[Diagram 2] FIG. 2 is a cross-sectional view of the password lock of the present invention in an unlocked state. [Diagram 3] FIG. 2 is an explanatory diagram of the password lock of the present invention in a locked state. [Figure 4] FIG. 2 is a cross-sectional view of the password lock of the present invention in a locked state. [Diagram 5] FIG. 5 is a partially enlarged view of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] In order to provide a more detailed and complete description of the present invention, the following detailed description is provided with accompanying drawings. However, these are not the only possible modes for implementing the specific embodiments of the present invention, and the descriptions of directions such as "front", "back", "up", "down", "left", and "right" in the text are provided for ease of understanding and are not intended to be limited to these directions. The same or equivalent functions may be achieved by other implementation methods.
[0015] In this device, the direction in which the accommodating portion 14 is inserted into the engagement hole 211 (i.e., the X-axis) is defined as the left-right direction, the direction in which the dial 15 rotates (i.e., the Y-axis) is defined as the front-back direction, and the direction in which the abutment member 141 is inserted into the accommodating portion 14 (i.e., the Z-axis) is defined as the up-down direction.
[0016] 1 and 2 are explanatory diagrams of the password lock unlocking of the present invention, the password lock includes a first lock part 10 and a second lock part 20, and after the first lock part 10 and the second lock part 20 are locked together, an oval password lock having two locks 30 is formed, as shown in the locking explanatory diagram of the present invention in FIG. 3 and FIG. 4.
[0017] The first locking part 10 is formed with a base 11, a sleeve 12 and a housing part 14, and the sleeve is installed extending from the base 11 toward the second locking part 20 along the X-axis. One end away from the base 11 is connected to the housing part 14, and the lock cylinder 13 is installed so as to penetrate the base 11 and is installed inside the sleeve 12 and the housing part 14. The lock cylinder 13 moves along the X-axis, and a reset member 134 is provided at one end of the lock cylinder 13 through which the base 11 penetrates, and the lock cylinder 13 is moved rightward by the force of the reset member 134, and a plurality of dials 15 are provided on the outer ring wall surface of the sleeve 12 adjacent to the base 11, which is a member for locking the lock cylinder 13 to prevent its movement and for setting a password and performing an unlocking operation. The outer ring wall surface of the accommodating section is configured so that at least one abutment member 141 penetrates along the Y axis, the number of the at least one abutment member 141 is two, and the two abutment members 141 move toward the inside of the accommodating section 14 along the Y axis and abut against the free end of the lock cylinder 13 to move the lock cylinder 13 to the left.
[0018] Further, the reset member 134 has a spring 1342 and a push button 1341, and the spring 1342 is wound around the lock cylinder 13 and connected to the push button 1341 and the inside of the base 11, respectively. The push button 1341 is connected to an end of the lock cylinder 13 via a C-shaped ring, but is not limited thereto. When the push button 1341 is pressed to the right, the spring 1342 is compressed and the lock cylinder 13 moves to the right, and when the push button 1341 is released, a force is generated by the repulsion of the spring 1342, and the lock cylinder 13 and the push button 1341 move to the left.
[0019] The second locking part 20 is provided with another base 21, and the base 21 has an engagement hole 211 that can be fitted to the receiving part 14. At least one pressing member 212 is provided inside the base 21, and the at least one pressing member 212 moves up and down along the Y axis. Taking this embodiment as an example, the number of the at least one pressing member 212 is the same as the number of the at least one abutting member 141, and when the first locking part 10 and the second locking part 20 are locked, the two pressing members 212 and the two abutting members 141 must move in the same direction to accurately press the two abutting members 141 and abut against the free end of the lock cylinder 13. The two pressing members 212 have the function of positioning and engaging the first locking part 10 and the second locking part 20, and prevent internal parts from being damaged due to an incorrect engagement direction or angle.
[0020] Each of the pressing members 212 has a pressing plate 2121 and a spring 2122, and the spring 2122 is connected to the inside of the base 21 and the pressing plate 2121 along the Y axis, respectively. When the two abutting members 141 press the two pressing plates 2121, the two pressing plates 2121 move upward and downward toward the inside of the base 21, respectively, and the two springs 2122 are compressed. When the two abutting members 141 stop pressing the two pressing plates 2121, the two springs 2122 return to their original positions to generate a force, which moves the two pressing plates 2121 toward each other and presses the two abutting members 141.
