Description

Technical Field

[0001] The present invention relates to the technical field of packaging boxes, and in particular to a flip-type bracket, a packaging box thereof and a use method thereof. Background Art

[0002] There are often 2-3 groups of brackets in the packaging boxes for large mechanical products. These brackets are fixed on the bottom plate of the packaging box at a certain distance. The products are lifted onto the brackets by a crane and locked. The box lid is closed and the product can be shipped.

[0003] In the prior art, bolts are often used to fix and lock the bracket to the bottom plate of the packaging box, which means that the bracket cannot be moved, so that the packaging box can only be used to transport specific products. Once the shape and size of the product changes, either the packaging box is replaced or the bolts are loosened to move the bracket to another position on the bottom plate of the packaging box and lock it again. Analysis shows that the first solution has the disadvantages of poor versatility, low utilization rate, and high cost of the packaging box, while the second solution has the disadvantages of cumbersome procedures, time-consuming and labor-intensive, etc. In addition, since the metal bracket is heavy, it is necessary to coordinate the participation of a small crane when changing its fixed position, which invisibly increases the cost. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a flip-type bracket, which includes a bracket body 1, a rotating shaft assembly, and a flip assembly. The bracket body 1 is connected to the rotating shaft assembly, and the flip assembly is connected to the bracket body 1 and can push the bracket body 1 to flip around the rotating shaft assembly.

[0005] Furthermore, the flip angle of the bracket body 1 is 90°, that is, the bracket can be transformed from a vertical use state to a horizontal idle state.

[0006] Furthermore, the shaft assembly includes a fixed seat 6 and a shaft 9, and the bracket body 1 is rotatably connected to the fixed seat 6 via the shaft 9. Specifically, a long shaft passes through the bracket body 1 and its two ends are respectively fixed in the fixed seat 6, or two short shafts are respectively fixed on both sides of the bracket body 1, and the two short shafts are then connected to the bracket body 1.

[0007] Furthermore, the rotating shaft 9 is located at the lower middle part of one side of the bracket body 1 .

[0008] Furthermore, the flip assembly includes a connecting rod 2, a slider 3, a handwheel 4, a screw 5, and a bracket 7. The two ends of the screw 5 are respectively fixed on the bracket 7. The handwheel 4 is fixed to the end of the screw 5 and can drive it to rotate. The slider 3 is mounted on the screw 5 and is transmitted through a thread. One end of the connecting rod 2 is fixedly connected to the bracket body 1, and the other end is fixedly connected to the slider 3.

[0009] Furthermore, the connecting rod 2 is fixed to the upper middle portion of one side of the bracket body 1 .

[0010] Furthermore, the screw rod 5 and the rotating shaft 9 are perpendicular to each other but do not intersect, and the screw rod 5 is located above the rotating shaft 9 .

[0011] Further, the flip type bracket also includes a support seat 8, which is located on the side where the flip type bracket falls. When the bracket is flipped horizontally, the support seat with a certain height provides support for it and locks it.

[0012] The second object of the present invention is to provide a packaging box equipped with the above-mentioned flip-type bracket, which includes a packaging box bottom plate and a flip-type bracket. The number of flip-type brackets is at least 2, and these flip-type brackets are dispersedly fixed on the packaging box bottom plate at a certain distance along the length direction of the packaging box.

[0013] Furthermore, the height of the flip-type bracket and its contact surface with the product are the same or different.

[0014] Furthermore, the packaging box also includes at least one non-reversible bracket (excluding the shaft assembly and the reversing assembly), which is fixed to the bottom plate of the packaging box at the end of the packaging box. The non-reversible bracket serves as the main bracket, and the remaining reversible brackets serve as auxiliary brackets, so that only one end of the bracket needs to be adjusted to adapt to different products.

[0015] The third object of the present invention is to provide a method for using the above-mentioned packaging box, including: determining the vertical and horizontal states of each flip-type bracket according to the size of the product to be shipped, operating the flip assembly to put down the bracket to be flipped and lock it, and the remaining brackets remain in a vertical state.

