The bearing force can be transmitted to prevent the spare tire from falling.

In addition, it is more preferable that the coupling portion 13 is formed such that an end to which the wire 12 is coupled has an uneven shape to be caught inside the latch 15.

Of course, even if the end of the engaging portion 13 is not formed in the uneven shape, the engaging portion 13 can be held by the latch 15 at a high pressure, but the pressure is continuously applied to the vehicle In this case, there is a risk that the support force for fixing the engaging portion 13 is weakened and the spare tire falls momentarily.

Therefore, it is preferable to form the end of the coupling part 13 in an uneven shape so as to be firmly fixed to the inside of the latch 15, and furthermore, to the inside of the latch 15. It is more preferable that the grooves are formed so that the unevenness of the grooves can support a large force, so that the spare tire does not fall even if a large impact is applied.

More preferably, gears for rotating the shaft 22 are embedded in the housing 21, and a spiral release spring 23 is coupled to one side of the shaft 22.

The release spring 23 has a circular spiral structure starting from the portion coupled with the shaft 22, and does not depart from the outside of the housing 21 when the release springs 23 are all released.

A release cable 24 is connected to the other end of the release spring 23 to be coupled to the latch 15.

Therefore, when the release spring 23 is compressed or released, the release cable 24 connected thereto is compressed or released, and accordingly, the latch 15 may rotate, and thus, the coupling portion 13 may be rotated. You can adjust the engagement and disengagement of the spare tire as you move.

The release spring 23 is more preferably made of a spring spring, and thus a constant tension is always maintained in the release cable 24 to maintain a constant position of the latch 15, thereby coupling the spare tire. Or it is easier to ensure operability to release.

In addition, since the required length of the release cable 24 can be reduced compared to the amount of rotation of the shaft 22 through the compressibility of the release spring 23, the required manufacturing process can be made simpler.

A more detailed operation of such a spare tire carrier drop prevention device is shown in Figs. 5A to 9B.

That is, before the spare tire is mounted on the spare tire carrier drop prevention device of the present invention, as shown in FIG. 5A, the release spring 23 is completely wound to closely contact the shaft 22, and thus the release cable The tension of 24 reaches a maximum.

Accordingly, as shown in FIG. 5B, the outer circumference of the latch 15 is rotated upward by the tension of the release cable 24 to be released, and the wire 12 is completely released. The coupling part 13 is moved to the lowest position.

Therefore, the spare tire is fixed to the coupling part 13 and the support bracket 14 connected thereto.

Then, in order to mount the spare tire to the spare tire carrier drop prevention device of the present invention, as shown in Fig. 6A, the shaft 22 is rotated in the direction in which the release spring 23 is wound (counterclockwise). As a result, the release spring 23 is gradually released to reduce the tension transmitted to the release cable 24.

Accordingly, as shown in FIG. 6B, the latch 15, which has been rotated upwards and is tightened, is gradually locked downward and locked, and the wire 12 positioned at the center of the latch 15 is locked. ) Is gradually wound upward while winding to secure the coupling portion (13).

Figures 7a and 7b are shown after all of these mounting procedures are completed. That is, the release spring 23 is fully released so that the tension applied to the release cable 24 is kept to a minimum.

In addition, the latch 15 connected to the release cable 24 is completely rotated downward and locked, the wires 12 are all wound, and the coupling part 13 is the latch 15. It is completely combined with and fixed.

This state is maintained during normal vehicle operation, and the coupling part 13 which is engaged with the latch 15 even when the wire 12 is broken, as compared with the case where the spare tire is fixed only with a wire as in the related art. Since the spare tire can be fixed, the secondary safety accident due to the fall of the spare tire can be prevented.

Subsequently, when the spare tire is to be used, as shown in FIG. 8A, the release spring 23 is wound by rotating the shaft 22 so that the release cable 24 is wound (clockwise). In addition, the tension applied to the release cable 24 is gradually increased.

Thus, as shown in FIG. 8B, the latch 15 connected to the release cable 24 starts to release as it rotates upwards, and the wire 12 positioned at the center of the latch 15 is released. And the coupling part 13 is moved downward.

Thereafter, as shown in FIGS. 9A and 9B, when the release spring 23 is completely wound by the rotation of the shaft 22, the tension applied to the release cable 24 reaches a maximum, and Since the latch 15 connected to the release cable 24 is lifted upward as far as possible to release it, the wire 12 and the coupling part 13 are completely released.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
