Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, specifically to a temperature sensor that is easy to install. Background Technology

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments. There are many types of temperature sensors, which can be divided into two main categories according to the measurement method: contact type and non-contact type. According to the characteristics of sensor materials and electronic components, they can be divided into two categories: resistance temperature detectors (RTDs) and thermocouples.

[0003] As disclosed in the patent announcement CN220819242U, an easy-to-install temperature sensor includes a temperature sensor and an installation mechanism. The installation mechanism is provided on the surface of the temperature sensor. A junction box is fixedly connected to one end of the temperature sensor. A fixing mechanism is provided on one end surface of the junction box. A top cover is fixedly connected to one side surface of the fixing mechanism. A wiring port is fixedly connected to one side surface of the junction box. A wire-binding mechanism is provided on one side surface of the wiring port. The beneficial effects of this utility model are as follows: By setting the installation mechanism, a suitable position can be selected according to the working environment. Then, the temperature sensor is inserted into the interior of the device to be installed. Threads are then made into the inner wall of the hole on the surface of the device to be installed. The sensor is then threadedly connected to the device through fastening bolts, positioning holes, and the hole. This allows for installation of the temperature sensor according to specific usage requirements. The threaded connection is convenient and quick, improving the installation efficiency of the temperature sensor.

[0004] Although the aforementioned patent allows for threaded connection to the installed equipment via fastening bolts, positioning holes, and openings, the temperature sensor is fixed via a pre-set connecting block and positioning hole. This requires the installed equipment to precisely drill matching threaded holes; otherwise, installation is impossible. If the hole position of the installed equipment is off or the spacing is incorrect, re-drilling or adjustment is required, reducing installation efficiency. Utility Model Content

[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution:

[0024] An easy-to-install temperature sensor includes a junction box 1, to which a vertical thermocouple sheath 2 is fixedly connected at the bottom center. A horizontal fixing plate 3 is fixedly connected to the upper middle part of the thermocouple sheath 2. An adjustment mechanism is provided between the fixing plate 3 and the thermocouple sheath 2. The adjustment mechanism includes a threaded groove 7 formed on the outer wall of the upper end of the thermocouple sheath 2, and a movable sleeve 8 threadedly connected to the outside of the threaded groove 7. A fixed sleeve 9 is movably connected to the bottom end of the movable sleeve 8. The adjustment mechanism also includes movable grooves 10 symmetrically formed on both sides of the middle of the fixing plate 3, and mounting sleeves 11 movably installed inside the movable grooves 10. The upper ends of the two mounting sleeves 11 facing each other and the outer middle part of the fixed sleeve 9 are fixed. A horizontal fixing block 12 is connected, and a connecting rod 13 is rotatably connected between the fixing block 12 and the fixing sleeve 9 via a rotating shaft. A limiting groove 14 is opened circumferentially at the upper end of the fixing sleeve 9, and a limiting ring 15 is arranged circumferentially at the bottom end of the movable sleeve 8. The limiting ring 15 is slidably connected to the limiting groove 14. Guide grooves 16 are opened inwardly on both sides of the inner wall of the movable groove 10. Guide blocks 17 that are slidably connected to the guide grooves 16 are fixedly connected to both sides of the outer wall of the mounting sleeve 11. The cross-section of the limiting ring 15 and the limiting groove 14 is L-shaped. A cover 4 is threadedly connected to the top of the junction box 1. A horizontal cable conduit 5 is integrally formed on the right side of the junction box 1. A sealing head 6 is threadedly connected to the right side of the cable conduit 5.

[0025] In this embodiment, the adjustment of the spacing of the mounting sleeve 11 is achieved through the threaded engagement of the movable sleeve 8 and the threaded groove 7, and the sliding engagement of the limiting ring 15 and the limiting groove 14. This achieves the effect of quickly adapting to different mounting hole spacings and solves the problem of re-processing mounting holes due to hole position deviation in the prior art.

[0026] Working principle: When it is necessary to align with the mounting holes on the device being installed, the movable sleeve 8 is rotated to move axially along the threaded groove 7 at the upper end of the thermocouple sheath 2. The limiting ring 15 at the bottom of the movable sleeve 8 slides within the limiting groove 14 at the upper end of the fixed sleeve 9, simultaneously causing the fixed sleeve 9 to move axially along the thermocouple sheath 2. The movement of the fixed sleeve 9 pushes the fixing blocks 12 on both sides of the mounting sleeve 11 through the connecting rod 13, causing the mounting sleeve 11 to slide outward or inward synchronously along the guide grooves 16 in the movable grooves 10 on both sides of the fixed plate 3, thereby changing the distance between the two mounting sleeves 11 to match the preset mounting hole position on the device being installed. After the distance between the mounting sleeves 11 is adjusted to the correct position, fasteners are used to fix the mounting sleeves 11 to the device being installed. When wiring, the cover 4 is opened, the wire is inserted into the junction box 1, and then the cover 4 is tightened to achieve a seal. The wire is led out through the conduit 5 and the pipe opening is sealed with the sealing head 6 to ensure the sealing and stability of the overall structure.

[0027] It should be noted that a temperature sensing component is installed inside the thermocouple sheath 2, which includes a thermocouple sensing element and a signal transmission wire. The thermocouple sensing element is fixedly installed inside the thermocouple sheath 2, and the signal transmission wire is led out from the thermocouple sensing element and extends into the junction box 1. When the thermocouple sheath 2 comes into contact with the medium being measured, the thermocouple sensing element transmits the detected temperature signal to the signal processing circuit in the junction box 1 through the signal transmission wire, and then outputs it to the external control system through the cable led out from the conduit 5.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
