In view of the above-mentioned problems of the prior art, the object of the present invention is to provide a coupling mechanism for solving the problem that when the bicycle auxiliary wheel is coupled to the bicycle because the connecting mechanism is fixed, the rider cannot use the bicycle when riding the bicycle. A problem of progressively swinging the left and right swings to achieve training balance.

According to the purpose of the present invention, a coupling mechanism is provided, including a first rod body, including: a first side wall disposed at one end of the first rod body and forming an accommodating space, and a first one is disposed thereon a perforation, and a first fixing seat is disposed between the other end of the first rod body and the accommodating space; a second rod body having a first thread on the surface thereof and a second perforation at one end thereof, and One end is accommodated in the accommodating space, and the second through hole is corresponding to the first through hole, and is disposed on the first side wall; a cover is sleeved on the second rod body, and a second fixing seat is disposed on one side thereof a spring, the first fixing seat is sleeved at one end, and the second fixing seat is sleeved at the other end; a screw cap is hollow and has a second thread on the inner side surface of the screw cap, and the capping system is The second thread is sleeved on the first thread of the second rod and is disposed on the cover.

In view of the above, the linking mechanism according to the present invention may have one or more of the following advantages:

(1) The connecting mechanism adjusts the length of the spring by rotating the screw cap, and can arbitrarily adjust the angle at which the bicycle leans toward the auxiliary wheel, thereby assisting the child to learn the bicycle in a progressive manner.

(2) The connecting mechanism can completely fix the angle of the auxiliary wheel to the bicycle by screwing the screw cap, and the applicability is very high.

Please refer to FIG. 1 , which is a schematic view of the first explosion of the connecting mechanism of the present invention. As shown in the figure, the connecting mechanism 1 of the present invention comprises a first rod body 10, a second rod body 11, a shutter 12, a spring 13 and a screw cap 14; wherein the first rod body 10 includes the opposite side The first side wall 100 and the first fixing base 101 are opposite to each other, and the first side wall 100 is disposed at one end of the first rod body 10 to form an accommodating space 1000. The accommodating space 1000 has openings 1001 and 1002 respectively. One end and the other end of the first rod body 10, the first side wall 100 is further disposed with a first through hole 1003; the first fixing base 101 is disposed at the other end of the first rod body 10 and the accommodating space. Between 1000, and the first fixing base 101 intersects the first rod body 10 at an oblique angle.

The second rod body 11 has a first thread 110 on its surface, and a second through hole 111 is disposed at one end of the second rod body 11. The second rod body 11 is received at one end thereof in the accommodating space 1000. in. After the second through hole 111 is corresponding to the first through hole 1003, the second rod body 11 is pivoted on the first side wall 100 by a bolt 1004, so that the second rod body 11 can be in the accommodating space 1000 with the bolt 1004. For the shaft center, a limited rotation is provided; the cover 12 is provided with a second fixing base 120 on one side thereof, and is sleeved on the second rod body 11 in a manner that the second fixing base 120 is opposite to the first fixing base 101. on. The first fixing base 101 and the second fixing base 120 may be in the shape of a convex column or may be formed in a groove shape (as shown in FIG. 2). The distance between the second fixing base 120 of the cover 12 and the first fixing base 101 of the first rod 10 determines a limited length. Therefore, when the spring 13 is disposed at one end of the first fixing base 101 and the other end is disposed on the second fixing base 120, the telescopic space of the spring 13 is the limiting length between the first fixing base 101 and the second fixing base 120. The screw cap 14 is disposed on the cover 12, and the screw cap 14 is hollow and has a second thread 140 on the inner side surface thereof, and the screw cap 14 is sleeved on the second rod body 11 by the second thread 140. The first thread 110 allows the user to rotate the screw cap 14 to adjust the distance between the first mount 101 and the second mount 120.

By the connection of the above-mentioned various machine members and their functions, we can adjust the elastic state of the spring 13 by rotating the screw cap 14, and when the spring 13 is restrained to the pressing state, the second rod body 11 cannot When any rotation is performed, it is fixed in the accommodating space 1000; in contrast, when the screw cap 14 is unscrewed upward, the spring 13 starts to have elasticity and can be reciprocally pressed in a limited manner, and the other end of the second rod body 11 is further Limited to the other end of the first rod 10 is inclined.

Please refer to FIG. 3, which is a schematic exploded view of an embodiment of the joint mechanism of the present invention. As shown in the figure, the first rod body 10 further includes a second side wall 102. One end of the second side wall 102 is disposed at the other end of the first rod body 10, and the first rod body 10 and the second side wall 102 are integrated into one another. shape. In addition, the other end of the second side wall 102 is provided with a third through hole 1020 which is provided with a screw 1021 and is coupled to a bicycle auxiliary wheel 2.

The connecting mechanism 1 of the present invention further includes a plate body 15 extending from one end of the plate body 15 to a third side wall 150 of the hollow surrounding shape to join the second rod body 11. The third side wall 150 has a third thread 1500 (as shown in FIG. 4), and the third side wall 150 is sleeved on the first thread 110 of the second rod 11 by the third thread 1500. The method is fixed to the other end of the second rod body 11. Further, the plate body 15 may be manufactured integrally with the second rod body 11 and provided at the other end of the second rod body 11. The other end of the plate body 15 is provided with a fourth through hole 151 which is provided with a screw 1510 and is connected to a bicycle 3.

Please refer to FIG. 3 and FIG. 5, which are schematic diagrams showing the first and second embodiments of the connecting mechanism of the present invention. As shown in Fig. 4, when the user rotates the screw cap 14 downward (or to one end of the first rod body 10 and the second rod body 11) to the tightest position, the spring 13 is then compressed to the tightest state. Therefore, the second rod body 11 is thus restricted in the accommodating space 1000 and cannot be rotated or tilted, so that the bicycle 3 is thus restricted from tilting; and in FIG. 5, the user starts to open the screw cap 14 (or When the other end of the second rod body 11 is rotated, the spring 13 can start to have elasticity and can perform reciprocating elastic pressure with a limited degree, and the other end of the second rod body 11 can be limitedly directed to the other end of the first rod body 10. Tilting, the bicycle 3 is also tilted in the direction in which the second body 11 is inclined.

Please refer to FIG. 6 again, which is a schematic diagram of a third embodiment of the connecting mechanism of the present invention. As shown in the figure, the third embodiment of the present invention is such that the length of the first fixing base 101 and the second fixing base 120 (both in the shape of a convex column) is adjusted, so that when the user tightens the screw cap 14, When the bottom is not yet screwed to the bottom, the first fixing base 101 and the second fixing base 120 have already touched each other, and the fixed bicycle 3 is also not inclined.

By means of the connecting mechanism disclosed in the present invention, we can rotate the cap to adjust the length of the spring, so that when the child learns the bicycle, the angle of the bicycle 3 to the bicycle auxiliary wheel 2 is completely fixed in the initial manner by locking the screw cap 4 To prevent the child from falling, and after the child learns to ride the bicycle for a period of time, the suspension cover 14 can be gradually loosened, so that the bicycle 3 is tilted to a limited extent but still does not cause the child to fall. In this way, by gradually increasing the degree of tilting of the bicycle to the left and right, the learning rider gradually adapts to the left and right balance to achieve the effect of learning to ride the bicycle.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
