Front, opening: ΐ: Figure 2 and Figure 3 'In order to prevent the dust jacket 1 from being lost after being assembled in = Deformation or prevention of the appearance of deformation of the boot 1 during the front avoidance of the TO operation, the boot 1 will have the structure of the vent 11 . Here, as shown in Fig. 3, the vent 11 is formed on the bottom of the dustproof 1 And the vent hole u is connected between the L gas C 12 and the outside large rolling in one of the dust jackets. As described above, in the case where air can flow between the air passage 12 and the outside atmosphere in the dust jacket 1 , the appearance of deformation of the dust jacket! can be avoided. However, although the appearance of the deformation of the dust jacket 1 can be avoided due to the presence of the vent hole 11, a small amount of sand and moisture can still be formed into the dust jacket 1 The vent hole U on the bottom of the bottom invades the front shock absorber M1, thus causing front shock absorber The device M1 is damaged after a period of use. SUMMARY OF THE INVENTION The present invention basically adopts the features as detailed below in order to solve the above problems. That is, the present invention includes a dust cover body and has an inner portion. An air passage; and a curved vent tube is coupled to the dust jacket body and communicated with the service rail, such that the inner air passage of the dust cover body communicates with the outside atmosphere. ^ At the same time, the shock absorber according to the present invention a dust jacket structure having a substantially L-shaped shape. In the present invention, the squirting snorkel is integrally formed with the dust jacket system. The above objects and features of the present invention are The advantages of the present invention will be described in detail with reference to the accompanying drawings. FIG. The shock absorber dust jacket structure 1 is sleeved on a locomotive Μ before the shock absorber M1. As shown in Figures 5, 6 and 7, the shock absorber boot Structure 100 main package There is a boot body n〇 and a curved vent tube 12〇. As shown in Figures 6 and 7, the boot body ho has an inner air passage 111. Before the 'locomotive Μ, the shock absorber M1 is sleeved on In the inner airway 111.
彎曲通氣管〗20是連接於防塵套本體11〇，並且彎曲 通氣管120是連通於防塵套本體1]()之内通氣道ηι，其 可用來使防塵套本體110之内通氣道】1】連通於外界大 氣。如上所述，在空氣可於防塵套本體之内通氣道1U 201213185 與外界大氣之間流通的情況下，防塵套本體110之外觀變 形的現象可以被避免。此外，在本實施例之中，彎曲通氣 管120具有一大致上為L形之形狀。特別的是，如第4圖 所示’當整個避震器防塵套結構100套設於前避震器mi 之上時，大致上為L形之彎曲通氣管12〇的一開口 121乃 是朝向地面。 此外，就彎曲通氣管120與防塵套本體11〇之間的連 接或結合方式而言，避震器防塵套結構1〇〇亦可以選擇性 採用一體成型之彎曲通氣管12〇與防塵套本體η。。 如上所述，由於避震器防塵套結構1〇〇具有大致上為 L形之彎曲通氣管120，並且彎曲通氣管12〇之開口 Η】 在避震器防塵套結構1〇〇套設於前避震器M1之上後乃是 朝向地面，故外界沙土及水份經由彎曲通氣管12〇入侵= 前避震器Ml上的機會已更為降低。因此’前避震器％】 之使用壽命可以被更為延長。 雖然本發明已以較佳實施例揭露於上’然其並非用以 限定本發明’任何熟習此項技藝者，在不脫離本發明之精 神和範圍内，當可作些許之更動與潤飾，因此本發明之保 護範圍當視後附之申請專利範圍所界定者為準。 201213185 【圖式簡單說明】 =:係顯示一種習知之防塵套之應用狀態示意圖； J2圖係顯示習知之防塵套之側視示意圖； :3圖係顯，習知之防塵套之仰視示意圖； 一立国. 、乃之避震器防塵套結構之應用狀態 不思園，The curved vent tube 20 is connected to the dust jacket body 11 〇, and the curved vent tube 120 is connected to the air passage ηι inside the dust jacket body 1] (), which can be used to make the air passage inside the dust jacket body 110] Connected to the outside atmosphere. As described above, in the case where air can flow between the air passage 1U 201213185 and the outside atmosphere in the body of the boot, the appearance of the outer shape of the boot body 110 can be prevented. Further, in the present embodiment, the curved vent 120 has a substantially L-shaped shape. In particular, as shown in FIG. 4, when the entire shock absorber boot structure 100 is sleeved over the front shock absorber mi, an opening 121 of the substantially L-shaped curved vent tube 12 is oriented ground. In addition, in terms of the connection or combination between the curved vent tube 120 and the boot body 11 ,, the shock absorber boot structure 1 选择性 can also selectively adopt the integrally formed curved vent tube 12 〇 and the boot body η . . As described above, since the shock absorber boot structure 1 has a substantially L-shaped curved vent pipe 120, and the curved vent pipe 12 〇 opening Η] is placed in front of the shock absorber boot structure 1〇〇 After the shock absorber M1 is above the ground, the outside sand and water invade through the curved snorkel 12 = = the chance of the front shock absorber M1 has been reduced. Therefore, the service life of the 'front shock absorber%' can be extended. Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the invention, and may be modified and modified, without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims. 201213185 [Simple description of the diagram] =: shows a schematic diagram of the application state of a conventional dust jacket; J2 diagram shows a side view of a conventional dust jacket; 3 diagram shows the schematic view of a conventional dust jacket; , the application status of the shock absorber dust cover structure is not thinking about the park,
