Description

Technical Field

[0001] This utility model relates to the field of low-temperature storage box technology, and in particular to a low-temperature storage box with visualized internal temperature. Background Technology

[0002] A cryogenic storage box is a device that can preserve items at low temperatures. When using a cryogenic storage box, the items that need to be preserved at low temperatures are placed inside the main body of the storage box, and then the connecting door is closed. Because the display screen and the temperature sensor installed inside the main body of the storage box are connected together by a connecting wire, the temperature inside the storage box can be displayed on the display screen, thus making the temperature inside the storage box visible.

[0003] The inventors discovered in their daily work that the cryogenic storage box still has at least the following problems: When using the cryogenic storage box, the items that need to be stored at low temperatures are placed inside the main body of the box, and then the connecting door is closed. Because the display screen and the temperature sensor inside the main body of the box are connected together by a connecting wire, the temperature inside the box can be displayed on the screen, thus making the temperature inside the box visible. However, in actual use, when placing items inside the storage box, the connecting door needs to be kept open when taking them out or placing them in one by one, which will affect the temperature inside the box to some extent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-temperature storage box with visualized internal temperature.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-temperature storage box with visualized internal temperature, comprising a storage box body, a connecting door provided on one side of the storage box body, a display screen installed on one side of the storage box body, a connecting device provided inside the storage box body, a limiting device provided on the top of the storage box body, and the connecting device including a sliding frame, the sliding frame being slidably connected to the inner wall of the storage box body.

[0006] The effect achieved by the above components is that when using the connecting device, when placing multiple items inside the main body of the storage box, the multiple items are first placed inside the sliding frame, and then the sliding frame is directly slid into the main body of the storage box. This can, to a certain extent, prevent the connecting door from being opened for a long time.

[0007] Preferably, a support block is fixedly connected to one side of the inner wall of the storage box body, a rectangular groove is opened on one side of the sliding frame, the support block slides through the rectangular groove, a rotating rod is rotatably inserted on one side of the support block, and a rotating block is fixedly connected to the end of the rotating rod away from the support block.

[0008] The effect achieved by the above components is as follows: during the process of sliding the sliding frame to the inner wall of the storage box body, the rotating block and the support block are on the same plane, so that the rotating block and the support block pass through the rectangular groove. After the support block passes through the rectangular groove, the rotating block is manually controlled to drive the rotating rod to rotate, so that the support block and the rotating block are perpendicular to each other, thereby confining the sliding frame inside the storage box body.

[0009] Preferably, a first damping rod is uniformly fixedly connected to the side of the rotating block near the rotating rod, a rubber plate is fixedly connected to the end of the first damping rod near the support block, a first spring is sleeved on the surface of the first damping rod, one end of the first spring is fixedly connected to one side of the rotating block, and the end of the first spring near the first damping rod is fixedly connected to one side of the rubber plate.

[0010] The effect achieved by the above components is that the rubber plate is pressed towards the rotating rod by the first spring, thereby pressing the rubber plate against one side of the inner wall of the sliding frame, thus keeping the support block and the rotating block perpendicular.

[0011] Preferably, the inner wall of the storage box body is uniformly and fixedly connected with protrusions.

[0012] The effect achieved by the above components is that after the sliding frame is placed inside the main body of the storage box, the protrusion is pressed against the surface of the main body of the storage box. This reduces the contact area between the inner wall of the storage box and the sliding frame to a certain extent, thus preventing the sliding frame from being frozen together with the main body of the storage box over a large area.

[0013] Preferably, the limiting device includes a rectangular frame, which is disposed on the side of the storage box body where the display screen is installed, and a locking strip is slidably connected to the inner wall of the rectangular frame.

[0014] The effect achieved by the above components is that when the limiting device is used, after the connecting door is closed, the locking strip is set on the side of the connecting door away from the main body of the storage box, which makes it easy to restrict the connecting door to one side of the main body of the storage box.

[0015] Preferably, a second damping rod is fixedly connected to the top of the inner wall of the rectangular frame, the bottom of the second damping rod is fixedly connected to the top of the locking strip, a second spring is sleeved on the surface of the second damping rod, one end of the second spring is fixedly connected to the top of the inner wall of the rectangular frame, and the end of the second spring near the second damping rod is fixedly connected to the top of the locking strip.

[0016] The effect achieved by the above components is as follows: when the connecting door is close to the main body of the storage box, the connecting door presses the inclined surface of the locking strip, thereby pressing the locking strip into the interior of the rectangular frame. When the connecting door is set on one side of the main body of the storage box, the second spring presses the locking strip, thereby pressing the locking strip against one side of the connecting door.

