[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-5 As shown, a composite insulation board includes a body 1 and insulation nails 3;

[0026] A foldable mounting plate 2 is arranged on the main body 1, and a plurality of adjacent foldable mounting plates 2 are arranged to form a full circle for inserting the heat preservation nails 3;

[0027] The heat preservation nail 3 includes an expansion portion 32;

[0028] The foldable mounting plate 2 includes a stepped portion 23 and an arcuate elastic paddle 22 for connecting adjacent stepped portions 23 . The arcuate elastic paddle 22 is driven to bend and move along the direction of inserting the heat preservation nail 3 . In the bent state, the arcuate elastic paddle 22 presses against the expansion portion 32 .

[0029] Specifically, an insertion rod 11 is provided on the main body 1, and a groove for inserting the insertion rod 11 is provided on the adjacent surface of the other main body 1. The assembly of multiple main bodies 1 is achieved by inserting the insertion rod 11 and the groove. The foldable mounting plate 2 is located at the right-angle corner of the main body 1, and the insulation nail 3 is a hollow structure for inserting the anchor nail.

[0030] Furthermore, after a plurality of main bodies 1 are assembled on the wall, a plurality of foldable mounting plates 2 are enclosed into a whole circle, and a through-hole structure is formed in the center of the whole circle for the insulation nail 3 to be inserted, and an impact drill is used to drill a hole in the direction of the through-hole, and then the insulation nail 3 is inserted along the through-hole, and pressure is applied to the insulation nail 3 so that the expansion portion 32 of the insulation nail 3 is initially expanded, and at the same time, the insulation nail 3 presses the step portion 23, and the adjacent step portions 23 are close to each other, and the arc-shaped elastic paddle 22 is bent and deformed by the force and drives the step portion 23 to move in the direction of inserting the insulation nail 3, and the bent arc-shaped elastic paddle 22 and the expansion portion 32 are pressed against each other, so as to Figure 5 The state shown is used as a reference, and a plurality of bent arc-shaped elastic paddles 22 form a circular recessed structure, the insulation nail 3 is located at the center of the recessed structure, and finally the anchor nail is inserted into the middle of the insulation nail 3, and the anchor nail further expands the expansion part 32 from the inside.

[0031] In the above technology, through the design of the foldable mounting plate 2, pressure is applied to the insulation nail 3 during the insertion process of the insulation nail 3, so that the step portion 23 is pressed, and the adjacent step portions 23 are close to each other, and the arc-shaped elastic paddle 22 is bent and deformed under the force and drives the step portion 23 to move along the direction of inserting the insulation nail 3. The bent arc-shaped elastic paddle 22 and the expansion portion 32 press against each other to fix the insulation nail 3, and multiple bent arc-shaped elastic paddles 22 form a circular recessed structure, and the insulation nail 3 is located at the center of the recessed structure, which has a better anti-slip effect on the main body 1.

[0032] As an embodiment further provided by the present invention, the foldable mounting plate 2 further includes a vertical folding portion 21 disposed on the stepped portion 23 , and the vertical folding portion 21 is squeezed and bent by the heat-insulating nails 3 .

[0033] Specifically, multiple vertical folding parts 21 are squeezed and bent by the insulation nail 3 and approach each other, so that the vertical folding parts 21 shrink along the insertion direction of the insulation nail 3, and at the same time form a circular concave structure after bending, and the insulation nail 3 is located in the center of the concave, which further prevents it from falling off.

[0034] As another embodiment further provided by the present invention, a plurality of vertical folded portions 21 enclose a port, and the port has a bucket-shaped structure.

[0035] Specifically, the bucket-shaped structure of the port allows the insulation nail 3 to be automatically centered during the insertion process to avoid deflection, and the vertical folded portion 21 has a certain depth when not inserted, which can better provide space for the insulation nail 3 to be inserted. The conventional practice is to drill a hole in the main body 1. At this time, only a small section of the insulation nail 3 is located in the hole when the insulation nail 3 is inserted, which is relatively unstable. Manual stabilization is required when the anchor nail is subsequently driven in, while the vertical folded portion 21 provides a deeper insertion channel, which is beneficial to the stability of the insulation nail 3.

