The internal structure of the tube well door lock

• Cam structure

The deadbolt mechanism is the executive mechanism for the closing and opening of the ball lock. It only needs to be composed of a large deadbolt, a small deadbolt, a large support body, a small support body, a pull piece, and a brake pad.

• Big back

The large support body is the main part that drives the movement of the large deadbolt and is the main body of the large deadbolt installation. The head of the large bracket body is the riveted part of the large lock tongue, the middle rectangular hole can be matched with the hanging lug on the pull tab, the outer step is the snap-in groove of the brake pad, and the lower part can be snapped into the slider jaw, which is convenient for the slider At the same time when the large support body is pushed and retracted, it will not be hindered by the jaws of the slider.

• Small body

The small support body is the main body of the small deadbolt installation and is the main component to control the self-locking of the big deadbolt. The head of the small bracket is used to assemble the small lock tongue, and the protruding triangular part in the middle is used to push the brake pads, so as to eliminate the self-locking of the brake pads to the large bracket body.

• Pull tab

The pull piece plays the role of positioning and releasing self-locking when the big bolt is pulled and retracted. The hanging lug on the top of the pull piece can be inserted into the rectangular hole in the middle of the large support body, so that the large support body can be pulled inward together, and can also slide in the rectangular hole when the large support body is pushed inward. The supporting angles on both sides of the pull tab can move the brake pads to release the self-locking of the brake pads to the large support body {when the large support body shrinks. The small circle in the middle of the pull tab is used for its own positioning, and the protrusions on both sides can make the large support body move in the formed groove, and the lower bayonet can be snapped into the jaw of the slider, and move under the control of the slider.

• Brake pads Brake pads

The big lock tongue is self-locking originally so that the big lock tongue can achieve the function of anti-prying. The two claws at the bottom are used for installation and positioning, the square hole in the middle can be used to install the spring piece, which provides power for the brake pad to reset, and the top plane is the braking plane, which can be snapped into the self-locking part of the large bracket.

• Lock mechanism

The lock body mechanism is a conversion mechanism that converts the rotation of the handball into the translation of the deadbolt to realize locking. The transmission parts mainly include a large lock tube, small tube, slider, hook block, button large tube, hook, and other parts. The large pipe of the lock end plays the role of fixing the lock end and transmitting torque and is the skeleton for installing the handball. The two shifting feet protruding from the head of the big tube of the lock head are used to move the slider, the two raised parts are used for axial positioning, and the three holes in the middle are used for installing the pin leaf spring and the big tube pin. The large pipe pin can be pressed to stop the movement of the handball, and it is the key to loading and unloading the handball. The two wide slots at the end of the large tube are used to install the lock head. When the large tube is round, there is a wide gap at the joint, which is used to cooperate with the inner convex rib of the handball to prevent the radial rotation of the handball on the large tube, and to cooperate with the hook to prevent the outer handball and the large tube Turn around threaded flange.

Ventilation door lock structure

A window ventilation lock. Technical background Nowadays, people have higher and higher requirements for quality of life.

It is locked when there is a certain ventilation gap, so as to prevent thieves from climbing in. However, there are still some disadvantages to this lock. First, the deadbolt is straight and inserted into the positioning hole of the positioning plate without any hooking position. As long as the thief Uses a tool to pry the positioning plate for a certain distance to withdraw the deadbolt from the positioning plate.
