Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrical construction and related accessories, and more specifically, to a pre-buried positioning sleeve for electrical installation construction. Background Art
[0002] During the construction process, it is generally necessary to pre-embed positioning sleeves in the building body, and use the pre-embedded positioning sleeves to pass through and install wires and cables after the construction is completed. However, the positioning sleeves are not convenient to be positioned and tied with the steel cage during the pre-embedding process, which reduces the pre-embedding efficiency. In addition, the pre-embedded positioning sleeves are easy to clog the holes when pouring concrete, which is not convenient for connecting the two ends of the pipeline in the later stage.
[0003] For example, announcement number CN221009724U discloses a pre-buried positioning sleeve for electrical installation construction, which includes a first positioning sleeve body and a second positioning sleeve body installed directly above it. Adjustment disks are provided on the outer sides of the outer walls of the first positioning sleeve body and the second positioning sleeve body.
[0004] It can be seen from the above-mentioned public scheme that the positioning sleeve adjusts the embedded depth through the adjusting disk and is positioned on the building steel cage. Its structure is cumbersome and complicated. After being inserted into the steel cage, it also takes a long time to position with the steel cage, which reduces the embedded efficiency. In addition, the holes set on the surface of the fixed disk at both ends of the positioning sleeve are easy to cause concrete to enter and block the holes after solidification during concrete pouring, which brings great inconvenience to the subsequent connection of the pipeline.

The number of the fixing block 19 and the threaded hole 20 is the same, which is convenient for fixing the position of the connecting screw during the later pipeline connection. A lower groove 18 is provided on the other surface of the lower fixing plate 17. The inner diameters of the upper groove 15 and the lower groove 18 are the same. The outer diameter of the limit block 22 is larger than the inner diameter of the upper groove 15, which is convenient for the limit block 22 to be positioned by compression elastic force. A threaded hole 20 is provided at the bottom of the lower groove 18, and a sealing plug 21 is inserted into the inner wall of the threaded hole 20 and the through hole 16.
[0026] The inner wall of the limiting groove 27 is in contact with the surface of the guide bar 11. When the limiting groove 27 intersects with the notch 12, the limiting plate 23 can be selected.
