Description

Technical Field

[0001] This application relates to the field of constant temperature chambers, specifically to a multi-stage temperature-controlled constant temperature chamber. Background Technology

[0002] Incubators are core equipment in biological experiments, maintaining the stability of critical processes such as cell culture, microbial reproduction, and enzyme reactions. Through precise temperature control systems, they simulate the constant environment required for specific biological activities, avoiding interference from temperature fluctuations on cell metabolic rates, gene expression, or chemical reaction processes. Especially in long-term cultures, gradient experiments, or the preservation of sensitive samples, temperature control performance directly determines the reliability and reproducibility of experimental data. However, traditional incubators have significant shortcomings in terms of ease of operation and human-computer interaction design. Their built-in shelves are mostly static, unable to slide outwards. When retrieving culture dishes, test tubes, or microplates, operators must fully extend their arms into the narrow space inside the incubator, easily touching adjacent samples and causing cross-contamination or spillage. In high-temperature experiments, this increases the risk of burns from contact with the hot air inside the incubator or the edges of the metal shelves. Furthermore, fixed shelves force operators to frequently open and close the incubator door to adjust sample positions, exacerbating the interference of temperature fluctuations on the experimental process. Repeated bending and leaning also reduce work efficiency, and long-term operation may lead to muscle strain for operators. This inefficient and unsafe design is increasingly out of place in modern biological research, which strives for high-throughput, automated, and humanized experimental procedures.

[0003] Therefore, in order to solve the above problems, this application provides a multi-stage temperature-controlled constant temperature chamber that facilitates the handling of contents such as petri dishes by operators. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage temperature-controlled constant temperature chamber, which aims to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage temperature-controlled constant temperature chamber, comprising a chamber body, an array of partition plates, and a sliding plate; the rear end of the partition plate is fixedly connected to the chamber body, the lower end of the sliding plate is slidably connected to the upper end of the partition plate, a rack is fixedly connected to the lower side of the sliding plate, a gear that meshes with the rack is rotatably connected to the side of the partition plate, a torsion spring is provided for the rotatable connection between the gear and the partition plate, and an auxiliary mechanism is provided on the inner wall of the side of the chamber body;

[0006] The auxiliary mechanism includes a locking pin and a locking plate. The locking pin is located on the side of the gear, and the locking plate is located at the rear end of the sliding plate. The gear is driven to rotate by the torsion spring, which causes the rack to move. The sliding plate is driven to move horizontally by the rack. The locking plate is driven by the sliding plate to lock the locking pin with the gear.

[0007] The gears, driven by a torsion spring, drive a rack and pinion to displace a sliding plate, allowing the plate to slide automatically outwards from the container. This facilitates the loading and unloading of contents without requiring manual pulling. A locking pin locks the gears, stopping the plate at any point during sliding. After operation, pushing the plate back displaces a retaining plate, which in turn locks the gears again. This further reduces operator workload, simplifies operation, prevents safety hazards, and reduces physical labor.

[0008] Furthermore, a temperature control unit is installed at the rear of the enclosure, which performs multi-level temperature control inside the enclosure. A door is rotatably installed at the front of the enclosure, and a control panel and handle are installed on the surface of the door. The sliding plate is slidably connected to the inner wall of the enclosure on both sides. The sliding connection between the sliding plate and the partition plate is equipped with a limit. A receiving groove is opened at the rear side of the enclosure, and a through hole is opened on the side of the enclosure, which communicates with the receiving groove.

[0009] Furthermore, the auxiliary mechanism also includes a rotating handle, a rotating rod, and a telescopic rod. The rotating rod is movably connected to the inner wall of the housing through a through hole. One end of the rotating rod is rotatably connected to a locking pin, and the rotating rod passes through the locking pin and is inserted into the rotating handle. The other end of the rotating rod is inserted into a retaining plate, which is positioned inside the receiving groove. One end of the telescopic rod is fixedly connected to the end of the locking pin, and the other end of the telescopic rod is fixedly connected to the side of the housing. The rotating connection between the rotating rod and the locking pin is equipped with a limit switch, so that when the rotating rod undergoes horizontal displacement, it drives the locking pin to move synchronously, while ensuring that the rotating rod can only rotate at a certain angle. A torsion spring is provided for the rotating connection between the rotating rod and the locking pin. The locking pin has an L-shaped structure, with one end engaging with a disengaged gear, and the other end fixed to the telescopic rod. The rotating rod passes through the middle of the locking pin.

