The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.
As shown in the figure, anti-theft lock and key with blade and hoodle composite construction that the utility model relates to include copper sheathing 1 and fuse 2, key 3, and said copper sheathing 1 is sleeved on the outside of fuse 2, and said key 3 is inserted in the fuse 2.
The upper end of both sides, said copper sheathing 1 front and back arc surface is respectively arranged with hoodle hole 4, in last hoodle hole 4, is provided with hoodle 5 and hoodle spring 6, is respectively arranged with blade locking key groove 7 and blade groove 8 in the both sides up and down and the left and right sides of copper sheathing 1 inwall.
Said fuse 2 be provided with said copper sheathing 1 on corresponding lower pellet hole, 4 positions, last hoodle hole 10, in lower pellet hole 10, be provided with lower pellet 11; Be respectively arranged with corresponding respectively with blade groove 8 positions with the left and right sides about the arc-shaped surface of said fuse 2 with copper sheathing 1 blade locking key groove 7; And the blade locking key groove 12 and the blade groove 13 that are connected with fuse 2 inside; The blade groove 13 of said fuse 2 left and right sides is staggered relatively; In blade locking key groove 12 and blade groove 13, be respectively arranged with blade locking key 14 and blade 15; Be provided with spring blind hole 16 above or below the said fuse 2 blade grooves 13; Leaf spring 17 is arranged in the spring blind hole 16, and an end of leaf spring 17 is pressed on spring blind hole 16 bottoms, and the other end of leaf spring 17 is pressed on the blade 15.
The opening part of the blade locking key groove 12 of said fuse 2 is provided with blade locking key spring lock block 18; Said blade locking key 14 upper ends are provided with blade locking key spring groove 19; Middle part, lower end at blade locking key 14 is provided with locating convex block 20; Be provided with blade locking key spring 21 in the said blade locking key spring groove 19; One end of blade locking key spring 21 is pressed on the blade locking key 14, and the other end is pressed on the blade locking key spring lock block 18, and the locating convex block 20 on the said blade locking key 14 is pressed on the blade 15.
Said blade 15 is the rectangular-shaped frame shape; A side place is provided with key positioner projection 22 in rectangular-shaped frame; A side is provided with spring base projection 22 above blade 15, and leaf spring 17 is pressed on the blade 15 upper spring seat projections 23, and the centre position is provided with blade detent 24 below blade 15.
The both sides of said blade 15 blade detents 24 are respectively arranged with the anti-false groove 25 of dialling.
The degree of depth of said blade 15 blade detents 24 is greater than the anti-degree of depth of dialling false groove 25.
The said last hoodle 5 that is positioned at front end is the hoodle of sealing up a door with lower pellet 11, and the outward flange of the upper limb of said lower pellet 11 and fuse 2 aligns.
Said fuse 2 end faces are provided with the king's font groove 26 along the fuse axial direction, said key 3 be set to fuse 2 on king's font key 3 of matching of king's font groove 26.
The cross sectional shape of said key 3 is horizontal king's word, and the above and below of the left and right sides of said key 3 is to mill curve of the blade tartar 27 by the computer carving, and the top in key 3 centre positions is provided with hoodle tartar 28.
Shown in figure 15; The said set hoodle tartar 28 in rear portion, key 3 top that is positioned at is the hoodle tartar 9 of sealing up a door, and the said hoodle tartar 9 of sealing up a door forms for the computer carving mills, and the lateral surface of the said hoodle tartar 9 of sealing up a door is a right angle walls 29; The said hoodle tartar 9 of sealing up a door matches with the hoodle of sealing up a door; When key 3 inserts in the fuses 2, when the hoodle of sealing up a door was corresponding with the hoodle tartar 9 of sealing up a door, the right angle walls 29 of hoodle tartar 9 sides of sealing up a door was pressed on the cambered surface of side of the hoodle of sealing up a door; Thereby controlled key 3 and inserted the degree of depth of fuse 2, inserted the effect of locating thereby played key.
Like Fig. 4 and shown in Figure 5; When key 3 inserts in the king's font groove 26 on the fuses 2; Blade tartar 27 tooth sign indicating numbers on blade 15 and the key 3 match; And act on the key positioner projection 22, make to be in staggered blade 15 and to draw close to the center, blade detent 24 snaps to the midline position of fuse 2 simultaneously; Blade locking key 14 locating convex block 20 under the effect of blade locking key spring 21 enters in the blade 15 blade detents 24; Shift out respectively with blade 15 at blade locking key groove of copper sheathing 17 and blade locking key 14 in the blade groove 8, it is mutually neat that lower pellet 11 and computer are carved the match outward flange of the top edge that moves to lower pellet 11 and fuse 2 of the hoodle tartar 28 that mills, and reverses key 3 and can open.
As shown in Figures 2 and 3; When key 3 is extracted fuse 2; Blade 15 is owing to the effect of leaf spring 17, and blade 15 enters in the blade groove 8 on the copper sheathing 1, and the locating convex block 20 on the blade locking key 14 is extruded the blade detent 24 on the blade 15; Blade locking key 14 parts enter into the blade locking key groove 7 on the copper sheathing 1 simultaneously; Last hoodle 5 and lower pellet 11 are under the effect of hoodle spring 6, and king's font groove 26 corresponding positions on the fuse 2 are withstood in the lower end of last hoodle 5, and this moment, lock core was comprehensive lock-out state.
The above is merely the preferred embodiment of the utility model, is not the protection domain that is used to limit the utility model.
