[0023] Embodiment of the decorative wall panel:

[0024] Refer to Figures 1 to 5 , which shows the preferred structure of the decorative wall panel in this embodiment. As shown in the figure, the decorative wall panel includes: a main body 1, a plate body 2, a locking device, and a connecting device 3. Among them, a receiving groove 11 recessed from the top (the upper part shown in Figure 1 ) of the main body 1 to the bottom (the lower part shown in Figure 1 ) is provided, and the plate body 2 is placed in the receiving groove 11.

[0025] The locking device is arranged in the receiving groove 11, and the locking device is used to lock the plate body 2 and unlock the plate body 2 when the plate body 2 needs to be replaced.

[0026] The connecting device 3 is arranged at the bottom of the main body 1, and the connecting device 3 is used to detachably connect with the connecting device 3 in the adjacent decorative wall panel, so as to facilitate the connection of two adjacent decorative wall panels.

[0027] It can be seen that in this embodiment, the plate body 2 is placed in the receiving groove 11 at the top of the main body 1, the locking device locks the plate body 2, and unlocks the plate body 2 when the plate body 2 needs to be replaced. There is no need to replace the entire wall panel, and only the plate body 2 needs to be replaced, which reduces the cost and solves the problem that the existing decorative wall panel needs to be replaced as a whole when replaced. Moreover, two adjacent decorative wall panels are detachably connected through the connecting device 3, ensuring the stable connection between two adjacent decorative wall panels and improving the stability and reliability of the connection between adjacent decorative wall panels.

[0028] Refer to Figures 1 to 3, in the above embodiments, the locking device includes: two locking mechanisms 4. Among them, locking grooves 12 are formed on two opposite side walls of the accommodating groove 11, and the two locking mechanisms 4 are correspondingly arranged in the two locking grooves 12 respectively, and the two locking mechanisms 4 lock the plate body 2 from the opposite sides of the plate body 2. Specifically, the accommodating groove 11 may be rectangular in shape, and there are two locking grooves 12, and the two locking grooves 12 are respectively arranged on the opposite sides of the accommodating groove 11. The two locking mechanisms 4 correspond to the two locking grooves 12 one by one, and each locking mechanism 4 is arranged in the corresponding locking groove 12.

[0029] Each locking mechanism 4 may include: a first driving mechanism 41, a transmission mechanism, and a locking plate 43. Among them, the locking plate 43 is movably arranged in the locking groove 12, and the locking plate 43 moves along the depth direction of the locking groove 12, and the depth direction of the locking groove 12 is Figure 3 the direction perpendicular to the paper surface and pointing into the paper as shown. The side of the locking plate 43 facing the center of the accommodating groove 11 is detachably connected to the plate body 2. Specifically, a plurality of protruding columns 5 are arranged on the side of the locking plate 43 facing the center of the accommodating groove 11. A plurality of slots 21 are formed on the side wall of the plate body 2 facing the locking plate 43. The number of the protruding columns 5 is the same as the number of the slots 21, and each protruding column 5 corresponds to each slot 21 one by one, and each protruding column 5 is inserted into the corresponding slot 21.

[0030] During specific implementation, a plurality of protruding columns 5 are arranged on the side of each of the two locking plates 43 of the two locking mechanisms 4 facing the center of the accommodating groove 11, and a plurality of slots 21 are formed on each side wall of each of the two opposite sides of the plate body 2. Each protruding column 5 is inserted into each slot 21.

[0031] The first driving mechanism 41 is arranged in the locking groove 12. The first driving mechanism 41 is connected to the locking plate 43 through the transmission mechanism. The first driving mechanism 41 is used to drive the locking plate 43 to move towards the center of the accommodating groove 11, so that the locking plate 43 approaches the plate body 2 and then the locking plate 43 is detachably connected to the plate body 2. The first driving mechanism 41 is also used to drive the locking plate 43 to move away from the center of the accommodating groove 11, that is, to move towards the inside of the locking groove 12, so that the locking plate 43 moves away from the plate body 2, and then the locking plate 43 is separated from the plate body 2. At this time, each protruding column 5 moves out of each slot 21, and the plate body 2 can be disengaged from the locking of the locking plate 43, realizing the unlocking of the plate body 2, and the plate body 2 can be taken out of the accommodating groove 11 for replacement.

