[0005] However, since the curved surface plate is in a certain regular wave shape, and the surface of the traditional bolt is a plane, when the traditional bolt is used to fix the curved surface plate, the contact area between the bolt and the curved surface plate is small, and the bolt cannot be tightly attached to the curved surface plate, which affects the fixing degree and sealing property of the two, and the use effect is not ideal. INVENTION CONTENTS

[0006] The utility model aims at solving the above-mentioned problems and provides a convex bolt for curved surface board installation, which can stably install and fix the curved surface plate at the wave trough position, has larger contact area and friction, and is more stable in use.

[0007] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a convex bolt for curved surface board installation, which comprises a hexagonal head and a threaded rod on one side of the hexagonal head, an integral flange plate is arranged between the hexagonal head and the threaded rod, and an arc convex surface is arranged on the side of the flange plate away from the hexagonal head.

[0008] Preferably, the arc convex surface is attached to the wave trough of the curved surface plate, and the threaded rod extends downward through the curved surface plate.

[0009] Preferably, a matched locking nut is further arranged on the threaded rod, and the locking nut is arranged below the arc plate.

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

[0011] Preferably, a plurality of annular grooves are further arranged on the arc convex surface, and annular rubber rings are arranged in the annular grooves.

[0012] Preferably, the rubber rings protrude from the surface of the arc grooves.

[0013] The utility model discloses a convex bolt for the installation of curved panel, including hexagonal head and hexagonal head one side's threaded rod, be equipped with the integral flange between hexagonal head and threaded rod, the flange is equipped with arc convex surface on the side away from hexagonal head, arc convex surface sticks to the trough of curved panel, threaded rod passes curved panel and extends downward, compared with prior art, the convex bolt for the installation of curved panel has the beneficial effects of being able to stably install and fix curved panel, having greater contact area and friction, and being strong in sealing property after installation, and avoiding immersion.

[0020] Now the utility model will be further explained in detail in conjunction with the drawings. The drawing is simplified schematic diagram, just with the schematic way of the basic structure of the utility model, therefore it just shows the constitution related to the utility model.

[0021] Please refer to Figures 1-4 A convex bolt for the installation of curved panel, including hexagonal head 1 and hexagonal head 1 one side's threaded rod 3, the integral flange 2 is equipped between hexagonal head 1 and threaded rod 3, the flange 2 is equipped with arc convex surface 4 on the side away from hexagonal head 1.

[0022] Wherein hexagonal head 1, flange 2 and threaded rod 3 are all arranged on the same axis, and are integrally cast in the mold, and the circumference of the threaded rod 3 is provided with external threads.

[0023] Please refer againFigures 1-2 The arc convex surface 4 is attached to the wave trough of the curved panel 6, and the threaded rod 3 extends downward through the curved panel 6.

[0024] Since the curved panel 6 is in an arc wave shape, the wave trough of the curved panel 6 is in an arc concave shape, and the wave trough of the curved panel 6 is attached to the arc convex surface 4, the threaded rod 3 extends downward through the curved panel 6 during use, and the downward extending threaded rod 3 cooperates with the locking nut 5.

[0025] During use, the threaded rod 3 is first passed through the wave trough of the curved panel 6, so that the arc convex surface 4 is attached to the wave trough, and then the locking nut 5 is picked up and screwed from the end of the threaded rod 2, so that the locking nut 5 is squeezed against the curved panel 6, thereby achieving the fixing effect.

[0026] Since the arc convex surface 4 is attached to the wave trough of the curved panel 6, the contact area between the two can be increased, and the fixing stability of the curved panel can be improved; at the same time, the attachment of the arc convex surface 4 to the curved panel can improve the sealing of the bolt and the curved panel, and prevent the occurrence of water immersion.

[0027] As a second embodiment of the present application, please refer to Figure 5 The arc convex surface 4 is further provided with a plurality of annular grooves 41, and an annular rubber ring (not shown in the figure) is arranged in the annular groove 41, wherein the annular rubber ring can be fixed in the annular groove 41 by glue; in addition, the rubber ring protrudes from the surface of the arc concave groove 41, and the protruding height is preferably 2mm.

[0028] Since the rubber ring has a certain elastic deformation capacity, and the rubber ring protrudes from the annular groove 41, the arc convex surface 4 first contacts the wave trough of the curved panel 6 through the rubber strip; as the locking nut 5 is tightened and fixed, the rubber strip can be gradually squeezed, and finally the arc convex surface 4 and the rubber strip both contact the wave trough of the curved panel 6, thereby greatly increasing the contact area and the friction force, and ensuring the fixing and installation effect.

[0029] In addition, since the rubber ring is also annular and surrounds the threaded rod 3, the water immersion effect can be further improved, the sealing performance of the curved panel 6 and the arc convex surface 4 can be ensured, and the practicability is high.

[0030] The convex bolt in the present application is used for an arc specific shape, has a unique use scene, and has a stable installation and fixing capacity that cannot be achieved by traditional bolts.

[0031] Obviously, the above embodiments are only examples for clearly illustrating, and are not a limitation on the embodiments. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
