Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a temperature sensor mounting structure for refrigerator testing. Background Technology

[0002] Currently, according to national or corporate requirements, temperature sensors need to be installed in various experiments on refrigerators. For details, please refer to Chinese patent application number CN202111108628.X, "A detection device and detection method for refrigerator process testing".

[0003] In existing technologies, when it is necessary to place the temperature sensor in the center of the refrigerator compartment and suspend it, aluminum foil tape or tin foil tape is often used to attach the temperature sensor wires to make the temperature sensor suspend.

[0004] The above-mentioned temperature sensor installation method has the following disadvantages: First, if the surface is rough, uneven, or has high moisture content during pasting, the tape may not adhere effectively to the installation position for a long time, causing the temperature sensor to deviate from its original standard position or even fall off, ultimately resulting in inaccurate experimental results; Second, if the temperature sensor is found to be installed incorrectly after placement, it is not easy to adjust and the tape must be removed and repositioned. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a temperature sensor mounting structure for refrigerator testing that has high installation stability and is easy to adjust the installation position, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is: a temperature sensor mounting structure for refrigerator testing, characterized in that it includes:

[0007] Suction cups are used to attach to the mounting wall of the refrigerator.

[0008] The telescopic assembly includes a fixed rod mounted on the suction cup and a movable rod telescopically mounted on the fixed rod; and

[0009] A temperature sensor is installed at the free end of the movable rod.

[0010] To ensure stable suction, the suction cup includes:

[0011] The suction cup body has two surfaces, which are referred to as the suction surface and the mounting surface, respectively.

[0012] A suction cup cover, which covers the mounting surface of the suction cup body and is connected to the periphery of the suction cup body; and

[0013] A pull rod, mounted on the suction cup cover, is used to drive the middle part of the suction cup body to move relative to the suction cup cover, so that the suction cup has at least two states:

[0014] In its initial state, the suction surface of the suction cup body is planar;

[0015] In the suction state, the suction surface of the suction cup body is concave, and a vacuum interlayer is formed between it and the mounting wall.

[0016] To facilitate the mounting and dismounting of the fixing rod on the suction cup, the surface of the suction cup cover is provided with a female connector, and the fixing end of the fixing rod has a male connector that can be inserted and connected with the female connector.

[0017] To facilitate the output of test results, the suction cup cover has a temperature output port, which is electrically connected to the female connector via a wire, and the temperature sensor is electrically connected to the male connector via a wire.

[0018] To avoid the need for an additional measuring ruler for distance testing, a telescopic ruler is also included, which can be telescopically mounted on the side of the suction cup.

[0019] To facilitate user guidance in measuring distances along the x and z axes, two telescopic rulers are provided. One ruler extends in the same direction as the length of the suction cup, while the other extends in the same direction as the width of the suction cup.

[0020] To facilitate efficient adjustment of the temperature sensor's mounting position on the y-axis, the extension and retraction direction of the movable rod is consistent with the height direction of the suction cup.

[0021] To avoid the need for additional measuring scales for distance testing, the sides of the fixed rod and the movable rod have scale markings spaced apart along their length.

[0022] To simplify the structure, the temperature sensor is a temperature-sensing copper column.

[0023] To ensure stable suction cup engagement, the mounting wall is a glass panel.

[0024] Compared with the prior art, the advantages of this utility model are as follows: the use of a suction cup in conjunction with a telescopic component to install the temperature sensor effectively prevents the temperature sensor from deviating from its original position or even falling off due to the loss of adhesiveness of the tape base due to changes in temperature and humidity inside the refrigerator, resulting in high installation stability; on the other hand, the suction cup facilitates the adjustment of the installation position of the temperature sensor on the x and z axes, and the telescopic component facilitates the adjustment of the installation position of the temperature sensor on the y axis. The combination of the two enables accurate installation of the temperature sensor in three-dimensional space. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings.

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0030] like Figures 1 to 3 The image shows a preferred embodiment of the temperature sensor mounting structure for refrigerator testing according to this utility model. This temperature sensor mounting structure is used to mount on the mounting wall 10 of the refrigerator and includes a suction cup 1, a telescopic assembly 2, a temperature sensor 3, and a telescopic ruler 4.

