AI Technical Summary
Existing copper joints are prone to blockage due to freezing of water flow under low temperature conditions and may lead to bursting.
An anti-freeze-type copper joint is designed, which uses an electrical heat tray wrapped around the body of the copper joint, and through the cooperation of the knob and the compression ring, it ensures that the electrical heat tray is spirally wrapped outside the copper joint. As the external temperature decreases, the electrical heat tray emits heat after being energized, preventing the water flow in the copper joint body from freezing.
It effectively avoids the water flow in the copper joint body due to the low external temperature, ensuring the normal operation and service life of the copper joint.

[0004] When water flows in the three-way joint, if the external temperature is relatively low, it may cause the water flow in the three-way joint to freeze, thereby blocking the water flow in the three-way joint. At the same time, when the water freezes and expands, it is also easy to cause the three-way joint to burst. Content of the Utility Model
[0005] The purpose of the utility model is to provide an anti-freezing copper joint, which can avoid the situation that the water flow in the copper joint body freezes due to too low external temperature.
[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an anti-freezing copper joint includes a copper joint body, two first connectors located on the left and right sides of the copper joint body, a first thread surface opened at one end of the first connector far from the copper joint body, a second connector arranged on the upper side of the copper joint body, a second thread surface opened on the second connector, and also includes an electric heating tape spirally wound outside the copper joint body. The second thread surface extends to one side of the electric heating tape, a knob is threadedly connected to the second thread surface, and a pressing ring for pressing the electric heating tape against the outer wall of the first connector is arranged below the knob.
[0007] The further setting of the utility model is that a positioning ring is arranged on the first connector at a position outside the pressing ring.
[0008] The further setting of the utility model is that anti-slip grooves are opened on the circumferential side of the knob.
[0009] A further setting of the present utility model is that: the outer side of the copper joint body is wrapped with a heat-preserving sponge sleeve in an inverted T shape.
[0010] A further setting of the present utility model is that: on one outer wall of the heat-preserving sponge sleeve, there is an inverted T-shaped disassembly and assembly opening.
[0011] A further setting of the present utility model is that: the outer side of the electric heating tape is wrapped with an explosion-proof braided net.
[0012] To sum up, the present utility model has the following beneficial effects:
[0013] 1. The electric heating tape is spirally wound around the copper joint body. By using the knob threadedly connected on the second thread surface, after rotating the knob, the pressing ring can be driven to move towards the side close to the electric heating tape, and then the pressing ring can press the electric heating tape against the outer wall of the first connector. At this time, the electric heating tape can be stably spirally wound around the copper joint body; when the external temperature is relatively low, the electric heating tape can be powered on, and after the electric heating tape emits heat, it can keep the copper joint body warm, and finally the situation that the water flow in the copper joint body freezes due to the too low external temperature can be avoided.
[0014] 2. When the pressing ring presses the electric heating tape against the outer wall of the first connector, the positioning ring on the first connector is used to position the electric heating tape, and finally it is further beneficial to stably spiral the electric heating tape around the copper joint body;
[0015] 3. By using the anti-slip groove opened on the periphery of the knob, the anti-slip groove can play an anti-slip role and is beneficial to stably rotate the knob;
[0016] 4. By using the heat-preserving sponge sleeve to wrap the outer side of the copper joint body, at this time, the electric heating tape and the copper joint body can be wrapped by the heat-preserving sponge sleeve, reducing the heat loss of the electric heating tape due to heat exchange with the outside air, and finally it is beneficial to energy conservation and environmental protection;
[0017] 5. By using the inverted T-shaped disassembly and assembly opening opened on one outer wall of the heat-preserving sponge sleeve, it is beneficial to conveniently disassemble and assemble the heat-preserving sponge sleeve wrapped on the copper joint body through the disassembly and assembly opening;
[0018] 6. By using the explosion-proof braided net wrapped on the outer side of the electric heating tape, the explosion-proof braided net can wrap and protect the electric heating tape, which is beneficial to improving the service life of the electric heating tape. Description of the Drawings

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0025] An anti-freezing copper joint, referring to Figure 1 , this anti-freezing copper joint includes a copper joint body 1, a first connector 2, a first threaded surface 21, a second connector 3, a second threaded surface 31 and an electric heating tape 4. Among them, there are two first connectors 2 and they are integrally arranged on the left and right sides of the copper joint body 1, and the first threaded surface 21 is opened at the end of the first connector 2 away from the copper joint body 1; at the same time, the second connector 3 is integrally arranged on the upper side of the copper joint body 1, and the second threaded surface 31 is opened on the second connector 3; among them, the electric heating tape 4 is spirally wound outside the copper joint body 1. The electric heating tape 4 is composed of a conductive polymer, two parallel metal wires and an insulating protective layer. By energizing the electric heating tape 4, the electric heating tape 4 can release heat. At the same time, the outside of this electric heating tape 4 is wrapped with an explosion-proof braided net.
[0026] Referring to Figure 1 , Figure 2 , Figure 3, the second threaded surface 31 extends to one side of the electric tracing band 4, and a knob 5 is threadedly connected to the second threaded surface 31. An anti-slip groove 52 is provided on the circumferential side of the knob 5. A pressing ring 51 is integrally provided on the lower side of the knob 5. The pressing ring 51 can be used to press the electric tracing band 4 against the outer wall of the first connector 2. At the same time, a positioning ring 22 is integrally provided on the first connector 2 at a position outside the pressing ring 51. A heat-insulating sponge sleeve 6 in an inverted T shape is further wrapped outside the copper joint body 1, and an inverted T-shaped disassembly and assembly opening 61 is provided on the outer wall of one side of the heat-insulating sponge sleeve 6.
[0027] Principle: By using the knob 5 threadedly connected to the second threaded surface 31, after rotating the knob 5, the pressing ring 51 can be driven to move towards the side close to the electric tracing band 4. Subsequently, the pressing ring 51 can press the electric tracing band 4 against the outer wall of the first connector 2. Then, the positioning ring 22 on the first connector 2 is used to position the electric tracing band 4, which is beneficial to the stable spiral winding of the electric tracing band 4 outside the copper joint body 1. When the outside temperature is relatively low, the electric tracing band 4 can be powered on. After the electric tracing band 4 emits heat, heat preservation treatment is carried out on the copper joint body 1. Finally, the situation that the water flow in the copper joint body 1 freezes due to the too low outside temperature can be avoided.
