[0037] As Figures 1 to 10 , this embodiment discloses a door lock, which includes a driving structure for a door lock warning sign, a rear handle 80, a rear baffle assembly 90, and a front handle 100. Among them, the rear handle 80 is rotatably arranged at the rear end of the rear baffle assembly 90, the front handle 100 is rotatably arranged at the front end of the front baffle assembly 50, and the inner core assembly 10 of the lock body is located between the rear baffle assembly 90 and the front baffle assembly 50.

[0038] This embodiment also discloses a driving structure for a door lock warning sign, including:

[0039] The inner core assembly 10 of the lock body;

[0040] The safety lever 20, which can move back and forth inside the inner core assembly 10 of the lock body;

[0041] The support leg 30, which is connected to the safety lever 20 and can move back and forth outside the inner core assembly 10 of the lock body;

[0042] The pushing member 40, which is arranged on the front side of the support leg 30 and is pushed forward by the support leg 30;

[0043] The front baffle assembly 50, which is arranged on the front side of the inner core assembly 10 of the lock body;

[0044] The reminder sign 60 includes a swing arm 61 which is hinged to the front block assembly 50 and is pushed by the pusher 40 to swing, and an unlock reminder sign 62 which is arranged at the swing end of the swing arm 61 .

[0045] The door lock of this embodiment is provided with a support leg 30 connected to the safety rod 20, so that the safety rod 20 can move inside the core assembly 10 of the lock body in the front-to-back direction, and the support leg 30 can move outside the core assembly 10 of the lock body in the front-to-back direction; the support leg 30 is extended outside the core assembly 10 of the lock body without affecting the internal structure of the core assembly 10 of the lock body, and the structure is simpler; when in use, the support leg 30 is driven by the safety rod 20 to push the push member 40 forward, and the push member 40 then pushes the transmission inclined plate 63 to drive the swing arm 61, so that the swing arm 61 swings, thereby driving the unlocking prompt sign 62 to swing to the blocked position, exposing the locked prompt sign 511, and realizing the locked prompt, the structure is simple and reasonable, the movement stroke of the safety rod 20 is short, the operation is safe and reliable, the locking prompt requirement is met, the internal structure of the core assembly 10 of the lock body is not affected, and the core assembly 10 of the lock body can adopt conventional components, thereby reducing the mold opening cost.

[0046] like Figure 4 and Figure 6 As shown, the safety bar 20 of this embodiment is integrally connected with the support leg 30 . The safety bar 20 and the support leg 30 are integrally formed by stamping, and there is no gap at the junction between the two, so the structure has good stability.

[0047] It should be noted that the integral connection between the safety bar 20 and the support leg 30 in this embodiment is only a preferred implementation method. In other embodiments, the connection method between the safety bar 20 and the support leg 30 can also be designed to be welding, riveting, screw fixing, threaded connection, etc., and is not limited to the one-piece molding connection of this embodiment.

[0048] like Figure 5 and Figure 6 As shown, the support leg 30 and the pusher 40 of this embodiment are split structures, the pusher 40 can adopt a round-head pin, and a through hole 513 for the front end of the pusher 40 to pass through is set on the front block housing 51 of the front block assembly 50. In order to adapt to the shape of the round-head pin and guide the round-head pin to prevent the round-head pin from being offset, the through hole 513 can adopt a round hole. Of course, the use of the round-head pin and the round hole in this application is only a preferred embodiment of the pusher 40 and the through hole 513. In other embodiments, a pusher column with a polygonal columnar structure can also be used. Correspondingly, the through hole 513 adopts a polygonal hole adapted thereto, and is not limited to the round-head pin and the round hole in this embodiment.

[0049] Furthermore, the driving structure of this embodiment further includes an elastic member 70 disposed at the rear side of the front shield assembly 50. The elastic member 70 is used to push the pusher 40 backward. The elastic member 70 can be an elastic part such as a spring or a spring piece. When unlocking, the elastic member 70 pushes the pusher 40 towards the leg 30, so that one end of the pusher 40 is always in contact with the leg 30, realizing the automatic reset of the pusher 40. Since the swing arm 61 loses the thrust of the pusher 40, it automatically resets under the action of the return spring 53.

[0050] Of course, setting the leg 30 and the pusher 40 as a split structure is only a preferred embodiment. In other embodiments, the leg 30 and the pusher 40 can also be designed as an integrally connected structure, and the leg 30 directly drives the pusher 40 to move forward or backward.

