Description

Technical Field

[0001] This utility model relates to the field of motorcycle cradle technology, specifically an adjustable motorcycle cradle device. Background Technology

[0002] With social development, motorcycles are becoming increasingly common as an important means of transportation, especially in rural and underdeveloped areas where they are widely used for carrying goods and people or for personal transportation. However, due to the relatively backward road infrastructure in rural and underdeveloped areas, road conditions vary greatly, with many areas still consisting of dirt roads or gravel roads. The bumpy and uneven road surface significantly affects the comfort of motorcycles.

[0003] Existing patent CN2769165Y discloses an adjustable rocker arm for motorcycles. While this patent solves the problem of the fixed connection between the existing fork connecting rod and the rocker arm, preventing adjustment of the shock absorber's stress point, it requires rotating the adjusting bolt first and then securing it with a locking nut, leading to inconvenience in adjustment. Therefore, an adjustable rocker arm device for motorcycles is invented. Utility Model Content

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0005] An adjustable rocker arm device for motorcycles includes a swingarm, a rear shock absorber, and a triangular rocker arm. The bottom of the swingarm has a swingarm connecting rod, one end of which is connected to the triangular rocker arm via a sliding assembly. The sliding assembly includes:

[0006] A rectangular limiting groove is formed on the bottom end of the triangular plate cradle;

[0007] The slider is slidably connected in a rectangular limiting groove through a limiting component, and a third screw hole is provided on the slider to connect with the flat fork connecting rod;

[0008] A fixing component for fixing a slider in a rectangular limiting groove, the fixing component being disposed on the slider.

[0009] As a preferred embodiment of the adjustable rocker arm device for motorcycles described in this utility model, the left end of the triangular rocker arm is provided with a first screw hole for connecting to the rear rocker arm, and the right end of the triangular rocker arm is provided with a second screw hole for connecting to the shock absorber.

[0010] As a preferred embodiment of the adjustable rocker arm device for motorcycles described in this utility model, one end of the shock absorber is provided with a shock absorber support point on the frame, and one end of the flat fork is provided with a flat fork support point.

[0011] As a preferred embodiment of the adjustable rocker arm device for motorcycles described in this utility model, the front side of the triangular rocker arm is provided with three sets of scale lines, and the scale lines are located on one side of the rectangular limiting groove. The front side of the slider is provided with a marking line, and the marking line can point to the scale line.

[0012] In a preferred embodiment of the adjustable rocker arm device for motorcycles described in this utility model, the limiting component includes:

[0013] Limiting holes are provided on both sides of the triangular plate cradle located in the rectangular limiting groove;

[0014] Limiting rods are fixedly installed at both ends of the slider, and the limiting rods are slidably connected in the limiting holes.

[0015] In a preferred embodiment of the adjustable rocker arm device for motorcycles described in this utility model, the fixing component includes:

[0016] A square groove is formed in the middle of the slider;

[0017] A square rod, which is slidably connected in a square groove, with its end extending outside the groove.

[0018] In a preferred embodiment of the adjustable rocker arm device for motorcycles described in this utility model, the fixing component further includes:

[0019] A positioning rod is fixedly installed on the bottom of the square rod and slidably connected to the bottom end of the slider;

[0020] The triangular plate cradle located below the rectangular limiting groove has three sets of positioning grooves aligned with the scale lines, and the positioning rod is inserted into one of the positioning grooves.

[0021] In a preferred embodiment of the adjustable rocker arm device for motorcycles described in this utility model, the fixing component further includes:

[0022] A guide groove is provided on the triangular plate cradle located above the rectangular limiting groove;

[0036] The sliding component includes: a rectangular limiting groove 20, a slider 21, and a fixing component for fixing the slider 21 in the rectangular limiting groove 20;

[0037] A rectangular limiting groove 20 is formed on the bottom end of the triangular rocker arm 15. The slider 21 is slidably connected in the rectangular limiting groove 20 through the limiting component. The slider 21 is provided with a third screw hole 18 connected to the flat fork connecting rod 13. The fixing component is provided on the slider 21. Three sets of scale lines 40 are formed on the front side of the triangular rocker arm 15. The scale lines 40 are located on one side of the rectangular limiting groove 20. The front side of the slider 21 is provided with a marking line 41. The marking line 41 can point to the scale line 40.

[0038] The limiting assembly includes: a limiting hole 22 and a limiting rod 23;

[0039] Limiting holes 22 are provided on the triangular plate cradle 15 located on both sides of the rectangular limiting groove 20. Limiting rods 23 are fixedly installed at both ends of the slider 21, and the limiting rods 23 are slidably connected in the limiting holes 22.

[0040] The fixing components include: square groove 30, square rod 31, positioning rod 32, positioning slot 33, guide slot 34, guide rod 35, and spring 36;

[0041] A square groove 30 is formed in the middle of the slider 21. A square rod 31 is slidably connected in the square groove 30, and the end of the square rod 31 extends outside the square groove 30. A positioning rod 32 is fixedly installed on the bottom of the square rod 31 and is slidably connected to the bottom end of the slider 21. Three sets of positioning grooves 33 are formed on the triangular plate cradle 15 located below the rectangular limiting groove 20, which are aligned with the scale line 40.
