Description

Key and anti-theft lock

technical field

The utility model relates to the technical field of locks, in particular to a key and an anti-theft lock.

Background technique

Locks are widely used in people's daily life. At present, various locks used in families and units are still mainly pin locks. Pin locks have the advantages of simple structure, convenient manufacture, and low price. The existing pin locks use the lock cylinder rotor The pin group that can move up and down on the outside of the lock cylinder controls the rotation of the lock cylinder, and then toggles the dead bolt to open or close the lock. Due to the relatively simple structure of the existing pin lock, the pin group moves along the radial direction of the lock core when unlocking, the locking surface is an arc surface, and the lock core needs to ensure the gap between its outer surface and the inner wall of the lock core sleeve due to rotation. , resulting in lower precision of the tumbler group, criminals can easily use tools such as tin foil to unlock the lock technically, because the pin groups of the existing pin locks are arranged in a row along the length direction of the key, criminals use a master key or a hook tool Such crimes are inserted into the key of the lock cylinder, and the pins in the lock core are sequentially pushed into the lock core sleeve to open the lock easily; because the rotation of the lock core of the existing pin lock can drive the dial shaft to open the lock body. It is easy to open when it is dialed, pried, or drilled, and criminals can easily insert tools from the keyhole to forcibly destroy the lock cylinder to make it rotate, thereby opening the lock. The anti-theft performance is poor; , only three to six groups of marbles can be arranged, and the expansion and contraction range of each group of marbles is between two and four millimeters, so the number of combinations of marbles along the length of the key is limited to a certain extent, the key encryption rate of the lock is low, and the key tooth shape repetition rate is high , easy to open each other, so that people's personal and property safety is violated. In addition, there are currently more complex locks such as electronic locks and combination locks. Although their anti-theft performance is better, they are relatively easy to damage due to their high cost and complex structure, which causes certain troubles for users, especially for the elderly and the elderly. Very inconvenient for children.

Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, but should not be construed as limiting the present utility model.

An anti-theft lock and key according to an embodiment of the present utility model will be described below with reference to FIGS. 1 to 5 .

As shown in Figures 1 to 2, the utility model describes a key, including a key body 3, which is characterized in that: the front end of the key body 3 is provided with a push rod block 304 and a jacking block 305, which are located on the push rod block 304 and the jacking block 305 are provided with a front bevel 303, and the side of the key body 3 is provided with a side bevel 302, wherein the push rod block 304, the jacking block 305, the front bevel 303 and the side bevel set by the key body 3 are utilized. The hypotenuse 302 constitutes a special key and plays a role in strengthening the anti-theft effect.

In addition, a key according to the present utility model also has the following additional technical features: according to some embodiments of the present utility model, further specifically, the side hypotenuse 302 is provided with a tenon 301, and the key body 3 also has a There is a recess 306, in which the tenon 301 is matched with the recess 701. When the tenon 301 is completely embedded in the recess 701, the side bevel 302 can push the horizontal block 8 away. The purpose is to prevent similar keys from being different. Forcibly opened, it has the characteristics of special matching and reduces the same rate of key pairing. At present, none of the 1272 keys is the same by utilizing this structure, and the anti-counterfeiting and anti-theft effects are remarkable.

As shown in Figures 1 to 4, a kind of anti-theft lockset used in conjunction with the above-mentioned key includes a lock cylinder 1, which is characterized in that: the lock cylinder 1 is provided with at least one transverse block 8, the lock cylinder 1 rear end is provided with push rod 5. Use the side bevel 302 to push away the horizontal block 8 and move it to be in line with the push rod 5. The push rod block 304 on the key body 3 presses the push rod 5 to move to realize opening the lock. According to the design requirements or for To further enhance the anti-theft, two, three or four horizontal blocks 8 can be provided to achieve the above-mentioned purpose; however, the preferred solutions listed above cannot be limited accordingly.

In addition, a key according to the utility model also has the following additional technical features: according to some embodiments of the utility model, further specifically, at least one longitudinal block 7 is provided in the lock cylinder 1 . Among them, the longitudinal block 7 is provided with an anti-theft function before the push rod 5. Only when the horizontal block 8 is opened can the key body 3 be moved to the designated position, and the front bevel 303 is used to push the longitudinal block 7 away.

More specifically, the front end of the lock cylinder 1 is provided with an anti-theft panel 2, and the anti-theft panel 2 is provided with an opening 201 for the key body 3 to be inserted.

Specifically, the longitudinal block 7 is provided with at least one concave position 701, and two, three or four concave positions 701 can be provided to achieve the above purpose; however, the preferred solutions listed above cannot be limited thereby.

More specifically, the lock cylinder 1 is provided with a pressing piece 6 , one end of the pressing piece 6 is pressed on the horizontal block 8 , and the other end of the pressing piece 6 is pressed on the longitudinal block 7 . Wherein, the pressing piece 6 is elastic, which can make the horizontal locking block 8 and the longitudinal locking block 7 play a reset role.

More specifically, the rear end of the lock cylinder 1 is further provided with a sleeve 4 , the push rod 5 is located inside the sleeve 4 , and the push rod 5 is also provided with a locking position 501 , and the locking position 501 is located outside the sleeve 4 . Wherein the pipe sleeve 4 is used to limit the width of the push rod block 304, if it is not the original special key, it cannot enter the pipe sleeve 4, which plays the third anti-theft effect.

Specifically, the push rod 5 is hollow.

This structure utilizes the push rod block 304 of the key body 3, the jacking block 305, the front bevel 303 and the side bevel 302 to push away the longitudinal block 7 and the transverse block 8 in sequence, so as to push the push rod 5 to shift, and finally the The opened anti-theft lock has changed the direct twist opening method of various existing locks, and has strong anti-theft and is not easy to imitate and other problems.

As shown in Figure 5, the longitudinal block 7 is provided with a limit block 701, and the limit block 701 needs to use a special key body 3, wherein the key body 3 has a structure of a recess 306, so that the limit block 701 is placed in the recess. In the absence of 306, the key body 3 just pushes away the push rod 5. If other types of keys are used, the longitudinal block 7 is pushed to make the stop block 701 cover the entrance of the pipe sleeve 4, so that the anti-theft lock cannot be opened, thus preventing theft.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and purpose of the present invention. and modifications, the scope of the present invention is defined by the claims and their equivalents.