[0016] Compared with the existing similar technologies, the beneficial effects of the present invention are embodied in the following aspects: (1) by changing the horizontal and vertical states of each bracket, it can meet the shipping requirements of products of different shapes and sizes, greatly improving the versatility and utilization rate of the packaging box; (2) the flip-type bracket has a simple structure, low modification cost and good use effect; (3) it can be operated by one person, which not only saves time and effort, but also can complete the switching of the bracket state in a very short time.

[0021] In order to enable ordinary technicians in the field to fully understand the technical solutions and beneficial effects of the present invention, further detailed descriptions are given below in conjunction with specific embodiments and drawings.

[0022] When large mechanical products are shipped in packaging boxes, they are mainly supported and fixed by the main bracket and auxiliary bracket fixed on the bottom plate of the packaging box. When the shape and size of the loaded product changes, the packaging box can be compatible with various types of products by replacing the auxiliary bracket. However, the existing auxiliary bracket replacement process is time-consuming, labor-intensive and inefficient.

[0023] In response to the requirements of speed and convenience, we designed a Figure 1 The new flip type bracket shown. The flip type bracket includes a bracket body 1, a connecting rod 2, a slider 3, a hand wheel 4, a screw 5, a fixed seat 6, a bracket 7, a support seat 8, and a rotating shaft 9. The fixed seats 6 are symmetrically distributed on both sides of the bracket body 1 along the length direction of the bracket and close to its lower right corner. The rotating shaft 9 passes through the bracket body 1 and is connected to the fixed seat 6 at both ends. The bracket 7 is symmetrically distributed on the left side of the bracket body 1 along the width direction of the bracket. The two ends of the screw 5 are respectively fixed on the bracket 7, and the hand wheel 4 is fixed to the left end of the screw 5. The slider 3 is provided with a screw hole, and the screw 5 passes through the screw hole and is confined between the two brackets 7. The two ends of the connecting rod 2 are respectively fixed on the slider 5 and the bracket body 1.

[0024] like Figure 3 As shown, the flip bracket has two use states: vertical and horizontal. In the vertical state, the flip bracket can provide support and fixation for the product, while the horizontal state means that the flip bracket is idle and cannot be used to support and fix the product. The two states are realized as follows: turn the hand wheel 4, and the slider 3 moves to the right along the screw under the action of the thread, and the bracket body 1 is pushed by the connecting rod 2 to rotate 90° around the rotating shaft 9 to the horizontal state. After the bracket body 1 contacts the support seat 8 on the right side, stop turning the hand wheel 4, and use screws to lock the bracket body 1 and the support seat 8.

[0025] We apply the above flip-type bracket to the latest packaging box products. A non-flippable bracket is fixed on the left side of the packaging box as the main bracket, and 2-3 flip-type brackets are scattered at the rear of the packaging box as auxiliary brackets. The fixing base 6 of the flip-type bracket is fixed to the bottom plate of the packaging box by screws. A connection hole is reserved on the other side of the flip-type bracket, and it is fixed to the bottom plate of the packaging box by screws when it is in a vertical state.

[0026] by Figure 2-3For example, the improved packaging box loading method for different products is as follows: Product A needs to use the auxiliary bracket on the right and leave the auxiliary bracket on the left idle. To do this, do not turn the hand wheel to keep the flip bracket on the right vertical, turn the hand wheel to put the flip bracket on the left horizontally and lock it, and then hang the product on the bracket. When the auxiliary bracket on the left needs to be used and the auxiliary bracket on the right is idle, just change the rotating hand wheel.

[0027] The present invention can significantly reduce the time for changing products and loading them into large packaging boxes, shortening the changing process from the original 20-30 minutes to about 5 to 8 minutes, which not only improves the efficiency of the packaging box changing operation, but also saves costs.
