[0014] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the description of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] In the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0016] The directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, “top”, “bottom”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0017] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0018] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0019] See also Figure 1 The anchor provided by the present invention comprises an expansion sleeve 1, an anchor rod 4 and a safety component. The safety component is connected to the expansion sleeve 1. In the initial state, the safety component is hidden in the expansion sleeve 1. In the fixed state, the anchor rod 4 is inserted into the expansion sleeve 1 so that the safety component is detached from the expansion sleeve 1 and enters the cavity of the hollow brick 5.

[0020] It is understandable that during construction, the hollow brick wall is first punched, please refer to Figure 2 In the initial state, when the expansion sleeve 1 is inserted into the fixing hole in the hollow brick wall, the insurance component is hidden in the expansion sleeve 1. The hiding can be partial hiding or full hiding. After the hiding is completed, the expansion sleeve 1 is inserted into the fixing hole. The inner diameter of the fixing hole is slightly larger than the inner diameter of the fixing hole. Therefore, when the insurance component is partially hidden, it will not interfere with the insertion of the expansion sleeve 1. After the expansion sleeve 1 is inserted, it begins to enter the fixed state. Please refer to Figure 3 When the anchor rod 4 is inserted into the expansion sleeve 1, the anchor rod 4 will squeeze the safety component out of the expansion sleeve 1. After extrusion, the safety component still remains connected to the expansion sleeve 1 and enters the cavity of the hollow brick 5. In this case, if the thermal insulation layer 6 is separated from the hollow brick wall, the expansion sleeve 1 will be separated from the fixing hole, and the safety component will interfere with the hollow brick 4, thereby pulling the column expansion sleeve 1, thereby effectively preventing the thermal insulation layer 6 from falling off.

[0021] See also Figure 1 In some embodiments, the safety component includes an elastic member 2 and a limiting rod 3. The expansion sleeve 1 is connected to the limiting rod 3 through the elastic member 2. Correspondingly, an insertion hole is provided on the expansion sleeve 1. In the initial state, under the action of external force, the elastic member 2 is deformed so that the limiting rod 3 is inserted into the expansion sleeve 1 through the insertion hole.

[0022] It can be understood that the insertion hole on the expansion sleeve 1 is an inclined hole, which greatly facilitates the insertion of the limit rod 3. The limit rod 3 can be a metal rod, and the elastic member 2 can be a spring. In the initial state, the spring is bent so that the limit rod 3 is inserted into the insertion hole. When the anchor rod 4 is inserted into the expansion sleeve 1, the limit rod 3 is separated from the expansion sleeve 1. Under the action of the elastic force of the spring, the limit rod 3 is in the cavity of the hollow brick 5, thereby greatly improving the use effect of the safety component.

[0023] Please continue reading Figure 1In some embodiments, the expansion sleeve 1 includes a cylinder and a limiting plate 101, the insertion hole is opened on the cylinder, and the limiting plate 101 is connected to the cylinder.

[0024] It can be understood that the limiting piece 101 is located at the end of the cylinder. When the expansion sleeve 1 is inserted into the fixing hole, the limiting piece 101 fits the thermal insulation layer 6, thereby improving the fixing effect of the thermal insulation layer 6.

[0025] See also Figure 1 In some embodiments, the cylinder includes a main body and a barb 103, one end of the barb 103 is connected to the main body, and the other end of the barb 103 extends obliquely toward the direction of the limiting piece 101 on the main body.

[0026] It is understandable that the barbs 103 may be evenly distributed on the main body, and the barbs 103 may well improve the connection effect between the cylinder and the hollow wall.

[0027] See also Figure 1 In some embodiments, the main body includes a main body section 102 and a reducing section 104 , the reducing section 104 is connected to the main body section to form a cone shape, the insertion hole is opened in the main body section 102 , and the barb 103 is set on the main body section 102 .

[0028] It can be understood that the main body of the structure can be easily inserted into the fixing hole.

[0029] From the above description, it can be known that the anchor bolt and the safety component provided by the present invention can be stuck inside the hollow brick 5 of the hollow brick wall, thereby pulling the insulation anchor bolt and preventing the insulation layer 6 from falling off immediately, thereby improving safety and avoiding personal and property losses.

[0030] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
