Description

Technical Field

[0001] This utility model relates to the field of biochemical incubator technology, specifically to a compartmentalized biochemical incubator. Background Technology

[0002] Biochemical incubators feature a bidirectional temperature control system for both cooling and heating, making them essential experimental equipment in laboratories of research institutions, universities, production units, and departments in fields such as biology, genetic engineering, medicine, public health and disease control, environmental protection, agriculture, forestry, and animal husbandry. They are widely used in low-temperature constant-temperature experiments, culture experiments, and environmental experiments. The biochemical incubator controller circuit consists of a temperature sensor, a voltage comparator, and a control execution circuit. Biochemical incubators are also widely used in research institutions, universities, and production departments in environmental protection, public health and disease control, drug testing, agriculture, animal husbandry, and aquaculture. They are specialized constant-temperature equipment for water analysis and BOD determination, the cultivation and preservation of bacteria, fungi, and microorganisms, plant cultivation, and breeding experiments.

[0003] An existing patent (authorization announcement number: CN222119191U) discloses a partitioned biochemical incubator. Through the structural cooperation of the guiding mechanism, the distance between adjacent support plates can be conveniently adjusted by rotating the transmission screw. This allows for adjustment of the space inside the biochemical incubator, enabling the support plates to adapt to the carrying requirements of culture dishes of different heights, greatly improving the overall applicability.

[0004] However, the above technical solution still has certain defects. The support plate and the transmission seat are fixedly connected, which means that users need to put their hands into the biochemical incubator to operate when picking up or placing culture dishes. This makes it inconvenient for users to pick up or place some culture dishes that are large or small, thus affecting the overall applicability. At the same time, the support plate is also inconvenient to disassemble for cleaning or replacement. Utility Model Content

[0005] The purpose of this invention is to provide a compartmentalized biochemical incubator to solve the problem that existing support plates are inconvenient for placing culture dishes.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A compartmentalized biochemical incubator includes a main body of the biochemical incubator, a sealed door on the front side of the main body of the biochemical incubator, and transmission boxes on both sides of the main body of the biochemical incubator. The transmission boxes are equipped with transmission adjustment components, which include a connecting plate and a support plate. The support plate and the connecting plate are slidably connected by a moving component.

[0008] The movable component includes a U-shaped frame disposed on one side of the support plate and slidingly engaged with the connecting plate. The front top of both the U-shaped frame and the connecting plate is provided with a fixing hole. The front top of the U-shaped frame is provided with a fixing sleeve corresponding to the fixing hole. A fixing rod matching the fixing hole is provided longitudinally inside the fixing sleeve. A fixing ring is provided on the outer wall of the fixing rod located inside the fixing sleeve. A second spring is connected between the top of the fixing ring and the top of the inner cavity of the fixing sleeve. The bottom end of the fixing rod is inserted into the fixing hole on the connecting plate, and the top end of the fixing rod extends to the outside of the fixing sleeve.

[0009] Furthermore, the aforementioned second spring is sleeved on the outer wall of the fixed rod.

[0010] Furthermore, the top and bottom of the aforementioned connecting plate are each provided with a number of ball bearings that abut against the inner side of the U-shaped frame at equal intervals.

[0011] Furthermore, a pull ring is provided at the top of the aforementioned fixing rod.

[0012] Furthermore, the aforementioned transmission adjustment assembly also includes rotating shafts that are respectively horizontally arranged on the inner walls of the bottom ends of the two sets of transmission boxes. The outer walls of both ends of the rotating shafts are respectively provided with transmission bevel gears, and the transmission bevel gears mesh with driven bevel gears. The top center of the driven bevel gear is connected to a threaded screw. The top end of the threaded screw is rotatably connected to the top of the corresponding transmission box cavity through a bearing. The outer walls of the two threaded screws in the transmission box are threaded with transmission shafts. One side of the connecting plate is sleeved on the corresponding transmission shaft through a bearing. A locking assembly for limiting the rotation of the transmission shaft is provided between the top of the connecting plate and the transmission shaft.

[0013] Both sets of rotating shafts are equipped with pulleys on the outer wall of their rear ends, and the two sets of pulleys are connected by belt drive. A motor is installed on the front side of one transmission box, and the front end of the corresponding rotating shaft extends out of the transmission box and is connected to the output end of the motor through a coupling.

[0014] Furthermore, the aforementioned engaging assembly includes a support seat vertically disposed on the top of the connecting plate, with insert rods passing through both ends of the support seat, and pull plates disposed near the end of the two sets of insert rods near the bearing plate. First springs are connected between the pull plates and both ends of the support seat, and the two sets of first springs are sleeved on the outer wall of the corresponding insert rods.

[0015] Furthermore, the top of the aforementioned drive shaft is provided with a locking disc, and multiple equidistant limiting grooves are opened on the outer side of the locking disc, with the insertion rod inserted into the limiting groove.

[0016] Furthermore, a control panel is provided on the front side of the aforementioned set of transmission boxes, and the control panel is electrically connected to the motor.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model designs a movable component that can be pulled to disengage from the fixed insertion hole on the connecting plate, thereby releasing the restriction on the support plate and the U-shaped frame. Then, the user can pull out the support plate, making it easier for the user to place some large or small petri dishes on the support plate, improving work efficiency and device practicality; the pull ring at the top of the fixed rod is easy for the user to pull.

