Detailed Description

As shown in fig. 1 to 6, a self-locking structure applied to an adjustable telescopic wall hanging rack comprises a back plate 100, a front connecting arm 200, an upper connecting arm 300 and a lower connecting arm 400 of the adjustable telescopic wall hanging rack, wherein the back plate 100, the front connecting arm 200, the upper connecting arm 300 and the lower connecting arm 400 form a four-bar hinge mechanism; the upper connecting arm and the lower connecting arm are two connecting rods of a hinge four-bar mechanism, the back plate is a rack of the hinge four-bar mechanism, the front connecting arm is a rod in the hinge four-bar mechanism, which is opposite to the rack, and the front connecting arm used for mounting an object to be hung can be in different states of being far away from or close to the back plate through the up-and-down swing of the upper connecting arm and the lower connecting arm.

The object to be hung can be a display, a liquid crystal display, a mural and the like; when upper and lower linking arm upwards swings, there is an contained angle of 50~80 between upper and lower linking arm and backplate, and when preceding linking arm was in the state of keeping away from with the backplate, the data interface etc. of conveniently treating the hanging article operated, and when upper and lower linking arm swung downwards and is pressing close to the backplate, whole adjustable flexible wall hanger shrink, when preceding linking arm was in the state of pressing close to with the backplate, reduced occupation space, it is more succinct pleasing to the eye.

The lower wall plate 110 of the back plate 100 for hinging the lower connecting arm is provided with a self-locking groove 111, and a hinging shaft (namely a hinging shaft A310 in the figure) between the free end of the upper connecting arm 300 and the front connecting arm 200 is limited in the groove 111 when the front connecting arm is close to the back plate; when the adjustable telescopic wall hanging rack is contracted, in order to prevent the adjustable telescopic wall hanging rack from automatically stretching out, the hinged shaft between the free end of the upper connecting arm 300 of the limiting column of the groove 111 and the front connecting arm 200 is utilized to prevent the adjustable telescopic wall hanging rack from automatically stretching out under the condition of no external force operation, and the front connecting arm can be stably close to the backboard.

In this embodiment, the upper wall plate 120 of the back plate 100 for hinging the upper connecting arm has a through hole for hinging, and a gap for slightly moving the hinging shaft (i.e. hinging shaft B320) upwards is formed between the hinging shaft (i.e. hinging shaft B320 in the figure) between the upper connecting arm and the upper wall plate and the through hole of the upper wall plate; when the object to be hung needs to be pulled out forwards, namely the front connecting arm needs to be adjusted to be away from the back plate, the hinge shaft A310 is separated from the groove through manual operation; when an external force forces the upper connecting arm 300 and the hinge axis a310 to move upward out of the groove; the hinge shaft B320 is also simultaneously moved upward, and the above-mentioned gap provides a space for the hinge shaft B320 to move upward; the specific operation process is as follows: the object to be hung is manually lifted forwards and upwards slightly, the upper connecting arm is forced to move upwards slightly through the object to be hung and the front connecting arm, and then the hinge shaft A310 is separated from the groove, so that the object to be hung and the front connecting arm can be pulled forwards to a position far away from the back plate.

In this embodiment, the front side of the front connecting arm 200 has an intermediate connecting member 500 locked to the back of the object to be hung by a screw, the upper end of the intermediate connecting member 500 has a hook slot for fastening to the upper end edge of the front connecting arm, the lower end of the intermediate connecting member is locked and fixed to the front connecting arm 200 by a screw, the intermediate connecting member 500 serves as a connecting transition member between the object to be hung and the front connecting arm, the intermediate connecting member is first locked to the back of the object to be hung by a bolt, then the intermediate connecting member is hung to the front connecting arm by supporting the object to be hung by the hook slot, and the lower end of the intermediate connecting member is locked and fixed to the front connecting arm 200 by a screw, so as to ensure the stability of the intermediate connecting member 500 and prevent the.

In this embodiment, the lower end of the front connecting arm 200 is provided with a diagonal brace 210 for supporting the lower end of the middle connecting member 500, and the diagonal brace 210 is provided with a screw through hole (i.e. a screw through hole a220 in the figure) for inserting a screw to lock the middle connecting member; in the specific implementation process, a screw through hole (i.e., a screw through hole B230 in the figure) for inserting a screw to lock the intermediate connecting member may be formed in the side wall of the front connecting arm, and the screw on the side surface of the front connecting arm is used to lock the intermediate connecting member.
