Description

Technical Field

[0001] The utility model relates to the technical field of sealing covers, in particular to a front spring sealing cover. Background Art

[0002] With the popularity of new energy vehicles in the past two years, air suspension has begun to develop rapidly in my country. The air spring is the elastic element of the air suspension system. When the traditional threaded sealing cover is used to seal the air suspension, the principle is that when the sealing cover is threadedly connected to the nozzle, the sealing ring inside the sealing cover is squeezed with the nozzle to form a sealing area. The sealing ring is prone to aging over time, and it is inconvenient to take out when replacing the sealing ring.

[0003] The existing patent (Announcement No.: CN219062298U) proposes a spring piston sealing cover body, characterized in that a sealing cover inner retaining ring is provided at the edge of the cover body, a tensioning assembly is provided on the inner side of the sealing cover inner retaining ring, the sealing cover inner retaining ring is plugged and matched with the tensioning assembly, a sealing cover outer retaining ring is provided on the outer side of the sealing cover inner retaining ring, and a buffer block is provided inside the cover body. The tensioning assembly can strengthen the connection between the cylinder or airbag and the sealing cover when the suspension is subjected to a large impact, ensuring that the suspension can work stably under various conditions.

[0004] The above-mentioned sealing cover adopts a sealing cover inner retaining ring and a tensioning component to plug and cooperate with each other in the technical solution of strengthening the connection between the cylinder body or the airbag and the sealing cover. A sealing cover outer retaining ring is arranged on the outside of the sealing cover inner retaining ring, and a buffer block is arranged inside the cover body. The stability of the sealing cover connection is ensured by the tensioning component. This solution solves the problem of the sealing cover connection stability, but does not solve the technical problem that the sealing ring inside the sealing cover is inconvenient to remove when it is aged and replaced. Therefore, we propose a front spring sealing cover to solve the above problem. Utility Model Content

[0009] Preferably, both sides of the slide groove are provided with clamping grooves.

[0010] The above technical solution is adopted: card slots are opened on both sides of the slide slot, so that when the elastic pull-up component moves downward, the sealing ring plate moves more smoothly through the cooperation between the card slot and the card block.
