Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature sensor equipment technology, specifically a telescopic temperature sensor. 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] The probe length of commonly used temperature sensors is not adjustable, making them difficult to adapt to various measurement environments and unable to accurately detect the temperature at different depths in pipes or tanks, thus producing errors. Furthermore, when installed with different types of pipes or tanks, temperature sensors with different types of flanges and bolts are required, resulting in resource waste.
[0004] Therefore, those skilled in the art have provided a retractable temperature sensor to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to provide a retractable temperature sensor to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A telescopic temperature sensor includes a temperature sensor body, a telescopic mechanism, and a mounting mechanism. The bottom of the temperature sensor body is fixedly connected to a housing, and a probe is slidably connected inside the housing. A wire harness connects the temperature sensor body and the probe. The mounting mechanism is provided on the outer wall of the housing, and a fixing sleeve is fixedly connected to the outer wall of the housing. The telescopic mechanism is provided between the fixing sleeve and the probe.
[0008] As a further embodiment of this utility model: an external thread is fixedly connected to the lower part of the outer side wall of the housing, and a mounting flange is threadedly connected to the upper end of the external thread. A locking ring is abutted against the bottom of the mounting flange and the locking ring is threadedly connected to the external thread.
[0009] As a further embodiment of this utility model: a locking ring is fixedly connected to the outer wall of the housing and the locking ring is located above the external thread, and the locking ring abuts against the mounting flange.
[0010] As a further improvement of this utility model: the outer wall of the probe is provided with multiple sets of slots and the slots are arranged at equal intervals with the adjacent slots, and the outer wall of the housing is provided with a through groove and the through groove is set perpendicular to the adjacent slot.
[0011] As a further embodiment of this utility model: a sliding groove is provided at the top of the inside of the fixed sleeve, a slider is slidably connected in the sliding groove, an L-shaped locking rod is fixedly connected to the bottom of the slider, a return spring is fixedly connected between the L-shaped locking rod and the inner wall of the fixed sleeve, and the L-shaped locking rod is movably engaged with the adjacent locking groove and through groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] Equipped with a telescopic mechanism, the connection between the housing and the probe can be quickly unlocked by pulling the L-shaped lever inside the fixed sleeve and utilizing the sliding connection between the slider and the groove, allowing for easy telescopic adjustment. After adjustment, the L-shaped lever is re-engaged into the corresponding slot and through groove by the action of the return spring, ensuring that the probe position is accurately fixed and preventing loosening or displacement after adjustment. No additional tools are required; adjustment can be completed with simple pulling and releasing operations, saving tool usage time and space, making it suitable for use in fast-paced situations and improving work efficiency. Equipped with an installation mechanism, different mounting flanges can be used to flexibly adjust the sensor according to the specifications and requirements of the pipeline, ensuring that the temperature sensor can be adapted to different types of pipelines. First, unscrew the locking ring, then rotate the mounting flange to the end of the external thread and fix it, thereby ensuring the firmness of the flange connection to the pipeline and the stability of the sensor installation.

[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] Example 1
[0021] Reference Figure 1-4 This embodiment provides a telescopic temperature sensor, including a temperature sensor body 1, a housing 2, a probe 3, a fixing sleeve 4, a slot 5, a through groove 6, an L-shaped locking rod 7, a return spring 8, a slider 9, a sliding groove 10, an external thread 11, a locking ring 12, a mounting flange 13, and a fixing baffle 14; the bottom end of the temperature sensor body 1 is fixedly connected to the housing 2, the probe 3 is slidably connected inside the housing 2, a wire harness is connected between the temperature sensor body 1 and the probe 3, an installation mechanism is provided on the outer wall of the housing 2, a fixing sleeve 4 is fixedly connected to the outer wall of the housing 2, and a telescopic mechanism is provided between the fixing sleeve 4 and the probe 3.
[0022] Example 2
[0023] Reference Figure 1 , 4 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that an external thread 11 is fixedly connected to the lower part of the outer side wall of the housing 2, and a mounting flange 13 is threadedly connected to the upper end of the external thread 11. A locking ring 12 is abutted against the bottom of the mounting flange 13 and is threadedly connected to the external thread 11. The locking ring 12 is fixedly connected to the outer side wall of the housing 2 and is located above the external thread 11. The locking ring 12 abuts against the mounting flange 13.
[0024] When installing the temperature sensor body 1, different mounting flanges 13 are used depending on the different pipes. First, the locking ring 12 can be unscrewed according to the threaded connection with the external thread 11. Then, the mounting flange 13 can be unscrewed according to the threaded connection with the external thread 11 and replaced with a matching flange for installation. The replaced mounting flange 13 is rotated to the end of the external thread 11 and fully abuts against the fixed retainer 14. Finally, the locking ring 12 is fixed to the bottom of the mounting flange 13 to complete the replacement.
[0025] Example 3
[0026] Reference Figure 1 , 23. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the outer wall of the probe 3 has multiple sets of slots 5 and the slots 5 are arranged at equal intervals with adjacent slots 5. The outer wall of the housing 2 has a through groove 6 and the through groove 6 is perpendicular to the adjacent slots 5. The top of the inside of the fixing sleeve 4 has a sliding groove 10. A slider 9 is slidably connected in the sliding groove 10. An L-shaped locking rod 7 is fixedly connected to the bottom of the slider 9. A return spring 8 is fixedly connected between the L-shaped locking rod 7 and the inner wall of the fixing sleeve 4. The L-shaped locking rod 7 is movably engaged with the adjacent slots 5 and the through groove 6.
[0027] When the length needs to be adjusted, pull the L-shaped lever 7 inside the fixing sleeve 4 and slide the slider 9 at the upper end of the L-shaped lever 7 into the sliding groove 10 inside the fixing sleeve 4. This will disengage the L-shaped lever 7 from the slot 5 and the through groove 6, thus unlocking the housing 2 and the probe 3. Then pull the probe 3 to extend or retract it to the required length. After adjustment, release the L-shaped lever 7 and reset it using the return spring 8 at the rear end of the L-shaped lever 7. This will allow the L-shaped lever 7 to re-engage into the corresponding slot 5 and the through groove 6, thus fixing the position of the probe 3.
