Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a novel car roof safety window structure. Background Technology

[0002] Installing safety windows on the top of elevator cars is an important measure to ensure the safety of elevator maintenance personnel and passengers. Traditional safety windows have problems such as inconvenient hook operation and insufficient locking force during opening and closing, which may lead to accidental opening or improper closing during use. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a novel car roof safety window structure.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A novel car roof safety window structure includes a car roof base plate, a safety window base plate, a lock plate, a lock cylinder base plate, and a safety switch assembly. A safety window is located in the middle of the car roof base plate. A safety window base plate is installed at the safety window. A hinge mounting base is glued to one side of the safety window on the car roof base plate. Two hinges are mounted on the hinge mounting base, and the other side of the hinges is connected to the safety window base plate. Longitudinal reinforcing ribs for the safety window are glued to both sides of the safety window on the car roof base plate. Transverse reinforcing ribs for the safety window are glued to both ends of the safety window on the car roof base plate. The lock plate is installed on the longitudinal reinforcing ribs. A lock cylinder is installed on the lock cylinder base plate. The lock cylinder base plate is installed at the lock hole of the safety window base plate. A lock hook is installed on the lock cylinder. A tension spring is installed above the lock cylinder, with its two ends connected to the lock cylinder base plate and the lock hook, respectively. The safety switch assembly is installed on the safety window base plate and the lock hook.

[0006] A pad is provided between the safety switch assembly and the bottom plate of the safety window.

[0007] The car roof bottom plate is reinforced with car roof bottom plate reinforcing ribs at both ends.

[0008] The hinge mounting base has hinge reinforcing ribs welded to the hinge mounting position.

[0009] The lock cylinder base plate is C-shaped, with a round hole at the top. The lock hook consists of a vertical plate in the middle and horizontal plates at both ends facing the sides. The vertical plate has a round hole, and the two ends of the tension spring are connected to the round holes on the lock cylinder base plate and the vertical plate, respectively.

[0010] The beneficial effects of this utility model are: the extension spring provides continuous tension to the locking hook during the closing and opening process, thereby enhancing the locking force of the locking hook, preventing the safety window from being opened accidentally, and improving the safety and reliability of the safety window. The reverse tension of the extension spring makes the locking hook open and close more smoothly, reducing the operating force, making it easy to operate, with a simple overall structure, less prone to failure, and with a long service life.

[0014] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0016] A novel car roof safety window structure includes a car roof base plate 1, a safety window base plate 4, a lock plate 9, a lock cylinder base plate 10, and a safety switch assembly 14. A safety window is provided in the middle of the car roof base plate 1, and the safety window base plate 4 is installed at the safety window. A hinge mounting base 6 is glued to one side of the safety window on the car roof base plate 1. Two hinges 8 are installed on the hinge mounting base 6, and the other side of the hinges 8 is connected to the safety window base plate 4. Longitudinal reinforcing ribs 3 are glued to both sides of the safety window on the car roof base plate 1, and transverse reinforcing ribs 5 are glued to both ends of the safety window on the car roof base plate 1. The lock plate 9 is installed on... A lock cylinder 12 is installed on the longitudinal reinforcing rib 3 of the safety window and on the lock cylinder base plate 10. The lock cylinder base plate 10 is installed at the lock hole of the safety window base plate 4. A lock hook 11 is installed on the lock cylinder 12. A tension spring 13 is set above the lock cylinder 12. The two ends of the tension spring 13 are respectively connected to the lock cylinder base plate 10 and the lock hook 11. The safety switch assembly 14 is installed on the safety window base plate 4 and the lock hook 11. The safety switch assembly 14 is a contact switch. After the safety window is locked in place, the contact switch is in contact, the safety circuit is open, and the elevator can operate normally. The safety switch assembly 14 adopts the HY06077 elevator door lock contact switch.

[0017] A pad 15 is provided between the safety switch assembly 14 and the safety window bottom plate 4.

[0018] The car roof bottom plate 1 is bonded with car roof bottom plate reinforcing ribs 2 at both ends.

[0019] The hinge mounting base 6 has a hinge reinforcing rib 7 welded to the mounting position of the hinge 8.

[0020] The lock cylinder base plate 10 is C-shaped, and a round hole is provided at the top of the lock cylinder base plate 10. The lock hook 11 is composed of a vertical plate in the middle and horizontal plates at both ends of the vertical plate facing the sides. A round hole is provided on the vertical plate. The two ends of the tension spring 13 are respectively connected to the round holes on the lock cylinder base plate 10 and the vertical plate.

[0021] When this utility model is in operation, one end of the tension spring 13 is connected to the locking base plate 4, and the other end is connected to the locking hook 11. When the safety window is closed, the tension spring 13 provides tension to help the locking hook 11 lock automatically, ensuring that the safety window is closed tightly.

[0022] When the safety window is opened, the tension spring 13 provides a reverse pulling force to help the locking hook 11 disengage smoothly and keep the locking hook 11 in the open state for easy operation.
