Technical Field
[0001] The utility model relates to the technical field of escape locks, in particular to a transmission unlocking mechanism of an electric control system of an electric control escape lock. Background Art
[0002] The basic purpose of the design of standard escape lock products is to provide the escape function of the escape door or the fire prevention and escape function of the fire escape door. All personnel can press the escape lock to open the escape door in an emergency to achieve the purpose of leaving the accident scene in an emergency. However, with the evolution of the times and the demand for upgrading smart products, public areas in some advanced countries have gradually upgraded the escape doors and escape locks that originally only had escape functions to other functions with additional intelligence. Among them, the main function of the escape lock electric lock tongue retraction device is to control the escape lock to automatically open by using external access control or door control system components, without affecting the permanent and necessary "escape" function of the escape lock. The escape door lock is set to control the access restrictions of the door and enable the personnel in the building to escape immediately when a fire occurs. When the escape door lock is equipped with an electric control system transmission unlocking mechanism, an external driving device is usually installed, such as a card reader, a remote control, a contactless infrared sensor switch, a face recognition system or other electric control equipment, or even an automatic door opener is installed. It is usually used when it is inconvenient to use the escape lock pressure rod to push the door. For example, when a hospital pushes a bed through the escape door, if the escape door is equipped with an electric control system transmission unlocking mechanism, an external driving device and an automatic door opener, when the external driving device senses that an object has passed, it triggers the electric control system transmission unlocking mechanism of the escape door lock to drive and open the lock tongue of the escape door lock, and triggers the automatic door opener to open the door, so that medical staff can quickly push the bed through the escape door, or the disabled can enter and exit the escape door by sensing. It can also be used to welcome guests to enter and exit the escape door lock, and the door opens automatically without pressing the escape lock pressure rod.
[0003] On the premise that the basic structure of the original push-type escape lock remains unchanged, a mechanical and electronic control component is added to the outer cover using the empty space under the upper cover to be combined with the external door access or door control system component. When the external door access or door control system component receives the unlocking command, the mechanical and electronic control component added by this patent pushes the upper cover of the escape lock through the mechanical and electronic control component added by this patent, so that the escape lock is pressed down normally and the escape door is opened. All personnel can also press the upper cover of the escape lock normally (without the unlocking command of the external door access or door control system component) to open the escape door.
[0004] This patent application is to add an electric-controlled lock tongue retraction structure and an electronic control element in the empty space of the outer cover (below the upper cover), so that the escape lock has an electric-controlled lock tongue retraction function without affecting or interfering with the original escape lock structure.

[0021] The specific implementation of the present invention will be described in more detail below in conjunction with the schematic diagram. The advantages and features of the present invention will become clearer based on the following description and the scope of the claims. It should be noted that the drawings are all in a very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present invention.
[0022] as follows Figure 1 and 2The electric control system transmission unlocking mechanism of an electric control bolt escape lock shown in the figure comprises a connecting plate 1, the middle position of the connecting plate 1 is connected to the lower end of the transmission middle seat 3 through a first fulcrum 2, the middle position of the transmission middle seat 3 is connected to the moving lower seat 5 through a second fulcrum 4, a pressure rod return torsion spring 9 is installed on the second fulcrum 4, the upper end of the transmission middle seat 3 is connected to the transmission upper seat 7 through a third fulcrum 6, and a pressure rod 8 is installed on the transmission upper seat 7. The transmission between them is realized by the connection of the first fulcrum 2, the second fulcrum 4 and the third fulcrum 6.
[0023] It also includes an electric control device, which includes a transmission member 10, a sliding seat assembly 14, a linear drive assembly 15 and a fixed seat assembly 16. One side of the sliding seat assembly 14 is connected to the linear drive assembly 15, and the other side of the sliding seat assembly 14 is connected to the transmission member 10 through screws. The lower end of the linear drive assembly 15 is fixedly connected to the fixed seat assembly 16 through screws. The transmission member 10 includes a contact plate 101 on the connecting plate and a contact plate 102 under the connecting plate. One end of the connecting plate 1 is arranged between the contact plate 101 on the connecting plate and the contact plate 102 under the connecting plate. Through the setting of the electric control device, the automatic control of the escape lock is realized.
[0024] In addition, the upper contact plate 101 of the connecting plate and the lower contact plate 102 of the connecting plate can be integrated or separated. When the upper contact plate 101 of the connecting plate and the lower contact plate 102 of the connecting plate are two separate contact plates, the upper contact plate 101 of the connecting plate and the lower contact plate 102 of the connecting plate are fixedly connected to the sliding seat assembly 14 by screws. The escape lock is provided with a cover 12, and an upper cover 13 of the electric control device matches the cover 12.
[0025] as follows Figure 1 and 2 The electric control system transmission unlocking mechanism of an electric control bolt escape lock shown in the figure has a Hall switch 11 installed on the fixed seat assembly 16, and a magnet installed on the sliding seat assembly 14. When the linear drive assembly 15 drives the sliding assembly 14 to push the connecting plate 1 of the escape lock, once the magnet on the sliding seat assembly 14 approaches the Hall switch 11 to a set distance, the linear drive assembly 15 will stop moving forward. The stop state is based on the stop time set by the access control device. Once the set stop time is reached, the controller of the linear drive assembly 15 is powered off and has no power. At this time, the escape lock will return the pressure rod to the locked state by the compression force of the pressure rod return torsion spring 9, and also return the linear drive assembly 15 to the position before being driven.
[0026] as follows Figure 3 and Figure 4The electric control system transmission unlocking mechanism of an electric control bolt escape lock shown in the figure is pressed downward by the pressure rod 8, and the pressure rod 8 drives the transmission upper seat 7 to move downward, drives the transmission middle seat 3 through the third fulcrum 6, and connects the transmission base 5 with the second fulcrum 4 of the transmission middle seat 3. Under the action of the force of the pressure rod return torsion spring 9, the transmission connecting plate 1 is connected with the second fulcrum 4 of the transmission middle seat 3 as the movement center to move forward, and finally forms an unlocked state.
[0027] like Figure 6 The electric control system transmission unlocking mechanism of an electric control bolt escape lock shown in the figure, the escape lock is provided with a cover 12, and the electric control device upper cover 13 is matched with the cover 12, forming an aesthetic and protective effect on the equipment.
[0028] Through the detailed description of the preferred embodiments above, it is hoped that the features and spirit of the present invention can be more clearly described, and the scope of the present invention is not limited by the preferred embodiments disclosed above. On the contrary, its purpose is to cover various changes and arrangements with equivalents within the scope of the claims to be applied for by the present invention.
