New description: [New technical field] The creation department is about the structural improvement of the lock cylinder. It aims to provide a lock cylinder structure that can effectively limit the rotation of the lock cylinder under the closed and the lower limit. . [Prior Art] The repair of locks is an important means to ensure the safety of private property and home security, especially in the modern and prosperous economy of the industrial and commercial economy. Almost every person who goes out now carries a key, which shows the wide range of applications of locks. As shown in the first figure, it is a commonly used lock configuration, which is mainly provided on the hard disk extraction box 1 with a locking mechanism 2 for forming a card with a computer, (not shown). And a lock cylinder 3 for controlling the lock, the structure 2 is opened or not, so that the lock mechanism 2 can be opened after the lock 4 is unlocked by the key 4, thereby achieving the prevention of the removable hard disk being arbitrarily For the purpose of removal, of course, similar lock structures are often used in the anti-theft function of office drawers. In addition, the main structure and function of the lock cylinder 3 are basically composed of a casing 5 as a main body, and a lock core 6 which can be moved with the casing 5 and a tail section of the lock cylinder 6 is disposed inside the casing. Then, it is connected with a tongue piece 7 , and the lock core 6 and the outer casing 5 are arranged to restrict the relative rotation of the lock core 6 and the outer casing 5 (the figure is omitted) to lock the lock cylinder 3, or Inserting the lock cylinder 6 via the key 4 releases the restraining action of the latching member on the lock cylinder 6 and the outer casing 5, so that the lock cylinder 6 can be rotated through the key 4, so that the lock cylinder 6 tail 5 M3 51920 mobilizes the tongue of the lock mechanism 2 segment The sheet 7 is swung in a specific direction to complete the unlocking action.掣夂 与 外壳 外壳 外壳 与 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习 习, that is, you can force the anti-theft function as you should. The action of the tongue to open the lock causes it to be impossible. [New content] Provides the main purpose of this creation in the form of a lock, which can effectively limit the rotation of the lock cylinder under the lock state of improving the reliability. Borrow the structure. 』#, the inner ring of the outer casing is set up to attract the purpose. The lock of the creation is Zhao Wei. The lock core has a stopper at one end, and another lock core is sleeved on the outer casing J. The keyhole for inserting the key, the lock cylinder moves, and a tongue can be attached to the end of the 'cylinder core to δ. The related locking mechanism constitutes the purpose of unlocking or locking. ^The eye socket, the flute-PB, wherein the lock cylinder is provided with a zizi seat limit groove on its outer ring only for the relative axial sliding of the block. The end of the first limit groove is disposed near one end of the keyhole, and a stop is provided for relatively radial clearing of the passage; and another 'elastic reset element is disposed between the lock core and the outer casing to provide an orientation to the lock cylinder. The force of pushing the top of one end of the keyhole.俾When the lock cylinder is rotated until the stop of the outer casing is relatively slid into its first limit groove, the read lock restricts the rotation of the lock cylinder under the urging action of the elastic return element; the lock cylinder must be pushed into the lock cylinder by the key To shift the lock cylinder to the position where the M3 51920 stopper can slide into the channel, then the lock cylinder can be rotated, so that the tongue at the end of the lock cylinder cooperates to complete the unlocking action. One of the functions of the present invention is that the first limit slot of the lock cylinder can only be used for the relative axial displacement of the outer block of the outer rebel cylinder, and can not be moved relative to the opposite direction, so the lock cylinder can be effectively restrained in the locked state. Rotate to increase the reliability of the lock cylinder. ° The second effect of this creation is that the key turns the lock cylinder to the locked position 'and the pick-up is inserted, so that under the action of the elastic returning element, the relative axial displacement of the core allows the stop to reach the first The limit slot keeps the lock cylinder in the locked state. The third effect of this creation is that there is a second limit slot that can be placed at the channel with the first limit and the slot is in a flat configuration. After the lock cylinder is unlocked and the