Description
Technical Field
[0001] This utility model is a push-button padlock, particularly a push-button padlock used to lock items and provide protection. Background Technology
[0002] To protect valuables or important items, people often use padlocks on the openings of containers containing such items to secure them and prevent theft, damage, or misuse.
[0003] Traditional padlocks typically consist of a hook, a cylinder, and a bolt within a housing. The hook is movable between a locked and unlocked position and has a latch groove on each side. The cylinder is housed within the housing and rotates with the insertion of a key. The bolt, controlled by the cylinder and moved linearly within the housing with the assistance of a return spring, is also located within the housing. When the padlock is locked, the hook is in the locked position, and the bolt engages with the latch grooves to lock the hook, creating a closed locking area between the hook and the housing. When the padlock is unlocked, the user inserts the key into the cylinder and rotates it, causing the cylinder to move the bolt and disengage it from the latch grooves. This allows the hook to move from the locked to the unlocked position, creating an opening on one side of the locked area, thus unlocking the padlock.
[0004] However, since traditional padlocks mainly achieve their locking effect by using a linearly movable bolt and a return spring to engage the hook, some malicious individuals may try to unlock the padlock by striking the housing from the side and simultaneously pulling the hook. This causes the bolt to disengage from the hook upon impact, thus unlocking the padlock. Consequently, the traditional padlock's locking effect is insufficient, and it remains vulnerable to being easily cracked.
[0005] Therefore, a ball bearing padlock is currently sold on the market. This padlock mainly uses a structure of two ball bearings and a push-top rotating block to replace the lock pin and return spring structure inside the traditional padlock. The push-top rotating block is rotatably mounted in the housing, and the outer periphery of the push-top rotating block forms two push tops and two movable grooves. The two push tops are located on opposite sides of the push-top rotating block, and the two movable grooves are located on the other two opposite sides of the push-top rotating block. The two ball bearings are movably mounted inside the housing and located on opposite sides of the push-top rotating block.
[0006] When the padlock is locked, the hook is in the locked position, and the pusher of the pusher block faces the two steel balls, pushing them into the latch slots of the hook to lock the hook. When unlocking the padlock, the user can insert the key into the lock cylinder and turn the cylinder. The pusher block rotates synchronously with the lock cylinder, causing its two movable slots to face the two steel balls. At this time, the two movable slots provide sufficient space for the two steel balls to move, allowing them to disengage from the latch slots of the hook and enter the movable slots as the hook moves from the locked position to the unlocked position, thus unlocking the padlock.
[0007] However, when the padlock is in the unlocked state, the two steel balls enter the movable groove of the push-top rotating block. Therefore, the push-top rotating block and the lock cylinder connected to it cannot rotate due to the restriction of the steel balls. Consequently, the key cannot be removed due to the lock inside the lock cylinder. Furthermore, when the user wants to lock the padlock, the user must move the padlock's latch to the locked position and then rotate the key to engage the steel balls in the latch groove of the lock hook in order to securely lock the padlock and remove the key. Therefore, the padlock is inconvenient to lock and has the problem of the key not being able to be removed when the lock is unlocked.
[0008] In addition, to prevent damage by malicious individuals, padlocks are usually made of a one-piece, high-strength stainless steel housing. However, the internal structure of the housing is quite complex, and stainless steel is difficult to process, resulting in higher production and processing costs. Utility Model Content
[0009] The technical problem this invention aims to solve is that current padlocks are relatively inconvenient to operate.
[0010] The technical solution of this utility model is as follows: To achieve the aforementioned purpose, this utility model provides a push-button padlock that can be operated by a key to switch between a locked state and an unlocked state. The push-button padlock comprises:
[0011] One shell base;
[0012] A locking hook is movably mounted on the housing, and the locking hook can move between a locked position and an unlocked position. The locking hook has a latch end and a set of connecting ends connected together. The latch end and the set of connecting ends respectively form a latch groove. The latch groove of the latch end is opposite to the latch groove of the set of connecting ends.
