[0001] The utility model relates to the technical field of heat preservation board installation, in particular to a heat preservation board fixing structure for a building exterior wall. Background Art

[0002] In the northern region, the exterior walls of buildings need to be thermally insulated. The following two solutions are usually used for wall thermal insulation design: The first solution is to fill the interior of the blocks with thermal insulation materials. This solution is simple and easy to implement, and has good fire resistance, but it often fails to meet the requirements in areas with high thermal insulation requirements; the second solution is to not fill the interior of the blocks with thermal insulation materials, and install thermal insulation boards on the outside of the walls after the external filling wall masonry is completed.

[0003] When installing the insulation board in the prior art, holes are usually drilled in the wall first, then the expansion bolts are connected to the wall, and then the insulation board is connected to the expansion bolts through external bolts, so that the insulation board and the wall are connected together. However, after the bolts are connected, the insulation board is in the external space and the insulation board will vibrate due to the wind. The insulation board is prone to bolt detachment during long-term vibration, causing the insulation board to fall off. To this end, we provide a fixing structure for the building exterior wall insulation board to solve the above problems. Utility Model Content

[0016] 1. The utility model cooperates the spring telescopic plug rod installed in the extension bolt and the plug hole opened on the inner ring surface of the tightening bolt. As the meshing length of the tightening bolt and the extension bolt increases, the extension bolt gradually enters the tightening bolt. After the right end of the long column contacts the right inner wall of the tightening bolt, the tightening bolt gradually pushes the long column to compress the positioning spring. As the spring telescopic plug rod contacts the conical surface of the concave annular groove, it gradually pushes the spring telescopic plug rod to move outside the tightening bolt.

After the spring telescopic plug rod coincides with the plug hole, the spring telescopic plug rod is inserted into the plug hole, so that the tightening bolt and the extension bolt will no longer rotate out of position, so that when the insulation board is vibrated, the tightening bolt will no longer be separated from the extension bolt.

[0017] 2. The utility model has a through hole at the right end of the tightening bolt. When the insulation board needs to be disassembled, since the tightening bolt cannot rotate relative to the extension bolt, the long column compression positioning spring is pushed through the through hole to move the spring telescopic plug rod to the next concave ring groove. The push spring pushes the spring telescopic plug rod into the extension bolt, so that the extension bolt can rotate relative to the tightening bolt, and the tightening bolt and the extension bolt can be separated to disassemble the insulation board.

A plurality of spring telescopic plug rods 7 are slidably inserted on the inner ring surface of the extension bolt 3 and inside each concave ring groove 6, and an end groove 8 is provided on the outer ring surface of the right end of the long column 5, and the end groove 8 is located on the right side of the concave ring groove 6. One end of the spring telescopic plug rod 7 located inside the extension bolt 3 is elastically connected to the inner wall of the extension bolt 3 through a push spring 9, and the push spring 9 has a push spring The spring telescopic plug rod 7 tends to move into the extension bolt 3. The inner walls on both sides of the concave annular groove 6 are conical surfaces, and multiple concave annular grooves 6 are evenly distributed at equal distances. The spring telescopic plug rod 7 can gradually compress the push spring 9 by moving on the conical surface of the concave annular groove 6. The inner ring surface of the tightening bolt 4 is provided with multiple insertion holes 10. The inner diameter of the insertion hole 10 is equal to the small diameter telescopic end of the spring telescopic plug rod 7. The end of the insertion hole 10 close to the axis of the tightening bolt 4 is inverted with an oblique angle. Before the spring telescopic plug rod 7 coincides with the insertion hole 10, the spring telescopic plug rod 7 is in a compressed state. After the sockets 10 overlap, the spring telescopic rod 7 is inserted into the socket 10, and the left side surface of the long column 5 is elastically connected to the left inner wall of the wall bolt 2 through the positioning spring 18. A through hole 16 is opened at the right end of the tightening bolt 4. The inner diameter of the through hole 16 is smaller than the outer diameter of the right end of the long column 5. The long column 5 can be pushed to move through the through hole 16, and the long column 5 can continue to be pushed to compress the positioning spring 18, so that the spring telescopic rod 7 can be moved to the next concave ring groove 6, so that the spring telescopic rod 7 can be retracted into the extension bolt 3 again, and the spring telescopic rod 7 on the far right is inserted into the end groove 8.

[0026] A fixed inner ring 11 is fixedly inserted inside the wall bolt 2, and the long column 5 is slidably inserted inside the fixed inner ring 11.

As the spring telescopic plug rod 7 contacts the conical surface of the concave ring groove 6, it gradually pushes the spring telescopic plug rod 7 to move outside the tightening bolt 4. At the same time, the long column 5 drives the conical surface of the push groove 14 to push the short rod 15 to push the top plate 13 out of the wall bolt 2. The top plate 13 can ensure that the wall bolt 2 will not rotate relative to the wall by tightening the inner hole of the wall, and ensure that the wall bolt 2 will not detach from the wall. Before the spring telescopic plug rod 7 coincides with the socket 10, The spring telescopic plug rod 7 is in a compressed state. After the spring telescopic plug rod 7 coincides with the insertion hole 10, the spring telescopic plug rod 7 is inserted into the insertion hole 10, so that the tightening bolt 4 and the extension bolt 3 will no longer rotate out of position, so that when the insulation board is vibrated, the tightening bolt 4 will no longer be separated from the extension bolt 3. When the insulation board needs to be disassembled, since the tightening bolt 4 cannot rotate relative to the extension bolt 3, the long column 5 is pushed through the through hole 16 to compress the positioning spring 18, so that the spring telescopic plug rod 7 moves to the next concave ring groove 6, and the push spring 9 pushes the spring telescopic plug rod 7 into the extension bolt 3, so that the extension bolt 3 can rotate relative to the tightening bolt 4, and the tightening bolt 4 can be separated from the extension bolt 3 to disassemble the insulation board.