[0031] Among them, the mounting wall 10 is a glass panel.

[0032] The suction cup 1 is used to adhere to the mounting wall 10 and includes a suction cup body 11, a suction cup cover 12, and a pull rod 13. Specifically, the two sides of the suction cup body 11 are referred to as the suction surface and the mounting surface, respectively. The suction cup cover 12 is placed on the mounting surface of the suction cup body 11 and connected to the periphery of the suction cup body 11. The side of the suction cup cover 12 has a temperature output port 120, and the surface of the suction cup cover 12 is provided with a female connector 121. The temperature output port 120 is electrically connected to the female connector 121 through a wire (not shown in the figure). The pull rod 13 is mounted on the suction cup cover 12 and is used to drive the middle part of the suction cup body 11 to move relative to the suction cup cover 12, so that the suction cup 1 has at least two states: in the initial state, the suction surface of the suction cup body 11 is flat; in the suction state, the suction surface of the suction cup body 11 is concave and a vacuum interlayer 110 is formed between it and the mounting wall 10.

[0033] The telescopic assembly 2 includes a vertically arranged fixed rod 21 and a movable rod 22. Specifically, the fixed end of the fixed rod 21 has a male connector 211 that can be inserted and connected to the female connector 121 to facilitate the installation of the fixed rod 21 on the suction cup cover 12; the movable rod 22 is telescopically mounted on the fixed rod 21, and the telescopic direction of the movable rod 22 is consistent with the height direction of the suction cup cover 12. In addition, the sides of the fixed rod 21 and the movable rod 22 have scale markings 20 arranged at intervals along their length.

[0034] Temperature sensor 3 is a temperature-sensing copper column, installed at the free end of movable rod 22. Temperature sensor 3 is electrically connected to male connector 211 via a wire (not shown in the figure).

[0035] There are two telescopic rulers 4, each of which can be telescopically installed on the side of the suction cup cover 12. The telescopic direction of one telescopic ruler 4 is consistent with the length direction of the suction cup cover 12, and the telescopic direction of the other telescopic ruler 4 is consistent with the width direction of the suction cup cover 12.

[0036] The working principle of this embodiment is as follows: In use, in the initial state, the suction surface of the suction cup body 11 is flat. First, the suction position of the suction cup 1 on the mounting wall 10 is positioned according to the telescopic ruler 4, and the suction surface of the suction cup body 11 of the suction cup 1 is attached to the suction position of the mounting wall 10. Then, the pull rod 13 is pulled to drive the middle part of the suction cup body 11 towards the suction cup cover 12, so that the suction surface of the suction cup body 11 becomes concave and a vacuum interlayer 110 is formed between it and the mounting wall 10. At this time, as Figure 3 As shown, the suction cup 1 is in the suction state, and the pressure difference generated by the vacuum firmly and reliably adsorbs the entire temperature sensor mounting structure onto the mounting wall 10. Finally, the extension and retraction position of the movable rod 22 is adjusted to adjust the relative distance between the temperature sensor 3 and the mounting wall 10, thereby achieving accurate installation of the temperature sensor 3.

[0037] The advantages of the above scheme are:

[0038] (1) The temperature sensor is installed by using a suction cup 1 in conjunction with a telescopic component 2. On the one hand, this effectively prevents the temperature sensor from deviating from its original position or even falling off due to the loss of adhesiveness of the tape base due to changes in temperature and humidity inside the refrigerator, resulting in high installation stability. On the other hand, the suction cup 1 facilitates the adjustment of the installation position of the temperature sensor 3 on the x and z axes, and the telescopic component 2 facilitates the adjustment of the installation position of the temperature sensor 3 on the y axis. The combination of the two can achieve accurate installation of the temperature sensor 3 in three-dimensional space.

[0039] (2) A temperature sensor 3 is made of a temperature-sensing copper column, which has a simple structure;

[0040] (3) The setting of the scale mark 10 makes it convenient to instruct the user to measure the distance on the y-axis, and the setting of the two telescopic rulers 4 makes it convenient to instruct the user to measure the distance on the x and z axes, without having to hold a ruler to measure when using it.
