[0030] The third positioning member is connected to a first end of the second connecting rope, and the fourth positioning member is connected to a second end of the second connecting rope.

[0031] In this way, the starting point and the ending point of the other diagonal line of the measured member can be determined. In this way, the directionality of the measurement can be ensured, and the error caused by the deviation of the connecting rope from the direction of the diagonal line can be reduced.

[0032] In some embodiments of the present application, the fixing device comprises a first rotating disc and a second rotating disc, the first rotating disc and the second rotating disc being rotatably arranged on the mounting bracket.

[0075] As the background, in order to ensure the quality and consistency of the refrigerator, the diagonal length of the refrigerator body and door body needs to be measured, and the difference between the two diagonal lines is required to be within a certain range (such as within 2mm). This step can be used to improve the unevenness of the body and the door body.

[0076] In actual operation, due to the large size of the diagonal line of the body and the door body, two people usually cooperate to operate. One person fixes one end of the ruler, and the other person straightens the ruler and reads the size of the other end. Such a measurement method increases the labor cost of measurement work.

[0077] Therefore, the diagonal line measuring tool of the embodiment of the present application can determine the starting point and ending point of the diagonal line by fixing the first positioning member and the second positioning member with the measured member. The measurement direction of the diagonal line is determined by connecting the first positioning member and the second positioning member with the connecting rope. The measurement direction of the laser ranging assembly is parallel to the extension direction of the connecting rope by adjusting the laser ranging assembly. The laser ranging assembly emits signals to both sides, which are reflected by the first positioning member and the second positioning member, so that the laser ranging assembly can obtain the distance between the first positioning member and the second positioning member. By using the diagonal line measuring tool, one person can complete the measurement of the diagonal line length, thereby reducing the labor cost.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0084] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0085] Reference Figure 1As shown, the embodiment of the present application provides a diagonal line measuring tool 1, which can be used to measure the diagonal line length of a measured object. For example, the diagonal line measuring tool 1 can be used to measure the diagonal line length of the top of a refrigerator. The height of the refrigerator body is usually high, which increases the difficulty of measuring the diagonal line length of the top of the refrigerator body. Through the diagonal line measuring tool 1, the difficulty of measuring the diagonal line length of the top of the refrigerator body can be reduced.

[0086] The diagonal line measuring tool 1 can include a fixing device 10. The fixing device 10 can ensure that there is no relative displacement with the measured object during the measurement process, so as to avoid the deviation of the measurement result caused by the movement of the fixing device 10.

[0087] The fixing device 10 can include a mounting bracket 110. The mounting bracket 110 can be mounted on the measurement surface of the measured object, so as to ensure that the diagonal line measuring tool 1 will not be displaced during the measurement process.

[0088] Referring to Figure 2 As shown, in some embodiments, the mounting bracket 110 is provided with a mounting disc 111 and a supporting shaft 112, and the mounting disc 111 is arranged at both ends of the supporting shaft 112. The mounting disc 111 located at one end of the supporting shaft 112 can be mounted on the measurement surface of the measured object, and the mounting disc 111 located at the other end of the supporting shaft 112 can be used to mount other parts, so as to improve the integration of the fixing device 10.

[0089] For example, the bottom of the mounting bracket 110 can be provided with a suction cup. The mounting bracket 110 is adsorbed on the measured object through the suction cup, which facilitates the disassembly of the mounting bracket 110 and reduces the installation time of the diagonal line measuring tool 1.

[0090] The fixing device 10 can include a positioning assembly 120. The positioning assembly 120 can mark two endpoints of the diagonal line of the measured object, so as to ensure the accuracy of the measurement of the diagonal line measuring tool 1.

[0091] In combination with Figure 1 Referring to Figure 3 As shown, the positioning assembly 120 can include a first positioning member 121. The first positioning member 121 is used to be fixed with the measured object, and the first positioning member 121 is located at the first end of the diagonal line of the measured object. In this way, the starting point of the diagonal line measurement can be ensured, and the starting point deviation that may occur during the measurement process is reduced.

