Description

Technical Field

[0001] This invention relates to the field of oscillating incubator technology, specifically to an adjustable support mechanism for opening the door of an oscillating incubator. Background Technology

[0002] Shaking incubators are indispensable laboratory equipment in the fields of life sciences, microbiology and medical research. They are widely used in experiments such as bacterial culture, fermentation, hybridization and enzyme reactions. Such equipment usually requires good temperature and humidity control accuracy and a stable shaking environment. In order to facilitate the periodic sampling or observation by the experimenters, most existing shaking incubators adopt a top-opening door structure. However, in the existing technology, the support structure of the top-opening door generally has the following technical defects.

[0003] Firstly, the operation is laborious and lacks hovering stability: Traditional top-opening boxes often use ordinary hinges with simple support rods. Due to the large weight of the box, the operator needs to apply a large upward pulling force when opening it. Moreover, the inertia at the moment of opening is large, which can easily generate impact noise. If the hand is released too quickly when closing, the box will fall rapidly under the action of gravity, which may cause fingers to be pinched or the sealing strip to be damaged. When the experimenter needs to open the box to take out or put in samples, it is often difficult to find a suitable support point, which causes the box to shake. This not only affects the operating efficiency, but also poses a safety hazard of sample spillage. Secondly, maintenance is difficult and disassembly costs are high: Existing support mechanisms are usually welded to the housing or fixed with a large number of non-standard fasteners. The structure is too integrated and lacks modular design. When the equipment needs to be deeply cleaned, such as to prevent cross-contamination or mechanical fatigue damage to the support components, the disassembly process is extremely cumbersome. It often requires the removal of a large area of ​​side plates or top plates, and even requires professional maintenance personnel to come to the site. This not only greatly increases the time cost of later maintenance, but also reduces the utilization rate of the equipment.

[0004] Therefore, an adjustable support mechanism for opening the door of a shaking incubator is proposed to address the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of existing support mechanisms for opening the door of an oscillating incubator, such as laborious operation, lack of hovering stability, difficult maintenance, and high disassembly and assembly costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An adjustable support mechanism for an opening door on a shaking incubator includes a shaking incubator body, an upper opening door, a first observation window, a preset incubator slot, a coupling rod, a pre-assembled shell, an adjustable support mechanism, a preset channel, an upper shell, and a second observation window. The upper opening door is located at the front end of the shaking incubator body. The first observation window is fixedly connected inside the upper opening door. Pre-assembled slots are symmetrically distributed on the left and right sides of the rear end of the upper opening door. A coupling rod is located at the rear end of the upper opening door.

A preset channel is located inside the front end of the shaking incubator body. An upper shell is detachably connected to the top of the shaking incubator body. The second observation window is fixedly connected inside the upper shell.

[0007] Preferably, the adjustable support mechanism includes a mounting plate, a limiting plate, a main movable link, a secondary movable link, and a mounting frame.

The output end of a gas spring support rod is fixedly installed and connected to one end of the hinge seat, and the other end of the gas spring support rod is rotatably connected to the support rod connector via a pin assembly.

[0010] Preferably, one end of the support rod connector is detachably connected to the interior of the mounting plate.

[0011] Preferably, the left and right sides of the coupling rod are detachably connected to one end of the inner side of the main movable connecting rod via square sleeves and bolts.

In this invention, the oscillating incubator body, upper opening door, first observation window, preset chamber groove, coupling rod, pre-assembled shell, adjustable support mechanism, preset channel, upper shell and second observation window have the advantages of easy opening and free hovering. The gas spring support rod combined with the linkage design of multi-link makes full use of the constant force characteristics of the gas spring, providing assistance when opening the door and providing buffer when closing the door. After opening, the thrust of the gas spring and the weight of the door are naturally balanced, realizing stepless hovering of the door during the opening process, which greatly facilitates the operation of the experimenters to pick up and put down the door. 2.

Those skilled in the art can understand the specific meaning of the above terms in the invention based on the specific circumstances.

[0019] Please see Figures 1-5 The present invention provides a technical solution: An adjustable support mechanism for an opening door on a shaking incubator includes a shaking incubator body 1, an upper opening door 2, a first observation window 3, a preset incubator groove 4, a coupling rod 5, a pre-assembled shell 6, an adjustable support mechanism 7, a preset channel 8, an upper shell 9, and a second observation window 10. The upper opening door 2 is provided at the front end of the shaking incubator body 1, and the first observation window 3 is fixedly connected inside the upper opening door 2. The preset incubator grooves 4 are symmetrically distributed on the left and right sides of the rear end of the upper opening door 2. The coupling rod 5 is provided at the rear end of the upper opening door 2, and the pre-assembled shells 6 are symmetrically distributed on the left and right sides of the coupling rod 5. The adjustable support mechanism 7 is installed inside the pre-assembled shell 6. The preset channel 8 is provided inside the front end of the shaking incubator body 1. The upper shell 9 is detachably connected to the top of the shaking incubator body 1, and the second observation window 10 is fixedly connected inside the upper shell 9.

