SHIBUTANI airtight lock

Air-tight lock
Sealed doors must be equipped with imported special air-tight locks. Air-tight locks are usually point-fastened (top, bottom, middle), but according to actual needs, the linkage lock body can also be added to increase the fastening points to improve the air-tight effect. It can be equipped with a special air-tight clamping handle, and the door can be locked after locking. The body provides strong side pressing force to reduce the gap between the sealing strips and further increase the sealing performance. The upper and lower linkage pins must have an adjustable roller guide structure, which not only reduces the vertical error of the pin tongue during construction to facilitate installation, but also reduces the distance between the pin tongue and the pin. At the same time, it provides side pressing force on the door body at the top and bottom of the door body to reduce the gap between the sealing strips and further increase the sealing. All closed doors are also equipped with auxiliary door locks, and the door locks use stainless steel locks. The auxiliary door locks are only used as Safety management means.
Airtight lock (sealed door)
An airtight lock consists of one or more linkage lock bodies, up and down linkage bolts, lock cylinders, handles and door bottom seals
Air The airtight lock is usually defined as point fastening (top, bottom, middle), but in order to improve the airtight effect, point fastening can also be achieved by adding a linkage lock body.
The handle is available in standard large handles and clamping handles. The clamping handle can provide side compression force on the door body in the locked state to reduce the gap between the sealing strips and further increase the sealing. The rotation angle range of the handle is degrees. During installation, the handle is horizontal when the unlocked state is and vertical when the locked state. A variety of options are available to meet the usage habits of different users. The linked unlocking and locking of the lock tongue and the upper and lower latches can be easily completed by controlling the handle.
The length of the upper and lower linkage latches is accurately calculated and customized according to the height of the door body, and the pin rod ∮ , threadedly connected with the lock body. The head of the latch is specially inlaid with a brass sleeve to greatly enhance the wear resistance. The latch stroke is up to 100 meters. The latch pin box is specially made into a roller guide structure, which can be used when the door body is installed with an airtight sealing strip. The movement of the pin tongue in and out of the latch box is softer and smoother. The natural gap between the pin tongue and the pin box is smaller and the fit is closer. At the same time, the lateral pressing force of the upper and lower lock tongues is provided. After the installation is completed, the contact point can be made through the adjusting screw of the pin box. Fine-tuning makes construction easier and more precise.
The lock body is heavy-duty and impact-resistant. The lock tongue has a long stroke and is suitable for door gaps, making the selection of door seals wider and easier to install. The lock plate must be equipped with There is a contact sensor head to sense the contact signal from the lock body to ensure that the handle is inactive when the door is open (that is, the upper, middle and lower lock tongues cannot be extended) to effectively prevent the door frame and the ground from being hit due to misoperation. Damage.
The air-tight lock handle cannot be rotated after the door body is closed and the lock cylinder is locked. However, the handle design must have a special protection device to unload the abnormal and strong pressure in the fixed state and completely avoid damage to the rotating shaft.
There are matching special automatic door bottom sealing strips available to ensure that the bottom of the door is pressed and sealed simultaneously when the door is closed and locked.
According to the improvement of the owner's requirements during construction or application, the original ordinary airtight lock body can be Upgrade and replace it with an electric lock body to meet the networking requirements with access control, but the door body does not need to be modified.
