Description

Position restricted and theftproof lock for active door and window

1, technical field

The utility model relates to a kind of lock, particularly position restricted and theftproof lock for active door and window.

2, background technology

At present the movable window of An Zhuaning all has lock and is used for the locking door and window, it can play certain antitheft effect and make the stranger can not get over window to enter the room, but it exists not enough and can not prevent fully that the situation of illegally entering the room from taking place, and goes into if smash glass of door and window, and existing lock is just hard to guard against.Certainly play the protective guard that also has of antitheft effect, but external fixed protective guard requires all to be removed at present in many places; There is hidden fire-fighting danger again in built-in fixed protective guard; Collapsible mobile protective guard can solve antitheft and contradiction hidden fire-fighting danger, but many heavy devices on window after all, neither attractive in appearancely also can increase too much cost.

3, utility model general introduction

The purpose of this utility model is at deficiency of the prior art, and a kind of position restricted and theftproof lock for active door and window is provided, and it is guaranteeing to also have reliable anti-theft feature under fire-fighting and the convenient situation about using.

In order to achieve the above object, the utility model is achieved in that it comprises bearing 1 and fork body 7, and its special character is that bearing 1 and fork body 7 are made by the material with sufficient intensity.Prop up and offer the retaining hole 3 of arranging at a certain distance on the seat 1, and install and fix lock body or snap close 2, be fixed with pin 4 and snap close or lock body 6 on the support arm 5 of corresponding with it fork body 7.

The utility model compared with prior art has following good effect:

Utilize the structural strength of movable window window frame itself, movable window makes its side frame constitute a guard rail before and after moving, after the utility model locking, as long as the width that the spacing of side frame can be clamp-oned less than human body, the side frame of front and back movable window just constitutes a guard rail effectively reliably.Take out fork body 7 after unblanking, movable window recovers normal again and moves.Therefore, the utility model can become movable window a reliable guard rail easily under the situation that does not increase excessive cost and complex appts, and it is that the passageway for fire apparatus that can open again can be antitheft effectively.

Fig. 1 forms schematic diagram for the utility model structure.

5, embodiment

Fig. 1 shows an embodiment of the present utility model.Wherein bearing 1, fork body 7 are made by steel with sufficient intensity or other materials.Because of each window opening size is not quite similar, so the shape of bearing 1 must be suited measures to local conditions, install and also can take multiple mode, can fix with the movable window chute, also can with windowsill or wall mounted, but require to be installed in movable window bottom or top chute side.The lock body or the snap close 2 that are fixed on the bearing 1 are the part of lockset, are used with snap close or the lock body 6 pitched on the body 7, and lockset no longer describes in detail here for existing mature technology.Offer one group of retaining hole 3 on the bearing 1, the spacing between the requirement retaining hole 3 is not more than the width of movable window.Snap close or lock body 6 fixing on the fork body 7 are a lockset part that cooperates bearing 1 upper lock body or snap close 2 to use, and are similarly prior art, no longer describe in detail.Fixing pin 4 requirements can be inserted the retaining hole 3 on the bearing 1 on the support arm 5, so the spacing of pin 4 is the spacing between the retaining hole 3, for guaranteeing reliability, the width of the whole chute of movable window is the length of pin 4 before and after choosing.

Because of requiring to offer one group of through hole that cooperates with retaining hole 3 on the underframe of each movable window or the top frame, select suitable spacing between the through hole, the be shifted distance of adjustment of each movable window of the more little expression of spacing is more little.When needs are antitheft, make its side frame constitute protective guard the displacement of front and back movable window earlier, if the width that the spacing between the side frame can be clamp-oned greater than human body, can increase more side frame by the window frame of setting up chute and add so with or without glass, the width that spacing between the guard rail that side frame constitutes can be clamp-oned less than human body, to pitch body 7 then and insert retaining hole on the bearings 1 and the through hole on each movable window underframe or the top frame, and make the lock body and snap close (2 and 6) the interlock interlocking of bearing 1 and fork body 7.Unless unblank, fork body 7 can not take out from bearing 1, and the pin 4 of insertion has limited moving of movable window again, thereby makes side frame constitute a reliable protective guard.Take out fork body 7 after unblanking, movable window recovers normal again and moves.

Claims (1)

1. a lock, particularly position restricted and theftproof lock for active door and window, it comprises bearing (1) and fork body (7), it is characterized in that: bearing (1) and pitch body (7) and made by the material with sufficient intensity.Prop up and offer the retaining hole (3) of arranging at a certain distance on the seat (1), and install and fix lock body or snap close (2), be fixed with pin (4) and snap close or lock body (6) on the support arm (5) of corresponding fork body (7) with it.
