Convenient-to-fix positioning and mounting sleeve for electrical engineering

Abstract

The invention discloses a convenient-to-fix positioning and mounting sleeve for electrical engineering. The sleeve comprises an inner pipe, an outer sleeve sleeved outside the inner pipe and a device box fixed at the bottom of the outer sleeve, and an annular cavity is arranged in the outer sleeve. By arranging a soot blowing mechanism, dust on the surface of a cable can be treated when a clamping plate is opened so that the dust can be collected in a second cavity, when more and more dust is in the second cavity, a sliding plate can be extruded to move, and then a displacement rod can move left and right; meanwhile, the tail end of the arranged displacement rod is a conical surface, when the displacement rod moves, the fixing needles continuously move towards the outer side of the positioning rod, the fixing needles can be effectively inserted into the concrete due to the fact that the fixing needles are thin and long, and the fixing needles are stably inserted into the concrete due to the facts that the number of the fixing needles is large and the fixing needles surround the outer portion of the positioning rod by a circle; and therefore, the sleeve main body is still very stable after being used for a long time.

Description

technical field [0001] The invention relates to the technical field related to electrical engineering, in particular to a positioning installation sleeve for electrical engineering that is convenient for fixing. Background technique [0002] Electrical engineering is an indispensable part of the modern building construction process, in which the basic operation is to install and connect cables and other objects in the building wall. In actual operation, it needs to be used to reserve in the wall The installation sleeve is used to facilitate the passage of cables when the wall is formed in the later stage, but the existing installation sleeve still has the following disadvantages in actual use: 1. Since the installation sleeve is connected to the wall, the installation sleeve When adding cables inside or processing the original cables, the dust on the wall will often enter the interior of the installation sleeve, making the surface of the cable contaminated with dust.

[0002] Electrical engineering is an indispensable part of the modern building construction process, in which the basic operation is to install and connect cables and other objects in the building wall. In actual operation, it needs to be used to reserve in the wall The installation sleeve is used to facilitate the passage of cables when the wall is formed in the later stage, but the existing installation sleeve still has the following disadvantages in actual use: 1. Since the installation sleeve is connected to the wall, the installation sleeve When adding cables inside or processing the original cables, the dust on the wall will often enter the interior of the installation sleeve, making the surface of the cable contaminated with dust. When used for a long time, the dust can combine with the moisture in the air and form on the surface of the cable. Agglomeration will affect the later use or maintenance of the cable, and even corrode the surface of the cable in severe cases; 2. The installation sleeve will loosen with the wall after long-term use. Affect the normal use of the casing, the existing technology is to fill the gap between the casing and the wall with a filler, but the depth between the casing and the wall cannot be completely filled with the filler, so the symptoms are not cured; 3 , The existing casing usually needs to clamp the cable, which requires the use of airbag clamping parts, but the airbag will leak after a long time of use, affecting the clamping of the cable, and the use effect is poor
