DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-6 , an embodiment provided by the utility model:

[0024] A dust cover for a car shock absorber, comprising:

[0025] The device body includes a car shock absorber dust cover body 100 and a corrugated tube 112:

[0026] The top and bottom of the automobile shock absorber dust cover body 100 are respectively provided with an upper cover 110 and a lower cover 111. The peripheral side wall of the corrugated tube 112 is composed of a concave portion 113 and a convex portion 114 which are alternately distributed in concave and convex forms. The inner diameter of the convex portion 114 is larger than the maximum outer diameter of the automobile shock absorber. A limiting protrusion 116 is fixedly installed on one side of the inner part of the corrugated tube 112, and the limiting protrusion 116 is T-shaped. Both sides of the limiting protrusion 116 are connected to the corrugated tube 112 through a mother-and-child sticker. A limiting through hole 116 matching the limiting protrusion 116 is opened on the other side of the corrugated tube 112. 5. There are three limiting through holes 115. Fixing devices 128 are respectively provided on the upper cover 110 and the lower cover 111. Fixing hoops 117 are sleeved on the upper cover 110 and the lower cover 111 to allow the bolt 119 to pass through the two connecting blocks 118. The hexagonal nut 120 is screwed on the protruding end of the bolt 119 to lock or disassemble it. Then, the limiting protrusions 116 are pressed into the limiting through holes 115 in sequence. Since the limiting protrusions 116 are T-shaped and connected with a mother-and-child sticker, debris is prevented from entering the side. At the same time, the setting of the fixing device 128 does not require tools.

[0027] Furthermore, the fixing device 128 includes a fixing hoop 117. The outer sides of the upper cover 110 and the lower cover 111 are sleeved with the fixing hoop 117. The ends of the fixing hoop 117 are fixedly installed with a connecting block 118. The connecting block 118 is penetrated through the interior of the connecting block 118 by bolts 119. The protruding ends on both sides of the connecting block 118 are installed with regular hexagonal nuts 120 by threaded engagement, and the regular hexagonal nuts 120 are provided with anti-slip grooves.

[0028] Furthermore, a shock-absorbing rod hole 121 is provided at the center of the top of the upper cover 110 .

[0029] Furthermore, a first filter 122 is disposed on the upper cover 110 , and the first filter 122 is provided to prevent dust from entering the upper cover 110 when the upper cover 110 is replaced.

[0030] Furthermore, a second filter screen 123 is disposed on the top of the inner wall of the upper cover 110 . The number of the second filter screens 123 is four. The second filter screens 123 are provided to dissipate heat inside the automobile shock absorber dust cover body 100 when it is working.

[0031] Furthermore, the corrugated tube 112 is composed of a natural rubber layer 124, a silicone layer 125, a sound-absorbing cotton layer 126 and a wear protection layer 127, and the silicone layer 125 is bonded to the inner side of the natural rubber layer 124, and the sound-absorbing cotton layer 126 is provided on the side of the silicone layer 125 away from the natural rubber layer 124, and the wear protection layer 127 is bonded on the side of the sound-absorbing cotton layer 126 away from the silicone layer 125. The natural rubber layer 124 and the silicone layer 125 cooperate with each other to improve the noise reduction performance of the sound-absorbing cotton layer 126, and the provision of the wear protection layer 127 extends the service life of the corrugated tube 112.

[0032] Working principle: When in use, a fixing hoop 117 is sleeved on the upper cover 110 and the lower cover 111, so that the bolt 119 passes through the two connecting blocks 118, and the hexagonal nut 120 is threadedly screwed on the protruding end of the bolt 119 to lock or disassemble it, and then the limiting protrusion 116 is pressed into the limiting through hole 115 in sequence. Since the limiting protrusion 116 is T-shaped and connected with a mother-and-child sticker, it prevents debris from entering from the side. At the same time, the setting of the fixing device 128 does not require tools. The natural rubber layer 124 and the silicone layer 125 are used in conjunction with each other, so that the sound-absorbing cotton layer 126 can improve its noise reduction performance, and the setting of the wear protection layer 127 extends the service life of the corrugated tube 112.
