Example 1

Referring to fig. 1 and fig. 2, the present embodiment provides a locking mechanism 100, the locking mechanism 100 includes a first card holder 20 and a second card holder 22 movably connected to each other, a first locking member 24 is disposed on the first card holder 20, a second locking member 26 is disposed on the second card holder 22, the locking mechanism 100 further includes an unlocking operation member 28 connected to the first locking member 24, and the unlocking operation member 28 is operable to disconnect the first locking member 24 from the second locking member 26. Thus, the release operating member 28 is operable to decouple the first cartridge 20 and the second cartridge 22.

Specifically, the first clamping seat 20 and the second clamping seat 22 are pivotally connected through a pin 23, an elastic component, specifically a torsion spring (not shown), is arranged between the first clamping seat 20 and the second clamping seat 22, and the elastic component enables the second clamping seat 22 to be away from the first clamping seat 20, and when an operator overcomes the acting force of the elastic component to enable the second clamping seat 22 to be close to the first clamping seat 20, the first locking piece 24 and the second locking piece 26 can be locked with each other, so that the first clamping seat 20 and the second clamping seat 22 are relatively fixed; when the operator pulls the unlocking operation member 28 to disconnect the first locking member 24 from the second locking member 26, the elastic member is deformed to separate the second card holder 22 from the first card holder 20, so as to disconnect the first card holder 20 from the second card holder 22. Certainly, no elastic component is disposed between the first card holder 20 and the second card holder 22, and at this time, the operating element manually pivots the second card holder 22 to be away from the first card holder 20.

The release operating member 28 is connected to the first locking member 24, and the release operating member 28 pivots the first locking member 24 to be separated from the second locking member 26.

Specifically, referring to fig. 2 and 3, the unlocking manipulating member 28 includes a first side wall 30, a second side wall 32 and a third side wall 34, which are vertically connected in sequence, wherein the first side wall 30 is parallel to the third side wall 34, and the second side wall 32 is perpendicular to the first side wall 30 and the third side wall 34. Preferably, the first, second and third sidewalls 30, 32, 34 are integrally provided. Three side walls of the unlocking operation member 28 form a housing space 36, and the first lock member 24 is receivable in the housing space 36 in the locked state. The unlocking operation member 28 includes three side walls vertically arranged in sequence, and the structure is regular, and those skilled in the art can understand that the unlocking operation member 28 has other shapes, and all the embodiments that are the same as or similar to the present embodiment are covered in the protection scope of the present invention.

The first clamping seat 20 is provided with a first rotating pin 38, and the first rotating pin 38 is pivotally connected with the first clamping seat 20. The unlocking operation member 28 and the first locking member 24 are mounted to the first rotating pin 38, so that the unlocking operation member 28 drives the first rotating pin 38 to pivot relative to the first card holder 20 to drive the first locking member 24 to move.

The first rotating pin 38 includes a flat square shaft portion 40 that is fixedly engaged with the unlocking operation member 28 in the circumferential direction, and an eccentric shaft portion 42 that is engaged with the first locking member 24. The first rotation pin 38 also includes a rotation mating portion 44 that pivotally mates with the first cartridge 20.

Specifically, the first rotating pin 38 extends lengthwise, and includes a flat square shaft portion 40, a rotating mating portion 44, and an eccentric shaft portion 42, which are connected in this order. The flat square shaft portion 40 is connected to the unlocking operation member 28, the rotation mating portion 44 is pivotally mated to the first card holder 20, and the eccentric shaft portion 42 is connected to the first locking member 24. Preferably, the flat square shaft portion 40, the turning fitting portion 44, and the eccentric shaft portion 42 are integrally provided, and thus, the processing is simple and the manufacturing cost is low.

More specifically, the flat square shaft portion 40 is connected to the side wall of the unlocking operation member 28, and particularly, the side wall is connected to the first side wall 30 in a fixed manner in the circumferential direction, that is, there is substantially no relative rotation between the unlocking operation member 28 and the flat square shaft portion 40, and the unlocking operation member 28 can drive the first rotation pin 38 to rotate along with the flat square shaft portion 40.

