A limiting seat movable opening 313 is provided on the upper surface of the telescopic support rod 31 on one side of the axle pin movable opening 312, and a limiting support 7 is provided at the limiting seat movable opening 313. The limiting seat movable opening 313 facilitates the movement of the limiting support 7 and limits its range of movement.

[0052] Moreover, a movable groove 72 is provided on the upper surface of the base of the limiting support 7, and a second limiting protrusion 74 is movably provided at the movable groove 72. A spring 73 is symmetrically provided on the top of the second limiting protrusion 74. One end of the spring 73 is provided on the top of the second limiting protrusion 74, and the other end of the spring 73 away from the second limiting protrusion 74 is against the top wall of the movable groove 72. A mounting groove 71 is provided on one side of the movable groove 72 on the upper surface of the limiting support 7, and a rubber gasket 8 is provided at the mounting groove 71. The second limiting protrusion 74 can be inserted into the limiting opening 111. The spring 73 allows the second limiting protrusion 74 to be reset in cooperation with the spring 73 after it contracts.

[0053] At the same time, a sliding hole 52 is opened in the middle of the connecting seat 5, and a fixing component 6 is passed through the sliding hole 52. The threaded end of one side of the fixing component 6 is screwed on the clamping block axis pin 321. The connecting seat 5 is located on the side surface where the clamping component 4 is installed, and protrusions 53 are symmetrically provided on both sides. A bolt hole 51 is opened on the bottom end surface of one side of the base body of the connecting seat 5, and the telescopic support rod 31 is installed at the bolt hole 51 of the connecting seat 5. The protrusion 53 is convenient for limiting the swing angle of the clamping component 4.

[0054] In addition, the clamping assembly 4 includes a mounting bracket 41, one side surface of the mounting bracket 41 is mounted on the inner cavity side wall of the cross bar plug shell 22, and the mounting bracket 41 is rotatably connected to the other side frame body away from the cross bar plug shell 22 with a rotating connecting rod frame 43, and the rotating connecting rod frame 43 includes a nut pin 432, and the upper part of the nut pin 432 is rotatably provided with an upper connecting rod 433, and the lower part of the nut pin 432 is rotatably provided with a lower connecting rod 431, and a locking bracket 45 is rotatably provided on the upper connecting rod 433, and a hook pressure plate 42 is provided between the locking bracket 45 and the upper connecting rod 433, and the upper connecting rod 433 and the lower connecting rod 431 are used to allow the locking bracket 45 and the hook edge 42 to move relative to each other.

[0055] In addition, one end of the hook pressure plate 42 is rotatably set at the upper connecting rod 433, and the other side is installed at the column of the locking bracket 45. A first hook mounting seat 01 is inserted and installed between the hook pressure plate 42 and the locking bracket 45. A hook socket 421 is provided on the hook pressure plate 42, and a locking block limit opening 422 is provided on the upper surface of the hook pressure plate 42. The hook socket 421 facilitates the insertion of the hook.

[0056] Moreover, a hook is provided on the first hook mounting seat 01, and the hook can pass through the hook socket 421 and be inserted between the hook pressure plate 42 and the locking bracket 45. A locking protrusion 451 is provided on the upper surface of the locking bracket 45, and the locking protrusion 451 can be snapped into the locking block limit opening 422. The locking protrusion 451 is easy to snap into the locking block limit opening 422.

[0057] Moreover, a torsion spring 44 is provided at one end of the column of the locking bracket 45, and the bottom of the torsion spring 44 is connected to the nut pin 432, and the top of the torsion spring 44 is against the lower surface of the hook pressure plate 42. The mounting bracket 41 is symmetrically provided with first limiting protrusions 411 on both sides of the side surface facing the connecting seat 5. The first limiting protrusion 411 is provided with multiple grooves, and the protrusion 53 contacts the first limiting protrusion 411. Movable limiting holes 412 are provided on the top of the side walls on both sides of the mounting bracket 41 body, and the ends on both sides of the rod body of the upper connecting rod 433 are provided at the movable limiting holes 412. The movable limiting holes 421 can make the column at the top of the upper connecting rod 431 always movable in a vertical straight line.

[0058] In this embodiment, when the luggage rack is installed as a whole on the roof, the flush crossbar assembly 1 is first installed, the quick-release leather strip 12 is embedded in the groove at the top of the crossbar 11, and then the crossbar 11 is inserted into the installation cavity 221 of the crossbar plug shell 22 on both sides, and the limit unit 3 is inserted into both sides of the cavity of the crossbar 11.

