[0029] See also Figures 1 to 4 In the specific embodiment shown, the utility model discloses a railing door lock structure, comprising: a first railing 10 and a second railing 20 arranged side by side, the first railing 10 is movably connected with a lock plate 30, the second railing 20 is connected with a lock assembly 40, the lock assembly 40 is provided with a lock body 42 and a lock tongue 43, the lock tongue 43 is transmission-connected to the lock body 42, the lock plate 30 is provided with a notch 31 corresponding to the lock tongue 43, and the lock body 42 is rotated to allow the lock tongue 43 to be inserted into or moved out of the notch 31.
[0030] Specifically, when the lock body 42 is rotated so that the lock tongue 43 is inserted into the notch 31, a locked state is formed, and the lock plate 30 cannot be rotated; when the lock body 42 is rotated so that the lock tongue 43 is moved out of the notch 31, an unlocked state is formed, and the lock plate 30 can be rotated. The railing door lock is easy to open and close, and has the characteristics of high strength and durability, which well solves the pain points of actual use.
[0031] In one embodiment, the lock assembly 40 includes a lock seat 41, which is connected to the second railing 20. A rotating shaft 44, a spring 45, a sliding column 46, the lock body 42 and the lock tongue 43 are provided inside the lock seat 41. A portion of the lock body 42 and the lock tongue 43 extend out of the lock seat 41. The rotating shaft 44 is transversely installed on the lock seat 41. One end of the lock tongue 43 is rotatably connected to the rotating shaft 44, and the other end abuts against the spring 45. The spring 45 is installed on the lock seat 41 at one end away from the lock tongue 43. One end of the sliding column 46 is connected to the lock tongue 43, and the other end is slidably connected to the lock body 42. The lock body 42 is rotatably connected to the lock seat 41; the lock body 42 is rotated to move the sliding column 46 to drive the lock tongue 43 to insert into or move out of the notch 31.
[0032] Specifically, the rotating shaft 44, the spring 45 and the slide post 46 are located on the back of the lock tongue 43, the upper end of the lock tongue 43 is sleeved on both sides of the rotating shaft 44, the slide post 46 is fixed to the lower end of the lock tongue 43, and the spring 45 is located on the side of the slide post 46. When the lock body 42 is rotated to push the slide post 46 (i.e. the lock body 42 rotates counterclockwise), the slide post 46 is driven to move toward the end away from the notch 31, so as to drive the lock tongue 43 to move toward the end away from the notch 31, that is, the lock tongue 43 moves out of the notch 31, and the spring 45 is in a compressed state at this time; when the lock body 42 is rotated to release the slide post 46 (i.e. the lock body 42 rotates clockwise), under the action of the spring 45, the slide post 46 is pushed to move toward one end of the notch 31, so as to drive the lock tongue 43 to move toward one end of the notch 31, that is, the lock tongue 43 is inserted into the notch 31.
[0033] Preferably, there are two springs 45 , which are respectively located on both sides of the slide post 46 to ensure sufficient elastic force so that the locking tongue 43 can be inserted into the notch 31 to form a locked state.
[0034] In one embodiment, the lock body 42 is provided with an arc-shaped locking plate 421, one side of the locking plate 421 is a short end, and the other side is a high end, the short end is close to the sliding column 46, and the high end is far away from the sliding column 46; when the locking tongue 43 is inserted into the notch 31, the short end abuts against the sliding column 46, and when the locking tongue 43 moves out of the notch 31, the high end abuts against the sliding column 46.
[0035] Specifically, the back of the lock body 42 is provided with an arc-shaped locking piece 421. When the lock body 42 is rotated counterclockwise, the arc-shaped locking piece 421 rotates from the high end to the low end, so that the locking piece 421 squeezes and pushes the sliding column 46, so that the spring 45 is in a compressed state, and the lock tongue 43 moves out of the notch 31; when the lock body 42 is rotated clockwise, the arc-shaped locking piece 421 rotates from the low end to the high end, so that the locking piece 421 releases the push on the sliding column 46, and under the action of the spring 45, the lock tongue 43 is inserted into the notch 31. The effect of this design can ensure that the lock body 42 can correctly control the position of the locking piece 421 when the lock tongue 43 is inserted into or moved out of the notch 31, that is, through the contact between the high and low ends of the locking piece 421 and the sliding column 46, it can be ensured that the lock body 42 is in the correct position when the lock tongue 43 is inserted into the notch 31, thereby ensuring the safety and reliability of the door lock, and effectively preventing unauthorized personnel from opening the door lock by improper means, thereby improving the safety of the door lock.
