Abstract
Description
Technical Field
[0001] This utility model relates to a handheld wire laying device, and more particularly to a wire laying device for building construction. Background Technology
[0002] During construction, it's necessary to lay out cables such as fiber optics, electrical cables, and power cords, requiring a cable laying device. Since fiber optics and power cords are relatively small, the corresponding cable laying devices are also small, mostly handheld, suitable for most laying environments. Existing conventional handheld cable laying devices generally consist of a stand and a rotating body / shaft. The rotating body / shaft is used to fix the winding drum, which is a cylindrical object with the cable wound on it. The dimensions of the rotating body / shaft are generally fixed, thus the corresponding winding drum size is also fixed, resulting in poor versatility and compatibility of the cable laying device. Summary of the Invention
[0003] This utility model provides a line-laying device for building construction, which solves the problem of poor compatibility of existing line-laying devices.
[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a wire laying device for building construction, including a bracket and a rotating body for fixing the winding drum. The rotating body is composed of a rotating shaft, a disc, several eccentric plates and a large gear disc. The rotating shaft is rotatably mounted on the bracket. The disc is vertically fixed to one end of the rotating shaft. The large gear disc is rotatably sleeved on the rotating shaft. Several secondary rotating shafts are also circumferentially distributed on the disc. A gear that meshes with the large gear disc is coaxially fixed on the secondary rotating shaft. The eccentric plates are sleeved on the secondary rotating shafts and relatively fixed. A locking plate is also rotatably provided on the disc. One side of the locking plate is provided with a locking tooth that can mesh with the large gear disc. The disc is provided with an elastic element that drives the locking plate to deflect to one side of the large gear disc. The large gear disc and the eccentric plates are distributed on both sides of the disc.
[0005] The rotating body in this invention is used to fix and install the winding drum. More specifically, the circumcircle defined by all the eccentric plates is the inner diameter of the suitable winding drum. Therefore, by adjusting the diameter of this circumcircle, this invention can be adapted to winding drums of different sizes. The specific adjustment method is as follows: First, the locking plate needs to be flipped outward to separate it from the large gear plate. Then, by rotating the large gear plate in both directions, all the gears will rotate synchronously, causing all the eccentric plates to deflect outward or inward synchronously. When all the eccentric plates are in contact with the inner diameter of the winding drum, the locking plate is flipped again to engage with the large gear plate. At this time, the large gear plate is fixed relative to the disc, and the eccentric plates are also fixed in the deflected position. The winding drum is then fixed by the rotating body.
[0006] Furthermore, an outer eccentric plate is fixed on the secondary rotating shaft, with the eccentric plate positioned between the outer eccentric plate and the disc. A torsion spring is sleeved on the secondary rotating shaft, with its two ends fixed relative to the secondary rotating shaft and the eccentric plate, respectively. The eccentric plate can spring back to the same orientation as the outer eccentric plate under the action of the torsion spring. Through the above technical solution, this invention allows the large gear disc to continue rotating even when the eccentric plate abuts against the inner diameter of the winding drum. This causes a certain relative rotation between the secondary rotating shaft and the eccentric plate, and the torsion spring is also twisted. The torque generated by the torsion spring can be converted into an expanding force of the eccentric plate on the winding drum. Simultaneously, the outer eccentric plate continues to rotate, making the circumscribed circle defined by the outer eccentric plate larger than the inner diameter of the winding drum. Thus, the outer eccentric plate and the disc can provide a limiting effect on both ends of the winding drum, resulting in a superior fixing effect.
[0007] Furthermore, a rubber sleeve is fitted over the eccentric plate, and the rubber sleeve has several anti-slip protrusions. The rubber sleeve and the anti-slip protrusions are designed to increase the static friction between the eccentric plate and the winding drum, ensuring that the winding drum remains fixed relative to the rotating body.
