[0026] To facilitate the understanding of the door lock assembly provided by the embodiments of the present application, the application scenario thereof is first described. The door lock assembly provided by the embodiments of the present application is used on an elevator door to lock the elevator door when it is closed. However, in actual use, the existing door lock has a lock tongue in the extended position after the door is opened, which is easy to scratch the staff. Therefore, it is necessary to manually retract the lock tongue into the door lock, which is not convenient to use. Therefore, the embodiments of the present application provide a door lock assembly to improve the safety of the staff when using the elevator door lock. The specific drawings and embodiments will be described in detail below.
[0027] Reference Figure 1 As shown in the drawings, Figure 1 The application scenario schematic diagram of the door lock assembly provided by the embodiments of the present application is shown. When the door lock assembly is applied to the elevator door, the elevator door includes a first component 2 and a second component 3, and the door lock assembly includes a latch 1 and a door lock 4. In use, the latch 1 and the door lock 4 are correspondingly arranged on the first component 2 and the second component 3. The first component 2 and the second component 3 described above can be different components. For example, the first component 2 and the second component 3 can both be door panels, or one of the first component 2 and the second component 3 is a door panel and the other is a door frame. When it is necessary to release the locking of the elevator door, the latch 1 and the door lock 4 are unlocked, and the first component 2 and the second component 3 can be opened. When it is necessary to lock the elevator door, the latch 1 is inserted into the door lock 4 to lock, thereby locking the elevator door.
[0028] Reference Figure 2 and Figure 3 , Figure 2 The schematic diagram of the latch 1 in the door lock assembly provided by the embodiments of the present application is shown, Figure 3A structural diagram of another angle of the latch 1 is shown. The latch 1 comprises a support base 12 and a lock tongue 11 slidingly assembled with the support base 12. Correspondingly, the door lock 4 is provided with a lock hole matched with the lock tongue 11.
[0029] Referring to Figure 3 and Figure 4 together, Figure 4 A state diagram of the lock tongue 11 sliding out is shown. Figure 4 As shown in the drawings, when the lock tongue 11 slides out, the lock tongue 11 is inserted into the lock hole and locked with the door lock 4, so as to lock the elevator door. As Figure 3 shown, when the lock tongue 11 retracts, the lock tongue 11 slides out of the lock hole, at which time the elevator door can be opened. In addition, the latch 1 further comprises a resilient member 16, one end of which is fixedly connected with the support base 12, the other end of which is fixedly connected with the lock tongue 11, and which can be used to drive the lock tongue 11 to retract into the support base 12. That is, after unlocking, the lock tongue 11 retracts into the support base 12 under the elastic force of the resilient member 16. It should be understood that the above-mentioned retraction of the lock tongue 11 into the support base 12 refers to that the lock tongue 11 can be completely retracted into the support base 12, or that the lock tongue 11 is only partially retracted into the support base 12. However, regardless of the above-mentioned mode, it is necessary to ensure that the lock tongue 11 does not protrude outside the edge of the door panel, so as to avoid the protruding lock tongue 11 scratching the staff, thereby improving the safety of the staff when using the door lock assembly.
[0030] As can be seen from the above description, the door lock assembly provided by the embodiment of the present application can realize the locking of the elevator door through the cooperation of the latch 1 and the door lock 4, and after unlocking, the lock tongue 11 can be rebounded by the resilient member 16 and hidden in the support base 12, thereby avoiding the protruding lock tongue 11 scratching the staff, improving the safety and reducing the security risks.
[0031] Continuing to refer to Figure 2 and Figure 3 , the lock tongue 11 comprises a sliding block 111 slidingly assembled with the support base 12, and a lock tongue head 112 fixedly connected with the sliding block 111, wherein the sliding block 111 is used to cooperate with the support base 12 to realize the sliding therebetween, and the lock tongue head 112 serves as a locking structure matched with the lock hole. In specific use, the sliding of the sliding block 111 drives the sliding of the lock tongue head 112, so as to realize the locking and unlocking with the door lock 4.
