The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
 Please refer to Figure 1-4 , the present invention provides a technical solution: a product packaging box, comprising a box body 1, a partition frame 2, a partition frame 3 and a box cover 4, and the partition frame 2 includes two transverse partitions 201 and four vertical partitions 203, The top of the transverse partition plate 201 is provided with four linearly arranged first bayonet openings 202, and the bottom of the vertical partition plate 203 is provided with two second bayonet openings 204. The first bayonet openings 202 on the two transverse partition plates 201 are respectively The spacer frame 3 includes a rectangular frame 301. A rectangular plate 303 is fixedly installed on the inner wall of the rectangular frame 301. The rectangular plate 303 is provided with a plurality of rectangular arrays. The round hole 304, the invisible handle 5 is fixedly installed on both sides of the box body 1, the invisible handle 5 includes a rectangular block 501, the rectangular block 501 penetrates the box body 1, the rectangular block 501 is provided with two sliding holes 502, the two sliding holes The same curved handle 503 is slidably installed in the 502. The curved handle 503 passes through the two sliding holes 502. The two ends of the curved handle 503 close to the partition frame 2 are fixedly installed with baffles 504. The sides are fixedly installed with springs 505, one end of the two springs 505 away from the partition frame 2 is fixedly connected with the rectangular block 501, and the two springs 505 are both slidably sleeved on the curved handle 503;
 Specifically, two curved handles 503 are provided on the same side of the box body 1, and the two curved handles 503 are respectively disposed near the upper end and the lower end of the box body 1; the two ends of the diaphragm 201 are T-shaped structures; The baffle 504 is provided with a trapezoidal groove 506, the trapezoidal groove 506 is used for slidingly inserting the end of the diaphragm 201, and the opening size of the trapezoidal groove 506 is one third of the size of the bottom edge of the groove; the trapezoidal groove 506 An arc-shaped protrusion 507 is provided on the bottom edge of the groove of the diaphragm; the T-shaped structure of the diaphragm 201 is provided with a matching arc-shaped groove 508 corresponding to the arc-shaped protrusion 507; the diaphragm 201 is made of elastic rubber production.
 During the working process, when the packing box is being transported on the transport vehicle, the insertion of the diaphragm 201 and the baffles 504 on the curved handles 503 on both sides is used, and the elasticity of the diaphragm 201 itself and the spring 505 is used. , so that the diaphragm 201 is tensioned in the box body 1 and the two side walls of the box body 1 are tightened, so that the side walls can be closely attached to the force point in contact with the partition frame 2 and the spacer frame 3, thereby ensuring packaging. In the process of stacking and transporting the boxes, the stability of the packaging box itself can avoid the problem of deformation and damage caused by bumps in the packaging box during transportation; The internal structure for stabilizing the goods is tensioned to avoid damage to the transported goods due to shaking; moreover, since the diaphragm 201 is made of rubber, it has the effect of buffering and shock absorption, and can be reused, in line with the current environmental protection policy, reducing Environmental pollution caused by paper products in the prior art;
 When the packing box is individually unloaded and transported by manpower, if the items transported in the packing box are light, just lift the bent handle on the upper part of the box to lift and transport, if the items transported in the packing box are heavier At the time, the arm can be passed through the curved handle on the upper part of the box body, and the hand can be lifted by the curved handle 503 on the lower part of the box body. On the one hand, the stability of transportation is increased; The upper curved handle is pulled out at the same time, using the elasticity of the diaphragm 201 itself and the spring 505, so that the dividing frame 2 and the box body are lifted together as a whole, so that the dividing frame 2 shares the box body 1 by the bending handle 503. Pulling strength, so as to avoid the problem of the box being torn when transporting light items or heavy items, thereby ensuring the safety of transportation. For the packing box with holes, it can ensure the stability and safety of transportation, and can be reused.
 In addition, when the packaging box is used repeatedly, and the user wants to use the packaging box to transport too many items, in order to avoid excessive tensioning of the inner transverse partition 201, the entire partition frame 2 will be deformed excessively. In the case of damage to the item, the T-shaped structure at the end of the diaphragm 201 is deformed in the trapezoidal groove to generate an expansion and contraction allowance, which can not only ensure the stability of the item to be transported by the packaging box, but also ensure the transport safety within a certain range. Improve the usability of the box.
 the present invention, such as Figure 1-4 As shown, the material of the partition frame 2 and the partition frame 3 is the buffer plate 6, the buffer plate 6 includes two clamping plates 601, a corrugated buffer strip 602 is fixedly installed between the two clamping plates 601, and the buffer strip 602 is fixedly installed with A plurality of buffer tubes 603 are arranged linearly.
 The top and bottom of the rectangular frame 301 are provided with a plurality of third bayonet openings 302 in a linear arrangement, and the transverse partition plate 201 and the vertical partition plate 203 are respectively clamped with the corresponding third bayonet openings 302 .
 A plurality of ventilation holes in a rectangular array are opened on the surrounding inner walls of the box body 1 .
 Both inner walls of the box body 1 are provided with rectangular holes, and the two rectangular blocks 501 are respectively fixedly connected to the inner walls of the corresponding rectangular holes.
 The spring 505 is slidably sleeved with a bellows tube, and two ends of the bellows tube are fixedly connected to the rectangular block 501 and the baffle 504 respectively.
 A sound-absorbing washer is fixedly installed in the sliding hole 502, and the curved handle 503 penetrates through the sound-absorbing washer and is slidably connected to the inner wall of the sound-absorbing washer.
 Specifically, the present invention has the effect of separating the products in the packaging box, thereby preventing adjacent products from contacting each other, so that the products can be better protected, and at the same time, it is more convenient to carry.
 Working principle: When packaging the product, put the partition frame 2 into the box body 1, and then place the product in the space separated by the horizontal partition 201 and the vertical partition 203, so as to avoid the possibility of two adjacent products. contact with each other, then place the spacer frame 3 above the spacer frame 2, and then put another spacer frame 2 on the spacer frame 3 to prevent more products, and can effectively prevent the upper and lower products. Contact, when transporting the packaging box containing the product, the two bending handles 503 can be pulled in the direction away from each other, and then the packaging box can be transported through the two bending handles 503, and when transporting the packaging box, The two curved handles 503 will approach each other under the driving of the corresponding spring 505, so that the two curved handles 503 will be accommodated in the box body 1, and the two curved handles 503 will not affect the phase when the box is being transported. adjacent box.
 The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. The equivalent replacement or change of the inventive concept thereof shall be included within the protection scope of the present invention.
