the first elastic part 2 is arranged on the inner ring of the revolving body formed by the rod body 13, and two ends of the first elastic part 2 are respectively pressed against the upper connecting piece 12 and the lower connecting piece 11;
and the second elastic part 3 is arranged on the outer ring of the revolving body formed by the rod body 13, and two ends of the second elastic part 3 are respectively pressed against the upper connecting piece 12 and the lower connecting piece 11.
Adopt above-mentioned technical scheme, through setting up connecting piece 12 and lower connecting piece 11, and through a plurality of body of rod 13 with last connecting piece 12 and lower connecting piece 11 at vertical direction fixed connection, install first elastic component 2 and second elastic component 3 respectively between last connecting piece 12 and lower connecting piece 11 simultaneously, when using, from down up passing first jack 111 and second jack 121 in proper order and locking with stock S, thereby realize fixing stock S in the anchor operation of back. In some rear anchoring systems, the anchor rod S often receives external force from some extreme conditions (such as earthquake and typhoon), and the outer anchoring device of the utility model is additionally installed on the anchor rod S, when the outer anchoring device is impacted by external force, the rod body 13 can generate certain bending deformation, so as to protect the anchor rod S from being damaged, specifically, when the rod body 13 receives inward destructive force, the rod body 13 can be bent inward and damaged, and through the arranged first elastic element 2, certain deformation can be generated, so as to weaken the inward destructive power of the rod body 13, and meanwhile, the first elastic element 2 is in a compression state, so as to ensure that the anchor rod S is not loosened after the rod body 13 is yielded, so as to protect the anchor rod S from being damaged; when the body of rod 13 received outside destructive power, the body of rod 13 can the incurve and suffer destruction, through the second elastic component 3 that sets up, can produce certain deformation, weakens the outside destructive power of the body of rod 13, and second elastic component 3 is in the state that compresses tightly simultaneously, guarantees not hard up of the back stock S of the body of rod 13 surrender to protection stock S does not receive the damage.
As some embodiments, referring to fig. 3 and 4, in order to facilitate the installation of the first elastic member 2 between the upper connecting member 12 and the lower connecting member 11, the technical solution adopted in this embodiment is: a first inner annular groove 112 is formed in the upper surface of the lower connector 11 where the outer ring of the first insertion hole 111 is located, a second inner annular groove 122 is formed in the lower surface of the upper connector 12 where the outer ring of the second insertion hole 121 is located, more specifically, the first inner annular groove 112 is formed in the upper surface of the lower connector 11 where the outer ring of the first insertion hole 111 and the inner ring of the rotation body formed by the rod body 13 are located, the second inner annular groove 122 is formed in the lower surface of the upper connector 12 where the outer ring of the second insertion hole 121 and the inner ring of the rotation body formed by the rod body 13 are located, and two ends of the first elastic member 2 abut against the first inner annular groove 112 and the second inner annular groove 122 respectively. By adopting the technical scheme, the first elastic part 2 can be sleeved on the anchor rod S when in use and is positioned on the inner ring of the revolving body formed by the rod body 13, and meanwhile, the two ends of the first elastic part 2 are limited by the first inner annular groove 112 and the second inner annular groove 122 and can not be displaced in the horizontal direction. When the body of rod 13 received inward destructive power, the body of rod 13 can the incurve suffer destruction, and first elastic component 2 can produce certain deformation, weakens the inward destructive power of the body of rod 13, and first elastic component 2 is in compression state between last connecting piece 12 and lower connecting piece 11, guarantees not becoming flexible of the back stock S of the body of rod 13 surrender to protection stock S does not receive the damage.
In some embodiments, the upper surface of the lower connecting member 11 on which the outer ring of the rotation body formed by the rod 13 is located is provided with a first outer annular groove 113, the lower surface of the upper connecting member 12 on which the outer ring of the rotation body formed by the rod 13 is located is provided with a second outer annular groove 123, and two ends of the second elastic member 3 abut against the first outer annular groove 113 and the second outer annular groove 123, respectively. By adopting the technical scheme, the second elastic element 3 is sleeved on the outer ring of the revolving body formed by the rod body 13, and meanwhile, the two ends of the second elastic element 3 are limited by the first outer annular groove 113 and the second outer annular groove 123 and cannot be displaced in the horizontal direction. When the body of rod 13 received outside destructive power, the body of rod 13 can be the outside bending and suffer destruction, and second elastic component 3 can produce certain deformation, weakens the outside destructive power of the body of rod 13, and second elastic component 3 is in compression state between last connecting piece 12 and lower connecting piece 11 simultaneously, guarantees not hard up of the back stock S of the yielding of the body of rod 13 to protection stock S does not receive the damage.
Because the utility model discloses outer anchor, when protecting stock S, can cause the damage of different degrees to the body of rod 13, consequently, in order to continue to use this outer anchor more enough, need can dismantle the change to the body of rod 13. Therefore, the technical solution adopted in this embodiment is: an upper fixing hole 124 is formed in the lower surface of the upper connecting piece 12 between the second inner annular groove 122 and the second outer annular groove 123, an upper threaded hole 125 communicated with the upper fixing hole 124 is formed in the upper surface of the upper connecting piece 12, and a first bolt 126 in threaded connection with the upper end of the rod body 13 is arranged in the upper threaded hole 125; a lower fixing hole 114 is formed on the upper surface of the lower connecting member 11 between the first inner annular groove 112 and the first outer annular groove 113, a lower threaded hole 115 communicated with the lower fixing hole 114 is formed on the lower surface of the lower connecting member 11, and a second bolt 116 in threaded connection with the lower end of the rod body 13 is arranged in the lower threaded hole 115.
By adopting the above technical scheme, through setting up the upper fixing hole 124 and the lower fixing hole 114, the two ends of the rod body 13 can be conveniently inserted into the upper connecting piece 12 and the lower connecting piece 11 respectively, on one hand, the first bolt 126 and the second bolt 116 can be conveniently positioned and locked, and on the other hand, the rod body 13 can be prevented from displacing in the horizontal direction. Through adopting bolt locking between upper connecting piece 12, lower connecting piece 11 and the body of rod 13, can make the body of rod 13 receive external force destruction back, can conveniently dismantle the change to continue normal use.
In some embodiments, the top of the upper connecting member 12 is provided with a locking seat 127, the cross section of the locking seat 127 has a hexagonal shape, and the second insertion hole 121 extends upward and penetrates through the locking seat 127. By adopting the technical scheme, after the top end of the anchor rod S passes through the locking seat 127 through the second insertion hole 121, the locking can be realized through the locking nut, so that the post-anchoring pre-tightening is realized.
As other embodiments, the inner wall of the second insertion hole 121 is provided with an internal thread to be threadedly coupled with the anchor bar S. From this, can make the external screw thread on stock S top insert in the second jack 121 to carry out threaded connection with second jack 121, conveniently use the spanner to fasten through hexagonal locking seat 127, the part that stock S passed the top of locking seat 127 simultaneously can also be carrying out further locking through lock nut.
