Description

Automatic-locking sliding door

Technical Field

The utility model relates to a push-and-pull door specifically is an automatic closedown push-and-pull door.

Background

The existing sliding door needs to be manually locked for preventing automatic opening after closing, so that the use is inconvenient.

Disclosure of Invention

The utility model provides a current push-and-pull door is automatic to be opened and all needs manual shutting after preventing to close, provides an automatic closedown's push-and-pull door for the problem that the use was inconvenient.

The utility model discloses an adopt following technical scheme to realize: automatic closedown's push-and-pull door, including the push-and-pull door body, be equipped with the keeper on the push-and-pull door body, the one end of keeper articulates on the push-and-pull door body, the other end stretches out the push-and-pull door body, the terminal surface that the keeper stretches out the one end of push-and-pull door body makes the inclined plane, the one end that the keeper stretches out the push-and-pull door body is equipped with the opening couple groove down, be equipped with the lower spacing block that is located the keeper below on the push-and-pull door body, the keeper is the horizontality when the keeper supports in lower spacing block, still be equipped with the upper limit block that is located the keeper top on the push-and-pull door body, the articulated one end of keeper is fixed with the handle, be equipped with the couple pole on the. When the sliding door body is opened, the handle is pulled, the door bolt rotates around the hinged position to be separated from the hook rod and limited on the upper limiting block, and the handle is continuously pulled, so that the sliding door body can be opened. In the closing process of the sliding door body, the sliding door body is pushed through the handle or directly, the hook rod jacks the door bolt through the inclined plane at the end part of the door bolt, and when the sliding door body reaches a closing position, the door bolt falls under the action of gravity to enable the hook rod to be clamped into the hook groove of the door bolt, so that automatic locking is realized.

The utility model discloses can realize that the push-and-pull door closes the door automatic blocking, simple structure, science, reasonable in design has made things convenient for the use of push-and-pull door. The utility model discloses be particularly useful for the colliery underworkings is separated, perhaps the door of automatically controlled room in the pit.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1-a sliding door body, 2-a hook rod, 3-a lower limit block, 4-a handle, 5-an upper limit block, 6-a door bolt and 7-a hook groove.

Detailed Description

Automatic shutting's push-and-pull door, including push-and-pull door body 1, be equipped with keeper 6 on the push-and-pull door body 1, the one end of keeper 6 articulates on push-and-pull door body 1, the other end stretches out push-and-pull door body 1, the terminal surface that keeper 6 stretches out the one end of push-and-pull door body 1 makes the inclined plane, keeper 6 stretches out the one end of push-and-pull door body 1 and is equipped with opening couple groove 7 down, be equipped with lower spacing block 3 that is located keeper 6 below on the push-and-pull door body 1, keeper 6 is the horizontality when supporting in lower spacing block 3, still be equipped with the last spacing block 5 that is located keeper 6 top on the push-and-pull door body 1, the articulated one end of keeper 6 is fixed with handle 4, be equipped with couple pole 2 on the door frame of push-and-pull door body 1, when push-and-. In specific implementation, the upper limit block 5 is positioned to enable the door bolt 6 to be turned upwards by forty-five degrees. The hook groove 7 is wide inside and narrow outside so as to be better clamped with the hook rod 2. The both sides of push-and-pull door body 1 are equipped with the same automatic shutting structure of structure respectively, and the keeper 6 of push-and-pull door body 1 both sides is coaxial articulated with the body, like this, can both upwards overturn the keeper 6 of push-and-pull door body 1 both sides simultaneously and break away from couple pole 2 through handle 4 in any side of push-and-pull door body 1, realize opening of push-and-pull door body 1.
