Description

Technical Field

[0001] This utility model relates to the field of fire protection pipe fittings technology, and in particular to a quick-connect clamp for fire protection pipe fittings. Background Technology

[0002] Fire protection pipe fittings refer to pipeline materials used in fire protection to connect fire protection equipment and materials, and to transport fire-fighting water, gas, or other media. Pipes typically require clamps for connection during jointing. However, existing fire protection pipe fitting connection clamp structures, while providing positioning and fixation, cannot adequately guarantee the external protective sealing performance of the pipeline. To address this, patent publication number CN215000065U discloses "A Connection Clamp Structure Based on Fire Protection Pipe Fittings." This solution improves the sealing performance of fire protection pipe fittings by installing an internal fixing sealing ring inside the fixed semi-circular clamp. The fixed semi-circular clamp and the second semi-circular clamp are installed and fixed by installing fixing bolts and fixing limit nuts on both sides. The opposing arrangement of the fixing bolts ensures a tighter installation, thus solving the problem that existing fire protection pipe fitting connection clamp structures cannot adequately guarantee the external protective sealing performance of the pipeline while providing positioning and fixation.

[0003] However, in this solution, the installation of the fixed semicircular clamp and the second semicircular clamp is cumbersome and affects the installation efficiency by fixing bolts. Therefore, a quick connection clamp for fire protection pipe fittings is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick-connect clamp for fire-fighting pipe fittings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-connect clamp for fire-fighting pipe fittings, comprising a fixed semi-circular clamp and a second semi-circular clamp, wherein both the fixed semi-circular clamp and the second semi-circular clamp are internally fitted with an inner fixing sealing ring, both sides of the second semi-circular clamp are fixedly connected with side fixing edges, both sides of the fixed semi-circular clamp are fixedly connected with connecting fixing edges, one side of each of the two connecting fixing edges is fixedly connected with a connecting seat, one side of each connecting seat is fixedly connected with a snap-fit ​​seat, one side of each snap-fit ​​seat is provided with a snap-fit ​​hole, and each connecting seat is provided with a connecting structure;

[0006] The connection structure includes a rotating frame rotatably connected to the connecting seat. The rotating frame has a first moving groove and a second moving groove on its opposite sides. A sliding column is fixedly connected in each of the first moving grooves. Rotating the rotating frame causes it to cover the fixed side.

[0007] As a further description of the above technical solution:

[0008] Two second movable slots are slidably connected to movable frames. The opposite sides of the movable frames are rotatably connected to a rotating column. A first rotating block is fixedly connected to the rotating column. A rotating slot is opened on one side of the first rotating block. A second rotating block is rotatably connected in the rotating slot. The rotating column drives the first rotating block to rotate. The first rotating block drives the second rotating block to move through the rotating slot.

[0009] As a further description of the above technical solution:

[0010] Each of the sliding columns is slidably connected to a moving block. Two moving blocks are fixedly connected to a pressing block on opposite sides. One side of the pressing block is fixedly connected to an anti-slip pad, and the other side is fixedly connected to two fixing plates. Two fixing plates are fixedly connected to a rotating rod on opposite sides. The rotating rod is rotatably connected to the other end of a second rotating block. The other end of the second rotating block drives the two fixing plates to move through the rotating rod. The fixing plates drive the pressing block to move, and the pressing block drives the two moving blocks to slide on the corresponding sliding columns, so that the anti-slip pad on one side of the pressing block is pressed against the corresponding side fixing edge.

[0011] As a further description of the above technical solution:

[0012] The rotating column is fixedly connected to a toggle frame at opposite ends. A sliding rod is slidably connected to one side of the toggle frame. A locking post is fixedly connected to one end of the sliding rod. The locking post is adapted to the locking hole. Pulling the sliding rod causes the locking post to retract.

[0014] A return spring is fitted on the sliding rod. One end of the return spring is fixedly connected to the inside side of the toggle frame, and the other end is fixedly connected to one side of the locking post. Under the elastic reset of the return spring, the locking post is pushed into the corresponding locking hole, and the toggle frame is mechanically locked.

[0015] As a further description of the above technical solution:

[0016] Two limiting rods are fixedly connected to one side of the movable frame. Each limiting rod is slidably connected to one side of the rotating frame. Rotating the threaded rod causes the movable frame to move within the second movable groove. The movable frame moves the two limiting rods on one side of the rotating frame, shortening the distance between the movable frame and the fixed side, thus improving the extrusion effect.

[0017] As a further description of the above technical solution:

[0018] A threaded rod is threaded through one side of the rotating frame. One end of the threaded rod is rotatably connected to one side of the moving frame. A fastening nut is threaded onto the threaded rod. Rotating the fastening nut causes one side of the fastening nut to fit tightly against one side of the rotating frame, locking the threaded rod and preventing it from loosening.

[0031] 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.

[0032] Reference Figures 1 to 7 This utility model provides a quick-connect clamp for fire-fighting pipe fittings: it includes a fixed semi-circular clamp 1 and a second semi-circular clamp 2. Both the fixed semi-circular clamp 1 and the second semi-circular clamp 2 are equipped with an inner fixing sealing ring 3 to improve the sealing performance. The second semi-circular clamp 2 is fixedly connected to two side fixing edges 4 on both sides. The fixed semi-circular clamp 1 is fixedly connected to two side fixing edges 5 on both sides. A connecting seat 6 is fixedly connected to one side of each connecting seat 6. A snap-fit ​​seat 7 is fixedly connected to one side of each snap-fit ​​seat 7. A snap-fit ​​hole is opened on one side of each snap-fit ​​seat 7 to snap-fit ​​and position the snap-fit ​​post 814. Each connecting seat 6 is equipped with a connecting structure 8.