[0008] Therefore, this utility model has the following characteristics compared with the prior art: 1. The rotating body in this utility model is used to fix and install the winding drum. More specifically, the outer circle defined by all the eccentric plates is the inner diameter of the suitable winding drum. Therefore, by adjusting the diameter of the outer circle, this utility model can be adapted to winding drums of different sizes. The rotation angle of the large gear plate can be quickly adjusted by rotating the rotation angle of the large gear plate. 2. The outer eccentric plate and the disc can limit the two ends of the winding drum, making the fixing effect of this utility model more excellent. Attached Figure Description

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Example 1: See Figure 1 , Figure 2 A wire-laying device for construction includes a support 100 and a rotating body 200 for fixing a winding drum. The rotating body consists of a rotating shaft 210, a disc 220, five eccentric plates 230, and a large gear disc 240. The rotating shaft is rotatably mounted on the support, the disc is vertically fixed to one end of the rotating shaft, and the large gear disc is rotatably sleeved on the rotating shaft. Five auxiliary rotating shafts 250 are also circumferentially distributed on the disc. Gears 260 that mesh with the large gear disc are coaxially fixed on the auxiliary rotating shafts. The eccentric plates are sleeved on the auxiliary rotating shafts and relatively fixed. A locking plate 270 is also rotatably mounted on the disc. One side of the locking plate has a locking tooth 271 that can mesh with the large gear disc. The disc has an elastic element 272 that drives the locking plate to deflect to one side of the large gear disc. The large gear disc and the eccentric plates are located on both sides of the disc.
[0018] In this embodiment, the rotating body is used to fix and install the winding drum. More specifically, the circumcircle defined by all the eccentric plates is the inner diameter of the suitable winding drum. Therefore, by adjusting the diameter of this circumcircle, this embodiment can be adapted to winding drums of different sizes. The specific adjustment method is as follows: First, the locking plate needs to be flipped outward to separate it from the large gear plate. Then, by rotating the large gear plate in both directions, all the gears will rotate synchronously, causing all the eccentric plates to deflect outward or inward synchronously. When all the eccentric plates are in contact with the inner diameter of the winding drum, the locking plate is flipped again to engage with the large gear plate. At this time, the large gear plate is fixed relative to the disc, and the eccentric plates are also fixed in the deflected position. The winding drum is then fixed by the rotating body.
[0019] See Figure 1 , Figure 4 , Figure 5 and Figure 6An outer eccentric plate 280 is fixed on the secondary rotating shaft, with the eccentric plate positioned between the outer eccentric plate and the disc. A torsion spring 290 is sleeved on the secondary rotating shaft, with its two ends fixed relative to the secondary rotating shaft and the eccentric plate, respectively. The eccentric plate can spring back to the same orientation as the outer eccentric plate under the action of the torsion spring. In this embodiment, through the above technical solution, when the eccentric plate abuts against the inner diameter of the winding drum, the large gear disc can continue to rotate. This causes a certain relative rotation between the secondary rotating shaft and the eccentric plate, and the torsion spring is also twisted. The torque generated by the torsion spring can be converted into an expansion force of the eccentric plate on the winding drum. At the same time, the outer eccentric plate continues to rotate, making the circumscribed circle defined by the outer eccentric plate larger than the inner diameter of the winding drum. In this way, the outer eccentric plate and the disc can provide a limiting effect on both ends of the winding drum, making the fixing effect of this embodiment more excellent.
[0020] See Figure 3 The eccentric plate is fitted with a rubber sleeve 231, and the rubber sleeve has several anti-slip protrusions 232. The rubber sleeve and the anti-slip protrusions are designed to increase the static friction between the eccentric plate and the winding drum, ensuring that the winding drum is fixed relative to the rotating body.
[0021] See Figure 1 The bracket includes a connecting rod 110 and a handle 120 rotatably fitted at one end thereto, and a rotating shaft is rotatably fitted at the other end of the connecting rod.
[0022] See Figure 1 A lever 241 is fixed on the large gear plate, and a ball head 242 is provided on the lever.
[0023] See Figure 1 The locking plate is also extended to include a paddle 273, and the rotation axis of the locking plate is located between its body and the paddle.
[0024] See Figure 1 One end of the shaft is provided with a flange 211, which fits against the disc and is fixedly connected by bolts.
[0025] See Figure 1 A bearing 10 is installed between the rotating shaft and the large gear plate, and a bearing 10 is also installed between the rotating shaft and the connecting rod.
[0026] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
