Description

Technical Field

[0001] The utility model relates to the technical field of safety windows, and more specifically, to an elevator car top safety window device with a triangular lock and a reset device. Background Art

[0002] In the field of elevator safety, the safety window serves as an emergency exit, providing an important escape route for passengers and maintenance personnel in case of an emergency. However, the unlocking device of the elevator safety window and the design of the electrical circuit switch are often independent of each other in the current market. This split design brings many inconveniences and potential safety hazards in practical applications.

[0003] First of all, from the perspective of operation convenience, the split design leads to the complication of the operation process. In case of an emergency, time is particularly precious. However, on-site workers need to operate the unlocking device and the electrical circuit switch separately, which not only increases the operation steps but also increases the possibility of errors. Especially in emergency evacuation or maintenance operations, any delay or error in operation may pose a threat to personnel safety.

[0004] Secondly, the split design is also prone to the risk of accidental disconnection of the safety circuit. Due to the independence between the unlocking device and the electrical switch, if the triggering mechanism of the electrical switch is not precise or stable enough, it is possible to accidentally disconnect the safety circuit without correctly unlocking the safety window, resulting in the elevator entering an abnormal operating state. This situation will not only affect the normal operation of the elevator but also cause unnecessary panic and harm to passengers and maintenance personnel. Therefore, we make improvements and propose an elevator car top safety window device with a triangular lock and a reset device. Summary of the Invention

[0027] In order to enable those skilled in the art to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0028] As recorded in the background art, the designs of common elevator safety window unlocking devices and electrical circuit switches on the market are often independent of each other. This split design brings many inconveniences and potential safety hazards in actual applications.

[0029] To solve this technical problem, this utility model provides an elevator car top safety window device with a triangular lock and a reset device.

[0030] Specifically, please refer to Figures 1-4 , the elevator car top safety window device with a triangular lock and a reset device specifically includes:

[0031] The car top board 1 and the window board assembly 3 arranged on the car top board 1. A lock port 2 is also arranged on the car top board 1. A safety lock structure 4 is arranged between the lock port 2 and the window board assembly 3. The safety lock structure 4 includes a safety lock assembly arranged between the window board assembly 3 and the lock port 2. An electrical switch 404 is arranged on one side of the safety lock assembly. The safety lock assembly is used to cooperate with the lock port 2 to lock the window board assembly 3, and when the safety lock assembly is unlocked, it toggles the electrical switch 404 to disconnect the safety circuit.

[0032] The elevator car top safety window device with a triangular lock and a reset device provided by the present utility model. Through the arranged safety lock structure 4, the safety lock structure 4 sets the safety lock assembly and the electrical switch 404 together, greatly simplifying the operation process of on-site workers, reducing the operation difficulty and error rate. Through optimized design, it is ensured that the electrical switch 404 is triggered only when the safety window is correctly unlocked, thus effectively avoiding the risk of accidental disconnection of the safety circuit and improving the safety of elevator operation.

[0033] In order to enable the personnel in the technical field to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0035] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0036] Example 1, please refer to Figures 1-4 A kind of elevator car top safety window device with a triangular lock and a reset device, including the car top board 1 and the window board assembly 3 arranged on the car top board 1. A lock port 2 is also arranged on the car top board 1. A safety lock structure 4 is arranged between the lock port 2 and the window board assembly 3. The safety lock structure 4 includes a safety lock assembly arranged between the window board assembly 3 and the lock port 2. An electrical switch 404 is arranged on one side of the safety lock assembly. The safety lock assembly is used to cooperate with the lock port 2 to lock the window board assembly 3, and when the safety lock assembly is unlocked, it toggles the electrical switch 404 to disconnect the safety circuit. Through the arranged safety lock structure 4, the safety lock structure 4 sets the safety lock assembly and the electrical switch 404 together, greatly simplifying the operation process of on-site workers, reducing the operation difficulty and error rate. Through optimized design, it is ensured that the electrical switch 404 is triggered only when the safety window is correctly unlocked, thus effectively avoiding the risk of accidental disconnection of the safety circuit and improving the safety of elevator operation.

[0037] Furthermore, the electrical switch 404 is connected to the safety circuit to disconnect the safety circuit when the electrical switch 404 is triggered. The electrical switch 404 is directly connected to the safety circuit to establish a fast and direct response mechanism. When the electrical switch 404 is triggered, the safety circuit can be disconnected in the shortest time. This immediate response is crucial to protecting the lives of passengers and maintenance personnel. It avoids potential safety hazards caused by delays or poor signal transmission, and ensures that the elevator can stop running quickly at the moment of a dangerous situation, thereby minimizing potential risks and injuries. In addition, this direct connection method reduces intermediate links, reduces the possibility of failures, and improves the reliability and stability of the entire system.

