Description

Technical Field

[0001] The present invention relates to the field of temperature and humidity inspection, and particularly to a temperature and humidity field inspection device and method for detecting environmental test equipment. Background Art

[0002] An inspection instrument is an industrial measurement and control instrument that can be used in conjunction with various sensors. After connecting a temperature and humidity sensor to the inspection instrument, it becomes a temperature and humidity inspection instrument, which can be used to calibrate and detect the temperature and humidity fields of environmental test equipment, such as calibrating and detecting the temperature and humidity fields of equipment such as drying ovens, biological incubators, and constant temperature and humidity chambers.

[0003] Chinese Patent Publication No. CN218270886U discloses a fixed temperature and humidity inspection instrument. Through a storage device, it can prevent the situation that when the cable is long, some cables will drag to the ground, resulting in the cables being easily trampled, and thus the cables break, affecting the use of the temperature and humidity sensor.

[0004] However, the technical solutions in the above patent have the following deficiencies:

[0005] When winding the cable around the storage rack, the cable is wound around the storage rack. However, the storage rack is only a single rod-shaped structure, and the length of the cable that can be wound on it is limited.

Detailed implementation manners

[0038] Embodiment 1

[0039] As Figures 1 - 9 shown, a temperature and humidity field inspection device for detecting an environmental test device proposed in this embodiment includes a temperature and humidity field inspection instrument 1 and a cable winding and unwinding mechanism.

[0040] A plurality of channel interfaces 101 are arranged in an array on the top of the temperature and humidity field inspection instrument 1. The temperature and humidity field inspection instrument 1 is connected with a signal transmission cable through the channel interfaces 101, and the signal transmission cable is wound on the cable winding and unwinding mechanism.

[0041] The cable winding mechanism includes an inner rod assembly, an outer rod assembly, a fixed column 8, a threaded knob 9, a mobile platform 10 and a bracket 11. The inner rod assembly and the outer rod assembly are evenly distributed in a circular shape around the fixed column 8, and the multiple groups of inner rod assemblies and the multiple groups of outer rod assemblies are staggered. The inner rod assembly includes an inner rod 2, a connecting rod a3 and a connecting rod b4. Two connecting rods a3 are arranged in parallel. The inner rod 2, the connecting rod a3 and the fixed column 8 form a parallelogram mechanism a. At this time, the inner rod 2 and the fixed column 8 are respectively connected to the two connecting rods a3 for rotation. The inner rod 2 extends outward in the horizontal direction and forms a winding part a, on which the signal transmission cable can be wound. The two ends of the connecting rod b4 are respectively connected to the mobile platform 10 and a connecting rod a3 for rotation. The outer rod assembly includes an outer rod 5, a connecting rod c6 and a connecting rod d7. Two connecting rods c6 are arranged in parallel. The outer rod 5, the connecting rod c6 and the fixed column 8 form a parallelogram mechanism b. At this time, the outer rod 5 and the fixed column 8 are respectively connected to the two connecting rods c6 for rotation. The outer rod 5 extends outward in the horizontal direction and forms a winding portion b, on which a signal transmission cable can be wound. A stopper 51 is provided outward at one end of the outer rod 5 close to the threaded knob 9, which can limit the wound signal transmission cable. The two ends of the connecting rod d7 are respectively rotatably connected to the mobile platform 10 and a connecting rod c6, and the connecting rod c6 and the connecting rod a3 are respectively inclined to the two sides of the fixed column 8 to ensure that the outer rod 5 and the inner rod 2 are in opposite unfolding and folding states. The mobile platform 10 is threadedly connected to the threaded knob 9, and the threaded knob 9 is rotatably set on the fixed column 8. The fixed column 8 is set on the bracket 11, and the bracket 11 is set on the top of the temperature and humidity field inspection instrument 1, so that the signal transmission cable connected at the lower channel interface 101 can be wound around the inner rod 2 and / or the outer rod 5.

[0042] When winding signal transmission cables, there are mainly three winding methods: Figures 10 - 12 The signal transmission cable is only used to schematically illustrate the winding method. In fact, it is not a closed ring as shown in the figure, but has two connection ends, and one connection end is connected to the channel interface 101):

[0043] The first winding method: Figure 10 As shown, when the signal transmission cable is not long, the signal transmission cable is wound around the multiple inner rods 2 distributed inside. At this time, the outer rods 5 outside can be used to limit the position of the signal transmission cable on the inner rods 2. When the signal transmission cable cannot be fully wound around the inner rods 2 alone, the second winding method described below is used for winding.