The rotation coupling portion 44 has a cylindrical shape and is coupled to a cylindrical hole provided in the first cartridge 20, so that the first rotation pin 38 is pivotally coupled to the first cartridge 20, providing for rotation of the unlocking manipulating member 28 and the first rotation pin 38.

The eccentric shaft part 42 comprises an eccentric part 48 with a larger diameter, the first locking part 24 is provided with an accommodating groove 50 matched with the eccentric part 48, the accommodating groove 50 comprises two end parts and a middle part 56 positioned between the two end parts, and when the eccentric part 48 is positioned at the two end parts, the unlocking operation part 28 drives the first locking part 24 to synchronously rotate with the eccentric part; with the eccentric portion 48 in the intermediate portion 56, the eccentric shaft portion 42 pushes the first locking member 24 away from the second locking member 26. For convenience of description, both ends of the receiving groove 50 are defined as a first end 52 and a second end 54, respectively.

When unlocking is required, the unlocking operation member 28 rotates to drive the eccentric shaft portion 42 to rotate, the eccentric portion 48 is sequentially matched with the first end 52, the middle portion 56 and the second end 54 of the accommodating groove 50 in the rotating process of the eccentric shaft portion 42, and the first locking member 24 rotates synchronously with the unlocking operation member 28 when the eccentric portion 48 is matched with the first end 52 of the accommodating groove 50. During the movement of the eccentric portion 48 from the first end 52 toward the middle portion 56, the eccentric portion 48 abuts against the inner wall of the receiving groove 50 to displace the first locking member 24 in the unlocking direction, so that a gap is formed between the first locking member 24 and the second locking member 26, thereby providing a condition for unlocking. Subsequently, the elastic component between the second clamping seat 22 and the first clamping seat 20 causes the second clamping seat 22 to drive the second locking piece 26 to move away from the first locking piece 24, or manually pivots the second clamping seat 22 in a direction away from the first clamping seat 20, so that the second clamping seat 22 drives the second locking piece 26 to move away from the first locking piece 24; meanwhile, the unlocking operation member 28 continues to drive the eccentric shaft portion 42 to rotate, the eccentric portion 48 moves from the middle portion 56 to the second end 54 of the receiving slot 50, and the unlocking operation member 28 drives the first locking member 24 to move away from the second locking member 26, that is, the first locking member 24 and the second locking member 26 move away from each other, so as to unlock the first card holder 20 and the second card holder 22.

In this embodiment, the first locking member 24 and the second locking member 26 are both hook locking members, when the first hook portion 58 of the first locking member 24 is hooked with the second hook portion 60 of the second locking member 26, the first locking member 24 and the second locking member 26 are locked with each other, and when the first hook portion 58 is staggered with the second hook portion 60, the first locking member 24 and the second locking member 26 are not locked again. It will be appreciated by those skilled in the art that other types of locking members are also contemplated and are within the scope of the present invention, and any arrangement similar or identical to the embodiment described herein is contemplated.

Referring to fig. 4, a locking elastic member 62 is disposed between the second locking member 26 and the second clamping seat 22, and the locking elastic member 62 makes the second locking member 26 have a tendency to lock with the first locking member 24. Therefore, when the locking is required again after unlocking, an operator drives the second clamping seat 22 to pivot relative to the first clamping seat 20, and the second locking piece 26 passes over the first locking piece 24 and then is automatically locked with the first locking piece 24 under the action of the locking elastic piece 62, so that the operation is simple.

Referring to fig. 5 and 6, the locking mechanism 100 further includes a safety assembly that prevents the unlocking operation member 28 from being accidentally rotated to unlock the first locking member 24 and the second locking member 26.

The safety assembly comprises a safety block 64 and an elastic member 66, wherein the elastic member 66 applies force to the safety block 64 to enable the safety block 64 to abut against the first locking member 24, so that the first locking member 24 and the second locking member 26 are kept locked. Specifically, a receiving groove is formed on a side of the safety block 64 facing the unlocking operation member 28, an upper end of the elastic member 66 abuts against a lateral protrusion (not shown) of the unlocking operation member 28, and a lower end of the elastic member 66 is received in the receiving groove to apply an urging force to the safety block 64 toward the first locking member 24.

