Description

Technical Field

[0001] The present application relates to the technical field of temperature point distribution testing, for example, to a point distribution device and a point distribution component for refrigerator temperature testing. Background Art

[0002] At present, when horizontal freezers are conducting power consumption, cooling, and condensation tests, it is necessary to arrange a temperature test device inside the box to test the temperature of preset points.

[0003] In the related art, tape is set at the cabinet opening of the refrigerator according to the position of the preset point, and then a temperature sensor is hung on the tape to measure the temperature of the preset point in the box to test the temperature of the preset point.

[0004] In the publicly available implementation process, it was found that the relevant technology has at least the following problems:

[0005] Although the related technology can test the temperature of the preset points in the refrigerator, the width of a large-capacity horizontal refrigerator is generally 0.45 meters to 0.65 meters. The tape measurement generally requires about 4 meters to 5 meters of tape, which causes waste of materials, cumbersome process, and wastes a lot of time. In addition, setting tape at the cabinet opening will affect the sealing performance between the door and the cabinet, and the deformation of the tape will also cause the position of the temperature test point to shift with the phase change of the tape, and the temperature accuracy of the preset point measured is low.

The telescopic rod 20 is arranged in the installation cavity. The opposite ends of the telescopic rod 20 are respectively connected to the cavity wall of the first accommodating cavity 1011 and the cavity wall of the second accommodating cavity 1021. The telescopic rod 20 can be telescoped to drive the first rod body 101 and / or the second rod body 102 to move relative to the telescopic rod 20.

[0041] The point distribution device for testing the temperature of a refrigerator provided by the embodiment of the present disclosure is provided with a telescopic rod 20 in the installation cavity of the support rod 10, so that the telescopic rod 20 can be extended and retracted to drive the first rod body 101 and / or the second rod body 102 connected to the opposite ends of the telescopic rod 20 to move relative to the telescopic rod 20.

When the point distribution device is set in the refrigerator cavity, the opposite ends of the point distribution device are respectively abutted against the opposite end walls of the cavity to measure the length between the opposite end walls, so as to set the temperature sensor at the preset point according to the measured length, and then measure the temperature value of the preset point. Reduce the waste of materials, reduce costs, reduce the cumbersomeness of the testing process, reduce time waste, and reduce the impact on the sealing performance between the door body and the box body of the refrigerator. Furthermore, the support rod 10 and the telescopic rod 20 can reduce the deformation of the point distribution device and improve the temperature accuracy of the preset points measured.

[0042] Specifically, the support rod 10 is a rod body made of a relatively hard material.

[0043] Optionally, the telescopic rod 20 includes: a first telescopic end connected to the cavity wall of the first accommodating cavity 1011 , and the movement of the first telescopic end drives the first rod body 101 to move relative to the telescopic rod 20 .

[0044] In this embodiment, by providing the first telescopic end, the first telescopic end can move relative to the other end of the telescopic rod 20 to achieve telescopic movement of the telescopic rod 20. The first rod body 101 is then driven to move relative to the telescopic rod 20 to change the length of the telescopic rod 20 exposed outside the installation cavity, thereby changing the distance between one end of the first rod body 101 and one end of the second rod body 102, and then changing the length between the two opposite ends of the support rod 10, that is, changing the length of the point distribution device.

[0045] Specifically, the other end of the telescopic rod 20 is fixedly connected to the cavity wall of the second accommodating cavity 1021 .

[0046] Optionally, the telescopic rod 20 includes: a second telescopic end connected to the cavity wall of the second accommodating cavity 1021 , and the movement of the second telescopic end drives the second rod body 102 to move relative to the telescopic rod 20 .

[0047] In this embodiment, by providing the second telescopic end, the second telescopic end can move relative to the other end of the telescopic rod 20 to achieve telescopic extension of the telescopic rod 20. Then the second rod body 102 is driven to move relative to the telescopic rod 20 to change the length of the telescopic rod 20 exposed outside the installation cavity, thereby changing the distance between one end of the first rod body 101 and one end of the second rod body 102, and then changing the length between the two opposite ends of the support rod 10, that is, changing the length of the point distribution device.

