Description

Technical Field

[0001] This application relates to the field of fire escape safety window locking technology, and in particular to a mechanical and electrical interlocking structure for a fire escape safety window. Background Technology

[0002] Fire escape staircases are crucial equipment for fire rescue and evacuation in high-rise buildings, and the completeness of their safety facilities directly affects the efficiency of rescue operations and the safety of personnel. The elevator car, as the key component carrying personnel, has safety windows that are essential for ensuring escape in emergencies. A well-designed safety window can provide additional escape routes in emergencies such as fires, increasing the likelihood and success rate of rescue, and playing a significant role in reducing casualties and property damage.

[0003] Currently, the common practice in the industry is to design safety windows that can only be opened from the outside of the car. However, in certain special circumstances, such as when external rescuers cannot arrive in time or when the outside of the car is severely obstructed, people inside the car cannot open the safety windows to escape on their own. This greatly limits their self-rescue ability in emergency situations, may cause them to miss the best escape opportunity, and increase the risk of injury or death. Utility Model Content

[0004] To improve the safety performance of fire escape stairs, this application provides a mechanical and electrical interlocking structure for the safety window of a fire escape stairs.

[0005] The mechanical and electrical interlocking structure for a fire escape safety window provided in this application adopts the following technical solution: A mechanical and electrical interlocking structure for a safety window of a fire escape ladder includes a fixing component, a locking assembly, and an electrical switch. The fixing component is disposed on the outer wall of the movable plate or the car, and the locking assembly is correspondingly disposed on the outer wall of the car or the movable plate. The locking assembly includes a connecting piece, a rotating shaft, and a locking plate. The connecting piece is used to connect to the fire escape ladder. The rotating shaft is rotatably connected to the connecting piece about its own central axis, and the end of the rotating shaft extends into the interior of the car. The locking plate is connected to the end of the rotating shaft. The fixing component has a through-slot, and after the rotating shaft rotates, the locking plate passes through the through-slot. The electrical switch is electrically connected to the control mechanism of the fire escape ladder. When the locking plate leaves the through-slot, the electrical switch is closed, and the fire escape ladder is in a forced stop state.

[0006] Optionally, the locking component is a triangular lock.

[0007] By adopting the above technical solution, based on the installation of a movable plate on the fire ladder for opening and closing the safety window, a triangular lock is used as the locking component. The triangular lock has a simple structure, low cost and high security. The safety window can be locked by rotating the rotating shaft of the triangular lock so that the locking plate passes through the through slot of the fixing part. When it leaves the through slot, it triggers the electrical switch to force the fire ladder to stop, ensuring the safety of use when the safety window is open.

[0008] Optionally, the locking assembly further includes a handle connected to the rotating shaft.

[0009] By adopting the above technical solution and setting up fixing components, locking components and electrical switches, the mechanical and electrical interlocking of the safety window of the fire escape can be realized. The locking plate can lock the movable plate when it enters the slot. When the locking plate leaves the slot, the fire escape is forced to stop to ensure safety. The locking component is equipped with a handle and connected to a rotating shaft, which makes it convenient for the operator to rotate the rotating shaft, thereby controlling the locking plate to enter or leave the slot, realizing the opening and closing operation of the safety window.

[0010] Optionally, the fastener is a plate-like structure.

[0011] By adopting the above technical solution, the fastener is designed as a plate structure, which facilitates installation and the setting of through slots, and is conducive to cooperating with the locking plate to achieve the locking function.

[0012] Optionally, the locking piece is made of a magnetic material, and the fixing member is provided with magnets around the through groove.

[0013] By adopting the above technical solution, the locking plate and the fixing component are fixed by magnetic attraction, which can ensure that the locking plate is stably in the through groove when the safety window is closed, thus enhancing the locking effect.

[0014] Optionally, two magnets are provided, with the two magnets located on the upper and lower sides of the through slot, respectively.

[0015] By adopting the above technical solution, a magnet is set on each of the upper and lower sides of the through slot, which can further enhance the attraction force on the locking plate and make the locking more secure and reliable.

[0016] Optionally, the magnet is detachably connected to the fixing member.

[0017] By adopting the above technical solution, it is convenient to replace, repair and maintain the magnet.

[0018] Optionally, the periphery of the locking plate is covered with sound-absorbing cotton.

