DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1-Figure 4As shown, an anchor cable lock with flexible and adjustable anchoring force comprises an anchor pad 2, an anchor cable outer ring 3, an anchor cable inner ring 4, an anchor cable hole 5, a lock clip 1 6 and a lock clip 2 7. The anchor cable body 1 is pre-buried inside the building, and the end of the anchor cable body 1 is exposed from the outside of the building. At this time, the anchor cable can be locked by the anchor cable lock. The anchor cable outer ring 3 is arranged on the surface of the anchor pad 2, and the anchor pad 2 is embedded in the building. The anchor cable inner ring 4 is arranged inside the anchor cable outer ring 3. A plurality of anchor cable holes 5 are opened inside the anchor cable inner ring 4. The shape of the anchor cable hole 5 is truncated. The anchor cable body 1 is passed from one end of the anchor cable hole 5 to the other end, so that each anchor cable body 1 can be connected from different The anchor cable hole 5 is exposed, and the number of anchor cable holes 5 can be adjusted according to the number of anchor cables required. The lock clip 1 6 and the lock clip 2 7 are arranged in pairs, and the lock clip 1 6 and the lock clip 2 7 are embedded in the inside of the anchor cable hole 5. When the anchor cable needs to be locked, the lock clip 1 6 and the lock clip 1 6 are placed on the anchor cable, and then the anchor cable is pulled outward by a special jack. During this period, the positions of the lock clip 1 6 and the lock clip 2 7 located on the special jack remain unchanged, so that the anchor cable moves relative to the lock clip 1 6 and the lock clip 2 7. After the special jack is released, the lock clip 1 6 and the lock clip 2 7 rub the anchor cable, and the lock clip 1 6 and the lock clip 2 7 return to the inside of the anchor cable hole 5 along with the anchor cable.The shapes of the lock clip 1 6 and the lock clip 2 7 are adapted to the interior of the anchor cable hole 5. When the lock clip 1 6 and the lock clip 2 7 are located inside the anchor cable hole 5, it is necessary to prevent the lock clip 1 6 and the lock clip 2 7 from detaching. The lock clip 1 6 and the lock clip 2 7 can be prevented from loosening by a clip anti-loosening structure 8. The side walls of the lock clip 1 6 and the lock clip 2 7 are provided with a clip anti-loosening structure 8. The clip anti-loosening structure 8 includes a plurality of reserved grooves 81, and the reserved grooves 81 are arranged in a circular array on the lock clip 1 6 and the lock clip 2 7. The lock clip 1 6 and the lock clip 2 7 can be tightly plugged inside the reserved groove 81. A fixing strip 82 is placed inside each of the reserved grooves 81. A tilting piece 83 is integrally provided at one end of the fixing strip 82. A friction sheet 84 is provided at the other end of the fixing strip 82. There is a gap between the tilting piece 83 and one end of the fixing strip 82.

The raised piece 83 can prevent the lock clip 16 and the lock clip 2 7 from being discharged from the placement groove 11, thereby ensuring that the lock clip 16 and the lock clip 2 7 lock the anchor cable. The position of the placement groove 11 corresponds to the position of the raised piece 83, and the raised piece 83 is engaged with the placement groove 11 of the anchor cable hole 5. If the lock clip 16 and the lock clip 2 7 tend to loosen and move away from the inside of the anchor cable hole 5, the raised raised piece 83 can press against the edge of the placement groove 11, thereby preventing the raised piece 83 from being separated from the inside of the placement groove 11, and the lock clip 16 and the lock clip 2 7 moving outward will make the raised piece 83 more firmly engaged in the placement groove 11, and the friction between the friction sheet 84 and the inner wall of the anchor cable hole 5 can also reduce the loosening of the lock clip 16 and the lock clip 2 7. ;

[0034] See also Figure 4-Figure 5 As shown, the inner diameter of the placement groove 11 is larger than the inner diameter of the anchor hole 5, and the outer diameter of the lift piece 83 is located between the inner diameter of the reserved groove 81 and the inner diameter of the anchor hole 5, and the friction plate 84 is plugged with the inner wall of the anchor hole 5 to ensure that the lifted lift piece 83 can be located inside the placement groove 11, and when the lift piece 83 is fitted with the fixing strip 82 at a later stage, it can be ensured that the lift piece 83 is detached from the reserved groove 81.

