[0002] Dry-hanging of building wall tiles is undoubtedly a crucial and technically demanding construction process. Traditional dry-hanging techniques involve complex steps, leading to high material and labor costs. In practice, simplified techniques have emerged, along with a large number of compatible fasteners. While these simplified techniques reduce costs, they significantly lower construction quality and pose serious safety hazards. The quality of the work largely depends on the skill of the technicians, requiring a high level of expertise, and doesn't necessarily reduce labor costs. To address this challenge, various new construction methods are constantly emerging.

[0003] A search revealed Chinese patent CN221399670U, which discloses "A Dry-Hanging Structure for Wall Tiles." In this structure, the dry-hanging panels are installed on a keel frame via columns. One end of each column has a stop bar. Each time the column is inserted through a through hole in the dry-hanging panel and the keel frame, the stop bar needs to be manually rotated. Similarly, when disassembling, the stop bar must be manually rotated until it is parallel to the column before the column can be pulled out. This type of "column" functions as a positioning pin, but its assembly and disassembly are cumbersome, and sometimes require two hands for quick and easy assembly and disassembly. Therefore, this application provides a dry-hanging panel positioning pin that is easy to assemble and disassemble to meet this requirement. Utility Model Content

[0004] The purpose of this application is to provide a dry-hanging panel positioning pin that is easy to disassemble and assemble, in order to solve the technical problem that the existing columns are relatively troublesome to disassemble and assemble, and sometimes require two hands to operate for quick disassembly and assembly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Reference Figure 1-3 The present invention discloses a positioning pin for a dry-hanging panel that is easy to assemble and disassemble, including a positioning pin 3. The positioning pin 3 is configured with an L-shaped structure and includes a straight section and a curved section. The straight section is provided with a straight groove 4, a first annular groove 5 and a second annular groove 6. The second annular groove 6 is located at the right end of the straight groove 4. The first annular groove 5 and the second annular groove 6 are both connected to the inner cavity of the straight groove 4. The distance between the first annular groove 5 and the second annular groove 6 is adapted to the distance between the through holes provided on the two upright plates 2 of the dry-hanging panel 1. Limiting blocks 12 are fixed in both through holes.

[0020] During installation, with the straight groove 4 facing upwards, insert one end of the positioning pin 3 into the through hole. The limiting block 12 in the through hole will move along the straight groove 4 until a set of limiting blocks 12 abuts against the inner wall of the second annular groove 6. At this point, the positioning pin 3 can no longer be moved. At this time, the two limiting blocks 12 are respectively located in the first annular groove 5 and the second annular groove 6. Then, rotate the positioning pin 3 (rotation angle greater than 30°) and release the positioning pin 3. The subsequent bending section will continue to drive the positioning pin 3 to rotate due to its own gravity. Finally, the positioning pin is as follows. Figure 1 As shown, the positioning pin 3 is blocked by the limiting block 12 and cannot be pulled out. When disassembling, you can pinch the curved section of the positioning pin 3 with your hand and rotate it 180°. At this time, the straight groove 4 faces upward, and then you can directly pull out the positioning pin 3. The disassembly and assembly of this positioning pin 3 is convenient and quick, and can be operated with one hand.

[0021] It should be noted that the size of the limiting block 12 is adapted to the first annular groove 5, the second annular groove 6 and the straight groove 4.

[0022] As a preferred embodiment of this example, Figure 4 As shown, the bottom end of the curved section is equipped with a movable head 8 via a movable column 9. A slider 10 is provided on the outer wall of the movable column 9. The bottom of the curved section is provided with a movable cavity adapted to the movable column 9 and a sliding groove adapted to the slider 10.

[0023] The curved end is equipped with a movable head 8, which can automatically enter and exit the movable cavity according to its own weight. According to the installation height of the straight section, the movable head 8 can automatically change its length and make its lower end contact the upper end of the dry hanging plate 1, which prevents the shaking of the positioning pin 3 and further enhances the stability of the pin.

[0024] As a preferred embodiment of this example, Figure 4 As shown, the bottom end of the movable head 8 is provided with a groove, and a magnetic block 7 is fixed in the groove.

[0025] The telescopic movable head 8 allows its lower end to fit tightly against the upper end of the dry-hanging plate 1, shortening the distance between the magnetic block 7 and the adsorption end of the hanging plate 1. Through the magnetic action of the magnetic block 7 and the dry-hanging plate 2, the positioning pin 3 is firmly positioned and is not prone to shaking (excessive shaking can easily cause wear and affect the installation accuracy of the components).

[0026] As a preferred embodiment of this example, Figure 4 As shown, a ball bearing 11 is provided at the bottom of the movable head 8.

[0027] The ball bearings 11 reduce friction between the lower end of the curved section and the dry-hanging plate 1 when the section rotates.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
