DETAILED DESCRIPTION

[0021] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0022] As Figures 1 to 6 shown, the utility model provides:

[0023] A pre-buried sleeve convenient to install in wall, including steel sleeve 1, both ends of steel sleeve 1 are provided with the extension assembly of resisting template, the outside of steel sleeve 1 is provided with the holding assembly for holding, the top of steel sleeve 1 is provided with the support assembly for supporting steel sleeve 1.

[0024] The extension assembly can drive the fixed disc 5 and rubber pad 6 at both ends of steel sleeve 1 to extrude the template, so that it is close to the reinforced structure, the wall sleeve between the steel template is conveniently increased, the holding assembly is used to make the steel sleeve 1 not rotate when the staff rotates the adjusting nut 10, in addition, the support assembly provides additional support for steel sleeve 1, ensures that it remains stable during the working process.

[0025] As Figure 3 shown, the extension assembly includes the adjusting nut 10 that is screw-connected on the outside of both sides of steel sleeve 1, the opposite side of two adjusting nuts 10 is provided with extrusion ring 3.

[0026] The wrench is rotated to adjust the nut 10, the extrusion ring 3 is rotated along with the rotation of the adjusting nut 10, and slides along the outside of the steel sleeve 1, and then drives the movable rod 13 to move.

[0027] As Figure 4 and Figure 5 shown, the extension assembly further includes the connecting disc 4 provided at both ends of steel sleeve 1, the inside of connecting disc 4 movably is provided with a plurality of movable rods 13, one end of movable rod 13 rotatably is provided with ball 15, the outside of movable rod 13 is provided with the limiting disc 14 for preventing movable rod 13 from falling off, the sidewall of extrusion ring 3 is provided with annular groove 16 for the movement of ball 15.

[0028] Turning the adjusting nut 10 with a wrench causes the compression ring 3 to rotate as well, sliding along the outside of the steel sleeve 1, which in turn moves the movable rod 13, thus reducing friction and resistance. This not only improves the efficiency of the ball bearing 15 but also ensures that the ball bearing 15 maintains good stability during movement. Furthermore, it allows the movable rod 13 to move more smoothly and steadily.

[0029] like Figure 5 As shown, a fixed plate 5 is provided at one end of the movable rod 13; a rubber pad 6 that abuts against the template is provided on the side wall of the fixed plate 5.

[0030] The steel formwork can be compressed using the fixed plate 5 and the rubber pad 6. Specifically, the rubber pad 6 is placed on the side wall of the steel formwork and in close contact with it. This allows the rubber pad 6 to apply pressure to the steel formwork, thereby achieving the compression effect. Furthermore, the presence of the rubber pad 6 significantly increases the friction between it and the steel formwork.

[0031] like Figure 6 As shown, the grip assembly includes connecting rings 11 symmetrically arranged outside the steel sleeve 1; the top of the two connecting rings 11 is provided with grips 2 for holding.

[0032] The handle 2 makes the steel sleeve 1 more stable during operation.

[0033] like Figure 6 As shown, the support assembly includes a top cylinder 12 sleeved on the outside of the steel sleeve 1; a screw 8 is threadedly connected inside the top cylinder 12; the top of the screw 8 passes through the steel sleeve 1 and is provided with a handle; a support plate 9 is rotatably provided at the bottom of the screw 8; telescopic rods 7 are respectively provided on both sides of the bottom of the steel sleeve 1; the telescopic ends of the telescopic rods 7 are connected to the top of the support plate 9.

[0034] The screw 8 drives the top cylinder 12 to move, which in turn drives the steel sleeve 1 to move up and down, and further drives the extension components at both ends of the steel sleeve 1 to move up and down until the extension components are moved to the center point of the steel template, so that the steel template can be subjected to uniform force when it is squeezed.

[0035] Working principle: when the steel formwork is installed, the steel sleeve 1 is placed between the two steel formworks, first rotate the screw rod 8 to drive the top cylinder 12 to move, thereby driving the steel sleeve 1 to move up and down, further driving the extension assembly at both ends of the steel sleeve 1 to move up and down, until the extension assembly is moved to the center point of the steel formwork, so that the steel formwork can be stressed uniformly when being extruded, then the worker holds the handle 2, and rotates the adjusting nut 10 by using a wrench, and the adjusting nut 10 is also driven to rotate while rotating, and the extrusion ring 3 is also driven to rotate while rotating, and the extrusion ring 3 also slides along the outside of the steel sleeve 1, thereby extruding the movable rod 13, driving the movable rod 13 to move towards the outside of the steel sleeve 1, and the movable rod 13 drives the fixed disc 5 and the rubber pad 6 to move while moving, until the rubber pad 6 abuts against the side wall of the steel formwork, thereby extruding the steel formwork, at this time, the wall sleeve can be added between the steel formwork, and after installation, the adjusting nut 10 is reversely rotated, driving the extrusion ring 3 to move reversely, and the extrusion ring 3 also moves away from the movable rod 13, at this time, the steel sleeve 1 can be taken out.

[0036] The above embodiment only expresses one kind of the pre-buried sleeve convenient to install in the wall or several kinds of implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the utility model. It should be pointed out that, for ordinary skilled persons in the art, under the premise of not departing from the concept of the utility model, several modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the appended claims.
