The physical performance indicators of packaging cartons become the basis for their quality evaluation, and the accuracy and reliability of test data require good detection environmental conditions for guarantee.

[0003] However, the following problems still exist in the prior art:

[0004] Firstly, for the packaging carton for fragile items in the prior art, it is not convenient to partition the space inside the box. When multiple fragile items need to be stored, there may be a situation where the fragile items come into contact with each other during handling and cause breakage. Moreover, the structural strength inside the box is limited, and only by placing fillers on the inner wall of the box can the fragile items be supported, and the supporting effect is not good.

[0005] Secondly, for the packaging carton for fragile items in the prior art, it is not convenient to protect and support fragile items of different sizes. Some fragile items are relatively large in volume. In this case, if they are far from the inner wall of the box, it is impossible to ensure a high supporting and protecting effect, and the probability of breakage is relatively high.

[0006] In view of the above problems, the inventor proposes a packaging carton for fragile items to solve the above problems. Content of the Utility Model

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: As Figures 1-3 shown, the present invention provides a packaging carton for fragile items, including a box body 1. A box cover 2 is provided at the upper end of the box body 1. A plurality of clamping plates 4 are fixedly provided on both inner walls of the box body 1. There are four clamping plates 4 on the inner wall of the box body 1, and the four clamping plates 4 are evenly spaced. A clamping groove 41 is opened at the inner end of the clamping plate 4. Two placing plates 42 are provided in the box body 1. The two ends of the placing plate 42 are respectively slidably connected to two corresponding clamping grooves 41. The length of the placing plate 42 is the same as the distance between the two corresponding clamping grooves 41. Contact plates 43 are fixedly provided at both ends of the placing plate 42. Two adjusting plates 5 are provided in the box body 1. The box body 1 is the inner body of the packaging carton. Covering the box cover 2 can improve the protection ability for fragile items. The placing plate 42 can be stuck in the clamping groove 41 on the clamping plate 4. Place the fragile items between the contact plate 43 and the inner wall of the box body 1, and then add protective filling materials. The placing plate 42 can divide the space inside the box, so as to prevent the fragile items from contacting each other. The adjusting plate 5 and the clamping plate 4 protect and support the fragile items inside the box, effectively improving the structural strength inside the box body 1. Moreover, the adjusting plate 5 and the clamping plate 4 can be installed at selected positions according to the situation, which is convenient to use and has high versatility.

[0020] Four positioning columns 21 are fixedly provided at the lower end of the box cover 2. Four positioning grooves 22 for cooperating with the positioning columns 21 are opened at the upper end of the box body 1. Inserting the positioning columns 21 into the positioning grooves 22 facilitates covering the box cover 2.

[0021] Four supporting blocks 3 are fixedly provided at the lower end of the box body 1. Four placing grooves 31 for cooperating with the supporting blocks 3 are opened at the upper end of the box cover 2. The upper box body 1 can be placed in the placing groove 31 on the lower box body 1 through the supporting blocks 3, which makes the stacking of the box body 1 more convenient.

[0022] The inner end of the adjusting plate 5 is fixedly provided with a reinforcing plate 51. The two reinforcing plates 51 are mirror-symmetrically distributed. The cross-sectional shape of the reinforcing plate 51 is U-shaped. On both sides of the outer end of the adjusting plate 5, insertion plates 52 are fixedly provided. The outer end of the insertion plate 52 is movably inserted with a sleeve plate 53. The outer end of the sleeve plate 53 is slidably connected to the corresponding card slot 41. On the upper and lower sides of one end of the sleeve plate 53, fixing members 55 are provided. On the outer end of the fixing member 55, two fixing bolts 56 are provided. The fixing bolts 56 are bolted to the corresponding fixing member 55, sleeve plate 53 and insertion plate 52. On both sides of one end of the insertion plate 52, a plurality of fixing slots 57 for using with the fixing bolts 56 are opened. Place larger fragile items between the two reinforcing plates 51, and then place appropriate filling materials to protect and support the fragile items. The reinforcing plate 51 can improve the limit protection effect on the fragile items. The sleeve plate 53 can be installed on the card plate 4 at a suitable position as needed. The distance between the adjusting plates 5 can be adjusted. Specifically, after inserting the insertion plate 52 into a suitable size in the sleeve plate 53, insert the fixing bolts 56 on the fixing member 55 into the appropriate fixing slots 57 for fixation. In this way, the protection and support effect on fragile items of different sizes can be improved.

[0023] There are six fixing slots 57 on one side of the insertion plate 52, and the six fixing slots 57 are equally spaced, so that there are more adjustable sizes and the versatility is wider.

[0024] Working principle: The box body 1 is the inner body of the packaging carton. Covering the box cover 2 can improve the protection ability for fragile items. The placement plate 42 can be stuck in the card slot 41 on the card plate 4. Place the fragile items between the contact plate 43 and the inner wall of the box body 1, and then add protective filling materials. The placement plate 42 can separate the space inside the box, so as to prevent the fragile items from contacting each other. The adjusting plate 5 and the card plate 4 protect and support the fragile items inside the box, effectively improving the structural strength inside the box body 1. And the adjusting plate 5 and the card plate 4 can be installed at selected positions according to the situation, which is convenient to use and has high versatility;

[0025] Inserting the positioning post 21 into the positioning slot 22 facilitates covering the box cover 2;

[0026] The upper box body 1 can be placed in the placement slot 31 on the lower box body 1 through the support block 3, which makes the stacking of the box body 1 more convenient;

[0027] Place larger fragile items between two reinforcing plates 51, and then place appropriate fillers to protect and support the fragile items. The reinforcing plates 51 can improve the limiting protection effect on the fragile items. The sleeve plate 53 can be installed on the clamping plate 4 at an appropriate position as needed. The distance between the adjusting plates 5 can be adjusted. Specifically, after inserting the plug plate 52 into a suitable size in the sleeve plate 53, fix it by inserting the fixing bolt 56 on the fixing member 55 into a suitable fixing groove 57. In this way, the protection and support effect on fragile items of different sizes can be improved;

[0028] Six fixing grooves 57 enable more adjustable sizes and wider versatility.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these changes and modifications.
