Abstract
The utility model relates to a mechanical angle cipher lock. The utility model is characterized in that a plurality of rows of bead holes which are arranged in angles are arranged at a corresponding part between a lock (3) and a lock core (9). The bead holes and a center line of the lock core divide a central point and slant an angle alpha, and marbles in the bead hole correspondingly form three basic states which are a vertical state, a left slant angle state, and a right slant angle state. The lock has high security level because of the arrangement with a plurality of rows in angles of the bead holes of the utility model. The lock is provided with a drilling-prevention device which can be used for preventing drilling and preventing sawing. The utility model has the advantages of high theftproof performance, convenient installation, convenient use and good practicability.
Description
The utility model relates to a kind of mechanical type cylinder lock, particularly a kind of mechanical type Coded bullet lock.
At present, the mechanical type cylinder lock has generally obtained application, and style is also more and more, and function has obtained updating, for positive effect has been played in social security antitheft.But present mechanical type cylinder lock is because the unidirectional array in the hole of bead, in order to increase the hole of bead, the number that also promptly increases pellet shot from a slingshot can only be to increase on unidirectional, so just force lock core and tapered end to strengthen, but lock core and tapered end can not be infinitely great, limited the number in the hole of bead of unidirectional array so again, so theftproof also is subjected to certain restriction.In addition, the lockhole of prior mechanical cylinder lock opens wide, and tapered end does not have anti-boring device, and this also utilizes simple tools can open lock to other people and has stayed future trouble.
The purpose of this utility model provides a kind of mechanical type angle coded lock, the angled many rows' in the hole of bead arrangements just can improve the level of confidentiality of lock under the condition that does not strengthen tapered end and lock core, do not seal when the lockhole of lock has the key insertion in addition, and tapered end is provided with anti-boring device, improves the theftproof performance of lock.
Technical solution of the present utility model is, at the tapered end of existing machinery formula cylinder lock, and lock core, the pearl spring, ring washer is on the basis of driver blade.The utility model particularly tapered end and lock core corresponding position is provided with and lines up the hole of bead that angle is arranged more, the hole of bead and lock core center line composition central point skew-a angle, and the pellet shot from a slingshot in the hole of bead forms in tapered end vertically, the three kinds of basic status in left avertence angle and right avertence angle.
The front end of above-described tapered end has anti-drilling lid and anti-drilling sheet, is provided with two cylindrical spoon door bolts in the square groove in anti-drilling sheet, in the both sides of spoon door bolt two springs is arranged respectively, in the rear end of anti-drilling sheet cover plate is arranged.
The utility model is riveted on anti-drilling lid on the tapered end with pin, the anti-drilling sheet that is equipped with in the endoporus of tapered end can freely rotate, two cylindrical spoons of door bolts that are equipped with in the anti-drilling sheet inside groove are under the effect of spring, two spoon door bolts are in closure state, and seal with cover plate, in the corresponding position of tapered end and lock core, three row are in the hole of bead of composition central point skew one a angle the decorative pearl on top of an official cap, flat pearl and spring to be housed with the lock core center line, driver blade is housed in the lock core pit and has ring washer to block.It is the Type B pearl that pellet shot from a slingshot of the present utility model is provided with common pearl, and the angle pearl is an A type pearl.Key of the present utility model is established the tartar groove, and the bottom of tartar is provided with parallel surface and left avertence angle and right avertence angle.
Operating principle of the present utility model is when key inserts, at first the spoon door bolt is backed down to both sides respectively, enter to the location afterwards, this moment, the decorative pearl on top of an official cap fell into the bottom of tartar on the key in the effect of spring force, when the tartar in the key and the decorative pearl on top of an official cap number match, just decorative pearl on top of an official cap face is equal with the lock core external diameter, so key drives lock core and rotate together with driver blade, locks promptly to be opened.The utility model is lined up the hole of bead that angle is arranged more because of the corresponding position at tapered end and lock core is provided with, the pellet shot from a slingshot number of arranging in a certain size tapered end and lock core is just much more than the pellet shot from a slingshot number in the hole of bead of unidirectional array like this, so just realized not strengthening the level of confidentiality that has improved lock under the condition of tapered end and lock core, also therefore we can say the relative thickness that reduces to lock, thereby can install by convenient construction, use and indoor attractive in appearance, and the anti-drilling lid that the tapered end front end is equipped with, the anti-boring device of activity anti-drilling sheet and anti-drilling spoon door bolt is to have broken the design that the machine-made keyhole that follows of mechanical type cylinder lock opens wide, and has realized the function of anti-drilling anti-saw.
The utility model has the advantages that the angled many rows' in the hole of bead arrangements, the level of confidentiality height of lock, tapered end is provided with anti-boring device, can anti-drilling anti-saw, the utility model theftproof performance is good, installs, easy to use, and practicality is good.