[0044] The second winding method: Figure 11 As shown, the signal transmission cables are all wound around multiple outer rods 5 distributed outside, and the signal transmission cables are limited by the end stopper 51. When the signal transmission cables cannot be fully wound around the outer rods 5 alone, the following third winding method is used for winding.

[0045] The third winding method: As Figure 12 shown, wind the signal transmission cable around the inner side of the inner rod 2 and around the outer side of the outer rod. At this time, the signal transmission cable can be firmly wound and is not easy to fall off, and the winding length can be longer. In order to further improve the ability to wind the signal transmission cable, the inner rod 2 can be retracted inward, and the outer rod 5 can be expanded outward. At this time, when the signal transmission cable winds around the inner rod 2 and the outer rod 5, the winding length can be longer.

[0046] In this embodiment, the length of the wound signal transmission cable is adaptively adjusted by adjusting the distribution of the inner rod 2 and the outer rod 5, that is, rotate the threaded knob 9 according to the actual length of the signal transmission cable, and wind the signal transmission cable on the inner rod 2 and / or the outer rod 5 by adjusting the distribution of the inner rod 2 and the outer rod 5. When adjusting the distribution of the inner rod 2 and the outer rod 5, rotate the threaded knob 9, and the threaded knob 9 drives the moving platform 10 to move. The moving platform 10 drives the inner rod 2 to move inward (or outward) through the connecting rod b4 and the connecting rod a3, that is, multiple inner rods 2 are retracted (or expanded); the moving platform 10 drives the outer rod 5 to move outward (or inward) through the connecting rod d7 and the connecting rod c6, that is, multiple outer rods 5 are expanded (or retracted). When the outer rod 5 is expanded, the inner rod 2 is retracted; when the outer rod 5 is retracted, the inner rod 2 is expanded, and the expansion and retraction processes are synchronized, and the adjustment operation is very convenient.

[0047] Embodiment 2

[0048] As Figure 2 , Figure 3 , Figure 6 and Figure 7 shown, a temperature and humidity field inspection device for environmental test equipment detection proposed in this embodiment, compared with Embodiment 1, in this embodiment, it further includes an installation shell 12. A plurality of side ears 121 are provided on the side of the installation shell 12, and installation holes are provided on the side ears 121. The installation shell 12 is pre-installed on the environmental test equipment to be detected through the installation holes. An installation space is formed inside the installation shell 12, and a temperature and humidity field inspection instrument 1 can be installed at the installation space. A sliding rod a14 is slidably arranged along the vertical direction at the lower part of the installation space. The top end of the sliding rod a14 is connected with a limiting platform 13, and the bottom end of the sliding rod a14 is connected with a pulling handle 15. An elastic member a16 is connected between the limiting platform 13 and the inner bottom surface of the installation shell 12, and the limiting platform 13 has an inclined upward inclined surface a.

[0049] An installation groove a102 with an opening facing downward is provided on the back of the temperature and humidity field inspection instrument 1. A blocking platform 17 is provided in the installation groove a102, and an inclined downward inclined surface b is provided on the blocking platform 17, which can push the limiting platform 13 by the contact between the inclined surface b and the inclined surface a.

[0050] When installing the temperature and humidity field inspection meter 1, the baffle 17 pushes the limit platform 13 downward, the sliding rod a14 slides downward, and the elastic part a16 is compressed. When the temperature and humidity field inspection meter 1 moves to the innermost position, the elastic part a16 pushes the limit platform 13 to move upward, so that the limit platform 13 is blocked on the outside of the baffle 17, thereby realizing the installation of the temperature and humidity field inspection meter 1 and preventing the entire temperature and humidity field inspection meter 1 from falling.

[0051] like Figure 1 As shown, handles 40 are provided on both sides of the temperature and humidity field inspection meter 1, and storage grooves for the handles 40 to be moved into are provided on both sides of the installation shell 12. The handles 40 can facilitate users to place and remove the temperature and humidity field inspection meter 1.

