Description
Technical field
The utility model about a kind of technology of lockset, espespecially a kind of lockset of tool anti-theft function.
Background technology
Generally traditional lockset, its tapered end is the design exposed completely, therefore burglar can use various TO tapered end very easily, because the activity space of the unlocking tool that burglar uses is unrestricted, work angle is also unrestricted, simultaneously the size of unlocking tool is also unrestricted, therefore adds the success rate that burglar goes smoothly.
Therefore, in order to reduce the success rate of burglar, more locksets have to be installed in addition additional, such as be used in row's file lock of automobile, coded lock or install several tapered end more on household's iron gate, but increase lockset and can expend the time of locking and unblanking, also relatively can cause the increase of cost, if install multiple tapered end additional at household's iron gate, also can allow gate comparatively unsightly.
Therefore, how to create and a kind ofly can limit the activity space that burglar uses unlocking tool, it is allowed to be difficult to operation, cannot operate even at all, just can reduce the success rate of burglar, or allow burglar directly give up the intention of stealing, to solve the defect on prior art, will be that the utility model institute is for actively disclosing part.
Utility model content
The purpose of this utility model is for providing a kind of lockset of tool anti-theft function, its advantage is the design utilizing a thief-proof sleeve, tapered end is enveloped, and expose a little perforate for key insertion, and be engaged the restriction of part, this thief-proof sleeve only can move in a zone of reasonableness, makes it depart from simultaneously.This design can increase the difficulty that this tapered end is unblanked, and allows the unlocking tool of burglar be difficult to operation, even cannot operate.The utility model coordinates the design of a curved key simultaneously, makes this curved key can insert this thief-proof sleeve and complete unlocking action, because general key is all vertical bar shaped structure, cannot reach the unlocking action of this case.
For achieving the above object, the utility model proposes a kind of lockset of tool anti-theft function, comprising: a tapered end and a thief-proof sleeve.Tapered end is a lockset, has anti-theft feature, tapered end comprises a keyhole, a sheathed fastener outside tapered end, and fastener has a limiting section; Thief-proof sleeve is a hollow cylinder, its head end is closed, bottom is opening, and thief-proof sleeve is installed on the outside of tapered end, and free to rotate, envelope tapered end but actual link tapered end, make tapered end be positioned at the inside of thief-proof sleeve, after installing, thief-proof sleeve is by the restriction of the limiting section of fastener, only can move in a proper range and cannot depart from, and thief-proof sleeve has a through hole, through hole inserts for key.
For achieving the above object, the utility model comprises again a curved key, and curved key has a grip portion and a key body, and grip portion is connected with key body and intersects each other in an angle, and curved key can insert the through hole of thief-proof sleeve, and opens tapered end.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, technical personnel familiar with the art can understand other advantage of the present utility model and effect easily by content disclosed in the present specification.
Referring to graphic explanation embodiment of the present utility model, it should be noted, the graphic signal for simplifying is graphic below, only basic conception of the present utility model is described in a schematic way, therefore only the structure relevant with the utility model is illustrated in graphic but not component number, shape and size drafting when implementing according to reality, it is actual when implementing, and the form of each element, quantity and ratio are not limited with diagram, work can be needed to change according to actual design, close first chat bright.
Refer to shown in Fig. 1 to Fig. 7, as shown in the figure, the lockset 1 of a kind of tool anti-theft function of the present utility model comprises: tapered end 10 and a thief-proof sleeve 20.Tapered end 10 is a lockset, has anti-theft feature, tapered end 10 comprises a keyhole 11, inserts unblank for key.A sheathed fastener 12 outside tapered end 10, fastener 12 has a limiting section 121, has limit function.
In a preferred embodiment, fastener 12 is a tubular structure, the coated outside being installed on tapered end 10, and limiting section 121 is a flange, protrudes from outside tubular structure.
Thief-proof sleeve 20 is a hollow cylinder, one head end is closed, and bottom is for open, and thief-proof sleeve 20 is installed on the outside of tapered end 10, and can rotate freely, envelope tapered end 10 but actual connection tapered end 10, make tapered end 10 be positioned at the inside of thief-proof sleeve 20, after installing, thief-proof sleeve 20 is by the restriction of the limiting section 121 of fastener 12, only can move in a proper range and cannot depart from, and thief-proof sleeve 20 has a through hole 21, through hole 21 can insert for key, and opens tapered end 10.
As shown in Figure 5, in a preferred embodiment, the bottom of thief-proof sleeve 20 has a ring edge 22 inwardly stretched, and the internal diameter of its ring edge 22 is less than the external diameter of fastener 12, makes ring edge 22 be subject to the restriction of fastener 12, and cannot depart from.
As shown in FIG. 6 and 7, the lockset 1 of a kind of tool anti-theft function of the present utility model comprises a curved key 30 further, and curved key 30 has grip portion 31 and a key body 32, and grip portion 31 is connected with key body 32 and intersects each other in an angle.The design of curved key 30, for inserting in the through hole 21 of thief-proof sleeve 20, and the keyhole 11 that body 32 inserts tapered end 10 can be held, and utilize grip portion 31 to rotate key body 32 to complete unlocking action, curved key 30 can insert the through hole 21 of thief-proof sleeve 20, and opens tapered end 10.
Preferably, grip portion 31 is connected with key body 32 and orthogonal, makes the structure of curved key 30 present L-type.And key body 32 can't be limited to any type of key, any spendable key body 32 all belongs in the scope of the claims of the present utility model.
The utility model has the advantage of, utilize the design of a thief-proof sleeve, tapered end is enveloped and exposes a little perforate and insert for key, and be engaged part and limit thief-proof sleeve and only can move in a zone of reasonableness, make it depart from simultaneously, this design can increase the difficulty that tapered end is unblanked, and allows the unlocking tool of burglar be difficult to operation and even cannot operate.The utility model coordinates the design of a curved key simultaneously, makes curved key can insert thief-proof sleeve and complete unlocking action, because general key is all vertical bar shaped structure, cannot reach unlocking action of the present utility model.