[0048] Specifically, the other end of the telescopic rod 20 is fixedly connected to the cavity wall of the first accommodating cavity 1011 .

[0049] Optionally, the telescopic rod 20 includes: a first telescopic end and a second telescopic end. The first telescopic end is connected to the cavity wall of the first accommodating cavity 1011, and the movement of the first telescopic end drives the first rod body 101 to move relative to the telescopic rod 20. The second telescopic end is connected to the cavity wall of the second accommodating cavity 1021, and the movement of the second telescopic end drives the second rod body 102 to move relative to the telescopic rod 20.

[0050] In this embodiment, by providing the first telescopic end and the second telescopic end, the first telescopic end and the second telescopic end can move relative to each other to achieve the telescopic rod 20. Then the first rod body 101 and the second rod body 102 are driven to move relative to the telescopic rod 20 to change the length of the telescopic rod 20 exposed outside the installation cavity, thereby changing the distance between one end of the first rod body 101 and one end of the second rod body 102, and then changing the length between the two opposite ends of the support rod 10, that is, changing the length of the point distribution device.

[0051] Optionally, combined Figure 1 As shown, the first rod body 101 can move relative to the center line 201 of the telescopic rod 20. That is, the connection between the first rod body 101 and the second rod body 102 is located at the center line 201 of the telescopic rod 20.

[0052] Specifically, the opening of the second accommodating cavity 1021 is fixed to the center line 201 of the telescopic rod 20, so that after the first rod body 101 moves relative to the center line 201 of the telescopic rod 20, the telescopic rod 20 is exposed outside the installation cavity. The length between the two opposite ends of the support rod 10 is changed, that is, the length of the point distribution device is changed.

[0053] Optionally, combined Figure 1 As shown, the second rod body 102 can move relative to the center line 201 of the telescopic rod 20. That is, the connection between the first rod body 101 and the second rod body 102 is located at the center line 201 of the telescopic rod 20.

[0054] Specifically, the opening of the first accommodating cavity 1011 is fixed to the center line 201 of the telescopic rod 20, so that after the second rod body 102 moves relative to the center line 201 of the telescopic rod 20, the telescopic rod 20 is exposed outside the installation cavity. The length between the two opposite ends of the support rod 10 is changed, that is, the length of the point distribution device is changed.

[0055] Optionally, combined Figure 1 As shown, the first rod body 101 can move relative to the center line 201 of the telescopic rod 20 , and the second rod body 102 can move relative to the center line 201 of the telescopic rod 20 .

[0056] Specifically, the first rod body 101 and the second rod body 102 can both move relative to the center line 201 of the telescopic rod 20, thereby increasing the upper limit of the length between the two opposite ends of the support rod 10, that is, increasing the upper limit of the length of the distribution device to adapt to a larger capacity refrigerator liner, thereby improving the practicality of the distribution device.

[0057] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, when the telescopic rod 20 has a first telescopic end, the telescopic rod 20 includes: a hard rod body 202 and a first spring 203. The first spring 203 can be telescopic. One end of the first spring 203 is connected to one end surface of the hard rod body 202, and the other end of the first spring 203 is configured as a first telescopic end.

[0058] In this embodiment, the hard rod body 202 and the first spring 203 are provided to realize the movement of the first telescopic end, and then realize the first telescopic end drives the first rod body 101 to move relative to the telescopic rod 20. By changing the length of the telescopic rod 20 exposed outside the installation cavity, the distance between one end of the first rod body 101 and one end of the second rod body 102 is changed, and then the length between the two opposite ends of the support rod 10 is changed, that is, the length of the point distribution device is changed.

[0059] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, in the case where the telescopic rod 20 has a second telescopic end, the telescopic rod 20 includes: a hard rod body 202 and a second spring 204. The second spring 204 can be telescopic. One end of the second spring 204 is connected to one end surface of the hard rod body 202, and the other end of the second spring 204 is configured as a second telescopic end.

