In order to solve the problem that ground wire stake lock application scope is little and performance is poor among the prior art, this application provides a ground wire stake lock.

As shown in fig. 1 to 10, the ground wire pile lock in the present application includes a ground wire, a fixing member 13, a fixing lock 30, and a limiting member 40. The ground wire is provided with a ground wire head 20, and the ground wire head 20 is arranged on the mounting hole 11 of the pile body 12 of the pile body assembly 10 in a penetrating way; the fixing pieces 13 are arranged on two sides of the pile body assembly 10; the fixing lock 30 is movably arranged on the pile body assembly 10 through a fixing piece 13; the limiting member 40 is connected with the fixing lock 30, the limiting member 40 has a limiting position and an avoiding position, the limiting member 40 can be locked at the limiting position by the fixing lock 30, and at least a part of the limiting member 40 abuts against the ground wire head 20 to limit the ground wire head 20 on the pile assembly 10; when the fixed lock 30 is unlocked by using a key, the fixed lock 30 is switched from the locked state to the unlocked state, the fixed lock 30 releases the locking of the limiting member 40, the limiting member 40 can be switched from the limiting position to the avoiding position, the limiting of the ground wire head 20 is released, and the ground wire head 20 can be taken down from the pile assembly 10.

To sum up, the fixing lock 30 is movably arranged on the pile body assembly 10 through the fixing piece 13, so that the fixing lock 30 can meet the installation requirement of the existing ground wire pile (pile body assembly), and the problems of poor adaptability and small application range of the existing fixing lock 30 are solved; the ground wire head 20 can be installed after penetrating through the two ends of the pile body assembly 10 respectively, and at the moment, the limiting part 40 can be abutted against the ground wire head nut 21 or the ground wire head screw 22 of the ground wire head 20 to limit the ground wire, so that the ground wire is stably locked on the pile body assembly 10, the limitation on the insertion direction of the ground wire is reduced, and the installation flexibility of the ground wire pile lock is improved.

In the present application, after the ground wire head screw 22 of the ground wire head 20 passes through the mounting hole 11 from one side of the mounting hole 11, the ground wire head nut 21 is screwed with the ground wire head screw 22 on the other side of the mounting hole 11, so as to secure the ground wire head 20 to the pile assembly 10.

Specifically, the ground wire head 20 can pass through the mounting hole 11 from both sides of the pile assembly 10 so that the ground wire head nut 21 of the ground wire head 20 or the ground wire head screw 22 of the ground wire head 20 abuts against the limiting member 40, so that the ground wire head 20 cannot be removed from the pile assembly 10.

In an embodiment of the present application, when the limiting member 40 is installed, as shown in fig. 3, at this time, the limiting member 40 abuts against the ground wire head nut 21 of the ground wire head 20, so that the ground wire head nut 21 cannot be removed from the ground wire head screw 22 of the ground wire head 20, and at this time, the ground wire head nut 21 cannot be unscrewed from the ground wire head screw 22, so that the ground wire head screw 22 cannot be removed from the pile assembly 10, and thus, the limiting locking of the ground wire head 20 is achieved; as shown in fig. 9 and 10, at this time, the stopper 40 abuts against the ground bolt 22 of the ground bolt 20 to disable the removal of the ground bolt 22 from the pile assembly 10, and at this time, although the ground bolt 21 can be removed from the ground bolt 22, the stopper 40 abuts against the ground bolt 22 to disable the removal of the ground bolt 22 from the mounting hole 11, thereby achieving the stopper locking of the ground bolt 20.

In one embodiment of the present application, the wire cap screw 22 has a threaded section, a boss and a wire connection end, and the stop 40 abuts the boss.

Through the arrangement, when the installation position of the ground wire in one installation direction is limited, the installation direction of the ground wire can be adjusted to enable the ground wire to penetrate through the pile body assembly 10, so that the installation of the ground wire pile lock is completed; alternatively, the installation position of the fixing lock is adjusted while the position of the stopper 40 follows the position of the fixing lock 30.

As shown in fig. 1 and fig. 2, the pivoting end 421 of the limiting member 40 is pivotally connected to the fixing lock 30, and an end of the limiting member 40 away from the pivoting end 421 protrudes to form a stopping tongue 43, and the stopping tongue 43 can cooperate with the ground wire head 20 to realize the stopping. With this arrangement, when the lock 30 is switched from the locked state to the unlocked state, the stopper 40 can rotate relative to the lock 30, and thus can be switched between the stopper position and the escape position.

As shown in fig. 2, the limiting member 40 includes a main body 41, a pivot portion 42, and a stopping tongue 43. The pivoting part 42 is arranged on the main body part 41 and has a pivoting end 421, and the pivoting end 421 is pivotally connected with the fixing lock 30; the latch 43 is connected to the main body 41, and the latch 43 and the pivot portion 42 are respectively located on two sides of the main body 41. With this arrangement, when the limiting member 40 is mounted, the pivoting portion 42 can be connected to the fixing lock 30 to rotate relative to the fixing lock, and the stop tongue 43 can limit the ground lead 20.

As shown in fig. 2, the latch 43 and the pivot portion 42 extend in opposite directions. By such an arrangement, it can be ensured that the stopper 40 is more flexibly mounted.

As shown in fig. 2, the catch 43 is perpendicular to the body portion 41. Through the arrangement, when the limiting member 40 is located at the limiting position, the stop tongue 43 can be ensured to be more attached to the ground wire head nut 21 or the ground wire head screw 22, so that the limiting effect of the limiting member 40 on the ground wire head 20 is ensured.

In one embodiment of the present application, the width of the catch 43 tapers away from the body portion 41. By this arrangement, the space occupied by the latch 43 can be effectively reduced.

