Detailed Description
The first embodiment is as follows: as shown in fig. 1 to 5, an upper and lower connecting arm structure of an ultra-thin adjustable telescopic wall hanging rack includes an upper connecting arm 100 and a lower connecting arm 200 which form a hinge four-bar mechanism with a back plate and a front connecting arm on the ultra-thin adjustable telescopic wall hanging rack and can swing up and down, the upper and lower connecting arms are two connecting rods of the hinge four-bar mechanism, the back plate is a rack of the hinge four-bar mechanism, the front connecting arm is a rod opposite to the rack in the hinge four-bar mechanism, the upper and lower connecting arms are flat bar-shaped groove-shaped members and are not overlapped in the length direction when rotating to be close to the back plate, and through the up-and-down swing of the upper and lower connecting arms, the front connecting arm used for installing an object to be hung.
The object to be hung can be a display, a liquid crystal display, a mural and the like; when the upper connecting arm and the lower connecting arm swing upwards, an included angle of 50-80 degrees is formed between the upper connecting arm and the back plate, when the front connecting arm and the back plate are in a far state, a data interface and the like of an object to be hung can be conveniently operated, when the upper connecting arm and the lower connecting arm swing downwards to be close to the back plate, the whole adjustable telescopic wall hanging frame contracts, and when the front connecting arm and the back plate are in a close state; the upper connecting arm and the lower connecting arm which are in the shape of flat bar grooves have higher strength, and have better mechanical property compared with the entity connecting arm with the same weight; when the upper connecting arm and the lower connecting arm rotate to be close to the back plate, the whole suspension frame contracts, and the length of the upper connecting arm and the length of the lower connecting arm enable the suspension frame not to be overlapped when the suspension frame contracts, so that the contracted thickness of the whole suspension frame can be reduced; in the specific implementation process, the front connecting arm also adopts a flat strip-shaped trough-shaped component, and when the suspension bracket contracts, the upper connecting arm and the lower connecting arm can be overlapped with the front connecting arm in a matching way, so that the thickness is further reduced, and the compact structure and the ultrathin thickness are realized.
In this embodiment, the lower connecting arm has two parallel dislocated channels 500, the notches of the two channels are opened in opposite directions, the channels are arranged along the length direction of the connecting arm, and the flat-bar-shaped groove-shaped lower connecting arm achieves the requirement of mechanical property, so that the structure is compact and the weight is light.
In this embodiment, the lower connecting arm 200 has lower wall plates 210 at both ends for hinging with the hinge shaft, lower through holes 211 for hinging on the lower wall plates, the lower through holes on the lower wall plates at the same end of the lower connecting arm are coaxial, the lower wall plates are located at both sides of the end part of the upper channel of the lower connecting arm,
in this embodiment, the upper connecting arm has a single channel 500, which is arranged along the length direction of the connecting arm, and the flat-bar-shaped groove-shaped upper connecting arm achieves the requirement of mechanical property, so that the structure is compact and the weight is light.
In this embodiment, the two ends of the upper connecting arm are provided with upper side wall plates 110 hinged with the hinge shaft, the upper side wall plates are provided with upper through holes 111 hinged with the hinge shaft, the upper through holes on the side wall plates at the same end of the upper connecting arm are coaxial, and the upper side wall plates are positioned at two sides of the end part of the upper channel of the upper connecting arm.
In this embodiment, the lower connecting arm is longer in length than the upper connecting arm.
Example two: as shown in fig. 6 to 7, the difference between this embodiment and the first embodiment lies in that the number of the channels on the upper connecting arm is different, in order to increase the strength of the upper connecting arm and ensure the structural stability, the upper connecting arm has two channels which are offset in parallel, the notches of the two channels open in opposite directions, and the channels are arranged along the length direction of the connecting arm; the use of an upper link arm with two parallel offset channels provides better stability, while the implementation of an upper link arm with a single channel provides greater ease of installation.
Example three: as shown in fig. 8 to 9, the difference between this embodiment and the first embodiment is that the number of the slots on the lower connecting arm is different, and in this embodiment, the lower connecting arm has a single slot, which reduces the requirement for the installation accuracy, so as to facilitate the installation of the lower connecting arm.
