Description

Technical Field

[0001] This utility model relates to the technical field of impact-resistant polyethylene composite panels, and in particular to a polyethylene composite panel with impact-resistant properties. Background Technology

[0002] Polyethylene is a highly crystalline, non-polar thermoplastic resin with excellent resistance to most household and industrial chemicals. Existing polyethylene composite sheets have good chemical stability and electrical insulation properties.

[0003] A search revealed a polyethylene composite board with good impact resistance, publication number CN214821579U, published on the Chinese Patent website. Although the impact resistance of the polyethylene composite board is increased by using a polyurethane elastic board, the deformation resistance and tear resistance are increased by using a glass fiber mesh, and the structural strength of the polyethylene composite board is increased by the special structure of the upper and lower polyethylene layers, the polyurethane elastic board, glass fiber mesh, and carbon fiber board in this prior art are not easy to disassemble. When the polyurethane elastic board, glass fiber mesh, and carbon fiber board are damaged, the entire polyethylene composite board needs to be replaced, which greatly increases the cost of using the polyethylene composite board. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a polyethylene composite board with impact resistance, so as to solve the problem that the polyurethane elastic board, glass fiber mesh and carbon fiber board in the prior art are not easy to disassemble. When the polyurethane elastic board, glass fiber mesh and carbon fiber board are damaged, the entire polyethylene composite board needs to be replaced, which greatly increases the cost of using the polyethylene composite board.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a polyethylene composite board with impact resistance, comprising:

[0006] Polyethylene composite panel body;

[0007] Two connecting strips are symmetrically fixed on the front and rear ends of the polyethylene composite panel body, and a comprehensive protective plate is provided between the two connecting strips.

[0008] As a further embodiment of this utility model: each of the two connecting strips has a working groove 1 at the ends that are far apart from each other, and a working groove 2 at the ends that are close to each other;

[0009] A threaded hole is provided between the first working groove and the second working groove;

[0010] A threaded rod is threaded into the threaded hole. A cross-shaped rotating head is fixed to one end of the threaded rod, and a fixing plate that abuts against the integrated protective plate is fixed to the other end of the threaded rod.

[0011] As a further embodiment of this utility model: the polyethylene composite board body is provided with reinforcing strip one and reinforcing strip two inside.

[0012] As a further embodiment of this utility model: the first reinforcing strip and the second reinforcing strip are arranged to cross each other.

[0013] As a further embodiment of this utility model: each of the two connecting strips has a groove at one end facing each other, a slider is slidably connected in the groove, and a buffer plate is fixed between the two sliders.

[0014] As a further embodiment of this utility model: a telescopic rod is fixed to the inner wall of one side of the slide groove, and the end of the telescopic rod away from the inner wall of the slide groove is fixed to the slider;

[0015] A compression spring is provided on the outer wall of the telescopic rod. One end of the compression spring is fixed to the slider, and the other end of the compression spring is fixed to the inner wall of one side of the slide groove.

[0016] As a further embodiment of this utility model: several anti-collision trapezoidal strips are installed at both the front and rear ends of the polyethylene composite panel body.

[0017] The above technical solution is adopted:

[0018] This invention changes the installation method of the integrated protective plate. Specifically, by rotating the Phillips head with a screwdriver, the Phillips head drives the threaded rod and the fixing plate to move within the threaded hole. Once the fixing plate abuts against the integrated protective plate, the integrated protective plate can be clamped and fixed. Similarly, when disassembling the integrated protective plate, simply rotate the Phillips head with a screwdriver, and the Phillips head drives the threaded rod and the fixing plate to move in the opposite direction within the threaded hole. Once the fixing plate abuts against the integrated protective plate, the integrated protective plate can be disassembled. Compared with existing methods, this invention facilitates the disassembly of the integrated protective plate. When the integrated protective plate is damaged, it is not necessary to replace the entire polyethylene composite panel body, reducing the usage cost of the polyethylene composite panel body and being more energy-efficient and environmentally friendly.

[0019] This utility model uses a comprehensive protective plate and a buffer plate to protect the polyethylene composite panel body, thereby improving the service life and structural strength of the polyethylene composite panel body. When the comprehensive protective plate is damaged or broken by impact, the buffer plate, with the cooperation of the compression spring and the telescopic rod, will buffer and weaken the impact force, further ensuring that the polyethylene composite panel body is not damaged, and further improving the service life of the polyethylene composite panel body.

