Description

Technical Field

[0001] This invention relates to lock structures, and more particularly to a lock structure that can change the direction of the locking mechanism. Background Technology

[0002] In existing technologies, various lock structures are widely used in door locks, security boxes, mechanical devices, and other fields. They prevent unauthorized opening through the cooperation of the bolt or latch and the lock seat. However, most locks have a fixed locking direction, which users cannot adjust according to actual installation needs. Therefore, when facing different installation locations (such as left-opening doors and right-opening doors), it is necessary to purchase locks with the corresponding direction, increasing inconvenience in use.

[0003] Furthermore, while existing technologies have proposed adjustable locking mechanisms to adapt to different door opening directions, these are often complex in structure, difficult to assemble, or require specialized tools for adjustment, reducing their practicality and widespread adoption. In addition, changing the locking direction can lead to a decrease in structural stability or security in some lock designs, thus requiring further improvement.

[0004] Therefore, the goal of this applicant's research is to provide a lock structure that is simple in structure, easy to operate, and can change the direction of the locking mechanism as needed to improve application flexibility and ease of use. Summary of the Invention

[0005] One objective of this invention is to provide a lock structure with a changeable locking direction, which has the advantages of simple structure, easy operation, and the ability to change the locking direction as needed, thereby improving application flexibility and ease of use.

[0006] To achieve the above objectives, the present invention provides a lock structure with a changeable locking direction, comprising a housing, a lock cylinder assembly, a knob, a control plate, and a bolt. The housing includes a housing base and a panel attached to the housing base. The housing base has a lock cylinder, which has a rotation space and a limiting surface located on one side of the rotation space formed on its end face away from the panel. The lock cylinder assembly includes a lock cylinder and a rotating shaft. The lock cylinder is rotatably housed in the lock cylinder, and the rotating shaft passes through the lock cylinder, with a locking portion and a connecting portion provided at its protruding end from the lock cylinder. The knob is attached to the panel and detachably connected to the lock cylinder. The control plate is fixed to the locking portion of the rotating shaft and rotates with the rotating shaft, including a first stop and a second stop spaced apart and angled. The bolt is detachably fixed to the connecting portion and rotates with the rotating shaft. When the control plate is mounted on the locking part of the rotating shaft with its first stop abutting against the limiting surface, the second stop can rotate in the rotation space in the first direction to abut against the limiting surface; when the control plate is mounted on the locking part of the rotating shaft with its second stop abutting against the limiting surface, the first stop can rotate in the rotation space in the second direction to abut against the limiting surface.

[0007] In one embodiment of the present invention, the lock structure further includes an operation group, the panel is provided with a plurality of slots, the operation group is disposed inside the panel and partially exposed outside the slots.

[0008] In one embodiment of the present invention, the knob includes a knob post and a wrench connected to the knob post. The knob post has a lock hole and the knob post is detachably connected to the lock cylinder.

[0009] In one embodiment of the present invention, the latching part is a rectangular block, and the control piece is provided with a rectangular hole. The control piece is positioned on the rotating shaft by engaging the latching part through the rectangular hole.

[0010] In one embodiment of the present invention, the first stop and the second stop are a plane.

[0011] In one embodiment of the present invention, the control piece includes a rotating portion located between the first stop portion and the second stop portion.

[0012] In one embodiment of the present invention, the rotating part is an arc surface.

[0013] In one embodiment of the present invention, the control piece is a rhomboid piece.

[0014] In one embodiment of the present invention, the latch includes a fixed section and a locking section, the locking section being connected to the fixed section and protruding from one side of the housing.

[0015] In one embodiment of the present invention, the lock structure further includes a nut, and the connecting portion is provided with a plurality of threads, and the locking tongue is engaged with the rotating shaft through the nut thread.

