The aim of the utility model can also be solved by the following technical measures:
further, the head of the bolt is provided with a knob.
Furthermore, the connecting end is provided with a sliding block, and the sliding block is provided with the mounting cavity, the opening and the through hole.
Furthermore, the surface of the sliding block is provided with an upper pulley, the bottom surface of the sliding block is provided with a lower pulley, the sliding block extends into the sliding channel, the upper pulley is tightly attached to the inner wall of the sliding channel, and the lower pulley is tightly attached to the inner wall of the sliding channel. When the crossbeam slides, the upper pulley and the lower pulley rotate along with the crossbeam, so that friction is reduced, the crossbeam slides more smoothly, and a user can conveniently adjust the position of the crossbeam.
The utility model has the following beneficial effects:
according to the utility model, a user firstly loosens the bolt to enable the bolt to leave the jack, at the moment, the user can freely pull the cross beam to slide to adjust the position of the cross beam, the ball is positioned between the cross beam and the longitudinal rod by the aid of the ball, the ball has elasticity under the action of the spring, the cross beam cannot generate positioning deviation in the sliding process of the cross beam, parts are deformed, the ball is inserted into the corresponding jack to be positioned, the positioning is more accurate, the user can conveniently adjust the position of the cross beam, after the position of the cross beam is adjusted, the user penetrates the bolt through the through hole, then the knob is twisted to enable the bolt to be locked in the jack, the locking of the cross beam and the longitudinal rod is realized, the product is ensured to have good bearing performance, the looseness of the cross beam is avoided, the position of the cross beam can be adjusted, the cross beam and the longitudinal rod can be locked, and the user requirements are met.
According to the utility model, when the cross beam slides, the upper pulley and the lower pulley rotate along with the cross beam, so that the friction force is reduced, the cross beam slides more smoothly, and the position of the cross beam is convenient to adjust by a user.

Detailed Description
The utility model is further described with reference to the following figures and examples:
in the embodiment, as shown in fig. 1 to 7, the roof rack comprises a longitudinal rod 1, a transverse rod 2 and a connecting device, wherein the side wall of the longitudinal rod 1 is provided with a sliding channel 3 along the length direction thereof, and the sliding channel 3 is provided with inserting holes 4 at intervals along the length direction thereof.
Connecting device is including connecting end 5, ball 6, spring 7 and bolt 8, the head of bolt 8 is provided with knob 81, 5 one ends of connecting end are overlapped respectively and are put at 2 both ends of crossbeam, and the 5 other ends of connecting end are provided with slider 9, slider 9 embeds there is installation cavity 91, and the corresponding installation cavity 91 position of slider 9 outer wall is opened there is export 92, and export 92 diameter is less than the ball 6 diameter, and slider 9 is located installation cavity 91 both sides and has opened through-hole 93 respectively, and slider 9's surface is provided with upper pulley 94 in addition, and slider 9's bottom surface is provided with down pulley 95.
