Description

Technical Field

[0001] The utility model relates to the field of PE tarpaulins, in particular to a stretch-resistant PE tarpaulin. Background Art

[0002] Tarpaulin (also known as waterproof cloth) is a waterproof material with high strength, good toughness and flexibility. PE tarpaulin is generally produced using HDPE (high-density polyethylene), which has a high operating temperature and good hardness, mechanical strength and chemical resistance.

[0003] PE tarpaulin is sun-resistant, frost-resistant, aging-resistant, corrosion-resistant, lightweight, easy to fold and durable. It is cheaper than PVC tarpaulin. However, due to the limitation of process materials, PE tarpaulin is not as durable as PVC. When the stress point of the tarpaulin is inclined to the texture of the base layer of the tarpaulin, the PE tarpaulin is very easy to stretch and tear. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a stretch-resistant PE tarpaulin which can effectively improve the tensile strength of the base fabric layer in response to the current status of the existing technology.

[0005] The utility model is achieved through the following technical solution: the utility model proposes a stretch-resistant PE tarpaulin, including a base fabric layer, a connecting edge is installed on the outer side of the base fabric layer, a square-shaped elastic edge is installed inside the connecting edge, elastic connecting strips are installed at equal intervals between the elastic edges, an anti-deformation stretch layer 1 is installed on the upper and lower sides of the base fabric layer, an anti-deformation stretch layer 2 is installed on the outer side of the anti-deformation stretch layer 1, and a PVC waterproof membrane is also installed on the outer side of the anti-deformation stretch layer 2.

[0006] By adopting the above technical solution, the elastic connecting strip cooperates with the connecting edge to achieve a preliminary improvement in the tensile performance of the PE tarpaulin, and the anti-deformation tensile layer 1 cooperates with the anti-deformation tensile layer 2 to further improve the tensile performance of the PED tarpaulin, thereby enabling the PE tarpaulin to have three types of tensile performance when in use.

[0007] Furthermore, the connecting edge is formed on the base fabric layer, and both the connecting edge and the base fabric layer are woven from PE flat yarn.

[0008] By adopting the above technical solution, it can be ensured that the base fabric layer has the characteristics of sun resistance, frost resistance, aging resistance, corrosion resistance, lightness, foldability and durability, while ensuring the basic strength of the PE tarpaulin.

[0009] Furthermore, the elastic edge and the elastic connecting strip are both made of elastic rubber material, and the elastic connecting strip is bonded to the elastic material.

[0010] By adopting the above technical solution, the elastic edges and the elastic connecting strips are both thin sheet structures, which makes the PE tarpaulin more tensile-resistant during use without increasing the overall weight of the PE tarpaulin too much.

[0011] Furthermore, the first anti-deformation stretch layer is connected to the base fabric layer by sewing, and the second anti-deformation stretch layer is connected to the base fabric layer by sewing.

[0012] By adopting the above technical solution, the first anti-deformation stretch layer and the reliable installation of the anti-deformation stretch layer on the base fabric layer can be ensured.

[0013] Furthermore, the first anti-deformation stretch layer is woven from aramid fiber filaments, and the second anti-deformation stretch layer is woven from polyester fiber filaments.

[0014] By adopting the above technical solution, the tensile strength of the first anti-deformation tensile layer and the second anti-deformation tensile layer can be effectively ensured.

[0015] Furthermore, Velcro 1 is evenly distributed on the PVC waterproof membrane located on the lower side of the base fabric layer, and Velcro 2 is installed on one side of Velcro 1.

[0016] By adopting the above technical solution, the first hook and loop fastener cooperates with the second hook and loop fastener to fix the middle part of the PE tarpaulin on the vehicle frame or the covered cargo, so as to ensure that the PE tarpaulin fits more closely with the stacked cargo during use, and avoid the disadvantage that the PE tarpaulin is blown away by external wind during use due to local loosening of the straps during use.

