[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0034] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For purposes of simplicity of the present disclosure, the following description will refer to specific examples of the present application. It is understood that these are merely examples and are not intended to limit the present application in any manner. Furthermore, the present application can be implemented in a variety of environments and applications, not just those described in the following examples. Also, the present application can be used in different examples with different numbers of components and / or different arrangements of components. Furthermore, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize that other processes can be applied and / or other materials can be used.

[0035] For purposes of the description hereinafter, the terms "upper", "lower", "right", "left", "rear", "front", "vertical" and "horizontal" as can be understood in the context of the figures are used to describe the orientation of the device as shown in the figures. These relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, the elements described as on the "lower" side of other elements or features would then be oriented on the "upper" sides of other elements or features. The device can be oriented in any direction and the spatially relative terms are intended to encompass such variations as well. The term "front" can refer to the front of another part or feature (e.g., front of the device). The terms "front" and "back" can also be used to describe the orientation of the device in use or operation.

[0036] With reference to Figure 1 and Figure 2 , the embodiments of the present application provide a hanger, comprising: a first connecting member 110, configured to connect a first position of a wall; a second connecting member 120, configured to connect a second position of the wall; and a first hanger beam 130, flexibly connected between the first connecting member 110 and the second connecting member 120, the first hanger beam 130 being rotatable about a connecting line of the first position and the second position to approach or move away from the wall.

[0037] Compared with the traditional large-volume metal hanger 100, the technical scheme of the present application provides a new hanger 100 with small volume, thin thickness and stretching function. The hanger 100 is fixed on the first position of the wall body through the first connecting piece 110, and is fixed on the second position of the wall body through the second connecting piece 120. At the same time, the two ends of the first hanging beam 130 are respectively flexibly connected to the first connecting piece 110 and the second connecting piece 120. In this way, the first hanging beam 130 can rotate around the first position and the second position to move away from the wall body to provide a hanging space for the hook rack 200 used for fixing the display body, or move close to the wall body to make the hook rack 200 tightly abut against the wall body under the pressing of the display body, and be locked and fixed with the hanger 100. The whole hanger 100 has simple structure and low cost, and has good flexibility and high assembly convenience. In addition, after the hook rack 200 and the display body are hung on the hanger 100, the gap between the display body and the wall body is small, the overall appearance is good, and the user experience is high.

[0038] Specifically, the hanger 100 is configured as a combined member including at least the first connecting piece 110, the second connecting piece 120 and the first hanging beam 130. The first connecting piece 110 can be a metal ring-shaped member with large hardness and rigidity to enhance the connection and fastening with the wall body and prolong the service life of the hanger 100. The first connecting piece 110 is provided with a connecting hole in the middle, which can be connected to the first position of the wall body through fasteners such as expansion screws / bolts. The second connecting piece 120 can be a metal ring-shaped member with large hardness and rigidity to enhance the connection and fastening with the wall body and prolong the service life of the hanger 100. The second connecting piece 120 is provided with a connecting hole in the middle, which can be connected to the second position of the wall body through fasteners such as expansion screws / bolts. The first hanging beam 130 can be a steel wire rope, the two ends of which can be connected to the first connecting piece 110 and the second connecting piece 120 respectively by welding. In addition, one end of the first hanging beam 130 can rotate forward and backward around the first position to move away from or close to the wall body, and the other end of the first hanging beam 130 can rotate forward and backward around the second position to move away from or close to the wall body. The middle region of the first hanging beam 130 follows the rotation of the two ends, and the sum of the rotations of the two ends of the first hanging beam 130 constitutes the forward and backward movement track of the first hanging beam 130. In this way, it is convenient for the subsequent hanging of the hook rack 200 with the first hanging beam 130, and the locking and fixing between the hook rack 200, the hanger 100 and the wall body, and the use is convenient and easy to operate.