The safety assembly further includes a safety operating member 68 coupled to the safety block 64, the safety operating member 68 moving the safety block 64 away from the first locking member 24 against the force of the resilient member 66. Specifically, the safety block 64 and the safety operation member 68 are respectively disposed on two sides of the unlocking operation member 28, a through long groove (not shown) is disposed on the unlocking operation member 28, the long groove extends along a radial direction of a pivoting direction of the unlocking operation member 28, the safety operation member 68 and the safety block 64 are fixedly connected through a connection member, the connection member extends through the long groove and can slide in the long groove, and therefore the safety operation member 68 and the safety block 64 can slide along an extending direction of the long groove.

More specifically, the safety block 64 is disposed in the accommodating space 36 of the unlocking operation member 28, and the safety operation member 68 is disposed substantially in contact with the outer wall of the unlocking operation member 28, so that space utilization is very reasonable. The connecting assembly includes a connecting seat 70 provided on a side surface of the safety operating member 68 facing the unlocking operating member 28, and a connecting pin 72 detachably connected to the connecting seat 70. The connecting base 70 includes a base 74 having a relatively large area, and a pedestal 76 having a relatively small area and disposed on the base 74. The base 74 is slidable within the elongated slot and the pedestal 76 is adapted to be fixedly attached to the safety block 64. The pedestal 76 is provided with a hole capable of being fixedly connected with the connecting pin 72, in this embodiment, the connecting pin 72 is a connecting screw, and the safety block 64 is provided with a through hole 73 through which the connecting pin 72 can pass. Therefore, the stud part of the connecting pin 72 passes through the through hole 73 on the safety block 64 and then is fixedly connected with the hole of the pedestal 76, the nut part of the connecting pin 72 stays on one side of the safety block 64 far away from the safety operation part 68, and the connecting pin 72 is matched with the connecting seat 70 to relatively fix the safety block 64 and the safety operation part 68, so that the movement of the safety operation part 68 can drive the movement of the safety block 64.

To facilitate operation of the safety operation member 68, the safety operation member 68 is disposed to surround the outer surface of the unlocking operation member 28. One end of the safety operation member 68 is provided with a wrench portion 67, and the wrench portion 67 extends in a direction away from the outer surface of the unlocking operation member 28. Preferably, the lower surface of the wrench portion 67 is at a right angle or an acute angle to the outer surface of the unlocking manipulating member 28.

Thus, when unlocking is required, the operator operates the safety operation element 68 first and then operates the unlock operation element 28, thereby preventing erroneous operation. Specifically, an operator can use a hand to abut against the lower surface of the wrench part 67 close to the first card holder 20 and lift the wrench part 67 in a direction away from the first card holder 20, so as to overcome the acting force of the elastic part 66 to drive the safety block 64 to move in a direction away from the first card holder 20, the safety block 64 leaves the first locking part 24, and the safety block 64 no longer applies force to the first locking part 24 and no longer keeps the first locking part 24 locked with the second locking part 26; subsequently, the operator can drive the safety operation member 68 and the unlocking operation member 28 to pivot relative to the first card holder 20 together, and the unlocking operation member 28 drives the first locking member 24 and the second locking member 26 to be staggered in the pivoting process relative to the first card holder 20, so as to realize unlocking, which is not described in detail.

With continued reference to fig. 5 and 6, the first card socket 20 includes a first card slot 81 and a second card slot 82 which are arranged at an interval, the safety operation element 68 has a first state and a second state relative to the first card socket 20, and in the first state, the safety operation element 68 is partially clamped into the first card slot 81; in the second state, the safety operator 68 is partially snapped into the second card slot 82. Specifically, one end of the safety operation element 68, that is, the end far away from the wrench portion 67, is provided with an insertion portion 69, and in the first state, the insertion portion 69 is inserted into the first slot 81; in the second state, the plug portion 69 is inserted into the second card slot 82. The insertion portion 69 is parallel to the outer side surface of the unlocking manipulating member 28 and is operatively engaged with the first engaging groove 81 or the second engaging groove 82. The structure design is reasonable, and the use is convenient. In this embodiment, the number of the insertion parts 69 is two, and the number of the first locking grooves 81 and the number of the second locking grooves 82 are two, and the first locking grooves and the second locking grooves are arranged at intervals, so that the structure is symmetrical, the stress is uniform, and the operation is stable.

