Description

A car door lock follow-up switch structure

technical field

The utility model relates to the field of car door locks, in particular to a car door lock follow-up switch structure.

Background technique

Car door locks are the most basic safety items for elevators, including mechanical door locks and electric door locks. The mechanical ones are to ensure that the elevator doors cannot be opened under the action of external forces to ensure the safety of personnel. The electrical ones are the premise that the electrical switches are all connected. The elevator can only run when the door is closed, and the pin on the door knife in the car door lock is inserted into the socket of the fixed hook assembly. According to the regulations in the elevator safety regulations, the elevator can have a A certain opening distance, that is, the socket on the fixed hook assembly can follow the pin on the door knife to move a certain distance, so the sliding mechanism will be installed on the fixed hook assembly. At present, the more common follow-up switch mechanisms include the fixed hook plate, the fixed hook There are two shafts installed on the board, and sliders are set on the two shafts. The socket is fixed on the sliders, and a compression spring is installed on one side of the sliders. The follow-up switch mechanism of this structure has a heavy structure. , Complicated assembly, large amount of socket shaking and other shortcomings.

Utility model content

The technical problem solved by the utility model is to provide a car door lock follow-up switch structure with smooth operation, simple structure and stability.

The technical solution adopted by the utility model to solve the technical problem is: a car door lock follow-up switch structure, including a fixed hook plate installed on the door machine plate, a linear slide rail is fixed on the fixed hook plate, the A slide block movable on the linear slide rail is installed on the linear slide rail, the socket mounting bracket is fixed on the slide block, the socket fixedly connected with the socket mounting bracket is also included, and the extension spring is fixed at one end On the fixed hook plate, the other end of the extension spring is fixed on the socket mounting bracket.

Further, a first door panel buffer pad is provided on the upper part of the socket mounting bracket near the outer door knife.

Further, the side of the fixed hook plate close to the outer door knife is provided with a fixed hook side plate, and the lower part of the socket mounting bracket is provided with a second door panel buffer pad on the side close to the fixed hook side plate.

The beneficial effects of the utility model are: the car door lock follow-up switch structure of the application uses the combination of the linear slide rail and the slider to make the slider run more smoothly, stable, and the amount of shaking is small. At the same time, the structure has a simple structure. , The characteristics of simple installation.

Description of drawings

Figure 1 is a schematic diagram of the structure of the car door lock follow-up switch.

Marked among the figure is: fixed hook plate 1, linear slide rail 2, socket mounting bracket 3, socket 5, extension spring 6, first door panel buffer pad 7, fixed hook side plate 8, second door panel buffer pad 9.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

A car door lock follow-up switch structure as shown in Figure 1 includes a fixed hook plate 1 installed on the door machine plate, a linear slide rail 2 is fixed on the fixed hook plate 1, and a linear slide rail 2 is fixed on the linear slide rail 2 A slide block movable on the linear slide rail 2 is installed, a socket mounting bracket 3 is fixed on the slide block, and a socket 5 fixedly connected with the socket mounting bracket 3 is also included, and an extension spring 6 is also included, and the extension spring 6 One end is fixed on the fixed hook plate 1, and the other end of the extension spring 6 is fixed on the socket mounting bracket 3. When the door is closed, the push plate of the door knife moves to the right against the slider and overcomes the force of the extension spring 6. After moving to a certain position, the lock hook of the door knife falls to achieve mechanical locking, and at the same time the pin on the door knife falls to the socket 5 to realize electrical locking. When the elevator needs to pick the door, the door knife will move to the left, and Due to the setting of the slide rail, the socket 5 will move to the left synchronously with the plug on the door knife, and the plug will not be damaged in the socket 5. Under the effect of 6, slide block drives socket 5 to reset. The car door lock follow-up switch structure of the present application uses the combination of the linear slide rail 2 and the slide block to make the slide block run more smoothly, stably, and has a small amount of shaking. Simultaneously, the structure has the characteristics of simple structure and simple installation.

On the basis of the above, the top of the socket mounting bracket 3 is provided with a first door panel cushion 7 near the side of the outer door knife, and the setting of the first door panel cushion 7 makes the push plate of the door knife push the socket mounting bracket 3 at the beginning The moment of moving to the right is against the first door panel buffer pad 7, thereby reducing the impact on the socket mounting bracket 3 and making the assembly run more stably.

On the basis of the above, the fixed hook plate 1 is provided with a fixed hook side plate 8 near the side of the outer door knife, and the bottom of the socket mounting bracket 3 is provided with a second door panel buffer pad 9 near the side of the fixed hook side plate 8. The setting of the second door panel buffer pad 9 can reduce the impact on the socket mounting bracket 3 when the socket mounting bracket 3 moves to the fixed hook side plate 8 direction.

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the present utility model in detail. It should be understood that the above descriptions are only specific embodiments of the present utility model and are not intended to limit the present invention. For the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
