[0043] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0044] 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.

[0045] 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. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. 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.

[0046] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships 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.

[0047] In the prior art, temperature sensors are usually directly bundled and fixed in the box of the temperature field equipment to facilitate the temperature uniformity test of the temperature field equipment. In the case of testing multiple temperature field equipment in sequence, after the preceding equipment completes the test, the temperature sensor needs to be disassembled, and then the disassembled temperature sensor is re-bundled and arranged in the subsequent equipment, which greatly reduces the arrangement and recovery speed of the temperature sensor in the box. In addition, by directly bundling and fixing the temperature sensor at the required position of the box, the flexibility of installing and fixing the temperature sensor is poor.

[0048] In order to solve the above problems, Figure 1 to Figure 3 As shown, the present embodiment provides a test bracket 10, which is used to fix a temperature sensor in a box 20. The test bracket 10 includes a bracket assembly 1 and a mounting assembly 2, wherein the bracket assembly 1 is used to be arranged in the box 20 of the temperature field device, and the mounting assembly 2 is mounted and fixed with a temperature sensor, and the mounting assembly 2 can be selectively detachably connected to one of the bracket assembly 1 and the inner wall 201 of the box 20. The present embodiment fixes the temperature sensor in the box 20 by setting the test bracket 10, and there is no need to directly bind and fix the temperature sensor in the box 20, and after completing the test of the temperature in the current box 20, there is no need to disassemble the temperature sensor, and the temperature sensor can be transferred together with the test bracket 10 to the next box 20 that needs to be tested, thereby improving the arrangement and recovery speed of the temperature sensor. In addition, since the installation component 2 can be selectively detachably connected to one of the bracket component 1 and the inner wall 201 of the box 20, the installation component 2 with the temperature sensor fixed can be installed on the bracket component 1, or the installation component 2 with the temperature sensor fixed can be directly fixed on the inner wall 201 of the box 20, thereby improving the flexibility of the test bracket 10 in installing and fixing the temperature sensor.

[0049] Optionally, in this embodiment, if Figure 3As shown, the mounting assembly 2 with the temperature sensor fixed thereon can be directly magnetically fixed on the inner wall 201 of the box 20, thereby improving the arrangement and recovery speed of the temperature sensor in the box 20. Optionally, multiple mounting assemblies 2 can be provided, each mounting assembly 2 is fixed with a temperature sensor, and each mounting assembly 2 is magnetically attached to the inner wall 201 at a suitable position of the box 20, thereby better detecting the temperature at various positions in the box 20 and realizing the temperature uniformity test of the temperature field equipment.

[0050] It should be noted that, in a high temperature environment, the mounting assembly 2 is prone to demagnetization, which may easily lead to the inability of the mounting assembly 2 to be reliably magnetically attached to the inner wall 201 of the box 20. In order to solve the problem that the mounting assembly 2 cannot be reliably fixed at high temperatures, optionally, in this embodiment, when the temperature in the box 20 is lower than a preset temperature value (for example, lower than 80°C), the mounting assembly 2 with the temperature sensor fixed thereon may be directly magnetically attached to the inner wall 201 of the box 20; when the temperature in the box 20 is not lower than the preset temperature value, the mounting assembly 2 with the temperature sensor fixed thereon may be mounted on the bracket assembly 1, thereby fixing the mounting assembly 2 and the temperature sensor on the mounting assembly 2 in the box 20 through the bracket assembly 1. It should be noted that, in this embodiment, when the mounting assembly 2 and the temperature sensor on the mounting assembly 2 are fixed in the box 20 through the bracket assembly 1, the total weight of the entire test bracket 10 is no more than 350g, which is more lightweight and portable.

In this embodiment, by mounting the magnet member 22 on the mounting member 21, it is convenient to magnetically attract the mounting member 21 to the inner wall 201 of the box body 20 through the magnet member 22, thereby realizing the installation and fixing of the temperature sensor inside the box body 20.