[0013] A locking assembly is disposed within the housing and located between the locking end and the connecting end of the locking hook. The locking assembly includes a push-up block, a reset member, and two steel balls. The outer periphery of the push-up block forms two push-tops and two movable grooves. The two push-tops are located on opposite sides of the push-up block, and the two movable grooves are located on the other two sides of the push-up block. A mating groove is formed at the bottom of the push-up block. The reset member is disposed between the housing and the push-up block and can drive the push-up block to rotate and reset. The two steel balls are respectively disposed between the push-up block and the locking end and the connecting end of the locking hook.
[0014] A lock cylinder is disposed within the housing. The bottom of the lock cylinder forms a keyhole into which the key can be inserted, and the top of the lock cylinder protrudes to form a core post. The core post of the lock cylinder extends into the mating groove of the push-top rotating block, and the lock cylinder and the push-top rotating block can pivot relative to each other at a certain angle.
[0015] In the locked state, the lock hook is in the locked position, and the two steel balls are respectively located between the two locking grooves of the lock hook and the two push tops of the push-top rotating block. When the key is operated to the unlocked state, the lock cylinder drives the two movable grooves of the push-top rotating block to rotate to the positions corresponding to the two steel balls, so that the lock hook can move to the unlocked position. The key can rotate in the opposite direction to make the core of the lock cylinder pivot relative to the mating groove, so that the key can be pulled out of the keyhole.
[0016] The push-top rotating block has two stop protrusions in its mating groove. These two stop protrusions can restrict the cylinder of the lock cylinder from pivoting relative to each other at a certain angle within the mating groove. In addition, the push-type padlock includes a pusher, which is disposed in the housing and abuts against the bottom of the assembly end of the lock hook. The pusher can push the lock hook from the locked position to the unlocked position when the key is used to unlock it.
[0017] This push-button padlock has the following advantages:
[0018] 1. The key can be removed when the lock is unlocked: The push-button padlock of this utility model can provide the cylinder core to pivot relative to the mating groove of the push-button rotating block, thereby allowing the lock core to pivot in the opposite direction relative to the push-button rotating block when the push-button padlock is unlocked, so that the key can be smoothly pulled out of the keyhole of the lock core.
[0019] 2. Convenient locking operation: When locking the push-button padlock, the hook can be pressed directly to the locking position. At this time, the latch groove of the hook provides sufficient space for the two steel balls to move. The reset component of the latch assembly will simultaneously drive the push-top block to rotate and reset, thereby causing the two push-tops of the push-top block to turn and push against the two steel balls, so that the two steel balls are engaged in the latch groove to achieve the effect of automatic locking. Therefore, the push-button padlock of this utility model can provide users with quick locking by directly pressing the hook, without relying on a key, which can effectively improve the convenience of operation.
[0020] Furthermore, to address the issue of high production and processing costs associated with current padlocks, this utility model's push-button padlock housing comprises a main body, an outer shell, and two side plates. The latch assembly and the lock cylinder are housed within the main body. The outer shell has a through-space, and the main body is housed within this space. The two side plates are detachably mounted on opposite sides of the main body, enclosing the space within the outer shell. The lock hook passes through the outer shell and is mounted within the main body. The key passes through the outer shell and extends into the keyhole of the lock cylinder. This modular housing design allows manufacturers to use different materials for the main body, outer shell, and side plates. By selecting different materials, processing difficulty can be reduced, and manufacturing costs can be lowered. Attached Figure Description

[0032] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means adopted by the present invention to achieve its intended purpose.
[0033] Please see Figure 1 , Figure 2 and Figure 3 This is a preferred embodiment of the push-button padlock of the present invention, which includes a housing 10, a lock hook 20, a lock buckle assembly 30 and a lock cylinder 40.
[0034] like Figure 1 , Figure 2 As shown, the locking hook 20 is movably mounted on the housing 10 and can move between a locked position and an unlocked position. The locking hook 20 has a latch end 21 and a set of connecting ends 22 connected to each other. The latch end 21 and the set of connecting ends 22 respectively form a latch groove 23, and the latch groove 23 of the latch end 21 is opposite to the latch groove 23 of the set of connecting ends 22.