Specifically, when the first locking member 24 and the second locking member 26 are locked with respect to each other, the safety operation member 68 is located in the first state with respect to the first card seat 20, and at this time, the insertion portion 69 is inserted into the first card slot 81; only after the safety operation member 68 is pulled by an operator in a direction away from the first card holder 20, so that the safety operation member 68 is separated from the first card holder 20, and the safety operation member 68 drives the safety block 64 to be separated from the first locking member 24, the first locking member 24 and the second locking member 26 are driven to be separated and unlocked by the unlocking operation member 28, so as to prevent misoperation.

After the first locking member 24 and the second locking member 26 are unlocked, the safety operation member 68 is located in the second state relative to the first card holder 20, and the insertion portion 69 is pulled into the second card slot 82, so that the positions of the unlocking operation member 28 and the first locking member 24 are relatively fixed, and accurate re-locking of the first locking member 24 and the second locking member 26 is ensured.

The first catching grooves 81 and the second catching grooves 82 are circumferentially spaced in the pivoting direction of the unlocking operation member 28. Thereby facilitating switching of the safety operating member 68 between the first state and the second state.

The safety operating member 68 is fixed relative to the unlocking operating member 28 in the pivoting direction of the unlocking operating member 28, that is, the safety operating member 68 is fixed relative to the unlocking operating member 28 so as to be pivotable in synchronization when the unlocking operating member 28 is pivoted to be unlocked. As can be seen from the above description, the safety operation member 68 and the unlocking operation member 28 can be relatively moved in the radial direction of the first rotation pin 38, so that the safety operation member 68 moves the safety block 64 away from the first locking member 24; since the safety operation element 68 and the unlocking operation element 28 are circumferentially fixed relatively, after the safety block 64 moves, the safety operation element 68 and the unlocking operation element 28 pivot relative to the first card holder 20 together, during the pivoting process, the safety operation element 68 disengages from the first card slot 81 and moves towards the second card slot 82, and after unlocking, the safety operation element 68 can be inserted into and matched with the second card slot 82, so that the first locking element 24 and the second locking element 26 can be accurately locked again.

It should be noted that during the unlocking process, the operator pivots the safety operating member 68 and the unlocking operating member 28 in a direction away from the first card seat 20, so that the safety operating member 68 may pass over the second card slot 82. Referring back to fig. 3, for this purpose, a reset piece 78 is disposed between the safety operation piece 68 and the first card socket 20, and the safety operation piece 68 overcomes the acting force of the reset piece 78 and rotates along the first card slot 81 toward the second card slot 82; after the first locking member 24 is separated from the second locking member 26, even if the safety operation member 68 passes over the second locking groove 82, the reset member 78 can make the safety operation member 68 be locked in the second locking groove 82, thereby ensuring accurate relocking.

Referring to fig. 6 to 10, the operation of the locking mechanism 100 of the present embodiment will be described.

As shown in fig. 6, when the first cartridge 20 and the second cartridge 22 are in the locked state, the first locking element 24 and the second locking element 26 (shown in fig. 2) are locked with each other, and the safety block 64 abuts against the first locking element 24 under the action of the elastic element 66, so that the first locking element 24 and the second locking element 26 are locked more reliably. Meanwhile, the insertion part 69 of the safety operation element 68 is inserted and matched with the first clamping groove 81 of the first clamping seat 20, and at the moment, even if an operator mistakenly pulls the safety operation element 68 and/or the unlocking operation element 28 to enable the safety operation element to pivot relative to the first clamping seat 20, accidental unlocking cannot be generated, and accidents are prevented.