[0033] To achieve rapid connection, the connection structure 8 includes a rotating frame 801 rotatably connected to the connecting seat 6. Each of the rotating frame 801 has a first moving groove and a second moving groove 803 on opposite sides. A sliding column 802 is fixedly connected to each of the first moving grooves. A moving frame 804 is slidably connected to both of the two second moving grooves 803. A rotating column 805 is rotatably connected through opposite sides of the moving frame 804. A toggle frame 812 is fixedly connected to opposite ends of the rotating column 805. A first rotating block 806 is fixedly connected to the rotating column 805. A rotating groove is formed on one side of the first rotating block 806, and a second rotating block 807 is rotatably connected to the groove. A moving block 809 is slidably connected to each sliding column 802. A pressing block 808 is fixedly connected to opposite sides of the two moving blocks 809. An anti-slip pad is fixedly connected to one side of the pressing block 808, and two fixing plates 8 are fixedly connected to the other side. 10. Two fixed plates 810 are fixedly connected to a rotating rod 811 on opposite sides. The rotating rod 811 is rotatably connected to the other end of the second rotating block 807. The actuating frame 812 is moved towards the direction of the fixed semicircular clamp 1, so that the actuating frame 812 is flush with the rotating frame 801. One end of the actuating frame 812 drives the rotating column 805 to rotate on the moving frame 804. The rotating column 805 drives the first rotating block 806 to rotate. The first rotating block 806 drives the second rotating block 807 to move through the rotating groove. The other end of the second rotating block 807 drives the two fixed plates 810 to move through the rotating rod 811. The fixed plates 810 drive the pressing block 808 to move. The pressing block 808 drives the two moving blocks 809 to slide on the corresponding sliding column 802, so that the anti-slip pad on one side of the pressing block 808 is pressed against one side of the corresponding side fixed edge 4, so that the second semicircular clamp 2 can be quickly connected without the need for bolt installation, thus improving installation efficiency.

[0034] To achieve the locking purpose, a sliding rod 813 is slidably connected through one side of the toggle frame 812. One end of the sliding rod 813 is fixedly connected to a locking post 814. A return spring 815 is sleeved on the sliding rod 813. One end of the return spring 815 is fixedly connected to one side of the inside of the toggle frame 812, and the other end is fixedly connected to one side of the locking post 814. The locking post 814 is adapted to the locking hole. When the sliding rod 813 is released, under the elastic reset of the return spring 815, the locking post 814 is pushed into the corresponding locking hole, and the toggle frame 812 is mechanically locked, improving the stability of the toggle frame 812.

[0035] To achieve the adjustment, two limiting rods 816 are fixedly connected to one side of the moving frame 804. Each limiting rod 816 is slidably connected to one side of the rotating frame 801. A threaded rod 817 is threadedly connected to one side of the rotating frame 801. One end of the threaded rod 817 is rotatably connected to one side of the moving frame 804. A fastening nut 818 is threaded onto the threaded rod 817. When the pressing block 808 presses the side fixed edge 4 loosely, the threaded rod 817 is rotated during pressing. The threaded rod 817 drives the moving frame 804 to move within the second moving groove 803. The moving frame 804 drives the two limiting rods 816 on one side of the rotating frame 801, shortening the distance between the moving frame 804 and the side fixed edge 4, thus improving the pressing effect. After adjustment, the fastening nut 818 is rotated so that one side of the fastening nut 818 fits tightly against one side of the rotating frame 801, locking the threaded rod 817 and preventing it from loosening.

[0036] Working principle: The fixed semi-circular clamp 1 and the second semi-circular clamp 2 are clamped at the connection of the two pipes. Then, the rotating frame 801 is rotated so that it covers the side fixed edge 4. Next, the sliding rod 813 is pulled, causing the locking post 814 to retract and compress the return spring 815. Then, the actuating frame 812 is moved towards the fixed semi-circular clamp 1 so that it is flush with the rotating frame 801. One end of the actuating frame 812 drives the rotating post 805 to rotate on the moving frame 804. The rotating post 805 drives the first rotating block 806 to rotate. The first rotating block 806 drives the second rotating block 807 to move through the rotating groove. The other end of the second rotating block 807 drives the two fixed plates 810 to move through the rotating rod 811. The fixed plates 810 drive the pressing block 808 to move. The pressing block 808 drives the two moving blocks 809 to slide on the corresponding sliding post 802, thus preventing slippage on one side of the pressing block 808. The pad is pressed against one side of the corresponding side fixed edge 4 to quickly connect the second semi-circular clamp 2 without the need for bolt installation, thus improving installation efficiency. Then, the sliding rod 813 is released, and under the elastic reset of the return spring 815, the locking post 814 is pushed into the corresponding locking hole. The actuating frame 812 is mechanically locked to improve its stability. When the pressing block 808 is pressing the side fixed edge 4 loosely, the threaded rod 817 is rotated between pressing operations. The threaded rod 817 drives the moving frame 804 to move within the second moving groove 803. The moving frame 804 drives the two limit rods 816 on one side of the rotating frame 801 to shorten the distance between the moving frame 804 and the side fixed edge 4, thus improving the pressing effect. After adjustment, the fastening nut 818 is rotated to make one side of the fastening nut 818 tightly fit against one side of the rotating frame 801, locking the threaded rod 817 to prevent it from loosening.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