[0092] For example, the first positioning member 121 can be provided as an angular coupling plate. The angular coupling plate is provided with a limiting portion 126. The angular coupling plate can be fitted with the corner of the measured object, and the displacement of the angular coupling plate can be limited. Through the structure of the angular coupling plate, the position of the angular coupling plate when being fitted is limited, so that the angular coupling plate is more stable when being fitted with the measured object.

[0093] The positioning assembly 120 can include a second positioning member 122. The second positioning member 122 is used to fix the to-be-measured member, and the second positioning member 122 is located at a second end of the diagonal line of the to-be-measured member. In this way, the end point of the diagonal line can be determined, and the end point deviation that may occur in the measurement process is reduced.

[0094] For example, the second positioning member 122 can be provided as an angle joint plate. The angle joint plate is provided with a limiting portion 126. The angle joint plate can be attached to the corner of the to-be-measured member, and the displacement of the angle joint plate can be limited. By limiting the position of the angle joint plate when the angle joint plate is attached, the angle joint plate can be more stable when the angle joint plate is attached to the to-be-measured member.

[0095] In combination Figure 2 Referring to Figure 4 As shown in the figure, the fixing device 10 can include a connecting rope 130. The connecting rope 130 is arranged in the first direction in the mounting bracket 110. The first direction is parallel to the measurement surface. The first end of the connecting rope 130 is connected to the first positioning member 121, and the second end of the connecting rope 130 is connected to the second positioning member 122. By arranging the connecting rope 130 parallel to the diagonal line of the to-be-measured member, the directionality of the measurement can be ensured, and the error caused by the deviation of the connecting rope 130 from the direction of the diagonal line is reduced.

[0096] The diagonal line measurement tool 1 can include a laser ranging assembly 20. The laser ranging assembly 20 is movably arranged in the mounting bracket 110. By adjusting the laser ranging assembly 20, the laser ranging assembly 20 can be fixed with the connecting rope 130, so that the measurement direction of the laser ranging assembly 20 is parallel to the extension direction of the connecting rope 130.

[0097] The laser ranging assembly 20 can emit signals to both sides, and the signals propagate in the parallel direction of the extension direction of the connecting rope 130 until reaching the first positioning member 121 and the second positioning member 122. The first positioning member 121 and the second positioning member 122 reflect the signals to the laser ranging assembly 20, so that the laser ranging assembly 20 can obtain the distance between the first positioning member 121 and the second positioning member 122.

[0098] The measurement method of the diagonal line measurement tool 1 is as follows: first, the diagonal line measurement tool 1 can fix the first positioning member 121 at the first end of the diagonal line of the to-be-measured member, and fix the second positioning member 122 at the second end of the diagonal line of the to-be-measured member, so as to determine the start point and the end point of the diagonal line.

[0099] Then, the connecting rope 130 can be arranged in the mounting bracket 110, the first end of the connecting rope 130 can be connected to the first positioning member 121, and the second end of the connecting rope 130 can be connected to the second positioning member 122. After the connecting rope 130 is straightened, the mounting bracket 110 is fixed on the measurement surface, so that the extension direction of the connecting rope 130 is parallel to the direction of the diagonal line.

[0100] Then, the measuring direction of the laser ranging assembly 20 can be adjusted to be parallel to the extension direction of the connecting rope 130.

[0101] Finally, the laser ranging assembly 20 can emit signals to both sides, and the signals propagate along the parallel direction of the extension of the connecting rope 130 until reaching the first positioning member 121 and the second positioning member 122, which reflect the signals to the laser ranging assembly 20, so that the laser ranging assembly 20 can obtain the distance between the first positioning member 121 and the second positioning member 122.