[0010] Compared with existing technologies, it has the following beneficial effects:

[0011] This invention provides a multi-stage temperature-controlled constant temperature chamber. A gear, driven by a torsion spring, drives a rack and pinion to displace a sliding plate, allowing the plate to automatically slide outwards from the chamber. This facilitates the loading and unloading of contents without requiring manual pulling. A locking pin locks the gear, stopping the sliding plate at any point during movement. After operation, pushing the sliding plate back displaces a retaining plate at its rear, which in turn locks the gear again. This further reduces operator workload, simplifies operation, prevents safety hazards, and reduces physical labor. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Please see Figures 1 to 6 As shown, this utility model provides the following technical solution: a multi-stage temperature-controlled constant temperature chamber, including a chamber body 1, an array of partition plates 2, and a sliding plate 3; the rear end of the partition plate 2 is fixedly connected to the chamber body 1, the lower end of the sliding plate 3 is slidably connected to the upper end of the partition plate 2, a rack 4 is fixedly connected to the lower side of the sliding plate 3, a gear 5 that meshes with the rack 4 is rotatably connected to the side of the partition plate 2, a torsion spring is provided for the rotatable connection between the gear 5 and the partition plate 2, and an auxiliary mechanism 6 is provided on the inner wall of the side of the chamber body 1;

[0021] The auxiliary mechanism 6 includes a locking pin 7 and a locking plate 8. The locking pin 7 is located on the side of the gear 5, and the locking plate 8 is located at the rear end of the sliding plate 3. The gear 5 is driven to rotate by the torsion spring, which causes the rack 4 to move. The sliding plate 3 is driven to move horizontally by the rack 4. The locking plate 8 is driven by the sliding plate 3 to lock the locking pin 7 with the gear 5.

[0022] The rear of the enclosure 1 is equipped with a temperature control unit, which performs multi-level temperature control on the interior of the enclosure 1. The temperature control unit includes a heating module and a cooling module. The inner wall of the enclosure 1 is equipped with a fan plate that is connected to the temperature control unit.

[0023] See Figure 1 The front end of the enclosure 1 is equipped with a rotating door 11, and the surface of the door 11 is equipped with a control panel 12 and a handle 13. One end of the door 11 is equipped with a locking block that engages with the enclosure 1; the control panel 12 is electrically connected to the temperature control unit to set the working status of the temperature control box and monitor it in real time.

[0024] See Figure 2 The sliding plate 3 is slidably connected to the inner wall of the box 1 on both sides. The sliding connection between the sliding plate 3 and the partition plate 2 is provided with a limit. The upper end of the partition plate 2 is provided with a slider, and the lower end of the sliding plate 3 is provided with a groove. The limit setting prevents the sliding plate 3 from completely detaching from the partition plate 2. Thus, when the sliding plate 3 slides out of the box 1, the partition plate 2 still supports the sliding plate 3.

[0025] Both the partition plate 2 and the sliding plate 3 are made of mesh to facilitate the flow of temperature inside the box 1.

[0026] As another embodiment, such as Figures 2 to 6 As shown, a receiving groove 14 is provided at the rear end of the side of the box body 1, and a through hole 15 is provided on the side of the box body 1, which communicates with the receiving groove 14. The card plate 8 is positioned in the receiving groove 14. The setting of the receiving groove 14 provides space for the card plate 8 to move in a circular motion, so that the card plate 8 can move to the rear of the sliding plate 3 or disengage from the rear of the sliding plate 3 during the circular motion.

[0027] See Figure 3 as well as Figure 4 The auxiliary mechanism 6 also includes a rotating handle 61, a rotating rod 62, and a telescopic rod 63; the rotating rod 62 is movably connected to the inner wall of the box 1 through the through hole 15, one end of the rotating rod 62 is rotatably connected to the locking pin 7, the rotating rod 62 passes through the locking pin 7 and is inserted into the rotating handle 61, the other end of the rotating rod 62 is inserted into the card plate 8, the card plate 8 is positioned inside the receiving groove 14, one end of the telescopic rod 63 is fixedly connected to the end of the locking pin 7, and the other end of the telescopic rod 63 is fixedly connected to the side of the box 1.

