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 the falling process, the bicycles will easily collide with the bars of adjacent bicycles, causing the bars of adjacent bicycles to collide with each other. Bending, even breaking, wheel deformation
Some people, due to personal quality problems, will step on other people's bicycles when pulling their bicycles out of multiple twisted bicycles, causing devastating damage to the fallen bicycles next to them

[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 fastening the windproof and preventing the bicycle fender from being pushed down. 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 the 201 quick release wrench and the 208 set screw , by turning the 201 quick release wrench, when the 201 quick release wrench is in the open state, the cam is in the state of the smallest diameter, the quick release screw cap, 203 first metal gasket, 204 elastic gasket, 205 first fixed block, 206 There is a gap among the second fixing block, the second metal washer 207 and the fixing screw 208.

[0037] When the 201 quick release wrench is in the closed state, the cam is in the state with the largest diameter, and the 201 quick rele...

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

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

[0042] Then, adjust the deflection angle of the 205 first fixed block through the screw cap on the 102 rear wheel central axis screw.

[0043]Then, snap the 202 wrench screw caps into the two round holes on the top of the 201 quick release wrench.

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

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

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

[0047] Finally, rotate the 210 fender to a suitable angle, and rotate the 201 quick release wrench to fix it, thus completing the installation.

no. 3 example

[0049] Such as Figure 3-Figure 8 , when the wind blows, first, put down the bike kickstand.

[0050] Then, rotate the 201 quick release wrench so that the 201 quick release wrench is in the open state, the quick release screw cap, 203 first metal gasket, 204 elastic gasket, 205 first fixed block, 206 second fixed block, 207 second metal pad There is a gap between the sheet and the 208 setscrew.

[0051] Then, the 210 fenders are rotated down so that the 210 fenders are in contact with the ground.

[0052] Then, rotate the 201 quick-release wrench so that the 201 quick-release wrench is in the closed state, and the 201 quick-release wrench and the 208 fixing screw connect the 203 first metal gasket, 204 elastic gasket, 205 first fixed block, 206 second fixed block and 207 The second metal gaskets are tightly fixed together, so as to realize the conversion of functions, from the bicycle fender to the quick conversion of the function of the bicycle foot support bracket.

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.

Description

technical field [0001] The invention relates to the technical field of bicycle parts, in particular to a windproof and overturn-proof bicycle fender. Background technique [0002] When riding a bicycle on a rainy day or on a driveway that has been rained, when the front and rear wheels of the bicycle are rotating, the rear wheels can easily splash the sewage or sand on the driveway onto the rider's clothes, while the front wheels will Sewage splashes to passers-by ahead, in order to avoid the generation of this situation, the rear wheel of bicycle can be provided with a fender usually, avoids muddy water from splashing to cyclist or passer-by with this. [0003] The current common bicycle fender is usually combined with the vehicle frame or the seat frame, and a fender is fixed on the vehicle frame or the seat frame, so as to prevent the sewage or sludge from the driveway from splashing on the cyclist or passers-by. [0004] The current bicycle fender has a single function,...
