[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 A widely used automotive crossbar includes a crossbar 1, with side covers 2 fixedly connected to both ends of the crossbar 1. A detachable tightening device is provided at the bottom of both ends of the crossbar 1. The tightening device includes a support 3 located below both ends of the crossbar 1. A slot is provided at the bottom end of the support 3. A locking block 6 is fixedly connected to the left and right side walls of the slot, and a stop block 7 is slidably connected to it. A locking component is provided at one end of the stop block 7.

[0020] With the installation of support 3 and side cover 2, in actual use, a crossbar 1 of appropriate length is selected according to different vehicles. Then, support 3 is fixedly connected to the bottom of both ends of crossbar 1, and side cover 2 is fixed to the left and right sides of crossbar 1. Support 3 is then installed on the two pre-reserved vertical bars on the top of the car. Finally, the locking components are adjusted to lock support 3 on the top of the car. The installation process is convenient and quick. During production, only crossbar 1 of the corresponding car model length needs to be produced. Side cover 2 and support 3 can be adapted to crossbar 1 to suit different car models, saving production costs.

[0021] Furthermore, referring to Figure 1-5 As shown, it is worth noting that the locking assembly includes a screw 10 rotatably disposed between the inner walls of the support 3 and a gear 12 meshing with the screw 10. A moving block 14 is fixedly connected to one side of the stop block 7 located inside the support 3. A rotating rod 13 is fixedly passed through the middle part of the gear 12. A bearing 11 is rotatably connected to one end of the rotating rod 13. The bearing 11 is fixedly connected to the inner wall of the support 3. The other end of the rotating rod 13 is threaded and is slidably connected to the moving block 14 through the thread. An operating hole 8 is opened on the outer wall of the support 3. The operating hole 8 is located at one end of the screw 10.

[0022] By setting the locking component, during use, the screw 10 is rotated by turning a handle that matches one end of the screw 10, causing the screw 10 to rotate and driving the gear 12 and the rotating rod 13 on the gear 12 to rotate. The thread at one end of the rotating rod 13 is slidably connected to the threaded hole on the moving block 14. The direction of rotation of the screw 10 can be controlled to control the direction of movement of the moving block 14 and the stop block 7 on the moving block 14, so that the stop block 7 and the locking block 6 clamp the longitudinal rod of the car to fix the support 3 and the crossbar 1 on the support 3, thereby achieving the purpose of fixing the crossbar 1.

[0023] Furthermore, referring to Figure 1-5 As shown, it is worth noting that a screw 9 is threaded onto the outer wall of the support 3, and one end of the screw 9 is inserted into the support 3 and fixedly connected to the rotating rod 13.

[0024] By using screw 9, in actual use, after the fixing assembly fixes the support 3 to the longitudinal rod of the car, screw 9 is fixedly connected to the rotating rod 13 to prevent the rotating rod 13 from rotating during the car's operation, which would cause the support 3 to detach from the longitudinal rod of the car, thus stabilizing the rotating rod 13.

[0025] Furthermore, referring to Figure 1-5 As shown, it is worth noting that the interior of the crossbar 1 is a cavity, and the bottom of both ends of the crossbar 1 are respectively provided with circular mounting holes 4 and 5. The support 3 is provided with holes that are compatible with the circular mounting holes 4 and 5.

[0026] With the circular mounting holes 4 and 5 provided, in actual use, bolts are passed through the circular mounting holes 4 and 5 respectively, and then the bolts are inserted into the holes on the support 3. Finally, nuts are used to fix the support 3 and the crossbar 1 together.
