Abstract
The utility model discloses a clamper lock cylinder and a matched key. The lock cylinder comprises a shell and a cylinder body that is provided with a key hole and which can rotationally match the lock cylinder. The lock cylinder is provided with a plurality of axial glide groove, the inner wall of the shell is provided with a plurality of axial long groove and a circle of lateral ring groove. The clamper with spring is positioned in the glide groove and is provided with lug bosses that is position in and match the long groove. A block piece with lug is positioned in front of the key hole and the lug is positioned inside the block piece hole of the cylinder body and movably matches the block piece to form the sealing device of the key hole. The shaped of the key body matches the key hole inside the cylinder body and the surface of the key body is provided with axial raised line that matches the long groove on the inner wall of the shell. The front place of each raised line is different and matches the corresponding clamper. Normally, the block piece blocks the orifice part of the key hole to prevent dust, slurry and other things from entering to increase the safety property of the key cylinder.
Description
Technical field: the utility model relates to a kind of lock core, also relates to a kind of supporting key.
Background technology: the keyhole oral area of general lock core opens wide, and sand and dust, mud, water etc. flow to easily, and various foreign material are also filled in easily and got lodged in the keyhole, and lock can't be opened.And, if key or other foreign material break in keyhole during use, generally just can't take out the maintenance trouble.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of sand and dust, foreign material etc. of preventing to stop up the axis lock core of keyhole, and the utility model provides a kind of supporting key simultaneously.
The core body that lock core of the present utility model comprises housing and is placed in one and is rotatably assorted, be provided with the keyhole of cylindricality in the core body, on core body, be provided with some axial chute holes, inner walls is corresponding to be provided with some axial elongated slots, and be provided with the horizontal annular groove of a circle, the axis of band spring places chute hole, axis is provided with projection and places elongated slot to cooperate, before keyhole, be provided with the catch of band lug, also be provided with the catch hole on the core body, little spring places the catch hole, and the lug of catch then places the catch hole to move cooperation formation keyhole locking device.
Matched key of the present utility model comprises the key body of cylindricality, keyhole correspondence in key body shape and the core body, the key body surface is provided with some axial raised lines and the elongated slot correspondence on the inner walls, and the front position of each raised line has nothing in common with each other, and the axis with correspondence cooperates respectively.
Catch is sealed the oral area of keyhole during usual situation, and sand and dust, mud, foreign material etc. can not enter, and can improve the security performance of lock core.During use, key inserts catch is inwardly pushed away, and the raised line on key body surface also pushes inward the axis of correspondence, and when the projection on it moved on in the annular groove of inner walls, core body was promptly rotatable, easy to use.After shifting out key, catch automatically resets, and key or other foreign material break and also can eject in keyhole like this, can not block.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the normal condition main structure schematic diagram of lock core among the embodiment;
Fig. 2 is the opening main structure schematic diagram of lock core among the embodiment;
Fig. 3 is the A-A sectional view of Fig. 2;
Fig. 4 is the main structure schematic diagram of key among the embodiment;
Fig. 5 is the upward view of Fig. 4.
Embodiment: as shown in the figure, core body 1 places housing 2 to be rotatably assorted, and is provided with the keyhole of cylindricality in the core body 1, can be made as different shapes such as cylindrical, square as required.On core body 1, be provided with some axial chute holes 3, generally establish four and get final product.Housing 2 inwalls are corresponding to be provided with some axial elongated slots 4, and general homology also is four.Housing 2 inwalls are provided with the horizontal annular groove 5 of a circle, the axis 7 of band spring 6 places chute hole 3, axis 7 is provided with projection 8 and places elongated slot 4 to cooperate, before keyhole, be provided with the catch 9 of band lug, also be provided with catch hole 10 on the core body 1, little spring places catch hole 10, and the lug of catch 9 then places catch hole 10 to cooperate formation keyhole locking device.Keyhole correspondence in key body 11 shapes and the core body 1, key body 11 surfaces are provided with elongated slot 4 correspondences on some axial raised lines 12 and housing 2 inwalls, and key body 11 surfaces generally are provided with four raised lines 12.The front position of each raised line 12 has nothing in common with each other, and the axis 7 with correspondence cooperates respectively.
During use, key inserts keyhole catch 9 is inwardly pushed away, and the raised line 12 on key body 11 surfaces also pushes inward the axis 7 of correspondence, and when the projection 8 on it moved on in the annular groove 5 of housing 2 inwalls, core body 1 is promptly rotatable unblanked.After extracting key, axis 7 and catch 9 are replied under spring action, and promptly the lockable core body 1.
