Description

Technical Field

[0001] This utility model relates to a assisted hinge structure and belongs to the field of mechanical devices. Background Technology

[0002] With the rapid development of domestic chemical, food and pharmaceutical industries, pressure vessels, reaction kettles and reactors are widely used. These medium and large industrial equipment generally use covers to facilitate operation. In particular, some chemical reaction tanks need to be covered to prevent foreign objects from entering, and the cover needs to guide airflow to prevent gas inside the tank from impacting the operator. However, most covers currently use ordinary hinge structures, which are generally difficult for operators to open. Therefore, a structure that assists in opening the cover is needed. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an assisted hinge structure.

[0004] A power-assisted hinge structure includes an upper rotating seat and a lower rotating seat, which are rotatably connected by a rotating shaft. A spring is sleeved on the rotating shaft, with one end fixed to the rotating shaft and the other end fixed to the lower end of the upper rotating seat. A limiting component for restricting the unidirectional rotation of the spring is connected to one end of the rotating shaft and the lower rotating seat. A limiting sleeve is also sleeved on one side of the spring. By sleeved a spring on the rotating shaft and fixing one end to the shaft and the other end to the lower end of the upper rotating seat, continuous power assistance is provided to the cover when opening, significantly reducing the force required by the operator and avoiding the problems of difficult opening and fatigue associated with traditional hinge structures. The limiting component and the limiting sleeve cooperate to restrict the unidirectional rotation of the spring, resulting in stable and controllable power rebound during opening, while reliably tightening the spring when closing to prevent the cover from rapidly impacting or pinching the operator due to excessive rebound, thus improving safety. The spring-loaded power supply system has built-in energy storage, enabling it to provide auxiliary support at different opening and closing angles without the need for external energy or periodic charging. It is highly reliable and adaptable to various indoor and outdoor environments, and is especially suitable for chemical reaction tank covers that require frequent opening and have requirements for directional airflow.

[0005] Preferably, the limiting sleeve is spirally fitted onto the rotating shaft, with one end of the spring abutting against the spring and the other end abutting against the inner wall of the upper rotating seat. The spiral limiting sleeve and the spiral line of the spring fit together closely, ensuring that the spring is evenly stressed and rebounds smoothly during the opening of the assisted hinge, avoiding the "sudden jump" phenomenon and improving the safety of use.

[0006] Preferably, the upper rotating seat is equipped with spaced-apart upper rotating arms, and the lower rotating seat is equipped with spaced-apart lower rotating arms for connecting with the upper and lower covers. The spaced-apart rotating arms can be flexibly adjusted in position according to the size and weight of the cover, allowing the hinge to adapt to container covers of different sizes, thus improving the product's versatility. The multi-arm distribution enhances the hinge's resistance to torsion and lateral forces on the cover, effectively suppressing shaking and vibration during operation, and improving the safety and reliability of operators during opening and closing.

[0007] Furthermore, an adjusting plate is provided between the upper rotating seats, located behind the upper rotating arm. An adjusting shaft and a mounting plate corresponding to the adjusting plate are provided between the upper rotating arms. Several adjusting bolts are evenly distributed on the mounting plate, with their bottoms abutting against the adjusting plate. These bolts are used to adjust the rotation of the upper rotating arm around the adjusting shaft, thereby adjusting the closing angle of the upper and lower covers. By providing an adjusting plate on the rear side of the upper rotating seat that can cooperate with the mounting plate and adjusting bolts, precise control of the rotation angle of the upper rotating arm around the adjusting shaft is achieved. The closing angle of the upper and lower covers can be finely adjusted according to on-site requirements, ensuring sealing performance and operational comfort. Several adjusting bolts are distributed on the mounting plate, with their bottoms abutting against the adjusting plate. Operators only need to tighten or loosen the bolts to quickly achieve coarse and fine adjustments of the closing angle without replacing parts, significantly improving maintenance efficiency.

[0008] Preferably, the limiting component includes a ratchet seat fixedly connected to the upper rotating seat, the ratchet seat engaging a ratchet gear, and an adjusting nut connected to the ratchet gear via the extending rotating shaft. The ratchet seat engaging the ratchet gear achieves a one-way stopping function for the hinge, allowing the ratchet to rotate freely when the cover is opened and precisely positioning it when closed, effectively preventing the cover from accidentally closing due to its own weight or vibration, thus improving operational safety. The extending rotating shaft to the ratchet gear and connected via the adjusting nut allows for fine adjustment of the preload of the spring through simple screwing.