[0035] like Figure 2 , Figure 5 , Figure 8 As shown, the locking assembly 30 is disposed within the housing 10 and located between the locking end 21 and the connecting end 22 of the locking hook 20. The locking assembly 30 includes a push-top rotating block 31, a reset member 32, and two steel balls 33. The outer periphery of the push-top rotating block 31 forms two push-tops 311 and two movable grooves 312. The two push-tops 311 are located on opposite sides of the push-top rotating block 31, and the two movable grooves 312 are located on the other two sides of the push-top rotating block 31. A mating groove 313 is formed at the bottom of the push-top rotating block 31. The reset member 32 is disposed between the housing 10 and the push-top rotating block 31 and can drive the push-top rotating block 31 to rotate and reset. The two steel balls 33 are respectively disposed between the push-top rotating block 31 and the locking end 21 and the connecting end 22 of the locking hook 20.
[0036] like Figure 2 , Figure 3 and Figure 5As shown, the lock cylinder 40 is disposed within the housing 10. The bottom of the lock cylinder 40 forms a keyhole 41 into which the key 60 can be inserted, and the top of the lock cylinder 40 protrudes to form a core post 42. The core post 42 of the lock cylinder 40 extends into the mating groove 313 of the push-up rotating block 31, and as... Figure 8 , Figure 9 , Figure 10 As shown, the lock cylinder 40 and the push-top rotating block 31 can pivot relative to each other at a certain angle.
[0037] Among them, such as Figures 4 to 6 As shown, in the locked state, the locking hook 20 is in the locked position, and the two steel balls 33 are respectively located between the two locking grooves 23 of the locking hook 20 and the two pushing tops 311 of the pushing screw block 31; as Figures 7 to 9 As shown, when the key 60 is operated to the unlocked state, the lock cylinder 40 drives the two movable grooves 312 of the push-top rotating block 31 to rotate to the positions corresponding to the two steel balls 33, so that the lock hook 20 can move to the unlocked position, as shown. Figure 10 , Figure 11 As shown, the key 60 can be rotated in the opposite direction to cause the core post 42 of the lock cylinder 40 to pivot relative to each other in the mating groove 313, so that the key 60 can be pulled out of the keyhole 41.
[0038] like Figure 3 As shown, two stop protrusions 314 are formed in the mating groove 313 of the push-top rotating block 31. The two stop protrusions 314 can restrict the core post 42 of the lock cylinder 40 from pivoting relative to each other at a certain angle in the mating groove 313.
[0039] In addition, such as Figure 2 , Figure 5 , Figure 8 As shown, the push padlock includes a pusher 50, which is disposed inside the housing 10 and abuts against the bottom of the assembly end 22 of the lock hook 20. The pusher 50 can push the lock hook 20 from the locked position to the unlocked position when the key 60 is used to unlock it.
[0040] Furthermore, such as Figure 2 As shown, the housing 10 includes a main body 11, an outer shell 12, and two side plates 13. The latch assembly 30 and the lock cylinder 40 are disposed inside the main body 11. The outer shell 12 has a through-space accommodating space 121. The main body 11 is disposed inside the accommodating space 121 of the outer shell 12. The two side plates 13 are respectively detachably disposed on the left and right opposite sides of the main body 11 and enclose the accommodating space 121 of the outer shell 12. The lock hook 20 can pass through the outer shell 12 and be assembled inside the main body 11. The key 60 can pass through the outer shell 12 and extend into the keyhole 41 of the lock cylinder 40.
[0041] In addition, such as Figure 2 , Figure 5 , Figure 8 As shown, the body 11 has two hook assembly grooves 111, a latch positioning groove 112, two movable channels 113, and a lock cylinder positioning groove 114. The latch positioning groove 112 is located between the two hook assembly grooves 111. The two movable channels 113 are located on both sides of the latch positioning groove 112 and are connected to the two hook assembly grooves 111. The lock cylinder positioning groove 114 is located below the latch positioning groove 112 and is connected to the latch positioning groove 112. The assembly end 22 and the latch end 21 of the hook 20 can be assembled in the hook assembly groove 111 of the body 11. The push-up rotating block 31 and the reset member 32 of the latch assembly 30 are disposed in the latch positioning groove 112. The two steel balls 33 are disposed in the two movable channels 113. The lock cylinder 40 is disposed in the lock cylinder positioning groove 114.
