The present disclosure relates to a two-way foldable spare tire rack for a vehicle.
Spare tire refers to the spare tire of the car, which is used to prevent the tire burst and air leakage while the car is driving, and avoid the inconvenience caused by the anchor halfway; For most large SUVs, RVs, etc., a tow bar is set at the rear of the chassis, and the owner can configure the spare tire rack according to the needs. The spare tire rack is fixedly connected to the tow bar, and the spare tire is mounted on the spare tire rack to solve the trouble of traveling.
The existing spare tire racks are basically rigid, so it is inconvenient to pack and deliver the rigid spare tire racks. At the same time, after the rigid spare tire racks are fixedly installed, it is very laborious to disassemble the spare tires on the spare tire racks, especially for female drivers.
In view of the shortcomings of the above problems, the present disclosure provides a two-way foldable spare tire rack for a vehicle.
In order to achieve the above purpose, the present disclosure provides a two-way foldable spare tire rack for a vehicle, which includes a fixed frame assembly for fixing a spare tire and a movable bar frame assembly arranged at one side of the fixed frame assembly, characterized in that: the fixed frame assembly comprises a positioning joint pipe, a support pipe arranged above the positioning joint pipe, a rotating member and a rotation limiting member, wherein the positioning joint pipe and the support pipe form a rotatable structure through the rotating member, and the rotation limiting member is used for limiting the rotation between the support pipe and the positioning joint pipe to keep them in a use state; a long bracket pipe is fixed above the support pipe, and a bracket plate is fixed at a free end of the long bracket pipe; the movable bar frame assembly comprises an adjusting plate, a movable square pipe and at least one locking member which are rotationally connected, wherein the adjusting plate is fixedly connected to one side of the positioning joint pipe, and the locking member is used for locking the adjusting plate and the movable square pipe in the use state.
The fixed frame assembly and the movable bar frame assembly of the vehicle spare tire rack can be folded, the movable bar frame assembly is convenient for packaging and delivery through folding, and the fixed frame assembly is convenient for the spare tire on the bracket plate to be transferred to contact with the ground surface and then disassembled, which is convenient and labor-saving.
As a further improvement of the solution, the rotating member and the rotation limiting member are bolts of a same size, and the positioning joint pipe and the support pipe are provided with an upper hole position and a lower hole position at the overlapping position that are perforative for two bolts to pass through.
In the technical solution, one bolt penetrates the lower hole to be used as a rotating shaft, so that a rotating structure is formed, and the other bolt penetrates the upper hole to achieve a limiting effect.
As a further improvement of the solution, the cross-sectional size of the support pipe is smaller than that of the positioning joint pipe, the cross-sectional size of the long bracket pipe is consistent with that of the positioning joint pipe, and an upper end of the positioning joint pipe is also provided with a reinforcing plate with a U-shaped cross section, and the upper hole position and the lower hole position simultaneously penetrate through the reinforcing plate.
In the above technical solution, the support pipe and the positioning joint pipe are in a rotating structure, and there is bound to be a difference in size. The difference in size makes the rotation of the support pipe offset to a certain extent. The support pipe is designed to be smaller than that of the positioning joint pipe, and the reinforcing plate is configured to eliminate the offset of the two rotation, so that the rotation is more stable.
As a further improvement of the solution, the overlapping position of the long support pipe and the reinforcing plate is processed with a rotation limiting hole position for one of the bolts to pass through.
In the above technical solution, the rotation limiting hole position is perpendicular to the upper hole position or the lower hole position, and the mode of one bolt directly penetrating the rotation limiting hole position and one bolt penetrating the upper hole position is more stable than the mode of two bolts penetrating the upper and lower holes respectively.
As a further improvement of the solution, the nut of one of the bolts can be welded on the side of the reinforcing frame.
In the above technical solution, in the folding process of the fixed frame assembly, the screw of the redundant bolt can be directly screwed on the welded nut to avoid losing, but the rotation of the fixed frame assembly needs to be locked, and the screw of the bolt only needs to be screwed into the rotation limiting hole, while the other end does not need the nut.
As a further improvement of the solution, there are two locking members, and when in use, the two locking members pass through the overlapping part of the adjusting plate and the movable square pipe.
In the above technical solution, the connecting structure is more stable through the action of the two locking members.
As a further improvement of the solution, the movable square pipe or/and the adjusting plate is provided with a locking hole, and the locking member can be inserted in the position of the locking hole to lock the adjusting plate and the movable square pipe in a folded state.
In the above technical solution, the locking member is inserted into the locking hole, so that the folded movable bar frame assembly is stable.
As a further improvement of the solution, the movable square pipe is provided with a plurality of adjusting holes at equal intervals in the length direction;
In the technical solution, the movable square pipe is connected with the drag bar of the automobile chassis, and the adjusting hole is used for adjusting the distance to ensure that the trunk can be opened normally.
Compared with the prior art, the present disclosure has the beneficial effects that the fixed frame assembly and the movable bar frame assembly of the vehicle spare tire frame can be folded, the movable bar frame assembly is convenient for packaging and delivery through folding, and the fixed frame assembly is convenient for the spare tire on the bracket plate to be transferred to contact with the ground surface and then disassembled, so that disassembly and assembly are convenient and labor-saving.
