Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology, and more specifically, to a temperature measuring structure device with an adjustable probe for measuring the temperature field inside a cavity. Background Technology

[0002] In industrial and experimental equipment such as large ovens, environmental test chambers, or heating chambers of non-combustible heating devices, accurately understanding the temperature distribution (i.e., temperature field) at any location within the internal space is crucial for optimizing process parameters, ensuring product quality, and evaluating equipment performance.

[0003] Currently, measuring the temperature field inside such cavities typically involves inserting a temperature probe through a pre-drilled hole or opening in the cavity. However, this method makes probe positioning extremely difficult, hindering precise and repeatable movement to specific three-dimensional coordinate points within the cavity. Operators often have to make estimations, resulting in low accuracy and poor repeatability of the measurement data, failing to accurately reflect the true and detailed temperature field distribution inside the cavity. To achieve multi-point measurements, multiple fixed probes need to be deployed, which is costly and inflexible.

[0004] Therefore, how to provide a device that can be easily installed in the cavity to be tested and whose probe position can be precisely fine-tuned to achieve precise measurement of the temperature field inside the cavity has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to provide a temperature measurement structure device with an adjustable probe, in order to solve the problem in the prior art of accurately locating and finely adjusting the temperature field inside the cavity.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A temperature measuring structure device with an adjustable probe includes: a base adapted to fix the device to a cavity to be measured, the base having an axial groove extending along a first direction; an axial adjustment mechanism including a first slider slidable within the axial groove and an axial drive member for driving the first slider to move along the first direction; a radial adjustment mechanism including a column fixed to the first slider, the column having at least one radial slide rail extending along a second direction perpendicular to the first direction; and at least one temperature probe mounted on the column via a second slider slidable within the radial slide rail, the second slider having a fastener for locking it.

[0008] The technical solution provided by this utility model offers a stable reference platform for measurement through a base that can be fixed inside the cavity to be measured. On this platform, an axial drive component drives a column fixed on a first slider to move within an axial groove in the base, achieving precise fine-tuning of the probe in a first direction (e.g., horizontal). The sliding and locking of a second slider within a radial rail on the column enables precise positioning of the probe in a second direction (e.g., vertical). This two-dimensional coordinate positioning and adjustment method greatly improves the positioning accuracy and repeatability of the measurement, enabling convenient and low-cost scanning and mapping of the fine temperature field inside the cavity.

[0009] Optionally, the axial groove is a T-shaped groove with the opening facing upward, and the column passes through the opening of the T-shaped groove.

[0010] It is evident that this structure not only provides good guidance and limitation for the first slider, but also reserves space for the movement of the column.

[0011] Optionally, the axial drive component is a lead screw; the first slider has an axial through-hole that mates with the lead screw thread.

[0012] It is evident that smooth and precise displacement adjustment can be achieved through the transmission method of the lead screw and nut.

[0013] Optionally, an adjustment knob is provided at the end of the lead screw.

[0014] As can be seen, an adjustment knob is provided at the end of the lead screw for easy manual operation by the user.

[0015] Optionally, the radial slide rail includes two parallel longitudinal slide grooves that are internally interconnected; the second slider is slidably disposed in one of the longitudinal slide grooves, and the second slider has a screw hole, the opening of which is opposite to the opening of the other longitudinal slide groove; the fastener is a fastening bolt, which passes through the other longitudinal slide groove and is threadedly connected to the screw hole.

[0016] As can be seen, this design cleverly utilizes two sliding grooves to achieve the functions of probe insertion, guidance, and locking, resulting in a reliable structure and convenient operation.

[0017] Optionally, the temperature probe is a strip or columnar structure; the second slider has a mounting hole for inserting and fixing the temperature probe, and the outer periphery of the middle section of the temperature probe is wrapped inside the mounting hole.

[0018] As can be seen, this design ensures a stable connection between the probe and the slider.

[0019] Optionally, it includes multiple temperature probes, each of which is mounted on the column via its own second slider and is spaced apart along the extension direction of the radial slide rail.