[0016] Compared to existing technologies, the lock structure of the present invention includes a housing, a lock cylinder assembly, a knob, a control plate, and a bolt. The control plate includes a first stop and a second stop arranged at an angle, and the control plate can be positioned on the rotating shaft by either abutting the first stop against the limiting surface or by abutting the second stop against the limiting surface. When the first stop abuts against the limiting surface, the second stop can rotate to one side in the rotational space as the rotating shaft rotates; conversely, when the second stop abuts against the limiting surface, the first stop can rotate to the other side in the rotational space as the rotating shaft rotates. Accordingly, the lock structure of the present invention switches the locking direction by changing the arrangement direction of the knob, control plate, and bolt. Its structure is simple and easy to operate, and the locking direction can be changed as needed, which has the advantages of improving application flexibility and ease of use.

[0043] The detailed description and technical content of the present invention are explained below with reference to the accompanying drawings. However, the drawings are provided for reference and illustration only and are not intended to limit the present invention.

[0044] Please refer to Figure 1 and Figure 2 This is a three-dimensional view of the lock structure with reversible locking direction according to the present invention from both sides. The lock structure 1 with reversible locking direction according to the present invention includes a housing 10, a lock cylinder assembly 20, a knob 30, a control plate 40, and a bolt 50. The housing 10 includes a housing base 11 and a panel 12 attached to the housing base 11, and the housing base 11 has a lock cylinder 13. The lock cylinder assembly 20 includes a lock cylinder 21 and a rotating shaft 22. The lock cylinder 21 is rotatably housed in the lock cylinder 13. The rotating shaft 22 passes through the lock cylinder 21 and protrudes from the lock cylinder 13.

[0045] Furthermore, the knob 30 is attached to the panel and is detachably connected to the lock cylinder. In this embodiment, the knob 30 includes a pivot 31 and a lever 32 connected to the pivot 31. The pivot 31 has a lock hole 310. The pivot 31 is detachably connected to the lock cylinder 21. The control plate 40 and the latch 50 are engaged with the rotating shaft 22 at a position protruding from the lock cylinder 13 and rotate with the rotating shaft 22.

[0046] In this embodiment, the lock structure 1 further includes an operating assembly 60. Furthermore, the panel 12 is provided with multiple slots 120. The operating assembly 60 is disposed within the panel 12, with some portions of the slots 120 exposed. Accordingly, the user can use a key (not shown) to insert into the keyhole 310, or use the operating assembly 60 to unlock the lock, thereby causing the lock cylinder assembly 20 to rotate.

[0047] Please refer to another source. Figure 3 This is a combined cross-sectional view of the lock structure with changeable locking direction according to the present invention. In this embodiment, the control piece 40 is fixed on the rotating shaft 22. In addition, the lock cylinder 13 has a rotation space 130 and a limiting surface 131 located on one side of the rotation space 130 at one end face away from the panel 12.

[0048] Specifically, the control piece 40 includes a first stop portion 41 and a second stop portion 42 spaced apart and arranged at an angle. The control piece 40 can be positioned on the rotating shaft 22 such that the first stop portion 41 abuts against the limiting surface 131, or the second stop portion 42 abuts against the limiting surface 131. When the first stop portion 41 abuts against the limiting surface 131, the second stop portion 42 can rotate to one side in the rotation space 130 as the rotating shaft 22 rotates. Conversely, when the second stop portion 42 abuts against the limiting surface 131, the first stop portion 41 can rotate to the other side in the rotation space 130 as the rotating shaft 22 rotates.

[0049] In this embodiment, the control plate 40 is configured as a rhomboid plate to reduce the space required for rotation. The control plate 40 includes a rotating portion 43 located between the first stop portion 41 and the second stop portion 42. Furthermore, the first stop portion 41 and the second stop portion 42 are configured as planes to facilitate abutment against the limiting surface 131. The rotating portion 43 is configured as an arc surface to facilitate the rotation of the control plate 40.

[0050] Please take another photo. Figure 4 and Figure 5 This is a schematic diagram illustrating the first rotation direction of the lock structure 1 of the present invention, which allows for changing the locking direction. The locking direction of the lock structure 1 can be switched by changing the orientation of the knob 30, the control plate 40, and the bolt 50. In this embodiment, the lock structure 1 is installed on the right side of a cabinet door (not shown). The lock structure 1 is opened by rotating the knob 30 in a first direction 2, which causes the lock cylinder assembly 20 to rotate in that first direction 2. At this time, the control plate 40 and the bolt 50 rotate along with the lock cylinder assembly 20 in the first direction 2, thereby disengaging the bolt 50 from the lock on the cabinet door.

