[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 7 , in the illustration, a foam box heat preservation performance test device includes a detection table 1 and an incubator 2. The incubator 2 includes a box body 21 and a main cover body 22. One side of the main cover body 22 is rotatably connected to the box body 21 through a rotating shaft 23. A plurality of partition boards 24 are fixedly connected inside the box body 21. The partition boards 24 divide the interior of the box body 21 into a plurality of independent storage cavities. Temperature sensors 8 are placed in each independent storage cavity. A plurality of through grooves 25 are formed on the upper surface of the main cover body 22. The through grooves 25 are arranged in one-to-one correspondence with the storage cavities, and an opening and closing assembly 7 is arranged on the surface of each through groove 25. The opening and closing assembly 7 is used to control the opening and closing of the through groove 25; A clamping assembly 3 for fixing the incubator 2 is arranged on the upper surface of the horizontal part of the detection table 1. Control assemblies 4 are arranged on the vertical parts of the detection table 1. The control assemblies 4 are used to control the movement of the opening and closing assembly 7 to open or close the through groove 25.

[0019] Specifically, temperature sensors are mainly divided into types such as capacitive, resistive, fiber optic, thermocouple, thermal resistance, and metal-semiconductor structures. The temperature sensor 8 in this embodiment uses a resistive temperature sensor, which detects temperature by utilizing the characteristic that the resistance value of the material changes with temperature; the temperature sensor 8 in this embodiment is an active sensor with its own power supply, capable of actively generating and providing signal output, that is, it can automatically send the detected data to the background computer, and the detection personnel can obtain the detected data by checking the computer. Here, the model of the temperature sensor 8 is not required, and the number of temperature sensors 8 is set according to the number of storage cavities in the box body 21. During detection, each temperature sensor 8 can be placed inside the corresponding storage cavity.

[0020] In this embodiment, when it is necessary to detect the heat preservation performance of the incubator 2, the incubator 2 is placed on the surface of the detection table 1 and fixed by the clamping assembly 3, and then the control assembly 4 randomly drives one group of the opening and closing assemblies 7 to move, simulating the opening and closing actions of the opening and closing assembly 7 when taking out the sample, and using the temperature sensor 8 to detect the temperature in each storage cavity after this operation, so as to detect the heat preservation performance of the incubator 2.

[0021] In addition, the opening and closing times of the opening and closing assembly 7 can be randomly set to ensure the reliability and objectivity of the detection results.

[0022] Further, the opening and closing assembly 7 includes a sub-cover plate 72 slidably installed inside the through groove 25. One end of the sub-cover plate 72 penetrates to the outside of the main cover body 22, and the side of the sub-cover plate 72 located outside the main cover body 22 is set to be L-shaped. A guide rod 74 is fixedly connected to the side wall of the vertical part of the L-shaped sub-cover plate 72. The other end of the guide rod 74 is fixedly connected to a connecting block 71. The connecting block 71 is fixedly connected to the sub-cover plate 72. And a vertical plate 76 is fixedly connected to the position on the upper surface of the main cover body 22 between the vertical part of the L-shaped sub-cover plate 72 and the connecting block 71. The guide rod 74 penetrates through the vertical plate 76 and is slidably matched with it. And a telescopic spring 75 is sleeved on the outer surface of the guide rod 74. One end of the telescopic spring 75 is fixedly connected to the vertical plate 76, and the other end of the telescopic spring 75 is fixedly connected to the connecting block 71. Connecting grooves 73 are opened on the upper surface of the vertical part of the L-shaped sub-cover plate 72, and the connecting end of the control assembly 4 can be moved into or out of the connecting groove 73.

[0023] Further, it further includes a horizontal moving assembly 5. The horizontal moving assembly 5 includes a chute 53 opened on the vertical part of the detection table 1. The chute 53 is horizontally arranged, and a lead screw 51 is rotatably connected inside the chute 53. A ball seat 52 is sleeved on the outer surface of the lead screw 51. A motor 54 is fixedly installed on the outer surface of the detection table 1. The output shaft of the motor 54 is fixedly connected to one end of the lead screw 51. The control assembly 4 is arranged on the ball seat 52.

[0024] Specifically, the ball screw is an existing transmission component, whose main function is to convert rotational motion into linear motion, which will not be elaborated here. During actual use, the motor 54 needs to be connected to an external power supply, and the motor 54 is driven to rotate forward and backward, so that the ball seat 52 moves back and forth along the lead screw 51, thereby driving the control component 4 to move.

[0025] Furthermore, the control component 4 includes an electromagnet 41 fixedly installed on the outer surface of the vertical part of the detection table 1. A sliding sleeve 42 is sleeved on the outer surface of the ball seat 52. The sliding sleeve 42 can move relative to the ball seat 52, and the moving direction of the sliding sleeve 42 is perpendicular to the lead screw 51. A connecting spring 46 is fixedly connected between the sliding sleeve 42 and the ball seat 52. One side of the upper surface of the sliding sleeve 42 is fixedly connected with a magnetic block 45. The upper surface of the sliding sleeve 42 is also fixedly connected with an electric push rod 43. The telescopic end of the electric push rod 43 is fixedly connected with a connecting plate 44 adapted to the connecting groove 73. When the connecting spring 46 is in a natural state, the connecting plate 44 is located above the connecting groove 73.

