[0001] This utility model relates to the field of mechanical tee technology, and in particular to a quick-connect mechanical tee. Background Technology

[0002] A mechanical tee is a pipe fitting used for branch connections in pipelines. It mechanically creates a hole in the main pipe and connects to the branch pipe. It is commonly used in piping systems such as fire protection, water supply and drainage, and HVAC, and is especially suitable for situations where welding is not allowed or where construction space is limited.

[0003] However, in existing equipment, most mechanical tees use bolts to fix the upper and lower half of the bearing, which is cumbersome and affects the connection efficiency. Therefore, a mechanical tee for quick connection is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-connect mechanical tee.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-connect mechanical tee, comprising an upper half-plate and a lower half-plate, wherein a connecting seat is fixedly connected to one side of the upper half-plate, and a first threaded hole is provided on one side of the connecting seat, wherein a pressing structure is provided in the first threaded hole; a first connecting plate is fixedly connected to the opposite end of each upper half-plate, and an outer sleeve block is fixedly connected to one side of each first connecting plate, wherein a quick-connect structure is provided on each outer sleeve block; a second connecting plate is fixedly connected to the opposite end of each lower half-plate, and an inner sleeve block is fixedly connected to one side of each second connecting plate, wherein each inner sleeve block is adapted to a corresponding outer sleeve block, and a snap-fit ​​hole is provided on one side of each inner sleeve block.

[0006] As a further description of the above technical solution:

[0007] The quick-connect structure includes a fixed frame fixedly connected to one side of the outer casing block. A sliding rod is slidably connected through one side of the fixed frame. One end of the sliding rod is rotatably connected to a fork. One side of the fork is in contact with one side of the fixed frame.

[0008] As a further description of the above technical solution:

[0009] The other end of the sliding rod is fixedly connected to a snap-fit ​​post, which is slidably connected through to one side of the corresponding outer sleeve block, and each snap-fit ​​post is adapted to the corresponding snap-fit ​​hole.

[0010] As a further description of the above technical solution:

[0011] A spring is movably sleeved on the sliding rod. One end of the spring is fixedly connected to the inside side of the fixed frame, and the other end is fixedly connected to one side of the snap-fit ​​post.

[0012] As a further description of the above technical solution:

[0013] The extrusion structure includes a threaded rod threaded into a first threaded hole, and a nut is threaded onto the threaded rod.

[0014] As a further description of the above technical solution:

[0015] One end of the threaded rod is rotatably connected to an arc-shaped plate, and a rubber pad is fixedly connected to one side of the arc-shaped plate.

[0016] As a further description of the above technical solution:

[0017] A sealing gasket is fixedly connected to one side of the lower half tile, and a guide cylinder is fixedly connected to the other side. A second threaded hole is opened on one side of the guide cylinder, and a guide water pipe is threadedly connected to the second threaded hole.

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with existing technologies, this quick-connect mechanical tee, through the setting of a fixed frame, sliding rod, snap-fit ​​post, spring, and fork, places the upper half of the tee on one side of the main pipe. Then, by moving the fork, the fork moves the sliding rod, which in turn moves the snap-fit ​​post, causing the snap-fit ​​post to retract and compress the spring. Then, the lower half of the tee is placed on the other side of the main pipe, ensuring that the guide tube coincides with the hole opened in the main pipe. Then, the inner sleeve block snaps into the corresponding outer sleeve block. Then, by moving the fork again, the snap-fit ​​post snaps into the corresponding snap-fit ​​hole under the elasticity of the spring, connecting the upper and lower half of the tee. There is no need to fix the upper and lower half of the tee with bolts, making the operation convenient and improving the connection efficiency.

[0020] 2. Compared with existing technologies, this quick-connect mechanical tee uses a threaded rod, nut, arc plate, and rubber gasket. Rotating the threaded rod moves the arc plate, causing it to press the rubber gasket tightly against one side of the main pipe. Simultaneously, compression forces the sealing gasket to adhere tightly to the other side of the main pipe for rapid sealing. After sealing, rotating the nut tightens one side of the nut against the other side of the connector, locking the threaded rod and reducing the chance of a decrease in sealing effect due to loosening of the threaded rod.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 6This utility model provides a quick-connect mechanical tee: including an upper half-sleeve 1 and a lower half-sleeve 7. A connecting seat 5 is fixedly connected to one side of the upper half-sleeve 1. A first threaded hole is opened on one side of the connecting seat 5. A compression structure 6 is provided in the first threaded hole. A first connecting plate 2 is fixedly connected to the opposite end of the upper half-sleeve 1. An outer sleeve block 3 is fixedly connected to one side of each first connecting plate 2. A quick-connect structure 4 is provided on each outer sleeve block 3. A sealing gasket 10 is fixedly connected to one side of the lower half-sleeve 7. The sealing gasket 10 fits tightly against one side of the main pipe to reduce the probability of water leakage from the connection. A guide cylinder 11 is fixedly connected to the other side. A second threaded hole is opened on one side of the guide cylinder 11. A guide water pipe 12 is threadedly connected in the second threaded hole. A second connecting plate 8 is fixedly connected to the opposite end of the lower half-sleeve 7. An inner sleeve block 9 is fixedly connected to one side of each second connecting plate 8. Each inner sleeve block 9 is adapted to the corresponding outer sleeve block 3. A snap-fit ​​hole is opened on one side of each inner sleeve block 9.

