Technical field

The present invention relates to level locks, in particular to the construction of a level lock containing a pin cylinder lock, and its key.

BACKGROUND OF THE INVENTION

In FIG. 1 shows a known construction of a level lock, including a housing formed by connecting the upper cover 4 and the lower cover 3, and a movable crossbar 2 located in the housing, levers 1 interacting with the deadbolt, the locking plate 7 of the level lock, tightly pressed against the levers, on the upper and the lower covers have keyholes 6 of the level lock located opposite each other, the key of the level lock has only barbs for opening the level lock, when opening the lock, the key 5 is inserted and rotates, alds are moved by means of key barbs, and the lock opens; The disadvantages of the well-known level lock can be attributed to the fact that it is characterized by a uniform design, a low number of secret key combinations, the ease of making a copy of the key, and poor resistance to opening using technical means; large lock hole size, ease of insertion of tools, poor resistance to breaking; lack of protection by locking the bolt; low security of the lock case; the key and the lock case interact directly; it is necessary to simultaneously replace the key and the lock case, and the replacement is too complicated.

SUMMARY OF THE INVENTION

The aim of the present invention is to overcome the technical disadvantages of the known level locks, such as poor resistance to opening with technical means and the difficulty of replacing, and providing the construction of a level lock containing a pin cylinder lock and its key, and due to the combination of coding of the pin cylinder lock and level lock this construction of the lever lock is distinguished by the complexity of making a copy of the key, good resistance to opening with the help of technical means, Significantly high burglar resistance, high security of use and ease of replacement of the lock.

To achieve the above objectives, the present invention adopted the following technical solution: the construction of the lever lock containing a pin cylinder lock, comprising a housing formed by connecting the upper cover and the lower cover, a movable bolt located in the housing, levers interacting with the bolt, the fixing plate of the lever lock tightly pressed to the leopard, on the upper and lower covers there are keyholes of the leveler castle located opposite each other, characterized in that in orpuse set pin cylinder lock, with the center of the keyhole of a cylinder lock and a pin centers keyholes lever locks the top cover and the bottom cover are aligned. By supplementing the cylinder pin lock, you can significantly increase the number of secret codes for the key lock and reduce the likelihood of opening the lock with a non-foreign key, increase the security of the level lock, suppose that the number of secret key codes for the pin cylinder lock is M1, and the number of key codes for the level lock is M2 , then the number of key codes of the level lock after supplementing with a pin cylinder lock is M1 × M2, when turning the key, and the pin cylinder for the lock and the lock are opened only when the corresponding beard of the key of the lever type and the undercut of the key of the pin type are simultaneously present on the inserted key, thereby opening the lock bolt by a combination of the codes of the lever lock and the pin cylinder lock; the construction of the level lock according to the invention uses two types of coding technology - coding with levers and coding with pins, which increases the complexity of making a copy of the key and opening the lock using technical means, increases the security of locking devices. The specified pin cylinder lock is made according to known technologies.

As a further improvement and addition to this technical solution, the following technical measures are also taken in the invention:

a pin cylinder lock includes a lock case and a freely rotating lock cylinder located therein, a mounting hole is made on the lock case through which a stand for fixing the bottom cover located on the bottom cover passes, holes for fixing are made on the top cover and on the lock case, for fastening by means of screws, on the lock case and on the lock cylinder in the radial direction there are several through pin channels in which the sets of pins located next to each other are installed, and in the sets of pins comrade includes locking pins, the return spring support pins set in a direction from the outside inwards in the radial through bores of the lock case, and code pins mounted in pin tumbler cylinder lock channel, wherein there is an axial keyhole in the center of the lock cylinder. By using a combination of several code pins, characterized by different sizes, it is possible to significantly increase the number of key codes for a cylinder pin lock, and reduce the likelihood of being opened with a non-native key, and generally increase the security of the lock case. The barbs of the key of a level lock designed to open the lock correspond to the levers, and the recesses of the pin-type key correspond to sets of code pins.

A washer is installed on one end of the lock cylinder, from the bottom cover side, the end surface of the other end protrudes outward along the axis and forms one buffer block, there is a keyhole on the washer corresponding to the lock cylinder. When opening the lock after turning the lock cylinder, the buffer block mounted on one end surface of the lock cylinder and the washer mounted on the other end surface respectively overlap the keyholes of the level lock on the upper and lower covers, and cover most of the keyhole gaps except the key rod inserted into the center of the keyhole, which prevents illegal opening by inserting any tools, thus improving the resistance to opening using technical means units This can block all keyholes of a level lock made on both sides of the castle, facilitates installation, and installation of the castle does not require environmental considerations.

