(5) In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms center, horizontal, upper, lower, left, right, vertical, horizontal, top, bottom, inside and outside are based on the orientation or position relationship shown in the drawings, which is only intended to facilitate the description of the invention and to simplify the description, rather than to indicate or imply that the referred device or element must have a specific orientation or be constructed and operated in a specific orientation, and cannot be construed as a limitation to the present invention. In addition, the terms first and second are used only for the purpose of description and cannot be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined by first and second may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, a plurality of means two or more. In addition, the term include/comprise and any variation thereof is intended to cover exclusive inclusion.

(6) The present invention is further described in detail with reference to the drawings.

(7) In a specific embodiment of the present invention, the rotatable vehicle mounted bicycle rack includes a L-shaped fixed rod 1 with one end fixed to the rear of the car. The upper part of the other end of the L-shaped fixed rod is provided with a rotating base, and the rotating base includes two vertically arranged rotating plates 2. One end of the support beam 3 is rotatably connected between the middle parts of the rotating plates 2, and the other end of the support beam 3 is connected to the main body support 4. The main body support 4 includes two inverted T-shaped support plates. The cross rod 5 passes through two horizontal ends of the main body support 4 and is fixed to the main body support 4. The vertical rod 6 is rotatably connected to the upper part of the main body support 4. Each of the two ends of the cross rod 5 is connected to two wheel seats 7. The upper part of the vertical rod 6 is provided with two fixed hooks 8. The wheel seats 7 are respectively arranged on both sides of the cross rod 5. A group of wheel seats 7 arranged on the same side of the cross rod 5 include two wheel seats. The wheel seat 7 is provided with the first sleeve seat 9 and is sleeved on the cross rod 5. The first sleeve seat 9 is provided with a bolt for fastening. The fixed hooks 8 are respectively arranged on both sides of the vertical rod 6. The orientation of the fixed hooks 8 corresponds to the orientation of the group of wheel seats 7. The fixed hook 8 is provided with the second sleeve seat 10 and is sleeved on the vertical rod 6. The second sleeve seat 10 is provided with a bolt for fastening. The bottom end of the vertical rod 6 is provided with the fixed spring buckle 11. The hinge point between the vertical rod 6 and the main body support 4 is arranged above the fixed spring buckle 11. The main body support 4 is provided with three spring buckle holes 12 distributed in an inverted triangle configuration. The fixed spring buckle 11 is respectively engaged with the spring buckle holes 12 after being rotated. The upper part and one side of the rotating plates 2 are each provided with the clamping slot 13. Each of the sides of the support beam 3 facing the rotating plates 2 is provided with an elongated clamping slot. A stretching rod is inserted into the support beam 3, and each of the two sides of the stretching rod is provided with the clamping pin 14 matching with the elongated clamping slot. One end of the stretching rod is connected to the bottom of the support beam 3 through a spring, and the other end of the stretching rod is hinged to the middle of the handle 15. The end of the handle 15 opposite to a grip of the handle 15 is hinged to the main body support 4.

(8) The working principle of the present invention is as follows. The bicycle rack of the present invention includes the rotating base, the main body support 4, a spring pin mechanism in the support beam 3 and a pulling buckle mechanism. One end of the support beam 3 is connected to a circular hole in the middle of the rotating plate 2 by a screw. Two clamping slots are provided on the edge of the rotating plate 2. The clamping pin of the spring pin mechanism in the support beam 3 is automatically engaged into the clamping slot of the rotating plate 2 under an action of spring tension, so as to fix the support beam 3. When rotating the support beam 3, the handle 15 at the other end of the support beam 3 is pulled so that the clamping pin is accordingly pulled out from the clamping slot and disengaged from the rotating plate 2. When the support beam 3 rotates to another clamping slot, the clamping pin is automatically engaged into the clamping slot to fix the support beam 3 under the action of spring tension to realize a transformation between a horizontal state and a folding state.

(9) Two groups of wheel seats 7 configured to place the bicycle wheels are arranged on the cross rod 5 to move along the cross rod. The fixed hook on the vertical rod 6 configured to fix the bicycle on the wheel seat moves up and down along the vertical rod. In addition, the fixed spring buckle 11 is fixed on the vertical rod and is engaged with the fixed spring buckle hole 12. The fixed spring buckle is pressed so that the vertical rod rotates around the connection point and is fixed automatically.

(10) To sum up, pressing the fixed spring buckle that is located on the vertical rod to rotate the vertical rod to a position parallel to the cross rod fix the vertical rod. The handle can be pulled to rotate the support beam 3, and engage the support beam 3 into the clamping slot on the rotating base. Thus, placing the bicycle rack is in a vertical folded state.

(11) The present invention and the embodiments thereof have been described above. This description is not restrictive, the drawings only illustrate one of the embodiments of the present invention, and the actual structure is not limited to this. Generally, if those having ordinary skill in the art are inspired by the present invention and design structural implementations and embodiments similar to the technical solution without departing from the creative concept of the present invention, these structural implementations and embodiments shall fall within the scope of protection of the present invention.
