DETAILED DESCRIPTION OF THE EMBODIMENTS

(7) To facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Multiple embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

(8) It should be noted that when an element is described as being fixed on another element, it may be directly on the another element or there may be an intermediate element. When an element is considered to be connected to another element, it may be directly connected to the another element or there may be an intermediate element at the same time. The terms vertical, horizontal, left, right, and similar expressions used in this text are for illustrative purpose only.

(9) Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term and/or used in this text includes any and all combinations of one or more related items listed.

(10) Referring to FIG. 1 to FIG. 5, a multi-purpose spare tire rack includes a fixing frame 1 and a fixing member 2, the fixing frame 1 is provided with a fixing portion 11 and a protruding portion 12, the fixing portion 11 is used for fixation and connection to a vehicle or a wall, the protruding portion 12 is provided with a connecting hole 121, the connecting hole 121 is provided with a limiting hole 122, and the fixing member 2 is inserted into the connecting hole 121 and connected with the limiting hole 122. The fixing member 2 cooperates with the fixing frame 1 to secure a spare tire. The fixing frame 1 and the fixing member 2 can be assembled and disassembled, which solves the technical problem existing in the prior art that the integrated configuration cannot be assembled, disassembled, or replaced, achieves the purpose of quickly replacing the fixing member 2, is suitable for use in fixation of spare tires of different sizes, and involves easy operation.

(11) In the present invention, the connecting hole 121 is a hole for insertion that is wide at its upper part and narrow at its lower part and arranged at the side of the protruding portion 12 and extending to the top of the protruding portion 12 (as shown in FIG. 2) or a circular hole for insertion that is arranged at the top of the protruding portion 12 (as shown in FIG. 5). The end of the hole for insertion is connected to the limiting hole 122. The fixing member 2 includes a first screw rod 21 and a second screw rod 24, and the first screw rod 21 and the second screw rod 24 are both matched with the hole for insertion and the limiting hole 122. The limiting hole 122 is a square hole, and the first screw rod 21 and the second screw rod 24 each are provided with a square column that fits the square hole adjacent to a nut; the first screw rod 21 and the second screw rod 24 each are rotatably connected with a locking nut 23, a wing nut 22, a flat washer 25, an anti-loosening spring washer 26, and a hub nut 27. The locking nut 23, the flat washer 25, and the anti-loosening spring washer 26 are in contact with the protruding portion 12 to lock and fix the square column to fit the square hole. The wing nut 22 is used to secure the spare tire placed on the spare tire rack. The protruding portion 12 of the fixing frame 1 is symmetrically provided with storage holes 123, and the storage holes 123 allow the insertion of the first screw rod 21 and the second screw rod 24. The length of the first screw rod 21 is greater than that of the second screw rod 24. The first screw rod 21 and the second screw rod 24 have the same thread pitch and identical diameter. The arrangement of symmetrical storage holes 123 on the side of the protruding portion 12 addresses the technical problem of space occupation existing in the prior art due to failure of provision of the storage holes 123 for receiving screw rods, which achieves the storage of screw rods and avoids the loss of screw rods.

(12) In the present invention, the fixing portion 11 is provided with a through hole through which a screw is inserted for fixation and installation, which can improve the fixing effect.

(13) The principle of implementing the multi-purpose spare tire rack of the present invention is as follows:

(14) When in use, the screw is passed through the through hole of the fixing portion 11 to be fixedly connected to a vehicle or a wall. The first screw rod 21 and the second screw rod 24 of different lengths are selected according to the thickness of the spare tire. Then, the corresponding first screw rod 21 or second screw rod 24 is inserted into the hole for insertion that is wide at its upper part and narrow at its lower part and slides into the square hole (the corresponding first screw rod 21 or second screw rod 24 is inserted into the circular hole for insertion and slides into the square hole), so that the square column and the square hole are fitted and connected. The locking nut 23 is rotated to lock and fix the square column and the square hole for tight connection to ensure the stability of the connection of the first screw rod 21 or the second screw rod 24. Subsequently, the spare tire is placed on the protruding portion 12 of the fixing frame 1, followed by rotating the wing nut 22 to secure the spare tire.

(15) When not in use, the first screw rod 21 and the second screw rod 24 are inserted into different storage holes 123 to prevent the first screw rod 21 and the second screw rod 24 from falling and being lost.

(16) The above is an exemplary description of the present invention in combination with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned method. Non-substantial improvements made by adopting the methodological concept and technical solution of the present invention or direct use of the methodological concept and technical solution of the present invention to other occasions without modification all fall within the protection scope of the present invention.