[0035] It should be noted that before the anchor cable is tensioned, the anchor cable is first passed through the anchor, and the anchor cable is clamped by the locking clip 1 6 and the locking clip 2 7, and the anchor cable is connected to the piston rod of the jack, and the hydraulic jack is started to extend the piston rod. As the piston rod extends, the anchor cable is gradually stretched, and the locking clip 1 6 and the locking clip 2 7 are moved to their original positions by the jack, and the anchor cable body 1 moves along the inside of the locking clip 1 6 and the locking clip 2 7. When the preset anchoring force is reached, the hydraulic pump is turned off, and the prestressed steel strand in the anchor cable has reached the predetermined anchoring force, and the stability and bearing capacity of the structure are improved. After the anchor cable is tensioned, the anchor cable needs to be The anchor cable inside the anchor cable hole 5 is prone to loosening, and the anchor cable body 1 can be restricted by the clip anti-loosening structure 8. Since the lock clip 1 6 and the lock clip 2 7 are located inside the anchor cable hole 5, the fixing strip 82 contacts the inner wall of the anchor cable hole 5, and the raised flap 83 enters the inner wall of the placement groove 11, so that the lock clip 1 6 and the lock clip 2 7 are tightly located on the inner wall of the anchor cable hole 5, preventing the lock clip 1 6 and the lock clip 2 7 from loosening from the inside of the anchor cable hole 5, and the friction plate 84 of the fixing strip 82 will also rub against the inside of the anchor cable hole 5, thereby restricting the lock clip 1 6 and the lock clip 2 7 inside the anchor cable hole 5.

[0036] See also Figure 4-Figure 6 As shown, the inner walls of the lock clip 1 6 and the lock clip 2 7 are provided with a connecting long groove 85 at the reserved groove 81, and a fixing nail 86 is provided at one end of the fixing strip 82 and at the tilting piece 83. The fixing nail 86 is inserted into the interior of the connecting long groove 85 in advance, so that the end of the fixing nail 86 can be exposed on the inner wall of the lock clip 1 6 and the lock clip 2 7. One end of the fixing nail 86 is threadedly connected with a nut 811, and the nut 811 is screwed together with the fixing nail 86 to limit the fixing nail 86 from entering too deep into the interior of the lock clip 1 6 and the lock clip 2 7. The fixing nail 86 is located inside the connecting long groove 85. A reserved hole 88 is provided inside the fixing nail 86, and a fixing pin 89 is inserted inside the reserved hole 88. A telescopic spring 810 is provided outside the fixing pin 89 and between the tilting piece 83 and the nut 811. Under the action of the telescopic spring 810, one end of the telescopic spring 810 can expand the tilting piece 83 outward, and the other end of the telescopic spring 810 presses against the nut 811 of the fixing nail 86, thereby ensuring that the fixing nail 86 is always inserted into the lock clip 1 6 and the lock clip 2 7, and when the anchor cable body 1 is located inside the lock clip 1 6 and the lock clip 2 7 inside the anchor cable inner ring 4, no significant loosening will occur.

[0037] See also Figure 5-Figure 6As shown, the fixing pin 89 and the tilting piece 83 move synchronously, the fixing pin 89 is slidably connected with the reserved hole 88 of the fixing pin 86, the fixing pin 86 is slidably connected with the inside of the connecting long groove 85, the end of the fixing pin 86 is located inside the lock clip 1 6 and the lock clip 2 7, the lock clip 1 6 and the lock clip 2 7 are installed inside the anchor cable inner ring 4, so that the fixing pin 86 inside the lock clip 1 6 and the lock clip 2 7 can be inserted into the anchor cable, the inner walls of the lock clip 1 6 and the lock clip 2 7 are both provided with fixing pin 2 87, and the fixing pin 2 87 can also be inserted into the anchor cable.

