[0030] To solve the problem of electrode film breakage caused by rotation during the installation of the electrode core, the present utility model proposes a snap spring fixed electrode structure, which avoids the risk of electrode film breakage caused by rotation during the installation of the electrode core through a snap connection method, and this structure can flexibly press the electrode core, which can better ensure the buffer pressure for pressing the electrode core. The present utility model can be applied to a lactic acid glucose electrode, and the lactic acid glucose electrode is designed into two major components: an electrode core and a motor housing assembly. The electrode core can be directly installed into the electrode housing assembly to form a lactic acid glucose electrode, which is used in conjunction with a blood gas electrolyte analyzer.

[0031] Specifically, please refer to Figures 1 to 9 , a preferred embodiment of the snap spring fixed electrode structure of the present utility model includes: an electrode housing 1, an electrode core 2, and a spring cover assembly 3. The electrode core 2 is disposed inside the electrode housing 1, the spring cover assembly 3 is disposed on the top of the electrode housing 1, one end of the spring cover assembly 3 is rotatably connected to one side of the electrode housing 1, and the other end of the spring cover assembly 3 is snap-connected to the other side of the electrode housing 1 through an elastic snap component 16.

[0032] Among them, the elastic snap component 16 includes a compression spring 4 and a button 5. One end of the compression spring 4 is connected to the other end of the spring cover assembly 3, the other end of the compression spring 4 is connected to the top of the button 5, the middle of the button 5 is rotatably connected to the spring cover assembly 3 through a first pin shaft 6, a snap 7 is provided at the bottom of the button 5, and an inverted buckle structure 8 corresponding to the snap 7 is provided at the top of the electrode housing 1.

[0033] The spring cover assembly 3 includes a spring 9, a spring cover 10, a contact 11, and a ball plunger 12. The ball plunger 12 is disposed inside the spring cover 10, the spring 9 is threadedly connected to the spring cover 10 through the contact 11, and the bottom of the ball plunger 12 abuts against the spring 9.

[0034] In this embodiment, the spring 9 is a gold-plated spring 9, and the contact 11 is a gold-plated contact 11.

[0035] In this embodiment, one end of the spring cover 10 is rotatably connected to one side of the electrode shell 1 through the second pin shaft 13 .

[0036] In this embodiment, a flow path hole 14 is provided on the electrode shell 1. The flow path hole 14 also serves as a small part of the blood gas electrolyte analyzer.

[0037] In this embodiment, an O-shaped sealing ring 15 is disposed at the bottom of the electrode core 2 in the electrode shell 1 .

[0038] The assembly process of the utility model's snap spring fixed electrode structure is as follows:

[0039] First, install the ball plunger 12 into the shrapnel cover 10, and fix the gold-plated shrapnel 9 to the shrapnel cover 10 by threading through the gold-plated contact 11. The elastic buckle assembly 16 includes a first pin shaft 6, a button 5 and a shrapnel 9. A buckle 7 is provided at the bottom of the button 5. The electrode shell 1 has an inverted structure 8 matching the buckle 7 at the corresponding position. After the overall shrapnel cover assembly 3 is installed, the second pin shaft 13 is inserted to form a flip cover structure that can press the electrode core 2. During the process of loading the electrode core 2, first open the flip cover structure, install the O-ring 15, and then install the electrode core 2. The role of the O-ring is to prevent the flow path of the electrode shell 1 from leaking gas or liquid. When the flip cover structure presses the electrode, the elastic buckle assembly 16 and the electrode shell 1 are locked together. At this time, the gold-plated spring 9 just presses on the silver tube of the electrode core 2 to form conduction. The ball head plug can also adjust the bumping ball slightly according to the height of the electrode core 2 to achieve a buffering effect, which can effectively prevent the electrode core 2 from being too long or too short. The gold-plated spring 9 can still stick tightly to the silver tube. Thereby ensuring the performance reliability of the electrode core 2 after it is loaded into the electrode shell 1. If you want to take out the electrode core 2, just press the button 5 to open and take out the electrode core 2. It is very convenient to disassemble and assemble.
