BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the combined structure of the utility model;
[0011] Figure 2 It is a schematic diagram of the exploded structure of the utility model. DETAILED DESCRIPTION
[0012] like Figure 1-Figure 2 As shown, a password padlock structure includes a female row 1, a male row 2 and a lock ring 3, wherein the lock ring 3 has a locking end 4 and a limiting end 5, and the female row 1 has a longitudinal hole 6 and a transverse hole 7 that are perpendicular to each other and intersect in a cross-shaped structure. The longitudinal hole 6 and the transverse hole 7 are equivalent to forming a cross-shaped cavity. The female row 1, the male row 2 and the lock ring 3 are optimized designs based on the basic structure of the existing products, and no further elaboration or limitation is made on them. It should be pointed out that the lock ring 3 is a semicircular arc structure, with its two ends facing the same direction and the shapes of the two ends being different, which is also a mature technical means.
[0013] The transverse hole 7 forms a groove on the outer wall of the female row 1, and a button 8 and a lock gate 9 of interlocking assembly are arranged at the groove, and an annular limit groove 10 is arranged on the limit end 5. The groove is one end of the cross-shaped cavity, which is specially used for placing the button 8, and it is also convenient for the user to press the button 8 there, thereby driving the internal interlocking action. The setting of the limit groove 10 is mainly to block the limit and prevent the limit end 5 of the lock ring 3 from detaching from the female row 1.
[0014] The lock gate 9 is provided with an opening whose diameter is larger than the diameter of the limiting end 5. The limiting end 5 extends into the longitudinal hole 6 and passes through the opening of the lock gate 9. The male row 2 is inserted into the end of the transverse hole 7 away from the button 8, and the male row 2 and the lock gate 9 are in abutment and linkage. The male row 2 also has a tendency to elastically return to the lock gate 9 side. The male row 2 is also provided with a locking seat 11 on the side away from the lock gate 9. The locking seat 11 is provided with a slot 12, and the slot 12 has side notches and upper notches for the female row 1 to be axially inserted along the transverse hole 7 and engaged with the locking end 4, respectively. The locking end 4 and the male row 2 are elastically engaged and limited in the locking seat 11. A limiting pin 13 is also provided in the female row 1, and the limiting pin 13 extends into the limiting slot 10 and blocks and limits the limiting end 5. It also includes a code wheel 14 mounted on the female row 1 and matched with the male row 2, the code wheel 14 is sleeved between the female row 1 and the locking seat 11, a spring 15 is provided between the code wheel 14 and the lock gate 9, and a spring 2 is provided between the male row 2 and the locking seat 11. The locking end 4 is provided with a hook groove 16, and one end of the male row 2 has a hooking portion 17 that is engaged with the hook groove 16, and the hooking portion 17 is hook-shaped.
[0015] The lock ring 3 passes through the lock gate 9 inside the female row 1. The lock gate 9 and the button 8 are connected at the card point, and as a whole, they move axially in the circular hole of the female row 1. There are two points on the front end of the lock gate 9 acting on the spring 15. When the button 8 moves into the hole along the female row 1, the front end of the lock gate 9 compresses the spring 15. At this time, the lock gate 9 hole and the female row 1 hole are concentric. The middle position of the lock gate 9 is against the front end of the male row 2. When the password is correct, the movement of the button 8 will also push the movement of the male row 2, so that the protrusion on the male row 2 is separated from the notch on the lock ring 3, that is, the hook groove 16 and the hooking part 17. In this way, the lock ring 3 opens the lock under the action of other springs. When the lock ring 3 moves up to a certain position in the lock ring 3 hole of the female row 1, the limit pins 13 placed in the two holes on the female row 1 will block the plane of the lock ring 3, preventing the lock ring 3 from continuing to move up. Otherwise, the lock ring 3 will directly separate from the female row 1, and the lock will be scrapped.
[0016] The male row 2 is also provided with a side notch, in which a spring 2 is placed. Under the force of the spring 2, the male row 2 moves toward the direction of the button 8, pushing the lock gate 9 and the button 8 outward together. In this way, the hole on the lock gate 9 is misaligned with the lock ring 3 on the female row 1, and the lock gate 9 is in a state of locking the lock ring 3. When the lock ring 3 is locked, the lock ring 3 moves downward along the female row 1 under the action of an external force, pushing the lock gate 9 and the male row 2 to compress the spring 15 and the spring 2 at the same time. Note that the spring compressed by the lock gate 9 here has two functions, and the compression and elastic reset of the lock gate 9 are the key. At the same time, the spring 15 also has the function of pressing against the inner wheel of the password. The structure of the password lock is a common structure on the market at present, and it will not be specifically explained here. The female row 1 is extended in the axial direction of the transverse hole 7 to form a ring-shaped extension part, and the spring 15 is arranged on the inner side of the extension part. The design of the extension part provides space for the installation of the spring 15.
