[0003] However, in practical applications, the existing pipe fitting connection devices have simple structural designs for their positioning components, which lack flexibility. When different types or sizes of pipe fittings need to be connected, it is often necessary to replace the entire device or make complex adjustments. This not only increases the difficulty and cost of operation, but also reduces the versatility and adaptability of the device.

[0004] Based on this, a pipe fitting connection device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-3 As shown, a pipe fitting connection device includes a base 1. Two guide rails 11 are symmetrically fixed on the front and rear sides of the upper end of the base 1. Two movable plates 2 are slidably installed on the left and right sides of the upper end of the two guide rails 11. A positioning element 3 and a first driving structure 4 connected to the positioning element 3 are provided on the upper end of the movable plate 2. Two second driving structures 5 are symmetrically installed on the left and right sides of the upper end of the base 1. A T-shaped opening 21 is opened at the end of the movable plate 2 near the second driving structure 5. Each second driving structure 5 is connected to a movable plate 2 through the T-shaped opening 21.

[0023] In this embodiment, the first driving structure 4 drives the positioning component 3 to position and fix the pipe. Then, the second driving structure 5 is activated, and the moving plate 2 moves on the guide rail 11 through the T-shaped opening 21, thereby changing the distance between the two moving plates 2 and thus connecting the pipe.

[0024] In an optional embodiment, the first driving structure 4 includes a U-shaped block 41 fixed to the upper end of the movable plate 2. The U-shaped block 41 is hinged to one end of the connecting block 42, and the other end of the connecting block 42 is hinged to the connecting plate 44. A pull rod 43 is fixed to the upper end of the connecting block 42, and the other end of the connecting plate 44 is hinged to an L-shaped block 45. The L-shaped block 45 is slidably mounted on a guide rail 47, which is fixed to the upper end of the movable plate 2. A fixing rod 48 is fixedly mounted to the other end of the L-shaped block 45. A limiting ring 481 and a limiting ring 482 are fixed to the outer wall of the fixing rod 48, and the limiting ring 481 and the limiting ring 482 are connected to the positioning member 3.

[0025] It should be noted that when positioning the pipe fittings is required, the operator can pull the pull rod 43. Since the pull rod 43 is fixedly connected to the upper end of the connecting block 42, and one end of the connecting block 42 is hinged to the U-shaped block 41, and the other end is hinged to the connecting plate 44, pulling the pull rod 43 will move the connecting block 42, which in turn will move the connecting plate 44. The other end of the connecting plate 44 is hinged to the L-shaped block 45, which is slidably mounted on the guide rail 47 fixed to the upper end of the moving plate 2. Therefore, under the action of the connecting plate 44, the L-shaped block 45 will slide along the guide rail 47.

[0026] A fixing rod 48 is fixedly installed at the other end of the L-shaped block 45. A limiting ring 481 and a limiting ring 482 are fixed to the outer wall of the fixing rod 48, and these limiting rings are connected to the positioning element 3. As the L-shaped block 45 slides, the fixing rod 48 moves accordingly, which in turn drives the positioning element 3 to move via the limiting rings 481 and 482. This causes the positioning element 3 to contact the pipe and apply a certain pressure, thereby achieving the positioning and fixing of the pipe.

[0027] This design makes the movement of positioning element 3 more stable and precise, effectively fixing the pipe in the right position and providing a reliable guarantee for subsequent pipe connection operations.

[0028] In an optional embodiment, the L-shaped block 45 slides on both sides with two guide blocks 46, and the two guide blocks 46 are fixed on the left and right sides of the upper end of the movable plate 2.

[0029] It should be noted that the presence of guide block 46 helps ensure that L-shaped block 45 moves in the predetermined direction and path, preventing it from swaying or deviating during the sliding process.

[0030] In an optional embodiment, the positioning element 3 includes a fixing block 31 fixed to the upper end of the movable plate 2 and a movable block 32 slidably mounted on the upper end of the guide rail 47. The movable block 32 has a T-shaped opening 35 at the end away from the fixing block 31. A limit ring 482 is provided inside the T-shaped opening 35, and a limit ring 481 is provided outside the T-shaped opening 35. The fixing block 31 and the movable block 32 each have a mounting groove 33 at their opposite ends. A mounting block 341 is slidably mounted inside the mounting groove 33 and is fixed on the positioning block 34.

[0031] It should be noted that when connecting different types or sizes of pipe fittings, it may be necessary to replace the positioning block 34 with one of different shapes or sizes. Since the positioning block 34 is slidably installed in the mounting groove 33 via the mounting block 341, the operator can easily remove the positioning block 34 from the mounting groove 33 and then install the appropriate positioning block 34, thus improving the versatility and adaptability of the device.

