Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a device for unblocking and threading wires through pre-embedded conduits in concealed engineering projects. Background Technology

[0002] Concealed works refer to the physical objects in buildings and structures that are buried inside objects and are not visible from the outside during construction. Most of them are used inside walls to run conduits for the subsequent installation of electrical wires. The wires are inserted into the conduits that are pre-embedded in the wall, and the conduits can protect the wires.

[0003] Currently, when installing electrical wires, a flexible wire guide rod is typically used to pass through one end of the conduit to the other. The required wire is then tied to the end of the guide rod, and the guide rod is pulled out. The guide rod moves the wire inside the conduit, thus threading the wire through the conduit. However, when there are obstacles inside the conduit, some existing wire guide rods have difficulty passing through, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] To address the problem that existing wire-threading rods are difficult to pass through when there are obstacles inside the conduit, resulting in time-consuming, labor-intensive, and inefficient processes, the purpose of this utility model is to provide a device for clearing and threading wires through pre-embedded conduits in concealed engineering projects.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a device for clearing and threading wires through pre-embedded conduits in concealed engineering projects, including a threading rod, which is hollow and has an air passage inside. A threading head is installed at one end of the threading rod, and a crown gear is rotatably installed at one end of the threading head. A conical head is fixedly installed on the outside of the crown gear, and multiple scrapers distributed in a ring are fixedly installed on the outer surface of the conical head. A driving assembly is installed inside the threading head, and the driving assembly includes a fan blade, which is rotatably installed inside the threading head. A driving gear is fixedly installed at the top of the fan blade's shaft, and the driving gear meshes with the crown gear. An air inlet is provided on the threading head.

[0006] Preferably, a drive cavity is provided inside the wire threading head, the fan blade is rotatably installed in the drive cavity, the air inlet is connected to the drive cavity, and the air inlet is located on one side of the drive cavity.

[0007] Preferably, threaded connectors are fixedly installed at both ends of the wire threading rod, a threaded sleeve is fixedly installed at one end of the wire threading head, and the threaded connector on the wire threading rod can be threaded into the threaded sleeve. An air vent is opened in the conical head and the air vent communicates with the drive cavity. A retaining ring is fixedly installed at one end of the wire threading head.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. In this utility model, an air pump can be used to deliver compressed gas into the threading rod, and the compressed gas is transmitted through the air passage inside the threading rod. The compressed gas blows the fan blades to rotate through the air inlet. The fan blades drive the drive gear to rotate, the drive gear drives the crown gear to rotate, the crown gear drives the conical head to rotate, and the conical head drives the scraper to rotate. When there is an obstacle in the conduit, the conical head drives the scraper to rotate, and in conjunction with the manual operation of the threading rod, the obstacle can be cleared and the threading rod can pass through.

[0010] 2. In this utility model, gas can be discharged to the front of the threading head through the air outlet on the conical head, which can blow away the blockage in the wire tube and facilitate the passage of the threading rod. Attached Figure Description

[0018] 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.

[0019] Example: Figure 1-5 As shown, this utility model provides a device for unblocking and threading wires in concealed wall-embedded conduits, including a threading rod 1, which is hollow and has an air passage 101 inside. A threading head 3 is installed at one end of the threading rod 1, and a crown gear 5 is rotatably mounted at one end of the threading head 3. A conical head 6 is fixedly mounted on the outer side of the crown gear 5, and multiple annularly distributed scrapers 7 are fixedly mounted on the outer surface of the conical head 6. A drive assembly 10 is installed inside the threading head 3, including a fan blade 1001, which is rotatably mounted inside the threading head 3. A drive gear 1002 is fixedly mounted at the top of the shaft of the fan blade 1001, and the drive gear 1002 meshes with the crown gear 5. An air inlet 301 is provided on the threading head 3. The threading rod 1 is made of high-carbon steel and can be flexibly bent. In use, the threading head 3 is installed at one end of the threading rod 1, and the other end of the threading rod 1 is connected to the air pump. The threading head 3 and the threading rod 1 are manually inserted continuously from one end of the conduit. At the same time, the air pump delivers compressed gas into the threading rod 1, which is then transmitted through the air passage 101 inside the threading rod 1. The compressed gas enters the threading head 3 through the air inlet 301. The compressed gas blows the fan blade 1001 to rotate, which in turn drives the drive gear 1002 to rotate. The drive gear 1002 drives the crown gear 5 to rotate, which in turn drives the conical head 6 to rotate. The conical head 6 drives the scraper 7 to rotate. When an obstacle appears in the conduit, the conical head 6 drives the scraper 7 to rotate, which, in conjunction with the manual insertion and withdrawal of the threading rod 1 into the conduit, can clear the obstacle and unclog the pipe, facilitating the passage of the threading rod 1.

[0020] The cable end 3 has a drive cavity 302. The fan blade 1001 is rotatably installed in the drive cavity 302. The air inlet 301 is connected to the drive cavity 302 and is located on one side of the drive cavity 302, so that compressed gas enters the drive cavity 302 through the air inlet 301. Since the air inlet 301 is located on one side of the middle of the drive cavity 302, the gas can blow the fan blade 1001 to rotate.

[0021] Both ends of the threading rod 1 are fixedly installed with threaded connectors 2, and one end of the threading head 3 is fixedly installed with a threaded sleeve 4. The threaded connectors 2 on the threading rod 1 can be threaded into the threaded sleeve 4. The threaded connectors 2 and the threaded sleeve 4 are matching connecting parts. The threading head 3 can be threaded onto the threaded connectors 2 at one end of the threading rod 1 through the threaded sleeve 4.

[0022] The conical head 6 has an air outlet 8 inside, and the air outlet 8 is connected to the drive cavity 302. The air outlet 8 is used for exhaust and also facilitates blowing away blockages in the conduit.

[0023] One end of the wire thread 3 is fixedly installed with a fixing ring 9, which facilitates the hanging of the wire.

[0024] Working Principle: In use, the threaded end 3 is threaded onto the threaded connector 2 at one end of the threaded rod 1 via the threaded sleeve 4. The other end of the threaded rod 1 is connected to an air pump. The threaded end 3 and the threaded rod 1 are manually inserted continuously from one end of the conduit. Simultaneously, compressed gas is delivered into the threaded rod 1 by the air pump and transmitted through the air passage 101 within the threaded rod 1. The compressed gas enters the drive chamber 302 through the air inlet 301. Since the air inlet 301 is located on one side of the middle of the drive chamber 302, the compressed gas can drive the fan blade 1001 to rotate. The fan blade 1001 drives the drive gear 1002 to rotate. The drive gear 1002 drives the crown gear 5 to rotate, the crown gear 5 drives the conical head 6 to rotate, and the conical head 6 drives the scraper 7 to rotate. When there is an obstacle in the conduit, the conical head 6 drives the scraper 7 to rotate, which, in conjunction with the manual operation of the threading rod 1, can be inserted and withdrawn into the conduit to clear the obstacle and unclog the pipe, making it easier for the threading rod 1 to pass through. Gas can be discharged through the air outlet 8 on the conical head 6, which also helps to blow away blockages in the conduit. When the threading head 3 passes through the other end of the conduit, the wire can be tied to the fixing ring 9 on the threading head 3 with a cable tie or the like, and then the threading rod 1 can be pulled out to insert the wire into the conduit.

[0025] It should be noted that because the force of the gas blowing the fan blade 1001 to rotate is limited, this device is not suitable for conduits that are completely blocked by hard blockages.

[0026] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
