Since there is no return force after the tension tensioner tightens the metal signal line, it may cause the metal signal line itself to break or the connection between the metal signal line and the tension tensioner to break, which increases the maintenance cost of the electronic fence. In view of the above problems, a tension-type electronic fence is proposed to solve the above problems. Utility Model Content

[0019] By adopting the above technical solution, it is possible to wrap the metal wire around the outside of the vertical pole, and provide a space for the metal wire to wrap around and pass through.

[0020] The tension-type electronic fence is constructed by installing a connecting frame on a vertical pole, passing a metal wire through the connecting frame and surrounding it on the outside of the vertical pole, reserving a certain length margin for the portion of the metal wire surrounding the outside of the vertical pole, and adding a locking ball and a locking cone at the connection between the connecting frame and the metal wire.

[0028] See also Figure 1 In this embodiment, a tension-type electronic fence includes a terminal pole 1 and a vertical pole 4 for support and a metal wire 3 fixed between the terminal pole 1 and the vertical pole 4, wherein the vertical pole 4 is distributed between two adjacent terminal poles 1 for supporting the metal wire 3.

[0029] Preferably, a terminal rod insulator 2 is fixedly mounted on the side of the terminal rod 1 for fixing the metal wire 3 on the terminal rod 1 .

[0030] Furthermore, a tensioning device for tightening the metal wire 3 is disposed outside the metal wire 3 , and a force-returning device for pulling the metal wire 3 back is disposed on the vertical pole 4 .

[0031] The present application can tension and install the metal wire 3 through a tensioning device located outside the metal wire 3, and at the same time, through a rebound device located on the vertical pole 4, the metal wire 3 has the ability to relax, thereby reducing the phenomenon of the metal wire 3 being directly broken due to excessive tension under stress.

[0032] See also Figure 2 In this embodiment, the tensioning device includes a mounting shell 5 located outside the metal wire 3, the middle part of the mounting shell 5 is oval and used for curling and storing the metal wire 3, and both ends of the mounting shell 5 are penetrated by openings, so that the mounting shell 5 can be passed through by the metal wire 3 to complete the installation;

[0033] The tensioning device also includes a rotating wheel 6 rotatably mounted on the inner wall of the mounting shell 5, on which a connecting tube 7 and a tightening rod 8 are fixedly mounted, wherein the connecting tube 7 is located in the middle of the rotating wheel 6 and passes through and is connected to both ends of the rotating wheel 6, and the tightening rod 8 includes two symmetrically arranged at both ends of the connecting tube 7.

[0034] Such a design enables the metal wire 3 to be rotated and tightened by the two tightening rods 8 under the rotation of the rotating wheel 6, thereby increasing the tension of the metal wire 3.

[0035] In order to drive the rotating wheel 6 to rotate and lock, an adjusting bolt 9 for pulling the rotating wheel 6 is threadedly installed on the inner wall of the mounting shell 5. The adjusting bolt 9 is located at one end outside the mounting shell 5 and has a handle for the user to rotate and adjust the adjusting bolt 9 externally.

[0036] Furthermore, a connecting pin 10 is fixedly installed on the inner wall of the connecting pipe 7, and a groove for the connecting pin 10 to slide into and slide is opened on the outer wall of the adjusting bolt 9. It is worth noting that a nut can also be installed on one end of the adjusting bolt 9 to lock the rotation of the adjusting bolt 9.

[0037] In a specific implementation, the adjusting bolt 9 is connected to the connecting pin 10 by relative sliding, so that the connecting tube 7 can rotate synchronously with respect to the adjusting bolt 9 and can slide relative to the adjusting bolt 9 to always rotate in contact with the inner wall of the mounting shell 5 .

[0038] Under the traction of the adjusting bolt 9, the tension of the metal wire 3 can be adjusted, and at the same time, the nut on one side of the adjusting bolt 9 is locked, so that the metal wire 3 can be tightened and adjusted.

[0039] See also Figure 3-4 In this embodiment, the rebound device includes a connecting frame 12 located outside the vertical pole 4, a locking cone 14 located inside the connecting frame 12, and a locking ball 16 fixed to the outside of the metal wire 3. The connecting frame 12 includes two symmetrically arranged on the vertical pole 4, which are used to connect the metal wires 3 on both sides of the vertical pole 4.

[0040] Preferably, a pole insulator 11 is fixedly installed on the outside of the pole 4, and the connecting frame 12 is fixedly connected to the pole insulator 11 in an arc shape, so that the connecting frame 12 can be arranged on the outside of the pole 4;

[0041] Furthermore, the longitudinal cross-section of the connecting frame 12 is U-shaped and faces the front opening of the vertical pole insulator 11. The locking cone 14 is fixedly installed in the front opening of the connecting frame 12. One end of the locking cone 14 is a conical end 15, and the conical end 15 is broken into several petals that can be expanded.

[0042] In a specific implementation, the tapered end 15 is composed of a plurality of petals connected to each other. Since the petals are broken from each other, the tapered end 15 can open while overcoming its own elastic force.

[0043] In this embodiment, the locking ball 16 abuts against the conical end 15, and the locking ball 16 can prevent the metal wire 3 from moving relative to the locking cone 14. At the same time, under stress, the metal wire 3 can pull the locking ball 16 to squeeze the conical end 15 and deform it, so that the metal ball 16 can pass through the outside of the locking cone 14.

[0044] It is worth noting that a wire groove 13 is provided on one end of the connecting frame 12 that is attached to the vertical pole insulator 11. The wire groove 13 can facilitate the passage of the metal wire 3, so that a part of the metal wire 3 can be reserved to cross the two connecting frames 12 and extend to the rear side of the vertical pole 4, and when the metal wire 3 is pulled, it is tightened to the outside of the vertical pole 4, ensuring that the metal wire 3 can be relaxed and opened relative to the vertical pole 4 and the terminal pole 1.

[0045] The working principle of the above embodiment is:

[0046] By fixing the locking ball 16 on the outside of the metal wire 3 and passing the metal wire 3 through the two connecting frames 12 in an interlaced manner, the locking ball 16 on the metal wire 3 can respectively abut against the locking cones 14 in the two connecting frames 12. At this time, the tensioning device on the metal wire 3 is adjusted, and the adjusting bolt 9 located outside the mounting shell 5 is rotated. The adjusting bolt 9 rotates relative to the mounting shell 5, so that the connecting pipe 7 located inside the mounting shell 5 rotates synchronously with the adjusting bolt 9. At this time, the rotating wheel 6 and the tightening rod 8 fixedly connected to the connecting pipe 7 rotate relative to the metal wire 3, so that the metal wire 3 is wound around the outside of the tightening rod 8 to complete the tightening installation of the metal wire 3;

[0047] When the metal wire 3 is acted upon by an external force, the metal wire 3 is pulled, and the locking ball 16 at one end of the metal wire 3 exerts force on the locking cone 14. The locking ball 16 squeezes the conical end 15 at the end of the locking cone 14 under the pulling force, and deforms and opens. At this time, the locking ball 16 can pass through the locking cone 14 and slide to the outside of the connecting frame 12, and the metal wire 3 reserved outside the vertical pole 4 is tightened relative to the vertical pole 4. This allows the metal wire 3 connected between the connecting frame 12 and the terminal pole 1 to be extended, reducing the phenomenon of direct breakage under force.
