Technical Field
[0001] The utility model relates to the technical field of stainless steel wire braided hoses, and particularly to a stainless steel wire braided hose with a corner elbow. Background Technique
[0002] A stainless steel wire braided hose is a hose product braided from stainless steel wires, mainly used for various pipe connections, and has good pressure resistance, corrosion resistance and wear resistance.
[0003] The main raw material of the stainless steel wire braided hose is stainless steel wire, usually using stainless steel materials such as 304 and 316. These materials have good corrosion resistance and mechanical properties, which can ensure the service life and safety of the hose. The inner layer of the hose usually uses rubber or other synthetic materials to ensure the sealing performance and the smoothness of fluid transmission.
[0004] In terms of structure, the stainless steel wire braided hose is composed of a stainless steel wire braided layer and an inner layer material. The braided layer forms a net structure through cross-braiding, enhancing the pressure resistance and tensile strength of the hose. At the same time, the inner layer material closely adheres to the inner side of the braided layer, forming a smooth fluid channel for easy fluid transmission. The stainless steel wire braided hose is widely used in fluid transmission systems such as water, gas, and oil in the fields of home, industry, and agriculture.
[0005] The stainless steel wire braided hose with a corner elbow is a specially designed pipe connection product. On the basis of maintaining the excellent performance of the stainless steel wire braided hose, it adds a corner elbow, making it more flexible and applicable in pipe systems that require bending or turning.
[0006] When the existing corner elbow of the stainless steel wire braided hose works in an environment where it often encounters heat and cold exchange, the stainless steel material will expand and contract due to heat and cold alternation. This frequent temperature change may cause stress at the connection between the corner elbow and the hose, and then may lead to poor sealing or loosening of the connection; therefore, it does not meet the existing requirements, and for this reason, we propose a stainless steel wire braided hose with a corner elbow.

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example 1: This embodiment aims to solve the problem of the existing stainless steel wire braided hose corner elbow 112 working in an environment where it is often exposed to heat exchange. The stainless steel material will expand and contract when it experiences alternating heat and cold. Such frequent temperature changes may cause stress in the connection between the corner elbow 112 and the hose, which may lead to poor sealing or loose connection. Please refer to Figures 1 - 6 A stainless steel wire braided hose with a corner elbow includes a first hose 110, a second hose 111 and a corner elbow 112. A first tube head 113 is provided at one end of the corner elbow 112, and a second tube head 114 is provided at the other end of the corner elbow 112. The first hose 110 is inserted into the first tube head 113, and the second hose 111 is inserted into the second tube head 114. Connecting rings 115 are installed at the ends of the first tube head 113 and the second tube head 114, and an internal threaded ring 116 is provided in the connecting ring 115. External threaded rings 117 are provided on the outside of the first hose 110 and the second hose 111. The internal threaded ring 116 is threadedly matched with the external threaded ring 117. A reinforcing component 120 is provided in the corner elbow 112.
[0028] The reinforcement assembly 120 includes a reinforcement plate 121 arranged in the corner elbow 112, and the reinforcement plate 121 is arranged as a first plate body 122 and a second plate body 123. A connecting rod 124 is arranged between the first plate body 122 and the second plate body 123. A groove 125 is opened in the connecting rod 124, and the first plate body 122 and the second plate body 123 are inserted into the groove 125. A connecting spring 126 is arranged in the groove 125, and the connecting spring 126 connects the first plate body 122 and the second plate body 123.
[0029] The first plate 122 and the second plate 123 are both arc-shaped plates. They are symmetrically arranged within the corner elbow 112 with a connecting rod 124. A retaining groove 127 corresponding to the connecting rod 124 is defined within the corner elbow 112, and the connecting rod 124 engages with the retaining groove 127. Sliders 128 are mounted on the ends of the first plate 122 and the second plate 123. A sliding groove 129 corresponding to the sliding groove 128 is defined within the groove 125. The sliding groove 129 communicates with the groove 125, and the sliding groove 128 slides and engages within the sliding groove 129.
[0030] The first hose 110 and the second hose 111 are respectively inserted into the first pipe head 113 and the second pipe head 114 of the corner elbow 112. The first hose 110 and the second hose 111 are fixed to both ends of the corner elbow 112 through the threaded engagement of the external threaded ring 117 and the internal threaded ring 116.
[0031] In alternating hot and cold environments, the corner elbow 112 experiences thermal expansion and contraction. The curved design of the first and second plates 122, 123, and the connecting spring 126 alleviate stress caused by this expansion and contraction, preventing loosening of the connection. The interlocking design of the connecting rod 124 and the retaining groove 127 ensures the stability and torsional resistance of the reinforcement assembly 120 within the corner elbow 112.
[0032] The sliding insertion of slider 128 within slot 129 further enhances the flexibility of reinforcement assembly 120, enabling fine-tuning under stress and maintaining overall stability. The threaded engagement of internally threaded ring 116 and externally threaded ring 117 ensures a tight seal at the joint, preventing fluid leakage. The design of reinforcement assembly 120 not only improves the stress resistance of corner elbow 112 in alternating hot and cold environments but also enhances its overall structural strength and sealing performance.
[0033] In this embodiment: by setting the reinforcing plate 121, the connecting rod 124 and the supporting spring, the stress caused by thermal expansion and contraction can be relieved, and the loosening of the connection can be prevented. At the same time, the stability and torsional resistance of the reinforcing component 120 in the corner elbow 112 are ensured. The threaded cooperation between the internal threaded ring 116 and the external threaded ring 117 ensures the sealing performance of the connection and prevents fluid leakage, thereby not only improving the stress resistance of the corner elbow 112 in a hot and cold alternating environment, but also enhancing the overall structural strength and sealing performance.
[0034] Example 2: This example is intended to further alleviate the stress concentration phenomenon at the connection between the corner elbow 112 and the hose, thereby reducing the risk of loosening of the connection. This example is an improvement made on the basis of Example 1. For details, please refer to Figures 1 - 6. A heat preservation layer 130 is provided outside the reinforcing plate 121, and the heat preservation layer 130 is set as a heat preservation sponge layer. A sealing film 131 is arranged between the external thread ring 117 and the internal thread ring 116, and the sealing film 131 is set as a rubber film. A sealing ring 132 is sleeved inside the connecting ring 115, and the sealing ring 132 is set as a rubber ring. The rubber ring plays a role in filling the gap inside the connecting ring 115, increasing the sealing performance at the connection. Under any working conditions, the rubber ring can ensure the tightness at the connection and prevent fluid leakage.
[0035] In this embodiment: By using a heat preservation sponge layer for the heat preservation layer 130, the heat transfer speed between the inside and outside of the corner elbow 112 can be effectively slowed down, the frequent temperature changes caused by the alternation of cold and heat can be reduced, so as to reduce the stress caused by thermal expansion and contraction, and further relieve the stress concentration phenomenon at the connection between the corner elbow 112 and the hose, thereby reducing the risk of loosening at the connection. By arranging a rubber film between the external thread ring 117 and the internal thread ring 116, the sealing performance of the rubber is increased, and it can effectively prevent poor sealing caused by vibration or small displacement.
