Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] Reference example Figures 1 to 4 A hanging plate hardware with stable connection includes a hanging plate 1, a bolt 2, and a nut 3. The hanging plate 1 is provided with a fixing hole 11, and the fixing hole 11 is provided with a clearance through hole 12. The side walls of the clearance through hole 12 are provided with a fixing groove 13 and are located on both sides of the hanging plate 1. The fixing groove 13 is provided with a plurality of first convex bumps 131 with equal spacing 5. The bolt 2 is inserted into the fixing hole 11, and the rod of the bolt 2 is provided with a limit block 4 and is arranged in the clearance through hole 12. The limit block 4 is provided with a countersunk hole 41. The bolt 2 is rotated to make the limit block 4 abut against the side wall of the fixing groove 13, so that the first convex bump 131 is embedded in the countersunk hole 41, and the nut 3 is threadedly connected with the bolt 2 and abuts the hanging plate 1, the horizontal left and right displacement of the limit block 4 is limited by the fixing groove 13, the impact force of the hanging plate 1 on the nut 3 is reduced, and the deformation of the threaded connection between the nut 3 and the bolt 2 is prevented, resulting in a decrease in the connection strength. When the connecting hardware rotates with the bolt 2 as the axis due to the shaking of the wire, the first convex bump 131 prevents the countersunk hole 41 from being separated. If the shaking amplitude is too large, the countersunk hole 41 will temporarily separate from one of the first convex bumps 131, but there are still multiple first convex bumps 131 to prevent the limit block 4 from being separated from the fixing groove 13, and prevent the bolt 2 from rotating with the connecting hardware, thereby ensuring the connection stability between the nut 3 and the bolt 2;

[0025] It is worth mentioning that the hanging plate 1 is provided with an opening 14, the fixing hole 11 passes through the opening 14, the hanging plate 1 is provided with a fixing sheet metal 15, and is arranged crosswise with the opening 14, and the fixing sheet metal 15 is provided with a perforation 16. When other connecting hardware such as the second connecting plate and the extended pull ring enter the opening 14, the opening 14 plays a role in limiting the range of movement of the connecting hardware. The bolt 2 is inserted through the fixing hole 11 to connect the connecting hardware to the hanging plate 1, and the perforation 16 facilitates connection with other connecting hardware;

[0026] It is worth mentioning that the surface where the hanging plate 1 abuts against the nut 3 is evenly distributed with a plurality of second convex bumps 17 with the point of the fixing hole 11 as the axis, and the second convex bumps 17 serve to increase the friction between the nut 3 and the hanging plate 1, and improve the connection stability between the nut 3 and the bolt 2;

[0027] It is worth mentioning that the rod of the bolt 2 is provided with at least two avoidance through holes 21, and the head and tail of the bolt 2 are provided with threaded holes 22, which pass through the avoidance through holes 21. The avoidance through holes 21 provide accommodation space and support points for the limit block 4, and the threaded holes 22 are convenient for

[0028] It is worth mentioning that the limit block 4 is inserted into the avoidance through hole 21, and the threaded hole 22 is provided with a fastening screw 7, which passes through the limit block 4, so that the bolt 2 is connected and fixed to the limit block 4, and a spacing 5 is provided between the limit block 4 and the bottom of the fixing groove 13. Chamfers 6 are provided on the left and right sides of the limit block 4 and the entrance of the countersunk hole 41. The fastening screw 7 prevents the limit block 4 from being separated from the avoidance through hole 21 to ensure the connection stability. The spacing 5 prevents the first convex bump 131 from entering the countersunk hole 41, because there is no margin between the two, resulting in a hard collision between the components. The first convex bump 131 will be flattened by the limit block 4 or the limit block 4 is forced to enter and reduce the height of the first convex bump 131. The chamfer 6 facilitates the limit block 4 and the countersunk hole 41 to enter the countersunk hole 41;

[0029] It is worth mentioning that the detachable fastening screw 7 is convenient for passing the bolt 2 through the connecting hardware during installation, and then the limit block 4 is connected and fixed with the avoidance through hole 21, or when the limit block 4 or the bolt 2, the first convex bump 131, and the second convex bump 17 are damaged, they can be replaced to improve resource utilization;

[0030] It is worth mentioning that the number of the clearance holes 12 is set to at least two, and they are arranged in opposition. The number of the limit blocks 4 corresponds to the number of the clearance holes 12. The clearance holes 12 cooperate with the limit blocks 4 to pass through and enter the fixed grooves 13, which are arranged in opposition, so that the fixed grooves 13 are also arranged relatively, which makes the force uniform and the support points relatively balanced.

[0031] The above design scheme can enable the product to achieve the advantages of stable connection and anti-falling.

[0032] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
