Description

Compulsory opening of computer lock

This creation is about a "computer lock with forced opening", especially a computer lock that combines the characteristics of a combination lock core and a key lock core.

Thanks to technology, various electronic products (such as laptops or tablet computers) have a trend of being lighter, thinner, and smaller in design. However, because these electronic products are thin and light, they can be carried away in an instant, so they often become thieves. Coveted goals, especially in crowded places, or in unmanned offices, this situation is more common. In order to improve this phenomenon, the industry has developed a computer lock.

Existing computer locks generally use a key lock core for locking. If the user accidentally loses the key, the key lock core cannot be opened smoothly. To prevent this from happening, there is also a combination lock core The computer lock is available for selection. With this design, the user does not need to use the key to unlock the lock, and only needs to enter the memorized password to achieve the effect of unlocking and avoid the trouble caused by the loss of the key. However, the Relying solely on the number to switch the lock still has a certain risk of use. If the user accidentally forgets the password, it will also cause the lock core to fail to open smoothly. Therefore, it is necessary to improve the innovator.

In addition, there are many types of the electronic appliances, and the keyhole designs of electronic appliances of various brands are also different. Commonly shaped, cross-shaped or oblique hole types, and the above-mentioned keyholes are nothing more than openings. The design of the opening is smaller than the groove, so that the buckling arm of the computer lock can pass through the opening of the lock hole, and the buckling arm hooks the inside of the lock hole through the operation of the computer lock, thereby achieving the lock and anti-theft For the purpose of use, the buckle arm is fixed after it is locked in the keyhole of the electronic appliance, so the computer lock also maintains a fixed position. When applied to electronic appliances of different styles, the number wheel of the computer lock may face downward or The rear side makes it difficult for users to visually unlock, resulting in the disadvantage that it is not easy to operate.

Therefore, how to develop and improve on the shortcomings of the above-mentioned conventional computer locks is actually the goal of the relevant industry’s efforts to develop. In view of this, the creator has thought and created ideas, and designed it with years of experience. , After many discussions and trial sample tests, and many revisions and improvements, this creation is released.

The conventional computer lock has the problem of key storage, or the shortcoming that the password is easy to forget, and the unlocking angle is fixed and it is not easy to operate. This is the technical problem to be solved.

This creation provides a computer lock with forced opening, which includes: a lock shell, a combination lock core, a key lock core, a control member, a linkage block, a switching member and two fastening members, wherein the lock The shell has two opposing shells. The combination lock core and the key lock core are installed inside the two shells. A first receiving groove is formed in the front of the combination lock core in the two shells. The front of the key lock core is formed with a second accommodating groove inside the two housings, and the first accommodating groove and the second accommodating groove are A corner portion is used for conduction. The corner portion is provided with a blocking edge on one side adjacent to the second accommodating groove, and a limiting block is protruded inside the corner portion, and the first accommodating groove is The operation port penetrates the two shells laterally, and an arc-shaped ball chamber is provided in the front for the ejector rod of the control member to extend, and a penetration port for the key to be inserted is provided behind the key lock core , And one end of the two shells are jointly connected with a lock rope, the combination lock core has a lock pin that extends into the first cavity under normal conditions, and the lock pin is controlled by the combination lock The number wheel set on the heart can be used to move the lock pin to retract backward when the lock pin is unlocked by using the check number system of the number wheel, and the front end of the lock pin is equipped with an enlarged abutment plate, the key The lock core has a lock rod that extends into the second cavity under normal conditions. The lock rod is controlled by the key, so that the key is used to unlock the lock to move the lock rod back to retract, so The control member has a plate-shaped body, the ejector rod extends from the plate-shaped body, and one end is connected with a push button. , So that the push button and the ejector rod can respectively extend from the operation port and the ball chamber, and the first receiving groove and the control member are supported by a first that can push the control member forward under normal conditions. An elastic member, a reduced-diameter extension section is arranged in front of the linkage block, and the linkage block is put into the second cavity of the casing that is set in two pairs, so that the linkage block can lock the core of the key The lock rod is connected, and the extension of the lock rod is controlled by the locking of the key lock core, and the linkage block can be extended in the corner part of the two-pair housing by the extension section, A set of openings is formed in the center of the switching member, so that the switching member can be sleeved outside the limit block with the sleeve, and is supported by a second elastic member against the limit block and the sleeve opening. Between the inner walls, the switching element can be pushed sideways by the second elastic element under normal conditions, so as to use the extension section extending in the corner portion to provide the switching element as a limit position after abutment. A sliding groove is provided on the side of the switching member. The sliding groove is used to provide a sliding block for sliding. Narrative board Between the two fasteners and the control member, a hemispherical arc is formed at one end of the two fastening members symmetrically. Between the arcs, the ejector rod is in the form of a conical rod with a pointed end, and each of the two fasteners is provided with an accommodation groove for accommodating the ejector rod in an unextended state. In this state, the two fasteners are engaged The inner surface of the ball room is recessed with a ring groove, and at least one spool is protrudingly provided at the arc part of the buckling part, and the spool is slidably received in the ring groove , Thereby restricting the relative position of the buckle member and the lock shell, the other end of the buckle member penetrates the lock shell to form a buckle arm, and the lock shell is formed with an outer in the direction of the opening of the ball chamber Ring groove, and the lock shell clamps a round cover plate in the outer ring groove. The ring groove rotates relative to the round cover plate, and the two buckling arms can be moved for outward swing expansion by the push of the ejector rod, thereby obtaining a computer lock capable of forcibly opening.

(1) This creation provides a forced opening computer lock. The computer lock system has a forced opening function, so even if the lock password is forgotten, the key can be used to successfully complete the unlocking action through the key lock core.

(2) This creation provides a forced opening computer lock, which combines the characteristics of the combination lock core and the key lock core, and can reduce the situation that cannot be opened by mutual cooperation.
