DETAILED DESCRIPTION

[0021] For the purpose of making the content of the present application complete and perfect, the following drawings are provided and the preferred embodiments are described in detail. However, the present application is not limited to the following embodiments. The terms "front", "back", "up", "down", "left", "right" and the like are used for the convenience of understanding and are not limited to these directions. The same or equivalent functions can be achieved by other embodiments.

[0022] The present application takes the direction of inserting the accommodation portion 14 into the buckling hole 211 (i.e. X-axis) as the left-right direction, the rotating direction of the dial 15 (i.e. Y-axis) as the front-back direction, and the direction of inserting the abutting member 141 into the accommodation portion 14 (i.e. Z-axis) as the up-down direction.

[0023] Please refer to Figure 1 and Figure 2 , which is a schematic diagram of unlocking the password lock of the present application. The password lock comprises a first lock portion 10 and a second lock portion 20. When the first lock portion 10 and the second lock portion 20 are locked together, an oval-shaped password lock with double lock catches 30 is formed as shown in Figure 3 and Figure 4 , which is a schematic diagram of locking the password lock of the present application.

[0024] The first lock portion 10 is provided with a first base portion 11, a sleeve 12 extending from the first base portion 11 along the X axis to the second lock portion 20, and a receiving portion 14 connected to an end of the sleeve 12 away from the first base portion 11. A lock cylinder 13 is arranged inside the sleeve 12 and the receiving portion 14 and can move along the X axis. An end of the lock cylinder 13 penetrating the first base portion 11 is provided with a reset member 134. The reset member 134 is forced to move the lock cylinder 13 to the right. A plurality of dials 15 are arranged on the outer circumferential surface of the sleeve 12 close to the first base portion 11 as components for locking the lock cylinder 13 to prevent movement, setting a password, and unlocking operation. The outer circumferential surface of the receiving portion 14 is provided with at least one abutting member 141 along the Y axis. The at least one abutting member 141 can move linearly along a direction perpendicular to the movement direction of the lock cylinder 13. In the embodiment, the number of the at least one abutting member 141 is two. The two abutting members 141 move along the Y axis to the inside of the receiving portion 14 and abut the free end of the lock cylinder 13 to drive the lock cylinder 13 to move to the left.

[0025] In addition, the reset member 134 is provided with a spring 1342 and a button 1341. The spring 1342 is wound around the lock cylinder 13 and connected to the button 1341 and the inside of the first base portion 11, respectively. The button 1341 can be connected to the end of the lock cylinder 13 through a C-shaped ring, but is not limited thereto. When the button 1341 is pressed to the right, the spring 1342 is compressed and the lock cylinder 13 moves to the right. When the button 1341 is released, the spring 1342 rebounds to generate a force to move the lock cylinder 13 and the button 1341 to the left.

[0026] The second lock portion 20 is provided with a second base portion 21 provided with a clamping hole 211 matched with the receiving portion 14. The inside of the second base portion 21 is provided with at least one pushing member 212 moving up and down along the Y axis. In the embodiment, the number of the at least one pushing member 212 is the same as that of the at least one abutting member 141. When the first lock portion 10 and the second lock portion 20 are clamped, the two pushing members 212 respectively push the two abutting members 141 to make the two abutting members 141 close to each other. Since the movement directions of the two pushing members 212 and the two abutting members 141 must be consistent, the two pushing members 212 can accurately push the two abutting members 141 to abut the free end of the lock cylinder 13. The two pushing members 212 have the function of positioning the clamping of the first lock portion 10 and the second lock portion 20 to avoid damage to internal parts due to incorrect clamping direction and angle.

[0027] Each of the pushing members 212 has a push plate 2121 and a spring 2122. The spring 2122 is connected to the interior of the second base 21 and the push plate 2121 along the Y-axis. When the two abutting members 141 push the two push plates 2121, the two push plates 2121 move upward and downward into the interior of the second base 21, respectively, and the two springs 2122 are compressed. If the two abutting members 141 stop pushing the two push plates 2121, the two springs 2122 reset and generate a force to move the two push plates 2121 in opposite directions and push the two abutting members 141.