[0102] The first positioning member 121 and the second positioning member 122 are fixed with the measured member to determine the start point and the end point of the diagonal line. The connecting rope 130 is connected with the first positioning member 121 and the second positioning member 122 to determine the measuring direction of the diagonal line. The laser ranging assembly 20 is adjusted so that the measuring direction of the laser ranging assembly 20 is parallel to the extension direction of the connecting rope 130. The laser ranging assembly 20 emits signals to both sides, and the signals are reflected by the first positioning member 121 and the second positioning member 122, so that the laser ranging assembly 20 can obtain the distance between the first positioning member 121 and the second positioning member 122. By using the diagonal line measuring tool 1, one person can complete the measurement of the diagonal line length, thereby reducing the labor cost. The laser ranging assembly 20 can quickly obtain the numerical value of the diagonal line length, thereby improving the efficiency of the measurement of the diagonal line length.

[0103] Referring to Figure 5 As shown, the laser ranging assembly 20 can include a laser range finder 210. The laser range finder 210 can emit a laser pulse signal, and the length of the diagonal line can be determined by measuring the time from emission to reception of the laser pulse signal.

[0104] The laser range finder 210 can have high precision and stability, which can improve the precision of the diagonal line measurement. The use of the laser range finder 210 can eliminate the subjectivity and errors of human reading data, thereby improving the measurement precision of the diagonal line length.

[0105] The laser range finder 210 can be rotatably arranged on the mounting bracket 110, so that the emission direction of the laser range finder 210 can be adjusted. The direction of the laser range finder 210 emitting the laser pulse signal is adjusted to be parallel to the extension direction of the connecting rope 130, thereby ensuring that the emission direction of the laser range finder 210 is the same as the measuring direction of the diagonal line.

[0106] In some embodiments, the laser ranging assembly 20 can include a ranging instrument mounting seat 230, and the laser ranging instrument 210 is mounted on the ranging instrument mounting seat 230. The ranging instrument mounting seat 230 can be rotatably arranged on the mounting bracket 110. By rotating the ranging instrument mounting seat 230 relative to the mounting bracket 110, the laser ranging instrument 210 is driven to rotate, so that the rotation of the laser ranging instrument 210 is more stable.

[0107] In addition, by mounting the laser ranging instrument 210 on the ranging instrument mounting seat 230, the laser ranging instrument 210 can be removed from the ranging instrument mounting seat 230, which facilitates the maintenance and replacement of the laser ranging instrument 210.

[0108] Referring to Figure 6 As shown in the figure, the laser ranging assembly 20 can include a guide bracket 220. The guide bracket 220 is connected with the laser ranging instrument 210. The laser ranging instrument 210 can rotate, and the guide bracket 220 can rotate with the laser ranging instrument 210 to the extension direction of the connecting rope 130. The guide bracket 220 is fixed with the connecting rope 130, so as to determine the measurement direction of the laser ranging instrument 210. In this way, the measurement direction of the laser ranging instrument 210 can be limited, so as to ensure the accuracy of the measurement result.

[0109] The guide bracket 220 can include an extension piece 221. The extension piece 221 can be arranged on the ranging instrument mounting seat 230. The ranging instrument mounting seat 230 can mount multiple components, so as to improve the integration of the diagonal line measurement tool 1.

[0110] The extension direction of the extension piece 221 is parallel to the measurement surface, so as to ensure that the guide bracket 220 can be connected with the connecting rope 130, so that the laser ranging instrument 210 can keep the measurement direction during the measurement process, thereby improving the accuracy of the diagonal line length measurement.

[0111] In some embodiments, the extension piece 221 can be telescopic. When the diagonal line measurement tool 1 is not used, the extension piece 221 can be shortened in length. The extension piece 221 reduces the space occupation, so as to facilitate the carrying and storage of the diagonal line measurement tool 1.

[0112] The guide bracket 220 can include a movable piece 222. The movable piece 222 can be arranged on the extension piece 221. The extension piece 221 can be driven to rotate with the laser ranging instrument 210, and the movable piece 222 is connected with the connecting rope 130 through the end of the movable piece 222 away from the extension piece 221. In this way, the measurement direction of the laser ranging instrument 210 can be limited, so as to ensure the accuracy of the diagonal line length measurement result.

