Description

Technical Field

[0001] The present invention relates to the technical field of conical thin-wall dimension measurement, and particularly to a measuring fixture and method for a decorative ring of a drum washing machine. Background Art

[0002] A drum washing machine is one of the household appliances that can be opened from the front side; as a large household appliance, the washing machine needs to occupy a large space after installation. With its front-opening design, a horizontal board can be set above the drum washing machine to increase the utilization rate of the space above the drum washing machine. Compared with a pulsator washing machine, it has better space utilization. Due to the front-opening design of the drum washing machine, compared with a pulsator washing machine, a better sealing and waterproof effect is required between the washing machine door and the washing machine main body.

[0003] Existing drum washing machines generally include a washing machine main body, a drum, and a door body. A clothing inlet is provided on the front side of the washing machine main body. The drum is rotatably arranged inside the washing machine door body. The drum is used to hold the clothes to be washed and drive the clothes to be washed to rotate for cleaning. The door body is arranged on the front side of the washing machine main body, and the door body plays a role in preventing the clothes from rolling out of the drum. Since a good sealing effect needs to be ensured after the door body and the washing machine main body are closed during the process of washing clothes, the door body is usually set in a conical shape, and the size of the door body gradually decreases from the outside to the inside. The conical structure can better ensure that after the door body is closed, there is a good sealing effect between the door body and the washing machine main body.

[0004] In the prior art, a conical decorative ring is usually arranged between the washing machine main body and the door body. A component for fixing the decorative ring to the washing machine main body is provided on the outer side wall of the decorative ring, and a through hole for hinging the door body and the washing machine main body is also provided on the side wall of the decorative ring. The through hole is usually located at the larger end of the decorative ring, and the inner wall of the decorative ring is relatively smooth, so that the door body can abut against the inner wall of the decorative ring, and it is convenient for the inner side of the door body to press against the inner wall of the decorative ring and extend into the washing machine main body. The smaller end has a good fitting effect with the door body, which has a good auxiliary effect on improving the sealing and waterproof effect of the door body. To meet the foregoing basic requirements, it is necessary to ensure that the size of the designed decorative ring matches the size required for the clothing inlet on the front side of the washing machine main body to improve the assembly efficiency and sealing and waterproof effect of the drum washing machine. Therefore, it is necessary to measure the size of the decorative ring during installation, especially the inner diameter of the smaller end of the decorative ring, which is an important dimension when installing the decorative ring.

[0005] Since the decorative ring is a conical thin-wall structure and the decorative ring cannot maintain its circumferential state well and deforms without support, it is easy to have a large error due to deformation during the direct measurement of the size of the decorative ring, resulting in a large error in the size measurement of the decorative ring, and further affecting the subsequent installation efficiency of the decorative ring. Summary of the Invention

[0006] The object to be achieved by the present invention is to provide a measuring jig and method for a decorative ring of a drum washing machine, to solve the problem of large dimensional errors occurring during the measurement of the decorative ring due to its thin-walled structure, improve the stability of the thin-walled decorative ring during the measurement process, avoid deformation of the decorative ring during the measurement process and generate large measurement errors, and improve the overall installation efficiency of the decorative ring.

[0007] To achieve the above object, the present invention adopts the following technical solution: A measuring jig for a decorative ring of a drum washing machine includes a measuring workbench for placing the decorative ring and a locking member. The outer peripheral wall of the measuring workbench is tapered and has the same taper as the inner wall of the decorative ring. The decorative ring has a connecting portion for installation. The locking member is arranged on the measuring workbench and has a locked state and an unlocked state. When the locking member is in the locked state, it presses against the connecting portion to stabilize the decorative ring. When the locking member is in the unlocked state, it is convenient to place or remove the decorative ring. On the end face of the smaller end of the measuring workbench, there are centrally symmetric first positioning structures and second positioning structures, and the first positioning structures and the second positioning structures provide a positioning reference for the measuring tool when measuring the inner diameter of the smaller end of the decorative ring.