[0031] The quick-connect structure 4 includes a fixed frame 401 fixedly connected to one side of the outer sleeve block 3. A sliding rod 402 is slidably connected through one side of the fixed frame 401. One end of the sliding rod 402 is rotatably connected to a fork 405. One side of the fork 405 is in contact with one side of the fixed frame 401. A locking post 403 is fixedly connected to the other end of the sliding rod 402. A spring 404 is movably sleeved on the sliding rod 402. One end of the spring 404 is fixedly connected to one side of the inside of the fixed frame 401, and the other end is fixedly connected to one side of the locking post 403. The locking post 403 is slidably connected through one side of the corresponding outer sleeve block 3. Each locking post 403 is adapted to a corresponding locking hole, allowing the upper... Half-tile 1 is placed on one side of the main pipe. Then, the fork 405 is moved. The fork 405 moves the sliding rod 402, which in turn moves the locking pin 403. This causes the locking pin 403 to retract and compress the spring 404. Then, the lower half-tile 7 is placed on the other side of the main pipe. The guide cylinder 11 is aligned with the hole in the main pipe. The inner sleeve 9 is then engaged with the corresponding outer sleeve 3. The fork 405 is moved again. Under the elasticity of the spring 404, the locking pin 403 is engaged with the corresponding locking hole, connecting the upper half-tile 1 and the lower half-tile 7. This eliminates the need to fix the upper half-tile 1 and the lower half-tile 7 with bolts, making the operation convenient and improving connection efficiency.

[0032] To achieve the extrusion purpose, the extrusion structure 6 includes a threaded rod 601 threadedly connected in a first threaded hole, a nut 602 threadedly connected to the threaded rod 601, an arc-shaped plate 603 rotatably connected to one end of the threaded rod 601, and a rubber pad 604 fixedly connected to one side of the arc-shaped plate 603. Rotating the threaded rod 601 causes the arc-shaped plate 603 to move, so that the arc-shaped plate 603 drives the rubber pad 604 to press tightly against one side of the main pipe. At the same time, through extrusion, the sealing gasket 10 is tightly adhered to the other side of the main pipe for rapid sealing. After sealing, the nut 602 is rotated so that one side of the nut 602 is tightly adhered to one side of the connecting seat 5, locking the threaded rod 601 and reducing the probability of a decrease in sealing effect due to loosening of the threaded rod 601.

[0033] Working principle: First, a hole is drilled in the main pipe. Then, the upper half-sleeve 1 is placed on one side of the main pipe. Next, the shift fork 405 is moved, which moves the sliding rod 402. The sliding rod 402 moves the locking pin 403, causing the locking pin 403 to retract and compress the spring 404. Then, the lower half-sleeve 7 is placed on the other side of the main pipe, ensuring that the guide cylinder 11 coincides with the hole drilled in the main pipe. Then, the inner sleeve block 9 is engaged into the corresponding outer sleeve block 3. Then, the shift fork 405 is moved again. Under the elasticity of the spring 404, the locking pin 403 is engaged into the corresponding locking hole, connecting the upper half-sleeve 1 and the lower half-sleeve 7. No bolts are needed to fix the upper half of the tile 1 and the lower half of the tile 7, making operation convenient and improving connection efficiency. After connection, rotate the threaded rod 601, which drives the arc plate 603 to move, so that the arc plate 603 drives the rubber pad 604 to press tightly against one side of the main pipe. At the same time, the sealing gasket 10 is pressed tightly against the other side of the main pipe for quick sealing. After sealing, rotate the nut 602, so that one side of the nut 602 is tightly against one side of the connecting seat 5, locking the threaded rod 601 and reducing the chance of the sealing effect decreasing due to the loosening of the threaded rod 601.
