Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas measurement and calibration technology, and in particular to a calibration device for an electrochemical oxygen analyzer. Background Technology
[0002] The electrochemical oxygen analyzer utilizes the redox reaction between the electrode and oxygen. When oxygen diffuses into the electrode, it reacts with the catalyst on the working electrode, reducing oxygen to hydroxide ions and generating electrons. This leads to charge transfer and the formation of an electric current. The magnitude of the current is proportional to the oxygen concentration. The oxygen concentration is calculated by measuring the current. During the use of the electrochemical oxygen analyzer, a calibration device ensures the accuracy and reliability of the gas analyzer's measurement results.
[0003] According to research, existing electrochemical oxygen analyzer calibration devices generally have two tanks and no external protective structure. During the testing and calibration process, the device is easily damaged if it is accidentally dropped. Utility Model Content
[0004] The purpose of this invention is to provide a calibration device for an electrochemical oxygen analyzer to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a calibration device for an electrochemical oxygen analyzer, comprising: a mounting base plate and a mounting bracket;
[0006] The mounting bracket is fixedly connected to the top of the mounting base plate. Fastening frames are fixedly connected to both sides of the mounting bracket. Air tanks and test gas tanks are symmetrically arranged in the fastening frames on both sides. A connector is provided at the top of the mounting bracket. A handle is provided on one side of the connector. Protective blocks are provided on both sides of the top of the mounting bracket.
[0007] Preferably, the fastening frame includes a fixed frame that is fixedly connected to both sides of the mounting bracket, and a movable frame is movably connected to one side of the fixed frame via a pivot. The movable frame and the fixed frame are provided with a fixing component at one end.
[0008] Preferably, the fixing component includes a locking block fixedly disposed at one end of the movable frame, a locking groove is provided at one end of the fixing frame, a limit block is movably connected to the outside of the locking groove, a guide rod is provided on the outside of the locking groove, and a reset spring is sleeved on the outer surface of the guide rod.
[0009] Preferably, the size of the locking groove is adapted to the size of the locking block, and the limiting block is movably connected to the guide rod through a reset spring.
[0010] Preferably, two sets of movable frames and fixed frames are provided correspondingly, and protective pads are adhered to both the movable frame and the fixed frame and the inner wall of the outer surface.
[0011] Preferably, the mounting base plate is provided with grooves that are adapted to the bottom of the air tank and the test gas tank.
[0012] Preferably, the number of protective blocks is set in two sets, the protective blocks are arranged symmetrically, a spring damping rod is connected inside the protective block, the protective block is movably connected to the mounting bracket through the spring damping rod, and a protective pad is also provided on the outer surface of the protective block.
[0013] Preferably, a flow meter is provided on the outside of the mounting bracket, and the connector is connected to the flow meter through a connecting pipe.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention allows air tanks and test gas tanks to be placed inside a fastening frame, with their bottoms engaging with corresponding grooves on the mounting base. By rotating the movable frame to close, the locking block compresses and retracts the limiting block, causing the locking block to engage in the locking groove. A return spring then moves the limiting block back to its original position on the guide rod, locking the locking block into the locking groove. The fastening frame closes quickly, achieving rapid fixation of the air tank and test gas tank. The air tank and test gas tank can then be connected to a flow meter via a connector, completing the assembly process.
[0016] This invention provides initial protection against the impact of a fall by using protective pads on the outer surface of the protective block. After initial protection, the impact force causes the protective block to further compress the spring damping rod, converting the impact force into elastic potential energy. This energy is then dissipated through the contraction of the damping rod, reducing damage to the device upon fall. Additionally, protective pads are adhered to both the movable frame and the fixed frame, as well as the inner wall of the outer surface. The inner protective pads protect the fastening frame and the tank, while the outer protective pads protect the device from external impacts, further reducing damage to the tank upon fall.

[0039] Specifically, there are two sets of protective blocks 8, which are arranged symmetrically. Each protective block 8 has a spring damping rod 801 connected inside it. The protective block 8 is movably connected to the mounting bracket 2 through the spring damping rod 801. The outer surface of the protective block 8 is also provided with a protective pad.
[0040] Specifically, a flow meter 201 is provided on the outside of the mounting bracket 2, and the connector 6 is connected to the flow meter 201 through a connecting pipe.
[0041] In this embodiment, to facilitate quick assembly of the device, the fastening frame 3 includes a fixed frame 301 fixedly connected to both sides of the mounting bracket 2. A movable frame 302 is movably connected to one side of the fixed frame 301 via a rotating shaft. A fixing component 303 is provided at one end of the movable frame 302 and the fixed frame 301. The fixing component 303 includes a locking block 304 fixedly disposed at one end of the movable frame 302. A locking groove 305 is provided at one end of the fixed frame 301.

Each protective block 8 has a spring damping rod 801 connected inside, and is movably connected to the mounting bracket 2 via the spring damping rod 801. A protective pad is also provided on the outer surface of each protective block 8 to provide initial protection against the impact of a fall. After initial protection, the impact force causes the protective block 8 to further compress the spring damping rod 801, converting the impact force into elastic potential energy, which is then dissipated through the contraction of the damping rod, thus mitigating damage to the device upon fall.

[0045] Based on the above embodiments, during assembly, air tank 4 and test gas tank 5 can be placed inside fastening frame 3, with their bottoms engaging with the corresponding grooves on mounting base plate 1. Then, by rotating movable frame 302 to close, locking block 304 compresses limiting block 306, causing locking block 304 to engage with locking groove 305. Return spring 307 then drives limiting block 306 to reset on guide rod 308, locking locking block 304 into locking groove 305. The quick fastening frame 3 closes, achieving quick fixation of air tank 4 and test gas tank 5. Finally, connecting head 6 connects air tank 4 and test gas tank 5 to flow meter 201. Once connected, the assembly is complete. When the device falls, the protective pads on the outer surface of the protective block 8 provide initial protection against the impact. After initial protection, the impact force causes the protective block 8 to further compress the spring damping rod 801, converting the impact force into elastic potential energy. This energy is then dissipated through the contraction of the damping rod, reducing the damage to the device when it falls. Meanwhile, protective pads are adhered to both the movable frame 302 and the fixed frame 301, as well as the inner wall of the outer surface. The inner protective pads protect the fastening frame 3 and the tank, while the outer protective pads protect the outside of the device when it falls, further reducing the damage to the tank when it falls.
