Description

TECHNICAL FIELD

[0001] The utility model relates to a three-in-one water stop pipe joint with quick disassembly, in particular to a pipe joint used in waterway engineering, which can be quickly and stably mounted or dismounted with at least one connecting pipe. BACKGROUND

[0002] Currently, the connection between existing water pipes and water pipes is mainly achieved by forcing the pipe joint to be connected between the pipes, in order to avoid leakage at the connection between the pipe and the pipe joint, an adhesive is usually applied to the outer wall of the pipe and the inner wall of the pipe joint, so that the pipe and the pipe joint are adhered to each other, thereby achieving stable connection between the pipes and avoiding water leakage. This method is mainly used in plastic pipe engineering.

[0003] In addition, the pipe can also be connected by screwing at a higher cost, which involves applying a rubber ring to the inner wall of the pipe joint, and then using the pipe joint to be screwed and connected to the pipe joint, so that the rubber ring is tightly forced to the outer wall of the pipe, thereby achieving forced connection and preventing leakage between the pipe and the pipe joint.

[0004] However, the above-mentioned connection between the pipe and the pipe joint has many problems, such as:

[0005] 1. The pipe and the pipe joint are adhered to each other by using an adhesive, which not only complicates the construction process and is not reliable, but also when the pipe and the pipe joint are adhered, if the pipe path needs to be changed or modified during construction, the pipe and the pipe joint cannot be disassembled and reassembled, and the pipe and the pipe joint must be completely cut off and discarded, and the pipe joint and the connected pipe must be reassembled, which not only increases the cost of pipe engineering accessories, but also wastes time and labor, making the assembly very uneconomical and inconvenient, which not only has no environmental benefits, but also greatly increases the construction cost.

[0006] 2. After the pipe and the pipe joint are adhered, the adhesive will harden and age in a short period of time, which will easily cause fragmentation and rupture problems. Once the pipe and the pipe joint are hit or shaken by external force (such as earthquake), the connection between the pipe and the pipe joint will inevitably cause leakage and even pipe breakage problems, and the repair of such problems is the most difficult and most costly problem in water and electricity engineering pipe repair.

[0007] 3. Using a screw-locking method with a rubber ring to tighten between the pipe and fitting is not only relatively expensive for piping projects, but also, because the rubber ring (circular in shape) only tightens the pipe and fitting without any other fixing design structure, the pipe and fitting are easily deformed and gapped due to displacement when subjected to external force or vibration (such as earthquake shaking), resulting in micro-leakage. Alternatively, if the rubber ring is not installed carefully during piping installation, it may twist, curl, or break during the screw-locking process. These are the main factors causing leakage at the connection between the pipe and fitting.

[0008] Therefore, the main problem to be solved by this utility model is how to develop a pipe joint structure that can be quickly and securely installed or disassembled with at least one connecting pipe. Utility Model Content

[0009] The main objective of this utility model is to provide a quick-disassembly three-in-one water-stop pipe joint, comprising a pipe joint, at least two three-in-one water-stop components, and multiple toothed plates. The pipe joint can be a straight-through joint, a tee joint, a T-joint, or other types of joint, and has at least two pipe interfaces. Each pipe interface has a constricted portion at its opening, making the pipe interface conical. The at least two three-in-one water-stop components are disposed inside each pipe interface. Each three-in-one water-stop component includes a ring, a leak-proof ring, and multiple elastic arms. The ring has a top and a bottom end, is conical in shape, and contacts the inner wall of the pipe interface. The sidewall of the ring... The ring has multiple bite grooves; the leak-proof ring and the bottom of the ring body are spaced apart, and the leak-proof ring is in contact with the inner wall of the pipe interface; multiple elastic arms are arranged opposite to each other and connected between the ring body and the leak-proof ring, so that the ring body, the leak-proof ring and the multiple elastic arms are formed as a single unit; secondly, a compression space is formed between the ring body and the leak-proof ring, which enables the ring body to have an elastic compression and elastic reset mechanism; multiple bite plates are arranged opposite to each other in the multiple bite grooves of the ring body, and these bite plates have multiple protruding bite parts on one side and a beveled part on the other side, with the bite parts facing the inside of the ring body and the beveled part facing the outside of the ring body and correspondingly engaging with the inner wall of the pipe interface.

[0010] When the pipe fitting is connected to an externally pre-set connecting pipe, simply insert the connecting pipe into the pipe interface and the three-in-one water-stop component of the pipe fitting. Then, pull the connecting pipe in the opposite direction. Because both the pipe interface and the ring are conical, the ring and multiple teeth can clamp and bite the connecting pipe, preventing the connecting pipe from detaching from the pipe interface of the pipe fitting. Furthermore, the leak-proof ring is positioned between the inner wall of the pipe interface and the outer wall of the connecting pipe to form a seal, ensuring a complete and sealed connection between the pipe fitting and the connecting pipe. This allows for quick and stable installation of the pipe fitting and the connecting pipe.

[0011] When the pipe joint is to be separated from the connected connecting pipe, the ring body is extruded from the outside to the inside by an external tool (such as a thin sharp thorn or a screwdriver), so that the ring body and the plurality of tooth pieces move to the inside of the pipe joint, so that the ring body and the plurality of tooth pieces are out of position and release the forced bite on the connecting pipe, and the connecting pipe is quickly separated from the pipe interface of the pipe joint.

[0012] The expansion groove is arranged at the bottom of the ring body.

[0013] The inner wall of the pipe interface is provided with an embedding groove relative to the position away from the opening.

[0014] The elastic arm is in one of a curved arc shape, a curved shape or a sawtooth shape.

[0015] The pipe interface is tapered from the inside to the opening.

[0016] The ring body is tapered from the bottom end to the top end, so that the ring body is tapered and corresponds to the inner wall of the pipe interface.

[0017] The beneficial effects of the utility model are:

[0018] The main technical features of the utility model are that the three-in-one water stop part is made in an integrated type by a ring body, a leak stop ring and a plurality of elastic arms, and is arranged in the pipe interface of the pipe joint, so that when the pipe joint is connected with the connecting pipe, the connecting pipe only needs to be inserted into the pipe interface of the pipe joint and the three-in-one water stop part, so that the ring body and the plurality of tooth pieces can be forced to bite the connecting pipe, so that the connecting pipe cannot be separated from the pipe joint.
