Description

A password lock with a password

Technical field

The invention relates to a password lock latch for a variety of doors or bicycles and electric bicycle locks. The latch is connected to the latch positioning body with a password, so that the ordinary door lock or padlock can be a password lock. Background technique

In daily life, people have invented many mechanical code locks from the need of security and anti-theft. In the past, mechanical code locks can be mainly divided into two categories: one is the function of password by the cooperation of lock core and cryptographic device. For example, the domestic patent specification CN200710033014. 3 discloses a mechanical lock of a lock cylinder and a password setting device placed in the lock body; the other is to directly place a mechanical cryptographic device on the door, and the keeper is used to control the door handle. Rotating, thereby realizing the function of the password, such as the domestic patent specification CN200810070043. 1 discloses a support plate, a driven code wheel, an active code wheel, a password slot insert and a fork wedge plate integrated with the password slot insert, etc. A knob type mechanical code lock composed of components. However, the above password lock still has insufficient components, complicated structure, large size, etc. As the CN200810070043. 1 patent, in order to prevent the password of the mechanical code lock from being detected, the basis of the mechanical code lock used on most safes is increased. Less components. Can you design a simple, low-cost structure that can overcome the possibility of the password lock being detected when the mechanical code lock is turned on? Summary of the invention

The technical problem to be solved by the invention is to provide a password latch with difficulty in breaking code, simple structure and small volume, the password plug is applied to an ordinary lock, and the ordinary lock becomes a password lock, and is suitable for various types due to its small size. Padlock.

In order to solve the above technical problem, the basic idea of the present invention is: The simplest door lock is simply a latch of a locking door. Through the linear movement of the bolt, the locking and separating of the locking bolt and the locking groove are completed, thereby realizing the opening and locking of the door. The function. In order to make the ordinary door and window lock have the password function, the bolt can be provided with a lock bolt or a lock slot, and the linear movement of the bolt allows the lock bolt or the lock groove on the bolt to lock with the lock groove or the lock bolt of the door or the lock. Separate to realize the function of unlocking, or to realize the function of unlocking by locking the lock bolt of the lock body by linearly moving the latch, and locking and locking the lock slot and the lock bolt to realize the unlocking function. The latch is connected to the latch with the password. Physically, the linear movement of the pin is limited by the password, so that the linear movement of the pin is ultimately controlled by the password. In order to realize the function of the password, the pin positioning body of the password pin is a disk or a cylinder with a circular passage in the middle, and a ring of convex rings extends inward along the outer edge of the channel or the disk, and more than one blocking disk is sleeved on the ring. Or placed in the ring, the end of the pin is a button handle, and more than one paddle is provided at the end of the button handle, and the button on the pin is placed through the pin positioning body and the paddle is placed on the blocking plate or the ring, in each The blocking plate is provided with more than one pad positioning groove and one or more protrusions for the paddle to be dialed, and the pad or the blocking ring is rotated by the paddle, so that the password on the blocking disk or the blocking ring rotates together; When the paddle is inserted into the paddle positioning slot, the restriction on the linear movement of the latch is eliminated, thereby opening the lock. Of course, such a design is the same on the external lock, as long as the external lock is also driven by the linear movement of the bolt to lock and separate the lock and the outer lock ring, and thus the external lock is a password lock. How is this done? The following is a detailed description of the technical solutions.

As a first technical solution for realizing the basic idea of the present invention, a password-based lock password latch is composed of a latch and a latch positioning body, and the dial can be disposed on the latch positioning body, and the latch pin of the password latch For the disc or cylinder with a round hole in the middle, a circular ring is extended inward along the circular hole or the outer edge of the disc, and more than one paddle positioning groove can be opened on the ring, and the pin positioning body is fixed. On the door or the lock body, more than one pad positioning groove is arranged on the blocking plate, the pin end is a button handle, and more than one paddle is arranged at the end of the button handle, and the button handle on the pin passes through the pin positioning body. The paddles are placed on the blocking disc or the ring, and more than one pad positioning groove and one or more bumps are arranged on the blocking plates for the paddles to be dialed, so as to meet the paddles and dial the blocking plates and the blocking plates. Supporting the sheets, each of the blocking discs may be sleeved on the ring or placed in the ring according to the diameter, and the corresponding cross-section of the pick-up piece is stepped, and the steps are respectively placed on the ring and the blocking plate or both are placed on Each of the blocking discs, each blocking disc and the ring a rotatable connection by interposing a ratchet groove and a pawl between the blocking disk and the ring or a tab or the like under the blocking disk; or each blocking disk is provided with a circle from the second blocking disk by size The ring sleeve is sleeved on the inner side of the barrier disk or each of the barrier disk and the ring can be rotated only by providing a ratchet groove and a pawl between the barrier disk and the ring or a supportable piece under the barrier disk. The discs are on the same side, and the corresponding picking pieces extend to the outermost one of the blocking discs, so that the picking sheets can be respectively placed on the ring and the blocking disc or placed on the respective blocking discs, and the picking grooves are positioned. When a large positioning groove is formed after alignment, the positioning of the paddle can be satisfied.