[0020] As can be seen, multiple temperature probes can simultaneously measure the temperature of different horizontal surfaces, significantly improving the efficiency of temperature field measurement.

[0021] Optionally, the base is provided with positioning holes for positioning the device.

[0022] As can be seen, the positioning hole enables the device to be fixedly connected to the positioning fitting in the chamber to be tested.

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0033] Please see Figures 1 to 2 This invention provides a temperature measurement structure device with an adjustable probe. The device is designed to be installed inside a larger chamber (such as an oven or environmental chamber) to perform precise scanning and measurement of the internal temperature field.

[0034] The device includes a base 1. Positioning holes 8 are provided at the four corners of the base 1 for positioning the device, through which the device can be fixedly connected to a positioning fitting within the chamber to be tested. The base 1 also has an axial groove 10 extending along a first direction (e.g., horizontal direction). In this embodiment, the axial groove 10 is a T-shaped groove with its opening facing upwards.

[0035] The axial adjustment mechanism is used to drive the subsequent temperature measuring component to move along a first direction. It includes a first slider 11 that slides in conjunction with an axial groove 10, and an axial drive member 3. The bottom end of the first slider 11 is shaped to match a T-slot, allowing it to be contained and move smoothly within the groove. An axially penetrating threaded hole is provided on the first slider 11. In this embodiment, the axial drive member 3 is a lead screw, whose thread engages with the threaded hole 2 on the first slider 11. An adjustment knob 12 for easy manual operation is provided at the end of the lead screw. Rotating the adjustment knob 12 drives the first slider 11 to perform a smooth and precise horizontal displacement via the lead screw transmission.

[0036] The radial adjustment mechanism 4 is a column, the lower end of which is fixed to the first slider 11 and passes through the T-slot opening of the base 1. A longitudinal groove serving as a radial slide rail 5 is formed on the column 4 along the second direction (i.e., the vertical direction). In this preferred embodiment, the radial slide rail 5 includes two parallel longitudinal grooves that are internally interconnected.

[0037] At least one temperature probe 7 is mounted on the column 4 via a second slider 6. The temperature probe 7 is a slender strip or columnar structure. The second slider 6 has a mounting hole for inserting and fixing the temperature probe 7. The middle section of the temperature probe 7 passes through the mounting hole, and its outer periphery is wrapped by the inner wall of the mounting hole, thereby achieving a stable connection.

[0038] The second slider 6 is slidably disposed within one of the longitudinal grooves for guidance, and has a screw hole on it, the opening of which faces the opening of the other longitudinal groove. The fastener 9, in this embodiment, is a fastening bolt, the shank of which passes through the other longitudinal groove and is threadedly connected to the screw hole on the second slider 6. When it is necessary to fix the probe at a certain height, simply tighten the fastening bolt 9. As the bolt is screwed into the second slider 6, it pulls the second slider 6 outward, causing the outer wall of the second slider 6 to abut against the inner wall of the guiding longitudinal groove. This frictional force securely locks the second slider 6 in that radial position. This embodiment shows three temperature probes 7, each mounted via an independent second slider 6, which can be independently adjusted and locked on the radial slide rail 5.

[0039] The method of using this device is as follows: First, according to the measurement requirements, fix the entire device in an appropriate position inside the cavity to be measured through the positioning hole 8 on the base 1. Then, by rotating the adjustment knob 12, drive the column 4 to adjust the overall horizontal position. Finally, move and lock each second slider 6 up and down to complete its precise vertical positioning. In this way, the sensing ends of one or more probes can be precisely positioned at any target coordinate point inside the cavity, thereby performing high-precision temperature field measurement.

[0040] In summary, this utility model integrates the axial adjustment mechanism and the radial adjustment mechanism onto a fixed base to form an independent intracavity temperature measurement module, which ingeniously solves the problem of the difficulty in the existing technology to accurately and repeatably measure the temperature field inside the cavity. It has the advantages of compact structure, accurate positioning, and flexible use.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