[0042] like Figure 2 As shown, the housing 10 includes two limiting baffles 14, which are detachably arranged above the two movable channels 113.
[0043] like Figures 4 to 6 As shown, when the push-type padlock of this utility model is in the locked state, the lock hook 20 will be in the locked position and compress the push-top member 50, and the two push-tops 311 of the push-top rotating block 31 will be facing the two steel balls 33 respectively, so that the two steel balls 33 will be locked into the two locking grooves 23 of the lock hook 20 under the pushing limit of the two push-tops 311, so that the lock hook 20 cannot move to the unlocked position under the limit of the two steel balls 33.
[0044] like Figures 7 to 9 As shown, when unlocking the push-button padlock, the user can insert the key 60 into the keyhole 41 of the lock cylinder 40 and rotate the key 60 to rotate the lock cylinder 40. The cylinder post 42 of the lock cylinder 40 will push against the stop protrusion 314 in the bottom mating groove 313 of the push-button block 31, and drive the two movable grooves 312 of the push-button block 31 to face the two steel balls 33 respectively, so that the two steel balls 33 can move into the movable grooves 312. This allows the two steel balls 33 to disengage from the locking groove 23 of the hook 20. At this time, the pusher 50 will push the hook 20 from the locked position to the unlocked position, thus enabling the push-type padlock to be in the unlocked state. In the unlocked state, the connecting end 22 of the hook 20 will abut and limit the corresponding steel ball 33, thereby causing the steel ball 33 to engage in the movable groove 312 of the pusher block 31, preventing the pusher block 31 from rotating. Figure 10 , Figure 11As shown, since the mating groove 313 of the push-top rotating block 31 can provide the core column 42 to pivot at a certain angle inside, the user can pull out the key 60 by rotating the key 60 in the opposite direction to reset the lock inside the lock cylinder 40.
[0045] like Figures 4 to 6 As shown, when a user wants to lock the push-button padlock, the user can directly press the hook 20 to move the hook 20 from the unlocked position to the locked position. At this time, when the hook 20 moves to the locked position, the latch groove 23 of the hook 20 will connect with the movable channel 113 of the body 11, allowing the two steel balls 33 to move into the latch groove 23 of the hook 20. At this time, the reset member 32 will drive the push-top rotating block 31 to rotate and reset, so that the push-top 311 of the push-top rotating block 31 pushes the two steel balls 33 respectively, so that the two steel balls 33 are respectively engaged in the corresponding latch groove 23, thereby making the push-button padlock present a locked state. Therefore, the push-button padlock of this utility model can provide users with the ability to quickly lock by directly pressing the hook 20 without relying on the key 60, which can effectively improve the convenience of operation.
[0046] In addition, such as Figure 2 As shown, the push-button padlock of this utility model, through the modular housing 10 design, allows manufacturers to use different materials to make the body 11, outer shell 12, and side plate 13. For example, in a preferred embodiment of the push-button padlock of this utility model, the body 11 can be made of aluminum alloy, which is easier to process and has a lower cost, while the outer shell 12 and side plate 13 can be made of stainless steel, which has a higher structural strength. During assembly, the stainless steel outer shell 12 and side plate 13 are used to cover the aluminum alloy body 11 to provide sufficient structural strength, thereby effectively reducing processing and manufacturing costs while providing sufficient structural strength.
[0047] In summary, the push-button padlock of this invention, through the mating groove 313 structure design of the push-button rotating block 31 of the latch assembly 30, allows the push-button padlock to pivot in the opposite direction relative to the push-button rotating block 31 to remove the key 60 when in the unlocked state. When locking, the push-button rotating block 31 can be driven to rotate through the reset member 32 to achieve an automatic locking effect, which can effectively improve the operational convenience of the push-button padlock. In addition, the push-button padlock of this invention, through the detachable housing 10 structure design, allows manufacturers to select different materials according to the parts, thereby reducing the processing and manufacturing costs of the push-button padlock.
