Description

Technical Field

[0001] This utility model relates to the field of wear-resistant and pressure-resistant hose technology, specifically a multi-ribbed wear-resistant and pressure-resistant hose. Background Technology

[0002] Hose is an important component in modern industry for conveying fluids or protecting lines. It is characterized by flexibility, corrosion resistance and temperature resistance, and is widely used in industry, agriculture, food and other fields.

[0003] To enhance the pressure resistance of the outer and inner layers, a PVC multi-ribbed pressure-resistant hose (see patent number: 202022223798.X) has been developed. It includes an outer layer and an inner layer, with a fiber layer and a protective layer assembled between them. The outer layer has integrally formed reinforcing ribs. The circumferentially distributed reinforcing ribs on the sidewalls of the outer layer enhance its pressure resistance, thereby increasing the overall pressure resistance of the invention. Simultaneously, a protective layer between the outer and inner layers further strengthens the pressure resistance. This protective layer is composed of a first rubber block, a second rubber block, and a connecting layer, providing better support for both the outer and inner layers.

[0004] The outer rubber layer of the hose is its protective layer. Common failures include cracks and blistering. Cracks usually occur in cold environments. When the hose is bent, the outer rubber layer is prone to cracking, which reduces the service life of the multi-ribbed wear-resistant and pressure-resistant hose, thereby reducing its utilization rate. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-ribbed, wear-resistant, and pressure-resistant flexible hose to solve the problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-ribbed, wear-resistant, and pressure-resistant flexible hose, comprising a hose body, wherein a spiral protective layer is provided on the outer side of the hose body, and a reinforcing ring is provided inside the hose body;

[0007] The hose body includes a pipe, and the interior of the pipe is uniformly provided with multiple sets of annular grooves.

[0008] As a further embodiment of this utility model: multiple sets of annular filling layers are uniformly arranged inside the pipe, the annular filling layers are located inside the annular groove, and the annular filling layers are located at both ends of the inner side of the reinforcing ring and are fixedly connected to the annular groove.

[0009] As a further improvement of this utility model, each pair of annular filling layers has an arc-shaped structure on the side near the reinforcing ring.

[0010] As a further improvement of this utility model, the spiral protective layer is spirally wrapped around the outside of the pipe.

[0011] As a further improvement of this utility model, the reinforcing ring is a steel bar ring, and the reinforcing ring is used to reinforce the internal pressure of the pipeline.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting a spiral protective layer, a spiral protective layer is set on the outside of the pipe. The spiral protective layer increases the external friction resistance and wear resistance, ensuring its stability during use and storage. At the same time, when the hose is bent, it prevents the outer rubber layer from cracking, thus improving the service life of the multi-ribbed wear-resistant and pressure-resistant hose and increasing its utilization rate.

[0014] 2. The reinforcing ring can be directly placed at this position through the set annular groove, and the cross-section of the reinforcing ring is circular. This allows the expansion force generated by the structure to counteract the influence of external pressure, thereby making the pipeline more resistant to pressure when under stress, reducing the degree of deformation under stress, and improving the utilization rate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figures 1-3 In this embodiment of the utility model, a multi-ribbed wear-resistant and pressure-resistant hose includes a hose body 1, a spiral protective layer 2 is provided on the outside of the hose body 1, and a reinforcing ring 3 is provided inside the hose body 1.

[0022] The hose body 1 includes a pipe 101, and multiple sets of annular grooves 102 are uniformly arranged inside the pipe 101.

[0023] like Figures 1 to 3 As shown, multiple sets of annular filling layers 4 are uniformly arranged inside the pipe 101. The annular filling layers 4 are located inside the annular groove 102. The annular filling layers 4 are located at both ends inside the reinforcing ring 3 and are fixedly connected to the annular groove 102.

[0024] like Figures 1 to 3 As shown, each pair of annular filling layers 4 has an arc-shaped structure on the side near the reinforcing ring 3, so that the annular filling layer 4 and the reinforcing ring 3 are more closely fitted in the annular groove 102, thus ensuring the flatness of the inner wall of the pipe 101.

[0025] like Figures 1 to 3 As shown, the spiral protective layer 2 is spirally wrapped around the outside of the pipe 101. The spiral shape can increase the external friction resistance and wear resistance.

[0026] like Figures 1 to 3 As shown, the reinforcing ring 3 is a steel bar ring, and the reinforcing ring 3 is used to reinforce the internal pressure of the pipeline 101.

[0027] Working principle: During use, a spiral protective layer 2 is set on the outside of the pipe 101. The spiral protective layer 2 increases the external friction resistance and wear resistance, ensuring its stability during use and storage. At the same time, it prevents cracks in the outer rubber layer when the hose is bent, thus improving the service life of the multi-ribbed wear-resistant and pressure-resistant hose and increasing its utilization rate. Meanwhile, the reinforcing ring 3 can be directly set in the position through the set annular groove 102. The cross-section of the reinforcing ring 3 is circular, so the expansion force generated by this structure can be used to offset the influence of external pressure. This makes the pipe 101 more pressure-resistant when under stress, reduces its deformation under stress, and improves its utilization rate.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
