In one embodiment of the present application, a rotating screen 10a is provided, which can be applied to a dishwasher, or to any other electrical appliance, such as a washing machine, a steam oven, etc. In the embodiment provided by the present application, the rotating screen 10a is applied to a dishwasher to display the washing process and washing time of the dishwasher, and is installed on the above-mentioned door body 10.

[0049] like Figure 2 , Figure 3 and Figure 5As shown, the rotating screen 10a includes a screen assembly 400 and a hinge assembly 100 as in any of the embodiments described below, and also includes a second component 200 and a driving assembly 300. The screen assembly 400 is connected to the first component 110 described below and rotates synchronously with the first component 110. The driving assembly 300 is used to drive the first component 110 to rotate relative to the second component 200 described below, thereby realizing the rotation of the screen assembly 400 to open and close.

[0050] Combination Figure 3 and Figure 5 , Figure 3 and Figure 5 A schematic diagram of an exploded view of a rotating shaft assembly 100 in an embodiment of the present application is shown. In an embodiment of the present application, a rotating shaft assembly 100 is provided, which can be applied to the above-mentioned rotating screen 10a, and can also be applied to other components connected in rotation, such as a door connected in rotation.

[0051] like Figure 3 As shown, the rotating shaft assembly 100 includes a first component 110 and a connecting shaft 120. The first component 110 includes a body 111 and a stopper 112 detachably connected to the body 111. The connecting shaft 120 includes a shaft body 122. The shaft body 122 is rotatably connected to the first component 110 so that the first component 110 and the shaft body 122 can rotate relative to each other. When the stopper 112 is installed on the body 111, the stopper 112 limits the shaft body 122 and fixes the shaft body 122 relative to the first component 110 at least in the circumferential direction.

[0052] In some embodiments, the body 111 is provided with a connection hole 1111. Figure 4 and Figure 7 As shown, the limiting member 112 is located on one side of the connecting hole 1111. Figure 8 As shown, the shaft body 122 can be detachably passed through the connecting hole 1111, and the limiting member 112 abuts against the shaft body 122 in the axial direction of the shaft body 122 to rotationally connect the second component 200 and the first component 110, and the shaft body 122 is axially limited by the limiting member 112 to prevent the shaft body 122 from moving in the axial direction.

[0053] like Figure 3 and Figure 5 As shown, the rotating screen 10a further includes a second component 200, and the connecting shaft 120 is detachably connected to the second component 200. Figure 5 As shown, the connecting shaft 120 also includes a connected connecting seat 121 , and the connecting seat 121 is used to be connected to the second component 200 .

[0054] The shaft assembly 100 in the above scheme, on the one hand, by detachably connecting the shaft body 122 to the second component 200 through the connecting seat 121, when the shaft body 122 is assembled, the shaft body 122 that rotatably connects the second component 200 and the first component 110 only has relative movement with the first component 110, thereby avoiding friction damage caused by relative rotation between the shaft body 122 and the second component 200, and between the shaft body 122 and the first component 110. In addition, the gap between the shaft body 122 and the mating part due to friction is avoided from increasing and affecting the stability of the connection. On the other hand, the shaft body 122 is also axially limited by the limiting member 112, so that when the second component 200 and the first component 110 rotate relative to each other, the shaft body 122 will not move in the axial direction, thereby avoiding the instability of the rotation connection caused by the movement of the shaft body 122, thereby improving the stability of the rotation connection between the second component 200 and the first component 110, and ensuring the reliability and durability of the overall structure.

[0055] like Fig. 9 As shown, in one embodiment, the circumferential surface of the shaft body 122 is concavely provided with an annular limiting groove 1221, and the limiting member 112 is annular in structure to prevent the limiting member 112 from interfering with the rotation of the shaft body 122, and as shown in FIG. Figure 8 As shown, when the shaft body 122 is assembled, the limiting member 112 is at least partially detachably inserted into the limiting groove 1221 to abut against the groove wall of the limiting groove 1221 in the axial direction of the shaft body 122, thereby achieving partial abutment of the limiting member 112 against the groove wall of the limiting groove 1221 to limit the shaft body 122 in the axial direction.

