The periphery of the locking rod is provided with a skirt edge, and a sealing ring is arranged below the skirt edge. The utility model discloses convenient operation, ability short-term test air spring capsule are gas leakage.
Description
Technical Field
The utility model relates to an air spring capsule leakproofness detects technical field, concretely relates to air spring capsule gas tightness detects frock.
Background
The rubber air spring is a curved capsule made up by sticking rubber and net wire, and is commonly called pneumatic tyre, corrugated pneumatic tyre, air bag and bellows. Two steel plates are used to connect two ends of the capsule to form a compressed air chamber. Therefore, the sealing performance of the air spring is directly related to the stable running, comfort and safety performance of the automobile, whether the air spring leaks or not needs to be checked after being inflated, the air spring is installed on a damping frame of an automobile chassis in the past, methods such as smearing soap water and the like are generally adopted, the volume of the air spring is large, time and labor are wasted, and the detection effect is not ideal.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a convenient operation, ability short-term test air spring capsule are air spring capsule gas tightness detection frock of gas leakage.
The air spring capsule air tightness detection tool comprises an upper plug and a lower plug, wherein the lower plug is connected with the upper plug through a locking rod, an air inlet hole is formed in the locking rod, and an air outlet hole communicated with the air inlet hole is formed in one side of the locking rod.
The periphery of the locking rod is provided with a skirt edge, and a sealing ring is arranged below the skirt edge.
And the upper plug is provided with a sealing groove matched with the sealing ring.
The upper plug and the lower plug are respectively matched with the upper end and the lower end of the air spring capsule.
The lower plug is provided with blind hole threads, the upper plug is provided with through hole threads corresponding to the blind hole threads, and the locking rod is in threaded connection with the blind hole threads.
And annular sealing gaskets are arranged on the upper plug and the lower plug.
Compared with the prior art, the beneficial effects of the utility model are as follows: the sealing ring is arranged in the sealing groove of the upper plug, and the sealing effect is better by adopting a double sealing groove; then the upper and lower plugs are arranged at the openings at the two ends of the air spring capsule; the locking rod passes through the upper plug (through hole thread) and is locked on the lower plug; air enters a middle air inlet hole of the locking rod, enters an air outlet hole from an air inlet hole and enters the air spring cavity from the air outlet hole; when air enters the air spring cavity, the air spring capsule expands, and two ends of the air spring capsule are attached to the upper plug and the lower plug more and more tightly; when the air pressure reaches the rated air pressure, the air spring capsule is put into water again, and whether the air spring capsule leaks air or not can be seen visually.
