[0039] The terms "first", "second", and the like in the description and claims of the present application and the above drawings are used to distinguish different objects, and are not used to describe a particular order. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0040] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase "in an embodiment" appears multiple times in the specification does not necessarily refer to the same embodiment, nor is it necessary that all of the embodiments include the same features or functions. It will be explicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] Please refer to Figure 1 , Figure 1 is the overall structure diagram of the pylon in some embodiments of the present application. As Figure 1As shown, the hanger 100 comprises a wall plate 110, a hanging piece 150 and a movable assembly 180, wherein the hanging piece 150 is used to be fixedly connected with the back of a display device (not shown), the movable assembly 180 comprises a support arm 120, a panel structure 130 and a connecting piece 141 and a connecting plate 140, one end of the support arm 120 is pivotally connected with the wall plate 110, the other end of the support arm 120 is pivotally connected with one side of the connecting plate 140, and the other side of the connecting plate 140 is connected with the panel structure 130 through the connecting piece 141. Specifically, the panel structure 130 comprises upper and lower transversely parallel cross arms 131a and 131b, and a connecting side arm 132 longitudinally arranged between the upper and lower cross arms 131a and 131b, the plane of the connecting side arm 132 is perpendicular to the extension direction of the upper and lower cross arms 131a and 131b, the connecting side arm 132 is provided with a first strip-shaped connecting hole H1 and a first connecting hole H2 penetrating through the connecting side arm 132, the first strip-shaped connecting hole H1 is transversely arranged above the first connecting hole H2, and the other side of the connecting plate 140 is connected with the first strip-shaped connecting hole H1 and the first connecting hole H2 through two connecting pieces 141 respectively, the hanging piece 150 is connected with the upper cross arm 131a and locked with the lower cross arm 131b, and the panel structure 130 has different pitch angles relative to the wall plate 110 when the connecting piece 141 is located at different positions of the first strip-shaped connecting hole H1.

[0042] Please continue to refer to Figure 1 , for the convenience of description, it is defined Figure 1 The front-to-back direction of the hanger 100 shown is the Y-axis direction, that is, the thickness direction, the left-to-right direction is the X-axis direction, that is, the length direction, and the height direction is the Z-axis direction. The "upper", "lower", "left" and "right" and other orientation words mentioned in the description of the hanger 100 are described according to the orientation shown in the drawings Figure 1 The orientation shown is described as "up" towards the positive direction of the Z-axis, "down" towards the negative direction of the Z-axis, "left" towards the negative direction of the X-axis, "right" towards the positive direction of the X-axis, "back" towards the negative direction of the Y-axis, and "front" towards the positive direction of the Y-axis, which does not form a limitation on the hanger 100 in the actual application scenario.

[0043] Therefore, when the pitch angle of the display device needs to be adjusted, the connecting piece 141 is loosened, and due to the transverse arrangement and length allowance of the first strip-shaped connecting hole H1, the connection position of the connecting plate 140 and the panel structure 130 can be changed by manually applying an external force. After adjusting to the desired pitch angle, the connecting piece 141 is tightened again to fix the panel structure 130 at the corresponding position. Specifically, when the connecting piece 141 is located at the first strip-shaped connecting hole H1, the pitch angle of the panel structure 130 relative to the wall plate 110 is 0°; when the connecting piece 141 is located at the first connecting hole H2, the pitch angle of the panel structure 130 relative to the wall plate 110 is 90°; and when the connecting piece 141 is located at the second strip-shaped connecting hole H2, the pitch angle of the panel structure 130 relative to the wall plate 110 is 180°. Figure 1For reference, after loosening the connecting piece 141, because the first bar-shaped connecting hole H1 is transversely arranged (i.e., along the Y-axis direction) and has a length allowance, an external force is manually applied to rotate the panel structure 130 relative to the connecting sheet 140 around the axis along which the X-axis is located (i.e., in the direction of the illustrated arc-shaped arrow), in this rotation process, the included angle of the panel structure 130 relative to the wall plate 110 changes, and this change in the included angle is an embodiment of adjustment of the pitch and tilt angle, and when the ideal pitch and tilt angle is reached, the connecting piece 141 is tightened to fix the panel structure 130.

[0044] In addition, unlike the conventional method of arranging the pitch and tilt adjustment part in the middle, the pitch and tilt angle adjustment method of this design is at the two edges, and in the actual adjustment process, because of the edge position, the operation space is more sufficient, and the user can more easily apply force to adjust the angle.

[0045] The display device can include a television, a display, an electronic whiteboard, and the like.

