[0026] Embodiment 1

[0027] The present embodiment provides a roof rack with expandable space, referring to Figures 1-5 which is installed on the roof 1 and comprises: a pair of mutually parallel longitudinal rods 2 longitudinally bolted on both sides of the surface of the roof 1, and a pair of mutually parallel crossbars 3 clamped and fixed at both ends of the longitudinal rods 2; the longitudinal rods 2 and the crossbars 3 form a rectangular frame structure; the crossbar 3 is composed of an inner rod I 4 and an outer cylinder 5 that are mutually sleeved and matched, the inner rod I 4 is slidingly connected with the outer rod, and the inner rod I 4 extends out of the outer cylinder 5 at one end, and the end is provided with a connecting rod 6, the connecting rod 6 is fixedly connected with the ends of the two inner rods I 4, forming a "∥" shaped structure. Through the above, by holding the connecting rod 6 of the "∥" shaped structure, the "∥" shaped structure can be pulled outwards to form an expansion platform, and the trunk 10 of the roof 1 or other objects can be placed on the expansion platform, thereby the space of the roof 1 can be emptied out for other purposes.

[0028] ​In this embodiment, the bottom of the crossbar 3 is connected with the vertical rod 2 through the clamping mechanism 7, which includes a fixed jaw 701 and a movable jaw 702. The top of the fixed jaw 701 is fixedly connected to the bottom side of the crossbar 3, and the movable jaw 702 forms a clamping jaw structure with the fixed jaw 701 for clamping on the roof rack of the roof 1. A horizontal sliding groove 703 is arranged on the fixed jaw 701, and the upper part of the movable jaw 702 is in sliding fit with the sliding groove 703. Coaxial threaded holes are arranged at the bottom of the sliding groove 703 and the upper part of the movable jaw 702, and an adjusting screw 704 is installed in the threaded holes. By rotating the adjusting screw 704, the position of the upper part of the movable jaw 702 in the sliding groove 703 can be adjusted according to the size of the vertical rod 2, and then the size of the clamping jaw structure formed by the bottom of the movable jaw 702 and the fixed jaw 701 can be adjusted to adapt to vertical rods 2 of different sizes.

[0029] Further, a first hook plate 705 is arranged at the bottom of the fixed jaw 701, and a second hook plate 706 is arranged at the bottom of the movable jaw 702 for hooking the bottom of the vertical rod 2. In use, the crossbar 3 body can be prevented from falling off the vertical rod 2, and the reliability of the fixation is improved.

[0030] In this embodiment, the outer cylinder 5 is provided with an end cover 8 at one end away from the “Dang” shaped structure, the inner rod I 4 is of a solid structure, and a first locking hole is arranged at one end of the inner rod I 4 close to the end cover 8. Correspondingly, a second locking hole corresponding to the locking hole is arranged on the end cover 8. A locking screw 9 is screwed into the first locking hole and the second locking hole to achieve the locking state of the inner rod I 4, so as to avoid the free movement of the inner rod I 4 in the outer cylinder 5. When the space of the roof 1 needs to be expanded, the locking screw 9 is screwed outward to make the inner rod I 4 in the unlocked state, and then it can be pulled out outward.

[0031] Further, the top of the crossbar 3 is fixed with a luggage box 10 through a clamping jaw mechanism, and the bottom of the luggage box 10 is provided with a sliding sleeve 11 in sliding connection with the crossbar 3.

[0032] Further, the upper part of the crossbar 3 is in the shape of a circular arc, and correspondingly, the cross-sectional shape of the sliding sleeve 11 is in the shape of a hoop adapted to the shape of the crossbar 3. Through the above, when the connecting rod 6 of the “Dang” shaped structure is pulled out outward, the clamping of the clamping jaw mechanism on the crossbar 3 is released, the sliding sleeve 11 at the bottom of the luggage box 10 is in sliding connection with the crossbar 3, and the horizontal movement of the luggage box 10 outward above the “Dang” shaped structure can be controlled, so as to realize the emptying of the space of the roof 1 and facilitate other uses.

[0033] Further, the connecting rod 6 is provided with a limiting protrusion 12 above, in order to limit the outward displacement distance of the luggage box 10 on the cross rod 3, and prevent it from being pulled off and falling.

[0034] In the embodiment, in order to maintain the stability of the entire expansion platform, the connecting rod 6 of the "H" shaped structure can be supported by the inclined ladder 13 at the lower end.

[0035] In another use method, referring to Figure 7 , the outer barrel 5 of the luggage box 10 is provided, without moving the top box, only the "H" shaped structure is pulled out, the "H" shaped structure is provided with the inclined ladder 13 on one side, and several auxiliary rods can be additionally arranged on the "H" shaped structure for support, and the pull-wire inflatable tent 18 is directly placed on the "H" shaped structure, so that the operation process is further simplified, and the top box does not need to be moved frequently.

[0036] Embodiment 2

[0037] In the embodiment, in order to maintain the stability of the entire expansion platform, the connecting rod 6 of the "H" shaped structure can be supported by the inclined ladder 13 at the lower end.
