[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0048] The present application provides a fastening device for an adjustment foot, and the adjustment foot can be, for example, an adjustable foot of a household appliance such as a washing machine, a dryer, or a refrigerator. Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the structure of the fastening device provided in the embodiment of the present application. Figure 2 The fastening device 100 includes a fixing member 110, a movable member 120 and a rotating member 130. The fastening device 100 is used, for example, to be installed on a Figure 2 An adjustment foot 200 is shown.
[0049] The adjusting foot 200 includes a bolt 210 and a nut 220. The bolt 210 includes a base 211 and a screw rod 212 connected to the base 211. One end of the screw rod 212 away from the base 211 is used to connect to the bottom support of the household appliance. The nut 220 is screwed to the screw rod 212 and is located between the bottom support of the household appliance and the base 211. It can be understood that the bolt 210 is used to support the household appliance, and the bolt 210 is rotated relative to the bottom support of the household appliance to adjust the height of the foot. The nut 220 is used to lock the bolt 210 to prevent the bolt 210 from rotating relative to the bottom support, thereby fixing the height of the foot.
[0050] The fixing member 110 is used to be sleeved on the base 211, and is used to limit the rotation of the bolt 210 relative to the fixing member 110. The movable member 120 is slidably connected to the fixing member 110 to slide toward or away from the fixing member 110 along the axial direction of the bolt 210. The movable member 120 is provided with a limiting groove 121 with an opening facing the nut, and the limiting groove 121 is used to accommodate the nut 220 to limit the rotation of the nut 220 relative to the movable member 120. The rotating member 130 is rotatably connected to the fixing member 110 and is threadedly connected to the movable member 120, and is used to rotate axially relative to the fixing member 110 so that the movable member 120 moves toward or away from the nut 220.
[0051] In actual application, the user needs to first sleeve the fixing member 110 on the base 211 and fix the fixing member 110 to prevent the bolt 210 from rotating. After that, the user can rotate the rotating member 130 to make the movable member 120 move toward the nut 220 until the nut 220 is completely accommodated in the limiting groove 121. It can be understood that under the rotation restriction of the movable member 120, the nut 220 is locked, thereby preventing the nut 220 from gradually loosening due to vibration during the operation of the household appliance, causing the height of the foot to change, resulting in the unevenness of the household appliance. Especially for clothing processing equipment, the unevenness of the clothing processing equipment will cause severe shaking during operation and generate huge noise, causing the motor to wear or even fail to work properly.
[0052] The fastening device 100 for the adjusting foot provided in the embodiment of the present application limits the rotation of the bolt 210 by the fixing part 110, and adjusts the relative position of the movable part 120 by rotating the rotating part 130 until the movable part 120 is sleeved on the nut 220 and limits the relative rotation of the nut. Since the movable part 120 is connected to the fixing part 110 in a sliding manner, the nut 220 cannot rotate relative to the bolt 210 and is thus locked. This can prevent the height change of the adjusting foot 200 of the household appliance due to the loosening of the nut 220, resulting in the unevenness of the entire machine, which in turn causes a greater malfunction.
[0053] For further information, see Figure 3 , Figure 3An exploded view of a fastening device provided in an embodiment of the present application.
[0054] The fixing member 110 includes a fixing portion 111 and a slide groove 112 provided on the outer wall of the fixing portion 111. The fixing portion 111 is sleeved on the base 211. The slide groove 112 extends along the axial direction of the bolt 210. The movable member 120 includes a limiting portion 122 and a slide rail 123. The limiting portion 122 is provided with the limiting groove 121. The slide rail 123 is connected to one end of the limiting portion 122 away from the nut 220. The slide groove 112 cooperates with the slide rail 123 to enable the movable member 120 to be slidably connected to the fixing member 110.
[0055] Exemplarily, the fixing portion 111 is cylindrical in shape as a whole, and is formed with a groove 113 opening toward the base 211. The base 211 is, for example, prism-shaped, and the shape of the groove 113 matches the shape of the base 211. The groove 113 is used to accommodate the base 211 to limit the rotation of the bolt 210 relative to the fixing member 110.
[0056] The limiting portion 122 is, for example, also cylindrical and forms a limiting groove 121 opening toward the nut 220. The nut 220 is, for example, an octagonal nut, and the limiting groove 121 matches the shape of the nut 220, so that when the nut 220 is accommodated in the limiting groove 121, the limiting groove 121 limits the relative rotation of the nut 220. The bottom wall of the limiting groove 121 is opened to reduce the weight of the limiting portion.
[0057] The outer wall of the fixing portion 111 is, for example, cylindrical and coaxial with the bolt 210, and a plurality of slide grooves 112 are provided, and the plurality of slide grooves 112 are evenly spaced and distributed on the outer wall of the fixing portion 111. Correspondingly, a plurality of slide rails 123 are provided, and the plurality of slide rails 123 are slidably connected with the plurality of slide grooves 112 in a one-to-one correspondence. The outer wall of the limiting portion 122 is, for example, also cylindrical and coaxial with the bolt 210.
