Description

Built-in lock device gone up automatically by antitheft door

Technical field

This utility model relates to a kind of antitheft door and automatically goes up built-in lock device.

Background technology

The antitheft door used in life at present is made up of door body and door lock, and door lock is made up of lock body, lock core and handle.Door body has a peephole, is commonly called as opal, facilitate user to observe outdoor situations indoor, identify visiting personnel.If locking on having forgotten when user gos out, it is plastics due to Spy hole of anti-theft door and eyeglass is made, robber just can take off opal by turn-knob outdoors, or destroy opal with the hard subclass instrument that rises of point, then opal pore pressure door Internal handle is stretched into driving opal instrument soon, just can opening antitheft door easily, opal hole has become security breaches of antitheft door.

Summary of the invention

For the safety defect of above-mentioned existing antitheft door, this utility model provides a kind of antitheft door automatically to go up built-in lock device, it is achieved automatically go up built-in lock at closing time, it is prevented that robber opens antitheft door from opal by Internal handle.

This utility model solves what its technical problem adopted technical scheme: built-in lock device gone up automatically by antitheft door, including handle, it is fixed on the fixing plate shaken hands on wainscot, handle wainscot, fixing plate, location-plate are sequentially sleeved on the rotation axle of handle, the projection of the restricted location-plate rotational angle in fixing plate two ends；Location-plate both sides are circular arc, and limit, circular arc two ends is positive stop end；There is a female locking breach its underpart, and a cylinder lock pin is fixed on movable jam plate top, and cylinder lock pins position, in location-plate female locking breach, has a blank guide chute in the middle part of movable jam plate；The bearing pin of the guide finger on wainscot is placed in guide chute, the guide finger back-moving spring connection activity jam plate by bottom；Movable jam plate bottom has a self-locking grooves；Locking press button includes button, little spring and movable tongue, and tongue piece front portion is wedge angle, and the wedge angle gradient matches with the degree of depth of the female locking breach of location-plate.

Of the present utility model have the benefit effect that back door lock of closing the door is automatically into Internal handle lock-out state so that robber cannot stretch into the tool pressure gate Internal handle that goes into operation soon and open door from opal, solves the security breaches of opal.As long as pressing locking press button during enabling gently can unlock state, just automatically lock after unclamping handle, simple in construction, easy to operate, it is greatly improved the safety of antitheft door.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is elaborated.

From Fig. 1, Fig. 2 it can be seen that built-in lock device automatically by a kind of antitheft door, including handle 1, handle wainscot 8, fixing plate 3, location-plate 2, movable jam plate 4, locking press button 5 and back-moving spring 10.Handle wainscot 8, fixing plate 3, back-moving spring 10, location-plate 2 are sequentially sleeved on the rotation axle of handle 1, and fixing plate 3 is fixed on handle wainscot 8, and it is arranged with two protruding positioning ends, the rotational angle of restriction location-plate 2.Location-plate 2 both sides are symmetric, arc, and location-plate 2 blocks on the rotating shaft and rotates therewith, and a female locking breach 12, limit, circular arc two ends limited location end are arranged at location-plate 2 bottom.A cylindrical lock pin is fixed on movable jam plate 4 top, and during locking, cylinder lock pin is in location-plate 2 female locking breach 12；Having guide chute 11 one section blank in the middle part of movable jam plate 4, the bearing pin of guide finger 9 is placed in guide chute 11；Position, its underpart has a self-locking grooves, and for the locking of the movable tongue on locking press button 5, guide finger 9 is fixed on handle wainscot 8, and by the back-moving spring 7 connection activity jam plate 4 of bottom.Locking press button 5 is fixed on the underface of handle, being made up of button, little spring 6 and movable tongue, the reset response of 6 buttons of little spring and movable tongue, the front portion of movable tongue is pointed design, angle root has a little hook, and the gradient of wedge angle coordinates consistent with the female locking notch depth of location-plate.

During lock-out state, the cylinder lock pin of movable jam plate 4 upper end is in location-plate 2 female locking breach 12, and location-plate 2 can not rotate, and namely handle 1 can not rotate, and the wedge angle of the movable tongue of locking press button 5 and the edge of self-locking grooves are in firm contact position.

During enabling, first locking press button 5 is pressed, movable tongue is inserted in the self-locking grooves of movable jam plate 4 and travels forward, the hypotenuse of its wedge angle forces movable jam plate 4 to move down along gathering sill 11, when moving to the end of hypotenuse, the little hook of movable tongue just hooks movable jam plate 4 and locks, and now cylinder lock pin is completely out, location-plate 2 is in delocking state, and handle 1 can rotate.When user rotates down handle 1, it drives door tongue to move door opening process.Meanwhile, the arc-shaped edges of female locking breach 12 can make cylinder lock pin continue to move down, and when the self-locking grooves bottom on movable positioning plate 2 is lower than the oblique hook of locking press button 5 tongue piece, locking press button 5 resets under the effect of little spring 6；When user unclamps handle 1, movable positioning plate 2 then moves up reset under back-moving spring 7 acts on, and again handle 1 is placed in lock-out state, has namely automatically gone up built-in lock.Now closing behind the door cannot from being opened the door by the mode of pressure handle hands outdoors, it is achieved anti-opal unlocking function, improves antitheft door safety.