[0028] In the initial state, the locking plate 8 is located behind the sliding plate 3 and abuts against the sliding plate 3. The locking pin 7 is inserted into the gear 5 to lock the gear 5. When the experimenter takes out or observes the contents of the box 1, the box door 11 is opened, and then the rotating handle 61 on the side of the sliding plate 3 that needs to be pulled out is rotated. The rotating handle 61 drives the rotating rod 62 to rotate. The rotation of the rotating rod 62 causes the locking plate 8 to move away from the rear of the sliding plate 3 in a circular motion. At this time, the rotating handle 61 can be pulled to move horizontally, so that the locking pin 7 disengages from the gear 5. The gear 5 is disengaged and rotates under the force of the torsion spring, which in turn drives the rack 4 that meshes with it to move horizontally, causing the sliding plate 3 to move along the partition plate 2, thereby sliding out of the box 1.

[0029] It should be noted that the rotational connection between the rotating rod 62 and the locking pin 7 is equipped with a limit switch, so that when the rotating rod 62 undergoes horizontal displacement, it drives the locking pin 7 to move synchronously, while also ensuring that the rotating rod 62 can only rotate within a certain angle. The rotation of the rotating rod 62 can only cause the locking plate 8 to undergo a certain angle of circular motion, allowing the locking plate 8 to switch between being positioned behind or away from the sliding plate 3, but preventing it from rotating over a large range.

[0030] In addition, a torsion spring is provided for the rotatable connection between the rotating rod 62 and the locking pin 7. The rotating rod 62 with the torsion spring here tends to drive the locking plate 8 to rotate to the rear position of the sliding plate 3, so that after the experimenter completes the sliding of the sliding plate 3 and releases the rotating handle 61, the force of the torsion spring drives the rotating rod 62 to rotate in the opposite direction, so that the locking plate 8 returns to the initial position.

[0031] When the sliding plate 3 slides outward from the housing 1, the experimenter can push the rotating handle 61 to move horizontally in the opposite direction at any time, thereby locking the locking pin 7 into the gear 5 to lock the displacement of the sliding plate 3. There is no need to wait for the sliding plate 3 to slide out completely, which makes it easier for the operator to operate according to actual needs and effectively improves work efficiency.

[0032] Furthermore, the locking pin 7 has an L-shaped structure. One end of the locking pin 7 is disengaged from the gear 5, and the other end of the locking pin 7 is fixed to the telescopic rod 63. The rotating rod 62 passes through the middle of the locking pin 7.

[0033] After the operation is completed, keep the locking pin 7 disengaged from the gear 5 and directly push the sliding plate 3 back to the housing 1. The rear end of the sliding plate 3 contacts the clamping plate 8 during sliding, causing the clamping plate 8 to move backward, which in turn causes the rotating rod 62 to move horizontally. The horizontal displacement of the rotating rod 62 causes the locking pin 7 to move in the same direction, and the locking pin 7 is inserted into the gear 5 to lock. There is no need for the experimenter to manually lock it, and the device returns to the initial state.

[0034] Working principle: In use, manually rotating the handle 61 causes the lever 62 to rotate, which in turn causes the locking plate 8 to move away from the sliding plate 3 in a circular motion. This pulls the handle 61 to move horizontally, causing the locking pin 7 to disengage from the gear 5. The gear 5, under the force of the torsion spring, rotates and drives the rack 4 to move horizontally, causing the sliding plate 3 to slide out of the housing 1 along the partition plate 2. During the sliding process, the handle 61 can be pushed to move horizontally in the opposite direction at any time, thereby engaging the locking pin 7 into the gear 5 to lock the displacement of the sliding plate 3. After the operation is completed, the sliding plate 3 is pushed back to the housing 1. The rear end of the sliding plate 3 contacts the locking plate 8 during the sliding process, causing the locking plate 8 to move backward, which in turn causes the locking pin 7 to move in the same direction. The locking pin 7 then inserts into the gear 5 to lock, and the device returns to its initial state.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
