[0028] Example 1: As shown in the attached document Figure 1-3 The present invention relates to a novel modular assembly transport rack, medium size, comprising a chassis frame 1 with a length of 1800mm and a width of 1450mm, and four adjustable universal brackets 2 that can be detached and installed on the chassis frame 1.

[0029] like Figure 3 As shown, in this embodiment, the chassis frame 1 includes an inner plane frame assembled by staggered insertion of two longitudinal inner rods 11 and eight transverse inner rods 12, an outer frame surrounding and connected by insertion around the inner plane frame, and four stacking feet 13 fixed to the corners of the outer frame.

[0030] The structure of the outer frame: such as Figure 1As shown, the outer frame is a quadrilateral frame formed by two opposing longitudinal side bars 14 and two opposing transverse side bars 15. Each stacking foot 13 has a receiving slot 13a, as shown. Figure 7 As shown, the ends of adjacent longitudinal side bars 14 and transverse side bars 15 are joined by tenon and mortise joints in the horizontal direction, as... Figure 1 As shown, the joint is inserted into the receiving groove 13a, and then the stacking foot positioning screw extends upward from the bottom of the stacking foot 13 into the receiving groove 13a, thereby fixing the tenon joint between the ends of the longitudinal side bar 14 and the transverse side bar 15 and the stacking foot 13. Alternatively, other methods can be used, such as installing two rotating buckles on the stacking foot 13, which are respectively fastened into the corresponding longitudinal side bar 14 and transverse side bar 15 when locked.

[0031] The structure of the inner plane frame: two longitudinal inner rods 11 are arranged in parallel and are used to assemble and connect between two opposite transverse side rods 15. Eight transverse inner rods 12 are staggered and distributed in parallel between the two longitudinal side rods 14 and the two longitudinal inner rods 11. Specifically, three transverse inner rods are distributed between the longitudinal side rods 14 and the longitudinal inner rods 11, and two transverse inner rods are distributed between the two longitudinal inner rods 11.

[0032] The plug-in assembly method of the inner plane frame: such as Figure 5 , 6 As shown, two longitudinal inner rods 11 are assembled and connected between two opposite transverse side rods 15. The two ends of the longitudinal inner rods 11 each have longitudinal inner rod keys. The longitudinal inner rod keys include an outwardly protruding longitudinal rod multi-sided frustum 11a and a longitudinal rod column 11b formed by the longitudinal rod multi-sided frustum 11a protruding outward. The transverse side rods 15 have longitudinal rod key through holes 11c that match the shape of the longitudinal inner rod keys and penetrate through them.

[0033] Multiple transverse inner rods 12 are respectively assembled and connected between the longitudinal side rod 14 and the longitudinal inner rod 11, as well as between two longitudinal inner rods 11. Each transverse inner rod 12 has transverse inner rod keys at both ends. The transverse inner rod keys include a transverse polyhedron 12a protruding outward and a transverse column 12b formed by the transverse polyhedron 12a protruding outward. The longitudinal side rod 14 and the longitudinal inner rod 11 each have transverse key through holes 12c that match the shape of the corresponding transverse inner rod keys and penetrate through them.

[0034] In this embodiment, there are also multiple positioning bolts that can respectively cooperate with the longitudinal rod 11b and the transverse rod 12b, so as to facilitate the assembly process. For example, after one end of the transverse inner rod 12 is inserted into the corresponding longitudinal inner rod 11, the positioning screws are screwed into the transverse rod 12b to prevent it from separating from the longitudinal inner rod 11. This makes the assembly between the transverse inner rod 12 and the longitudinal inner rod 11, the longitudinal side rod 14, and the longitudinal inner rod 11 and the transverse side rod 15 faster and the fit more stable and firm.

[0035] In this embodiment, each universal bracket 2 is installed between the inner plane frame and the outer frame. The universal bracket 2 directly contacts the heavy object, thereby distributing the weight of the heavy object to the entire chassis frame 1, so that each member of the chassis frame 1 is evenly stressed, more stable, and the members of the chassis frame 1 are not easily damaged.

[0036] Each universal bracket 2 is 720mm long and 575mm wide.

[0037] like Figure 4 As shown, the transport rack also includes four peripheral baffle structures 3 that are detachably mounted on the corresponding universal brackets 2 and are adjustable in position; eight pads 4 that are detachably mounted on the corresponding universal brackets 2 and are adjustable in position; and four anti-jumping mechanisms 5 that are detachably mounted on the corresponding universal brackets 2 and are adjustable in position.

[0038] The perimeter barrier structure is fixed and modularized into various angle shapes to block the edge contours of goods of different shapes, and to position the central goods in front, behind, left, and right to prevent them from tipping over.

[0039] The anti-jump mechanism 5 is telescopic, including a lower anti-jump part installed at the corresponding position on the universal bracket 2, an upper anti-jump part that can slide up and down and is positioned by a pin engaging with a corresponding hole, and an anti-jump stop bolt that is slidably set on the upper anti-jump part. The height of the upper anti-jump part is determined by the pin being inserted into the corresponding hole, so that the anti-jump stop bolt can press against the upper surface of the goods when it is extended, preventing the goods from jumping upward during transportation.

[0040] Based on the shape, size, and stress points of the goods, install the pad 4 at the corresponding position on the universal bracket 2 and fix it with screws.

[0041] Installation method: First, insert and assemble two transverse inner rods 12 between one side of two longitudinal inner rods 11. Then, insert and assemble the remaining 6 transverse inner rods 12 on the other side of the two longitudinal inner rods 11. Then, insert two longitudinal side rods 14 and two transverse side rods 15 around the inner plane frame in sequence. Make mortise and tenon joints between the ends of each adjacent longitudinal side rod 14 and transverse side rod 15, and then fix them to the corresponding stacking feet. This completes the installation of the chassis frame 1. Finally, fix the universal bracket 2 to the chassis frame 1 with screws. Then, install the peripheral baffle structure 3, pad block 4 and anti-jump mechanism 5 on the universal bracket 2 at the corresponding positions according to the actual transportation requirements.

[0042] Example 2: Figure 8 As shown, the difference between this embodiment and embodiment one is that the chassis frame of embodiment two is a smaller size, with a length of 1440mm and a width of 1150mm.

[0043] Example 3: Figure 9As shown, the difference between this embodiment and embodiment one is that the chassis frame in embodiment three is a larger size, with a length of 2290mm and a width of 1760mm.

[0044] It should be noted that the universal brackets installed in the three embodiments are of uniform standard size, which is more conducive to saving production costs and can also be disassembled and reused on chassis frames of various models and sizes as needed.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
