Adjustable length soil removal foot

The present invention relates to a bicycle accessory, and more particularly to a soil removing foot connected to a frame and a soil removal room.

Generally, the mudguard of a bicycle is mounted on the frame of the bicycle through the mudguard stay and is located above the wheel to shield the dust and water from being carried when the wheel rotates. Since the bicycle may be replaced with wheels of different sizes or different configurations of the soil and the frame, the length of the soil removal foot needs to be telescopically adjustable to suit different installation requirements, such as the prior art documents GB 2492842A and TW. In the patent case of I374822, there is a technique of adjusting the length of the soil to adjust the length of the foot, but all the lengths of the soil must be adjusted according to the number of segments. Therefore, the adjustment of the length is not fine enough, and it is inevitable that there will be soil removal. If the length is too short, it cannot be installed between the soil and the frame, or if the length is too long, the two opposite ends must be connected to the soil and the frame separately, and the curved soil is not only not Beautiful and curved soil will also produce a restoring force that causes the soil to be offset from the frame, so that the soil is in an unstable installation state relative to the frame, which is easy to cause the soil to be removed from the script and the soil. The stress at the joint of the frame accumulates, causing the soil to break.

In addition, the prior art document US Pat. No. 8,172,246 B2 proposes a technique of adjusting the length of the soil by the stepless telescopic adjustment, but requires additional tools for operation when adjusting the length, which increases the inconvenience when installing the soil to remove the foot, and the prior art document EP 1036731B1 The patent discloses that the quick-release connector at the end of the clip-off soil is provided with a resilient split clip and is adjusted with a lock ring, but the length of the quick-release joint and the depth of the elastic split clip are limited, so the soil is removed. The length of the telescopic adjustment is also limited.

Therefore, the object of the present invention is to provide an adjustable length soil removing leg which has no length adjustment and length adjustment, no additional tools for operation, and a large expansion length.

Thus, the novel adjustable length soil removing leg comprises a rod set, a first joint set, and a second joint set.

The rod set is telescopically adjustable, and includes a female rod member having a set of inlets, a sub-bar member partially sleeved in the female rod member by the sleeve inlet, and a rod member disposed adjacent to the rod member A threaded portion of one end of the inlet and a locking member screwed to the screw portion for restricting movement of the sub-bar member relative to the female member. The first link set is coupled to one end of the sub-bar member that is not nested in the female bar member. The second link set is coupled to the end of the set of rods opposite the sleeve. Wherein, the length of the rod set is fully extended by L1, the length of the rod set is fully contracted by L2, and the set of rods satisfies L1/L2≧1.3.

The utility model has the advantages that the length of the new type can be adjusted by using the rod set which can adjust the length without the length of the telescopic adjustment, so that the first joint group and the second joint group can be connected with the soil and the frame respectively. After the adjustment is completed, the fastener can be rotated in a locking direction without using a tool to fix the sub-bar member and the female member, thereby achieving the effect of convenient operation and installation. Furthermore, the member set satisfies L1. /L2≧1.3, greatly increasing the elongation of the rod group to match the various distances between the soil and the frame, and finally reaching the rod group can support the soil removal without bending deformation, so that the soil is divided relative to The frame is in a stable installation.
