Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a protective device for conduits during the pre-embedded construction of building electrical equipment installation. Background Technology

[0002] In building construction, conduits need to be pre-installed to facilitate the future laying of electrical wiring. However, the electrical wiring is only laid later, through the pre-reserved openings in the conduits. To prevent cement or gravel from falling into the conduits during construction, plastic caps are typically used to seal and protect the conduit openings. In existing technology, the cap consists of a positioning post connected to a ring-shaped cover at the top. It relies on the friction between the cap, the positioning post, and the conduit wall to fit over the conduit opening. However, in actual manufacturing, due to limitations in processing precision, a gap may exist between the cap and the conduit. Therefore, to prevent it from detaching from the cap during pouring, tape is usually wrapped around the outside for reinforcement, which is rather cumbersome. Utility Model Content

[0003] The purpose of this utility model is to provide a protective device for conduits during the pre-embedded construction of building electrical equipment installation, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective device for conduits during the pre-embedded construction of building electrical equipment installation, comprising a positioning column, a cap at the upper end of the positioning column, a pull-out member at the upper end of the cap, a limiting soft plug inside the positioning column, an air collection chamber inside the cap, a plurality of air inlets on the air collection chamber, a limiting component one above the upper limiting soft plug of the positioning column, and a limiting component two inside the cap.

[0005] Preferably, the pull-out member includes a connecting post and a connecting plate, the connecting post being mounted on the cap and the connecting plate being disposed on the connecting post.

[0006] Preferably, the positioning post is provided with a groove, and the limiting component is disposed in the groove. The limiting component includes a compression airbag and a plurality of air guide pipes. The compression airbag is disposed in the groove, and the plurality of air guide pipes are disposed on the compression airbag. The air guide pipes are connected to the air collection chamber.

[0007] Preferably, the cap is provided with a second groove, and the second limiting component is disposed in the second groove. The second limiting component includes a second compression airbag and a plurality of second air guide pipes. The second compression airbag is disposed in the second groove, and the plurality of second air guide pipes are disposed on the second compression airbag. The second air guide pipes are connected to the air collection chamber.

[0008] Preferably, the cap is provided with a limit strip.

[0009] Preferably, the positioning post is provided with a receiving groove, and the limiting soft plug is disposed in the receiving groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model uses the combination of a limiting soft plug, an air collection chamber, an air inlet, a limiting component one, and a limiting component two to align the positioning pin with the tube opening and insert it, so that the tube is located between the positioning pin and the cap. The gas between the positioning pin and the cap is squeezed by the side wall of the tube, compressing its internal air pressure, causing the compression airbag one and the compression airbag two to inflate and expand, so that the compression airbag one and the compression airbag two are tightly attached to the side wall of the tube, making it difficult for them to fall off.

[0012] 2. This utility model also facilitates insertion and removal by operators through the cooperation of the pull-out part and the cap, and can be reused repeatedly. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: a protective device for conduits during the pre-embedded construction of building electrical equipment installation, including a positioning post 1 inserted inside the conduit, a cap 2 fitted onto the outer wall of the conduit at the upper end of the positioning post 1, a pull-out member 3 at the upper end of the cap 2, a limiting soft plug 4 installed inside the positioning post 1, an air collection chamber 5 opened on the inner side of the cap 2, a plurality of air inlets 6 opened on the air collection chamber 5, a limiting component 1 7 installed on the upper side of the limiting soft plug 4 of the positioning post 1, and a limiting component 2 8 installed on the inner side of the cap 2;

[0019] The drawing component 3 includes a connecting post 31 and a connecting plate 32. The connecting post 31 is mounted on the cap 2, and the connecting plate 32 is mounted on the connecting post 31. The cap 2 and the drawing component 3 are integrally formed to increase their strength. A groove is provided on the positioning post 1, and a limiting component 7 is installed in the groove. The limiting component 7 includes a compression airbag 71 and several air guide pipes 72. The compression airbag 71 is installed in the groove, and the several air guide pipes 72 are installed on the compression airbag 71. Air pipe 72 is connected to air collection chamber 5; a groove 2 is provided on cap 2, and limiting component 2 8 is installed in groove 2. Limiting component 2 8 includes compression airbag 2 81 and several air guide pipes 2 82. Compression airbag 2 81 is installed in groove 2, and several air guide pipes 2 82 are installed on compression airbag 2 81. Air guide pipes 2 82 are connected to air collection chamber 5; limiting strip 9 is installed on cap 2; a receiving groove 10 is provided on positioning post 1, and limiting soft plug 4 is installed in receiving groove 10.

[0020] Working principle: When using this utility model, the positioning post 1 is aligned with the conduit opening and inserted, so that the conduit is located between the positioning post 1 and the cap 2. The gas between the positioning post 1 and the cap 2 is compressed by the side wall of the conduit, compressing its internal air pressure. This causes the compression airbags 81 and 71 to inflate and expand, making them tightly adhere to the side wall of the conduit, preventing them from falling off. When removing the conduit, the limiting soft plug 4 increases the friction between the positioning post 1 and the side wall of the conduit, further preventing slippage. During disassembly, it is convenient for operators to pull out the connecting plate 32 for insertion and removal. It can be reused repeatedly and has the advantages of being easy to use and having good performance.
