Description

Technical Field

[0001] This utility model relates to the field of AC resistance box technology, and in particular to an AC resistance box specifically for calibrating conductivity meters. Background Technology

[0002] A conductivity meter is an instrument used to measure the conductivity of a solution, and it is widely used in environmental monitoring, water quality analysis, and industrial production. The dedicated AC resistance box for conductivity meter calibration is a standard solution conductivity simulation device specifically designed for calibrating various conductivity meters and similar instruments applicable to JJG376-2007 "Verification Procedure for Conductivity Meters". The indicated value is directly expressed as the conductivity value. During operation, the conductivity value is switched by changing the switch position. During the calibration process, operators do not need to perform conversions between resistance and conductivity values, making it intuitive and convenient to use.

[0003] A search revealed a special AC resistance box for calibrating conductivity meters (authorization announcement number: CN 213658810U). The invention discloses an AC resistance box for calibrating conductivity meters, comprising an AC resistance box body and a U-shaped frame. The AC resistance box body is placed inside the U-shaped frame, and side columns are fixedly connected to both sides of the AC resistance box body. Slotted openings are provided on the inner walls of both sides of the U-shaped frame, and these openings allow for slidable connection between the inner walls of the U-shaped frame and the side columns on both sides of the AC resistance box body. A rotating shaft is fixedly connected to the bottom of the U-shaped frame, and a base is connected to the bottom of the rotating shaft. Side plates are fixedly connected to the outer walls of both sides of the U-shaped frame, with fasteners threaded onto the top of the side plates and connecting plates slidably fitted onto the front of the side plates. This invention solves the problem of tangled wiring in AC resistance boxes, facilitating their arrangement and leading to better application prospects.

[0004] Based on the aforementioned technologies, the applicant believes that the technology only involves wrapping the wire around the outside of the drum, lacking a limiting mechanism for the wire. In actual use, the wire may not be able to maintain a tight fit with the outer wall of the drum due to its own toughness, which is a certain shortcoming in actual use. In order to address the above problems, we have launched a special AC resistance box for calibrating conductivity meters. Utility Model Content

[0005] This utility model discloses a special AC resistance box for calibrating conductivity meters, aiming to solve the technical problem that the above-mentioned technology simply wraps the wire around the outside of the drum without a limiting mechanism for the wire. In actual use, the wire may not be able to keep in close contact with the outer wall of the drum due to its own toughness, which is a certain shortcoming in actual use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dedicated AC resistance box for calibrating conductivity meters includes a resistance box body. The back of the resistance box body has equidistant wiring grooves, and the outer side of the resistance box body has a wiring mechanism. The wiring mechanism includes a support component and a pressing component, which cooperate with each other. The support component includes a rotating shaft, which is symmetrically rotatably connected to the outer side of the resistance box body. Rotating ends are fixedly connected to the outer sides of both rotating shafts. Rotating rods are symmetrically rotatably connected to the outer side of the resistance box body and below the rotating shafts. Rotating blocks are fixedly connected to the tops of both rotating rods, and mounting bases are rotatably connected to the tops of both rotating blocks. Each base has a sliding sleeve fixedly connected to its top. The sliding sleeve is hollow inside, and a sliding column is slidably connected inside the sliding sleeve. A fixed rod is fixedly connected to the bottom of the rotating end. The fixed rod extends into the sliding sleeve and is fixedly connected to the top of the sliding column.

The tension spring always maintains an upward contraction tension. A support column is rotatably connected between the two rotating rods. Wire grooves are equidistantly opened on the outside of the support column.

[0008] By setting up a ground wiring mechanism, the wires can be arranged in an orderly manner in the wire groove of the support column and kept stable by the tension of the tension spring, preventing them from loosening or falling off. It also avoids the situation where the wires do not fit properly due to their own toughness. The structure is simple and highly practical.

[0010] The set-in pressing component can limit the wire and assist in pressing and fixing it.

[0011] In a preferred embodiment, omnidirectional wheels are symmetrically provided on both sides of the bottom of the resistor box body, and the omnidirectional wheels have a locking function.

[0012] The casters at the bottom of the resistor box facilitate the movement and securing of the equipment.

[0013] In a preferred embodiment, a pull rod is fixedly connected to the bottom of the two rotating rods.

[0014] The pull rod allows staff to easily rotate the rotating rod.

[0015] In a preferred embodiment, a display screen is fixedly connected to the front of the resistor box body, and a control area is provided on the front of the resistor box body and above the display screen.

[0016] The front display screen and control area allow users to monitor and operate the equipment in real time.

[0017] In a preferred embodiment, both the support column and the rotating roller are provided with silicone pads on their outer sides for protecting the wires.

[0018] The silicone pads on the outside of the support columns and rotating rollers effectively protect the wires and prevent them from being worn during movement.

[0019] The AC resistance box for calibrating conductivity meters provided by this utility model has the following advantages:

[0020] Firstly, by setting up a ground wiring mechanism, it can ensure that the wires are arranged in an orderly manner in the wire groove of the support column, and maintain stability through the tension of the tension spring to prevent them from loosening or falling off. It also avoids the situation where the wires do not fit properly due to their own toughness. The structure is simple and highly practical.

[0021] Secondly, the casters at the bottom of the resistor box facilitate the movement and securing of the equipment, while the display screen and control area on the front allow users to monitor and operate the equipment in real time.

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.

[0030] The AC resistance box disclosed in this utility model is a special AC resistance box for verifying conductivity meters and is mainly used in AC resistance box application scenarios.

