Description

Technical Field

[0001] The utility model relates to the technical field of threading equipment, in particular to a threader for indoor decoration. Background Art

[0002] During interior decoration construction, the wires are not laid directly but are laid in pre-buried pipes to prevent moisture and heat dissipation, prevent damage to the insulation layer, avoid fire caused by short circuits, and facilitate later maintenance and replacement.

[0003] For example, the patent document with application number 202321272242.7 discloses a threader for interior decoration. The utility model discloses a threader for interior decoration, which belongs to the technical field of threading equipment. A threader for interior decoration includes a threader, a wire inlet is provided at the right end of the threader, a wire outlet is connected to the right end of the threader, and a connecting frame is provided inside the threader. In the utility model, the threaded rod is rotated according to the size of the wire to be threaded, and the threaded rod can drive the connecting frame to move through the threaded structure formed with the threader, and the movement of the connecting frame can drive the guide rod to move The guide rod moves in the guide rod groove to avoid the movement direction of the connecting frame being offset, and at the same time, the threaded rod can be prevented from rotating and driving the connecting frame to rotate together, thereby affecting the use. By adjusting the position of the connecting frame, the distance between the upper abutment wheel and the lower abutment wheel can be adjusted to adapt to lines of different sizes. The adjustment is relatively convenient, saving time and effort, improving work efficiency, and there is no need to replace the entire threader. However, when the upper and lower driving wheels are used to correct the wire material for the interior decoration threader, the threaded rod may damage the wire harness due to the downward pressure, thereby affecting the threading effect.

[0004] Therefore, in view of this, the existing structure is not enough to be studied and improved, and a threader for interior decoration is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] 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.

[0020] like Figure 1-Figure 3 As shown, a threader for interior decoration includes a threader body 1, a lower driving wheel 2 is arranged at the lower end of the inner wall of the threader body 1, and a slide groove 201 is opened on the inner wall of the threader body 1 above the lower driving wheel 2. The advantage of this arrangement is that the upper driven wheel 206 can be limited by the arrangement of the slide groove 201.

[0021] Furthermore, a sliding block 204 is slidably installed inside the slide groove 201, and a buffer spring 205 is installed inside the slide groove 201 at the lower end of the sliding block 204. The advantage of this arrangement is that, through the arrangement of the buffer spring 205, after the position of the upper driven wheel 206 is adjusted using the threaded transmission rod 202, if the downward pressure of the upper driven wheel 206 is too large, the buffer spring 205 can protect the wire by compressing the buffer wire to avoid extrusion.

[0022] Furthermore, an upper driven wheel 206 is provided at the front end of the sliding block 204, and the upper driven wheel 206 is arranged directly above the lower driving wheel 2, and a force rod 203 is installed through the surface of the upper driven wheel 206. The advantage of this arrangement is that through the arrangement of the force rod 203, multiple upper driven wheels 206 can be displaced synchronously.

[0023] Furthermore, a threaded transmission rod 202 is spirally installed in the middle of the right side surface of the threader body 1, and the threaded transmission rod 202 is rotationally connected to the force-bearing rod 203. This setting is an existing device and will not be described in detail.

[0024] Furthermore, handles 102 are provided on both sides of the upper end surface of the threader body 1, and a copper wire roller 103 is provided on the left side surface of the threader body 1, and a wire inlet 101 is provided at the front and rear ends of the threader body 1. The advantage of this arrangement is that the setting of the handle 102 makes it convenient for workers to carry the threader body 1 and move it.

[0025] like Figure 4As shown, a support block 3 is provided on the rear end surface of the threader body 1, and a rotating rod 303 is installed through the surface of the support block 3, a rotating plate 301 is installed on the surface of the rotating rod 303, and a guide wheel 302 is installed at the end of the rotating plate 301. The advantage of this arrangement is that the pulling force of the guide wheel 302 can be controlled by the arrangement of the rotating rod 303, so that the copper wire roller 103 can collect the copper wire conveniently.

[0026] Furthermore, a thread groove 304 is provided on the end surface of the rotating rod 303 , and a fixing ring 305 is spirally installed on the surface of the thread groove 304 . The advantage of this arrangement is that the rotating rod 303 can be fixed by the arrangement of the fixing ring 305 .

[0027] Working principle: When using the interior decoration threader, first, rotate the rotating plate 301 to adjust the guide wheel 302 to a suitable angle, use the fixing ring 305 to screw into the thread groove 304 and fix the rotating rod 303, rotate the threaded transmission rod 202 to press the force rod 203 downward to drive the upper driven wheel 206 to move downward along the slide groove 201, and when the distance with the lower driving wheel 2 reaches the standard for the wire harness to enter, the wire harness enters the inside of the threader body 1 through the wire inlet 101, and the lower driving wheel 2 is started to drive the wire harness to move for threading. After the threading machine is used, the lower driving wheel 2 is reversed to allow the copper wire to enter the copper wire roller 103 through the guide wheel 302 with the adjusted angle to complete the tightening. This is the working principle of the interior decoration threader.
