Technical Field

[0001] The utility model belongs to the technical field related to polyethylene plates, and particularly relates to a high-strength and tough hybrid-lined polyethylene plate. Background Art

[0002] The current situation and challenges of polyethylene plate technology are that, although it is widely used in fields such as construction, chemical industry, packaging, machinery, and electronics due to its good chemical resistance, electrical insulation, impact resistance, and processability, traditional polyethylene plates have limitations in strength, toughness, and environmental stress cracking resistance. Especially in applications that require high-strength and high-toughness connections, their performance often cannot fully meet the requirements.

[0003] In terms of plate connection technology, traditional fixing methods such as screws, rivets, and welding face problems such as insufficient strength at the connection points, easy corrosion, complex operation, and high costs. Especially in applications with frequent disassembly and assembly or in harsh environments, connection stability and reliability have become problems that need to be solved urgently.

[0004] However, with the increasing demand for modular design in industries such as construction, chemical industry, and packaging, innovation in plate connection technology has become crucial. An ideal connection technology should have characteristics such as simple operation, firm connection, good sealing performance, and low cost to meet the needs of rapid assembly and disassembly and ensure long-term structural stability and safety.

[0005] Although there are diverse plate connection technologies in the market, most technologies have limitations in strength, toughness, operation convenience, and cost control. Especially in applications with high-strength and high-toughness connection requirements, existing technologies are difficult to balance, which limits the application of polyethylene plates in high-end fields.

[0006] In view of this, the core of the background technology of this patent lies in addressing the deficiencies of existing polyethylene plates and their connection technologies. Through innovation in materials and structures, a high-strength and tough hybrid-lined polyethylene plate and connection system are provided to meet the urgent needs of the industry for high-performance and high-efficiency plate connection solutions. Summary of the Utility Model

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention provides a high-strength and tough hybrid-lined polyethylene sheet as Figures 1-6 shown, which includes a base plate 1. Limiting card holes 2 are opened at both the upper and lower ends and the left and right ends of the base plate 1. A fixing hole 3 communicates with the rear side of each of the plurality of said limiting card holes 2 near the center of the base plate 1. A telescopic square hole 4 communicates with the front end of each of the plurality of fixing holes 3. A threaded hole 5 communicates with the front end of each of the plurality of telescopic square holes 4, and each of the plurality of threaded holes 5 penetrates upward through the outer part of the front end of the base plate 1. Connecting members 6 are inserted into each of the plurality of limiting card holes 2 and the plurality of fixing holes 3, and one end of each of the plurality of connecting members 6 away from the center of the base plate 1 is located outside the base plate 1. The base plate 1 is made of polyethylene, and a combination of a nano-calcium carbonate layer, a mesoporous silica-ESO layer, a polypropylene ternary system composite layer and a POE polypropylene layer is coated on the outer walls of the front and rear ends of the base plate 1, having high toughness. Among them, the upper and lower ends of the base plate 1 can be connected and fixed to other base plates 1 through the connecting members 6 clamped in the limiting card holes 2 and the fixing holes 3.

[0030] Preferably, a limit clamping block 7 is provided at the center of the front end of the connecting member 6, and one end of the limit clamping block 7 close to the center of the base plate 1 is clamped inside the limit clamping hole 2. Inside the front end of the connecting member 6 near the center of the base plate 1 and inside the front end away from the center of the base plate 1, locking sliding grooves 8 penetrate forward. A locking slider 9 is slidably connected inside the locking sliding grooves 8, and the front end of the locking slider 9 is arranged in an inclined surface. A pressing slider 10 is provided at the front end of the locking slider 9, and the pressing slider 10 is slidably connected inside the telescopic square hole 4 and can be completely retracted into the telescopic square hole 4. The rear end of the pressing slider 10 is arranged in an inclined surface and is in close fit with the front end of the locking slider 9, and the locking slider 9 is slidably connected to the rear end of the pressing slider 10. A straight bolt 11 is rotatably connected inside the front end of the pressing slider 10, and the straight bolt 11 is threadedly connected inside the threaded hole 5 and can be completely screwed into the threaded hole 5. During the process of connecting and fixing multiple base plates 1, the pressing slider 10 can squeeze the locking slider 9 backward through the rotation of the straight bolt 11 inside the threaded hole 5, so that the locking sliders 9 slide relative to each other inside the locking sliding grooves 8 and are in close fit with the inner wall of the rear end of the locking sliding grooves 8 and lock with each other, thereby fixing the connecting member 6 inside the limit clamping hole 2 and the fixing hole 3. And because the fitting surfaces between the locking slider 9 and the pressing slider 10 are all arranged in inclined surfaces, when the pressing slider 10 squeezes the locking slider 9 backward, the locking slider 9 will drive the connecting member 6 to slide toward the center of the base plate 1 together, so that the limit clamping block 7 and the limit clamping hole 2 lock with each other, which can not only firmly fix the connecting member 6 inside the limit clamping hole 2 and the fixing hole 3, but also make the two base plates 1 fit closely with each other, making the connection between the two base plates 1 more tight.

[0031] Preferably, a limit clamping frame 12 is provided outside the locking slider 9, and the limit clamping frame 12 is slidably connected inside the locking sliding grooves 8 and is clamped inside the locking sliding grooves 8. A spring groove 13 is opened inside the rear end of the locking sliding grooves 8, and a boosting spring 14 is arranged inside the spring groove 13, and the boosting spring 14 is located at the rear end of the locking slider 9, so that the locking slider 9 can be clamped inside the locking sliding grooves 8 through the limit clamping frame 12 to prevent the locking slider 9 from falling off inside the locking sliding grooves 8. And when the locking slider 9 is in close fit with the locking sliding grooves 8 and the pressing slider 10, the boosting spring 14 arranged at the rear end can increase the fitting force with the pressing slider 10 and can prevent looseness between the locking slider 9 and the pressing slider 10, ensuring that the connecting member 6 can be stably fixed inside the limit clamping hole 2 and the fixing hole 3, and the boosting spring 14 can be completely retracted into the spring groove 13 without interfering with the fit between the locking slider 9 and the inner wall of the rear end of the locking sliding grooves 8.