[0019] 2. This utility model, through the design of a locking assembly, allows the insertion rod on the locking assembly to be inserted into the limiting groove in the locking disc on the corresponding drive shaft. When the drive shaft, restricted by the locking assembly, rotates the threaded screw, it can drive the corresponding connecting plate and the bearing plate to move up and down on the outer wall of the threaded screw. When the locking assembly does not restrict the rotation of the drive shaft, the drive shaft can rotate with the threaded screw, thereby keeping the bearing plate that does not need adjustment in place. This allows adjustment of the distance between adjacent bearing plates, thereby adjusting the space inside the biochemical incubator and enabling the bearing plate to adapt to the bearing requirements of culture dishes of different heights, greatly improving the overall applicability.

Detailed Implementation

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] like Figures 1 to 6 As shown, an embodiment of this utility model provides a partitioned biochemical incubator, including a biochemical incubator body 100. A sealing door 110 is connected to the front side of the biochemical incubator body 100 via a hinge. Transmission boxes 120 are provided on both sides of the biochemical incubator body 100. The biochemical incubator body 100 has openings on both sides, and the transmission box 120 also has the same opening on the side near the biochemical incubator body 100. The transmission box 120 can completely cover and close the openings on both sides of the biochemical incubator body 100. A transmission adjustment assembly 200 is provided inside the transmission box 120. The transmission adjustment assembly 200 includes a connecting plate 260 and a support plate 270. The support plate 270 and the connecting plate 260 are slidably connected by a moving assembly 400.

[0029] The movable component 400 includes a U-shaped frame 410 disposed on one side of the support plate 270 and slidably engaged with the connecting plate 260. The U-shaped frame 410 is bolted to the support plate 270. Both the U-shaped frame 410 and the connecting plate 260 have fixing holes 430 at their front ends. The end of the U-shaped frame 410 and the connecting plate 260 closest to the sealing door 110 is the front end, and the other end is the rear end. A fixing sleeve 440 corresponding to the fixing hole 430 is provided at the front end of the U-shaped frame 410. A fixing rod 450 matching the fixing hole 430 is longitudinally arranged inside the fixing sleeve 440. A fixing ring 460 is provided on the outer wall of the fixing rod 450, which is located near the top side of the U-shaped frame 410. A second spring 470 is connected between the top of the fixing ring 460 and the top of the inner cavity of the fixing sleeve 440, and the second spring 470 is sleeved on the outer wall of the fixing rod 450. The bottom end of the fixing rod 450 is inserted into the fixing hole 430 on the connecting plate 260, and the top end of the fixing rod 450 extends to the outside of the fixing sleeve 440. A through hole is provided on the top of the fixing sleeve 440 to facilitate the extension of the fixing rod 450. A pull ring 480 is provided on the top end of the fixing rod 450, which facilitates the real-time pulling of the fixing rod 450.

[0030] When it is necessary to store petri dishes, the user opens the sealing door 110 and then pulls the pull ring 480 above the U-shaped frame 410, causing the fixing rod 450 to disengage from the fixing insertion hole 430 on the connecting plate 260, thereby releasing the U-shaped frame 410 from limiting the connecting plate 260 and the support plate 270. During this process, as the fixing rod 450 moves upward, it will cause the fixing ring 460 to compress the second spring 470, at which time the second spring 470 has elastic potential energy. Then the user pulls out the support plate 270, making it easier for the user to place some petri dishes of larger or smaller volume on the support plate 270, improving work efficiency and device practicality. After the user has finished placing the petri dishes, push the support plate 270 back to its original position, release the pull ring 480, and the fixing rod 450, under the action of the elastic potential energy of the second spring 470, re-inserts into the fixing insertion hole 430 on the connecting plate 260 to complete the fixation of the support plate 270.

[0031] like Figure 4 As shown, in another embodiment of the present invention, in order to reduce the friction between the connecting plate 260 and the U-shaped frame 410, the top and bottom of the connecting plate 260 are provided with a plurality of ball bearings 420 that abut against the inner side of the U-shaped frame 410 at equal intervals.

[0032] like Figures 1 to 3As shown, the transmission adjustment assembly 200 also includes rotating shafts 210 respectively horizontally arranged on the inner walls of the bottom ends of the two sets of transmission boxes 120. Transmission bevel gears 220 are respectively arranged on the outer walls of both ends of the rotating shafts 210, and the transmission bevel gears 220 mesh with driven bevel gears 230. The driven bevel gears 230 are located above the transmission bevel gears 220, and a threaded screw 240 is connected to the center of the top of the driven bevel gear 230. The top end of the threaded screw 240 is rotatably connected to the top of the corresponding inner cavity of the transmission box 120 via a bearing. The outer walls of the two threaded screws 240 inside the transmission box 120 are both threadedly connected to... The drive shaft 250 and the connecting plate 260 are connected to the corresponding drive shaft 250 by bearings on one side. The top of the connecting plate 260 and the drive shaft 250 are provided with a locking assembly 300 for limiting the rotation of the drive shaft 250. The locking assembly 300 is used to release the drive shaft 250 according to the usage requirements, so that the support plate 270 that does not need to be adjusted stays in place. The support plate 270 that needs to be adjusted moves up and down under the drive of the connecting plate 260, thereby adjusting the distance between adjacent support plates 270, thereby adjusting the space inside the biochemical incubator body 100.

