Description

Technical Field

[0001] The utility model relates to the technical field of metal house systems, in particular to a metal roof panel fixing fastener. Background Art

[0002] At present, the roofs of many large buildings are paved with metal roof panels, which are used to waterproof and sun-proof the roofs of buildings. The two ends of each metal roof panel overlap with the adjacent metal roof panels to form an overlap. The core structure of the vertical lock seam roof system, also known as the point support roof system, is a special plate-shaped metal plate based on the vertical edge bite design. This design is mainly aimed at the large-span self-supporting close-fitting installation system. The connection method of the plate is to use its unique aluminum alloy support. The vertical edge bite of the plate and the plate forms a close connection. The bite process of this plate does not require manpower and is completely completed by machinery automatically.

[0003] At present, a Chinese patent discloses a standing seam metal roof panel fixing fastener, and its publication number is CN213115235U. In the disclosed technical solution, when the panel is buckled on the fixing fastener, the metal roof panel is prone to loosening and sliding over time. Therefore, we propose a metal roof panel fixing fastener to solve this problem. Utility Model Content

[0007] Two cross bars are arranged through the inner side of the through opening.

[0008] The fastener head, the bottom of the fastener head and the top of the fastener facade are integrally formed, holes are opened on both sides and the top of the fastener head surface, a rubber head is slidably arranged on the inside of the hole, one end of the rubber head is fixedly connected to a pull wire, and the bottom end of the pull wire is fixedly connected to the surface of the cross bar.

[0009] As a further improvement of the above solution, both ends of the cross bar pass through the through opening and extend to the outside of the fastener facade.

[0010] As a further improvement of the above solution, three fixing plates arranged in a triangle are fixedly connected to the inner side of the fastener head, and small holes for the pull wire to pass through are opened on the surface of the fixing plates.

[0011] As a further improvement of the above solution, the fastener head consists of three arc-shaped heads.

[0012] As a further improvement of the above solution, one end of the rubber head is fixedly connected to a return spring, and one end of the return spring is fixedly connected to the surface of the fixed plate.

[0013] As a further improvement of the above solution, a through hole for the pull wire to pass through is provided at the connection between the fastener head and the fastener facade.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model uses a pull wire and a rubber head. After the metal roof panel is slidably installed with a fixing fastener, the pull wire can make the rubber head extend out, thereby increasing the friction force and preventing the metal roof panel from loosening and sliding after installation.

[0016] 2. The utility model uses the pull wire and the cross bar in coordination, so that after the cross bar is pulled, the pull wire can retract the rubber head, which will not affect the installation of the metal roof panel. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Please combine Figure 1-3A metal roof panel fixing fastener of the present embodiment includes a fastener bottom surface 1, a fastener vertical surface 4, two cross bars 11 and a fastener head 7. Both sides of the fastener bottom surface 1 are provided with mounting holes 2, and connecting bolts 3 are installed on the inner side of the mounting holes 2. The fixing fastener can be installed through the connecting bolts 3.

[0024] The fastener vertical surface 4 is integrally formed with the top of the fastener bottom surface 1 , and interconnected through-openings 5 ​​are provided on the front and rear sides of the surface of the fastener vertical surface 4 , and vertical grooves 6 interconnected with the through-openings 5 ​​are provided on both sides of the interior of the fastener vertical surface 4 .
