Description

Technical Field

[0001] The utility model relates to the technical field of gas water heaters, and particularly to a quick insulating joint. Background Art

[0002] The joint of a gas water heater usually refers to the interface that connects the gas pipeline and the water heater. This joint plays a role of connection and sealing to ensure the normal gas supply of the gas water heater. The joint of a gas water heater is generally made of metal materials, such as copper, stainless steel or copper alloy. These materials have good corrosion resistance and sealing properties, and can resist corrosion and leakage of gas. When installing a gas water heater, the joint needs to be correctly connected to the gas pipeline and tightly sealed to prevent gas leakage.

[0003] However, the existing gas water heater joints often encounter the following problems when in use:

[0004] (1) Since the joint of the gas water heater needs to be used in conjunction with a corrugated connecting pipe, the length of the connectable pipe varies. If it is too long, it will take up space, and if it is too short, it will not be able to connect normally.

[0005] (2) If the water heater joints are aged or improperly installed during use, current will flow into the joints along the water body, causing leakage, posing a major safety hazard. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figure 1-3 As shown, a quick insulating joint includes: a main body 1, a first connector 2, a gas flow channel 3, a nut 4, a second connector 5, and an internal thread 6. The main body 1 is provided with a conveying channel, and the main body 1 is an insulating plastic. The insulating plastic has high heat resistance and good strength, and the use of the main body 1 material can improve the service life. One end of the first connector 2 is penetrated through the top of the channel of the main body 1, and the first connector 2 is fixedly connected to the contact surface of the main body 1. The gas flow channel 3 is provided on the first connector 2, and the gas flow channel 3 is connected to the conveying channel of the main body 1. The nut 4 is sleeved on the other end of the first connector 2, and the top of the second connector 5 is fixedly connected to the bottom of the main body 1. The internal thread 6 is arranged on the inner wall of the second connector 5, and the arrangement of the internal thread 6 provides conditions for subsequent connections.

[0036] In this embodiment, the washer 7 is placed on the inner diameter of the nut 4, the sealing gasket 8 is inserted into the inner diameter of the second connector 5, the outer surface of the sealing gasket 8 is provided with an external thread, the sealing gasket 8 is threadedly connected to the internal thread 6, one end of the fixing member 9 is threadedly connected to the second connector 5, and the sealing gasket 8 and the washer 7 are designed to form a sealing layer at the joint of the joint to prevent liquid or gas from leaking from the joint. The washer 7 can fill the uneven surface of the joint to ensure a reliable connection seal, and the washer 7 can reduce the vibration and impact of the joint during use, and reduce the possibility of loosening and wear. It has a certain elasticity and buffering performance, and can absorb the impact of external forces on the joint. The inner diameter of the sealing gasket 8 is narrow at the top and wide at the bottom. This arrangement facilitates the inner diameter of the narrower end to be connected to the gas flow channel 3 to prevent liquid from leaking from the connection gap between the second connector 5 and the main body 1. The metal slide 10 is semicircular. There are two metal slides 10. The two metal slides 10 are combined into a circle and placed between the fixing member 9 and the sealing gasket 8. The arrangement of the metal slide 10 can increase the sealing effect on the one hand. On the other hand, when the joint of the connecting pipe is narrow and cannot be connected, two metal slides 10 can be clamped on both sides of the interface and then connected. In this way, the metal slide 10 can play a filling and fixing effect, thereby improving the versatility of the product. The capping cover 11 is located above the nut 4. The capping cover 11 is fixedly connected to the nut 4. The capping cover 11 is used in an unconnected state to prevent the gasket from falling off.

[0037] It should be noted that the utility model is a quick insulating joint. When in use, when the connecting pipe is short, the interface of one pipe is passed through the fixing piece 9, and then two semicircular metal slides 10 are clamped on both sides of the top of the interface, and then the pipe interface is inserted into the second connecting head 5, and the fixing piece 9 is twisted. The fixing piece 9 is gradually tightened to drive the pipe interface to gradually squeeze the sealing gasket 8. At the same time, the pipe interface also drives the metal slides 10 on both sides to be gradually tightened. When it cannot be twisted anymore, the connection is completed. Finally, remove the capping cover 11, align the tail end of the other pipe with the first connecting head 2 and tighten the nut 4, and the two pipes are connected.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