[0032] An opening is formed on a side wall of the accommodating groove 11 adjacent to the locking groove 12. Specifically, two side walls of the accommodating groove 11 are provided with locking grooves 12, and an opening is formed on one of the other two side walls of the accommodating groove 11, and this opening enables the accommodating groove 11 to communicate with the outside.

[0033] The first driving mechanism 41 may be a driving plate.

[0034] The transmission mechanism may include: two gears 42. Among them, the two gears 42 are rotatably arranged on the side walls of the locking groove 12. Specifically, the locking groove 12 has two opposite side walls and a bottom wall. The two side walls are located in the height direction of the locking groove 12 ( Figure 3 the direction from top to bottom as shown), one of the side walls is the lower side wall in the height direction of the locking groove 12, and the other side wall is the upper side wall in the height direction of the locking groove 12. The two gears 42 are rotatably arranged on the lower side wall in the height direction of the locking groove 12, and, the two gears 42 are arranged side by side in the locking groove 12 along the length direction of the locking groove 12 ( Figure 3 the direction from left to right as shown). The length direction of the locking groove 12 is perpendicular to the depth direction. One of the gears 42 is closer to the opening of the accommodating groove 11 than the other gear 42. The two gears 42 are meshed with each other so that the two gears 42 can rotate simultaneously.

[0035] The driving plate corresponds to the opening. When the plate body 2 is in the locked state, the driving plate is horizontally arranged at the opening and blocks the opening. When the plate body 2 is in the unlocked state, the driving plate can rotate outwards. The driving plate is connected to the gear 42 closer to the opening. The locking plate 43 is provided with meshing teeth, and, the meshing teeth on the locking plate 43 are meshed with the other gear 42.

[0036] The driving plate is used to block the opening after the plate body 2 is locked and rotate outwards from the opening under the action of an external force to drive the two gears 42 to rotate, and then drive the locking plate 43 to move away from the center of the accommodating groove 11.

[0037] Specifically, after the plate body 2 is locked, the driving plates in the two locking mechanisms 4 are opposite to each other. The two driving plates are horizontally arranged at the opening, and the two driving plates block the opening of the accommodating groove 11. Under the action of an external force, the two driving plates are rotated simultaneously. The two driving plates rotate outwards from the opening. Each driving plate drives the gear 42 connected to it to rotate, and then drives the other gear 42 to rotate, and then drives the locking plate 43 to move away from the center of the accommodating groove 11, that is, move deep into the locking groove 12. The two locking plates 43 are separated from the plate body 2, and then the convex column 5 is separated from the slot 21, that is, the unlocking of the plate body 2 is realized. When the new plate body 2 needs to be locked after the plate body 2 is replaced, the two driving plates are rotated simultaneously. The two driving plates rotate towards the opening. Each driving plate drives the locking plate 43 to move towards the center of the accommodating groove 11 through the two gears 42. The two locking plates 43 are in contact with the plate body 2, and then the convex column 5 is inserted into the slot 21, that is, the locking of the plate body 2 is realized.

[0038] It can be seen that in this embodiment, the locking device has a simple structure and is easy to implement.

[0039] See Figure 1 、 Figures 4 to 5 , in the above embodiments, the connecting device 3 includes: a mounting plate 31, a frame body 32, a second driving mechanism, and four connecting members 35. Among them, the mounting plate 31 is disposed at the bottom of the body 1 ( Figure 1 the lower part shown), the top wall of the mounting plate 31 ( Figure 1 the upper wall shown) is connected to the bottom of the body 1. The mounting plate 31 has a certain thickness, which can be determined according to the actual situation, and this embodiment does not impose any restrictions on this. A cross-shaped cavity 6 is provided inside the mounting plate 31, and the cross-shaped cavity 6 penetrates through the mounting plate 31 to communicate with the outside. The cross-shaped cavity 6 penetrates out from the four side walls of the mounting plate 31 so that the cross-shaped cavity 6 communicates with the outside.