[0008] After adopting the above technical scheme, the present invention has the following advantages: when testing the size of the smaller end of the decorative ring, the decorative ring is placed on a measuring workbench with the same taper as the inner wall of the decorative ring, so that the outer peripheral wall of the measuring workbench is supported on the inner wall of the decorative ring, and the decorative ring is supported during the measurement process to avoid deformation of the decorative ring during the size measurement process, thereby ensuring the accuracy of the measurement and reducing the error in the measurement process; after the decorative ring is placed on the measuring workbench, the decoration is locked or unlocked by a locking piece; specifically, before measurement, the locking piece is adjusted to a locked state so that the locking piece is pressed down on the connecting part of the decorative ring, thereby improving the stability of the decorative ring on the measuring workbench and reducing the possibility that the decorative ring moves upward during the measurement process and affects the accuracy of the measurement; when the measured decorative ring needs to be removed from the measuring workbench, the locking piece is switched to an unlocked state, so that the decorative ring can be easily removed; when measuring the inner diameter of the smaller end of the decorative ring, a first positioning structure and a second positioning structure that are centrally symmetrically arranged on the end surface of the smaller end of the measuring workbench are used to provide a positioning reference for the measuring tool when measuring the inner diameter of the smaller end of the decorative ring, so that the measuring tool measures a dimension that is closer to the diameter direction of the measuring workbench, ensuring that the measured dimension data is closer to the actual dimension of the decorative ring, further reducing the measurement error. In addition, the first positioning structure and the second positioning structure position the measuring tool to reduce the deviation of the measuring tool due to lack of assistance during the measurement process; the decorative ring is supported by the measuring workbench as a whole, and the locking member is used to stabilize the decorative ring, thereby improving the stability of the decorative ring during the measurement process, reducing the error of the decorative ring during the measurement process, and avoiding deformation of the decorative ring during the measurement process, thereby improving the accuracy of the measured dimension.

[0009] Furthermore, there are multiple groups of the first and second positioning structures that are centrally symmetrical distributed along the circumferential direction of the measuring workbench, and the measuring tool obtains multiple data of the inner diameter of the smaller end of the decorative ring through the multiple groups of the first and second positioning structures that are centrally symmetrical.

[0010] By adopting the above-mentioned technical solution, multiple groups of first positioning structures and second positioning structures are set, and multiple groups of data of the inner diameter of the smaller end of the decorative ring are measured through the multiple groups of first positioning structures and second positioning structures. The average value is then calculated through the multiple groups of data, so as to further reduce the measurement error of the inner diameter of the smaller end of the decorative ring and improve the accuracy of the measured dimensional data.

[0011] Furthermore, the locking piece is on the end surface of the smaller end of the measuring workbench and avoids the first positioning structure and the second positioning structure to avoid the measuring tool.

[0012] By adopting the above technical solution, the locking member avoids the first positioning structure and the second positioning structure, thereby preventing the locking member from affecting the measuring tool, and further ensuring the accuracy of the inner diameter measurement of the smaller end of the decorative ring.

[0013] Further, the locking member includes a cantilever beam and a pressing rod. One end of the cantilever beam is hinged to the measuring workbench, and the other end is a free end. In the locked state, the free end extends to the outside of the decorative ring and the pressing rod presses against the connecting portion of the decorative ring. In the unlocked state, the free end is located inside the outer wall of the smaller end of the measuring workbench to avoid the decorative ring.

[0014] With the foregoing technical solution, when setting the locking member, the locking member is set in the form of a cantilever beam and a pressing rod. Through the hinge connection between the cantilever beam and the measuring workbench, it is convenient to switch between the locked state and the unlocked state of the locking member, improving the convenience of installing and removing the decorative ring; the pressing rod switches states as the cantilever beam rotates. In the locked state, the cantilever beam drives the pressing rod to press against the connecting portion of the decorative ring, thereby pressing to stabilize the decorative ring. In the unlocked state, the free end of the cantilever beam drives the pressing rod to rotate towards the inner wall of the measuring workbench until the free end is located inside the outer wall of the smaller end of the measuring workbench, thereby avoiding the decorative ring during the placement and removal of the decorative ring and preventing the decorative ring from being worn and damaged by the free end during the placement and removal process.

[0015] Further, a strip-shaped hole is provided at the free end, and the pressing rod is inserted through the strip-shaped hole. The pressing rod adjusts its position in the strip-shaped hole through an adjusting member.