[0028] The first locking part 10 and the second locking part 20 are also provided with two first fastening arms 16 and two second fastening arms 22 respectively. The two first fastening arms 16 extend from the two sides of the first base 11 of the first locking part 10 along the Z-axis in opposite directions for a certain distance, and then bend and extend towards the second locking part 20. The two second fastening arms 22 are arranged symmetrically to the two first fastening arms 16 from the two sides of the second base 21 of the second locking part 20. In addition to making it easy for the user to hold and operate, when the receiving part 14 is engaged with the fastening hole 211, each of the first fastening arms 16 and each of the second fastening arms 22 are combined to form a lock 30, which allows the user to lock two different objects together. In other embodiments, each of the first fastening arms 16 is provided with a fastening groove 161, which is engaged with a fastening member 221 of each of the second fastening arms 22 to improve the overall stability.

[0029] Please continue reading. Figure 5 ,for Figure 4 The enlarged view shows that the lock cylinder 13 is a cylinder, and the free end of the lock cylinder 13 is provided with an outer ring surface 131, a guide surface 132 and a protrusion 133. The protrusion 133 is located at the 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, so that the guide surface 132 is inclined towards the protrusion 133. When the lock cylinder 13 moves to the right, the protrusion 133 is accommodated in a groove 142 in the accommodating part 14, and the two abutting members 141 abut against the outer ring surface 131. If the lock cylinder 13 moves to the left, the protrusion 133 leaves the groove 142, and the two abutting members 141 abut against the guide surface 132.

[0030] In addition, at least one stopper 143 is arranged near the groove 142, in the embodiment, the at least one stopper 143 is a circular ring cylinder, and is arranged to extend from the groove 142 to the first lock part 10 along the X axis, wherein each abutting piece 141 is a column and is provided with a ring-shaped piece 1411 perpendicular to the long axis direction of each abutting piece 141, and the stopper 143 is used to stop the two ring-shaped pieces 1411 when the two abutting pieces 141 are close to each other. In other embodiments, each abutting piece 141 is a sphere, and the diameters of the two spheres are the same as the diameter of the ring-shaped piece 1411, so that the two spheres can be directly stopped by the stopper 143.

[0031] Further, when the locking operation is performed, the user combines the first lock part 10 and the second lock part 20, and moves the lock core 13 to the right through the reset piece 134, the lock core 13 abuts against the two abutting pieces 141, so that the two abutting pieces 141 are moved to the outside of the accommodating part 14 by leaning against the guide surface 132, and at the same time, the two abutting pieces 141 push the two pushing pieces 212 to move away from each other, when the two abutting pieces 141 abut against the outer ring surface 131 by leaving the guide surface 132, the user disarranges the dials 15 to lock the mobility of the lock core 13, and the locking is achieved. When the unlocking operation is performed, after the user turns the dials 15 to the correct password, the reset piece 134 applies force to reset the lock core 13 to the left, and at the same time, the two pushing pieces 212 push the two abutting pieces 141, so that the two abutting pieces 141 slide along the inclined surface of the guide surface 132 to each other, thereby generating another driving force to move the lock core 13 to the left, and finally the user pulls the first lock part 10 and the second lock part 20 away from each other in the opposite direction, and the unlocking is completed.

[0032] As known from the above, the improved structure of the password lock of the utility model, the password lock sets the lock core 13 in the pipe sleeve 12 and the accommodating part 14 to avoid external force influence or damage, and the complex locking mechanism can reduce the use of tools to crack, thereby improving the anti-theft performance, in addition, through the cooperation of the two abutting pieces 141 and the two pushing pieces 212, the user can quickly unlock, and the operation experience is more convenient.
