Generally, the connector is equipped with gaskets, rubber, silicone and PTFE. It has good performance, high sealing and easy installation.

[0003] Current clamps are usually connected to each other using bolts. During long-term use, the bolted joints of the clamps may break due to factors such as vibration, stress concentration, and corrosion, thereby causing connection failure, safety accidents, or equipment failures. Accordingly, the present invention proposes a positioning error-proof clamp. Summary of the invention

The anti-drop assembly consists of a buckle mechanism and a rebound mechanism. The buckle mechanism includes four first slide grooves provided inside the first buckle plate. The rebound mechanism includes four connecting grooves formed on the second buckle plate; The sealing component is used to seal the connection between the clamp and the pipeline, and the sealing component consists of a secretion mechanism and a leak-proof mechanism.

[0006] Preferably, the insides of the four first slide grooves are fixedly connected with fixed columns, the bottoms of the four fixed columns are slidably connected with fixed plates slidably connected to the first slide grooves, the tops of the four fixed plates are fixedly connected to the four first slide grooves, the bottoms of the four fixed plates are fixedly connected with connecting columns slidably connected to the fixed columns, the four connecting columns are distributed in a circular shape and are equidistantly provided with four receiving grooves, the insides of the receiving grooves are fixedly connected with guide rods, the guide rods are slidably connected with a card block slidably connected to the receiving grooves, and a second spring is fixedly connected between the card block and the receiving groove.

[0007] Preferably, the bottoms of the four connecting grooves are fixedly connected to the third springs, the tops of the four third springs are fixedly connected to the bottom plate, and the inner walls of the four connecting grooves are provided with four slots that are distributed in a circular shape and are equidistantly formed.

[0008] Preferably, two threaded holes are formed on the first buckle plate and the second buckle plate, and a positioning frame is fixedly connected to the top of the first buckle plate and above the two threaded holes.

[0009] Preferably, the secretion mechanism includes a storage bin opened inside the first buckle plate, a through hole is opened at the bottom of the storage bin, a sealing membrane is fixedly connected inside the through hole, a second slide groove is opened inside the first buckle plate, a plurality of limit rods are fixedly connected inside the second slide groove, a pressure plate slidably connected to the limit rod and slidably connected to the second slide groove, a cone head is fixedly connected to the bottom of the pressure plate and located inside the through hole, a transverse axis is slidably connected to both ends of the pressure plate, a pull plate is fixedly connected to one end of the transverse axis and located inside the first slide groove, a fourth spring is fixedly connected between the pull plate and the pressure plate, and a ramp block is fixedly connected to the bottom of the pull plate.

[0010] Preferably, the leakage-proof mechanism includes a secretion groove opened on the first sealing ring and connected to the through hole, four tube columns connected to the secretion groove are fixedly connected to the bottom of the first sealing ring, filling grooves are opened on both sides of the second sealing ring, and four tube holes connected to the filling grooves are opened on the top of the second sealing ring.

[0011] Preferably, observation transparent plates are provided on both sides of the second sealing ring.

[0012] The present invention has the following beneficial effects: 1. By setting up the connection assembly, the upper and lower parts of the clamp can be fixedly connected by cooperating with the threaded holes of the first buckle plate and the second buckle plate, and a positioning frame is provided on the buckle plate, which helps to accurately position during installation, making the connection more stable, ensuring the reliability of the connection of the clamp to the pipeline, and effectively preventing problems such as loosening or falling off of the pipeline due to loose connection.

[0013] 2. By setting up an anti-drop assembly, when the bolt connection of the clamp breaks and fails, the block on the first buckle piece pops out under the action of the spring and cooperates with the slot on the second buckle piece. At the same time, the third spring in the rebound mechanism can play a buffering and auxiliary fixing role, so that the clamp can be fixed in time for emergency, avoiding the clamp from directly dispersing and falling off to cause safety accidents, thereby ensuring the integrity and safety of the pipeline system.

[0014] 3. By setting up a sealing component, the clamp connection can be sealed and protected through the synergistic effect of the secretion mechanism and the leak-proof mechanism. The air-hardening liquid material in the storage bin can pierce the sealing film through the pressing plate squeezing the cone head during the installation process, and then flow to the sealing part through the through hole, secretion groove, pipe column and other channels. At the same time, the filling groove and pipe hole of the second sealing ring can better accommodate and distribute the air-hardening liquid material, effectively fill the gap between the clamp and the pipeline, prevent liquid or gas leakage, and improve the sealing of the pipeline connection.

[0015] 4. By setting up an observation plate, the operator can observe the filling status of the air-hardening liquid material during use, timely discover possible sealing problems and make adjustments, which is conducive to improving installation efficiency and quality. At the same time, during subsequent pipeline maintenance and inspection, the sealing status can also be quickly checked through the observation plate to reduce maintenance costs and difficulty.

At this time, the first spring 10 pushes the fixing plate 9 to move downward, and the clamping block 15 on the connecting column 11 pops out under the action of the second spring 14 and is clamped into the clamping groove 19 on the inner wall of the connecting groove 16. At the same time, the third spring 17 is compressed, thereby achieving emergency fixation and preventing the clamp from directly dispersing and falling off. Furthermore, when the bolt connection of the clamp breaks and fails, the block 15 on the first clamp piece 1 can pop out under the action of the second spring 14 and cooperate with the slot 19 on the second clamp piece 2.

The cone head 26 pierces the sealing membrane 22, and the air-hardening liquid material in the storage bin 20 flows out through the through hole 21, and then flows into the secretion groove 31. At this time, the liquid in the secretion groove 31 continues to flow into the filling groove 33 through the pipe column 32, and seals the inside of the clamp after it solidifies.

[0026] Furthermore, when the sealing material flows from the storage bin 20 through the through hole 21, the secretion groove 31 and the pipe column 32 into the filling groove 33 of the second sealing ring 6, the filling condition of the sealing material can be observed through the observation plate 35 to ensure the sealing effect. After the sealing material flows into the filling groove 33, it can further diffuse through the pipe hole 34, so that the seal between the clamp and the pipeline is more perfect and leakage is effectively prevented.
