Invention content
The purpose of the present invention is intended to provide a kind of sealing structure convenient for disassembly and assembly, good seal performance, to overcome the prior art
In shortcoming.
By a kind of sealing structure that this purpose designs, including automobile fuel-economizing device, structure feature is the automobile fuel-economizing device
Both ends be respectively arranged with it is coupled logical take over, the end taken over packet be connected in sealing shroud；The sealing shroud include with
The expander that cylinder connects, cylinder, which is socketed in, to be taken over, and expander is blocked in the openend taken over, and expander is in hollow ball-shape,
The diameter of expander is more than the diameter of cylinder.
Further, the tip inside of the cylinder is provided with lead-in chamfered.
Further, more than one retaining protrusion is provided on the inner wall of the cylinder.
Further, it is provided with more than one non-slip process on the outer wall of the cylinder.
Further, the non-slip process is annularly set.
Further, the end taken over is tapered, and the end set taken over has retaining step.
The both ends of automobile fuel-economizing device in the present invention be respectively arranged with it is coupled logical take over, the end taken over packet connect
In sealing shroud；The sealing shroud includes the expander to connect with cylinder, and cylinder, which is socketed in, to be taken over, and expander closure is being taken over
Openend, expander is in hollow ball-shape, and the diameter of expander is more than the diameter of cylinder；It can be effectively close by the sealing shroud
The openend of sealing-in pipe prevents sundries from falling into the inside of automobile fuel-economizing device, and the normal use of automobile fuel-economizing device is impacted, from
And improve the security performance of automobile fuel-economizing device.
Sealing shroud in the present invention includes the expander to connect with cylinder, and cylinder, which is socketed in, to be taken over, and expander blocks
The openend taken over, expander are in hollow ball-shape, and the diameter of expander is more than the diameter of cylinder, so can be directly by sealing shroud
It is socketed and blocks in the openend taken over；And pass through and more than one retaining protrusion is provided on the inner wall of cylinder, it can prevent
Sealing shroud is slipped from the openend taken over, the bonding strength for improving sealing shroud between the openend taken over.
The present invention is provided with lead-in chamfered in the tip inside of cylinder, so as to reduce sealing shroud and the openend taken over it
Between assembling intensity, improve production efficiency.
The present invention is provided with more than one non-slip process on the outer wall of cylinder；The non-slip process is annularly set,
Consequently facilitating user removes sealing shroud from taking over, manipulation strength is reduced.
In conclusion the present invention has the characteristics that convenient for disassembly and assembly, good seal performance.
