Abstract
Disclosed is an anti-prizing and anti-sawing spring lock with a straight lock tongue, and the utility model which relates to a lock comprises a lock shell, a square straight lock tongue, a lock tongue box, etc. The utility model is characterized in that the outer lateral surface of the lock tongue box is an inclined surface or a cambered surface, and the draw hook position of the lock shell is provided with an anti-sawing rib simultaneously. So the purpose of the prizing prevention and the sawing prevention of the lock tongue is achieved, and the lock has the advantage of good theft prevention function.
Description
The utility model relates to a kind of lockset, further is meant a kind of latch of the anti-saw of energy pick-proof that is installed on wing in the International Classification of Patents.
The existing traditional latch (standard laid down by the ministries or commissions of the Central Government S0205-80) that generally uses, its dead bolt has the inclined-plane, is installed on the door, and one bumps promptly and closes, easy to use.But this lock band inclined-plane dead bolt is very easily supported with insertion crack between a door and its frames such as pocket knife, thin slices by the burglar and opens.Though later on the safe-guard door lock that occurs is done squarely with dead bolt and but pick-proof can not be prevented saw, and key need be inserted the lockhole rotation when locking dead bolt is stretched out, very inconvenient.
The purpose of this utility model is, designs a kind of straight-tongue latch that can the anti-saw of pick-proof, has traditional latch one and bumps the function of promptly closing, and can overcome the inclined-plane dead bolt again and easily be supported the defective of opening, and can also prevent simultaneously with the sawed-off dead bolt of saw blade, and realize antitheft.
The technical solution of the utility model is, it comprises lock housing, square straight dead bolt, dead bolt box, and its technical characterstic is that the outside of described dead bolt box is inclined-plane or cambered surface.Open the door for convenience etc., drag hook also can be set on described lock housing, and be provided with anti-saw muscle in the drag hook position of lock housing.
Description of drawings:
Fig. 1 is mounted in plan structure of the present utility model (wherein the dead bolt box the is horizontal sectional structure) schematic diagram on the locked object (as door and doorframe), and the part that woodgrain lines is arranged among the figure is locked object (as door etc.).In the drawings:
The square straight dead bolt 2-lock housing of 1-
3-dead bolt box 4-dead bolt box inclined-plane
5-drag hook and anti-saw muscle
As seen from the figure, the utility model comprises lock housing (2), is installed on square straight dead bolt (1) and dead bolt box (3) in the lock housing (2), and the square straight tongue structure of described dead bolt (1) refers to that the cross section of its flexible direction is square or regular polygon. The technical characterstic of this lock is, there is inclined-plane (4) in the outside of described dead bolt box (3), be dead bolt box (3) shown in Figure 1 with respect to lock housing (2) and dead bolt (1) be the inclined-plane with the another side of the contact-making surface of locked object, the angled α of horizontal vertical line of the flexible direction of the same dead bolt in this inclined-plane (1), the span of this angle [alpha] is 20 °～70 °. For easy to use, also can a drag hook with anti-saw muscle (5) be set in described lock housing (2), be beneficial to prevent with the sawed-off dead bolt of saw blade, and the open and close of locked object such as be convenient to. Its anti-saw muscle be one with respect to the convex tendon of lock housing end face (end that namely contact with lock box), the cross section is triangle or like triangular-arc, they are highly between 3～8 millimeters.
Operation principle of the present utility model is: when locking, described dead bolt (1) produces horizontal effect when running into the inclined-plane (4) of dead bolt box (3) and bounces back, and realizes locking. And the dead bolt of this square straight tongue structure can not be pried open with insertion crack between a door and its frames such as pocket knife, thin slices. Drag hook is convenient to hand-held and the locked objects such as open and close door, and anti-saw muscle (5) can prevent from sawing dead bolt with saw blade, and can realize antitheft.
By above accompanying drawing as can be known, the utility model had both had the function that traditional latch closes at a touch, can not push (prying open) aside or with the sawed-off dead bolt of saw blade, antitheft, easy to use with things such as pocket knife, thin slices again.
Embodiment:
According to accompanying drawing and said structure can pick-proof the straight-tongue latch of anti-saw, the angle [alpha] of its inclined-plane (4) is 45 °, dead bolt (1) stretch out place, end face right angle cavetto.The cross section of its anti-saw muscle (5) is like triangular-arc, highly is 4 millimeters.All the other adopt national ministry standard SC205-80 predetermined parameter.
Claims (4)
1, the straight-tongue latch of the anti-saw of a kind of energy pick-proof, comprise that lock housing (2) is installed on square straight dead bolt (1) and the dead bolt box (3) in the lock housing (2), it is characterized in that, there are inclined-plane or cambered surface (4) in described dead bolt box (3) outside, this inclined-plane or cambered surface (4) are 20 °～70 ° with the span of the horizontal vertical line angulation α of the flexible direction of described dead bolt (1), and are provided with anti-saw muscle (5) in the drag hook position of lock housing.
