Further, the lock further comprises a return spring 11 for returning the sliding block 7, wherein one end of the return spring 11 is installed on the lock shell, and the other end of the return spring is installed on the sliding block 7. The return spring 11 is preferably an extension spring, two the extension springs are respectively installed on two sides of the base 2, one end of the extension spring is connected with the base 2 through an extension spring fixing screw 10, the other end of the extension spring is connected with the sliding block 7 through a screw, in the process that the sliding block 7 moves towards the direction of the positioning block 3, the extension spring always applies a pulling force in the opposite direction to the sliding block 7, the bayonet lock 4 is convenient to stop at the V-shaped opening of the first V-shaped groove, and the bayonet lock 4 is convenient to move towards the advancing section 301 from the retreating section 304.
Furthermore, a compression spring 5 is mounted on the bayonet 4 in a penetrating manner, one end of the compression spring 5 abuts against the cantilever rod 6, and the other end abuts against a boss of the bayonet 4, so that the bayonet 4 presses the bottom of the guide groove. The compression spring 5 always provides acting force pointing to the bottom of the guide groove for the bayonet 4, and the bayonet 4 is always attached to the bottom of the guide groove in the movement process of the bayonet 4 along the guide groove.
Further, the guide groove further includes an initial section 305, and a groove bottom of the initial section 305 is smoothly connected with a groove bottom of the advancing section 301, so that the bayonet 4 enters the advancing section 301 from the initial section 305 and the bayonet 4 enters the initial section 305 from the receding section 304. The initial section 305 and the advancing section 301 together form a pushing section.
Further, the guide chute 15 further has a first horizontal groove and a second horizontal groove and they all extend in the left-right direction, the first horizontal groove, the inclined grooves and the second horizontal groove are connected in sequence, and the first horizontal groove and the included angle between the inclined grooves are obtuse angles, and the second horizontal groove and the included angle between the inclined grooves are obtuse angles. The first horizontal groove, the chute and the second horizontal groove enable the guide chute 15 to be Z-shaped, and in the moving process of the tail plate 9 along with the sliding block 7, the guide chute 15 drives the guide pin 14 to move, so that the pull claw 13 is driven to rotate around the central line of the first hinge shaft on the hinge base 12.
Further, when the guide pin 14 is in the first horizontal groove, the whole pulling claw 13 is located in the lock case, and when the guide pin 14 is in the second horizontal groove, the locking part of the pulling claw 13 is exposed out of the lock case to lock an external object.
Further, the tail plate 9 is mounted on the slider 7 through a connecting plate. The head of the pulling claw 13 is provided with a groove with a corresponding shape according to the shape of the locked external object, the pulling claw 13 is in an upright state at the upper limit position after the lock shell is exposed, and completely enters the shell 1 at the lower limit position after the lock shell is retracted.
The latch 4 is initially positioned when the pull pawl 13 is opened (the locking portion of the pull pawl 13 is in the lock housing), the guide pin 14 is initially positioned in the first horizontal slot, and the latch 4 is positioned in the initial section 305. When the push rod 8 is operated to move the sliding block 7 towards the direction of the positioning block 3, the bayonet 4 moves towards the advancing section 301 along the initial section 305 of the guide groove, the guide sliding groove 15 enters the second horizontal groove from the first horizontal groove through the inclined groove in the moving process of the bayonet 4, the locking part of the pulling claw 13 is exposed from the inside of the lock shell to the outside of the lock shell and locks an external object in the process, and when the bayonet 4 runs to the tail end limit position of the advancing section 301, the bayonet 4 falls into the locking section 302 through the step at the tail end of the advancing section 301; when the push rod 8 is released, the slider 7 returns a distance in the direction away from the positioning block 3 under the action of the return spring 11, and the tail plate 9 also returns a distance, which is equivalent to that the guide pin 14 also returns a distance in the second horizontal groove toward the inclined groove, but because the second horizontal groove is horizontal, the guide pin 14 and the pull claw 13 cannot be driven to rotate in the process that the tail plate 9 returns a distance. When the bayonet 4 moves to the extreme position of the tail end of the locking section 302 along the locking section 302 and falls into the unlocking section 303 through the step at the tail end of the locking section 302, the bayonet 4 can be positioned at the V-shaped opening of the first V-shaped groove and does not move any more, the position of the locking part of the pull claw 13 is limited at the moment, and the pull claw 13 cannot rotate; when the push rod 8 is operated again to move the sliding block 7 towards the direction of the positioning block 3, the bayonet 4 moves along the unlocking section 303 of the guide groove, and when the sliding block moves to the limit position at the tail end of the unlocking section 303, the bayonet 4 falls into the retreating section 304 from the step at the tail end of the unlocking section 303; when the push rod 8 is released again, the slider 7 moves away from the positioning block 3 under the action of the return spring 11, and the bayonet 4 runs along the retreat section 304 of the guide groove and falls into the pushing section through the step at the end of the retreat section 304. If the push segment has a set initial segment 305, it falls into the initial segment 305 until it moves to the beginning position in the initial segment 305. If the initial section 305 is not provided, the bayonet 4 falls into the advancement section 301 and can be positioned at the mouth of the second V-groove and no longer move. The "end" of each segment is referred to as "end" in the moving direction of the bayonet 4, and the end of the bayonet 4 away from the moving direction of the bayonet 4.
In addition, during the movement of the tail plate 9 along with the sliding block 7, the groove wall of the guide sliding groove 15 acts on the guide pin 14, and then the pulling claw 13 is driven to open and close. When the bayonet 4 falls into the unlocking section 303 through the step at the tail end of the locking section 302 of the guide groove, the pull claw 13 is in an upright closed state to lock an external object, and when the pull claw 13 bears external force, the interaction force between the guide pin 14 and the second horizontal groove of the guide chute 15 of the tail plate 9 is in a vertical direction and is in a friction self-locking state; when the bayonet 4 is located at the initial section 305 of the guide groove, the pulling claw 13 is in an open state, and the guide pin 14 is located at the end of the first horizontal groove of the guide sliding groove 15 of the tail plate 9, so that the locking part of the pulling claw 13 does not exceed the top of the housing 1 due to the rotation of the pulling claw 13 caused by the small displacement of the tail plate 9, and the locking device does not interfere with an external object.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