[0017] Furthermore, the first hook and loop fastener and the second hook and loop fastener are both sewn and connected to the base fabric layer, and the first hook and loop fastener is longer than the second hook and loop fastener.

[0018] By adopting the above technical solution, when fixing the middle part of the PE tarpaulin, the first hook and loop fastener is passed around the goods and then adhered to the second hook and loop fastener.

[0019] Furthermore, the connecting edges are evenly distributed with tensile connectors, which include a bottom sleeve and a top sleeve installed on the upper side of the bottom sleeve through a screw base, and the tensile connector also includes ring bases installed on the top sleeve and the bottom sleeve respectively.

[0020] By adopting the above technical solution, the tensile connector runs through the connecting edge, and the tensile connector is mainly connected to the external binding strap to achieve reliable fixation of the PE tarpaulin.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The utility model installs square frame-shaped elastic edges around the base fabric layer, and evenly distributes elastic connecting strips that pass through the middle of the base fabric layer between the elastic edges. At the same time, it cooperates with the design of the anti-deformation stretch layer 1 and the anti-deformation stretch layer 2, so that the PE tarpaulin has three tensile properties when in use, effectively avoiding the disadvantage of the PED tarpaulin being torn and damaged when covering stacked goods, and thus prolonging the service life of the PE tarpaulin.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] like Figure 1-Figure 3As shown, a stretch-resistant PE tarpaulin in this embodiment includes a base fabric layer 4, a connecting edge 2 is installed on the outside of the base fabric layer 4, a square elastic edge 9 is installed inside the connecting edge 2, and elastic connecting strips 7 are installed at equal intervals between the elastic edges 9. Anti-deformation stretch layer 1 6 is installed on the upper and lower sides of the base fabric layer 4, and anti-deformation stretch layer 2 5 is installed on the outside of the anti-deformation stretch layer 1 6. A PVC waterproof membrane 3 is also installed on the outside of the anti-deformation stretch layer 2 5. The PVC material itself has good waterproof performance. Therefore, under the action of the PVC waterproof membrane 3, the overall waterproof performance of the PE tarpaulin is improved. The elastic connecting strip 7 cooperates with the connecting edge 2 to achieve a preliminary improvement in the tensile performance of the PE tarpaulin. The anti-deformation stretch layer 1 6 cooperates with the anti-deformation stretch layer 2 5 to further improve the tensile performance of the PED tarpaulin, so that the PE tarpaulin has three tensile properties when in use.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, the connecting edge 2 is formed on the base fabric layer 4, and the connecting edge 2 and the base fabric layer 4 are both woven with PE flat wire, which can ensure that the base fabric layer 4 has the characteristics of sun resistance, frost resistance, aging resistance, corrosion resistance, lightness, easy folding, and durability, while ensuring the basic strength of the PE tarpaulin. The elastic edge 9 and the elastic connecting strip 7 are both made of elastic rubber, and the elastic connecting strip 7 is elastically bonded. The elastic edge 9 and the elastic connecting strip 7 are both thin sheet structures, which make the PE tarpaulin more tensile-resistant when in use without increasing the overall weight of the PE tarpaulin too much.

[0033] like Figure 1-Figure 3 As shown, in this embodiment, the anti-deformation tensile layer 1 6 is sewn and connected to the base fabric layer 4, and the anti-deformation tensile layer 2 5 is sewn and connected to the base fabric layer 4, which can ensure the reliable installation of the anti-deformation tensile layer 1 6 and the anti-deformation tensile layer 2 5 on the base fabric layer 4. The anti-deformation tensile layer 1 6 is woven from aramid fiber yarns, and the anti-deformation tensile layer 2 5 is woven from polyester fiber yarns. The aramid fiber yarns used in the anti-deformation tensile layer 1 6 are specifically Kevlar aramid fiber yarns. Kevlar aramid fiber yarns are a super fiber with a tensile strength of 5 times that of steel wire and 10 times that of aluminum at the same quality. With its excellent heat resistance and cut resistance, it is widely used in tensile fabrics. The polyester fiber yarn itself has good elasticity and tensile properties, so that the anti-deformation tensile layer 2 5 itself has good elasticity and tensile properties, so that the tensile properties of the PE tarpaulin are doubly enhanced under the action of the anti-deformation tensile layer 1 6 and the anti-deformation tensile layer 2 5.

