[0039] Figure 12 yes Figure 11 A longitudinal sectional view. Detailed Implementation

[0040] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0041] Reference Figures 1-12 A plastic sheet connection structure includes a first plastic sheet 1 and a second plastic sheet 2, wherein the first plastic sheet 1 and the second plastic sheet 2 are separately arranged. The first plastic sheet 1 and the second plastic sheet 2 are separately arranged, meaning that the first plastic sheet 1 and the second plastic sheet 2 are two separate sheets, and whether they are connected is irrelevant.

[0042] The first plastic sheet 1 has a first end 1-1 near the second plastic sheet 2 and a second end 1-2 away from the second plastic sheet 2. The second plastic sheet 2 has a first end 2-1 away from the first plastic sheet 1 and a second end 2-2 near the first plastic sheet 1. The first end 1-1 of the first plastic sheet and the second end 2-2 of the second plastic sheet are opposite each other. Preferably, the first end 1-1 of the first plastic sheet and the second end 2-2 of the second plastic sheet are directly opposite each other. Of course, it is also possible that the first end 1-1 of the first plastic sheet and the second end 2-2 of the second plastic sheet are staggered.

[0043] The plastic sheet connection structure also includes a connector 3 disposed on the back of the first plastic sheet 1 and the back of the second plastic sheet 2. The connector 3 is detachably connected to the back of the first plastic sheet 1 and the back of the second plastic sheet 2. The connector 3 spans the first end 1-1 of the first plastic sheet and the second end 2-2 of the second plastic sheet, thereby connecting the first plastic sheet 1 and the second plastic sheet 2 into a flat sheet. A preferred arrangement of the connector is that both the back of the first plastic sheet 1 and the back of the second plastic sheet 2 have positioning grooves 4, and the connector 3 is located in the positioning grooves 4. During assembly, the connector 3 is first placed into the positioning grooves 4 to initially position the connector 3, and then the next detachable connection is performed.

[0044] A preferred arrangement of the connector 3 is that the connector 3 is vertically arranged on the back of the first plastic plate 1 and the back of the second plastic plate 2. The vertically arranged connector 3 can better and more stably fix the oppositely arranged first plastic plate 1 and second plastic plate 2, especially when the first end 1-1 of the first plastic plate and the second end 2-2 of the second plastic plate are directly opposite each other.

[0045] The connector 3 is preferably attached at least to the first end 1-1 of the first plastic plate and the second end 2-2 of the second plastic plate to achieve a better connection. Of course, the best way is for the connector 3 to be completely attached to the back of the first plastic plate 1 and the back of the second plastic plate 2, so that the connection between the first plastic plate 1 and the second plastic plate 2 is more stable.

[0046] After the connector 3 is detached, the first plastic plate 1 can be stacked with the second plastic plate 2, thereby completing the folding and reducing the packaging volume. The first plastic plate 1 and the second plastic plate 2 can be stacked in the following ways: the back of the first plastic plate 1 is stacked with the back of the second plastic plate 2, the front of the first plastic plate 1 is stacked with the front of the second plastic plate 2, the back of the first plastic plate 1 is stacked with the front of the second plastic plate 2, or the front of the first plastic plate 1 is stacked with the back of the second plastic plate 2. The figure shows the case where the back of the first plastic plate 1 is stacked with the back of the second plastic plate 2.

[0047] A preferred approach is that the outer contour of the first plastic plate 1 is basically the same as that of the second plastic plate 2. In this way, when the first plastic plate 1 and the second plastic plate 2 are stacked, the first plastic plate 1 and the second plastic plate 2 basically completely overlap, the first plastic plate 1 will not extend beyond the second plastic plate 2, and the second plastic plate 2 will not extend beyond the first plastic plate 1, which can further reduce the packaging volume after the first plastic plate 1 and the second plastic plate 2 are folded.

