Abstract

The utility model provides to an external lifting and internal pressing type inserting core lock body, which comprises a shell body, an internal poking peach, an external poking peach and a square tongue plate. The internal poking peach and the external poking peach are both axially mounted in the shell body, the square tongue plate is mounted beside the internal poking peach and the external poking peach, a locking slot is mounted on one side of the square tongue plate, a pulling and drawing plate is mounted between the internal and external poking peaches and the square tongue plate, a hook head is provided on the internal poking peach and is positioned on one side of a pulling and drawing bending hook, a pulling nail is provided on the external poking peach and is positioned on the other side of the pulling and drawing bending hook; and the locking slot on the square tongue plate has a sawtooth shape. The lock body can lift the holder to lock the door outside the door and press the holder to open the door inside the door. The lock body can also use a key or a knob to open or lock the door. The internal holder is pressed and the inclined tongue and the square tongue are opened simultaneously, which implement the outside door locking of the inserting core lock without key.

Description

A kind of external extracting and internal pressing type core intercalating lock

Technical field

The utility model relates to the lockset accessory, specifically is a kind ofly just can lock a door mentioning handle outdoors, depresses handle and just can open the door in door, locks a door without the mortise lock body of key.

Background technology

The big mortise lock body of Xiao Shouing in the market, its lock body generally is to open oblique tongue with handle, with key or the knob side of opening tongue, can not the side's of opening tongue with handle, need when in case of emergency, can incur loss through delay and open the door with two actions when opening the door.

Lock a door and must draw out key when locking a door outdoors, it is convenient inadequately to use.

Summary of the invention

The purpose of this utility model just provides a kind of locking a door outdoors without key, depresses the big mortise lock body that action of handle just can be opened the door in door, the process of opening the door and locking a door with simplification.

The utility model achieves the above object by the following technical solutions: comprise housing, interior group peach, outer poking peach, side's hyoplastron, in dial peach and outer poking peach is coaxial is loaded in the housing, side's hyoplastron is loaded on by the interior outer poking peach, there is lock slots on one side at this side's hyoplastron, in described, be provided with draw back plate between outer poking peach and the square hyoplastron, one end of this draw back plate has a circular hole, the other end has a mounting hole, there is a push-and-pull crotch at the middle part, the circular hole of draw back plate is packed that a post of housing nails on into and is rotated around this post nail, the post that the mounting hole of draw back plate is packed on described side's hyoplastron nails on, and dialling on the peach in described has a gib head, and this gib head is positioned at push-and-pull crotch one side; One ejector pin is arranged on outer poking peach, and this ejector pin is positioned at the opposite side of push-and-pull crotch; Lock slots on described side's hyoplastron is a zigzag.

After adopting technique scheme, when handle retracted oblique tongue in rotating, the push-and-pull crotch that the gib head hook on the interior group of peach moves on the draw back plate retracted draw back plate, thereby square hyoplastron is retracted, and realizes opening the door; And outside mentioning during handle, the ejector pin on the outer poking peach just outwards promotes the push-and-pull crotch of draw back plate, and draw back plate is extrapolated, thereby square tongue is released, and realizes locking a door.The zigzag lock slots side of making hyoplastron on side's hyoplastron can successfully be released by draw back plate, does not lock a door and can not influence.Like this, the utility model has just been realized locking a door with handle outdoors and need not using key, depresses action of handle and just can open the door in door, has simplified the process of opening the door and locking a door.

The utility model is described in further detail below in conjunction with drawings and Examples.
