Description

Technical Field

[0001] This utility model belongs to the field of curtain wall installation components, and in particular relates to a suspension spring pin component. Background Technology

[0002] The installation of an open-type metal panel curtain wall involves first hanging the metal panels onto the keel, and then connecting the metal panels and the keel using fasteners. To increase the stability of the metal panels, through holes are made between the top and bottom surfaces of the metal panels. Pins are then inserted through the corresponding through holes on the top and bottom surfaces of adjacent metal panels to improve the stability between the metal panels.

[0003] Currently, the pins inserted into the through holes of adjacent metal panels are installed by their own weight. Under long-term wind loads or other external forces, they may loosen or even fall off. Utility Model Content

[0004] The purpose of this utility model is to provide a suspension spring pin component to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model for a suspension spring pin component is as follows:

[0006] A hovering spring pin component includes a housing mounted on a metal panel, a pin inserted into the housing, and a movable connection between the pin and a mounting cylinder. An elastic element is located inside the housing, and the pin engages with the housing via the elastic element. The pin includes a pin shank and a pin cap, the pin cap being movable to the housing. The pin shank is polygonal, and the bottom surface of the mounting cylinder has a polygonal through hole adapted to the pin shank. The bottom surface of the pin shank has a tool hole adapted to an operating tool.

[0007] Furthermore, the housing includes a sleeve, a top plate on the top surface of the sleeve, and a bottom plate on the bottom surface of the sleeve, with a polygonal through hole on the bottom plate. An elastic element is disposed inside the sleeve between the top plate and the pin head of the pin.

[0008] Furthermore, the elastic element is a spring.

[0009] Furthermore, mounting holes are provided on the top plate. A limiting rod is vertically provided on the top surface of the pin cap, and a limiting block is provided on the top surface of the limiting rod. The limiting rod and the mounting hole are movably connected.

[0010] The suspension spring pin component of this utility model has the following advantages:

[0011] 1. This utility model provides a pin and an elastic element inside the housing. The elastic element can apply a pushing force to the pin, making the pin more stable on the housing and preventing the pin from loosening and falling off the metal panel, thereby further improving the connection stability of the pin to adjacent metal panel parts.

[0012] 2. The pins in this utility model can be suspended inside the sleeve, making the installation, maintenance, and replacement of metal panel curtain walls more convenient and improving construction efficiency. Attached Figure Description

[0019] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a suspension spring pin component of this utility model.

[0020] like Figures 1 to 4 As shown, this utility model discloses a suspension spring pin component, including a cover disposed on a metal panel 13, a pin inserted into the cover, and a movable connection between the pin and the mounting sleeve. An elastic element is located inside the cover, and the pin engages with the cover via the elastic element. The elastic element applies a pushing force to the pin, allowing it to be inserted into a corresponding through hole in an adjacent metal panel 13, thus connecting the adjacent panels. The external force applied to the pin by the elastic element makes the pin more stable on the cover, preventing it from loosening or falling off the metal panel 13, further improving the connection stability of the pin to the adjacent metal panels 13.

[0021] like Figure 4As shown, for ease of understanding, the metal panels 13 used for installing the curtain wall are hung on the wall joists 12, and the metal panels 13 and the joists 12 are fixedly connected by connectors (bolts and nuts, which are existing technology and will not be elaborated on here). Corresponding through holes are opened between the top and bottom surfaces of each metal panel 13. This pin component can be fixed (welded) to the inner bottom surface of the metal panel 13, and the pin in this pin component coincides with the through hole of the metal panel 13 so that the pin passes through the through hole.

[0022] Specifically, the pin includes a pin rod 5 and a pin cap 7, with the pin cap 7 being movable from the housing. The pin rod 5 is polygonal. A polygonal through-hole adapted to the pin rod 5 is also formed on the bottom surface of the mounting cylinder. The polygonal pin rod 5 and the polygonal through-hole form a fit. When the angle between the pin rod 5 and the polygonal through-hole is inconsistent, the pin rod 5 will stop inside the housing, thus suspending the pin within the housing. When the angle between the pin rod 5 and the polygonal through-hole coincides, the pin rod 5 pops out from the polygonal through-hole under the action of an elastic element, and then inserts into the corresponding through-hole of the adjacent metal panel 13, connecting the adjacent metal panels 13. To facilitate operation of the pin inside the housing, a tool hole 11 adapted to the operating tool is formed on the bottom surface of the pin rod 5. Insert the tool corresponding to tool hole 11 into tool hole 11 and rotate pin rod 5. Pin rod 5 drives pin head 7 to rotate together. When pin rod 5 rotates to coincide with the polygonal through hole of the cover, the pin will pop out of the cover under the action of the elastic element. When the pin needs to be retracted into the cover, insert the tool into tool hole 11 and push the pin into the cover. After the pin is fully inserted into the cover, rotate the pin to change the angle between the pin and the polygonal through hole. This pin component uses suspension technology to make the installation, maintenance and replacement of metal panel curtain walls more convenient and greatly improve construction efficiency.

[0023] Specifically, in this embodiment, the polygonal through hole is preferably a waist hole 10, and the pin rod 5 can be set along with the polygonal through hole. Furthermore, in this embodiment, the elastic element is preferably a spring 8, and the spring 8 is made of stainless steel. Of course, a spring sheet can also be used, and no further restrictions are imposed here.

[0024] like Figure 1As shown, the housing includes a sleeve 1, a top plate 2 on the top surface of the sleeve 1, and a bottom plate 3 on the bottom surface of the sleeve 1. A polygonal through hole is opened on the bottom plate 3. An elastic element is disposed inside the sleeve 1 between the top plate 2 and the pin head 7 of the pin. The top plate 2 and the top surface are welded to the sleeve 1, and the pin head 7 of the pin is movably disposed inside the sleeve 1 (i.e., the pin head 7 can slide and rotate inside the sleeve 1). The connection between this pin component and the metal panel 13 is achieved by welding the sleeve 1 to the inner bottom surface of the metal panel 13, so that the pin corresponds to the through hole on the metal panel 13. Among them, the spring 8 for applying a pushing force to the pin is sleeved on the limiting rod 4. The limiting rod 4 can limit and guide the spring 8 to prevent the spring 8 from bending.

[0025] Preferably, a mounting hole 9 is provided on the top plate 2. A limiting rod 4 is vertically provided on the top surface of the pin cap 7, and a limiting block 6 is provided on the top surface of the limiting rod 4. The limiting rod 4 and the mounting hole 9 are movably connected. When the pin rod 5 rotates, the limiting rod 4 on the pin cap 7 and the limiting block 6 on the limiting rod 4 also rotate and move with the pin rod 5. The limiting rod 4 increases the stability of the pin rod 5 relative to the sleeve 1 and improves the connection stability and reliability of the pin rod 5 to the adjacent metal panel 13.

[0026] Instructions for use: Weld this pin component onto the metal panel 13, then insert a tool into the tool hole 11 on the bottom surface of the pin rod 5. Rotate the pin rod 5 with the tool, and the pin rod 5 will drive the limiting rod 4 and the limiting block 6 to rotate through the pin cap 7. When the pin rod 5 rotates to coincide with the polygonal through hole of the upper base plate 3 of the sleeve 1, the elastic element pushes the pin rod 5 downward, so that the pin rod 5 is inserted into the through hole of the adjacent metal panel 13 to complete the connection of the metal panel 13.