[0016] With the foregoing technical solution, a strip-shaped hole is provided at the free end of the cantilever beam, and the pressing rod is arranged in the strip-shaped hole. The position of the pressing rod in the strip-shaped hole is adjusted through the adjusting member, and then the position of the pressing rod in the radial direction of the measuring workbench is adjusted to ensure that the pressing rod can press against the connecting portion, thereby ensuring that the locking member can accurately lock the decorative ring and ensuring the stability of the decorative ring during the measurement process.

[0017] Further, the adjusting member includes a first adjusting portion and a second adjusting portion respectively arranged on both sides of the free end along the length direction of the pressing rod. Both the first adjusting portion and the second adjusting portion are threadedly connected to the pressing rod to adjust the height of the pressing rod in the length direction of the pressing rod.

[0018] With the foregoing technical solution, the adjusting member is set in the form of a first adjusting portion and a second adjusting portion. By adjusting the first adjusting portion and the second adjusting portion, the position of the pressing rod in the strip-shaped hole is adjusted; in addition, the height of the pressing rod can also be adjusted through the first adjusting portion and the second adjusting portion to make the lower end of the pressing rod adapt to the height of the connecting portion of the decorative ring, ensuring that the pressing rod presses against the connecting portion to stabilize the decorative ring.

[0019] Further, the measuring workbench is provided with a base, and a self-locking structure is provided on the base. The self-locking structure has a locked state and an unlocked state. When the self-locking structure is in the locked state, the locking member is limited to the locked state. When the self-locking structure is switched from the locked state to the unlocked state, it drives the locking member to switch from the locked state to the unlocked state.

[0020] Adopting the foregoing technical solution, a base is provided on the measuring workbench, and a self-locking structure with a locked state and an unlocked state is further provided on the base. The locked state of the locking member is defined by the self-locking structure, so as to improve the stability of the locking member in the locked state and prevent the locking member from automatically switching from the locked state to the unlocked state, thereby affecting the stability of the decorative ring.

[0021] Furthermore, the self-locking structure includes an operating rod and a locking rod. The operating rod is hinged to the base, one end of the locking rod is hinged to the locking member, and the other end is hinged to the operating rod. During the process of rotating the operating rod, the locking rod drives the locking member to switch between the locked state and the unlocked state. There is a locking step on the locking rod, and the locking step presses against the upper surface of the locking member in the locked state to lock the locking member.

[0022] Adopting the foregoing technical solution, the self-locking structure is arranged in the form of an operating rod and a locking rod. Through the hinge connection between the operating rod and the base, the switching between the locked state and the unlocked state of the locking member can be realized by controlling the rotation of the operating rod, which improves the convenience for installing or removing the decorative ring. After the locking rod is arranged, one end of the locking rod is hinged to the locking member, and the other end is hinged to the operating rod, so that controlling the operating rod drives the locking member to switch between the locked state and the unlocked state through the locking rod, which improves the accuracy of switching between the locked state and the unlocked state of the locking member. A locking step is arranged on the locking rod. In the locked state of the self-locking structure, the locking step presses against the locking member, reducing the possibility of accidental unlocking of the self-locking structure and providing the stability of the locked state of the locking member, further ensuring the stability of the locking member locking the decorative ring.

[0023] Furthermore, the operating rod is provided with a supporting step, and when the locking member is in the locked state, it is supported on the supporting step. The supporting step and the locking step form a locking area for the locking member to stably lock the locking member in the locked state.

[0024] Adopting the foregoing technical solution, a locking area is formed by the supporting step and the locking step, thereby locking the cantilever amount of the locking member, improving the stability of the cantilever beam in the locked state of the locking member. The supporting effect of the supporting step on the cantilever beam ensures that the pressing rod has a suitable height, thereby ensuring that the decorative ring has a relatively uniform height in the circumferential direction of the measuring workbench, and preventing the occurrence of height differences in the circumferential direction of the decorative ring from affecting the measurement accuracy.

