It is the best building material to replace glass and plexiglass, and has excellent properties such as light weight, weather resistance, super strength, flame retardancy, sound insulation, etc. The polycarbonate plate is usually fixed by a seal during installation.

[0003] The current polycarbonate plates have the following problems during installation: Since the essence of the polycarbonate plate is a unique engineering thermoplastic, it has the common problems of general plastics, including being greatly affected by temperature. The joints of two plates need to reserve enough expansion space according to the local temperature difference change to ensure that the plates can expand and contract freely without cracking when the temperature changes. Although the existence of the gap can prevent the plates from cracking, it also reduces the sealing performance of the plates, making its rainproof function significantly decline. Therefore, it is necessary to design a new connecting structure to improve this problem. Content of the Utility Model

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0033] Please refer to Figures 1-6 , the present utility model provides a technical solution: a connection structure for polycarbonate plates, used to seal the connection seam between at least two plate bodies 1, including:

[0034] a connecting component for fixedly connecting adjacent plate bodies 1;

[0035] a first sealing member provided at the left end of the plate body 1;

[0036] The second seal member disposed at the right end of the plate body 1, during use, through the cooperation of the first seal member of one of the plate bodies 1 and the second seal member of the other plate body 1, a sealed area is formed at the connection seam between adjacent plate bodies 1;

[0037] The third seal member for sealing the through holes 2 opened at the front and rear ends of the plate body 1;

[0038] Adopting the above technical solution ensures that there is enough expansion space at the joints between the plate bodies 1, and at the same time ensures good sealing performance at the joints. During use, adjacent plate bodies 1 are fixed through connecting components, thereby realizing the connection of adjacent plate bodies 1. At the same time, since seal members are provided at both ends of each plate body 1, during fixation, the first seal member of one of the plate bodies 1 can also be matched with the second seal member of the other plate body 1, thereby sealing the connection seam between adjacent plate bodies 1. When the temperature of the plate body 1 changes, due to the connection seam between the plate bodies 1 providing an expansion space that can expand and contract freely, the plate body 1 will not break. Due to the provision of seal members, the connection seam remains in a sealed state during the expansion and contraction process, ensuring that its sealing performance is not affected.

[0039] As Figure 2 shown, in this embodiment, the connecting component includes: a chuck 3 disposed at the left end of the plate body 1; a first card slot 4 disposed at the right end of the plate body 1 and engagingly cooperating with the chuck 3;

[0040] Adopting the above technical solution can splice two adjacent plate bodies 1. During use, the chuck 3 of one of the plate bodies 1 is inserted into the first card slot 4 of the other plate body 1, thereby splicing the two plate bodies 1.

[0041] As Figure 2 shown, in this embodiment, the first seal member is a first sealing strip 5 disposed at the left end of the plate body 1, and the second seal member is a second sealing strip 6 disposed at the right end of the plate body 1. After adjacent plate bodies 1 are spliced, the second sealing strip 6 of one of the plate bodies 1 is mutually attached to the first sealing strip 5 of the other plate body 1;

[0042] Adopting the above technical solution can seal the connection seam between the plate bodies 1. When the chuck 3 of one of the plate bodies 1 is inserted into the first card slot 4 of the other plate body 1, the second sealing strip 6 of one of the plate bodies 1 is also synchronously inserted into the first sealing strip 5 of the other plate body 1, and the second sealing strip 6 and the first sealing strip 5 are mutually attached to form a sealing effect on the connection seam.

[0043] As Figure 2As shown, in this embodiment, both the first sealing strip 5 and the second sealing strip 6 form raised portions on the side away from the plate body 1. After adjacent plate bodies 1 are spliced, the raised portions of the first sealing strip 5 and the second sealing strip 6 abut against each other;

[0044] Adopting the above technical solution can further improve the sealing effect of the second sealing strip 6 and the first sealing strip 5 on the connection seam. After the first sealing strip 5 and the second sealing strip 6 are attached to each other, the raised portion of the first sealing strip 5 will exert a squeezing effect on the second sealing strip 6, and the raised portion of the second sealing strip 6 will exert a squeezing effect on the first sealing strip 5, so that the raised portion is deformed under pressure, effectively blocking the gap between the first sealing strip 5 and the second sealing strip 6 and further improving the sealing effect.

[0045] As Figure 5 shown, in this embodiment, the connecting structure further includes: an end plate 7 provided with a second card slot 8, and the second card slot 8 is matched with the card head 3; a mounting plate 9 provided with a first bolt hole 10, one end of the mounting plate 9 is connected to the end plate 7, and the other end of the mounting plate 9 is attached to the mounting surface; the end plate 7 is provided with the first sealing strip 5 or the second sealing strip 6 on the side close to the plate body 1;

[0046] Adopting the above technical solution can fix the plate body 1 on the mounting surface. During use, align the second card slot 8 of the end plate 7 with the card head 3 and insert it, then the end plate 7 can be fixedly connected to the plate body 1, making one side of the mounting plate 9 fit the mounting surface. Insert a bolt 18 into the first bolt hole 10 on the surface of the mounting plate 9 and screw the threaded end of the bolt 18 into the mounting surface, then the plate body 1 can be fixed on the mounting surface.