[0056] like Fig.10 As shown, in one embodiment, the limiting member 112 includes a limiting portion 1121, and the end surface of the limiting portion 1121 facing the shaft body 122 is concavely provided with an arc groove 11211 adapted to the shaft body 122, and the arc groove 11211 has an opening at one end facing the shaft body 122, as shown in FIG. Figure 8 As shown, when the limit member 112 is connected to the main body 111, the limit portion 1121 is at least partially inserted into the limit groove 1221 and the shaft body 122 is partially inserted into the arc groove 11211, so that the limit member 112 does not interfere with the rotation of the shaft body 122, and the matching area between the shaft body 122 and the arc groove 11211 is large and the friction force is uniform.

[0057] In other embodiments, the limiting portion 1121 may also be a plate body without a slot or with a slot structure of other polygonal structures. When the limiting member 112 is connected to the main body 111, the plate body portion can be located in the limiting slot 1221. When the shaft body 122 moves in the axial direction, the limiting portion 1121 may also abut against the slot wall of the limiting slot 1221 in the axial direction of the shaft body 122 to achieve a limiting effect.

[0058] like Figure 3 and Figure 5 As shown, in the present embodiment, there are two connecting shafts 120, and the two connecting shafts 120 are symmetrically distributed. Accordingly, there are two connecting holes 1111 and two limiting members 112, and they are arranged one-to-one with the connecting shafts 120. At this time, in order to improve the adaptability of the limiting members 112, each limiting member 112 is provided with a symmetrically arranged limiting portion 1121 to respectively adapt to the two connecting shafts 120.

[0059] In one embodiment, the portion of the stopper 112 that contacts the shaft 122 is made of a self-lubricating material to reduce the friction of the relative rotation between the stopper 112 and the shaft 122. Self-lubricating materials refer to materials that can reduce friction and wear without additional lubricants. Such materials usually have a lower friction coefficient and higher wear resistance, can work in dry or polluted environments, reduce maintenance costs and improve equipment reliability, such as polytetrafluoroethylene (PTFE), nylon, polyimide, polyoxymethylene (POM), etc.

[0060] like Figure 4 and Fig.10 As shown, in one embodiment, the limiter 112 is buckled and connected to the first component 110. In other embodiments, the limiter 112 can also be connected by screws, or other components for limiting the limiter 112 are added to realize the connection between the limiter 112 and the first component 110.

[0061] like Figure 4 and Figure 7 As shown, in one embodiment, the main body 111 is provided with a placement groove 1112 which is arranged perpendicular to the axis of the shaft body 122, and the placement groove 1112 has an opening. The limiting member 112 can be slidably adjusted along the placement groove 1112 and then fixedly connected to the main body 111 and limit the shaft body 122. The placement groove 1112 can guide the installation of the limiting member 112 to facilitate the installation of the limiting member 112.

[0062] like Figure 4 As shown, the wall of the placement slot 1112 is provided with a snap-fitting slot 1113. Fig.10 As shown, the stopper 112 is provided with a buckling protrusion 11231 corresponding to the buckling groove 1113, and the installation direction of the stopper 112 is perpendicular to the axial direction of the shaft body 122, which is convenient for the installation of the stopper 112 on the one hand, and can also prevent the shaft body 122 from moving along its axial direction to drive the stopper 112 to move. In other embodiments, a protrusion can also be provided on the body 111, and a groove for buckling corresponding to the protrusion can be provided on the circumference of the stopper 112 to achieve a buckling connection between the two.

[0063] like Fig.10As shown, in one embodiment, the stopper 112 includes a main body 1122 and a buckle portion 1123 connected to the main body 1122, one end of the buckle portion 1123 is connected to the main body 1122, and the other end is a free end, and a buckle protrusion 11231 is located at the free end, so that when the buckle protrusion is subjected to force, the buckle portion 1123 can be slightly deformed relative to the main body 1122, so as to facilitate insertion into the placement groove 1112, and after the stopper 112 is installed in place, the buckle portion 1123 is reset so that the buckle protrusion is partially inserted into the buckle groove 1113. Fig.10 As shown, in order to facilitate assembly, an end of the snap-fit ​​protrusion away from the main body 1122 is provided with an inclined surface for guiding.

