[0028] It should be understood that throughout the drawings, like reference numerals represent like elements. The terms used in this specification are intended only to describe specific embodiments and are not intended to limit the present disclosure. Unless otherwise defined, all terms (including technical and scientific terms) used in this specification have the meanings commonly understood by those skilled in the art. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0029] The dust cover 100 according to an embodiment of the present disclosure will be described below.

[0030] The dust cover 100 according to the embodiment of the present disclosure is installed on the fork 200 and is configured to cover the sliding member and can be Figure 3 ) and stretched state ( Figure 4 ). When the slider 221 of the fork 200 is within the slide rail 211, the dust cover 100 is in the retracted state. When the slider 221 of the fork 200 slides beyond the slide rail 211, the dust cover 100 is in the extended state. For ease of description, the direction in which the dust cover moves from the retracted state to the extended state is referred to as the outward direction, and the direction in which the dust cover moves from the extended state to the retracted state is referred to as the inward direction.

[0031] The dust cover 100 includes a bracket 110 and a cover body 120. The bracket 110 is fixed to the main body 210 of the fork 200 and fixed relative to the slide rail 211. Figure 5As shown, the bracket 110 includes a base 111 that is substantially planar. An opening 112 having a shape and size corresponding to the slide rail 211 is provided at the center of the base 111. A first protrusion 113, a second protrusion 114, a third protrusion 115, and a fourth protrusion 116 are provided on the four sides of the base 111, respectively, protruding from the base 111 in a direction perpendicular to the base 111. Figure 5 As shown, the first protrusion 113 is located on the left side of the base 111, the second protrusion 114 is located on the upper side of the base 111, the third protrusion 115 is located on the right side of the base 111, and the fourth protrusion 116 is located on the lower side of the base 111. The second protrusion 114, the third protrusion 115, and the fourth protrusion 116 are all generally L-shaped, respectively having stoppers 1141, 1151, and 1161 that are generally parallel to the base 111. The first protrusion 113 is strip-shaped. The protruding height h1 of the first protrusion 113 is lower than the protruding height h2 of the second protrusion 114, the third protrusion 115, and the fourth protrusion 116.

[0032] Figure 6 This is a perspective view of the cover 120 as viewed from the outside. Figure 6 As shown, the cover body 120 is configured to cover the sliding member 221 and is generally bellows-shaped, including a plurality of cover plates 121, an outer plate 125, and a flexible cover 124. The cover plates 121 and the outer plate 125 are generally rigid and have approximately equal outer dimensions. The outer dimensions of the cover plates 121 and the outer plate 125 are slightly smaller than the dimensions of the bracket 110, so that the cover plates 121 and the outer plate 125 can be smoothly placed on the bracket 110 during the installation process. The flexible cover 124 connects and covers the periphery of the cover plates 121 and the outer plate 125, so that the cover body 120 is integrated. Since the cover 124 is flexible, the cover body 120 can be in a contracted state ( Figure 3 ) and stretched state ( Figure 4 ) between the cover plate 121 on one side ( Figure 6 A recess is provided (on the right side in the figure), at which a flexible cover 122 is provided. The cover 122 is connected to the outer panel 125 but not to the cover panel 121, and is movable between an open position and a closed position in a manner similar to a door. In the open position, the cover 122 exposes the recess, and in the closed position, the cover 122 covers the recess.

[0033] Figure 8 1 is a perspective view of the cover 120 from the inside, with the bolts 130 and nuts 131 removed. Figure 8 As shown, a hole 123 is provided in the center of the outer plate 125 , and a cover plate opening 126 corresponding to the opening 112 of the bracket 110 is provided on the cover plate 125 .

[0034] Figure 7The cover 120 is a perspective view from the inside. The bolts 130 for mounting the cover 120 can be inserted through the holes 123 of the outer plate 125 so that the heads of the bolts 130 abut against the outer surface of the outer plate 125 ( Figure 6 After the screw rod of the bolt 130 is inserted into the hole 123, the nut 131 can be screwed onto the screw rod of the bolt 130 from the inside and abut against the inner surface of the outer plate 125. Preferably, the nut 131 is a non-slip nut.

[0035] Refer to the following Figures 9 to 15 The following describes a process for mounting the dust cover 100 on the fork 200 .

[0036] like Figure 9 As shown, a threaded hole 223 is drilled on the outer surface of the sliding member 221. Next, as shown in FIG. Figure 10 As shown, the mounting stud 140 is mounted to the outer surface of the sliding member 221. Figure 15 As shown, the mounting stud 140 includes a mounting screw 142 on one side and a mounting screw hole 141 on the other side. The mounting screw 142 is provided with an external thread corresponding to the threaded hole 223. The mounting screw hole 141 is provided with an internal thread corresponding to the screw of the bolt 130. The mounting screw 142 of the mounting stud 140 is screwed into the threaded hole 223, thereby fixing the mounting stud 140 to the sliding member 221. At this time, the length l1 of the mounting stud 140 protruding from the sliding member 221 is less than the length l2 of the cover 122 in the sliding direction ( Figure 12 ).

[0037] Next, the bracket 110 is fixed to the main body 210 with an adhesive so that the opening 112 of the bracket 110 corresponds to the slide rail 211, that is, the sliding member 221 is located in the opening 112. Figure 11 shown.

