Technical Field
[0001] The utility model relates to the technical field of pry-proof padlocks, in particular to a pry-proof padlock. Background Art
[0002] Padlocks are the oldest and largest family in the world of locks. It can be said that other locks are derived from padlocks. The padlock body is equipped with a ring-shaped or "I"-shaped metal stem, namely the "lock beam", which can be buckled to the lock body directly through the lock beam to form a closed lock. Due to the structural characteristics of the padlock, the padlock is convenient and flexible to use and has a wide range of uses. It can replace other locks, while other locks cannot replace padlocks. It is an ideal anti-hazard lock, but the padlock must be buckled with the convex perforated parts of the closed object to play a locking role. It does not have the function of closing and opening inside and outside, so it cannot be used in some occasions. For example, in some occasions where the decorative requirements are high or matching locks are required, padlocks are generally not suitable. With the development of society, both companies and individuals have higher and higher requirements for the safety of their own items, and the requirements for locks are also improved, so anti-pry padlocks have appeared;
[0003] The existing anti-pry padlock can only prevent the padlock from being pried open, but cannot protect the anti-pry padlock body, which may cause the padlock to be violently smashed open by an outsider with a hard object, resulting in damage to the anti-pry lock body and then loss of items. At the same time, the anti-pry padlock hole is exposed to the air for a long time, which may cause dust particles in the air to enter the interior, making it impossible to open the anti-pry padlock with a key, thereby reducing the service life of the anti-pry padlock.

[0022] like Figure 1-5 As shown, a pry-proof padlock comprises a pry-proof lock body 2, a U-shaped ring 3 and a padlock cylinder 11, a keyhole 8 is provided at the bottom end of the pry-proof lock body 2, a protective shell 1 is provided on the outer arc surface of the pry-proof lock body 2, a limiting bottom plate 6 is fixedly installed at the bottom end of the protective shell 1, a dustproof port 7 corresponding to the keyhole 8 is provided on the lower surface of the limiting bottom plate 6, a limiting ring 5 is provided on the upper surface of the protective shell 1 and located above the U-shaped ring 3, and a clamping assembly for limiting the limiting ring 5 is provided on the bottom ends of both sides of the limiting ring 5, the connection method of the pry-proof lock body 2, the U-shaped ring 3 and the padlock cylinder 11 is consistent with the connection method of the pry-proof padlocks on the market, the dustproof port 7 is located directly below the keyhole 8, and the key is inserted into the dustproof port 7, and the key will enter the keyhole 8, and the key can be unlocked by turning it.
[0023] Specifically, the clamping assembly includes a connecting rod 9, a clamping rod 10, a fixing column 12 and a compression spring 16. The connecting rod 9 is fixedly mounted on the bottom end of one side of the limiting ring 5. The compression spring 16 is fixedly mounted on one end of the clamping rod 10 close to the padlock cylinder 11. One end of the fixing column 12 is fixedly connected to the compression spring 16, and the other end of the fixing column 12 is fixedly arranged inside the padlock cylinder 11. In the above design, the clamping rod 10 is fixedly connected to the fixing column 12 through the compression spring 16, thereby ensuring that the clamping rod 10 is connected to the padlock cylinder 11 through the fixing column 12, and the clamping rod 10 moves outward under the spring force of the compression spring 16, thereby ensuring that the clamping rod 10 can contact the connecting rod 9.
[0024] Specifically, an arc column 13 is fixedly provided at one end of the clamping rod 10 away from the padlock cylinder 11, a clamping interface 14 corresponding to the arc column 13 is provided on the outer arc surface of the connecting rod 9, and a ball head is provided at the bottom end of the connecting rod 9. According to the above design, when the connecting rod 9 moves downward and contacts the arc column 13, the arc column 13 is squeezed, so that the clamping rod 10 and the arc column 13 squeeze the compression spring 16 to move toward the fixed column 12, and at this time, the compression spring 16 always gives an outward thrust to the clamping rod 10 and the arc column 13, and when the arc column 13 contacts the clamping interface 14, it is clamped into the inside of the clamping interface 14 under the action of the thrust, thereby fixing the connecting rod 9.