[0017] Preferably, a fixed frame is fixedly connected to the top of the rectangular frame, and a movable plate is slidably connected to the inner wall of the fixed frame at the end away from the rectangular frame. A threaded rod is rotatably inserted into one side of the inner wall of the fixed frame, and the threaded rod is threadedly inserted into one side of the movable plate.

[0018] The effect achieved by the above components is as follows: the fixed frame is fitted onto the top of the storage box body, and then the threaded rod is manually controlled to rotate, thereby causing the moving plate to be pressed against one side of the storage box body, which makes it easier to set the rectangular frame on one side of the storage box body.

[0019] Preferably, a slot is provided on one side of the inclined surface of the slotting strip, and a cylinder is rotatably inserted into the inner wall of the slotting groove.

[0020] The effect achieved by the above components is that when the connecting door presses against the inclined surface of the locking strip, the cylinder is driven to rotate, thereby allowing the connecting door to press well against one side of the locking strip.

[0021] In this invention, by setting a connecting device, when using the connecting device to place multiple items inside the main body of the storage box, the multiple items are first placed inside the sliding frame, and then the sliding frame is directly slid into the main body of the storage box. This can, to a certain extent, prevent the connecting door from being opened for a long time. Attached Figure Description

[0027] Example 1, such as Figure 1-4 As shown, a cryogenic storage box with internal temperature visualization is provided. A connecting door 2 is provided on one side of the storage box body 1, a display screen 3 is installed on one side of the storage box body 1, a connecting device 4 is provided inside the storage box body 1, and a limit device 5 is provided on the top of the storage box body 1. When using the cryogenic storage box, the items that need to be stored at low temperature are placed inside the storage box body 1, and then the connecting door 2 is closed. Because the display screen 3 and the temperature sensor provided inside the storage box body 1 are connected together by a connecting wire, the internal temperature of the storage box can be displayed on the display screen 3, thus making the internal temperature of the storage box visible.

[0028] Reference Figure 2 and Figure 3The connecting device 4 includes a sliding frame 401, which is slidably connected to the inner wall of the storage box body 1. When using the connecting device 4, if multiple items are placed inside the storage box body 1, the items are first placed inside the sliding frame 401, and then the sliding frame 401 is slid directly into the storage box body 1. This can, to some extent, prevent the connecting door 2 from being opened for a long time. A support block 403 is fixedly connected to one side of the inner wall of the storage box body 1. A rectangular groove 402 is opened on one side of the sliding frame 401, and the support block 403 slides through the rectangular groove 402. A rotating rod 404 is rotatably inserted into one side of the support block 403 in the groove 402. A rotating block 405 is fixedly connected to the end of the rotating rod 404 away from the support block 403. During the process of sliding the sliding frame 401 to the inner wall of the storage box body 1, the rotating block 405 and the support block 403 are on the same plane, allowing the rotating block 405 and the support block 403 to pass through the rectangular groove 402. After the support block 403 passes through the rectangular groove 402, the rotating block 405 is manually controlled to drive the rotating rod 404 to rotate, thereby making the support block 403 and the rotating block 405 perpendicular to each other. The sliding frame 401 is confined inside the main body 1 of the storage box. A first damping rod 406 is evenly fixedly connected to the side of the rotating block 405 near the rotating rod 404. A rubber plate 408 is fixedly connected to one end of the first damping rod 406 near the support block 403. A first spring 407 is sleeved on the surface of the first damping rod 406. One end of the first spring 407 is fixedly connected to one side of the rotating block 405, and the end of the first spring 407 near the first damping rod 406 is fixedly connected to one side of the rubber plate 408. The first spring 407 then... The rubber plate 408 is pressed in a certain direction, which causes the rubber plate 408 to be pressed against one side of the inner wall of the sliding frame 401, thereby keeping the support block 403 and the rotating block 405 perpendicular. The inner wall of the storage box body 1 is uniformly fixed with protrusions 409. After the sliding frame 401 is placed inside the storage box body 1, the protrusions 409 are pressed against the surface of the storage box body 1. This reduces the contact area between the inner wall of the storage box body 1 and the sliding frame 401 to a certain extent, thus avoiding the sliding frame 401 and the storage box body 1 from being frozen together over a large area.

