Description

Technical Field

[0001] This utility model relates to the field of constant temperature box technology, and in particular to a constant temperature box for biological storage. Background Technology

[0002] In many fields such as biological research, medicine, and pharmaceuticals, it is often necessary to store various biological samples, drugs, and reagents. These biological products have extremely strict requirements for the temperature of the storage environment. Even slight temperature fluctuations can lead to problems such as reduced biological activity, drug inactivation, or reagent deterioration. Therefore, incubators are needed to store biological products.

[0003] Existing technology, such as the biological laboratory incubator disclosed in publication number CN221386504U, includes a chamber body. An internal fan assembly is installed within the chamber body, and a clamping assembly is located on one side of the chamber body. The fan assembly includes a mounting frame, with a fixed fan mounted on the inner wall of the mounting frame and a heater installed on the inner wall of the mounting frame. A ventilation slot is provided at the bottom of the chamber body, and a dustproof net is detachably connected to the bottom of the chamber body. A fixing bolt is provided on the outer wall of the dustproof net. An exhaust pipe is fixedly connected to one side of the chamber body, and the clamping assembly includes a nut. This biological laboratory incubator, equipped with a mounting frame, a fixed fan, a heater, a ventilation slot, a dustproof net, fixing bolts, and an exhaust pipe, allows the fixed fan and heater to blow air, rapidly dissipating heat into the chamber body, ensuring that multiple culture dishes maintain the same heating temperature, thus meeting current needs.

[0004] Therefore, when using the aforementioned device, it is inconvenient to rotate the biological products for uniform heating, so that the biological products near the air outlet can quickly come into contact with the regulated airflow and reach the set temperature rapidly; while the transfer of heat or cold air is hindered for biological products located at the edge or corner of the storage tray, or blocked by other objects, resulting in a slow temperature rise or fall. This leads to a significant temperature gradient between biological products in the same storage tray, affecting the quality of biological product storage. Utility Model Content

[0005] To overcome the problem that a common type of constant temperature box used for biological storage is inconvenient for rotating biological products for uniform heating.

[0006] The technical solution of this utility model is as follows: it includes a constant temperature chamber body, a rotating shaft installed on the outer wall of the constant temperature chamber body, a chamber door installed on the outer wall of the rotating shaft, a uniform heating mechanism fixedly connected inside the constant temperature chamber body, the uniform heating mechanism including a base fixedly installed inside the constant temperature chamber body, a drive motor fixedly connected inside the base, a first rotating rod fixedly connected to the output shaft of the drive motor through a coupling, a first bevel gear fixedly connected to one end of the first rotating rod, a second bevel gear movably connected to the outer wall of the first bevel gear, a second rotating rod fixedly connected to the inner wall of the second bevel gear, and a first storage tray fixedly connected to the top end of the second rotating rod.

[0007] Preferably, the base has a docking groove inside, and the bottom of the first storage tray is fixedly connected to a docking ring. The docking ring is located in the docking groove, and the docking ring and the base form a rotating structure through the docking groove.

[0008] Preferably, the first storage tray has an clearance groove inside, the top of the base is fixedly connected to a bracket, the bracket has a movable shaft installed inside, and the outer wall of the movable shaft is equipped with a guide roller.

[0009] Preferably, the guide roller is connected to the bracket via a movable shaft to form a rotating structure, and the guide roller is movably connected to the first storage tray via a clearance groove.

[0010] Preferably, the first bevel gear forms a rotating structure with the base via the first rotating rod, the first bevel gear meshes with the second bevel gear, the second bevel gear forms a rotating structure with the base via the second rotating rod, and the first storage tray forms a rotating structure with the base via the second rotating rod.

[0011] Preferably, the top of the first storage tray is fixedly connected to an assembly mechanism, the assembly mechanism including a support column fixedly installed on the top of the first storage tray, the inside of the support column having a slot, the outer wall of the support column having a second storage tray, the inside of the second storage tray having a slot, the inner side wall of the slot having a movable groove, the inside of the movable groove having an arc-shaped limiting plate movably connected, and the outer wall of the arc-shaped limiting plate being fixedly connected to a return spring.

[0012] Preferably, the support column is engaged with the second storage tray via a slot, the arc-shaped limiting plate forms a sliding structure with the second storage tray via a movable groove, the arc-shaped limiting plate is engaged with the support column via a slot, and the arc-shaped limiting plate is symmetrically arranged about the central axis of the second storage tray.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a constant temperature chamber body, a uniform heating mechanism, a clearance groove and a guide roller, can cause the first rotating rod to rotate by starting the drive motor, which in turn causes the first bevel gear to rotate, which in turn causes the second bevel gear to rotate, causing the first storage tray fixedly connected to the top of the second rotating rod to rotate, so that the docking ring rotates stably along the docking groove. At the same time, the rotation of the first storage tray causes the guide roller to rotate in the clearance groove, which further improves the stability of the rotation of the first storage tray. Starting the constant temperature chamber body can facilitate uniform and constant temperature heating of biological products in the first storage tray, thereby improving the quality of storage and placement of biological products.