[0025] Specifically, two groups of connecting rods 9 are slidably arranged inside the protective shell 1, and two groups of clamping rods 10 are rotatably arranged inside the limiting bottom plate 6. According to the above design, after the U-shaped ring 3 is locked, the two groups of connecting rods 9 are inserted into the protective shell 1, and the two groups of connecting rods 9 are fixed by clamping the arc column 13 into the card interface 14, so that the anti-pry lock body 2 and the protective shell 1 are fixed in position, and the limiting ring 5 covers the U-shaped ring 3 to prevent the protective shell 1 from falling from the outside of the anti-pry lock body 2, and to prevent the thief from using hard objects to violently knock the anti-pry lock body 2, thereby further improving the safety of the anti-pry lock body 2 when in use.
[0026] Specifically, the padlock cylinder 11 is rotatably arranged inside the anti-pry lock body 2, and a moving groove 15 corresponding to the clamping rod 10 and the arc column 13 is provided inside the anti-pry lock body 2, and another set of moving grooves 15 corresponding to the arc column 13 is provided on the inner side wall of the protective shell 1. With the above design, when unlocking, the padlock cylinder 11 is driven to rotate and the clamping rod 10 is driven to move inside the moving groove 15, thereby driving the arc column 13 to leave the inside of the clamp interface 14, at which time the U-shaped ring 3 will bounce upward, thereby giving the limit ring 5 an upward force, driving the connecting rod 9 away from the arc column 13, at which time the protective shell 1 automatically falls off under the action of gravity, and the limit ring 5 and the connecting rod 9 will also be separated from the inside of the protective shell 1, and the anti-pry lock body 2 can be opened.
[0027] Specifically, a protective pad 4 is fixedly installed at the bottom of the limiting ring 5, and the inner side of the protective pad 4 is in contact with the outer arc surface of the U-shaped ring 3. In the above design, the protective pad 4 is provided to prevent the limiting ring 5 from colliding with the U-shaped ring 3. When a thief uses a hard object to damage the limiting ring 5, the protective pad 4 can reduce the damage to the U-shaped ring 3.
[0028] Specifically, several groups of dustproof brushes are arranged inside the dustproof opening 7, and the several groups of dustproof brushes do not contact the keyhole 8. The above design sets dustproof brushes to prevent dust and particles in the outside air from entering the keyhole 8 without affecting the insertion of the key to unlock.
[0029] Working principle: the anti-pry padlock can be locked by inserting the U-shaped ring 3 into the anti-pry lock body 2, and then the protective shell 1 is put on the anti-pry lock body 2 from the bottom of the anti-pry lock body 2 upwards, and then the limiting ring 5 is inserted into the protective shell 1. At this time, the connecting rod 9 at the bottom of the limiting ring 5 will contact the arc column 13 at one end of the clamping rod 10. The arc column 13 is clamped into the clamping interface 14 to lock the connecting rod 9. At this time, the limiting ring 5 contacts the U-shaped ring 3 through the protective pad 4, providing a downward pressure on the U-shaped ring 3. When the thief uses a hard object to When the anti-pry padlock is violently unlocked, the anti-pry lock body 2 cannot be hit, and only the surface of the U-shaped ring 3 can be hit, and the anti-pry padlock cannot be broken open. When the anti-pry padlock needs to be opened, the key is inserted into the keyhole 8 through the dustproof port 7, driving the padlock cylinder 11 to rotate. At this time, the arc column 13 follows the padlock cylinder 11 to rotate and leave the card interface 14. At this time, the U-shaped ring 3 opens and pops up, and at the same time gives the limit ring 5 an upward force, which can drive the connecting rod 9 to detach from the inside of the protective shell 1, thereby removing the protective shell 1 from the surface of the anti-pry lock body 2.
[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