[0025] Furthermore, the present invention also discloses a method for measuring a decorative ring of a drum washing machine, which uses the above-mentioned measuring fixture for the decorative ring of the drum washing machine for measurement, and includes the following steps: S1. Confirm that the locking member is in the unlocked state, and place the decorative ring on the measuring workbench; S2. Rotate the decorative ring on the measuring workbench to ensure that the connecting portion on the decorative ring is aligned with the locking member; S3. Switch the locking member to the locked state and lock the decorative ring, thereby locking the decorative ring on the measuring workbench; S4. Position the measuring tool through the first positioning structure and the second positioning structure to measure multiple dimensional data of the decorative ring; S5. Calculate the average value of the multiple data to obtain the size of the decorative ring.

[0026] Adopting the foregoing technical solution, when measuring the inner diameter dimension of the smaller end of the decorative ring, confirm that the locking member is in the unlocked state, place the decorative ring on the measuring workbench, rotate the decorative ring on the measuring workbench so that the connecting portion on the decorative ring and the locking member are distributed radially along the measuring workbench; switch the locking member in the unlocked state to the locked state so that the locking member presses against the connecting portion, thereby stably placing the decorative ring on the measuring workbench. Through the support of the outer wall of the measuring workbench for the decorative ring, it is avoided that the decorative ring has a large measurement error due to deformation during the measurement process. After fixing the decorative ring, use the first positioning structure and the second positioning structure to provide a positioning reference for the measuring tool, ensuring that the two references when the measuring tool measures the size of the decorative ring are in the diameter direction of the measuring workbench, improving the measurement accuracy and reducing the measurement error. When measuring, take the average value of multiple data to further improve the accuracy of the measured dimensional data and reduce the measurement error. Description of the Drawings

[0030] The technical solutions of the present invention will be described in detail below with specific embodiments. These several specific embodiments below can be combined or replaced according to the actual situation, and the same or similar concepts or processes may not be repeated in some embodiments.

[0031] As Figure 1 shown, the present invention provides a measuring jig for a decorative ring of a drum washing machine, which includes a measuring workbench 1 for placing the decorative ring 3 and a locking member 2. As Figure 2 shown, the decorative ring 3 is a conical thin-walled structure, and a connecting portion 31 is provided on the outer periphery of the smaller end of the decorative ring 3. The connecting portion 31 is used for fixedly connecting with the body of the drum washing machine. As Figure 1 and Figure 2 shown, the outer peripheral wall of the measuring workbench 1 is conically arranged and has the same taper as the inner wall of the decorative ring 3. The locking member 2 is arranged on the measuring workbench 1. Specifically, as Figure 1 shown, the locking member 2 is arranged on the end surface of the smaller end of the measuring workbench 1, and a plurality of locking members 2 are provided. The locking member 2 has a locked state and an unlocked state. As Figure 3As shown, in the locked state, the locking member 2 presses against the connecting portion 31 of the decorative ring 3, thereby stabilizing the decorative ring 3 on the measuring workbench 1 to prevent the decorative ring 3 from slipping off the measuring workbench 1 during the measurement process and affecting the accuracy of the measurement result, and also prevents the decorative ring 3 from being at different heights on the measuring workbench 1 and affecting the accuracy of the measurement. In the unlocked state, the locking member 2 avoids the decorative ring 3, which is convenient for the user to place the decorative ring 3 on the measuring workbench 1 or remove the decorative ring 3 from the measuring workbench 1, and avoids the locking member 2 from being worn during the installation and removal of the decorative ring 3; Figure 1 As shown, the end surface of the smaller end of the measuring workbench 1 is provided with a first positioning structure 41 and a second positioning structure 42 which are symmetrical in center. The first positioning structure 41 and the second positioning structure 42 provide positioning references for the measuring tool when measuring the inner diameter of the smaller end of the decorative ring 3. Specifically, the measuring tool is positioned by the first positioning structure 41 and the second positioning structure 42, so that the size measured by the measuring tool is as close as possible to the size in the diameter direction of the measuring workbench 1, thereby reducing the possibility of a large error in the measured size. The decorative ring 3 is supported and placed by the measuring workbench 1 which has the same taper as the inner wall of the decorative ring 3, thereby avoiding deformation and large error in the measurement process of the inner diameter of the smaller end of the decorative ring 3. The decorative ring 3 is stably placed by the locking member 2, thereby reducing the possibility of a height difference of the decorative ring 3 on the measuring workbench 1 during the measurement process, thereby reducing the possibility of the decorative ring 3 affecting the accuracy of the measurement result due to instability. During the measurement process, the first positioning structure 41 and the second positioning structure 42 facilitate the placement of the measuring tool, thereby further reducing the possibility of a large error in the measurement result.

