[0002] Grooved mechanical tee connectors, as an important component of piping systems, are mainly used to achieve branch connections in pipelines. In piping systems of fire protection, water supply and drainage, and petrochemical industries, mechanical tee connectors have been widely used due to their flexibility and convenience. They achieve pipeline branching or merging by directly drilling holes in the main pipeline and connecting branch pipes, thus meeting the needs of complex pipeline layouts.

[0003] Traditional grooved mechanical tee connectors still have some shortcomings during installation. In particular, their locking structure typically uses two arc-shaped clamps connected by bolts. During installation, workers need to simultaneously join the two arc-shaped clamps together and install the bolts, a cumbersome process requiring certain professional skills and experience. Therefore, a quick-installation grooved mechanical tee connector is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a quick-installation grooved mechanical tee connector to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a quick-installation grooved mechanical tee connector, including a first arc-shaped clamp and a second arc-shaped clamp corresponding vertically. A connecting pipe is fixedly connected to the outer surface of the second arc-shaped clamp, and a connecting groove is formed on the outer surface of the connecting pipe. First locking plates are fixedly connected to both ends of the first arc-shaped clamp, and second locking plates are fixedly connected to both ends of the second arc-shaped clamp. The two first locking plates correspond vertically to the two second locking plates, and a bolt is rotatably connected to one side of each first locking plate. The bottom of the two second locking plates... Each surface has a limiting groove, and a hexagonal nut is provided inside each limiting groove. Two hexagonal nuts are threadedly connected to two bolts respectively. Each end of the first arc-shaped clamp has a slot and two grooves. The insertion port is located between the two grooves. An assembly plate is inserted into the slot. Both assembly plates are fixedly connected to the second arc-shaped clamp. A spring is fixedly connected to the inner wall of each groove. A connecting rod is fixedly connected to one end of the spring. The connecting rod is slidably connected to the second arc-shaped clamp. An arc-shaped locking plate is fixedly connected to the end of the connecting rod away from the spring. The arc-shaped locking plate is engaged with the assembly plate.

[0007] Preferably, as described in any of the above schemes, the assembly plate has slots on both the left and right sides, and the arc-shaped card plate is engaged with the assembly plate through the slots.

[0008] Preferably, in any of the above solutions, a positioning plate is fixedly connected to the bottom surface of the first locking plate, and a positioning groove is provided through the top surface of the second locking plate, wherein the positioning plate is slidably connected to the second locking plate through the positioning groove.

[0009] Preferably, in any of the above schemes, the inner wall of the limiting groove is fixedly connected with a plurality of V-shaped limiting supports arranged in a circular array, and the six corners of the hexagonal nut are slidably connected to the V-shaped limiting supports.

[0010] Preferably, in any of the above embodiments, a guide rod is fixedly connected to the end of the connecting rod away from the arc-shaped plate, and a guide sleeve is fixedly connected to the inner wall of the groove.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] When installing a tee connector, the first arc-shaped clamp is fitted onto the pipe. Then, the second arc-shaped clamp is removed, and the two assembly plates are aligned with the two slots. The second arc-shaped clamp is then pushed to insert the two assembly plates into the slots. As the assembly plates are gradually inserted, the rounded corners of the assembly plates will slide against the arc-shaped parts of the two arc-shaped clamps until the assembly plates are fully inserted into the slots. The arc-shaped clamps will then be inserted into the slots, locking the assembly plates in the slots. This completes the initial assembly of the first and second arc-shaped clamps, eliminating the need for workers to tighten bolts while assembling the clamps. This reduces the assembly difficulty of the tee connector and enables rapid installation. Attached Figure Description

[0029] 1): When installing the tee connector, the first arc clamp 1 can be fitted onto the pipe, and then the second arc clamp 2 can be removed and the two assembly plates 12 aligned with the two slots 10.

[0030] 2): Push the second arc-shaped clamp 2 to insert the two assembly plates 12 into the two slots 10. As the assembly plates 12 are gradually inserted, the rounded corners of the assembly plates 12 will slide against the arc-shaped parts of the two arc-shaped clamps 15 until the assembly plates 12 are fully inserted into the slots 10. Then the arc-shaped clamps 15 will be inserted into the slots 16, which can lock the assembly plates 12 in the slots 10.

[0031] 3): This enables the initial assembly of the first arc-shaped clamp 1 and the second arc-shaped clamp 2, eliminating the need for workers to lock the bolts while assembling the clamps, thus reducing the assembly difficulty of the tee connector.

[0032] In summary, this quick-installation grooved mechanical tee connector allows for easy installation. First, the first arc-shaped clamp 1 is fitted onto the pipe. Then, the second arc-shaped clamp 2 is removed, and the two assembly plates 12 are aligned with the two slots 10. Pushing the second arc-shaped clamp 2 inserts the two assembly plates 12 into the slots 10. As the assembly plates 12 are gradually inserted, their rounded corners slide against the arc-shaped portions of the two arc-shaped clamps 15 until they are fully inserted into the slots 10. Then, the arc-shaped clamps 15 are inserted into the slots 16, locking the assembly plates 12 in the slots 10. This achieves the initial assembly of the first arc-shaped clamp 1 and the second arc-shaped clamp 2, eliminating the need for workers to tighten bolts while assembling the clamps. This reduces the assembly difficulty of the tee connector and enables rapid installation.