[0032] When cooperating with the resilient member 16, the other end of the resilient member 16 is fixedly connected with the sliding block 111. The resilient member 16 can be a tension spring, which is stretched when the lock tongue 11 slides out, and drives the lock tongue head 112 to retract under the elastic force of the resilient member 16 when the lock tongue 11 retracts.
[0033] Exemplarily, the slider 111 is provided with a first spring fixing bolt 14, and the support base 12 is provided with a second spring fixing bolt 15, and the two ends of the elastic member 16 are correspondingly sleeved on the first spring fixing bolt 14 and the second spring fixing bolt 15.
[0034] Of course, it should be understood that the elastic member 16 described above can also be a compression spring or other elastic member 16 that can provide driving force, and is not limited in the embodiment.
[0035] In an implementable scheme, the number of elastic members 16 is two, and the two elastic members 16 are arranged on opposite sides of the slider 111. Figure 2 As shown in FIG. 1, the two elastic members 16 are arranged on the two sides of the slider 111 in the height direction, and one end of each elastic member 16 is fixedly connected with the support base 12, and the other end is fixedly connected with the slider 111. When two elastic members 16 are used to pull the slider 111, the force on the slider 111 can be uniform, so that the locking tongue 11 can be better retracted, and the effect of retraction of the locking tongue is ensured.
[0036] Exemplarily, the support base 12 includes a shell and a mounting plate fixedly connected with the shell; the shell is provided with a sliding groove in sliding cooperation with the slider 111; and the mounting plate is used to limit the slider 111 in the sliding groove. The shell and the mounting plate can be fixedly connected through the connecting member 13 (such as a bolt or a screw), so as to surround a cavity for accommodating the slider 111, so as to limit the slider 111 to slide in the sliding groove, thereby ensuring the stability of the sliding. In addition, when the second spring fixing bolt 15 is provided, the second spring fixing bolt 15 is fixed on the shell.
[0037] In an implementable scheme, the mounting plate is provided with a through hole 17 corresponding to the elastic member 16 and exposing the elastic member 16. Figure 3 As shown in FIG. 1, the mounting plate is provided with a through hole 17, and the elastic member 16 is exposed in the through hole 17. When the elastic member 16 is two, the corresponding through hole 17 is two, and the two through holes 17 can be long strip-shaped through holes 17. When this structure is used, it is convenient to replace the elastic member 16. When the elastic member 16 is damaged, it does not need to disassemble the support base 12, and the maintenance of the bolt 1 is facilitated.
[0038] Continuing to refer to FIG. 1, Figure 2 In a specific implementable scheme, the shell is provided with a mounting hole 18 for exposing the slider 111; and the locking tongue head 112 is fixed to the part of the slider 111 exposed in the mounting hole 18. Thus, the slider 111 and the locking tongue head 112 are fixedly connected. In an implementable scheme, the locking tongue head 112 is fixedly connected with the slider 111 by a bolt.
[0039] In addition, in order to facilitate the use of the door lock assembly, the lock tongue 11 further comprises a toggle wrench which is fixedly connected with the sliding block 111. Exemplarily, the handle 113 can be fixed on the sliding block 111 by welding or by riveting or by other different connecting manners. When it is required to lock the elevator door, the staff can toggle the toggle wrench, thereby driving the sliding block 111 to slide, so as to make the lock tongue head 112 extend and insert into the lock hole. When the toggle wrench is fixed, the toggle wrench is also fixedly connected with the part of the sliding block 111 which is exposed outside the mounting hole 18, so as to facilitate the arrangement of the toggle wrench.
[0040] The embodiment of the present application further provides an elevator door. In the above technical solution, the elevator door can be locked by the cooperation of the bolt 1 and the door lock 4, and after unlocking, the lock tongue 11 can be rebounded by the elastic member, so as to be hidden in the supporting seat 12, thereby avoiding the exposed lock tongue 11 from scratching the staff, improving the safety, and reducing the security risks.
[0041] One or more embodiments of the present specification are intended to cover all such alternatives, modifications and variations falling within the broad scope of the appended claims. Therefore, any omission, modification, equivalent replacement, improvement and the like made in the spirit and principle of one or more embodiments of the present specification should be included in the protection scope of the present disclosure.