[0032] In an optional embodiment, the mounting groove 33 and the mounting block 341 have a T-shaped cross-section.

[0033] It should be noted that the T-shaped structure not only helps the mounting block 341 to remain stable inside the mounting groove 33 and not easily fall off, but also does not affect the installation and disassembly operations between the mounting block 341 and the mounting groove 33, thereby improving work efficiency, reducing maintenance costs, and enabling the positioning component 3 to be quickly adapted and adjusted according to different pipe connection requirements.

[0034] In an optional embodiment, the second driving structure 5 includes a fixed base 51 fixed to the upper end of the base 1. A second fixed block 52 is fixed to the upper end of the fixed base 51. A driving block 53 is hinged inside the second fixed block 52. A second pull rod 54 is fixed on the driving block 53. A driving groove 531 is opened at the lower end of the driving block 53. The driving groove 531 is hinged to one end of a second connecting plate 55. The other end of the second connecting plate 55 is hinged to a second fixed rod 56. A through opening 521 is opened on the second fixed block 52. The inner wall of the through opening 521 is slidably connected to the outer wall of the second fixed rod 56. A screw rod 57 is threadedly connected to the end of the second fixed rod 56 away from the second fixed block 52. A nut 58 and a nut 59 are threadedly connected to the screw rod 57. The nut 59 is located inside the first T-shaped opening 21, and the nut 58 is located on the outer wall of the first T-shaped opening 21.

[0035] It should be noted that the threaded connection between screw 57 and nuts 58 and 59 allows for precise control of the moving distance of the movable plate 2. Operators can adjust the pulling amplitude of lever 54 to precisely change the distance between the two movable plates 2, meeting the requirements of different pipe fitting connections and improving the accuracy and quality of the pipe fitting connection.

[0036] In an optional embodiment, a rubber pad is installed on the second pull rod 54, and the outer surface of the rubber pad is provided with anti-slip texture.

[0037] It should be noted that the rubber pad has good flexibility and elasticity, which can effectively cushion the pressure between the hand and the lever 54, reducing the pressure on the hand and making it easier and more comfortable for the operator to pull the lever 54. This reduces operator fatigue and improves work efficiency. The anti-slip texture on the outer surface of the rubber pad further enhances the convenience and safety of operation.

[0038] The above embodiment discloses a pipe fitting connection device, in which the operator pulls the pull rod 43 in the first drive structure 4. Since the pull rod 43 is fixedly connected to the upper end of the connecting block 42, and one end of the connecting block 42 is hinged to the U-shaped block 41 fixed to the upper end of the moving plate 2, and the other end is hinged to the connecting plate 44, pulling the pull rod 43 will drive the connecting block 42 to move, thereby driving the connecting plate 44 to move.

[0039] The other end of the connecting plate 44 is hinged to the L-shaped block 45, which is slidably mounted on the guide rail 47 fixed on the upper end of the movable plate 2. Under the drive of the connecting plate 44, the L-shaped block 45 will slide along the guide rail 47.

[0040] As the L-shaped block 45 slides, the fixing rod 48 moves accordingly, and then the moving block 32 in the positioning component 3 slides on the guide rail 47 through the limiting ring 481 and the limiting ring 482. This changes the distance between the moving block 32 and the fixing block 31 fixed at the upper end of the moving plate 2, thereby allowing the positioning block 34 to contact the pipe and apply a certain pressure to achieve the positioning and fixing of the pipe.

[0041] After the pipe fitting is positioned, the operator pulls the second pull rod 54 in the second drive structure 5. Pulling the second pull rod 54 will cause the drive block 53 to rotate around the hinge point inside the second fixed block 52 at the upper end of the fixed seat 51 fixed on the upper end of the base 1.

[0042] As the drive block 53 moves, it drives the connecting plate 55 to move. The other end of the connecting plate 55 is hinged to the fixing rod 56, thus transmitting power to the fixing rod 56, causing it to slide against the inner wall of the through-hole 521 on the fixing block 52. When the fixing rod 56 moves, it drives the screw 57 to move. Due to the restraining effect of the nut 59 within the T-shaped opening 21 and the engagement of the nut 58 on the outer wall of the T-shaped opening 21, the movement of the screw 57 is converted into a pushing and pulling force on the moving plate 2, thereby causing the moving plate 2 to slide on the two guide rails 11 symmetrically fixed on the front and rear sides of the upper end of the base 1, thus achieving the connection of the pipe fitting.

[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
