[0005] To achieve the above objectives, the present invention provides the following technical solution: an open anchor for building construction, comprising an anchor plate, a second anchor and a linkage slide rod, wherein the anchor plate is provided with a first anchor;

[0006] The first anchorage is located inside the second anchorage;

[0007] The linkage slide bar is equipped with an annular connecting post, which is used to limit the first anchor and the second anchor.

[0008] Preferably, the first anchorage has a T-shaped groove inside, and a T-shaped reinforcing bar is fixedly installed inside the T-shaped groove. This arrangement can increase the stability of the first anchorage and the second anchorage.

[0009] Preferably, both the interior of the first anchor and the interior of the second anchor are provided with tapered holes.

[0010] Preferably, the second anchor has a square groove inside, a first fixing block is fixedly installed on the inner wall of the square groove, a return spring is fixedly installed on one side of the first fixing block, an annular connecting plate is fixedly installed on one side of the return spring, a linkage slide rod is fixedly installed on one side of the annular connecting plate, one end of the linkage slide rod extends to one side of the first fixing block and is fixedly installed with a pull rod, the linkage slide rod and the first fixing block are slidably installed, a second fixing block is fixedly installed on the inner wall of the square groove, and an annular connecting column is fixedly installed on the other side of the annular connecting plate.

[0011] Preferably, the second fixing block has a hole inside for the movement of the annular connecting column, and the T-shaped reinforcing bar has a limiting hole inside for the movement of the annular connecting column. One end of the annular connecting column passes through the hole on the second fixing block and extends into the limiting hole inside the T-shaped reinforcing bar.

[0012] Preferably, the anchor plate has a circular hole inside, and a circular groove is formed inside the circular hole. A fixing ring is fixedly installed on the outer wall of the first anchor, and the fixing ring is located in the circular groove on the anchor plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This open anchor for building construction, through the setting of the linkage sliding rod, can drive the annular connecting column to move. After the annular connecting column is moved, the first anchor and the second anchor can be connected. In this way, when the first anchor is used, the first anchor and the second anchor can be combined according to the diameter of the circular hole on the anchor plate. This makes the first anchor applicable to different types of anchor plates, increasing the applicability of the first anchor and the practicality of the device. Moreover, this installation method is relatively simple and easy for workers to operate, which not only reduces the connection time of workers, but also reduces the labor intensity of workers during connection.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution: an open anchor for building construction, including an anchor plate 1, a second anchor 3 and a linkage slide rod 11. The anchor plate 1 is provided with a first anchor 2; the first anchor 2 is located inside the second anchor 3; the linkage slide rod 11 is provided with an annular connecting column 10, which is used to limit the first anchor 2 and the second anchor 3.

[0021] Furthermore, the first anchor 2 has a T-shaped groove inside, and a T-shaped reinforcing rib 4 is fixedly installed inside the T-shaped groove. Both the first anchor 2 and the second anchor 3 have tapered holes 12 inside. The second anchor 3 has a square groove inside, and a first fixing block 6 is fixedly installed on the inner wall of the square groove. A return spring 7 is fixedly installed on one side of the first fixing block 6, and an annular connecting plate 8 is fixedly installed on one side of the return spring 7. A linkage slide rod 11 is fixedly installed on one side of the annular connecting plate 8, with one end of the linkage slide rod 11 extending to one side of the first fixing block 6 and a pull rod fixedly installed thereon. The linkage slide rod 11 and the first fixing block 6 are slidably installed. A second fixing block 9 is fixedly installed on the inner wall of the square groove, and an annular connecting post 10 is fixedly installed on the other side of the annular connecting plate 8. The second fixing block 9 has a hole inside that allows the annular connecting post 10 to move. The T-shaped reinforcing rib 4 also has a hole inside that allows the annular connecting post 10 to move. The limiting hole is provided. One end of the annular connecting column 10 passes through the hole on the second fixing block 9 and extends into the limiting hole inside the T-shaped reinforcing rib 4. The anchor plate 1 has a circular hole inside, and a circular groove is formed inside the circular hole. A fixing ring 5 is fixedly installed on the outer wall of the first anchor 2. The fixing ring 5 is located in the circular groove on the anchor plate 1. This arrangement can drive the annular connecting column 10 to move. After the annular connecting column 10 is moved, the first anchor 2 and the second anchor 3 can be connected. In this way, when the first anchor 2 is used, the first anchor 2 and the second anchor 3 can be combined according to the diameter of the circular hole on the anchor plate 1. This allows the first anchor 2 to be used with different types of anchor plates 1, increasing the applicability of the first anchor 2 and the practicality of the device. Moreover, this installation method is relatively simple and easy for workers to operate. It can not only reduce the connection time of workers, but also reduce the labor intensity of workers during connection.

[0022] Working principle: When in use, the worker pulls the linkage slide rod 11. The movement of the linkage slide rod 11 moves the annular connecting plate 8 and the annular connecting column 10. After the annular connecting column 10 is moved, the first anchor 2 is placed inside the second anchor 3. Then the linkage slide rod 11 is released. After the linkage slide rod 11 is released, it can rebound through the return spring 7. After the return spring 7 rebounds, the annular connecting column 10 can be reset. After the annular connecting column 10 is reset, the first anchor 2 and the second anchor 3 can be connected.
