The tube body has symmetrically welded joints at both ends, and an inner liner is fixed to the inner wall of the tube body. The joints have mounting holes, and an annular groove is formed on the end face of the joint facing away from the tube body. The connecting blocks are symmetrically and movably placed within the annular grooves, and fixing blocks are welded to both connecting blocks. An insertion groove is formed on the end face of the fixing block facing away from the connecting block. Insert blocks are welded to both ends of the steel wire, and the insert blocks are movably inserted into the insertion grooves. The fixing blocks and insert blocks are connected to each other by a pin, one end of which penetrates the fixing block and extends into the insert block. This utility model has a simple structure, is easy to use, provides tensile strength to metal flexible hoses, increases their application range, extends the service life of metal flexible hoses, and meets consumer needs.

[0004] The aforementioned patent addresses the shortcomings of existing metal corrugated pipes, which are generally made of galvanized or non-galvanized low-carbon steel strips spirally folded and interlocked. Due to their structural composition, they do not possess tensile strength and are easily damaged in high-tensile environments. This application provides another solution to the problems raised in the aforementioned patent. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tensile-resistant metal hose reinforcement structure with the advantage of good tensile strength. It solves the problem that existing metal corrugated pipes are generally made of galvanized or non-galvanized low-carbon steel strips spirally folded and interlocked, and due to their structural composition, they do not have tensile strength. In current high-tensile-force usage environments, the hoses are easily damaged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tensile-resistant metal hose reinforcement structure, comprising a hose body, wherein the hose body is provided with a tensile and compressive resistance mechanism;

[0007] The tensile and compressive resistance mechanism includes connecting flanges fixedly installed at both ends of the hose body. A wire mesh protective sleeve is fixedly installed between the opposite surfaces of the two connecting flanges. A compression ring is fixedly installed on the inner surface of the wire mesh protective sleeve. A connecting rod is fixedly installed on the inner side of the connecting flange. A tensile rope extending into the interior of the hose body is fixedly installed on the surface of the connecting rod.

[0008] Furthermore, the hose body is located inside the wire mesh protective sleeve, and the pressure-resistant ring is fixedly installed on the outer surface of the hose body.

[0009] Furthermore, there are multiple pressure-resistant rings, which are evenly distributed on the outer surface of the hose body.

[0010] Furthermore, rubber particles are filled between the outer surface of the hose body and the inner surface of the wire mesh protective sleeve.

[0011] Furthermore, the surface of the connecting flange is provided with fixing holes, and the number of fixing holes is evenly distributed on the surface of the connecting flange.

[0012] Furthermore, tensile-resistant wires are fixedly installed inside the wall of the wire mesh protective sleeve.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This tensile-resistant metal hose reinforcement structure, through the installation of tensile ropes and tensile wires, can prevent the hose body and wire mesh protective sleeve from being excessively stretched, leading to hose body breakage. At the same time, the hose body is equipped with an anti-compression ring to prevent the hose body from being squeezed and affecting its normal use. This solves the problem that the existing metal corrugated pipes are generally made of galvanized or non-galvanized low carbon steel strips spirally folded and interlocked. Due to their structural composition, they do not have tensile strength and are easily damaged in current high-tensile environments. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1 to 2 This embodiment of a tensile-resistant metal hose reinforcement structure includes a hose body 1, on which a tensile and compressive-resistant mechanism is provided. The tensile and compressive-resistant mechanism includes connecting flanges 2 fixedly installed at both ends of the hose body 1, a wire mesh protective sleeve 3 fixedly installed between the opposite surfaces of the two connecting flanges 2, a compression ring 4 fixedly installed on the inner surface of the wire mesh protective sleeve 3, the hose body 1 being located inside the wire mesh protective sleeve 3, the compression ring 4 being fixedly installed on the outer surface of the hose body 1, and there are multiple compression rings 4 evenly distributed on the outer surface of the hose body 1. A connecting rod 5 is fixedly installed inside the connecting flange 2, and a tensile rope 6 extending into the interior of the hose body 1 is fixedly installed on the surface of the connecting rod 5.

[0020] Rubber particles 9 are filled between the outer surface of the hose body 1 and the inner surface of the wire mesh protective sleeve 3. Fixing holes 7 are opened on the surface of the connecting flange 2. The number of fixing holes 7 is evenly distributed on the surface of the connecting flange 2. Tensile wires 8 are fixedly installed inside the wall of the wire mesh protective sleeve 3.

[0021] It should be noted that the wire mesh protective sleeve 3 in this embodiment is made of woven metal wire.

[0022] It should be noted that the tensile wire 8 in this embodiment is made of multiple metal wires wound and woven together.

[0023] It should be noted that the tensile rope 6 in this embodiment is made of multiple polyethylene filaments wound and woven together.

[0024] It should be noted that the rubber particles 9 in this embodiment are mixed with adhesive, which facilitates the bonding of the hose body 1 and the wire mesh protective sleeve 3 together.

[0025] The working principle of the above embodiments is as follows:

[0026] During use, the anti-tension rope 6 and anti-tension wire 8 can prevent the hose body 1 and the wire mesh protective sleeve 3 from being overstretched, which would cause the hose body 1 to break. The anti-pressure ring 4 can prevent the hose body 1 from being squeezed and affecting the flow of liquid. The rubber particles 9 can improve the buffering performance between the hose body 1 and the wire mesh protective sleeve 3, and at the same time improve the connection stability between the hose body 1 and the wire mesh protective sleeve 3.
