[0021] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] See Figure 1-3This utility model provides a packaging box for cushioning and protecting electronic circuit board testing instruments.

[0023] The packaging box includes a tray 1, a box body, and a top cover 3. The box body consists of four side panels 2, which are connected to each other and to the tray 1 via butterfly buckles. All butterfly buckles are located on the outer surface of the packaging, and a protective block 4 is provided on the outer side of each butterfly buckle. The butterfly buckles connect the side panels 2 to each other and to the tray 1, and the packaging box can be disassembled by unlocking the butterfly buckles after transportation. However, since the tray 1 and side panels 2 are both made of sheet metal and are only connected by butterfly buckles, their impact resistance at the connection points and on the side panels is poor, which cannot adequately guarantee the cushioning and protection of the packaging box for precision electronic circuit board testing instruments.

[0024] Example 1:

[0025] This embodiment provides improvements to the internal structure of the packaging box.

[0026] With the front view of the packaging box as the front side, the back side as the back side, the left and right sides as the left and right sides respectively, the side facing the inside of the packaging box is the inside side, and the side facing the outside of the packaging box is the outside side.

[0027] On the top cover of tray 1, a first limiting seat 6 is provided on the left and right sides respectively. The first limiting seat 9 is located on the rear corner of tray 1. The two bottom sides and the top corner of the rear corner of the first limiting seat 9 are aligned with the two bottom sides and the top corner of the rear corner of tray 1, and the outer side of the first limiting seat 6 abuts against the inner side of the left, right and rear side panels 2. The corner connection between tray 1 and side panel 2 is reinforced.

[0028] Preferably, the first limiting seat 6 includes a plurality of limiting support blocks 6.1 disposed at the bottom and a limiting panel 6.2 disposed on the limiting support blocks 6.1. The limiting panel 6.2 is provided with a limiting enclosure 6.3, which is a concave shape opening inwards. A limiting side plate 6.4 is also provided on the limiting enclosure 6.3, the cross-sectional shape of which is the same as that of the limiting enclosure 6.3, and is also a concave shape opening inwards. The outer surface of the limiting side plate 6.4 abuts against the inner surface of the side plate 2. At least one limiting support block 6.1 in the first limiting seat 6 is disposed at a corner of the tray 1. An L-shaped buffer pad is provided on the inner side of the concave corner of the limiting enclosure 6.3 and the limiting side plate 6.4.

[0029] The rear corners of the limiting panel 6.2, the limiting barrier 6.3, and the limiting side plate 6.4 are all aligned with the two sides and the top corner of the rear corner of the tray 1.

[0030] A stop bar 11 is disposed on one side of the rear part above the tray 1, with its two ends connected to the left and right limiting side plates 6.4 respectively. The top surface of the stop bar 11 is flush with the top surface of the limiting side plate 6.4, and there is a gap between the top surface of the stop bar 11 and the limiting side plate 6.4 and the top edge of the side plate 2. The tray 11 also includes a partition plate 12, which rests on the top surface of the stop bar 11 and the limiting side plate 6.4. The gap space on the partition plate 12 is used to prevent cable equipment.

[0031] The two first limiting seats 6, the stop bar 11 and the tray 1 together form a support frame structure for the four side plates 2.

[0032] Preferably, the limiting support card 6.1 and the butterfly buckle are symmetrically arranged on the inner and outer sides of the side plate 2 to form a clamping effect on the side plate 2, further strengthening the structural strength of the butterfly buckle at the connection between the side plate 2 and the tray 1.

[0033] A second limiting seat 7 is provided on the front side of the tray 1, and a third limiting seat 8 is provided on the rear side. The outer side of the second limiting seat 7 is aligned with the front side of the tray 1, and the outer side of the third limiting seat 8 is aligned with the rear side of the tray 1.

[0034] The second limiting seat 7 consists of multiple front support blocks 7.1 located at the bottom, a front panel 7.2 mounted above the front support blocks 7.1, and front transverse ribs 7.3 disposed on the front panel 7.2. The third limiting seat 8 consists of multiple rear support blocks 8.1 located at the bottom, a rear panel 8.2 mounted above the rear support blocks 8.1, and rear transverse ribs 8.3 disposed on the rear panel 8.2. The second limiting seat 7 and the third limiting seat 8 have a stepped structure, wherein the front transverse ribs 7.3 of the second limiting seat 7 have the same width as the front panel 7.2, while the width of the rear transverse ribs 8.2 of the third limiting seat 8 is smaller than that of the rear panel 8.2.

[0035] The first limiting seat 6, the second limiting seat 7, and the third limiting seat 8 provide lateral support reinforcement at the connection between the side plate 2 and the tray 1. The limiting enclosure 6.3 and the limiting side plate 6.4 provide structural reinforcement against impact deformation for the lateral surface of the side plate 2. The vertical protrusions on both sides of the concave structure of the fiber enclosure 6.3 and the limiting side plate 6.4 provide vertical support reinforcement at the connection between the side plates 2. The stop bar 11 provides horizontal support reinforcement between the opposing first limiting seats 6. Furthermore, buffer pads 9 are provided on the first limiting seat 6, the second limiting seat 7, and the third limiting seat 8. The peripheral edge of the electronic circuit board testing instrument is secured within the supporting frame structure, achieving limiting of the testing instrument during transportation. The elastic cushioning capacity of the packaging box for the testing instrument can be adjusted by adjusting the thickness of the buffer pads 9. Moreover, due to the combined effect of the reinforced base and the reinforced frame structure, the impact deformation resistance of the packaging box is greatly enhanced, effectively preventing impact damage to the testing instrument.

[0036] Furthermore, a reinforcing frame 10 can be provided on the outer edge of the side plate 2. The reinforcing frame 10 is located between the side plate 2 and the butterfly buckle, and its position corresponds to the limiting support block 6.1, the front support block 7.1 and the rear support block 8.1 of the inner side limit of the side plate 2, forming reinforcement on both the inner and outer sides.

[0037] The top cover of tray 1 may also be provided with several limiting blocks in the middle to further limit and fix the testing instrument, and a buffer pad is laid between the limiting blocks and the testing instrument for buffering.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and novel concept of this utility model, should be included within the protection scope of this utility model.
