[0002] A union is a common pipe connector that can be easily installed and disassembled. It can also be called a flexible joint or a detachable connector. It is very common in life and is used in the operation of many mechanical equipment. Because mechanical equipment will produce friction, impact and other wear during production, the design of the union can reduce the contact area between mechanical components and relieve pressure. At the same time, the union has a reasonable design, simple operation, strong practicality, and extremely high leak-proof ability. Therefore, it is widely used in pipes of different calibers and water meters, valves and other equipment.

[0003] In the prior art, many pipe joints are connected by flanges. Although flange connections can also make the pipes tightly connected, the stress generated when the bolts are tightened during connection can easily cause damage to the flanges or even the pipes. Secondly, flange connections have a greater risk of leakage and require regular maintenance, which increases the cost of decoration and subsequent maintenance. In addition, the prescribed steps must be strictly followed during installation, which makes it inconvenient to operate during installation, and it is difficult to change or discover errors after installation, which can easily affect the normal operation of mechanical equipment and cause a lot of inconvenience.

[0021] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0022] Reference Figure 1-4 The utility model provides an embodiment of a novel safe low-temperature transition joint, comprising a first pipe 1, one end of the first pipe 1 is fixedly connected to a first connecting piece 2, the other end of the first connecting piece 2 is fixedly connected to two positioning blocks 3, both ends are fixedly connected to the positioning blocks 3, so that the first connecting piece 2 and the second connecting piece 6 are more firmly connected, the stability of the two connecting pieces is increased, and the positioning block 3 can be more convenient for the connection of the telescopic block 4 on the positioning block 3, and a limiting groove 10 is provided inside the positioning block 3.

[0023] One end of the positioning block 3 is movably connected to the telescopic block 4. The installation of the telescopic block 4 can achieve faster clamping of the first connecting member 2 and the second connecting member 6, and further increase the stability of the connection between the two connecting members. The other side of the first connecting member 2 is installed with the second connecting member 6 corresponding to the first connecting member 2, and the other end of the second connecting member 6 is fixedly connected to the second pipe 7.

[0024] A spring 9 is fixedly connected to the bottom of the limit groove 10, and the other end of the spring 9 is fixedly connected to the limit plate 8. The other end of the limit plate 8 is fixedly connected to one end of the telescopic block 4. The limit plate 8 moves inside the limit groove 10. The opening of the limit groove 10 can prevent the position of the spring 9 inside the limit groove 10 from shifting when it is squeezed and generates a reaction force, and further enables the telescopic block 4 to be quickly connected with the second through groove 14. At the same time, the limit plate 8 can also prevent the position of the telescopic block 4 from shifting when it is squeezed and popped out, thereby making the connection between the first connecting member 2 and the second connecting member 6 faster and more convenient.

[0025] A first through slot 5 is provided at one end of the second connecting member 6, and a second through slot 14 is provided outside the first through slot 5. The first through slot 5 corresponds to the positioning block 3 on the first connecting member 2, and the second through slot 14 corresponds to the telescopic block 4 on the positioning block 3. The first through slot 5 is provided to facilitate the clamping of the positioning block 3, thereby facilitating a better corresponding clamping of the telescopic block 4 on the positioning block 3 and the second through slot 14 inside the first through slot 5, and also facilitates quick and convenient disassembly at a later time.

[0026] The second connecting member 6 is provided with a first threaded hole 11 at the end away from the first through groove 5, and the first connecting member 2 is provided with a second threaded hole 12 at the end away from the positioning block 3, and the two are connected by a screw 13. The threaded holes provided above the first connecting member 2 and the second connecting member 6 correspond to each other, and the connection is achieved by using the screw 13, which further strengthens the firmness of the connection between the first connecting member 2 and the second connecting member 6, and also strengthens the air tightness between the connecting members.

[0027] Working principle: First, the first connecting member 2 is connected to the first pipe 1 through threads, and then the second connecting member 6 is connected to the second pipe 7 at the other end through threads. Because the positioning block 3 is fixedly connected to one side of the first connecting member 2, and a first through groove 5 is opened at the position of the second connecting member 6 corresponding to the positioning block 3 on the first connecting member 2, and a second through groove 14 is opened outside the first through groove 5, when the first connecting member 2 is pushed inward, the telescopic block 4 on the first connecting member 2 is squeezed by the inner side of the second connecting member 6, because the telescopic block 4 is fixedly connected to the limiting plate 8 inside the fixed limiting groove 10, the telescopic block 4 will be squeezed inside the limiting groove 10. The limiting plate 8 will further squeeze the spring 9 inside the limiting groove 10, so that the telescopic block 4 will shrink toward the inside of the positioning block 3. When the positioning block 3 moves to the second through groove 14 inside the second connecting member 6, the spring 9 has no squeezing force and will generate a reaction force. This reaction force will cause the telescopic block 4 to pop out, so that the telescopic block 4 will just be connected with the second through groove 14. After the connection is completed, because the first connecting member 2 and the second connecting member 6 are respectively provided with a first threaded hole 11 and a second threaded hole 12, the two threaded holes correspond to each other, and then the threaded holes at both ends are threadedly connected with a screw 13, so that the first connecting member 2 and the second connecting member 6 are finally connected and clamped.

[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