[0060] In this embodiment, the hard rod body 202 and the second spring 204 are provided to realize the movement of the second telescopic end, and then realize the second telescopic end drives the second rod body 102 to move relative to the telescopic rod 20. By changing the length of the telescopic rod 20 exposed outside the installation cavity, the distance between one end of the first rod body 101 and one end of the second rod body 102 is changed, and then the length between the two opposite ends of the support rod 10 is changed, that is, the length of the point distribution device is changed.

[0061] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, in the case where the telescopic rod 20 has a first telescopic end and a second telescopic end, the telescopic rod 20 includes: a hard rod body 202, a first spring 203 and a second spring 204. The first spring 203 can be telescopic. One end of the first spring 203 is connected to one end surface of the hard rod body 202, and the other end of the first spring 203 is configured as a first telescopic end. The second spring 204 can be telescopic. One end of the second spring 204 is connected to the other end surface of the hard rod body 202, and the other end of the second spring 204 is configured as a second telescopic end.

[0062] In this embodiment, the first telescopic end and the second telescopic end are moved relative to each other by providing a hard rod body 202, a first rod body 101 and a second spring 204. The first rod body 101 and the second rod body 102 are driven to move relative to the telescopic rod 20 to change the length of the telescopic rod 20 exposed outside the installation cavity. The distance between one end of the first rod body 101 and one end of the second rod body 102 is changed, and the length between the two opposite ends of the support rod 10 is changed, that is, the length of the point distribution device is changed.

[0063] Optionally, the compression ratio of the spring is a preset compression ratio. The spring includes a first spring 203 and / or a second spring 204 .

[0064] In this embodiment, the compression ratio of the spring is set to achieve the setting of the compression length of the spring.

[0065] Specifically, taking the first spring 203 and the first rod 101 as an example, the minimum compressed length of the spring is m, the length of the space formed between the first accommodating cavity 1011 and one end of the telescopic rod 20 is L, and L≥m. The length relationship between the second spring 204 and the second rod 102 is the same, and will not be repeated here.

[0066] Optionally, during the movement of the first rod body 101 relative to the telescopic rod 20 , the first spring 203 is always located in the space formed by the first accommodating cavity 1011 and one end surface of the hard rod body 202 .

[0067] In this embodiment, the first spring 203 is restricted to always be located in the space formed by the first accommodating cavity 1011 and the end surface of one end of the telescopic rod 20, so as to ensure that the hard rod body 202 structure of the support rod 10 and the telescopic rod 20 is always connected, so as to reduce the exposure of the spring outside the space formed by the first accommodating cavity 1011 and the end surface of one end of the telescopic rod 20, and the problem of the point distribution device breaking due to the poor hardness of the spring. In addition, the deformation of the point distribution device is reduced, and the temperature accuracy of the preset point is improved.

[0068] Optionally, during the movement of the second rod body 102 relative to the telescopic rod 20 , the second spring 204 is always located in the space formed by the second accommodating cavity 1021 and one end surface of the hard rod body 202 .

[0069] In this embodiment, the second spring 204 is restricted to always be located in the space formed by the second accommodating cavity 1021 and the end surface of one end of the telescopic rod 20, so as to ensure that the hard rod body 202 structure of the support rod 10 and the telescopic rod 20 is always connected, so as to reduce the spring being exposed outside the space formed by the second accommodating cavity 1021 and the end surface of one end of the telescopic rod 20, and the problem of the point distribution device breaking due to the poor hardness of the spring. In addition, the deformation of the point distribution device is reduced, and the temperature accuracy of the preset point position is improved.

[0070] Optionally, when the first rod body 101 moves relative to the telescopic rod 20, the first spring 203 is always located in the space formed by the first accommodating cavity 1011 and one end surface of the hard rod body 202. When the second rod body 102 moves relative to the telescopic rod 20, the second spring 204 is always located in the space formed by the second accommodating cavity 1021 and one end surface of the hard rod body 202.

