[0003] Currently, the safety window in the elevator car is opened by turning the triangular lock under the safety window with a triangular key inside the elevator car. At the same time as the safety window opens upwards, the switch of the control circuit is disconnected, thus safely stopping the elevator.

[0004] Currently, the safety window requires turning the triangular lock before opening it upwards to disconnect the control circuit. In special circumstances where the safety window is difficult to open, such as debris fallen from the shaft above it or tools forgotten by maintenance personnel, it may be impossible to open the window quickly enough to disconnect the control circuit and ensure the elevator's safe stop.

[0005] Therefore, there is an urgent need to design a safety window-linked elevator safety braking system and a safety braking elevator to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a safety window linkage elevator safety braking system and a safety braking elevator, which can simultaneously brake the elevator when the triangular lock is turned, thereby improving safety.

[0007] To address the aforementioned technical problems, this utility model provides a safety window-linked elevator safety braking system, comprising a safety window, a triangular lock assembly, a latch assembly, and a switch assembly.

[0008] As an improvement to the above solution, the latch assembly further includes a base plate, the assembly housing is disposed above the base plate, and the base plate is disposed above the safety window.

[0009] As an improvement to the above solution, the base plate is provided with an opening, and the baffle is connected to the lever through the opening.

[0010] As an improvement to the above solution, the baffle includes a first baffle, a connecting baffle, and a second baffle connected in sequence. The first baffle is disposed on the top rod, the connecting baffle is disposed in the component box, one end of the second baffle is connected to the connecting baffle, and the other end extends through the opening to the outside of the component box; the connecting baffle is parallel to the bottom plate, and both the first baffle and the second baffle are perpendicular to the bottom plate.

[0011] As an improvement to the above solution, the pin assembly further includes an elastic element sleeved on the top rod, one end of which abuts against the first baffle, and the other end of which abuts against the inner wall of the assembly housing away from the locking tongue.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] like Figure 1 As shown, the present invention provides a safety window linkage elevator safety braking system, which includes a safety window 1, a triangular lock assembly 2, a latch assembly 3, and a switch assembly 4.

[0025] The triangular lock assembly 2 includes a triangular lock 21 and a lever 22. The triangular lock 21 is located at the bottom of the safety window 1, and one end of the lever 22 is connected to the triangular lock 21.

[0026] The latch assembly 3 includes an assembly housing 31, a push rod 32, a locking tongue 33, and a baffle 34. The locking tongue 33 is located at one end of the push rod 32. The push rod 32 passes through the assembly housing 31 and is movably connected to the assembly housing 31. The baffle 34 is located on the push rod 32 and is connected to the other end of the lever 22.

[0027] The switch assembly 4 includes a top plate reinforcing rib 41 and a contact switch 42 disposed above the top plate reinforcing rib 41. The locking tongue 33 is used to insert into the contact switch 42. The triangular lock 21, lever 22, baffle 34, top rod 32, locking tongue 33 and contact switch 42 are linked together to control the working state of the elevator car. Specifically, when the triangular lock 21 is rotated, the lever 22, baffle 34 and top rod 32 are driven in sequence, so that the top rod 32 drives the locking tongue 33 away from the contact switch 42, so that the elevator car is safely stopped.

[0028] It should be noted that when the locking tongue 33 is located inside the contact switch 42, the elevator car power operation circuit is connected, and when the locking tongue 33 leaves the contact switch 42, the elevator car power operation circuit is disconnected. The specific principles of the locking tongue 33 and the contact switch 42 are existing technologies, and their principles will not be described in detail here.

[0029] This utility model discloses a safety window-linked elevator safety braking system. Through the cooperation of the triangular lock 21, lever 22, component box 31, top rod 32, locking tongue 33, and baffle 34, rotating the triangular lock 21 sequentially drives the lever 22, baffle 34, top rod 32, and locking tongue 33, causing the locking tongue 33 to disengage from the contact switch 42. This achieves synchronous rotation of the triangular lock 21 to safely stop the elevator car, solving the defects of traditional structures that require the safety window to be opened before stopping and cannot stop safely in time when encountering obstruction. It can simultaneously brake the elevator when the triangular lock is rotated, improving safety.

