[0046] like Figure 3 and Figure 4 As shown, the rotating shaft assembly 100 includes a connecting bracket 110, a first component 120 and a shaft body 130. Among them, the first component 120 includes a main body 123 and a stopper 124, the shaft body 130 is connected between the connecting bracket 110 and the main body 123 so that the two form a rotating structure, the stopper 124 is detachably connected to the main body 123, and after the stopper 124 is installed to the main body 123, the stopper 124 can limit the shaft body 130 and make the shaft body 130 fixed relative to the main body 123 at least in the circumferential direction, so that the shaft body 130 and the main body 123 rotate synchronously, avoiding the relative movement between the shaft body 130 and the main body 123, so that when the shaft body 130 is assembled, the shaft body 130 only rotates relative to the first component 120, avoiding the friction damage caused by the relative rotation between the shaft body 130 and the main body 123 and the shaft body 130 and the second component 200.

[0047] like Figure 6 As shown, in this embodiment, the shaft body 130 includes a rotating portion 131 and a limiting portion 132 that are connected and coaxially arranged, and the limiting portion 132 includes an abutting surface 133, and the abutting surface 133 abuts against the limiting member 124 in the circumferential direction of the shaft body 130 so that the shaft body 130 is fixed relative to the main body 123 in the circumferential direction, thereby realizing synchronous rotation with the main body 123. In other embodiments, the limiting member 124 can also adopt other matching methods with the shaft body 130, for example, the limiting member 124 is partially inserted into the shaft body 130, which can also realize that the shaft body 130 is fixed relative to the main body 123 in the circumferential direction.

[0048] like Figure 3 and Figure 6As shown, the main body 123 is provided with a recessed groove 121 which is coaxially arranged with the connecting hole 117 and has an open opening for accommodating the shaft body 130. Figure 5 As shown, the connecting bracket 110 is provided with a connecting hole 117 for passing the shaft 130. Figure 7 and Figure 8 As shown, the shaft body 130 is inserted into the connection hole 117 and at least partially placed in the groove 121. It can be understood that each shaft body 130 corresponds to at least one groove 121 and at least one connection hole 117. Figure 3 and Figure 4 As shown, in the present embodiment, the number of the shaft bodies 130 is two, and correspondingly, the second component 200 includes connecting brackets 110 corresponding to the two shaft bodies 130, each connecting bracket 110 is provided with a connecting hole 117 corresponding to the corresponding shaft body 130, and the main body 123 is provided with grooves 121 corresponding to the two shaft bodies 130, so as to form two sets of rotational fit between the main body 123 and the second component 200, thereby making the rotational connection between the main body 123 and the second component 200 more stable.

[0049] like Figure 6 and Figure 8 As shown, in one embodiment, the main body 123 includes a connecting surface 122, and the groove 121 is recessed in the connecting surface 122, and when a portion of the limiting portion 132 is placed in the groove 121, the abutting surface 133 is flush with the connecting surface 122. In other embodiments, the groove 121 can also be configured such that a side wall is provided with a plane adapted to the abutting surface 133, and when a portion of the limiting portion 132 is placed in the groove 121, the abutting surface 133 is flush with the plane, so that the abutting surface 133 abuts against the limiting member 124 in the circumferential direction of the shaft body 130 to rotate synchronously with the main body 123.

[0050] like Figure 6 As shown, in the present embodiment, the limiting portion 132 is a cross-section formed by a recessed cylindrical structure portion. Preferably, in the axial direction of the shaft body 130, the length of the limiting member 124 is adapted to the length of the abutment surface 133 so that the limiting member 124 can limit the shaft body 130 in the axial direction of the shaft body 130 to prevent the shaft body 130 from axially moving during rotation.

[0051] In this embodiment, the abutment surface 133 is a plane. In other embodiments, the limiting portion 132 may also adopt a polygonal column structure or an elliptical column structure. In this case, the abutment surface 133 is a partial circumference of a polygonal column or a partial circumference of an elliptical column. The end face of the limiting member 124 used to abut the limiting portion 132 may be concavely provided with a groove 121 with a polygonal or elliptical cross-section that is compatible with the limiting portion 132, thereby achieving abutment between the limiting member 124 and the abutment surface 133.