[0036] As another embodiment further provided by the present invention, a plurality of rotating rods 33 are rotatably provided on the expansion portion 32 , and the rotating rods 33 are driven to flip and be perpendicular to the outer wall of the expansion portion 32 .

[0037] Specifically, a protrusion is provided at the end of the rotating rod 33, and the protrusion is located outside the expansion part 32 in the default state. During the process of inserting the thermal insulation nail 3, the protrusion of the rotating rod 33 contacts the wall, and is flipped and perpendicular to the outer wall of the expansion part 32 under the reaction force of the wall. Then the step parts 23 are pressed and close to each other, and the arc-shaped elastic paddle 22 is pressed and bent and pressed against the expansion part 32. At the same time, the arc-shaped elastic paddle 22 presses and fixes the rotating rod 33.

[0038] As another embodiment further provided by the present invention, the heat-insulating nail 3 further includes an umbrella-shaped top 31 arranged at the top of the expansion portion 32, and the umbrella-shaped top 31 includes an upper arc surface and a lower arc surface.

[0039] Specifically, the upper arc surface is convex in the default state, bends downward when under pressure, and becomes concave under the action of its own deformation potential energy. At this time, the upper arc surface is tightly attached to the lower arc surface, and is tightly attached to the circular concave structure surrounded by multiple vertical folding parts 21, making it difficult to pull out the umbrella-shaped top 31, and multiple openings are provided on the upper arc surface and the lower arc surface to allow air to circulate between the upper arc surface and the lower arc surface, thereby avoiding inflation inside the umbrella-shaped top 31, which makes it inconvenient to knock.

[0040] Working principle: after multiple bodies 1 are assembled on the wall, multiple foldable mounting plates 2 are enclosed into a full circle, and the bucket-shaped structure at the end of the vertical folding portion 21 allows the insulation nail 3 to be automatically centered during the insertion process to avoid deflection, and the vertical folding portion 21 has a certain depth when not inserted, which can better allow the insulation nail 3 to be inserted, and a through-hole structure is formed in the center of the full circle for the insulation nail 3 to be plugged in. An impact drill is used to drill a hole in the through-hole direction, and then the insulation nail 3 is inserted along the through-hole, and pressure is applied to the insulation nail 3 to cause the expansion portion 32 of the insulation nail 3 to expand initially, and the protrusion of the rotating rod 33 contacts the wall, and is flipped over and perpendicular to the outer wall of the expansion portion 32 under the reaction force of the wall, and multiple vertical folding portions 21 are The heat preservation nail 3 is squeezed and bent and approaches each other, so that the vertical folded portion 21 shrinks along the insertion direction of the heat preservation nail 3, and a circular concave structure is formed after bending, and the heat preservation nail 3 is located at the center of the concave, and the upper arc surface is convex in the default state, and bends downward after being subjected to pressure, and is concave under the action of its own deformation potential energy. At this time, the upper arc surface is tightly attached to the lower arc surface, and is tightly attached to the circular concave structure surrounded by multiple vertical folded portions 21, so that the umbrella-shaped top 31 is difficult to pull out, and then the step portion 23 is pressed, and the adjacent step portions 23 are close to each other, and the arc-shaped elastic paddle 22 is bent and deformed by force and drives the step portion 23 to move along the direction of inserting the heat preservation nail 3, and the bent arc-shaped elastic paddle 22 and the expansion portion 32 are pressed against each other, so as to prevent the heat preservation nail 3 from being inserted into the center of the concave structure. Figure 5 The state shown is used as a reference, and the arc-shaped elastic paddle 22 presses and fixes the rotating rod 33.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
