Problems solved by technology

[0007] When the wind blows, we can often see bicycles in various inverted postures on the street. When the bicycle falls down, it is easy to break down, which will deform the relatively fragile parts of the body, rub the paint between the body and the ground, and stain it with mud. In severe cases, the bicycles parked in a row will fall together, and multiple bicycles will be twisted together. During ...

Method used

As shown in Fig. 1-Fig. 3, the top of 201 quick release wrench is equivalent to a cam structure, relies on the rotation of 201 quick release wrench to reach the purpose of fastening windproof, anti-pull down bicycle fender. When the 203 first metal gasket, 204 elastic gasket, 205 first fixed block, 206 second fixed block and 207 second metal gasket are fixed between the quick release screw cap on ...

Abstract

The invention discloses a wind-proof mud guard capable of preventing a bicycle from being pushed over. Quick switching from a bicycle mud guard function to a bicycle kickstand support function is achieved according to rotation of a quick release spanner, when being supported, the mud guard is used for preventing sewage or sludge from splashing in the riding process, when being put down, the mud guard is used for supporting a bicycle body and equivalent to a bicycle kickstand support, the contact area of the bicycle and the ground surface is enlarged, and the bicycle is prevented from being pushed over by strong wind. According to the wind-proof mud guard capable of preventing the bicycle from being pushed over, the purposes that the mud guard can resist wind tightly, and the mud guard canprevent the bicycle from being pushed over are achieved according to a cam structure at the top end of the quick release spanner, when the quick release spanner is in an opened state, a cam is in thestate that the diameter is the smallest, and the position of the mud guard can be adjusted; and the quick release spanner is in a closed state, the cam is in the state that the diameter is the largest, the position of the mud guard can be fixed, the structure is simple, and the wind-proof mud guard is easy to achieve and popularize.

Example

[0035] First embodiment

[0036] Such as Figure 1-Figure 3 , The top of the 201 quick release wrench is equivalent to a cam structure, relying on the rotation of the 201 quick release wrench to achieve the purpose of tightening wind and preventing the bicycle fender from falling down. When fixing the 203 first metal washer, 204 elastic washer, 205 first fixing block, 206 second fixing block and 207 second metal washer between the quick-release screw cap on the 201 quick-release wrench and the 208 fixing screw , By turning the 201 quick-release wrench, when the 201 quick-release wrench is open, the cam is in the smallest diameter state, the quick-release screw cap, 203 first metal washer, 204 elastic washer, 205 first fixed block, 206 There is a gap between the second fixing block, the second metal gasket 207 and the fixing screw 208.

[0037] When the 201 quick-release wrench is in the closed state, the cam is in the largest diameter state. The 201 quick-release wrench and 208 fixing screws connect 203 the first metal washer, 204 elastic washer, 205 the first fixing block, and 206 the second fixing block. It is tightly fixed with the second metal gasket of 207, so that through the rotation of the 201 quick release wrench, the purpose of tightening the wind and preventing the bicycle fender is achieved.

[0038] The left side of the 204 elastic gasket is in contact with the right side of the 203 first metal gasket, and the right side is in contact with the left side of the 205 first fixed block. The center of the 204 elastic gasket has a round hole. When the 201 quick release wrench is rotated , 204 elastic gasket undergoes a certain deformation under pressure, and then is compressed, so that the second fixing block 206 is tightly fixed between the 208 fixing screw and the 202 wrench screw cap.

Example

[0039] Second embodiment

[0040] Installation steps: such as Figure 1-Figure 3.

[0041] First, fix the 205 first fixing block on the 102 rear axle screw.

[0042] Then, the deflection angle of the first fixing block 205 is adjusted by the screw cap on the center shaft screw of the rear wheel 102.

[0043] Then, clip the screw cap of wrench 202 into the two round holes on the top of the wrench 201.

[0044] Then, use 208 fixing screws to string together 207 second metal gasket, 206 second fixing block, 205 first fixing block, 204 elastic gasket and 203 first metal gasket from right to left.

[0045] Then, screw the leftmost end of the 208 fixing screw into the 202 wrench screw cap.

[0046] Then, fine-tune the tightness between the 208 fixing screw and the 202 wrench screw cap.

[0047] Finally, rotate the 210 mudguard to an appropriate angle, and rotate the 201 quick release wrench to fix it to complete the installation.

Example

[0048] The third embodiment

[0049] Such as Figure 3-Figure 8 When it is windy, first, put down the bicycle foot support.

[0050] Then, turn the 201 quick release wrench to open the 201 quick release wrench, the quick release screw cap, 203 first metal washer, 204 elastic washer, 205 first fixing block, 206 second fixing block, and 207 second metal pad There is a gap between the sheet and the 208 fixing screw.

[0051] Then, rotate the 210 fender and put it down so that the 210 fender is in contact with the ground.

[0052] Then, turn the 201 quick-release wrench to close the 201 quick-release wrench. The 201 quick-release wrench and the 208 fixing screw connect the 203 first metal gasket, 204 elastic gasket, 205 first fixing block, 206 second fixing block and 207 The second metal spacers are tightly fixed together, so as to realize the function conversion, from the bicycle mudguard to the bicycle foot support bracket.