[0052] like Figure 6and Figure 8 As shown, in one embodiment, the groove 121 is an arc-shaped structure coaxially arranged with the shaft body 130, and the wall surface of the groove 121 is at least partially in contact with the circumference of the limiting portion 132, so that the limiting portion 132 is supported by the wall surface of the groove 121 to prevent the limiting portion 132 from being deformed or even broken due to excessive torsional force during rotation.

[0053] like Figure 6 As shown, in one embodiment, the main body 123 is provided with a slot 1233 arranged parallel to the connecting surface 122, and the limiting member 124 can be slidably adjusted along the slot 1233 and then fixedly connected to the main body 123 and limit the shaft 130.

[0054] like Figure 6 As shown, the main body 123 also includes a protrusion 1232 protruding from the connecting surface 122, and the two protrusions 1232 are arranged opposite to each other and extend toward each other at one end away from the connecting surface 122, so that a slot 1233 is formed between the protrusion 1232 and the connecting surface 122, and the limit member 124 can be slidably adjusted along the slot 1233 and then fixedly connected to the main body 123, and the part of the slot 1233 extending toward each other can limit the limit member 124 in a direction perpendicular to the connecting surface 122, so as to prevent the limit member 124 from loosening and affecting the circumferential limitation of the shaft 130 by the limit member 124.

[0055] In this embodiment, the stopper 124 is connected to the main body 123 through a detachable fixing member 140, and the connecting surface 122 is located on the main body 123. The main body 123 is provided with a fixing hole 1231 for connecting the fixing member 140. In this embodiment, the fixing member 140 is a mounting screw, and the fixing hole 1231 is a threaded hole. In other embodiments, the fixing member 140 and the fixing hole 1231 can also be connected by snap-fit. Figure 6 As shown, the groove 121 is opened in the main body 123, and the limiting member 124 at least partially covers the opening of the groove 121, so that when part of the limiting portion 132 is placed in the groove 121, the limiting member 124 abuts against the abutting surface 133, thereby abutting against the abutting surface 133 in the circumferential direction of the shaft body 130 through the limiting member 124, so that the shaft body 130 and the main body 123 rotate synchronously.

[0056] like Figure 5 As shown, in one embodiment, the connecting bracket 110 is provided with a through hole 116 which is aligned with the fixing member 140 and arranged along the installation direction of the fixing member 140 , so as to facilitate the installation of the fixing member 140 through the through hole 116 .

[0057] like Figure 5As shown, in one embodiment, the connecting bracket 110 includes a connecting portion 111 and a rotating protrusion 112 connected to each other, wherein the connecting portion 111 is detachably connected to the second component 200, and the rotating protrusion 112 is protruding from the connecting portion 111, and the connecting hole 117 is opened in the rotating protrusion 112, so that when the shaft body 130 is installed to the connecting hole 117, the axis of the shaft body 130 is not on the plane where the connecting portion 111 is located, thereby leaving a rotation space for the main body 123 to rotate relative to the connecting bracket 110.

[0058] See also Figure 7 In one embodiment, there are two rotating protrusions 112, and the two rotating protrusions 112 are arranged at intervals and are respectively located on both sides of the groove 121. The connecting holes 117 located at the two rotating protrusions 112 are coaxially arranged. Accordingly, the limiting portion 132 is located in the middle of the shaft body 130, and both ends of the limiting portion 132 are rotating portions 131 for passing through the connecting holes 117, so that the force on the shaft body 130 is more uniform.

[0059] like Figure 4 As shown, the connecting bracket 110 is detachably connected to the second component 200. Specifically, in this embodiment, the connecting portion 111 is used to connect the second component 200. The second component 200 includes at least one guide component 220 for guiding and at least one fastener 230 for fastening, wherein the guide component 220 and the fastener 230 are arranged at intervals and both cooperate with the connecting bracket 110, so that when the connecting bracket 110 needs to be installed to the second component 200, the connecting bracket 110 can be pre-positioned by the guide component 220 first, thereby facilitating assembly.

[0060] The rotating screen 10a provided in this embodiment can be installed by first inserting the shaft 130 into the connecting hole 117 of the connecting bracket 110, then synchronously moving the connecting bracket 110 and the shaft 130 until the shaft 130 is inserted into the groove 121 provided by the main body 123, then inserting the stopper 124 into the slot 1233 and connecting the stopper 124 to the fixing hole 1231 through the fixing member 140, at which time there is a circumferential abutment force between the stopper 124 and the shaft 130, so that the shaft 130 and the first component 120 rotate synchronously, and the shaft assembly 100 is installed. Then, the shaft assembly 100 is installed on the second component 200, firstly guiding and pre-positioning the connecting bracket 110 through the guide component 220, and then fastening the connecting bracket 110 to the second component 200 through the fastener 230, so as to realize the rotation connection between the shaft assembly 100 and the second component 200.

