[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1-4 As shown, a car luggage rack mounting bracket comprises two supporting longitudinal bars 1, two supporting cross bars 2 are symmetrically distributed between the two supporting longitudinal bars 1, sliders 4 with cavities inside are fixed at both ends of the supporting cross bars 2, and slideways 3 adapted to the sliders 4 are transversely opened on the supporting longitudinal bars 1;

[0022] By setting the slider 4 and the slide 3, the slider 4 can be quickly displaced inside the slide 3 by pushing and pulling the support cross bar 2, so that the distance between the two support cross bars 2 can be quickly adjusted according to the size of the car luggage rack to be used, so that the two support cross bars 2 can carry car luggage racks of different sizes, thereby improving the scope of application.

[0023] Further, refer to Figure 3 and Figure 4 As shown, it is worth noting that an elastic plug-in for locking the slider 4 in the inner side of the slideway 3 is provided in the inner cavity of the slider 4, and a movable slit 10 is provided in the inner wall at both ends of the support crossbar 2, and an extrusion piece matching the elastic plug-in is provided in the movable slit 10, and a transmission component for causing two groups of extrusion pieces to operate synchronously is provided on the plate body of the support crossbar 2;

[0024] The elastic plug-in includes a positioning column 5 vertically arranged in the inner cavity of the slider 4 and a plurality of positioning holes 8 equidistantly opened on the top surface of the supporting longitudinal rod 1. The positioning hole 8 is connected to the inner side of the slideway 3. The top surface of the slider 4 is provided with a movable hole for the positioning column 5 to pass through and retract. One end of the positioning column 5 passes through the movable hole and corresponds to one of the positioning holes 8.

[0025] The extrusion member includes a connecting rod 11 which is laterally slidably arranged inside the movable seam 10 and an extrusion plate 12 which is tightly sleeved on the connecting rod 11. The connecting rod 11 and the extrusion plate 12 are vertically distributed. The other end of the positioning column 5 is in the shape of an inclined slope. One end of the extrusion plate 12 is in an arc shape and penetrates into the inner cavity of the slider 4 to abut against the slope surface of the positioning column 5.

[0026] By setting the elastic plug-in, extrusion piece and transmission component, after completing the position adjustment of the supporting cross bar 2, it is only necessary to use the transmission component to make the connecting rods 11 in the inner walls of the two ends of the supporting cross bar 2 slide in opposite directions synchronously, so that the two extrusion plates 12 respectively penetrate into the inner cavity of the corresponding slider 4 and abut against the inclined slope of the positioning column 5, so that the positioning column 5 slides up and penetrates into the corresponding positioning hole 8, thereby realizing the locking effect of the two ends of the supporting cross bar 2 on the two supporting longitudinal bars 1 synchronously, thereby replacing the use of the fixings in the prior art, and there is no need to manually install the fixings on the two supporting longitudinal bars 1 in turn after the position adjustment of the supporting cross bar 2, which effectively reduces the work intensity and improves the work efficiency.

[0027] Further, refer to Figure 4 As shown, it is worth noting that a slide plate 6 is tightly sleeved on the rod body of the positioning column 5, and the side of the slide plate 6 is slidably connected to the inner wall of the slider 4, and a compression spring 7 is sleeved on the rod body of the positioning column 5 located above the slide plate 6, one end of the compression spring 7 is fixed to the slide plate 6, and the other end of the compression spring 7 is fixed to the inner wall of the top end of the slider 4;

[0028] As shown above, when the positioning column 5 is squeezed and slides up by the extrusion plate 12, the positioning column 5 can carry the slide 6 to move up synchronously and compress the clamping spring 7 to deform. In this way, by utilizing the elastic force of the clamping spring 7, when the extrusion plate 12 slides in the opposite direction and no longer squeezes the positioning column 5, the slide 6 can act on the positioning column 5 under the elastic force of the clamping spring 7 to automatically move downward and reset, which is convenient for secondary use.

[0029] Further, refer to Figure 4 As shown, it is worth noting that the transmission component includes two movable seats 9 symmetrically slidably sleeved on the rod body of the supporting crossbar 2, and the two ends of the movable seam 10 are respectively fixedly connected to the inner walls of the two sides of the movable seat 9;

[0030] The transmission component also includes a bidirectional screw 14 disposed laterally on the side of the movable seat 9 and two nut seats 15 symmetrically threadedly connected to the rod of the bidirectional screw 14. The two nut seats 15 are respectively fixed to the two movable seats 9. Both ends of the bidirectional screw 14 are rotatably sleeved with a fixing plate 13 fixed perpendicularly to the outer wall of the supporting cross bar 2.

[0031] By twisting the bidirectional screw 14 , the two nut seats 15 and the movable seat 9 can slide synchronously in opposite directions, so that the connecting rods 11 on the inner walls of the two ends of the supporting cross bar 2 move in the same direction, thereby providing power for the extrusion plate 12 .

[0032] Further, refer to Figure 4 As shown, it is worth noting that an inclined reinforcing rib 16 is fixed to the bottom surface of the movable seat 9, an insert block 17 is fixed to the end of the reinforcing rib 16, and a plug hole matching the insert block 17 is opened on the supporting longitudinal rod 1;

[0033] When the movable seat 9 slides toward the supporting longitudinal rod 1, the insert block 17 on the reinforcing rib 16 can be synchronously aligned and inserted into the insertion hole, so that the supporting longitudinal rod 1, the supporting cross bar 2 and the reinforcing rib 16 form a triangle shape, which can effectively enhance the bearing and compressive resistance of the end of the supporting cross bar 2 and improve the connection strength between the end of the supporting cross bar 2 and the supporting longitudinal rod 1.
