The wall hanging assembly 100 of the present invention can be used for fixing a wall hanging device on a wall surface, the wall hanging assembly 100 includes a wall pasting board 10 pasted on the wall surface and an installation main board 20 used for connecting with the wall hanging device, and is also provided with a fixing structure 30, the fixing structure 30 includes a retaining member 32 and a limiting member 31 respectively arranged on the wall pasting board 10 and the installation main board 20, and the limiting member 31 encloses to form a limiting slot 31a and a guiding slot 31b communicated with each other, so that the retaining member 32 can slide in the guiding slot 31b towards the limiting slot 31a by passing the retaining member 32 through the opening of the guiding slot 31b and sliding the installation main board 20 relative to the wall pasting board 10, and since the opposite sides of the guiding slot 31b gradually decrease along the direction close to the limiting slot 31a, the retaining member 32 can be limited by the opposite sides of the guiding slot 31b to make the retaining member 32 move towards the limiting slot 31a, when the retaining member 32 slides into the retaining slot 31a, the mounting main board 20 is restricted from moving in a direction away from the wall surface, so as to complete the retaining and fixing between the mounting main board 20 and the wall-mounted board 10. When the installation main board 20 is required to be detached from the wall-attached board 10, the installation main board 20 is required to slide along the limiting clamping groove 31a toward the guiding clamping groove, so that the clamping member 32 is moved to the guiding clamping groove from the limiting clamping groove 31a, and the installation main board 20 can be detached from the wall surface in the direction deviating from the wall surface, thereby improving the operation efficiency of detaching and re-installing the frequently-replaced wall-mounted articles from the wall surface for many times. This dismouting process convenient operation need not the user and deliberately pinpoints that the card holds component 32 and spacing draw-in groove 31a or sets up visual window and observes the removal that the component 32 was held to the card, and then leans on the guide mounting means to realize installing mainboard 20 and pasting the blind installation between the wallboard 10, solves the counterpoint degree of difficulty among the clamping process of hanging installation among the prior art, improves the installation effectiveness, improves the convenience that the user used.

Referring to fig. 1 to 5, in an embodiment of the present application, the retaining member 32 is connected to a surface of the wall panel 10 facing away from the wall surface, the limiting member 31 is connected to a surface of the mounting main plate 20 facing away from the wall hanging device, defining a height direction of the mounting main plate 20, and the limiting slot 31a is located above the guiding slot 31 b. The retaining member 32 and the wall plate 10 can be integrated into a whole, and the position-limiting member 31 and the mounting main board 20 can be integrated into a whole, so as to ensure the structural strength of the retaining member 32 and the position-limiting member 31 when they are connected in a clamping manner. The position-limiting slot 31a is located above the guiding slot 31b, so that the user can mount the main mounting board 20 on the wall-mounted board 10 in a hanging manner from the vertical direction, and the clamping member 32 located on the wall-mounted board 10 can slide into the position-limiting slot 31a more quickly under the action of gravity, thereby further improving the convenience of installation. Of course, the position limiting slot 31a may be located on the left side or the right side of the guiding chute 31b, so that the installation main board 20 may also be moved from the left-right direction to be hung on the wall board 10, which may be selected by a person skilled in the art according to specific situations.

Further, the limiting member 31 includes a limiting block 311 and two guiding plates 312, two guiding plates 312 are connected to the installation main board 20 deviates from the surface of the wall-mounted device, and are symmetrically disposed on two opposite sides of the limiting block 311 to form the guiding sliding groove 31b in a clamping manner, the limiting block 311 is connected to the installation main board 20 deviates from the surface of the wall-mounted device to form the limiting clamping groove 31a in a surrounding manner and to provide an abdicating notch 31c facing the guiding sliding groove 31 b. It can be understood that the distance between the two opposite sides of the guiding slot 31b is greater than the distance between the two opposite sides of the limiting block slot 31a, i.e. the distance between the two guiding plates 312 is greater than the distance between the two opposite sides of the yielding notch 31c of the limiting block 311, so that the retaining member 32 can be more conveniently received in the guiding slot 31b through the notch of the guiding slot 31 b. The two guiding plates 312 may be symmetrically disposed on the left and right sides of the limiting block 311, so that the retaining member 32 can be moved into the limiting slot 31a from any one of the left and right sides, thereby improving the convenience of the user in installation. And one end of the guiding plate 312 departing from the limiting block 311 can extend to the outer wall of the main board 20, so as to increase the area of the guiding chute 31b, and further improve the guiding function of the guiding plate 312.

Furthermore, the two guiding plates 312 are respectively connected to the two opposite groove walls of the receding groove opening 31c of the limiting block 311. The two guiding plates 312 are engaged with the two opposite groove walls of the spacing notch 31c of the limiting block 311, so that when the retaining member 32 slides from the guiding chute 31b to the limiting slot 31a, the retaining member 32 can slide into the limiting slot 31a smoothly in a better engagement manner, and further the retaining member 32 is prevented from being displaced at the connection position between the limiting slot 31a and the guiding chute 31b, so as to improve the installation between the retaining member 32 and the limiting member 31.

Further, the connection between the surface of the guiding plate 312 facing the guiding sliding groove 31b and the groove wall surface of the limiting block 311 is in smooth transition connection. The connection between the guiding plate 312 and the limiting block 311 is smoothly transited, so that the retaining member 32 can slide into the limiting slot 31a more rapidly and smoothly, and the mounting and dismounting efficiency of the retaining member 32 and the limiting member 31 can be further improved.

In an embodiment of the present application, referring to fig. 1 to 5, the limiting block 311 and the two guiding plates 312 are an integral structure. The limiting block 311 and the two guide plates 312 may be integrally formed by injection molding, so that the previous installation process is omitted, and the structural strength of the limiting block 311 and the two guide plates 312 is ensured.
