Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of support, and relates to a hanging arm assembly, in particular to a display hanging support with a hanging arm assembly. BACKGROUND

[0002] The adjustable hanging arm zero-limiting structure is a mechanical design, which is usually used in a hanging device or a supporting arm that needs to be adjusted in angle. The main purpose of this structure is to ensure that the hanging arm can be accurately limited and fixed at a specific position (i.e. zero position), preventing it from moving or deviating accidentally. The design of this structure is very important for ensuring the safety and functionality of the equipment.

[0003] At present, the adjustable hanging arm zero-limiting structures on the market generally have the following structures: knob locking structure, magnetic structure and fixed slot buckle structure. As for the knob locking structure, the adjustable hanging arm is first adjusted to the vertical zero position, and the knob on the hanging arm is tightened to maintain the zero position by increasing the friction. However, when the space between the display hanging support and the wall is limited, the tightening operation cannot be completed. As for the magnetic structure, the adjustable hanging arm is first adjusted to the vertical zero position, and the strong magnet at the hook holds the hanging arm to maintain the zero position by magnetic force. However, the magnetic structure has high cost and unstable magnetism, and there is a risk of the display falling from the display hanging support, and the applicable range of the display weight is limited. As for the fixed slot buckle structure, the metal slot on the hanging arm is buckled into the corresponding positioning rod on the hook to maintain the zero position of the hanging arm. However, the metal slot needs a large force to be buckled into the positioning rod, which is not good for experience, and the structure requires high assembly precision of the product. SUMMARY

[0041] The following is a specific embodiment of the present application and further describes the technical solution of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0042] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0043] like Figures 1 to 7 As shown, the present invention provides a hanging arm assembly, comprising:

[0044] The first arm 10 and the second arm 20 are movable relative to each other. The first arm 10 is provided with a snap-fit ​​member 30 having a communicating opening and a receiving groove 31. The second arm 20 is provided with a snap-fit ​​part 40 for snapping into the receiving groove 31 through the opening. The snap-fit ​​member 30 and / or the snap-fit ​​part 40 are provided with an elastic deformation part 32 to facilitate the snap-fit ​​of the snap-fit ​​member 30 and the snap-fit ​​part 40.

[0045] The snap-fit ​​part 40 is movably connected to the second arm 20.

[0046] Furthermore, the elastic deformation part 32 is provided on the snap-fit ​​part 30; the snap-fit ​​part 40 is a cylindrical part, the width of the opening is smaller than the diameter of the cylindrical part, and the internal shape of the receiving groove 31 is adapted to the external shape of the snap-fit ​​part 40.

[0047] When the snap-fit ​​part 40 snaps into the snap-fit ​​member 30, the deformation of the elastic deformation part 32 causes the opening width of the snap-fit ​​member 30 to increase; after the snap-fit ​​part 40 snaps into the snap-fit ​​member 30, the elastic deformation part 32 returns to its original state, and the snap-fit ​​part 40 is accommodated in the receiving groove 31 to limit the relative position between the first arm 10 and the second arm 20.

[0048] It is worth mentioning that the deformation of the elastic deformation part 32 changes the opening size of the receiving groove 31. That is, when the snap-fit ​​part 40 snaps into the snap-fit ​​part 30, the opening of the receiving groove 31 becomes larger, thus facilitating the snap-fit ​​part 40 to snap in; after the snap-fit ​​part 40 snaps into the snap-fit ​​part 30, the opening of the receiving groove 31 retracts, thus firmly gripping the snap-fit ​​part 40 and preventing the snap-fit ​​part 40 from slipping out of the receiving groove 31. This snap-fit ​​method enables quick assembly and disassembly between the first arm 10 and the second arm 20, improving work efficiency.

[0049] The present invention provides a hanging arm assembly, which enables quick assembly and disassembly between the first arm 10 and the second arm 20 by providing corresponding snap-fit ​​parts 30 with receiving grooves 31 on the first arm 10 and the second arm 20, thereby improving work efficiency, being unrestricted by space, applicable to a variety of display devices, and providing a better user experience.

[0050] It is further pointed out that the clamping member 30 in the embodiment is generally made of a deformable hard material, such as plastic, so that the opening of the clamping member 30 can be deformed when the clamping portion 40 is clamped into the clamping member 30, thereby facilitating the clamping of the clamping portion 40.

[0051] In addition, in the embodiment, when the clamping portion 40 is clamped into the clamping member 30, the clamping portion 40 is clamped into the clamping member 30 from the bottom to the top, and at this time, the elastic deformation portion 32 is arranged on the lower side of the opening of the clamping member 30; when the clamping portion 40 is clamped into the clamping member 30, the clamping portion 40 is clamped into the clamping member 30 from the top to the bottom, and at this time, the elastic deformation portion 32 is arranged on the upper side of the opening of the clamping member 30.

[0052] It is further preferred that the clamping portion 40 is sleeved with a shaft sleeve 41, and the shaft sleeve 41 is rotatably connected with the clamping portion 40.

