Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 1-7, a corrosion-resistant bottom fork assembly comprises a bottom fork frame 11, a fixing bolt 15 and a connecting pipe 10 arranged in the hollow, wherein the bottom fork frame 11 is fixedly connected to the outer peripheral side of the connecting pipe 10, and a bracket connecting block is arranged on the bottom fork frame 11 and used for fixing a vehicle bracket;

be equipped with two detachable bearings 13 in the connecting pipe 10, the both ends of connecting pipe 10 are equipped with to keeping away from the open-sided recess of bearing 13, the inner wall that connecting pipe 10 is located the groove part and is close to connecting pipe 10 central line is equipped with the opening, the opening is with recess and connecting pipe 10 interior intercommunication, be equipped with two at least intercommunicating pores 18 on the inner wall that connecting pipe 10 is close to the connecting pipe 10 central line, be equipped with detachable cotton 12 that absorbs water in the recess, cotton 12 that absorbs water is located the opening part of recess and is protruding to connecting pipe 10 inside, cotton 12's material that absorbs water is the sponge that absorbs water, because the mounted position of chain stay is lower, will have a small amount of water to sputter in connecting pipe 10 when the vehicle goes, accessible intercommunicating pore 18 and cotton 12 absorb the storage to the water of sputtering and its inside vapor this moment.

At least two water outlet holes 17 communicated with the groove are formed in the position, on the outer periphery side of the connecting pipe 10, of the protruding portion of the absorbent cotton 12, at least two water outlet holes 17 communicated with the groove are formed in the position, on the outer periphery side of the connecting pipe 10, of the protruding portion, at least two blocking rings 14 are fixedly connected to the inner wall of the connecting pipe 10, the blocking rings 14 are located between the groove and the bearing 13, a fixing bolt 15 penetrates through the connecting pipe 10 along the direction of the center line of the connecting pipe 10, a detachable clamping plate 16 is sleeved on the fixing bolt 15, anti-skid coatings are arranged on the arc surface of the groove of the clamping plate 16, the clamping plate 16 is made of at least one of plastics and gum, after absorbing moisture, other portions of the absorbent cotton 12 converge at the protruding portion of the absorbent cotton 12 under the influence of gravity, when a vehicle bumps, the protruding portion of the absorbent cotton 12 can be extruded through the clamping plate 16, so that moisture in the absorbent cotton 12 is extruded out of the water outlet holes through the blocking rings 14, and the water after being extruded can not flow into the connecting pipe 10, thereby reducing corrosion of the water to the interior of the connecting tube 10.

When the water absorption device is installed, the bracket connecting block on the flat fork frame 11 needs to be installed downwards, at the moment, the convex part of the water absorption cotton 12 is also vertically downwards, so that water can naturally flow to the convex part of the water absorption cotton 12 under the influence of gravity, then the fixing bolt 15 is inserted, the clamping plate 16 is buckled on the shaft of the fixing bolt 15, the position of the clamping plate is adjusted to enable the convex part to be close to the side of the flat fork frame 11 and just contact the convex part of the water absorption cotton 12, so that the fixing bolt 15 drives the clamping plate 16 and the connecting pipe 10 to generate relative motion when a vehicle runs to a bumpy road section, the clamping plate 16 extrudes the water absorption cotton 12, the water accumulated by the water absorption cotton 12 is extruded out, then the water flows out through the water outlet holes 17 under the blocking of the blocking ring 14, the sputtered water can be effectively prevented from entering the connecting pipe 10, and simultaneously, the water vapor in the connecting pipe 10 is also absorbed through the communicating holes 18, the inner wall of the connecting pipe 10 and the bearing are prevented from being corroded by water, so that the service life of the bottom fork is seriously influenced.

It is to be understood that the described embodiments are merely a few embodiments of the utility model and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
