Description

Technical Field

[0001] The present invention relates to the technical field of packaging boxes, and in particular to a packaging box with adjustable spacing between bracket groups and a use method thereof. Background Art

[0002] Packing boxes are mainly used to load large mechanical products to facilitate the transportation of these products. Currently, the sizes of common packing boxes on the market are different, and they are used to transport products of different specifications. Large packing boxes can hold smaller products, but small packing boxes cannot hold larger products. In addition, due to the large size and weight of these products, it is often necessary to set brackets in the packing boxes to provide sufficient fixation and support for the products.

[0003] Previously, our company has developed a series of packaging boxes with different functions, such as CN221478308U, CN221395223U, CN221438538U, CN111874467B, etc. Most of these packaging boxes can only carry goods of specific sizes. Since the brackets and baffles cannot be moved, when the size and specifications of the product change, it is necessary to replace the corresponding model of special packaging boxes, resulting in low versatility and utilization of the packaging boxes, and also increasing the transportation cost of the products. Summary of the invention

[0004] One of the purposes of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide a packaging box with adjustable spacing between support groups, which includes a packaging box bottom plate, a support group, a track, and a blocking mechanism. The track is fixed on the packaging box bottom plate along the length direction of the packaging box. The support group includes at least two supports, which are also dispersedly arranged along the length direction of the packaging box, at least one of which is fixed on the track and can slide along the track. The blocking mechanism is arranged on the outside of the left and right end support, and is used to fix the product to prevent it from moving horizontally.

[0005] Furthermore, the bracket group includes 2-6 brackets, and the brackets are dispersedly arranged in a straight line.

[0006] Preferably, the bracket group includes two brackets, namely a front bracket and a rear bracket.

[0007] Furthermore, the number of the tracks is the same as the number of the brackets, and each bracket is fixed on a set of tracks and can slide along the tracks. By sliding the brackets left and right on the tracks, the distance between different brackets can be conveniently adjusted to adapt to the length of different products and lock them.

[0008] Furthermore, each set of tracks includes two single tracks arranged in parallel, and both ends of the bracket are respectively fixed on the corresponding single tracks and slide along them.

[0009] Furthermore, the packaging box also includes a fixed support seat, which is dispersedly fixed on the bottom plate of the packaging box at a certain distance along the track, and a matching support base is arranged on the support. After the support is adjusted into place, the support base is fixedly connected to the fixed support seat, thereby realizing the connection and locking between the support and the bottom plate of the packaging box.

[0010] Furthermore, the fixed support seats are symmetrically distributed in groups of two on both sides of the single track.

[0011] Furthermore, the blocking mechanism includes a front blocking mechanism and a rear blocking mechanism, wherein the front blocking mechanism is fixed on the bottom plate of the packaging box, and the rear blocking mechanism is fixed on a track corresponding to the rear support and can slide along the track.

[0012] Furthermore, the rear blocking mechanism is fixedly connected to the bottom plate of the packaging box via a fixed support seat.

[0013] Furthermore, track wheels are arranged at the bottom of the front and rear brackets and the rear blocking mechanism, and both slide on the track with the help of the track wheels.

[0014] Furthermore, the rear blocking mechanism also includes a rear blocking adjustment device, which includes an adjustment base, a handwheel, a screw, a limit ring, and a buffer plate, wherein the handwheel and the buffer plate are respectively fixed at both ends of the screw, and the screw is connected to the adjustment base through a screw hole on the adjustment base, and the limit ring is fixed on the screw and is located between the adjustment base and the buffer plate.

[0015] The second object of the present invention is to provide a method for using the above-mentioned packaging box, including: measuring the size of the product to be shipped, adjusting the support and blocking mechanism that can slide along the track to the corresponding position and fixing them accordingly, then hoisting the product onto the support and locking it, and finally covering the packaging box with a lid.

[0016] Compared with existing similar packaging box products, the improved effects of the present invention are mainly reflected in the following points: First, by arranging parallel tracks on the bottom plate of the packaging box, the distance between the support and the blocking mechanism can be quickly adjusted, thereby adapting to the shipping needs of products of different sizes, realizing multiple uses of one box, improving the utilization rate of the packaging box, and reducing costs; second, by distributing fixed support seats on both sides of the track, the support, the blocking mechanism and the bottom plate of the packaging box can be reliably fixed together, and multiple specific fixed positions are formed, which is conducive to the rapid shipping of products; third, the entire device has a simple structure, strong compatibility, low modification cost, and firm product fixation. After promotion and use, it will help enhance the competitiveness of enterprises. BRIEF DESCRIPTION OF THE DRAWINGS

The front track 3 and the rear track 4 each comprise two single tracks of equal length and arranged in parallel, and the front track 3 and the rear track 4 are fixed on the packing box bottom plate 5 one in front of the other in the length direction of the packing box. The front bracket 1 is arranged on the front track 3, and the rear bracket 2 and the rear blocking adjustment device 9 are arranged on the rear track 4. Track wheels 10 are arranged on the left and right sides of the bottom of the front bracket 1, the rear bracket 2, and the rear blocking adjustment device 9. When the track wheels 10 slide on the track, the distance or interval between the front bracket 1, the rear bracket 2, and the rear blocking adjustment device 9 can be adjusted.

[0025] When the front bracket 1, the rear bracket 2, and the rear blocking adjustment device 9 are adjusted to the right position and need to be fixed, the front bracket fixing support seat 7 and the rear bracket fixing support seat 8 come into play. Figure 2As shown, the front bracket fixing support seats 7 are fixed on the bottom plate 5 of the packaging box in groups of two at different intervals along a single track. Screw holes are set on the top of the front bracket, and matching screw holes are set on the front bracket base 11 of the front bracket 1. After aligning the two, insert the screws to lock. In order to ensure the fixing effect, the front bracket 1 is fixedly connected to the bottom plate 5 of the packaging box through at least 4 groups of front bracket fixing support seats 7, and the support of the track wheel 10 enables it to withstand large mechanical products. Figure 3 As shown, the fixing principle of the rear support seat 2 and the rear blocking adjustment device 9 after sliding is the same as that of the front support seat 1, except that the number and position of the fixed support seats are different.

[0026] like Figure 2 As shown, the front blocking seat 6 is located on the left side of the front supporting seat 1, and is fixed on the bottom plate 5 of the packaging box to prevent the front supporting seat 1 and the product from moving to the left.

[0027] like Figure 3-4 As shown, the rear blocking adjustment device 9 is located on the right side of the rear support 2, and there are two of them, and the two have the same structure. The rear blocking adjustment device 9 includes a hand wheel 13, a screw rod 14, a buffer sheet 15, a limit ring 16, and an adjustment base 17. After the screw rod 14 passes through the screw hole on the adjustment base 17, the hand wheel 13 is fixed to the right end, and the buffer sheet 15 is fixed to the left end. The limit ring 16 is welded to the screw rod 14 to prevent the screw rod from excessively moving to the right.
