Stifled, the oily bottom blocks and is provided with through hole；Including the first conduit by made by metal material and the second conduit, the first conduit
One end and the second conduit one end activity riveting, two conduits under natural shape body be in 90 ° of angles；First conduit is blocked up from oily bottom
Through hole passes through, and is provided with sealing shroud A therebetween, the first conduit away from the one end being connected with the second conduit appearance
Face is provided with centering labelling；Second conduit is extend in oil sump vertically upward；Including torsion spring, the torsion spring is arranged on
The activity riveting position of one conduit and the second conduit, the two ends of torsion spring are fixedly connected with the medial wall of two conduits respectively；Including survey
Examination flexible pipe, the test hose are installed in the inner chamber of two conduits, and its one end extends to the upper-end part of driving of the second conduit, are tested soft
The other end of pipe is stretched out from one end that the first conduit arranges labelling, and be connected with outside pressure transducer, in test hose and
Sealing shroud B is provided between the inwall of the first conduit setting labelling one end.
The technical scheme that can also adopt of the present invention for：
Second conduit is in charge of to be sequentially connected by threaded coaxial by multistage and is constituted.
The two ends of the torsion spring are fixedly connected by way of welding with the inwall of two conduits respectively.
First conduit and the second conduit are stainless steel tube.
The sealing shroud A and sealing shroud B are silica gel sealing set.
The present invention has the advantages and positive effects that：
Conduit of this test fixture by two activity rivetings, is that the test hose for connecting external pressure sensor is built
One passage, can be easily incorporated into test hose in crankcase by the passage, realize the test of crankcase pressure.This
Test fixture has cleverly borrowed the oil-out position of oil sump, introduces frock from the position, therefore, except by existing oily bottom
It is stifled to be made outside empty set structure, to the main body of oil sump without any changes.This test fixture by by the outer end of test hose with
Outside pressure transducer connection, so that it may the convenient pressure accurately measured inside crankcase, have the advantages that it is easy to operate, separately
Outward, its structure is also fairly simple.

Specific embodiment
For the content of the invention, feature and effect of the present invention can be further appreciated that, following examples are hereby enumerated, and coordinates accompanying drawing
Describe in detail as follows：
Fig. 1 is referred to, a kind of bent axle loading pressure test fixture is made up of following sections：
Including the oily bottom stifled 1 installed in oil sump oil-out position, the oily bottom blocks and is provided with through hole.Will show
Some oil bottoms are stifled to be set to sleeve-like structure, and the oil-out of its outer surface and oil sump is yet by being threadedly coupled.
Including the first conduit 2 by made by metal material and the second conduit 3.One end of first conduit and the one of the second conduit
End activity riveting, two conduits are in 90 ° of angles under natural shape body.Specifically, it is provided with coaxial on the corresponding side wall of two conduits
Two movable riveting points, shape of two conduits at riveting end need to ensure that two conduits can be relatively rotated in place from 90 ° of angular positions
In coaxial position.Above-mentioned first conduit is passed through from the center line through hole that oily bottom is blocked up, and is provided with sealing shroud A4 therebetween.
One conduit is provided with centering labelling 5 away from the surface of the one end being connected with the second conduit, and specifically, centering labelling can be using being located at the
Mark line in one catheter outer surface is representing, it is also possible to which the laminar projection being located on the outer surface of the first conduit is representing
Deng.Above-mentioned second conduit is extend into inside oil sump vertically upward.The direction indication and the second conduit of above-mentioned centering labelling is certainly
Direction so under shape body is consistent, so, when the second conduit and the first conduit penetrate into oil sump from the oil-in of oil sump successively
Afterwards, by adjusting the first conduit, centering labelling is made to be located at the position of the top, it is ensured that the second conduit is entered in oil sump
Afterwards, in the presence of torsion spring, perpendicular upright position is turned to, the accuracy of stress test so, is ensured that.
Including torsion spring 6.The torsion spring is arranged on the activity riveting position of the first conduit and the second conduit, the two ends point of torsion spring
It is not fixedly connected with the medial wall of two conduits.Specifically, torsion spring is arranged on the position of close inwall in the inner chamber of two conduits.
Including test hose 7.The test hose is installed in the inner chamber of two conduits, and its one end extends to the second conduit
Upper-end part of driving, the other end of test hose are stretched out from one end that the first conduit arranges labelling, and are connected with outside pressure transducer
Connect.Non- table goes out pressure transducer in the accompanying drawings.Arrange in test hose and the first conduit and be provided with close between the inwall of labelling one end
Big envelope B8.
In said structure, second conduit is in charge of by multistage and is sequentially coaxially connected and composed by screw thread.Second conduit is adopted
With segmentation connection structure, can flexibly be arranged according to the height of crankcase inner engine oil liquid level, it is ensured that the second conduit it is upper
End face is always positioned at the top of machine oil liquid level.
In said structure, the inwall of the two ends of the torsion spring and two conduits is preferably using the company of being fixed by the way of welding
Connect.First conduit and the second conduit preferably adopt stainless steel tube.The sealing shroud A and sealing shroud B are preferably close using silica gel
Big envelope.
The operation instruction of this frock：
1st, first test hose is penetrated in two conduits, and in test hose be set with upper sleeve gasket B, make test hose with
First conduit forms sealing near the position of outer end；
2nd, after the position suit upper sleeve gasket A of end oily bottom block sets are mounted on the first conduit and are set in the first conduit
The position of sealing shroud A is put, makes to form in sealing contact between the first conduit and oily bottom are stifled, when centering is labeled as above-mentioned outer lug knot
During structure, finally also need to centering labelling is fixed on the outer surface of the first conduit；
3rd, after being successively inserted into the second conduit and the first conduit in crankcase from the oil-out position of oil sump, by oily bottom
It is stifled to be tightened on oil-out.During insertion, when the movable caulking part position of two conduits moves to oil-out position, downwards
The first conduit is pressed, makes the first conduit 90 ° be rotated relative to the second conduit, such two guide rail is located on same axis, so that it may will
The fore-end of the first conduit is successfully inserted in crankcase.After the second conduit enters into crankcase, in the presence of torsion spring,
Second conduit is rotated up 90 ° relative to the first conduit, realizes automatically reseting.When tighten oily bottom it is stifled after, along the circumferential direction adjust
First conduit so as on centering labelling be located at the position of the top, so ensure that second conduit in vertically upward
Position.
4th, finally one end that detection flexible pipe is located at outside the first conduit is connected with the pressure transducer of outside.Complete
After stating work, so that it may the pressure in crankcase is tested by pressure transducer.