[0039] In an example, the first connecting piece 110, the second connecting piece 120 and the first hanging beam 130 can be integrally formed to facilitate processing, improve the appearance and overall hardness of the hanger 100, and prolong the service life of the hanger 100. For example, a steel wire with a suitable radial size can be selected, and the first hanging beam 130 with a one-word type in the middle is selected. Then, the two ends are bent once, and the two ends are bent into a circular ring shape to obtain the first connecting piece 110 and the second connecting piece 120. Finally, the circular ring tail end of the first connecting piece 110 is welded to the corresponding circular ring root of the first connecting piece 110, and the circular ring tail end of the second connecting piece 120 is welded to the corresponding circular ring root of the second connecting piece 120 to strengthen the overall structure. The hanger 100 provided in the example has strong appearance, high overall strength, large bearing capacity for the hook rack 200 and the display body, and good wall hanging effect.

[0040] In an example, the second position and the first position can be on the same horizontal straight line. At this time, the first hanging beam 130 can have a uniform radial size, so that when the hook rack 200 is hung on the first hanging beam 130, uniform tension can be generated on both sides of the first hanging beam 130, improving the wall hanging stability and reliability of the display device. Of course, in other embodiments, the second position and the first position can also not be on the same horizontal straight line. At this time, the radial size of the first hanging beam 130 can be a non-uniform size, so that after the hanger 100 is fixed on the wall, the hanging point of the first hanging beam 130 and the hook rack 200 can be at the lowest position, thereby making the bearing force on both sides of the first hanging beam 130 uniform, reducing the risk of the first hanging beam 130 being pulled off, and prolonging the service life of the hanger 100.

[0041] As shown in Figure 1 and Figure 2 In a possible implementation, the first connecting piece 110 includes a first connecting part 111 and a first flexible arm 112 connected flexibly. The first connecting part 111 is connected to the first position, and the first flexible arm 112 is connected to one end of the first hanging beam 130 away from the first connecting part 111.

[0042] In this embodiment, the specific configuration of the first connecting member 110 is optimized. Specifically, the first connecting member 110 is configured as a combined member including at least the first connecting portion 111 and the first flexible arm 112. The first connecting portion 111 can be a hollow circular ring structure configured to cooperate with a fastener such as an expansion screw / bolt to fix the hanging rack 100 at the first position of the wall. The first flexible arm 112 can be a steel wire rope connected to the first connecting portion 111 by welding or one-piece forming, and can rotate around the first connecting portion 111 to provide a larger rotation space for the first hanging beam 130, thereby realizing full-size universality of the hanging rack 100 and promoting standardized production of the hanging rack 100. The first flexible arm 112 can be away from or close to the wall around the first position, to drive the first hanging beam 130 away from the wall and form a hanging space between the wall and the first hanging beam 130, facilitating the hook rack 200 to be hung on the first hanging beam 130. Alternatively, the first flexible arm 112 can drive the first hanging beam 130 to be close to the wall, so that the hook rack 200 hung on the first hanging beam 130 can be tightly abutted against the wall and form a lock with the wall, preventing the hook rack 200 from being detached from the restraint of the first hanging beam 130, and enhancing the hanging fastening and stability of the hook rack 200 and the hanging rack 100, and improving the reliability of the hook rack 200 and the overall structure of the hanging.

[0043] As shown in Figure 1 and Figure 2 In one possible implementation, the second connecting member 120 includes a second connecting portion 121 and a second flexible arm 122 connected in flexibility. The second connecting portion 121 is connected to the second position, and the second flexible arm 122 is connected to the other end of the first hanging beam 130 away from the second connecting portion 121.

[0044] In this embodiment, the specific configuration of the second connecting member 120 is optimized. Specifically, the second connecting member 120 is configured as a combined member including at least the second connecting part 121 and the second flexible arm 122. The second connecting part 121 can be a hollow ring structure for cooperating with a fastener such as an expansion screw / bolt to fix the hanging rack 100 at the second position of the wall. The second flexible arm 122 can be a steel wire rope connected to the second connecting part 121 by welding or one-piece forming, and can rotate around the second connecting part 121 to provide a larger rotation space for the first hanging beam 130, realize the full-size universality of the hanging rack 100, and promote the standardized production of the hanging rack 100. The second flexible arm 122 can be away from or close to the wall to drive the first hanging beam 130 away from the wall and form a hanging space between the wall and the first hanging beam 130, facilitating the hook rack 200 to be hung on the first hanging beam 130; or, the second flexible arm 122 can drive the first hanging beam 130 to be close to the wall, so that the hook rack 200 hung on the first hanging beam 130 can abut against the wall and form a lock with the wall, preventing the hook rack 200 from being separated from the restraint of the first hanging beam 130, strengthening the hanging fastening and stability of the hook rack 200 and the hanging rack 100, and improving the reliability of the hook rack 200 and the overall structure of the hanging.

