[0002] A thermometer is an instrument that uses different principles to measure the temperature or temperature gradient of an object (or space). Common types include bimetallic thermometers with pointers and dials, which can directly measure gases, liquids, and steam. They are widely used in machinery, shipbuilding, petrochemicals, metallurgy, power, light industry, and research.

[0003] Most pointer bimetallic thermometers are installed using a threaded connection, where the movable nut on the outside of the protective tube is threaded onto the fixing nut on the device being measured, making installation and disassembly convenient. However, in actual industrial environments, other devices may be present around the installation location of the pointer bimetallic thermometer. These devices can obstruct the rotation area of ​​the movable nut, resulting in limited space for rotation and making disassembly inconvenient. Therefore, this paper proposes an industrial thermometer that is easier to install. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 In this embodiment of the present invention, an industrial thermometer that is easy to fix and install includes a thermometer 1 consisting of a dial 101 and a protective tube 102. The protective tube 102 is fixed to the bottom of the dial 101, and a quick-installation component 2 is provided on the outside of the protective tube 102. The quick-installation component 2 is used to realize the quick installation of the thermometer 1 and the device being measured.

[0021] The quick-installation assembly 2 includes a docking unit, a quick-locking unit, and a protective unit. The docking unit is used to connect and install the dial 101 with the device under test. The quick-locking unit is used to lock and fix the docking unit. The protective unit is used to protect the quick-locking unit from dust and to limit the movement of the quick-locking unit.

[0022] The docking unit includes a sealing plug 201, a docking sleeve 202, a base block 204, and a connecting sleeve 205. The sealing plug 201 and the docking sleeve 202 are fixed to the outside of the protective tube 102, and the sealing plug 201 is distributed inside the docking sleeve 202. The connecting sleeve 205 is fixed to the top of the base block 204. The base block 204 is fixed to the temperature measuring port of the device under test by welding. A through hole is formed in the middle of the base block 204 for the protective tube 102 to pass through. The protective tube 102 is inserted into the inside of the device under test through the through hole. The sealing plug 201 is inserted into the inside of the connecting sleeve 205, and the docking sleeve 202 is sleeved on the outside of the connecting sleeve 205 to achieve the installation and sealing of the protective tube 102.

[0023] The quick-lock unit includes an annular toothed groove 203, a rotating support block 206, a linkage gear 207, and an L-shaped arm 208. Multiple sets of rotating support blocks 206 are arranged in pairs, and these sets are evenly distributed in a ring around the connecting sleeve 205. The linkage gear 207 is rotatably mounted between two rotating support blocks 206. The vertical part of the L-shaped arm 208 is fixed to the outside of the linkage gear 207. Multiple annular toothed grooves 203 are formed on the outside of the mating sleeve 202 and are arranged vertically. When the mating sleeve 202 is fitted onto the outside of the connecting sleeve 205, the annular toothed groove 203 and the linkage gear 207 engage. The L-shaped arm 208 is manually moved upwards to achieve quick engagement of the sealing plug 201, the annular toothed groove 203, and the connecting sleeve 205.

[0024] The protective unit includes a protective cover 210 and a spring 211. The protective cover 210 is slidably sleeved on the outside of the protective tube 102 and distributed above the docking sleeve 202. The spring 211 is distributed between the top of the protective cover 210 and the bottom of the dial 101 and sleeved on the outside of the protective tube 102. The protective cover 210 moves down to form a sleeve with multiple linkage gears 207 and L-shaped arms 208, which is used to achieve dust protection for the annular tooth groove 203 and the linkage gears 207, and at the same time limit the flipping of the L-shaped arms 208 to achieve the installation and locking of the temperature gauge 1.

[0025] In this embodiment, the installation steps for this temperature gauge 1 are as follows:

[0026] First, fix the base block 204, connecting sleeve 205, rotating support block 206, linkage gear 207, and L-shaped arm 208 onto the device under test. Then, fix the base block 204 to the device under test by welding, and align the through hole on the base block 204 with the temperature measuring port on the device under test.

[0027] Then, the protective tube 102 is aligned with the through hole on the bottom block 204 and inserted so that the protective tube 102 is inserted into the device under test. During this process, the sealing plug 201 is inserted into the connecting sleeve 205 and the docking sleeve 202 is sleeved on the outside of the connecting sleeve 205. At this time, the annular tooth groove 203 meshes with the linkage gear 207. Then, as the docking sleeve 202 continues to move down, the linkage gear 207 is driven to rotate, and the L-shaped arm 208 is driven to rotate upward (it should be noted that the initial state of the L-shaped arm 208 is with the vertical part facing down, and when installing the thermometer 1, the protective cover 210 is manually lifted upward so that the protective cover 210 is away from the rotation area of ​​the L-shaped arm 208).

[0028] The more the sealing plug 201 contacts the connecting sleeve 205, the greater the friction. Therefore, it is not convenient to fully insert the sealing plug 201 into the connecting sleeve 205 later. At this time, the L-shaped arm 208 can be manually moved. By using the lever principle, the thermometer 1, sealing plug 201 and connecting sleeve 205 can be pushed downward as a whole. Finally, the sealing plug 201 is fully inserted into the connecting sleeve 205. At this time, the vertical part of the L-shaped arm 208 is vertically upward.

[0029] Afterwards, the lifting operation of the protective cover 210 is released. Under the elastic force of the spring 211, the protective cover 210 moves down. Finally, the protective cover 210 is sleeved on the outside of the multiple linkage gears 207, the L-shaped arm 208 and the base block 204, realizing dust protection for the annular tooth groove 203 and the linkage gears 207, while limiting the rotation of the L-shaped arm 208, thus realizing the fixed locking of the temperature gauge 1.

[0030] Compared to traditional threaded connection structures, the above operation process eliminates the need for multiple turns of tightening, making it better suited for installation in confined spaces and effectively improving the ease of installation and applicability of the thermometer 1.

[0031] Please refer to this carefully. Figures 2-5 One end of the lateral part of the L-shaped arm 208 is fixed with an arc-shaped clamp 209, and the inner diameter of the annular structure composed of multiple arc-shaped clamps 209 matches the outer diameter of the protective tube 102.

[0032] An inner limiting ring 212 is fixed to the top of the inner side of the protective cover 210. The inner diameter of the inner limiting ring 212 matches the outer diameter of the vertical parts of the multiple L-shaped arms 208.

[0033] In this embodiment: the inner limiting ring block 212 is sleeved with the outer side of the vertical part of multiple L-shaped arms 208, and the arc-shaped clamp block 209 is attached to the outer side of the protective tube 102, so that the L-shaped arms 208 cannot rotate at this time, thus ensuring the installation stability of the temperature gauge 1.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
