Description

Technical Field

[0001] The utility model belongs to the technical field of stone dry hanging, and in particular relates to a self-locking dry hanging piece. Background Art

[0002] Stone dry hanging technology is a building exterior wall decoration method. Stone is fixed to the wall through metal hangers to form a beautiful exterior wall decoration effect. This technology has been developed in my country for many years and is currently in a mature stage. Stone dry hanging technology has the advantages of convenient construction, beautiful decorative effect, and strong durability. During the construction process, it is necessary to pay attention to key links such as the selection of hangers, cutting and fixing of stones. With the continuous innovation of technology, stone dry hanging technology will develop in a more convenient, more reliable, more efficient, and more environmentally friendly direction, providing better services for the construction industry.

[0003] The existing dry hanging process is to drill holes in the angle steel and fix it to the main keel with bolt assemblies, fix the main keel to the wall, and then use bolt assemblies to fix the dry hanging parts to the angle steel, and finally fix the stone to the dry hanging parts with dry hanging glue. The whole process needs to use bolt assemblies for fixing many times, which is cumbersome and inefficient. At the same time, the bolt assemblies are located between the stone and the keel. Due to the narrow distance between the stone and the keel, it is difficult to use tools to remove the bolt assemblies after the stone is damaged or the dry hanging parts are aged. Utility Model Content

[0004] In order to solve the above technical problems, the utility model designs a self-locking dry hanging piece, which can quickly carry out dry hanging of stones and is convenient for disassembling and replacing stones or dry hanging pieces.

[0005] A self-locking dry hanging part, characterized in that it includes an upper cover welded in a keel mounting groove, the upper cover is threadedly connected to the lower bottom of a hollow truncated cone-shaped bottom shell, an inner sleeve is arranged inside the bottom shell; three windows are equidistantly provided on the side wall of the inner sleeve, buckle steel balls are installed in the windows corresponding to the interference fit, and a spring is arranged in the inner sleeve on the buckle steel balls; a through hole is provided on the upper bottom surface of the bottom shell, a fixed locking rod is inserted into the through hole, and the outer end of the fixed locking rod is fixed with a buckle; a retracted annular groove is provided in the middle of the fixed locking rod.

[0006] An annular baffle is arranged at one end of the spring to press the three steel balls.

[0007] The fixed locking rod can pass through the buckle steel ball and clamp the buckle steel ball in the annular groove to connect it with the inner sleeve.

[0008] The beneficial effect of the utility model is as follows: compared with the prior art, the utility model welds the upper cover in the keel installation groove in sequence according to the design dry hanging installation requirements of the stone, and then uses a spring to install the inner sleeve together with the steel ball installed at the window in the bottom shell, and the bottom shell and the upper cover are screwed and connected, and then the fixed locking rod can be inserted through the through hole on the bottom surface of the bottom shell. During the insertion process, the spring supported between the upper cover and the steel ball is compressed to provide supporting force for the inner sleeve. Under the push of the cylindrical fixed locking rod, the steel ball moves outward in the window as the radius of the inner side wall of the bottom shell changes to expand the space between the three steel balls, so that the fixed locking rod can be inserted into the inner sleeve, and then no reinforcement operation is required. Under the support of the deformation rebound force of the spring, when the annular groove position of the fixed locking rod moves between the steel balls, the three steel balls clamp the annular groove to the inside, thereby realizing self-locking, and then the stone is bonded and fixed at the corresponding stone hole position on the buckle connected to the fixed locking rod, so as to realize the rapid dry hanging installation of the stone and improve the installation efficiency and installation stability. At the same time, when it is necessary to dismantle the dry hanging parts or stones, the bottom shell can be directly rotated to unscrew the threaded connection for quick disassembly, which is not affected by the distance between the stone and the keel.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Example 1: See Figures 1 to 3As shown, a self-locking dry hanging part includes an upper cover 2 welded in the installation groove of the keel 1 in sequence according to the dry hanging requirements, and the upper cover 2 is connected to the lower bottom thread of the hollow truncated cone bottom shell 3. The upper cover 2 and the bottom shell 3 can be quickly fastened or disassembled by rotating the thread; and the radius of the lower bottom surface of the hollow truncated cone bottom shell 3 is greater than the radius of the upper bottom surface;

[0018] A hollow cylindrical inner sleeve 4 is installed inside the bottom shell 3, and three square windows 401 are equidistantly provided on the side wall of the inner sleeve 4. Steel balls 5 are installed correspondingly in the windows 401. The diameter of the steel balls 5 is slightly larger than the side length of the square windows 401, so that the steel balls 5 are stuck in the windows 401 on the side wall of the inner sleeve 4. The steel balls 5 will move in the windows 401 only after being squeezed by force.

[0019] A spring 6 is also installed between the steel ball 5 on the inner sleeve 4 and the upper cover 2. A baffle 601 is set at one end of the spring 6 extending into the inner sleeve 4 to press on the three steel balls 5. The baffle 601 is an annular plate, and the inner radius of the annular plate is at least equal to the diameter of the fixed locking rod 7. A through hole is set on the bottom surface of the bottom shell 3, and the fixed locking rod 7 is inserted into the through hole. The outer end of the fixed locking rod 7 is fixed with a buckle 8; a retracted annular groove 701 is set in the middle of the fixed locking rod 7, and the buckle 8 is connected and fixed with the stone 9. The inner sleeve 4 is installed tightly against the inner wall of the bottom shell 3, and the diameter of the space formed by the three steel balls 5 is the same as the diameter of the annular groove 701.

[0020] During the insertion process of the fixed locking rod 7, the spring 6 is compressed to provide axial support force for the steel balls 5 and the inner sleeve 4. At the same time, the steel balls 5 are pushed outward by the push of the cylindrical fixed locking rod 7, so that the fixed locking rod 7 can pass through the three steel balls 5 and be inserted into the inner sleeve 4. When the fixed locking rod 7 is smoothly retracted to the position of the conical annular groove 701, the fixed locking rod 7 is no longer pushed forward, and the spring returns to its original state, so that the three steel balls 5 are clamped on the annular groove 701, thereby achieving self-locking and ensuring the stability of the dry hanging.

[0021] A buckle 8 is welded at the outer end of the fixed lock rod 7, and the buckle 8 is connected to the stone 9. The buckle 8 in this embodiment adopts a common U-shaped fastener, and the U-shaped fastener is bonded and fixed to the installation hole of the stone 9, thereby completing the dry hanging of the stone 9.

[0022] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all details in detail, nor do they limit the utility model to only the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
