Description

Technical Field

[0001] This utility model belongs to the field of pipe connection clip technology, and particularly relates to quick clips. Background Technology

[0002] In centralized material supply systems, the connection between pipes is of paramount importance. Using clamp connection technology to connect pipes has become the preferred technology for connecting liquid and gas pipelines. The application of clamp connection technology simplifies, speeds up and facilitates complex pipeline connection procedures, representing a significant step forward in pipeline connection technology.

[0003] Traditional connection methods use common quick clamps to connect two pipes. However, in actual use, it has been found that air leakage can occur at the clamp connection, and the mating of the male and female clamps is not very convenient during installation, which greatly increases the pressure on the pipe fan and the difficulty of operation for installers.

[0004] Therefore, we propose a quick-release buckle to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor sealing and unstable connection of pipes in the prior art, and to propose a quick-release buckle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The quick-release buckle includes an upper clamp, the bottom of which is hinged to a lower clamp. Both sides of the upper and lower clamps are fixedly connected to stabilizing arc-shaped plates, with their adjacent sides in contact. A first pipe and a second pipe are provided below the upper clamp and above the lower clamp. The adjacent sides of the two stabilizing arc-shaped plates respectively contact the outer surfaces of the first and second pipes. The inner wall of each stabilizing arc-shaped plate is fixedly connected to equally spaced sealing plates, with their adjacent sides in contact. The outer surfaces of both the first and second pipes have equally spaced sealing grooves, and each sealing plate is snapped into the interior of a sealing groove.

[0008] Preferably, the right end of the first pipe and the left end of the second pipe are respectively fixedly connected to a female clamp and a female clamp, and the female clamp and the female clamp are both engaged inside the upper clamp and the lower clamp, respectively.

[0009] Preferably, a sealing ring is provided on the right side of the female clamp and the left side of the female clamp, and the outer surface of the sealing ring is in contact with the inner top wall of the upper clamp and the inner bottom wall of the lower clamp.

[0010] Preferably, both the outer surfaces of the upper and lower clamps are fixedly connected with tightening blocks, the two tightening blocks are in contact with each other on their closest sides, and the two tightening blocks are connected with a fastening bolt through their common internal thread. The bottom end of the fastening bolt passes through the two tightening blocks in sequence and extends to the bottom of the tightening blocks.

[0011] Preferably, the outer surface of the fastening bolt is threaded with a positioning nut, and the upper surface of the positioning nut is fixedly connected to the bottom surface of one of the tightening blocks.

[0012] Preferably, the outer surfaces of the first pipe and the second pipe are both fixedly connected with retaining rings, and the side of the two retaining rings that are far apart from each other and the outer surfaces of the two retaining rings respectively contact the inner walls of the two stable arc-shaped plates.

[0013] Preferably, each of the two stable arc-shaped plates has an extension plate fixedly connected to its opposite side, the two extension plates have their opposite sides in contact, and the opposite sides of the two extension plates are in contact with the outer surfaces of the first pipe and the second pipe, respectively.

[0014] In summary, the technical effects and advantages of this utility model are as follows: By providing an upper clamp, a lower clamp, a stabilizing arc plate, a first pipe, and a second pipe, the upper and lower clamps can form a retractable structure to tighten the female clamp, female clamp, and sealing ring at the connection between the first and second pipes, thus facilitating the connection between the first and second pipes. Furthermore, the extended stabilizing arc plate improves the connection stability between the first and second pipes. The cooperation of the sealing plate and the sealing groove allows multiple sealing plates to be inserted into multiple sealing grooves to form a rectangular seal, thereby sealing the contact point between the stabilizing arc plate and the first and second pipes. This enhances the sealing effect of the quick-release connection, enabling a stable and sealed connection of the pipes using this quick-release mechanism. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 The quick-release buckle includes an upper clamp 3, with a lower clamp 4 movably hinged to the bottom surface of the upper clamp 3. Tightening blocks 5 are fixedly connected to the outer surfaces of both the upper clamp 3 and the lower clamp 4. The two tightening blocks 5 are in contact on their adjacent sides. A fastening bolt 13 is threaded into the interior of both tightening blocks 5. The bottom end of the fastening bolt 13 passes through both tightening blocks 5 and extends below them. By manually twisting the fastening bolt 13, the two tightening blocks 5 on the outer surfaces of the upper clamp 3 and the lower clamp 4 are brought closer together and tightened, thus enabling the connection of the pipe using the cooperation of the upper clamp 3 and the lower clamp 4.

