Description

Technical Field

[0001] The utility model relates to the technical field of threading tools, in particular to a simple single-person threading tool. Background Art

[0002] The traditional construction method of cable threading is to directly thread the copper wire into the pre-buried pipe through the wire box. During the pulling process, because the wire box and the pre-buried pipe are at right angles and the interface is sharp, the threading resistance is large and the cable insulation is easily damaged, resulting in a short circuit. To avoid this situation, two people are often required to operate, one to thread the wire and the other to control the direction of the wire harness at the wire box position, which is not suitable for single-person operation.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a simple single-person threading tool is proposed to achieve a more practical purpose. Utility Model Content

[0016] 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.

[0017] See also Figures 1 to 3The utility model provides a technical solution: a simple single-person threading tool, including a vertical rod 1, an oblique support rod 4 and a roller 6, two vertical rods 1 are provided, three horizontal rods 2 are provided, and two oblique support rods 4 are provided. The vertical rod 1, the horizontal rod 2, the oblique support rod 4 and the hinged rod 3 constitute the exoskeleton of the simple single-person threading tool, and each vertical rod 1 is provided with an inner thread sleeve 8 on the rod body, the vertical rod 1 includes a screw rod 11 and a screw rod 2 12, and the inner walls of the two ends of the inner thread sleeve 8 are respectively An internal thread with opposite rotation directions is provided, and the rod body of the screw rod 11 and the screw rod 2 12 screwed into the internal thread sleeve 8 is respectively provided with external threads screwed with the internal thread sleeve 8. When the internal thread sleeve 8 is rotated, since the upper and lower ends of the internal thread sleeve 8 are provided with internal threads with opposite rotation directions, the screw rod 11 and the screw rod 2 12 screwed with the internal threads move in opposite directions, and the length of the vertical rod 1 is adjusted at the same time, so that the simple single-person threading tool can be easily inserted into the reserved wire box.

[0018] The top of the rod body of the vertical rod 1 is connected to the cross rod 2 and the oblique support rod 4, the end of the rod body of the vertical rod 1 is connected to the oblique support rod 4 through the hinge rod 3, and the connection between the vertical rod 1 and the hinge rod 3 is also connected to the cross rod 2, and the connection between the vertical rod 1, the cross rod 2, the hinge rod 3 and the oblique support rod 4 is provided with a three-head hinge seat 7, and three groups of hinge joints 71 are symmetrically distributed on the surface of the three-head hinge seat 7. The three groups of hinge joints 71 are connected to the three-head hinge seat 7 by a rotating seat 72, and the double ears of the hinge joint 71 are penetrated by screws 73. When the height of the vertical rod 1 is adjusted, the relative positions of the correspondingly connected cross rod 2, the oblique support rod 4 and the hinge rod 3 can be adjusted accordingly, and the structural feature of being connected by the rotating seat 72 allows it to be adjusted circumferentially with the surface of the three-head hinge seat 7 without being restricted.

[0020] Working principle: When using the simple single-person threading tool, first, rotate the inner thread sleeve 8. Since the upper and lower ends of the inner thread sleeve 8 are provided with inner threads with opposite rotation directions, the screw rod 11 and the screw rod 2 12 screwed to the inner threads move in opposite directions, and the length of the vertical rod 1 is adjusted at the same time, so that the simple single-person threading tool can be conveniently inserted into the reserved wire box, and the cable is passed over the drum 6 and the cable is pulled. The cable moves along the surface of the drum 6, so that the drum 6 rolls, making the threading process smoother and not stuck. Moreover, the limiting effect of the baffle 61 prevents the cable from leaving the surface of the drum 6 during the threading and traction process, making the auxiliary effect of the drum 6 invalid. By using the articulated seat of the three-head articulated seat 7, when the height of the vertical rod 1 is adjusted, the relative positions of the correspondingly connected cross bar 2, inclined support rod 4 and articulated rod 3 can be adjusted accordingly.
