[0022] The following will Figures 1 to 2 describe the present utility model in detail.

[0023] Embodiment:

[0024] A waterproof hinge mechanism for a board. In some embodiments, as Figures 1 to 4 shown, it includes profile members 1 made of aluminum alloy symmetrically arranged up and down, and elastic hinge members. One end of the profile member 1 is provided with an installation groove 3 matching the existing board 2; the other end of the profile member 1 is provided with a hinge member matching structure cooperating with the elastic hinge member, and the two profile members 1 are connected by the hinge member matching structure and the elastic hinge member.

[0025] During use, the board 2 is installed in the installation groove 3 and fixed by adhesive; this device realizes the hinge function between the boards 2 through the hinge member matching structure and the elastic hinge member, and realizes the waterproof function through the elastic hinge member, and can effectively prevent rainwater from entering the inner side of the board 2 from the outside of the board 2 through the hinge joint between the boards 2.

[0026] In some embodiments, the elastic hinge member includes a strip-shaped main body 4, and limiting blocks 5 are provided at the upper and lower ends of the strip-shaped main body 4. The limiting blocks 5 are arranged on the outside of the strip-shaped main body 4, so that a buckling groove 6 is formed on the outside of the strip-shaped main body 4.

[0027] In some embodiments, the member matching structure includes a limiting groove 7 arranged inside the profile member 1 and matching the cross-sectional shape of the limiting block 5. The cross-sectional area of the limiting groove 7 is larger than the cross-sectional area of the limiting block 5; the limiting groove 7 is provided with an engaging groove 8 matching the strip-shaped main body 4 at one end far from the installation groove 3. The width of the engaging groove 8 is larger than the width of the strip-shaped main body 4, and one end of the engaging groove 8 communicates and extends to the outside of the profile member 1.

[0028] In some embodiments, an arc-shaped convex portion 9 is further provided at the middle position on the outside of the strip-shaped main body 4.

[0029] When the two plates 2 are arranged in parallel, the arc-shaped convex part 9 abuts between the upper and lower engagement grooves 8, and the limit blocks 5 and the strip-shaped main body 4 respectively abut against the inner sides of the limit groove 7 and the engagement groove 8 under the action of elasticity. At this time, it can prevent liquid (such as rainwater) from entering the inner side of the plate 2 through the hinge joint between the plates 2 from the outside of the plate 2. When the two plates 2 are bent inward, the fastening groove 6 tightly abuts against the outer side of the engagement groove 8 and the side wall of the limit groove 7 under the action of the elastic restoring force, achieving a better waterproof effect.

[0030] In some embodiments, a bending groove 10 is provided at a position on the inner side of the strip-shaped main body 4 corresponding to the arc-shaped convex part 9. When the plate 2 is bent, it helps the convex deformation of the arc-shaped convex part 9 and increases the waterproof effect.

[0031] In some embodiments, the elastic hinge member is made of rubber material.

[0032] In some embodiments, a weight-reducing space 11 is provided inside the profile member 1. It saves the production materials of the profile member 1 and reduces the production cost.

[0033] Device working principle:

[0034] In this device, the limit blocks 5 at both ends of the elastic hinge member are respectively arranged in the limit grooves 7 in different upper and lower profile members 1, the strip-shaped main body 4 is arranged in the engagement groove 8, and the arc-shaped convex part 9 abuts between the upper and lower engagement grooves 8.

[0035] As Figure 1 shown, when the two plates 2 are arranged in parallel, the arc-shaped convex part 9 abuts between the upper and lower engagement grooves 8, and the limit blocks 5 and the strip-shaped main body 4 respectively abut against the inner sides of the limit groove 7 and the engagement groove 8 under the action of elasticity. At this time, it can prevent liquid (such as rainwater) from entering the inner side of the plate 2 through the hinge joint between the plates 2 from the outside of the plate 2.

[0036] As Figure 2 shown, when the two plates 2 are bent inward, the fastening groove 6 tightly abuts against the outer side of the engagement groove 8 and the side wall of the limit groove 7 under the action of the elastic restoring force, achieving a better waterproof effect.

[0037] The above embodiments only represent the specific implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
