[0002] Copper tube, also known as red copper tube, is a kind of non-ferrous metal tube. It is a pressed and drawn seamless tube. Copper tube has good electrical and thermal conductivity. It is the main material for conductive accessories and heat dissipation accessories of electronic products. It has become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. Copper tube has strong corrosion resistance, is not easy to oxidize, and is not easy to react chemically with some liquid substances. It is easy to bend and shape.

[0003] The copper straight tube is named because of its straight shape. There are various ways to connect copper straight tubes, for example: copper straight tubes are connected with flange rings, copper straight tubes are connected with sockets. When the socket method is used for connection, one end of the copper straight tube is a socket and the other end is a spigot. The annular gap between the two ends is filled with interface materials. The interface materials can generally be rubber rings, expansive or asbestos cement. In special cases, blue lead interfaces can also be used.

[0004] However, after the copper straight tube is connected by the socket method, there is a risk of the connection of the copper straight tube falling off due to impact by external objects because there are no other fasteners to reinforce the connection. Therefore, it does not meet the existing needs. In this regard, we propose a copper straight tube with a socket joint. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, a copper straight tube with a socket joint, a first butt-end tube 2 is fixed at one end of the copper straight tube body 1, a second butt-end tube 3 is fixed at the other end of the copper straight tube body 1, two symmetrically distributed anti-dropout slots 4 are provided on the inner side of the first butt-end tube 2, two symmetrically distributed fixed metal plates 5 are fixed on the inner side of the second butt-end tube 3, the fixed metal plates 5 are bent in an L shape, an elastic bending connection plate 6 is fixed at one end of the fixed metal plate 5, a right-angle limit plate 7 is fixed at the other end of the elastic bending connection plate 6, and a guide inclined plate 8 is fixed at the other end of the right-angle limit plate 7; when the first butt-end tube 2 and the second butt-end tube 3 are connected, the right-angle limit plate 7 is clamped in the anti-dropout slot 4. The right-angle limit plate 7 is clamped in the anti-dropout slot 4 to increase the connection strength between the fixed metal plate 5 and the first butt-end tube 2, so as to ensure that when the first butt-end tube 2 is subjected to force in the axial direction, the first butt-end tube 2 and the second butt-end tube 3 cannot be separated.

[0023] Guide plates 9 are fixed on both sides of the right-angle limit plate 7. The guide plates 9 are quarter-circular arcs. When the second butt-joint end tube 3 is subjected to force and rotates around its own axis, the guide plates 9 are squeezed against the edge of the anti-slip groove 4. At this time, the guide plates 9 are disengaged from the anti-slip groove 4, and the right-angle limit plate 7 squeezes the elastic bending connecting plate 6 and the fixed metal plate 5, so that the elastic bending connecting plate 6 is deformed and the end of the fixed metal plate 5 approaches the axial direction of the first butt-joint end tube 2, so that the right-angle limit plate 7 is smoothly separated from the anti-slip groove 4, which facilitates the disassembly of the first butt-joint end tube 2 and the second butt-joint end tube 3, so that the copper straight tube body 1 can be recycled for secondary utilization, and the copper straight tube body 1 will not be damaged during the disassembly process.

[0024] The end portion of the elastically bent connecting plate 6 connected to the fixed metal plate 5 is bent in an arc shape, and the end portion of the elastically bent connecting plate 6 connected to the right-angle limiting plate 7 is inclined and has an angle of forty degrees with the inner wall of the first butt-joint end tube 2. The elastically bent connecting plate 6 with one end bent and the other end inclined has good elasticity. When squeezed, it bends and deforms toward the fixed metal plate 5, ensuring that the right-angle limiting plate 7 and the guide inclined plate 8 can smoothly enter the first butt-joint end tube 2.

