In order to solve the problem that the lock core security among the prior art is low, the utility model provides a lock core, tool to lock and unblock key. The lock is provided with the following lock cylinder.

A lock cylinder as shown in fig. 1 to 10, which comprises a lock case 10, a cylinder 20, a plurality of locking members 30 arranged in pairs, a plurality of locking blades 40 arranged in pairs and a locking reset member 50, wherein the cylinder 20 is rotatably arranged in the lock case 10; the locking pieces 30 are movably arranged relative to the lock cylinder 20, and the two locking pieces 30 which are arranged in pairs are respectively symmetrically arranged at two sides of the lock cylinder 20 and are switched between a locking position extending into the lock shell 10 and an unlocking position exiting from the lock shell 10; the locking blades 40 are arc-shaped and are rotatably arranged in the lock core 20 along the circumferential direction of the lock core 20, the two locking blades 40 which are arranged in pairs are respectively symmetrically arranged at two sides of the lock core 20 and respectively penetrate through the two locking pieces 30 which are arranged in pairs, the unlocking key 100 drives the locking blades 40 to switch between a stopping position and an avoiding position, when the locking blades 40 are positioned at the stopping position, the locking blades 40 lock the locking pieces 30 at the locking position, and when the locking blades 40 are positioned at the avoiding position, the locking blades 40 avoid the movement of the locking pieces 30; the locking resets 50 and wears to establish in lock courage 20, and the locking resets 50 and is located between two locking pieces 30 that the symmetry set up in pairs, and the locking resets 50 both ends respectively with two locking pieces 30 butt that the symmetry set up in pairs to for locking piece 30 provides the power of restoring to the throne that moves to the shutting position.

The locking blade 40 is provided with an arc shape, and the arc shape blade has high safety, large key amount and difficult key copying. The locking blades 40 and the locking pieces 30 are arranged on two symmetrical sides of the lock cylinder 20 in pairs, a plurality of blade mounting grooves 23 matched with the locking blades 40 are axially arranged on the side wall of the lock cylinder 20, and two locking blades 40 in pairs are mounted in the same blade mounting groove 23 on the lock cylinder 20 during mounting, so that the lock cylinder is compact in structure, high in key amount and good in anti-theft performance. The locking blade 40 wears to establish on the locking piece 30, and the locking resets 50 wear to establish in lock courage 20 and simultaneously with two locking pieces 30 butt in pairs to for two locking pieces 30 provide the power that resets, one such locking resets 50 can drive two locking pieces 30 and reset, has reduced the quantity of spare part in the lock core. The arrangement mode increases the key amount of the lock cylinder, improves the anti-theft performance and the safety of the lock cylinder, and further reduces the volume of the lock cylinder, so that the lock cylinder is compact in structure and beneficial to miniaturization of the lock cylinder.

The locking member 30 of the present embodiment is in a long strip shape, the length direction of the locking member 30 is parallel to the axial direction of the lock cylinder, a through hole 31 is formed on the locking member 30, and the locking blade 40 is inserted into the through hole 31, generally, in order to ensure the safety, the locking blades 40 are usually provided with a plurality of pairs, each pair of locking blades 40 are arranged in sequence along the axial direction of the lock cylinder, correspondingly, the lock cylinder 20 is provided with a plurality of blade mounting grooves 23, each pair of locking blades 40 is mounted in one blade mounting groove 23, based on the above arrangement, the through hole 31 of the embodiment is also provided with a plurality of pairs, and is arranged in sequence along the length direction of the locking member 30, and along the radial direction of the lock core, the distance between the two sides of the through hole 31 is greater than the distance between the two sides of the locking blade 40, thus, the locking blade 40 can rotate along the circumferential direction of the lock cylinder while passing through the through hole 31, and the locking blade 40 is prevented from being jammed in rotation. When the locking blade 40 moves to the avoiding position, the locking piece 30 can move along the radial direction of the lock cylinder, and one side of the through hole 31 can extend into the locking blade 40, so that the locking piece 30 is switched to the unlocking position.

In this embodiment, the lock core further includes blade reset piece 60, lock reset piece 50 and blade reset piece 60 are all preferably the spring, it is similar with lock reset piece 50, the both ends of blade reset piece 60 respectively with two shutting blade 40 butts that set up in pairs, thereby can provide the reset force that moves to the backstop position simultaneously for two shutting blade 40, realize two shutting blade 40 in pairs's restoration, above-mentioned mode of setting is favorable to having reduced the volume of lock core equally, make the compact structure of lock core, the assembly of blade reset piece 60 of being convenient for simultaneously.

As shown in fig. 1, 3 and 4, since the locking blade 40 moves in a rotating manner, the blade returning element 60 needs to be bent into an arc shape to be abutted to the two locking blades 40, the blade mounting groove 23 on the lock cylinder 20 is also provided with an arc shape along the outer edge of the lock cylinder 20, in order to ensure that the returning force of the blade returning element 60 reliably acts on the locking blade 40, a convex column is provided on the end portion of the locking blade 40 close to the blade returning element 60 as a guide portion 41, and the end portion of the blade returning element 60 is sleeved on the guide portion 41, thereby ensuring that the blade returning element 60 reliably returns the locking blade 40. Because the outside intercommunication of blade mounting groove 23 and lock courage 20, therefore, in order to avoid curved blade reset piece 60 atress to be extruded outside lock courage 20, it receives the influence to lead to lock courage 20 and lock shell 10 motion, it is equipped with apron 21 to add in blade mounting groove 23 department, apron 21 is the sheet metal structure, apron 21 shelters from blade mounting groove 23, and do not surpass the biggest excircle surface of lock courage 20, apron 21 also shelters from blade reset piece 60 simultaneously, can prevent that blade reset piece 60 from stretching out the biggest excircle surface of lock courage 20 and leading to blade reset piece 60 to get into in the lock shell 10, and arouse the lock core to rotate the circumstances of jam. The cover plate 21 may further include a plurality of protruding portions 211, corresponding positions on the lock core 20 are provided with fixing steps, and the protruding portions 211 may be bent and clamped in the fixing steps, so as to prevent the cover plate 21 from moving.
