Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a quick-opening clamp structure for a micro reactor. Background Technology

[0002] Microreactors are widely used in small-scale experiments and production processes in many fields such as chemical engineering, materials synthesis, and biopharmaceuticals.

[0003] Traditional microreactor connection structures are often complex, typically using multiple bolts, nuts, and gaskets for sealing and securing. This connection method has several drawbacks in practical operation. For example, installation and disassembly are time-consuming and labor-intensive, requiring operators to tighten or loosen multiple bolts one by one, resulting in low work efficiency and high labor intensity. Furthermore, bolts are susceptible to loosening after prolonged use due to vibration, temperature changes, and media corrosion, leading to a decline in the reactor's sealing performance and leakage. This not only wastes materials but also poses potential safety hazards, such as leaks of toxic or harmful gases threatening the health of operators, or leaks of flammable materials causing serious accidents like fires or explosions. Utility Model Content

[0004] The purpose of this invention is to provide a quick-opening clamp structure for a micro reactor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution, which includes a quick-clamp assembly, wherein the vessel body and the vessel lid are connected by the quick-clamp assembly, and the quick-clamp assembly is provided with an anti-loosening component and a fixing component.

[0006] As a preferred embodiment of this utility model, the quick-clamp assembly includes a left half-ring shell and a right half-ring shell. A fixing block is provided at the tail of the left half-ring shell, and a first rotating shaft is provided at the tail of the right half-ring shell. The first rotating shaft is movably mounted on the fixing block. A fixing plate is provided at the front of the right half-ring shell, and a through hole is provided on the fixing plate. An mounting block is provided at the front of the left half-ring shell. The anti-loosening component and the fixing component are both provided on the mounting block.

[0007] As a preferred embodiment of this utility model, the anti-loosening component includes a pull rod, which is movably disposed within a mounting block. A mounting cylinder is provided on the side of the mounting block, and one side of the pull rod is located within the mounting cylinder. A compression disc is provided on the pull rod, and the compression disc is disposed within the mounting cylinder. A compression spring is provided within the mounting cylinder, and the compression spring is sleeved on the outside of the pull rod and abuts against the top surface of the mounting cylinder and the compression disc. A ratchet is provided at the top of the side of the pull rod located within the mounting block, and a gripper is provided at the other end of the pull rod.

[0008] As a preferred embodiment of this utility model, the top and bottom of the mounting block are symmetrically provided with second rotating shafts, the fixing component includes a U-shaped movable part, the U-shaped movable part is movably disposed on the two second rotating shafts, the tail of the U-shaped movable part is provided with an internal threaded cylinder, the internal threaded cylinder is provided with a screw, the top of the screw is provided with an end face ratchet, and the tail of the screw is provided with a knob.

[0009] As a preferred embodiment of this utility model, a connector is provided at the top of the U-shaped movable part, and an inverted L-shaped limiting rod is movably provided on the connector.

[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0011] 1. This utility model makes the connection and disassembly of the vessel body and the vessel cover extremely simple and quick through the design of the quick-clamp assembly. The left half of the ring shell and the right half of the ring shell are connected by the first rotating shaft. The operator only needs to manually rotate the right half of the ring shell to open and close the ring. Compared with the traditional complicated connection method, it greatly saves operation time and labor costs. Especially in experimental or production scenarios where the reactor needs to be opened and closed frequently, it can significantly improve work efficiency.

[0012] 2. This utility model provides a solid guarantee for the connection stability of the reactor through the anti-loosening component. The compression spring always applies pressure to the compression plate, thereby making the end face ratchet on the pull rod closely cooperate with the end face ratchet of the fixing component. This structure effectively prevents the screw from rotating in the opposite direction due to vibration, pressure changes or other external factors during operation, ensuring that the clamping force of the quick clamping component on the reactor body and lid is stable and long-lasting, reducing the risk of leakage or other safety accidents caused by loose connection, and improving the safety and reliability of reactor operation.

[0013] 3. The fixing component in this utility model not only relies on the threaded engagement between the screw and the internal threaded cylinder to achieve the basic fixing function, but also adds an inverted L-shaped limiting rod as an additional protective measure. When the knob is tightened, rotating the inverted L-shaped limiting rod will position its baffle behind the knob. Even in the extreme case where the anti-loosening mechanism of the end face ratchet and end face ratchet fails, the inverted L-shaped limiting rod can effectively prevent the knob from accidentally reversing, providing double insurance for the connection stability of the reactor, further enhancing the reliability of the entire device under complex working conditions, and reducing downtime and maintenance costs caused by equipment failure.

[0024] 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 specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figures 1-9As shown, the present invention proposes a quick-opening clamp structure for a miniature reactor, which mainly includes a quick-clamp assembly 3 as a key part connecting the reactor body 1 and the reactor cover 2. It is mainly composed of a left half-ring shell 30 and a right half-ring shell 32. The fixing block 31 at the tail of the left half-ring shell 30 is connected to the first rotating shaft 33 at the tail of the right half-ring shell 32, so that the right half-ring shell 32 can rotate flexibly relative to the left half-ring shell 30 around the first rotating shaft 33, thereby realizing the opening and closing action of the ring to adapt to the connection and disassembly operation of the reactor body 1 and the reactor cover 2. A fixing plate 36 is provided at the front of the right half-ring shell 32, and the through hole 37 on it corresponds to the position of the mounting block 34 at the front of the left half-ring shell 30, providing a basic structure for the subsequent installation of the fixing assembly 5.

