Description

Technical Field

[0001] The utility model relates to the technical field of padlocks, and particularly relates to a padlock. Background Art

[0002] Traditional locks mostly rely on the matching rotation of the key and the lock core to realize the telescoping of the lock tongue, and then relieve the restriction of the lock tongue on the lock beam. Although this traditional unlocking method is convenient, its stability is poor. After long-term use, unlocking will become stuck and not smooth enough. Moreover, in the way of directly pushing the lock tongue by rotating the lock core, the entire force is on the mechanical key, which will cause users to apply a greater force to unlock, and the user experience will be relatively poor. Content of the Utility Model

[0003] The utility model aims to provide a technical solution that can solve the above problems to overcome the above deficiencies.

[0004] A padlock includes a lock body and a lock beam provided on the lock body, and further includes a lock tongue provided in the lock body for restricting the lock beam from bouncing up to keep the lock beam in a locked state. An elastic member is provided in the lock body to keep the lock tongue tightly locking the lock beam. The lock body is provided with a mechanical lock core for driving the lock tongue to separate from the lock beam so that the lock beam is in an unlocked state. The mechanical lock core includes a lock core shell fixedly provided in the lock body and a lock cylinder provided in the lock core shell and rotatably connected thereto, and further includes a mechanical key cooperating with the lock cylinder. Above the lock cylinder, there is a push shaft that is slidably matched with the lock body up and down for pushing the lock tongue to separate from the lock beam. A shaft sleeve is formed on the upper part of the lock cylinder for the lower part of the push shaft to penetrate into. An inclined strip-shaped hole is formed on the shaft sleeve. A pin is provided on the push shaft and is engaged in the strip-shaped hole and can move along the strip-shaped hole under the rotation of the push shaft so that the push shaft moves upward.

[0005] For a padlock as described above, the front end of the pin extends out of the strip-shaped hole to form a guiding portion. A limiting groove is formed in the lock core shell to restrict the rotation of the push shaft so that when the shaft sleeve acts on the pin, the push shaft moves axially, and then pushes the lock tongue to separate from the lock beam.

[0006] For a padlock as described above, the guiding portion is conical. Correspondingly, the cross-section of the limiting groove is the same as that of the guiding portion.

[0007] For a padlock as described above, an inclined surface is formed on the lock tongue for the push shaft to push so that the lock tongue separates from the lock beam.

[0008] For a padlock as described above, the strip-shaped hole is arc-shaped.

[0009] For a padlock as described above, the front end of the push shaft is arc-shaped.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: For a padlock of the present utility model, when unlocking, the lock cylinder is rotated by a mechanical key, and the rotation of the lock cylinder pushes the latch pin to move along the strip-shaped hole, thereby driving the push shaft to move upward. The push shaft then pushes the lock tongue to separate from the lock beam, and the lock beam can be unlocked. Compared with the previous method of directly rotating and pushing the lock tongue, this application can make the unlocking smoother, more labor-saving, convenient for users to unlock, and improve the user experience.

[0011] Additional aspects and advantages of the present utility model will be given in part in the following description, become apparent in part from the following description, or be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 7 , in the embodiments of the present utility model, a padlock includes a lock body 1 and a lock beam 2 provided on the lock body 1. It further includes a lock tongue 3 provided in the lock body 1 for restricting the lock beam 2 from bouncing up, so that the lock beam 2 remains in a locked state. An elastic member (not marked in the figure) for keeping the lock tongue 3 tightly locking the lock beam 2 is provided in the lock body 1. In this application, the elastic member is a spring. The lock body 1 is provided with a mechanical lock core 4 for driving the lock tongue 3 to separate from the lock beam 2, so that the lock beam 2 is in an unlocked state. The mechanical lock core 4 includes a lock core housing 40 fixedly provided in the lock body 1 and a lock cylinder 41 provided in the lock core housing 40 and rotatably connected thereto. It further includes a mechanical key (not marked in the figure) cooperating with the lock cylinder 41. Above the lock cylinder 41, there is a push shaft 42 that is slidably matched with the lock body 1 up and down for pushing the lock tongue 3 to separate from the lock beam 2. An axial sleeve 43 for the lower part of the push shaft 42 to penetrate into is formed on the upper part of the lock cylinder 41. An inclined strip-shaped hole 44 is formed on the axial sleeve 43. A pin 45 that is caught in the strip-shaped hole 44 and can move along the strip-shaped hole 44 under the rotation of the push shaft 42 to move the push shaft 42 upward is provided on the push shaft 42. It should be noted that the method of using a spring to make the lock tongue 3 catch the lock beam 2 and the lock beam 2 can bounce up and unlock after separating from the lock tongue 3 is a conventional technique in the art, and will not be elaborated in this application.