[0022] The outer surface of the fastening bolt 13 is threaded with a positioning nut 14. The upper surface of the positioning nut 14 is fixedly connected to the bottom surface of one of the tightening blocks 5. The fastening bolt 13 is manually twisted to cooperate with the fixed positioning nut 14, so as to facilitate a stable connection of the fastening bolt 13 in the two tightening blocks 5.

[0023] Stable arc-shaped plates 6 are fixedly connected to both sides of the upper clamp 3 and both sides of the lower clamp 4. The two stable arc-shaped plates 6 are in contact with each other on their closest sides. A first pipe 1 and a second pipe 2 are provided below the upper clamp 3 and above the lower clamp 4. The two stable arc-shaped plates 6 are in contact with the outer surfaces of the first pipe 1 and the second pipe 2, respectively. A retaining ring 12 is fixedly connected to the outer surfaces of the first pipe 1 and the second pipe 2. The two retaining rings 12 are in contact with the inner walls of the two stable arc-shaped plates 6 on their furthest sides and the outer surfaces of the two retaining rings 12, respectively. By fixing the retaining rings 12 to the outer surfaces of the first pipe 1 and the second pipe 2, the stable arc-shaped plates 6 can be easily limited, thereby enabling the stable arc-shaped plates 6 to be stably installed on the outer surfaces of the first pipe 1 and the second pipe 2.

[0024] The right end of the first pipe 1 and the left end of the second pipe 2 are respectively fixedly connected to a female clamp 8 and a female clamp 9. The female clamp 8 and the female clamp 9 are both clamped inside the upper clamp 3 and the lower clamp 4. The female clamp 8 and the female clamp 9 are welded to the right end of the first pipe 1 and the left end of the second pipe 2 by manual welding, so that the first pipe 1 and the second pipe 2 can be easily connected.

[0025] A sealing ring 10 is provided on the right side of the female clamp 8 and the left side of the female clamp 9. The outer surface of the sealing ring 10 contacts the inner top wall of the upper clamp 3 and the inner bottom wall of the lower clamp 4. By using the sealing ring 10, which is set between the female clamp 8 and the female clamp 9, a sealing installation can be performed between the female clamp 8 and the female clamp 9.

[0026] Each stable arc plate 6 has a sealing plate 15 fixedly connected to its inner wall at equal intervals. The sides of two sealing plates 15 that are close to each other are in contact with each other. The outer surfaces of the first pipe 1 and the second pipe 2 are provided with sealing grooves 11 that are arranged at equal intervals. Each sealing plate 15 is snapped into the inside of the sealing groove 11. The sides of two stable arc plates 6 that are far from each other are fixedly connected to extension plates 7. The sides of two extension plates 7 that are close to each other are in contact with each other. The sides of two extension plates 7 that are close to each other are in contact with the outer surfaces of the first pipe 1 and the second pipe 2, respectively. By using extension plates 7, the connection between the stable arc plate 6 and the first pipe 1 and the second pipe 2 can be extended, thereby further improving the sealing performance of the quick-clamp connection between the first pipe 1 and the second pipe 2.

[0027] The working principle of this utility model is as follows: When using this quick-release buckle to achieve a stable sealing connection between the two ends of the first pipe 1 and the second pipe 2, firstly, the female clamp 8 and the female clamp 9 are manually welded to one end of the connection between the first pipe 1 and the second pipe 2, and a sealing ring 10 is set between the female clamp 8 and the female clamp 9 to enable a buffer sealing connection between the first pipe 1 and the second pipe 2 through the female clamp 8, the female clamp 9, and the sealing ring 10. Then, the upper clamp 3 and the lower clamp 4 are manually installed and snapped onto the outside of the female clamp 8, the female clamp 9, and the sealing ring 10. At the same time, the stabilizing arc plate 6 and the extension plate 7 fixed on both sides of the upper clamp 3 and the lower clamp 4 are snapped onto the first... On the outside of pipe 1 and pipe 2, multiple sealing plates 15 fixed to the inner wall of the stabilizing arc plate 6 are engaged with multiple sealing grooves 11 opened on the outside of pipe 1 and pipe 2. The sealing grooves 11 and sealing plates 15 can form a rectangular seal, thereby sealing the connection between the stabilizing arc plate 6 and pipe 1 and pipe 2. This allows for a stable and sealed connection between the two ends of pipe 1 and pipe 2. Finally, by manually twisting and tightening the bolts 13 and the positioning nuts 14, the two tightening blocks 5 fixed to the outside of the upper clamp 3 and lower clamp 4 can be brought closer and tightened, thereby stably sealing the connection between pipe 1 and pipe 2.