When the operator needs to unlock, a part of the fingers of one hand, for example, the index finger, can abut against the lower surface of the trigger portion 67 of the safety operation member 68, while the other part of the fingers of the one hand, for example, the thumb, abuts against the side of the unlocking operation member 28 away from the safety operation member 68; subsequently, the index finger of the operating member lifts the safety operating member 68 against the action force of the elastic member 66, that is, the safety operating member 68 is moved in the radial direction of the first rotating pin 38 away from the first card holder 20, so that the insertion portion 69 of the safety operating member 68 is separated from the first card slot 81, in the process, the safety operating member 68 drives the safety block 64 to lift, and the safety block 64 is staggered from the first locking member 24, at this time, a condition is created for unlocking.

Subsequently, referring to fig. 7 to 8, when the operator drives the safety operation member 68 and the unlocking operation member 28 to pivot together relative to the first card holder 20, and the unlocking operation member 28 drives the first rotating pin 38 (shown in fig. 3) to pivot relative to the first card holder 20, the eccentric portion 48 of the first rotating pin 38 abuts against the inner wall of the receiving groove 50 of the first locking member 24, so that the first locking member 24 is displaced along the unlocking direction, the first locking member 24 is staggered from the second locking member 26, and when the position between the first locking member 24 and the second locking member 26 is farthest, the insertion portion 69 of the safety operation member 68 is opposite to the second card slot 82. At this time, if the operator does not stop, and continues to pivot the safety operation member 68 and the unlocking operation member 28, the insertion part 69 is not inserted into the second card slot 82; if the operator releases the safety operation member 68 and the unlocking operation member 28, the plug portion 69 is automatically inserted into the second card slot 82. During this process, the first locking member 24 is displaced in the unlocking direction and partially out of alignment with the second locking member 26 as the unlocking operation member 28 and the safety operation member 68 are pivoted through a small angle.

Referring to fig. 9 and 10, subsequently, the operator further drives the safety operation element 68 and the unlocking operation element 28 to pivot relative to the first card holder 20 together (if the insertion portion 69 is inserted into the second card slot 82 in the previous step, an action of pulling out the safety operation element 68 is added, which is not described in detail), the pivoting of the unlocking operation element 28 drives the first locking element 24 to pivot therewith, so that the first locking element 24 is further staggered from the second locking element 26, at this time, the second card holder 22 automatically moves away from the first card holder 20 under the action of the elastic component, and the operator can also manually pull the second card holder 22 away from the first card holder 20; at this time, the operator can release the safety operation member 68 and the unlocking operation member 28, the safety operation member 68 and the unlocking operation member 28 are reversely pivoted by the reset member 78, and when the insertion portion 69 of the safety operation member 68 is aligned with the second notch 82, the safety operation member 68 is inserted into the second notch 82 by the elastic member 66. So far, the unlocking is completed, the insertion part 69 of the safety operating part 68 is inserted into and matched with the second clamping groove 82, and the positions of the unlocking operating part 28 and the first locking part 24 linked with the unlocking operating part 28 are fixed, so that the first locking part 24 and the second locking part 26 can be accurately locked again.

When the locking is required again, referring to fig. 10 and 6, an operator pivots the second card holder 22 towards the first card holder 20 to lock the second locking member 26 with the first locking member 24, and then, the operator pulls out the safety operation member 68 from the second card slot 82 and drives the safety operation member 68 and the unlocking operation member 28 to pivot reversely until the insertion portion 69 of the safety operation member 68 is opposite to the first card slot 81, and after the insertion portion 69 is opposite to the first card slot 81, the operator releases the safety operation member 68, the safety operation member 68 moves towards the first card slot 81 under the action of the elastic member 66, the insertion portion 69 is inserted into the first card slot 81, and meanwhile, the safety block 64 abuts against the first locking member 24 to prevent mistaken unlocking.

In summary, the safety operating member 68 slides relative to the unlocking operating member 28 and then rotates with the unlocking operating member 28, and the two moving directions of the safety operating member 68 are different, so that the incorrect unlocking is prevented very reliably.
