Referring to fig. 1-3, embodiments of the present invention provide a locking mechanism that may be applied to any push-pull, pull case waiting lock, such as a case of an electronic device, to enable the case to be quickly locked and unlocked, and to provide a secure lock that is easy to access and maintain. The locking mechanism includes: the lock device comprises a body 10, a first locking piece 20, a second locking piece 30, a handle 40, a connecting rod assembly 50 and a linkage component 60, wherein the first locking piece 20 is movably arranged on the body 10 and is provided with a first locking position and a first unlocking position, the first locking piece 20 stretches out in a first direction and can be switched to the first locking position, and the first locking piece 20 stretches back in a second direction opposite to the first direction and can be switched to the first unlocking position; the second locking piece 30 is connected with the first locking piece 20 through the connecting rod assembly 50 and is provided with a second locking position and a second unlocking position, the second locking piece 30 stretches out to the second direction and can be switched to the second locking position, and the second locking piece 30 withdraws to the first direction and can be switched to the second unlocking position; the handle 40 is rotatably connected to the body 10 and connected to the first locking member 20 through the linkage member 60, and the handle 40 can drive the first locking member 20 to switch positions through the linkage member 60 during rotation, and meanwhile, the first locking member 20 can drive the second locking member 30 to switch positions synchronously through the connecting rod assembly 50.
By adopting the locking mechanism with the structure, the handle 40 can synchronously drive the first locking piece 20 and the second locking piece 30 to move in opposite directions to unlock the object to be locked in the rotating process, as shown in fig. 2, or synchronously drive the first locking piece 20 and the second locking piece 30 to move in opposite directions to lock the object to be locked, as shown in fig. 1, the object to be locked can be locked in two opposite directions, the locking is firm, the operation is simple, the use is convenient, and the purposes of quickly locking and unlocking the object to be locked can be realized.
As shown in fig. 1 and 2, in some embodiments, the body 10 may have a receiving cavity 11 therein, a lock hole 12 may be disposed at a top of the receiving cavity 11, the first locking member 20 may be disposed in the receiving cavity 11 and configured to be able to be extended or retracted from the lock hole 12 to switch positions, and the handle 40 and the second locking member 30 may be disposed at opposite sides of the body 10 so that the handle 40 can be exposed to an outside of an object to be locked when mounted on the object to be locked, and the second locking member 30 can be hidden inside the object to be locked. One end of the link member 60 may extend into the accommodating chamber 11 from the bottom and be connected to the first locking member 20, and the other end extends out of the accommodating chamber 11 and is connected to the handle 40. The link assembly 50 may pass through a wall of the receiving chamber 11 to connect the first locking member 20 and the second locking member 30. Referring to fig. 3, as a preferred embodiment, the first locking member 20 includes a base 21, a locking bolt 22 disposed on the base 21, and a first guide post 23 and a second guide post 24 disposed on the base 21 and respectively near two ends of the locking bolt 22, wherein a first guide hole 13 and a second guide hole 14 are respectively disposed at two ends of the top of the accommodating cavity 11 near the locking hole 12, and the first guide post 23 and the second guide post 24 are respectively connected in the first guide hole 13 and the second guide hole 14. In this way, the first guide post 23 and the second guide post 24 can guide the expansion and contraction direction of the first locking member 20, so as to avoid the offset in the expansion and contraction process of the first locking member 20, which is beneficial to improving the stability of the locking mechanism.
In some embodiments, the handle 40 may have a storage position and a pulling position, when rotated to the storage position, the handle 40 is attached to the body 10, the occupied space is small, when rotated to the pulling position, a pulling space is formed between the handle 40 and the body 10 for the hand to extend into to conveniently pull the handle 40, when the handle 40 forms an angle with the body 10, for example, the handle 40 forms a 90 ° position with the body 10, and when the handle 40 is switched between the storage position and the pulling position, the first locking member 20 can be driven to switch between the first locking position and the first unlocking position synchronously. Thus, when the handle 40 is rotated to the storage position, the object to be locked can be locked, and the handle 40 occupies a small space, which is beneficial to the miniaturization and compact design of the object to be locked. At the same time, unlocking of the object to be locked due to the false touching of the handle 40 can be avoided. When the box 80 needs to be opened, the handle 40 is rotated to a pulling position convenient to pull, at this time, the locking mechanism also realizes unlocking, the box 80 can be opened by pulling the handle 40, and the actions of unlocking and opening the box 80 are consistent and the operation is simple. As a preferred embodiment, a receiving groove 17 for receiving the handle 40 may be provided at the outer side of the body 10, so that the handle 40 may be received in the receiving groove 17 when rotated to the receiving position, thereby making the structure of the locking mechanism more compact and the shape more compact.
