DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1-5 As shown, the utility model solves the problems that the existing roof bicycle racks are cumbersome to install and cause great damage to the roof of the car, and provides the following technical solutions: a roof bicycle rack quick connection seat, comprising a base plate 1 and a box body 3 arranged on the upper side of the base plate 1, and the two ends of the base plate 1 are provided with fixed feet 13, and the two ends of the box body 3 are hollowed out and installed with cam buckles 4, and the cam buckles 4 are rotatably connected with the corresponding fixed feet 13. When the cam buckle 4 rotates toward the base plate 1, the fixed feet 13 are lifted up until the cam buckle 4 is in a horizontal state, and a pair of bicycle rack connecting columns 2 are installed in the middle part of the upper side of the box body 3. By providing the fixed feet 13 and the corresponding cam buckles 4, the connecting seat can be quickly fixed to the roof by pressing the cam buckle 4, and the bicycle rack connecting column 2 has enough space to install the bicycle rack.

[0024] Specifically, Figure 6As shown, the cam buckle 4 includes a paddle 41 and connecting blocks 42 located on both sides of the lower part of the paddle 41. The bottom of the connecting block 42 is provided with a plane 43. One end of the connecting block 42 is rotatably connected to the upper end of the fixed foot 13. The end of the connecting block 42 connected to the fixed foot 13 is provided with an arc surface 44 extending to the plane 43. When the paddle 41 rotates toward the bottom plate, the plane 43 is in contact with the bottom plate 1, so that the fixed foot 13 remains in an upward state. When the paddle 41 is lifted, the arc surface 44 is in contact with the bottom plate 1, and the fixed foot 13 descends. The structure is simple and reliable, and the operation is convenient. The fixed foot 13 can be put into the mounting hole sideways, and then put straight. After the fixed foot 13 is lifted, the roof plate can be clamped. Among them, the fixed foot 13 is T-shaped, and the T-shaped fixed foot 13 is convenient for buckling the mounting hole or mounting groove on the roof, and is firmly installed.

[0025] Since the roof of a car is often curved, the overall shape of the bottom plate 1 can also be curved. When the fixing foot 13 is lifted, the bottom plate 1 can be deformed to fit the roof, covering the mounting hole and sealing it to prevent water leakage. A plurality of reinforcing rib frames 15 are arranged on the upper side of the bottom plate 1 to improve the overall strength of the bottom plate 1 and prevent it from breaking.

[0026] In this embodiment, if Figure 4-5 As shown, an anti-theft lock assembly is installed inside the box body 3 near one of the cam buckles 4, and the anti-theft lock assembly includes a laterally placed lock shaft 12, the axial first end of the lock shaft 12 is the driving end, and an arc groove 11 is arranged around the center on the axial second end face of the lock shaft 12, and a transverse locking rod 8 is installed on the side of the axial second end of the lock shaft 12, and the transverse locking rod 8 can rotate around its center, and the first end of the transverse locking rod 8 is abutted against the axial second end face of the lock shaft 12, and an embedding groove 7 matching the second end of the transverse locking rod 8 is arranged on the side of the cam buckle 4. The anti-theft lock assembly can prevent the bicycle frame and the connecting seat from being stolen. The transverse locking rod 8 can be swung by rotating the lock shaft 12, thereby realizing the locking and unlocking of the corresponding cam buckle 4, which is very convenient. Specifically, as the lock shaft 12 rotates, when the first end of the transverse locking rod 8 enters the arc groove 11, the second end of the transverse locking rod 8 disengages from the embedding groove 7, and when the first end of the transverse locking rod 8 leaves the arc groove 11, the second end of the transverse locking rod 8 embeds into the embedding groove 7, so that the cam buckle 4 cannot rotate. At this time, the cam buckle 4 is in a horizontal state, and the connecting seat is in an installed and fixed state and cannot be disassembled. In this way, the connecting seat and the bicycle frame cannot be disassembled and taken away.

[0027] In this embodiment, if Figure 5As shown, a positioning column 9 connected to the base plate 1 is vertically penetrated in the middle of the transverse locking rod 8, and a coil spring 10 is sleeved on the positioning column 9. One end of the coil spring 10 is connected to the transverse locking rod 8, and the other end is connected to the base plate 1. The position of the transverse locking rod 8 can be positioned by setting the positioning column 9, and at the same time, the coil spring 10 allows the transverse locking rod 8 to remain in a locked state or an unlocked state and will not rotate by itself.

[0028] In this embodiment, if Figure 4-5 As shown, the axial first end of the lock shaft 12 is connected to the lock head 5 rotatably mounted on the side wall of the box body 3, and a lock groove 6 is provided on the end face of the lock head 5. The lock groove 6 matches a special key or unlocking tool. After being inserted into the lock groove 6, the lock head 5 can be rotated. The lock shaft 12 and the lock head 5 can be connected by axial plug-in.

[0029] In this embodiment, if Figure 4-5 As shown, a snap-on spring piece 14 is installed on one radial side of the lock head 5, and the end of the snap-on spring piece 14 is buckled with the box body 3, which is convenient for the installation of the lock head 5. When the lock head 5 is inserted into the side wall of the box body 3, pressing it inward can realize the buckling connection between the snap-on spring piece 14 and the box body 3, and also make the lock head 5 generate a certain resistance when rotating, thereby improving the rotation texture.

[0030] At the same time, a circle of limiting grooves 16 is set in the middle of the lock shaft 12, and a limiting boss embedded in the limiting groove 16 is set on the box body 3. The limiting groove 16 and the limiting boss can cooperate to limit the axial position of the lock shaft 12 so that it will not deflect when it rotates.
