[0018] In order to better understand the purpose, structure and function of the utility model, below, combining with the drawings, the utility model a thermal insulation outer wall's anchor bolt component is further described in detail.

[0019] As Figures 1 to 4 Shown, the utility model discloses a thermal insulation outer wall's anchor bolt component, including the sleeve 1 that can be inserted into the wall body borehole, the fixed rod 2 that can be inserted into the sleeve 1, and the compression ring 3 of sleeveing in fixed rod 2 on. When using, insert the sleeve 1 into the borehole of wall body, then use fixed rod 2 and insert into the sleeve 1, when fixed rod 2 inserts into the sleeve 1, sleeve 1 expands and forms the friction between the borehole, so that fixed rod 2 and compression ring 3 will be fixed in the wall body through the sleeve 1 of thermal insulation outer wall.

[0020] As preferred, a plurality of mounting holes 4 are arranged on the outer wall of the sleeve 1 along the axial direction thereof, each mounting hole 4 is provided with a fixing assembly, and each fixing assembly cooperates with the fixing rod 2. By arranging the fixing assembly, after the fixing rod 2 is inserted into the sleeve 1, the fixing rod 2 cooperates with the fixing assembly, the fixing assembly can be inlaid into the wall body, thereby increasing the stability of the anchor bolt assembly relative to the wall body. Specifically, the fixing assembly comprises a first tab 5 arranged on the top surface of the mounting hole 4, the bottom end of the first tab 5 is arranged obliquely towards the center of the sleeve 1, and a first limiting piece 6 extends outwardly from the bottom surface of the outer wall of the first tab 5, and the first limiting piece 6 and the first tab 5 are arranged vertically. When the fixing rod 2 is inserted into the sleeve 1, the conical guide head on the bottom surface of the fixing rod 2 causes the first tab 5 to elastically expand outwardly, and the first limiting piece 6 arranged on the first tab 5 also moves outwardly, the first limiting piece 6 moves outwardly and contacts the wall body, and the first limiting piece 6 that moves outwardly extrudes and damages the wall body and is inlaid into the wall body, thereby increasing the stability of the sleeve 1 relative to the wall body through the first tab 5 and the first limiting piece 6. It should be noted that the first limiting piece 6 and the first tab 5 are arranged vertically, and the first tab 5 and the sleeve 1 can make the sleeve 1 have better pull-out capacity under the action of the first limiting piece 6.

[0021] As a further improvement, a second limiting piece 7 is arranged between the top surface of the first limiting piece 6 and the outer wall of the first tab 5. The thickness of the second limiting piece 7 is smaller than the width of the first limiting piece 6, when the first tab 5 drives the first limiting piece 6 to move outwardly of the sleeve 1, the second limiting piece 7 arranged on the first tab 5 also moves and is inlaid into the wall body, thereby preventing the sleeve 1 from rotating and further improving the stability of the sleeve 1 relative to the wall body.

[0022] In the embodiment, the fixing rod 2 comprises a rod cap 23, a light rod 21 and a threaded rod 22, the light rod 21 is arranged on the bottom surface of the rod cap 23, the threaded rod 22 is arranged on the bottom surface of the light rod 21, the bottom surface of the threaded rod 22 is a conical guide head, and the threaded rod 22 is threadedly connected with the sleeve 1. In order to prevent the sleeve 1 from rotating in the hole drilled in the wall body when the fixing rod 2 is screwed into the sleeve 1, a plurality of protrusions 9 are arranged on the outer wall of the sleeve 1 along the circumferential direction thereof. When the sleeve 1 is inserted into the hole, the protrusions 9 on the outer wall of the sleeve 1 generate friction with the inner wall of the hole, thereby preventing the sleeve 1 from rotating in the hole.

[0023] As Figure 3As shown, the inner wall bottom surface of the first dial 5 is provided with a positioning block 8. The top corner of the positioning block 8 is arranged towards the axis of the sleeve 1. When the fixing rod 2 is screwed into the sleeve 1, the threads on the threaded rod 22 on the fixing rod 2 will cooperate with the top edge of the positioning block 8 (i.e. the top edge of the positioning block 8 will be inserted into the thread gap of the threaded rod 22) without rotating the fixing rod 2, thereby preventing relative displacement between the fixing rod 2 and the sleeve 1.

[0024] Meanwhile, in order to prevent the fixing rod 2 from rotating relative to the sleeve 1, the inner wall of the sleeve 1 above the highest mounting hole 4 is provided with a plurality of second dials 10, and each second dial 10 is distributed in a circumferential direction of the sleeve 1. The light rod 21 is provided with a plurality of limiting grooves 11 along the circumferential direction. When the fixing rod 2 is installed in the sleeve 1 and the lowest end of the light rod 21 enters the sleeve 1, the limiting grooves 11 on the light rod 21 will dial each second dial 10, and when the fixing rod 2 stops rotating, the second dial 10 will be clamped into the corresponding limiting groove 11 at this time, thereby preventing the fixing rod 2 from rotating in the reverse direction.

[0025] Method for use: insert the sleeve 1 into the drill hole of the wall, then insert the fixing rod 2 into the sleeve 1, then use a tool to align the rod cap 23 at the top end of the fixing rod 2, rotate the fixing rod 2 using the tool, and the fixing rod 2 is screwed into the sleeve 1 through the threaded rod 22 thereon, and during the screwing process, the tapered guide head of the fixing rod 2 will push the first dial 5 on each positioning assembly to rotate outward, and the first limiting piece 6 and the second limiting piece 7 arranged on the first dial 5 move outward and are pressed against the wall to be inserted into the wall, thereby increasing the stability of the sleeve 1 relative to the box, and after the fixing rod 2 is installed in the sleeve 1, the threaded rod 22 of the fixing rod 2 cooperates with the positioning block 8, and the limiting groove 11 on the light rod 21 cooperates with the second dial 10 on the inner wall of the sleeve 1 to complete the limiting.
