Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a pre-embedded fastener for easy connection includes:

[0024] Sleeve 1 and insert rod 2. Two connecting rings 101 are fixedly connected to the surface of sleeve 1. The surface of the connecting rings 101 is provided with evenly distributed grooves 102. Two sliding grooves 103 are provided on the inner side of the connecting rings 101. The sliding grooves 103 have an "L" shaped cross section. The inner wall of the sliding grooves 103 is provided with a slot 104. One end of the insert rod 2 is fixedly connected to a connecting plate 201.

[0025] Limiting component 3 is disposed inside the insert rod 2 and is used for the connection and positioning of the insert rod 2 and the sleeve 1;

[0026] The limiting component 3 includes two limiting rods 302 that are slidably connected to the inner wall of the insertion rod 2. One end of the limiting rod 302 passes through the insertion rod 2 and extends into the interior of the slide groove 103. A second spring 309 is fixedly connected to the surface of the limiting rod 302, and the other end of the second spring 309 is fixedly connected to the inner wall of the insertion rod 2.

[0027] During the pouring process, the sleeve 1 is pre-embedded and poured. After the concrete has solidified, the insert rod 2 is inserted into the inside of the sleeve 1 for connection. During this process, the limiting rod 302 is aligned with the slide groove 103 and inserted until it is inserted to the bottom. Then, the insert rod 2 is rotated to drive the limiting rod 302 to slide to the connection between the slot 104 and the slide groove 103.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, a rotating rod 301 is rotatably connected inside the insertion rod 2. A rotating block 303 is fixedly connected to one end of the rotating rod 301. Two sliding grooves 310 are symmetrically distributed on the surface of the rotating block 303. The cross-section of the sliding grooves 310 is "L" shaped. The other end of the limiting rod 302 extends into the interior of the adjacent sliding groove 310.

[0029] The other end of the rotating rod 301 passes through the insert rod 2 and the connecting plate 201 in sequence and is fixedly connected to the knob 306. The surface of the rotating rod 301 is fixedly connected to the turntable 304 located inside the connecting plate 201.

[0030] After the limiting rod 302 is slid to the connection between the slot 104 and the slide groove 103, rotating the knob 306 can drive the rotating rod 301 to rotate, thereby driving the rotating block 303 to rotate synchronously. During this process, the position of the slide groove 310 can be changed, thereby causing the limiting rod 302 to rotate to the corner of the slide groove 310. At this time, under the action of the second spring 309, the limiting rod 302 can be driven to move upward along the inner wall of the slide groove 310. At the same time, the other end of the limiting rod 302 can be inserted into the inside of the slot 104 to complete the limiting of the insertion rod 2.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the surface of the turntable 304 is provided with uniformly distributed limiting grooves 305, and one inner wall of the limiting groove 305 is set with an inclined surface.

[0032] A positioning rod 307 is slidably connected to the inner wall of the connecting plate 201. One end of the positioning rod 307 extends into the interior of the adjacent limiting groove 305, and the other end of the positioning rod 307 is fixedly connected to a first spring 308. The other end of the first spring 308 is fixedly connected to the inner wall of the connecting plate 201.

[0033] A sealing ring 202 is fixedly connected to the surface of the connecting plate 201. The sealing ring 202 is a rubber material component.

[0034] The sealing ring 202 can seal the connection between the insert rod 2 and the sleeve 1, reducing rust caused by rainwater intrusion.

[0035] During the rotation of the rotating rod 301, the turntable 304 rotates synchronously. During the rotation of the turntable 304, the positioning rod 307 can be pushed along the inner wall of the connecting plate 201 by the inclined inner wall of the limiting groove 305 and squeeze the first spring 308. When the next limiting groove 305 moves to the positioning rod 307, the positioning rod 307 can be inserted into the interior of the limiting groove 305 under the action of the first spring 308. During the reverse rotation of the turntable 304, the positioning rod 307 can be blocked by the other inner wall of the limiting groove 305, thereby completing the limiting of the rotating rod 301, so as to achieve the effect of limiting the rotating block 303, and thus achieving the effect of limiting the position of the positioning rod 307. This makes the installation of the insertion rod 2 simple. Compared with the traditional threaded connection, this method is easier to install and connect.

[0036] In use, the sleeve 1 is pre-embedded and poured during the concrete pouring process. After the concrete has solidified, the insert rod 2 is inserted into the sleeve 1 for connection. During this process, the limiting rod 302 is aligned with the sliding groove 103 and inserted until it reaches the bottom. Then, the insert rod 2 is rotated to drive the limiting rod 302 to slide to the connection point between the slot 104 and the sliding groove 103. After the limiting rod 302 is slid to the connection point between the slot 104 and the sliding groove 103, rotating the knob 306 can drive the rotating rod 301 to rotate, thereby driving the rotating block 303 to rotate synchronously. During this process, the position of the sliding groove 310 can be changed, thereby causing the limiting rod 302 to rotate to the corner of the sliding groove 310. At this time, the second spring can be launched. Under the action of the spring 309, the limiting rod 302 moves upward along the inner wall of the sliding groove 310. At the same time, the other end of the limiting rod 302 can be inserted into the inside of the slot 104 to limit the insertion rod 2. Under the combined action of the limiting groove 305, the positioning rod 307 and the first spring 308, the positioning rod 307 can be blocked by the other inner wall of the limiting groove 305 during the reverse rotation of the turntable 304, thereby limiting the rotating rod 301 and achieving the effect of limiting the rotating block 303. This achieves the effect of limiting the position of the positioning rod 307, making the installation of the insertion rod 2 simple. Compared with the traditional threaded connection, this method is simpler to install and easier to connect.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