[0020] The adjustable support mechanism 7 includes a mounting plate 71, a limiting plate 72, a main movable connecting rod 73, a secondary movable connecting rod 74, and a mounting frame 75. The mounting plate 71 is detachably fixed to both ends of the limiting plate 72. The upper end of the limiting plate 72 is fitted with a rotating shaft to rotatably connect the main movable connecting rod 73, and the lower end of the limiting plate 72 is fitted with a rotating shaft to rotatably connect the secondary movable connecting rod 74. The lower interior of the main movable connecting rod 73 is rotatably connected to the upper interior of the mounting frame 75 with a pin, and the lower interior of the secondary movable connecting rod 74 is rotatably connected to the lower interior of the mounting frame 75 with a pin. Through the above arrangement, the mounting plate 71 and both ends of the limiting plate 72 are detachably fixed to form a mechanism base, and the main movable connecting rod 73 is rotatably connected to the upper and lower ends of the limiting plate 72 via rotating shafts. Linkage 73 and auxiliary movable link 74 are connected by pivot pins at the bottom of the two links to the upper and lower internal parts of the mounting frame plate 75, forming a parallel four-bar linkage transmission structure with the mounting support plate 71 as the fixed end and the mounting frame plate 75 as the movable end. When the upper opening door 2 opens and closes, the main movable link 73 and auxiliary movable link 74 rotate synchronously around the limiting plate 72, driving the mounting frame plate 75 and the door to rise and fall smoothly. The geometric constraints of the links ensure stable motion trajectory and even force distribution to improve support rigidity. At the same time, the detachable fixed and rotating connection structures facilitate the individual assembly, adjustment, lubrication, and later maintenance and replacement of each component of the mechanism, achieving a unity of modularity, high stability, and easy maintenance of the support mechanism. The pivot pins in the middle section of the main movable link 73 and the auxiliary movable link 74 are connected by pivot pins at the bottom of the two links. The internal pin of the main movable link 73 and the internal pin of the auxiliary connecting rod 74 are rotatably connected in a fitted manner. Through the above arrangement, the middle pins of the main movable link 73 and the secondary movable link 74 are respectively rotatably connected in a fitted manner to the internal pins of the auxiliary connecting rod 76, forming an intermediate constraint link in the multi-link coordinated transmission. During the opening and closing of the upper opening door 2, the relative motion trajectory of the main movable link 73 and the secondary movable link 74 is restricted, so that the two maintain synchronous deflection and geometric parallelism, thereby evenly distributing the door's gravitational torque, improving the overall rigidity and motion stability of the support mechanism. At the same time, the detachable connection method of the pin fitting rotation not only meets the adaptive angle adjustment of the rotating pair and avoids mechanism jamming and interference, but also facilitates the individual lubrication, inspection or replacement of each link and pin in the later stage, strengthening modular maintenance. For convenience, a hinge seat 77 is rotatably connected to the upper part of the main movable link 73 via a pin assembly. The output end of a gas spring support rod 78 is fixedly installed at one end of the hinge seat 77, and the other end of the gas spring support rod 78 is rotatably connected to a support rod connector 79 via a pin. Through this arrangement, the pin rotatably connects the upper part of the main movable link 73 to the hinge seat 77, and fixes the output end of the gas spring support rod 78 at one end of the hinge seat 77, while the other end is rotatably connected to the support rod connector 79 via a pin. This forms a gas spring linkage mechanism with the mounting plate 71 as a fixed fulcrum. During the opening or closing of the top-opening door 2, the gas spring extends and retracts synchronously with the rotation angle of the main movable link 73, utilizing its constant force characteristic to provide opening assistance and closing buffer.The angles are adaptively fine-tuned through each rotating joint to avoid motion interference. Meanwhile, the detachable pins and connecting structures facilitate individual inspection, replacement, and adjustment of the gas spring and hinge components, ensuring the long-term stability and ease of maintenance of the support mechanism. One end of the support rod connector 79 is detachably connected to the mounting plate 71. This detachable connection fixes the support rod connector 79 to one end of the mounting plate 71, providing a stable bottom hinge fulcrum for the gas spring support rod 78. This ensures that the thrust and buffering force of the gas spring can be effectively utilized during the opening and closing of the top-opening door 2. The gas spring assembly is transferred to the fixed frame and features a detachable structure for easy replacement, maintenance, or adjustment of its installation position. This avoids disassembling the entire support mechanism, improving the ease of maintenance and component reusability. The left and right sides of the coupling rod 5 are detachably connected to one end of the main movable connecting rod 73 via square sleeves and bolts. This detachable connection of the square sleeves and bolts securely fixes the coupling rod 5 to the inner end of the main movable connecting rod 73, achieving effective transmission of power and torque during the opening / closing of the top-opening door 2, and ensuring the safety of the connection. The structure maintains stability and torsional stiffness under frequent movement. Simultaneously, the detachable design facilitates independent maintenance, replacement, or adjustment of the connecting rod length of the adjustable support mechanism 7, improving the modular maintenance convenience and assembly flexibility of the equipment. The mounting frame plate 75 has internal slots that are detachably connected to the inner wall of the pre-set box groove 4 via bolts. The mounting support plate 71 is detachably connected to the interior of the pre-installed shell 6 via bolts. The upper shell 9 is opened, and the pre-installed shell 6 is inserted from top to bottom into the pre-set channel 8. The interior of the left side of the upper shell 9 and the interior above the left side of the pre-installed shell 6 are connected via... The bolts are detachably connected. Through the above-mentioned configuration, the detachable bolt connection and the cooperation with the preset channel 8 enable modular fastening between the rear mounting frame plate 75 of the adjustable support mechanism 7 and the upper opening door 2, and between the front mounting support plate 71 and the pre-installed shell 6. Furthermore, the bolt linkage between the upper shell 9 and the pre-installed shell 6 completes the top sealing and positioning of the overall structure. This ensures the stability of force transmission of the adjustable support mechanism 7 during the opening / closing of the upper opening door 2, and also provides the adjustable support mechanism 7, the pre-installed shell 6, and the upper shell 9 with the advantages of quick assembly and disassembly, facilitating later maintenance and cleaning.