[0053] It is preferred that the first arm 10 and the second arm 20 are both arranged in a U shape, and the opening direction of the first arm 10 is consistent with the opening direction of the second arm 20, wherein the clamping member 30 is arranged at the closed end of the first arm 10, and the clamping portion 40 is arranged on both sides of the opening of the second arm 20.

[0054] It is worth mentioning that the opening size of the opening end of the first arm 10 is greater than the opening size of the opening end of the second arm 20, and it is further pointed out that the relative distance between the two inner walls of the opening end of the first arm 10 is greater than the relative distance between the two outer walls of the opening end of the second arm 20. Such arrangement, when the clamping portion 40 is clamped into the clamping member 30, the second arm 20 can be embedded into the first arm 10, thereby further reducing the thickness of the entire hanging arm assembly after the clamping of the first arm 10 and the second arm 20, on the one hand, the hanging arm assembly can adapt to smaller space installation, further expanding the application range of the entire hanging arm assembly, on the other hand, when the display device is connected to the hanging arm assembly, the display device is closer to the wall, reducing the risk of collision of the display device, improving the safety of the display device.

[0055] It is preferred that the two ends of the first arm 10 and the two ends of the second arm 20 are respectively connected through a first connecting member 60 and a second connecting member 70, and the first connecting member 60 is arranged in a U shape, and the second connecting member 70 is arranged in a chevron shape, wherein the first connecting member 60 is arranged at one end away from the clamping portion 40, and the second connecting member 70 is arranged at one end close to the clamping portion 40, and the two ends of the first connecting member 60 are respectively rotatably connected with the first arm 10 and the second arm 20, and the second connecting member 70 includes a first connecting strip 71 and a second connecting strip 72, and the two ends of the first connecting strip 71 are respectively rotatably connected with the first arm 10 and the second arm 20, one end of the second connecting strip 72 is rotatably connected with the first connecting strip 71, and the other end of the second connecting strip 72 is slidably connected with the first arm 10.

[0056] It is worth mentioning that when the first arm 10 and the second arm 20 are opened, i.e. in the unclamped state, the whole hanging arm assembly is arranged in a V-shaped structure; when the first arm 10 and the second arm 20 are closed, i.e. in the clamped state, the whole hanging arm assembly is arranged in a "1" shape.

[0057] In the embodiment, the connection mode between the first arm 10 and the second arm 20 is not limited to the above-mentioned connection mode, and other connection modes can also be adopted, such as a scissors type connection structure to realize the connection between the first arm 10 and the second arm 20, as long as the connection mode can meet the requirement that the first arm 10 can move up and down during the quick disassembly and assembly of the first arm 10 and the second arm 20.

[0058] Preferably, in order to improve the stability and reliability of the first arm 10 and the second arm 20 after being connected, two clamping pieces 30 are arranged side by side on the first arm 10, and an avoiding groove 11 is arranged on the side wall of the first arm 10 corresponding to the clamping piece 30, wherein the opening direction of the avoiding groove 11 is consistent with the opening direction of the opening of the clamping piece 30, and the extension direction of the clamping piece 30 passes through the avoiding groove 11.

[0059] It is worth mentioning that since the first arm 10 is arranged in a U-shaped structure and the clamping piece 30 is also arranged in a U-shaped structure, the connection between the clamping piece 30 and the first arm 10 is that the closed end of the clamping piece 30 is connected to the closed end of the first arm 10, and the opening direction of the clamping piece 30 is consistent with the opening direction of the first arm 10. When the opening size of the opening end of the first arm 10 is slightly larger than the opening size of the opening end of the second arm 20, avoiding grooves 11 can be arranged on both sides of the opening end of the first arm 10, i.e. the accommodating grooves 31 pass through both sides of the opening end of the first arm 10, so as to avoid interference with the clamping part 40; when the opening size of the opening end of the first arm 10 is much larger than the opening size of the opening end of the second arm 20, the avoiding grooves 11 can not be arranged on both sides of the opening end of the first arm 10, at this time, the first arm 10 has enough space to accommodate the first arm 10, the clamping piece 30 and the clamping part 40. However, such a setting will result in an increase in the width of the whole first arm 10, which will increase the manufacturing material of the first arm 10, i.e. increase the manufacturing cost of the hanging arm assembly. Therefore, in order to ensure the compactness of the structure of the whole hanging arm assembly and control the manufacturing cost of the hanging arm assembly, the avoiding grooves 11 are generally arranged on both sides of the opening of the first arm 10 corresponding to the clamping piece 30, so as to avoid interference with the clamping part 40.

[0060] Preferably, the side of the opening on which the elastic deformation part 32 is arranged is further provided with a guide part 33, and the guide part 33 extends obliquely in a direction away from the opening, wherein when the clamping part 40 is clamped with the opening, the clamping part 40 promotes the deformation of the elastic deformation part 32 through the guide part 33.