[0019] By adopting the above technical solution, the noise generated by the locking plate during operation can be reduced.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a rotating shaft, one end of which extends into the car, a locking plate is connected to the rotating shaft. At the same time, a through groove is opened in the fixing part for the locking plate to rotate into. The locking plate and the through groove cooperate to lock the movable plate. The setting of the rotating shaft allows the locking assembly to be opened both inside and outside the car. At the same time, an electrical switch is used to ensure that the fire ladder is in a stopped state when the movable plate is opened, thereby improving the safety of the fire ladder. 2. By incorporating a handle into the rotating shaft, the ease of operation of the locking assembly is improved; 3. By setting a magnet in the fastener and using magnetic material to make a locking plate, the magnet positions the locking plate when it is inserted into the slot, preventing the locking plate from accidentally rotating into the slot.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a mechanical and electrical interlocking structure for a safety window in a fire escape ladder. The safety window is installed in the car 4 of the fire escape ladder, and a movable plate 41 is connected to the car 4. The movable plate 41 is used to open and close the safety window.

[0029] Example 1 Reference Figures 1 to 3 A mechanical and electrical interlocking structure for a fire escape safety window includes a fixing component 1, a locking assembly 2, and an electrical switch 3.

[0030] In this embodiment, the fixing member 1 is disposed on the outer wall of the car 4, and the locking component 2 is disposed on the movable plate 41. It is understood that in other embodiments, the fixing member 1 may also be disposed on the movable plate 41, and the locking component 2 may be disposed on the outer wall of the car 4 accordingly.

[0031] Electrical switch 3 is installed on movable plate 41 and electrically connected to the control mechanism of fire escape ladder. Thus, the locking assembly 2 and fixing member 1 work together to lock and open the safety window. Simultaneously, electrical switch 3 ensures that the fire escape ladder is stopped when the safety window is open, ensuring the practical safety and convenience of the fire escape ladder safety window.

[0032] Specifically, the fastener 1 is a plate-shaped structure. This type of plate-shaped structure is relatively common and easy to process and install. Alternatively, the structure of the car 4 itself can be used as the fastener 1.

[0033] The locking assembly 2 includes a connecting piece 21, a rotating shaft 22, and a locking plate 23. The connecting piece 21 is used to connect to the car 4 of the fire escape. The rotating shaft 22 is rotatably connected to the connecting piece 21 about its own axis, and the end of the rotating shaft 22 extends into the interior of the car 4. The locking plate 23 is fixedly connected to the end of the rotating shaft 22 away from the connecting piece 21. When the rotating shaft 22 is rotated, the locking plate 23 rotates accordingly.

[0034] The fastener 1 has a through slot 11 for the locking piece 23 to pass through, thereby achieving the locking function. In this embodiment, the fastener 1 is a plate-shaped structure, and the through slot 11 passes through the fastener 1. In other embodiments, if the fastener 1 is a block-shaped structure, the through slot 11 may not pass through the fastener 1, as long as the locking piece 23 can rotate out and into the through slot 11.

[0035] In this embodiment, the locking component 2 is a triangular lock. The rotating shaft 22 can be rotated inside the car 4 by a key, or the rotating shaft 22 can be rotated outside the car 4 by a handle 24, thereby rotating the lock piece 23 out or into the through slot 11.

[0036] The implementation principle of Example 1 is as follows: When the handle 24 is turned to rotate the rotating shaft 22, the locking piece 23 will rotate accordingly and pass into the through slot 11 of the fixing member 1, thereby locking the safety window. When it is necessary to open the safety window, the handle 24 is turned in the opposite direction, the locking piece 23 leaves the through slot 11, and the safety window can be opened. When the locking piece 23 leaves the through slot 11, the electrical switch 3 is turned off, and the fire ladder is in a forced shutdown state.

[0037] Example 2, Reference Figure 4 The difference between this embodiment and embodiment 1 is that the locking assembly 2 also includes a handle 24, which is fixedly connected to the rotating shaft 22, thereby facilitating the rotation of the rotating shaft 22 outside the car 4.

[0038] Example 3 Reference Figure 5 The difference between this embodiment and Embodiment 1 is that the locking piece 23 is made of a magnetic material, such as an iron-nickel alloy. The fixing member 1 has magnets 12 arranged around the through slot 11. In this embodiment, two magnets 12 are provided, located on the upper and lower sides of the through slot 11 respectively. This utilizes the magnetism between the magnets 12 and the locking piece 23 to position the locking piece 23, preventing it from accidentally rotating out of the through slot 11 during the operation of the fire escape ladder, thus further improving the safety performance of the fire escape ladder.

[0039] Furthermore, the fastener 1 has a snap-fit ​​groove 13, in which the magnet 12 is embedded, so that the magnet 12 and the fastener 1 can be detachably connected, so as to facilitate the replacement of the magnet 12.

[0040] Furthermore, the locking plate 23 is surrounded by sound-absorbing cotton 25, which can be made of sponge material, and plays a role in buffering and silencing when the locking plate 23 is engaged with the fixing member 1.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
