Detailed description of the invention
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment
Composition graphs 1 and Fig. 2, a kind of safe antitheft tapered end of the present embodiment, comprise lock housing 1, lock gall 2 and thumb wheel 3, the centre of lock housing 1 offers one for installing the mounting groove of thumb wheel 3, lock gall 2 is provided with two, the both sides being installed on lock housing 1 are respectively inner, and be connected with thumb wheel 3, particularly, jump ring draw-in groove 26 (shown in Figure 6) is offered in one end that lock gall 2 is connected with thumb wheel 3, lock gall 2 stretches into the interior part of mounting groove of thumb wheel 3 after being installed on lock housing 1, its jump ring draw-in groove 26 just exposes, jump ring 4 is provided with in jump ring draw-in groove 26, for limiting lock gall 2 moving axially in lock housing 1, meanwhile, the end of lock gall 2 snaps in thumb wheel 3, when the lock gall 2 of any side rotates in lock housing 1, thumb wheel 3 all can be driven to rotate, thus stir the miscellaneous part of lock body.In addition, the length of tapered end is 40mm ~ 160mm, meets the requirement of different-thickness door body, improves the scope of application of tapered end.
As shown in Figure 3 and Figure 4, simultaneously see Fig. 5 and Fig. 6, a kind of safe antitheft tapered end of the present embodiment, its lock gall 2 there are row's stepped hole 21 and the sharp pellet accommodation hole 22 of a row along the axial distribution of lock gall 2, wherein, stepped hole 21 offers five, and sharp pellet accommodation hole 22 offers six; The endoporus inwall of lock housing 1 axially offers a clamp bar slot 11 along this endoporus, lock housing 1 there is row's spring mounting hole 15 along its axial distribution, the quantity of spring mounting hole 15 is equal with the quantity of sharp pellet accommodation hole 22, arrange six respectively in the both sides of lock housing 1, and the position of sharp pellet accommodation hole 22 can with the position one_to_one corresponding of spring mounting hole 15.When the position of sharp pellet accommodation hole 22 rotates to corresponding with the position of spring mounting hole 15, the position of stepped hole 21 is corresponding with the position of draw-in groove 11 (as shown in Figure 4).Be provided with step pellet 23 in stepped hole 21, in sharp pellet accommodation hole 22, be provided with sharp pellet 24, be provided with in spring mounting hole 15 and compress spring 13, compress between spring 13 and sharp pellet 24 and be provided with flat pellet 12.Particularly, can Stochastic choice 2 ~ 5 stepped hole 21 installation step pellets 23, after step pellet 23 is located at stepped hole 21, the unsettled certain distance in its lower end, is convenient to key and inserts; The height of point pellet 24 differs, and can random fit, adds the secret key amount of tapered end, improves safety.Compared with existing tapered end, the endoporus inwall of lock housing 1 adds a clamp bar slot 11, lock gall 2 adds row's stepped hole 21 and corresponding step pellet 23, when inserting with the key matched with this key, step pellet 23 will snap in draw-in groove 11, namely use the sharp pellet 24 of technical opening also cannot rotate lock gall 2, and then improve the theftproof performance of tapered end, make it pass through conventional technical opening.
Centre due to lock housing 1 offers one for installing the mounting groove of thumb wheel 3, makes the intermediate intensity of lock housing 1 the weakest, uses special unlocking tool easily to break disconnected from centre by lock housing 1, thus takes out tapered end, makes tapered end lose anti-theft function.Therefore, be that violence is unblanked in order to prevent people, a kind of safe antitheft tapered end of the present embodiment, lock housing safety groove 16 (as shown in Figure 5) is had at the end opens of lock housing 1, lock gall safety groove 25 (as shown in Figure 6) is had at the end opens of lock gall 2, the position of lock housing safety groove 16 is corresponding with the position of lock gall safety groove 25, like this, the weak location of tapered end is made to transfer to the end of tapered end, even if the end of tapered end by people for violence is broken disconnected, tapered end still can not lose anti-theft function, and the further picking lock of person that can stop picking lock, improve the pick-proof ability of tapered end.In order to improve the intensity in the middle part of lock housing 1, the present embodiment axially offers reinforced sheet mounting groove 14 at the middle part of lock housing 1 along lock housing 1, reinforced sheet mounting groove 14 internal fixtion is provided with some reinforced sheets 5 superimposed side by side, specifically in the present embodiment, reinforced sheet 5 can arrange 2 ~ 7, and be fixed in reinforced sheet mounting groove 14 by screw or bayonet lock, reinforced sheet 5 adopts steel disc to make, substantially increase the middle part intensity of lock housing 1, even if rupture in the middle part of lock housing 1 body, lock housing 1 still can connect as one, and prevents from artificially being twisted into two parts from centre by tapered end and losing anti-theft function.
In addition, as shown in Figure 7, in the present embodiment, key 27 both sides of lock gall 2 have additional antitheft muscle 271, make the both sides width of key 27 be less than the intermediate width of key 27, the H>h namely in figure.For the ease of the preparation of key, traditional keyhole size has formed certain standard, the width H of general keyhole is 2.5mm, the width h of key 27 both sides is further reduced to 2.1mm by the present embodiment, like this, use the key of existing thickness cannot insert key 27, thus avoid skilled unlocking, add the difficulty of reproduction of key simultaneously, further increase the theftproof performance of tapered end.
In order to understand content of the present utility model better, now provide the open theory of a kind of safe antitheft tapered end of the present utility model.
Shown in Figure 3, a kind of safe antitheft tapered end of the present utility model, during installation, stepped hole 21 upward and vertically.When key inserts key 27, tartar on the key compresses sharp pellet 24, and sharp pellet 24 is moved in its axial direction, when sharp pellet 24 is just all positioned at sharp pellet accommodation hole 22, when flat pellet 12 is just all positioned at spring mounting hole 15, spring marble mechanism opens; Position due to key opposing steps pellet 23 offers groove, and the lower end of step pellet 23 just falls within the groove of key under gravity, and now lock gall 2 just can rotate relative to lock housing 1, and tapered end is opened; If do not have corresponding groove on the key, step pellet 23 will be compressed by key and move, and the upper end of step pellet 23 snaps in draw-in groove 11, and now lock gall 2 cannot rotate, and avoids tapered end by technical unlocking.Further, the key 27 both sides width of a kind of safe antitheft tapered end of the present utility model is less than traditional key thickness, and traditional key cannot insert, and also avoids skilled unlocking to a certain extent.If adopt special unlocking tool violence to unblank, the end of tapered end can only be twisted into two parts, tapered end still cannot be opened, therefore the more existing tapered end theftproof performance of tapered end theftproof performance of the present utility model is stronger, uses safer, simultaneously easy to process, assembling is simple, with low cost, long service life.
A kind of safe antitheft tapered end of the present utility model; step pellet and traditional spring marble is utilized to realize double anti-theft protection; improve the theftproof performance of tapered end; it is made to be difficult to pass through technical opening; and can effectively prevent from using force and twist into two parts tapered end and lose anti-theft function; the key simultaneously mated with tapered end is difficult to copy, and further increases the theftproof performance of tapered end.
Below be schematically described the utility model and embodiment thereof, this description does not have restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, without creatively designing the frame mode similar to this technical scheme and embodiment, protection domain of the present utility model all should be belonged to.
