[0002] At present, the electrical lines of buildings are all pre-buried in wire pipes, and steel belts are pre-placed in the wire pipes to guide the cables into the wire pipes later. The steel belts are then inserted into the pipeline from one end of the pipeline, and the steel belts are pushed to move in the pipeline until the steel belts come out from the other end of the pipeline. One end of the steel belt is then fixedly connected to the cable, and the steel belt is pulled back from the original entry end, and the cable is pulled into the pipeline to realize the threading construction.
[0003] However, for long-distance pre-buried pipelines, some electrical concealed pipes may retain dust or building materials from the construction, or debris may enter due to poor connections of the concealed pipes themselves. When threading the electrical concealed pipes, the pipes may be blocked and the cables cannot be smoothly delivered, making the threading work difficult. For this reason, we propose a threading construction device for building electrical engineering. Utility Model Content

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1:
[0027] See also Figure 1-5 The utility model provides a technical solution: a wire threading construction device for building electrical engineering, comprising a guide wire 1 and a guide head 2 arranged at the head end of the guide wire 1, a through hole is opened in the guide wire 1, a cavity 3 is opened inside the guide head 2, and the cavity 3 is connected to the through hole, the tail end of the guide wire 1 can be externally connected to a driving unit, and also includes an impact piece 4 movably arranged in the cavity 3, the impact piece 4 can extend out of the guide head 2 to conduct the blockage at the head end, and limit pieces 5 are arranged on both sides of the guide head 2, the limit pieces 5 can extend out of the guide head 2 and abut against the inner wall of the concealed pipe, and a driving unit is arranged at the end of the guide wire 1, which can drive the impact piece 4 and the limit piece 5 to move, and the driving unit is a fan, which is not drawn in the figure. The output end of the fan is connected to the end of the guide wire 1. When the guide wire 1 is connected to the fan, the fan can transport gas into the guide wire 1 when it is turned on. A connecting frame 6 is fixedly arranged on the side wall of the guide head 2, and the cable is tied to the connecting frame 6, and the guide wire 1 can drive the cable to move:
[0028] The impact member 4 includes a moving block 41 movably arranged in the cavity 3, a push rod 42 is arranged on the moving block 41, the push rod 42 movably penetrates the guide head 2 and the end portion extends to the outside of the guide head 2, a return spring 43 is arranged in the cavity 3, and the two ends of the return spring 43 are respectively fixedly connected with the moving block 41 and the bottom of the cavity 3. When the guide line 1 is connected to the fan, the fan sends air into the cavity 3 along the through hole of the guide line 1, thereby increasing the air pressure at the bottom of the moving block 41 and driving the moving block 41 to move. When the moving block 41 moves, the return spring 43 is stretched and the push rod 42 is driven to move. When the push rod 42 is extended, it can conduct the blockage in front, so that the guide head 2 can continue to move forward. When the fan is turned off, under the action of the return spring 43, the push rod 42 is reset.
[0029] A conical head 44 is fixedly provided at the end of the push rod 42. The conical head configuration makes it easier for the end of the push rod 42 to break the blockage, thereby increasing work efficiency.
[0030] Slide grooves 7 are provided on both sides of the guide head 2, and the bottom end of the slide groove 7 is connected to the cavity 3. The limit member 5 includes a support rod 51 slidably arranged in the slide groove 7, and a support spring 52 is fixedly arranged at the bottom end of the support rod 51. The bottom end of the support spring 52 is fixedly connected to the side wall of the slide groove 7. When the fan transports gas into the cavity 3, the air pressure in the slide groove 7 also increases, thereby causing the support rod 51 to move. The support rod 51 moves to the end to abut the inner wall of the concealed pipe. When the top rod 42 destroys the blockage, a certain reaction force will also act on the guide head 2, causing the guide head 2 to move. If the guide head 2 moves too much, a part of the guide wire 1 will be bent. In this case, continuing to feed the guide wire 1 will cause the guide wire 1 to be entangled in place. Therefore, positioning the guide head 2 by the support rod 51 can avoid such a situation.
[0031] A fixing plug 8 is movably installed at the end of the guide wire 1. The outer side of the fixing plug 8 is provided with a thread, and the inner wall of the end of the guide wire 1 is provided with an internal thread. When not in use, the fixing plug 8 can be used to block the end of the guide wire 1 to prevent foreign matter from entering.
[0032] In summary, when threading the wire, the end of the guide wire 1 is connected to the fan. When there is a blockage in the concealed pipe, the fan is started at this time, and the fan transports gas into the cavity 3, so that the air pressure at the bottom of the moving block 41 increases and drives the moving block 41 to move. When the moving block 41 moves, the reset spring 43 is stretched and the push rod 42 is driven to move. When the push rod 42 is extended, it can conduct the blockage in front, so that the guide head 2 can continue to move forward.
[0033] Embodiment 2:
[0034] See also Figure 6-7The main structure of the second embodiment is the same as that of the first embodiment, except that the moving block 41 includes a slider 411 slidably arranged in the cavity 3 and a rotating block 412 rotatably arranged on the slider 411, the top rod 42 is arranged on the rotating block 412, the inner wall of the cavity 3 is provided with a spiral groove 9, and a spiral strip 10 used in conjunction with the spiral groove 9 is fixedly arranged on the outer side of the rotating block 412. When the slider 411 drives the rotating block 412 to move, the rotating block 412 moves spirally in the cavity 3.
[0035] Through the above arrangement, when the slider 411 drives the rotating block 412 to move, the rotating block 412 will move in a spiral motion, thereby causing the push rod 42 to move in a spiral motion, thereby achieving a better conduction effect.