[0071] Optionally, combined Figure 2 , Figure 5 and Figure 6 As shown, sealing sheets 205 are respectively provided at both ends of the hard rod body 202, and the diameter of the sealing sheet 205 is larger than the outer diameter of the hard rod body 202. The sealing sheet 205 is used to form a space with the cavity wall of the first accommodating cavity 1011 and / or the cavity wall of the second accommodating cavity 1021. The first spring 203 is always located in the space formed by the sealing sheet 205 and the cavity wall of the first accommodating cavity 1011. The second spring 204 is always located in the space formed by the sealing sheet 205 and the cavity wall of the second accommodating cavity 1021.

[0072] It is understandable that the telescopic rod 20 can be automatically extended and retracted by using a spring as in the above embodiment, or the telescopic rod 20 can be manually pulled to extend and retract as in the following embodiment.

[0073] Optionally, the telescopic rod 20 includes: a first tube body and a second tube body. The first tube body is provided with a telescopic space running through the length direction of the first tube body. The second tube body is arranged in the telescopic space, and the second tube body can slide and telescope relative to the first tube body.

[0074] Specifically, the diameter of the first end of the second tube body is A, and the diameter of the second end of the second tube body is B. The diameter of the first end of the first tube body is C, and the diameter of the second end of the first tube body is D. <B<C<D。

[0075] Specifically, a slot is provided at the second end of the second tube body. A clamping protrusion is provided on the side wall of the telescopic space, and the clamping protrusion is located at the first end of the first tube body. The clamping protrusion is clamped with the slot to prevent the second tube body from sliding out of the telescopic space.

[0076] Optionally, the outer side walls of the support rod 10 and the telescopic rod 20 are marked with scales, with millimeters as the unit.

[0077] In this embodiment, scales are marked on the outside of the support rod 10 and the telescopic rod 20, so that the scales on the point placement device can be directly viewed, and then the temperature sensor is set at the scale value corresponding to the preset point. The tedious process of measuring the scale with a ruler is reduced, and time waste is reduced. In addition, the problem of inaccurate preset points caused by recalculating the scales multiple times is reduced.

[0078] For example, commonly used lengths can be marked on the support rod 10 and telescopic rod 20 of the point distribution device according to commonly used positions to reduce the time wasted by having to recheck the scale each time.

[0079] Optionally, the support rod 10 further includes a fixing member 103, which is respectively disposed at one end of the first rod body 101 and the second rod body 102. The opening of the first accommodating cavity 1011 and the fixing member 103 are respectively located at two opposite end surfaces of the first rod body 101. The opening of the second accommodating cavity 1021 and the fixing member 103 are respectively located at two opposite end surfaces of the second rod body 102.

[0080] In this embodiment, by providing a fixing member 103, the fixing member 103 and the cavity wall of the refrigerator are abutted against each other to achieve fixation between the distribution device and the cavity wall of the refrigerator, thereby reducing the impact on the sealing performance between the door and the box body of the refrigerator.

[0081] Optionally, combined Figures 1 to 4As shown, the fixing member 103 includes: a first fixing plate 1031 and a second fixing plate 1032. The first fixing plate 1031 is arranged on one end surface of the first rod body 101. The second fixing plate 1032 is arranged on one end surface of the second rod body 102. Wherein, when the point distribution device is arranged in the cold cabinet cavity, the first fixing plate 1031 and the second fixing plate 1032 are respectively in contact with two opposite cavity walls of the cold cabinet cavity.

[0082] In this embodiment, the first fixing piece 1031 and the second fixing piece 1032 are provided to achieve the contact between the point distribution device and the two opposite walls of the cold cabinet cavity, thereby achieving the use of the point distribution device to determine the preset point position in the cold cabinet cavity, so as to facilitate the installation of a temperature sensor at the preset point position to achieve the detection of the preset point temperature.
