Detailed Implementation Example 1

[0021] like Figures 1-3 As shown in the figure, the adjustable pre-embedded pipe sleeve proposed in this embodiment includes a pipe sleeve body, a length adjustment component, and multiple sets of fixing components.

[0022] The main body of the tube sleeve includes an outer tube 1 and an inner tube 2, with the end of the inner tube 2 movably located inside the outer tube 1. A sealing ring 41 is installed on the outer tube 1 at the end furthest from its outer side, and the sealing ring 41 is in clearance fit with the outer wall of the inner tube 2. The sealing ring 41 is used to improve the sealing performance between the outer tube 1 and the inner tube 2. A connecting ring 3 is connected to the outer end of both the outer tube 1 and the outer end of the inner tube 2. A sealing gasket 42 is installed on the outer surface of both connecting rings 3, and the sealing gasket 42 is used to improve the sealing performance between the connecting ring 3 and the wooden board mold. A length adjustment component is used to adjust the distance between the outer end of the outer tube 1 and the outer end of the inner tube 2.

[0023] Multiple sets of fixing components are installed on the outer tube 1 and the inner tube 2 in equal quantities. The fixing components include a first rotating seat 8, bolts 9, threaded rings 10, connecting rods 11, outer sleeves 12, round tubes 13, and steel nails 14. The first rotating seat 8 is connected to the main body of the tube sleeve. The bottom end of the bolts 9 is rotatably connected to the first rotating seat 8. Multiple bolts 9 are arranged in parallel. The threaded rings 10 are threadedly connected to the bolts 9. The round tubes 13 are connected to the corresponding side connecting rings 3. The outer sleeves 12 are slidably installed on the outside of the round tubes 13. The two ends of the connecting rods 11 are rotatably connected to the threaded rings 10 and the outer sleeves 12, respectively. The steel nails 14 are connected to the inner wall of the outer sleeves 12. The connecting rings 3 have multiple through holes 301 for the steel nails 14 to pass through.

[0024] Two connecting rods 15 are symmetrically connected to both the outer pipe 1 and the inner pipe 2. The connecting rods 15 have round holes 151. The construction workers pass the wire through the round holes 151 and tie it to the steel bar, thereby achieving the fixation of the main body of the pipe sleeve.

[0025] In this embodiment, when installing the pre-embedded pipe sleeve, it is fixed to the inside of the reinforcing cage using wire or other fasteners. The length of the pipe sleeve body is adjusted according to the wall thickness. During installation, multiple bolts 9 are ensured to be vertically facing upwards. Hex socket head cap screws can be used for bolts 9, ensuring the bolt heads are at the top. The construction worker drives the bolts 9 to rotate using an electric torque screwdriver. The rotation of the bolts 9 drives the threaded ring 10 to move downwards, pushing the outer sleeve 12 to move with the cooperation of the connecting rod 11. The movement of the outer sleeve 12 drives the steel nail 14 to move until the steel nail 14 is inserted into the wooden mold. Subsequently, the above method is used to adjust multiple sets of fixing components to achieve the fixing of the pre-embedded pipe sleeve. In summary, this technical solution converts the rotation of the vertical bolts 9 into the lateral movement of the steel nail 14 by setting fixing components, thus facilitating the insertion of electric tools into the reinforcing cage to drive the bolts 9 without the need to place the electric tools horizontally or at an angle, thereby improving installation efficiency and reducing installation difficulty. The pipe sleeve body has the advantage of being telescopic and adjustable, making it highly adaptable. Example 2

[0026] like Figure 2As shown in this embodiment, an adjustable pre-embedded pipe sleeve is proposed. Compared with the first embodiment, in this embodiment, the length adjustment component includes a threaded sleeve 5, a threaded rod 6, and a knob 7. A second rotating seat 16 is connected to the outer wall of the inner pipe 2. The threaded sleeve 5 is rotatably mounted on the second rotating seat 16. The knob 7 is connected to the end of the threaded sleeve 5. The threaded rod 6 is threadedly connected to the threaded sleeve 5, and the threaded rod 6 is connected to the connecting ring 3 adjacent to the side of the outer pipe 1. The construction personnel can manually drive the knob 7 to rotate, which can drive the threaded sleeve 5 to rotate. By adjusting the rotation direction of the threaded sleeve 5, the extension and retraction length of the pipe sleeve body can be adjusted. Moreover, since the threaded connection has self-locking properties, the length of the pipe sleeve body can be locked.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
