belongs to and let out dress fluid device, be specifically related to a kind of fluid and let out dress rifle.
Background technique
In vehicle, boats and ships, engineering equipment, extensively adopt gear-box speed change, more change engine oil is the important content of gear-box maintenance and maintenance.For change engine oil more, gear-box adopts the structure that oil-draining screw is set at oil sump.While changing oil, first back out oil-draining screw, directly waste oil is emitted from drain oil, then add new machine oil from oil filler.All oil-draining screw must be screwed down owing to often changing once oil, discharge oil and screw on again, changed oil often or all easily damaged because of carelessness the screw thread of oil sump drain oil, cause oil sump to damage blow-by, gently need to change oil sump, heavy can make engine scrap.Inconvenience when traditional gear-box oil-draining screw structure operation, directly drains the oil and easily affects environmental hygiene.
In addition, in prior art, also have at gear case oil drain pan and adopt a kind of jettison gear to replace original oil-draining screw, it is perforate establish elastic component in former oil-draining screw, and seals by top compressed steel pearl or other Sealing.While draining the oil, without jettison gear is screwed down, the supporting special fluid of employing and jettison gear lets out dress rifle and pumping unit carries out extraction waste oil.
It is be combined not firmly with jettison gear that existing fluid is let out the subject matter that dress rifle exists, and sealing effect is bad, easily leakage of oil, and syringe needle designs unreasonable, affects earial drainage speed.
Summary of the invention
The object of this invention is to provide a kind of firm, good sealing effect, the fast fluid of earial drainage of being combined with jettison gear and let out dress rifle.
The technological scheme that realizes the object of the invention employing is as follows:
Fluid provided by the invention is let out dress rifle, comprise tubular center's bar, be actively installed on center-pole front end can axial motion elasticity thimble, be fixedly located at connection cover on the anterior outer wall of center-pole, be actively installed on center-pole middle part outer wall and be positioned at the wheel of unblanking that can rotate connecting after cover; Between described connection cover and center-pole, form draw-in groove, the inwall that connects cover is provided with and stretches into the elasticity locking bolt that does radial motion in draw-in groove; The described wheel of unblanking is provided with shifting block and described elasticity locking bolt radial fit realizes the radial motion of elasticity locking bolt.
Described elasticity thimble is located in described center-pole, comprises syringe needle and is located at the cylindrical shell at syringe needle rear portion, elastic member between cylindrical shell and center-pole; Described syringe needle is connected with described cylindrical shell by lambdoid support.
Described elasticity locking bolt is provided with axial stem, described in unblank wheel on shifting block match with the stem of described elasticity locking bolt.
Described elasticity locking bolt is that several are evenly arranged on the inwall of described connection cover, described in the number of shifting block of unblanking on wheel corresponding with the number of described elasticity locking bolt.
Described shifting block adopts inclined-plane or cambered surface to match with the stem of described elasticity locking bolt.
Between described connection cover and described center-pole, be provided with elastic packing packing ring.
Shown in be positioned on center-pole and unblank to be fixed with handle after wheel, the tail end of center-pole is connected with oil pick-up tube by pipe joint.
The present invention can support the use with being located at the jettison gear comprising on the casing such as gear-box, fuel tank a, has the following advantages:
1, due to the connection cover of elasticity locking bolt is established in employing and establish shifting block unblank wheel, when use, can realize with the quick of jettison gear and being connected and dismounting, easy to use;
2, while connection with jettison gear, there is good sealing effect, realize sealing completely, prevent leakage of oil, gas leakage;
3, owing to adopting the syringe needle of large area of passage, can realize and let out fast dress fluid, the while is due to the rebound effect of the elastic component after syringe needle, makes it unblank under wheel effect, to push away fast rifle.
The present invention is except for draining the oil, and can also be used for the earial drainage of other fluid or gas and filling.
Further illustrate technological scheme of the present invention below in conjunction with accompanying drawing.