[0046] In some embodiments, the adjustment range of the pitch angle can be [0, +3°], wherein the adjustment range of the pitch angle can be set according to actual conditions, which is not specifically limited here.

[0047] Through the above hanging rack 100, the angle of the display device can be adjusted to the most comfortable viewing angle and the best display angle in different scenes, and through the pivoting link of the support arm 120, the wall plate 110, and the connecting sheet 140, and the connection and locking of the hanging piece 150 and the upper cross arm 131a and the lower cross arm 131b of the panel structure 130, the hanging rack 100 remains stable after the angle is adjusted and can ensure normal installation of the display device even under external force interference.

[0048] In addition, the structure of the hanging rack 100 of the utility model is relatively simple, easy to understand and assemble, can save labor and time cost during installation, and is conducive to post-maintenance.

[0049] In some embodiments, the first strip-shaped connecting hole H1 is an arc-shaped hole centered on the first connecting hole H2. Thus, the arc-shaped first strip-shaped connecting hole H1 can more accurately control the change in the pitch angle of the panel structure 130 relative to the wallboard 110 during movement, and can make the movement trajectory of the connecting piece 140 more consistent with the circular motion centered on the first connecting hole H2, thereby achieving smoother angle adjustment. In terms of structural stability, since the connecting piece 140 moves in the arc-shaped hole, the direction of the force is always around the center of the first connecting hole H2, so that the stress on the connecting part between the support arm 120, the connecting piece 140 and the connecting side arm 132 is more uniform, which can better disperse the stress generated by angle adjustment and reduce local stress concentration, thereby further enhancing the structural stability of the hanging rack 100 at different pitch angles, reducing the risk of damage to components due to uneven stress, and prolonging the service life of the hanging rack.

[0050] In some embodiments, the arc-shaped first strip-shaped connecting hole H1 makes the angle adjustment operation more smooth, and when adjusting the pitch angle of the display device, a linear and coherent adjustment feel can be felt, thereby improving the convenience and comfort of operation and further improving the user experience.

[0051] In some embodiments, the first strip-shaped connecting hole H1 can also be a straight-line type first strip-shaped connecting hole centered on the first connecting hole H2. During adjustment, the connecting piece 141 can move linearly in the straight-line type first strip-shaped connecting hole, thereby controlling the change in the pitch angle of the panel structure 130 relative to the wallboard 110.

[0052] In some embodiments, the first strip-shaped connecting hole H1 can also include a polygonal hole, a trapezoidal hole and a combined shape hole centered on the first connecting hole H2, and the shape of the first strip-shaped connecting hole H1 can be set according to actual conditions, which is not specifically limited here.

[0053] In some embodiments, referring to Figure 2 , the connecting piece 140 includes a main body part 140a and a U-shaped connecting part 140b. The main body part 140a is in a long strip plate structure, and two second connecting holes H3 are provided on the main body part 140a and penetrate the main body part 140a. The two second connecting holes H3 are respectively arranged corresponding to the first strip-shaped connecting hole H1 and the first connecting hole H2 of the connecting side arm 132. The U-shaped connecting part 140b is arranged perpendicularly to the side of the main body part 140a away from the connecting side arm 132, the opening of the U-shaped connecting part 140b faces the wallboard 110, and the U-shaped connecting part 140b is arranged between the two second connecting holes H3 of the main body part 140a.

[0054] The long strip-shaped structure of the main body 140a and the connection of the connecting side arm 132 provide a large contact area, and the two second connecting holes H3 are matched with the first strip-shaped connecting hole H1 and the first connecting hole H2 respectively, and after the connecting piece 141 is fixed, a stable connection relationship is formed, which effectively prevents the connecting piece 140 from being displaced or loosened during adjustment, and ensures the structural stability of the hanging rack 100; at the same time, the structure of the U-shaped connecting part 140b further enhances the connection strength between the connecting piece 140 and the supporting arm 120, and the two side edges of the U-shaped connecting part 140b can better wrap the end of the supporting arm 120, which can ensure the stable connection between the connecting piece 140 and the supporting arm 120, and avoid connection failure due to excessive stress.

[0055] Please continue to refer to Figure 2 In one embodiment, the two second connecting holes H3 on the main body 140a of the connecting piece 140 are non-circular holes, and the connecting piece 141 is provided with a matching non-circular section 141a. When the connecting piece 141 passes through the non-circular connecting hole, the non-circular connecting hole and the non-circular section 141a of the connecting piece 141 are matched, which limits the rotation of the connecting piece 141 relative to the connecting piece 140, forming a rotation-stopping structure.