[0032] In this embodiment, in order to facilitate the positioning of the measuring tool, such as Figure 1 and Figure 4 As shown, the first positioning structure 41 and the second positioning structure 42 are both grooves 411, and the groove 411 is arranged on the end face of the smaller end of the measuring workbench 1. The groove 411 penetrates the inner and outer walls of the measuring workbench 1 along the radial direction of the measuring workbench 1. There are multiple grooves 411, and the multiple grooves 411 are paired and arranged symmetrically on the measuring workbench 1. When measuring, the two ends of the measuring tool are respectively located in the two symmetrical grooves 411, so as to ensure as much as possible that the measuring tool measures the size in the diameter direction of the measuring workbench 1. At the same time, the groove 411 positions the measuring tool to improve the stability of the measuring tool during the measurement process.

[0033] In another embodiment, if Figure 5As shown, the first positioning structure 41 and the second positioning structure 42 are both convex ribs 412, and a plurality of convex ribs 412 are provided, and the plurality of convex ribs 412 are arranged symmetrically in pairs; specifically, after the decorative ring 3 is placed on the measuring workbench 1, the end face of the smaller end of the decorative ring 3 is located above the upper surface of the smaller end of the measuring workbench 1, so that a measuring tool such as a vernier caliper can be abutted against the inner wall of the smaller end of the decorative ring 3. When measuring the inner diameter of the smaller end of the decorative ring 3, the two reference points of the measuring tool are respectively abutted against the two symmetrical convex ribs 412 to position the measuring tool, so as to accurately read the value on the measuring tool and prevent the measuring tool from deviating from the diameter direction of the measuring workbench 1.

[0034] In another embodiment, one of the first positioning structure 41 and the second positioning structure 42 is a groove 411 and the other is a convex rib 412. The groove 411 and the convex rib 412 can work together to provide a positioning reference for the measuring tool during the measuring process.

[0035] In addition, the first positioning structure 41 and the second positioning structure 42 may also be provided as scales on the end surface of the smaller end of the measuring workbench.

[0036] In order to prevent the locking piece 2 from affecting the measurement of the measuring tool, when the locking piece 2 is set, the locking piece 2 avoids the first positioning structure 41 and the second positioning structure 42 on the end face of the smaller end of the measuring workbench 1, so that the locking piece 2 avoids the measuring tool. When measuring, the reference point of the measuring tool is directly brought into contact with the first positioning structure 41 and the second positioning structure 42, and the size data can be directly read, which is convenient for the user to more accurately obtain the inner diameter size of the smaller end of the decorative ring 3 from the measuring tool and improves the convenience of the user's measurement.

[0037] In another embodiment, if Figure 3 and Figure 4 As shown, the locking member 2 includes a cantilever beam 21 and a pressing rod 22, one end of the cantilever beam 21 is hinged to the measuring workbench 1, and the other end is a free end 211; in the locked state, the free end 211 extends to the outside of the decorative ring 3 and the pressing rod 22 presses on the connecting portion 31 of the decorative ring 3, and in the unlocked state, the free end 211 is located on the inner side of the outer wall of the smaller end of the measuring workbench 1 to avoid the decorative ring 3; specifically, through the hinge of the cantilever beam 21, the locking state and the unlocking state of the locking member 2 can be switched by rotating the cantilever beam 21, and the pressing rod 22 is arranged on the cantilever beam 21 to ensure that the cantilever beam 21 can be pressed on the connecting portion 31 of the decorative ring 3 when switching from the unlocked state to the locked state, thereby ensuring that the locking member 2 can stably press against the decorative ring 3 on the measuring workbench 1, thereby improving the stability of the decorative ring 3 during the measurement process.

