Ground lock and ground lock control method for rolling shutter door

Abstract

The invention relates to a ground lock for a rolling shutter door and a control method of the ground lock. The ground lock comprises a base, a lock plate, a control circuit and a lock pressing device;the base is fixedly connected with the ground; a support arm A and a support arm B are arranged on the base; the lock plate is slidingly connected with the support arm A; an electromagnet B is arranged on the support arm B; one end of the lock plate is connected with the support arm B through a spring B; the other end of the lock plate is suspended above the ground; and the electromagnet B is connected with the control circuit. The invention also provides a control method of the ground lock. The control method comprises the steps that a start button, a stop button and a rolling shutter door motor are controlled to response through the control circuit, so that the step of switching the ground lock between an opening state and a closing state is changed. Through the use of the technical scheme, the bearing strength of the ground lock is increased, the problem that the rolling shutter door is prized up due to a gap existing between the rolling shutter door and the ground, the service life of the rolling shutter door is prolonged, and the phenomenon that the ground lock collides with the rolling shutter door due to negligence is avoided.

Description

technical field [0001] The invention belongs to the technical field of rolling door locks, and in particular relates to a ground lock for a rolling door and a control method for the ground lock. Background technique [0002] Rolling shutter door, also known as rolling shutter door, is a door that is connected in series with multi-joint movable door pieces, and rotates up and down around the scroll shaft above the door in a fixed slideway. Rolling shutter doors are widely used in large shopping malls and industrial enterprises. The structure of rolling shutter doors generally includes curtains, negatives, reels, slides and motors. The slides are set on both sides of the door frame, and the motors are connected to the reels. On the reel, the film is connected to the bottom of the multi-joint door curtain. When the above-mentioned rolling door needs to be opened or closed, the motor needs to be started first to drive the motor to rotate the reel. At this time, the multi-joint d...

Problems solved by technology

Using the technical solution of this utility model, the lockset is connected with the ground as a whole, and the safety of the rolling shutter door is improved to a certain extent, but the utility model has the following problems in use. On the one hand, due to the connecting piece and the The baffle is hinged together, and the connecting piece is mainly used to bear the locking force. When a large prying force is used to pry the rolling door, the load capacity of the connecting piece is limited, which cannot greatly improve the safety of the rolling door. Especially when the lock is used for a long time, when the spring, connecting piece and baffle are rusted, it will seriously affect the use effect of the lock. On the other hand, since the lock is placed on the ground, if the operator does not notice When the lock has already locked the rolling door, the motor will open the rolling door, which will cause the lock to collide with the film of the rolling door, thereby causing damage to the rolling door, affecting the use effect and the service life of the rolling door. For another example, the publication number is "CN202596337U " patent document discloses a rolling shutter door power-off lock, including a lock seat installed under the rolling door, a lock bar and a signal controller, the lock seat is fixedly connected to the ground, and a lock is arranged inside the lock seat. tongue, the lock bar can be inserted into the lock seat to lock with the lock tongue, the lock tongue is fixedly connected with a control switch, the rotation of the lock bar can control the on / off of the control switch, the control switch and the signal The controller is connected, and the signal controller is electrically connected to the power supply and the rolling door motor respectively. Using the technical solution of the utility model, it solves the problem that the user opens the rolling door by remote control without opening the lock body, which will cause the rolling door and the lock body to pull each other. problems such as damage

However, when this utility model is used, the load that the ground lock can bear is still very limited, which affects the further improvement of the safety performance of the rolling shutter door. On the other hand, the operator still needs to observe the state of the ground lock before starting the motor. Even if the operator is negligent, it is still unavoidable that the ground lock and the rolling door collide with each other.
