[0028] See attached document Figure 1-3 A combined material rack with a guide locking structure includes a frame structure 1, a pull rod 2 rotatably connected to one side of the frame structure 1, and a material plate structure 3 rotatably connected inside the frame structure 1. The number of material plate structures 3 is set to multiple, and the multiple material plate structures 3 are symmetrically distributed on both sides of the vertical center line of the frame structure 1.

[0029] Frame structure 1 includes a bottom support frame 101 and side support frames 105. The bottom support frame 101 has first insertion holes 104 on both sides of its top, and the side support frames 105 have first bolt holes 106 on both sides of their bottom. A first connecting ring 107 is provided at the bottom of each bolt hole 106. The connection position between the first connecting ring 107 and the side support frame 105 is arc-shaped. The outer wall of the first connecting ring 107 fits against the inner wall of the first insertion hole 104. A first fixing bolt 108 is provided between the two side support frames 105, and a top bracket 111 is provided between the two side support frames 105. Side plates 112 are provided at both ends of the top bracket 111, and second bolt holes 113 are provided at both ends of the side plates 112. A second connecting ring 114 is provided at the bottom of the second bolt hole 113, and the outer wall of the second connecting ring 114 is connected to a second insertion hole 110. A second fixing bolt 115 is provided between the second connecting ring 114 and the second insertion hole 110. When assembling the bottom support frame 101, side support frame 105, and top bracket 111, the first connecting ring 107 is inserted into the first insertion hole 104, and then the first fixing bolt 108 is inserted into the first bolt hole 106, with one end of the first fixing bolt 108 engaging with the thread inside the first insertion hole 104. During the rotation of the first fixing bolt 108, the side support frame 105 moves downwards as a whole. Then, the diameter of the connection point between the first connecting ring 107 and the side support frame 105 is larger than the diameter of the first insertion hole. The diameter of 104 causes the side support frame 105 to move the first connecting ring 107 downwards, pressing the top of the first connecting ring 107 into the interior of the first insertion hole 104, thus installing the side support frame 105 into the bottom support frame 101 for a tight connection. The connection between the second connecting ring 114 and the second insertion hole 110 inside the side plates 112 at both ends of the top bracket 111 is also the same as the connection between the first connecting ring 107 and the first insertion hole 104, thereby installing the top bracket 111 between the two side support frames 105.

[0030] Furthermore, the bottom support frame 101 is provided with casters 102 at the four corners of the bottom, and U-shaped strips 103 are provided on both sides of the bottom of the bottom support frame 101. The side support frame 105 is provided with limit strips 109 on both sides. The top of the side support frame 105 is provided with a second insertion hole 110. The frame structure 1 can be raised and lowered as a whole by a forklift through the U-shaped strips 103. At the same time, the casters 102 are used to pull the frame structure 1 to move.

[0031] Furthermore, the material plate structure 3 includes a vertical frame 301 and a material plate body 304. The vertical frame 301 is disposed inside the side support frame 105. Mounting blocks 302 are provided on both sides of the vertical frame 301. A spring tension rod 303 is rotatably connected to the outer wall of the mounting block 302. The material plate body 304 is rotatably connected to the outer wall of the vertical frame 301. A connecting plate 305 is provided at the bottom of the material plate body 304. The connecting plate 305 is rotatably connected to the spring tension rod 303. When material is placed on the top of the material plate body 304, the spring tension rod 303 pulls the material plate body 304 to rotate, so that the bottom of the material plate body 304 fits against the limiting strip 109, keeping the material plate body 304 horizontal.

[0032] The material racks currently in use are all welded as a whole, which increases transportation costs. However, in this application, by connecting the frame structure 1, the tie rod 2, and the material plate structure 3, the frame structure 1, the tie rod 2, and the material plate structure 3 can be transported to the location separately before assembly, thereby reducing the cost of transporting the material racks.

[0033] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
