Connection cable locking device
A connection cable locking device is configured to selectively hold an elastic hook provided on a connection head of a connection cable, thereby preventing an arbitrary operation of the elastic hook and also preventing the connection head coupled to the connection port from being separated. The connection cable locking device includes a device body provided with a holding operation space and a locking operation space in communication with the holding operation space, a holding member having elasticity and pivotably coupled to the holding operation space so as to hold the elastic hook provided on the connection head of the connection cable, and a locking member slidably coupled to the locking operation space so as to press the holding member.
1 . A connection cable locking device comprising:
a device body provided with a holding operation space and a locking operation space in communication with the holding operation space;
a holding member having elasticity and pivotably coupled to the holding operation space so as to hold an elastic hook provided on a connection head of a connection cable; and
a locking member slidably coupled to the locking operation space so as to press the holding member,
wherein the holding operation space comprises a holding engaging portion, and the holding member comprises:
an engaging coupling block provided with a block engaging portion that is engaged with and coupled to the holding engaging portion;
a support rod that protrudes on the engaging coupling block such that the support rod protrudes toward the elastic hook from the device body; and
a pivot rod which has elasticity and which protrudes on the engaging coupling block such that the pivot rod protrudes toward the elastic hook from the device body.
2 . The connection cable locking device of claim 1 , wherein the device body comprises at least one of:
a cover wing covering the holding member that protrudes from the device body when the holding member is coupled to the holding operation space; or
a rod seating portion on which a portion of the holding member is supported and seated.
3 . The connection cable locking device of claim 1 , wherein a holding groove portion into which the elastic hook is inserted is recessively formed at least one of an end portion of the support rod or an end portion of the pivot rod.
4 . The connection cable locking device of claim 1 , wherein a gap protrusion portion protrudes one of the support rod or the pivot rod, the gap protrusion portion being capable of being in contact with or in close contact with the other of the support rod and the pivot rod when an end portion of the support rod and an end portion of the pivot rod hold the elastic hook.
5 . The connection cable locking device of claim 1 , wherein the locking member comprises a pushing protrusion portion configured to press the pivot rod in response to a slide movement of the locking member.
6 . The connection cable locking device of claim 1 , wherein one of the locking operation space or the locking member comprises a locking hook, and the other of the locking operation space or the locking member comprises:
a locking reciprocating guide forming a movement path of the locking hook;
a release seating portion where the locking hook is engaged with and supported at a first side of the locking reciprocating guide; and
a locking seating portion which is spaced apart from the release seating portion and where the locking hook is engaged with and supported at a second side of the locking reciprocating guide.
7 . The connection cable locking device of claim 1 , further comprising a lock releasing key detachably coupled to the locking member for the slide movement of the locking member.
8 . A connection cable locking device comprising:
a device body provided with a holding operation space and a locking operation space in communication with the holding operation space;
a holding member having elasticity and pivotably coupled to the holding operation space so as to hold an elastic hook provided on a connection head of a connection cable; and
a locking member slidably coupled to the locking operation space so as to press the holding member,
wherein one of the locking operation space or the locking member comprises a locking hook, and the other of the locking operation space or the locking member comprises:
a locking reciprocating guide forming a movement path of the locking hook;
a release seating portion where the locking hook is engaged with and supported at a first side of the locking reciprocating guide; and
a locking seating portion which is spaced apart from the release seating portion and where the locking hook is engaged with and supported at a second side of the locking reciprocating guide.