As shown in fig. 2, the fixing lock 30 has a mounting groove 31, the pivoting end 421 extends into the mounting groove 31, and a portion of the pivoting end 421 extending into the mounting groove 31 has a connecting hole 422, and the ground pile lock further includes a cylindrical pin 50, wherein the cylindrical pin 50 is located inside the fixing lock 30 and passes through the connecting hole 422, so that the limiting member 40 can rotate around the cylindrical pin 50. By arranging the mounting groove 31, the movement of the pivoting end 421 of the limiting member 40 can be limited, so that the pivoting end 421 can move according to the set track of the mounting groove 31 in the process of switching the limiting member 40 between the limiting position and the avoiding position, and the blocking tongue 43 can be aligned to the ground wire end nut 21 or the ground wire end screw 22.

As shown in fig. 2, the pivoting end 421 further has a locking hole 423.

As shown in fig. 3 to 5, when the fixing lock 30 is in the locked state, at least a portion of the locking pin 35 can extend into the locking hole 423 to lock the limiting member 40. At this time, after at least a portion of the locking pin 35 is inserted into the locking hole 423, the position-limiting member 40 cannot rotate with respect to the fixed lock 30, and thus is maintained at the position-limiting position.

As shown in fig. 6 to 8, when the fixing lock 30 is in the unlocked state, the portion of the latching pin 35 protruding into the locking hole 423 can exit the locking hole 423. At this time, the locking pin 35 no longer locks the limiting member 40, so that the limiting member 40 can rotate relative to the fixed lock 30, and can be switched from the limiting position to the avoiding position.

As shown in fig. 2, the fixed lock 30 includes a lock case 32, and a lock cylinder 33, a rotating shaft 34, a locking pin 35 and a first reset piece 36 respectively disposed inside the lock case 32, wherein the lock cylinder 33 can drive the rotating shaft 34 to rotate so that the rotating shaft 34 can adjust the position of the locking pin 35, so that the fixed lock 30 can be switched between an unlocking state and a locking state, and two ends of the first reset piece 36 respectively abut against the locking pin 35 and the lock case 32 to provide a reset force for the locking pin 35 to enter the locking hole 423 of the limiting piece 40. When the key is used to unlock the fixed lock 30, the key rotates the key cylinder 33, so that the key cylinder 33 rotates the rotary shaft 34. When the rotating shaft 34 drives the locking pin 35 to exit from the locking hole 423, the fixed lock 30 is switched from the locking state to the unlocking state, and the limiting member can be freely switched between the limiting position and the avoiding position; if the key is rotated reversely, so that the lock cylinder 33 drives the rotating shaft 34 to move reversely, the locking pin 35 will extend into the locking hole 423 under the action of the first resetting piece 36, so that the fixed lock 30 is switched from the unlocking state to the locking state, and the limiting piece is locked at the limiting position.

As shown in fig. 5, the locking pin 35 has an unlocking recess 351, the rotating shaft 34 has an unlocking protrusion 341, when the unlocking protrusion 341 enters the unlocking recess 351 and presses a side wall of the unlocking recess 351, the first restoring member 36 is compressed, the fixed lock 30 is switched from the locked state to the unlocked state, and when the unlocking protrusion 341 exits the unlocking recess 351, the first restoring member 36 drives the locking pin 35 to move, and the fixed lock 30 is switched from the unlocked state to the locked state. With this arrangement, when the fixed lock 30 is switched from the locked state to the unlocked state, the lock cylinder 33 drives the rotating shaft 34 to rotate, and the unlocking protrusion 341 of the rotating shaft 34 can press the side wall of the unlocking recess 351, so that the locking pin 35 can exit from the locking hole 423, and the lock of the limiting member 40 is released. During the process of switching the fixed lock 30 from the unlocked state to the locked state, the unlocking protrusion 341 can exit the unlocking recess 351 along with the rotation of the rotating shaft 34, and the locking pin 35 can enter the locking hole 423 and lock the limiting member 40 under the action of the first restoring member 36.

In the present application, the fixing lock 30 further includes a raw ear 37, a dust cover 38, and a spring piece 39. The lug 37 is arranged on the lock shell 32; the dust cover 38 is arranged at the key insertion opening of the lock shell 32, and one end of the dust cover 38 is connected with the lug 37 so that the dust cover 38 can rotate around the lug 37; the elastic sheet 39 is arranged between the dust cover 38 and the lock case 32, one end of the elastic sheet 39 is fixedly connected with the lock case 32, and the other end of the elastic sheet 39 is abutted against the dust cover 38. The key insertion hole of the fixed lock 30 can be protected by the dust cover 38, so that dust can be prevented from entering the key insertion hole, the service performance of the fixed lock 30 is ensured, and the service life of the fixed lock 30 is prolonged. Further, since the elastic piece 39 is further provided, an urging force can be applied to the dust cap 38 by the action of the deformation of the elastic piece 39 itself, and the dust cap 38 can be securely attached to the lock case 32. In addition, when the dust cover 38 is opened, the elastic piece 39 itself deforms, so that an acting force can be applied to the dust cover 38, and the dust cover 38 is ensured to be kept in an open state.

Optionally, the ground wire pile lock further includes a second reset member 51, one end of the second reset member 51 abuts against the fixed lock 30, and the other end of the second reset member 51 abuts against the limiting member 40, so as to provide a reset force for the limiting member 40 to switch from the limiting position to the avoiding position. With this arrangement, when the limiting member 40 is switched to the avoidance position, the limiting member 40 can be returned to the avoidance position by the second returning member 51 without the action of other external force.
