Abstract
The utility model discloses an oil pump gas tightness experiment end cap, include locking screw, locating lever, sealed piece and advance oil pipe, the locking screw suit in in the locating lever, and it passes pass through behind the locating lever sealed piece with it connects to advance oil pipe. The utility model discloses a machinery presss from both sides tight mode and makes that the end cap leakproofness is good, easy operation, efficient, and the processing mode is simple, the cost of manufacture low, and the suitability is strong, the product convenience of remodeling.
Description
Technical field
The utility model relates to a kind of experiment plug, relates in particular to a kind of oil pump air-tightness experiment plug.
Background technology
Power steering oil pump is in air-tight test process, owing to coordinating not between test plug and oil inlet pipeClosely, easily cause gas leakage; Because test plug need to be pressed with hand, easily cause the waste of manpower, andAnd accuracy and test efficiency that cannot guarantee test.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of oil pump air-tightness experiment stifledHead.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises tie down screw, backstay, sealing block and oil inlet pipe, described tie down screw suitIn described backstay, and it is through being connected with described oil inlet pipe by described sealing block after described backstay.
The utility model is preferred, and a side of described sealing block is provided with sealing block base, described sealing block peaceBe loaded on described sealing block base.
The utility model is preferred, and a side of described backstay is provided with air inlet connections.
The utility model is preferred, and a side that is positioned at described air inlet connections is provided with locating piece, described locationPiece is connected with the limiting plate of fixing described oil inlet pipe by interior hexagonal cylindrical hook bolt.
The beneficial effects of the utility model are:
The utility model by the mode of mechanical grip make plug good airproof performance, simple to operate, efficiency is high,Processing mode is simple, cost of manufacture is low, and applicability is strong, and product is remodeled conveniently.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of oil pump air-tightness experiment plug described in the utility model.
In figure: 1-tie down screw, 2-backstay, 3-air inlet connections, 4-locating piece, 5-sealing block base,Hexagonal cylindrical hook bolt, 8-oil inlet pipe, 9-limiting plate in 6-sealing block, 7-.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises tie down screw 1, backstay 2, sealing block 6 and oil inlet pipe 8,Tie down screw 1 is set in backstay 2, and it is rear by sealing block 6 and oil inlet pipe 8 through backstay 2Connect.
As shown in Figure 1, a side of sealing block 6 is provided with sealing block base 5, and sealing block 6 is installed on sealing blockOn base 5.
As shown in Figure 1, a side of backstay 2 is provided with air inlet connections 3.
As shown in Figure 1, a side that is positioned at air inlet connections 3 is provided with locating piece 4, and locating piece 4 is by interior sixAngle cylinder head bolt 7 is connected with the limiting plate 9 of fixing oil inlet pipe 8.
In sum, the utility model is in the parallel oil inlet pipe 8 U-shaped draw-in groove that is placed on limiting plate 9, withSealing block 6 is combined closely, and sealing block 6 adopts polyurethane elastomer material, and sealing property is better, sealing block 6Be pressed into sealing block base 5 grooves, at the bottom of sealing block, 5 are threaded connection with tie down screw 1, rotational lockScrew rod 1 moves in the horizontal direction oil inlet pipe 8, ensures that the position of limiting plate 9 is motionless can lock oil inlet pipe 8,Play sealing function, and limiting plate 9 connects locating piece 4 by bolt 7, locating piece 4 is threaded connection fixedPosition bar 2, backstay 2 is threaded connection tie down screw 1, and rotational lock screw rod 1 can ensure backstay 2Position be not moved, ensured that the position of limiting plate 9 is fixed, so rotational lock screw rod 1 energy simultaneouslyEnough by locked oil inlet pipe 8, air inlet connections 3 is threaded connection backstay 2, only need to be by solid air inlet pipe 8Fix on the air-tightness that can ensure a whole set of frock in air inlet connections 3; The utlity model has simple in structure,The advantage that stable performance and service life are grown.
Those skilled in the art do not depart from essence of the present utility model and spirit, can have various deformation scheme realExisting the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby officeLimit interest field of the present utility model, the equivalence knot that all utilization the utility model descriptions and accompanying drawing content are doneStructure changes, within being all contained in interest field of the present utility model.
