[0002] Oxygen sensors are devices that measure the oxygen concentration in air or gas mixtures and are widely used in various fields. The oxygen sensor connection base is a key component for installing and securing the oxygen sensor. The connection base ensures that the oxygen sensor can stably and accurately detect the oxygen concentration in the gas.

[0003] At present, there are some connection base structures on the market, such as an oxygen sensor mounting base and oxygen sensor disclosed on the China Patent Network, with the publication number CN218177309U. These connection base structures can be used for the installation and fixation of oxygen sensors, but there are some defects and deficiencies that need to be improved: (1) Some existing connection bases install and fix the oxygen sensor by threaded connection, but the size of the threaded interface is mostly fixed, and it is difficult to adjust or replace the threaded interface of the connection base according to the size of the oxygen sensor, which may cause compatibility problems between oxygen sensors of different models and brands and the connection base, thereby reducing the applicability of the connection base, and when the threaded interface is worn due to long-term installation and removal, it is difficult to replace it separately; (2) In order to prevent the oxygen sensor from offsetting and loosening during use, some existing connection bases will set corresponding limiting structures on the connection base, but these limiting structures are often fixed on the connection base, which is difficult to adjust according to the size of the oxygen sensor and difficult to disassemble at will, making it inconvenient to maintain and replace the limiting mechanism. Therefore, in response to the above problems, the oxygen sensor connection base provided by the utility model is of great significance. Utility Model Content

When the connecting assembly is fixed below the mounting bracket 1, the threaded interface 11 can pass through the connecting port 4 and extend to the top of the mounting bracket 1. At this time, the bottom of the oxygen sensor can be threadedly connected to the threaded interface 11, so that the oxygen sensor can be installed and fixed by means of a threaded connection.

[0031] The limit assembly includes a limit cover 12, which is a rectangular parallelepiped with a hollow structure inside. A limit opening 13 is provided on the top of the limit cover 12.

A plurality of heat dissipation holes 17 are provided on the side wall surface of the limit cover 12. When the oxygen sensor works for a long time, the heat in the limit cover 12 can be discharged in time through each heat dissipation hole 17 to achieve the effect of heat dissipation. The inner wall of the limit cover 12 is fixedly connected to a fixing rod 18, and the end of the fixing rod 18 is fixedly connected to a limit plate 19.

At this time, the oxygen sensor can be clamped by the limit openings 13 and the limit plates 19 on the two limit covers 12 to achieve the effect of limiting, thereby avoiding the oxygen sensor from deflecting and loosening during use.

The connecting assembly can be designed as a plurality of standard parts with threaded interfaces 11 of different diameters. The connecting assembly with the corresponding threaded interface 11 size can be selected according to the size of the oxygen sensor, thereby effectively solving the compatibility issues that may exist between oxygen sensors of different models and brands and the connecting base, and improving the applicability of the connecting base.

The adjustment hole 8 is a rectangular hole structure, and the width of the adjustment hole 8 is equal to the diameter of the thread groove 15. The limit cover 12 can drive the protrusion 14 to move horizontally along the adjustment seat 7, and the adjusting bolt 16 can pass through the adjusting hole 8 and be screwed into the thread groove 15, so that the position of the limit assembly can be adjusted and fixed according to the size of the oxygen sensor, so that the limit assembly can always fit tightly with the oxygen sensor, and the entire limit assembly can be removed by unscrewing the adjusting bolt 16 to facilitate maintenance and replacement of the limit assembly.

[0034] Among them, the limiting opening 13 is semicircular, and its center is located on the same straight line as the center of the connecting port 4, and a layer of sealing gasket 20 is provided on the inner wall of the limiting opening 13 and the side wall surface of the limiting cover 12. The sealing gasket 20 can be made of elastic materials such as rubber and is fixed by glue. When the two limiting components are respectively attached to the two sides of the oxygen sensor, the sealing gasket 20 can effectively fill the gap between the two limiting covers 12 to play a sealing role.

[0035] Among them, the limiting plate 19 is arc-shaped, and its diameter is equal to the diameter of the limiting opening 13, and the center of the limiting plate 19 and the center of the limiting opening 13 are located on the same straight line. A layer of buffer pad 21 is provided on the inner wall surface of the limiting plate 19. The buffer pad 21 can be made of elastic materials such as sponge and is fixed by glue. When the limiting plate 19 clamps the oxygen sensor, the buffer pad 21 can play a buffering protection effect to avoid direct contact between the oxygen sensor and the inner wall of the limiting plate 19 to cause collision and wear.

[0036] Among them, a pair of blocks 22 are fixedly connected to the side walls of the limit cover 12, the side surfaces of the blocks 22 are L-shaped, and are respectively located above and below each heat dissipation hole 17, and a dustproof net 23 is arranged between the blocks 22.