[0038] Further, such as Figures 1-2 As shown, a car top window 101 is also provided on the car top board 1, and the window panel assembly 3 is connected to the car top board 1 through a hinge, and the position of the window panel assembly 3 covers the car top window 101. The window panel assembly 3 is used to protect the car top window 101, and is hinged so that the window panel assembly 3 can be opened. The window panel assembly 3 is connected to the car top board 1 through a hinge. This flexible opening and closing design is not only convenient for daily maintenance and inspection work, but also can be opened in an emergency to gain precious time for rescue operations. At the same time, the window panel assembly 3 can tightly cover the car top window 101 under normal conditions, effectively preventing external impurities such as dust and rain from entering the car, thereby ensuring the cleanliness and dryness of the internal environment of the car.

[0039] Embodiment 2 further optimizes the elevator car top safety window device with the triangular lock and reset device provided in Embodiment 1. Specifically, Figures 1-3 As shown, the safety lock assembly includes a triangular lock body 401 arranged on the window panel assembly 3, and the outer surface of the triangular lock body 401 is connected to a first locking arm 402, and one side of the first locking arm 402 is connected to a second locking arm 403, and the second locking arm 403 is plugged into the outer surface of the lock port 2. The plugging of the second locking arm 403 and the lock port 2 can achieve locking of the window panel assembly 3, and the first locking arm 402 is rotated to separate the second locking arm 403 from the lock port 2 to unlock the door. This structural design that achieves locking by plugging has excellent stability and reliability. The plugging method makes the connection between the second locking arm 403 and the lock port 2 tight and firm, and can withstand large external force impact, and effectively prevent unlocking caused by accidental vibration or external force interference. The operation method of rotating the first locking arm 402 to achieve unlocking is simple and intuitive, easy to understand and master, and can be quickly operated by both professionally trained maintenance personnel and passengers in emergency situations. This simple and direct unlocking method can save precious time at critical moments and improve the efficiency of rescue and emergency handling.

[0040] Further, such as Figure 2 and Figure 3As shown, one end of the first locking arm 402 close to the electrical switch 404 is inclined so as to toggle the electrical switch 404 when the first locking arm 402 rotates, thereby triggering the electrical switch 404. The inclined setting of the first locking arm 402 greatly optimizes its interaction mechanism with the electrical switch 404. The inclined surface can ensure that when the first locking arm 402 rotates, it contacts the electrical switch 404 in a more smooth and stable manner, reducing the jamming or unstable triggering that may occur due to improper collision angles. This smooth toggling action improves the accuracy and reliability of triggering the electrical switch 404, reduces the risk of mis-triggering or non-triggering due to poor contact or insufficient toggling, and at the same time, the inclined setting can also reduce the impact and wear on the electrical switch 404, extend the service life of the electrical switch 404, reduce the frequency of maintenance and replacement, thereby saving maintenance costs.

[0041] Furthermore, as Figure 4 shown, a reset part is provided between the window panel assembly 3 and the first locking arm 402. The reset part is used for resetting the first locking arm 402. Introducing the reset part enables the first locking arm 402 to automatically return to the initial position after completing the operation without manual intervention, which not only reduces the workload of workers but also reduces the safety hazards caused by forgetting to reset, ensuring that it can accurately return to the initial state after each use and preparing for the next normal operation.

[0042] Furthermore, as Figure 2 and Figure 3 shown, the reset part includes a fixed seat 405 fixedly installed on the window panel assembly 3. A plurality of reset springs 406 are connected between the fixed seat 405 and the first locking arm 402. After the first locking arm 402 completes the operation, the reset springs 406 can pull the first locking arm 402 to automatically return to the initial position without manual intervention, which not only reduces the workload of workers but also reduces the safety hazards caused by forgetting to reset.

[0043] Embodiment 3 further optimizes the elevator car top safety window device with a triangular lock and a reset device provided in Embodiment 1 or 2. Specifically, as Figure 2 shown, the window panel assembly 3 is composed of two window panel bodies 301. The two window panel bodies 301 are connected by a hinge, and one of the window panel bodies 301 is also connected to the car top plate 1 by a hinge. By using two window panel bodies 301 and connecting them by a hinge, the space occupied when the window panel assembly 3 opens and closes is reduced. In daily maintenance and emergency situations, the smaller opening and closing space can avoid collisions and interferences with other equipment or structures, ensuring the smoothness and safety of the operation.

[0044] Furthermore, as Figure 4As shown, the safety lock structure 4 is provided on the window panel main body 301 near the lock opening 2, and the triangular lock body 401 penetrates through the window panel main body 301.

[0045] Furthermore, the safety lock assembly further includes a triangular key. The triangular key is used to operate the triangular lock body 401. The triangular lock body 401 can be operated from the inside of the car using the triangular key, or the first lock arm 402 can be directly rotated by hand from the top of the car roof 1.
