In this embodiment, the second support plate 10223 can be selectively clamped to the position-limiting clamping strip 1013, that is, the second support plate 10223 can be clamped to different positions of the position-limiting clamping strip 1013, so as to adjust the height of the buffer structure 102. Each limit clamping strip 1013 is provided with two sets of limit clamping grooves 10131 which are symmetrical about the center of the limit clamping strip 1013, an included angle formed by the central line of the notch of each set of limit clamping grooves 10131 and the horizontal line of the fixing plate 1021 gradually increases or decreases along a direction, and the second supporting plate 10223 is clamped into the limit clamping grooves 10131. The angle range of the included angle is greater than or equal to 0 degree and less than or equal to 90 degrees, so that when the second supporting plate 10223 is clamped into different limiting clamping grooves 10131, the heights of the buffer structures 102 have different heights, and the box cover 1 also has different heights. It should be noted that, in the actual work, can set up spacing draw-in groove 10131's inclination according to the thickness of goods to make the goods in the in-process of follow-up packing, can directly select spacing draw-in groove 10131 according to the quantity of goods, in order to improve packing efficiency, practice thrift the cost of labor, be fit for high yield, easy operation, low cost.
In the embodiment, as shown in fig. 3, the included angle between the center line of each set of the limiting slots and the fixing plate 1021 is gradually increased from the center of the limiting strip 1013 to the two ends thereof. Of course, in other embodiments, the included angle between the central line of the slot of each set of the position-limiting slots and the fixing plate 1021 decreases gradually from the center of the position-limiting clamping strip 1013 to the two ends thereof.
In this embodiment, the width of the notch of the position-limiting clamping groove 10131 is the same as the thickness of the buffer structure 102, and at least 1/4-1/2 of the width of the second support plate 10223 can be clamped into the position-limiting clamping groove 10131, so that the second support plate 10223 can be firmly clamped into the position-limiting clamping groove 10131, and the buffer structure 102 can be prevented from rebounding after being clamped.
A plurality of joint interfaces may be seted up to current case lid on the fixed plate, and buffer structure is folding, and this buffer structure's rear end bearing structure is fixed in this joint interface, because the fixed plate is fixed connection to case lid body, and the lower surface of case lid body is tangent with the upper surface of fixed plate promptly to and the degree of depth of this joint interface is the fixed plate thickness exactly. Consequently, after current buffer structure's rear end bearing structure was fixed at this joint interface, rear end bearing structure can be contradicted by the fixed plate and is rebounded out and can't realize fixed effect, still can influence the planarization between fixed plate and the case lid, the use of inconvenient case lid.
The buffering structure 102 provided by the embodiment can overcome the above problems, by cutting out a plurality of turnover limiting clamping strips 1013 at the middle part of the fixing plate 1021, and providing two sets of centrosymmetric limiting clamping grooves 10131 on each limiting clamping strip 1013, the second supporting plate 10223 is fixed in the limiting clamping grooves 10131, and will not be rebounded, and will not affect the flatness between the fixing plate 1021 and the case cover 1, and the case cover 1 is convenient and simple to use.
Further, the included angle formed by the central line of each set of limiting clamping grooves 10131 and the horizontal line of the fixing plate 1021 gradually increases from the center of the limiting clamping strip 1013 to the two ends thereof, so that when the second supporting plate 10223 is clamped from the center of the limiting clamping strip 1013 to the limiting clamping grooves 10131 at the two ends thereof, the height of the buffer structure 102 gradually increases from the center of the limiting clamping strip 1013 to the two ends thereof, and thus the height of the buffer structure 102, that is, the height of the box cover 1, can be adjusted by a simple clamping manner.
As shown in fig. 4-5, the present embodiment further provides a packing box for loading goods, which includes a box body 2 and the aforementioned box cover 1, wherein the box cover 1 and the box body 2 are connected to each other in a matching manner, and an accommodating space 201 is provided in the box body 2 for loading goods. The goods are preferably fragile goods such as flat displays 3 (e.g., liquid crystal displays, OLED displays, and the like) and glasses, but may be other goods, and are not particularly limited herein.
During the use of the packing box, when goods are loaded into the box body 2, the clamping position of the second support plate 10223 of the box cover 1 and the spacing clamping strip 1013 is adjusted according to the quantity of the goods, so that no gap exists between the box cover 1 and the goods when the box cover 1 and the box body 2 are connected with each other. Specifically, set for the angle of spacing recess according to display 3's thickness to when injecing one or more display 3 and being loaded, second backup pad 10223 can the joint to which spacing draw-in groove 10131, with further improvement packing efficiency, practices thrift the cost of labor, is fit for high yield, easy operation, low cost.
As shown in fig. 4-6, in one embodiment, when one display 3 is loaded in the accommodating space 201 of the box 2, the height of the buffer structure 102 needs to be adjusted, that is, the left second support plate 10223 is inserted into the leftmost one of the left group of limiting recesses, and the right second support plate 10223 is inserted into the rightmost one of the right group of limiting recesses, at this time, the first support plate 10221 is disposed perpendicular to the fixing plate 1021 and the plane connecting plate 10222. Therefore, when the box cover 1 and the box body 2 are covered, the lower surface of the box cover 1 is tangent to the upper surface of the box body 2, the lower surface of the buffer structure 102 is tangent to the upper surface of the display 3, no gap exists between the display 3 and the box cover 1, the packaging is more compact, the compressive strength of the packaging box is improved, the display 3 cannot shake in the transportation process, the display 3 can be protected to the maximum extent, and the transportation risk is reduced.
As shown in fig. 7-8, in one embodiment, when seven displays 3 are loaded in the accommodating space 201 of the box 2, the height of the buffer structure 102 needs to be adjusted, that is, the left second support plate 10223 is inserted into the second left-to-right limiting groove of the left group of limiting grooves, and the right second support plate 10223 is inserted into the second left-to-right limiting groove of the right group of limiting grooves, at this time, the first support plate 10221 is disposed obliquely with the fixing plate 1021 and the plane connecting plate 10222.