[0045] As shown in Figure 1 and Figure 2 In a possible implementation, a thermoplastic member 140 is further included, which is sleeved at the connection between the first connecting part 111 and the first flexible arm 112 and / or the connection between the second connecting part 121 and the second flexible arm 122.

[0046] In this embodiment, the specific configuration of the hanging rack 100 is further optimized. Specifically, the hanging rack 100 is configured as a combined member including at least the first connecting member 110, the second connecting member 120, the first hanging beam 130, and the thermoplastic member 140. The thermoplastic member 140 can be a thermoplastic tube with strong heat shrinkage, which can be sleeved at the connection between the first connecting part 111 and the first flexible arm 112 and / or the connection between the second connecting part 121 and the second flexible arm 122 at normal temperature, and then heated to firmly adhere to the ring root position of the first connecting member 110 and the second connecting member 120, realizing the hiding of the connection between the first connecting part 111 and the first flexible arm 112 and / or the connection between the second connecting part 121 and the second flexible arm 122, improving the overall appearance of the hanging rack 100, and improving the overall strength and connection reliability of the hanging rack 100.

[0047] As shown in Figure 2As shown, in one possible implementation, a second hanging beam 150 is further included, which is flexibly connected between the first connecting piece 110 and the second connecting piece 120 and can rotate with the connecting line between the first position and the second position to approach or move away from the wall, and the second hanging beam 150 is located between the first hanging beam 130 and the wall.

[0048] In this embodiment, the specific configuration of the hanging rack 100 is further optimized. Specifically, the hanging rack 100 is configured as a combined component including at least the first connecting piece 110, the second connecting piece 120, the first hanging beam 130, and the second hanging beam 150. The second hanging beam 150 can be a nearly U-shaped steel wire, and its two ends can be connected to the first connecting piece 110 and the second connecting piece 120 respectively by welding or one-piece forming, and located above the first hanging beam 130. At this time, the length of the second hanging beam 150 is greater than the length of the first hanging beam 130, and the distance from the second hanging beam 150 to the first position and the second position is less than the distance from the first hanging beam 130 to the first position and the second position. In this way, the hook rack 200 and the display body that need a smaller stretching distance can be hung through the second hanging beam 150, and the hook rack 200 and the display body that need a larger stretching distance can be hung through the first hanging beam 130, the hanging height of the display body can be adjusted and controlled, and the convenience is higher.

[0049] In an example, the first connecting piece 110, the second connecting piece 120, the first hanging beam 130, and the second hanging beam 150 can be provided in one piece to facilitate processing; at the same time, the appearance and overall hardness of the hanging rack 100 are improved, and the service life of the hanging rack 100 is prolonged. For example, a steel wire with a suitable radial size can be selected, and a first hanging beam 130 with a one-word type in the middle is selected; then the two ends are bent once respectively, and the two bent ends are bent into a circular ring shape to obtain the first connecting piece 110 and the second connecting piece 120; finally, the tail ends of the two circular rings are bent twice to form a nearly U-shaped second hanging beam 150. The appearance of the hanging rack 100 provided in this example is strong, the overall strength is high, the carrying capacity of the hook rack 200 and the display body is large, and the wall hanging effect is good; and the stretching distance of the hanging rack 100 can be controlled through the second hanging beam 150 and the first hanging beam 130, and the application range is wider.

[0050] In addition, as shown in Figure 8 and Figure 9 The application further provides a connecting device, which includes the hook rack 200 and the hanging rack 100 as described above, and the hook rack 200 is hooked on the first hanging beam 130 of the hanging rack 100.

