All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0023] See also Figure 1-6 The embodiment of the present invention provides a technical solution: a multi-angle connecting member for a vehicle-mounted luggage rack support ladder, comprising a U-shaped frame 1, the inner cavity of the U-shaped frame 1 is rotatably sleeved with a connecting rod 5 through a locking bolt 3, and the top of the connecting rod 5 is rotatably sleeved with a rotating member 8 through a second latch 7, and a limiting slot 9 is symmetrically provided at the end of the rotating member 8, and a locking assembly 6 is provided between the inner cavity and the surface of the connecting rod 5, a first latch 4 is provided between the connecting rod 5 and the U-shaped frame 1, and a connecting end 2 is integrally extended from the bottom of the U-shaped frame 1, and a through hole is provided on the surface of the connecting end 2, and the connecting rod 5 and the U-shaped frame 1 are consistent with the inner cavity of the connecting rod 5 and the rotating member 8. The surface of the second latch 7 is provided with a rotating buckle, which can be connected to a rope, and the second latch 7 can be taken out by pulling the rope later, or the rope can be connected to the luggage rack. Secondly, the rotating member 8 is movably connected to the luggage rack through the connecting member.
[0024] See also Figure 5 The locking assembly 6 includes an insert rod 61 and a sleeve rod 62. The ends of the insert rod 61 and the sleeve rod 62 extend outside the surface of the connecting rod 5. The inner cavity of the sleeve rod 62 is movably sleeved with a spring 63, and the insert rod 61 and the sleeve rod 62 are both slidably sleeved in the inner cavity of the connecting rod 5. One end of the sleeve rod 62 is inserted into the inner cavity of the insert rod 61, and the spring 63 respectively abuts against the inner wall of the connecting rod 5 and one end of the insert rod 61. The surface of the insert rod 61 and the end of the sleeve rod 62 have the same diameter and are engaged with the limiting groove 9. The number of the limiting grooves 9 is symmetrical, one on each of the three sides and one in the middle. By changing the engagement of the three limiting grooves 9 with the locking assembly 6, it is convenient to store the support ladder and use the car left and right. In addition, pressing the insert rod 61 can drive the sleeve rod 62 to move, so that the surface of the insert rod 61 and the end of the sleeve rod 62 leave the limiting groove 9. After losing the limit, the connecting rod 5 can rotate in the inner cavity of the rotating member 8.
[0025] During installation, first insert the end of the supporting ladder into the inner cavity of the connecting end 2. Through holes are provided on the surfaces of the end of the supporting ladder and the connecting end 2, so the connection is completed by passing the positioning pin through the through hole through the connecting end 2 and the end of the supporting ladder.