[0051] Please take photos at the same time. Figure 6 This is a cross-sectional view of the first rotation direction of the lock structure of the present invention, which can change the locking direction. In this embodiment, the lock structure 1 is positioned on the rotating shaft 22 such that the first stop 41 of the control piece 40 abuts against the limiting surface 131 (see reference). Figure 3 Furthermore, when the lock structure 1 rotates in the first direction 2, the second stop 42 of the control piece 40 can rotate in the rotation space 130 in the first direction 2 until it abuts against the limiting surface 131.

[0052] Please refer to Figure 7 and Figure 8This is an exploded perspective view of the lock structure 1 of the present invention, which allows for changing the locking direction. As mentioned above, the locking direction of the lock structure 1 of the present invention can be switched by changing the orientation of the knob 30, the control plate 40, and the bolt 50. To switch the locking direction, the bolt 50 and the control plate 40 must first be detached from the rotating shaft 22. In this embodiment, the rotating shaft 22 passes through the lock cylinder 21 and has a locking part 221 and a connecting part 222 at one end protruding from the lock cylinder 13. In this embodiment, the locking part 221 is a rectangular block. The control plate 40 has a rectangular hole 400. The control plate 40 engages with the locking part 221 through the rectangular hole 400 and is positioned on the rotating shaft 22, rotating with the rotating shaft 22.

[0053] Furthermore, the latch 50 is detachably fixed to the coupling portion 222 and rotates with the rotating shaft 22. The latch 50 includes a fixed section 51 and a locking section 52. The fixed section 51 is provided with an opening 510 and is fitted onto the rotating shaft 22 through the opening 510. The locking section 52 connects to the fixed section 51 and protrudes from one side of the housing 11. Moreover, the lock structure 1 of the present invention also includes a nut 70. The coupling portion 222 is provided with a plurality of threads 223. The latch 50 is engaged with the rotating shaft 22 by the nut 70 engaging the threads 223.

[0054] Please refer to Figure 9 and Figure 10 This is a schematic diagram of another embodiment of the lock structure with a changeable locking direction according to the present invention. The present invention also provides a lock structure 1' that changes the locking direction. In practical use, as... Figure 9 As shown, first rotate knob 30' 180 degrees to the other side, causing wrench 32' to rotate from right to left. Next, assemble control piece 40' into the rotating shaft 22. In this embodiment, to change the installation angle of control piece 40', control piece 40' is positioned on the rotating shaft 22 with its second stop 42' abutting against the limiting surface 131. Subsequently, similarly rotate latch 50' 180 degrees to the other side, causing locking section 52' to rotate from right to left. Finally, screw nut 70 in to secure control piece 40' and latch 50'.

[0055] Please continue reading. Figure 11 and Figure 12 This is a three-dimensional view of the lock structure with changeable locking direction according to another embodiment of the present invention, showing its appearance from two sides. Figure 11 As shown, in this embodiment, the lock structure 1' is used to be installed on the left side of a cabinet door (not shown). Also, referring to... Figure 12 In this embodiment, when the second stop 42' abuts against the limiting surface 131, the first stop 41' rotates in the rotation space 130 in the other direction as the rotating shaft 22 rotates.

[0056] Please continue reading. Figure 13 and Figure 14 This is a schematic diagram and a cross-sectional view in the second rotation direction of another embodiment of the lock structure with changeable locking direction according to the present invention. Figure 13 As shown, the lock structure 1' is opened by rotating the knob 30' in a second direction 3, which causes the lock cylinder assembly 20 to rotate in that second direction 3. At this time, the control plate 40' and the bolt 50' rotate along with the lock cylinder assembly 20 in the second direction 3, thereby disengaging the bolt 50' from the lock on the cabinet door. Furthermore, as... Figure 14 As shown, after the lock structure 1 rotates in the first direction 2, the control piece 40' rotates with the rotating shaft 22 until it stops when the first stop 41' abuts against the limiting surface 131.