[0033] Both sets of rotating shafts 210 have pulleys on their rear outer walls. The end of the rotating shaft 210 closest to the sealing door 110 is the front end, and the opposite end is the rear end. The two sets of pulleys are connected by a belt 290. A motor 280 is located on the front side of the transmission box 120. The front end of one set of rotating shafts 210 extends outside the transmission box 120 and is connected to the output end of the motor 280 via a coupling. To achieve intelligent control, a control panel 130 is located on the front side of one set of transmission boxes 120, and the control panel 130 is electrically connected to the motor 280.

[0034] Adjust the distance between the upper and lower sets of support plates 270 as needed. Start the motor 280 via the control panel 130. The output of the motor 280 drives a set of rotating shafts 210 to rotate. Utilizing the belt 290, the two sets of rotating shafts 210 rotate synchronously, thereby driving the transmission bevel gear 220 on the rotating shaft 210 to rotate. This, in turn, drives the driven bevel gear 230 meshing with it to rotate, which in turn drives the threaded screw 240 to rotate. This causes the transmission shaft 250, no longer restricted by the locking assembly 300, to rotate along with the threaded screw 240, thus preventing... The threaded screw 240 moves up and down on its outer wall, keeping the support plate 270, which does not require adjustment, in place. The drive shaft 250, which is restricted by the locking assembly 300, can drive the corresponding connecting plate 260 and support plate 270 to move up and down on the outer wall of the threaded screw 240 when the threaded screw 240 rotates. This adjusts the distance between adjacent support plates 270, thereby adjusting the space inside the biochemical incubator body 100. This allows the support plate 270 to adapt to the carrying requirements of culture dishes of different heights, greatly improving the overall applicability.

[0035] like Figure 2 , Figure 4 as well as Figure 5 As shown, the engaging assembly 300 includes a support base 310 vertically disposed on the top of the connecting plate 260. Insert rods 320 are respectively provided through both ends of the support base 310. Pull plates 340 are provided at the ends of the two sets of insert rods 320 near the bearing plate 270. First springs 350 are respectively connected between the pull plates 340 and the two ends of the support base 310. The two sets of first springs 350 are sleeved on the outer wall of the corresponding insert rods 320. A locking disc 330 is provided at the top of the drive shaft 250. Multiple equidistant limiting grooves 331 are opened on the outer side of the locking disc 330, and the insert rods 320 are inserted into the limiting grooves 331.

[0036] When it is necessary to adjust the distance between adjacent bearing plates 270, pull the pull plates 340 on both sides of the bearing plate 270, causing the insertion rod 320 to disengage from the limiting groove 331 on the locking plate 330. At this time, the pull plate 340 causes the first spring 350 to stretch, and the transmission shaft 250 is no longer restricted by the locking component 300. Meanwhile, the adjacent transmission shaft 250 is restricted by the locking component 300. The distance between adjacent bearing plates 270 is adjusted in conjunction with the transmission adjustment component 200. After the adjustment is completed, release the pull plate 340. Under the action of the elastic potential energy of the first spring 350, the insertion rod 320 is re-inserted into the limiting groove 331 on the locking plate 330, thereby limiting the transmission shaft 250.

[0037] In use, the user opens the sealing door 110, then pulls the pull ring 480 above the U-shaped frame 410, causing the fixing rod 450 to disengage from the fixing insertion hole 430 on the connecting plate 260, thereby releasing the restriction on the connecting plate 260 and the support plate 270. Then the user pulls out the support plate 270, making it easier for the user to place some larger or smaller petri dishes on the support plate 270, improving work efficiency and the practicality of the device.

[0038] According to usage requirements, adjust the distance between the upper and lower sets of support plates 270. Start the motor 280 through the control panel 130. The output end of the motor 280 drives the rotating shaft 210 to rotate, thereby driving the transmission bevel gear 220 on the rotating shaft 210 to rotate, which in turn drives the driven bevel gear 230 meshing with it to rotate, thereby driving the threaded screw 240 to rotate. This causes the transmission shaft 250, which is no longer restricted by the locking component 300, to rotate with the threaded screw 240 and thus will not move up and down on the outer wall of the threaded screw 240. This allows the support plates 270 that do not need adjustment to remain in place. The transmission shaft 250, which is restricted by the locking component 300, can drive the corresponding connected plate 260 and support plate 270 to move up and down on the outer wall of the threaded screw 240 when the threaded screw 240 rotates. This adjusts the distance between adjacent support plates 270, thereby adjusting the space inside the biochemical incubator body 100. This allows the support plates 270 to adapt to the carrying requirements of culture dishes of different heights, greatly improving the overall applicability.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
