The specific embodiment
Further specify characteristics of the present utility model below in conjunction with drawings and Examples.
When screw thread revolving type theftproof lock of the present utility model adopts the lock core structure of manually rotation situation such as Fig. 1,2,3 and shown in Figure 4, as can be seen from the figure, described theftproof lock comprise lock body 1, can be at the flexible dead bolt 2 of the left end of lock body 1, can drive the flexible screw rod 3 of dead bolt 2 and can drive the lock core transmission device 4 that screw rod 3 rotates.
Wherein, be provided with one section screw flight 6, be provided with one section lock body screw thread 7 that is complementary with it at the middle part of lock body 1, when screw rod 3 rotates in lock body 1, cooperate between the screw thread 6,7 to make screw rod 3 flexible vertically at the right-hand member of screw rod 3.Lock core transmission device 4 drives screw rods 3 and rotates during work, thus make screw rod 3 vertically push-and-pull dead bolt 2 it is stretched out or regains lock body 1, reach the purpose of locking or unlatching.As seen from the figure, lock body 1 is a rectangular structure; Dead bolt 2 is rectangular structure, only flexible vertically but can not rotate; The right-hand member of screw rod 3 is column structures, can stretches vertically when rotating; 4 of lock core transmission devices drive screw rod 3 rotations but do not have and move axially.
Be to realize These characteristics, screw rod 3 will be connected with dead bolt 2 by position limiting structure, as can be seen from the figure, is provided with circular open at the left end of dead bolt 2 and reaches the spacing hole 11 vertical with screw rod 3; The diameter of the left end unthreaded portion of screw rod 3 is less, and its circumference is provided with over against the arc groove 9 of spacing hole 11 and is provided with the right part that step 10 withstands dead bolt 2; Be the limited bolt 8 that cooperates with arc groove 9 in spacing hole 11, wherein the quantity of spacing hole and limited bolt can be 1-4 according to the size design of lock body.After adopting this structure, when screw rod 3 is stretched left, the right-hand member that its step 10 withstands dead bolt 2 with it by releasing in the lock body 1; When screw rod 3 contracted to the right, its arc groove 9 cooperated with limited bolt 8 on the dead bolt 2, and dead bolt 2 is retracted in the lock body 1.After dead bolt 2 stretches out,,, it can not be pushed back in the lock body even apply a bigger power at dead bolt 2 left ends because of the step 10 that screw front end is arranged withstands it.Certainly, the position limiting structure between screw rod and the dead bolt is not limited to this example, can also adopt other can make screw rod become axial restraint and radially rotating connected mode with dead bolt.
Between screw rod 3 and lock core transmission device 4, need to adopt and radially can not relatively rotate and axial separable connected mode, the front end of transmission device 4 is that radial section is a rectangle drive link 5 in the present embodiment, is provided with the rectangular aperture that cooperates with drive link 5 at the right-hand member of screw rod 3.Drive link reaches with it, and corresponding opening can also be triangle or other polygon.Thereby drive link 5 rotates and drives screw rod 3 rotations and flexible vertically during work, but the axial location of drive link 5 is constant.
In the present embodiment, it is disclosed lock core technology in 98113241.3 the patent document that lock core can adopt application number.As shown in Figure 1, insert key 12 and cooperates with locking mechanisms such as pellet shot from a slingshot in the lock core, manually lock core can rotate in lock body 1 during screw key 12, thereby makes 3 rotations of fixedly connected with it drive link 5 drive screw rods.If do not insert correct key, then lock core can not be rotated by locking mechanisms such as pellet shot from a slingshot are stuck, and whole lock body can not arbitrarily be opened or close by external force.
As shown in Figure 5, transmission device also can adopt motor-driven structure, comprises fixedlying connected with drive link 5 and being contained in rotating shaft 14 in the lock body 1 tail end axis hole, can driving the motor 15 of rotating shaft 14.Be to adopt automatically controlled unblanking at this moment, be applicable to the situation that lock body structure is big or Long-distance Control opens and closes,, realize unblanking or closing lock function thereby can drive rotating shaft 14 rotations by the rotating of button control motor 15 is set.This structure does not need key, but requires very high application life to motor.
As shown in Figure 6, for taking into account laborsaving and safety, transmission device can also adopt the combining structure of lock core gas-distributing motor, is at this moment will insert the key cylinder part earlier could rotate, by the rotating of button control motor 15, realize unblanking or closing lock function again thereby can drive rotating shaft 14 rotations.
In the various embodiments described above, lock body 1, dead bolt 2, screw rod 3 and transmission device all adopt high strength steel to make, and the effect that has external force resistance to destroy.
The utility model screw thread revolving type theftproof lock can be common little lock, also can be designed to the bigger large-scale lock of volume.Wherein the collapsing length of dead bolt, screw rod can be in lock body the length of the length of the rectangular aperture of axially movable length, spiro rod rear end and drive link cooperatively interact and about equally.
