Description

The theftproof lock bag

The utility model relates to a kind of lockset.

Existing a kind of bolt lock of wearing, particularly be loaded on the bolt lock of wearing on the double door, form by the tightening latch that is loaded on the borehole jack on the Yishanmen and be loaded on other Yishanmen, there is a lockhole end of tightening latch, tightening latch is inserted in the borehole jack, again the U-shaped clasp of a padlock is penetrated in the lockhole padlock is locked, double door can be locked.This lockset is simple, but its fastness, safety are not satisfactory, and the robber is easy to strike padlock bad and door is opened.

Task of the present utility model is the shortcoming that overcomes above-mentioned lockset, provides a kind of and padlock can't be struck the bad theftproof lock bag that lockset is opened.

Task of the present utility model is finished like this: it has a Hu Bao and a tightening latch, protecting bag is one and has a lateral opening at least, the chamber shape part of other face envelope shelves, its big face has the hole that can insert tightening latch, gapped between tightening latch that inserts and the chamber sidewall, there is notch the tightening latch end towards a side who protects bagmouths open.The padlock that an appearance and size and Hu Bao chamber size match is put into the chamber, the U-shaped clasp of padlock is entered in the gap of tightening latch and chamber wall, the keyhole of padlock bottom exposes from opening, to there be the tightening latch end of notch to insert in the tightening latch hole then, padlock is locked, the lock body of padlock is snapped in the notch of tightening latch, and tightening latch promptly is lockable, and can't withdraw from from latch arm hole.

The tightening latch hole can be made into and connects the through hole protect two big relatively of bags, also can make a pit that can allow the tightening latch termination sink at the big face relative with the hole only on a big face, protects in the bag so that the tightening latch end all is enclosed in.

The other end of Hu Bao side and tightening latch also can firmly be connected with the two ends of a wire rope or chain respectively, thereby makes an antitheft Steel wire rope lock or mild steel safeguard chain lock.

The side of protecting bag also can be affixed with an end of a straight-bar, tightening latch is made a U-shaped bar, the other end of the other end of straight-bar and U-shaped tightening latch is mutually hinged with hinge, when U-shaped tightening latch and straight-bar relatively rotate, the tightening latch hole of protecting bag can be inserted or withdraw from the tightening latch end smoothly, thereby make a firmly reliable motorcycle, the hinged U-shaped theftproof lock of for bicycle.

Because the utility model has a chamber shape to protect bag, padlock is hidden in and protects in the bag during use, and the notch of tightening latch is blocked by firm padlock body, thereby after padlock was locked, padlock was difficult for being struck bad, and tightening latch also is difficult to separate with protecting bag, locks very firm reliable.When padlock residual old or when giving away secrets, the padlock that available another standard specification is identical is replaced.

Be elaborated below in conjunction with embodiment and accompanying drawing.

Fig. 1 is the existing schematic diagram of wearing bolt lock.Fig. 2 is the schematic diagram of the utility model in opening, and Fig. 3 is the utility model locking states sectional view.Fig. 4 is the schematic diagram that the utility model is made Steel wire rope lock.Fig. 5 is the schematic diagram that the utility model is made hinged U-shaped lock.

In Fig. 2 and Fig. 3, the bag 1 that protects of the present utility model is one five envelope shelves, the chamber shape part of an opening.There is notch 3 end of tightening latch 2.The last big face 4 that protects bag 1 has the hole 5 that adapts with the tightening latch end.The direction of notch 3 is identical with the direction of the opening 6 in Hu Bao chamber, and gapped 7 between the tightening latch of patchhole 5 and the Hu Bao chamber sidewall, the padlock 8 of a corresponding specification is put in the Hu Bao chamber just, and 7 in gap holds the U-shaped clasp 9 of padlock just.With protect relative following big 10 of bag 1 last big face 4 pit 11 arranged, can hold the termination 12 of tightening latch 2, the end of tightening latch 2 is enclosed in the Hu Bao chamber.After padlock locked, the lock body of padlock 8 snapped in the notch 3 of tightening latch 2 (as shown in Figure 3) just, and tightening latch just can't be pulled out from the hole 5 of protecting bag.The notch 3 of padlock 8 and tightening latch 2 and termination 12 all wrap in the Hu Bao chamber, and only padlock has the bottom of keyhole to expose from the opening that protects bag 1.

Protect the side 13 of bag 1 and an end firm welding of wire rope 14 as seen from Figure 4, the other end firm welding of the other end of tightening latch 2 and steel cable 14 constitutes one Steel wire rope lock.

By shown in Figure 5, the side 13 of protecting bag 1 is connected with a straight-bar 15, and tightening latch 2 is a U-shaped bar, and the one end has notch, and the other end of its other end and straight-bar 15 has hinge 16 hinged, constitutes one hinged U-shaped lock.When U-shaped tightening latch 2 and straight-bar 15 relatively rotate, the U-shaped tightening latch have the notch end to pass in and out smoothly to protect a tightening latch hole 5 in the big face 4 on the bag 1.In the Hu Bao chamber, put into a suitable padlock and locked after, promptly can not relatively rotate between tightening latch and straight-bar.

Also can pack to become to have the chamber shape part that respectively there is an opening two mutually perpendicular sides or two mutual parallel sides with protecting, can put into two padlocks respectively from both direction in the chamber, respectively there is being a notch tightening latch end towards the direction of protecting bagmouths open, whenever can snap in the lock body of padlock in the corresponding notch.Even also can pack into three and be mutually the chamber shape part that respectively there is an opening 90 ° side protecting, there are three corresponding notches the tightening latch end, can put into three padlocks in the Hu Bao chamber, when unblanking, must all open three padlocks, could will fasten bar and pull out from protect bag.

Of the present utility model protect the bag and tightening latch all can take processing such as case-carbonizing, quenching even hard chrome plating, so that the lockset surface is hard, inner tough, both be not easy to be fractureed, also be not easy to be cut, thus make the utlity model has simple in structure, change lock easily, strong security, anti-ly pound advantages such as the anti-saw of pick-proof theftproof performance is good.Can be used as multiple uses such as iron railings door lock, Door lock, Theft-proof iron door lock, lock for motorcycle or bicycle lock.
