Description

Chain-type multi-piece movable door synchronous moving device

The present invention relates to a chain-type multi-piece movable door synchronous moving device, in particular to a chain-type multi-piece movable door synchronous moving device that cooperates with a chain and can synchronously move all movable doors.

According to the information, using movable doors to move horizontally is a common actuation method for opening and closing doors, which can effectively save space. However, the known movable door devices often move the door to the limit range, and then drive the next door to open and close through the resistance between the doors. Therefore, the degree of opening and closing of each door will be uneven, and the door may be damaged due to the collision between the doors when opening and closing quickly, and the collision will generate vibration and noise. Therefore, it is necessary to move and open all movable doors synchronously.

Furthermore, known movable doors are also widely used on machine tools, allowing users to close the machine tool by pulling the door to isolate the inside and outside for processing. The vibration caused by the collision between the door bodies and the pull also has the concern of damaging the machine tool and the workpiece in the long term, thus affecting the accuracy.

Therefore, the inventor of this invention took this into consideration and came up with the idea of invention. He then designed it based on his years of experience, conducted many discussions and conducted sample tests, and made many revisions and improvements before launching this invention.

The present invention provides a chain-type multi-piece movable door synchronous moving device, which has the function of cooperating with the chain and being able to synchronously move all movable doors, thereby reducing the collision between the movable doors.

The present invention provides a chain-type multi-piece movable door synchronous moving device, which includes a synchronous moving device, wherein the synchronous moving device has a device body, the device body is fixedly provided with a fixed door part and several guide rails, the fixed door part is sequentially provided with several movable door parts and a sliding door part from the inside to the outside, the movable door part, the sliding door part and the guide rail are combined to be slidable, and each movable door part is provided with a rolling part, the rolling part is composed of two rolling gears clamped together with a chain, and the chain is composed of several link units. The fixed door, movable door and sliding door are connected by a plurality of pull members, one end of the pull member is combined with the fixed door, movable door or sliding door and the other end is combined with the chain. When the user pulls the sliding door or the movable door, the chain of the adjacent movable door will be rolled and the rest of the pull members and the chain of the combination will be synchronously pulled, so that the fixed door, movable door and sliding door can be moved and retracted at a synchronous speed and distance.

Furthermore, one end of the pull member is locked on the fixed door part, the movable door part or the sliding door part, and the other end is provided with a plurality of locking pieces passing through the gap between the front and rear of the link unit and locked with at least one locking plate, thereby restricting the link unit between the locking piece and the locking plate. When the user slides the sliding door part, the locking piece pushes the link unit to roll the chain.

Optionally, the latching door portion is provided with a handle for holding.

Furthermore, the synchronous moving device is provided with a stop mechanism, one end of which is fixed in the fixed door portion and the other end is fixed in the movable door portion or the stop door portion, and the movable door portion or the stop door portion can be stop by the extension and contraction of the stop mechanism.

Optionally, the braking mechanism is driven by oil pressure.

Optionally, the actuating mechanism is pneumatically actuated.

Furthermore, the synchronous moving device is provided with a motor to drive the winding gear to rotate and wind the chain.

The main purpose of the present invention is that, since a plurality of pull members are provided between the fixed door part, the movable door part and the sliding door part for connection, one end of the pull member is combined with one of the fixed door part, the movable door part or the sliding door part and the other end is combined with the chain, so that when the chain is rolled, the pull member combined with it chain rolls all the chains, so that all the chains are rolled at a synchronous distance and speed, so that the movable door part and the sliding door part are synchronously moved and unfolded, so as to avoid the fixed door part, the movable door part and the sliding door part from being unfolded in sequence in a manner of mutual collision, thereby reducing the vibration of the synchronous moving device and improving the unfolding efficiency of the fixed door part, the movable door part and the sliding door part.
