New Description: [New Technology Field] This creation is about a pneumatic shock absorber front fork before the air pressure shock absorber. It can be adjusted to the preloading day: a lightweight and practical shock absorber Front fork design. ...7 'can achieve good [previous technique] According to the known structure of the front of the bicycle, the main private person Du &^; is formed by the frog and the shock absorber e, the shock absorber is in Avoid ^ ^ ^ 正吕内' with MCU (Acorn (four) body) shock seat tube or return spring as the main body of the shock absorber, Qing shock seat officer is to use the worm gear and the rod drive system to adjust the derby π a &丨Pressure®, which can be used as a cushioning shock absorber for bicycle riding, and allows the rider to feel a more comfortable riding effect. However, the brain suspension is heavier. In the shock absorber riser, it will cause the appearance of the outer h and the mouth, that is, it is quite cumbersome and does not look at the second, which hinders the lightweight development trend of the bicycle. This is the current self-defense and *6, in the shock absorber. The problems caused by the structure, and the people who are waiting to work hard to improve. [New content] The purpose of this creation is to provide a "pneumatic shock absorber front fork" which is provided with a dust jacket, an outer tube cover, an outer tube and an axial center on the front fork sleeve, and is externally A gas block is arranged in the tube, and a sealed air chamber is formed in the outer tube to achieve the shock-absorbing effect. # has the advantages of light weight and light weight, and the M320527 v has a novel appearance and can be used with various forms before the casing. Moreover, the practical effect of the inflation adjustment preload can be achieved, and it is more suitable for the user to operate. In order to achieve the structural characteristics and technical content of the above purpose, the creation "before the air pressure shock absorber" includes: a front fork bushing, a dust jacket and an outer pipe cover on the front casing and an outer pipe cover A perforation is arranged on the circumference; an outer tube 'the bottom end of the outer tube is disposed in the outer tube cover, and a DU bearing is disposed on the inner wall of the bottom end of the outer tube; an axial center is inserted in the outer tube and passes through the DU bearing, on the shaft A buffer rubber is disposed on the peripheral surface of the bottom end of the core, and an air hole is disposed above the middle portion of the shaft center, and a through hole is arranged in the shaft center to connect with the air hole, the through hole passes through the top end of the shaft center, and the through hole communicates with the through hole of the outer tube cover; a gas blocking plug is disposed in the outer tube, and a sealing air chamber is formed between the shaft and the shaft, and the through hole of the shaft communicates with the sealing air chamber; the air nozzle is disposed in the perforation of the outer tube cover, and the outer tube The cover perforation is in communication with the through hole of the shaft center. With this design, a lightweight suspension front fork is formed, which has a beautiful appearance and a shock absorber, and can be inflated to adjust the preloading load, and can be set on various different fork legs, which is suitable for bicycle design. No potential. [Embodiment] The matching port is shown in 帛— and II. The original “Pneumatic M320527, before shock absorber” includes: a front casing (1), which is placed on the front fork bushing. a dust jacket (3) and an outer tube cover (7), a perforation (70) is provided on the outer surface of the outer tube cover (7); an outer tube (12), and an outer tube (12) bottom end is disposed on the outer tube cover (7) In the inner wall of the outer tube (12), a du bearing (5) is disposed on the inner wall of the outer tube (12); an axial center (2) is inserted in the outer tube (1 2 ) and passes through the DU bearing (5) on the shaft The core (2) is provided with a buffer rubber (4) adjacent to the bottom surface of the bottom end, • an air hole (2 1 ) is disposed above the middle portion of the shaft center (2), and a through hole (22) is disposed in the center of the core (2). The air holes (21) are connected, the through holes (2 2 ) pass through the top end of the shaft center (2), and the through holes (2 2 ) communicate with the perforations (70) of the outer tube cover (7); a gas block plug (15), It is disposed in the outer tube (12), and forms a sealed air chamber (16) with the shaft center (2), and the through hole (22) of the shaft center (2) communicates with the sealed air chamber (16). ; a nozzle (6), which is placed in the outer tube cover (?) perforation (70) • in the 'outer tube cover (7) Axial holes (2) of the through-hole (22) formed in communication. The above-mentioned DU bearing (5) refers to an oil-free self-lubricating bearing which is a bearing which is made of iron gas dragon and the low frictional property of the metal and the strength and dimensional stability of the metal material. A 〇-shaped ring (8) is disposed on the inner wall surface of the outer tube cover (7), and the ploughshare (8) abuts against the outer wall surface of the outer tube (1 2 ). On the inner wall of the bottom end of the 夕 营 camp f Ί D, 、, 丄 2), an X-ring (9) or 0 'M320527 ring is provided, and the X-ring (9) or the 〇-shaped ring can abut against the shaft (2 ) the outer wall surface. A 〇-shaped ring (丄〇) is disposed on the outer wall surface of the top edge of the shaft (2), the 〇-shaped ring (10) abuts against the inner wall surface of the outer tube (i 2 ), and the periphery of the top end of the shaft center (2) A sliding bearing (1 1 ) is provided, and the sliding bearing (Work 1) abuts against the inner wall surface of the outer tube (12). The sliding bearing (i-work) provided at the periphery of the top end of the shaft (2) forms an octagonal shape, and the outer tube (12) has an octagonal hole shape and is sleeved with the sliding bearing (1 1 ) to make the outer sleeve The tube (丄2) can be restricted from being displaced up and down on the surface of the shaft (2) without arbitrarily deflecting the angle. A 〇-shaped ring (13) is arranged on the outer wall surface of the gas blocker (15), and the gas blocker (15) is disposed in the outer tube (丄2), and is screwed and positioned by the hexagonal countersunk head screw (1 4 ).