[0048] Since the first plastic plate 1 and the second plastic plate 2 are connected into a single flat board by the connector 3, the separate arrangement of the first plastic plate 1 and the second plastic plate 2 as mentioned above means that the first plastic plate 1 and the second plastic plate 2 are two separate boards, and whether they are connected is irrelevant. The first end 1-1 of the first plastic plate and the second end 2-2 of the second plastic plate do not need to be connected; they can simply touch each other. Alternatively, the first end 1-1 of the first plastic plate and the second end 2-2 of the second plastic plate can be hinged to each other without affecting the folding of the first plastic plate 1 and the second plastic plate 2. Specifically, a hinge 5 can be used to hinge the first end 1-1 of the first plastic plate to the second end 2-2 of the second plastic plate.

[0049] To achieve a basically stable connection and fixation effect, generally speaking, the extension length of the connector 3 from the first end 1-1 of the first plastic plate to the second end 1-2 of the first plastic plate is at least 1 / 4 of the length from the first end 1-1 to the second end 1-2 of the first plastic plate; the extension length of the connector 3 from the second end 2-2 of the second plastic plate to the first end 2-1 of the second plastic plate is at least 1 / 4 of the length from the second end 2-2 to the first end 2-1 of the second plastic plate.

[0050] In one embodiment, the connector 3 extends from the first end 1-1 of the first plastic plate to the second end 1-2 near the first plastic plate. The end of the connector 3 near the second end 1-2 of the first plastic plate is provided with a connecting cavity. This method allows the connector 3 to be connected to other components using the connecting cavity at its end.

[0051] As a preferred embodiment, the connector 3 is preferably a connecting rod, ideally a metal rod for better strength. The connecting rod is connected to the first plastic plate 1 and the connecting rod is connected to the second plastic plate 2 by detachable fasteners; disassembling the connecting rod simply requires removing the fasteners.

[0052] In one embodiment, the fastener is a plurality of snap-fit ​​fasteners, which are fastened to the connecting rod and snap-fit ​​connected to the first plastic plate 1 and the second plastic plate 2. Specifically, the snap-fit ​​connection structure may be as follows: The back of both the first plastic plate 1 and the back of the second plastic plate 2 are provided with slots 6; baffles 7 are provided on both sides of the slots 6; a sandwich layer 8 is formed between the baffles 7 and the bottom surface of the slots 6; the snap-fit ​​fastener is a clip 18 with an opening, and the connecting rod is clamped in the clip 18; locking wings 9 are provided on both outer sides of the clip 18, and the locking wings 9 slide into the sandwich layer 8, thereby locking the connecting rod to the first plastic plate 1 and the second plastic plate 2.

[0053] A preferred embodiment is as follows: the connecting rod has a rectangular cross-section; the clamp 18 includes a first side clamp 19, a second side clamp 20, and a base plate 21 connecting the first side clamp 19 and the second side clamp 20; the connecting rod is clamped in the clamping opening formed by the first side clamp 19, the second side clamp 20, and the base plate 21; the locking wings 9 are respectively disposed on the outer side of the first side clamp 19 and the outer side of the second side clamp 20. This type of clamp structure can better adapt to the rectangular cross-section of the connecting rod and can better lock the connecting rod onto the first plastic plate 1 and the second plastic plate 2.

[0054] In one embodiment, the back side or back surface of the first plastic sheet 1 is provided with a first protrusion 10 and a first recess 11, and the back side or back surface of the second plastic sheet 2 is provided with a second protrusion 12 adapted to the first recess 11 and a second recess 13 adapted to the first protrusion 10. The first protrusion 10 on the first plastic sheet 1 and the second protrusion 12 on the second plastic sheet 2 can provide a reinforcing effect, increasing the strength of the plastic sheet, especially for blow-molded plastic sheets.

[0055] After the first plastic plate 1 and the second plastic plate 2 are stacked to complete the folding, the first protrusion 10 is inserted into the second concave portion 13, and the second protrusion 12 is inserted into the first concave portion 11. In this way, when the back of the first plastic plate 1 and the back of the second plastic plate 2 are in contact to complete the folding, the influence of the presence of the first protrusion 10 and the second protrusion 12 on the increased thickness after folding can be reduced.

