Description

Technical Field

[0001] This utility model relates to the field of electrical materials, and in particular to a conduit threading device. Background Technology

[0002] Threading electrical wires through conduits or cable trays is a common and challenging task. Traditional methods often rely on simple wire pullers, but their drawbacks are obvious. First, insufficiently rigid wires are prone to bending and jamming when encountering bends or obstacles in the conduit, while overly rigid wires are difficult to maneuver. Specifically, indoor conduits often involve bends, and traditional wire pullers frequently fail to thread the wires smoothly, making the process extremely time-consuming and labor-intensive, heavily reliant on the operator's experience and dexterity.

[0003] There are some existing technologies that include wire-threading robots that can walk inside pipes and pull wires through them. However, such equipment is not suitable for small-diameter conduits used for optical cables and electrical cables in ordinary building projects. Furthermore, some wires require bottom-up threading, such as the cable from a wall switch to a ceiling light source. Such equipment is completely unsuitable for these tasks, and it is even more difficult to use a wire threader for threading.

[0004] There is currently no corresponding solution to the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a conduit threading device that is simple in structure, low in cost, suitable for indoor small-diameter conduit threading, and especially suitable for threading conduits with many bends within a certain length range.

[0006] The equipment includes a walking hood and an airlock device; The aforementioned walking hood is a cap structure with a lead wire suspension body inside; The airlock device includes a frustum-shaped sealing body, which is hollow inside, open at the front end, and has a baffle at the rear with a lead wire slot. An air passage is provided on the side of the sealing body, and the air passage is connected to the internal cavity of the sealing body. A lead wire is attached to the lead wire suspension body, and the lead wire passes through the lead wire slot.

[0007] The effect achieved is that the walking hood is first inserted into the conduit opening and pushed forward a certain distance, the sealing body is inserted into the opening, and a high-pressure air source is connected in the air passage on its side wall. The high-pressure air source blows air into the interior, causing the walking hood to move inside the pipe and eventually exit through the conduit, completing the wiring of the lead wire; then the end of the lead wire is connected to an electric wire or optical cable, and the overall wiring operation is completed based on the lead wire.

[0008] The beneficial effects of this utility model are: This utility model fills a gap in the market with its simple structure. It is based on compressed air to drive or move the wind cap inside the conduit, thereby completing the transmission of the lead wire. In this case, the lead wire can be quickly passed through the conduit. It is especially suitable for small-diameter conduit wiring in home decoration environment. Its structure is simple and its cost of manufacture and use is low. Attached Figure Description

Detailed Implementation

[0010] Reference Figure 1 , Figure 2 The present invention provides a conduit threading device, which includes a walking hood 1 and an airlock device 2. The walking hood 1 is a cap structure, and a lead wire suspension body 14 is provided inside it; The air-locking device 2 includes a frustum-shaped sealing body 21. The sealing body 21 is hollow inside, with a transparent front end, and a baffle 221 is provided at its rear. A lead wire slot is provided on the baffle 221. An air passage is provided on the side of the sealing body 21, and the air passage is connected to the internal cavity of the sealing body 21. A lead wire 3 is attached to the lead wire suspension body 14, and the lead wire 3 passes through the lead wire slot.

[0011] The effect achieved is that the walking hood 1 is first inserted into the conduit opening and pushed forward a certain distance, the sealing body 21 is inserted into the opening, and a high-pressure air source is connected in the air passage on its side wall. The high-pressure air source blows air into the interior, causing the walking hood 1 to move inside the pipe and eventually pass through the conduit to complete the wiring of the lead wire 3; then the tail end of the lead wire 3 is connected to an electric wire or optical cable, and the overall wiring operation is completed based on the lead wire 3.

[0012] Example 1, refer to the accompanying drawings in the specification. Figure 1 The walking hood 1 is integrally set, including the hood body and the windproof plate; the hood body includes a conical hood 11 and an air collection tube 12 extending sequentially from the edge of the hood 11 from top to bottom; the bottom of the air collection tube 12 is integrally set with a windproof ring 13 extending from the edge. The windproof ring 13 is available in various outer diameter specifications corresponding to the inner diameter of the conduit.

[0013] Furthermore, the outer diameter of the windshield ring 13 includes at least two specifications: 16mm and 20mm.

[0014] This allows the equipment to fit snugly against the pipe wall, and when compressed air enters, it pushes the air cap to move inside the pipe.

[0015] Example 2, refer to the accompanying drawings in the specification. Figure 2 The walking hood 1 is a hollow, flat cone shape.

[0016] The effect achieved is that, compared to embodiment 1, this configuration makes it easier to achieve a lightweight walking hood 1, which is easily driven by compressed air to quickly pass through the conduit.

[0017] In Example 3, the walking hood 1 is made of thin-walled plastic.

[0018] Furthermore, the lead wire 3 is suspended in the form of a hanging ring integrated into the walking hood 1.

[0019] The effect achieved is that the overall equipment is lightweight, and its internal cavity can withstand compressed air, i.e., circulate the air, and quickly pass through the conduit with the compressed air.

[0020] In Example 4, the lead wire 3 is a high-strength, lightweight lead wire 3.

[0021] Preferably, the lead wire 3 is a synthetic fiber wire with a smooth exterior and a diameter of no more than 2 mm.

[0022] The effect achieved is to ensure that the overall equipment is lightweight and the rope is flexible, that is, not hindered by the strength of the lead wire 3 itself.

[0023] Example 5, refer to the accompanying drawings in the specification. Figure 3 The sealing body 21 is integrally provided with a base 22 at its lower part. An air gun connection pipe 4 is provided on the side of the base 22. The air gun connection pipe 4 is a bent pipe and is bent towards the bottom of the base 22. The air gun connector 4 is connected to the air chamber inside the sealing body 21 via an air passage.

[0024] Furthermore, the baffle 221 is a conical baffle 221, with a lead wire slot at its end. That is, the top of the conical baffle 221 has an opening for the lead wire 3 to pass through.

[0025] Furthermore, the sealing body 21 is provided with airtight rings arranged in an array from top to bottom.

[0026] Preferably, the air-locking device 2 is made entirely of elastic rubber, and the inner diameter of the lead wire groove is slightly larger than the outer diameter of the lead wire 3.

[0027] This achieves the effect of preventing air leakage from the tail of the airlock device 2.

[0028] Preferably, the air gun connection pipe 4 is configured to correspond to the handheld air gun, that is, based on the readily available air compressor and handheld air gun at the construction site, the equipment can be quickly connected to a high-pressure air source.