[0113] For example, the movable piece 222 can be made of a transparent material. In this way, the movable piece 222 can not hinder the signal propagation when the laser range finder 210 emits the signal, so that the signal received by the laser range finder 210 is relatively weak, and the accuracy of the diagonal length measurement is affected.

[0114] In some embodiments, two movable pieces 222 can be arranged on both sides of the extension piece 221. The two movable pieces 222 are respectively connected to different positions of the connecting rope 130, so that the connection between the guide bracket 220 and the connecting rope 130 is more stable, and the measurement direction of the laser range finder 210 can be kept during the measurement, so that the accuracy of the measurement is improved.

[0115] Referring to Figure 7 As shown in the figure, the movable piece 222 can be provided with a plug-in interface 2221, and the opening direction of the plug-in interface 2221 is outward. The movable piece 222 can be plugged with the connecting rope 130 through the plug-in interface 2221, so as to limit the direction of the guide bracket 220. In this way, the installation and disassembly between the guide bracket 220 and the connecting rope 130 are facilitated.

[0116] Referring to Figure 8 As shown in the figure, in some embodiments, the extension piece 221 can rotate around its own extension direction, and the extension piece 221 can be fixed with the movable piece 222. The extension piece 221 can be rotated by rotating the laser range finder 210 to drive the guide bracket 220, and the extension piece 221 can drive the movable piece 222 to move, so that the movable piece 222 can be moved to the position connected with the connecting rope 130 more intuitively. In this way, the rotation angle of the laser range finder 210 does not need to be adjusted, and the measurement time of the diagonal length is saved.

[0117] In other embodiments, the movable piece 222 can rotate around the extension direction of the extension piece 221, and the extension piece 221 can be fixed with the laser range finder 210. By rotating the movable piece 222, the extension direction of the movable piece 222 can be adjusted to a direction parallel to the measurement plane, so as to facilitate the storage of the diagonal measurement tool 1. In addition, by rotating the movable piece 222, the movable piece 222 can be prevented from colliding with or interfering with the part of the measured piece when the diagonal measurement tool 1 measures the diagonal length, so that the adaptability and flexibility of the diagonal measurement tool 1 are improved.

[0118] Referring to Figure 9 As shown in the figure, the connecting rope 130 can include a first connecting rope 131 and a second connecting rope 132. The first connecting rope 131 and the second connecting rope 132 can satisfy the simultaneous measurement of two diagonal lengths.

[0119] The positioning assembly 120 includes a first positioning assembly and a second positioning assembly. The first positioning assembly is connected to both ends of the first connecting rope 131, and the second positioning assembly is connected to both ends of the second connecting rope 132. The first positioning assembly can be connected to the first end and the second end of the diagonal of the workpiece under test. The second positioning assembly can be connected to the first end and the second end of the other diagonal of the workpiece under test. This configuration allows for the measurement of the lengths of both diagonals, thereby improving the measurement efficiency of the diagonal measuring fixture 1.

[0120] The second positioning component may include a third positioning element 123. The third positioning element 123 can be used to fix the part under test, and the third positioning element 123 can be located at the first end of the other diagonal of the part under test. This allows the other diagonal of the part under test to have a clear starting point, reducing the possible starting point offset during the measurement process.

[0121] The second positioning component may include a fourth positioning element 124. The fourth positioning element 124 can be used to fix the test piece, and the fourth positioning element 124 can be located at the second end of the other diagonal of the test piece. This allows the other diagonal of the test piece to have a clear end point, reducing the possibility of endpoint offset during measurement.