[0025] The guide bevel 8 is tilted away from the right-angle limit plate 7 and points to the axis of the first butt-joint end tube 2. The angle between the right-angle limit plate 7 and the axis of the first butt-joint end tube 2 is forty-five degrees. When the inclined guide bevel 8 contacts the end of the first butt-joint end tube 2, the guide bevel 8 enters the inner side of the first butt-joint end tube 2 by being squeezed with the first butt-joint end tube 2. During this process, the guide bevel 8 applies pressure to the elastic bending connecting plate 6 and the fixed metal plate 5 through the right-angle limit plate 7, so that the elastic bending connecting plate 6 bends and deforms toward the fixed metal plate 5. At the same time, the end of the fixed metal plate 5 approaches the axis of the first butt-joint end tube 2, ensuring that the right-angle limit plate 7 and the elastic bending connecting plate 6 smoothly enter the first butt-joint end tube 2.

[0026] like Figure 2 and Figure 3 As shown, the ends of the first butt-joint end tube 2 and the second butt-joint end tube 3 away from the copper straight tube body 1 are both provided with sealing ring grooves 11, and the inner surface of the sealing ring groove 11 is provided with two annular positioning grooves, and the centers of the two annular positioning grooves located on the inner side of the same sealing ring groove 11 coincide with each other, and a sealing ring 10 is installed between the first butt-joint end tube 2 and the second butt-joint end tube 3, and the sealing ring 10 is clamped on the inner sides of the two sealing ring grooves 11, and the sealing ring 10 is used to seal and fill the gap between the first butt-joint end tube 2 and the second butt-joint end tube 3 to prevent the medium flowing inside the copper straight tube body 1 from leaking out from the gap at the connection between the first butt-joint end tube 2 and the second butt-joint end tube 3.

[0027] The inner and outer surfaces of the sealing ring 10 are both inlaid with reinforcement rubber rings 12, which are clamped in the annular positioning groove. The reinforcement rubber ring 12 is used to increase the friction between the sealing ring 10 and the sealing ring groove 11 and ensure the sealing of the gap between the sealing ring 10 and the sealing ring groove 11.

[0028] Working principle: align the ends of the first butt-jointed end tube 2 and the second butt-jointed end tube 3 and perform socket-joining operations, the guide inclined plate 8 first contacts with the first butt-jointed end tube 2 and squeezes with the inner edge of the end of the first butt-jointed end tube 2, because the guide inclined plate 8 is inclined, the guide inclined plate 8 slides into the inner side of the first butt-jointed end tube 2 during squeezing, and at the same time, the ends of the guide inclined plate 8 and the right-angle limit plate 7 apply pressure to the ends of the elastic bending connecting plate 6 and the fixed metal plate 5 through the right-angle limit plate 7, at this time, the elastic bending connecting plate 6 bends and deforms after being stressed, and at the same time, the end of the fixed metal plate 5 tilts and approaches toward the axial direction of the first butt-jointed end tube 2 until the guide inclined plate 8 and the right-angle limit plate 7 completely enter the first butt-jointed end tube 2, when the ends of the first butt-jointed end tube 2 and the second butt-jointed end tube 3 are close to each other or butt-jointed Before, the sealing ring 10 is clamped on the inner side of the sealing ring groove 11, and the first butt-joint end tube 2 and the second butt-joint end tube 3 are pressed tightly. When the ends of the first butt-joint end tube 2 and the second butt-joint end tube 3 are in contact with each other, the sealing ring 10 is completely clamped on the inner sides of the two sealing ring grooves 11, and at the same time, the right-angle limit plate 7 is aligned with the position of the anti-dropping groove 4. At this time, the fixed metal plate 5 and the elastically bent connecting plate 6 elastically recover, so that the right-angle limit plate 7 is clamped in the anti-dropping groove 4. At this time, when the first butt-joint end tube 2 and the second butt-joint end tube 3 are subjected to force in the axial direction, the right-angle limit plate 7 cannot be detached from the anti-dropping groove 4, thereby ensuring the stability and connection strength of the first butt-joint end tube 2 and the second butt-joint end tube 3 after connection, and the first butt-joint end tube 2 and the second butt-joint end tube 3 will not separate or fall off when hit by external objects.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