[0038] In order to improve the accuracy of the pressing rod 22 pressing against the decorative ring 3, as shown in FIG. Figure 4As shown in the figure, a strip-shaped hole 212 is provided at the free end 211 of the cantilever beam 21. The length direction of the strip-shaped hole 212 is the same as the length direction of the cantilever beam 21. The pressing rod 22 is located in the strip-shaped hole 212. The pressing rod 22 adjusts its position in the strip-shaped hole 212 through the adjusting member 23. Specifically, when the diameter of the decorative ring 3 installed on the measuring workbench 1 is slightly larger, the fixing state of the pressing rod 22 and the free end 211 can be released through the adjusting member 23, and the position of the pressing rod 22 in the strip-shaped hole 212 is adjusted along the length direction of the strip-shaped hole 212 to ensure that the pressing rod 22 can press against the connecting portion 31 under the locking state of the locking member 2. The pressing rod 22 can be used with decorative rings 3 of different sizes to improve the practicability of the locking of the locking member 2 and ensure that the decorative ring 3 on the measuring workbench 1 can be locked.

[0039] In another embodiment, as Figure 4 and Figure 6 shown, the adjusting member 23 includes a first adjusting portion 231 and a second adjusting portion 232 which are respectively arranged on both sides of the free end 211 of the cantilever beam 21 along the length direction of the pressing rod 22; specifically, the first adjusting portion 231 includes a first adjusting nut 2311 and a first locking piece 2312, the second adjusting portion 232 includes a second adjusting nut 2321 and a second locking piece 2322, and an adjusting thread is provided on the pressing rod 22; when installing the pressing rod 22, the first adjusting portion 231 and the second adjusting portion 232 at the free end 211, after sleeving the first adjusting nut 2311 and the first locking piece 2312 on the pressing rod 22, the pressing rod 22 is passed through the strip-shaped hole 212, and then the second adjusting nut 2321 and the second locking piece 2322 are sleeved on the other side of the free end 211. After the first adjusting nut 2311, the first locking piece 2312, the second adjusting nut 2321 and the second locking piece 2322 are all sleeved on the pressing rod 22, the first locking piece 2312 and the second locking piece 2322 are located between the first adjusting nut 2311 and the second adjusting nut 2321 and the first locking piece 2312 and the second locking piece 2322 press against the side wall of the free end 211; when it is necessary to adjust the position of the pressing rod 22 in the strip-shaped hole 212, the first adjusting nut 2311 is rotated on the pressing rod 22 so that the first locking piece 2312 no longer presses against the free end 211, and then the pressing rod 22 is moved along the length direction of the strip-shaped hole 212 to directly above the connecting portion 31, and then the adjusted first adjusting nut 2311 is rotated towards the free end 211 until the first locking piece 2312 presses against the free end 211 again; when adjusting the position of the pressing rod 22, it can also be adjusted through the second adjusting nut 2321 and the second locking piece 2322.

[0040] In another embodiment, as Figure 6As shown, the adjusting member 23 is arranged in the form of a first adjusting portion 231 and a second adjusting portion. The height of the pressing rod 22 can also be adjusted in the length direction of the pressing rod 22 by threading both the first adjusting portion 231 and the second adjusting portion 232 onto the pressing rod 22. In this embodiment, when the locking member 2 is in the locked state, the first adjusting portion 231 is located above the second adjusting portion 232. Specifically, when it is necessary to adjust the height of the pressing rod 22 downward, the first adjusting nut 2311 is rotated so that the first adjusting nut 2311 moves upward relative to the pressing rod 22, and the first locking piece 2312 is slid upward. At this time, the pressing rod 22 is no longer locked to the free end 211. Then, the second adjusting nut 2321 is rotated so that the second locking piece 2322 moves upward relative to the pressing rod 22 to lock the pressing rod 22 to the free end 211 again, realizing the height adjustment of the pressing rod 22; when it is necessary to adjust the height of the pressing rod 22 downward, the second adjusting portion 232 and the first adjusting portion 231 can be adjusted upward in sequence to achieve the adjustment.

