The utility model can also be implemented or applied through different specific embodiments, and each detail in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the utility model. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0019] It should be noted that the drawings provided in the following examples only illustrate the basic concept of the utility model in a schematic manner, and only the components related to the utility model are shown in the drawings, not the number, shape and size of the components in actual implementation. The shape, number and proportion of each component in actual implementation can be changed arbitrarily, and the component layout pattern can also be more complex.

[0020] All the directionality indications (such as up, down, left, right, front, back, transverse, longitudinal, and the like) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement condition and the like between the components in a certain specific posture, and if the specific posture is changed, the directionality indications will also be changed accordingly.

[0021] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0022] The present utility model provides a kind of A-shaped foldable tire inflation protection frame, including main frame and U-shaped folding frame 3.

[0023] Referring to Figure 1 As shown in the figure, the main frame includes two square frames 1 and a bottom supporting plate 2, preferably, the square frame 1 is of rectangular structure, so that the length and width dimensions of the hollowed-out middle part are adapted to the diameter and thickness of the tire, thereby forming a relatively narrow gap when passing through the tire, improving stability, and the two square frames 1 are arranged in a parallel overlapping manner, so that the hollowed-out middle parts of the two square frames 1 are connected, and a connecting structure such as a hinge, a hinge, a bolt, etc. is arranged between the two short edges on the same side of the two square frames 1, forming a hinge connection between the two square frames 1, so that the two square frames 1 can perform a relative opening and closing action, and the main frame can form an A-shaped structure.

[0024] The bottom supporting plate 2 is arranged at the short edge position on the other side of the two square frames 1, and when the main frame is unfolded, the two ends of the bottom supporting plate 2 are connected to the two short edges by means of a bolt or the like in a detachable manner, so that the bottom supporting plate 2 supports the main frame to form a fixed A-shaped structure.

[0025] After placing the main frame flat on the ground or other plane in the posture with the bottom supporting plate 2 facing down, the tire can be pushed into the middle part of the two square frames 1, so that the bottom of the tire wheel surface is supported on the bottom supporting plate 2, and the inner side walls of the two square frames 1 support and limit the side surface of the tire, ensuring stable placement of the tire in the main frame, and then inflation operation can be performed.

[0026] Anti-skid cushioning rubber pads 11 are further arranged on the inner side walls of the two sides of the square frame 1, which contact the side surface of the tire and increase the friction force, preventing the tire and the rim from slipping during the inflation process, and also providing effective cushioning for the tire rim in the event of accidental explosion, reducing the risk.

[0027] Two rollers 21 are arranged side by side on the bottom supporting plate 2 at a set distance, and after the tire is pushed into the main frame, the bottom of the tire is clamped between the two rollers 21, which not only provides stable placement but also allows the tire to rotate easily, thereby facilitating the user to quickly adjust the position of the tire valve, greatly improving work efficiency.

[0028] Further, the protection frame of the embodiment is preferably in a vehicle-mounted form, so that the foldable protection frame is stored in the trunk of the vehicle and is transported with the vehicle, and is unfolded and arranged from the trunk when needed.

[0029] The protection frame further comprises a U-shaped folding frame 3, the left and right arms at the opening of the U-shaped folding frame 3 are hingedly connected with one of the square frames 1, and specifically, the ends of the arms are respectively hingedly connected to the middle portions of the two long sides of the square frame 1, and the opening of the U-shaped folding frame 3 is in communication with the middle portion of the square frame 1, so that the tire can also enter the U-shaped folding frame 3.

[0030] The U-shaped folding frame 3 and the square frame 1 can be relatively rotated through the hinge, so that the other end of the U-shaped folding frame 3 relative to the opening is arranged as a connection end hingedly connected with the trunk of the vehicle through a hinge or the like, that is, the opening and storage of the main frame can be realized through the everted and inverted of the U-shaped folding frame 3, and in the unfolded state of the main frame, as shown in Figure 2 , the U-shaped folding frame 3 forms a certain angle with the square frame 1, and in the storage state, as shown in Figure 3 , the two square frames 1 are transversely arranged in the trunk of the vehicle and are stacked on the U-shaped folding frame 3, and further, the square frame 1 is further provided with a directional wheel 12, which abuts against the bottom surface of the trunk in the storage state to form a certain support and protection.

[0031] The U-shaped folding frame 3 further comprises two telescopic arms 31, which are respectively slidably connected and arranged in the two arms of the U-shaped folding frame 3, and the outer end of the telescopic arm 31 is hingedly connected with the square frame 1, so that the main frame can be lengthened in the set range from the vehicle when unfolded and arranged, so as to have more space to arrange the tire.

[0032] Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.
