Abstract

The utility model discloses an anti-disassembly room door lock panel. The anti-disassembly room door lock panel comprises an inner panel and an outer panel, wherein the back of the outer panel is fixed with a screw, a screw hole corresponding to the screw on the outer panel is formed in the inner panel; and the anti-disassembly room door lock panel also comprises a screw pipe which is connected with the screw on the outer panel and is characterized in that the screw comprises a fixing part of which the length exceeds the outer panel and a connecting part provided with threads, and the diameter of the connecting part of the screw is smaller than that of the fixing part of the screw. By the structure, the connecting part of the screw is positioned in a door leaf, the screw pipe is sleeved on the connecting part of the screw, even a slim nose plier is inserted into a gap between the outer panel and the door leaf, only the fixing part of the screw can be clamped, and the screw pipe cannot be clamped, so that aims of breaking a key cylinder, unlocking and burglarizing cannot be fulfilled by unscrewing the screw pipe and disassembling the outer panel.

Description

Anti-dismantling door lock panel

Technical field

The utility model belongs to door lock, particularly relates to a kind of Anti-dismantling door lock panel.

Background technology

Door lock particularly lock pin door lock all is equipped with inside and outside panel inside and outside door.The mounting structure of this panel as shown in Figure 1, the back side of panel 7 is welded with the screw 4 that highly is no more than plate thickness outside, on screw 4, cover has the screwed pipe 6 of connection, position corresponding with screw 4 on wainscot 5 is provided with screw, inside and outside panel 5,7 is arranged on door leaf 1, with screw 4 from the screw of wainscot 5 pass be tightened on screwed pipe 6 with inside and outside panel 5,7 and door leaf 1 be fixed together.The door lock panel of this structure is easy to be dismantled with instrument by the thief, during crime, only need outer panels is struck distortion, insert gap between outer panels 7 and door leaf 1 with the jaw 201 (referring to Fig. 1, Fig. 2) of thin mouth pincers 2, clamp screwed pipe 6 and unscrew and the outer panels dismounting can be reached the purpose that the destruction lock core is unblanked burglary.

The utility model content

The purpose of this utility model is to provide a kind of Anti-dismantling door lock panel that is difficult to dismantle.

The technical scheme that realizes the employing of the utility model purpose is as follows:

The Anti-dismantling door lock panel that the utility model provides comprises inside and outside panel, and the back side of outer panels is fixed with screw, and wainscot is provided with the screw corresponding with screw on outer panels, also comprises the screwed pipe that is connected with the screw of outer panels; Described screw comprises that length exceeds the standing part of outer panels and the coupling part of establishing screw thread, and the diameter that described screw connection portion is divided is less than the diameter of its standing part.

The beneficial effects of the utility model:

After the utility model adopts said structure, the coupling part of screw is positioned at door leaf, and screwed pipe is enclosed within on the coupling part of screw, even if with the gap between thin mouth pincers insertion outer panels and door leaf, also can only clamp the standing part of screw, therefore folder can't destroy the purpose that lock core is unblanked burglary by screwed pipe being unscrewed the outer panels dismounting is reached less than screwed pipe.

Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is the schematic diagram with the existing door lock of thin mouth pincers dismounting.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is structural representation of the present utility model.

The specific embodiment

See Fig. 3, the Anti-dismantling door lock panel that the utility model provides comprises inside and outside panel 5,7, and the back side of outer panels 7 is fixed with screw 4, wainscot 5 is provided with the screw corresponding with screw 4 on outer panels 7, also comprises the screwed pipe 6 that is connected with the screw 4 of outer panels 7; Described screw 4 comprises that length exceeds the standing part 401 of outer panels 7 and the coupling part 402 of establishing screw thread, and the diameter of described screw 4 coupling parts 402 is less than the diameter of its standing part 401.

As seen from Figure 3, after door lock installs, screw 3 passes from the screw on wainscot 5, be connected on screw 4 by screwed pipe 6, inside and outside panel 5,7 is fixed on door leaf 1, at this moment screwed pipe 6 is connected on the coupling part 402 of screw 4, when the gap that the jaw 201 with thin mouth pincers 2 inserts between outer panels 7 and door leaf 1, also can only clamp the standing part 401 of screw 4, folder can't destroy the purpose that lock core is unblanked burglary by screwed pipe 6 being unscrewed outer panels 7 dismountings are reached less than screwed pipe 6.

Claims (1)
