[0042] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0043] like Figure 1-9 As shown, the following embodiment discloses a door buckle hand lock with an emergency device.

[0044] It includes a lock tongue 200, an unlocking component for driving the lock tongue 200 to move, and a padlock 400 for locking the unlocking component; and also includes an emergency device, which can drive the lock tongue 200 for emergency unlocking.

[0045] The above is the basic solution of this embodiment.

[0046] When unlocking, the unlocking component is operated, and the unlocking component drives the lock tongue 200 to move to unlock; when locking, the unlocking component is reset, the lock tongue 200 is in the locked position, and then the unlocking component is locked by the locking member, and the user cannot operate the unlocking component, thereby being unable to unlock the lock tongue 200;

[0047] When the locking member fails, the unlocking component cannot be released. At this time, the user unlocks the emergency device, and the emergency device can also drive the lock tongue 200 to move and unlock.

[0048] Specific reference Figure 1 and Figure 2 As shown, in this embodiment, the door is used as a carrier, the lock is arranged on the fixed door 120, and the lock tongue 200 extends toward the movable door 110 to lock the movable door 110;

[0049] Meanwhile, the emergency device is arranged on the fixed door 120, and is located on the side of the locking tongue 200;

[0050] The specific configuration of the emergency device in this embodiment is as follows: the emergency device is a lock core 300 , and the lock core 300 is provided with a driving portion that can drive the lock tongue 200 .

[0051] Specifically, the lock core 300 is disposed on the housing 500 or the door, and the lock core 300 is unlocked with the housing 500 or the door by a key; when the lock core 300 rotates, the driving part rotates accordingly, driving the lock tongue 200 to move.

[0052] In this embodiment, the lock core 300 drives the lock tongue 200 in the following manner: the driving portion is a driving tongue 321 extending from the lock core 300 , and the lock tongue 200 is provided with a driving groove 201 cooperating with the driving tongue 321 .

[0053] Specific reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the moving direction of the lock tongue 200 is set to horizontal movement, the driving groove 201 is set on the upper end surface of the lock tongue 200, and the driving tongue 321 is inserted into the driving groove 201;

[0054] When the mechanical lock is unlocked by a key, the lock core 300 rotates, and the driving tongue 321 rotates with the lock core 300, generating a displacement in the horizontal direction, thereby driving the lock tongue 200 to move horizontally.

[0055] Preferably, in the present embodiment, the two groove walls of the driving groove 201 in the horizontal direction are arranged as inclined surfaces. When unlocking, when the driving tongue 321 rotates to the extreme position, that is, the outer end surface of the driving tongue 321 makes surface contact with the inclined groove wall. At this time, the direction of the force between the driving tongue 321 and the unlocking groove 202 is perpendicular to the inclined surface, and the reaction force is also perpendicular to the same inclined surface, that is, the force is balanced. At the same time, in the present embodiment, a stop portion is also provided on the back of the outer shell 500 to stop the driving tongue 321.

[0056] In this embodiment, the locking method of the unlocking component of the padlock 400 is specifically configured as follows: it also includes a shell 500, and the shell 500 is provided with a lock tongue cavity and an unlocking cavity a;

[0057] The lock tongue 200 is located in the lock tongue cavity, and an elastic component 600 is provided in the lock tongue cavity to push the head of the lock tongue 200 out of the lock tongue cavity;

[0058] The unlocking component is located in the unlocking cavity a, and extends into the lock tongue cavity to drive the lock tongue 200;

[0059] The padlock 400 is suspended in the unlocking cavity a to limit the unlocking space, so that a human hand cannot reach into the unlocking cavity a to operate the unlocking component.

[0060] Specific reference Figure 2 As shown, in this embodiment, the unlocking component is a pull plate 700, and the first side of the pull plate 700 is hinged on the housing 500, and the second side is pulled by hand;

[0061] The padlock 400 is suspended in the unlocking cavity a and is located on the side of the second side of the pull plate 700, occupying the space on the second side of the pull plate 700;

[0062] When the padlock 400 is located in the unlocking cavity a, a person's hand cannot reach into the unlocking cavity a to pull the handle, so the lock tongue 200 cannot be unlocked by the unlocking component, thereby achieving the purpose of locking.

[0063] In the natural state, the locking tongue 200 is held by the elastic component 600 and is always in a locked state.

[0064] Preferably, in this embodiment, the elastic component 600 is preferably a spring.

[0065] In this embodiment, the unlocking component is provided with an unlocking rod 710 , and the locking tongue 200 is provided with an unlocking slot 202 capable of accommodating the unlocking rod 710 to extend therein.

