Description

Technical Field

[0001] This utility model relates to the technical field of wire straighteners, and in particular to a wire straightener that straightens bent copper wires. Background Technology

[0002] During the installation and construction of high and low voltage electrical switchgear, the secondary wiring process requires accurate wiring, simple paths, reasonable layout, horizontal and vertical alignment, aesthetic appeal, and secure and clear installation. The selected secondary conductors should be copper wire with plastic insulation and a voltage of not less than 500V. To ensure horizontal and vertical alignment, the traditional straight-line method involves manual pulling. Because copper wire has ductility, manual pulling can easily cause the wire diameter to thin. Although this is not outwardly noticeable, it does not meet design requirements and poses certain defects and potential hazards. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the present invention provides a wire straightener that is easy to straighten copper wire and does not easily cause the copper wire to change diameter.

[0004] This utility model provides a wire straightener that straightens bent copper wires using the following technical solution: A wire straightener for straightening bent copper wires includes a handheld cylinder with three sets of guide wheels installed inside. The three sets of guide wheels are spaced 120 degrees apart along the circumference of the handheld cylinder. Each set of multi-directional wheels has multiple guide wheels along the length of the handheld cylinder. The center positions of the three guide wheels in the same position along the axial direction of the handheld cylinder form a straightening hole for the copper wire to pass through.

[0005] Optionally, a Y-shaped long strip is fixed inside the handheld tube. A Y-shaped groove is opened on the Y-shaped long strip. The Y-shaped groove is set along the length of the handheld tube. The Y-shaped groove includes three mounting grooves spaced 120 degrees apart in the circumferential direction of the handheld tube. Each set of guide wheels corresponds to one mounting groove. A shaft is rotatably connected to the center position of the guide wheel. The shaft is fixed to the groove wall of the mounting groove.

[0006] Optionally, a rubber sleeve is fixed to the outer wall of the handheld cylinder.

[0007] Optionally, a funnel-shaped feed tube is provided at one end of the handheld cylinder.

[0008] Compared with the prior art, the present invention has the following technical effects: The wire straightener of this utility model has a simple structure. It changes the traditional method of manually pulling the wire to a guide wheel to straighten the copper wire, effectively preventing the wire diameter from becoming thinner due to pulling, meeting process requirements, and ensuring the safe and stable operation of power distribution equipment.

[0011] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 The present invention will be described in further detail below.

[0012] Embodiment 1 of this utility model Reference Figures 1-3 This utility model discloses a wire straightener for straightening bent copper wires, comprising a handheld cylinder 1, a Y-shaped elongated block 2, and a guide wheel 3. The Y-shaped elongated block 2 is fixed to the inner wall of the handheld cylinder 1, and its length is equal to that of the handheld cylinder 1. A Y-shaped groove 21 is formed on the Y-shaped elongated block 2, which is arranged along the length direction of the handheld cylinder 1. The Y-shaped groove 21 includes three mounting slots 211, which are spaced 120 degrees apart in the circumferential direction of the handheld cylinder 1.

[0013] Each mounting slot 211 is provided with multiple guide wheels 3. The multiple guide wheels 3 in each mounting slot 211 form a group. In this embodiment, a group of guide wheels 3 is provided with four guide wheels 3. A shaft 4 is provided at the center of the guide wheel 3. The guide wheel 3 and the shaft 4 are rotatably connected. The shaft 4 is fixed to the groove wall of the Y-shaped slot 21. The guide wheels 3 in the three mounting slots 211 are aligned along the length of the handheld cylinder 1. The center of the three guide wheels 3 in the three groups of guide wheels 3 located at the same position along the axial direction of the handheld cylinder 1 forms a straightening hole 5. The straightening hole 5 has the same diameter as the copper wire. The bent copper wire is straightened after passing through the straightening hole 5.

[0014] A rubber sleeve 6 is attached to the outer wall of the handheld cylinder 1. The rubber sleeve 6 increases friction, making it more stable when the operator grips it. When straightening a bent copper wire, the operator holds the handheld cylinder 1 with one hand and inserts one end of the bent copper wire into the center of the three sets of guide wheels 3 with the other hand. The bent copper wire gradually passes through the three sets of guide wheels 3. When the copper wire passes through the three sets of guide wheels 3, the bent copper wire is straightened.

[0015] The wire straightener of this utility model has a simple structure. It changes the traditional method of manually pulling the wire to straighten it by using guide wheels 3 to straighten the copper wire, effectively preventing the wire diameter from becoming thinner due to pulling, meeting process requirements, and ensuring the safe and stable operation of power distribution equipment.

[0016] Embodiment 2 of this utility model Reference Figure 4 The difference from Embodiment 1 is that a feed cylinder 7 is provided at one end of the handheld cylinder 1. The end of the feed cylinder 7 near the handheld cylinder 1 is welded and fixed to the Y-shaped elongated block. The feed cylinder 7 is trumpet-shaped, with a smaller end near the handheld cylinder 1 and a larger end away from the handheld cylinder 1. The smaller end of the feed cylinder 7 is aligned with the center position of the three sets of guide wheels 3. The larger end of the copper wire spool feed cylinder 7 enters the feed cylinder 7 and then enters the straightening circular hole 5 of the Y-shaped groove 21.

[0017] When one end of the bent copper wire is inserted into the handheld cylinder 1, it is not necessary to align the end of the copper wire with the straightening hole 5. By providing the feed cylinder 7, it is convenient to insert the copper wire to be straightened into the straightening hole 5. A connecting rod 71 is fixed on the outer wall of the feed cylinder 7, and the end of the connecting rod 71 near the handheld cylinder 1 is fixed to the handheld cylinder 1.

[0018] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
