Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] As described in the background section, current gas sensor design primarily focuses on the development and design of gas-sensitive materials, neglecting the integrated development of gas sensors. In experiments, clamps are often used to fix the interdigital electrodes, causing significant inconvenience in applications.

[0027] To solve this technical problem, this utility model provides a press-type elastic self-locking electrode slot module for a gas sensor.

[0028] For details, please refer to Figures 1-3 The press-type elastic self-locking electrode slot module of the gas sensor specifically includes a welding plate 1 and an elastic self-locking structure 2 disposed on the upper end of the welding plate 1.

[0029] The elastic self-locking structure 2 includes a base 3 fixedly connected to the top surface of the welding plate 1. The base 3 has an insertion groove 4 and a rectangular movable groove 9 inside. The rectangular movable groove 9 has a guide groove 10 on its surface that communicates with the insertion groove 4.

[0030] The gas sensor push-type elastic self-locking electrode slot module provided by this utility model has an elastic self-locking structure 2. The interdigital electrode 5 adopts a push-type self-locking structure, which can realize the quick installation and removal of the interdigital electrode 5 by pressing. By improving the connection method of the gas sensor, the work efficiency in the gas sensor replacement can be improved.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Please refer to Figures 1-6 A press-type elastic self-locking electrode slot module for a gas sensor, comprising a welding plate 1 and an elastic self-locking structure 2 disposed on the upper end of the welding plate 1.

[0033] The elastic self-locking structure 2 includes a base 3 fixedly connected to the top surface of the welding plate 1. The base 3 has an insertion groove 4 and a rectangular movable groove 9 inside. The rectangular movable groove 9 has a guide groove 10 on its surface that communicates with the insertion groove 4. The insertion groove 4 has an interdigitated electrode 5 inserted into its interior.

[0034] The surface of the interdigital electrode 5 is usually coated or chemically deposited with a gas-sensitive material. The electrical signal monitored by the interdigital electrode 5 is transmitted to the sensor part through metal leads, thereby enabling the monitoring of resistance changes during adsorption and the prediction of gas concentration and other information.

[0035] Specifically, a positioning seat 11 is fixedly connected to the inner wall of the guide groove 10, a shaft 12 is fixedly connected inside the positioning seat 11, a linkage push rod 13 is slidably connected to the surface of the shaft 12, the linkage push rod 13 is slidably connected to the inner wall of the positioning seat 11 and extends into the interior of the insertion groove 4, a locking tube 15 is fixedly connected to the inner wall of the guide groove 10, the locking tube 15 extends into the inner wall of the base 3, and a guide groove 16 is opened on the surface of the locking tube 15.

[0036] Specifically, a spring 14 is sleeved on the surface of the shaft 12, and the spring 14 is located between the positioning seat 11 and the linkage push rod 13. A rotating inner rod 20 is rotatably connected to the surface of the shaft 12, and a locking rod 21 is fixedly connected to the surface of the rotating inner rod 20. The end of the locking rod 21 is inclined. A certain gap is left between the rotating inner rod 20 and the middle of the linkage push rod 13 to ensure that the rotating inner rod 20 rotates. A top rod 18 is slidably connected to the middle of the locking tube 15. Connecting rods 17 are fixedly connected to both sides of the linkage push rod 13. The end of the connecting rod 17 away from the linkage push rod 13 is fixedly connected to the top rod 18. A guide slider 19 is fixedly connected to the surface of the top rod 18, and the guide slider 19 is slidably connected to the inner wall of the guide groove 16.

[0037] Specifically, the end of the rotating inner rod 20 away from the linkage push rod 13 is inserted into the inner wall of the top rod 18, and the locking rod 21 is slidably connected to the inner wall of the guide groove 16.

[0038] Specifically, the locking tube 15 and the top rod 18 are respectively provided with toothed grooves at the ends near the rotating inner rod 20. The toothed grooves at the end of the locking tube 15 and the toothed grooves at the end of the top rod 18 are staggered. The locking insert rod 21 is inserted into the inside of the toothed grooves of the locking tube 15 and the top rod 18.

[0039] Specifically, a terminal 6 is fixedly connected to the rear end of the base 3, and electrode plates 8 are symmetrically fixedly connected inside the base 3. The electrode plates 8 are electrically connected to the interdigital electrode 5 and the terminal 6 respectively, and a plug 7 is inserted into the inner wall of the terminal 6.

[0040] With the above structural design, during use, the interdigitated electrode 5 is pushed into the insertion slot 4. As the interdigitated electrode 5 moves into the insertion slot 4, its bottom end contacts the extension end of the linkage push rod 13, pushing the linkage push rod 13 to slide against the inner wall of the guide groove 10. Simultaneously, the linkage push rod 13 slides against the surface of the shaft 12 towards the positioning seat 11. The positioning seat 11, in conjunction with the linkage push rod 13, compresses and contracts the spring 14. As the linkage push rod 13 moves, it drives the top rod 18 to slide against the middle of the locking tube 15 towards the positioning seat 11 via the connecting rod 17. Simultaneously, the top rod 18 pushes the rotating inner rod 20 to slide against the surface of the shaft 12. The locking insert 21 on the surface of the rotating inner rod 20 slides out from inside the guide groove 16. Since the end of the locking insert 21 near the locking tube 15 is inclined and inserted into the front toothed groove of the top rod 18, after sliding out from inside the guide groove 16, the locking insert 21 passes through the top... The guide locking rod 21 of the toothed groove at the front end of the rod 18 rotates on the surface of the shaft 12. At this time, the locking rod 21 and the toothed groove at the front end of the locking tube 15 are in an interlaced state. At this time, the interdigital electrode 5 is engaged in the middle of the electrode plate 8. After the pressure on the interdigital electrode 5 is stopped, the spring 14 releases its elastic potential energy. The spring 14 pushes the linkage push rod 13 to slide on the surface of the shaft 12. The linkage push rod 13 pushes the top rod 18 to move into the interior of the locking tube 15 through the connecting rod 17. At the same time, the rotating inner rod 20 moves closer to the end of the locking tube 15 through the push of the linkage push rod 13. When the locking rod 21 contacts the toothed groove at the front end of the locking tube 15, it rotates. At the same time, the locking rod 21 is inserted into the middle of the toothed groove at the front end of the locking tube 15. After rotation, the locking rod 21 on the surface of the rotating inner rod 20 and the toothed groove at the front end of the top rod 18 are in an interlaced state. In this way, the interdigital electrode 5 can be quickly installed.

[0041] During disassembly, simply press the interdigital electrode 5. When the interdigital electrode 5 is under pressure, it works with the linkage push rod 13 to compress the spring 14. At the same time, the linkage push rod 13 drives the top rod 18 to move towards the positioning seat 11 via the connecting rod 17. As the top rod 18 moves, the toothed groove at its front end contacts the locking rod 21, which in turn pushes the locking rod 21 away from the middle of the toothed groove at the front end of the locking tube 15. Simultaneously, the locking rod 21 rotates and engages with the middle of the toothed groove at the front end of the top rod 18. After this is completed, stop applying pressure to the interdigital electrode 5. The spring 14 releases its elastic potential energy, pushing the linkage push rod 13 away from the positioning seat 11. At the same time, the locking rod 21 is guided by the toothed groove at the front end of the top rod 18 and inserted into the guide groove 16. When the locking rod 21 contacts the front end of the locking tube 15, it is guided by the toothed groove at the front end of the locking tube 15 and inserted into the guide groove 16, thereby achieving the disassembly of the interdigital electrode 5.