[0061] like Figure 5As shown, in one embodiment, the second component 200 includes a mounting surface 210 for connecting the connecting bracket 110, the connecting bracket 110 is provided with a fastening hole 115, and the fastener 230 passes through the second component 200 and is connected to the fastening hole 115, so as to achieve the connection bracket 110 is installed to the second component 200. In this embodiment, the fastener 230 is a screw, and the fastening hole 115 is a threaded hole. In other embodiments, the fastener 230 and the fastening hole 115 can also be connected by snap-fitting.

[0062] like Figure 5 As shown, the guide member 220 further includes a positioning member 221 protruding from the mounting surface 210, and the connecting bracket 110 is provided with a positioning hole 113 adapted to the positioning member 221, and the positioning member 221 and the positioning hole 113 are transition fit or interference fit, so that the assembly of the connecting bracket 110 is positioned through the positioning member 221 and the positioning hole 113, thereby facilitating the installation of the fastener 230 to the fastening hole 115. Figure 5 As shown, in this embodiment, the positioning hole 113 is opened in the connecting portion 111. In this embodiment, in order to simplify the structure of the connecting bracket 110, the through hole 116 and the positioning hole 113 for installing the fixing member 140 are the same hole. In other embodiments, the through hole 116 and the positioning hole 113 can also be staggered.

[0063] like Figure 5 As shown, in one embodiment, the guide component 220 also includes a guide member 222 protruding from the mounting surface 210, the guide member 222 is located on the outer periphery of the positioning member 221, and the distance between the guide member 222 and the mounting surface 210 is greater than the distance between the positioning member 221 and the mounting surface 210, so that the guide member 222 first contacts the connecting bracket 110, and the connecting bracket 110 is provided with a guide hole 114 adapted to the guide member 222, and the matching clearance between the guide member 222 and the guide hole 114 is greater than the matching clearance between the positioning member 221 and the positioning hole 113, so that after the guide member 222 is inserted into the guide hole 114, the positioning member 221 is inserted into the positioning hole 113, thereby realizing the pre-positioning of the connecting bracket 110 through the guide member 222, and then accurately positioning the connecting bracket 110 through the positioning member 221. Figure 5 As shown, in this embodiment, the guide hole 114 is opened in the connecting portion 111 .

[0064] like Figure 5 As shown, in one embodiment, the diameter of the end of the guide member 222 away from the mounting surface 210 is gradually reduced, so that after the guide member 222 is inserted into the guide hole 114, during the process of inserting the guide member 222 into the guide hole 114, the corresponding positions of the connecting bracket 110 and the positioning hole 113 are gradually accurate.

[0065] like Figure 5As shown, in one embodiment, there are multiple guide members 222, which are distributed circumferentially around the positioning member 221 to jointly limit the connection bracket 110 in the circumferential direction, so as to avoid that after a single guide member 222 positions the connection bracket 110, the connection bracket 110 rotates and causes the positioning member 221 to fail to position smoothly. In this embodiment, there are two guide members 222, and the two guide members 222 are respectively located on both sides of the positioning block.

[0066] The rotating shaft assembly 100 provided in the above scheme is provided with a detachably connected stopper 124 on the first component 120, so that after the stopper 124 is installed on the main body 123, it can interact with the shaft body 130 in the circumferential direction to achieve the fixation of the shaft body 130 relative to the main body 123 in the circumferential direction, thereby avoiding the relative movement between the shaft body 130 and the main body 123 when the connecting bracket 110 and the first component 120 rotate relative to each other, so that when the shaft body 130 is assembled, the shaft body 130 only rotates relative to the connecting bracket 110, thereby avoiding the friction damage caused by the relative rotation between the shaft body 130 and the connecting bracket 110 and the shaft body 130 and the main body 123. Such damage will cause the gap between the shaft body 130 and the mating part to increase, thereby affecting the stability of the connection. Through the above design, the stability of the rotational connection between the connecting bracket 110 and the first component 120 is significantly improved, ensuring the reliability and durability of the overall structure.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
