Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, and in particular to a multi-layer shockproof packaging box. Background Technology

[0002] Multi-layer shockproof packaging is a type of packaging specifically designed to protect fragile items or electronic products from damage caused by vibration and impact during transportation. This type of packaging typically employs a variety of materials and structural designs to absorb and disperse impact energy.

[0003] A search revealed Chinese patent publication number CN222248433U, which discloses a multi-layer shockproof packaging box for electronic products. This patent utilizes the rotation of the box lid to drive the back panel of the box to move synchronously. As the back panel moves towards the side panel of the box, it applies force to the support plate and pushes the support plate to move synchronously. The closed top panel of the box can apply pressure to the side push plate, causing the side push plate to move closer to the electronic product, thereby further clamping the electronic product. This device has certain problems: when the product corners are fixed by rubber bands and elastic ropes, vibrations during the transportation of products of different sizes may cause the electronic product to shake and shift. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer shockproof packaging box in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A multi-layer shockproof packaging box includes a main box, symmetrical side panels on both sides of the main box, an anti-bending plate between the symmetrical side panels, the anti-bending plate being located on the bottom wall of the main box, and a limiting mechanism on the side panels, the limiting mechanism including two connecting plates.

[0007] The connecting plate is hinged to the side plate. The two connecting plates are V-shaped with their tips away from the anti-bending plate. A limiting groove is opened on the connecting plate. Multiple grooves are opened on the side of the side plate away from the anti-bending plate. The multiple grooves are arranged at equal intervals. A snap-fit ​​plate is hinged to the side of the limiting groove near the groove. The snap-fit ​​plate is inserted into the groove. A rubber strip is fixed on the inner wall of the limiting groove.

[0009] Preferably, the front end of the main body box has two slots, which are symmetrically distributed on both sides of the main body box, and the slots on the same side correspond to the plug-in plate.

[0010] Preferably, the top cover is fixedly connected with multiple fixing strips, which are T-shaped and arranged at equal intervals. Two sets of buffer components are slidably connected to the fixing strips.

[0011] Preferably, the buffer assembly includes two sliding blocks, and an elastic plate is fixedly connected between the two sliding blocks. The elastic plate is arc-shaped with its opening facing the upper cover.

[0012] Preferably, multiple anti-slip strips are fixed on the side of the elastic plate away from the sliding block, and the multiple anti-slip strips are arranged at equal intervals along the arc surface of the elastic plate.

[0013] Preferably, multiple rubber blocks are fixed on the anti-bending plate. The rubber blocks are hollow arched structures and are arranged at equal intervals.

[0014] The beneficial effects are as follows: by rotating the connecting plate, the four corners of the electronic product are locked in the limiting groove. The rubber strip in the limiting groove protects the surface of the electronic product. Then, the rotation angle of the connecting plate is adjusted according to the size of the electronic product, and the locking plate is inserted into the corresponding groove, thereby stably limiting the electronic product between multiple limiting grooves.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a multi-layer shockproof packaging box includes a main box 101, with symmetrical side panels 302 on both sides of the main box 101, and an anti-bending plate 301 between the symmetrical side panels 302. The anti-bending plate 301 is located on the bottom wall of the main box 101, and a limiting mechanism is provided on the side panels 302. The limiting mechanism includes two connecting plates 401.

[0027] The connecting plate 401 is hinged to the side plate 302. The two connecting plates 401 are V-shaped with their tips away from the anti-bending plate 301. A limiting groove 402 is provided on the connecting plate 401. Multiple grooves 403 are provided on the side of the side plate 302 away from the anti-bending plate 301. The multiple grooves 403 are arranged at equal intervals. A snap-fit ​​plate 404 is hinged to the side of the limiting groove 402 near the groove 403. The snap-fit ​​plate 404 is inserted into the groove 403. A rubber strip 405 is fixed on the inner wall of the limiting groove 402. When in use, the electronic product is placed on the anti-bending plate 301. Then, the connecting plate 401 is rotated to snap the four corners of the electronic product into the limiting groove 402. The rubber strip 405 in the limiting groove 402 protects the surface of the electronic product. Then, the rotation angle of the connecting plate 401 is adjusted according to the size of the electronic product. Then, the snap-fit ​​plate 404 is inserted into the corresponding groove 403, thereby stably limiting the electronic product between the multiple limiting grooves 402.

[0028] The rear end of the main body box 101 is rotatably connected to a rear plate 102, and a top cover 103 is rotatably connected to the rear plate 102. A front baffle 201 is rotatably connected to the end of the top cover 103 away from the rear plate 102. Symmetrical plug-in plates 202 are fixed on both sides of the front baffle 201.

[0029] Two slots 203 are provided at the front end of the main body box 101. The two slots 203 are symmetrically distributed on both sides of the main body box 101. The slots 203 on the same side correspond to the plug-in plate 202. Rotate the top cover 103 to the top of the main body box 101, and then rotate the front baffle 201 so that the plug-in plate 202 is inserted into the slot 203.

[0030] Multiple fixing strips 501 are fixedly connected to the top cover 103. The fixing strips 501 are T-shaped and are arranged at equal intervals. Two sets of buffer components are slidably connected to the fixing strips 501.

[0031] The buffer assembly includes two sliding blocks 502, and an elastic plate 601 is fixedly connected between the two sliding blocks 502. The elastic plate 601 is arc-shaped with its opening facing the upper cover 103.

[0032] Multiple anti-slip strips 602 are fixed on the side of the elastic plate 601 away from the sliding block 502. The multiple anti-slip strips 602 are arranged at equal intervals along the arc surface of the elastic plate 601. During packaging, the position of the sliding block 502 is adjusted according to the distance between the electronic product and the top cover 103, so that the two elastic plates 601 appropriately squeeze the upper surface of the electronic product through the anti-slip strips 602, thereby limiting the electronic product in the vertical direction.

[0033] Multiple rubber blocks 7 are fixed on the anti-bending plate 301. The rubber blocks 7 are hollow arched structures. The multiple rubber blocks 7 are arranged at equal intervals. Electronic products are placed on the rubber blocks 7 so that the electronic products come into contact with the rubber blocks 7.

[0034] Working principle: When in use, place the electronic product on the rubber block 7 so that the electronic product abuts against the rubber block 7. Then rotate the connecting plate 401 to lock the four corners of the electronic product into the limiting grooves 402. The rubber strips 405 in the limiting grooves 402 protect the surface of the electronic product. Then adjust the rotation angle of the connecting plate 401 according to the size of the electronic product. Then insert the snap-fit ​​plate 404 into the corresponding groove 403 to stably limit the electronic product between multiple limiting grooves 402. During packaging, adjust the position of the sliding block 502 according to the distance between the electronic product and the top cover 103 so that the two elastic plates 601 appropriately press the upper surface of the electronic product through the anti-slip strips 602 to limit the electronic product in the vertical direction. Then rotate the top cover 103 to the top of the main box 101, and then rotate the front baffle 201 to insert the plug-in plate 202 into the slot 203.
