Description

  The present invention relates to a mudguard structure, and more particularly to a mudguard rapid desorption structure provided on a front fork of a bicycle.

  In order to pursue environmental conservation and health, the bicycle industry has been actively developed. Modern bicycles have a variety of accessories, such as mudguards. Basically, these accessories can be quickly attached to and detached from the bicycle according to the needs of the user.

  Please refer to FIG. 1 and FIG. FIG. 1 and FIG. 2 show a “detachable bicycle front fork accessory coupling device” of Patent Document 1 proposed by the applicant of the present application. The front fork pressing structure B is coupled to the end of the front fork A of the bicycle, and the quick detaching structure C is assembled to the bottom of the front fork pressing structure B. The mudguard D can be quickly detached from the front fork A by the rapid desorption structure C. As shown in FIG. 1, an assembling table D1 having a circular shape is provided on the surface of the mudguard D, and four arc-shaped grooves D2 are provided on the end surface of the assembling table D1, and these arc-shaped grooves D2 are One end is formed into the groove wall D21 and the other end is formed into the opening D22.

  FIG. 2 is a cross-sectional view showing a combined state of a conventional mudguard and its fixing structure. The rapid desorption structure C has a control tool 10. The control tool 10 is formed with a base portion 101 and a handle portion 102. A disk 11 is provided above the base part 101. An annular end surface 111 is formed around the disk 11. A pressing edge A <b> 1 at the end of the front fork A is in contact with the annular end surface 111. A coupler 12 is provided below the base portion 101. Four locking blocks 103 are provided on the peripheral surface of the coupler 12. The locking block 103 is molded along the circumferential direction and has an L-shaped cross-sectional shape. A sink hole 121 is provided at the center of the lower surface of the coupler 12. When the fastener 13 is inserted through the sink hole 121 of the coupler 12 and the base portion 101 of the controller 10 and the disk 11 sequentially and fastened to the front fork compression structure B, the front fork compression structure B is connected to the front fork A. Combined. In this way, by inserting the four locking blocks 103 of the control tool 10 into the four arc-shaped grooves D2 of the mudguard D and inserting the ends of the locking blocks 103 into the openings D22 of the arc-shaped grooves D2. The mudguard D can be fixed to the front fork A.

  However, the base part 102 is locked with the mudguard D or detached from the mudguard D by pulling the handle part 101 of the control tool 10 and the assembly structure of the conventional quick desorption structure C and the front fork tightening structure B. The operating method has the following drawbacks.

  (1) Since the control tool 10 is locked with the mudguard D by turning the platform 102 and actually operated, the user cannot easily determine the position of the locking block 103 from above the control tool 10. The arcuate groove D2 of the mudguard D is tried so as to correspond to the locking block 103, and the control tool 10 is pulled to lock the both. However, when the control tool 10 is turned, the position corresponding to the tire of the bicycle of the mudguard D is affected. Thus, after the mudguard D is fixed, the handle 102 of the control tool 10 is pulled and the position of the mudguard D is not corrected. And the mudguard effect is not good.

  (2) Although the quick desorption structure C is assembled to the mudguard D by the turning method, both locking structures are located above the turning direction, so that if the user applies too much force to the both, the locking structure or the control tool There is a possibility that the ten handle portions 102 may be damaged.

  (3) Since the rapid desorption structure C is operated by turning the control tool 10, the disk 11 and the coupling tool 12 are used to avoid wear of the front fork A and the mudguard D during the turning process of the control tool 10. It is necessary to provide it. If it does so, a structure will become complicated, an assembly work will become inconvenient, and production cost will increase.
