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
Extensively adopt gear-box speed change in vehicle, boats and ships, engineering equipment, change the important content that machine oil is gear-box maintenance process simulation.In order to change machine oil, gear-box adopts the structure arranging oil-draining screw at oil sump.When changing oil, first back out oil-draining screw, directly waste oil is released 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, change oil often or the careless screw thread all easily damaging oil sump drain oil, cause oil sump to damage blow-by, gently then need to change oil sump, heavy then engine can be made to scrap.Inconvenient during traditional gear-box oil-draining screw structure operation, directly drain the oil and easily affect environmental hygiene.
In addition, in prior art, also have and adopt a kind of jettison gear to replace original oil-draining screw at gear case oil drain pan, it is perforate establish elastic component in former oil-draining screw, and is sealed by top compressed steel pearl or other Sealing.When draining the oil, without the need to jettison gear is screwed down, adopt to let out with the supporting special fluid of jettison gear and fill rifle and pumping unit carries out extraction waste oil.
It is be combined not firm with jettison gear that existing fluid lets out the subject matter that dress rifle exists, and sealing effect is bad, easy leakage of oil, and needle design is unreasonable, affects earial drainage speed.
Summary of the invention
The object of this invention is to provide and a kind ofly let out dress rifle in conjunction with the fluid that firm, good sealing effect, earial drainage are fast with jettison gear.
The technological scheme realizing the object of the invention employing is as follows:
Fluid provided by the invention lets 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 outer wall in the middle part of center-pole and be positioned at the wheel of unblanking that can rotate after connecting cover; Form draw-in groove between described connection cover and center-pole, the inwall connecting cover is provided with the elasticity locking bolt stretching in draw-in groove and do radial motion; Described unblank to take turns be provided with the radial motion that shifting block and described elasticity locking bolt radial fit realize 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, the 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 take turns on shifting block match with the stem of described elasticity locking bolt.
Described elasticity locking bolt is that several are evenly arranged on the described inwall connecting cover, described in the number of shifting block of unblanking to take turns 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.
Elastic packing packing ring is provided with between described connection cover and described center-pole.
Shown center-pole is positioned at and unblanks 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 comprised on the casing such as gear-box, fuel tank a, has the following advantages:
1, owing to adopting the wheel of unblanking established the connection cover of elasticity locking bolt and establish shifting block, can realize during use being connected and dismounting with the quick of jettison gear, easy to use;
When 2, being connected 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 letting out dress fluid fast, simultaneously due to the rebound effect of the elastic component after syringe needle, make it unblank to push away rifle fast under wheel effect.
The present invention except for except draining the oil, can also be used for the earial drainage of other fluid or gas and filling.
Technological scheme of the present invention is further illustrated below in conjunction with accompanying drawing.