[0066] Specific reference Figure 3-Figure 5As shown, in this embodiment, the unlocking slot 202 is arranged in the middle of the lock tongue 200, and the driving direction of the unlocking rod 710 in the unlocking slot 202 is also horizontal; when the user operates the handle and turns the handle, the unlocking rod 710 also rotates accordingly, generating a displacement in the horizontal direction to drive the lock tongue 200.

[0067] In this embodiment, the function of the emergency device is to drive the lock tongue 200 to move when the unlocking component cannot drive the lock tongue 200 to move; therefore, when the unlocking component is locked, the lock tongue 200 is still in a state where it can be driven, so that it can be unlocked by the emergency device.

[0068] Therefore, in this embodiment, the movable range of the unlocking rod 710 in the unlocking slot 202 is greater than the movable range of the driving part in the driving slot 201 .

[0069] Specific reference Figure 4 As shown, when the lock tongue 200 is in the locked position, the end of the unlocking rod 710 is located inside the lock tongue 200, and there is a certain space between the end of the unlocking rod 710 and the front end of the unlocking groove 202. At this time, if the handle is not used to unlock, the unlocking rod 710 does not move, and the lock tongue 200 can still be retreated into the lock tongue cavity under the action of the emergency device.

[0070] In this embodiment, the arrangement of the padlock 400 is as follows: a padlock portion is movably provided on the lock tongue 200 toward the unlocking slot 202, and the padlock 400 is suspended on the padlock portion;

[0071] The padlock portion can move relative to the lock tongue 200 .

[0072] In an emergency state, the padlock 400 is suspended in the padlock part, and the padlock part and the padlock 400 cannot move together, so that the handle cannot be operated; and due to the drive of the emergency component, the lock tongue 200 moves in the horizontal direction and retreats into the lock tongue cavity. Therefore, a relative movement is required between the lock tongue 200 and the padlock part to enable the lock tongue 200 to move when the padlock 400 is stationary.

[0073] Specifically, in this embodiment, the padlocking part is a suspension beam 810, and the suspension beam 810 is provided with a lock hole 811 capable of accommodating the passage of the hung lock bent arm 410.

[0074] In this embodiment, in order to prevent the padlocking part from moving along with the lock tongue 200, a limiting part is provided in the unlocking cavity a to limit the horizontal position of the padlocking part.

[0075] Reference Figure 8As shown, specifically, a partition 510 is provided in the housing 500 to divide its inner cavity into a lock tongue cavity and an unlocking cavity a, and the housing 500 on one side of the unlocking cavity a is provided with a hollow portion capable of accommodating a human hand to be inserted;

[0076] The limiting part extends on the partition 510 and faces the unlocking chamber a, specifically, the limiting ears 511 located on the upper and lower sides of the padlock part, and an avoidance gap 511.1 is arranged between the two limiting ears 511, and the padlock part can pass through the avoidance gap 511.1 and move horizontally; when the padlock 400 is hung on the padlock part, the bent arm 410 on the padlock 400 cannot pass through the avoidance gap 511.1, thereby limiting the padlock part.

[0077] In this embodiment, the specific implementation of the movable connection between the padlock part and the lock tongue 200 is as follows: a slide groove is provided on the lock tongue 200 to connect with the unlocking groove 202, a slider 800 is provided in the slide groove, and the padlock part is extended on the slider 800;

[0078] The bottom of the slide groove is provided with a limiting groove 203 capable of accommodating the padlock part to extend and slide.

[0079] Specific reference Figure 7 As shown, when the handle is used to unlock, the padlock 400 is unlocked and removed from the padlock part. At this time, the space in the unlocking groove 202 can accommodate a hand to reach in and operate the handle; the second end of the handle is pulled to rotate, and the unlocking rod 710 is driven to rotate during the rotation of the handle. The unlocking rod 710 drives the lock tongue 200 to retract the lock tongue 200 into the lock tongue cavity; at the same time, the padlock part moves with the lock tongue 200 to the avoidance gap 511.1 between the two limit ears 511, refer to Fig. 9 As shown;

[0080] When the padlock 400 cannot be unlocked, and the handle cannot be operated to drive the lock tongue 200, the lock core 300 is unlocked, and the driving tongue 321 on the lock core 300 drives the driving groove 201, so that the lock tongue 200 is locked back into the lock tongue cavity; at the same time, the padlock part cannot move due to the limit of the padlock 400, so that the sliding block cannot move either. Figure 5 shown.
