Description
Technical field
The present invention relates to a kind of unlocking apparatus, especially mechanical code lock core.
Background technology
Security door is on the market divided into mechanical lock security door and electronic lock security door, but these security doors all need application machine lock core, the structure that door lock is separated, and cause having gap and keyhole, the built-in handle of door, opal etc. are by the hidden danger of technical opening.
Indoor opening device is generally utilize mechanical handle directly to open, and electronic lock security door great majority utilize button to open.Because these opening devices are generally exposed in indoor, use instrument to reach the object directly opening security door by opal, be among the peoplely commonly called as fishing opening ways, this mode be utilize iron wire and special tool to press down, under carry and rotate unlatching burglar-proof door.
Summary of the invention
The object of this invention is to provide a kind of drawback lock device, can effectively prevent from using the phenomenons such as instrument unlatching burglar-proof door by opal.
The technical solution adopted for the present invention to solve the technical problems is: comprise handle, lock body, and described handle has recessed, also comprises button, bearing pin, lever, locking plate, fixture block; Described button be placed in recessed in, described lock body establishes the hole with step, and one end of described locking plate is provided with spring; Bearing pin is established at the middle part of described lever, and one end of lever connects button, chain of the other end; Described locking plate extends in the hole with step.
Further, " ⊥ " shape spring base is established on described locking plate top.
The invention has the beneficial effects as follows, can effectively prevent from using the phenomenons such as instrument unlatching burglar-proof door by opal, lever, locking plate, spring are easily installed, and parts abrasion resistance is good, stable performance, and unblank high with antitheft reliability, the Reusability life-span is long.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention exploded perspective view.
Fig. 2 is embodiment of the present invention application schematic diagram.
Fig. 3 is embodiment of the present invention partial enlarged drawing.
Detailed description of the invention
From Fig. 1 to Fig. 3, the present invention includes handle 20, handle 20 has spherical concave 17, also comprises button 10, bearing pin 15, lever 11, locking plate 12, lock body 40; Button 10 is placed in spherical concave 17, lock body 40 apertured 13, and there is step 41 in hole 13, and " ⊥ " shape spring base 18 is established and pocketed springs 30 in one end of locking plate 12, and the other end of spring 30 withstands installing plate 16; Bearing pin 15 is established at the middle part of lever 11, and one end of lever 11 connects button 10, the other end chain 12; Locking plate 12 extends in hole 13, and there is step 41 in hole 13.
Installing plate 16, spring 30, locking plate 12 are connected successively, and locking plate 12 and spring 30 are sleeved in sleeve 50 and also extend in the hole 13 of lock body 40 through locking plate cover 30.
Its operating process is, under normality, locking plate 12 is in hole 13, and because step 41 blocks locking plate 12, handle 20 can not rotate, and dead bolt can not be driven to move and realize opening the door or unlocking action.Open the door as needs or unblank, press push button 10, after locking plate 12 mentioned by lever 11, handle 20 can rotate freely, and realizes unblanking or door opening action.The present invention can effectively prevent from using the phenomenons such as instrument unlatching burglar-proof door by opal, and lever, locking plate, spring are easily installed, and parts abrasion resistance is good, stable performance, and unblank high with antitheft reliability, the Reusability life-span is long.
