Description

Technical Field

[0001] This utility model relates to the field of mechanical connection technology, specifically a cover support hinge for a plant negative pressure extractor. Background Technology

[0002] In the field of plant extraction and deep processing, plant negative pressure extraction machines play a crucial role as a key piece of equipment. With the increasing demand for natural plant active ingredients and their widespread application in pharmaceuticals, health products, cosmetics, food additives, and other industries, plant negative pressure extraction technology has developed rapidly. This technology, by extracting plant raw materials under negative pressure, can effectively reduce extraction temperature, minimize the loss of heat-sensitive components, and improve extraction efficiency and product quality.

[0003] The structure of a plant negative pressure extraction machine is relatively complex, mainly composed of an extraction tank, a heating system, a vacuum system, a condensation system, and a cover. Among them, the cover, as an important component of the extraction machine, not only serves a sealing function to prevent gas leakage during the extraction process and ensure the stability of the negative pressure environment, but also plays a role in opening and closing the extraction tank when maintaining the equipment, cleaning, or adding or removing plant materials. The key component supporting the opening and closing of the cover is the hinge.

[0004] Currently, the cover support hinges commonly used in plant negative pressure extraction machines on the market typically employ a traditional mechanical hinge structure. This type of hinge generally consists of components such as a hinge seat, a hinge shaft, and a movable blade. The hinge seat is fixedly installed on the tank of the extraction machine, while the movable blade is connected to the cover. The two are connected together by the hinge shaft, allowing the cover to rotate around the hinge shaft, thereby realizing the opening and closing operation of the cover. However, existing support hinges have low stability and short service life.

[0005] Therefore, in order to address the above problems, the applicant needs to design a cover support hinge for a plant negative pressure extraction machine to solve the problem. Utility Model Content

[0006] The purpose of this invention is to provide a cover support hinge for a plant negative pressure extraction machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cover support hinge for a plant negative pressure extractor, comprising a mounting plate, an extension plate fixedly mounted on the mounting plate, a sliding rod mounted on the extension plate, a rotating component rotatably mounted on the sliding rod, a connecting rod rotatably mounted on the rotating component, fixed shells slidably mounted at both ends of the connecting rod, and upright plates fixedly mounted on the fixed shells, a support rod fixedly mounted on the upright plates, the support rod being adapted to the rotating component, a connecting plate rotatably mounted on the connecting rod, and a first fixed rod rotatably mounted at the end of the connecting plate away from the connecting rod, a stabilizing plate fixedly mounted on the first fixed rod, and a base plate fixedly mounted below the stabilizing plate.

[0008] Furthermore, a limiting rod is fixedly provided on the rotating component, and a limiting plate is rotatably provided on the limiting rod. A second fixing rod is rotatably provided on the limiting plate, and the second fixing rod is fixedly connected to the stabilizing plate.

[0009] Through the above structural design, a limiting rod, a limiting plate, and a second fixing rod are set. The rotational connection between the limiting plate and the limiting rod can dynamically limit the rotation angle of the rotating parts, avoiding excessive displacement due to inertia or external force when the cover is opened or closed, thereby improving the stability of the hinge movement.

[0010] Furthermore, a second linkage rod is rotatably mounted on the limiting plate, and a linkage plate is rotatably mounted on the second linkage rod. A first linkage rod is rotatably mounted on the linkage plate, and the first linkage rod is fixedly connected to the extension plate.

[0011] Through the above structural design, the linkage plate forms a multi-level linkage structure through the cooperation of the second linkage rod and the first linkage rod, which can synchronously transmit and distribute the force during the opening and closing of the cover, reducing the problem of load concentration on a single hinge axis.

[0012] Furthermore, a hollow sleeve is rotatably provided on the second linkage rod, and a movable rod is slidably provided inside the hollow sleeve, and the movable rod is rotatably connected to the connecting rod.

[0013] Through the above structural design, the sliding connection between the hollow sleeve and the movable rod can provide an adaptive telescopic function when the cover moves, absorbing the vibration energy generated by rapid opening and closing or external impact.

[0014] Furthermore, a sealing cover is fixedly installed on the mounting plate, and an extraction box is installed below the sealing cover, with the top surface of the extraction box fixedly connected to the bottom surface of the base plate.

[0015] Through the above structural design, the rigid fixation between the base plate and the top surface of the extraction chamber ensures the flatness and fit of the sealing surface when the cover is closed, effectively preventing gas leakage under negative pressure.

[0016] Furthermore, a buffer block is fixedly provided at one end of the support rod, and the buffer block is made of rubber.