[0021] Workflow: First, the adjustable support mechanism 7 is pre-assembled. The mounting plate 71 and the limiting plate 72 are internally fixedly connected by multiple sets of bolts to form the fixed base of the support mechanism. The main movable connecting rod 73 is rotatably connected to the pivot above the limiting plate 72, and the secondary movable connecting rod 74 is rotatably connected to the pivot below. The mounting frame plate 75 is respectively installed inside the main movable connecting rod 73 and the secondary movable connecting rod 74 via pins, forming a preliminary four-bar linkage structure. The auxiliary connecting rod 76 is rotatably connected to the internal pivot of the main movable connecting rod 73 and the secondary movable connecting rod 74 via pins, completing the overall pre-assembly of the support mechanism. The main movable connecting rod 73 is then installed inside the main movable connecting rod 73 via pins. Rotate the hinge seat 77 to fix the output end of the gas spring support rod 78 inside one end of the hinge seat 77. The other end is rotatably connected to the support rod connector 79 via a pin. Finally, the inside of one end of the support rod connector 79 is detachably connected to the inside of the mounting plate 71 via bolts. At this point, the adjustable support mechanism 7 is pre-assembled. Then, assemble the door and the main body. The left and right sides of the coupling rod 5 are detachably connected to one end of the inner side of the main movable connecting rod 73 via square sleeves and bolts. Align the symmetrical pre-set box grooves 4 on the left and right sides of the rear end of the top-opening box door 2 with the grooves inside the mounting frame plate 75 and detachably connect them via bolts. Finally, detachably connect the inside of the mounting plate 71 to the inside of the pre-assembled shell 6 via bolts. The adjustment support mechanism 7 is fixed to the side of the box body. The preset channel 8 inside the front end of the shaking incubator body 1 is cleaned. The pre-installed shell 6 is inserted into the preset channel 8 from top to bottom. The upper shell 9 is placed on top of the shaking incubator body 1. The interior of the left side of the upper shell 9 and the interior of the upper left pre-installed shell 6 are detachably connected by bolts to complete the sealing of the entire shell. Specifically, the operator holds the upper opening door 2 and pulls it upward. At this time, the gas spring support rod 78 extends under the drive of the hinge seat 77, releasing the auxiliary thrust. At the same time, the four-bar linkage composed of the main moving link 73, the secondary moving link 74 and the auxiliary link 76 unfolds synchronously under the constraint of the rotating shaft and the pin shaft, driving the mounting frame plate 75 and the upper opening door 2 to open. The upper door 2 opens smoothly. When the upper door 2 is opened to the desired position, the thrust generated by the gas spring support rod 78 and the weight of the upper door 2 reach a dynamic balance. The door can be stably suspended in any position without additional manual support or locking. When closing the door, the operator pushes the upper door 2 inward, and the four-bar linkage retracts accordingly. The gas spring support rod 78 is compressed and absorbs energy, which plays a role in buffering and preventing hand pinching until the upper door 2 is completely closed at the front end of the shaking incubator body 1. If cleaning or maintenance is required, the fixing bolts of the upper shell 9 can be removed first, the upper shell 9 can be removed, and then the connection between the pre-installed shell 6 and the preset channel 8 can be loosened in sequence. The entire adjustable support mechanism 7 along with the upper door 2 can be removed as a whole for easy internal cleaning.