[0056] In some embodiments, the two second connecting holes H3 on the main body 140a of the connecting piece 140 can include square holes, and the connecting piece 141 is provided with a matching square section, wherein the inner diameter of the inscribed circle of the square section on the connecting piece 141 is greater than the outer diameter of the thread of the threaded rod on the connecting piece 141.

[0057] Therefore, the square hole and the square section are matched with each other, which can effectively prevent the connecting piece from rotating in the connecting hole, ensure that the connecting piece 140 and the connecting piece 141 always remain stable connection during the daily use of the hanging rack 100 and the adjustment of the pitch angle of the panel structure 130, avoid the loosening caused by the rotation of the connecting piece 141, and ensure the stable installation of the display device; at the same time, the matching of the square hole and the square section makes the positioning direction clear during installation, and the installer does not need to repeatedly adjust the angle to align the connecting hole, which improves the installation efficiency and reduces the installation error.

[0058] In some embodiments, the two second connecting holes H3 on the main body 140a of the connecting piece 140 can include polygonal holes, and the connecting piece 141 is provided with a matching polygonal section, etc. The matching shape of the rotation-stopping structure can be set according to actual conditions, which is not specifically limited here.

[0059] In some embodiments, please continue to refer to Figure 1The support arm 120 comprises a rear support arm 121 and a front support arm 122, one end of the rear support arm 121 is hinged to the wall plate 110, one end of the front support arm 122 is hinged to the other end of the rear support arm 121, and the other end of the front support arm 122 is pivotally connected to the connecting plate 140.

[0060] Therefore, the hanger 100 can flexibly adjust the position and angle of the display device, realize multi-angle and multi-dimensional adjustment of the display device, and the user can accurately adjust the position and angle of the display device according to actual use requirements to achieve the best viewing effect.

[0061] Specifically, since the rear support arm 121 is hinged to the wall plate 110 and the front support arm 122 is hinged to the rear support arm 121, when the front and rear support arms rotate, the connecting plate 140 and the panel structure 130 connected thereto can be displaced in the X-axis direction, thereby changing the orientation of the display surface of the display device; at the same time, the connection of the support arm 120 can make the display device move forward and backward in the Y-axis direction, thereby realizing the telescopic effect.

[0062] The front support arm 122 is pivotally connected to the connecting plate 140, and the connecting plate 140 is connected to the panel structure 130 with the first strip-shaped connecting hole H1 and the first connecting hole H2 through the connecting piece 141. By loosening the connecting piece 141 and using the characteristics of the first strip-shaped connecting hole H1, the display device can be rotated around the X-axis to adjust the pitch angle; at the same time, the hinging of the rear support arm 121 to the wall plate 110, in combination with the hinging of the front support arm 122 to the rear support arm 121, can also make the display device rotate left and right around the Z-axis, change the orientation of the display surface, and adapt to different viewing position requirements.

[0063] Wherein, by setting the multi-section support arm design of the rear support arm 121 and the front support arm 122 effectively disperses the load, so that the gravity of the display device and the external force received during use is transmitted to the rear support arm 121 through the front support arm 122, and then dispersed to the wall plate 110 by the rear support arm 121, avoiding excessive stress on a single point, so that the hanging rack 100 can still maintain stability when bearing a larger weight display device; at the same time, when adjusting the angle, the rear support arm 121 is hinged with the wall plate 110, and the pivot shaft at the hinge extends in the vertical direction, which enables the rear support arm 121 to rotate left and right around the vertical pivot shaft (i.e. rotate around the Z axis), thereby changing the orientation of the front support arm 122 and the display surface connected thereto. At the same time, the front support arm 122 and the rear support arm 121 are also hinged, and the pivot shaft at the hinge point also extends in the vertical direction, further enhancing the flexibility of the hanging rack 100 when adjusting; and the front support arm 122 is pivotally connected with the connecting piece 140, and the pivot shaft also extends in the vertical direction, which not only enables the front support arm 122 to perform front and rear extension movement, but also cooperates with other hinge points to automatically adapt to the stress generated due to the change in angle when adjusting the pitch angle of the display device. This multi-pivot point design with pivot shafts extending in the vertical direction further enhances the stability of the structure, reduces the risk of component damage due to uneven stress, and ensures reliable operation of the hanging rack 100 under various angle adjustments and load conditions.

[0064] In some embodiments, referring to Figure 2 , the two opposite sides are transversely arranged and each is provided with a third connecting hole H4 extending along the height direction of the hanging rack, the front support arm 122 is embedded in the U-shaped connecting part 140b, and a first screw passes through the third connecting hole H4 to pivotally connect the front support arm 122 with the U-shaped connecting part 140b.

