Abstract

The utility model relates to a mechanical theft-proof lock means, comprising a lock head and a key. The lock head is provided with a lock head body. A rotatable lock core with a key slot is arranged inside the lock head body. The rotatable lock core and the lock head body are locked by a locking mechanism which is composed of a round head cylinder, a flat head cylinder, and a cylinder spring. The position of the key inserting hole of the lock head body is provided with a lock hole plate. The lock hole plate and the lock head body are fixedly connected into an integral body. A blocking confirming core is provided between the rotatable lock core and the lock hole plate. The blocking confirming core and the lock head body are fixedly connected. The entering hole and the discharging hole of the blocking confirming core mutually rotate and stagger an angle of 30 degrees-90 degrees. Confirming teeth which are matched with key teeth on a key are arranged on the outer wall of the inner cavity of the blocking confirming core. When the key is inserted into a lock hole, after the key enters the blocking confirming core, the key is rotated a prescribed angle, after the key passes through the confirming teeth, the key is aligned with the entering hole of the rotatable lock core, then the key is inserted into the rotatable lock core, the cylinders are jacked, and the key is rotated to open a lock. Only the key of the lock can rotate and pass through the blocking confirming core, other foreign matters can not enter, and thereby, a theft-proof purpose is realized.

Description

A kind of mechanical antitheft lock tool

Technical field

The utility model relates to a kind of lockset, particularly a kind of mechanical antitheft lock tool.

Background technology

In the prior art, mechanical lockset, tapered end and key are all arranged, described tapered end is provided with tapered end, be provided with the rotatable lock core of band spoon groove in the tapered end, pass through the round end pellet shot from a slingshot between lock core and the tapered end, the tack pellet shot from a slingshot, the locking mechanism locking that marble spring constitutes, its lock core is all inserted basically from behind, and lockhole is exposed fully, and foreign matter can directly enter in the spoon groove of lock core, and its revolution space is very big, locking mechanism between lock core and the tapered end is simple, without key, by certain technological means rotational lock core, can with comparalive ease lock be opened in the pellet shot from a slingshot alignment, so its anti-theft effect is bad.

Summary of the invention

The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of mechanical antitheft lock tool of good anti-theft effect.

The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of mechanical antitheft lock tool, it comprises tapered end and key, tapered end is provided with tapered end, be provided with the rotatable lock core of band spoon groove in the tapered end, pass through the round end pellet shot from a slingshot between lock core and the tapered end, the tack pellet shot from a slingshot, the locking mechanism locking that marble spring constitutes, be characterized in: the key insertion hole place at tapered end is provided with selvage, selvage and tapered end are fixed with one, between lock core and selvage, be provided with to deaden and confirm core, described deadening affirmation core is fixedlyed connected with tapered end, hand-hole that deaden to confirm core and the rotation mutually of portalling 30 °～90 ° angles of staggering, the outer wall that deadens the inner chamber of confirming core are provided with the affirmation tooth that cooperates with on the key key bit.The process of unblanking is: after key inserted lockhole, enters deadening affirmation core, the angle of rotation regulation after confirming tooth, was alignd with the hand-hole of lock core, inserts lock core then, and the jack-up pellet shot from a slingshot rotates lock is opened.

The technical problems to be solved in the utility model can also come further to realize by the following technical programs, deadens the hand-hole of confirming core and the rotation mutually of portalling and staggers 90 °.

The technical problems to be solved in the utility model can also come to realize that further described key is provided with key bit section and handle by the following technical programs, is provided with between key bit section and the handle and the spoon bar of confirming that core cooperates.

The technical problems to be solved in the utility model can also come further to realize by the following technical programs, have on the key bit section of described key key bit, about be provided with a spoon groove, described lockhole is provided with laterally zygomorphic bar shaped notch, deaden the inner chamber of confirming core and be provided with laterally zygomorphic two fan-shaped chambeies, the central angle in fan-shaped chamber confirms that with deadening the angle that the mutual rotation of core access hole is staggered equates.

The utility model compared with prior art, be provided with and the fixing selvage of tapered end type, selvage can't rotate, lock core is inserted by interior, between selvage and lock core, increase fixing deadening simultaneously and confirm core, deaden and confirm that in-core is provided with the affirmation tooth that cooperates with the key bit of key, have only the key of this lock could rotate, enter lock core and unblank by after confirming core.Other foreign matters enters, thereby realizes antitheft purpose.