When the cross-section of the pick-up piece is stepped, each step is respectively placed on the ring of the pin positioning body and the blocking disk or both are placed on the blocking plates, and the positioning grooves of the paddles are aligned to form a large positioning groove. Thus, under the restriction of the cylindrical surface of the paddle and the pin positioning body, the blocking disk can only rotate with the pin around the same center. When the pin is rotated, when the first step of the paddle passes over one of the blocking plates, the pad positioning groove or the pin positioning body When the paddle on the ring locates the position of the groove, the second step of the paddle is still placed on the other blocking plate, so that the paddle can pass smoothly, and when the second step of the paddle passes through the block When the position of the paddle positioning groove on the disk, the first step of the paddle is still placed on the ring of the blocking plate or the pin positioning body, so that the paddle can smoothly pass; when the paddle is a long strip body, Because the ring and the paddle added to each of the blocking plates are in the same horizontal plane, the paddles are also above the blocking plates, and the paddle positioning grooves formed on the respective blocking plates are aligned and overlapped. Size and size Satisfying the positioning of the paddles, when the pin is rotated, when the paddle passes the position of the paddle positioning groove on the ring of the first blocking disk or the ring of the pin positioning body, the paddle is still placed at the time The second blocking disk blocks the disk, so the paddle can pass smoothly, and when the paddle passes the position of the paddle positioning groove on the second blocking disk or the position of the pad positioning groove on the ring of the pin positioning body, dial The sheet is still placed on the first barrier disk, so the paddle can pass smoothly. When the paddles on the blocking discs are aligned and positioned, the restrictions on the paddles received by the paddles can be eliminated at the same time, and inserted into the positioning slots to drive the linear movement of the pins, so that the whole rotation process is not only fluent, but also The position of the blocking disc is also constantly changing. Trying to break the code point by point becomes a random event. The success may be like letting people close their eyes on a disc to find a pinhole, because as long as the precision is high enough, The docking of the two objects can be achieved as if the points are connected to the points. In order to ensure that the mutual blocking between the barrier disks does not occur during the rotation, the frictional force can be increased by increasing the friction coefficient between the barrier disks and the cylinder to counteract the friction between the barrier disks.

As a second technical solution for realizing the basic idea of the present invention, a password-based lock password latch is composed of a latch and a latch positioning body, and the dial can be disposed on the latch positioning body, and the latch pin of the password latch a circular circular channel in the middle, a circular ring extending inward along the outer edge of the disk, two or more barrier disks placed in the ring, each blocking disk passing through the tab or a pin inserted from the ring or The blocking plate and the ratchet groove and the pawl which are mutually arranged on the side of the ring are intermittently placed on the side of the ring, and one or more protrusions and more than one pad positioning groove are arranged on each of the blocking plates, and the pin end is The button handle has two or more paddles at the end of the button handle, and the button handle on the pin passes through the pin positioning body, and the paddles pass through the aligned paddle positioning slots to allow one of the blocking plates to be placed on the front end paddle and In the annular space of the top surface of the pin positioning body, the other blocking plates are placed in the annular space formed by the two picks, and after the button is turned, the picking pieces are respectively restricted by the blocking disks.

When the latch is rotated, when the first paddle passes the position of the paddle positioning slot on the first blocking disk, the second paddle is still placed on the other paddle, so the first paddle can pass smoothly, and vice versa. When the second paddle passes the position of the paddle positioning groove on the blocking disk, the first paddle is still placed on the blocking disk where the paddle is placed, so that the second paddle can pass smoothly, so that the whole rotating process is not only fluent but also blocked. The position of the disc is also constantly changing. Trying to break the code point by point becomes a random event. The success may be like letting people close their eyes on a disc to find a pinhole, because as long as the accuracy is high enough, two The docking of objects can be achieved as if docking of points.

The positional relationship between the positioning groove of the paddles and the protrusions on the blocking plates is different, that is to say, when the paddles on the latch simultaneously push the bumps of the blocking disk to drive the blocking disks to rotate, each block The paddles on the disc are always in the position of being staggered from each other. This requires that the pin must be reversed again after the first rotation, and the paddles on the pin can be used to separately move the other blocking plates. The pad positioning groove is aligned with the paddles on the button handle, and the restriction from the pad plates can be eliminated at the same time and inserted into the positioning slot, thereby causing the pin to be linearly displaced, opening the door lock or the external lock The appearance of such a PIN pin is not aware of the position of the paddle and the locating slot, and it is impossible to blindly break the code; on the other hand, after the PIN pin is completed, the paddles on the blocking plates are spaced apart from the bumps. The geometric positional relationship of the distance is determined. As long as the zero position on the dial is changed, the password reading of the password latch can also obtain different password numbers. The password can be calculated by the numerical control machine through the programmed calculation. Automatically generated, easy to promote the use of passwords latch.

The password plug designed in this way becomes very difficult to break the code, which is convenient for the promotion and application of the password plug. Because of its simple structure and small body, it is especially suitable for all kinds of electric vehicles. Because most of the current mechanical code locks also have a plurality of password disks, each of the password disks also has a password slot, and a password slot is provided on the side of the password disk. When the password slots on the password disks are aligned, The password slot insert can be inserted into each password slot. At this time, the door handle or the key can be opened, but the password plug and each password disk It is contacted from the side of the disc. The effect of the contact is one point and not one side, because a straight line and a circle can only be tangential to one point. When the position of the password slot is just in contact with the password plug or just leaves, due to The position of the contact only appears at one point, which means that the appearance or departure of the location of the password slot is sudden and instantaneous, and it is easy to form a frustration and a slight noise, which makes it possible to detect the password.