[0029] Reference Figure 4The limiting device 5 includes a rectangular frame 501, which is located on the side of the storage box body 1 where the display screen 3 is installed. A locking strip 504 is slidably connected to the inner wall of the rectangular frame 501. When using the limiting device 5, after the connecting door 2 is closed, the locking strip 504 is located on the side of the connecting door 2 away from the storage box body 1, thus confining the connecting door 2 to one side of the storage box body 1. A second damping rod 502 is fixedly connected to the top of the inner wall of the rectangular frame 501. The bottom and the top of the locking strip 504 are fixedly connected. A second spring 503 is sleeved on the surface of the second damping rod 502. One end of the second spring 503 is fixedly connected to the top of the inner wall of the rectangular frame 501. The end of the second spring 503 near the second damping rod 502 is fixedly connected to the top of the locking strip 504. When the connecting door 2 is close to the storage box body 1, the connecting door 2 presses the inclined surface of the locking strip 504, thereby causing the locking strip 504 to be pressed into the interior of the rectangular frame 501. When the device is positioned on one side of the main body 1 of the storage box, the second spring 503 presses the locking strip 504, thereby pressing the locking strip 504 against one side of the connecting door 2. A fixed frame 507 is fixedly connected to the top of the rectangular frame 501. A movable plate 508 is slidably connected to the inner wall of the fixed frame 507 away from the rectangular frame 501. A threaded rod 509 is rotatably inserted into one side of the inner wall of the fixed frame 507. The threaded rod 509 is threadedly inserted into one side of the movable plate 508, thus fitting the fixed frame 507 onto the main body of the storage box. The top of 1 is then manually controlled to rotate the threaded rod 509, which causes the moving plate 508 to press against one side of the storage box body 1. This makes it easier to set the rectangular frame 501 on one side of the storage box body 1. A slot 505 is provided on one side of the inclined surface of the slot strip 504. A cylinder 506 is inserted into the inner wall of the slot 505. When the connecting door 2 presses against the inclined surface of the slot strip 504, the cylinder 506 is driven to rotate, which allows the connecting door 2 to press well against one side of the slot strip 504.

[0030] Working principle: When using the cryogenic storage box, place the items requiring cryogenic storage inside the main body 1 of the box, and then close the connecting door 2. Because the display screen 3 and the temperature sensor installed inside the main body 1 of the box are connected by a connecting cable, the internal temperature of the box can be displayed on the display screen 3, thus making the internal temperature of the box visible. When using the connecting device 4, when placing multiple items inside the main body 1 of the box, first place the multiple items inside the sliding frame 401, and then slide the sliding frame 401 directly into the main body 1 of the box. During the process of moving the inner wall of body 1, the rotating block 405 and the support block 403 are on the same plane, so that the rotating block 405 and the support block 403 pass through the rectangular groove 402. After the support block 403 passes through the rectangular groove 402, the rotating block 405 is manually controlled to drive the rotating rod 404 to rotate, so that the support block 403 and the rotating block 405 are perpendicular to each other. The first spring 407 presses the rubber plate 408 towards the rotating rod 404, so that the rubber plate 408 is pressed against one side of the inner wall of the sliding frame 401, so that the support block 403 and the rotating block 405 remain perpendicular, thus restricting the sliding frame 401 within the main body of the storage box. Inside the main body 1, this can, to some extent, prevent the connecting door 2 from being open for extended periods. After the sliding frame 401 is placed inside the main body 1, the protrusion 409 presses against the main body 1, thus reducing the contact area between the inner wall of the main body 1 and the sliding frame 401. This also helps prevent the sliding frame 401 from being frozen together with the main body 1 over a large area. When using the limiting device 5, the fixing frame 507 is fitted onto the top of the main body 1, and then the threaded rod 509 is manually rotated, causing the moving plate 508 to press against one side of the main body 1. This facilitates the placement of the rectangular frame. 501 is set on one side of the storage box body 1. When the connecting door 2 is close to one side of the storage box body 1, the connecting door 2 presses the inclined surface of the locking strip 504, thereby pressing the locking strip 504 into the interior of the rectangular frame 501. When the connecting door 2 is set on one side of the storage box body 1, the second spring 503 presses the locking strip 504, thereby pressing the locking strip 504 against one side of the connecting door 2. When the connecting door 2 presses the inclined surface of the locking strip 504, the cylinder 506 is driven to rotate, thereby allowing the connecting door 2 to be well pressed against one side of the locking strip 504, which makes it easier to restrict the connecting door 2 to one side of the storage box body 1.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