[0038] It should be noted that the anchor cable body 1 passing through the lock clip 1 6 and the lock clip 2 7 will contact the fixing nail 2 87, and the fixing nail 2 87 can increase the friction of the anchor cable body 1. During this period, since the lock clip 1 6 and the lock clip 2 7 are located inside the anchor cable inner ring 4, under the action of the telescopic spring 810, one end of the telescopic spring 810 presses against the tilting piece 83 to expand outward, thereby preventing the tilted tilting piece 83 from shrinking toward the middle, and one end of the telescopic spring 810 presses against the nut 1 811 to prevent the fixing nail 1 86 from retracting from the lock clip 1 6 or the lock clip 2 7. This structure clamps the anchor cable body 1 inside the lock clip 1 6 and the lock clip 2 7.

[0039] See also Figure 3 , Figure 7 and Figure 8As shown, an adjustment structure 9 is provided inside a reserved groove 81 of the lock clip 1 6 and a reserved groove 81 of the lock clip 2 7. If the anchoring force of the anchor cable needs to be adjusted, the adjustment structure 9 is adjusted to loosen the anchor cable body 1 inside the lock clip 1 6 and the lock clip 2 7. The adjustment structure 9 includes a fixing plate 1 91 and a fixing plate 2 95. The fixing plate 1 91 is sleeved on the outside of the fixing nail 1 86. Pulling the fixing plate 1 91 makes the fixing nail 1 86 move together with the fixing plate 1 91. The fixing plate 2 95 is welded to the inner side of the tilting piece 83.

The screw 93 at the fixing groove 94 and the nut 2 97 can be screwed together by rotating the screw rod 93, so that the end of the screw rod 93 is pulled, and the two connecting strips 92 of the screw rod 93 are moved closer to the middle, and the fixing plate 2 95 of the tilting piece 83 and the fixing plate 1 91 of the nut 1 811 are moved closer to the middle, so that the fixing nail 1 86 is pulled and can be separated from the lock clip 1 6 and the lock clip 2 7, and the tilting piece 83 can be separated from the placement groove 11. At this time, the lock clip 1 6 and the lock clip 2 7 can be loosened, and the tilting piece 83 can be released. The piece 83 and the fixing strip 82 are loosened from the reserved groove 81, and the locking clip 1 6 and the locking clip 2 7 are pulled out from the anchor hole 5 of the anchor inner ring 4. The loosened locking clip 1 6 and the locking clip 2 7 can slide relatively along the anchor body 1, so that when the locking clamp has been along the anchor body 1 for a certain length, the screw 93 is rotated in the opposite direction again, and the length of the screw 93 extending to the tilting piece 83 becomes longer. At this time, the two connecting strips 92 can be unfolded, so that the tilting piece 83 can be unfolded and the fixing nail 1 86 can be inserted into the anchor body 1 under the action of the telescopic spring 810.

[0040] See also Figure 7 and Figure 8 As shown, the size of nut 2 97 is larger than the size of fixing groove 94, and fixing plate 2 95 at the pry plate 83 and fixing plate 1 91 at the nut 1 811 are close to or away from each other, ensuring that nut 2 97 is placed in the fixing groove 94. At this time, the screw rod 93 is pulled to expand or close the two connecting strips 92.

[0041] It should be noted that when the position of the anchor cable and the lock needs to be adjusted, at this time, the nut 2 97 and the fixing groove 94 are rubbed against each other, and the screw 93 is rotated to make the screw 93 rotate relative to the nut 2 97, thereby changing the elongated length of the screw 93, so that the two connecting strips 92 are straightened, so that the fixing plate 1 91 and the fixing plate 2 95 at the connecting strip 92 are close to each other, and the tilted flap 83 is moved closer to the middle, and the fixing nail 1 86 is pulled out from the connecting long groove 85, so that the clip anti-loosening structure 8 can be pulled out from the inside of the anchor cable hole 5, and the anchor cable can be loosened. When the anchoring force of the anchor cable needs to be increased, the lock clip 1 6 and the lock clip 2 7 of the anchor cable can be used to tighten the anchor cable again through a special jack.