[0061] It is worth mentioning that the guide part 33 is integrally arranged with the elastically deformed part 32, and when the clamping part 40 is clamped into the clamping piece 30 from bottom to top, the guide part 33 extends downwardly and away from the opening of the clamping piece 30; when the clamping part 40 is clamped into the clamping piece 30 from top to bottom, the guide part 33 extends upwardly and away from the opening of the clamping piece 30.

[0062] In the embodiment, by arranging the guide part 33 on one side of the elastically deformed part 32, when the clamping part 40 is clamped into the clamping piece 30, on one hand, the clamping part 40 will not collide with the end face of the opening of the clamping piece 30, so that the clamping part 40 can be smoothly clamped into the clamping piece 30, on the other hand, the guide part 33 can more effectively trigger the deformation of the elastically deformed part 32, so that the clamping part 40 can be smoothly clamped into the clamping piece 30.

[0063] Further preferably, the elastically deformed parts 32 are arranged on both sides of the opening, and the elastically deformed parts 32 are arranged in an arc shape, wherein when the clamping part 40 is clamped into the clamping piece 30, the centers of the circles formed by the two elastically deformed parts 32 are flush with the center of the clamping part 40.

[0064] In the embodiment, the centers of the circles formed by the two elastically deformed parts 32 are flush with the center of the clamping part 40, so that the two sides of the opening of the clamping piece 30 can fully contact the side surface of the clamping part 40, that is, the two elastically deformed parts 32 can tightly wrap the clamping part 40, so as to avoid the clamping part 40 from sliding out of the clamping piece 30, and improve the stability and reliability of the entire hanging arm assembly.

[0065] Preferably, one end of the clamping piece 30 connected with the first arm 10 is provided with a connecting channel 34, the axis direction of the connecting channel 34 is consistent with the opening direction of the opening of the clamping piece 30, and a thread is arranged on the side wall of the connecting channel 34, wherein the fixing between the clamping piece 30 and the first arm 10 is completed through the cooperation between the thread and a fastener 36; or one end of the clamping piece 30 connected with the first arm 10 is provided with a connecting channel 34, the axis direction of the connecting channel 34 is consistent with the opening direction of the opening of the clamping piece 30, and a nut 35 is arranged in the connecting channel 34, wherein the fixing between the clamping piece 30 and the first arm 10 is completed through the connection between the nut 35 and the fastener 36.

[0066] It is worth mentioning that no matter the fastener 36 is directly screwed with the internal thread of the inner wall of the connecting channel 34 or is screwed with the nut 35 in the connecting channel 34, the connection between the fastener 36 and the first arm 10 is generally in two modes, one is that a connecting hole is arranged on the first arm 10, the fastener 36 is penetrated through the connecting hole from the back surface of the first arm 10 and is screwed into the connecting channel 34 to realize the connection between the clamping piece 30 and the first arm 10, and the other is that the tail of the fastener 36 is directly welded on the first arm 10, and then the clamping piece 30 is screwed on the fastener 36 through the connecting channel 34 to complete the connection between the clamping piece 30 and the first arm 10. The above two modes can realize the connection between the clamping piece 30 and the first arm 10.

[0067] In addition, for the first connection mode, in order to ensure the flatness of the adhesion between the first arm 10 and the display device, the connecting hole can be designed as a counterbore, so that the tail of the fastener 36 does not protrude from the back surface of the first arm 10, and the display device does not tilt after being connected with the first arm 10.

[0068] Preferably, the second arm 20 is provided with an oblong hole 21 on each side, and the clamping part 40 passes through and is slidingly fitted in the two oblong holes 21.

[0069] In the embodiment, the oblong hole 21 is arranged to enable the clamping part 40 to move up and down along the length direction of the second arm 20, which facilitates the smooth clamping of the clamping part 40 into the clamping piece 30 and ensures that the center of the clamping part 40 clamped in the clamping piece 30 is flush with the center of the clamping piece 30, so that the clamping piece 30 can tightly wrap the clamping part 40, avoiding the clamping part 40 from sliding out of the clamping piece 30, and improving the stability and reliability of the whole hanging arm assembly.

[0070] Preferably, the hanging arm assembly further comprises a connecting rod 50, and the two ends of the connecting rod 50 are respectively inserted into the oblong holes 21 and extend outward, wherein the two ends of the connecting rod 50 are movably connected with the clamping parts 40.

[0071] It is worth mentioning that the clamping parts 40 located on both sides of the opening of the second arm 20 can be independently arranged or connected through the connecting rod 50 to form a whole, wherein the clamping parts 40 located at the two ends of the connecting rod 50 are rotatably connected with the corresponding ends of the connecting rod 50, so that when the clamping parts 40 are clamped into the clamping piece 30, the sliding friction between them is changed into rolling friction, and the disassembly of the first arm 10 and the second arm 20 is more time-saving and labor-saving.

[0072] The application also provides a display hanging rack, comprising:

[0073] The wall connecting piece 80 and the two hanging arm assemblies are hung on the wall connecting piece 80.
