[0008] Preferably, the arc-shaped concave surface is attached to the wave crest of the curved panel, and the threaded rod extends downward through the curved panel.

[0009] Preferably, it further comprises a locking nut, and the locking nut is matched with the threaded rod.

[0010] Preferably, the hexagonal head, the flange plate and the threaded rod are arranged on the same axis.

[0011] Preferably, a plurality of parallel strip-shaped grooves are arranged on the arc-shaped concave surface, and fixed rubber strips are arranged in the strip-shaped grooves.

[0012] Preferably, the surface of the rubber strip protrudes from the surface of the arc-shaped concave surface.

[0013] The utility model discloses a concave bolt for curved panel installation, including hexagonal head and hexagonal head one side's threaded rod, the hexagonal head and threaded rod between locate the integral flange, the flange is located in the side away from hexagonal head and is equipped with arc concave surface, the arc concave surface sticks to the wave crest of curved panel, the threaded rod passes through curved panel and extends downward, compared with prior art, this concave bolt for curved panel installation has the stable installation and fixing of curved panel when using, and has greater contact area and friction, and the beneficial effect of using more stably.

[0022] Now the utility model will be further explained in detail in combination with the drawings. The drawing is the simplified schematic diagram, and only the basic structure of the utility model is schematically shown, therefore it only shows the constitution related to the utility model.

[0023] Please refer to Figures 1-4The utility model provides a concave bolt for curved panel installation, including hexagonal head 1 and the threaded rod 2 of one side of hexagonal head 1, be equipped with integral flange 3 between hexagonal head 1 and threaded rod 2, the arc concave 4 is equipped with in the side away from hexagonal head 1 of flange 3.

[0024] Wherein, hexagonal head 1, flange 3 with threaded rod 2 are all arranged on same axis, and hexagonal head 1, flange 3 with threaded rod 2 are integrally cast, wherein the circumference of threaded rod 2 is provided with external thread.

[0025] Please refer to Figures 1-2 The arc concave 4 is attached to the wave crest of curved panel 6, and the threaded rod 2 extends downward through the curved panel 6.

[0026] Since the curved panel 6 is arc-shaped, the wave crest surface of the curved panel 6 is arc-shaped, and the wave crest of the curved panel 6 is attached to the arc concave 4. During use, the threaded rod 2 extends downward through the curved panel 6 and cooperates with the screw nut 5.

[0027] During use, the threaded rod 2 is first passed through the wave crest of the curved panel 6, so that the surface of the arc concave 4 is attached to the arc-shaped wave crest. Then the locking nut 5 is picked up and tightened from the end of the threaded rod 2, so that the locking nut 5 is tightly pressed against the curved panel 6, thereby achieving the fixing effect.

[0028] Since the arc concave 4 is attached to the wave crest of the curved panel 6, the contact area between the two can be increased, and the stability of the curved panel can be improved. At the same time, the attachment of the arc concave 4 to the curved panel 6 can improve the sealing performance of the bolt and the curved panel, thereby avoiding the phenomenon of water immersion.

[0029] As a second embodiment of the utility model, please refer to Figures 5-7 The arc concave 4 is provided with a plurality of parallel strip-shaped grooves 41, and the strip-shaped grooves 41 are provided with fixed rubber strips 42, wherein the surface of the rubber strip 42 extends out of the surface of the arc concave 4.

[0030] The height of the rubber strip 42 extending out of the surface of the arc concave 4 is 1-2 mm, preferably 2 mm.

[0031] Since the rubber strip 42 has a certain elastic deformation capacity, and the rubber strip 42 extends out of the surface of the arc concave 4, the arc concave 4 first contacts the wave crest of the curved panel 6 through the rubber strip 42. With the tightening of the locking nut 5, the rubber strip 42 can be gradually pressed, and finally the arc concave 4 and the rubber strip 42 both contact the wave crest of the curved panel 6, thereby greatly increasing the contact area and the friction force and ensuring the fixing and installation effect.

[0032] The concave bolt in the utility model is used for arc-shaped specific shapes, has a unique use scene, and has a stable installation and fixing capacity that cannot be achieved by traditional bolts, and is practical.

[0033] Obviously, the above embodiments are only examples for the purpose of clarity, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can also be made by those of ordinary skill in the art. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