[0041] To improve the stability of the locking member 2 in the locked state, as Figure 6 、 Figure 7 and Figure 8 shown, the measuring workbench 1 is provided with a base 11. The base 11 is provided with a self-locking structure 5. The self-locking structure 5 has a locked state and an unlocked state. When the self-locking structure 5 is in the locked state, the locking member 2 is limited to the locked state. When the self-locking structure 5 is switched from the locked state to the unlocked state, the locking member 2 is driven to switch from the locked state to the unlocked state; specifically, the self-locking structure 5 includes an operating rod 51 and a locking rod 52. The operating rod 51 is hinged to the base 11, and the cantilever beam 21 is also hinged to the base 11. Moreover, the hinged end of the cantilever beam 21 is located inside the hinge point of the operating rod 51. One end of the locking rod 52 is hinged to the locking member 2, and the other end is hinged to the operating rod 51. During the process of rotating the operating rod 51, the locking rod 52 drives the locking member 2 to switch between the locked state and the unlocked state. Specifically, when operating, the user holds the operating rod 51 and rotates the operating rod 51. By the two ends of the locking rod 52 being respectively hinged to the operating rod 51 and the locking member 2, the locking rod 52 is driven to switch between the locked state and the unlocked state; more specifically, one end of the locking rod 52 is hinged to the operating end of the operating rod 51, and the other end is hinged to the middle part of the cantilever beam 21. The locking rod 52 drives the cantilever beam 21 to rotate to realize the switching between the unlocked state and the locked state.

[0042] In this embodiment, as Figure 8As shown, the locking lever 52 has a locking step 521, and the locking step 521 presses against the upper surface of the locking member 2 in the locked state to lock the locking member 2; further, the operating lever 51 is provided with a support step 511. When the locking member 2 is in the locked state, the lower surface of the cantilever beam 21 is supported on the support step 511, and the locking step 521 presses against the upper surface of the cantilever beam 21, so that the support step 511 and the locking step 521 form a locking area for the cantilever beam 21 and lock the cantilever beam 21, thereby improving the stability of the locked state of the locking member 2 and further improving the stability during the measurement of the decorative ring 3.

[0043] In another embodiment, the present invention also discloses a method for measuring a decorative ring of a drum washing machine.

Confirm that the locking member 2 is in the unlocked state, and place the decorative ring 3 on the measurement workbench 1; S2. Rotate the decorative ring 3 on the measurement workbench 1 to ensure that the connecting portion 31 on the decorative ring 3 is aligned with the locking member 2; S3. Switch the locking member 2 to the locked state and press down the connecting portion 31 to lock the decorative ring 3, thereby locking the decorative ring 3 on the measurement workbench 1; S4. Position the measuring tool through the first positioning structure 41 and the second positioning structure 42 to measure multiple dimension data of the decorative ring 3; S5. Calculate the average value of multiple data to obtain the size of the decorative ring 3.

[0044] Ensuring that the locking member 2 is in the unlocked state before placing the decorative ring 3 is to avoid abrasion caused by friction between the decorative ring 3 and the free end 211 of the cantilever beam 21 or the pressing rod 22 during the installation of the decorative ring 3, and ensure that the decorative ring 3 is not damaged before and after measurement; rotating the decorative ring 3 so that the connecting portion 31 is aligned with the pressing rod 22 to ensure the stability of the decorative ring 3 during the measurement process and avoid affecting the measurement accuracy due to different heights of the decorative ring 3 in the circumferential direction during the measurement process; the first positioning structure 41 and the second positioning structure 42 are set in the form of grooves 411 or ribs 412 to position the two measurement reference points of the measuring tool (such as a vernier caliper), ensure that the dimensions are measured in the diameter direction of the measurement workbench 1, improve the measurement accuracy, and reduce the measurement error; multiple data are obtained through multiple groups of pairwise axisymmetric grooves 411 or ribs 412 during the measurement process, and the average value of multiple data is used to obtain the inner diameter size of the smaller end of the decorative ring 3, further reducing the measurement error. The decorative ring 3 is supported by the measurement workbench 1 to avoid deformation of the thin-walled decorative ring 3 during the measurement process and affect the measurement accuracy.

[0045] In addition to the above preferred embodiments, the present invention has other implementation manners. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection claimed by the present invention.
