In the present embodiment, the lock cylinder member 152 is hollow inside to form a torsion spring seat for the reset torsion spring to be disposed, and the side wall thereof is further formed with a torsion spring notch 158 for one end of the reset torsion spring to pass through and then be fitted onto the second locking member 140, so as to achieve the purpose that the unlocking member 150 keeps locked with respect to the second locking member 140.

As shown in fig. 9, a through hole 141 is formed in the second locking element 140, the lock cylinder 152 passes through the through hole 141 and then fits into the second locking element 140, and the operating element 151 is located outside the second locking element 140.

The through hole 141 is provided with a first channel 144 and a second channel 142 corresponding to the limit protrusion 153 and the locking protrusion 154, respectively, to allow the limit protrusion 153 and the locking protrusion 154 to pass through when the lock cylinder member 152 passes through the through hole 141.

One side of the first channel 144 is provided with a stop portion 147, the other side is provided with a rotating portion 146, and the rotating portion 146 is provided with a stop portion 145. A step 143 is further provided at one side of the second channel 142.

The second locking element 140 is further provided with a third limiting element 104 matched with the second positioning element 128 on the bottom plate element 160, and the third limiting element 104 is a limiting hole to limit rotation.

As shown in fig. 6 and 9, the bottom plate 160 and the second locking element 140 are respectively provided with a locking protrusion 129 and a locking position 149, and the locking protrusion 129 cooperates with the locking position 149 to detachably engage the bottom plate 160 and the second locking element 140 in a mutually locked manner. Of course, it is also possible to connect the bottom plate member 160 and the second locking member 140 by using screws.

As shown in fig. 10, when the unlocking member 150 is engaged with the second locking member 140, the limiting projection 153 is limited by the stopper 147 in a rotational direction, which is referred to as a locking direction, i.e., a direction B shown in the drawing; in the opposite rotational direction, the stopper protrusion 153 is rotatable along the rotary portion 146, which is referred to as an unlocking rotational direction, i.e., a direction a shown in the drawing.

As shown in fig. 11, in the locked state, the second stepped portion 155 is locked by the first stepped portion 134 to lock the multi-function lock in the up-down direction. The upper surface of the operating element 151 is formed with a rotating shaft 105 and an operating part 106, wherein the operating part 106 has a smooth surface and the rotating shaft 105 is formed in a circular shape.

Therefore, the unlocking operation of the unlocking member 150 is to apply a force to rotate the unlocking member 150, and the second locking member 123 is lifted up with respect to the base 110 while maintaining the rotational unlocking, to achieve the unlocking of both.

After the unlocking member 150 is engaged with the second locking member 140, the inner wall of the limiting protrusion 153 abuts against the blocking portion 145, so that the unlocking member 150 and the second locking member 140 are kept engaged and cannot be disengaged.

In the present embodiment, the limiting protrusion 153 is longer than the locking protrusion 154, and correspondingly, the second channel 142 of the second locking element 140 is also longer than the first channel 144; when it is required to separate the unlocking member 150 from the second locking member 140, the unlocking member 150 may be rotated in the unlocking direction such that the stopper protrusion 153 is fitted at the second passage 142 and the locking protrusion 154 is fitted at the first passage 144, and thus the stopper protrusion 153 passes through the second passage 142 and the locking protrusion 154 passes through the first passage 144, and the unlocking member 150 is separated from the second locking member 140.

In the locked state, the second step 155 engages the first step 134 to engage the unlocking member 150 with the first locking member 130 to form a locking connection. When the lock is to be unlocked, the unlocking member 150 is rotated to separate the second step portion 155 from the first step portion 134, so that the lock body 120 is separated from the base 110. Then, the second locking member 123 is separated from the base 110, so as to achieve the purpose of separating the locking body 120 from the base 110.

Wherein the plane of rotation of the unlocking member 150 is substantially perpendicular to the direction of locking or unlocking displacement of the second locking member 123 and the base 110. As shown in fig. 2, the separating direction of the base 110 and the second locking part 123 is an unlocking displacement direction, and the unlocking rotation direction of the unlocking part 150 is formed by rotating the unlocking part 150 along the surface of the second locking part 123, which is a surface substantially parallel to the first abutting surface 101. Therefore, the two are disposed perpendicular to each other.

Of course, the rotation plane of the unlocking member 150 is not necessarily parallel or substantially parallel to the first abutting surface 101, and when the front surface of the second locking member 123 is disposed obliquely, it may also be disposed at an angle to the first abutting surface 101, and although it is not perpendicular to the unlocking displacement direction, the operation effect is similar, and the same effect can be achieved.

In this embodiment, during unlocking, the unlocking member 150 is fitted into the stopper cavity 126 and is stopped by the first stopper post 125 provided on the bottom plate member 160, so that the unlocking member 150 cannot be rotated to a position where it can be disengaged from the second locking member 140.

The unlocking member 150 can be disengaged from the second locking member 140 only by rotating the unlocking member 150 by a predetermined angle, in this embodiment, 90 °, in the unlocking rotational direction after separating the whole body formed by the engagement of the unlocking member 150 and the second locking member 140 from the bottom plate member 160.

In this embodiment, after the unlocking member 150 is rotated along the direction a, the second locking member 123 is displaced from the base 110 to separate the two, so that the whole unlocking operation can be completed; due to the effect of the reset torsion spring, the unlocking piece 150 can reversely rotate along the direction B to return to the original position, when the second locking piece 123 needs to be matched with the base 110 to lock the two, the second locking piece 123 can be directly displaced towards the base 110, the unlocking piece 150 can automatically rotate along the direction a under the matching effect of the first guide surface 131 and the second guide surface 157, and therefore the first step portion 134 and the second step portion 155 are matched to lock.
