The present invention relates to a lock, and more particularly to a lock that can not be easily released by exerting a double locking force by installing a permanent magnet acting magnetically in the mechanical locking mechanism that acts mechanically.

Conventionally, there has been a lock using a mechanical lock and a permanent magnet as described in Korean Utility Model Publication (Publication No. 86-406).

However, such a lock has a complicated structure because the lock and the permanent magnet are located separately.

As shown in FIG. 6, the lock of the conventional structure first grasps the magnetic pole of the lock, and uses the counterfeit between the rotor (B) side, the stator (A) side, and the rotor (B) side. After securing the YY line by pushing the magnet (C) caught on the stator (A) side, the lock pins on the other side are pressed from the innermost lock pin (I) in the same manner as the action of the release piece represented by the virtual line. Slide the lock pin (G) to the stator (A) side. At this time, while giving the rotation force in one direction to another unlocking piece not shown is to press the lock pin (I). Then, the lock pin (I) is a thin gap formed between the rotor (B) and the stator (A), strictly speaking, is caught on the end of the rotor so that there is no blockage on the anchoring line (YY) It becomes the state to become. In this manner, the locking pin I is sequentially pressed in turn, thereby allowing the rotor B to rotate freely with respect to the stator A, thereby enabling the termination.

As described above, the conventional lock has a problem in that an arbitrary mechanism can be canceled because the lock position of the magnetic lock and the mechanical lock pin is separated.

In addition, there is a disadvantage that can be solved simply by using a pin with a strong tension and several fine tools.

In view of the above problems, the present invention forms mechanical locks and permanent magnets in the same position, so that the total length of a plurality of locks (lock pins) can be pressed no matter how long they are pressed, that is, the lock between the rotor and the stator is reduced. It is an object of the present invention to provide a lock that prevents unauthorized unlocking by allowing a lock to be positioned on a ship.

According to an embodiment of the present invention for achieving the above object, a plurality of recesses, and a key having a plurality of permanent magnets on one side thereof; A key hole is formed in the center for storing the key, and has a circular stopper near the center and a plurality of first holes disposed on both sides of the outer surface thereof, and a ring groove formed outside the bottom thereof for storing the retaining ring. A cylindrical rotor provided; A plurality of hollow agents housed in the first hole, each having a first coil spring, a permanent magnet biased by the first coil spring disposed therebetween, and a portion raised to be stopped by the circular stopper; A cylindrical stator having a two locking holes and a longitudinal hole provided in a central portion thereof for accommodating the cylindrical rotor, the cylindrical stator including a plurality of second holes corresponding to the plurality of first holes, and in the second hole. A plurality of first H-shaped locks, each of which includes hollow portions at both ends thereof for receiving the first coil spring and the permanent magnet, and a casing for accommodating the cylindrical stator and the cylindrical rotor. In the locked position, the H-shaped first locks are positioned between the rotor and the stator, and in the unlocked position the key is in the keyhole. When inserted, the grooves of the plurality of keys push out the plurality of second locks, so that the first H-shaped locks move toward the stator and the permanent magnets move to the rotor by the magnetic force of the key, causing the rotor to rotate. A lock is characterized in that the lock is released.

EXAMPLE

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an external perspective view of the present invention, and FIG. 2 is an exploded perspective view of the present invention. The lock of the present invention comprises a stator 2, a rotor 1 rotatable with respect to the stator 2, and a casing 3 into which the stator 2 is fitted.

The rotor 1 has a cylindrical shape, the overall shape of which is the shape of a cylindrical lock, and a key hole 5 into which the key is inserted is drilled in the upper side. On the outer side surface of the cylindrical rotor 1, several first holes 6 are drilled in the horizontal direction, and on the inner side of the first hole 6, a stopper 7 for blocking the second lock 13 described later. ) Is formed.

The stopper 7 is set to protrude to a predetermined length while preventing the second lock 13 from protruding inwardly into the key hole 5 as shown in FIG. 3A. The lock state and the possibility of arbitrary unlocking of the lock are reduced, that is, the lock is being upgraded.

A fixing groove 9 into which the fixing ring 8 is inserted is formed at the bottom of the rotor 1.

The stator 2 has an insertion hole 10 through which the rotor 1 is inserted, and the second hole 11 at a position coinciding with the first hole 6 of the rotor 1 on the outer surface. ) Is drilled in the horizontal direction.

In addition, the stator 2 is fitted into the stator casing 3 and is fixed. In the second hole 11 of the stator 2, the first coil spring 12, the first locking port 13, and the outer surface thereof are insulators. The permanent magnet 14, the second coil spring 15, and the second locking mechanism 16 insulated by each other are horizontally arranged and fitted. That is, the permanent magnet 14, which is a magnetic locking device, is inserted between the mechanical first locking device 13 and the second locking device 16. The longitudinal section of the first locking tool 13 has a shape of "H".

Referring to the operation of the subject innovation lock configured as described above is as follows.

