In order to solve the above problems, the Chinese patent document with publication number CN218703697U discloses a motorcycle steering lower connecting plate assembly, which fixes the steering rod by squeezing the fixing part with a clamping part. However, after it is fixed, a gap will still be generated between the steering rod and the connecting plate. After long-term use, dust and other impurities will accumulate in the gap, resulting in increased wear and tear, and also reducing the stability of the fixation. In order to solve the above problems, the utility model provides a front fork connecting plate. Utility Model Content

[0003] In response to the above-mentioned technical deficiencies, the purpose of the present utility model is to provide a front fork link plate.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides a front fork connecting plate, such as Figures 1 to 4 shown.

[0030] Example 1:

[0031] A front fork connecting plate includes a plate body 1, and a plurality of positioning blocks 2 are fixedly connected to the plate body 1. The plurality of positioning blocks 2 can play an auxiliary positioning role during the installation process, making it convenient for the staff to install. Both ends of the plate body 1 are fixedly connected to a clamp sleeve 3, and the clamp sleeve 3 can be interconnected with the front fork shock absorber. The middle part of the plate body 1 is fixedly connected to a shaft sleeve 4, and the shaft sleeve 4 is interconnected with the direction rod.

[0032] The clamp sleeve 3 is provided with an opening, and the two sides of the opening of the clamp sleeve 3 are fixedly connected with a floating block 12 and a fixed block 13 respectively. The fixed block 13 is fixedly connected to the plate body 1. The floating block 12 and the fixed block 13 are both provided with threaded holes, and the internal threads of the threaded holes are connected with bolts 15. Figure 1 As shown, by rotating the bolt 15 clockwise, the distance between the two ends of the opening of the clamp sleeve 3 can be shortened, so that the clamp sleeve 3 and the front fork shock absorber can be connected to each other.

[0033] A locking assembly is installed inside the shaft sleeve 4, which can lock the steering rod, thereby connecting the steering rod and the shaft sleeve 4 together. When the locking assembly locks the steering rod, the locking assembly will fit tightly with the outer ring surface of the steering rod, thereby preventing dust and other impurities from entering the interior of the shaft sleeve, causing increased wear and affecting the stability of the fixation.

[0034] The locking assembly includes an extrusion ring 6, which is threadedly connected to the inner ring surface of the sleeve 4 through an external thread provided on its outer ring surface (a corresponding internal thread is provided on the inner ring surface of the sleeve 4, and the threaded connection between the internal thread and the external thread is a prior art, so the present invention will not go into details. At the same time, in order to make the display effect of the drawings better, the internal thread and the external thread are not shown in the drawings). A fixing ring 7 is fixedly connected to the inside of the sleeve 4, and the outer ring surface of the fixing ring 7 fits with the inner ring surface of the extrusion ring 6. A plurality of spring pieces 8 are fixedly connected to the upper end face of the fixing ring 7. The shape of the spring pieces 8 is arc-shaped, and the plurality of spring pieces 8 are evenly distributed along the circumference of the fixing ring 7.

[0035] The upper end of the inner ring surface of the extrusion ring 6 is a funnel shape with a thin top and a thick bottom. The outer side surface of the upper end of the spring 8 is adapted to the inner ring surface of the upper end of the extrusion ring 6 (the side of the spring 8 away from the axis of the fixing ring 7 is the outer side). Figure 1 As shown, rotating the extrusion ring 6 clockwise can make the extrusion ring 6 move toward the inside of the sleeve 4, so that the inner ring surface of the upper end of the extrusion ring 6 squeezes the spring piece 8, so that multiple spring pieces 8 simultaneously hold and lock the steering rod, thereby fixing the steering rod. Furthermore, in order to make the fixing effect of the spring piece 8 better, a convex strip 9 is fixedly connected to the inner ring surface of the upper end of the spring piece 8. The material of the convex strip 9 is rubber, which can increase the friction between the steering rod and improve the fixing effect of the spring piece 8.

[0036] Example 2:

[0037] On the basis of Example 1, in order to prevent dust and other impurities from entering between the sleeve 4 and the direction rod, causing serious wear and reduced connection stability, a groove 10 is provided inside the upper end side wall of the extrusion ring 6, and the opening of the groove 10 is located on the inner ring surface of the extrusion ring 6. A rubber ring 11 is fixedly connected to the notch of the groove 10. When the extrusion ring 6 squeezes the spring piece 8, the extrusion ring 6 will also be subjected to corresponding force, which will cause the side wall of the groove 10 to be squeezed and deformed, and the air pressure inside the groove 10 will increase, which can then cause the rubber ring 11 to be compressed and expanded, and fit tightly with the outer ring surface of the direction rod, thereby preventing dust and other impurities from entering between the sleeve 4 and the direction rod.

[0038] Example 3:

[0039] On the basis of embodiment 1, in order to avoid the rigid contact between the clamp sleeve 3 and the front fork shock absorber, which is affected by vibration during long-term use and is easily damaged, an annular groove 14 is provided on the inner annular surface of the clamp sleeve 3, and a buffer sleeve 5 is installed inside the annular groove 14. The material of the buffer sleeve 5 is rubber. The buffer sleeve 5 fits with the groove wall of the annular groove 14 under the action of its own elastic force. The buffer sleeve 5 is provided with an opening adapted to the clamp sleeve 3, and the open end of the buffer sleeve 5 is folded outward, and the folded end of the buffer sleeve 5 is provided with a threaded hole adapted to the threaded hole on the fixing block 13. The inner diameter of the threaded hole of the floating block 12 is larger than the inner diameter of the threaded holes on the buffer sleeve 5 and the fixed block 13. The shape of the threaded column of the bolt 15 is a stepped shaft. When the bolt 15 is rotated clockwise, the step of the bolt 15 will push the buffer sleeve 5, so that the buffer sleeve 5 completely wraps the front fork shock absorber. Then, the bolt 15 is continuously rotated clockwise to move the floating block 12 toward the fixed block 13, so that the clamp sleeve 3 locks the front fork shock absorber. The setting of the buffer sleeve 5 can buffer the space between the clamp sleeve 3 and the front fork shock absorber to avoid damage due to vibration after long-term use.

[0040] The buffer sleeve 5 adopts the above configuration, and a gap can be left during installation to facilitate installation. After installation, the buffer sleeve 5 can completely wrap the front fork shock absorber, thereby providing better protection for the front fork shock absorber.

[0041] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
