Abstract

The utility model relates to a code lock, pertaining to mechanical structure. The lock is in a cylindrical shape (diameter 40mm, length 50mm), small in size and easy to install. The utility model well solved the defect of common code locks which are not easy to install. In addition, the lock can prevent thieves from poking, striking and prying. The utility model can be used to replace ball locks to prevent vehicle theft. The lock comprises 8 groups of fixed and movable blades matching the special lock core, and 100 million different codes can be composed to ensure security. Special screws are provided for mounting the lock on a vehicle, door, wall, etc. Because the rear cover plate also has deadlock function, dismantling, installation and password modification become very easy. However, the lock can not be dismantled if the correct password is not available.

Description

Coded lock

Affiliated technical field;

The utility model is a kind of lock of mechanical realization, and especially this lockset has the little characteristics easy for installation of volume of cylinder lock not have disclosing of cylinder lock simultaneously, dials drawbacks such as sled.

Background technology '

Anti-incessantly robber's the special instrument of general in the market cylinder lock especially hands over logical worker's tool Frequency Frequency stolen, and coded lock volume in the market is big, and shape is single, mostly is disc difficulty, cost height are installed.

Summary of the invention;

Long-pending big in order to overcome the existing password lock body, difficulty etc. is installed, the utility model can provide a kind of coded lock, and this lock body is long-pending little, easy for installation, and safety is good, can have 100,000,000 different number sets.

The technical scheme that its technical problem that solves the utility model adopts is: be modified into the disc coded lock cylindrical, with diameter 20MM length is that the round steel of 50MM is made lock, on post jamb, open one and widely be the groove of 2MM deeply for 4MM, putting 8 groups on lock decides, moving plate, lock one end is fixed by the thin plate weldering of a diameter 40MM, and the other end is with screw thread, to decide by threaded back shroud, moving plate is installed on the lock, and stator is fixed on the lock, the stator internal diameter have wide for 4MM long for 2MM[radially] groove and the lock groove square duct that is combined to 4MM*4MM, moving plate is the same with the stator structure, but can on lock, rotate, be carved with totally 10 numerals of 1--10 on the moving plate, under Let fixed number word, open the groove of a 4MM*2MM, rotate moving plate, make notch and lock groove be combined to the square duct of 4MM*4MM, this moment is fixed, the moving plate all align, lock core inserts lock body by the notch of lock, lock core is made by the square bar of 4MM, has deeply in a side of lock core, and wide is the groove of 2MM, the width of groove and fixed, the consistency of thickness of moving plate.This moment, the stator notch became a plane [radially] with the protruding place of lock core, rotated moving plate, and this moment, moving plate can be rotated by lock core spill place, cut off passage,, pin lock core, carry out sealedly, only when whole moving plate notch stator notches alignment, lock core is just actively.As long as change the shape of lock core, just can make diversified lock, have support simultaneously on the T shape lock of this lock screw is installed, be convenient to install.The utility model coded lock have 8 layers fixed, moving plate has 8 figure place passwords, can form 100,000,000 cipher code set, [requirement as the case may be can increase and decrease decide the moving plate layer] is safe and reliable.

The beneficial effects of the utility model are; Can prevent disclosing of robber, dial that the theft of means such as sled because this lock body is long-pending little, easy for installation, can be used for the vehicles, security door etc.

The specific embodiment;

T shape tapered end plate [1] is welded into T shape with T shape lock [3] in Fig. 1, install for convenient, have 2 tapered end timbering holes [2] on the plate, on T shape lock [3], open one wide for 4MM deeply for the lock groove [5] of 2MM to be used to install lock core, the V-arrangement lock holddown groove [6] that the opposite side of going up groove at T shape lock [3] has a 1MM*1MM is with fixing stator [12], the other end at T shape lock [3] is with lock end screw thread [7] with mounting rear cover plate [15], stator [12] be one thick for the 3MM diameter be the ring segment of 20MM for the 40MM internal diameter, have the wide 4MM that is on the internal diameter, it radially is the fixing convex tooth [8] of stator of the stator groove [10] of 2MM and 1MM*1MM, with fixing stator [12], moving plate [11] structure is the same with stator [12], does not only have the convex tooth.Fixed, moving, sheet [11,12] be installed in successively on the T shape lock [3], back shroud [15] is made for thick 5MM steel plate among the figure [5], the center has diameter 20MM upward decides to install for the inner bolt hole of 3MM [16] is used to be screwed in lock end screw thread [7] deeply, moving plate, and the square bonnet board slot [17] that has a 4MM simultaneously is as the lock core passage.Lock core [20] is that the square steel of a 4MM is made among the figure [7], has on its one side widely to be the lock core groove [19] of 2MM and lock core convex tooth [18] deeply for 2MM.To decide, moving plate [11,12] be sleeved on successively on the T shape lock [3], adorn 8 groups, stator fixedly convex tooth [8] matches with lock holddown groove [6], moving plate [11] can rotate, rotate moving plate [11] and make moving plate groove [14] and lock groove [5], the synthetic 4MM's of kissing is square, and with stator groove [10] and bonnet board slot [17] and lock groove lock core passage [4] on same line, this moment is fixed, moving plate [11,12], groove of back shroud [17] and lock groove lock core passage [4] form the square duct of a 4MM, and lock core [20] is inserted passage, rotate moving plate [11] and cut off passage, pinning lock core can't extract and take action, only all moving plate numbers [groove] when all aliging lock core just can move, the lock that is assembled into is figure [9].As long as change the shape of lock core, just can make the lock of various uses.

The beneficial effects of the utility model are to prevent disclosing of robber, dial, and sled is torn open, the theft means, simultaneously should It is the same with spring lock convenient that lock is installed, and can replace spring lock on the market and safe and reliable.