[0017] Through the above structural design, the rubber buffer block at the end of the support rod provides elastic buffering when the cover is closed or opened to its limit position, eliminating noise and vibration caused by direct collision of metal parts.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the plant negative pressure extraction machine uses a cover support hinge to facilitate connection and support of the sealing cover of the extraction box, and has strong stability and long service life. The specific details are as follows:

[0019] This plant negative pressure extraction machine uses a cover-supported hinge. Through the dynamic angle limiting design of the limiting rod and limiting plate, combined with the linkage plate, first linkage rod, and second linkage rod, the load is simultaneously distributed and the force coordination is optimized during the opening and closing of the cover, effectively preventing component deformation or jamming. At the same time, the sliding extension mechanism of the hollow sleeve and the movable rod absorbs vibration energy. With the rubber buffer block at the end of the support rod, the impact noise and metal fatigue damage are significantly reduced. Meanwhile, the rigid fixed structure of the sealing cover and the extraction box ensures the negative pressure seal and reduces ineffective opening and closing operations. The synergistic effect of all structures comprehensively improves the stability, impact resistance, and sealing reliability of the hinge, greatly extending its service life and reducing the maintenance frequency.

[0025] 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.

[0026] like Figures 1-4 As shown, the cover support hinge for a plant negative pressure extractor of this utility model includes a mounting plate 1, an extension plate 2 fixedly mounted on the mounting plate 1, a sliding rod 3 mounted on the extension plate 2, a rotating component 4 rotatably mounted on the sliding rod 3, a connecting rod 5 rotatably mounted on the rotating component 4, fixed shells 6 slidably mounted at both ends of the connecting rod 5, a vertical plate 17 fixedly mounted on the fixed shell 6, a support rod 18 fixedly mounted on the vertical plate 17, and the support rod 18 is adapted to the rotating component 4, a connecting plate 7 rotatably mounted on the connecting rod 5, a first fixed rod 8 rotatably mounted at the end of the connecting plate 7 away from the connecting rod 5, a stabilizing plate 9 fixedly mounted on the first fixed rod 8, and a base plate 10 fixedly mounted below the stabilizing plate 9.

[0027] A limiting rod 11 is fixedly installed on the rotating component 4, and a limiting plate 12 is rotatably installed on the limiting rod 11. A second fixing rod 13 is rotatably installed on the limiting plate 12, and the second fixing rod 13 is fixedly connected to the stabilizing plate 9. By setting the limiting rod 11, the limiting plate 12, and the second fixing rod 13, the rotational connection between the limiting plate 12 and the limiting rod 11 can dynamically limit the rotation angle of the rotating component 4, avoiding excessive displacement due to inertia or external force when the cover is opened or closed, thereby improving the stability of the hinge movement. The fixed connection between the second fixing rod 13 and the stabilizing plate 9 further strengthens the supporting rigidity of the limiting plate 12, reduces wear caused by frequent movement of components, and extends service life.

[0028] A second linkage rod 16 is rotatably mounted on the limiting plate 12, and a linkage plate 14 is rotatably mounted on the second linkage rod 16. A first linkage rod 15 is rotatably mounted on the linkage plate 14, and the first linkage rod 15 is fixedly connected to the extension plate 2. The linkage plate 14 forms a multi-level linkage structure through the cooperation of the second linkage rod 16 and the first linkage rod 15. This structure can synchronously transmit and distribute the force during the opening and closing of the cover, reduce the load concentration problem of a single hinge axis, enhance the coordination of the movement of each component, reduce hinge deformation or jamming caused by uneven force, and thus improve the reliability and durability of the overall structure.

[0029] A hollow sleeve 21 is rotatably mounted on the second linkage rod 16. A movable rod 20 is slidably mounted inside the hollow sleeve 21 and is rotatably connected to the connecting rod 5. The sliding connection design between the hollow sleeve 21 and the movable rod 20 can provide an adaptive extension and retraction function when the cover moves, absorbing the vibration energy generated by rapid opening and closing or external impact. The rotatable connection between the movable rod 20 and the connecting rod 5 further optimizes the flexibility of the hinge, avoids stress concentration caused by rigid connection, significantly reduces fatigue damage to key components, and improves the impact resistance of the hinge.

[0030] A sealing cover 22 is fixedly installed on the mounting plate 1. An extraction box 23 is installed below the sealing cover 22, and the top surface of the extraction box 23 is fixedly connected to the bottom surface of the base plate 10. The fixed connection structure between the sealing cover 22 and the extraction box 23, through the rigid fixation of the base plate 10 and the top surface of the extraction box 23, ensures the flatness and fit of the sealing surface when the cover is closed, effectively preventing gas leakage under negative pressure environment, indirectly improving the stability of the hinge, avoiding frequent opening and closing operations due to seal failure, thereby reducing the ineffective wear of the hinge and extending its service life.

[0031] A buffer block 19 is fixedly installed at one end of the support rod 18. The buffer block 19 is made of rubber. The rubber buffer block 19 at the end of the support rod 18 provides elastic buffering when the cover is closed or opened to the limit position, eliminating noise and vibration caused by direct collision of metal parts. The high damping characteristics of rubber can absorb instantaneous impact force, preventing the hinge shaft and connecting parts from deforming or breaking due to repeated impacts, and significantly improving the fatigue resistance and service life of the hinge.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