[0024] When unlocking, the lock cylinder 41 is rotated by a mechanical key. The lock cylinder 41 rotates to push the pin 45 to move along the strip-shaped hole 44, and then drives the push shaft 42 to move upward. The push shaft 42 then pushes the lock tongue 3 to separate from the lock beam 2, and the lock beam 2 can be unlocked. Compared with the previous method of directly rotating and pushing the lock tongue 3, this application can make the unlocking smoother, more labor-saving, convenient for users to unlock, and improve the user experience.

[0025] As a further solution of this embodiment, the front end of the pin 45 extends out of the strip-shaped hole 44 to form a guiding portion 6. A limiting groove 7 for restricting the rotation of the push shaft 42 is formed in the lock core housing, so that when the axial sleeve 43 acts on the pin 45, the push shaft 42 moves axially, and then pushes the lock tongue 3 to separate from the lock beam 2. After setting the limiting groove 7 to cooperate with the pin 45, the rotation of the push shaft 42 can be restricted. In this way, when the axial sleeve 43 rotates, the push shaft 42 can be pushed to move upward through the strip-shaped hole 44, and the push shaft 42 will not rotate together with the axial sleeve 43.

[0026] As a further solution of this embodiment, the guiding portion 6 is conical. Correspondingly, the cross-section of the limiting groove 7 is the same as that of the guiding portion 6. The guiding portion 6 is set to be conical, and the limiting groove 7 is set to correspond to the shape of the guiding portion 6, so that the operation can be more smooth.

[0027] As a further solution of this embodiment, a slope 8 is formed on the locking tongue 3 for the pushing shaft 42 to push so as to separate the locking tongue 3 from the locking beam 2. By providing the slope 8 on the locking tongue 3, when the pushing shaft 42 moves upward, the slope 8 can be squeezed, so that the locking tongue 3 compresses the spring, and the locking tongue 3 can be separated from the locking beam 2 to achieve unlocking.

[0028] As a further solution of this embodiment, the strip-shaped hole 44 is arc-shaped. The strip-shaped hole 44 being arc-shaped can make the rotation more smooth and thus facilitate unlocking.

[0029] As a further solution of this embodiment, the front end of the pushing shaft 42 is arc-shaped. The front end of the pushing shaft 42 being arc-shaped can reduce the contact area with the locking tongue 3 and the slope 8, thereby reducing the friction force and making the pushing more smooth.

[0030] In addition, in this application, a control panel 9 is provided on the lock body 1. A driving motor 10 electrically connected to the control panel 9 is further provided in the lock body 1. An eccentric rod 11 is provided on the driving shaft of the driving motor 10. A top block 12 cooperating with the eccentric rod 11 is formed on the locking tongue 3. A battery 13 electrically connected to the control panel 9 is further provided in the lock body 1. By inputting a password through the control panel 9, the driving motor 10 can rotate, so that the eccentric rod 11 pushes the top block 12, and thus the locking tongue 3 is separated from the locking beam 2, which is convenient for the user to unlock.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
