Abstract

The utility model relates to an anti-theft lock for a rolling shutter. Two lock bolts capable of telescoping towards both ends respectively are arranged in a lock shell, three rotating circular discs are arranged in parallel between the lock bolts, wherein, one circular disc in the middle and one circular disc at one end are respectively provided with a convex clamp, and the convex clamps can be matched with a plurality of grooves which are arranged on the inner side surfaces of the two lock bolts. The circular disc at both ends are respectively provided with a lock core, the lock cores are arranged oppositely, and the circular disc at one end is in gear engagement with the circular disc in the middle. Both sides in the lock are respectively provided with a safety card; one end of one safety card is hinged with the opposite end of the other safety card, and the other end of each of the safety cards is free; an elastic member capable of getting close to the middle is arranged between the safety cards; the two safety cards are also provided with safety grooves which are matched with the safety convex clamps on the two lock bolts.

Description

Rolling shutter lock

The utility model relates to a kind of theftproof lock that is used for rolling-gate.

Present rolling gate door lock safety is not high, easily pounded, outside destroy such as sled, even with once unloading a simple screwdriver with lockset from the outside.

The purpose of this utility model is to provide a kind of theftproof lock that is used on the rolling-gate for the safety that high rolling-gate lockset is provided.

Burglary-proofing lock for rolling door of the present utility model can be illustrated in conjunction with the accompanying drawings.

Fig. 1 is the structural representation of the utility model burglary-proofing lock for rolling door.In lock housing 3, be provided with two dead bolts 1 that can make expanding-contracting action respectively to opposite end.Be provided with the disk that three difference can be rotated around central axis separately side by side along the direction of its expanding-contracting action between two dead bolts 1, one of them end disc 13 band tooth, and make engaged transmission with gear forms with intermediate disc 14, the disk 7 of the other end is not with tooth.Both

ends disk

7 and 13 center axial region have one separately can drive the

lock core

12 and 16 that place disk separately rotates, and the front of this two lock core is in the opposite positive and negative two sides of lock housing, is convenient to use this theftproof lock from all available key of inside and outside two sides of rolling-gate.Two dead bolts 1 are provided with some grooves 4 separately relying on the medial surface of disk, this groove 4 can be located at a pair of

convex clip structure

10 and 17 that intermediate disc 14 and anodontia disk 7 upper edges radially are provided with separately respectively and match.With the rotation of

disk

14 and 7, the convex clip on it is hung in the groove of dead bolt successively, makes expanding-contracting action thereby drive dead bolt.On two relative side directions, also respectively be provided with a safety plate 9 at said this group disk diameter, the one end all is articulated on the lock housing with hinge 11, the other end is free end, and the hinged direction and the free end direction of this two safety plate 9 are inverse state, therebetween and be provided with and make its elastic component 8 that is close to the centre, as spring etc.The inboard of two safety plates 9 also respectively has some safety grooves 6, matches with the insurance convex clip 5 established on two dead bolts 1 respectively.When being in the state that matches therebetween, dead bolt just is positioned and can not arbitrarily stretches.Two safety plates 9 can hold the convex outer curve type 15 that the convex clip on each disk slips into having respectively with the disk 7 of band convex clip structure and 14 corresponding positions separately.When with key when lock core rotates arbitrary end disc, one in the

disk

7 or 14 is promptly rotated thereupon, convex clip structure on it slips into and outwards struts the safety plate 9 of both sides, the insurance convex clip 5 on the dead bolt promptly with safety plate on insurance groove 6 break away from and cooperate, but dead bolt just is in operating state.Along with being rotated further of key, the

convex clip structure

10 or 17 on the above-mentioned disk just can hang successively that to promote dead bolt into the inboard corresponding grooves 4 of dead bolt flexible.

Steady for the expanding-contracting action that makes dead bolt 1, can be provided with the location or the guide frame of appropriate format.As establishing a location rotating disk 18 that dead bolt is held out against in rotating shaft place of intermediate disc 14.

Anti-theft lock structure compactness, the fastness of the utility model said structure form are strong, and can open or locking from the inside and outside both sides of door, and be flexible to operation.Will be outdoors tapered end be closed in the lock box, the destructive action such as can prevent pounding, prize, dial, unloading, safety improves greatly.

Claims

1, a kind of burglary-proofing lock for rolling door, it is characterized in that in lock housing (3), being provided with two dead bolts (1) that can make expanding-contracting action respectively to opposite end, be provided with the disk that three difference can be rotated around central axis separately side by side along its direction of action between two dead bolts, wherein the disk of an end (13) is with tooth, make engaged transmission with the disk (14) of centre with gear forms, disk (7) rotating shaft place at this band tooth disk (13) and other end place is provided with separately and can drives the lock core (12) (16) that this disk rotates, and the front branch of two ends lock core is in the opposite positive and negative two sides of lock housing, two dead bolts rely on the medial surface of disk and are provided with some grooves (4) separately, this groove (4) can be located at an intermediate disc (14) and an end disc (7) respectively on a pair of convex clip structure (10) and (17) that are disposed radially match, on two relative side directions, also be provided with two safety plates (9) at said disk diameter, the one end is articulated on the lock housing through separately hinge (11) respectively, the other end is free end, and the hinged direction and the free end direction of this two safety plate (9) are inverse state, be provided with between two safety plates (9) and make its elastic component that is close to the centre (8), the inboard of two safety plates (9) respectively has some insurance grooves (6), match with the insurance convex clip (5) established on the both sides dead bolt (1) respectively, this two safety plate (9) is becoming respectively to hold the convex outer curve type (15) that convex clip slips on each disk with the corresponding position of end disc with the intermediate disc of band convex clip structure separately.

2, burglary-proofing lock for rolling door as claimed in claim 1 is characterized in that place, said intermediate disc axle center also is provided with one and can makes dead bolt (1) expanding-contracting action locate rotating disk (18) stably.
