Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, specifically to a temperature sensor that can be installed stably. 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 and come in a wide variety. They can be broadly classified into two categories based on the measurement method: contact and non-contact. Based on the sensor materials and electronic component characteristics, they are further divided into resistance temperature detectors (RTDs) and thermocouples.

[0003] Most existing temperature sensors are connected to the housing by threads. However, the connection between the threaded joint and the probe is welded, which can lead to leakage at the joint after prolonged use. In addition, existing temperature sensors do not have a support mechanism. When the temperature sensor head is hit, the impact can also cause damage to the joint and may even cause the probe to bend. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a temperature sensor that is stable to install, possesses the advantages of stability and sealing, and solves the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a temperature sensor with stable installation, including an electrical component housing, a probe rod installed at the bottom of the electrical component housing, a connecting bolt fixedly mounted on the outer edge of the probe rod, a hexagonal block fixedly mounted on the top of the connecting bolt, a right sealing shell and a left sealing shell provided on the outer wall of the top of the connecting bolt, a top sealing ring and a bottom sealing ring respectively provided on the inner walls of the top and bottom of the right sealing shell and the left sealing shell, and a fixed suction cup provided on both sides of the electrical component housing, with a connecting rod movably connected to the inner wall of the top of the fixed suction cup.

[0006] As a preferred embodiment of this utility model, the inner walls of the right sealing housing and the left sealing housing and the outer wall of the connecting bolt are all provided with bottom mounting grooves, the inner walls of the right sealing housing and the left sealing housing and the outer wall of the probe rod are all provided with top mounting grooves, the top sealing ring is installed in the top mounting groove, and the bottom sealing ring is installed in the bottom mounting groove.

[0007] As a preferred embodiment of this utility model, a central sealing gasket is provided between the right sealing housing and the left sealing housing, and the right sealing housing and the left sealing housing are fixed together by fixing bolts.

[0008] As a preferred embodiment of this utility model, an internal threaded block is fixedly assembled on the outer wall of the electrical component housing, and a threaded rod is threadedly connected to the inner wall of the internal threaded block, and the threaded rod is rotatably connected to the connecting rod.

[0009] As a preferred embodiment of this utility model, the bottom of the internal threaded block is provided with a limiting block, and the connecting rod is movably sleeved with the limiting block.

[0010] As a preferred embodiment of this utility model, the right sealing shell and the left sealing shell are made of aluminum alloy.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This stable temperature sensor uses a right and left sealing housing to enclose the joint between the probe rod and the connecting bolt. The right and left sealing housings are sealed to the connecting bolt and the left sealing housing through top and bottom sealing rings, preventing leakage even when gaps appear at the joint between the probe rod and the connecting bolt. This solves the problem of leakage at the joint caused by welding at the threaded joint of the existing temperature sensor, which occurs after long-term use.

[0013] 2. This stable temperature sensor is mounted by attaching a fixed suction cup to the housing, and then supporting the electrical component housing through a connecting rod, threaded rod, internal threaded block, and limiting block. When an impact is encountered, the suction force of the fixed suction cup can stably position the electrical component housing, thus solving the problem that existing temperature sensors do not have a support mechanism, and the probe rod is easily bent when the temperature sensor head is impacted.

[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 Figure 1 - Figure 5 A temperature sensor with stable installation includes an electrical component housing 1. A probe 2 is mounted on the bottom of the electrical component housing 1. A connecting bolt 3 is fixedly mounted on the outer edge of the probe 2. A hexagonal block 4 is fixedly mounted on the top of the connecting bolt 3. A right sealing shell 5 and a left sealing shell 6 are provided on the outer wall of the top of the connecting bolt 3. A top sealing ring 10 and a bottom sealing ring 9 are respectively provided on the inner walls of the top and bottom of the right sealing shell 5 and the left sealing shell 6. Fixing suction cups 17 are provided on both sides of the electrical component housing 1. A connecting rod 16 is movably connected to the inner wall of the top of the fixing suction cup 17. Through the setting of the right sealing shell 5 and the left sealing shell 6, the right sealing shell 5 and the left sealing shell 6 can hold the connecting bolt. The joint between the probe rod 2 and the detector rod 3 is wrapped, and the gap between the right sealing housing 5 and the left sealing housing 6 and the connecting bolt 3 is sealed by the bottom sealing ring 9. Then, the gap between the right sealing housing 5 and the left sealing housing 6 and the detector rod 2 is sealed by the top sealing ring 10. In this way, if there is a gap between the detector rod 2 and the connecting bolt 3, the right sealing housing 5 and the left sealing housing 6 can play a sealing role, which improves the sealing performance of the device. During installation, the fixing suction cup 17 is attached to the box, and then the fixing suction cup 17 is supported by the connecting rod 16. When the electrical component housing 1 is impacted, the detector rod 2 will not bend, which improves the stability of the device.

