[0002] Tire racks effectively protect tires from external pressure, deformation, or tread wear, improving storage efficiency while saving space and cost, and facilitating management and use. However, current tire rack locking operations require moving the side racks upwards and then folding them flat, resulting in a physically demanding and inconvenient locking process. Consequently, the side racks of the tire rack are less secure during folding; and for tire racks designed for easy folding, their stability is low when unfolded.

[0003] In view of this, we propose a foldable tire rack with a locking mechanism to solve the existing problems. Utility Model Content

Each side rod is provided with a U-shaped frame on the side facing the other side rod of the same side frame. The U-shaped frame and the U-shaped groove are interlocked. The top of the U-shaped frame is higher than the top of the U-shaped groove. Each side frame is provided with a locking stop rod. The two ends of each locking stop rod are respectively located in the two U-shaped frames of the corresponding side frame. Each U-shaped frame is provided with a limiting rod at the top.

[0006] Furthermore, the two side rod bases corresponding to each side frame are fixedly connected by connecting rods, the two side rods corresponding to each side frame are fixedly connected by several crossbars, and the tops of the two side rods corresponding to each side frame are fixedly connected by fixing rods.

The foldable tire rack body includes a base frame 1 and two side frames 2. The locking mechanism includes a locking fixing body 3, a locking moving rod 301, and a side frame rotating shaft 302. A side rod base 101 is fixedly connected to each of the four corners of the base frame 1. A locking fixing body 3 is provided above each side rod base 101, and a side rod base 101 is nested at the bottom of each locking fixing body 3. The two side rod bases 101 corresponding to each side frame 2 are fixedly connected by a connecting rod 102. Each connecting rod 102 has several support grooves 107 at the center of one side facing the other connecting rod 102, and the support grooves 107 are provided at the same height as the side rod base 101 and the connecting rod 102. The base frame 1 has several long rods 103 and several reinforcing rods 104 inside, with the long rods 103 and reinforcing rods 104 perpendicular to each other, and the base frame 1 is fixedly connected to the long rods 103 and reinforcing rods 104. The upper surface of the base frame 1 has a placement position 105, within which several support rods 106 are placed, and the support rods 106 are parallel to the long rods 103. Each side frame 2 has a side rod 201 on its left and right sides. The two side rods 201 corresponding to each side frame 2 are fixedly connected by several crossbars 202, and the tops of the two side rods 201 corresponding to each side frame 2 are fixedly connected by fixing rods 203. Each side frame 2 has several support grooves 107 at the center of the side of the crossbar 202 facing the other side frame 2, and the support grooves 107 are located at the same height as the side frame 2 and the crossbar 202. The reinforcing rod 104 is parallel to the connecting rod 102, the crossbar 202, the fixing rod 203, and the locking stop rod 301.

[0025] like Figure 2 As shown, each side frame 2 has two locking and fixing bodies 3 with grooves 303 on the side facing the other side frame 2. Each locking and fixing body 3 is rotatably connected to the side rod base 101 at the groove 303 via the side frame rotation shaft 302. The bottom of each side rod 201 is fixedly connected to the corresponding side frame rotation shaft 302 via a pad 304. The top of the locking and fixing body 3 connected to the bottom of each side rod 201 is provided with a U-shaped groove 305 on the side facing the other side rod 201 of the side frame 2. Each side rod 201 is provided with a U-shaped frame 306 on the side facing the other side rod 201 of the side frame 2. The U-shaped frame 306 and the U-shaped groove 305 are interlocked. The top of the U-shaped frame 306 is higher than the top of the U-shaped groove 305. Each side frame 2 is provided with a locking stop rod 301. The two ends of each locking stop rod 301 are respectively provided in the two U-shaped frames 306 of the corresponding side frame 2. Each U-shaped frame 306 is provided with a limiting rod 307 at the top.

[0026] The working principle of a foldable tire rack with a locking mechanism based on Embodiment 1 is as follows:

[0027] Foldable tire rack in unfolded state, such as Figure 1 As shown, the locking mechanism in the locked state is as follows: Figure 2 As shown, the locking rod 301 is locked under gravity. Manually lifting the locking rod 301 disengages it from the locking and fixing body 3. Once the height of the locking rod 301 is higher than the top height of the U-shaped groove 305, and the limiting rod 307 prevents the locking rod 301 from disengaging from the U-shaped frame 306, the side frame 2 is manually folded inwards. The locking and fixing body 3 folds inwards around the side frame's rotation axis 302. Due to the interlocking connection between the U-shaped frame 306 and the U-shaped groove 305, the locking and fixing body 3 drives the side rod 201 to fold inwards, thus folding the side frame 2 inwards and placing it flat on the upper surface of the base frame 1, thereby completing the folding operation of the side frame 2. Figure 3 As shown. Conversely, by performing the opposite operation, the deployment and locking of side frame 2 can be completed. For example... Figure 4 As shown, both ends of the support rod 106 are placed in the support groove 107 to facilitate multi-layer storage of tires.

[0028] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
