Abstract

The invention discloses a password handle door lock. The password handle door lock comprises a nut movable lug (1). The nut movable lug (1) is connected with a semicircular switch movable lug (2) which is connected with a thread lock (3), a hexagonal nut (4) and a coded lock (8) in sequence. A through hole (7) is formed in the coded lock (8), and the outside of the coded lock (8) is connected with a convex column (5). A door handle (6) is further connected to the coded lock (8). According to the password handle door lock, gaskets are prevented from being used for unlocking the door lock, conventional linear paratactic unlocking is changed, turning sounds of each time are made to be almost the same, unlocking of the door lock is convenient, and the function that the door lock can only be unlocked on condition that the door lock must be matched with the angle of the door handle is achieved.

Description

A kind of password handle door lock

Technical field

The present invention relates to a kind of construction of switch of door lock, in particular for bookcase, the password handle type door lock of locker etc.

Background technology

Rotate input type coded lock generally containing combination disk, password tongue, runner, several primary clustering such as lock body, the coded lock be used on padlock or casket ten thousand can be only have a rotating disk.Rotating disk promotes the back of the body several balance video disc of Hou or cam.Traditionally, first rotating disk is forwarded to first digit clockwise when opening this lock, right Hou counterclockwise rotation is to second digit, like this until most Hou numeral.Cam has recess usually, and when proceeding to correct password Hou, everybody locks and just can open in line.

But there is following common shortcoming usually:

1: partial password padlock can strain tapered end, right Hou rotates rotating disk until can not move again, so just password can be found out.There is particular kind of relationship between the numeral of also some turntable coded lock, make the combinatory possibility of password greatly reduce.Cheap cipher hang lock can be opened with special liner, and without the need to accessing to your password.

2: experienced locksmith can one side rotary turnplate, one side use receiver carefully listen to lock cam ring sound, judge possible password.

3: coded lock runner surrounding is smooth, need larger dynamics by driven by rotating wheel movable lug of unblanking, user uses inconvenience, easily skids between hand and runner.

Summary of the invention

The technical problem that the present invention solves is: provide a kind of password handle door lock, prevent liner opening door lock, change conventional straight line and unblank side by side, make to rotate each time sound all almost identical, convenient unlatching, and door lock is necessary and the design of door handle angle formation coupling ability opening door lock.

The technical solution used in the present invention is: a kind of password handle door lock, comprise nut movable lug, nut movable lug is connected with semicircle switch movable lug, semicircle switch movable lug is connected with screw fastening, hexagon nut and coded lock successively, coded lock has through hole, and be connected with protruding post outside it, coded lock is also connected with door handle.The end face of coded lock is provided with combination disk, the housing of coded lock is provided with measuring point.

Protruding semi-cylindrical in configuration can prevent from liner from stretching into door lock causing this rolling-code to be locked directly being unlocked, coordinate halfround bar slice, when door handle rotational angle is not right, even if when combination disk password is correct simultaneously, if early stage door handle to suit angle incorrect, also cannot open door lock.User in use, oneself can define door handle angle, combination disk password is set in respective angles, so before input combination disk password, just needs door handle to rotate to respective angles, unfamiliar people cannot expect that the prerequisite key element of opening the door is door handle angle at all, during input password, combination disk 11 drives handle threads turn, the match is successful rear thread auto-articulated, drives first movable lug immediately, from swing handle again and opening door lock, this is that combination disk transcoding will be upset.

Accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present invention;

Fig. 2 is coded lock detailed drawing.

Detailed description of the invention

As shown in Figure 1, nut movable lug 1 is connected with semicircle switch movable lug 2, rotarily opens control by screw fastening 3, and lock body can be limited within doorframe by semicircle switch movable lug 2, and rotating can opening door lock after opening.Below use hexagon nut 4 drive protruding post 5, prevent the liner of this kind of lock class from opening.Through hole 7 uses when repairing coded lock 8 for loading and unloading, and swing handle 6 can passwords lock 8. to certain angle

As shown in Figure 2: rotational password dish 9 can drive rotating shaft 11 to rotate, and then drive screw fastening 3 rotation to unblank, this tumbler can meet side and drive screw fastening 3, there is housing 12 coded lock 8 outside, when turn the handle 6 time can not drive housing 12, when door handle angle is mated with the measuring point 10 on housing 12, just can carry out next step input password, no person cannot open, and during unlatching, screw thread runner is in transmission connection by the linkage in lock body and movable lug, realizes incorgruous door lock and opens.
