One side end surface of the push plate 80 is provided with a push rod 802, and when the first push rod 902 and the second push rod 903 move from the lowest end to the uppermost end of the working stroke, the top of the second push rod 903 is gradually close to the push rod 802 of the manual unlocking component.

According to the embodiment of the present application, the front end of the telescopic pin 40 is a spherical end surface 401, the spherical end surface 401 is kept fixed in the tightened state of the telescopic pin 40 to lock the ground wire end 30, and the telescopic pin 40 can move under the pressure at the spherical end surface 401 in the freely telescopic state of the telescopic pin 40 to unlock the ground wire end 30.

As shown in fig. 2, a locking blind hole 404 is formed at the bottom of the telescopic pin 40, and the locking pin 100 can be inserted into the locking blind hole 404 through the locking through hole 105 under the driving of the upward movement of the first push-pull rod 902. When the first push-pull rod 902 moves away from the locking pin 100, the locking pin 100 may withdraw from the locking blind hole 404 under the action of gravity of the locking pin 100 or magnetic force from the first push-pull rod 902, etc., where the locking blind hole 404 is in a clearance fit with the locking pin 100.

The telescopic pin 40 comprises a first limiting step 402, and is installed in the telescopic cavity 102 of the housing 10 to enable axial positioning.

Latching pin 100 includes a second limiting step, latching pin 100 being orthogonal to the axis of telescoping pin 40.

The sleeve includes a third limiting step that cooperates with the first limiting step 402 to limit the telescoping pin 40 within the telescoping chamber 102.

The locking through hole 105 comprises a fourth limiting step, and is matched with the second limiting step, so that the locking pin 100 is limited in the locking through hole 105, and the locking through hole 105 is orthogonal to the axis of the telescopic cavity 102.

As shown in fig. 3, the movable assembly further includes a return spring 50 abutting against the rear end portion of the telescopic pin 40. The return spring 50 can enable the telescopic pin 40 to axially move in the telescopic cavity 102 extended by the shell 10 and can automatically return.

The telescopic pin 40 is arranged in the telescopic cavity 102 of the shell 10, the reset spring 50 is arranged in the rear end spring mounting hole 403, the telescopic pin 40 can axially reciprocate in the telescopic cavity 102 under the action of spring force, and the telescopic pin 40 is integrally arranged in the head cavity of the shell 10 and is fixed in the telescopic cavity 102 through the third limiting step and the rear sealing plate 60.

The automatic unlocking assembly 90 is integrally installed inside the shell 10 and comprises a motor 901, a first push-pull rod 902 and a second push-pull rod 903, the first push-pull rod 902 and the second push-pull rod 903 can axially move under the drive of the motor 901, and the first push-pull rod 902 drives the locking pin 100 to enter and exit the locking blind hole 404.

Referring to fig. 1, in the locked state, the first push-pull rod 902 and the second push-pull rod 903 are driven by the motor 901 and are at the uppermost end of the working stroke thereof, so as to drive the locking pin 100 to be in the jack-up state, i.e. the locking pin 100 passes through the locking through hole 105 and is inserted into the telescopic bottom locking blind hole 404, so that the axial movement of the telescopic pin 40 is limited, at this time, the spherical end surface 401 of the end part of the telescopic pin 40 is inserted into the slot of the ground wire head 30, and when the ground wire head 30 is extracted by external force, the ground wire head 30 cannot be directly pulled out due to the limitation of the axial movement of the telescopic pin 40, thereby realizing the locking function.

As shown in fig. 4, in the authorized unlocking action, the unlocking module 110 sends a signal, and the motor 901 applies a pushing force to the first push-pull rod 902 and the second push-pull rod 903, so as to drive the first push-pull rod 902 to move in a direction of separating from the locking pin 100 until reaching the lowest end of the working stroke, and the locking pin 100 penetrating through the locking through hole 105 is in a falling state under the action of gravity, but also under the action of other forces such as pushing and pulling forces, namely, the locking pin 100 is out of the locking blind hole 404 of the telescopic pin 40, so that the telescopic pin 40 is switched from a locking state to a free telescopic state. At this time, the ground wire head 30 is extracted, the telescopic pin 40 is retracted axially rearward under the force at the spherical end surface 401 thereof, and the ground wire head 30 can be freely pulled out. Thereby realizing the unlocking function. After the earth wire end 30 is pulled out, the telescopic pin 40 is reset to the axial extension to the original position under the action of the reset spring 50. The latch 100 may be switched between a "jack-up state" and a "drop-back state" by gravity or the first push-pull rod 902.

As shown in fig. 5, in the manual unlocking operation, the emergency key rotates the mechanical lock cylinder 70, drives the eccentric shaft 701 to rotate, and drives the push plate 80 to move linearly downwards parallel to the axis of the locking pin 100 because the eccentric shaft 701 and the first limit groove 801 of the push plate 80 form a cam mechanism, and the push rod 802 on the push plate 80 pushes the second push-pull rod 903 of the automatic unlocking assembly 90 to move downwards axially, so that the locking pin 100 falls back from the uppermost end to the lowermost end of the working stroke, and at this time, the locking pin 100 loses the axial limiting effect on the telescopic pin 40 in the telescopic cavity 102. When the external force extracts the ground wire head 30, the telescopic pin 40 can be driven to retract in the axial direction, and the ground wire head 30 can be completely pulled out. Manual unlocking in case of emergency is achieved.

In the locked state, the first push-pull rod 902 and the second push-pull rod 903 are located at the uppermost end of the working stroke, the locking pin 100 is inserted into the bottom locking blind hole 404 of the telescopic pin 40 to lock the telescopic pin 40, in the unlocked state, the first push-pull rod 902 and the second push-pull rod 903 are located at the lowermost end of the working stroke, the locking pin 100 is withdrawn from the bottom locking blind hole 404 of the telescopic pin 40, and the telescopic pin 40 can freely move in the axial direction.

The application uses a double independent unlocking scheme, wherein the manual unlocking and the automatic unlocking are decoupled mutually, the remote control of the locking mechanism and the manual operation under emergency conditions can be realized, the manual unlocking right is higher than the automatic unlocking, and the on-site operation requirement is more met, so that the purpose of realizing multiple control schemes for the ground wire head 30 is realized, in addition, the motor 901 is not directly involved in locking the ground wire head 30, the impact effect on the motor 901 when the ground wire head 30 is locked is avoided in principle, the abnormal movement of the unlocking device caused by the damage of the motor 901 is avoided, and the situation that the locking can not be normally unlocked due to the clamping between the authorized locking pin 100 and the ground wire head 30 caused by assembly processing errors and the like can be avoided.

Meanwhile, the unlocking device with high integration design realizes the anti-prying function and high protection requirement of the manual unlocking component, and greatly ensures the reliability and the management authority requirement. The power consumption and the size of the motor 901, the size of the unlocking device and other elements can be further reduced on the premise of not increasing the complexity of the unlocking device and not reducing the protection level of the whole machine of the shell 10.

According to an aspect of the present application, there is provided a ground wire management locking device including the ground wire locking device as described above, having a first groove 101 on a housing 10 of the ground wire locking device, an axis of the first groove 101 being orthogonal to an axis of a telescopic pin 40.