[0065] Wherein, the two sides of the U-shaped connecting part 140b refer to the two opposite sides of the opening direction of the U-shaped structure, that is, the two opposite parallel sides extending from the vertical direction of the main body of the U-shaped connecting part 140b, which are symmetrically distributed on both sides of the U-shaped connecting part 140b, and each side is provided with a third connecting hole H4 extending through it, which can be used to pass through connecting members such as screws to achieve stable connection with other components and enhance the stability of the overall structure.

[0066] Therefore, when the hanger 100 bears the gravity of the display device and various forces generated by the angle adjustment, the connection structure can effectively disperse the stress, avoid the connection loosening or damage caused by the excessive force on a single point, ensure that the hanger always maintains a stable structure state during long-term use, and provide reliable support for the display device; at the same time, the front support arm 122 can be flexibly rotated according to the angle adjustment requirement of the hanger 100, ensuring the stability and accuracy during the rotation.

[0067] In some embodiments, the hanger 100 includes two support arms 120, two connecting plates 140, and two connecting side arms 132; the two connecting side arms 132 are respectively connected to opposite sides of the panel structure 130; and the support arms 120, the connecting plates 140, and the connecting side arms 132 are in one-to-one correspondence. Among them, the front support arms 122 of the two support arms 120 are respectively embedded in the U-shaped connecting portions 140b of the two connecting plates 140 and are pivotally connected; and the main body portions 140a of the two connecting plates 140 are respectively connected to the two connecting side arms 132.

[0068] Therefore, the gravity of the display device and various external forces borne during use can be uniformly dispersed by the double-sided stacked support structure, effectively avoiding the structural inclination or deformation caused by unilateral force, ensuring the stability of the overall structure of the hanger 100, and enhancing the carrying capacity of the hanger 100.

[0069] Further, the hanger 100 of the utility model adopts a single-wallboard double-support-arm structure, that is, a double-sided symmetrical support system composed of a wallboard 110, a rear support arm 121, and a front support arm 122. In actual use, the gravity of the display device and various external forces borne during daily operation can be uniformly dispersed through the double-sided symmetrical support structure, which effectively avoids the structural inclination or deformation caused by unilateral force; at the same time, the double-sided symmetrical structure of the single-wallboard double-support-arm of the hanger 100 enables the two support arms to share the force, ensuring the stability of the overall structure of the hanger 100 and greatly enhancing the carrying capacity of the hanger 100, so that it can reliably support various display devices.

[0070] In some embodiments, please refer to Figure 3 , Figure 3 to Figure 1The exploded view of the support arm of the shown hanger. The specific installation process of the support arm 120 is as follows: place the gasket F2 in the appropriate position, then put the rear support arm 121 on the first connecting screw L2, and then put the gasket F2 and the first fixing piece F1 on the other end of the first connecting screw L2, tighten the first fixing piece F1 with tools, and through the threaded connection between the first fixing piece F1 and the screw, the rear support arm 121 is tightly connected with other components to ensure the stability and reliability of the connection; then put the front support arm 122 on the first connecting screw L2, and then put the gasket F2 and the first fixing piece F1 on the other end of the first connecting screw L2 and tighten them to realize the stable connection between the front support arm 122 and the connecting piece 140; finally, pass the long connecting screw L3 through the corresponding hole positions of the rear support arm 121 and the front support arm 122 that need to be connected, and then put the gasket F2 and the first fixing piece F1 on both ends of the long connecting screw L3 and tighten them to make the rear support arm 121 and the front support arm 122 firmly connected into a whole, which can jointly bear the load and external force to ensure that the support arm system can stably support the hanger and the display device.

[0071] In some embodiments, please refer to Figure 4 , Figure 4 for Figure 1 The structure diagram of the hanger of the shown hanger. The hanger includes two hangers, which are connected to the back of the display device. Each of the hangers 150 includes a hanging bar 151, a hook 152, and an adjusting screw L1, the hanging bar 151 and the hook 152 are connected and have a free degree of activity in the height direction, the hook 152 is connected with the upper cross arm 131a of the panel structure 130, and the adjusting screw L1 is threadedly connected with the hanging bar 151 and abuts against the upper cross arm 131a.

[0072] Wherein, the hanging bar 151 and the hook 152 have a free degree of activity in the height direction, by rotating the adjusting screw L1, using its threaded connection with the hanging bar 151, and further pushing the hanging bar 151 to adjust the horizontal inclination angle of the display device in the height direction. Wherein, the horizontal inclination angle refers to the included angle between the plane where the display device is located and the absolute horizontal reference plane, when the included angle is 0°, the display device is in a completely horizontal state; if the included angle is not 0°, it indicates that the display device is inclined relative to the horizontal direction. By adjusting the hanging bar 151 in the height direction, the height of different parts of the display device can be changed, thereby changing the size of the included angle, so that the display device approaches or reaches the completely horizontal state.