Detailed Implementation

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Example 1

[0028] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5This utility model provides a technical solution: a polyethylene composite board with impact resistance, comprising a polyethylene composite board body 101; two connecting strips 102 are symmetrically fixed on the front and rear ends of the polyethylene composite board body 101, a comprehensive protective plate 103 is provided between the two connecting strips 102, a working groove 104 is provided at the ends of the two connecting strips 102 that are far apart from each other, and a working groove 2 105 is provided at the ends that are close to each other; a threaded hole 106 is provided through the working groove 104 and the working groove 2 105; a threaded rod 107 is threadedly connected in the threaded hole 106, a cross rotating head 109 is fixed at one end of the threaded rod 107, and a fixing plate 108 that abuts against the comprehensive protective plate 103 is fixed at the other end of the threaded rod 107; a reinforcing strip 110 and a reinforcing strip 2 111 are provided inside the polyethylene composite board body 101, and the reinforcing strip 110 and the reinforcing strip 2 111 are arranged to cross each other.

[0029] In this embodiment, by providing reinforcing strip 110 and reinforcing strip 211, the structural strength of the polyethylene composite panel body 101 can be improved through the joint cooperation of reinforcing strip 110 and reinforcing strip 211, thereby further improving the compressive strength and service life of the polyethylene composite panel body 101.

[0030] Specifically, this utility model changes the installation method of the integrated protective plate 103. Specifically, by rotating the Phillips head 109 with a screwdriver, the Phillips head 109 drives the threaded rod 107 and the fixing plate 108 to move within the threaded hole 106. Once the fixing plate 108 abuts against the integrated protective plate 103, the integrated protective plate 103 can be clamped and fixed. Similarly, when disassembling the integrated protective plate 103, simply rotate the Phillips head 109 with a screwdriver. The Phillips head 109 drives the threaded rod 107 and the fixing plate 108 to move in the opposite direction within the threaded hole 106. Once the fixing plate 108 is no longer abutting against the integrated protective plate 103, the integrated protective plate 103 can be disassembled. Compared to existing methods, this utility model facilitates the disassembly of the integrated protective plate 103. When the integrated protective plate 103 is damaged, it is not necessary to replace the entire polyethylene composite plate body 101, reducing the usage cost of the polyethylene composite plate body 101 and making it more energy-efficient and environmentally friendly.

[0031] Example 2

[0032] Please see Figures 1-3This utility model provides a technical solution: a polyethylene composite board with impact resistance, wherein each of the two connecting strips 102 has a groove 112 at one end facing each other, a slider 113 is slidably connected in the groove 112, a buffer plate 114 is fixed between the two sliders 113, a telescopic rod 115 is fixed on the inner wall of one side of the groove 112, and one end of the telescopic rod 115 away from the inner wall of the groove 112 is fixed to the slider 113; a compression spring 116 is provided on the outer wall of the telescopic rod 115, one end of the compression spring 116 is fixed to the slider 113, and the other end of the compression spring 116 is fixed to the inner wall of one side of the groove 112; and several anti-collision trapezoidal strips 117 are installed at the front and rear ends of the polyethylene composite board body 101.

[0033] In this embodiment, by providing anti-collision trapezoidal strips 117, the anti-collision trapezoidal strips 117 can prevent the buffer plate 114 from directly contacting the polyethylene composite plate body 101 due to excessive force, thereby preventing damage to the polyethylene composite plate body 101.

[0034] Specifically, this utility model uses a comprehensive protective plate 103 and a buffer plate 114 to protect the polyethylene composite panel body 101, thereby improving the service life and structural strength of the polyethylene composite panel body 101. When the comprehensive protective plate 103 is damaged or broken by impact, the buffer plate 114, in conjunction with the compression spring 116 and the telescopic rod 115, will buffer and weaken the impact force, further ensuring that the polyethylene composite panel body 101 is not damaged, and further improving the service life of the polyethylene composite panel body 101.

[0035] Working principle:

[0036] First, by changing the installation method of the integrated protection plate 103, specifically, by turning the cross-head rotating head 109 with a screwdriver, the cross-head rotating head 109 drives the threaded rod 107 and the fixing plate 108 to move in the threaded hole 106. After the fixing plate 108 abuts against the integrated protection plate 103, the integrated protection plate 103 can be clamped and fixed.

[0037] Secondly, when disassembling the integrated protective plate 103, simply turn the cross-head 109 with a screwdriver. The cross-head 109 will drive the threaded rod 107 and the fixing plate 108 to move in opposite directions within the threaded hole 106. Once the fixing plate 108 is no longer in contact with the integrated protective plate 103, the integrated protective plate 103 can be disassembled.

[0038] Finally, the integrated protective plate 103 and the buffer plate 114 protect the polyethylene composite panel body 101, improving its service life and structural strength. When the integrated protective plate 103 is damaged or broken by impact, the buffer plate 114, in conjunction with the compression spring 116 and the telescopic rod 115, will buffer and weaken the impact force, further ensuring that the polyethylene composite panel body 101 is not damaged, and further improving its service life.

[0039] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