[0122] Combination Figure 4 and Figure 9 As shown, the starting and ending points of the other diagonal of the part under test are determined by connecting the third positioning element 123 to the first end of the second connecting rope 132 and the fourth positioning element 124 to the second end of the second connecting rope 132. This ensures the directionality of the measurement and reduces errors caused by the connecting rope 130 deviating from the diagonal direction.

[0123] Reference Figure 10 As shown, the fixing device 10 includes a first turntable 140. The first turntable 140 is provided with a through first adjustment hole 141 in the radial direction. A first connecting rope 131 passes through the first adjustment hole 141. The first turntable 140 rotates through the first adjustment hole 141 to adjust the direction of the first connecting rope 131.

[0124] For example, the first turntable 140 and the support shaft 112 can be installed with an interference fit. After the first turntable 140 rotates, it will not rotate back under the tension of the first connecting rope 131, thus maintaining the position of the first turntable 140 and ensuring the stability of the measurement direction.

[0125] For diagonals of different sizes of the measured piece, the directions of the diagonals are different. In order to ensure the direction of the first connecting rope 131 from the mounting bracket 110 to the first positioning piece 121, the extension direction of the first adjusting hole 141 is adjusted to be parallel to the connecting line of the first positioning piece 121 and the second positioning piece 122 by rotating the first rotating disc 140. In this way, the measurement direction of the diagonal line measurement tool 1 can be ensured, and the accuracy of the measurement result can be ensured.

[0126] The fixing device 10 comprises a second rotating disc 150. The second rotating disc 150 is provided with a through second adjusting hole 151 in the radial direction, and the second connecting rope 132 is arranged through the second adjusting hole 151. The second rotating disc 150 is rotated to adjust the direction of the second connecting rope 132 through the second adjusting hole 151.

[0127] For diagonals of different sizes of the measured piece, the directions of the diagonals are different. In order to ensure the direction of the second connecting rope 132 from the mounting bracket 110 to the second positioning piece 122, the extension direction of the second adjusting hole 151 is adjusted to be parallel to the connecting line of the third positioning piece 123 and the fourth positioning piece 124 by rotating the second rotating disc 150. In this way, the measurement direction of the diagonal line measurement tool 1 can be ensured, and the accuracy of the measurement result can be ensured.

[0128] Referring to Figure 11 As shown, the positioning assembly 120 and the plane where the measured piece is fixed are provided with at least one magnetic piece 125. That is, the first positioning piece 121, the second positioning piece 122, the third positioning piece 123 and the fourth positioning piece 124 and the plane where the measured piece is fixed can be provided with one or more magnetic pieces 125. The positioning assembly 120 is fixed to the measured piece by being adsorbed to the measured piece through the magnetic piece 125. In this way, the deviation of the positioning assembly 120 can be prevented, and the deviation of the starting and ending points of the diagonal line can be prevented, so that the deviation of the measurement result can be prevented.

[0129] In addition, by arranging the magnetic piece 125, the installation of each positioning piece can be facilitated, and the measurement efficiency of the diagonal line measurement tool 1 can be improved.

[0130] For example, the magnetic piece 125 can be a permanent magnet. The magnetic field strength of the permanent magnet is large, and the stability of the fixing of each positioning piece to the measured piece can be improved.

[0131] The side of the mounting bracket 110 facing the laser range finder 210 can be provided with a display, so that the measurement result can be observed from the display. The display can be electrically connected with the laser range finder 210, and the display can display the measurement data of the diagonal line length of the laser range finder 210.

[0132] The display can display the lengths of two diagonals of the measured piece. In this way, the measurement result of the diagonal line length can be more intuitive.

[0133] In some embodiments, the display can calculate and display the difference between the two diagonal lines. The diagonal line measuring tool 1 can be set with a preset value. When the difference is greater than the preset value, the screen of the display can be set to red to prompt that the difference between the two diagonal lines is too large, which can affect the quality of the refrigerator. For example, when the difference between the two diagonal lines is greater than 2 mm, the display will automatically display red to prompt that the difference between the two diagonal lines exceeds the preset value.
