DETAILED DESCRIPTION
[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example
[0028] Reference Figures 1 to 5, is an embodiment of the utility model, which provides a portable wiring device for municipal engineering construction, mainly including a drainage pipe 1 pre-buried in the ground and a guide assembly 2 for pulling the cable into the drainage pipe 1. Among them, the guide assembly 2 includes a guide bar 21 fixed on the inner wall of the drainage pipe 1, and the two ends of the guide bar 21 penetrate to form a cavity, and the lower end of the cavity penetrates the guide bar 21 to form an insertion port 211, and the insertion port 211 is connected to the cavity but has a smaller diameter than the cavity, so that the slider 22 inserted and slidably connected in the cavity is supported. Among them, a connecting piece 23 is fixed in the middle of the lower end surface of the slider 211, and the connecting piece 23 passes through the insertion port 211, and the connecting piece 23 can be a rod body with a thread on the surface, and is threadedly connected to the traction end of the wire mesh sleeve sleeved on the cable through the connecting piece 23. The connecting piece 23 can also be a hook, which is connected to the traction end of the wire mesh sleeve on the cable through the hook.
[0029] In addition, a pull rope 24 is also provided in the cavity of the guide bar 21, and the pull rope 24 includes a first cable 241 and a second cable 242. One end of the first cable 241 is fixed to the middle of one side of the slider 22, and one end of the second cable 242 is fixed to the middle of the other side of the slider 22. The two side walls of the inner cavity of the guide bar 21 at both ends are fixed with a rotating rod 4 through bearings. One end of the first cable 241 and the second cable 242 away from the slider 22 is sleeved and wound on the rotating rod 4 to form a third cable 243, and one end of the third cable 243 is fixed to the shielding assembly 3. The user pulls the shielding assembly 3 to make the pull rope 24 pull the slider 22 to move along the guide bar 21, thereby allowing the cable to travel through the drain pipe 1.
[0030] In addition, the shielding component 3 includes an insert block 32 inserted into the inner cavity of the guide bar 21, the lower part of the insert block 32 corresponds to the insertion port 211, the outer baffle 31 is fixed to the outer surface of the insert block 32, and the inner surface of the outer baffle 31 fits the end surface of the guide bar 21. When the cable passes through the drain pipe 1, the two ports of the drain pipe 1 need to be filled with cement for sealing, but the cable will age over time. After aging, the cable or the cable failure needs to be taken out for maintenance or replacement. At this time, if the cement enters the guide bar 21, the guide component 2 cannot be used. For this reason, the shielding component 3 is used to seal the two ends of the guide bar 21, so that the cement will not enter the guide bar 21 when sealing the two ends of the drain pipe 1, and cause the travel channel of the guide bar 21 to be blocked.
[0031] In addition, first grooves 34 are provided on both sides of the inner surface of the inner insert block 32, and second grooves 34 connected to each other are provided on the opposite side of the inner surface of the two first grooves 34. After the user pulls out the outer baffle 31, the fingers of both hands can be inserted into the first grooves 34 and press the second grooves 34, and then the user pulls the pull rope 24 outward to move the cable along the guide bar 21.
[0032] In addition, in order to prevent the inner insert block 32 from being easily separated from the guide bar 21 or creating a gap due to the lack of a limit, which may cause the cement to enter the guide bar 21 or the gap between the guide bar 21 and the outer baffle 31 when the port of the drainage pipe 1 is filled with cement, making it difficult to pull out the outer baffle 31. The guide bar 21 is penetrated by a first plug hole 33 on both sides, and the inner insert block 32 is provided with a second plug hole 38 corresponding to the first plug hole 33 on both sides. The aperture of the first plug hole 33 is smaller than that of the second plug hole 38, so that there is a surplus space after the plug rod 36 is inserted from the first plug hole 33 into the second plug hole 38. In order to prevent the plug rod 36 from moving out of the first plug hole 333 and falling off, an insert plate 37 that fits tightly with the inner wall of the second plug hole 38 is fixed on one end face of the plug rod 36 located at the second plug hole 38. When the insertion rod 36 is pulled outward, the insertion rod 36 is removed from the second insertion hole 38 , and the insertion plate 37 is embedded in the circular groove provided on the inner wall of the guide bar 21 , so that the outer baffle plate 31 and the inner insertion block 32 can be taken out from the guide bar 21 .
[0033] It should be noted that one end of the rotating rod 4 can be extended to the outside and connected to a motor or a hand wheel to collect the redundant third cable 243.
[0034] Working principle: The user pulls out the outer baffle 31 to move the inner block 32 out of the guide bar 21, and then the third cable 243 pulls the rotating rod 4 to rotate, and then pulls the second cable 242 or the first cable 241 to move, so that the slider 22 moves in the direction of the user's pulling, and then the user connects the traction end of the wire mesh sleeve on the cable to the connecting piece 23, and pulls another convenient outer baffle 31 to make the cable pass through the drainage pipe 1. The difference from the traditional plug-in method is that the present application miniaturizes the traction component and arranges it in the drainage pipe 1, and the construction personnel do not need to carry too much matching equipment, which is more convenient for the construction personnel to carry out construction.
[0035] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values (e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature or number or position of the discrete element may be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model.