[0031] Reference Figure 1 - Figure 6A special AC resistance box for calibrating conductivity meters includes a resistance box body 1. Wiring grooves 4 are equidistantly arranged on the back of the resistance box body 1. A wiring mechanism is provided on the outer side of the resistance box body 1. The wiring mechanism includes a support component and a pressing component, which cooperate with each other. The support component includes a rotating shaft 51, which is symmetrically rotatably connected to the outer side of the resistance box body 1. Rotating ends 52 are fixedly connected to the outer sides of both rotating shafts 51. Rotating rods 58 are symmetrically rotatably connected to the outer side of the resistance box body 1 and below the rotating shafts 51. Rotating blocks 59 are fixedly connected to the tops of both rotating rods 58. Mounting seats 54 are rotatably connected to the tops of both rotating blocks 59. A mounting base 54 is fixedly connected to the top of both mounting seats 54. The sliding sleeve 55 is hollow inside. A sliding column 56 is slidably connected inside the sliding sleeve 55. A fixing rod 57 is fixedly connected to the bottom of the rotating end 52. The fixing rod 57 extends into the interior of the sliding sleeve 55 and is fixedly connected to the top of the sliding column 56. The fixing rod 57 and the sliding sleeve 55 are slidably connected. A tension spring 53 is sleeved on the outside of the fixing rod 57 and the sliding sleeve 55. The top of the tension spring 53 is fixedly connected to the bottom of the rotating end 52, and the bottom of the tension spring 53 is fixedly connected to the top of the mounting base 54. The tension spring 53 always maintains an upward contraction tension. A support column 510 is rotatably connected between the two rotating rods 58. Wire grooves 511 are equidistantly opened on the outside of the support column 510. The pressing assembly includes a fixing frame 61, which is fixedly connected to the back of the resistor box body 1. Fixing posts 62 are fixedly connected at equal intervals at the bottom of the fixing frame 61. Fixing blocks 63 are fixedly connected to the bottom of the fixing posts 62. Rotating rollers 64 are rotatably connected inside the fixing blocks 63. Wire grooves 65 are symmetrically opened on the outer side of the rotating rollers 64.

[0032] In this embodiment: the AC resistance box for verifying conductivity meters achieves orderly arrangement and fixation of wires through the design of the wiring groove 4 and the wiring mechanism. In actual use, the operator pulls the lever 8 by hand, which pulls down the two rotating rods 58. The two rotating rods 58 rotate around the resistor box body 1, thereby causing the support column 510 to move downward and no longer be in contact with the rotating roller 64. Then, the operator passes the wire between the rotating roller 64 and the support column 510, placing the wire inside the wire groove 511 and the wire passage groove 65. Then, the operator releases the lever 8, and the tension spring 53 pulls the support column 510 upward. The sliding column 56 slides upward inside the sliding sleeve 55, thereby pulling the support column 510 to be in contact with the bottom of the rotating roller 64. By setting up a grounding wire routing mechanism, it can be ensured that the wire is arranged in an orderly manner in the wire groove 511 of the support column 510 and kept stable by the tension of the tension spring 53, preventing it from loosening or falling off. It also avoids the situation where the wire does not fit due to its own toughness. The structure is simple and highly practical.

[0033] The above technical solution, considering that it only involves wrapping the wire around the outside of the drum and lacks a limiting mechanism for the wire, may not always be able to fit tightly against the outer wall of the drum due to its own toughness during actual use. Therefore, there are certain shortcomings in practical application. To solve this problem, the specific operation is as follows:

[0034] Reference Figure 1 - Figure 6 In a preferred embodiment, casters 7 are symmetrically arranged on both sides of the bottom of the resistor box body 1, and the casters 7 have a locking function. Pull rods 8 are fixedly connected to the bottom of the two rotating rods 58. A display screen 2 is fixedly connected to the front of the resistor box body 1, and a control area 3 is provided on the front of the resistor box body 1 and above the display screen 2. Silicone pads for protecting wires are provided on the outer sides of the support column 510 and the rotating rollers 64.

[0035] In this embodiment: the casters 7 at the bottom of the resistor box body 1 facilitate the movement and fixation of the equipment, while the display screen 2 and control area 3 on the front allow users to monitor and operate the equipment in real time. The silicone pads on the outside of the support column 510 and the rotating rollers 64 effectively protect the wires and prevent them from being worn during movement.

[0036] Working Principle: This AC resistance box for verifying conductivity meters achieves orderly arrangement and fixation of wires through the design of the wiring groove 4 and the wiring mechanism. In actual use, the operator pulls the pull rod 8 by hand, which pulls down the two rotating rods 58. The two rotating rods 58 rotate around the resistance box body 1, thereby driving the support column 510 to move downward and no longer contact with the rotating roller 64. Then, the operator passes the wire between the rotating roller 64 and the support column 510, placing the wire inside the wire groove 511 and the wire passage groove 65. Then, the operator releases the hand that pulled the pull rod 8, and the tension spring 53 pulls the support column 510 upward. The sliding column 56 slides upward inside the sliding sleeve 55, thereby pulling the support column 510 to contact the bottom of the rotating roller 64, ensuring that the wire is orderly arranged in the wire groove 511 of the support column 510 and is kept stable by the tension of the tension spring 53, preventing it from loosening or falling off. The casters 7 at the bottom of the resistor box body 1 facilitate the movement and fixation of the equipment, while the display screen 2 and control area 3 on the front allow users to monitor and operate the equipment in real time. The silicone pads on the outside of the support column 510 and the rotating rollers 64 effectively protect the wires and prevent them from being worn during movement.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. 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.