[0022] In a preferred embodiment, bottom mounting grooves 7 are provided on the inner walls of the right sealing housing 5 and the left sealing housing 6 and on the outer wall of the connecting bolt 3, and top mounting grooves 8 are provided on the inner walls of the right sealing housing 5 and the left sealing housing 6 and on the outer wall of the probe rod 2. The top sealing ring 10 is installed in the top mounting groove 8, and the bottom sealing ring 9 is installed in the bottom mounting groove 7. By setting the bottom mounting groove 7 and the top mounting groove 8, the bottom mounting groove 7 and the top mounting groove 8 can respectively limit the bottom sealing ring 9 and the top sealing ring 10, so that the bottom sealing ring 9 and the top sealing ring 10 cannot be displaced, thereby further improving the sealing performance of the device.

[0023] In a preferred embodiment, a central sealing gasket 11 is provided between the right sealing housing 5 and the left sealing housing 6. The central sealing gasket 11 seals the gap between the right sealing housing 5 and the left sealing housing 6. The right sealing housing 5 and the left sealing housing 6 are fixed together by fixing bolts 12. The fixing bolts 12 make the right sealing housing 5 and the left sealing housing 6 detachable, which facilitates the observation of the gap between the probe rod 2 and the connecting bolt 3 and facilitates timely maintenance.

[0024] In a preferred embodiment, an internal threaded block 13 is fixedly mounted on the outer wall of the electrical component housing 1. A threaded rod 15 is threadedly connected to the inner wall of the internal threaded block 13. The threaded rod 15 is rotatably connected to the connecting rod 16. By rotating the threaded rod 15, the threaded rod 15 rotates within the internal threaded block 13. At this time, the rotation of the threaded rod 15 pushes the connecting rod 16 and the fixed suction cup 17 to move downward, so that the fixed suction cup 17 can be attracted to the housing. At this time, the electrical component housing 1 cannot shake when subjected to external force.

[0025] In a preferred embodiment, a limiting block 14 is provided at the bottom of the internal thread block 13, and the connecting rod 16 is movably sleeved with the limiting block 14. By setting the limiting block 14, the limiting block 14 plays a limiting role on the connecting rod 16, so that the connecting rod 16 can only run vertically, thereby improving the stability of the device.

[0026] In a preferred embodiment, the right sealing housing 5 and the left sealing housing 6 are made of aluminum alloy. Taking advantage of the high corrosion resistance of aluminum alloy, when leakage occurs between the probe 2 and the connecting bolt 3, the right sealing housing 5 and the left sealing housing 6 are not easily corroded by the leaked liquid, thus increasing the service life of the device.

[0027] Working principle: During use, tighten the connecting bolts 3 into the housing, then install the bottom sealing ring 9 on the bottom mounting groove 7 and the top sealing ring 10 on the top mounting groove 8. Next, align the bottom mounting groove 7 and top mounting groove 8 on the left sealing housing 6, and align the bottom sealing ring 9 and top sealing ring 10. Then, attach the left sealing housing 6 to the connecting bolts 3. Next, install the middle sealing gasket 11 on the left sealing housing 6, and then align the right sealing housing 5 with the left sealing housing 6. Finally, secure the right sealing housing 5 and left sealing housing 6 together using the fixing bolts 12. After the sealing mechanism is installed, the threaded rod 15 is rotated so that it rotates in the internal thread block 13. At this time, the threaded rod 15 pushes the connecting rod 16 downward, and the connecting rod 16 slides in the limiting block 14, gradually causing the fixed suction cup 17 to adhere to the housing. At this time, the stabilizing structure is installed. When the electrical component housing 1 is subjected to external force, the fixed suction cup 17, connecting rod 16, threaded rod 15, internal thread block 13 and limiting block 14 provide stable support for the electrical component housing 1, so that the electrical component housing 1 will not shake.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