[0034] like Figure 4As shown, in this embodiment, the PVC waterproof membrane 3 located on the lower side of the base fabric layer 4 is evenly covered with Velcro 10, and Velcro 2 11 is installed on one side of Velcro 10. Velcro 10 and Velcro 2 11 cooperate to fix the middle part of the PE tarpaulin to the frame or the covered cargo, so as to ensure that the PE tarpaulin fits more closely with the stacked cargo when in use, and avoids the disadvantage of the PE tarpaulin being blown away by external wind force when in use due to loosening of local straps. Velcro 10 and Velcro 2 11 are both sewn and connected to the base fabric layer 4. The length of Velcro 10 is greater than that of Velcro 2 11. When fixing the middle part of the PE tarpaulin, Velcro 10 is passed around the cargo and then adhered to Velcro 2 11.

[0035] like Figure 1 、 Figure 4 and Figure 5 As shown, in this embodiment, the connecting edge 2 is also evenly distributed with a tensile connector 1, the tensile connector 1 includes a bottom sleeve 103 and a top sleeve 101 installed on the upper side of the bottom sleeve 103 through a screw platform 8, the tensile connector 1 also includes a ring platform 102 installed on the top sleeve 101 and the bottom sleeve 103 respectively, the tensile connector 1 runs through the connecting edge 2, and the tensile connector 1 is mainly connected to the external strap to achieve reliable fixation of the PE tarpaulin. The tensile connector 1 is pre-opened on the connecting edge 2 when in use. The top sleeve 101 and the bottom sleeve 103 are screwed together by the screw platform 8. In the process of screwing the bottom sleeve 103 and the top sleeve 101, the ring platform 102 is pressed into the groove reserved on the connecting edge 2, so that when the top sleeve 101 and the bottom sleeve 103 are connected with the external pulling strap, the contact area between the tensile connector 1 and the connecting edge 2 is increased, so that the pulling force on the connecting edge 2 at the tensile connector 1 is dispersed, avoiding rupture and damage on the connecting edge 2 at the tensile connector 1.

[0036] The specific implementation process of this embodiment is as follows: when it is necessary to cover and protect the stacked goods, first fit the back of the tarpaulin to the goods, then pass the external straps through the tensile connectors 1, and connect the straps to the external fixing rods, so that the PE tarpaulin can be put into use. During use, by installing square elastic edges 9 around the base fabric layer 4, and evenly distributing elastic connecting strips 7 that pass through the middle of the base fabric layer 4 between the elastic edges 9, and coordinating the design of the anti-deformation tensile layer 1 6 and the anti-deformation tensile layer 2 5, the PE tarpaulin has three tensile properties when in use, effectively avoiding the disadvantage of the PED tarpaulin being torn and damaged when covering the stacked goods, thereby improving the service life of the PE tarpaulin, and at the same time By adding a ring platform 102 to the tensile connector 1, the contact area between the tensile connector 1 and the connecting edge 2 is increased, so that the pulling force on the connecting edge 2 at the tensile connector 1 is dispersed, avoiding rupture and damage on the connecting edge 2 at the tensile connector 1. When the PE tarpaulin is used on a frame to perform this operation on stacked goods in the frame, in order to avoid the PE tarpaulin being blown away by external wind during use due to the loosening of the local binding straps of the PE tarpaulin, the Velcro 10 can be passed through the lower side of the goods according to actual use needs, and the Velcro 2 11 is bonded to the Velcro 10, so as to achieve the fixation of the middle part of the PE tarpaulin during use, avoiding the disadvantage of the PE tarpaulin being blown away when it is partially loose during use.

[0037] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