[0030] Specifically, the latch assembly 3 further includes a base plate 35, and the assembly box 31 is disposed above the base plate 35, which is located above the safety window 1. The assembly box 31 is fixed above the safety window 1 via the base plate 35, forming a modular unit that facilitates assembly and disassembly within the narrow space of the elevator car ceiling.

[0031] To provide a through-type movement channel for the connection between the baffle 34 and the lever 22, the base plate 35 is provided with an opening 351, through which the baffle 34 is connected to the lever 22. The opening 351 on the base plate 35 ensures that the pushing direction of the lever 22 is consistent with the axis of the push rod 12, reducing lateral forces and improving operational reliability and lifespan.

[0032] Preferably, the baffle 34 includes a first baffle 341, a connecting baffle 342 and a second baffle 343 connected in sequence. The first baffle 341 is disposed on the top rod 32, the connecting baffle 342 is disposed in the component housing 31, one end of the second baffle 343 is connected to the connecting baffle 342, and the other end extends through the opening 351 to the outside of the component housing 31.

[0033] The connecting baffle 342 is parallel to the base plate 35, and the first baffle 341 and the second baffle 343 are both perpendicular to the base plate 35.

[0034] This utility model discloses a safety window-linked elevator safety braking system. By designing the baffle as a three-section bent structure consisting of a first baffle 341, a connecting baffle 342, and a second baffle 343, the connecting baffle 342 is parallel to the bottom plate 35, and the first baffle 341 and the connecting baffle 342 at both ends are perpendicular to the bottom plate 35, forming a rigid frame. When it moves within the opening, it can be self-guided to prevent the top rod 32 from wearing off and enhance stability.

[0035] The latch assembly 3 further includes an elastic element 36 sleeved on the push rod 32. One end of the elastic element 36 abuts against the first baffle 341, and the other end abuts against the inner wall of the assembly housing 31 away from the latch 33. By providing the elastic element 36, when unlocking, the elastic element 36 can automatically push the latch 33 back into the contact switch 42, achieving automatic reset and improving efficiency. Preferably, the opening 351 is rectangular, and the elastic element 36 is a compression spring.

[0036] When the locking tongue 33 is inserted into the contact switch 42, the second baffle 343 abuts against the opening 351, and the elastic member 36 is in its original length state. The rectangular opening 351 and the second baffle 343 form a surface-to-surface limiting relationship. When the locking tongue 33 is inserted into the contact switch 42, the second baffle 343 abuts against the end face of the opening 42, while the elastic member 36 is in its original length state, avoiding fatigue failure due to long-term stress.

[0037] Noise-reducing washers (not shown in the figure) are provided at both ends of the elastic element 36. The noise-reducing washers are made of rubber to absorb noise and energy when the elastic element 36 retracts rapidly.

[0038] The lever 22 includes a first lever 221 and a second lever 222 connected to each other. One end of the first lever 221 is connected to the triangular lock 21, and the other end is connected to one end of the second lever 222.

[0039] When the locking tongue 33 is inserted into the contact switch 42, the second lever 222 is parallel to the second baffle 343. By bending the lever 22 into two sections, the second lever 222 is parallel to the second baffle during unlocking, reducing the initial force required for unlocking and facilitating unlocking.

[0040] Accordingly, this utility model also discloses a safety braking elevator, including an elevator car and the aforementioned safety window linkage elevator safety braking system. The safety window linkage elevator safety braking system is located above the elevator car and is used to control the working state of the elevator car.

[0041] In summary, this utility model's safety window-linked elevator safety braking system, through the cooperation of the triangular lock 21, lever 22, component housing 31, top rod 32, locking tongue 33, and baffle 34, allows the elevator car to be safely stopped synchronously with the rotation of the triangular lock 21. This overcomes the shortcomings of traditional structures that require the safety window to be opened before stopping and cannot stop the elevator in time when encountering obstruction. The system can simultaneously brake the elevator while the triangular lock is being rotated, improving safety. Furthermore, this utility model's safety window-linked elevator safety braking system enhances stability through optimized design of the pin assembly 3 and incorporates an elastic element 36. Upon unlocking, the elastic element 36 automatically pushes the locking tongue 33 back into the contact switch 42, achieving automatic reset and improving efficiency.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