[0051] Please refer to Figure 5 , the front shield assembly 50 of this embodiment includes a front shield housing 51 and a front cover 52 fixed to the front end of the front shield housing 51. A locking prompt sign 511 is provided at the front end of the front shield housing 51, and the front cover 52 is provided with an opening 521 for exposing the locking prompt sign 511. When unlocking, as Figure 1 shown, the user can directly see the unlocking prompt sign 62 through the opening 521, which has an obvious unlocking prompt function; when locking, as Figure 2 shown, since the unlocking prompt sign 62 swings away from the opening 521, exposing the locking prompt sign 511, what the user directly sees through the opening 521 is the locking prompt sign 511. Therefore, the user can intuitively judge the locking and unlocking states of the door lock, giving the user a good experience.

[0052] In addition, in order to improve the sealing effect of the door lock, some light-transmitting plates such as glass or acrylic plates can be provided at the position of the opening 521, which can not only improve the sealing effect but also does not affect the user's observation of the unlocking prompt sign 62 and the locking prompt sign 511.

[0053] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 10 , the front shield housing 51 of this embodiment is provided with a rotating shaft 512, and the swing arm 61 rotates around the rotating shaft 512. The rotating shaft 512 can be a rivet. The rotating shaft 512 first passes through the first mounting hole 65 of the swing arm 61, and then inserts into the second mounting hole 514 of the front shield housing 51. The swing arm 61 is installed by a rivet, and the swing arm 61 can swing with the rivet as the rotation center, with a simple structure and low installation difficulty.

[0054] Please refer to Figure 8 and Figure 9In this embodiment, a transmission inclined plate 63 inclined forward is provided on the radial inner side of the rotating end of the swing arm 61. When the pusher 40 moves forward, it pushes the transmission inclined plate 63, thereby driving the swing arm 61 to swing. Through the cooperation between the pusher 40 and the transmission inclined plate 63, the linear motion of the pusher 40 is converted into the rotational motion of the swing arm 61 around the rotating shaft 512 as the rotation center, and the structure is ingenious.

[0055] Please refer to Figure 8 and Figure 10 The front block assembly 50 also includes a reset spring 53, which is used to drive the swing arm 61 to reset when there is no external force. The reset spring 53 is a torsion spring. The torsion spring has an eye ring and two spring bars. The eye ring of the torsion spring is sleeved on the outside of the rotating shaft 512. In addition, a spring hanging foot 64 is provided at the rotating end of the swing arm 61. One of the spring bars of the torsion spring is hung on the spring hanging foot 64, and the other spring bar is blocked by the inner wall of the front block housing 51. Under the action of the torsion spring, the swing arm 61 has the function of automatic reset.

[0056] In addition, in other embodiments, the use of the reset spring 53 can be eliminated. Since the door lock is arranged in the front-to-back direction, the automatic reset of the swing arm 61 can be achieved under the action of gravity. Specifically, the mass of the swing end of the swing arm 61 can be increased or the mass of the unlocking prompt sign 62 can be increased. When locking, the push member 40 pushes the swing arm 61 to swing, so that the swing arm 61 swings upward; when unlocking, the push member 40 no longer pushes the swing arm 61, and the swing end of the swing arm 61 swings downward under the action of gravity, thereby achieving automatic reset.

[0057] Please refer to Figure 4 and Figure 5 The door lock further comprises a push button 111 disposed on the rear handle 80 and connected to the rear end of the safety bar 20, a push-pop-up device 112 disposed inside the lock body inner core assembly 10 and connected to the front end of the safety bar 20, and a locking card 1011 disposed inside the lock body inner core assembly 10. The user presses the push button 111 to drive the safety bar 20 to move forward, and the locking card 1011 slides into the locking card slot 2011 under the action of the spring to lock the safety bar 20, thereby achieving locking. To unlock, the user presses the rear handle 80 to push the locking card 1011 to move rightward and leave the locking card slot 2011, and the safety bar 20 is reset under the action of the push-pop-up device 112 to achieve unlocking.

[0058] Please refer to Figures 1 to 4 The lock tongue 11 is driven by the lock body core assembly 10. The lock body core assembly 10 can adopt a conventional existing structure and will not be described in detail below.

[0059] The above has specifically described the preferred embodiments of the present utility model, but the present utility model creation is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent variations or substitutions are all included within the scope defined by the claims of the present utility model creation.