[0009] Furthermore, the rotating shaft is equipped with a limiting shaft, which extends to both sides of the ratchet gear and is engaged with it via snap-fit ​​pins. Adding a limiting shaft to the rotating shaft and fixing its two ends to the inner wall of the ratchet gear via snap-fit ​​pins ensures reliable coaxial linkage between the limiting shaft and the ratchet assembly, guaranteeing the accuracy and stability of the hinge's opening and closing positioning. This limiting shaft-snap-pin structure is simple and compact, does not occupy additional space, maintains the miniaturization advantage of power-assisted hinges, and is suitable for application in space-constrained chemical equipment or other industrial settings.

[0010] Preferably, a reinforcing pin is also provided between the upper rotating seats, located above the spring. This pin enhances the connection rigidity between the upper rotating seats, reduces minor vibrations and wobbling during opening / closing, and further improves the overall stability and user comfort of the hinge structure.

[0011] Preferably, the upper and lower rotating seats are equipped with protective covers that enclose the mainspring spring. These covers completely enclose the mainspring spring, effectively preventing dust, liquid splashes, or corrosive chemicals from damaging it and improving the hinge's durability in harsh environments. The cover structure also reduces noise or jamming caused by external impurities, ensuring smooth rebound, quiet operation, and a better user experience.

[0012] The beneficial effects of this utility model are as follows: By sleeved a spring on the rotating shaft and fixing one end to the rotating shaft and the other end to the lower end of the upper rotating seat, continuous assistance is provided to the cover plate during opening, significantly reducing the force required by the operator and avoiding the problems of laborious opening and easy fatigue associated with traditional hinge structures. The limiting component and the limiting sleeve cooperate with each other to restrict the unidirectional rotation of the spring, resulting in stable and controllable assisted rebound during opening, while reliably tightening the spring when closing to prevent the cover plate from rapidly impacting or pinching personnel due to excessive rebound, thus improving safety. The spring-type assistance method has its own energy storage, enabling auxiliary support to be provided at different opening and closing angles without the need for external energy or periodic charging. It is highly reliable, adaptable to various indoor and outdoor environments, and is especially suitable for chemical reaction tank covers that require frequent opening and have requirements for directional airflow.

[0021] like Figure 1-3 The diagram illustrates an embodiment of the assisted hinge structure of this invention, comprising an upper rotating seat 1 and a lower rotating seat 2. The upper rotating seat 1 and the lower rotating seat 2 are rotatably connected by a rotating shaft 11. A spring-loaded spring 12 is sleeved on the rotating shaft 11, with one end fixed to the rotating shaft 11 and the other end fixed to the lower end of the upper rotating seat 1. A limiting component 3 for restricting the unidirectional rotation of the spring-loaded spring 12 extends from one end of the rotating shaft 11 and connects to the upper rotating seat 1 and lower rotating seat 2. A limiting sleeve 13 is also sleeved on one side of the spring-loaded spring 12. By sleeved with a spring-loaded spring 12 on the rotating shaft 11 and fixing one end to the rotating shaft 11 and the other end to the lower end of the upper rotating seat 1, continuous assistance is provided to the cover plate when opening, significantly reducing the force required by the operator and avoiding the problems of difficult and fatigue-inducing opening of traditional hinge structures. The limiting component 3 and the limiting sleeve 13 work together to restrict the unidirectional rotation of the spring 12, providing stable and controllable assisted rebound during opening and reliably tightening the spring when closing, preventing the cover from rapidly impacting or pinching personnel due to excessive rebound, thus improving safety. The spring-driven assisted mechanism has built-in energy storage, providing auxiliary support at different opening angles without requiring external energy or periodic recharging. It is highly reliable, adaptable to various indoor and outdoor environments, and particularly suitable for chemical reaction tank covers that require frequent opening and require controlled airflow.

[0022] Preferably, the limiting sleeve 13 is spirally sleeved on the rotating shaft 11, and one end of the spring 12 abuts against the spring 12, while the other end abuts against the inner wall of the upper rotating seat 1. The spiral limiting sleeve 13 and the spiral line of the spring 12 fit together, ensuring that the spring is evenly stressed and rebounds smoothly during the opening of the assisted hinge, avoiding the "sudden jump" phenomenon and improving the safety of use.