[0073] The two hangers 150 are provided with the above structure, and factors such as flatness of the wall surface and installation accuracy of the wall plate 110 can cause the display device to have insufficient levelness. Through the above structure, the installer does not need to make large-scale adjustment to the entire hanger or the wall surface, and can quickly correct the horizontal inclination angle of the display device by simply adjusting the screw rod L1, which is beneficial to shorten the installation time and improve the work efficiency. Specifically, when the display device is found to have deviation in the horizontal direction, the installer only needs to simply rotate the adjusting screw rod L1 to make the hanging strip 151 have accurate displacement in the height direction relative to the hook 152; for example, if the left side of the display device is too high, the installer can operate the adjusting screw rod L1 on the left hanger 150 to make it push the hanging strip 151 to descend and reduce the height of the left side, or can operate the adjusting screw rod L1 on the right hanger 150 to make it drive the hanging strip 151 to ascend and increase the height of the right side; if the right side is too high, the installer can operate the adjusting screw rod L1 on the right hanger 150 to reduce the height of the right side, or can operate the adjusting screw rod L1 on the left hanger 150 to make the left hanging strip 151 ascend and increase the height of the left side, so as to quickly adjust the horizontal inclination angle of the display device.

[0074] In some embodiments, the hanging strip 151 comprises a movable plate 151a and two movable side plates 151b connected to both ends of the movable plate 151a, the movable plate 151a and the two movable side plates 151b form a clamping space, the hook 152 comprises a connecting plate 152a and two connecting side plates 152b connected to both ends of the connecting plate 152a, the size of the hook 152 is smaller than that of the hanging strip 151 and is accommodated in the clamping space of the hanging strip 151, wherein the movable side plate 151b is provided with a plurality of fourth connection holes H5 penetrating therethrough, and the connecting side plate 152b is provided with a second strip-shaped connection hole H6 extending in the height direction corresponding to the fourth connection hole H5 of the movable side plate 151b, when the adjusting screw rod L1 is adjusted, the hanging strip 151 moves relative to the hook 152 in the height direction through the second strip-shaped connection hole H6, and the panel structure 130 has different inclination angles in the horizontal direction.

[0075] The fourth connection hole H5 is arranged on the movable side plate 151b of the hanging strip 151, and the second strip-shaped connection hole H6 extending in the height direction is arranged on the connecting side plate 152b of the hook 152, and the two are matched with each other.

[0076] When the adjusting screw L1 is rotated to move the hanging strip 151 relative to the hook 152 in the height direction, the relative position of the hanging strip 151 and the hook 152 can be adjusted due to the length allowance of the second strip-shaped connecting hole H6 in the height direction, the horizontal inclination angle of the display device is changed, and the horizontal demand of the user for the horizontal inclination angle of the display device is met; at the same time, the hook 152 is accommodated in the clamping space of the hanging strip 151, and is connected with the fourth connecting hole H5 through the cooperation of the second strip-shaped connecting hole H6 and the fourth connecting hole H5. This design not only realizes the adjustment of the horizontal inclination angle, but also ensures the stability of the connection between the hanging strip 151 and the hook 152. When the display device is subjected to external vibration or other external force, the connection structure of the hanging strip 151 and the hook 152 can effectively disperse stress, prevent the connection part from loosening due to uneven stress, ensure that the display device always maintains a stable horizontal inclination angle during use, avoid angle deviation caused by loose connection, and provide a strong guarantee for long-term stable operation of the display device.

[0077] In some embodiments, please refer to Figure 4 , one end of the hanging strip 151 is provided with a first fixed plate 153 which is vertically arranged with the hanging strip 151, the first fixed plate 153 is provided with a fifth connecting hole H7 which is penetrated, and the adjusting screw L1 penetrates the fifth connecting hole H7 of the first fixed plate 153 and abuts against the upper horizontal arm 131a.

[0078] Among them, the fifth connecting hole H7 on the first fixed plate 153 provides a precise positioning and mounting position for the adjusting screw L1. Thus, the adjusting screw L1 can be easily penetrated through the fifth connecting hole H7 and directly abut against the upper horizontal arm 131a, reducing the installation difficulty of the adjusting screw L1; at the same time, the first fixed plate 153 enhances the connection stability between the adjusting screw L1 and the hanging strip 151. When the adjusting screw L1 exerts a force on the hanging strip 151 during rotation, the first fixed plate 153 can effectively disperse the force, avoiding deformation or damage of the hanging strip 151 due to excessive local stress.