[0051] In the embodiment, the connecting device 10 is configured as a combined member including at least the hook rack 200 and the hanging rack 100. The hook rack 200 can be a common metal hook rack 200 in a nearly inverted U shape, as shown in Figure 8 The hook rack 200 includes a front metal plate, a rear metal plate and a top metal plate. The front metal plate and the rear metal plate are respectively connected to opposite sides of the top metal plate and extend downward. The length of the front metal plate is greater than that of the rear metal plate. The front metal plate is provided with a connecting hole for fixing a display body. When hanging, the first hanging beam 130 is first pulled away from the wall, and then the rear metal plate is inserted between the first hanging beam 130 and the wall. The hook rack 200 is then lowered, and the top metal plate is abutted against the first hanging beam 130. Then, the display body is connected to the connecting hole of the front metal plate. The weight of the display body is used to press the rear metal plate against the front metal plate, so as to lock the first hanging beam 130 in the space formed by the front metal plate, the top metal plate and the rear metal plate, thereby realizing the locking of the hook rack 200 and the hanging rack 100. Alternatively, the hook rack 200 can also be a special hook rack 200 provided by the present application, as shown in Figure 9 The specific structure is described below. The connecting device 10 provided by the embodiment realizes the locking of the hook rack 200 and the hanging rack 100 by using the weight of the display body, and has strong wall hanging stability and reliability. The hanging rack 100 provided by the embodiment has strong universality, and can be used with the common hook rack 200 or the special hook rack 200 provided by the present application, thereby having a wide application range.

[0052] Meanwhile, the specific structure of the hanging rack 100 refers to the above-mentioned embodiments. Since the connecting device 10 adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described here.

[0053] As shown in Figures 3 to 5 In a possible implementation, the hook rack 200 includes a hook body 210 and a locking member 220. The locking member 220 is rotationally connected to the hook body 210 and is provided with a clamping groove 201 on the side facing the hook body 210. When the locking member 220 is abutted against the hook body 210, the clamping groove 201 and the hook body 210 form a containing space for containing the first hanging beam 130.

[0054] In this embodiment, the specific configuration of the hook rack 200 is optimized. Specifically, the hook rack 200 is configured as a combined member including at least a hook body 210 and a locking piece 220. The hook body 210 can be a plate-shaped structure, and a connecting hole is provided at the lower end of the hook body 210. The display body can be connected to the hook rack 200 through the connecting hole. The locking piece 220 can be a wedge-shaped block, and the top end of the wedge-shaped block is a thick block end, which is rotatably connected to the top end of the hook body 210. The bottom end of the wedge-shaped block is a thin sheet end, which is spaced apart from the hook body 210. The clamping groove 201 can be a semicylindrical groove facing the hook body 210. The hook rack 200 has an open state and a locked state. In the open state, the locking piece 220 is arranged at an angle with the hook body 210, and the clamping groove 201 faces downward or left downward / right downward. In the locked state, one side surface of the locking piece 220 abuts against the hook body 210 and forms a lock with the hook body 210, and the other side surface is parallel to the plane on which the hook body 210 is located, so as to abut against the wall surface. In this way, the locking piece 220 can be rotated in a direction away from the hook body 210, so that the clamping groove 201 faces downward or left downward / right downward. At this time, the hook rack 200 is in the open state, and the first hanging beam 130 of the hanging rack 100 can be clamped into the clamping groove 201. Then, the locking piece 220 is rotated in a direction close to the hook body 210, so that the locking piece 220 abuts against the hook body 210, and the lower notch of the clamping groove 201 abuts against the surface of the hook body 210. At this time, the hook rack 200 is in the locked state, and the first hanging beam 130 of the hanging rack 100 can be firmly locked in the accommodation chamber of the hook rack 200, thereby improving the connection fastening. The hook rack 200 provided in this example can be rotated forward and backward, and the connection fastening with the first hanging beam 130 is reliable, and subsequent disassembly and maintenance is convenient.