[0040] The frame body 32 is cross-shaped, and the top of the frame body 32 ( Figure 5 the upper part shown) is disposed inside the cross-shaped cavity 6, and the bottom of the frame body 32 ( Figure 5 the lower part shown) is provided with a cross-shaped groove.

[0042] The second driving mechanism is disposed at the central position of the cross-shaped groove, and the second driving mechanism is connected to all four connecting members 35. The second driving mechanism is used to drive the four connecting members 35 to move along the corresponding slot rails 7 so that the four connecting members 35 can slide out of the cross-shaped cavity 6, and the four connecting members 35 can be detachably connected to the corresponding connecting members 35 in the adjacent decorative wall panels after sliding out of the cross-shaped cavity 6.

[0043] The second driving mechanism may include: a driving body 33 and four linkage components 34. Among them, a sliding groove is provided at the central position of the cross-shaped groove of the frame body 32, and the sliding groove extends along the thickness direction of the frame body 32 ( Figure 4 the direction from top to bottom shown). The driving body 33 is slidably disposed in the sliding groove, and one end of the driving body 33 ( Figure 4 the lower end shown) is slidably passed through the mounting plate 31 and placed outside the mounting plate 31. Specifically, a through hole is provided in the bottom wall of the mounting plate 31 corresponding to the driving body 33, and the driving body 33 is slidably passed through the through hole, and one end of the driving body 33 ( Figure 4 the lower end shown) is placed outside the mounting plate 31.

[0044] The four linkage components 34 are all connected to the driving body 33, and the four linkage components 34 correspond to the four connecting pieces 35 one by one, and each linkage component 34 is connected to the corresponding connecting piece 35. The driving body 33 is used to slide in the sliding groove to drive the four connecting pieces 35 to move through the four linkage components 34.

[0045] Preferably, the outer wall of the driving body 33 is provided with meshing teeth. The four linkage components 34 correspond to the four groove rails 7 one by one. Each linkage component 34 is a linkage gear, and each linkage gear is arranged in the corresponding groove rail 7 of the cross-shaped groove. Moreover, each linkage gear meshes with the driving body 33.

[0046] On one side of each connecting piece 35 facing the linkage gear, meshing teeth are provided. Each connecting piece 35 meshes with the corresponding linkage gear. The setting position of the meshing teeth on each connecting piece 35 should ensure that the rotation of the linkage gear causes the connecting piece 35 to move in the corresponding groove rail 7. The driving body 33 is used to slide in the sliding groove, drive the four linkage gears to rotate, and then drive the four connecting pieces 35 to move.

[0047] Each connecting piece 35 includes: a first connecting body 351 and a second connecting body 352.

[0050] Combined Figures 1 to 5 The use process of the decorative wall panel is introduced as follows:

[0051] When the plate body 2 needs to be replaced, the two driving plates are turned outwards. The rotation of the two driving plates causes the rotation of each driving plate to drive the two gears 42 to rotate, and then drive the locking plate 43 to move deeper into the locking groove 12. The locking plate 43 is separated from the plate body 2, and the respective protruding columns 5 are disengaged from the insertion slots 21 of the plate body 2, that is, the locking of the plate body 2 is released. At this time, the staff can replace the plate body 2.

[0052] After replacing the new board body 2, turn the two drive boards inward. The rotation of the two drive boards drives the respective gears 42 to rotate, and further drives the respective locking plates 43 to move towards the center of the accommodation groove 11. Each protruding column 5 on the locking plate 43 can be inserted into the corresponding slot 21 of the board body 2, thus realizing the locking of the board body 2.

[0053] When it is necessary to connect two decorative wall panels, attach the bottom wall of the mounting plate 31 to the wall surface, press the main body 1, the driving body 33 is squeezed, the driving body 33 slides along the sliding groove, and the sliding of the driving body 33 drives the four interlocking gears to rotate simultaneously.
