Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile spare tire mounting rack. Background Art

[0002] There are generally two types of spare tires, full-size spare tires and non-full-size spare tires. The full-size spare tire is exactly the same size as the existing tire and can directly replace any tire on the vehicle. In order to install and fix the spare tire on the car, a spare tire mounting rack is required. The spare tire mounting rack in the prior art has some disadvantages in actual use. For example, the overall structural strength of the spare tire mounting rack is poor, the load-bearing capacity is low, and the contact area between the spare tire mounting rack and the spare tire is small. When the car is driving on a bumpy and poor road condition, the spare tire mounting rack will collide and squeeze the spare tire more seriously, and sometimes even damage the spare tire. Among them, the spare tire mounting rack and the car with application number "CN201920524383.0" When the spare tire mounting rack is in use, the auxiliary supporting column group and the supporting member arranged on the main supporting column group are respectively in contact with the wheel hub and the tire in the spare tire of the automobile, thereby increasing the contact area between the spare tire mounting rack and the spare tire of the automobile and alleviating the problem of collision and squeezing of the spare tire of the automobile; and the auxiliary supporting column group can also improve the structural strength of the main supporting column group, thereby improving the bearing capacity of the spare tire mounting rack of the automobile, but there is still some room for improvement in the use of the spare tire mounting rack: since the auxiliary supporting column group on the main supporting column group is of fixed size, the spare tire mounting rack can only be applied to spare tires of one size, which is the same as most spare tire mounting racks on the market, so that the spare tire rack cannot be adjusted according to the spare tire sizes of different car models, reducing the scope of application of the spare tire mounting rack. Utility Model Content

[0003] The utility model aims to provide a spare tire mounting rack for automobiles, so as to solve the problem that the spare tire mounting rack proposed in the above-mentioned background technology can only be applied to spare tires of one size, which is the same as most spare tire mounting racks on the market, so that the spare tire mounting rack cannot be adjusted according to the spare tire sizes of different car models, thereby reducing the application range of the spare tire mounting rack.

[0005] Wherein: a support rod is fixedly installed inside the placement cylinder, a spare tire is placed inside the placement cylinder, and the support rod is inserted in the middle of the spare tire;

[0006] The fixing mechanism comprises a gear ring rotatably mounted on the inner wall of the placement cylinder, the surface of the gear ring is meshedly connected with a plurality of racks, one end of the rack is fixedly connected with a fixing block, the fixing block is in an arc-shaped structure, a rocker is rotatably mounted on the back of the placement cylinder, and the rocker is transmission-connected with the gear ring;

[0007] The mounting mechanism comprises a mounting bracket fixedly mounted on the back of the placing tube, a mounting hole is opened on the surface of the mounting bracket, and a mounting bolt is inserted and connected inside the mounting hole.

[0008] As a preferred solution of the utility model: a mounting box is installed on the back of the placement cylinder, one end of the rocker arm is inserted into the interior of the mounting box and a worm is fixedly installed thereon, a transmission rod is connected to the middle of the gear ring, one end of the transmission rod extends into the interior of the mounting box and a worm wheel is fixedly installed thereon, and the worm is meshingly connected with the worm wheel.

[0009] As a preferred solution of the utility model: a guide rail is fixedly installed on the inner wall of the placement cylinder, a sliding block is fixedly installed on the bottom of the rack, and the sliding block is slidably installed on the surface of the guide rail.

[0010] As a preferred solution of the utility model: both ends of the guide rail are fixedly connected to limit blocks.

[0011] As a preferred solution of the utility model: a protective cover is hingedly installed on the surface of the placement tube, a lock buckle is installed on the surface of the protective cover, a hook is installed on one side of the placement tube, and the lock buckle is hung on the surface of the hook.

[0012] As a preferred solution of the utility model: a thread groove is provided on the surface of the support rod, and a locking cap is threadedly connected to the surface of the thread groove.

[0013] As a preferred solution of the utility model: a sealing ring is installed on the edge of the placement tube.