3 is a partial cross-sectional view of the present invention, a is a cross-sectional view of the locked state, b is a cross-sectional view of the key is inserted into the lock open state. That is, in the state of FIG. 3A, the second hole 11 of the stator 2 and the first hole 6 of the rotor 1 coincide with each other and are fitted into the second hole 11 of the stator 2. The first lock 13 is positioned between the stator 2 and the rotor 1 by the elasticity of the first coil spring 12, thereby maintaining a predetermined lock state.

Due to the elasticity of the second coil spring 15 located between the first lock 13 and the second lock 16, the permanent magnet 14 embedded in the support 14 'is rotated with the stator 2. It is located between the electrons 1.

Thus, the lock is mechanically locked by the first lock 13 located between the stator 2 and the rotor 1 and magnetically by the permanent magnet 14.

In this state, when the key 17 is inserted into the key hole 5 of the rotor 1 as shown in FIG. 3B, the first lock and the second lock fitted to the second hole 11 of the stator 2 are inserted. The spheres 13 and 16 are exactly aligned with the line between the stator 2 and the rotor 1 while pressing the coil spring 12 by means of several recesses 18 formed in the key 17. The permanent magnet 14 sandwiched between the first lock 13 and the second lock 13 is formed between the recesses 18 of the key 17 to attract the fixed magnet 19. The second coil spring 15 is pressed to coincide with the line between the stator 2 and the rotor 1. That is, the line that is in contact with the contact surface of the stator 2 and the rotor 1 is in contact with the end of the contact line and the end of the permanent magnet 14 of the first lock 13 and the second lock 13, The rotor 1 can be rotated from the stator 2, thereby releasing the locked state of the lock.

In other words, in the locked position, the repulsive force of the first coil spring 12 is greater than that of the second coil spring 15, so that the H-shaped first locking device 13 is the rotor 1 and the stator 2. In the unlocked position where the key 17 is inserted into the key hole 5, since the plurality of key recesses 18 press the plurality of second locks 13, the H-shaped first locks. The sphere 13 moves to the stator 2 side, and the permanent magnet 14 moves to the rotor 1 side by the magnetic force of the key so that the rotor 1 can be rotated.

If the permanent magnet 19 is not formed in the state as shown in FIG. 3A, the lock 17 is inserted into the key hole 5 of the rotor 1 by inserting a key 17 having only a few recesses 18 into the rotor 1. If the second lock 6 of the stator 2 and the first hole 6 inserted into the first hole 6 of the rotor 1 are in contact with each other, The surface may coincide with the line between the stator 2 and the rotor 1, but the permanent magnet 14 sandwiched between the first lock 13 and the second lock 13 may be rotated with the stator 2. Since it is located in the line between the electrons 1, it becomes impossible to unlock the rotor 1 by rotating the rotor 1 from the stator 2 by the permanent magnet 14.

Similarly, if the lock 17 is not formed and only the permanent magnet 19 is provided with the key 17 inserted into the keyhole 5 of the rotor 1 to unlock the lock, the stator 2 The permanent magnet 14 between the first and second locks 13 and 16 fitted into the second hole 11 and the first hole 6 of the rotor 1 is the stator 2. The first lock 13 or the second lock 13 may be separated between the stator 2 and the rotor 1, although they may coincide with or deviate from the line between the rotor and the rotor 1. It is positioned so that the rotor 1 cannot be rotated from the stator 2 by the first and second locking ports 13 and 16, so that the lock cannot be released.

Hereinafter, the above operation of the present invention will be described in more detail. In other words, assuming that the tangent line between the rotor 1 and the stator 2 meets the 'ship line', as shown in FIGS. It is the greatest feature of the action.

Due to the special coincidence / unmatching action of this ship, the ship is freed and the ruled. Therefore, the operation of the present invention is divided into 1) lock time and 2) unlock time, and will be explained by dividing into ① principle explanation, ② mechanical explanation, ③ explanation according to the polar action of the permanent magnet.

1) Description of Lockheed

① Principle Explanation

Lines YY shown in Figs. 3A, 5B, and 5 are sealine. In the case of Fig. 3a, the ruled state, that is, the locked state is shown. In the case of Fig. 3b, the unlocked state, that is, the unlocked state is shown. In this drawing, the YY line is " "As in the form of the shape, since the first lock 13 is located between the unlock lines, the rotor 1 is not rotated with respect to the stator 2 and is not released. In other words, the first lock The sphere 13 is not the "ㅣ" type (straight line type), because the elastic force of the first coil spring 12 is "," ", And it prevents arbitrary rotation of the rotor 1.

② Mechanical Description

In addition, when this state is explained according to the mechanical operation of each component, the H-shaped first lock 13 is moved toward the first hole 6 of the rotor 1 by the elastic force of the first coil spring 12. Is moved. Then, the first lock 13 extends over the portion where the rotor 1 and the stator 2 are connected to each other (corresponding to the line YY in the drawing), thus preventing rotation of the rotor 1. The locking action with the stator (2). This is achieved by protruding the second locking lock 16 of the rotor 1 into the key hole 5, and when canceling, forcibly pushing out the end surface of the protruding second locking lock 16 while being H-shaped. Slide the first lock (13) to recover the YY line to "|" type to be terminated.