[0079] In addition, by adjusting the position of the adjusting screw L1 in the fifth connecting hole H7 and the abutting mode of the adjusting screw L1 and the upper horizontal arm 131a, the hanging rack can flexibly adapt to the differences of the upper horizontal arm 131a in height, position and the like, and meet various installation requirements.

[0080] Among them, one end of the hook 152 is provided with a second fixed plate 154 which is vertically arranged with the hook 152, the second fixed plate 154 is provided with a sixth connecting hole H8 which is penetrated, and the hanging part 150 further includes a second screw L4 which is threadedly connected with the sixth connecting hole H8 and abuts against the lower horizontal arm 131b.

[0081] Thus, the hanging strip 151 abuts against the upper cross arm 131a through the adjusting screw L1, and the hook 152 abuts against the lower cross arm 131b through the second screw L4, forming a double locking structure, so that the connection between the hanging piece 150 and the panel structure 130 is more stable, and can effectively resist the shaking and displacement of the display device due to external forces such as vibration and collision during use; at the same time, when the display device is subjected to external force, the adjusting screw L1 and the second screw L4 can jointly bear the force, and disperse the force to the upper cross arm 131a and the lower cross arm 131b, avoiding the case that a single point is subjected to excessive force, which helps to prolong the service life of the components of the hanging rack 100, reduce the risk of component damage caused by local force concentration, and improve the reliability and durability of the entire hanging rack 100.

[0082] In some embodiments, please refer to Figure 5 , Figure 5 for Figure 1 the structure diagram of the folded state of the hanging rack structure. The hanging rack 100 further comprises an anti-rebound structure 160 connected between the panel structure 130 and the wall plate 110 when the hanging rack 100 is folded.

[0083] Among them, the anti-rebound structure 160 can effectively prevent the rebound phenomenon of the panel structure 130, for example, when the user folds the hanging rack 100, the hanging rack 100 is retracted, and when the external force disappears, the panel structure 130 has a tendency to automatically recover to the original shape or position due to inertia, and the anti-rebound structure 160 can effectively inhibit the rebound tendency of the panel structure 130, ensure that the panel structure 130 remains in the desired position or shape, and improve the stability and reliability of the entire structure; at the same time, the anti-rebound structure 160 helps to maintain the stability of the hanging rack 100 in the folded state, ensures that the hanging rack 100 still maintains a stable state after being folded, prevents it from being accidentally unfolded due to external interference, and prolongs the service life of the hanging rack 100.

[0084] In some embodiments, please refer to Figure 6 , Figure 6 for Figure 5The structure diagram of the anti-rebound structure in the folded state of the shown hanging rack structure. The anti-rebound structure 160 comprises a bead clamping assembly 163, which comprises a clamping piece 161 arranged on one side of the panel structure 130 facing the wall plate 110 and a bead piece 162 arranged on one side of the wall plate 110 facing the panel structure 130. When the hanging rack 100 is folded, the clamping piece 161 is close to the bead piece 162, the bead 162a is pressed and embedded in the clamping groove 161a of the clamping piece 161, and the panel structure 130 and the wall plate 110 are connected through the bead clamping assembly 163. When the hanging rack 100 is unfolded, the bead 162a is pressed and shrunk out of the clamping groove 161a, and the panel structure 130 and the wall plate 110 are separated.

[0085] Therefore, when the hanging rack 100 is folded, only the panel structure 130 needs to be close to the wall plate 110, and the bead 162a will be pressed and automatically embedded in the clamping groove 161a when it contacts the clamping piece 161, thereby realizing the folding locking of the hanging rack 100, which is simple and convenient to operate. When the hanging rack 100 is unfolded, the bead 162a is pressed and shrunk out of the clamping groove 161a, and the panel structure 130 and the wall plate 110 can be separated, which improves the user's operation efficiency of the hanging rack 100 and reduces the operation time and energy cost.

[0086] In addition, after the bead 162a is embedded in the clamping groove 161a, a tight fit can be formed to provide strong locking force and effectively prevent the hanging rack 100 from rebounding accidentally due to external force vibration, collision and other factors in the folded state.

