Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, specifically a temperature sensor with a sealed structure. Background Technology

[0002] A temperature sensor is a device that converts temperature signals into measurable electrical signals or other forms of signals. It plays a crucial role in industries, agriculture, scientific research, home appliances, and medical fields. When using a temperature sensor, the detection probe and the temperature sensor housing are usually connected by welding or threaded connection. When using threaded connection, poor sealing is prone to occur, which can easily damage the internal components of the housing. On the other hand, welding connection makes it difficult to replace the probe when it is damaged, affecting the convenience of use. Therefore, a temperature sensor with a sealed structure is needed.

[0003] However, due to the poor installation and disassembly capabilities of temperature sensors with sealed structures in existing technologies, it is not convenient to install and connect the detection probe to the temperature sensor housing according to the usage needs during actual use. Usually, welding or multiple bolts or threaded connections are used for fixing, which is not convenient for connection and disassembly, affecting the ease of use. Utility Model Content

[0020] 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.

[0021] Please see Figures 1-4This utility model provides a technical solution: a temperature sensor with a sealed structure, including a temperature sensor body 1, an mounting sleeve 2 fixedly installed at the top of the temperature sensor body 1, a mounting connecting sleeve 3 movably connected to the top of the mounting sleeve 2, a probe 4 fixedly installed at the top of the mounting connecting sleeve 3, the probe 4 being electrically connected to the temperature sensor body 1, a plurality of positioning holes 5 evenly distributed at the top of the mounting sleeve 2, a plurality of positioning rods 6 evenly fixedly installed at the bottom of the mounting connecting sleeve 3, the positioning rods 6 being movably connected to the positioning holes 5, support tubes 7 fixedly installed on both sides of the mounting sleeve 2, a movable rod 8 movably installed inside the support tube 7, the movable rod 8 extending into the interior of the mounting sleeve 2, a limit block 9 fixedly installed on the side of the movable rod 8 away from the mounting sleeve 2, and a positioning block 10 fixedly installed on the side of the movable rod 8 away from the limit block 9. A connecting spring 11 is fixedly installed inside component 7. The connecting spring 11 is sleeved on the outer end of the movable rod 8. A connecting groove 12 is opened at the top of the mounting sleeve 2. A connecting ring 13 is fixedly installed at the bottom of the mounting sleeve 3. Positioning connecting holes 14 are opened on both sides of the connecting ring 13. The positioning plug 10 is movably connected to the positioning connecting hole 14. The positioning plug 6 at the bottom of the mounting sleeve 3 is aligned with the positioning plug 5 at the top of the mounting sleeve 2 and inserted. The connecting ring 13 is placed into the connecting groove 12 at the top of the mounting sleeve 2. During this process, the limiting block 9 is pulled to drive the movable rod 8 and the positioning plug 10 to retract outward against the elastic force of the connecting spring 11. When the connecting ring 13 is placed in the appropriate position, the limiting block 9 is released, the connecting spring 11 returns to its deformation, and the movable rod 8 is pushed so that the positioning plug 10 is inserted into the positioning connecting holes 14 on both sides of the connecting ring 13.

[0022] The mounting sleeve 2 has a connecting groove 15 in the middle, and a first sealing and limiting groove 16 is formed on the inner wall of the connecting groove 15. A second sealing and limiting groove 17 is formed on the inner wall of the connecting groove 12. The bottom end of the mounting sleeve 3 is located inside the connecting ring 13 and a connecting tube 18 is fixedly installed. A first sealing ring 19 is fixedly installed on the outer end of the connecting ring 13, and a second sealing ring 20 is fixedly installed on the outer end of the connecting tube 18. A connecting wire 21 is fixedly installed on the bottom end of the temperature sensor body 1. The connecting wire 21 is electrically connected to the temperature sensor body 1. The first sealing ring 19 on the outer end of the connecting ring 13 will be inserted into the second sealing and limiting groove 17 on the inner wall of the connecting groove 12, and the second sealing ring 20 on the outer end of the connecting tube 18 will be inserted into the first sealing and limiting groove 16 on the inner wall of the connecting groove 15, forming a double seal.

[0023] Working Principle: When using a temperature sensor with a sealed structure, the first step is installation. The positioning rod 6 at the bottom of the mounting sleeve 3 is aligned with the positioning hole 5 at the top of the mounting sleeve 2 and inserted to complete initial positioning, thus initially connecting the mounting sleeve 3 and the mounting sleeve 2. Simultaneously, the connecting ring 13 is placed into the connecting groove 12 at the top of the mounting sleeve 2. During this process, pulling the limiting block 9 causes the movable rod 8 and the positioning block 10 to retract outwards against the elastic force of the connecting spring 11. Once the connecting ring 13 is in the appropriate position, the limiting block 9 is released, the connecting spring 11 returns to its original shape, and the movable rod 8 is pushed, causing the positioning block 10 to insert into the positioning connecting holes 14 on both sides of the connecting ring 13. This stably connects the mounting sleeve 2 and the mounting sleeve 3, achieving the installation and fixation of the probe 4 and the temperature sensor body 1. During the connection and installation process, the sealing structure functions synchronously. The first sealing ring 19 at the outer end of the connecting ring 13 will be inserted into the second sealing limiting groove 17 on the inner wall of the connecting groove 12, and the second sealing ring 20 at the outer end of the connecting tube 18 will be inserted into the first sealing limiting groove 16 on the inner wall of the connecting through groove 15, forming a double seal, effectively preventing external moisture, dust and other impurities from entering the temperature sensor body 1. When the temperature sensor body 1 starts to work, the probe 4 is responsible for sensing the external temperature. The temperature sensor body 1 adopts the PT100 model, which converts the temperature signal into an electrical signal or other measurable signal. These signals are transmitted to the processing circuit inside the temperature sensor body 1 through the internal circuit. After analysis and conversion by the processing circuit, the processed signal is finally transmitted to external devices, such as display devices, control systems, etc., by the connecting wire 21 at the bottom of the temperature sensor body 1, so as to realize the detection of temperature and signal output.

[0024] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