attack is extracted, the function of the elastic reset element can be used. Next, let the lock cylinder relative to the shaft ^ displacement to extend the second limit slot, so that _ indeed (four) is unlocked. [Embodiment] The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the examples. As shown in the first to fourth gj, the lock cylinder of the present invention is mainly composed of a package 10, a lock cylinder 20, and an elastic returning member 4;; medium: a red outer casing __ is provided with a convex Wei 11; locks the sleeves inside the double cylinder 10, and can be rotated relative to the outer casing 1G and the direction of the M3 51920, one end of the cylinder is provided with a key hole 21 for inserting the key 50, The rotation direction of the lock cylinder 20 is controlled by the key 50, and the tail end of the lock cylinder 2 is configured to be provided with a tongue 30 that cooperates when the lock cylinder 20 rotates, so as to unlock or lock the relevant lock mechanism. [The purpose of the lock cylinder 20 is provided with a first-restricted slot 22 in its outer ring. The first limiting slot 22 is disposed along the axial direction of the lock cylinder 20 and is only available for the stop 11 of the outer casing 10 to be opposite. Axial sliding in, a first end of the first limiting jaw 22 near the keyhole 21 is provided with a channel 23 disposed along the radial direction of the lock cylinder 2 to allow the shoulder block 11 of the outer casing 10 to slide radially inward. As a matter of course, the elastic restoring element 40 is disposed between the lock cylinder 2 and the outer casing 10 to provide a force for the lock cylinder 20 to push toward the end of the keyhole 21; in practice, the rear end of the lock cylinder 20 The outer diameter is smaller than the outer rim of the first limiting groove 22, so that a ring 41 is sleeved on the outer ring of the tail end of the lock cylinder 2, and the ring 41 is fixed to the outer casing 1 by the rivet 42. The elastic reset: the element 40 can be formed by a set of compression springs disposed at the upper end of the ring 41. The entire lock cylinder is rotated by the key 50 to the lock position and the key 50 is withdrawn. 'As shown in the fourth figure, the elastic reset element 40 normally pushes the lock cylinder 2 toward one end of the keyhole 21 thereof. Under the action of the top, the axial displacement of the lock cylinder 20 causes the stopper u to extend into the first limit groove 22, so that the lock cylinder is surely kept in the locked state; since the first limit groove 22 of the lock cylinder 2 is only available The load block u for the outer casing 1b is relatively axially displaced therebetween, and cannot be displaced in the direction of (four). Therefore, the lock cylinder 2 can be effectively restrained in the locked state, and the lock cylinder 2 can not be easily forcedly rotated. The reliability of the lock cylinder. M3 51920 When you want to unlock the lock cylinder, as shown in the fifth figure, you must reach the keyhole 21 of the lock cylinder 20 with the key 5〇, and push the lock cylinder 20 into the lock cylinder to make the lock cylinder 20 and the outer cylinder. 1〇 relative axial displacement until the stop 11 of the outer casing 10 can be slid into the position of the passage 23 of the lock cylinder 2, and then the key cylinder 20 is rotated by the key 50, as shown in the sixth figure, the lock cylinder can be made The tongue piece 30 at the end of the tail is engaged with the unlocking action. As shown in the third and sixth figures, the upper lock cylinder 2 can be provided with a second limiting slot 24 disposed parallel to the first limiting slot 22 at its passage 23, the second limiting position. The slot 24 is arranged to slide the passage 23 relative to the stop 11 to a position where the lock cylinder is unlocked, that is, after the lock cylinder is closed and the key 5G is withdrawn, the lock cylinder can be acted upon by the elastic return member 4〇. 2〇 The displacement is such that the block 11 is relatively extended to the second limit groove 24' so that the lock cylinder is indeed maintained. According to the above, this creation provides a better and feasible lock cylinder structure, which is based on the proposal of a new type of patent; the technical content and technical characteristics of the creation 巳 • not as above. However, those who are familiar with the technology It is still possible to make a variety of substitutions and modifications based on the creation of this novel. Therefore, the scope of protection of this creation should not be limited to those disclosed in the examples, but should include replacement and modification of the creations, and is covered by the following patent application.
