[0032] like Figures 1 to 6 The specific embodiment shown, wherein Figures 1 to 5 As shown, the present invention discloses a padlock structure, including a lock shell 10, a lining 20, and a lock hook 30; the lock shell 10 has an opening 11 at the bottom for connecting with the lining 20, and the lock shell 10 has a through hole 12 and a countersunk hole 13 at the top, the long arm end 31 of the lock hook 30 passes through the through hole 12 to connect with the lining 20, and the short arm end 32 of the lock hook 30 is connected with the countersunk hole 13.

[0033] Among them, by providing an opening 11 at the bottom of the lock shell 10, the integrity of the product is ensured, there is no gap around, the structure is more stable and it is convenient to do waterproofing.

[0034] Specifically, Figures 1 to 3 As shown, the lining 20 is provided with a deep hook hole 21 at a position corresponding to the through hole 12, and the long arm end 31 of the lock hook 30 passes through the through hole 12 and is connected to the deep hook hole 21; the top of the lining 20 is also provided with a groove 22 located on the outer periphery of the deep hook hole 21, and a special-shaped sealing ring 50 is embedded in the groove 22, so that when the lining 20 and the lock shell 10 are tightly matched, the special-shaped sealing ring 50 is pressed, so that the pressed special-shaped sealing ring 50 does not move when the lock hook 30 moves up and down, and at the same time maintains a tight fit, thereby improving the waterproof and dustproof effect.

[0035] Specifically, Figures 1 to 3As shown, the lining 20 is provided with a shallow hook hole 23 at a position corresponding to the countersunk hole 13, and the countersunk hole 13 and the shallow hook hole 23 are connected by a half-thread screw 50. The half-thread screw 50 is also sleeved with an annular sealing ring 60. The annular sealing ring 60 is sleeved on the half-thread screw 50, which can prevent the half-thread screw 50 from loosening and also play a waterproof role. The use of the half-thread screw 50 can effectively prevent the thread from damaging the annular sealing ring 60 when disassembling the screw.

[0036] Furthermore, the short arm end 32 of the lock hook 30 is embedded in the countersunk hole 13 and is located above the half-thread screw 50, so that after the lock hook 30 is pressed into the lock housing 10, the half-thread screw 50 is blocked by the short arm end 32 of the lock hook 30, and the half-thread screw 50 cannot be removed when the padlock is closed, effectively ensuring the safety of the padlock after it is locked. At the same time, the present invention effectively solves the problem that the front and rear covers of the current padlocks on the market mostly use buckles and pins to fit tightly, which causes the pins to be exposed, affecting the appearance and even posing the risk of falling off.

[0037] Specifically, Figures 1 to 3 As shown, a boss 29 is further provided at the bottom of the lining 20 , and an annular groove 15 is provided at a position of the lock housing 10 corresponding to the boss 29 , and the boss 29 is cooperatively connected with the annular groove 15 .

[0038] A bottom waterproof ring 90 is provided between the boss 29 and the annular groove 15, which plays the role of bottom sealing and compensating the internal matching gap, thereby improving the waterproof and dustproof effect.

[0039] Furthermore, in this embodiment, the material of the bottom waterproof ring 90 is rubber.

[0040] Specifically, Figures 1 to 5 As shown, the lining 20 is also connected to a locking tongue 70 and a lining cover 80; the lining 20 is provided with an inner cavity 24 for accommodating the lining cover 80, and the upper end of the inner cavity 24 is also provided with a first embedding groove 25 for embedding the locking tongue 70, which saves space and is firmly connected.

[0041] Among them, the inner side of the lining cover 80 is also provided with an embedding cavity 81 for connecting with the locking tongue 70, and the left side of the lining cover 80 is also provided with a pressing piece 82 and a check card 83. The positions of the lining 20 corresponding to the pressing piece 82 and the check card 83 are respectively provided with a second embedding groove 26 and a third embedding groove 27, and the first embedding groove 25, the second embedding groove 26, and the third embedding groove 27 are all connected to the deep hook hole 21.

[0042] Among them, the lock shell 10 is also provided with a positioning column 14 at the top of the opening 11, the lining 20 is provided with a positioning hole 28 corresponding to the position of the positioning column 14, and the lining cover 80 is also provided with a positioning groove 84. The positioning column 14 passes through the positioning hole 28 and is connected to the positioning groove 84, which plays a role in positioning the lining cover 80 to prevent the lining cover 80 from being lifted and causing the lock hook 30 to fall out of the lock shell 10.

[0043] Among them, a guide bevel 311 is provided at the bottom of the long arm end 31 of the lock hook 30, and a limit groove 312 is provided above the guide bevel 311. The limit groove 312 is connected to the check card 83. A stop groove 313 is also provided on the long arm end 31 of the lock hook 30, and the stop groove 313 is connected to the lock tongue 70. During assembly, the guide bevel 311 presses the left end of the lock tongue 70 into the inner cavity 24, and then the lock hook 30 is rotated 90° clockwise and then inserted downward to engage the check card 83 with the limit groove 312. The structure is simple and the connection is firm.

[0044] Among them, in this embodiment, the limit groove 312 is a right angle, the inner side of the check card 83 is a slope, and the outer side is a straight surface. The slope makes assembly simpler and more labor-saving, and the straight surface is connected with the right angle, and the connection is more secure, which can make the limit groove 312 and the check card 83 more securely connected.

[0045] The padlock structure of the present invention is applicable to other locks with similar structures, such as smart padlocks, smart bicycle locks, smart motorcycle locks, etc.

[0046] like Figure 6 As shown, the present invention also discloses a method for assembling a padlock structure, comprising the following steps:

[0047] S1, insert the lock tongue into the first embedding groove, and then put the lining cover into the inner cavity to match with the lock tongue;

[0048] The lining cover is placed in the inner cavity to cooperate with the lock tongue. At this time, the embedding cavity cooperates with the lock tongue, and the pressing piece and the check card are respectively located in the second embedding groove and the third embedding groove.

[0049] S2, insert the special-shaped sealing ring into the groove, and then push the upper end of the liner into the opening of the lock shell;

[0050] S3, insert the long arm end of the lock hook through the through hole into the deep hook hole, and the guide bevel at the bottom of the long arm end of the lock hook presses the left end of the lock tongue into the inner cavity. At this time, turn the lock hook clockwise 90° and then insert it downward to make the check card engage with the limit groove;

[0051] Among them, the lock hook is rotated 90° clockwise and then inserted downward. The guide angle of the lock hook hits the inclined surface of the check card, causing the lining cover to naturally lift up. Then, the lock hook continues to be pushed until the check piece of the lining cover is stuck in the limiting groove of the lock hook. At this time, the lining cover falls and is no longer higher than the lining.

[0052] S4, put the bottom waterproof ring onto the lining, and then push the lining completely into the opening of the lock shell. At this time, the positioning column passes through the positioning hole and connects with the positioning groove;

[0053] Among them, the positioning column at the top of the lock shell passes through the lining and is stuck in the lining cover to prevent the lining cover from being lifted again and causing the lock hook to fall out of the lock shell. In addition, the inner surface of the lock shell cooperates with the lining to further ensure that the lining cover will not be lifted and fall off during the movement of the lock hook, and the limiting groove of the lock hook is a right angle, which can be effectively stuck by the straight surface of the check card on the lining cover to prevent the lock hook from being pulled out again.

[0054] S5, put the annular sealing ring on the half-thread screw, and then tighten the half-thread screw through the countersunk hole and the shallow hook hole to complete the assembly of the padlock.

[0055] The above assembly method is simple to operate and the components are firmly connected.

[0056] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
