Detailed Implementation

[0050] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0051] Embodiment 1, reference Figures 5-12 .

[0052] When the second crossbar support unit 004 is selected as the placing mechanism, first, during installation, the longitudinal rod front base 15 and the front base cushion 14 are installed on the roof, then the longitudinal rod rear base 12 and the rear base cushion 13 on the other side are installed on the roof according to the length of the profile rail 1, then the profile rail 1 is installed on the upper surface of the longitudinal rod front base 15 and the longitudinal rod rear base 12, then the rail long plastic piece 2 on one side is installed on the profile rail 1, then the slide knob 51 is rotated in sequence, so that the latch 55 can move upwards, and then the slide block plastic piece 53 is moved into the sliding groove of the profile rail 1.

[0053] Then the rear plug 6 is installed on the slide knob installation mechanism 5 provided with the limiting hole 522, and the front plug 7 is installed on the slide knob installation mechanism 5 provided with the mounting hole 521, and the slide knob installation mechanism 5 on the other side of the luggage support is mirror image arranged.

[0054] When the first second crossbar profile 321 is not rotated to open, the first second crossbar profile 321 on both sides is horizontally installed on the profile rail 1 on both sides, and when it is needed to rotate the first second crossbar profile 321 to open to become a vertical state for installing and fixing articles, the lock tongue button 63 on the rear plug 6 on one side is rotated, so that the lock tongue 66 is rotated out of the limiting hole 522, so that the rear plug 6 can be separated from the slide knob installation mechanism 5 that originally fixes it, and at this time, the rotation of the front plug 7 can be matched to rotate the rear plug 6 to the upper side of the slide knob installation mechanism 5 provided with the limiting hole 522 of the profile rail 1 on the other side, and then the lock tongue 66 is rotated by rotating the lock tongue knob 63, and then rotated into the limiting hole 522, so that the first second crossbar profile 321 can be fixed after changing from a horizontal state to a vertical state, and the first second crossbar profile 321 on the other side is also horizontally arranged in the same way and fixedly installed on the slide knob installation mechanism 5, so that the first second crossbar profile 321 on both sides changes to a vertical state and also maintains a parallel state.

[0055] When it is needed to adjust the distance between the first second crossbar profiles 321 on both sides, the latch 55 can be rotated by rotating the slide knob 51, so that the slide block plastic piece 53 can slide in the sliding groove on both sides, so that the distance between the first second crossbar profiles 321 on both sides can be adjusted, and the latch 55 can be rotated back to be clamped on the profile rail 1.

[0056] Embodiment 2, reference Figures 13-20 .

[0057] When the first crossbar support unit 003 is selected, first, when installing the luggage platform support of the car roof, first install the longitudinal rod front base 15 and the front base cushion 14 to the roof, then install the longitudinal rod rear base 12 and the rear base cushion 13 on the other side to the roof according to the length of the profile rail 1, then install the profile rail 1 to the longitudinal rod front base 15 and the longitudinal rod rear base 12 at the upper surface, then install the rail long plastic piece 2 on one side to the profile rail 1, and at this time, the profile rail 1 on both sides is provided with the installed first crossbar support unit 003.

[0058] The first crossbar support unit 003 installation process is that first, the T-shaped block is inserted into each second crossbar profile 32 T-shaped block slot, then the crossbar rubber strip 4 is clamped to the opening above each T-shaped block slot, then the installed crossbar profile installation mechanism 8 is inserted at the cavity at both sides of the second crossbar profile 32 end, so that the plug block on one side of the crossbar profile installation seat 88 can be inserted into the cavity of the second crossbar profile 32, and then the crossbar profile installation seat 88 is installed and fixed at both sides of the second crossbar profile 32 end by rotating and fixing the bottom part.

[0059] Then the sliding block seat 81 is installed into the sliding groove of the profile rail 1, and all the first crossbar support unit 003 is installed and can be used.

[0060] When the distance between the first crossbar support unit 003 needs to be adjusted, the limiting clamping plate 86 on both sides is rotated, so that the limiting clamping plate 86 can be rotated on the crossbar profile installation seat 88, and as the angle of the limiting clamping plate 86 changes, the rotating rod 88 will drive the latch 83 to be lifted, so that the latch 83 is lifted from the originally inserted limiting hole of the profile rail 1, so that the latch 83 is separated from the limiting hole, so that the sliding block seat 81 is not limited by the latch 83, so that it can slide longitudinally on the profile rail 1, so that the distance of each first crossbar support unit 003 can be adjusted.

[0061] After the distance of the first crossbar support unit 003 is adjusted according to the size of the object, it is ensured that the latch 88 of the first crossbar support unit 003 is located above the nearest limiting hole, then the limiting clamping plate 88 is rotated in the opposite direction, and under the release of the elastic potential energy of the latch spring 84, the latch 88 is pulled downward under the driving of the latch spring 84, so that it can be reinserted into the limiting hole below, so that the position of the crossbar profile installation mechanism 8 is fixed.

[0062] And when the limiting clamping plate 88 is rotated and opened, the T-shaped block in the T-shaped block slot on both sides can also be pulled out, so that it can be replaced.

[0063] In the present application, by setting the cross rod mounting frame unit 002, the installation and placement mechanism can be realized, and different placement mechanisms can be suitable for different use scenarios. The second cross rod support unit 004 and the first cross rod support unit 003 can slide on the profile rail 1, so that the spacing between the two sides can be adjusted. In this way, different sizes of articles can be installed. According to the weight of the article, the first cross rod support unit 003 or the second cross rod support unit 004 is selected. Such a roof luggage placement mechanism can place more articles and is more practical.

[0064] The second cross rod support unit 004 is simple in structure and can be accommodated on the two side cross rod mounting frame units 002. Although the first cross rod support unit 003 is in a large number, it has good firmness and can install heavier articles.

[0065] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes within the technical scope disclosed in the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