Between the lock cylinder and the deadbolt there is a locking mechanism for the levers, jointly operating with the lock cylinder, the locking mechanism for the suvald contains a plate for engagement with a bolt and a locking plate mounted on a fixing plate for a level lock, a hole for fixing is made at one end of the plate for engaging with a bolt, corresponding to the stand for fixation, located on the crossbar, on both sides of the other end, guide pins are installed, respectively included in the guide grooves located on the fi on the levitating plate of the level lock and on the top cover and moving in the direction of movement of the bolt, on the side of the plate for engaging the bolt directed towards the pin cylinder lock, grooves are made in the direction along the guide groove, in the middle of the locking plate there are two sliding guides located perpendicularly a guide groove and matching with a stand for fixing the bottom cover and a pin for fixing located on the fixing plate of the level lock, one end of the locking plate is configured locking protrusion corresponding to the shape of the groove, between the other end and a spring lower cover locking plate, a buffer unit, mounted on the end face of the lock cylinder is an eccentric, on the side of the closure plate is arcuate working surface corresponding to the eccentric. The locking mechanism of the suvald is designed to lock and limit the bolt, and in order to open the lever lock, first of all, it is necessary to release the bolt from the restriction, similarly when locking the bolt it is necessary to limit the bolt. The working process of the suvald locking mechanism is as follows: when the key is turned, the lock cylinder moves and the lock opens by touching the arc-shaped working surface with an eccentric located on one end surface of the lock cylinder, which pushes the locking plate and gradually increases the distance of movement, during the movement the locking plate gradually compresses the spring of the locking plate using two sliding guides mounted on the locking plate Otherwise, the latter smoothly moves relative to the stand for fixing the bottom cover and the fixing pin located on the fixing plate of the level lock, while the locking protrusion located at one end of the locking plate, previously located in the groove for fixing the plate for engagement with the bolt, is slightly comes out of the groove, and the lever is released from locking, while further turning the key allows you to successfully open the lever lock and puts the bolt in motion; when turning the lock cylinder with the key in the opposite direction, the eccentric rotates to its original position, pushes the locking plate and reduces the travel distance, the spring of the locking plate is unclenched, pushing the locking plate back to its original locking position, the locking protrusion mounted on one end of the locking plate is again in the groove of the plate for engagement with the bolt, while the lever lock returns to the locking state.

In one of the sets of pins, one pin for changing the code is installed, located between the support pin and the code pin, there is a blind hole on the side wall of the lock cylinder corresponding to the pin for changing the code, the blind hole and the pin for changing the code are in the same radial plane , increasing the pin to change the code facilitates changing the code of the pin cylinder lock, if you need to replace the lock, you do not need to replace the lock case, to change the code of the pins you just need to insert another key and turn it, after that the lock can be opened only with the same key having the corresponding undercut under the pin lock. For example, former keys A and B can be inserted into the lock, however, when inserting key A, the pin for changing the code is located in the lock cylinder, and when inserting key B, the pin for changing the code is located in the lock case, both keys can open the lock; if it is necessary to change the code, the key B is inserted into the lock and rotated by a certain angle, after which, when pushing the return spring, the pin for changing the code enters the blind hole made on the lock cylinder and remains forever in it, at this time the pin code of the pin cylinder lock changes, and then only the corresponding key B can be used, key A is not valid and cannot open the lock, and thus the key code A is changed by key code B.

The present invention also provides a key used in conjunction with a level lock design comprising a pin cylinder lock, comprising a key rod and key lock barrels symmetrically mounted on both sides of the key on end surfaces in its front part, characterized in that on the key body between the barbs a lever lock installed on both sides of the key, a groove of a pin type key corresponding to a pin cylinder lock is made. By performing the key type key undercut corresponding to the cylinder pin lock on the key body, such advantages as doubling the number of key codes, good resistance to opening by technical means are achieved.

The groove of the pin type key is a groove having several rows and several combinations. The groove of a pin-type key, having several rows and several combinations, is used in conjunction with a pin cylinder lock having a pin to change the code, without changing the lock case, you can change the code by replacing one key with another.

By installing a pin cylinder lock in a known lever lock and due to a combination of pin coding and lever coding, the present invention increases the complexity of making a key copy and opening using technical means; the joint work of the pin cylinder lock with the suvald locking mechanism locks the bolt, along with this, when the lock is opened, the open sections of the keyhole overlap, which increases resistance to cracking, and the use of the locking device becomes more secure; if it is necessary to replace the lock, it is not necessary to replace the lock case, only the key that is used together with the pin to change the code must be replaced.
