DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] Please refer to Figures 1-4 A novel motorcycle front shock absorber, including shock absorber cylinder 1, floating rod 2 and protection assembly, the shock absorber cylinder 1 top is inserted with floating rod 2, the protection assembly includes telescopic sleeve 3, first connector 4, second connector 5, pressure ring 6, positioning plate 7 and fastener, the shock absorber cylinder 1 top is also provided with the support ring of supporting floating rod 2, telescopic sleeve 3 is set on floating rod 2, first connector 4 and second connector 5 are arranged on the upper and lower sides of telescopic sleeve 3 respectively, second connector 5 is set on the support ring, pressure ring 6 is set on second connector 5, the inner diameter of pressure ring 6 is greater than the maximum outer diameter of telescopic sleeve 3, the outer diameter of pressure ring 6 is greater than the outer diameter of shock absorber cylinder 1, two groups of positioning plate 7 are also provided below pressure ring 6, shock absorber cylinder 1 is provided with fastener connected with positioning plate 7;

[0026] Second connector 5 below telescopic sleeve 3 is set on the support ring of shock absorber cylinder 1, and the support ring provides radial limit for second connector 5 to prevent it from sliding axially along shock absorber cylinder 1, forming the first layer fixation;

[0027] The pressure ring 6 is sleeved on the outside of the second connector 5. Its outer diameter is larger than the shock absorber 1 and is connected to the positioning plate 7 below. By pressing the second connector 5 downward, the second connector 5 and the support ring are tightly fitted, thereby enhancing the sealing effect and forming a second layer of fixation.

[0028] The minimum inner diameter of the pressure ring 6 is smaller than the maximum outer diameter of the second connector 5;

[0029] In this embodiment, the fastener includes a handle 8, a worm gear 9, a screw 10, a worm 11, an insert 12 and a protrusion 13. The upper part of the shock absorber cylinder 1 is also provided with the protrusion 13, and a movable cavity is provided in the protrusion 13. Receiving grooves are symmetrically provided on the front and rear sides of the protrusion 13. The insert 12 is provided in the receiving groove. The worm gear 9 and the worm 11 are meshed with each other. One end of the worm 11 passes through the protrusion 13 and is connected to the handle 8. The left and right sides of the center of the worm gear 9 are provided with screws 10 extending into the receiving groove. One end of the insert 12 is threadedly connected to the screw 10, and the other end of the insert 12 is plugged into the corresponding positioning plate 7. The positioning plate 7 is provided with a socket adapted to the insert 12.

[0030] The positioning plate 7 of the pressure ring 6 is connected to the shock absorber 1 via fasteners. After the plug 12 is inserted into the socket of the positioning plate 7, it restricts the upward and downward movement of the pressure ring 6, further locking the second connector 5 on the support ring, forming a third layer of fixation. The three-layer structure works together to prevent the telescopic sleeve 3 from separating from the shock absorber 1, ensuring dustproof effect.

[0031] Turning the handle 8 with the friction grooves 20 rotates the worm 11 in the movable cavity of the protrusion 13. The worm 11 meshes with the worm wheel 9, causing the worm wheel 9 to rotate. The screws 10 on both sides of the center of the worm wheel 9 rotate synchronously with the worm wheel 9. Because the insert 12 is threadedly connected to the screw 10 and is restricted by the receiving slot and cannot rotate, the insert 12 extends outward along the receiving slot and is accurately inserted into the socket of the positioning plate 7.

[0032] Turn the handle 8 in the opposite direction, the worm 11 drives the worm wheel 9 to rotate in the opposite direction, and the screw 10 drives the insert 12 to retract into the receiving groove, disengaging from the socket of the positioning plate 7 and the slot of the hinge frame 17. At this time, the pressure ring 6 and the telescopic sleeve 3 can be removed for maintenance or replacement;

[0033] In this embodiment, a reflector is also provided on the protrusion 13. The reflector includes a hinged frame 17, a hinge shaft 18, and a reflector 19. The hinged frame 17 is in a U-shape. The hinge shafts 18 are symmetrically provided on the front and rear sides of the lower portion of the protrusion 13. The lower portions of the inner walls of the two free ends of the hinged frame 17 are hinged to the hinge shafts 18. The upper portions of the inner walls of the two free ends of the hinged frame 17 are provided with slots that are compatible with the insert block 12. The reflector 19 is provided at the end of the hinged frame 17 away from the protrusion 13. The upper portion of the hinged frame 17 is also provided with a notch that is compatible with the handle 8.

[0034] The insertion block 12 extends outward along the receiving groove, is accurately inserted into the insertion hole of the positioning plate 7, is inserted into the insertion slot of the hinge frame 17 of the reflecting piece at the same time, and the locking of the protection assembly is completed; when the insertion block 12 locks the positioning plate 7, the end of the insertion block 12 is inserted into the insertion slot of the hinge frame 17 at the same time, the hinge frame 17 is unfolded with the hinge shaft 18 as the fulcrum, the reflecting plate 19 is perpendicular to the shock-absorbing cylinder 1, the reflecting plate 19 reflects light in the night or low-light environment, the visibility of the vehicle is improved, and the riding safety is improved;

[0035] If the insertion block 12 is withdrawn from the insertion slot due to vibration or the like, the hinge frame 17 loses support and naturally droops under the action of gravity, and the reflecting plate 19 is no longer kept in the vertical unfolded state. The user can judge whether the fastener is loose by observing the inclination of the reflecting plate 19, and timely relock to avoid dust-proof failure caused by the falling of the protection assembly.

[0036] The shock-absorbing cylinder 1 is provided with an axle connecting head 14 below, is provided with a disc brake connecting head 15 on one side, and is provided with mudguard connecting heads 16 on both sides close to one end of the floating rod 2; the convex block 13 is arranged between the two groups of mudguard connecting heads 16, the axle connecting head 14 (connecting the front wheel), the disc brake connecting head 15 (equipped with the disc brake), and the mudguard connecting head 16 (fixing the mudguard) of the shock-absorbing cylinder 1 realize integrated installation with the components of the whole vehicle, and the convex block 13 is located between the mudguard connecting heads 16 and does not interfere with the work of other components.

[0037] The rounded design of the end of the insertion block 12 facilitates smooth insertion into the insertion hole and the insertion slot, and reduces wear; and the friction lines 20 of the handle 8 increase the gripping force, and avoid slipping during operation.
