Description

Mechanical universal handle door lock

The utility model relates to a mechanical door lock.

Existing handle door locks or spherical door locks have the function of rotary opening, which provides convenience for users, and thus has been widely used. But the unlatching mode of present handle door lock or spherical door lock is single, still can not satisfy people's needs.

The purpose of the utility model is to provide a mechanical universal handle door lock, which can not only be opened by rotation, but also can be opened by pushing and pulling, and is easy to use.

The technical solution of the utility model is that the oblique bolt, the oblique tongue plate, the oblique tongue spring, the backing plate, the lock core, the fixed sleeve, the fixed ring, the front cover and the rear cover of the existing handle door lock or spherical door lock On the basis of the utility model, there are two paddles on the fixed sleeve of the utility model, and the push rod is penetrated in the middle of the fixed sleeve, and one end is connected with the button on the rear handle, and on the rear part of the lock cylinder and the opposite surface of the push pin opposite to it. Each has a V-shaped tooth that can mesh with each other. There are cylindrical front sleeves and rear sleeves at the front and rear of the fixed sleeve. There are sliding sleeves and handle cores in the front and rear sleeves. connected by two tension springs.

The above-mentioned push rod is provided with two raised positions.

One end of the front cover and the back cover of the utility model has an inner spherical surface and an outer spherical surface.

Both the above-mentioned sliding sleeve and the handle core have two convex and two concave arc-shaped surfaces matching each other.

The utility model has a spherical surface coincident with the inner spherical surfaces of the front and rear sleeves on the handle core, and an inner spherical surface consistent with the outer spherical surfaces of the front and rear sleeves on the handle.

The working principle of the utility model is that since the structure of the handle core and the sliding sleeve is two convex and two concave arc surfaces that match, one end of the handle core is a spherical surface that coincides with the inside of the front and rear sleeves. Under the force of the spring, the spherical surface of the handle core is close to the inner spherical surface of the front and rear sleeves, the inner spherical surfaces of the front handle and the rear handle coincide with the outer spherical surfaces of the front and rear sleeves, and the connection between the handle core and the sliding sleeve is by two The tension of the extension spring forms a soft connection, the handle core can rotate in multiple directions, and the sliding sleeve can only reciprocate due to the groove-shaped orientation. When the handle rotates, it drives the handle core to rotate, making the handle core rub against the arc surface of the sliding sleeve, so that the sliding sleeve moves forward; when the handle is pushed or pulled, the handle drives the handle core to move directly Push the sliding sleeve to move forward, so as long as the handle drives the handle core to move, no matter in any direction, it will generate thrust for the sliding sleeve.

When the sliding sleeve moves forward, the nail installed on the sliding sleeve will withstand the paddle so that the paddle rotates downward with the pin as the axis, driving the ram to slide, and then the ram drives the latch tongue to move downward and enter the latch tongue Set in complete open.

When the handle is not subjected to external force, the handle core and the handle are automatically reset by the force of the spring, and the oblique tongue and the ram are also reset by the force of the spring.

Press the button indoors, the button moves the push rod forward, and then the push rod moves the push pin forward to engage with the V-shaped teeth in the lock head; at the same time, the protruding part of the push rod enters the slot of the pick , the spring in the button plays a positioning role. Because the paddle is stuck by the push rod, the outdoor handle is also controlled to be unable to move, and a key must be used to open it.

Insert the key into the lock head, and the key drives the lock cylinder to rotate. Due to the effect of the V-shaped teeth, the push pin moves forward, pushes the push rod to reset, and then continues to rotate to complete the opening.

After pressing the button indoors, rotate or push and pull the handle, and when the paddle rotates downward, push the push rod to reset.

The utility model has the advantages that the door lock can not be rotated to open, but also can be pushed and pulled to open the door lock, which is convenient to use.

Embodiment of the utility model is described below in conjunction with accompanying drawing:
