As shown in FIGS. 3 to 7 , and in conjunction with FIGS. 1 and 2 , the quick positioning fastener 100 according to the embodiment of the present invention is hereinafter arranged in the fastener installation space S for installation on the roof rack action to explain. It should be noted that, for the sake of clarity, the following description will be based on the directions shown in the drawings, but these directions only represent relative concepts rather than absolute directions. The swing direction can be changed arbitrarily, for example, the up and down arrangement between the elements can be reversed, and the left and right arrangement can also be changed.

As shown in Fig. 3, in this embodiment, the lower mounting hole H2 of the luggage rack holder R consists of a mounting hole with a smaller diameter (the hole on the right in the figure) and a mounting hole with a larger diameter. The inlet hole portion (the hole on the left side in the figure) is radially connected and formed, and the upper mounting hole H1 corresponds to the mounting hole portion of the lower mounting hole H2 up and down. Corresponding to the structure of the luggage rack holder R, in the quick positioning fastener 100 of the present embodiment, the outer diameter of the outer sleeve member 1 is larger than the diameter of the installation hole of the lower installation hole H2, and The overall outer diameter of the outer sleeve member 1 and the inner sleeve member 2 is not larger than the diameter of the insertion hole of the lower installation hole H2.

The diameter of hole H1.

First, the manner in which the quick positioning fastener 100 is arranged in the fastener installation space S will be described. As shown in FIG. 3 , in this embodiment, the quick positioning fastener 100 passes through the lower mounting hole H2 from bottom to top with the inner sleeve member 2 up and the outer sleeve member 1 down. It is placed in the hole, and the whole is placed in the fastener setting space S. At this time, the total length of the quick positioning fastener 100 is configured to be smaller than the height of the fastener installation space S by the axial sliding of the inner sleeve member 2 in the outer sleeve shaft hole 10 . Moreover, in order to facilitate pushing the quick positioning fastener 100 into the fastener setting space S, it is preferable to connect an auxiliary tool T to the lower side of the outer casing member 1 of the quick positioning fastener 100 .

Next, as shown in FIG. 4 , by moving the auxiliary tool T, the quick positioning fastener 100 moves from left to right in the fastener setting space S along with the auxiliary tool T, so that the inner sleeve member 2, the upper section 21 of the inner sleeve corresponds to the upper installation hole H1, and the outer sleeve member 1 corresponds to the installation hole of the lower installation hole H2. In this state, since the outer diameter of the outer sleeve member 1 is larger than the diameter of the installation hole of the lower installation hole H2, the quick positioning fastener 100 cannot be pushed down through the installation hole of the lower installation hole H2. Thereby, the quick positioning fastener 100 is indwelled in the fastener setting space S. As shown in FIG.

Next, as shown in FIG. 5, the inner sleeve member 2 is pushed upward by the auxiliary tool T, and the diameter of the inner sleeve lower section 22 of the inner sleeve member 2 is due to the relationship between the outer protruding teeth 24 and the The interaction of the inner protruding teeth 11 contract, so that the inner sleeve member 2 is released from the positioning of the outer sleeve member 1 and axially slides upward relative to the outer sleeve member 1 in the outer sleeve shaft hole 10 . Thereby, the entire length of the quick positioning fastener 100 will be extended to a height corresponding to the fastener installation space S, so that the upper section 21 of the inner sleeve of the inner sleeve member 2 is correspondingly sleeved in the upper mounting hole In H1, the clamping outer flange 23 of the inner sleeve member 2 is clamped against the lower side of the upper mounting piece R1, and the lower end of the outer sleeve member 1 is clamped against the upper side of the lower mounting piece R2. At this time, the diameter D2 of the lower section 22 of the inner sleeve is elastically restored, so that the outer protruding teeth 24 of the inner sleeve member 2 and the inner protruding teeth 11 of the outer sleeve member 1 are correspondingly engaged again ( As shown in FIG. 2 ), the quick positioning fastener 100 is positioned in such an extended state and fixed in the fastener setting space S.

Next, as shown in FIG. 6 , after the auxiliary tool T is removed from the quick positioning fastener 100 , the inner sleeve shaft hole 20 and the outer sleeve shaft hole 10 of the quick positioning fastener 100 are connected to the luggage. The upper mounting hole H1 and the lower mounting hole H2 of the rack holder R are connected in series in the order of the upper mounting hole H1, the inner quill hole 20, the outer quill hole 10, and the lower mounting hole H2 , and form the roof rack installation lock hole that can directly pass through a screw B of the roof rack itself.

Next, the installation of the roof rack will be described. As shown in Fig. 7, in the installation of the roof rack, as long as the screw B of the roof rack (not shown) passes through the mounting lock hole of the roof rack (not shown) from one side, and On the other side of the installation lock hole, the screw B and a nut N are correspondingly screwed, so that the roof rack can be installed on the vehicle (the roof rack holder R), without the need for prior art as in the prior art. Precise alignment between the roof rack and the keyhole of the vehicle makes the installation more efficient.

With the above structure, the quick positioning fastener 100 can be quickly and conveniently installed in the fastener setting space S of the luggage rack holder R of the vehicle to form a luggage rack installation lock hole, so that the roof rack can be directly locked on the roof rack. The luggage rack is attached to the luggage rack holder R by mounting the lock hole. In this way, in the installation of the roof rack and the vehicle, the time wasted in readjusting the alignment can be saved, and the installation efficiency can be improved. Furthermore, the quick positioning fastener 100 of the present invention is adjusted and positioned in the fastener setting space S by the direct axial sliding of the inner sleeve member 2 relative to the outer sleeve member 1, compared to using a threaded screw. Fixing methods such as screwing in and out or adding fixing parts are easier to operate, faster and more convenient, so that the installation efficiency of the roof rack and the vehicle is better.

The above descriptions and descriptions are only the descriptions of the preferred embodiments of the present invention. Those with ordinary knowledge in the art can make other modifications according to the scope of the patent application defined below and the above descriptions, but these modifications should still be It is within the scope of the right of the present invention for the inventive spirit of the present invention.
