[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0033] In this embodiment, the directional terms such as "inner" and "outer" are used for ease of explanation and are not intended to limit the scope of the application. The inner surface refers to the side of the aluminum alloy screen door that is installed on the interior side, and the outer surface refers to the side of the aluminum alloy screen door that is installed on the exterior side.
[0034] See Figs. 1 to 4 As shown, a strip lock for a screen door is used to install on an aluminum alloy screen door, including a lock shell 1, an inner sliding member 2, an outer sliding member 3, and a latch component 4. In this embodiment, grooves are provided on both the inner and outer surfaces of the lock shell, which is a common practice in the prior art and therefore not described in detail. During assembly, the inner sliding member is placed on the inner surface of the lock shell, and the outer sliding member is placed on the outer surface of the lock shell. Furthermore, the outer side of the inner sliding member is provided with two first forks 5, and the inner side of the outer sliding member is provided with two second forks 6. Both the first and second forks are plastic or metal structures. During assembly, the inner and outer sliding parts are combined, and the first and second shift forks are combined to form two complete shift fork bodies; the locking tongue component is located between the inner and outer sliding parts, and between the two shift fork bodies; through the above structure, the first and second shift forks can be raised and lowered independently, and they cooperate with the locking tongue component to make the inner and outer sliding parts slide synchronously when the inner or outer sliding parts slide, thereby realizing the locking or unlocking operation. The inner or outer sliding parts slide and drive the locking tongue component to move horizontally through the shift fork bodies.
[0035] With the above structure, sliding locking or unlocking operations can be achieved on the inside of the aluminum alloy screen door, and also on the outside of the aluminum alloy screen door.
[0036] In this embodiment, the bottom surfaces of the inner and outer sliding parts are respectively fitted with locking fasteners 7; a lock body 8 is provided at the bottom of the locking fasteners; both the inner and outer surfaces of the lock shell are provided with keyhole positions 9 connected to the lock body; the lock body achieves synchronous locking or unlocking of the inner and outer sliding parts through the locking fasteners. This structure improves safety and reliability; after locking, the lock can be engaged through the lock body, and when external or internal opening is required, the lock body must be unlocked before the inner or outer sliding parts can be moved, thus enhancing safety.
[0037] In practical applications, both the first and second shift forks are provided with clearance areas 10; during assembly, the first and second shift forks are respectively located within their clearance areas. That is, through the above structure, effective combination operations can be achieved. Furthermore, in this embodiment, the clearance areas are located at the edges of the first and second shift forks, and the clearance areas of the first and second shift forks are staggered. This ensures the effectiveness and reliability of the combination.
[0038] In this embodiment, the locking tongue component 4 includes a screw 41 and a locking tongue 42 fixed to the end of the screw; wherein the screw is located between two shift forks. The width of the two shift forks matches the diameter of the screw. This structure ensures the smoothness and reliability of the locking tongue component's translational operation under the action of the two shift forks, and also prevents the locking tongue from loosening or falling off.
[0039] In this embodiment, the bottom surfaces of the inner and outer sliding parts are provided with T-shaped slots 11; and the top surface of the locking element is provided with U-shaped latching lugs 12. During assembly, the U-shaped latching lugs of the locking element are engaged in the T-shaped slots for positioning. This structure improves the ease and reliability of connection between the locking element and the inner and outer sliding parts, facilitating disassembly, assembly, and maintenance.
[0040] This utility model has positive effects: The structure of this utility model is reasonably designed, including an inner sliding member, an outer sliding member, and a locking tongue component. The first fork on the inner sliding member and the second fork on the outer sliding member form a complete fork body, and the locking tongue component is located between the fork bodies. Thus, when the inner or outer sliding member slides, the locking tongue component can be moved by the fork body to complete the locking or unlocking operation. That is, it can realize not only the inner sliding control operation but also the outer sliding control operation, which improves its ease of use and has strong applicability.
[0041] Furthermore, the bottom surfaces of the inner and outer sliding parts are respectively fitted with locking fasteners; the bottom of the locking fasteners is equipped with a lock body; both the inner and outer surfaces of the lock case are equipped with keyholes that connect to the lock body. After sliding, the lock body can be used to lock and position the lock, and the corresponding keyholes can be used to unlock the lock from the inside or outside, improving security and ease of use.
[0042] A screen door, including the aforementioned bar lock.
[0043] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
