Description

Technical Field

[0001] The utility model relates to the technical field of decoration construction auxiliary devices, in particular to a central line box positioning device for a prefabricated component. Background Art

[0002] During the house decoration process, it is necessary to pre-embed the wire box in the wall to match the wires and pipelines. When pre-embedding the wire box, the main steps include filling, positioning and fixing the wire box. Among them, the positioning step is used to ensure that the wire box is flush with the structural surface, the spacing between the wire boxes in a row is uniform, and the elevation of the wire boxes in a row is consistent, so as to ensure the aesthetics of the wire box after installation. Prefabricated components are partially used to facilitate the positioning of the wire box. However, during the shaping and fixing operations such as casting, the wire box will still be affected by external impacts, which will cause the wire box to bulge, rotate, and shift, making the fixing effect of the two unstable, and the subsequent use of the wire box is less safe and convenient. Utility Model Content

A guiding mechanism is provided between the base plate and the rotating motor for circumferential and radial positioning and axial guiding of the two. The bottom of the first positioning rod is rotatably connected to a first suction cup that is adsorbed on the bottom of the inner wall of the wire box. The wire box is inserted into the wire box hole on the prefabricated component.

[0008] As a further description of the above technical solution:

[0009] The bottom end of the second positioning rod is hinged on the second connecting member, and the second connecting member is fixed on the upper end of the second suction cup.

[0010] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0014] As a further description of the above technical solution:

[0015] The bottom of the first positioning rod is rotatably connected to the rotating block, and the first suction cup is fixed on the bottom of the rotating block.

[0016] As a further description of the above technical solution:

[0017] A positioning ring is arranged along the circumference of the outer side wall of the wire box, and the positioning ring abuts against the outer surface of the prefabricated component to control the depth.

[0018] In summary, due to the adoption of the above technical solution, the utility model has the following advantages compared with the prior art:

[0019] Beneficial effects:

[0020] The device positions the substrate, the second positioning rod and the prefabricated component by adsorbing the second suction cup of the second positioning rod on the outer surface of the prefabricated component, and rotating the first positioning rod to rotate and screw it with the substrate through the external thread. The sleeve and the guide rod have circumferential radial limiting and axial guiding effects, so that the first positioning rod continuously approaches the bottom of the inner wall of the wire box, and when the first suction cup is adsorbed on the bottom of the inner wall of the wire box, it continues to be screwed in, reducing the distance between the rotating motor and the substrate, thereby appropriately increasing the depth of the first positioning rod, playing a pre-tightening positioning role, that is, completing the positioning between the first positioning rod, the substrate and the wire box, and then realizing the positioning of the prefabricated component and the wire box, and then the two can be cast and fixed operations such as casting can be carried out. The positioning operation is convenient, the positioning of the two is stable, and the problem of unstable fixing effect caused by displacement of the wire box during casting and other shaping and fixing operations can be effectively avoided.
