Description

Technical Field

[0001] The utility model relates to the technical field of metal hoses, in particular to a combined metal hose. Background Art

[0002] A metal hose is a flexible pipe connection element made of metal material. It has good bending ability and flexibility, and can withstand certain deformation and deflection in the pipe system. It plays an important role in modern industrial equipment. It is mainly used for transmitting media, especially for connecting various pump bodies. The pump body provides power to transmit various fluid media through the metal hose, such as water, oil, powder, etc. However, since the pump body now vibrates violently during operation, and the current metal hose is directly fixed to the pump body, the vibration generated by the pump body can be easily transmitted to the metal hose, causing the metal hose to shake violently, which can easily cause the transmission process of the fluid inside the hose to be unstable, affecting the transmission efficiency, and may also cause damage to the metal hose. Utility Model Content

[0003] The utility model provides a combined metal hose to achieve the purpose of reducing the vibration transmitted from a pump body to a hose body.

[0005] Furthermore, there are two bellows sections, which are correspondingly arranged at two ends of the hose body.

[0006] Furthermore, the bellows section corresponds to the access section.

[0007] Furthermore, the diameter of the folding disc is larger than the diameter of the hose body, and the diameters of the hose body, the access section, and the connecting section correspond to each other.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0019] As shown in the attached Figure 1 、 3As shown in Fig. -5, a combined metal hose of the present utility model includes a hose main body 1 and at least one corrugated pipe section 2. Both ends of the hose main body 1 are provided with access sections 3 for connecting to the transmission end. A connector 4 is arranged on the access section 3. The connector 4 is in the shape of a disc and is fixed on the access section 3. The connector 4 is provided with a connection hole 404, and a connection hole 404 is also arranged at the access port and is fixedly connected by screws. Specifically, reference can be made to the connection flange. Since the access section 3 does not have a structure for fixedly connecting to the access port, it needs to be fixedly connected through the connector 4. The corrugated pipe section 2 is fixedly arranged between the access section 3 and the hose main body 1. The access section 3, the hose main body 1 and the corrugated pipe can all be directly fixedly connected by welding. The corrugated pipe is composed of a plurality of folding discs 21 arranged. The cross-sections of the plurality of folding discs 21 are in a U shape. Adjacent folding discs 21 are connected by a connection section 22. A groove 400 is arranged inside the semi-circular ring 41. Specifically, the corrugated pipe is arranged at one end of the hose main body 1 close to the pump body. One end of the corrugated pipe is fixedly connected to the hose main body 1, and the other end is fixedly connected to the access section 3. When the pump body operates, vibrations will be generated. When the vibrations pass through the corrugated pipe section 2, the corrugated pipe section 2 can absorb the vibrations and a certain amount of impact force. Therefore, when the vibrations pass through the corrugated pipe section 2 to the hose main body 1, the vibrations will be greatly reduced. Further, the other end of the hose main body 1 far from the pump body does not need to be provided with a corrugated pipe, and the access section 3 can be directly used to connect to another pipeline or other equipment, containers, etc. By connecting the corrugated pipe at the end of the hose main body 1 of the present utility model, the direct connection between the hose main body 1 and the pump body is separated by the corrugated pipe, and the vibrations transmitted by the pump body are reduced by the corrugated pipe, effectively preventing the hose main body 1 from vibrating violently, thereby ensuring the stability of the fluid transmission inside the hose main body 1 and preventing the hose main body 1 from being damaged. However, the vibrations will be absorbed only after passing through the corrugated pipe section 2, and will be transmitted to the access section 3 before reaching the corrugated pipe section 2. It should be understood that the existing metal hoses are made of flexible materials and have a certain deformation ability. Therefore, it is not easy to directly connect to the access ports such as the pump body. Therefore, access sections 3 are provided at both ends of them. The access sections 3 are hard and not easily deformed to ensure the connection and fixation with the access ports. Since the access section 3 is made of a hard material and its connection with the access port is a hard connection, it is necessary to ensure the sealing and fixed connection between the access section 3 and the pump body access port as much as possible.

[0020] As Figure 2 shown, two corrugated pipe sections 2 are provided and are correspondingly arranged at both ends of the hose main body 1. The corrugated pipes can also be arranged at both ends of the hose main body 1, and then connected to the access section 3 through the corrugated pipes. For example, it can be used when the hose main body 1 needs to be used to connect two devices and vibrations are generated during the operation of both devices. The anti-vibration effect is better.

[0021] In this embodiment, the corrugated pipe section 2 corresponds to the access section 3. Specifically, the length of the corrugated pipe section 2 corresponds to the length of the access section 3.

[0022] In this embodiment, the diameter of the folding disc 21 is larger than that of the hose main body 1, and the diameters of the hose main body 1, the access section 3, and the connecting section 22 correspond to each other. That is, the folding disc 21 protrudes from each part of the metal hose. The same diameters of the remaining parts including the hose main body 1, the access section 3, and the connecting section 22 are beneficial for the fluid to be transmitted more uniformly and stably.

[0023] As Figure 6 As shown, the present technical solution provides another structure of the connector 4. The connector 4 includes two semi-circular rings 41. One end of the two semi-circular rings 41 is hinged to each other, and locking parts 401 are protruding from the other ends. The two semi-circular rings 41 can rotate relative to each other. There is a gap between the two locking parts 401, and the two locking parts 401 do not contact each other. They are fixedly connected by screws passing through the two locking parts 401. A convex edge 31 is protruding outward from the access section 3. A groove 400 is provided inside the semi-circular ring 41. During installation, first place the convex edge 31 of the access section 3 into the groove 400, and also place the connection port of the pump body into the groove 400, and fix it by locking the two locking parts 401 with screws. Further, sealing layers are provided both inside the groove 400 and on the access section 3.

[0024] The above embodiments are the preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto shall fall within the protection scope of the present utility model.
