[0023] Please see Figures 1-6 As shown, this utility model provides a technical solution:

[0024] A sliding rotating luggage rack is disclosed in this utility model to address the technical problems mentioned in the background art. It includes a crossbar 1, a rotating base 2, a locking base 3, and a rotating support rod 4. Two crossbars 1 are horizontally and parallelly mounted on a vertical rod on the roof via the rotating bases 2 and locking bases 3 on both sides. The rotating base 2 is equipped with a sliding rotation mechanism, allowing the crossbars 1 to slide and rotate to one side of the vehicle body. The locking base 3 is equipped with a locking mechanism to lock and fix the crossbars 1. The rotating support rod 4 connects the two crossbars 1, maintaining their parallel relationship. The rotating support rod 4 is equipped with an angle adjustment device to adjust the required angle.

[0025] The upper and lower sides of the crossbar 1 are respectively provided with an upper crossbar groove 102 and a lower crossbar groove 101. The lower crossbar groove 101 and the upper crossbar groove 102 are T-shaped or C-shaped grooves, which can be used as slide rails and for fixing. The front and rear sides of the crossbar 1 adopt an arc-shaped structure, which effectively reduces wind resistance.

[0026] The rotating base 2 consists of a rotating base 201 and a rotating base clamp 202 forming a C-shaped clamping mechanism. The rotating base clamp 202 is fitted inside the rotating base 201 and connected by bolts. The two rotating bases 2 are clamped to the roof vertical bar on one side. The rotating base 201 has a rotating base connecting ear 204 on the outside. Its upper plane is horizontal, which allows the crossbar 1 to remain horizontal when sliding on the roof, preventing the slot fixing block 303 from hitting the roof. At the same time, it can slide smoothly into the slot of the locking seat 301. The outer side of the rotating base connecting ear 204 has a certain angle. After contacting the slot fixing block 303, it restricts the rotation angle of the crossbar 1. The rotating slider 203 is hinged to the rotating base connecting ear 204 through the rotating slider lug 205, so that the crossbar 1 rotates around the hinge. The rotating slider 203 is equipped with a locking pin 6, which can cooperate with the opening on the crossbar 1 to lock.

[0027] The locking base 3 consists of a locking seat 301 and a locking seat clamp 302 forming a C-shaped clamping mechanism. The locking seat clamp 302 is fitted inside the locking seat 301 and connected by bolts. The two locking bases 3 are clamped to the roof vertical bars on the opposite side of the rotating base 2 and are aligned with the two rotating bases 2 respectively. The locking seat 301 is provided with a slot locking mechanism. The inner sliding groove can fit and lock the slot fixing block 303 to realize the sliding limit and fixation of the crossbar 1. The outer slot is provided with a locking switch 304. The locking switch 304 can unlock the locking tongue 305 provided on the slot fixing block 303. After the fixed crossbar 1 is unlocked, it can slide. The slot fixing block 303 is provided with a return spring 306. The return spring 306 pre-tightens the locking tongue 305 to maintain the locked state and prevent the crossbar 1 from sliding off due to accidental unlocking.

[0028] A slot fixing block 303 is fixedly installed on one side of the lower groove 101 of the crossbar. The locking mechanism of the slot fixing block 303 can slide into the slot provided in the locking seat 301 to limit and lock the crossbar 1. A rotating slider 203 is slidably installed on the other side of the lower groove 101 of the crossbar. After the rotating slider 203 is hinged to the rotating base 2, the crossbar 1 slides and rotates with the hinge point of the rotating base 2 as the base point. A bearing rod slider 5 is slidably installed in the upper groove 102 of the crossbar for connecting and fixing the rotating bearing rod 4.

[0029] The sliding part of the bearing rod slider 5 is embedded in the upper groove 102 of the crossbar. It can be moved to the required position and quickly locked by the quick-fixing screw 7 installed on the bearing rod slider 5. The upper part of the bearing rod slider 5 is provided with a slider lug 501. The upper end of the slider lug 501 is provided with 2 to 4 arc-shaped pin locking holes 502 at different angles, which can fix the rotating bearing rod 4 at different angles. The slider lug 501 is connected to the rotating bearing rod 4 through a hinge shaft, so that the rotating bearing rod 4 and the crossbar 1 are rotatably and slidably connected.

[0030] The rotating support rod 4 consists of a support part 403, a main connecting rod 401, and a secondary connecting rod 402. The support parts 403 on both sides are provided with positioning pins 405 on the side connected to the support rod slider 5. Under the action of the spring, the positioning pins 405 can engage with the pin lock 502, which can fix the rotating support rod 4 at different angles. When the torque applied to the rotating support rod 4 is greater than the set value, the positioning pins 405 compress the spring and unlock under the action of the arc-shaped pin lock 502, allowing rotation. A T-shaped rotating buckle 8 is installed on the other side of the support part 403, which can engage with the inside of the groove 102 on the crossbar and lock it after rotation, locking the rotating support rod 4 parallel to the crossbar 1 and fixing it together with the quick-fixing screw 7 of the support rod slider 5. The support part 403 is also provided with an installation waist-shaped hole 404. The support part 403 is used to install and place the supported items, and the installation waist-shaped hole 404 is used to connect and fix the supported items.

[0031] In this embodiment of the sliding rotating luggage rack, the first step is to unlock the fixing pin 6 on the rotating base 2, then press the locking switch 304 to unlock the locking tongue 305, slide the crossbar 1 out from one side of the rotating base 2 and rotate it down. When the slot fixing block 303 and the rotating slider 203 contact the limit, the maximum extraction distance is reached, and the crossbar 1 reaches its maximum rotation angle, then it is stably placed on one side of the vehicle. At this point, unlock the quick-fixing screw 7 and the rotating buckle 8, move the rotating support rod 4 down along the upper groove 102 of the crossbar to a suitable height, and then fix the support rod slider 5. Then rotate the rotating support rod 4 parallel to the ground for easy installation and removal of items. Finally, reset the luggage rack in reverse order to easily and conveniently complete the operation. When items are too tall, the height can also be reduced by moving and rotating the rotating support rod 4.