In some embodiments, the locking mechanism may further include a reset member (not shown) for providing a reset spring force to the pull handle 40 or the first locking member 20 to enable the pull handle 40 to be reset from the pulled position to the storage position and to drive the first locking member 20 from the first unlocked position to the first locked position, or to reset the first locking member 20 from the first unlocked position to the first locked position and to drive the pull handle 40 to be reset from the pulled position to the storage position. For example, the return member may be one or more return springs, which may be disposed between the bottom end of the first locking member 20 and the bottom wall of the receiving chamber 11, so that the return springs are in a compressed state, thereby having a tendency to eject the first locking member 20 from the locking hole 12. The handle 40 is rotated to drive the first locking member 20 to retract into the accommodating cavity 11 against the elastic force of the spring, and the connecting rod assembly 50 drives the second locking member 30 to switch to the second unlocking position. The handle 40 is released, the first locking piece 20 can stretch out from the lock hole 12 again under the action of the reset elastic force, the second locking piece 30 can be driven to be switched to the second locking position through the connecting rod assembly 50, the handle 40 can be driven to be switched to the storage position through the linkage part 60, and the purposes of self-locking and automatic storage of the handle 40 can be achieved. In the specific implementation process, the reset elastic force which can be provided by the reset piece can be set to be 4 kg, so that the unlocking is avoided due to the false touch, the required control force is moderate during unlocking, and the control comfort is ensured.
As shown in conjunction with fig. 4a, 4b, in some embodiments, the linkage assembly 50 may include: the first connecting rod 51 and the second connecting rod 52, wherein, one end of the first connecting rod 51 is provided with a first bar-shaped hole 53, the first connecting rod 51 is also provided with a second bar-shaped hole 54, the second bar-shaped hole 54 is positioned between two ends of the first connecting rod 51, for example, is positioned in the middle of the first connecting rod 51, and the first bar-shaped hole 53 and the second bar-shaped hole 54 are both arranged along the length direction of the first connecting rod 51. The first locking member 20 is provided with a first pin 25, and the first pin 25 is inserted through the first bar-shaped hole 53 and can slide along the first bar-shaped hole 53. The body 10 is provided with a second pin 15, and the second pin 15 penetrates through the second strip-shaped hole 54 and can slide along the second strip-shaped hole 54; one end of the second link 52 is hinged to the other end of the first link 51, and the other end is hinged to the second locking member 30.
For example, when the first locking member 20 is disposed in the accommodating cavity 11 and the pull handle 40 and the second locking member 30 are disposed on opposite sides of the body 10, the first link 51 and the second link 52 may be disposed on the outer side of the body 10, and the third bar-shaped hole 16 disposed along the extending direction of the first locking member 20 is formed on the side of the accommodating cavity 11, so that the first pin 25 extends from the third bar-shaped hole 16 and passes through the first bar-shaped hole 53, and the second pin 15 is disposed on the outer side of the body 10, so that the second main pin passes through the second bar-shaped hole 54. In this way, when locked, the first locking member 20 extends in the first direction, and drives one end of the first link 51 to move in the first direction, and the other end of the first link 51 moves in the second direction, and drives the second locking member 30 to extend in the second direction through the second link 52, so that the movement direction is exactly opposite when unlocked. The connecting rod assembly 50 is simple in structure, compact in layout, and good in stability, and failure phenomenon is not easy to occur in the use process. In addition, to avoid the space occupied by the link assembly 50, the first link 51 and the second link 52 may be configured in a plate-like structure during the implementation process.
Referring to fig. 5a and 5b, in some embodiments, one end of the linkage member 60 is rotatably connected to the handle 40, and the other end is rotatably connected to the first locking member 20, and during rotation of the handle 40, one end of the linkage member 60 can be driven to move around a rotation center line of the handle 40, and the other end of the linkage member 60 drives the first locking member 20 to switch positions. Specifically, the handle 40 may include a U-shaped handle body 41, two ends of the U-shaped handle body 41 are rotatably connected with the body 10, two ends of the U-shaped handle body 41 are bent toward the same side along a direction perpendicular to a rotation center line, a first bending portion 42 and a second bending portion 43 are formed respectively, a connecting rod 44 is disposed between free ends of the first bending portion 42 and the second bending portion 43, and one end of the linkage member 60 is connected with the connecting rod 44. For example, a first pivot 46 and a second pivot 47 may be provided coaxially at both ends of the U-shaped handle body 41, respectively, the first pivot 46 and the second pivot 47 being pivotally connected to the body 10, i.e., the U-shaped handle body 41 is rotatable relative to the body 10. The first and second bending portions 42 and 43 may be bent to make an angle of 90 ° with both arms of the U-shaped handle body 41. Thus, when the U-shaped handle body 41 is located at the storage position, the first bending portion 42 and the second bending portion 43 are perpendicular to the bottom surface of the storage groove 17 when the U-shaped handle body 41 is attached to the bottom surface of the storage groove 17, and when the U-shaped handle body 41 is switched to the pulling position, that is, when the U-shaped handle body 41 is perpendicular to the bottom surface of the storage groove, the first bending portion 42 and the second bending portion 43 are just parallel to the bottom surface of the storage groove 17, and can drive the connecting rod 44 to synchronously rotate around the rotation center line, one end of the linkage member 60 rotatably connected with the connecting rod 44 also rotates in a circular arc shape around the rotation center line, and the other end of the linkage member 60 can drive the first locking member 20 to move in the first direction or the second direction.