[0026] Furthermore, the electromagnet 41 is energized to attract the magnetic block 45, and the electromagnet 41 is arranged parallel to the sliding groove 53.

[0027] In this embodiment, when it is necessary to drive one set of opening and closing components 7 to move, it is only necessary to use the horizontal moving component 5 to move the connecting plate 44 above the corresponding connecting groove 73, then drive the electric push rod 43 to extend, so that the connecting plate 44 is inserted into the connecting groove 73, and then the power supply of the electromagnet 41 is turned on. The electromagnet 41 attracts the magnetic block 45 to move, thereby driving the sliding sleeve 42, the connecting plate 44 and the corresponding sub-cover plate 72 to move. At this time, the connecting spring 46 and the corresponding telescopic spring 75 are both compressed, and the corresponding storage cavity is opened. After one minute, the power supply of the electromagnet 41 is cut off, and the compressed connecting spring 46 and telescopic spring 75 are reset, which can drive the sliding sleeve 42, the connecting plate 44 and the corresponding sub-cover plate 72 to reset, and the corresponding storage cavity is closed, thereby simulating the opening and closing process of this set of storage cavities; when it is necessary to open again, only repeat the above steps.

[0028] It should be noted that: the switch interfaces of the electromagnet 41, the motor 54, and the electric push rod 43 are all connected to an external power supply through wires. The circuits involved are existing conventional technologies, which will not be elaborated here; in addition, the electromagnet 41, the motor 54, and the electric push rod 43 are all used in conjunction with a PLC. The PLC can control the operation of the electromagnet 41, the motor 54, and the electric push rod 43 through programming.

[0029] It further includes multiple groups of counting components 6 arranged on the vertical part of the detection table 1. The counting components 6 are arranged in one-to-one correspondence with the sub-cover plates 72, and the counting components 6 can record the opening times of the corresponding sub-cover plates 72.

[0030] Further, each counting component 6 includes a moving groove 61 formed on the surface of the vertical part of the detection table 1, and a pressing plate 67 fixedly installed on the lower surface of the sliding sleeve 42. At positions on the outer surface of the detection table 1 above the moving groove 61, first air bags 62 are fixedly connected. A second air bag 63 is arranged at the top of the moving groove 61. A connecting pipe 64 is fixedly and communicatively connected between the first air bag 62 and the second air bag 63. An air suction pipe 65 is fixedly and communicatively connected to the surface of the first air bag 62. One-way valves 66 are fixedly installed on both the connecting pipe 64 and the air suction pipe 65. When the control component 4 drives the sub-cover plate 72 to open, the pressing plate 67 compresses the first air bag 62 corresponding to the sub-cover plate 72.

[0031] In this embodiment, the one-way valve 66 can be any existing type of valve body as long as it can control the pipeline channel. Here, the model of the one-way valve 66 is not required. Among them, the one-way valve 66 on the air suction pipe 65 ensures that the external gas can enter the inside of the first air bag 62 through the air suction pipe 65, and the gas inside the first air bag 62 cannot be discharged through the air suction pipe 65; the one-way valve 66 on the connecting pipe 64 ensures that the gas inside the first air bag 62 can enter the inside of the second air bag 63 through the connecting pipe 64, and the gas inside the second air bag 63 cannot enter the first air bag 62 through the connecting pipe 64.

[0032] Further, exhaust ports are arranged on the surface of the second air bag 63, and detachable rubber plugs are installed inside the exhaust ports.

[0033] In this embodiment, by setting the counting component 6, the opening and closing times of the corresponding opening and closing component 7 can be automatically recorded. Specifically, when the control component 4 drives the opening and closing component 7 to open once, the pressing plate 67 on the sliding sleeve 42 will compress the first air bag 62 corresponding to the opening and closing component 7 once. The gas inside the first air bag 62 is then input into the second air bag 63 through the connecting pipe 64. Therefore, every time the opening and closing component 7 opens, the first air bag 62 transports gas into the second air bag 63 once, and the gas transported by the first air bag 62 each time is the same. Therefore, the opening and closing times of the opening and closing component 7 can be obtained according to the length of the second air bag 63. During actual use, corresponding scales can be set on the surface of the moving groove 61, and the unit length of the scale is the elongation length of the second air bag 63 when the first air bag 62 is compressed once.

[0034] In addition, the rubber plug can actually be threadedly installed at the exhaust port. After the detection is completed, the rubber plug can be unscrewed to discharge the gas inside the second air bag 63.

[0035] Further, the clamping component 3 includes fixing plates 32 fixedly installed on both sides of the detection table 1. Positioning bolts 31 are inserted in the middle of the fixing plates 32. Clamping plates 33 are arranged at the ends of the positioning bolts 31. The positioning bolts 31 are rotatably matched with the clamping plates 33.

[0036] Further, grooves 34 are formed on both sides of the upper surface of the horizontal part of the detection table 1, and sliders adapted to the grooves 34 are provided on the lower surface of the clamping plate 33, and the sliders are slidably installed inside the grooves 34.

[0037] In this embodiment, the incubator 2 is placed between the two clamping plates 33, and the position of the incubator 2 is adjusted so that one set of connecting grooves 73 is aligned with the connecting plate 44, and then the positioning bolt 31 is rotated to make the clamping plate 33 abut against the side wall of the incubator 2, so that the incubator 2 can be fixed.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