[0087] The mounting process of the bead clamping assembly 163 is as follows: the clamping piece 161 is provided with two ninth connecting holes H12, the upper horizontal arm 131a is also provided with a first mounting hole H14 corresponding to the ninth connecting holes H12, and a second connecting screw L5 passes through the ninth connecting holes H12 of the clamping piece 161 and the first mounting hole H14 of the upper horizontal arm 131a, respectively, so as to realize the fixed connection of the clamping piece 161 and the upper horizontal arm 131a through the second fixing piece F3, wherein the connection between the clamping piece 161 and the upper horizontal arm 131a is provided with two gaskets F2; the bead piece 162 is provided with two tenth connecting holes H13, and the wall plate 110 is also provided with a second mounting hole H15 corresponding to the tenth connecting holes H13 on the side facing the panel structure 130, and a third connecting screw L6 passes through the tenth connecting holes H13 of the bead piece 162 and the second mounting hole H15 of the wall plate 110, respectively, so as to realize the fixed connection of the bead piece 162 and the wall plate 110.

[0088] In some embodiments, the anti-rebound structure 160 can further include a magnet structure, for example, a male magnet is installed on one side of the panel structure 130 facing the wall plate 110 and a female magnet is installed on one side of the wall plate 110 facing the panel structure 130, when the hanging rack 100 is retracted, the magnets attract each other, thereby achieving the retraction function and preventing the rebound phenomenon. Among them, the structure of the anti-rebound structure 160 can be set according to the actual situation, which is not limited here.

[0089] In some embodiments, please continue to refer to Figure 6 , the panel structure 130 is provided with an extension plate 133, the extension plate 133 is parallel to the connecting side arm 132, and the buckle piece 161 is arranged on one side of the extension plate 133 facing the wall plate 110.

[0090] Therefore, the extension plate 133 provides an additional mounting position for the buckle piece 161, when the layout of other components on the panel structure 130 is relatively compact, the extension plate 133 can utilize the peripheral space of the panel structure 130, so that the mounting position of each component is more reasonable, and the entire hanging rack 100 is compact and orderly.

[0091] In some embodiments, one end of the extension plate 133 is fixedly connected with the upper horizontal arm 131a, and the other end of the extension plate 133 is fixedly connected with the lower horizontal arm 131b, and the buckle piece 161 is arranged on one side of the extension plate 133 facing the wall plate 110.

[0092] Among them, one end of the extension plate 133 is fixedly connected with the upper horizontal arm 131a, and the other end is fixedly connected with the lower horizontal arm 131b, so that the upper and lower parts of the panel structure 130 are more closely connected, and the integrity of the entire panel structure 130 is enhanced. When the hanging rack 100 bears the weight of the display device or is subjected to external force impact, the extension plate 133 can effectively disperse stress, avoid relative displacement or deformation of the upper and lower horizontal arms, and improve the carrying capacity and anti-deformation ability of the hanging rack 100.

[0093] In some embodiments, please refer to Figure 7 , Figure 7 As shown in the structural diagram of the wall plate of the hanging rack. Figure 1 The wall plate 110 includes horizontally parallel upper and lower horizontal plates 110a and 110b, and the upper and lower horizontal plates 110a and 110b each include a plurality of third strip-shaped connecting holes H9, wherein the third strip-shaped connecting holes H9 of the upper and lower horizontal plates 110a and 110b are respectively corresponding and spaced.

[0094] When the size and weight of the display device are different, or the specific situation of the installation wall surface is different, the installer can change the installation position of the support arm 120 or the hanging piece 150 by selecting the third strip-shaped connecting hole H9 at different positions, so as to achieve the best installation effect. The interval between the third strip-shaped connecting holes H9 can accurately adapt to the position and spacing of the column in the house according to the standard of the structure and size specification of the house building, so that when installing, the nails can be accurately punched into the column to provide stable support for the hanging rack 100, ensure that the hanging rack can safely bear the weight of the display device, and greatly improve the stability and reliability of the installation of the hanging rack 100.

[0095] In some embodiments, please continue to refer to Figure 7 , the wall plate 110 further comprises a side plate 111 longitudinally and parallelly arranged between the upper horizontal plate 110a and the lower horizontal plate 110b, and the wall plate 110 further comprises a connecting assembly 112, one end of the rear support arm 121 is connected with the connecting assembly 112, wherein the connecting assembly 112 comprises an end connecting plate 112a and a positioning plate 112b, the end connecting plate 112a is arranged at the connection between the side plate 111 and the upper horizontal plate 110a and the lower horizontal plate 110b and is in the shape of a long strip plate, the positioning plate 112b is arranged on the side plate 111 and is perpendicular to the side plate 111, the positioning plate 112b is parallel to and one-to-one corresponding to the end connecting plate 112a, and the seventh connecting hole H10 is arranged on the positioning plate 112b, and the eighth connecting hole H11 is arranged on the end connecting plate 112a, and one end of the rear support arm 121 is located between the end connecting plate 112a and the positioning plate 112b and is connected by a third screw rod.