[0052] Embodiment 3

[0053] like Figures 2 - 4 As shown, the present embodiment proposes a temperature and humidity field inspection device for environmental test equipment detection. Compared with the first embodiment, in the present embodiment, an extrusion platform 18 is provided at the lower part of the installation space, and the extrusion platform 18 has an inclined surface c inclined upward; a mounting groove b103 with an opening facing downward is provided at the back of the temperature and humidity field inspection instrument 1, and a pressure platform 19 is provided in the mounting groove b103 for sliding along the vertical direction, and the pressure platform 19 has an inclined surface d inclined downward for the extrusion platform 18 to push, and a rack 20 is vertically provided on the top of the pressure platform 19, and the rack 20 passes through the lower part of the temperature and humidity field inspection instrument 1 and is slidably connected with the temperature and humidity field inspection instrument 1. A wire blocking assembly is provided on the top of the temperature and humidity field inspection instrument 1 for sliding along the vertical direction, and the wire blocking assembly is located on one side of the cable winding mechanism; a transmission mechanism is connected between the rack 20 and the wire blocking assembly.

[0054] When the temperature and humidity field inspection instrument 1 is not installed in the installation space, the wire blocking assembly is located on one side of the cable winding mechanism, which can limit the wound signal transmission cable and prevent the signal transmission cable from falling off the ends of the inner rod 2 and / or the outer rod 5. When the temperature and humidity field inspection instrument 1 is installed in the installation space, the extrusion platform 18 pushes the pressure platform 19, the pressure platform 19 moves up and drives the rack 20 to move up, and the rack 20 drives the wire blocking assembly to move down through the transmission mechanism, thereby removing the shielding of the signal transmission cable wound on the cable winding mechanism, and conveniently and smoothly pulling out the signal transmission cable from the ends of the inner rod 2 and the outer rod 5.

[0055] like Figure 4 As shown, the wire blocking assembly includes a lifting column 27, a top plate 28, a sliding rod b29, an anti-slip platform 30, a connecting plate 31 and an elastic member b32. The lifting column 27 is slidably arranged on the temperature and humidity field inspection instrument 1 in the vertical direction, the top of the lifting column 27 is connected to the top plate 28, the sliding rod b29 is slidably arranged on the top plate 28 in the horizontal direction, and the two ends of the sliding rod b29 are respectively connected to the anti-slip platform 30 and the connecting plate 31. The anti-slip platform 30 faces the cable winding mechanism, and the two ends of the elastic member b32 are respectively connected to the top plate 28 and the anti-slip platform 30.

[0056] When adjusting the retraction or expansion of the inner rod 2 and the outer rod 5, the inner rod 2 and the outer rod 5 move in the horizontal direction. At this time, since the elastic member b32 has a certain stretching ability, it can automatically push the anti-detachment platform 30, so that the anti-detachment platform 30 can block on one side of the inner rod 2 and the outer rod 5 in different distribution states for limiting.

[0057] Such as Figure 2 and Figure 3 , the transmission mechanism includes gear a21, rotating shaft a22, gear b23, rotating shaft b24, rope winding roller 25, connecting rope 26, lifting plate 33, sliding column 34, elastic member c35 and fixing plate 36. The rack 20, gear a21 and gear b23 are sequentially meshed and connected. Gear a21 is arranged on rotating shaft a22. Gear b23 and rope winding roller 25 are coaxially arranged on rotating shaft b24. Rotating shaft a22 and rotating shaft b24 are both rotatably arranged on the temperature and humidity field inspection instrument 1. Connecting rope 26 is wound around rope winding roller 25. One end of connecting rope 26 away from rope winding roller 25 is connected to the bottom end of lifting column 27. Lifting plate 33 is arranged at the bottom of lifting column 27. Sliding column 34 is vertically arranged at the bottom of lifting plate 33. Sliding column 34 penetrates through fixing plate 36 and is slidably connected with fixing plate 36. Both ends of elastic member c35 are respectively connected to lifting plate 33 and fixing plate 36. Fixing plate 36 is arranged on temperature and humidity field inspection instrument 1 and is located below lifting plate 33.

[0058] When installing the temperature and humidity field inspection instrument 1 into the installation space, the extrusion platform 18 extrudes the bearing platform 19. The bearing platform 19 drives the rack 20 to move upward. The rack 20 drives gear a21 to rotate. Gear a21 drives gear b23 to rotate. Gear b23 drives rope winding roller 25 to rotate through rotating shaft b24. Rope winding roller 25 winds up connecting rope 26. Connecting rope 26 drives lifting column 27 to move downward, so that the anti-detachment platform 30 moves downward from one side of the cable winding mechanism. At the same time, lifting column 27 also drives lifting plate 33 to move downward. Lifting plate 33 compresses elastic member c35. Since the temperature and humidity field inspection instrument 1 is limited by the limiting platform 13 after installation, the extrusion platform 18 can maintain the extrusion state on the bearing platform 19, and the anti-detachment platform 30 maintains the lower position where it does not block and limit the cable winding mechanism. Only when the pull handle 15 is pulled downward and the temperature and humidity field inspection instrument 1 is removed outward, the elastic member c35 will push the lifting plate 33 to move upward, and use the lifting plate 33 to drive the lifting column 27 to move upward, so that the anti-detachment platform 30 re-blocks and limits on one side of the cable winding mechanism.