[0038] After the bracket 110 is fixed to the main body 210, the cover body 120 is inserted from the side of the first protrusion 113 so that one or more innermost cover plates 121 of the cover body 120 are located inside the stoppers 1141 and 1161. Figure 12 and Figure 13 As shown in FIG. Because the first protrusion 113 is not provided with a stopper and the height h1 of the first protrusion 113 protruding from the base 111 is less than the height h2 of the second protrusion 114, the third protrusion 115, and the fourth protrusion 116, the cover 120 can be inserted by translation from the side of the first protrusion 113, ultimately positioning the cover 120 against the stops 1141, 1151, and 1161. Because the openable and closable cover 122 is provided and the length l1 of the mounting stud 140 protruding from the slider 221 is less than the length l2 of the cover 122 in the sliding direction, the mounting stud 140 does not hinder the insertion of the cover 120 during the insertion process.

[0039] After the cover 120 is positioned against the stoppers 1141, 1151, and 1161, the nut 131 is placed on the inner side of the outer plate 125 with the cover 122 in the open position, the screw rod of the bolt 130 is inserted through the hole 123 of the outer plate 125 into the nut 131, and the nut 131 is tightened on the screw rod so that the screw rod of the bolt 130 abuts against the outer surface of the outer plate 125 and the nut 131 abuts against the inner surface of the outer plate 125, that is, the bolt 130 and the nut 131 are fixed to the outer plate 125. Next, the screw rod of the bolt 130 is inserted into the mounting screw hole 141 of the mounting stud 140 and tightened, thereby fixing the screw rod in the mounting screw hole 141, completing the installation of the cover 120. Figure 14 During this process, since the innermost one or more cover plates 121 of the cover body 120 are restricted by the stoppers 1141, 1151 and 1161, the cover body 120 is roughly positioned on the bracket 110, and there is no need to worry about the cover body 120 being loosened, which facilitates the installation process.

[0040] The operation of the dust cover 100 will be described below.

[0041] After the dust cover 100 is mounted on the fork 200, the dust cover 100 is in Figure 3 When the sliding member 221 of the fork 200 slides outward along the slide rail 211, since the bolt 130 and the nut 131 are fixed on the outer plate 125, and the screw rod of the bolt 130 is fixed in the mounting screw hole 141 of the mounting stud 140, and the mounting stud 140 is fixed in the threaded hole 223 on the sliding member 221, the outer plate 125 of the cover body 120 moves outward as the sliding member 221 slides outward, driving the cover plate 121 and the flexible cover 124 to move outward, so that the dust cover 100 is moved outward. Figure 3 The contracted state shown is Figure 4 Move in the extended state shown.

[0042] When the dust cover 100 is in the extended state, if the sliding member 221 slides inward, the dust cover 100 is also extended from the inner side by the force transmission between the bolt 130 and the mounting stud 140. Figure 4 The extended state shown Figure 3 Move in the contracted state shown.

[0043] Here, as long as the difference between the length of the dust cover 100 in the fully extended state and the length in the retracted state is set to be greater than the maximum sliding stroke of the slider 221, it can be ensured that the dust cover 100 can smoothly extend and retract following the sliding of the slider 221.

[0044] The dust cover structure described above can provide an effective barrier during the sliding operation of the slider 221, preventing smoke, smoke dust, and other small particles from entering the interior of the slide rail 211. In addition, the dust cover disclosed in the present invention can also adapt to the expansion and contraction and vibration of the slider 221 during operation, ensuring an optimal sliding state and improving work efficiency.

[0045] The embodiments of the present disclosure are described above, but it should be understood that the present disclosure is not limited thereto. A person skilled in the art may conceive of various modifications without departing from the scope of the present disclosure.

[0046] For example, in the embodiment described above, the cover 120 is rigidly connected to the slider 221 via bolts 130 and mounting studs 140 to facilitate expansion and contraction of the cover. However, it is contemplated that these rigid connections could be omitted. In such a case, a resilient cover could be employed instead of a flexible cover, allowing the cover to contract inwardly to a contracted state when no force is applied, and to transition to an extended state when the slider 221 slides outward under force.

[0047] For example, in the embodiment described above, a plurality of stoppers are provided on the bracket 110 to position the cover 120. However, it is conceivable that there may be one or more stoppers, or that the stoppers may be omitted and the innermost one or more cover plates 121 of the cover 120 may be positioned on the bracket 110 using other methods (e.g., gluing, etc.).

[0048] For example, in the embodiments described above, the shapes of the bracket and the cover are designed. However, it is conceivable that these shapes are not restrictive and can be flexibly changed according to the shapes of the slide rail and the sliding member.

[0049] For example, in the embodiment described above, the mounting stud 140 is provided with a mounting screw on one side that is screwed into the threaded hole 223. However, it is conceivable that the mounting stud is not provided with a mounting screw, but is fixed to the sliding member 221 by other means (such as gluing, etc.).

[0050] For example, in the embodiment described above, the dust cover is described with reference to a fork as an example. However, it is conceivable that the dust cover can be used for other equipment that performs sliding operations.

[0051] It will be understood by those skilled in the art that various changes and modifications may be made to the exemplary embodiments of the present disclosure without departing substantially from the spirit and scope of the present disclosure. Therefore, all such changes and modifications are intended to be included within the scope of the present disclosure as defined by the appended claims. The present disclosure is defined by the appended claims, and equivalents of these claims are intended to be included therein.
