Detailed Description

the present invention will be further described with reference to the accompanying drawings.

a bicycle front mudguard mounting structure is shown in figures 1 and 2 and comprises a front mudguard 1, wherein the front mudguard 1 comprises a front baffle 11 and a rear baffle 12, a step 13 is arranged between the front baffle 11 and the rear baffle 12, the front baffle 11 is higher than the rear baffle 12, a connecting seat 2 is integrally formed on the upper surface of the rear baffle 12, a plurality of reinforcing ribs 21 are arranged on the side wall of the connecting seat 2, and the reinforcing ribs 21 can enhance the structural strength of a joint surface between the connecting seat 2 and the rear baffle 12 and avoid deformation to a certain extent; the top of the connecting seat 2 is provided with an opening, the side wall of one end of the connecting seat 2, which is far away from the step 13, is provided with an inserting port 22, a plurality of first clamping teeth 23 are arranged on the inner side wall of the connecting seat 2, which is adjacent to two sides of the inserting port 22, and the first clamping teeth 23 are vertically arranged; the rear end baffle 12 is further provided with a guide block 3 positioned in the connecting seat 2, a sliding groove 24 is formed between the guide block 3 and the inner wall of the connecting seat 2, and one end of the guide block 3 close to the insertion port 22 is provided with a guide surface 31.

As shown in fig. 1, 2 and 3, the connector further comprises a connector 4 in plug-in fit with the connector base 2, the connector 4 comprises a top plate 41 and a bottom slider 42 which are arranged in parallel, the bottom slider 42 can be in sliding fit along a sliding groove 24, an elastic clamping block 5 is arranged between the top plate 41 and the bottom slider 42, the elastic clamping block 5 is located on two sides of the connector 4, a gap 6 is arranged between the elastic clamping block 5 and the top plate 41 as well as between the elastic clamping block 42 and the bottom slider 42, stop blocks 25 are symmetrically arranged on the inner side wall of the connector base 2, and the stop blocks 25 extend into the gap 6 between the elastic clamping; a through hole 411 is formed in a top plate 41 of the connector 4, a bolt 7 is connected to the through hole 411 in a threaded manner, a positioning sleeve 8 is sleeved on the outer wall of the bolt 7 extending out of the connector 4, a rotation stopping hole 81 is formed in the bottom of the positioning sleeve 8, a rotation stopping block 412 matched with the rotation stopping hole 81 in a rotation stopping manner is arranged on the top plate 41, the through hole 411 penetrates through the rotation stopping block 412, and a U-shaped positioning hole 82 is formed in the side wall of the positioning sleeve 8 along the axial direction of the positioning sleeve 8; the outer wall of the elastic fixture block 5 is provided with a plurality of second latch teeth 51, and the second latch teeth 51 are in positioning fit with the first latch teeth 23 after being mutually inserted.

In the installation process, insert the position sleeve 8 to the frame along the axial earlier, the lug in the frame inserts and to restrict position sleeve 8 circumferential direction in the locating hole 82 and rotate, penetrate bolt 7 in the through-hole 411 again, can be with connector 4 fixed connection on the bicycle frame through bolt 7, because between connector 4 and the position sleeve 8 through the cooperation of splines hole 81 and the spline piece 412 splines, so connector 4 is difficult for taking place to rotate when bolt 7 twists in the frame, and the locate effect is better. When connecting connector 4 and connecting seat 2 link to each other, pull elasticity fixture block 5 to connector 4 in with the hand, insert connector 4 front end to connecting seat 2 in from interface 22 of connecting seat 2 again, when connector 4 inserts in connecting seat 2, footing slider 42 inlays in sliding in connecting seat 2 behind spout 24, and guide block 3 and guide surface 31 can play the guide effect to connector 4 when sliding, make connector 4 and connecting seat 2 high-speed joint. After the elastic clamping block 5 is loosened, the elastic clamping block 5 moves towards the direction close to the inner wall of the connecting seat 2 under the action of the elasticity of the elastic clamping block 5, and finally the first clamping tooth 23 is buckled with the second clamping tooth 51, so that the connecting head 4 and the connecting seat 2 can be positioned along the horizontal direction, and the connecting head 4 can be positioned along the vertical direction with the connecting seat 2 because the connecting head 4 is inserted into the connecting seat 2 and the rear stop block 25 is inserted into the gap 6 and is propped against the upper surface of the elastic clamping block 5. When the current mud board 1 damages the back and needs to be changed, as long as pull elasticity fixture block 5 in to connector 4, make first latch 23 break away from with second latch 51, slide connecting seat 2 along the axial to the direction of keeping away from connector 4, can dismantle preceding mud board 1 from connector 4. So, it is convenient when not only installing, dismantling preceding mud board 1, and the relative position is difficult for taking place to deviate after connector 4 and the 2 lock of connecting seat moreover, and in addition, the installation is also more firm.

because the gap 6 is arranged between the elastic fixture block 5 and the top plate 41 and between the elastic fixture block 5 and the bottom foot slider 42, sliding friction does not exist when the elastic fixture block 5 is pulled towards the inside of the connector 4, on one hand, the abrasion of the elastic fixture block 5 can be reduced, and on the other hand, the pulling process can be more labor-saving.

As shown in fig. 2, the tail portions of the two elastic fixture blocks 5 extend to form holding portions 52, the holding portions 52 extend out of the insertion port 22, the two symmetrical holding portions 52 are arranged in a flaring shape, and the holding portions 52 are provided with anti-slip patterns 521. The two symmetrical holding parts 52 are arranged in a flaring shape, when the two holding parts are pulled in opposite directions, a user can pull the elastic fixture block 5 with slight force, so that the effect of saving labor is achieved, and in addition, the anti-skid grains 521 can play a role of anti-skid to a certain extent.

The above is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the claims of the present invention.