[0015] 2. This utility model, through its assembly mechanism, presses two arc-shaped limiting plates, causing them to slide along the movable groove and compress the central return spring. This moves the second storage tray, aligning the slot with the top of the support column. Lowering the second storage tray allows the top of the support column to insert into the slot, releasing the arc-shaped limiting plates. Under the action of the return spring, one end of the arc-shaped limiting plates is inserted into the slot for positioning, allowing the second storage tray to be installed above the first storage tray. This facilitates the layered and categorized storage of different types of biological products. Attached Figure Description

The uniform heating mechanism 4 includes a base 41 fixedly installed inside the constant temperature chamber body 1, a drive motor 43 fixedly connected inside the base 41, a first rotating rod 44 fixedly connected to the output shaft of the drive motor 43 through a coupling, a first bevel gear 45 fixedly connected to one end of the first rotating rod 44, a second bevel gear 46 movably connected to the outer wall of the first bevel gear 45, a second rotating rod 47 fixedly connected to the inner wall of the second bevel gear 46, and a first storage tray 48 fixedly connected to the top end of the second rotating rod 47.

[0025] The base 41 has a docking groove 42 inside. The bottom of the first storage tray 48 is fixedly connected to a docking ring 49. The docking ring 49 is located in the docking groove 42. The docking ring 49 and the base 41 form a rotating structure through the docking groove 42, which can make the docking ring 49 rotate along the docking groove 42, thereby improving the stability of the rotation of the first storage tray 48.

[0026] The first storage tray 48 has an clearance groove 5 inside, and a bracket 7 is fixedly connected to the top of the base 41. A movable shaft 8 is installed inside the bracket 7, and a guide roller 9 is installed on the outer wall of the movable shaft 8.

[0027] The guide roller 9 forms a rotating structure with the bracket 7 via the movable shaft 8. The guide roller 9 is movably connected to the first storage tray 48 via the clearance groove 5, which can cause the first storage tray 48 to rotate and drive the guide roller 9 to slide along the clearance groove 5, thereby causing the guide roller 9 to rotate.

[0028] The first bevel gear 45 forms a rotating structure with the base 41 via the first rotating rod 44. The first bevel gear 45 is meshed with the second bevel gear 46. The second bevel gear 46 forms a rotating structure with the base 41 via the second rotating rod 47. The first storage tray 48 forms a rotating structure with the base 41 via the second rotating rod 47, which can make the first bevel gear 45 rotate and drive the second bevel gear 46 to rotate.

[0029] An assembly mechanism 6 is fixedly connected to the top of the first storage tray 48. The assembly mechanism 6 includes a support column 61 fixedly installed on the top of the first storage tray 48. A slot 62 is opened inside the support column 61. A second storage tray 63 is installed on the outer wall of the support column 61. A slot 64 is opened inside the second storage tray 63. A movable groove 65 is opened on the inner side wall of the slot 64. An arc-shaped limiting plate 66 is movably connected inside the movable groove 65. A return spring 67 is fixedly connected to the outer wall of the arc-shaped limiting plate 66.

[0030] The support column 61 is engaged with the second storage tray 63 via the slot 64. The arc-shaped limiting plate 66 forms a sliding structure with the second storage tray 63 via the movable groove 65. The arc-shaped limiting plate 66 is engaged with the support column 61 via the slot 62. The arc-shaped limiting plate 66 is symmetrically arranged around the central axis of the second storage tray 63, which facilitates the installation of the second storage tray 63, thereby enabling the layered storage and placement of biological products.

[0031] Working principle:

[0032] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 By placing the biological product in the first storage tray 48, closing the door 3, and starting the drive motor 43, the first rotating rod 44 can be rotated, driving the first bevel gear 45 to rotate. Since the first bevel gear 45 is meshed with the second bevel gear 46, the second bevel gear 46 can be rotated, driving the first storage tray 48, which is fixedly connected to the top of the second rotating rod 47, to rotate. This causes the docking ring 49 to rotate stably along the docking groove 42. Since the guide roller 9 is in contact with the inner wall of the clearance groove 5, the first storage tray 48 can rotate while the guide roller 9 rotates within the clearance groove 5, further improving the stability of the rotation of the first storage tray 48. Starting the constant temperature chamber body 1 allows for constant temperature heating of the biological product in the first storage tray 48.

[0033] according to Figure 1 , Figure 4 and Figure 6 By pressing the two arc-shaped limiting plates 66, the arc-shaped limiting plates 66 slide along the movable groove 65 and squeeze the middle reset spring 67, moving the second storage tray 63 so that the slot 64 aligns with the top of the support column 61. Moving the second storage tray 63 down allows the top of the support column 61 to be inserted into the slot 64, releasing the arc-shaped limiting plates 66. Under the action of the reset spring 67, the two arc-shaped limiting plates 66 can slide back along the movable groove 65, allowing one end of the arc-shaped limiting plates 66 to be inserted into the slot 62 for limiting, so that the second storage tray 63 is installed above the first storage tray 48.