[0096] Therefore, through the arrangement of the connecting assembly 112, when the hanging rack 100 is installed, only the one end of the rear support arm 121 needs to be accurately placed between the end connecting plate 112a and the positioning plate 112b, and then the third screw rod is used to pass through the corresponding seventh connecting hole H10 and eighth connecting hole H11 for fixation, so as to improve the installation efficiency; at the same time, the parallel and one-to-one corresponding arrangement of the end connecting plate 112a and the positioning plate 112b, and the accurate positioning of the seventh connecting hole H10 and the eighth connecting hole H11 on the two can ensure the accuracy of the installation position of the rear support arm 121, and ensure the installation of the panel structure 130 and the normal operation of the whole hanging rack 100.

[0097] In some embodiments, please refer to Figure 8 , Figure 8 To Figure 1The front view of the hanging rack structure in a folded state. The middle region of the wall plate 110 is provided with a plurality of avoidance structures 170 corresponding to the avoidance of a plurality of sockets. Thus, by providing the avoidance structures 170, the hanging rack 100 does not need to avoid the area where the sockets are located for installation, fully utilizes the wall space, does not need to adjust the position of the hanging rack 100 to avoid the sockets, or make complex modifications to the wall, greatly simplifies the installation process, reduces the installation difficulty, and improves the installation efficiency.

[0098] Thus, the hanging rack 100 of the utility model can evenly disperse the gravity of the display device and various external forces borne during use through the use of the double-sided symmetrical structure of the single-wall-plate double-support-arm, effectively avoids the problem of structural inclination or deformation caused by unilateral force, greatly ensures the stability of the overall structure, and significantly enhances the carrying capacity.

[0099] In addition, the hanging rack 100 of the utility model can realize adjustment in at least the following four dimensions in terms of angle adjustment:

[0100] First, in the Y-axis direction (i.e. the thickness direction), the hanging rack 100 can realize telescopic adjustment: the front support arm 122 is pivotally connected with the connecting piece 140, and the pivot shaft extends in the vertical direction, so that the front support arm 122 can move forward and backward in the Y-axis direction, and when it is necessary to adjust the distance between the display device and the wall, the front support arm 122 can be moved along the Y-axis direction flexibly through the coordinated operation of the related components, driving the display device to move closer to or away from the wall, and providing a more suitable viewing distance for the user.

[0101] Second, the hanging rack 100 can be adjusted in the pitch inclination angle, i.e. rotated around the X-axis: the front support arm 122 is pivotally connected with the connecting piece 140, the connecting piece 140 is connected with the panel structure 130 through the connecting piece 141, the panel structure 130 is provided with a first strip-shaped connecting hole H1 and a first connecting hole H2, when the connecting piece 141 is loosened, the moving allowance provided by the first strip-shaped connecting hole H1 is used to manually apply an external force to change the connection position of the connecting piece 140 and the panel structure 130, so that the panel structure 130 is rotated around the X-axis, and the adjustment of the pitch inclination angle of the display device is realized, so that the user can obtain a more comfortable viewing experience by adjusting the pitch inclination angle of the display device.

[0102] Third, the hanging rack 100 can change the orientation of the display surface of the display device: the rear support arm 121 is hinged with the wall plate 110, and the front support arm 122 is also hinged with the rear support arm 121, and the pivot shafts of the two hinge points both extend in the vertical direction, so that the rear support arm 121 can rotate left and right around the vertical pivot shaft, and then drive the front support arm 122 and the display device connected therewith to change the orientation on the horizontal plane.

[0103] Fourth, the hanger 100 has the function of adjusting the horizontal inclination angle of the display device: the hanging bar 151 and the hook 152 have the freedom in the height direction, by rotating the adjusting screw L1, using the threaded connection with the hanging bar 151, the hanging bar 151 can be accurately adjusted in the height direction relative to the hook 152, in the actual installation process, due to the wall flatness, wallboard 110 installation precision and other factors, the display device may not be horizontal enough, at this time, the installer can adjust the screw L1 on the two side hangers according to the inclination of the display device, for example, if the left side of the display device is higher, the installer can operate the adjusting screw L1 on the left hanger 150 to push the hanging bar 151 down, lower the left height, or can operate the adjusting screw L1 on the right hanger 150 to drive the hanging bar 151 to rise, raise the right height; if the right side is higher, operate the adjusting screw L1 of the right hanger 150 to lower the right height, in this way, the horizontal inclination angle of the display device is quickly adjusted, or the adjusting screw L1 of the left hanger 150 can be operated to adjust the left height, so that the left hanging bar 151 rises, the left height is increased. Thus, the display device is in a horizontal state, and the viewing effect is improved.
