[0040] First limiting members 5 are also provided at both ends of the first mating groove 6, and a gap is provided between the first limiting member 5 and the bottom of the first mating groove 6. When the pressing member 4 moves toward the first mating groove 6, the two locking units move away from each other until the locking unit moves into the gap between the first limiting member 5 and the first mating groove 6, so that the first limiting member 5 limits the locking unit.

[0041] During the installation process, the male end wall fitting and the female end wall fitting are installed and connected through the cooperation of the first plug-in component and the first plug-in slot 6. When the first plug-in component and the first plug-in slot are cooperated, first align the pressing piece 4 with the first plug-in slot 6, and then press the pressing piece 4 to make the two locking units move away from each other until the locking unit and the first limiting piece 5 form a limiting cooperation, so that the locking unit cannot move back, and the male end wall fitting and the female end wall fitting are installed and connected, which ensures the installation efficiency while also improving the stability of the connection structure.

[0042] In one embodiment, referring to Figure 1 As shown, it also includes at least one wall mid-end fitting, which is arranged between the wall male end fitting and the wall female end fitting, and the wall mid-end fitting includes: a third wall panel 7, a second plug-in component and a second plug-in groove, the second plug-in component and the second plug-in groove are respectively arranged at the opposite ends of the third wall panel 7, the structure of the second plug-in component is the same as that of the first plug-in component, and second limit members are also provided at both ends of the second plug-in groove, and the structure of the second limit member is the same as that of the first limit member 5.

[0043] The length of the overall structure is extended by the wall middle end fittings arranged between the wall male end fittings and the wall female end fittings to meet different wall height requirements.

[0044] In one embodiment, referring to Figure 2-Figure 3 As shown, the locking unit comprises:

[0045] The rotating seat 8 is fixedly connected to the pressing member 4 and is provided with a

[0046] The rotating shaft 9 is sleeved with

[0047] A swing rod 10, a first end of which swings around the rotation axis 9, and a second end of which is hinged to a

[0048] The positioning shaft 11 is sleeved with a

[0049] When the pressing member 4 moves toward the first mating groove 6 , the swing rod 10 rotates around the rotating shaft 9 so that the plug-in block 12 is plugged into the gap between the first limiting member 5 and the first mating groove 6 .

[0050] After pressing the pressing piece 4, the plug-in block 12 abuts against the bottom of the first mating groove 6 and cannot move in the same direction as the pressing piece 4, so that the swing rod 10 swings around the rotating shaft 9 and drives the plug-in block 12 to move into the gap between the first limiting piece 5 and the first mating groove 6 through the positioning shaft 11.

[0051] In one embodiment, referring to Figure 3 As shown, the first limiting member 5 includes a mounting portion 501 and an extension portion 502, the mounting portion 501 is connected to the first wall panel 1, the extension portion 502 is parallel to the bottom of the first mating groove 6 to form a gap, and the plug-in block 12 moves along the gap between the extension portion 502 and the first mating groove 6.

[0052] It is connected to the first wall panel 1 through the mounting portion 501, and a gap is formed between the extension portion 502 and the bottom of the first mating groove 6, so that the plug-in block 12 can be plugged into the gap. The extension portion 502 limits the plug-in block 12 to prevent the plug-in block 12 from escaping from the gap, making the connection between the male wall fitting and the female wall fitting more stable.

[0053] In one embodiment, referring to Figure 3 As shown, a hemispherical stopper 13 is further provided on one side of the extension portion 502 facing the plug-in block 12 , and a first rounded corner matching with the stopper 13 is provided at a corner of the plug-in block 12 .

[0054] The stopper 13 disposed on one side of the extension portion 502 limits the plug-in block 12 from leaving the gap, thereby further improving the stability of the plug-in block 12 after being installed in the gap.

[0055] In one embodiment, referring to Figure 3 As shown, the stopper 13 is an elastic structure. When the plug-in block 12 moves to the stopper 13, the stopper 13 contracts inwardly.

[0056] Preferably, the check piece 13 can be made of any elastic material such as rubber. When the plug-in block 12 moves into the gap to the check piece 13, the check piece 13 contracts, allowing the plug-in block 12 to pass smoothly. When the check piece 13 continues to move, the check piece 13 gradually recovers until it is fully recovered to limit the plug-in block 12.

[0057] In one embodiment, referring to Figure 3 As shown, the mounting portion 501 is provided with a locking groove 14, and the plug-in block 12 is also connected to a positioning block 15 matched with the locking groove 14 on one side facing the mounting portion 501, and receiving grooves are provided on both sides of the positioning block 15, and a positioning unit is provided in the receiving groove, and positioning grooves 16 matched with the positioning unit are provided on the groove walls on both sides of the locking groove 14, and when the pressing member 4 moves toward the first plug-in groove 6, the positioning block 15 moves toward the locking groove 14 until the positioning unit moves to the positioning groove 16.

[0058] When the plug-in block 12 is moved into position, the positioning unit provided in the receiving groove cooperates with the positioning groove 16 to limit the moving direction of the plug-in block 12, thereby further improving the stability of the plug-in block 12 after being plugged into position.

[0059] In one embodiment, referring to Figure 3 As shown, a second rounded corner is provided at the notch of the locking groove 14, and a third rounded corner matched with the second rounded corner is provided at the end of the positioning block 15.

[0060] The cooperation between the third rounded corner at the end of the positioning block 15 and the second rounded corner at the notch of the locking groove 14 can improve the smoothness of the positioning block 15 when it is inserted into the locking groove 14 .

[0061] In one embodiment, referring to Figure 3 As shown, the positioning unit includes: a ball 17 and a spring 18 abutting against each other, the spring 18 is arranged in the receiving groove, and the ball 17 is arranged at the notch of the receiving groove.

[0062] During the movement of the positioning block 15, the ball 17 rolls along the groove wall of the locking groove 14. At the same time, the spring 18 is in a contracted state. When the ball 17 moves to the positioning groove 16, the ball 17 is locked into the positioning groove 16 under the action of the spring 18, thereby limiting the movement of the positioning block 15. At this time, the positioning block 15 moves into place, further preventing the plug-in block 12 from detaching.

[0063] In one embodiment, referring to Figure 3 As shown, the mounting portion 501 is connected to the first wall panel 1 via locking bolts 19 .

[0064] The mounting portion 501 is connected to the first wall panel 1 by means of locking bolts 19, which reduces the connection cost and increases the efficiency of on-site installation.