[0023] Preferably, the upper rotating seat 1 is equipped with spaced-apart upper rotating arms 14, and the lower rotating seat 2 is equipped with spaced-apart lower rotating arms 21 for connecting with the upper and lower covers. The spaced-apart rotating arms can be flexibly adjusted in position according to the size and weight of the cover, allowing the hinge to adapt to container covers of different sizes, thus improving the product's versatility. The multi-arm distribution enhances the hinge's resistance to torsion and lateral forces on the cover, effectively suppressing shaking and vibration during operation, and improving the safety and reliability of operators during opening and closing.

[0024] Furthermore, an adjusting plate 15 is provided between the upper rotating seats 1 and the upper rotating arm 14, located behind the upper rotating arm 14. An adjusting shaft 19 and a mounting plate 22 corresponding to the adjusting plate 15 are provided between the upper rotating arms 14. Several adjusting bolts 23 are evenly distributed on the mounting plate 22. The bottom of each adjusting bolt 23 abuts against the adjusting plate 15 and is used to adjust the rotation of the upper rotating arm 14 around the adjusting shaft 19, thereby adjusting the closing angle of the upper and lower covers. By providing an adjusting plate 15 on the rear side of the upper rotating seat 1 that can cooperate with the mounting plate 22 and adjusting bolts 23, precise control of the rotation angle of the upper rotating arm 14 around the adjusting shaft 19 is achieved. The closing angle of the upper and lower covers can be finely adjusted according to on-site requirements, ensuring sealing performance and operational comfort. Several adjusting bolts 23 are distributed on the mounting plate 22, with their bottoms abutting against the adjusting plate 15. Operators only need to tighten or loosen the bolts to quickly achieve coarse and fine adjustments of the closing angle without replacing parts, significantly improving maintenance efficiency.

[0025] Preferably, the limiting component 3 includes a ratchet seat 31 fixedly connected to the upper rotating seat 1. The ratchet seat 31 engages with a ratchet gear 32, and the rotating shaft 11 extends to the ratchet gear 32 and is connected to an adjusting nut 33. The ratchet seat 31 engaging with the ratchet gear 32 realizes the one-way stopping function of the hinge. When the cover is opened, the ratchet rotates freely, and when closed, it is precisely positioned, effectively preventing the cover from closing accidentally due to its own weight or vibration, thus improving operational safety. The rotating shaft 11 extends to the ratchet gear 32 and is connected through the adjusting nut 33. The adjusting nut 33 can be used to finely adjust the preload of the spring 12 by simple screwing.

[0026] Furthermore, the rotating shaft 11 is provided with a limiting shaft 16, which extends to both sides of the ratchet 32 ​​and is engaged with it via snap-fit ​​pins. The addition of the limiting shaft 16 to the rotating shaft 11, and the fixing of its two ends to the inner wall of the ratchet 32 ​​via snap-fit ​​pins, ensures reliable coaxial linkage between the limiting shaft 16 and the ratchet assembly, guaranteeing the accuracy and stability of the hinge's opening and closing positioning. This limiting shaft 16-snap-fit ​​pin structure is simple and compact, does not occupy additional space, maintains the miniaturization advantage of the power-assisted hinge, and is convenient for application in space-constrained chemical equipment or other industrial applications.

[0027] Preferably, a reinforcing pin 17 is also provided between the upper rotating seats 1, located above the spring 12. This pin enhances the connection rigidity between the upper rotating seats 1, reduces minor vibrations and wobbling during opening / closing, and further improves the overall stability and user comfort of the hinge structure.

[0028] Preferably, the upper rotating seat 1 and the lower rotating seat 2 are provided with protective covers 18 that enclose the mainspring spring 12. By providing these covers on the upper rotating seat 1 and the lower rotating seat 2, the mainspring spring 12 is completely enclosed, effectively preventing dust, liquid splashes, or corrosive chemical media from eroding the spring and improving the hinge's durability in harsh environments. The cover structure reduces abnormal noises or jamming caused by external impurities, ensuring smooth power assist rebound, quiet operation, and improved user experience.