③ Description of the polarity of permanent magnets

As shown in FIG. 3A, the permanent magnet 14 naturally pushes the second lock 16 while pulling the H-shaped first lock 13 toward the rotor 1, and at the same time, the first coil spring ( 12). At the same time, the end face of the first lock (13) and the end face of the second lock (16) abut each other, and the second lock (16) is pushed toward the key hole (5). That is, the movement of the second lock 16 is made by pulling the permanent magnet 14 toward the rotor 1 side.

2) Explanation of Unlocking Time

① Principle Explanation

3B shows an unlocked state, that is, a state in which the lock in this compartment is released by inserting a designated key 17, and the YY line forms a "ㅣ" shape so that the rotor 1 and the stator 2 are separated. It becomes a rotatable state and shows the state which can be canceled. That is, the line where the side of the 2nd locking tool 16 and the side of the 1st locking tool 13 meet | recovers "|" (straight line type) is recovering, and arbitrary rotation of the rotor 1 is attained.

② Mechanical Description

In addition, this state is explained according to the mechanical operation of each component. When the second lock 16 is pushed to the side of the stator 2 by the designated key 17, that is, to the left in the drawing, the second lock ( 16) pushes out the first lock (13), the YY line is formed of "|" form to be restored to the state of the termination function. In other words, no parts are placed on the site where the rotor 1 and the stator 2 are connected to each other (corresponding to the YY line in the drawing), so that the rotation of the rotor 1 is freely ensured. This prevents any locking action other than the stator 2. This is because the second lock 16 of the rotor 1 pushes the end surface of the second lock 16 against the milia and the second lock 16 from the key hole 5, and the H-shaped first lock 13 By pushing, the YY line is returned to the "ㅣ" form, which is terminated.

③ Description of the polarity of permanent magnets

On the other hand, in the above mechanical description, when the second lock 16 is pushed to the left, the permanent magnet 14 and the support 14 ', and the second coil spring 15 in the loose state are the At the moment when the end surface of the first H-shaped lock 13 and one side of the permanent magnet 14 are separated by being attracted to each other by the action of the opposite polarity preset by the permanent magnet 19 embedded in both sides. The first lock 13 is restored to the original state by the first coil spring 12, and returns to the state where the YY line forms the "|" form.

In other words, the first locking device 13 is moved to the stator 2 side by the tension of the first coil spring 12, and the second locking device 16 is connected to the second coil spring by the magnetic force of the designated key 17. 15) is contracted to the rotor 1 side while being reduced in size, thereby restoring the unlocking line in a straight line, so that the rotation of the rotor 1 can be performed and the termination can be performed.

The present invention having such a function is, for example, to solve this case using any release mechanism, i.e., a mechanical method using a thin release piece having a predetermined shape called a pin or universal key. If you try to rotate the rotor (1) by making the YY line, which is the ship of the design, "ㅣ" type, this release piece is inserted into the key hole (5) to push the second lock (16). Both springs 12 and 15 are reduced as much as possible, and the other first and second locks 13 and 16, the permanent magnet 14 and the support 14 'are on the stator 2 side, i.e. It is pushed completely to the left. Then, the support pin 14 'is placed on the Y-Y line, which is the ship line, by the elasticity of the second coil spring 15, thereby preventing the rotation of the rotor 1 and making it in the state that cannot be unlocked.

Therefore, in the present invention, the unlocking is impossible unless the YY line forms a "ㅣ" anyway in order to be unlocked, and it is understood that unlocking is impossible except for the 'designated key' for both magnetic and mechanical combinations. There is a number.

This is superior to the structure that can be sufficiently canceled by a release piece (pin ring) called a universal key, as shown in FIG. There is.

In the above description, the recessed portion 18 formed in the key 17 inserted into the key hole 5 of the rotor 1 is formed of the second hole 11 and the rotor 1 of the stator 2. Assume that the first and second locking holes 13 and 16 fitted in the one hole 6 have unevenness at a height to move to a position coinciding with the line between the stator 2 and the rotor 1. The permanent magnets 19 formed between the recesses 18 of the key 17 are inserted into the second hole 11 of the stator 2 and the first hole 6 of the rotor 1. It has a polarity opposite to that of the permanent magnet 14 inserted between the first and second locking ports 13 and 16, and only when the positions of the permanent magnet 19 and the permanent magnet 14 coincide with each other. By allowing the permanent magnet 14 to be pulled, it is assumed that the permanent magnet 14 can be separated from the line between the rotor 1 and the stator 2.

Therefore, the polarity of the recessed portion 18 and the permanent magnet 19 of the key 17 inserted into the key hole 5 is the hole 5 of the stator 2 and the first hole 6 of the rotor 1. Of course, the lock cannot be unlocked when the heights of the first and second locks 13 and 16 fitted into the clash do not coincide with the polarity of the permanent magnet 19.

As described above, according to the present invention, mechanical pins and permanent magnet pins having a mechanical action and a magnetic action are configured on the same line, thereby preventing unauthorized unlocking as much as possible.
