Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of temperature equipment calibration, in particular to a constant temperature tooling. Background Art
[0002] Temperature sensors and temperature recorders with built-in temperature probes are usually calibrated using the standard instrument comparison method. During the calibration process, a constant temperature device is used to provide a constant temperature field, such as a constant temperature bath with a liquid as the constant temperature medium or a constant temperature box with a gas as the constant temperature medium. Since the temperature uniformity and fluctuation performance of the liquid medium temperature field are better than the gas medium temperature field, most of the existing methods use a constant temperature bath to calibrate temperature sensors and temperature recorders.
[0003] Since the liquid medium of the thermostatic bath is usually silicone oil, water, alcohol, etc., the temperature sensor with poor sealing at the temperature measuring end and the temperature recorder with its own temperature probe cannot be placed directly in the liquid thermostatic medium of the thermostatic bath. A protective sleeve is required to isolate the sensor or recorder from the thermostatic medium to prevent damage to the temperature sensing element of the temperature sensor and the internal components of the temperature recorder. Existing staff often use glass tubes as protective sleeves, place the temperature sensor that needs to be calibrated and the temperature recorder with its own temperature probe in the glass tube, and then put it into the thermostatic bath.
[0004] However, the temperature inside the glass tube is uneven, which causes the data detected by the temperature sensor and the temperature recorder with its own temperature probe to be inaccurate with the data detected by the temperature detection device, resulting in the calibrated temperature sensor and the temperature recorder with its own temperature probe not being able to meet the use requirements. In order to improve the temperature uniformity in the glass tube, the staff will put the glass tube into the constant temperature bath for a period of time before reading the test data, which results in a lot of time spent waiting and low calibration efficiency.
[0005] Therefore, a constant temperature tooling is urgently needed to solve the above technical problems. Utility Model Content

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.
[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0032] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0033] The constant temperature tooling provided in this embodiment can solve the problem in the prior art that for larger equipment, the uniformity of heat in the placement space cannot be guaranteed, resulting in the inability to compare the temperature data measured by the calibrated part and the comparison temperature part, and the calibration work cannot be carried out. A long wait is required before the internal temperature becomes uniform, and the calibration work is time-consuming and inefficient.
[0034] like Figure 1 and Figure 2As shown, this embodiment provides a constant temperature tooling, part of which is placed in a constant temperature bath (not shown in the figure), and the temperature of the liquid medium in the constant temperature bath will be transferred to the inside of the constant temperature tooling, so that the temperature piece to be calibrated (not shown in the figure) placed inside the constant temperature tooling detects its internal temperature. The constant temperature tooling includes a heat pipe 1, a baffle 2, an insulation plug 3, a circulation piece 4 and a comparative temperature piece (not shown in the figure), wherein the heat pipe 1 is a cylindrical shape with one end open, and the temperature piece to be calibrated is placed inside the heat pipe 1 to detect the temperature inside the heat pipe 1. The detection end of the comparative temperature piece is placed in the heat pipe 1 to detect the internal temperature of the heat pipe 1. The baffle 2 is arranged around the outer periphery of the open end of the heat pipe 1. When the staff puts the heat pipe 1 in the constant temperature bath, the baffle 2 abuts against the end face of the opening of the constant temperature bath, so that the staff can subsequently take the heat pipe 1 and its internal components from the constant temperature bath. The insulation plug 3 is blocked at the opening of the heat pipe 1 to maintain the temperature inside the heat pipe 1 stable and prevent it from being affected by the external environment. The circulation part 4 is placed inside the heat pipe 1. The circulation part 4 can make the air inside the heat pipe 1 flow, so that the temperature of each place inside the heat pipe 1 can be quickly balanced, ensuring that the temperature part to be calibrated and the comparison temperature part are tested in the same temperature environment, thereby ensuring the accuracy of the calibration of the temperature part to be calibrated.
[0035] The calibration principle of the part to be calibrated is as follows: the temperature part to be calibrated and the comparison temperature part are both used to detect the temperature inside the heat pipe 1. Under the action of the circulation part 4, the temperature at various places inside the heat pipe 1 can be made equal. Under the same temperature environment, the temperature data detected by the temperature part to be calibrated may be different from the temperature data detected by the comparison temperature part. The staff compares the difference in temperature data between the two, and adjusts the temperature part to be calibrated according to the data of the comparison temperature part, thereby completing the calibration of the temperature part to be calibrated.
[0036] In this embodiment, the thermostatic tool further includes a rack 5, which is placed in the heat pipe 1, and the thermometer to be calibrated is placed on the rack 5 to ensure that the temperature piece to be calibrated is stably placed in the heat pipe 1. Preferably, the rack 5 is provided with a plurality of placement layers 51 in the height direction, and each placement layer 51 can be used to place the temperature piece to be calibrated, so that the staff can complete the calibration of a plurality of temperature pieces to be calibrated at one time, thereby improving the work efficiency.
[0037] Exemplarily, the circulation part 4 includes a fan 41 and a power supply 42, wherein the fan 41 is located in the heat pipe 1 to realize the air flow in the heat pipe 1 and ensure the temperature balance in various places in the heat pipe 1. The fan 41 is preferably arranged at the bottom of the heat pipe 1 to avoid friction between the fan 41 and the rack 5. The power supply 42 is arranged on the baffle 2 and located outside the heat pipe 1, which can effectively ensure the service life of the power supply 42 and leave more placement space for the heat pipe 1. Specifically, the fan 41 and the power supply 42 are electrically connected through a wire.
[0038] In this embodiment, a first through hole and a second through hole are provided on the insulation plug 3, wherein the wire passes through the first through hole and is connected to the power source 42, so that the wiring of the wire can be more concise. The comparison temperature piece is inserted in the second through hole, and its detection end is placed in the heat pipe 1, so that the comparison temperature piece does not occupy too much placement space of the heat pipe 1, so that more temperature pieces to be calibrated can be placed in the heat pipe 1, thereby improving the work efficiency of the staff. Exemplarily, the comparison temperature piece is a columnar thermometer to ensure that it can be inserted in the second through hole.
[0039] In this embodiment, the heat pipe 1 and the baffle 2 can be detachably connected so that the staff can replace the baffle 2 according to the size of the thermostatic bath slot, thereby improving the flexibility of the thermostatic tooling. For example, an external thread is provided on the outer wall of the heat pipe 1, a center hole is provided on the baffle 2, the heat pipe 1 is inserted into the center hole, and an internal thread is provided on the inner wall of the center hole, so that the heat pipe 1 and the baffle 2 are threadedly connected. The staff twists the heat pipe 1 forward relative to the baffle 2 to connect the two, and twists the heat pipe 1 reversely relative to the baffle 2 to separate the two.
[0040] In this embodiment, the heat pipe 1 is made of metal, so that the temperature of the thermostatic bath can be quickly transferred to the inside of the heat pipe 1. At the same time, the service life of the heat pipe 1 can be guaranteed. The heat insulating plug 3 is made of high temperature resistant rubber, so that the heat insulating plug 3 can be completely sealed with the open end of the heat pipe 1, effectively maintaining the internal temperature of the heat pipe 1.
[0041] Preferably, the constant temperature tooling also includes a display screen, wherein the temperature component to be calibrated and the comparison temperature component are both electrically connected to the display screen, and the display screen can simultaneously display the temperature data detected by the temperature component to be calibrated and the temperature data detected by the comparison temperature component, so that the staff can quickly and conveniently know the temperature data detected by the temperature component to be calibrated and the temperature data detected by the comparison temperature component, and perform calibration. The display screen setting is a conventional technical means and does not belong to the key protection content of the present utility model.
[0042] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