[0059] After the limiting unit 3 is inserted into the cavities on both sides of the cross bar 11, after the limiting unit 3 is inserted, the second limiting protrusion 74 at the bottom of the limiting support 7 is squeezed by the bottom wall of the inner cavity of the cross bar 11, and then the second limiting protrusion 74 can be squeezed into the movable groove 72, and the spring 73 can also shrink, and then the telescopic support rod 31 slides in the cross bar 11. Once the second limiting protrusion 74 slides to the limiting opening 111 inside the cross bar 11, the second limiting protrusion 74 is no longer restricted by the bottom wall of the inner cavity of the cross bar 11. At this time, the spring 73 releases its elastic potential energy, and pushes the second limiting protrusion 74 out of the movable groove 72, so that it is stuck in the limiting opening 111, thereby fixing the limiting unit 3.

[0060] Furthermore, a rubber gasket 8 can be installed in the mounting groove 71, so that after the limiting unit 3 is inserted into the inner cavity of the cross bar 11, the rubber gasket 8 is wrapped around the outside of the screw portion of the fixing component 6, thereby providing damping during sliding and preventing the limiting unit 3 from sliding out easily.

[0061] When the limiting unit 3 is inserted into the inner cavity of the cross bar 11, the clamping block 322 cooperates with the clamping block axle pin 321, so that when the limiting unit 3 is inserted into the inner cavity of the cross bar 11, the clamping block 322 can clamp on the inner wall of the inner cavity of the cross bar 11 on both sides, and can be adjusted by the set fixing component 6, and the middle clamping and reset block 33 is selected from a material including but not limited to plastic, so that the support plate 311 limits the range of movement of the clamping and reset block 33, so that the flush longitudinal rod-free tripod assembly 2 is installed in the cross bars 11 on both sides without installing fixing components, and the disassembly process only requires simple plugging and unplugging, and its firmness is also good.

[0062] The limiting unit 3 is fixed to the inside of the crossbar plug housing 22 through the connecting seat 5, and the protrusion 53 on the connecting seat 5 is easy to cooperate with the groove on the limiting protrusion 411, so that the clamping assembly 4 can swing to a certain angle.

[0063] When installing the first hook mounting seat 01, the hook of the first hook mounting seat 01 is inserted into the clamping assembly 4, and the clamping assembly 4 is installed on the mounting block 224 through the mounting bracket 41 and is installed in conjunction with the fixing component, and the protrusion 53 is clamped in the limiting groove of the limiting protrusion 411, so that the rotation angle of the mounting bracket 41 is a constant value, so that the clamping assembly 4 drives the hook of the first hook mounting seat 01 to rotate a certain angle, so that the position of the cross bar 11 on both sides of the longitudinal bar-free tripod assembly 2 is movable, thereby increasing the overall versatility of the luggage rack and being suitable for more cars with different roofs.

[0064] When installing the hook of the first hook mounting seat 01, the hook is inserted from the hook socket 421 so that the installation hook can be located between the locking bracket 45 and the hook socket 421, and when the hook passes through the hook socket 421, the rotating locking bracket 45 will be pressed down first, so that it can press the locking protrusion 451 down. However, once the hook passes through and the locking protrusion 451 is located at the opening on the hook, the locking protrusion 451 cooperates with the action of the torsion spring 44 at this time, and the upper connecting rod 433 and the lower connecting rod 431 cooperate with the hook pressure plate 42 to rotate, so that the locking protrusion 451 can be tilted up, and the hook pressure plate 42 is pressed down, thereby jamming the inserted hook.

[0065] The fixing component fixes the rotating connecting rod frame 43, and the rotating connecting rod frame 43 makes the angle between the hook pressure plate 42 and the hook pressure plate 42 smaller, so that the clamping is more secure. The hook socket 421 is larger, and the locking protrusion 451 is semicircular, so that when the hook is clamped on it, the hook can swing to a certain angle.

[0066] In the present invention, the flush and longitudinal-bar-free tripod assembly 2 for supporting the cross bar 11 is set to a plug-in type, and the clamping mechanism 32 of the limiting unit 3 is used to make the flush and longitudinal-bar-free tripod assembly 2 effectively clamped in the inner cavity of the cross bar 11, and the second limiting protrusion 74 of the limiting support 7 can be clamped at the limiting opening 11. In this way, without using fixing parts, the flush and longitudinal-bar-free tripod assembly 2 of the plug-in type can be installed more firmly, which can improve the disassembly and assembly speed while ensuring that the firmness of its installation will not be affected. In addition, the set clamping assembly 4 can also quickly clamp the first hook mounting seat 01, and different hook mounting seats 01 can be installed, so that the flush and longitudinal-bar-free tripod assembly 2 can be installed on the roof of different cars, and its versatility is also better.

[0067] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
