Specific embodiment
The utility model is further described below with reference to specific attached drawing.
In Fig. 1, including block 1, procapsid 2, inner sleeve 3, housing 4, the first elastic sealing element 5-1, the second elastic sealing element 5-2, back casing 6, support pads 7, mandrel 8, elastic cylindrical pin 9, handle 10, from lock section 11.
As shown in Figure 1, one of embodiment engine cylinder cap cam hole oil duct side leakage plugging device, including block 1, Block 1 is threadedly coupled mandrel 8, and mandrel 8 is detachable hinged by elastic cylindrical pin 9 and handle 10, and inner sleeve 3 is arranged on the outside of mandrel 8, Housing 4 is set on the outside of inner sleeve 3, is arranged on the right side of the first elastic sealing element 5-1 on the left of housing 4 and second elastic sealing element 5-2 is set, In the embodiment, the first elastic sealing element 5-1 and the second elastic sealing element 5-2 are O-ring, in other implementations of the utility model In example, the first elastic sealing element 5-1 and the second elastic sealing element 5-2 can be the elastic sealing element of other shapes.First elasticity is close It is provided with procapsid 2 between sealing 5-1 and block 1, back casing 6,6 right side of back casing are set on the right side of the second elastic sealing element 5-2 Support pads 7 are set.Procapsid 2 and back casing 6 are provided with drainage hole, and water enters when leak test in water after can preventing workpiece from inflating This tool and can not be discharged, to generate corrosion, while being convenient for blow dried inner cavity.10 lower part of handle is cylinder, facilitates behaviour Make.10 end of handle is provided with from lock section 11, is the plane vertical with 10 length direction of handle from lock section 11, when 10 front end of handle From lock section 11 and 7 plane contact of support pads, handle 10 is in the lock state, will not rotation, swift to operate, reliable operation.
The specific installation applicable cases of the utility model are as follows: first placing a device into cylinder head cam oilhole road, at this time bullet Property straight pin 9 and handle 10 between angle be 90 degree and inclined oil hole of air be located at the first elastic sealing element 5-1 and second elasticity it is close Between sealing 5-2, the positional relationship of the first elastic sealing element, the second elastic sealing element and workpiece hole wall is as shown in Figure 4 at this time.So Handle 10 is rotated counterclockwise around elastic cylindrical pin 9 to from lock section 11 and 7 plane contact of support pads, the cam of 10 front end of handle afterwards Structure forces support pads 7, back casing 6, housing 4 axially to move left on mandrel.Whole device turns to work in installation site Not by horizontal force when position, so the position of block 1 immobilizes, support pads 7, back casing 6, housing 4 are rigid element, such as Shown in Fig. 3, horizontal displacement that handle 10 pushes above-mentioned component to generate when turning to operating position from installation site can only be by First elastic sealing element 5-1 and the second elastic sealing element 5-2 generates flexible deformation to absorb.As shown in figure 5, the first elastic packing Part 5-1 and the second elastic sealing element 5-2 by procapsid 2, housing 4, back casing 6 and workpiece cam hole wall extruding and deform, To form ring packing between housing 4, the first elastic sealing element 5-1, the second elastic sealing element 5-2, workpiece cam hole wall Chamber completes the closure to inclined oil hole of air.