[0064] like Figure 3 and Figure 4 As shown, in one embodiment, the shaft assembly 100 also includes a friction reducing member 130 sleeved on the outer periphery of the shaft body 122, the friction reducing member 130 is made of self-lubricating material, and the friction reducing member 130 is at least partially located between the hole wall of the connecting hole 1111 and the outer peripheral surface of the shaft body 122 in the radial direction of the shaft body 122, so as to reduce the friction between the shaft body 122 and the first component 110, thereby reducing the friction loss of components and the friction consumption kinetic energy.

[0065] like Fig.11 As shown, in one embodiment, the friction reducing member 130 abuts against the first component 110 or the second component 200 in the circumferential direction of the shaft body 122 to rotate synchronously, so that the friction reducing member 130 and the first component 110, or the friction reducing member 130 and the second component 200 are synchronized, so that there is friction only between the friction reducing member 130 and the hole wall of the connecting hole 1111, or there is friction only between the friction reducing member 130 and the outer peripheral surface of the shaft body 122, thereby protecting the shaft body 122 and the connecting hole 1111 and preventing them from being damaged due to friction.

[0066] like Fig.12 As shown, in one embodiment, the friction reducing member 130 includes a head 131 and a friction portion 132 connected to each other, the friction portion 132 is located between the hole wall of the connecting hole 1111 and the outer peripheral surface of the shaft body 122, and the head 131 is located outside the connecting hole 1111 to abut against the first component 110 or the second component 200. In this embodiment, the head 131 and the friction portion 132 are distributed along the axial direction, and in other embodiments, the head 131 can also be protruded from the peripheral surface of the friction portion 132.

[0067] In this embodiment, the friction reducing member 130 abuts against the first component 110 to rotate synchronously, and at this time, there is friction between the friction reducing member 130 and the circumferential surface of the shaft body 122; in other embodiments, the friction reducing member 130 may also abut against the second component 200, and at this time, there is friction between the friction reducing member 130 and the hole wall of the connecting hole 1111 of the first component 110.

[0068] like Fig.12 As shown, in one embodiment, the head 131 includes a contact surface 1311, such as Figure 4 and Figure 7 As shown, the end surface of the body 111 for opening the connection hole 1111 is convexly provided with abutment protrusions 1114, as shown in FIG. Fig.11 As shown, the abutting surface 1311 abuts against the abutting protrusion 1114 in the circumferential direction of the shaft body 122, so that the friction reducing member 130 abuts against the first component 110 to rotate synchronously, so that the friction reducing member 130 only has friction between the circumferential surface of the shaft body 122. In other embodiments, a protrusion may be provided on the second component 200 to abut against the abutting surface 1311, so that the friction reducing member 130 abuts against the second component 200.

[0069] like Figure 6 As shown, the second component 200 includes at least one guide component 210 for guiding and at least one fastener for fastening. The guide component 210 and the fastener are arranged at intervals and both cooperate with the connecting shaft 120, so that when the connecting shaft 120 needs to be installed to the second component 200, the connecting shaft 120 can be pre-positioned by the guide component 210 first, thereby facilitating assembly.

[0070] When in use, it is only necessary to insert the shaft body 122 of the connecting shaft 120 into the connecting hole 1111, and then move along the axial direction of the shaft body 122 to make the shaft body 122 pass through the connecting hole 1111. When the shaft body 122 is installed in place, the limit member 112 is placed and clamped in the placement groove 1112. At this time, the limit portion 1121 is partially inserted into the limit groove 1221 and the shaft body 122 is partially inserted into the arc groove 11211. Then, the connecting seat 121 of the connecting shaft 120 is aligned with the guide component 210 of the second component 200 to pre-position the installation of the connecting seat 121 and the second component 200 through the guide component 210. In the pre-positioned state, the two are fastened by fasteners to complete the assembly.

[0071] like Figure 6 As shown, the connection base 121 is provided with a mounting hole 1213 for connecting to the second component 200. In this embodiment, the mounting hole 1213 is used to fasten the connection base 121 to the second component 200 using a fastener such as a screw.
