Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of novel seal gum fatigue strength tester, it includes inner cylinder body 3, the inner cylinder body 3
Outer cover outer cylinder body 2 is housed, the first seal groove 6 and are machined with the outer wall being in contact on the inner cylinder body 3 with outer cylinder body 2
Two seal grooves 7, the top of the outer cylinder body 3, which is bolted, is provided with outer cylinder body closure plate 1, the bottom peace of the inner cylinder body 3
Equipped with inner cylinder body closure plate 4, the outer rim of the inner cylinder body closure plate 4, inner cylinder body 3 and outer cylinder body 2 is all machined with bolt connecting hole 10, institute
State on bolt connecting hole 10 through long bolt 13 is provided with, the first attaching nut 11 and second is installed on the long bolt 13 and connected
Connected nut 12.
Further, the outer cylinder body 2 and inner cylinder body 3 are coordinated using gap.Coordinate by using gap between can ensureing
Gap position can enter high pressure.
Further, it is machined with outer cylinder body pressurizing port 5 in the side wall of the outer cylinder body 2；The center of the inner cylinder body closure plate 4
It is machined with inner cylinder body closure plate pressurizing port 8.Can be convenient by described outer cylinder body pressurizing port 5 and inner cylinder body closure plate pressurizing port 8