[0059] The elastic member a16, elastic member b32 and elastic member c35 are all compression springs. The elastic member a16 is sleeved on the sliding rod a14. The elastic member b32 is sleeved on the sliding rod b29. The elastic member c35 is sleeved on the sliding column 34. Multiple elastic members can stretch stably without falling off, have good position stability and long service life.

[0060] The usage method of the temperature and humidity field inspection device for the above-mentioned environmental test equipment detection includes the following steps:

[0061] S1. Install the installation shell 12 on the environmental test equipment to be detected through the side ear 121. The side ear 121 is provided with installation holes, and the installation is carried out through the installation holes. The installation shell 12 is pre-installed on all environmental test equipment to be detected. During subsequent inspections, the temperature and humidity field inspection instrument 1 can be very conveniently installed for detection, saving time. The temperature and humidity field inspection instrument 1 is in a stable installation state, facilitating personnel to carry out detection operations;

[0062] S2. Push the temperature and humidity field inspection instrument 1 into the installation space. During the movement of the temperature and humidity field inspection instrument 1, the blocking platform 17 pushes the limiting platform 13 downward through the inclined surface b and the inclined surface a, and the extrusion platform 18 pushes the bearing platform 19 upward through the inclined surface c and the inclined surface d;

[0063] S3. When the temperature and humidity field inspection instrument 1 abuts against the innermost side of the installation space, the limiting platform 13 is pushed upward by the elastic member a16 and is stuck between the blocking platform 17 and the innermost surface of the installation groove a102. The bearing platform 19 drives the rack 20 to move upward. The rack 20 drives the wire blocking assembly to move downward through the transmission mechanism. The anti-detachment platform 30 in the wire blocking assembly moves downward from one side of the wire winding mechanism, releasing the shielding of the wire winding mechanism, facilitating the subsequent pulling out of the wound signal transmission cable;

[0064] S4. Pull out the wound signal transmission cable from the wire winding mechanism, and connect the other end of the signal transmission cable to the sensor provided in the environmental test equipment to be detected;

[0065] S5. Start the temperature and humidity field inspection instrument 1 to perform temperature and humidity field calibration detection on the environmental test equipment to be detected.

[0066] Embodiment 4

[0067] As Figure 2 and Figure 3 shown, a temperature and humidity field inspection device for environmental test equipment detection proposed in this embodiment, compared with Embodiment 3, in this embodiment, a conductive joint a37 is insulatingly provided on the rack 20. An installation frame 39 is provided inside the temperature and humidity field inspection instrument 1. A conductive joint b38 that can be in electrical contact with the conductive joint a37 is insulatingly provided at the lower part of the installation frame 39. The conductive joint b38 is connected to a wire a381. One end of the wire a381 away from the conductive joint b38 is connected to a circuit board, and the circuit board is connected to the channel interface 101. A power supply is provided inside the temperature and humidity field inspection instrument 1, and a wire b (not shown) is connected between the power supply and the conductive joint a37.

[0068] In this embodiment, during the process of installing the temperature and humidity field inspection instrument 1 into the installation space, the rack 20 drives the conductive joint a 37 to move upward. Eventually, the conductive joint a 37 will contact the conductive joint b 38 to conduct electricity. The power of the power supply is transmitted to the circuit board through the wire b, the conductive joint a 37, the conductive joint b 38, and the wire a 381. The circuit board is used to supply power to the channel interface 101. The circuit board is the one used in the existing temperature and humidity field inspection instrument 1 that can perform temperature and humidity field calibration and detection on environmental test equipment. Through the above power-on process, the circuit board can only be powered after the temperature and humidity field inspection instrument 1 is installed for subsequent detection. When the temperature and humidity field inspection instrument 1 is not installed in place, the circuit board is in a power-off state, which is safer and more energy-efficient.
