Description

Technical Field

[0001] The utility model relates to the technical field of metal hoses, and particularly to a metal hose that is convenient to replace. Background Art

[0002] A metal hose is a flexible connector commonly used in pipeline systems. It is made of metal materials and has good flexibility, compressive resistance, and corrosion resistance. In some scenarios where normal hardware connecting pipes cannot be used for pipe fittings connection, the connection of the metal hose not only meets the sealing performance during pipe fittings connection but also has adjustability for the connection position and angle between two pipe fittings, making the installation of pipe fittings more flexible in some cases.

[0003] When installing two existing metal pipe fittings, they are generally simply connected with cable ties. Although it is relatively simple to disassemble, in actual use, the connection of the pipe fittings is prone to come apart, and the outer skin of the metal hose is easily damaged under the pressure of the cable ties once there is frequent shaking at the connection of the pipe fittings, which is equivalent to sacrificing the service life of the metal hose for the convenience of disassembly and assembly. And actually, tools such as scissors are needed for assistance during disassembly.

[0004] Therefore, it is necessary to design a metal hose that is convenient to replace to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a metal hose that is convenient to replace, so as to solve the technical problems raised in the above background art.

The third insertion ring is slidably arranged inside the third slots on both sides. A fixing ring is fixedly sleeved on the outer surface of the third insertion ring. Two symmetric insertion limiting blocks are fixedly connected to one side of the fixing ring. Insertion columns are elastically arranged on the outer surface of the fixing ring on one side of the two insertion limiting blocks. Both ends of the two insertion columns are respectively slidably inserted into the two jacks on the same side. Connecting blocks are fixedly connected to the tops of the two insertion columns. The two insertion limiting blocks are respectively slidably inserted into one side of the two connecting blocks.

[0007] Preferably, an equipment slot is provided on one side of the third insertion ring. Two symmetric pressing blocks are fitted on one side of the inner cavity of the equipment slot. First springs are fixedly connected between the pressing blocks and the other side of the inner side of the equipment slot. The bottom ends of the two insertion columns are respectively fixedly inserted into the two pressing blocks.

[0008] Preferably, the connecting block is an arc-shaped block. The top of the connecting block is flush with the outer surface of the insertion pipe. The connecting block is fixedly connected to the outer surface of the third insertion ring away from the third slot.

[0009] Preferably, a pipe body connecting plug is fixedly connected to the inner wall of the insertion pipe. The two sides of the pipe body connecting plug are respectively flush with the two sides of the insertion pipe. The diameter of the first slot is larger than the diameter of the jack.

[0011] The technical solution provided by the present utility model has the following beneficial effects compared with the prior art:

[0012] The utility model drives the horizontal elastic sliding of the third insertion ring through a fixing ring, thereby using two insertion limiting blocks to limit the lifting of a connecting block. When the metal hose body is connected to an insertion pipe, by separating the two insertion limiting blocks from the two connecting blocks, it is convenient to pull out the two connecting blocks. Two insertion posts are respectively inserted into the two jacks arranged on two limiting insertion blocks on the outer surface of the second insertion ring, thereby completing the connection between the metal hose body and the two insertion pipes. Then, the two insertion pipes are used to connect to a connecting pipe body, so as to complete the pipe body connection without pressing on the outer skin of the metal hose body, and thus, while being convenient for disassembly, the service life of the device will not be reduced.

However, the utility model can also be implemented in other ways different from those described herein. Therefore, the utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0020] Please refer to Figures 1-4The utility model provides a metal hose that is easy to replace, including a metal hose body 1, characterized in that: the inner walls of both ends of the metal hose body 1 are fixedly connected with second plug rings 6, and the outer surfaces of the two second plug rings 6 are fixedly connected with two symmetrical limit plug blocks 7, and the outer surfaces of the limit plug blocks 7 are each provided with a plug hole 8, and the outer surfaces of the two second plug rings 6 are both slidably connected with a plug tube 2, and the plug tube 2 is provided with a first slot 9 and two second slots 10 on the outer surface of one side of the metal hose body 1, and the second plug ring 6 and the two limit plug blocks 7 on the same side are respectively slidably connected to the inside of a first slot 9 and the two second slots 10, and the outer surface of the plug tube 2 is provided with a groove, and the inner wall of the groove is provided with a second slot 9 on both sides.
