Technical Field
[0001] This utility model relates to the field of signal connection technology, and in particular to a signal connection device for conductivity meter calibration. Background Technology
[0002] A conductivity meter is an online water quality analysis instrument used to detect the temperature of target water. It is commonly used in high-temperature environments such as boiler bottom water, heat exchange systems, industrial hot cleaning of mechanical parts, and industrial circulating water. The core component of a conductivity meter is its internal temperature sensor. According to relevant calibration specifications, the temperature sensor of the conductivity meter needs to be calibrated periodically. The common calibration method in existing technology is to use an AC resistance box capable of generating the target temperature, such as the NS04-ZX123B AC resistance box for conductivity meter calibration manufactured by Dongfang Chemical Breaker (Beijing) Technology Co., Ltd., whose indicated value directly represents the conductivity value.
[0003] A search revealed a signal connection device for conductivity meter calibration (authorization announcement number: CN 220585677U), which "comprising a resistance box side wire and at least two conductivity meter side wires. One end of the resistance box side wire is provided with a lug for connecting to an AC resistance box, and the other end of the resistance box side wire is provided with a first connector. The first connector is electrically connected to the lug via a cable within the resistance box side wire. One end of the conductivity meter side wire is provided with a first adapter connector for mating with the first connector, and the other end of the conductivity meter side wire is provided with at least two second connectors, each for mating with a corresponding model of conductivity meter. Each second connector is electrically connected to the first adapter connector via a cable within the conductivity meter side wire. This invention solves the technical problem in the prior art where a separate signal connection cable is required for each model of conductivity meter, resulting in a large number of laboratory signal connection cables and increased inventory costs."
[0004] Based on the aforementioned technologies, the applicant believes that when calibrating a conductivity meter, a cable is required for signal connection. The general connection method is to connect one end of the cable to the conductivity meter and the other end to other devices to achieve signal connection. However, since the cable used for signal connection is relatively long, it is usually rolled up and placed in a bag, which is inconvenient for storage. To address the above problems, we have introduced a signal connection device for conductivity meter calibration. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] The signal connection device for conductivity meter calibration disclosed in this utility model is mainly used in signal connection scenarios.
[0030] Reference Figure 1 - Figure 5A signal connection device for conductivity meter calibration includes a conductivity meter body 1, with connectors 2 fixedly connected at equal intervals to the top of the conductivity meter body 1. A storage groove 3 is provided inside the conductivity meter body 1, and a power groove 4 is provided on one side of the inside of the conductivity meter body 1. A connection mechanism is provided inside the conductivity meter body 1, including a winding assembly and a release assembly, which cooperate with each other. The winding assembly includes a fixing frame 51, which is fixedly connected to the bottom of the inner wall of the storage groove 3, and the top side of the fixing frame 51 is rotatably connected to... There is a take-up roller 52, and protective discs 53 are symmetrically fixedly connected to the outer side of the take-up roller 52. A rotating shaft 54 is fixedly connected inside the fixed frame 51. A first gear 55 is fixedly connected to the outer side of the rotating shaft 54. A second gear 56 is fixedly connected to the outer side of one of the two protective discs 53. The first gear 55 and the second gear 56 are meshed together. A ratchet 57 is fixedly connected to the outer side of the second gear 56. One end of the rotating shaft 54 extends to the outer side of the conductivity meter body 1 and is fixedly connected to a rotating plate 7. A rotating rod 8 is fixedly connected to the outer side of the rotating plate 7. The release assembly includes a rotating column 61, which is rotatably connected inside the power groove 4. A baffle plate 62 is fixedly connected to the outside of the rotating column 61. The bottom of the baffle plate 62 is inclined. The baffle plate 62 and the ratchet 57 cooperate with each other. A fixed seat 63 is fixedly connected to one side of the inner wall of the power groove 4. A slide rod 64 is slidably connected inside the fixed seat 63. A baffle plate 65 is fixedly connected to the outside of the slide rod 64. A spring 66 is sleeved on the outside of the slide rod 64. One end of the slide rod 64 extends to the outside of the fixed seat 63 and is fixedly connected to a translation frame 67. A sliding groove 69 is opened inside the baffle plate 62. A sliding column 68 is slidably connected inside the sliding groove 69. The sliding column 68 is fixedly connected to the translation frame 67. A pulling column 610 is slidably connected inside the conductivity meter body 1. The other end of the pulling column 610 and the slide rod 64 are fixedly connected.
[0031] In this embodiment: the rotating rod 8 rotates, driving the rotating plate 7 to rotate. The rotating plate 7 rotates, driving the first gear 55 to rotate, and the second gear 56 rotates, driving the winding roller 52 to rotate, thus starting to wind up the cable. Under the action of the ratchet 57 and the blocking plate 62, the wound cable will not fall off. When the cable needs to be retrieved, the operator holds the pulling column 610 with one hand and pulls it outward. The movement of the pulling column 610 causes the sliding rod 64 to slide inside the fixed seat 63, which in turn pulls the sliding column 68 to slide inside the sliding groove 69, thereby pulling the blocking plate 62 to rotate around the rotating column 61 until the bottom of the blocking plate 62 disengages from the outer surface of the ratchet 57. Through the design of the connecting mechanism, the convenient winding and unwinding function of the signal cable is realized. The winding assembly, through the cooperation of the fixed frame 51, winding roller 52, protective disc 53, rotating shaft 54, first gear 55, second gear 56 and ratchet 57, can stably wind up the signal line and prevent tangling or damage; the release assembly, through the cooperation of the rotating column 61, blocking plate 62, fixed seat 63, sliding rod 64, blocking disc 65, spring 66, translation frame 67, sliding column 68 and pulling column 610, can flexibly control the release of the signal line, avoid excessive loosening, facilitate storage, and has a simple structure and strong practicality.
[0032] In the above technical solution, considering the problem that the signal connection cable is relatively long and is usually rolled up and placed in a bag, making it inconvenient to store, the specific operation is as follows:
[0033] Reference Figure 1 - Figure 5 In a preferred embodiment, an L-shaped fixing rod 9 is fixedly connected to the outer side of the take-up roller 52, on the side away from the ratchet 57. An opening / closing door 10 is rotatably connected to the front of the conductivity meter body 1, and an observation window 12 is provided inside the opening / closing door 10.

[0035] Working principle: In actual use, the operator places one end of the cable on the outside of the L-shaped fixing rod 9, and then holds the rotating rod 8. The rotating rod 8 rotates, which drives the rotating plate 7 to rotate. The rotating plate 7 rotates, which drives the first gear 55 to rotate, and the second gear 56 rotates, which drives the take-up roller 52 to rotate, starting to wind up the cable. Under the action of the ratchet 57 and the blocking plate 62, the wound cable will not fall off. When the cable needs to be retrieved, the operator holds the pulling column 610 with one hand and pulls it outward. The movement of the pulling column 610 causes the sliding rod 64 to slide inside the fixing seat 63, which in turn pulls the sliding column 68 to slide inside the sliding groove 69, thereby pulling the blocking plate 62 to rotate around the rotating column 61 until the bottom of the blocking plate 62 disengages from the outer surface of the ratchet 57. At this time, the operator rotates the rotating rod 8 to drive the take-up roller 52 to rotate, which can loosen the cable.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
