Description

Technical Field

[0001] The utility model belongs to the technical field of cable laying, and particularly relates to a cable bender. Background Art

[0002] The straight line between two points is the shortest, and laying the cable in a straight line is the best way to lay it. However, for some complex terrains, it is inevitable to bend the cable, for example, when routing around a corner. However, when the current is too large, the connecting wire diameter needs to be very thick. On the one hand, it is easy to rebound after manual bending, which takes up a lot of space and is inconvenient to connect. On the other hand, the manually bent thick wire is easy to apply force to the terminal bolt to lift up when connected, which can easily lead to poor contact. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 A schematic diagram of the overall structure of a cable bender is shown;

[0023] Figure 2 A schematic diagram of the structure of the first embodiment is shown;

[0024] Figure 3 A structural schematic diagram of the second embodiment is shown. DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0026] The present application provides a cable bender. Figure 1 A schematic diagram of the overall structure of a cable bender is shown; Figure 1 In the invention, the cable bender comprises:

[0027] Two sets of rotatably connected bending parts 100, each set of bending parts 100 has a through hole 110 for the cable to pass through;

[0028] The fixing part 200 is installed between the two sets of bending parts 100. After the cables pass through the two sets of through holes 110 in sequence, the fixing part 200 can drive the two sets of bending parts 100 to rotate relative to each other around the connection and adjust the curvature of the cable, and the cable maintains the current state after bending.

[0029] After the cable passes through the two groups of through holes 110 in sequence, since the two groups of bending portions 100 are rotatably connected, the two groups of bending portions 100 can be adjusted to force the cable to bend using the two groups of bending portions 100. At the same time, the fixing parts can fix the two groups of bending portions 100 after rotation to ensure that the cable is in the current state after bending, that is, the curvature of the cable does not change, thereby avoiding cable rebound. In the present application, the fixing part 200 is used to drive the two groups of bending portions 100 to rotate to force the cable to bend, which is more labor-saving and also eliminates the hidden danger of poor contact.

[0030] Continue to see Figure 2 The bending portion 100 includes two sets of ring covers 120, which are symmetrically spliced ​​to form a through hole 110. Both ends of each bending portion 100 have fins 130, and the two sets of ring covers 120 are bolted together through the fins 130.

[0031] The two sets of ring covers 120 are detachably connected and are connected by bolts penetrating the fins 130 in the two sets of ring covers 120. During installation, there is no need for the cable to pass through the through hole 110. The two sets of ring covers 120 can be fitted on the surface of the cable and cooperate to form a through hole 110 that is sleeved on the outside of the cable. This changes the traditional cable end installation and allows direct installation in the middle of the cable, thereby improving the convenience of disassembly and installation.

[0032] Embodiment 1

[0033] This embodiment shows a design method of a fixing part 200 in a cable bender. Figure 2 A schematic diagram of the structure of the first embodiment is shown; Figure 2 In the embodiment, the fixing part 200 comprises:

[0034] Two fixing rings 210 are respectively mounted on the two sets of bending parts 100;

[0035] A screw rod 220 has a head 230 at one end. The screw rod 220 passes through two fixing rings 210 in sequence and forces the head 230 to abut against one set of fixing rings 210. The end of the screw rod 220 away from the head 230 is rotatably connected to a nut 240, which abuts against the other set of fixing rings 210.

[0036] The cable is bent manually to increase the bending degree of the cable. At this time, the screw rod 220 is out of contact with the inner walls of the two sets of fixing rings 210, leaving a movable space. At the same time, the distance between the nut 240 and the fixing ring 210 increases. At this time, the nut 240 is rotated to make the nut 240 contact the fixing ring 210 again, thereby completing the fixation of the adjusted angles of the two sets of bending parts 100.

[0037] In this embodiment, the cables need to be pre-pressed manually and operated with both hands. It is suitable for construction on open surfaces such as wall wiring and desktop wiring. The screw rod 220 and the nut 240 are detachably connected and can be removed from the bending portion 100, which is easy to replace and low-cost.

[0038] Embodiment 2

[0039] This embodiment shows another design of the fixing portion 200 in a cable bender. Figure 3 A schematic diagram of the structure of the second embodiment is shown; Figure 3 In the embodiment, the fixing part 200 comprises:

[0040] A connecting plate 230 is slidably connected to the fins 130 of one set of the bending portions 100;

[0041] A hinge rod 240, one end of which is rotatably connected to the connecting plate 230, and the other end of the hinge rod 240 is rotatably connected to the fin 130 of another group of bending parts 100;

[0042] The connecting plate 230 is driven by an external force to slide along the length track of the fin 130 and drive the two sets of bending parts 100 to rotate relative to each other around their connection.

[0043] When the connecting plate 230 is driven to slide by an external force, it can drive the hinge rod 240 to rotate, and use the hinge rod 240 to pull the two sets of bending parts 100 to rotate relative to each other, thereby changing the curvature of the cable.

[0044] Continue to see Figure 3 , the fixing portion 200 further includes:

[0045] The support plate 210 is mounted on the fin 130 and is located on one side of the connecting plate 230;

[0046] The screw rod 220 penetrates through the support plate 210 and is rotatably connected thereto, and one end of the screw rod 220 is rotatably connected to the connecting plate 230;

[0047] The screw rod 220 is driven to rotate by an external force and drives the connecting plate 230 to slide along the length track of the fin 130, and after the external force is removed, the screw rod 220 keeps the connecting plate 230 in the state caused by the external force.

[0048] When the screw rod 220 is rotated, the screw rod 220 is threadedly connected to the support plate 210, so that the connecting plate 230 can be driven to move stably along a specified trajectory. In addition, the threaded drive method can make the connecting plate 230 remain in the current state after movement to limit the cable rebound.

[0049] This embodiment adopts a single-side drive mode and can be operated with one hand. It is suitable for narrow surface construction such as wiring under a table and wiring inside a cabinet.

[0050] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
