DETAILED DESCRIPTION

[0024] 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. Specific embodiment:

[0026] like Figure 1-5As shown, a building electrical wire-laying device comprises a frame 1 and a universal wheel 2 with a brake arranged at the lower end of the frame 1, a wire-laying roller 3 with adjustable length is arranged on the frame 1, a horizontal plate 4 is fixedly connected inside the frame 1, a first slider 5 slides on the horizontal plate 4, a first vertical plate 6 is fixedly connected to the frame 1, a second vertical plate 7 is fixedly connected to the first slider 5, and the wire-laying roller 3 is arranged between the first vertical plate 6 and the second vertical plate 7; the wire-laying roller 3 comprises a first cylinder 31 and a second cylinder 32 sliding inside the first cylinder 31, a limiting groove 311 is provided inside the first cylinder 31 along the length direction, a limiting block 321 matched with the limiting groove 311 is provided at one end of the second cylinder 32 located inside the first cylinder 31, and the limiting block 321 slides in the limiting groove 311, so that the first cylinder 31 and the second cylinder 32 can rotate synchronously, and the length of the wire-laying roller 3 can be adjusted telescopically without affecting the release or winding of the cable.

[0027] like Figure 1-5 As shown, the first cylinder 31 is fixedly connected to the first disc 33 at one end away from the second cylinder 32, and the first disc 33 is fixedly connected to the first connecting rod 34 that penetrates and rotates on the first vertical plate 6 at one side away from the first cylinder 31, and the first connecting rod 34 is fixedly connected to the handle 35 at one end located on the first vertical plate 6 away from the first disc 33; the second cylinder 32 is fixedly connected to the second disc 36 at one end located outside the first cylinder 31, and the second disc 36 is fixedly connected to the second connecting rod 37 that penetrates and rotates on the second vertical plate 7 at one side away from the second cylinder 32. By rotating the handle 35, the pay-off roller 3 can be rotated to release the cable or reel in the cable.

[0028] like Figure 1-5 As shown, a positioning mechanism 8 is provided between the second vertical plate 7 and the horizontal plate 4, and the positioning mechanism 8 is used to keep the length of the pay-off roller 3 fixed after adjusting the length of the pay-off roller 3; the positioning mechanism 8 includes a positioning plate 81 fixedly connected to the side of the second vertical plate 7 away from the first vertical plate 6, and an insertion rod 82 is inserted on the positioning plate 81; it also includes a plurality of positioning holes 83 that are evenly spaced along the length direction of the horizontal plate 4 on the horizontal plate 4, the positioning holes 83 are adapted to the insertion rod 82, and the lower end of the insertion rod 82 can just be inserted into the positioning hole 83. When it is necessary to adjust the length of the pay-off roller 3, pull out the rod 82 from the positioning plate 81, pull the first slider 5 to change the position between the first vertical plate 6 and the second vertical plate 7, and then change the total length of the first cylinder 31 and the second cylinder 32. Finally, the length of the pay-off roller 3 is adjusted, and then the rod 82 is passed through the positioning plate 81 and inserted into the positioning hole 83 at a suitable position. When the cable is wound, the starting end of the cable winding is on the first cylinder 31. If the cable is too long, the length of the pay-off roller 3 can be adjusted in time to change the maximum length of the cable wound by the device, thereby improving the applicability of the device.

[0029] like Figure 1-5As shown, a building electrical wire-laying device also includes a wire-management mechanism 9 that does not affect the use after adjusting the length of the wire-laying roller 3. The wire-management mechanism 9 is used to make the cables more evenly distributed on the wire-laying roller 3 when winding the cables. When releasing the cables, if the wire-management mechanism 9 is used, the lowering position of the cables can also be controlled. The wire-management mechanism 9 includes a mounting frame 91 fixedly connected to the frame 1 and a second slider 92 sliding on the mounting frame 91. The upper end surface of the second slider 92 is fixedly connected to a wire-management frame 93. Two wire-management groups 94 are arranged in the wire-management frame 93. The wire-management group 94 includes a plurality of wire-management shafts 941 rotatably connected to the wire-management frame 93. The two wire-management groups 94 are parallel to each other and inclined. The cable runs through the two wire-management groups 94. When the wire-laying roller 3 is rotated and the cable is wound, the cable can be confined between the wire-management frames 93 to reduce the offset distance of the cable.

[0030] like Figure 1-5 As shown, the cable management mechanism 9 also includes a connecting block 95 fixedly connected to the side wall of the mounting frame 91, and a tension spring 96 is connected between the connecting block 95 and the second slider 92. When the tension spring 96 is in a normal state, corresponding to the maximum length of the pay-off roller 3, a pull rope 97 is fixedly connected to the side of the second slider 92 away from the connecting block 95. Since the starting end of the cable is wound on the first cylinder 31 when it is wound, the pull rope 97 is pulled to stretch the tension spring 96, and the second slider 92 slides to a position close to the first cylinder 31, passes the cable through the cable management shaft 941, and winds the starting end of the cable on the first cylinder 31. Turn the handle 35, and in the process of winding the cable, according to the cable on the first cylinder 31 and the second cylinder 3 2, pull or loosen the drawstring 97 so that the cables can be more evenly distributed on the pay-off roller 3. When the drawstring 97 is loosened, the second slider 92 can slide close to the connecting block 95 due to the tension of the tension spring 96 to restore the deformation, so that the cables can approach the second cylinder 32 and be wound thereon; because when the tension spring 96 is in a normal state, it corresponds to the maximum length of the pay-off roller 3, so even if the length of the pay-off roller 3 is adjusted, the wire management mechanism 9 can still be used flexibly, so that the wire management frame 93 can still correspond to the winding area of ​​the pay-off roller 3 and is not affected by changing the length of the pay-off roller 3; conversely, when paying out the wire, the lowering position of the cable can also be changed by pulling or loosening the drawstring 97.

[0031] like Figure 1-5 As shown, the side wall of the mounting frame 91 is also fixedly connected to a positioning ring 98, and a pull rope 97 is passed through the positioning ring 98 to facilitate pulling the pull rope 97. The pull rope 97 is fixedly connected to one end away from the second slider 92 with a grip ball 99. Holding the grip ball 99 makes it convenient for the staff to pull the pull rope 97 and can also prevent the pull rope 97 from falling off the positioning ring 98.

[0032] The working principle of a building electrical wire-releasing device in this embodiment is as follows: when in use, pull the pull rope 97 to slide the second slider 92 to a position close to the first cylinder 31, then pass the cable through the cable management shaft 941, reel the starting end of the cable onto the first cylinder 31, turn the handle 35, and during the cable reeling process, pull or loosen the pull rope 97 according to the distribution of the cable on the first cylinder 31, so that the cable can be distributed more evenly on the wire-releasing roller 3. Initially, reel the cable onto the first cylinder 31, and if the cable is found to be too long, Or calculate in advance how long the cable is required and need to change the length of the pay-off roller 3, pull out the plug rod 82, pull the first slider 5 to change the position between the first vertical plate 6 and the second vertical plate 7, and then change the total length of the first cylinder 31 and the second cylinder 32, then insert the plug rod 82 through the positioning plate 81 and into the positioning hole 83 at the appropriate position, and the length adjustment of the pay-off roller 3 is completed, and then the cable is reeled up from the second cylinder 32; when paying out the cable, the lowering position of the cable can also be changed by pulling or loosening the pull rope 97.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