[0036] In one embodiment, a wedge-shaped protrusion 431 is disposed on a side of the locking tongue 43 facing the notch 31 . The wedge-shaped protrusion 431 extends out of the locking seat 41 and matches with the notch 31 .
[0037] Specifically, through the design of the wedge-shaped protrusion 431, when the lock tongue 43 is inserted into the notch 31, the wedge-shaped protrusion 431 can guide the lock tongue 43 to the position of the notch 31 and provide additional support and stability to ensure that the lock tongue 43 is firmly inserted into the notch 31, thereby enhancing the safety and reliability of the door lock.
[0038] In one embodiment, a baffle 411 is further extended outward from the lock seat 41 , and the lock plate 30 is located between the lock seat 41 and the baffle 411 .
[0039] Specifically, the baffle 411 supports the lock plate 30 so that the lock tongue 43 can be accurately inserted into the notch 31. In addition, the baffle 411 also blocks the wedge-shaped protrusion 431, thereby preventing the wedge-shaped protrusion 431 from being pushed by an external force, thereby improving safety.
[0040] In one embodiment, the first railing 10 is installed with a base 11 , the locking plate 30 is movably connected to the base 11 , and the base 11 has the same structure as the locking seat 41 .
[0041] Specifically, the base 11 is fixed to the first railing 10 by screws. The base 11, as the installation base of the lock plate 30, can provide a stable support to ensure that the lock plate 30 will not shake or loosen during use, thereby enhancing the stability and reliability of the door lock. In addition, the base 11 and the lock base 41 have the same structure, which means that they can use the same manufacturing process and materials, making production and installation easier and reducing costs and complexity.
[0042] In one embodiment, a fixed shaft 12 is connected to the base 11 , and the locking plate 30 is rotatably connected to the fixed shaft 12 .
[0043] Specifically, the fixed shaft 12 is fixed to the base 11 by welding, and the lock plate 30 is rotatably connected through the fixed shaft 12, which means that the lock plate 30 can rotate around the fixed shaft 12 to facilitate the opening and closing operations of the lock plate 30. In addition, the fixed shaft 12 provides a stable connection point, so that the lock plate 30 can rotate around the axis, and because the lock plate 30 often needs to be opened and closed, this design can ensure the durability and stability of the connection point and extend the service life of the door lock. In addition, by using the fixed shaft 12, the connection method between the lock plate 30 and the base 11 can be simplified, the manufacturing cost can be reduced, and the reliability and stability of the door lock can be improved.
[0044] In one embodiment, the notch 31 is disposed transversely, and the notch 31 is horizontally slidably connected to the fixed shaft 12 .
[0045] Specifically, the notch 31 is horizontally slidably connected to the fixed shaft 12, allowing the lock plate 30 to be adjusted in position within a certain range. This adjustment function can be used to calibrate the position of the lock plate 30 to ensure the fit between the lock plate 30 and the wedge-shaped protrusion 431, thereby improving the performance and reliability of the door lock.
[0046] In one embodiment, a handle 32 is further provided at one end of the locking plate 30 away from the base 11 .
[0047] Specifically, the handle 32 is fixed to the lock plate 30 by welding. The handle 32 provides a convenient handhold, so that the lock plate 30 can be easily operated. When the door lock needs to be opened or closed, the handle 32 can be directly used without directly touching the lock plate, thereby improving the convenience and comfort of using the door lock. In addition, the handle 32 can help the user to correctly operate the lock plate 30 and reduce the possibility of misoperation. Especially at night or in dim light, the handle 32 can help the user accurately locate and operate the lock plate 30, thereby improving the safety of the door lock. In addition, the handle 32 not only has a practical function, but also can be used as one of the decorative elements of the door lock. A well-designed handle 32 can increase the overall aesthetics of the door lock.
[0048] In one embodiment, the lock body 42 is a triangular lock, which can be opened or closed by rotating the triangular lock with a triangular key; when the triangular lock is closed, the lock tongue 43 is inserted into the notch 31, and when the triangular lock is opened, the lock tongue 43 moves out of the notch 31. The triangular lock has multiple locking points, which can provide higher security than the traditional single locking point design. In addition, since the triangular lock has multiple locking points, they can better disperse pressure and maintain a more stable state. In addition, since the triangular lock has multiple locking points, when one of the locking points is pried by external force, the other locking points remain locked to prevent the door from being easily pried open.
[0049] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
