Description

Technical Field

[0001] The utility model belongs to the technical field of knitting nets, and particularly relates to a double-layer cross elastic knitting net. Background Art

[0002] Knitting nets are widely used in the electrolysis field, which can improve the efficiency, stability and product quality of the electrolysis process, and are an important electrolysis material and structure. The air permeability of the knitting net can ensure the passage of reaction products and the separation of reaction products. Moreover, it can support the electrode. For example, in an electrolytic cell, the knitting net can be used as a support net for the electrode to make the electrode closely close to the middle diaphragm.

[0003] In the prior art, when the knitting net is applied in the electrolysis field, it is usually stacked by multiple knitting net sheets in sequence, and then the combined body of multiple knitting net sheets is used to support the motor. However, this structure will inevitably lead to a large occupation of the electrolytic cell space, thereby reducing the relative content of the electrolyte and affecting the output of the electrolysis reaction; moreover, multiple knitting net sheets are abutted in sequence, resulting in poor air permeability; in addition, the cost of this structure will be greatly increased and the practicability is poor. Summary of the Utility Model

[0004] The embodiment of the utility model provides a double-layer cross elastic knitting net, aiming to solve the problem of poor practicability of the existing knitting net used in the electrolysis field.

[0005] To achieve the above object, the technical solution adopted by the utility model is: to provide a double-layer cross elastic knitting net, including silk threads, and a plurality of serrated nests are arranged at intervals on the silk threads, and the silk threads form a double-layer net body through the combination of the nests;

[0006] Wherein, the net surface of the double-layer net body is arranged in a corrugated shape.

[0007] In a possible implementation manner, each of the nests is an isosceles trapezoid outer shape structure.

[0008] In a possible implementation manner, each of the nests has two waist sides and a bottom side connected to the two waist sides.

[0009] In a possible implementation manner, it is set that the included angle between the waist side and the bottom side in each of the nests is a first included angle; it is set that the included angle between the extending direction of the corrugation on the double-layer net body and the bottom side is a second included angle;

[0010] The first included angle and the second included angle are set to be equal, so that one of the waist sides in each of the nests is perpendicular to the extending direction of the corrugation on the double-layer net body.

[0011] In a possible implementation, for any two adjacent ones of the nests, the length of the bottom edge in one of the nests is greater than that in the other nest, which is convenient for the weaving of the double-layer net body.

[0012] In a possible implementation, the silk thread includes at least two metal wires.

[0013] In this implementation, the serrated nests obtained by the silk thread bending itself can ensure mutual socketing to form an inseparable double-layer net body, which can have a certain elasticity. At the same time, the net surface formed by the double-layer net body is arranged in a corrugated shape, which can change the previous multi-layer stacking method, ensure the thickness in the transverse direction, and ensure a good elastic effect. At the same time, the air permeability effect of the mesh holes is ensured, and the cost is greatly reduced, and the practicability is strong. Description of the Drawings

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Please refer to Figure 1 and Figure 2 simultaneously, and now the double-layer cross elastic knitted net provided by the present utility model will be described. The double-layer cross elastic knitted net includes a silk thread 10, and a plurality of serrated nests 20 are arranged at intervals on the silk thread 10. The silk thread 10 forms a double-layer net body through the combination of the serrated nests 20.

[0020] Specifically, the net surface of the double-layer net body is arranged in a corrugated shape.

[0021] Compared with the prior art, for the double-layer cross-elastic knitted net provided in this embodiment, the serrated nests 20 formed by the bending of the silk thread 10 itself can ensure mutual socketing, forming an inseparable double-layer net body, which can have a certain elasticity. At the same time, the net surface formed by the double-layer net body is arranged in a corrugated shape, which can change the previous multi-layer stacking method, ensure the thickness in the transverse direction, and ensure a good elastic effect. At the same time, the air permeability effect of the mesh holes is ensured. In addition, the cost is greatly reduced, and the practicability is strong.

[0022] In this embodiment, regarding the thickness in the transverse direction, that is, the distance from the wave crest to the wave trough.

[0023] In some embodiments, the above-mentioned nests 20 can adopt the structure as Figure 1 shown. Refer to Figure 1 , each nest 20 has an isosceles trapezoid outer shape structure, which can facilitate the mutual socketing of each nest 20, facilitate knitting and manufacturing, and at the same time can ensure the appearance effect, with a simple structure and strong practicability.

[0024] It should be noted that the height of each nest 20 is set to be the same, and arc corners are provided at the corner points of the isosceles trapezoid. In addition, for the nest 20 with an isosceles trapezoid structure, an opening will be formed, and the opening degree (width) of the opening is smaller than the length of the bottom side 22. Refer to Figure 1 .

[0025] In some embodiments, the above-mentioned nests 20 can adopt the structure as Figure 1 shown. Refer to Figure 1 , each nest 20 has two waist sides 21 and a bottom side 22 connected to the two waist sides 21, with a simple structure, easy to bend and easy to manufacture.

[0026] In some embodiments, the above-mentioned double-layer net body can adopt the structure as Figures 1 to 2 shown. Refer to Figures 1 to 2 , it is set that the included angle between the extending direction of the upper corrugation of the double-layer net body and the bottom side 22 is the first included angle, and the included angle between the waist side 21 and the bottom side 22 in any one nest 20 is the second included angle, and the first included angle and the second included angle are set to be equal.

[0027] In the extending direction of the corrugation of the double-layer net body, the included angle with the bottom side 22 is 70°, which can ensure that one of the waist sides 21 in any one nest 20 is arranged in the same direction as the extending direction of the corrugation. Therefore, after the corrugation is formed, this waist side 21 will be in the plane where the corrugation is located, and thus it can ensure a good supporting effect. At the same time, because the two nests 20 are in a socketed structure, its elastic effect will also be enhanced, with a simple structure and strong practicability.

[0028] The value range of the second included angle is between 25° and 40°.

[0029] In this embodiment, the corrugation of the double-layer mesh body can be a sine folding waveform, which can be obtained by a rolling process after the double-layer mesh body is woven.

[0030] In some embodiments, the above-mentioned nesting 20 can adopt the structure as Figure 1 shown. Refer to Figure 1 , for any two adjacent nestings 20, the length of the bottom edge 22 in one nesting 20 is greater than the length of the bottom edge 22 in the other nesting 20. This structure can facilitate the weaving of the formed double-layer mesh body, facilitate the mutual sleeving of the nestings 20, and ensure that the double-layer mesh body is an inseparable structure.

[0031] In some embodiments, the above-mentioned silk thread 10 can adopt the structure as Figure 1 shown. Refer to Figure 1 , the silk thread 10 includes at least two metal wires. The setting of multiple metal wires can ensure an increase in the overall structural strength and a better support effect.

[0032] It should be noted that the double-layer cross elastic knitted mesh is woven by a silk thread 10 formed by combining at least two metal wires. This technology is a prior art and will not be elaborated here.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