[0047] As Figure 3 and Figure 4 shown, in this embodiment, the third sealing member includes: a side sealing plate 11 provided with a card strip 12, and the card strip 12 is used to generate elastic tension on the inner wall of the through hole 2 after being inserted into the through hole 2 to prevent the card strip 12 from detaching from the through hole 2;

[0048] Adopting the above technical solution can seal the through hole 2 in the plate body 1 to prevent foreign objects from entering the through hole 2. During use, align the card strip 12 of the side sealing plate 11 with the through hole 2 and insert it until the card strip 12 is inserted to the deepest part of the through hole 2, and the side sealing plate 11 fits the through hole 2, thereby sealing the through hole 2. At the same time, the side sealing plate 11 can also prevent the end plate 7 and the plate body 1 from sliding relative to each other, improving the stability of the fixing structure.

[0049] As Figure 3 and Figure 4 shown, in this embodiment, the card strip 12 is provided with a plurality of convex strips 13 on the side that fits the inner wall of the through hole 2, and the convex strips 13 are in snap-fit with the grooves 14 formed on the inner wall of the through hole 2;

[0050] With the above technical solution, the card strip 12 is prevented from falling off the through hole 2. After the card strip 12 is inserted into the through hole 2, the rib 13 on the surface of the card strip 12 is embedded in the groove 14 on the inner wall of the through hole 2, thereby stably fixing the card strip 12 in the through hole 2.

[0051] As Figure 4 and Figure 5 shown, in this embodiment, the connection structure further includes: an insertion block 15 provided at one end of the side sealing plate 11, and the insertion block 15 is in snap-fit with a slot 16 formed on the surface of the end plate 7; a countersunk hole is formed on the surface of the insertion block 15, and a bolt 18 is arranged in the countersunk hole, and the threaded end of the bolt 18 is in threaded fit with a second bolt hole 17 formed in the slot 16;

[0052] With the above technical solution, the connection stability between the side sealing plate 11 and the plate body 1 is further improved. After the card strip 12 is inserted into the through hole 2, the insertion block 15 is inserted into the slot 16, and the bolt 18 is used to pass through the countersunk hole on the surface of the insertion block 15 and is in threaded connection with the second bolt hole 17 on the surface of the end plate 7, so that the side sealing plate 11 and the plate body 1 can be stably fixed.

[0053] Working principle: When in use, first insert the card head 3 of one of the plate bodies 1 into the first card slot 4 of the other plate body 1, thereby splicing the two plate bodies 1. At the same time, the second sealing strip 6 of one of the plate bodies 1 is also synchronously inserted into the first sealing strip 5 of the other plate body 1. The second sealing strip 6 and the first sealing strip 5 are mutually attached to form a sealing effect on the connection seam. And when the first sealing strip 5 and the second sealing strip 6 are mutually attached, the raised part of the first sealing strip 5 will exert a squeezing effect on the second sealing strip 6, and the raised part of the second sealing strip 6 will exert a squeezing effect on the first sealing strip 5, so that the raised part is deformed under pressure, effectively blocking the gap between the first sealing strip 5 and the second sealing strip 6 and further improving the sealing effect;

[0054] Align the second card slot 8 of the end plate 7 with the card head 3 and insert it, then the end plate 7 can be fixedly connected to the plate body 1. Align the card strip 12 of the side sealing plate 11 with the through hole 2 and insert it until the card strip 12 is inserted to the deepest part of the through hole 2, and the side sealing plate 11 fits with the through hole 2, thereby sealing the through hole 2. After the card strip 12 is inserted into the through hole 2, the insertion block 15 is inserted into the slot 16, and the bolt 18 is used to pass through the countersunk hole on the surface of the insertion block 15 and is in threaded connection with the second bolt hole 17 on the surface of the end plate 7, so that the side sealing plate 11 and the plate body 1 can be stably fixed. At the same time, the side sealing plate 11 can also prevent the end plate 7 and the plate body 1 from sliding relative to each other;

[0055] Finally, make one side of the mounting plate 9 fit with the mounting surface. Insert the bolt 18 into the first bolt hole 10 on the surface of the mounting plate 9, and screw the threaded end of the bolt 18 into the mounting surface, then the plate body 1 can be fixed on the mounting surface. When the temperature of the plate body 1 changes, since the connection seams between the plate bodies 1 provide a telescopic space that can freely expand and contract, the plate body 1 will not crack. Due to the provision of the first sealing strip 5 and the second sealing strip 6, the connection seams remain sealed during the telescopic change process, ensuring that its sealing performance is not affected.

[0056] Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