[0056] The first plastic plate 1 and the second plastic plate 2 are stacked in such a way that when the back of the first plastic plate 1 and the back of the second plastic plate 2 are stacked, the first protrusion 10 and the first concave portion 11 are provided on the back of the first plastic plate 1, and the second protrusion 12 and the second concave portion 13 are provided on the back of the second plastic plate 2.

[0057] The first plastic plate 1 and the second plastic plate 2 are stacked in such a way that when the front side of the first plastic plate 1 is stacked with the front side of the second plastic plate 2, the first protrusion 10 and the first concave part 11 are provided on the front side of the first plastic plate 1, and the second protrusion 12 and the second concave part 13 are provided on the front side of the second plastic plate 2.

[0058] The first plastic plate 1 and the second plastic plate 2 are stacked in such a way that when the back of the first plastic plate 1 is stacked with the front of the second plastic plate 2, the first protrusion 10 and the first concave portion 11 are provided on the back of the first plastic plate 1, and the second protrusion 12 and the second concave portion 13 are provided on the front of the second plastic plate 2.

[0059] The first plastic plate 1 and the second plastic plate 2 are stacked in such a way that when the front side of the first plastic plate 1 is stacked with the back side of the second plastic plate 2, the first protrusion 10 and the first concave part 11 are provided on the front side of the first plastic plate 1, and the second protrusion 12 and the second concave part 13 are provided on the back side of the second plastic plate 2.

[0060] A better approach is that after the first plastic plate 1 and the second plastic plate 2 are stacked together to complete the folding, the first protrusion 10 is completely embedded in the second recess 13 and the second protrusion 12 is completely embedded in the first recess 11, so that the first plastic plate 1 can be tightly attached to the second plastic plate 2, thereby further reducing the volume after folding.

[0061] In a preferred embodiment, the first protrusion 10 and the second protrusion 12 that can play a reinforcing role are strip-shaped ribs, and the corresponding first concave portion 11 and the second concave portion 13 are strip-shaped grooves, with the reinforcing effect of the strip-shaped ribs being more obvious.

[0062] A preferred method is that, when folded, the back of the first plastic plate 1 overlaps with the back of the second plastic plate 2. The first protrusion 10 and the first recess 11 are located on the back of the first plastic plate 1, and the second protrusion 12 and the second recess 13 are located on the back of the second plastic plate 2. The connector 3 has a positioning opening 14, and a portion of the first protrusion and / or the second protrusion is embedded in the positioning opening 14. In this case, this portion of the first protrusion and / or the second protrusion serves as a positioning protrusion 15. During assembly, the positioning protrusion 15 is embedded in the positioning opening 14 to initially position the connector 3 before proceeding to the next step of detachable connection. This initial positioning method, along with the initial positioning method of the positioning groove mentioned earlier, can exist independently or simultaneously.

[0063] In one embodiment, the first end 1-1 of the first plastic plate has a first tongue 16 extending toward the second plastic plate 2, and the second end 2-2 of the second plastic plate has a second tongue 17 extending toward the first plastic plate 1. The first tongue 16 and the second tongue 17 are stacked one on top of the other. The end of the first tongue 16 is close to the second end 2-2 of the second plastic plate, and the end of the second tongue 17 is close to the first end 1-1 of the first plastic plate. This forms a bend that facilitates waterproofing between the end of the first tongue 16 and the second end 2-2 of the second plastic plate, between the first tongue 16 and the second tongue 17, and between the end of the second tongue 17 and the first end 1-1 of the first plastic plate. By forming this bend, if the environment is wet or rainy, water flows or seeps along the bend. The long path of flow or seepage causes the water to lose kinetic energy and flow downwards under the action of gravity, thus achieving a better waterproofing effect.