[0055] As shown in Figures 3 to 7 In one possible implementation, the hook body 210 includes a hooking part 211 and a connecting part 212. One end of the hooking part 211 is protrusively arranged on the connecting part 212 in a first direction Y of the hook body 210, and the other end is spaced apart from the connecting part 212 in a second direction X of the hook body 210 to form a half groove body.

[0056] The locking piece 220 includes an abutting part 221 and two adapter ears 222. The two adapter ears 222 are spaced apart on the abutting part 221 in a third direction Z of the hook body 210 and are rotatably connected to the outside of the hooking part 211. The clamping groove 201 is arranged on one side of the abutting part 221 close to the adapter ears 222 and communicates with the half groove body to form an accommodation space.

[0057] In this embodiment, the specific configuration of the hook body 210 and the locking piece 220 is optimized. Specifically, the hook body 210 is configured as a composite member including at least a hooking part 211 and a connecting part 212. The hooking part 211 can be a hook-shaped ear, and the connecting part 212 can be a nearly rectangular plate. The hooking part 211 is arranged at the top end of the connecting part 212 and forms a hook structure at the top end of the connecting part 212, which is used for hooking the first hanging beam 130 / second hanging beam 150. The hooking part 211 is arranged at the middle region of the top end of the connecting part 212 to reserve a rotating installation space of the locking piece 220 on both sides. Meanwhile, the locking piece 220 is configured as a composite structure including at least an abutting part 221 and two rotating ears 222. The abutting part 221 can be a wedge-shaped block with a thickness change in the first direction Y. The farther away from the rotating fulcrum, the thinner the thickness. A large inclined surface is formed on the side facing the hook body 210 to facilitate the insertion into the first hanging beam 130 / second hanging beam 150. The rotating ear 222 can be a nearly elliptical top with the maximum thickness, which is arranged at the top end of the abutting part 221. The two connecting ears are sleeved on both sides of the hooking part 211 and can rotate around the straight line in the second direction X to move the hook body 210 away from or close to the wall, thereby realizing the forward and backward rotation of the hook rack 200. The hook rack 200 provided in this example has a compact layout and is not easy to break at the connection with the first hanging beam 130, and has a stable and reliable structure.

[0058] In an example, the hooking part 211 is provided with a rotating hole extending along the third direction Z, and the rotating ear 222 is provided with a rotating hole extending along the third direction Z, and the rotating hole is arranged opposite to the rotating hole. The hook rack 200 further includes a rotating shaft 230, which is sequentially inserted into the rotating hole, the rotating hole and the other rotating hole to realize the rotating connection of the two rotating ears 222 and the hooking part 211. The rotating mode of the hook body 210 and the locking piece 220 provided in this example is simple and reliable, and has good rotating effect.

[0059] It should be explained that the first direction Y can be the length direction of the connecting part 212, the second direction X can be the thickness direction of the connecting part 212, and the third direction Z can be the width direction of the connecting part 212.

[0060] As Figures 3 to 6As shown, in one possible embodiment, the abutment portion 221 is provided with a guide slope 202 facing the connecting portion 212, and the guide slope 202 is located on the side of the slot 201 away from the adapter ear 222. This arrangement allows the thickness of the abutment portion 221 to vary unevenly in the third direction Z, thereby reducing material waste at the tail end and lowering costs; it also strengthens the overall strength of the top stress point and extends the service life of the locking member 220. Furthermore, the guide slope 202 reduces the difficulty of inserting the first hook beam 130, making insertion smoother and with less resistance, thus improving the ease of assembly between the hanger 100 and the hook frame 200.

[0061] like Figures 3 to 6 As shown, in one possible implementation, the adapter ear 222 is provided with a limiting inclined surface 203, which corresponds to the connecting part 212. This arrangement can limit the rotation angle of the locking member 220, effectively control the opening angle of the locking member 220, and improve the ease of attaching the first connecting beam 130.

[0062] Furthermore, this application also provides a display device, characterized in that it includes a display body (not shown in the figure) and a connecting device 10 as described above, wherein the display body is hung on the wall via a hook 200 of the connecting device 10.
