[

The lower semicircular protrusion 321 serves to surround and support the lower end side of the rope passing through the lower end of the lower mounting plate 32 and to provide a place where the lower protrusion 323 is formed .

The lower plate portion 322 corresponds to the upper plate portion 312 or is closely contacted with the lower plate portion 322 to tightly close the upper mounting plate 31 and the lower mounting plate 32. The lower protrusion 323 may be formed by engaging the upper mounting plate 31 and the lower mounting plate 32 together with the lower semicircular protrusion 321 To secure the rope.

It is preferable that the lower protrusion 323 protrude from the inner circumferential surface of the lower semicircular protrusion 321 toward the center of the rope so that the lower protrusion 323 can be uniformly and firmly stuck on the outer circumferential surface of the rope. .

The upper mounting plate 31 further includes a pair of upper fastening holes 314 horizontally penetrating both sides of the upper mounting plate 31. The lower mounting plate 32 is horizontally pierced on both sides of the lower mounting plate 32 And a pair of lower fastening holes 324 formed in the upper and lower portions.

The upper fastening hole 314 is threaded and fastened to the post so that the upper mounting plate 31 can be firmly fixed to the outer surface of the post.

The lower fastening hole 324 is formed to have an elongated elongated shape so that the lower fastening hole 324 is screwed into the post and fastened to the lower mounting plate 32. When the upper mounting plate 31 is fixed, So that the lower mounting plate 32 can be fixed with its upper and lower positions adjusted according to the thickness of the rope.

The upper mounting plate 31 further includes a pair of upper spiral holes 315 which are respectively formed to penetrate through the pair of upper flat plate portions 312 and have an inner peripheral surface formed with threads, The mounting plate 32 includes a pair of lower spiral holes 325 formed to penetrate vertically through the pair of lower flat plate portions 322 corresponding to the upper spiral holes 315, The tension holding device further includes a pair of pressing bolts 33 screwed to the upper spiral hole 315 and the lower spiral hole 325.

The pressing bolt 33 is screwed to the upper spiral hole 315 and the lower spiral hole 325 so that the lower flat plate portion 322 is pressed against or closely adjacent to the upper flat plate portion 312 The upper mounting plate 31 and the lower mounting plate 32 are coupled in a compressed state so that the upper semicircular protrusion 311 and the lower semicircular protrusion 321 securely fix the rope to the inside thereof .

When one pressing bolt 33 is fastened from the upper side to the lower side and the other one is fastened from the lower side to the upper side, the pressing bolts 33, It is minimized that the pressing bolt 33 is unraveled by an external force or vibration while the bolt 33 presses the rope more evenly.

5 to 8 are views showing the installation state of the tension holding device according to the present invention. As shown in the figure, the tension holding device 3 according to the present invention is mounted on both side surfaces of the post 1 in correspondence with the through holes 1a, and the end portion of the rope 2 is fixed to one side And the end of the rope 2 is engaged with and fixed to the through hole 1a while being inserted into the through hole 1a.

The posts (1) are known to have at least one through hole (1a) penetrating horizontally and fixed at a plurality of spaced apart from each other on the ground. Usually, the posts 1 are made of wood. The through hole (1a) serves to provide a place where the end of the rope (2) is fitted.

The rope 2 is formed to be long and is connected to a long hole passing through the through hole 1a of each of the posts 1 to divide the post 1 and the post 1 It plays a role.

When the rope 2 having such a configuration is sagged, the installer separates the lower mounting plate 32 from the portion of the rope 2 where the sagging occurs, pulls the rope 2 to one side, The lower mounting plate 32 is pressed against the upper mounting plate 31 by the pressing bolt 33 and then the lower mounting plate 32 is fixed to the post 1, So that the tension of the belt can easily be controlled.

9 is an enlarged longitudinal sectional view of the main part showing another state of installation of the tension holding device according to the present invention. As shown in the figure, in the present tension holding device, the rope 2 is cut into a plurality of pieces in accordance with the distance between the posts 1 and the posts 1, and between the posts 1 and the posts 1, .

The rope 2 is cut into a plurality of pieces and the one end and the other end of the rope 2 are inserted into the through hole 1a of one post 1 and the through hole 1a of the other post 1 on the one side thereof And the post 1 and the post 1, respectively, so that the installation is simple and the tension can be easily adjusted when the sag occurs.

That is, when the rope 2 is deflected, the installer separates the lower mounting plate 32 with respect to the rope 2 which is deflected, pulls the rope 2 to one side, 32 is pressed against the upper mounting plate 31 by the pressing bolt 33 and then the lower mounting plate 32 is fixed to the post 1 to adjust the tension of the rope 2 This is easy.

As described above, the present tension holding device can be used smoothly to adjust and maintain the tensile force of a plurality of ropes 2, which are installed separately between the posts 1 and the posts 1.