[0021] The first locking part 10 and the second locking part 20 are respectively provided with two first engagement arms 16 and two second engagement arms 22, and the two first engagement arms 16 extend from both sides of the base 11 of the first locking part 10 in opposite directions along the Z axis for a certain distance, and then bend and extend toward the second locking part 20. The two second engagement arms 22 are installed symmetrically with the two first engagement arms 16 from both sides of the base 21 of the second locking part 20. The design of the engagement arms is such that, in addition to allowing the user to grasp and operate them, when the receiving part 14 is engaged and coupled with the engagement hole 211, each of the first engagement arms 16 and each of the second engagement arms 22 are coupled with each other to form a lock 30, allowing the user to lock two different objects together. In another embodiment, each of the first engagement arms 16 is provided with a fastener groove 161 that engages with the fastener 221 of each of the second engagement arms 22 to improve the overall stability.
[0022] Next, reference is made to Fig. 5, which is a partially enlarged view of Fig. 4. The lock cylinder 13 is a cylindrical body, and an outer ring surface 131, a guide surface 132, and a protrusion 133 are provided at a free end of the lock cylinder 13. The protrusion 133 is located at an end of the lock cylinder 13, and the guide surface 132 is provided between the outer ring surface 131 and the protrusion 133. The diameter of the protrusion 133 is smaller than the diameter of the outer ring surface 131, and the guide surface 132 is inclined in a direction toward the protrusion 133. When the lock cylinder 13 moves to the right, the convex portion 133 is accommodated in the groove 142 in the accommodating portion 14, and the two abutment members 141 abut against the outer ring surface 131, and when the lock cylinder 13 moves to the left, the convex portion 133 moves away from the groove 142, and the two abutment members 141 abut against the guide surface 132.
[0023] At least one locking member 143 is provided near the groove 142. In this embodiment, the at least one locking member 143 is annular and extends from the opening of the groove 142 along the X-axis toward the first locking unit 10. Each of the abutting members 141 is a column and is provided with an annular portion 1411 perpendicular to the longitudinal direction of the abutting members 141. The locking member 143 locks the two annular portions 1411 when the two abutting members 141 approach each other. In another embodiment, each of the locking members 141 is a sphere, and the diameter of the two spheres is the same as the diameter of the annular portion 1411, and the locking member 143 can be directly locked by the locking member 143.
[0024] The embodiment of the present invention will be further described. When performing a locking operation, the user couples the first locking part 10 and the second locking part 20, and moves the lock cylinder 13 rightward via the resetting member 134, and the lock cylinder 13 abuts against the two abutting members 141, and the two abutting members 141 abut against the guide surface 132 to move toward the outside of the receiving part 14. At the same time, the two abutting members 141 press the two pressing members 212 to move in a direction away from each other, and when the two abutting members 141 leave the guide surface 132 and abut against the outer ring surface 131, the user turns the dial 15 to a random state, which locks the movement of the lock cylinder 13 and achieves locking. When performing an unlocking operation, after the user turns the dial 15 to the correct password, the reset member 134 applies force to reset the lock cylinder 13 to the left, and at the same time, the two pressing members 212 press the two abutment members 141, causing the two abutment members 141 to slide toward each other along the inclined surfaces of the guide surface 132, generating another force to move the lock cylinder 13 to the left, and finally the user pulls the first locking part 10 and the second locking part 20 away from each other in opposite directions to complete unlocking.
[0025] From the above, the improved structure of the password lock of the present invention is such that the password lock installs the lock cylinder 13 inside the sleeve 12 and the accommodating portion 14, which prevents the password lock from being affected by or damaged by external forces, and the complex locking mechanism reduces the risk of tools being used to break the lock and improves theft prevention. Furthermore, the cooperative action of the two pressing members 212 through the two abutment members 141 can enable the user to unlock the lock quickly and provide a more convenient operating experience.
