Description

TECHNICAL FIELD

[0001] The utility model relates to the field, especially a kind of adjustable mountain bike gas pressure shock absorbing front fork. BACKGROUND

[0002] With the improvement of people's life concept, more and more people accept cycling, and people realize the purpose of green environmental protection travel or body building through cycling. The front fork of the bicycle is an important part of the bicycle structure. The front fork component is located in the front part of the bicycle structure. Its upper end is connected with the handlebar component. The frame component cooperates with the front tube. The lower end cooperates with the front shaft component to form the guiding system of the bicycle. The front fork has a shock absorbing function. During cycling, the front fork is compressed under stress. After reaching the extreme point, it rebounds to the original length (the rebound speed is affected by the damping). It is repeatedly repeated to reduce the stress on the rider's body, reduce the bump and achieve the purpose of comfort. Among them, the bicycle gas pressure fork usually injects gas in the sleeve on the left and right sides. When the vehicle body is jolted, the piston in the sleeve slides and relies on the damping generated by the compressed gas to achieve the buffering of the jolt.

[0003] The current bicycle front fork has poor lateral protection capability. The existing Chinese patent with patent number CN218929667U discloses an anti-lateral impact bicycle front fork with full-aluminum mechanical lock, which discloses the technical scheme of "the outer wall of multiple fixing blocks on the same side is fixedly connected with a circular baffle. The outer wall of two circular baffles is fixedly connected with a buffer mechanism." Thus, the safety of the bicycle wheel can be ensured, and the bicycle front fork has the function of resisting lateral impact. However, through actual use and operation, it is found that the circular baffle structure is easily deformed inward when subjected to point impact, and can only protect the wheel in certain situations, and the protection strength cannot meet the requirements. SUMMARY

[0004] Therefore, the utility model provides a kind of adjustable mountain bike gas pressure shock absorbing front fork, and has solved the technical problems proposed in the background art.

[0005] The utility model solves the above problems through the following technical means:

[0006] This utility model discloses an adjustable air suspension fork for mountain bikes, comprising a top tube connected to the bicycle handlebars, a fork shoulder fixedly connected to the bottom of the top tube, two travel tubes fixedly connected to the fork shoulder mounting seats at both ends of the fork shoulder, two air fork barrels respectively sleeved on the outside of the two travel tubes, a fork bridge bridging the fork barrel mounting seats fixed at the upper ends of the two air fork barrels, a fork leg bridging the fork barrel mounting seats at the lower ends of the two air fork barrels for fixing to the center of the bicycle front wheel, a spring buffer connection structure detachably installed on the outside of the two fork barrel mounting seats at the upper and lower ends of the air fork barrels, and a rearwardly extending curved wing plate fixedly connected by the two spring buffer connection structures on the same side.

[0007] Preferably, the upper edge of the curved wing plate is higher than the bicycle seat.

[0008] Preferably, the inner wall of the curved wing plate is provided with a soft pad.

[0009] Preferably, the outer wall of the curved wing plate is covered with reflective tape.

[0010] Preferably, the shock absorber switch and air chamber cover of the bicycle front fork are respectively disposed on the upper end of the two fork shoulder mounting seats.

[0011] Preferably, the shock-absorbing switch is a shoulder-controlled switch or a wire-controlled switch.

[0012] As a further improvement to the above technical solution, the fork barrel mounting base at the upper end of the pneumatic fork barrel includes an annular body, the upper surface of which includes an annular upper edge and a guide surface that slopes from the annular upper edge toward the central hole.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] This utility model discloses an adjustable air-suspension front fork for mountain bikes. The original circular baffle is replaced with a curved wing plate that extends rearward. This not only provides better internal containment, covering the legs as well, and offering overall protection for the rider's body and wheels, but its curved outer wall also provides better protection against tangential friction and abrasion. Especially when the mountain bike rolls over, it can provide support and protection, ensuring the rider's safety. Moreover, the curved wing plate has an outward protruding structure, which can resist impact deformation to a certain extent and is more impact-resistant than a flat structure.

[0021] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figs. 1 to 2 As shown: The adjustable mountain bike air suspension fork of this embodiment includes an upper tube 1 connected to the bicycle handlebars, a fork shoulder 2 fixedly connected to the bottom of the upper tube 1, two travel tubes 4 fixedly connected to the fork shoulder mounting seats 3 at both ends of the fork shoulder 2, two air fork barrels 5 respectively sleeved on the outside of the two travel tubes 4, a fork bridge 7 bridging the fork barrel mounting seats 6 fixed at the upper ends of the two air fork barrels 5, a fork leg 8 bridging the fork barrel mounting seats 6 at the lower ends of the two air fork barrels 5 for fixing to the center of the bicycle front wheel, a spring buffer connection structure 9 detachably installed on the outside of the two fork barrel mounting seats 6 at the upper and lower ends of the air fork barrel 5, and a rearwardly extending curved wing plate 10 fixedly connected by the two spring buffer connection structures 9 on the same side.

[0022] The adjustable air suspension fork for mountain bikes described in this embodiment replaces the original circular baffle with a curved wing plate 10 that extends rearward. This not only provides better internal containment, enclosing the legs and offering overall protection for the rider's body and wheels, but its curved outer wall also provides better protection against tangential friction and abrasion. Especially when the mountain bike rolls over, it can provide support and protection, ensuring the rider's safety. Furthermore, the curved wing plate 10 is an outward-protruding structure that can resist impact deformation to a certain extent, making it more impact-resistant than a flat structure.

[0023] In practical applications, the upper edge of the curved wing plate 10 is higher than the bicycle seat, thus providing overall protection for the rider's lower body, making the protection safer and more reliable.

[0024] As a preferred embodiment of this invention, the inner wall of the curved wing plate 10 is provided with a soft pad (not shown in the figure). The soft pad can further protect the torso and prevent the body parts from being injured by direct collision with the curved wing plate 10.

[0026] In practical applications, for ease of operation, the shock absorption switch 11 and the air chamber cover 12 of the bicycle front fork are respectively located on the upper end of the two fork shoulder mounting seats 3. Specifically, the shock absorption switch 11 is a shoulder control switch or a wire control switch.

[0027] As a further improvement to the above technical solution, such as Fig. 3 As shown, the upper end of the pneumatic fork barrel 5 has a fork barrel mounting base 6, which includes an annular body 13. The upper surface of the body 13 includes an annular upper edge 14 and a guide surface 16 that slopes from the annular upper edge 14 toward the central hole 15. When lubricating oil is added between the stroke tube 4 and the pneumatic fork barrel 5, the lubricating oil can be added to any position of the guide surface 16 and flow along the guide surface 16 toward the central hole 15 into the space between the stroke tube 4 and the pneumatic fork barrel 5. This facilitates operation and avoids the situation where the lubricating oil flows out and is difficult to clean, thus preventing lubricating oil waste.