In some embodiments, as shown in fig. 3, a hanging ring 61 may be provided at one end of the linkage member 60, and a hook 45 may be provided on the connecting rod 44, with the hook 45 hanging on the hanging ring 61. During the rotation of the connecting rod 44 around the rotation center line, the linkage member 60 can be pulled by the hook 45, and the hook 45 and the hooking ring 61 can rotate relatively to adjust the angle between the connecting rod 44 and the linkage member 60. Conversely, when the first locking member 20 stretches and contracts, the hook 45 can be pulled by the hooking ring 61 on the linkage member 60 to drive the connecting rod 44 to rotate. The linkage part 60 and the connecting rod 44 are connected with the hook 45 through the hanging ring 61, so that the structure is simple, the installation and the disassembly are convenient, the production difficulty is reduced, and the production efficiency is improved.
In some embodiments, the linkage member 60 may be an isosceles triangle linkage member 60 and the hooking ring 61 may be a bar-shaped hooking ring 61 disposed along the base of the isosceles triangle linkage member 60. For example, a strip-shaped hole can be formed near the bottom edge of the equilateral triangle linkage component 60, a strip-shaped hanging ring 61 with a straight edge can be formed at the bottom edge of the equilateral triangle linkage component 60, the width of the corresponding hanging hook 45 can be similar to the length of the strip-shaped hole, the hanging hook 45 can be a U-shaped groove-shaped hanging hook 45 formed by integrally bending a plate-shaped structure, the hanging hook 45 is hung on the strip-shaped hanging ring 61 during installation, at this time, the straight edge of the strip-shaped hanging ring 61 is clamped in the groove of the U-shaped groove-shaped hanging hook 45 and can rotate in the groove, a structure similar to a rotating shaft is formed, the stress balance is maintained during rotation, and the deviation is not easy to occur. In order to make the linkage member 60 and the connecting rod 44 smoothly rotate, a sleeve 62 may be sleeved on the straight edge, or the straight edge may be cylindrical, so as to avoid jamming in the relative rotation process of the linkage member 60 and the connecting rod 44. With continued reference to fig. 3, the other end of the linkage member 60 may be hinged to the first locking member 20. For example, a bar may be provided at the top end of the isosceles triangle link member 60 (i.e., the other end of the link member) in a direction parallel to the bottom side thereof, and hinged with the first locking member 20 by the bar.
Referring to fig. 6 and 7, an embodiment of the present invention further provides a chassis, which includes: the box 80, the carrier 90 and the locking mechanism 70 as described above, wherein, one end of the box 80 is opened 81, two opposite sides of the opening 81 are respectively provided with a first locking part corresponding to the first locking piece 20 and a second locking part corresponding to the second locking piece 30, the carrier 90 extends into the box 80 from the opening 81 and is slidingly connected with the box 80, the other end of the carrier 90 opposite to the extending end thereof is provided with a box plate 91 for blocking the opening 81, and the locking mechanism 70 is arranged on the box plate 91 for locking the box 80 and the carrier 90.

The chassis with the above structure can be used for carrying electrical components by the carrier 90, and can be used for carrying other articles, for example, the carrier 90 can be made into a drawer shape so as to be convenient for carrying the articles. When the carrier 90 is pushed into the box 80, the locking structure can lock the box 80 and the carrier 90 from two opposite directions, so as to prevent the carrier 90 from sliding out of the box 80, and the locking is firm. When the electrical components on the carrier 90 need to be overhauled or replaced, the handle 40 is rotated and pulled, so that the carrier 90 can be quickly unlocked and pulled out of the box 80, and the operation is simple and convenient, and the user experience is good.
In some embodiments, as shown in fig. 8, one or more third guide posts 31 are disposed on the second locking member 30, and the carrier 90 may be provided with a strip-shaped third guide hole 92 disposed along the extending and retracting direction of the second locking member 30, and the third guide posts 31 are slidably connected in the third guide hole 92.
