Abstract
The present invention discloses a springless vane locking cam with good theftproof performance and convenient use. The springless vane locking cam comprises a lock core which consists of vanes, a flat gasket, a columnar pin and a lock core body. The lock core is provided with a vane locking mechanism. The vane locking mechanism comprises a stop pin, an adjusting block and a restoring spring. The adjusting block is arranged between the innermost vane and the bottom of the lock core body and can move forwards and back axially. The restoring spring is arranged between the adjusting block and the lock core body. The adjusting block is fixedly connected with the stop pin. The stop pin is respectively provided with abdicating grooves and positioning ribs which have the same quantity as the vanes and are arranged oppositely to the vanes. Each vane and the flat gasket are respectively provided with a positioning groove and the abdicating groove which are matched with the positioning ribs at the stop pin. When the locking cam is locked, the adjusting block pushes the stop pin to be replaced under the action of the restoring spring, and the positioning ribs of the stop pin are clamped in the positioning grooves of the vanes, so as to lock the vanes and ensure that the vanes can not rotate.
Description
Technical field
The present invention relates to a kind of lockset, relate in particular to a kind of spring-free blade locking head.
Background technology
At present, traditional spring-free blade locking head generally is made up of lock core that is provided with stop pin mechanism and shell, the lock core that is provided with locking mechanism is made up of blade, plain cushion, straight pin and lock core body, blade can rotating certain angle in lock core body, each blade is provided with the groove of different angles, during key, by with the corresponding angle helical teeth of blade, at first driving the minimum angles blade rotates, from small to large, when all angle specification blades all alignd, straight pin entered in the groove of blade, but made lock core opposite shell rotation and unblank.The defective that above-mentioned spring-free blade locking head exists is: because blade directly can rotate in lock core body, dial the rotating vane sheet easily with foreign matter, anti-technical opening performance is not fine, in addition in use, also can rotate during external force such as blade is shaken, cause the key disunity on the blade, key needs to rotate repeatedly to insert, and uses very inconvenient.
Summary of the invention
Technical problem to be solved by this invention provides good, the easy to use spring-free blade locking head of a kind of theftproof performance.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of spring-free blade locking head, comprise by blade, plain cushion, the lock core that straight pin and lock core body are formed, described lock core is provided with the blade locking mechanism, the blade locking mechanism comprises stop pin, regulating block and back-moving spring, regulating block is arranged between the bottom of the most inboard blade and lock core body and can axially moves forward and backward, back-moving spring is arranged between regulating block and the lock core body, regulating block is fixedlyed connected with stop pin, be respectively equipped with identical on the stop pin with blade quantity and with the step down groove and the positioning bar of the corresponding setting of blade, each blade is provided with the detent that matches with positioning bar on the stop pin, and each plain cushion is provided with the groove of stepping down that matches with positioning bar on the stop pin.
The beneficial effect of spring-free blade locking head of the present invention is: because described lock core is provided with the blade locking mechanism, when extracting key and make tapered end be in locking states, regulating block promotes the stop pin return under the effect of back-moving spring, this moment, the positioning bar of stop pin snapped in the detent of blade, thereby locking-blade, when not having key insertion or key insertion not to arrive predetermined bits, blade can't rotate, key also can't rotate, and has therefore improved the theftproof performance of tapered end greatly; Because all blades can not rotate when tapered end was in locking states, therefore solved traditional spring-free blade locking head because blade rotation causes key to be difficult for the technical barrier that inserts, use very convenient.
The invention will be further described below in conjunction with the drawings and specific embodiments.

The specific embodiment
As Fig. 1, shown in Figure 2, a kind of embodiment of spring-free blade locking head of the present invention, comprise shell 3 and lock core, described lock core is by blade 5, plain cushion 6, straight pin 7 and lock core body 1 are formed, described lock core is provided with the blade locking mechanism, the blade locking mechanism comprises stop pin 4, regulating block 2 and back-moving spring 8, regulating block 2 is arranged between the bottom of the most inboard blade 5 and lock core body 1 and can axially moves forward and backward, back-moving spring 8 is arranged between regulating block 2 and the lock core body 1, regulating block 2 is fixedlyed connected with stop pin 4, be respectively equipped with identical on the stop pin 4 with blade 5 quantity and with step down the groove 4B and the positioning bar 4A of blade 5 corresponding settings, each blade 5 is provided with the detent 5A that matches with positioning bar 4A on the stop pin 4, and each plain cushion 6 is provided with the groove 6A that steps down that matches with positioning bar 4A on the stop pin 4.Move forward and backward in order to be convenient to stop pin 4 more, as Fig. 4, Fig. 5, Fig. 8, shown in Figure 9, the cross section of detent 5A on each blade 5 can be a circular arc, and the cross section of the groove 6A that steps down on each plain cushion 6 also is circular arc, and the cross section of described positioning bar 4A also is a circular arc.For the ease of fixedlying connected of regulating block 2 and stop pin 4, as shown in Figure 1, can be provided with boss 2A on the described regulating block 2, boss 2A is provided with the fixed groove 2B of lateral arrangement, and stop pin 4 is provided with the fixedly raised line 4C that matches fixedly connected with fixed groove 2B.For the ease of fixing of back-moving spring 8, the bottom centre position of described lock core body 1 can be provided with locating hole 1A, and an end of back-moving spring 8 is installed on the locating hole 1A, and the other end of back-moving spring 8 and regulating block 2 connect.
The operating principle of spring-free blade locking head of the present invention is: as Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, when tapered end is in the lock state, regulating block 2 promotes stop pin 4 and moves to assigned position backward under back-moving spring 8 effects, this moment, the positioning bar 4A of stop pin 4 just in time was stuck among the blade 5 corresponding groove 5A, and the groove 4B of stop pin 4 aims at the groove 6A of plain cushion 6, blade 5 can not be rotated under the effect of positioning bar 4A, thus locking blade 5; As Fig. 7, Fig. 8, Fig. 9, shown in Figure 10, when inserting key 9, key 9 promotes the bottom that regulating block 2 moves forward to lock core body 1, regulating block 2 drives stop pin 4 and moves forward, the positioning bar 4A of stop pin 4 leaves the groove 5A of blade 5, the positioning bar 4A of stop pin 4 aims at the groove 6A of plain cushion 6, and this moment stop pin 4 groove 4B just in time aim at the groove 5A of blade 5, thereby remove the locking of 4 pairs of blades 5 of stop pin, key 9 can drive blade 5 and rotate in the groove 4B of stop pin 4 this moment; When extracting key 9, regulating block 2 drives stop pin 4 and gets back to the grand master gage allocation under the effect of back-moving spring 8, and the positioning bar 4A of stop pin 4 snaps in again among the groove 5A of blade 5, thus locking blade 5.