[0026] The anti-loosening component 4 is located inside the mounting block 34. The pull rod 41 passes through it and can move freely within the mounting block 34. The part of the pull rod 41 inside the mounting cylinder 40 is connected to the compression plate 42. The compression spring 43 is sleeved on the outside of the pull rod 41 and placed inside the mounting cylinder 40. Its two ends abut against the top surface inside the mounting cylinder 40 and the compression plate 42, respectively. The elastic force of the spring provides continuous pressure support for the anti-loosening function. The top end of the pull rod 41 inside the mounting block 34 is provided with an end face ratchet 45. Its tooth structure is adapted to the end face ratchet 54 in the fixing component 5 to prevent the screw 52 from rotating in the opposite direction. The other end of the pull rod 41 extends to the outside and is equipped with a gripper 44, which makes it convenient for the operator to manually control the movement of the pull rod 41, thereby realizing the unlocking operation of the anti-loosening component 4.

[0027] The fixing component 5 includes a U-shaped movable part 50 movably connected to the mounting block 34 via a second rotating shaft 35. The internally threaded cylinder 51 at the tail of the U-shaped movable part 50 forms a threaded engagement with the screw 52. The end face ratchet 54 at the top of the screw 52 interacts with the end face ratchet 45 of the anti-loosening component 4 to restrict the rotation of the screw 52 and prevent it from loosening. The knob 53 at the tail of the screw 52 allows the operator to manually rotate the screw 52 to adjust the clamping force of the U-shaped movable part 50 on the fixing plate 36, thereby achieving a tight connection between the vessel body 1 and the vessel cover 2. The inverted L-shaped limiting rod 56 movably installed on the connector 55 at the top of the U-shaped movable part 50 can rotate to the rear of the knob 53 after the knob 53 is tightened, forming an additional obstruction and further enhancing the limiting effect of the knob 53. This prevents the knob 53 from reversing and moving backward due to accidental collisions or vibrations, thereby improving the stability and reliability of the entire connection structure and ensuring that the vessel body 1 and the vessel cover 2 are tightly connected and will not loosen during use.

[0028] First, carefully fit the left half of the ring shell 30 onto the connection between the vessel body 1 and the vessel cover 2, and carefully check to ensure that it completely covers and fits tightly with the connection without any gaps or deviations, laying the foundation for subsequent fixing operations.

[0029] Then, manually and slowly rotate the right half of the ring shell 32. During the rotation, pay attention to its fit with the vessel body 1 and the vessel cover 2, so that it is precisely fitted into the other side of the connection, forming a complete and stable ring with the left half of the ring shell 30, ensuring that the ring is evenly stressed in the circumferential direction and that there is no local loosening.

[0030] Next, manually and gently rotate the U-shaped movable part 50 to adjust its angle and position so that the fixed plate 36 can be smoothly placed inside the U-shaped movable part 50. Then, steadily turn the knob 53 clockwise by hand. The knob 53 drives the screw 52 to rotate. Due to the precise thread fit between the screw 52 and the internal threaded cylinder 51, the screw 52 will gradually move forward smoothly. When the front end of the screw 52 steadily touches the fixed plate 36, the right half of the ring shell 32 and the left half of the ring shell 30 are tightly clamped under the thrust of the screw 52, ​​so that the vessel body 1 and the vessel cover 2 will not have relative displacement at the connection.

[0031] Simultaneously, as the screw 52 moves forward, it drives the end face ratchet 54 to move forward synchronously, allowing it to pass smoothly through the through hole 37 and accurately insert into the mounting block 34. When the screw 52 abuts against the fixing plate 36 and a "click" is heard, it means that the mating groove and ratchet teeth of the end face ratchet 54 and the end face ratchet 45 are perfectly engaged. (Due to the elastic force of the compression spring 43, the compression spring 43 will push the compression plate 42, which in turn drives the pull rod 41, causing the pull rod 41 to push the end face ratchet 45 forward to tightly engage and fix it with the end face ratchet 54.) This further enhances the stability of the fixation, prevents the screw 52 from accidentally rotating in the opposite direction due to external factors, and ensures that the clamping state of the collar is durable and reliable.

[0032] Finally, manually and carefully rotate the inverted L-shaped limit rod 56 to the appropriate position around the axis, so that the baffle at the tail of the inverted L-shaped limit rod 56 is accurately placed behind the knob 53, which can effectively prevent the knob 53 from moving backward after accidental reversal. This completes the double safety fixation of the connection between the vessel body 1 and the vessel cover 2, which greatly improves the safety and stability of the overall structure.

[0033] When it is necessary to open, the operation steps are as follows: First, firmly grasp the handle 44 with your hand, and then pull the handle 44 backward. The handle 44 will drive the pull rod 41 to move backward, thereby causing the end face ratchet 45 to move backward synchronously with the pull rod 41, thereby releasing the locking state between the end face ratchet 54 and the end face ratchet 45, so that the screw 52 is no longer restricted by the engagement between the end face ratchet 54 and the ratchet. Then, follow the reverse operation of the above installation steps to remove it, and then open the connection between the vessel body 1 and the vessel cover 2.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