The above arrangement enables, when the mounting assembly 2 fixed with the temperature sensor is mounted on the bracket assembly 1 for use, by adjusting the mounting position of the mounting assembly 2 on the connecting tube 12 and the bending posture of the connecting tube 12, the position of each temperature sensor inside the box 20 can be adjusted more flexibly and conveniently, ensuring that each temperature sensor is accurately adjusted to a suitable position in the box 20, and effectively improving the reliability of the temperature uniformity test of the temperature field equipment.

Optionally, in this embodiment, the temperature sensor can be an armored thermocouple, and the connecting pipe 12 can be an idle stainless steel pipe portion of an armored thermocouple with a diameter of φ3, which has the advantages of being resistant to high temperatures and easy to bend and shape, and also reduces resource waste.

[0055] Optionally, in this embodiment, if Figure 4 and Figure 6 As shown, the mounting assembly 2 also includes a fastener 23. When the mounting assembly 2 with the temperature sensor fixed thereon is mounted on the bracket assembly 1 for use, the magnet 22 is removed from the mounting member 21, and the mounting member 21 is sleeved on the connecting tube 12. After adjusting the position of the mounting member 21 on the connecting tube 12 along the axial direction of the connecting tube 12, the fastener 23 is screwed through the threaded mounting hole 2111 and abutted against the outer peripheral wall of the connecting tube 12, thereby achieving the installation and fixation of the mounting member 21 on the connecting tube 12. It should be noted that when it is necessary to remove the mounting member 21 from the connecting tube 12 or adjust the fixed position of the mounting member 21 on the connecting tube 12, the fastener 23 can be loosened. Specifically, in this embodiment, the fastener 23 can be a bolt.

[0056] Optionally, in this embodiment, if Figure 4 and Figure 6As shown, the mounting member 21 includes a connecting tube portion 211, a mounting portion 212 and a hanging portion 213, wherein the connecting tube portion 211 can be sleeved on the connecting tube 12, and a threaded mounting hole 2111 is provided on the outer peripheral wall of the connecting tube portion 211, the mounting portion 212 is arranged on the outer peripheral wall of the connecting tube portion 211, a temperature sensor is fixedly mounted on the mounting portion 212, and the hanging portion 213 is arranged on the outer peripheral wall of the connecting tube portion 211, and the hanging portion 213 is used to hang on the device in the box 20. The structural design of the above-mentioned mounting member 21 is not only convenient for sleeve-fixing the mounting member 21 on the connecting tube 12, but also for hanging the mounting member 21 on the device in the box 20 through the hanging portion 213, thereby improving the stability of the entire test bracket 10 installed and fixed in the box 20. It should be noted that, in this embodiment, the mounting member 21 may be an integrally formed member, or the mounting portion 212 and the hanging portion 213 may be separately welded to the outer peripheral wall of the connecting pipe portion 211 .

[0058] Optionally, in this embodiment, the fixing member 11 further includes a connecting bolt 113 , and the connecting bolt 113 can pass through the fixing cover 111 and be threadedly connected to the fixing base 112 , so that a detachable fastening between the fixing base 112 and the fixing cover 111 is achieved through the connecting bolt 113 .

[0059] Optionally, in this embodiment, a mounting ring 1111 is provided on one side of the fixing cover 111 away from the fixing base 112.

[0060] Optionally, in this embodiment, if Figure 5As shown, the slot 1121 is in a cross shape, and the slot 1121 passes through the outer peripheral surface of the fixed base 112. The above arrangement allows the connecting tube 12 installed in the slot 1121 to extend in four different directions, so that the entire test bracket 10 is in a cross shape, thereby meeting the installation requirements of temperature sensors in different positions. Optionally, in the present embodiment, the bracket assembly 1 includes two connecting tubes 12, each connecting tube 12 is L-shaped, so that the two connecting tubes 12 can make it easy for the bracket assembly 1 to have connecting tubes 12 extending outward in four different directions.