[0058] In some embodiments, the slide rail 123 includes a first outer wall 1231 away from the bottom of the slide groove 112 , and a threaded portion 124 is protruded from the first outer wall 1231 . The rotating member 130 is sleeved on the slide rail 123 and screwed to the threaded portion 124 .
[0059] See also Figure 4-Figure 5 , Figure 4 A schematic diagram of the structure of a rotating member provided in an embodiment of the present application, Figure 5 The rotating member 130 is a schematic structural diagram from another perspective of the embodiment of the present application. The rotating member 130 is, for example, cylindrical with an opening at the bottom, and its inner wall is provided with threads for screwing with the threaded portion 124 .
[0060] In some embodiments, the fixing member 110 further includes a shaft body portion 114, which is convexly disposed on the end surface of the fixing member 111 away from the base 211. The fastening device 100 further includes a bearing 140. The bearing 140 includes an inner ring 141 and an outer ring 142, and the outer ring 142 can rotate axially relative to the inner ring 141. The bearing 140 is sleeved on the shaft body portion 114 and the inner ring 141 is fixedly connected to the shaft body portion 114. The rotating member 130 is sleeved on the bearing 140 and fixedly connected to the outer ring 142, so that the rotating member 130 is rotatably connected to the fixing member 110.
[0061] See also Figure 6-Figure 7 , Figure 6 A schematic diagram of the structure of a fixing member provided in an embodiment of the present application, Figure 7 A schematic diagram of the structure of the fixing member provided in an embodiment of the present application from another perspective. The fixing member 110 also includes a rod body 115, which is connected to one end of the shaft body portion 114 away from the fixing portion 111 and extends along the axial direction of the bolt 210. The rod body 115 is, for example, inserted through an opening at the bottom of the rotating member 130. Preferably, the rod body 115 is a multi-faceted rod, which is used to facilitate clamping by an external tool such as an electric gun to fix the fixing member 110. In some embodiments, the end of the rod body 115 away from the shaft body portion 114 is also connected to a support seat (not shown in the figure), and the support seat is in contact with the base plate to support the fastening device 100 and the adjustment foot 200.
[0062] In some embodiments, the fastening device 100 further includes a fastener 150. The fastener 150 is used to be fixedly connected to the fixed member 110 and the rotating member 130 to limit the rotation of the rotating member 130 relative to the fixed member 110. Optionally, the fastener 150 is a fastening screw. A threaded hole 131 is provided at the bottom of the rotating member 130, and a threaded groove 116 is provided on the fixed member 110, which is opposite to the threaded hole 131. The two ends of the fastener 150 are screwed to the threaded hole 131 and the threaded groove 116, respectively.
[0063] Preferably, the end surface of the fixed portion 111 away from the base 211 is provided with a circle of thread grooves 116, and the rotating member 130 rotates to face one of the thread grooves 116. In practical applications, after the rotating member 130 is rotated until the nut 220 is accommodated in the limiting groove 121, the rotating member 130 is slightly rotated to make the threaded hole 131 face a nearby thread groove 116, and then the fastener 150 is screwed with the threaded hole 131 and a thread groove 116 opposite to the threaded hole 131. It can be understood that after the rotating member 130 is locked to the fixed member 110, the position of the movable member 120 is fixed, and the movable member 120 locks the nut 220 to prevent the height of the adjustment foot 200 from changing.
[0064] The embodiment of the present application provides a method of limiting the rotation of the bolt 210 through the fixing part 110 and limiting the relative rotation of the nut through the movable part 120. After the fastener 150 locks the rotating part 130 to the fixing part 110, the movable part 120 is fixed relative to the fixing part 110, so that the nut 220 can be locked, thereby preventing the adjustment foot 200 of the household appliance from changing in height due to the loosening of the nut 220, resulting in unevenness of the entire machine, and further causing a larger malfunction.
[0065] The present application also provides an adjustment foot assembly, for example, see Figure 8 , Figure 8 The schematic diagram of the structure of the adjusting foot assembly provided in the embodiment of the present application is as follows: The adjusting foot assembly 11 is applied to a clothes processing device, and includes the adjusting foot 200 and the fastening device 100 mentioned above.
[0066] The adjusting foot assembly 11 provided in the embodiment of the present application, by locking the nut 220 through the fastening device 100, can prevent the adjusting foot 200 of the clothing processing equipment from changing in height due to the loosening of the nut 220, causing the entire machine to be uneven, and thus causing greater malfunctions.
[0067] The present application also provides a clothes processing device, for example, see Fig. 9 , Fig. 9 This is a schematic diagram of the structure of a clothes processing device provided in an embodiment of the present application. Fig.10 This is a schematic diagram of the structure of the adjustment foot assembly provided in the embodiment of the present application installed on the bottom support.
