Description

Technical Field

[0001] The invention relates to a bicycle fixing rack. Background Art

[0002] A bicycle fixing rack is generally connected to the rear of a car for fixing bicycles, such as a bicycle fixing rack previously applied for by the applicant, with patent application number CN202111184963.8, which includes a connecting rod, a flipping device, a support rod device, a vertical rod and a strap. The connecting rod includes an upper connecting rod and a lower connecting rod. The upper and lower connecting rods are connected by a flipping device, so that the upper connecting rod can be flipped and folded by the flipping device. The upper connecting rod is provided with a support rod device, and the support rod device includes two support rods arranged perpendicular to the upper connecting rod, and a wheel seat is provided at each end of the two support rods. The upper connecting rod between the two support rods is also provided with a vertical rod, and a strap device is provided on the vertical rod. The above-mentioned flipping device includes a flip seat provided at one end of the upper connecting rod and a handle provided at the other end of the upper connecting rod. A positioning bayonet is provided on the flip seat, and a positioning pin is provided in the positioning bayonet. The positioning pin and the handle are connected by a pull rod provided in the upper connecting rod. A spring is provided at the end of the pull rod close to the handle, and the spring causes the pull rod to push the positioning pin against the positioning bayonet of the flip seat. At present, there are several defects in this bicycle fixing frame: first, the locating pin in the flipping device is only pressed against the locating bayonet of the flipping seat by the spring force of one end of the pull rod, and there is no locking device to lock the locating pin. When a car passes over a bumpy road, the vibration of the handle and the pull rod will compress the spring, causing the locating pin to disengage from the locating bayonet, and the bicycle will fall over; second, this bicycle fixing frame carries two bicycles and is fixed to one vertical pole, and the two bicycles need to be placed end to end on the support rod device so that the handlebars of the two bicycles will not be twisted together. However, in order to keep the two bicycles balanced on the same vertical pole by using a strap, the bicycles can only be tied to the bicycle top tube, and some bicycles do not have a top tube, so it is difficult to fix them; in addition, the strap seat of the strap device of this bicycle fixing frame is fixed to the vertical pole and cannot rotate. The strap can only be tied to the horizontal top tube of the bicycle. If a bicycle without a top tube is fixed, the strap will be tied to the down tube or the middle tube. Since the strap direction is non-rotatable, it is difficult to tie the bicycle to the vertical pole. Summary of the Invention

[0003] In view of the defects of the existing bicycle fixing racks, the technical problem to be solved by the present invention is to provide a bicycle fixing rack with more secure positioning pins; at the same time, the bicycle fixing rack needs to have a rotatable effect of double upright poles and a binding device.

[0005] The bicycle fixing frame can rotate the adjusting knob so that the screw head of the adjusting knob can firmly contact the clamping interface end of the V-shaped piece, so that the clamping interface can clamp the pull rod to prevent the pull rod from moving.

[0006] Preferably, the support rod device includes two parallel support rods, the middle parts of the two support rods are fixed on the upper connecting rod, and are respectively located on both sides of the vertical rod device, and wheel seats are respectively provided at both ends of the two support rods, and straps are provided on the wheel seats.

[0007] Preferably, the vertical pole device includes a fixed rod, two vertical poles and a binding device. The fixed rod has a U-shaped hollow rod in cross section and a square notch in the lower middle portion. The notch is clamped on the upper connecting rod and welded to the upper connecting rod. The two vertical poles are arranged in the fixed rod on both sides of the notch. A binding device is provided on the upper ends of the two vertical poles. The binding device includes a fixed seat, a connector, a rotating seat and a binding strap. The fixed seat is a frame-shaped body with an opening on one side, and the opening is locked by a locking bolt. A hollow bolt column is provided on the fixed seat on the side opposite to the opening. The connector is U-shaped, and the center of its closed end is movably fixed to the hollow bolt column of the fixed seat by a bolt, so that the connector can rotate. An axial hole is provided on one side of the rotating seat, and a pin is passed through the two ends of the axial hole to fix to both sides of the open end of the connector. A lock buckle is also provided on the rotating seat on this side, and a binding strap is fixed on the other side of the rotating seat. The above design achieves the technical effect of the rotatable binding device.

[0008] Compared with the prior art, the advantages of the present invention are: 1. The V-shaped piece is pressed against the adjusting knob of the locking device to firmly clamp the locating pin in the locating notch of the flip seat. Even if the car goes over a bumpy road, the pull rod will not pull the locating pin out of the locating notch of the flip seat due to vibration, thereby preventing the bicycle from falling. When the upper connecting rod needs to be flipped, the adjusting knob is first loosened so that the bolt end of the adjusting knob is rotated to the bottom of the V-shaped piece, and the handle can pull the pull rod to disengage the locating pin from the locating notch of the flip seat; 2. The upright rod device is respectively provided with an upright rod on both sides of the upper connecting rod through the fixing rod. When two bicycles are placed oppositely, the two upright rods are just on the middle tube under the bicycle seat. In this way, the middle tube of the bicycle can be tied and fixed to the upright rod by a strap, and the fixation is not affected even if the bicycle has no top tube; 3. The strap device can rotate 360 ​​degrees, so that the fixed part of the bicycle can be tightly fixed even if there is an angle difference between the fixed angle and the upright rod.
